J. Dean. INTRODUCTION. The collection of hydrometric data was begun by the United States Geological Survey in 1888, when the United States Irrigation Survey was organized and a few gaging stations were established in various sections of the arid West. In 1890, stations were established in Oregon on Owyhee River at Owyhee and on Malheur River at Vale, and many discharge measurements were made. The Irrigation Survey came to an end in July, 1891, through lack of appropriations, but records were obtained at several stations in various parts of the United States, including those on Owyhee and Malheur rivers part of the time until 1895, and the division of hydrog- raphy continued in existence as a part of the topographic branch of the Survey. Since the fiscal year ending June 30, 1895, successive simdry civil biUs passed by Congress have carried appropriations for '' gaging the streams and determining the water supply of the United States * * * and for the preparation of reports upon the best methods of utilizing the water resources." The only records of stream discharge obtained in Oregon between 1895 and 1903 were relating to Owyhee and Malheur rivers, 1895 to 1897; UmatiUa River at Gibbon, where a station was established in 1896; and Deschutes River at Moro and Hood River at Tucker's bridge, 1897 to 1899. Between 1894 and 1902 discharge measure- ments were made either by engineers sent out from the Washington office of the Survey, or by Sydney Arnold, resident hydrographer for the State of Washington, who made occasional trips into Oregon, The reclamation act was passed in 1902, and as a result the Recla- mation Service was organized as a branch of the Geological Survey. In 1903 John T. Whistler was appointed district engineer for Oregon, in charge of both stream measurements and investigations under the provisions of the reclamation act. Between 1903 and 1905 many gaging stations were established, chiefly in connection with investigations of possible irrigation projects. In 1905 the Oregon Legislature passed an act providing for an annual appropriation of $2,500 for the investigation of the water 84792°— wsp 370—15 1 2 SURFACE WATER SUPPLY OF OREGON, 1878-1910. resources of the State, and a like amount for topographic mapping, contingent on the allotment of an equal amount by the Geological Survey. At the same time the office of State engineer was created and John H. Lewis, formerly of the Geological Survey, was appointed by Governor Chamberlain. With the additional funds thus made available gaging stations were established on previously unmeasured streams rising in the Cascade Mountains. This new work was carried out under the direction of the State engineer, who was designated to represent the Geological Survey, as well as the State. In the spring of 1906 J. C. Stevens was pla?ie3 in charge of all hydrometric mvestigations in Oregon under the direction of D. C. Henry, supervising engineer. In July of that year the Reclamation Service was made a separate bureau and thereafter the work was carried on entirely by J. C. Stevens. In 1910 Mr. Stevens resigned and was succeeded by F. F. Henshaw. In 1911 the Oregon Legislature appropriated $20,000 annually for hydrographic and topographic work in cooperation with the United States Geological Survey, in addition to the $5,000 annually previ- ously appropriated, and of this $7,000 has each year been spent for stream measurements. None of the results obtained from the expenditure of these additional funds appear in the present report. In 1913 the State engmeer and the Director of the United States Geo- logical Survey entered into a contract by the terms of which there were to be contributed from the State survey fund, derived from a license tax on water powers, the sum of $3,000, the Geological Survey to contribute as its share an equal sum for compiling and printing stream-flow data. In 1914 a similar contract was executed, covering $3,000 derived from the license tax for the current year. In compliance with these agree- ments the present report has been prepared. The report embraces hy- drometric data from 1878 to September 30, 1910. The results of meas- urements for the years ending September 30, 1911 and 1912, have been published m Water-Supply Papers 310, 311, 312, 330, 331, and 332. All the data here assembled have been carefully studied and the results have been recomputed when necessary to msure their best possible interpretation. For example, the daily discharge for a station may be computed the first year from a poorly defined ratmg curve; the next year, with additional measurements, a somewhat different curve may fit aU the points better without indicating that any change in channel has occurred. The second curve is therefore more truly apphcable to the gage readings of the first year than the one actually used, but in past reports covering only a given year no systematic effort has been made to revise the records of earlier years. No changes in previously published data, however, have been made uidcss apparently warranted by the accuracy of the field data. DEFINITION OF TERMS. 3 COOPERATION. Many records have been collected and furnished to the United States Geological Survey by other Government bureaus and by private corporations and individuals. Such cooperation is duly acknowl- edged in the description of the stations. Special aclaiowledgment is due to the United States Weather Bureau and the United States Engineer Corps, whose stations on Columbia River at The Dalles and Cascade Locks and on Willamette River at Albany have made available records considerably longer than any kept by the Geological Survey alone. DIVISION OF WORK. The data for this report were compiled in the Portland office of the water-resources branch of the United States Geological Survey by H. J. Dean. Rating-curve studies and comparisons of data were made by F. F. Henshaw, district engineer, and H. J. Dean. The computations were made by H. J. Dean, C. L. Batchelder, and P. V. Hodges. The report has been edited by Mrs. B. D. Wood. DEFINITION OF TERMS. The volume of water flowing in a stream — the ^'run-off" or 'Mis- charge" — is expressed in various terms, each of which has become associated with a certain class of work. These terms may be divided into two groups — (1) those that represent a rate of flow, as second- feet, gallons per minute, miner's inches, and discharge in second-feet per square mile, and (2) those that represent the actual quantity of water, as run-off in depth in inches, acre-feet, and millions of cubic feet. The principal terms used in this report are second-feet, second- feet per square mile, run-off in inches, and acre-feet. They may be defined as follows: ''Second-feet" is an abbreviation for "cubic feet per second." A second-foot is the rate of discharge of water flowing in a channel of rec- tangular cross-section, 1 foot wide and 1 foot deep, at an average velocity of 1 foot per second. It is generally used as a fundamental unit from which others are computed by the use of the factors given in the tables of convenient equivalents (pp. 4-6). "Second-feet per square mile" is the average number of cubic feet of water flowing per second from each square mile of area drained, on the assumption that the run-off is distributed uniformly both as regards time and area. "Run-off, depth in inches," is the depth to which the drainage area would be covered if all the water flowing from it in a given period were conserved and uniformly distributed on the surface. It is used for comparing run-off with rainfall, which is usuaUy expressed in depth in inches. 4 SURFACE WATER SUPPLY OF OREGON, 1878-1910. All "acre-foot" is equivalent to 43,560 cubic feet and is the quantity required to cover an acre to the depth of 1 foot. The term is commonly used in connection with storage for irrigation work. The following tenns used in this report are not in very common use: ''Discharge relation" is an abbreviation for the term ''relation of gage height to discharge." "Control," "controlling section," and "point of control" are terms used to designate that section or sections of the stream below the gage which determine the discharge relation at the gage. It should be noted that the control may not be the same section or sections at all stages. The "point of zero flov/" for a given gaging station is that pomt on the gage — the gage height — to which the surface of the river would fall if there were no flow. CONVENIENT EQUIVALENTS.

EXPLANATION OF DATA. The data presented in this report, in general, are divided into the years beginning October 1 and ending September 30 of the following year. At the 1st of January in most parts of the country a large amount of the precipitation for the preceding three months is stored, either as ground water, in the form of snow, or in lakes. This stored water passes off in the streams during the spring break-up. At the end of September the only stored water available for run-off in the streams is possibly a small amount held in ground storage. There- fore the run-off for a year, beginning with October 1, is practically all derived from precipitation occurring within that year. For each regular current-meter gaging station the following data are given: Description of the station, list of discharge measurements, table of daily gate height, table of daily discharge, table of monthly and yearly discharge and run-off. In addition to statements regarding the location and installation of current-meter stations, the descriptions give information in regard to any conditions that may affect the constancy of the discharge relation, covering such points as ice, logging, shifting channels, and backwater; also information regarding diversions which decrease the total flow at the measuring section. Statements are also made regard- ing the accuracy of the data. The table of daily gage height shows the daily fluctuations of the surface of the river as found from the mean of the gage readings taken each day, usually in the morning and in the evening, though at many stations only one reading is made each day. At a comparatively few stations automatic gages are used, some of which give a continuous record of river stage in the form of a hydrograph and others a record printed at regular intervals, from which the mean daily gage height can be computed. The gage height given in the table represents the eleva- tion of the surface of the water above the zero of the gage. All gage heights affected by the presence of ice in the streams or by backwater from obstructions are published as recorded, with suitable footnotes. The rating table is not applicable for such periods unless the proper corrections to the gage heights are known and applied . Attention is called to the fact that the zero of the gage is placed at an arbitrary ACCURACY OF FIELD DATA AND COMPUTED RESULTS. 7 datum and has no relation to zero flow or the bottom of the river. In general the zero is located somewhat below the lowest laiown surface elevation, to avoid negative readings. The discharge measurements and gage heights are the base data from which rating tables, daily discharge tables, and monthly dis- charge tables are computed. The rating table gives, either directly or by interpolation, the dis- charge in second-feet corresponding to every stage of the river re- corded during the period for which it is applicable. It is not pub- lished in this report, but can be determined from the tables of daily gage height and daily discharge. The table of daily discharge determined from the rating table gives the discharge in second-feet corresponding to the mean of the gage readings observed each day. The base data for the tables of monthly discharge presented in this report, unless otherwise stated in description of station, have been collected by the methods commonly used at current-meter gaging stations and described in standard textbooks. In the table of monthly discharge the column headed "Maximum" gives the mean flow, as determined from the rating table, for the day when the mean gage height was highest. As the gage height is the mean for the day, it does not indicate correctly the stage when the water surface was at crest height, and the corresponding discharge was consequently larger than given in the maximum column. Likewise, in the column of "Minimum" the quantity given is the mean flow for the day when the mean gage height was lowest. The column headed "Mean" is the average flow in cubic feet for each second during the month. On this the computations for the remaining columns, which are defined on pages 3 and 4, are based. ACCURACY OF FIELD DATA AND COMPUTED RESULTS. The accuracy of stream-flow data depends (1) on permanence of the discharge relation, and (2) on the accuracy of observation of stage, measurements of discharge, and interpretation of data. In order to give engineers and others information regarding the probable accuracy of the computed results, footnotes are added to the daily-discharge tables, stating the probable accuracy of the rating curves used, and an accuracy column is inserted in the monthly- discharge table. For the rating curves ^'weU defined" indicates, in general, that the rating is probably accurate within 5 per cent; '^fairly well defined," within 10 per cent; "poorly defined" or ''approximate" within 15 to 25 per cent. These notes are vcr}^ general and are based on the plotting of the individual measurements with reference to the mean rating curve. 8 SURFACE WATER SUPPLY OF OREGON, 1878-1910. The accuracy column in the monthly-discharge table docs not apply to the estimate of maximum or minimum discharge nor to that f(^r any one day, but to the monthly ]nean. It is based on the accuracy of the rating curve, the probable reliability of the observer, the number of gage readings per day, the range of the fluctuation in stage, and knowledge of local conditions. In this column, A indicates that the mean monthly flow is probably accurate within 5 per cent; B, within 10 per cent; C, within 15 per cent; D, within 25 per cent. Special conditions are covered by footnotes. Even though the montlily means for any station may represent with a high degree of accuracy the quantity of water flowing past the gage, the figures showing discharge per square mile and depth of run-off in inches may be subject to gross errors which result from including in the measured drainage area large noncontributing dis- tricts or omitting estimates of water diverted for irrigation or other use. On this account the computations of ^'second-feet per square mile" and '' run-off, depth in inches" have not been made for streams draining areas in which the annual rainfall is less than 20 inches, nor for those stations draining areas in which the precipitation exceeds 20 inches of rainfall if such computations might be uncertain or mis- leading because of the presence of large noncontributing districts in the measured drainage area, because of the omission of estimates of water diverted for irrigation or other use, or because of artificial control or unusual natural control of the flow of the river above the gaging station. For example, estimates of run-off per square mile are not given for streams east of the Cascades, practically all of which are affected by diversions, are spring fed, or drain areas wholly or partly arid, nor for the many spring-fed streams on the west side of the Cascades. The stations in Oregon for which estimates of run-off per square mile are given and the drainage area used in the computation are listed as follows : Square miles.

In general the base data collected each year by the Survey engineers are published not only to comply with the law but also to afford any engineer the means of analyzing in detail the results of the com- putations. The table of monthly discharge is so arranged as to give only a general idea of the flow at the station and should not be used for other than preliminary estimates. The determinations of daily dis- charge allow more detailed studies of the variation in flow. It should be borne in mind that the observations in each succeediag year may be expected to throw new light on data already collected and published. NATURAL, FEATURES OF OREGON.^ TOPOGRAPHY. A line of mountains — the Cascade Range — extending north and south across the State divides Oregon into a western humid region and an eastern arid region. The range merges into the Klamath Mountains on the south and extends northward, broken only by the narrow pass of Columbia River at Cascade Locks, across the State of Washington into British Columbia. Its general elevation in Oregon is less than 6,000 feet above sea level, though isolated peaks exceed 10,000 feet in altitude. Mount Hood, a volcanic peak near the northern extremity of the range in Oregon, is the highest mountain in the State and reaches an elevation of 11,225 feet.^ The range is of volcanic origin, and its slopes, especially on the west, are deeply eroded. Numerous streams, many of them excellent for power development, rise on its western slopes and most of them join Willa- mette, Umpqua, or Rogue rivers. The eastern slopes give rise to few streams. Deschutes River, parallel to the range and discharging into the Columbia above Celilo, is the largest. Between the Cascade Range and the Pacific Ocean is the Coast Range. This range was formed by uplift and distortion of the coastal plain and has been deeply dissected by erosion. It receives copious rainfall, and its valleys are traversed by many short but torrential streams. South of the Coast and Cascade ranges and merging into them is the Siskiyou Ridge of the Klamath Mountams, which has also been deeply dissected by erosion. The most important valle^^s in this 1 Chiefly from Van Winlde, Walton, Quality of the surface waters of Oregon; U. S. Geol. Survey Water-Supply Paper 363, pp. 10-13, 16, 1914. 2 Map of Mount Hood quadrangle, U. S. Geol. Survey, 1913. 10 SURFACE WATER SUPPLY OF OREGON, 18*78-1910. ridgo are occupied by Rogue, Coquille, and Illinois rivers. In the northeastern part of the State are the Blue Mountains and the Wal- lowa Mountains, in wliich the general elevation is 8,000 feet and isolated peaks rise to greater height. The most important streams flo^vulg from these mountains are Umatilla, Grande Ronde, Powder, and Silvies rivers. Many of the valleys are comparatively smooth, but because of the great dissection to which the mountams have been subjected the topography is commonly rough and broken. The central and southern parts of the State consist of a high arid plateau over which arc scattered many volcanic craters and which is so broken by cliffs and valleys that its appearance is in many places mountainous. Many of the valleys in this region contain large shallow lakes, some of which are permanent and others merely playas. The topography of the region thus includes types ranging from the chaotically wild gorges of the Snake River basin to the level sage- brush plains of the Umatilla or the rolling prairies of Willamette VaUey. Dense forests clothe the region west of the Cascades and are scattered over the better watered highlands of the interior, but the arid plains are generally treeless. A large proportion of the total area of the State is covered by the vast lava flow which stretches from Mount Shasta north into British Columbia and from the Willamette VaUey east to the upper reaches of Snake River. Its successive flows cover the country with a mantle of great thickness. It is overlain with a thick covering of volcanic ash which forms the soil over a large portion ^of the State. Over large areas in central Oregon this soil is pumiceous ; it is so loose and porous that most of the moisture reaching it passes directly into the ground and finds its way into the underlying lava rock, going finally to feed the copious springs which issue from the rocks. This occurrence of pumice overlying lava is the chief cause of the remark- able steadiness of flow of Deschutes and Klamath rivers and their tributaries. CLIMATE.! Mean temperature in Oregon differs with elevation and with dis- tance inland. In Columbia River valley and west of the Cascades at points below 2,000 feet above sea level it is approximately 52° F.; east of the Cascade Range and south of the Columbia it ranges from 43° to 51°. A universal characteristic is the uniformly low tempera- ture of the summer nights. In the coastal strip the greatest annual range in temperature is from 10° to 97°, with an average of 217 days between frosts. In the valley strip between the Coast and Cascade ranges the range is greater; maximum recorded tempera- tures for Portland and Ashland have been 102° and 108° F., respec- » Abstracted from Climatology of the United States: U. S. Dept. Agr. Weather Bur, Bull. Q, pp. 948-9C9, 1906. NATURAL FEATURES OF OREGON. 11 lively; minimum temperatures for those places have been —2° and — 4° F. The average time between last and first frosts ranges from 213 days at Portland to 179 days at Ashland. In the higher sections of this district the extremes of temperature both daily and yearly are more marked, and at Lakeview, elevation 5,060 feet above sea level, frosts have occurred every month in the year. The higher elevations of the Cascades and the Blue Mountains are subject to lower tem- peratures than those mentioned. Rainfall ranges from less than 8 inches in the southeastern part of the State to more than 138 inches in the northwestern coastal strip, and averages from 75 to 138 inches along the coast, from 20 to 45 inches in the valley region west of the Cascade Range, from 50 to 100 inches in the Cascades, from 8 to 22 inches on the central high plateau, from 10 to 15 inches in the Columbia VaUey east of the Cascades, and from 12 to 25 inches in the f oothiUs and valleys of the Blue Mountains. Maximum precipitation occurs in winter, and summers are dry. East of the Cascades there is a secondary maximum precipitation in May and June. HYDROGRAPHY. RIVERS. The principal rivers of Oregon discharge into the Pacific, either indirectly through the Columbia, as do Malheur, Owyhee, Powder, Grande Ronde, Umatilla, John Day, Deschutes, and Willamette rivers, or directly, as do Siletz, Umpqua, CoquiUe, Rogue, and Klamath rivers. (See PL I.) Most of the streams of central, south-central, and southeastern Oregon, however, discharge into the land-locked lakes of the Great Basin. Few of the rivers of this region are perennial, and the large shallow lakes that occupy the chief depressions are permanent only when evaporation is balanced or exceeded by inflow. Where surface flow is deficient intermittent lakes or playas are formed. The chief streams of the Great Basin region are Chewaucan, Ana, Donner und Blitzen, and Silvies rivers; the important lakes are Warner, Harney, Malheur, Abert, Summer, and Silver lakes. Goose Lake, in south-central Oregon and northern Caliform'a, oc- cupies a vaUey in all essential respects similar to the valleys of the Great Basin lakes, and has at present no surface outlet, but as it has, within historic times, overflowed southward into Pit River, a tribu- tary of the Sacramento, it is considered part of the San Francisco Bay drainage basin. LAKES. About 1.13 per cent of the surface of Oregon is occupied by lakes, most of which are situated in the Great Basin region or in the Cas- cade Mountains. 12 SURFACE WATER SUPPLY OF OREGON, 1878-1910. Tlio larger lakes, except Crater Lake, are situated in the central Oregon plateau region, and are subject to wide fluctuations in area. Many of them, such as the Warner Lakes and Goose Lake, are slowly diminishing as a result of deficient inflow; several, among them Mal- heur, Harney, Silver (Harney County), Goose, and the Warner Lakes, will eventually disappear, owing to the use of the tributary waters for irrigation. SWAMPS. The marshes that in places border Columbia and Willamette rivers are unimportant, but the long flat valleys of the Great Basin contain rich, fertile, swamp lands, susceptible of great development when drained. Much of Harney Valley may be classed as reclaimable swamp land, Blitzen Valley alone containing nearly 100,000 acres of marsh, most of which is now being drained. Chewaucan Marsh, below Paisley, contains more than 25,000 acres of land that has been drained and utilized for wild hay. Other important swamps are the Klamath marshes and the overflow lands of Warner Valley. Reclamation of these lands is either now under way or is contemplated. FLOODS. The rivers reach a high stage during winter, most often in January, and some rivers reach a second flood stage late in spring or early in summer. The winter flood is the normal result of increased precipi- tation in winter; the summer floods are caused by the melting of snow on the mountain slopes. Columbia River is exceptional in that its period of maximum discharge is in June, its winter discharge being relatively slight. The floods of the larger rivers are at times serious. A rise of more than 30 feet above low water has been recorded on the Willamette, and the Columbia sometimes reaches 60 feet above ex- treme low stage. COLUMBIA RIVER DRAINAGE BASIN. GENERAL FEATURES. Columbia River has its source in Columbia Lake, in the eastern divi- sion of the Kootenai district, in British Columbia, flows northwest to the fifty-second parallel of latitude, turns abruptly southward, nearly paralleling its former course, passes through a series of narrow lakes, and crosses the international boundary line near the northeast corner of the State of Washington, where it receives Clark Fork. After traversing Washington in a general southerly direction, it turns westward and forms the boundary lines between Washington and Oregon; it discharges into Pacific Ocean at the forty-sixth parallel of latitude. COLUMBIA RIVER DRAINAGE BASIN. 13 The total drainage area of the Columbia is estimated from the best available maps to be 259,000 square miles, divided as follows: Square miles. Oregon 55, 370 Washington 48, 000 Idaho 81, 380 Montana 25, 000 Nevada 5, 280 Wyoming 5, 270 British Columbia 38, 700 This area is limited on the east by the Rocky Mountains and is traversed north and south by the Cascade and Coast ranges. Be- tween the mountain ranges are rolling, rough, and mountainous table- lands. Mean altitudes range from sea level near the mouth of the river, to 8,000 feet in the Rocky Mountains, 5,000 feet in the Cascade Range, and 1,000 to 4,000 feet in the intervening table-lands. Many peaks in the mountain ranges extend into the region of eternal snow the highest in the Cascade Range, including Mount Baker (10,827 feet), Mount Rainier (14,408 feet). Mount Adams (12,307 feet). Mount Hood (11,225 feet), and Mount Jefferson (10,200 feet).

Columbia and Snake rivers were formerly navigated throughout the year, except during occa- sional blockades from it-e, from Celilo to I^ewiston. It will be noted that part of Snake River, from mouth to Riparia, is now marked "navigable under favorable conditions." COLUMBIA RIVER DRAINAGE BASIN. 15 The improvement of this river system for navigation is being car- ried on as rapidly as funds will permit. The work at present under way consists, briefly, of the deepening of the mouth of the Columbia River through the construction of jetties. In 1907 the Columbia bar had a navigable depth of approximately 26 feet at low tide; it is expected that when projects now under way are completed a depth of 40 feet may, if necessary, be obtained. The opening of the Cas- cade locks and canals to traffic in 1896 rendered the river navigable in one unit from the mouth to Big Eddy. With the completion in 1915 of the locks and canal around the obstructions between Celilo and Big Eddy, a distance of about 8| miles, the Columbia is now open to steamboat navigation from Priest Rapids to the sea — a distance of 400 miles. The area drained by the Columbia includes perhaps the largest consolidated area of forests in the world. Originally almost the entire area, except those arid portions midway between the mountain ranges, was covered with dense forests, and although the territory has been settled for about sixty-five years and large areas have been cleared, the proportion of forested area to the entire area has been reduced but slightly. It is believed that at least 45 per cent (about 116,000 square miles) of the drainage area of Columbia River is forested, and that about 58,000 square miles contain merchantable timber. The rainfall is distributed over the area most irregularly. From the Pacific coast eastward to the summit of the Coast Range the mean annual rainfall varies from 100 to 150 inches. In the basins between the Coast and Cascade ranges, it drops to about 40 inches per annum. It increases again to over 100 inches on the summit of the Cascade Range, and decreases very rapidly beyond the summit, until at the eastern base of the Cascades it has dropped to about 14 inches. At the mouth of Snake River the mean annual rainfall is about 9 inches, but this extremely low rainfall obtains only in the lower altitudes. Beyond this point the rainfall again increases in Washington and northern Idaho to about 20 inches, whereas in eastern Oregon it continues at about 9 inches or less. In the eastern areas a large proportion of precipitation appears as snow, and durmg the winter months the streams are more or less icebound. West of the Cascade Range, however, the winter stream flow is not affected by ice. The climate of the area exhibits aU the variations from the rigor- ous climate of the northern latitudes, as found in British Columbia and the higher table-lands of Oregon and Idaho, to the mild climate of western Oregon and Washington. As regards irrigation, the area ranges from the extremely arid region, where irrigation is absolutely essential, through the semi-arid country, where dry farming and irrigation are practiced side by side, to the hu- mid country that^ strictly speaking, is arid in the summer months. 16 SURFACE WATER SUPPLY OF OREGON, 1878-1910. In the Willamette Valley, for instance, where the mean annual rainfall is approximately 40 inches, only 5 per cent of this amount is received during the growing season, and the fullest agricultural de- velopment will not be realized until this entire portion of the area is brought under irrigation as completely as are the arid portions beyond the mountains. The irrigated areas of the Pacific Northwest are being extended so rapidly that it is almost impossible to keep pace with the development, and yet, comparatively speaking, a very small portion of the irrigable area has been developed. At present 1,500,000 acres of land are under irrigation in the Northwest, and this area will be more than doubled when projects now being constructed are completed. Tlie values of irrigated agricultural lands vary from about $30 per acre for the poorest qualities of hay lands to $3,000 per acre for the intensely cultivated orchards. Columbia River and its tributaries afford at least one-third of the available water powers in the entire United States, but developments along this line have scarcely begun. About 250,000 horsepower are at present developed by water power in Oregon, Washington, and Idaho. Lumbering has been the principal industry of the Northwest, and the streams of the country have therefore been used not only for water-power development but for the transportation of logs from the timbered mountain slopes to the mills and factories in the valleys below. 'Comparatively few streams, however, carry sufficient water during the summer months, and it has been necessary to build tempo- rary dams on a large number of streams, where the logs are stored until released by opening the gates in the dam. The ''splash" thus caused usually suffices to carry the logs to their destination. The highest recorded flood in the Columbia River occurred in June, 1894. The highest floods on the tributaries of this river are inva- riably caused by ''chinook" — a warm wind, usually accompanied by rain, occurring in the spring and fall. The fall ''chinook" usually brings the highest waters, since it may occur immediately after a heavy snow has covered the mountain ranges. The Columbia itself is not greatly affected at such times.

COLUMBIA RIVER DRAINAGE BASIN. 17 Bureau; read since February 1, 1892. Readings on other gages used are as follows: High- water periods, 1858 to 1877, gage of Oregon Steam Navigation Co. at Lower Cascades Landing; June 1 to December 6, 1878, gage of the United States Engineer Corps at Umatilla; December 12, 1878, to September 30, 1910, for periods when the Brooks gage was not read, gage of the United States Engineer Corps above the Cascades; October 10, 1879, to June 30, 1881, gage of the United States Engineer Corps at The Dalles. The Brooks gage has been washed out and replaced several times. It was probably checked occasionally by the United States Engineer Corps, but records of checking are not available. It was found to be correct in August, 1914. The United States Engineer Corps gage at The Dalles has been set at a number of arbitrary datums, all of which were carefully recorded ; for this report readings were all reduced to the datum of the Brooks gage. Channel. — ^Wide and deep; volcanic rock covered with sand and silt; control is rock reef at the Cascades; practically permanent. Discharge measurements. — Made as follows: In 1903, with floats and with current meter at Cayuse Rock, 7 miles below The Dalles; in 1907, with a current meter from a boat at The Dalles; in 1908, with floats at The Dalles; in 1910 and 1913, from the Northern Pacific Railway bridge just above the mouth of Snake River, the discharges of Snake, Umatilla, John Day, and Deschutes rivers at their mouths being determined from gage readings and added to the measured dis- charge to give the flow at The Dalles. In determining the mean gage height for these measurements an allowance of one day was made for the time interval between the mouth of Snake River and The Dalles. Rating curves. — Discharge estimates published in previous reports obtained by means of a rating curve based partly on two float measurements made in 1908, a coefficient of 1.05 having been used to reduce surface velocity to mean velocity. Later studies of vertical velocity curves of the Columbia indicate that a coefficient of 0.92 is more nearly correct. Rating curve adopted for revised computations passes through the two flood measurements made in 1913, close to the two float measurements made in 1908, as recomputed, and through the meter measurements made in 1907, 1910, and 1913. It averages the nine meter measurements made in 1903 and is about 5 per cent larger than the average of the float measurements of that year. Measurements made 1903 not studied by the Geological Survey, but the meter measurements are considered the more accurate. Rating curves for the gages at Cascade Locks and Umatilla have been derived from The Dalles curve by comparison of gage-height records, monthly mean gage heights for two stations being plotted as coordinates and a relation curve similar to a rating curve being drawn. Comparative plots of monthly mean gage heights were made as follows: Cascade Locks with Umatilla, Cascade Locks with Celilo, Cascade Locks with The Dalles, and The Dalles with Umatilla. These comparisons indicate a change in the control for the gage at Cascade Locks which occurred approximately June 1, 1884. The only available explanation of this change is contained in the an- nual report of Chief of Engineers, 1884, page 2246, referring to the Columbia at Cascade Locks. A large amount of blasting and excavating was done to im- prove the channel and obtain construction material, and this probably caused the change in control. Rating curve for flood gage heights at Lower Cascades Landing derived from that for Cascade Locks for 1879 to 1884 by means of a curve of relation for the same period. As high- water discharges of 1862 and 1876 are checked quite closely by high-water marks at The Dalles and Cascade Locks, estimates of volume of floods in the earlier years are probably not mate- rially in error. 84792°— wsp 370—15 2 18 SURFACE WATER SUPPLY OF OREGON, 1878-1910. Extreme stages. — The highest flood of which there is authentic record, that of June, 1894, was caused by the coincidence of floods in upper Columbia River and in Snake River, accompanied by heavy rainfall in the lower drainage area. The snowfall all over the Columbia River drainage basin had been exceptionally heavy during the previous winter. The highest stage at Cascade Locks was 49.7 feet at 4 p. m., June 6, corresponding to a discharge of 1,160,000 second-f^et, or 4.89 second-feet per square mile. The flood of 1849 may have closely approached this flood in peak discharge, but there is no authentic record of flood stage for that year. The lowest stage of which there is authentic record occurred in January, 1890, which also gives the lowest monthly mean on record. It was caused by a period of extremely cold weather following the driest year on record. The gage above the Cascades could not be read on account of ice from January 3 to 16, 1890. A reading was made on the gage below the locks January 7 and the discharge was determined from a relation of gage readings to be 41,900 second-feet. Any sudden drop in temperature when the river is low seems to cause a marked dropping off in discharge. It is probable that all the extreme low stages have been caused in this way. In the annual report of the Chief of Engineers, United States Army, for 1879 it is stated that the low water of the previous winter, 0.5 foot on January 18, 1879, which was the lowest for the preceding 10 years, was 2 to 3 feet higher than the low water of 1859 and 1862. This would seem to indicate that in the earliest years of settlement of the country there were periods during which the stage was as low as the lowest recorded stages, but probably no lower. Accuracy. — Results presented in this report considered fair for 1878 to 1884 and excellent for later periods. The area tributary to Columbia River between The Dalles and the Cascades is only about 1 per cent of the area above The Dalles, and the discharge from this intermediate area is not much more than 3 per cent of the total discharge. Variations in this intermediate inflow probably cause little inaccuracy in the results of studies of relations of gage heights. Cooperation. — Gage readings have been furnished by the United States Engineer Corps and by the United States Weather Bureau. Special acknowledgment is due to V. W. Tompkins, who has read the gage above the Cascades since 1891, and to S. L. Brooks, who read the Brooks gage from 1892 until quite recently. Mr. Brooks's earlier readings were made on his own initiative before he made any reports to the United States Weather Bureau. Discharge measurements of 1903 were furnished by the United States Engineer Corps.

SNAKE RIVER BASIN. GENERAL FEATURES. Snake River, the largest tributary of the Columbia, rises among the high peaks of the Rocky Mountains in Yellowstone National Park, western Wyoming, and eastern Idaho, heading in the divide from which streams flow northward and eastward into the Missouri, southward to the Colorado and the lakes of the Great Basin, and westward to the Columbia. From Shoshone, Lewis, and Hart Lakes, in Yellowstone National Park, the river flows southward, broaden- ing into Jackson Lake (4 miles wide and 18 miles long) and passing through Jackson Valley (8 miles wide and 40 miles long), beyond which, near the Idaho-Wyoming line, it enters a long canyon. In the southern part of Fremont County, Idaho, it receives Henrys Fork, below which it flows southward and westward across Idaho to a point near Homedale, near the Oregon-Idaho line, where it turns abruptly northward and forms for about 170 miles the boundary between Idaho and Oregon, and for 30 miles more that between Idaho and Washington. At Lewis ton it crosses into Washington, flows northwest, west, and southwest, and joins the Columbia near Pasco. The principal tributaries of the Snake in Oregon are Owyhee, Mal- heur, Burnt, and Powder rivers. Pine Creek, Imnaha, and Grande Ronde rivers. OWYHEE RIVER DRAINAGE BASIN. GENERAL FEATITRES. Owyhee River rises in the Humboldt National Forest in the north- central part of Nevada, flows north, then northwest across the corner of Idaho and into Oregon, where it turns abruptly and flows north- eastward to its junction with Snake River, near Nyssa, Oreg., ex- actly opposite the mouth of Boise. River in Idaho. The total length of the river is about 220 miles, and the drainage area comprises 11,100 square miles. The country drained is an exceedingly arid desert, the annual precipitation ranging from 6 to 9 inches, the larger part occurring as snowfall. Forests are entirely lacking except on the extreme head- waters, and even there they are small and the trees are those char- acteristic of arid sections. The general elevation of the river basin is about 4,000 feet, and the altitudes have but little effect on the precipitation. The streams are frequently frozen for a considerable period during the winter months, so that records for this part of the year are subject to inaccuracies. The low-water flow of this stream at the mouth is nearly aU taken by a large canal to irrigate lands lying between Owyhee and Malheur rivers. On the upper stretches of the river conditions are favorable for impounding the flood and winter flows for irrigation during the summer months, one large reservoir, the Duncan Ferry, having been surveyed by the United States Reclamation Service. COLUMBIA RIVER DRAINAGE BASIN. 67 OWYHEE RIVER AT OWYHEE, OREG. Location. — In sec. 2, T. 21 S., R. 46 E., at highway bridge half a mile above Owyhee post office and 3 miles above mouth of stream. Records presented. — March 26, 1890, to December 31, 1893; January 1, 1895, to May 15, 1897; August 27, 1903, to September 30, 1910. Drainage area. — 11,100 square miles. Gage.— Chain gage used since July 28, 1904; inclined staff previous to that date. Datum of gage unchanged since 1903 but bears no determined relation to datum of gages used prior to 1897; all readings before 1903 refer to the same datum. Channel. — Sand and gravel; somewhat shifting; riffle control 200 yards below the gage shifts only during floods. Discharge measurements. — ^Made from the bridge or by wading. Winter flow. — Stream icebound for short periods; discharge relation at times some- what affected. Diversions. — Owyhee canal diverts water about 6 miles above station; practically the entire low-water flow is used for irrigation, and the discharge measured at the station at such times is mostly seepage water. Record was kept of the flow of the canal during 1903 to 1905. (See p. 86.) Considerable water also diverted for irrigation over entire basin. Accuracy. — Records as a whole are good, but those for 1891 to 1893, during which years no measurements were made, are subject to considerable uncertainty.

Malheur River rises in the southeastern part of Grant County, flows southward to its junction with South Fork near Riverside and thence northeastward, receiving the North Fork near Juntura, Bully Creek at Vale, and Willow Creek about 4 miles below Vale, and discharges into Snake River at Ontario. Its drainage area, which includes the southeastern slope of the Blue Mountains and the eastern border of the divide that marks the boundary of the Great Basin in Oregon, is fan shaped, the outer border extending 140 miles along the mountain summits. The basin at the mouth of the river measures about 5,620 square miles, and at Riverside below South Fork 1,910 square miles. Elevations within the basin range from 5,000 feet at the head- waters to 2,000 at the mouth. The country is in general rough and broken and is largely covered with sage brush. Irrigation is re- stricted to the lower lands immediately adjoining the streams. The headwater areas are lightly forested, but elsewhere the area is timber- less and is utilized as range land for cattle and sheep. The mean annual rainfall ranges from 16 inches on the headwaters to 10 inches at Vale. During the winter months the streams are icebound for part of the time. This area offers some exceptional advantages for irrigation, for large storage sites, and ample stream flow are conjoined with enormous areas of desert lands. The United States Reclamation Service has had under consideration at different times projects which con- templated the construction of reservoirs on the headwaters of the Malheur and its principal tributaries. During the period covered by these records, the flow of the Malheur appears to have been greatest in 1904 and lowest in 1895. The earher records are not so dependable as those of later years. MALHEUR RIVER ABOVE SOUTH FORK, AT RIVERSIDE, OREG. Location.— In the SW. I sec. 22, T. 23 S., R. 37 E., 200 feet above the mouth of South Fork, half a mile above Riverside post ofl3.ce. Records presented. — January 3, 1906, to March 31, 1907; December 15, 1908, to May 25, 1910. Drainage area. — 1,110 square miles. Gage. — ^Vertical staff gage 200 feet above cable since December 15, 1908. Temporary vertical staff 400 feet above cable January 3 to 23, 1906; inclined staff 15 feet below cable January 24 to March 29, 1906, when it was washed out. Temporary gage until May 8, 1906, when chain gage was installed. Location and datum not changed after January 24, 1906. Channel. — Gravel; somewhat shifting. Discharge measurements. — Made from cable. Winter flow. — Somewhat affected by ice. Diversions. — A large area of bottom land is irrigated with flood water above the station. Accuracy. — Results fair since 1908, but only approximate for 1906 and 1907 on account of lack of measurements and uncertainties in gage readings. 90 SURFACE WATER SUPPLY OF OREGON^ 1878-1910.

Estimates : for 1910 reduced 40 per cent Jan. 1 to 23 to counteract effect of ice; Jan. 24 to Feb. 13, 1910, estimated by comparison with records below the forks; Feb. 25 interpolated because of probable effect of ice jam. Daily discharge for Mar. 3-25 not published on account of the uncertainty of the gage heights. Dis- charge Apr. 19 to May 6 estimated from a hydrograph, as comparison with records for the station below the fork indicates that gage heights are doubtful. Discharge May 26 to 31 is the difference between the values determined for the station below the forks and for the South Fork. 94 SURFACE WATER SUPPLY OF OREGON, 1878-1910.

COLUMBIA RIVER DRAINAGE BASIN. 95 MALHEUR RIVER BELOW SOUTH FORK, AT RIVERSIDE, OREG. Location. — In sec. 22, T. 23 S., R. 37 E., about half a mile above Riverside post office, at the wagon bridge about 100 yards below the-mouth of South Fork. Records available. — ^January 16, 1909, to September 30, 1910. Drainage area. — 1,910 square miles. Gage. — Standard chain; prior to June 12, 1910, staff gages referred to slightly different datums. Discharge measurements. — Made from highway bridge or by wading. Channel. — Stones and small bowlders. Control may be changed by occasional ice jams. Winter flow. — River freezes over under bridge in cold weather; flow at riffle control apparently little affected. Diversions. — Some water is diverted for irrigating ranches along the river; probably only a small proportion of the total flow is used. Accuracy. — Results fair for ordinary stages; uncertain for extreme high and low water and for periods during which discharge relation is affected by ice.

Systematic measurements of diversions from Malheur River were begun by the United States Reclamation Service in June, 1904, and continued until the end of the irrigating season of 1905. Sufficient measurements and readings on temporary gages were made to afford a basis for the estimate of total diversions given in the table on page 149. Values for any one canal are liable to considerable error, but the total is believed to be fairly reliable. Considerable water was probably diverted in October and November, 1904, though no record was kept after September 30. Discharge measurements of Vines ditch above Vale, Oreg., in 1904 and 1905. Date.

POWDER RIVER DRAINAGE BASIN. GENERAL FEATURES. Powder River, which drains the eastern slope of the Blue Moun- tains, rises in the extreme western part of Baker County, flows west, then north through Baker to the town of North Powder, where it turns abruptly to the southeast. It joins Snake River in the east central part of Baker County. The most important tributary stream is Eagle Creek, which drains the southern part of the Wallowa Mountains and enters the Powder near its mouth. The general elevation of the headwaters is 6,000 feet above sea level; that of the valley is 3,300 feet. Sumpter is 4,415 feet above sea level, and Baker 3,586 feet. The total drainage area of Powder River at the mouth is 1,660 square miles; at Baker it is 341 square miles. The headwater country is mountainous and heavily forested and the principal industry is mining and lumbering. The valley of the Powder has not been greatly developed, although a number of irri- gation ditches are in operation. Any extensive development will involve the construction of storage reservoirs, sites for which are not lacking. The mean annual rainfall at Baker is 13 inches; in the headwater region it is probably twice that amount, the greater part falling during the winter in the form of snow. The determination of stream flow in this area is rendered somewhat difficult during the winter as the streams are icebound for weeks at a time. The lowest run-off from this basin since records have been kept occurred in 1905; the highest occurred in 1904, but that of 1910 was nearly as high. POWDER RIVER AT SALISBTTRY,i GREG. Location. — In the SW. i sec. 30, T. 10 S., R. 39 E., at Salisbury station on Sumpter Valley Railroad, 10 miles above Baker. Records presented. — December 20, 1903, to September 30, 1910. Drainage area. — 230 square miles. Gage. — Vertical staff. Gage heights for 1910 refer to a datum 0.56 foot higher than that for previous years. Channel. — Gravel; somewhat shifting. Discharge measurements. — Made from wagon bridge or by wading. Winter flow. — River freezes deeply three or four months each winter. Diversions. — Most of low-water flow is diverted for irrigating small tracts along river above station. Accuracy. — Results fair. Marked diurnal fluctuation during spring, when snow is melting, decreases the accuracy. 1 Referred to in earlier reports as near Baker City, Oreg.

POWDER RIVER NEAR NORTH POWDER, OREG. Location.— In the NW. \ sec. 26, T. 6 S., R. 40 E., at proposed dam site for Thief Valley reservoir, 7 miles east of North Powder and about 8 miles southeast of Telocaset. Records presented.—March 9, 1909, to September 30, 1910 Drainage area. — 826 square miles. Gage. — Inclined and vertical staff. Channel. — Bowlders and gravel; probably permanent. Discharge measurements. — Made from cable at gage section. Winter fiLow. — River freezes; discharge relation may be affected by ice two or three months. Artificial control. — A temporary dam, constructed each year about 1 mile above the station to subirrigate adjoining lands, may cause fluctuation in stage during low- water period . Diversions. — Most of low-water flow of Powder River and tributaries diverted above station for irrigation. Accuracy. — Results good. As a rule estimates of winter flow can not be made.

Grande Ronde River, which drains the eastern slope of the Blue Mountains in Oregon and the northern slopes of the Wallowa Moun- tains (a comparatively high range that runs at right angles to the Blue Mountain Range), rises on the divide in the extreme southern part of Union County, flows in a generally northeasterly direction and unites with Snake River at Zindel, Wash., ah out 12 miles from the point at which the Snake crosses the Oregon- Washington line. The principal tributaries of the Grande Ronde are Joseph Creek, which drams the northern part of the Wallowa National Forest, the Wallowa, which rises in the southern slopes of the Wallowa Moun- tains, and Catherine Creek, which drains the western portion of the Wallowa Mountains. The drainage area of Grande Ronde River at its mouth is 3,950 square miles. Above the mouth of the Wallowa the drainage area is 1,590 square miles. The topography of this basin is in general rough, the area being almost entirely surrounded by moimtain ranges which slope grad- ually to Grande Ronde Valley, a large area of agricultural land approximately 2,700 feet above the sea level. The general elevation of the Wallowa and Blue mountains, from which the river receives its water supply, is 8,000 feet. The area drained by this river, except in the agricultural valleys, is almost entirely forested, a large part being included in the national forest reserves. The mean annual rainfall at La Grande is 19 inches, but on the headwaters of the stream it is probably 35 mches. The greater part of this precipitation occurs during the winter months as snow. The river is subject to an annual spring rise which is due to the melting of snow in the mountains, and damaging floods are frequently caused by the sudden melting of snows by chinooks. The agricultural activities have been confined largely to the pro- duction of wheat, and irrigation has not been practiced to an elabo- rate extent, although exceptionally good possibilities are afforded. Only the lower valley lands immediately contiguous to the streams have been irrigated, but there are at present under consideration a number of larger projects that involve the construction of reservoirs and the irrigation of large areas by means of long canals. Records of the flow of some of the streams in this basin have been kept since 1904. The year 1905 was a ''dry year" and all streams in the basin carried less water than during other years covered by the records. The year 1907 was a ''wet year." COLUMBIA EIVER DKAINAGE BASIN. 167 GRANDE RONDE RIVER AT HILGARD, OREG. Location. — In sec. 32, T. 2 S., R. 37 E., about half a mile east of Hilgard, at the county highway bridge just below Five Points Creek, about 8 miles above head of Grande Ronde Valley. Records presented. — November 6, 1903, to March 3, 1910. Drainage area. — 660 square miles. Gage. — Vertical staff nailed to bridge abutment. Channel. — Sand and gravel; fairly permanent. The use of the stream for log driving formerly affected the discharge relation, especially for about two months in the summer. Discharge measurements. — ^Made from bridge or by wading. Winter flow. — Severely affected by ice one to two months. Artificial control. — Practically no diversions above station; some storage developed for flooding logs. Accuracy. — Results poor on account of logs and unfavorable conditions. Discharge measurements of Grande Ronde River at Hilgard, Oreg., in 1903-1910, Date. Hydrographer. Gage height. Dis- charge.

From rating curve well defined above 40 second-feet. 1906 and 1907. From curve fairly well defined between 30 and 1,200 sccond-fcet. Estimated because of ice, as follows: Dec. 1-6, 1906; Jan. 7 to Feb. 4, 1907, 250 second-feet; Feb. 5-8, 1907, 840 second-feet. Dis- charge Mar. 8-11 and May 14 to June 30, 1906, estimated, on account of obstruction of stream by logs, from measurements. Discharge Mar. 14-22, 1907, also estimated because of log obstructions. 1908. From poorly defined rating curve. 1909. From poorly defined rating curve. Discharge obtained from open-channel rating curve Jan. 1-17 reduced 25 per cent and Dec. 19-31 reduced 15 per cent to counteract elTect of ice. Estimates for days during the winter months other than those noted were probably affected by ice to a greater or less extent. Observer made no notes concerning logs at any time after May 1, 1907, so that no corrections have been applied and records aio accordingly subject to error.

Note.— Comparison of monthlj^ mean discharges of the Grande Ronde at Hilgard with those at the Elgin station below, where conditions are more favorable, indicates that the results obtained at the Hilgard station are as a whole fairly reliable, but that those lor the early part of 1908 may be too large. GRANDE RONDE RIVER AT ELGIN, OREG. Location. — In sec. 14, T. IN., R. 39 E., at the county bridge, one-fourth mile east of the nxilroad station, at the lower end of the Grande Ronde Valley.

WALLA WALLA RIVER DRAINAGE BASIN. GENERAL FEATURES. Walla WaUa River rises on the western slope of the Blue Moiintains and flows westward into the Columbia. Its drainage basin lies imme- diately north of that of the Umatilla and is in many respects similar. Altitudes within the basin range from 5,000 feet on the headwaters to 1,000 feet near Walla Walla. The mean annual rainfall ranges from 30 inches in the upper portion to 12 in the lower portion of the area. Only the upper part of the area is forested, and that in the manner characteristic of the Blue Mountains. The lower half is given to the production of wheat without irrigation, but the lands contiguous to the streams are extensively irrigated. Chmate and soil combine to make the country wonderfully pro- ductive, and the agricultural products range from the hardier forage crops to fancy fruits. The headwaters of the stream afford favorable opportunities for water power and storage which, if developed, would more than dou- ble the value of this stream. The entire low-water flow of the river is appropriated many times for irrigation, and the only solution to a situation that has been aggravated in the extreme and promises to become even more critical as additional areas are irrigated hes in the construction of storage reservoirs. The conditions for obtaining reliable records of stream flow are not good. The river throughout is swift, and the bed is composed of gravel that changes with every freshet. On this account the records are incomplete and usually cover the period between floods. Floods on this stream are caused suddenly by chinook winds that melt the snows on the headwaters. Some of these floods have been exceedingly harmful, rendering large areas of fine farm lands worthless and caus- ing great damage to life and property. 212 SURFACE WATER SUPPLY OF OREGON, 1878-1910.

Location. — In sec. 21, T. 5 N., R. 28 E., 1^ miles above Umatilla and mouth of river; near main line of Oregon-Washington Railroad & Navigation Co., one-fourth mile below diversion point of Oregon Land & Water Co.'s canal, and one-fourth mile above headgate of Brownell ditch. Records presented. — October 21, 1903, to September 30, 1910. Records show practically the total unappropriated flow of river except the amount diverted by the Oregon Land & Water Co.'s ditch. (See p. 276.) Drainage area. — 2,130 square miles. Gage. — Inclined staff in two sections; lower section 1.2 to 3.5 feet; upper, 3.5 to 10.8 feet. Channel. — Solid rock without gravel or sand. One channel at all stages. Discharge measurements. — Made from cable or by wading. Winter flow. — Occasionally shore or floating ice; discharge relation not materially affected. Diversions. — Large part of total flow of river diverted for irrigation above station. The Umatilla project feed canal also diverts water during winter for storage in Cold Springs Reservoir. Low- water flow is mostly return water from lands under the Hermiston project and other irrigated tracts. Accuracy. — Results excellent.

Willow Creek rises in the foothills of the Blue Mountains and flows northwestward into Columbia River near Arlington. Its drainage area throughout is practically timberless and is composed of high, rolling table-lands used for the production of wheat and as range for cattle and sheep. The creek is small but is subject to excessive and sudden floods. In 1903 this stream was the scene of the disaster at Heppner, where more than one hundred lives were lost from a sudden flood lasting scarcely more than an hour. The waters of the creek are used to some extent for irrigation in the immediate valley. WILLOW CREEK NEAR ARLINGTON, OREG.

The river rises on the divide between Grant and Baker counties, Qreg., flows westward and then northward, and joins Columbia River about 28 miles above The Dalles, Its principal tributaries are North, Middle, and South forks. Its total drainage area is 7,800 square miles. The general elevation of its headwaters is about 6,000 feet above sea level; at Fossil the elevation is 1,500 feet. The headwater region of the stream is forested. Except wheat, which is grown on the rolling uplands by the ^'dry farming '^ process, no agricultural products of consequence can be raised without irrigation, and as only the immediate valleys of the streams can be readily irrigated, comparatively httle has been accompHshed. A number of projects are, however, contemplated, under which, by means of storage reservoirs and high-line canals, enormous areas of very productive table-lands would be utilized. The storage facilities are ample for this purpose. It is not likely that extensive development will be imdertaken until more detailed studies of flow have been made. The mean annual rainfall ranges from 24 inches on the headwaters to 10 inches at the mouth. The winters are cold, and the streams are frequently icebound throughout the greater part of the winter.

DESCHUTES RIVER AT BENHAM FALLS, NEAR BEND, OREG. Location.— In the NE. I sec. 16, T. 19 S., R. 11 E., about 250 yards above Benham Falls, and 14 miles above Bend; above the more important irrigation diversions from Deschutes River, and just below the dam site of the proposed Benham Falls Reservoir, Records presented. — March 30, 1909, to September 30, 1910. Records at this sta- tion aro comparable with those at West's ranch, 17 miles upstream by river, July 21, 1906, to February 20, 1909. Drainage area. — Indeterminate. Gage. — Vertical staff driven into edge of stream on right bank. Maintenance of gage datum at times somewhat uncertain. Channel. — Sandy; may shift slightly. Considerable growth of weeds along the right bank. Discharge measurements. — Made from cable. Winter flow. — Not seriously affected by ice. Diversions. — The diversion of water by some small ditches that are taken out above this station has no appreciable effect on discharge. Accuracy. — Rating curve well defined. Cooperation. — Gage heights furnished by the Central Oregon Irrigation Co. As this record has been used as a basis for all studies of the possibilities of power and irrigation development on Deschutes River between West Fork and Crooked and MetoUus rivers, it has been extended by summing the discharges of the river at Bend and of diversions between Benham Falls and Bend for all periods from January 1, 1905, to September 30, 1910, not covered by records at West's ranch.

Location. — In sec. 7, T. 18 S., R. 12 E,, at a flume section ^ mile below the point where the waters in the main diversion canal are divided between this canal and the Pilot Butte canal; about 2 miles south of Bend. Records presented. — March 11, 1905, to September 30, 1910. Gage. — Vertical staff, consisting of a painted strip of galvanized iron nailed to the inside of flume on right side. Channel. — ^A plank flume of rectangular cross section provided with batting on bottom cracks. Flume rather unstable, but rating appears not to change. Discharge measurements. — ^Made from yoke of flume at gage section. Winter flow. — Canal operated almost continuously. The flow in winter is small. The fall through the section at the gage is sufficient to maintain open channel at all times. Accuracy. — Results good.

Location. — In the SE. \ sec. 26, T. 2 N., R. 15 E., opposite Moody railroad station, 1^ miles above the bridge of the Oregon- Washington Railroad & Navigation Co., about 5 miles southwest of Biggs, and 1^ miles above mouth of river. Records presented.— July 7, 1906, to September 30, 1910; records for 1908 and 1910 somewhat fragmentary. Drainage area. — Indeterminate. Gage. — Staff in two sections — the lower inclined, the upper vertical. Discharge measurements.— Made from a cable about 450 feet above the gage. COLUMBIA KIVER DRAINAGE BASIN". 355 Diversions. — Summer discharge at this station has been progressively reduced since about 1904 or 1905 by diversions from the upper river. Some of this water returns, but the net reduction during midsummer is now probably 10 or 15 per cent. Accuracy. — Rating curve excellent, records good except for periods during which the gage-height record is fragmentary, and for which discharge has been estimated from studies of the records. Cooperation. — Gage heights furnished by M. A. Moody, The Dalles, Oreg. Discharge measurements of Deschutes River at Moody, near Biggs, Oreg., in 1906-1910. Date. Hydrographer. Gage height.

Location. — In sec. 30, T. 15 S., R. 10 E., about 4 miles above Sisters and above all diversions except McAllister's ditch. Records presented.— April 17, 1906, to September 30, 1910. Drainage area. — 63 square miles. Gage. — Vertical staff. Channel. — Gravel and rock; practically permanent; backwater from a changeable dam reaches gage and introduces changes in rating curve. Discharge measurements.— Made from a foot log just above gage or by wading. Winter flow. — Creek does not freeze over at station, but gage readings are occasionally affected by shore and anchor ice. Ice also tends to jam above dam and during extreme cold weather the effect is very marked. Diversions. — McAllister's ditch heads above this station and its flow is added to get the total. Low- water flow of stream is all diverted by several irrigation ditches below station. Accuracy. — Results good . Discharge measurements of Squaw Creek near Sisters, Oreg., in 1906-1910. Date.

Ice jam Dec. 1 and 13. The creek was frozen Jan. 10 to 24, Nov. 18, 27, and Dec. 14 to 19, 1907. Diversion dam of irrigating ditch began backing up water about May 3, 1907. The creek was frozen wholly or in part on the following dates in 1908: Jan. 31 to Feb. 7, Feb. 11 to 13, and 21 to 23, Mar. 1 to 4, Oct. 21 and 22, Nov. 14, 15, and 26 to 30, Dec. 5 to 7, 10 to 12, and 14 to 31. Diversion dam for irrigating ditch was put in in the early part of April; it was washed out Apr. 19, and replaced during May and the first week in June. Ice affected the gage heights Jan. 1 to 13 and Nov. 10 to 31, 1909. No observations Jan. 13 to Apr. 17, 1909, because the gage v/as out of plumb, due to the ice jam in January. The rise in gage heights Jan. 2 to 13, 1910, and that of Feb. 22 were evidently due to shore and anchor ice. 84792°— wsp 370—15- -26 402 SURFACE WATER SUPPLY OF OREGON, 18*78-1910.

Location.— In the NE. I sec. 5, T. 15 S., R. 17 E., at Elliott's ranch, 6 miles east of Prineville, at the dam site of a reservoir proposed in connection with the develop- ment of the Ochoco project of the United States Reclamation Service. Records presented. — November 1, 1908, to April 30, 1910. Drainage area. — 300 square miles. Gage. — Vertical staff. No change in gage datum since July 15, 1909, when the gage was lowered 0.75 foot. All gage heights corrected to later datum. Gage on ElUott ditch is vertical staff 150 feet upstream from gage in creek. Channel. — Gravel. Discharge measurements. — Made from a cable near the gage and from foot plank over ditch. Winter flow. — Discharge relation not seriously affected by ice. Diversions. — Elliott's ditch diverts water from the left bank of the creek about 1,000 feet above the gaging station. Records of the flow of the ditch are kept in order to determine the total flow past the gage. There are other diversions for irrigation farther up the creek. Accuracy. — Rating curve and records good . Discharge measurements of Ochoco Creeh near Prineville, Oreg., in 1908-1912. Date. Hydrographer. Gage height. Dis- charge. Date. Hydrographer. Gage height.

GENERAL FEATURES. Hood River is formed by the junction of East, Middle, and West forks, which drain the eastern and northern slopes of Mount Hood, and flows northeastward into Columbia River at Hood River. The stream is used for both water power and irrigation, and, being sup- plied from the glaciers on the mountain, the flow is well maintained through the summer months. The basin is heavily forested, though part of the area was burned many years ago. The mean annual precipitation at Hood River is 36 inches. The valley of the stream is noted for its production of apples, berries, and other fruit. HOOD RIVER AT WINANS, OREG. Location. — In sec. 1, T. 1 N., R. 9 E., 300 feet below the junction of the East and West forks, half a mile from Winans, 4^ miles above Tucker's bridge, and 10^ miles above Hood River. Records available. — November 17, 1905, to March 16, 1907; January 16 to Septem- ber 30, 1910. Drainage area. — 252 square miles. Gage. — Staff in two sections on right bank; lower section inclined, upper vertical. Datum of gage prior to January 16, 1910, 0.50 foot lower than present. COLUMBIA RIVER DRAINAGE BASIN. 425 Channel. — Coarse gravel and bowlders; not likely to shift. Discharge measurements. — Made from cable near gage. Diversions. — Several canals divert water for irrigating small tracts above the station, and at least one diverts around the station. Storage. — A logging splash dam on West Fork was operated during 1906 and 1907, causing irregular rate of flow. Accuracy. — Results fair.

Sandy River rises in the glaciers of Mount Hood and flows north- westward, uniting with Columbia River at Troutdale. It drains the western slope of the Cascade Mountains at their northern extremity in Oregon. COLUMBIA EIVER DRAINAGE BASIN. 433 The principal tributaries of the Sandy are Bull Run River, v/hich drains the Bull Run National Forest and furnishes the water supply for the city of Portland; Zigzag, Salmon, and Little Sandy rivers, and Camp and Still creeks. Elevations within the basin range from 647 feet above sea level at Bull Run post office to 11,225 feet at the summit of Mount Hood; Salmon post office is 1,000 feet, Bull Run Lake 3,161 feet, Govern- ment Camp 3,880 feet, and the summit of Zigzag Mountain 5,014 feet. The drainage area includes 247 square miles below the mouth of Salmon River. The drainage area of Bull Run River at the mouth is 168 square miles. The mean annual precipitation at Bull Run is 76 inches; at Gov- ernment Camp 87 inches. It is likely, however, that the figure for Government Camp is not representative because of the close proximity of the station to Mount Hood. A large part of the pre- cipitation on the headwaters falls as snow. In the foothiUs^ however, it nearly all appears as rain during the nine months from September to May. The value of the waters of this stream lies in their avail- ability for municipal water supplies and in the power that can be generated by them. Favorable sites for power development are numerous and the distance to an industrial center is not great. A large part of the basin is heavily forested, although there are many areas from which the timber was burned a good many years ago. These tracts have, however, grown up in second-growth timber and the underbrush is almost impenetrable. SANDY RIVER ABOVE SALMON RIVER, AT BRIGHTWOOD, OREG.

Measurements made in 1911 and 1912 indicate that the curve used gives results 5 to 10 per cent too large between gage heights 10 and 20 feet and somewhat too small above 25 feet, but the effect on any yearly or monthly mean is slight. Discharge estimates for 1878 to 1880 are subject to much uncertainty, as the permanence of gage and channel since that time is questionable.

I sec. 11, T. 10 S., R. 3 W., at the Southern Pacific Railroad bridge in Jefferson, about 2J miles below junction of North and South forks and about 9 miles above mouth. Records available. — October 8, 1905, to July 1, 1906; October 1, 1907, to September 30, 1910. Drainage area. — 1,890 square miles. Gage. — Vertical staff on center pier of railrod bridge; some of the high- water readings have been made from a vertical staff on right bank. Channel. — Rock and coarse gravel; practically permanent. Readings in 1905 and 1906 '^were affected by backwater from logs that lodged in the river below. Discharge measurements. — ^Made from Southern Pacific Railroad bridge or from the highway bridge just below it. Diversions. — The Albany power canal diverts water from South Fork of Santiam River near Lebanon; the Salem power canal, from North Fork of Santiam River near Stayton; and water is diverted from North Fork for irrigation near West Stayton. No measurements made of these diversions until 1911. The discharges presented herewith therefore represent unappropriated flow. Accuracy. — Results good for 1907 to 1910. Estimates of discharge withheld for 1905 and 1906 on account of poor data. Cooperation. — Gage readings furnished by S. A. Pease, of Jefferson Mill Co., and the United States Weather Bureau.

Discharge over the 23-foot weir computed from a rating curve based on one discharge measurement and the weir formula, allowing for velocity of approach and assuming leakage of 10 second-feet through the weir; curve well defined below 100 second-feet and fairly well defined for higher stages.

The North Umpqua rises in Mardu Lake near the summit of the Cascade Range at an elevation of over 6,000 feet and pursues a westerly course. The South Umpqua is also formed by two forks — ■ the northern rising on old Bailey Mountain, about 4 miles south of Diamond Lake, and the southern on the northern slope of Abbot Butte, and the united waters flow westward and northward. From the junction of its principal forks, the Umpqua takes a tortuous but in general northerly course to Elkton, beyond which its course is more nearly westward until it debouches into the Pacific at Winchester Bay in the northwestern part of Douglas County. Its total drainage area comprises about 4,000 square miles. At Scottsburg, just above tide water, the area measures 3,070 square miles. The North Ump- qua drains 1,080 and the South Umpqua 1,990 square miles. The important tributaries of the Umpqua are Smiths River, which drains the low mountainous area near the coast; Elk Creek, draining the divide between the Umpqua and Willamette basins; and Cow Creek, which drains the divide between the Rogue River and Umpqua basins. The country is rough and mountainous, and the streams flow in comparatively narrow valleys bordered by narrow stretches of agri- cultural land. The general elevation of the headwaters is 6,000 feet, with a few snow-capped peaks 8,000 to 10,000 feet high. The ele- vation at Roseburg is 485 feet above sea level. The North Umpqua faUs over 3,600 feet in the 75 miles from Diamond Lake to Roseburg by the river channel. The lower portion of the Umpqua has com- paratively little fall, as is evidenced by the very winding character of the stream. The region is one of the most densely forested m the United States, and probably 80 per cent of the drainage area can be classed as heavily forested. About one-fourth of the forest area is included in the national forests; the rest is owned by corporations and indi- viduals. The mean annual rainfaU at Roseburg is 30 inches; at Drain, near the divide between the Willamette and Umpqua drainages, it is 48 inches. At the mouth of the stream there probably is as much as 60 inches per annum, while at the headwaters the precipitation is 100 inches or more. Except on the headwaters all of this falls as rain during the nine months of the year from September to May. 600 SURFACE WATER SUPPLY OF OREGON, 1878-1910. Little irrigation has been practiced in the Umpqua Valley, although a few small ditches may be found on the smaller creeks of the North and South forks. The agricultural products consist of grain and fruits. For the production of apples, prunes, and similar fruits, the climate and soil are especially well adapted. Although the possibili- ties for water-power development in this area are almost phenomenal, there are no important plants. There is a remarkable difference between the run-off of the North and South forks of the Umpqua which would have been very diffi- cult to detect except through actual records of stream flow. The annual run-off of the North Fork is 4 second-feet per square mile, whereas that of the South Fork is 1.6 second-feet per square mile. Since records have been kept highest run-off values were shown in 1907. It is probable that 1905 was a year of low run-off, although the records do not cover that period.

From rating curves well defined between 1,200 and 10,000 second-feet, and fairly well defined to 20,000 second-feet. Discharge estimated Nov. 3-18 and Dec. 17, 1905. Discharges in August, Septem- ber, and October, 1906, and July to October, 1907, probably somewhat large as water was below the zero of the gage and the observer reported the reading as zero. 1009. From curve well defined between 1,100 and 10,000 second-feet. Discharge Aug. 8-31, Sept. 2-26, and Oct. 10-17, estimated from comparison of hydrographs for other stations in Umpqua River basin- 1910. From curve well defined between 900 and 10,000 second-feet. Discharge July 8 to Sept. 2, estimated from comparison of hydrographs for discharge of North Umpqua River at Winchester. Measurements made in 1912 indicate that the high-water extension of the curves may be somewhat too large. Monthly discharge of Umpqua River near ElJcton, Oreg.,for 1905-1910. Month.

ROGUE RIVER DRAINAGE BASIN. GENERAL FEATURES. Rogue River drains the southwestern corner of the State of Oregon, its basin extending from the extreme western part of KLamath County across Jackson and Josephine counties, and including the northern half of Curry County. On its north are the Rogue River Mountains, on the east are the Cascades, and in the southern part of the area is a spur of the Siskiyou Mountains. In all the basin comprises 5,080 square miles. The river is formed by three principal forks — the North, Middle, and South — which rise among the peaks of the Cascade Range and imite near Prospect, in Jackson County. From this point the Rogue winds in a general westerly direction to the ocean, which it enters near the town of Gold Beach, in Curry County. In the lower half of its course the stream hugs closely the base of the Rogue River Range, and its principal tributaries are from the south, as is shown by the following table: EOGUE EIVEK DRAINAGE BASIN. 625 Principal tributaries of Rogue River. From the north and west. North Fork. Elk Creek. Stewart Creek. Evans Creek. Leland Creek. From the east and south. Middle Fork. South Fork. Big Butte Creek (drainage area, 268 square miles). Little Butte Creek (drainage area, 361 square miles). Bear Creek (Stewart Creek) (drainage area, 380 square miles). Applegate River (drainage area, 606 square miles). Illinois River. The North Fork, or main stream, derives its water from springs, possibly supplied from Crater Lake, which lies to the east in the center of Crater Lake National Park, at an elevation of 6,240 feet above sea level. This lake occupies the crater of an ancient volcanic mountain to which the name Mount Mazama has been applied. The lake has no visible outlet ^ nor any other reaching the surface within a few miles. The walls inclosing the lake are made up of alternating sheets of lava, dipping away from the lake practically in all directions, and are so porous as to afford an easy passage for much water. Springs are abundant and remarkable in size. Little and Big Butte creeks drafn the southern portion of the Cascade Forest Reserve. Bear Creek, formerly called Stewart Creek, drains the famous fruit section of Rogue River Valley; Applegate River drains the Siskiyou Mountains; and Illinois River the territory to the south of the main stream near the coast. The drainage area is in general mountainous, elevations ranging from sea level at Gold Beach to 9,760 feet at the summit of Mount McLoughlin (formerly known as Motmt Pitt) — a snow-capped peak dividing the drainage of Big Butte and Little Butte creeks. The gen- eral elevation of the mountain range at the headwaters of the Rogue is 6,000 feet. Prospect is 3,000 feet, Ashland is 1,938 feet, and Grants Pass 956 feet above sea level. The area is almost completely timbered, but the stand is not so heavy as on the area to the north drained by Umpqua River, as the precipitation is lighter. The mean annual rainfall at Gold Beach is 86 inches, at Grants Pass 33, at Ashland 27, on the headwaters of Illinois River 70, and at Crater Lake 100 inches. At the headwaters of the stream the greater part of the precipitation is rain during the winter months. 1 Diller, J. S., Geology of Crater Lake National Park: U. S. Geol. Survey Prof. Paper 3, p. 60, 1902. 84792°— wsp 370—15 40 626 SURFACE WATER SUPPLY OF OREGON, 1878-1910. As is usual in regions where the precipitation is sufficient for the production of crops without irrigation, development along this line is inconsiderable. The ditch of the Rogue River Valley Canal Co., which diverts water from Little Butte Creek, is the largest in opera- tion. A number of little ditches are used to irrigate the narrow val- ley lands contiguous to the small streams. In this manner Ashland and Wagner creeks and Applegate River are largely appropriated for irrigation. It is realized, however, that the agricultural resources of this section of the country wiU not be utilized in the most economic maimer until irrigation is practiced extensively. The valley lands in the vicinity of Grants Pass along Bear Creek are particularly adapted to fruit culture, and the Rogue River VaUey has become justly famous for the excellent quality of apples, pears, and other fruits raised there. The streams of this area, like others draining the Cascade Range afford wonderful possibilities for water-povfer development. At present the only important plants are those of the California- Oregon Power Co. at Gold Ray and at Prospect. Stream measurements in this basin were begun in August, 1905. The highest run-off values are shown by the records for 1907. It is probable that the lowest values would have been found in 1905 if records for that year had been complete.

GENERAL FEATTJilES. Klamath River drains a territory lying east of the Cascade Range in south-central Oregon and south of the Siskiyou Mountains in Cali- fornia. The river rises in Upper Klamath Lake, flows generally southward, and reaches the Pacific Ocean at Requa on the coast of northern California. Only that part of the basin lying in Oregon has been studied in detail. The drainage from this portion of the area is collected in large lakes whose margins are wide shallow marsh lands covered with tules and aquatic plants. From Upper Klamath Lake, which stands 4,141 feet above sea level, flows Link River, a stream 1 J miles long, discharging into Lake Ewauna at an elevation of 4,080 feet. Klamath Falls, the principal city of this section, is located on Link River. From Lake Ewauna to the town of Keno, Klamath River flows through a flat, marshy country a distance of 20 miles. About 5 miles above Keno the river is connected with Lower Klamath Lake by a channel known as Klamath Straits. During high stages water flows from Klamath River into Lower Klamath Lake, and during low water the direction of the flow is reversed. About half a mile below Keno the river breaks over a rocky ledge, and here begins its precipitous fall of 100 to 200 feet per mile to its mouth. The drainage area above Keno, exclusive of Lower Klamath Lake, is 3,150 square miles. The streams draining into Upper Klamath Lake head about 6,000 feet above sea level. The elevation of Kla- math Falls is 4,100 feet. 656 SURFACE WATER SUPPLY OF OREGON, 1878-1910. The principal tributaries of Klamath Kiver are Williamson River, which drains the northern part of the Klamath Indian Reservation, Sprague River, which is tributary to Williamson River and drains the southwestern rim of the Great Basin divide in Oregon, and Anna River, which heads in a large spring supposed to be fed by the waters of Crater Lake. Lost River, although not a tributary of the Klamath, is usually considered with it, as the two are connected by a slough. Water formerly flowed either way, the direction depending on the heights of the streams, but the flow is now stopped by an artificial dike. The mean annual rainfall at Klamath Falls, about 12 inches, is fairly representative for this section of the drainage area. A large part of this precipitation occurs as snow. As nearly all the streams are spring fed and therefore rarely freeze, records of stream flow are little affected by ice. Irrigation is practiced extensively in the upper part of the area, although dry farming has been fairly successful. The agricultural products consist chiefly of forage crops, the country being well adapted to stock raising. Grains, alfalfa, and the hardier vegetables and fruits are grown with some success, but the climate is too rigorous for the intensive agriculture that is possible at lower altitudes. Within the period covered by stream-flow records the year of lowest run-off was 1905 and the highest 1907. Gage records have been obtained since 1904 on Upper Klamath Lake, Lower Klamath Lake, and Tule Lake, and during 1907 and 1908 the three gages in Klamath River between Upper and Lower Klamath lakes were read. Since 1905 records of evaporation have been kept at Keno. WILLIAMSON RIVER NEAR KLAMATH AGENCY, OREG. Location. — In the NW. | sec. 7, T. 32 S., R. 9 E., at lower extremity of Klamath Marsh, at point locally known as Rocky Ford, 13 miles northeast of Klamath Agency. Records presented. — March 25, 1908, to June 26, 1910. Drainage area. — 1,160 square miles. Gage. — March 25 to October 17, 1908, vertical staff 1,000 feet above the cable. Octo- ber 17, 1908, Bristol self-recording gage was installed at same site; records obtained until December 31, 1908. May 30, 1909, gage moved to location of cable and set to read the same but at a different datum. New datum of gage, 4,622.19 feet above sea level. November 10, 1909, auxiliary staff gage installed below mouth of Spring Creek, about 11 miles below the station. Bristol self-recording gage used from April 15 to June 26, 1910. Channel. — Gravel and sand; considerable growth of aquatic plants. Discharge measurements. — Made from cable. Winter flow. — Somewhat affected by ice. Accuracy. — Estimates fair.

UPPER KLAMATH LAKE NEAR KLAMATH FALLS, OREG. Location. — In sec. 30, T. 38 S., R. 9 E., at the outlet of Upper Klamath Lake, about 2 miles northwest of Klamath Falls. Records presented. — ^May 28 to October 22, 1904; January 7, 1906, to September 30, 1910. Gage. — Friez automatic register since February 16, 1906; vertical staff prior to that date. Zero of gage 4,136.13 feet above sea level. During 1904, vertical staff on Pelican Bay; zero 4,137.93 feet above sea level. Accuracy. — Gage heights are very much affected by the wind. The water is lowered as much as 6 inches near the outlet when the wind blows from the south and is raised as much above its normal level when the wind is in the opposite direction. There is a periodic oscillation when the wind blows for any length of time. Cooperation. — Station maintained by United States Reclamation Service since May, 1909.

Location. — In sec. 32, T. 38 S., R. 9 E., at the county bridge over Link River at Klamath Falls, 1^ miles below outlet of Upper Klamath Lake, and immediately at head of Lake Ewauna. Records presented. — May 15, 1904, to September 30, 1910. Drainage area. — 3,110 square miles. Gage. — Chain gage at bridge. Since June 6, 1908, a Friez automatic gage has also been maintained in the rapids above the bridge. Channel. — Permanent at both gages; water swift at upper gage, sluggish at lower. Discharge measurements. — Made at the county bridge. Winter flow. — ^Gage height seldom if ever affected by ice. Diversions.^ — Since about September 1, 1908, water has been diverted around the Friez gage in the Keno canal on west side of river. This water, after being used in the Moore Bros, power plant, has been returned to the river between the Friez gage and the bridge. Measurements and records of the United States Reclamation Service have made possible a fairly accurate estimate of the amount of this diver- sion. It has been measured from time to time, but has been held fairly constant between dates of change. Some water has been wasted over a spillway just above the power flume, probably not more han 5 second-fe3t on the average. Water has also been diverted in the main canal of the Klamath project on the east side of the river, but only a small quantity prior to the irrigating season of 1911. Accuracy. — The records prior to June 6, 1908, especially the individual daily records, are not reliable. For longer periods — a month or more — the determination of mean flow can probably be accepted as not greatly in error. This condition is accounted for by the effect of wind on the discharge at this station. Until May 8, 1908, the gage was situated at the bridge at the upper end of Lake Ewauna. At the outlet of Upper Klamath Lake the river breaks over a rather shallow ledge, A strong wind upstream blows the water back from this outlet and at the same KLAMATH RIVER DRAINAGE BASIN. 665 time increases the height of water on the gage by backing the water in Lake Ewauna, causing diminished flow with increased gage height. So great is this effect of the wind that the river has been known to go entirely dry for a few hours at a time. When the wind is downstream the flow of Link River is greatly inreased, but the surface of Lake Ewauna is so large that the increase in flow is not shown by the gage heights. In the long run these wind effects are no doubt compensating, but little dependence can be placed in the published daily records prior to March 7, 1907. On this date an anemometer was installed on the bridge and a ship's taffrail log was trailed in the water under the bridge. It was hoped that the daily reading from this log would afford some indication of the velocities with the anemometer records. Although the records obtained by this device were much more reliable during 1907 than previously, even they were not all that could be desired. It became evident that owing to the sudden changes of the wind complete data could not be obtained without automatic recording devices on both the log and anemometer. The method was effective, however, in reducing the probable error of the estimates from about 15 per cent to within less than 5 per cent. On June 6, 1908, a Friez gage was installed in the rapids, where it could be affected only by change in flow, measurements being made at the bridge as formerly. From that date until some time during the summer of 1909 the records given by the Friez gage were reliable, but since that time, on account of diversions, damage resulting from logs striking the gage well, back- water from logs, and failure to keep the gage always at proper datum, the records are subject to some uncertainty; they are still, however, more reliable than records that can be obtained from gage heights at the bridge. Cooperation. — Since May, 1909, station has been maintained by the United States Reclamation Service, the Survey working up and publishing the data.

KLAMATH RIVER AT KENO, OREG. Location. — In sec. 31, T. 39 S., R. 8 E., at county bridge at Keno. Records presented. — May 31, 1904, to September 30, 1910. Drainage area. — 3,150 square miles (excluding Lower Klamath Lake drainage area). Gage. — Vertical staff nailed to bridge; datum unchanged. Channel. — Sand and clay; fairly permanent. Aquatic plants accumulate during low water. Immediately below station river breaks over a rocky ledge, falling about 200 feet to the mile. Discharge measurements. — Made from cable about 1,000 feet below gage. Winter flow. — River usually freezes over in winter, but as the water is deep and the ice never very thick the discharge relation is not seriously affected. Accuracy. — During low water the accuracy of the record is somewhat affected by the growth of weeds. Low-water measurements are also somewhat uncertain on account of the extremely low velocities. Wind also has an effect at times. No measurements made since 1909; later estimates somewhat uncertain. Cooperation. — Station maintained by the United States Reclamation Service since May, 1909.

Location. — In sec. 14, T. 39 S., R. 10 E., at highway bridge at Olene. Records presented.— May 24 to July 30, 1904; May 19, 1907, to September 30, 1910. Drainage area. — 1,290 square miles. Gage. — Vertical staff; also hook gage used since April 23, 1909. Channel. — A permanent rocky riffle 200 feet below the gage controls the gage heights. Discharge measurements. — Made from highway bridge except during extreme low water, when better measurements can be made by wading at the riffle. Winter flow. — Gage heights not seriously affected by ice. Diversions. — At a point 5 miles below this station a dam has been built to divert the water of Lost River through a canal into Klamath River and thus reclaim lands bordering on Tule Lake. Accuracy, — Conditions favorable for good results. Cooperation. — Station maintained by the United States Reclamation Service since May, 1909, but the records have been worked up by the United States Geological Survey.

TTJLE LAKE NEAR MERE-ILL, OREG. Location. — In sec. 8, T. 41 S., R. 11 E., at J. F. Adams's ranch, near mouth of Lost River, 3 miles east of Merrill. Records presented.— May 17, 1904, to September 30, 1910. Gage.^ — Vertical staff fastened to post driven in lake bed. Datum of gage at present 0.83 foot higher than when checked in October, 1904. This change was verified in June, 1907, and again in November, 1907. As graph of gage heights has failed to reveal any critical points that would account for a sudden change, it is likely that the gage was raised by the ice a little at a time during the winters of 1905-6 and 1906-7. On account of this error the gage heights prior to May, 1907, should not be used for any refined studies.

Location. — In sec. 7, T. 40 S., R. 14 E., at the highway bridge 3 miles south of Lorella and 1 mile east of the Swingle ranch in Langell Valley, since April 1, 1909; August 10, 1904, to December, 1908, in sec. 12, T. 39 S., R. 13 E., 9 miles northeast of Lorella, at the lower end of Horsefly Valley. Records presented. — August 10, 1904, to September 30, 1910. Drainage area. — 270 square miles; at old station 220 square miles. Gage. — Friez automatic register. No change in datum since April 1, 1909. Channel. — Rocky and fairly permanent. Discharge measurements. — At medium and high stages made from highway bridge; low- water measurements made by wading at riffle. Diversions. — A small irrigating flume carrying about 1 second-foot diverts just above present station. Winter flow. — River freezes over completely; winter records not reliable. As the total annual flow, however, is the important feature, a large error during such periods is admissible without affecting the desired results. Accuracy. — Results fair; records somewhat fragmentary until Friez gage was installed January 30, 1910, but discharge has been estimated for all periods for which gage heights were missing. Cooperation. — Station maintained by United States Reclamation Service since May, 1909^ records worked up by engineers of United States Geological Survey.

GOOSE LAKE DRAINAGE BASIN. GENERAL FEATURES. Goose Lake is situated in the northern part of Modoc County, Cal., and southern part of Lake County, Oreg., about two-thirds of the lake being in Cahfornia, but by far the greater part of the valley being in Oregon. The lake lies 4,800 feet above sea level, is about 28 miles long, 10 miles in maximum width, and not more than 20 feet in maximum depth. It is fed by 16 streams in California, draining an aggregate of about 250 square miles, and 6 streams in Oregon. It probably receives also a large supply of water from subsurface springs. The annual rainfall on the open surface of the lake has been estimated at 14 inches. It is said that in the early sixties an emigrant trail crossed the valley of the creek at a place where the water is now several feet deep, but a few years later the lake rose so as to extend several miles farther north than it now extends, and for a short time in 1869 it overflowed southward to the north fork of Pit River. In 1881 it is reported to have overflowed to Pit River for more than 2 hours during a severe storm from the north. Along the northern edge of the lake are considerable areas of marsh hay lands, but farther north the vaUey is an unreclaimed sagebrush desert except for a few homesteads. The lower end of the lake is bordered by lava beds through which some water may be lost by percolation. The water of Goose Lake is slightly alkaline, though considerably less so than that of other lakes in the vicinity. Drews Creek, Cottonwood Creek, and Thomas Creek, the principal streams flowing into the basin in Oregon, drain the southeast slope of a high timbered ridge near the southern corner of Lake County. The water of Drews Creek is utilized by the Goose Lake VaUey Irri- gation Co. for the reclamation of 40,000 acres of land in the Goose 728 SURFACE WATER SUPPLY OF OREGON, 1878-1910. Lake Valley. A storage reservoir of 60,000 acre-feet capacity has been constructed on Drews Creek about 5 miles above the mouth of the river canyon. From this reservoir an irrigation ditch has been constructed which carries water along the borders of the valley both north and south of Drews Creek. A northern branch wastes into Thomas Creek near the city of Lakeview. There is also a good storage site on Cotton- wood Creek. The How of Cottonwood Creek is well maintained throughout the year, but Drews Creek is more flashy. COTTONWOOD CREEK NEAR LAKEVIEW, OREG. Location. — In sec. 29, T. 38 S., R. 19 E., at a dam site 10 miles northwest of Lakeview. Records presented.— November 22, 1908, to September 30, 1910. Drainage area. — 30 square miles. Gage. — Inclined staff; gage just above a weir at dam site used November 22, 1908, to January 18, 1909. Channel. — Clean gravel; fairly permanent; 10-foot weir November 22, 1908, to January 16, 1909; 15-foot weir January 17 and 18, 1909. Discharge measurements. — Made from a footbridge 40 feet below present gage; low-stage measurements made by wading near gage. Winter flow. — Gage heights at times affected by ice, but winter flow is so small that no serious errors are introduced into the estimates. Diversions. — ^None above station. Accuracy. — Conditions excellent and results fairly reliable except when large diurnal fluctuations are caused by melting snow during the early spring. Cooperation. — Station maintained in cooperation with Goose Lake Valley Irrigation Co., which furnishes gage-height record. Discharge measurements of Cottonwood Creek near Laheview Oreg., in 1909-10.

In Oregon, as in other parts of the Great Easin, the surface waters collect in natural depressions in the ground. Where the flow into these depressions is sufficient perennial lakes are formed of such extent that evaporation balances the inflow; where the surface flow is insuffi- cient, intermittent lakes or playas are formed. The principal lakes in the Great Basin in Oregon are Warner, Abert, Summer, Silver, Malheur, and Harney. Except Silver Lake in Lake County and the three southerly of the Warner lakes, all these lakes are more or less alkaline. 736 SURFACE WATER SUPPLY OF OREGON, 1878-1910. WARNER LAKE DRAINAGE BASIN. GENERAL FEATURES. Warner Lake includes a chain of lakes and marshes extending in a general north-south direction between two high escarpments in the southeastern part of Lake County. The waters of these lakes flow from south to north and the lakes in the southern end of the valley are therefore fresh whereas those at the northern end are alkaline. The larger lakes in the area, from north to south, are Crump Lake, Hart Lake, Flagstaff Lake, and Bluejoint Lake. The general eleva- tion of the water surface is about 4,460 feet. Protected by the high ridges that border it on both sides, Warner valley has reached a fairly high stage of agricultural development. At the base of the hills bordering the western shores of Hart and Crump lakes are a number of prosperous ranches whose products include fruit, grains, and nearly all agricultural crops. The principal streams in this basin are Twentymile Creek flowing from the south; Deep Creek, formerly caUed Warner Creek, flowing from the west; and Honey Creek, flowing from the west. These streams drain a high, practically timberless ridge, but the flow of the streams is well maintained during the summer months. Deep Creek is the most important of these streams and Honey Creek is the next, though Twentymile Creek furnishes about the same amount of water as Honey Creek. All three are used more or less for irrigation, and any additional development wiU require construction of storage res- ervoirs on their headwaters. Around the west side and north end of the valley is a large area of agricultural land which is now growing sagebrush. The Warner Lake Irrigation Co. has under contemplation the irrigation of these lands by water stored on the headwaters of Warner and Honey creeks. The project is to be developed under the provision of the Carey Act. TWENTYMILE CREEK NEAR WARNER LAKE, OREG. Location. — In sec. 24, T. 40 S., R. 23 E., about one-fourth mile above the bridge at the mouth of the canyon, about 2 miles south of Warner Lake post office. Below- all tributaries. Records presented. — March 1 to September 30, 1910. Drainage area. — About 169 square miles, including area tributary to Cowhead Lake, which overflows only occasionally. Gage. — Vertical staff in two sections about one-fourth mile above the bridge and above a fall in the stream. A gage at the bridge was read during March and April, but as the discharge relation was affected by backwater from a dam below, it was removed to the present site. So far as possible, however, all gage readings re- ferred to the present gage have been reduced to the same datum. Channel. — Bowlders and gravel; probably shifts slightly. JDischarge measurements. — Made from highway bridge or by wading. WAENER LAKE DRAINAGE BASIN. 737 Winter flow. — Creek freezes over at gage but practically always remains open at rock control below. Diversions. — Only a small amount of water diverted above the station. Artificial control. — Backwater from a diversion dam below the bridge may reach the gage, but did not in 1910. Accuracy. — Gage heights show marked diurnal fluctuations at times during the spring, thus causing considerable inaccuracy in the records.

Readings on bridge gage after Apr. 19 discarded, as they indicate backwater from the diversion dam below. Probably no ice at this station during period covered by records. Readings for Mar. 1 and 2 may have been made in the afternoon and are probably higher than the true daily mean. 84792°— wsp 370—15- -47 738 SURFACE WATER SUPPLY OF OREGON, 1878-1910.

Determinations for the early part of March, especially the first two days, are liable to considerable error, resulting from reading the gage but once daily during a time when there was considerable diurnal fluctu- ation.

Location.— In the SE. i NW. i sec. 21, T. 39 S., R. 24 E., about one-eighth mile above the wagon bridge crossing the creek at Adel; below all tributaries. Records available.— May 11, 1909, to September 30, 1910. Drainage area. — About 260 square miles. Gage.— Vertical staff in two sections about 500 feet above the bridge and above a series of rapids; datum unchanged. A second gage installed at the bridge Feb- ruary 28, 1910, by the Warner Lake Irrigation Co. was at times affected by back- water from temporary dam below. Charmel.— Probably permanent; bed of stream composed of gravel and stone. Discliarge measurements. — Made from the wagon bridge or by wading. Diversions. — Several small ditches divert water for irrigation near the headwaters of the stream and five ditches take out within 6 or 8 miles above the station and carry water around it to irrigate several hundred acres of land; 2,000 or 3,000 acres of land are watered by natural flooding near Big Valley and Crane Lake, but much of the water is probably returned to the stream. The combined capacity of the five ditches above mentioned is about 30 second-feet. Measure- ments of the combined discharge showed 25 second-feet of water in June, 1910; 20 second-feet in April, 1911; 18 second-feet in July, 1911. Below the bridge the grade of the stream is very flat and water is diverted into the M. C. ditch by means of a temporary dam which is repaired at the beginning of each irrigation season. Winter flow. — Discharge relation may be slightly affected by ice during periods of extreme cold weather and occasionally by backwater from ice jams. Control usually remains open. Accuracy. — Determination of mean gage height is rendered rather difiicult during the spring by diurnal fluctuations, which, however, are not so marked as on Twenty-mile and Honey creeks.

Daily discharge, in second-feet, of Deep Creek at Adel, Oreg.,for 1909-1910 — Continued. Note.— Daily discharge, except as noted, based on readings of the upper gage as published. Discharge May 11 to Nov. 20, 1909, determined from a rating curve fairly well defined above 50 second-feet; curve is based on one measurement in May and the form of the curve for the period following, but it gives results consistent with the daily discharge for low water of 1910. Discharge from Nov. 21, 1909, to Sept 30, 19i0, determined from a ratuig curve well defined between 10 and 1,500 second-feet. Special methods used as follows: Jan. 2-9, discharge interpolated because of ice; Jan. 23, estimated, because of ice jam, at about one-half of open-channel discharge; Jan. 24 to Feb. 7 estimated, assuming that creek fell rather rapidly alter the high water; Feb. 8-13, estimate reduced on account of ice; Mar. 1-10, discharge taken from a hydrograph drawn by plotting as coordinates with time the discharge correspond- ing to gage readings on the upper gage and the measurements made by engineers of the Warner Lake Irri- gation Co.; probably represents the daily mean fairly well; Mar. 11-31, mean discharge determined from the two sets of gage readings on upper and bridge gage.

WAENER LAKE DEAINAGE BASIN. 743 HONEY CREEK NEAR PLUSH, OREG. Location.— In the SW. i sec. 20, T. 36 S., R. 24 E., half a mile above the mouth of the canyon, 1^ miles northwest of Plush, and 1 mile above the wagon bridge near Plush; below all tributaries. Records presented. — May 13, 1909, to September 30, 1910, Drainage area. — ^About 185 square miles. Gag-es. — The first gage was a vertical staff fastened to the wagon bridge, but as gage heights were affected by backwater from a temporary diversion dam below the station, a vertical staff in two sections was installed by the Warner Lake Irrigation Co., February 24, 1910, half a mile above the mouth of the canyon and 1 mile above the bridge. Channel. — Bed composed of gravel; shifts slightly. Discharge measurements. — ^At the original site made from the bridge; now made from cable near the gage or by wading. Winter flow. — Considerably affected by ice. Diversions. — Records at this point show the total run-off from the basin above the station except for a small amount of water diverted near the head of the stream and used to irrigate a few hundred acres. Accuracy. — Records fairly reliable, although some inacuracy is caused by diurnal fluctuations of the stream. Cooperation. — Station maintained in cooperation with the Warner Lake Irrigation Co.

Ice conditions probably existed throughout the month. All gage heights for 1909 refer to gage at bridge. Bridge gage read Jan. 1 to Apr. 16, 1910, gage in poor condition and flow affected by ice part of the time; gage height, can not be used except for period Jan. 18 to 23. Gage at the mouth of the canyon read from Feb. 24. Gage heights Feb. 24 to Mar. 5 taken from a hydro- graph plotted from both the direct readings on the upper gage and the readings on the lower gage reduced to corresponding heights on the upper by means of a curve of relation. Gage heights beginning Mar. 6 repre- sent one reading daily; no observations July 17 to Sept. 30. Gage heights for portions of November and December somewhat questionable. Probably no ice at the upper gage during the period of records. WARNER LAKE DRAINAGE BASIN. 745 Dailij discharge, in second-feet, of Honey Creek near Plush, Oreg.,for 1910. Day. Jan. Feb. Mar. Apr.

Daily discharge Feb. 24 to Mar. 5 — a period of great diurnal fluctuation— determined by applying the rating table to gage heights taken at 3-hour intervals from a hydrograph and using the mean of the 8 de- terminations of discharge as the discharge for the day. This method gives results considerably larger than those obtained by applying the rating table to the mean of the gage heights. Dally discharge for high-water period in January determined by assummg a discharge of 30 second- feet for the gage reading of Jan. 19 on the lower gage, and extending a curve through this point parallel to the curve derived from the relation of the gages in February and March; values Jan. 22 and 23 reduced arbitrarily for assumed effect of ice jam; discharge was further assumed to have fallen rather rapidly.

GENERAL FEATURES. Abert Lake is a strongly alkaline body of water lying near the cen- tral part of Lake County. It has a surface area of 60 square miles at an elevation of about 4,240 feet. The waters are largely supplied from Chewaucan River and Crooked Creek. Chewaucan River rises on the high divide in the southern part of Lake County and flows northward into Chewaucan marsh, through which it meanders in a southeasterly direction and flows into Abert Lake at its southern extremity. The principal agricultural development in the basin consists of the hay lands in the Chewaucan marsh and the area of irrigated lands bordering the marsh on the south and along Chewaucan River in the vicinity of Paisley. 748 SURFACE WATER SUPPLY OF OREGON, 1878-1910. CHEWAUCAN RIVER AT PAISLEY, GREG. Location.— In the SE. ^ sec. 23, T. 33 S., R. 18 E., half a mile above the town of Paisley. Records presented. — ^January 4, 1905, to December 13, 1907; January 17, 1909, to September 30, 1910. Drainage area. — 272 square miles. Gage. — Vertical staff. Channel. — Probably permanent; bed composed of clean gravel; banks subject to overflow at stages above gage height 8 feet. Discharge measurements. — Made from cable-60 feet below gage or by wading. Winter j3.ow. — Affected by ice. Diversions. — The station is above all diversions except George Conn's irrigation ditch, which heads about 2 J miles above the gage on the left bank and diverts water around the station. Conn's mill ditch diverts water from the left bank about 250 feet below the gage, where a low timber dam has been constructed. The current is fairly swift between the gage and the dam and practically no back- water was noticeable prior to 1910. During 1910 there was probably a little back- water. The Brattain ditch diverts water about 300 feet below the gage on the right bank; it follows the foothills for many miles do^vn the river and supplies water for use in irrigating land immediately around Paisley and large areas of hay land in Chewaucan Marsh. Storage. — It has been proposed to store the water of Chewaucan River at a point 20 miles upstream from Paisley to provide for the reclamation of a tract of 12,000 acres northeast of Paisley under the terms of the Carey Act. The development of this project, however, has been hindered by water-right claims of the owners of hay lands in Chewaucan Marsh. These lands have been flooded during the spring and winter to a depth of several feet and, as all the water is claimed for this flooding, development work can not proceed until water rights have been adjudicated.

Summer Lake is a strongly alkaline body of water with a surface area of about 70 square miles, at an elevation of about 4,140 feet. The water is supplied largely from Ana River, a stream 7 miles long, which heads in five large springs on the northern border of the valley. These springs supply a continuous flow of about 145 second-feet. The water has a nearly constant temperature of 65°. The agricultural development in this basin is limited to a narrow strip lying at the foot of a high escarpment along the western shore of Summer Lake. This narrow strip is the most favored section in central Oregon and in it intensive agriculture has been practiced since 1848. The escarpment is effective protection against the cold winds from the west and north, which in passing over make an eddy drawing the warm air of the lake over the lands and serving to equalize the temperature. The region has long been famous for its fruit. Apples, pears, peaches, cherries, and berries of all kinds are grown in abundance and crop failures are practically unknown. Along the eastern shore of the lake and extending eastward into the wide valley adjoining Chewaucan marsh is a large area of agri- cultural land, a portion of which could undoubtedly be watered from Ana River and another portion from Chewaucan River. Projects looking to the irrigation of these lands have been under consideration.

Silver Lake is a body of fresh water approximately 15 square miles in area, at an elevation of about 4,340 feet. The western, southern, and eastern borders of the lake consist of high escarpments; to the northwest is Paulina marsh. Silver Creek, Bridge Creek, and Bear Creek flow from Yamsay and Hagar mountains northward into Paulina marsh and thence south- eastward into Silver Lake. The water surface of the lake fluctuates considerably. During a succession of high-water years the water rises sufficiently to overflow into Thorn Lake and cover a small portion of the desert to the east. This fact perhaps accounts for the freshness of the lake. After a succession of dry years the lake surface diminishes and the waters become more and more alkaline until freshened again by another overflow. The lake dried up entirely in 1889 during an extremely dry time. The principal agricultural development at the present consists of hay lands in Paulina marsh and small irrigated tracts bordering the streams. During recent years all land suitable for agriculture has been taken as homesteads, and dry farming has been practiced with more or less success. To the northeast and practically connected with Summer Lake drainage basin is Christmas Lake Valley, a flat alluvial area com- prising 300,000 acres. This valley has no surface streams, but con- tains two or three small lakes. Alkali Flat, near the northeastern 758 SURFACE WATER SUPPLY OF OREGON, 1878-1910. part of the valley, is an intermittent lake; south of it Christmas Lake is a perennial body of water, at an elevation of 4,296 feet. North of Christmas Lake is Fossil Lake, and in the extreme southwestern por- tion and practically connected with Silver Lake basin is Thorn Lake. Nearly all the lands of Christmas Lake Valley have been taken as homesteads. Dry farming is practiced extensively and good crops of grain and potatoes and other crops have been raised. Water for domestic purposes is found in comparatively shallow wells. Near the eastern border of the valley, however, wells 40 feet deep have encountered salt water. SILVER CREEK NEAR SILVER LAKE, OREG. Location. — In sec. 28, T. 28 S., R. 14 E., 1| miles southwest of Silver Lake post office. Records presented.— November 24, 1904, to March 31, 1907; January 11, 1909, to September 30, 1910. Drainage area. — 221 square miles. Gage. — Inclined staff on the right bank. In April, 1910, the gage was found to have been raised from the true position and some of the gage readings for 1909 are therefore subject to error. Channel. — Fairly permanent; bed composed of rocks and gravel. Discharge measurements. — Made from a cable near the gage or by wading. Storage. — ^As the normal summer flow of nearly all the streams in this region is appro- priated for present irrigation requirements, any additional development will require storage. Several fairly good sites are available on Silver Creek above areas of agricultural land that could easily be irrigated from stored waters. Accuracy. — Conditions favorable for good results.

May. June. July. Aug. Note.— Daily discharge for periods of unobstructed channel determination from a cur^^e fairly well defined between 4 and .50 second-feet, but uncertain above on account of the lack of high-water measure- ments during winter floods. Due allowance has been made for backwater caused by a temporary dam below the gage for the follow- ing periods: Apr. 18 to July 20, 1905; Apr. 19 to June 30, 190G; Apr. 17 to July 18, 1909; Apr. 16 to July 6, 1910. The correction curve is defined by the rise in stage when the dam is put m, the fall when it is re- moved, and by one or two measurements each year. Corrections have been made for ice during the following periods, using the best data available: Nov. 8-13, Dec. 16-31, 19a5; Jan. 1 to Mar. 20, 1906; Dec. 19-31, 1909; Jan. 1 to Feb. 24 and Dec. 19-31, 1910.

Malheur and Harney lakes, which are in Harney County, occupy a large basin lying in general 4,100 feet above sea level and rimmed by mountain ranges whose elevation is between 5,000 and 7,000 feet. They are connected by a small strait known as The Narrows, through which the water of Malheur flows into Harney Lake. For this reason the water of Malheur Lake is practically fresh, whereas that of Harney 774 SURFACE WATER SUPPLY OF OREGON, 1878-1910. Lake is alkaline. The average rainfall in the basin is about 10 inches ; on the summit of the divide it is probably 18 inches or more. The agricultural lands in this basin comprise nearW 700,000 acres of flat alluvial soil forming a circular valley surrounding the lakes and extending like fingers into the vallej^s of tributary streams. The lower lands are more or less swampy and have for years been utilized as hay flats. During the spring months, when water is abundant, small rock-and-brush dams sufficiently high to cause the streams to overflow their banks are constructed at convenient points. Much of the meadow lands may thus be covered by a foot or more of running water during five or six weeks of the season. As the stream flow diminishes the swamp and hay lands gradually drain until the middle of July, when they are sufflciently dry to permit the cutting of hay. Comparatively small areas are cultivated, and on these the crops are limited to rye, oats, and barley. The principal industry of the region has been stock raising, and this has afforded a ready market for all grain and hay that could be raised. During recent years, however, much of the hay lands have been taken as homesteads and the better lands are rapidly being developed. The principal streams in this basin are Donner und Blitzen River, from the south, and Silvies River from the north, flowing into Mal- heur Lake ; and Silver Creek, flowing from the northwest into Harney Lake. South of Silver Creek, in a flat valley, lies Silver Lake, a small play a which is supplied by overflow from Silver Creek. Donner und Blitzen River, with its principal tributaries, Keiger, McCoy, and Mud creeks, drain the western slope of S teens Mountain. This mountain, which is the most prominent topographic feature in the area, is a long timberless ridge extending northeast and southwest, with a crest length of 60 miles or more. The eastern slope forms an abrupt escarpment; the western slope, which forms a gradual ascent, is deeply cut by canyons, into which great quantities of snow are drifted each year, the most notable being the gorge of Keiger Creek. The snows melt gradually, and the flow of the streams draining the western slope of the mountain is maintained well into the summer. The flow in late fall and winter is maintained from springs. vSilvies River drains the northern part of the Malheur-Harney basin, rising in the heart of the Blue Mountains, flowing generally southward through a broken country to Harney Valley, which it traverses in a southeasterly direction, and emptying into swamp lands bordering the northern shores of Malheur Lake. A large part of its drainage area is heavily timbered. The stream is flashy, being subject to severe floods. The summer flow is small and comes mostly from Emigrant Creek, a tributary from the west. " MALHEUR AND HARNEY LAKES DRAINAGE BASIN. 775 Silver Creek heads in a spur of the Blue Mountams and flows southeastward through Silver Creek VaUey into Harney basin. The upper part of its drainage area is well timbered, but the lower part is bare, The stream is subject to sudden floods and in summer its flow practically ceases. Between Silvies River and Silver Creek and flowing in the same general direction is Sagehen Creek, a small stream heading in a spur of the Blue Mountains and draining a rough, broken country. It empties into the marsh surrounding the northern end of Malheur Lake near the point where Silvies River enters this marsh. The eastern rim of Harney Valley is broken by a low pass known as Malheur Gap. Through this gap a drainage canal could be exca- vated that at the deepest part would not require a cut of more than 18 or 20 feet. This canal would carry the waters of the lakes into Malheur River by way of a tributary of the South Fork. Such a project was at one time begun, but riparian owners of the lake border feared that the absence of these large bodies of water would have an unwholesome effect on the climate of the basin. Accord- ingly an injunction was issued restraining the company from bufld- ing the project. MALHEUR LAKE AT NARROWS, OREG.

Location. — In sec. 14, T. 20 S., R. 31 E., at the site of a proposed dam about 3 miles southwest of Silvies, Oreg., three-fourths mile below Trout Creek, and 1^ miles west of the Burns-Canyon City road. Records presented. — May 9, 1903, to December 31, 1904; January 1, 1909, to September 30, 1910. Drainage area. — 510 square miles. Gage. — An inclined staff on left bank, 50 feet below cable. Channel. — Shifts somewhat at flood stages; bed composed of clean gravel; banks covered with heavy brush. Discharge measurements. — Made from cable or by wading. Winter flow. — Affected by ice. Storage. — A dam constructed at the site of the station will impound all the run-off from the drainage basin above it, and the water so stored could be diverted from this stream to irrigate lands in Harney Valley. The project was at one time under investigation by the United States Reclamation Service, but has since been taken up by the Silver Valley Irrigation Co. Accuracy. — Conditions fairly favorable for accurate determinations of discharge. The relation between gage height and discharge is materially affected by ice during the winter, but allowance for this factor has been made in the estimates. 778 SURFACE WATER SUPPLY OP OREGON, 1878-1910.

Mean discharge Jan. 1 to Feb. 25, 1910, estimated at 30 second-feet; discharge determined from open-channel curve Feb. 20-28 reduced, as ice was still in bottom of river. No correction for ice Mar. 1-4; values may be somewhat too high, as ice was present.

SILVIES RIVER NEAR BURNS, OREG. Location. — In sec. 7, T. 22 S., R. 30 E., 10 feet below a wagon bridge near Parker's house, 10 miles north of Burns. Records presented.— May 10, 1903, to July 24, 1906; December 14, 1908, to Sep- tember 30, 1910. Drainage area. — 940 square miles. Gages. — An inclined and vertical staff. Channel. — May shift slightly; bed composed of gravel; stream flows through a flat slluvial bottom between banks covered with a dense growth of willows and underbrush. Above a gage height of 13 feet the stream overflows a wide area. 784 SURFACE WATER SUPPLY OF OREGON, 1878-1010. Discharge measurements. — ]\Iacle from a cable at Lampshire 's ranch, 1 mile above the gage. Winter flow. — Effect of ice small. Utilization. — The water of Silvies River is largely used for the flood irrigation of hay lands in Harney A'alley. As even the flood discharge is so used, any irriga- tion project that would require the diversion of the water would involve the set- tlement of accrued water rights. Accuracy.— Conditions unfavorable for accurate determination of discharge. Discharge measurements of Silvies River near Bums, Oreg. in 1903-1906, 1908-1910.

Note.— Monthly discharge computed by adding the estimated diversion of the canal to the discharge determined from observation at the lower station. Discharge for January, 1909. and August and Septem- ber, 1910, estimated by comparison with records derived from observations at other stations and by assum- ing that the low-water discharge in 1911 was fairly representative of that in previous years. Figures originally published for the lower station for July to September, 1909, have been discarded as probably too high, for the channel was obstructed during that period. The figures for each month are liable to considerable error, but they afford a basis for an approximat^e estimate of the total yearly discharge.

Location,— In sec. 30, T. 22 S., R. 26 E., 12 miles above Riley, 3 miles below the junction with Nichols Creek. Records available. — April 14, 1904, to July 14, 1906; February 15 to December 12, 1909; April 6 to September 30, 1910. Drainage area. — 260 square miles. Gages. — Vertical and inclined staff. At the point where this station has been located Silver Creek is divided into three channels by an earth and rock dam. The original gage, established in 1904, was placed in the third or left channel. Wlien the station was reestablished in 1909 a new gage was installed on the right bank. Channel. — Clean gravel; not likely to shift. Discharge measurements. — At the original station measurements were made from the three bridges which cross the channels. After the station was reestablished in 1909 measurements were made from a cable Vv^hich was installed 50 feet below the new gage, 300 feet above the bridges, and about 100 feet above the dam. The dam is rather unstable, as the brush, earth, and smaller stones are washed away by the first flood and are not replaced until the water subsides in the spring. The 1909 gage heights were affected by these changes. Winter flow. — Relation of gage height to discharge affected by ice. Diversions and storage. — The water of Silver Creek is used to irrigate hay lands in the upper Silver Creek Valley. Below this point the valley narrows to a canyon and opens out again near Silver Lake into lower Silver Valley. During the years of low run-off no water from the upper valley reaches the lower. The Silver Creek reservoir site, which was investigated by the United States Reclamation Service and also by the Silver Valley Irrigation Co., is 3 or 4 miles above the gaging section. Water stored at this point could be used to irrigate large areas of agri- cultural lands on both sides of the stream. Accuracy. — Results at this station are only approximate.
