MAP OF OREGON SHOWING PRINCIPAL RIVERS.

SURFACE WATER SUPPLY OF OREGON.

By F. F. HENSHAW and H. 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 hydrography continued in existence as a part of the topographic branch 

of the Survey.

Since the fiscal year ending June 30, 1895, successive sundry civil 

bills 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; Umatilla 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 measurements 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 Reclamation 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

resources of the State, and a like amount for topographic mapping1, 

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 placed in charge of all 

hydrometric investigations 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 previously 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 engineer and the Director of the United States Geological 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 agreements the present report has been prepared. The report embraces hydrometric data from 1878 to September 30,1910. The results of measurements for the years ending September 30, 1911 and 1912, have 

been published in 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 insure their best 

possible interpretation. For example, the daily discharge for a 

station may be computed the first year from a poorly denned rating 

curve; the next year, with additional measurements, a somewhat 

different curve may fit all the points better without indicating that 

any change in channel has occurred. The second curve is therefore 

more truly applicable 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 

unless 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 acknowledged in the description of the stations. Special acknowledgment 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 "discharge" 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 secondfeet, 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, secondfeet per square mile, run-off in inches, and acre-feet. They may 

be denned 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 rectangular 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 usually expressed in depth 

in inches.
SURFACE WATER SUPPLY OF OREGON, 1878-1910.

An "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 terms 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 flow" for a given gaging station is that point 

on the gage the gage height to which the surface of the river 

would fall if there were no flow.

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. Therefore 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 regarding 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 elevation 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 AKD 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 known 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 discharge tables are computed.

The rating table gives, either directly or by interpolation, the discharge in second-feet corresponding to every stage of the river recorded during the period for which it is applicable. It is not published 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 monthlydischarge table. For the rating curves "well 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 very 

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 does not 

apply to the estimate of maximum or minimum discharge nor to 

that for any one day, but to the monthly mean. 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 monthly 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 districts 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 misleading 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:

All figures of "second-feet pel square mile" and "run-off, depth 

in inches" previously published by the Survey should be used with 

extreme caution, and such figures in this report should be used with 

care because of possible inherent sources of error not known to the 

Survey.

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 computations. 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 discharge allow more detailed studies of the variation in flow. It 

should be borne in mind that the observations in each succeeding 

year may be expected to throw new light on data already collected 

and published.

NATURAL FEATURES OF OREGON. 1

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.2 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 Willamette, 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 Mountains, which has also been 

deeply dissected by erosion. The most important valleys in this

10 SURFACE WATER SUPPLY OP OREGON, 1818-1910.

ridge are occupied by Rogue, Coquille, and Illinois rivers. In the 

northeastern part of the State are the Blue Mountains and the Wallowa Mountains, in which the general elevation is 8,000 feet and 

isolated peaks rise to greater height. The most important streams 

flowing 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 mountains 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 are 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 marely playas.

The topography of the region thus includes types ranging from 

the chaotically wild gorges of the Snake River basin to the level sagebrush plains of the Umatilla or the rolling prairies of Willamette 

Valley. 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 Valley 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 remarkable steadiness of flow of Deschutes and Klamath rivers and their

tributaries.

CLIMATE. 1

Mean temperature in Oregon differs with elevation and with distance 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 temperature 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 temperatures for Portland and Ashland have been 102° and 108° F., respec1 Abstracted from Climatology of the United States: U. S. Dept. Agr. Weather Bur. Bull. Q, pp. 

948-969,1906.
NATURAL FEATURES OF OREGON. 11

tively; 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 temperatures 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 Valley east of the Cascades, and 

from 12 to 25 inches in the foothills 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.

KIVEKS.

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, Coquille, Rogue, and 

Klamath rivers. (See PI. 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 

Blitzeu, and Silvies rivers; the important lakes are Warner, Harney, 

Malheur, Abert, Summer, and Silver lakes.

Goose Lake, in south-central Oregon and northern California, occupies a valley 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 tributary 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 Cascade Mountains.
12 SURFACE WATEE SUPPLY OP OREGON, 1878-1910.

The 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 Malheur, 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 precipitation 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 extreme low stage.

COLUMBIA RIVER DRAINAGE BASIN.

GENERAL FEATURES.

Columbia River has its source in Columbia Lake, in the eastern division 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 EIVEE DRAINAGE BASIN.

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

Montana.................................................... 25,000

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. Between the mountain ranges are rolling, rough, and mountainous tablelands. 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).

1 Parts of the Columbia and its tributaries marked with asterisk are navigable under favorable conditions. 

Practically all these stretches of river can be made navigable at all seasons of the year at comparatively small 

expense. Columbia and Snake rivers were formerly navigated throughout the year, except during occasional blockades from ice, from Celilo to Lewiston. 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 carried 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 Cascade 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 8J 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 fche 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 niches 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 niches. 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 during 

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 all the variations from the rigorous 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 humid country that, strictly speaking, is arid in the summer months.
16 SITEPACE 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 development 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. The 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 temporary 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 invariably 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 AT THE DALLES, ORE6.

Location. In sec. 34, T. 2 N., R. 13 E., at the dock of The Dalles, Portland & Astoria

Navigation Co., 2,000 feet below the ferry at The Dalles, about 18 miles below

Deschutes River and above Hood and Klickitat rivers. 

Records presented. June 1, 1878, to September 30, 1910; maximum stages, 1858

to 1877. 1

Drainage area. 237,000 square miles. 

Gage. Vertical staff in several sections, attached to piling; datum 46.36 2 feet above

sea level; known as the Brooks gage; maintained by the United States Weather

1 Discharge estimates 1879 to 1910 have been recomputed and estimates published in this report supersede those published in Water-Supply Papers 252,272, and 292 of the United States Geological Survey,

2 As referred to the primary level net of 1912.
COLUMBIA EIVEE 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 discharge 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.

Bating 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 annual 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 improve 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 materially in error. '

18 SURFACE WATER SUPPLY OP OREGON, 1818-1910.

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-feet, 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. The cost of the flood 

measurements of 1913 and of the recomputation of discharge has been paid by the 

United States Reclamation Service and from the appropriation made by the State 

of Oregon for the investigation of water-power possibilities at The Dalles.

NOTE. Channel below gage at Cascade Locks occasionally obstructed by ice which was noted by the 

observer, as follows: 1879, Dec. 23, large cakes of ice running; 1880, Dec. 4-14, river closed to navigation: 

1883, Feb. 4-26, river closed to navigation; 1884, river closed with ice Jan. 23 to Feb. 1 and Feb. 8-27, and 

gage frozen up Dec. 16-18 and 22; river closed with ice above locks Dec. 16,1884, to Feb. 4,1885, Jan. 17-29, 

1886, and Feb. 4-18,1887; 1888, ice in river Jan. 6-29, and no boat ran to The Dalles until after Feb. 5; no 

boat to The Dalles Jan. 17-30,1889, but no other notes of ice. Extremely cold weather began about Dec. 

12, 1889, and lasted until about Feb. 1,1890, uearly 10 feet of snow falling during this period; river froze 

over Jan. 2, both gages were frozen up Jan. 4 and no regular readings made until Jan. 17. On Jan. 17 the 

gage below the locks was read, evidently by chopping away the ice. The river opened and a boat arrived 

from The Dalles Feb. 3; river frozen again Feb. 25; river blocked with floating ice Dec. 21-23,1892. Ice 

notes after 1892 are rather meager.

66 SURFACE WATEB SUPPLY OF OREGON, 1878-1910.

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, broadening 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 Lewistoh 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, Malheur, Burnt, and Powder rivers, Pine Creek, Imnaha, and Grande 

Ronde rivers.

OWYHEE RIVER DRAINAGE BASIN. 

GENERAL FEATURES.

Owyhee River rises in the Humboldt National Forest in the northcentral part of Nevada, flows north, then northwest across the corner 

of Idaho and into Oregon, where it turns abruptly and flows northeastward to its junction with Snake River, near Nyssa, Oreg., exactly 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 headwaters, and even there they are small and the trees are those characteristic 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 all 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.

OWTHEE 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 somewhat 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.

Discharge measurements of Owyhee River at Owyhee, Oreg., in 1890,1894-1897,1903-1908.

NOTE. Daily discharge determined as follows: 1890 to 1893. From rating curves well denned between

COLUMBIA RIVER DRAINAGE BASIN. 89

MALHEUR RIVER DRAINAGE BASIN. 

GENERAL FEATURES.

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 headwaters to 2,000 at the mouth. The country is in general rough and 

broken and is largely covered with sage brush. Irrigation is restricted to the lower lands immediately adjoining the streams. The 

headwater areas are lightly forested, but elsewhere the area is timberless 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 contemplated 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 

earlier records are not so dependable as those of later years.

MALHEUR RIVER ABOVE SOUTH FORE, 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 office. 

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.

NOTE. Daily discharge determined as follows: 1906 and 1907, from poorly defined rating curve; discharge for January, 1907, estimated on account of ice; Jan. 1,1908, to Mar. 2,1910, from curve well defined 

between 60 and 800 second-feet; Mar. 3 to May 25, 1910, from fairly well denned curve; July 1^5,1909, 

estimated from a hydrograph and Dec. 11-31 estimates reduced 10 per cent on account of ice. 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. Discharge 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.

COLUMBIA RIVER DRAINAGE BASIF. 95

MALHETTR RIVER BELOW SOUTH FORE, 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.

NOTE. Gage heights for 1909 are somewhat uncertain, as several gages, referred to slightly different 

datums, were used, and it is not always certain just which gage the observer used. They nave been corrected to uniform datum as closely as possible. Readings Jan. 17-23 and May 15-30 are believed to be 

erroneous. 

River probably frozen during a part of January and February, 1909 and 1910; effect somewhat uncertain.

CANALS IN MALHEUR RIVER BASIN.

Systematic measurements of diversions from Malheur River were 

begun by the United States Reclamation Service hi 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 hi October and November, 1904, though no record 

was kept after September 30.

150 SURFACE WATER SUPPLY OP OREGON, 1878-1910.

POWDER RIVER DRAINAGE BASIN.

GENERAL FEATURES.

Powder River, which drains the eastern slope of the Blue Mountains, 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 irrigation' 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 f ailing 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 SALISBURY,! OREG.

Location. In the SW. i sec. 30, T. 10 S., E. 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.

NOTE. Daily discharge determined as follows:

1904 to 1906.. From rating curve fairly well defined below 800 second-feet, except for ice period, Jan. 1 to 

Feb. 24,1906, and Nov. 19,1906, to Feb. 12,1907, for which curves were poorly defined.

1907. From fairly well defined curves.

1908. From poorly defined rating curve; estimated because of ice, Dec. 22,1907, to Jan. 4,1908.

1909. From fairly well defined curve. Discharge for Jan. 1-16 and Dec. 10-31 obtained by open-channel 

curve reduced 20 per cent to counteract effect of ice.

POWDER RIVER NEAR NORTH POWDER, OREG.

Location. In the NW. i sec. 26, T. 6 S., R. 40 E., at proposed dam rite 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 flow. 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. 

Cooperation. Gage readings furnished in part by Powder Land & Irrigation Co.

Discharge measurements of Powder River near North Powder, Oreg., in 1909-1910.

NOTE. Daily discharge determined as follows:

1909. From well-defined rating curve; May 6-22, interpolated; Nov. 8-22, discharge obtained by openchannel curve reduced 20 per cent on account of ice.

1910. From curve well defined between 15 and 1,000 second-feet.

Discharge f9r December, 1909, and January and February, 1910, can be estimated approximately by 

taking twice the discharge at Salisbury and interpolating for the period Mar. 1-7.

EAGLE CREEK NEAR BAKER, OREG.

Location. In sec. 21, T. 6 S., R. 43 E., 700 feet below mouth of West Fork of Eagle 

Creek, 35 miles northeast of Baker.

Records presented. May 20, 1909, to September 10, 1910.

Drainage area. About 33 square miles.

Gage. Vertical staff.

Channel. Gravel and cobblestones; very rough; shifts slightly.

Discharge measurements. Made from footbridge or by wading.

Winter flow. -Not affected by ice at any time during which record was being 

obtained.

Diversions. The Sparta ditch an old hydraulic mining ditch diverts water from 

Eagle Creek and West Fork some distance above their confluence and carries it 

around the west side of the valley to the vicinity of Sparta. On July 14, 1911, 

this ditch was carrying 14.5 second-feet. It is used 5 or 6 months of wannest 

weather.

Accuracy. Results good in 1909 and part of 1910.

Cooperation. Records furnished by Powder Land & Irrigation Co.

166 SURFACE WATER SUPPLY OF OREGON", 1878-1910.

GRANDE RONDE RIVER DRAINAGE BASIN.

GENERAL FEATURES.

Grande Ronde River, which drains the eastern slope of the Blue 

Mountains in Oregon and the northern slopes of the Wallowa Mountains (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., about 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 drains the northern part of the Wallowa National Forest, the 

Wallowa, which rises in the southern slopes of the Wallowa Mountains, 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 mountain ranges which slope gradually 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 inches. 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 production of wheat, and irrigation has not been practiced to an elaborate 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 RIVER BBAINAGB 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.

NOTE. Daily discharge determined as follows:

1903 and 1904. Nov. 5,1903, to Apr. 12,1904, from rating curve well defined between 40 and 1,000 secondfeet; Apr. 13 to Dec. 31. 1904. from curve fairly well defined between 30 and 2,500 second-feet; Apr. 26, 

May 8 and 11, Oct. 2,12, and 27, Nov. 5 and 18,1904, interpolated, as stream was being used for logging 

operations.

1905. From rating curve well defined above 40 second-feet.

1906 and 1907. From curve fairly well defined between 30 and 1,200 second-feet. 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. Discharge 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 effect 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 are accordingly subject to error.

NOTE. Comparison of monthly 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 for the early part of 1908 may be too large.

GRANDE RONDE RIVER AT ELGIN, OREG.

Location. In sec. 14, T. 1 N., R. 39 E., at the county bridge, one-fourth mile east 

of the railroad station, at the lower end of the Grande Ronde Valley.

Records presented. November 18, 1903, to September 80, 1910.

Drainage area. 1,350 square miles.

Gage. Standard chain; vertical staff at same datum used prior to July 21, 1904.

Channel. Heavy gravel and small bowlders; fairly permanent.

Discharge measurements. Made from bridge or by wading.

Winter flow. Ice forms for a considerable period each winter, and has probably 

introduced some error into past records.

Diversions. Large part of low-water flow diverted above station for irrigation in 

Grande Ronde Valley. No storage developed.

Accuracy. Results fairly good.

WALLA WALLA RIVER DRAINAGE BASIN. 

GENERAL FEATURES.

Walla Walla Kiver rises on the western slope of the Blue Mountains 

and flows westward into the Columbia. Its drainage basin lies immediately 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.

Climate and soil combine to make the country wonderfully productive, 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 double 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 lies 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 causing great damage to life and property.

WALLA WALLA RIVER AT MILTON, OREG.

Location. In sec. 11, T. 5 N., R. 35 E., about 1 mile south of post office in town of 

Milton.

Records presented. February 13, 1903, to September 30,1905.

Drainage area. 130 square miles.

Gage. Vertical staff.

Channel. Gravel; shifting.

Discharge measurements. Made at county bridge one-half mile below gage, 

except as noted.

Diversions. A ditch diverts water between the gage and the bridge from which 

measurements are made. The measured discharge of the ditch has been added 

to that of the river in the following list.

Accuracy. Conditions at this station poor and estimates generally uncertain, especially after about July 1, 1904, when the discharge relation was affected by 

backwater from a diversion dam below the gage.

. TJMATILLA RIVER BASIN. 

GENERAL FEATURES.

Umatilla River rises in the northeastern corner of Umatilla County, 

Oreg., flows generally westward a distance of 80 miles, and unites 

with Columbia River at the town of Umatilla. The area above the 

town of Pendleton spreads out in fan shape, including the western 

slope of the Blue Mountains for a distance of about 70 miles.

The principal tributaries are Birch, McKay, and Meacham creeks. 

The drainage area measures 2,160 square miles at the mouth of the 

river, 640 square miles at Pendleton, and 353 square miles at Gibbon.
. COLUMBIA RIVER DRAINAGE BASIN. 231

The mean annual rainfall ranges from about 30 inches on the 

summit of the Blue Mountains to 9 inches at the mouth of the stream, 

being 14 inches at Pendleton and 25 inches at Weston on the divide 

between Umatilla and Walla Walla rivers. The headwater regions 

of the stream are heavily forested, but downstream the forests give 

place to rolling table-lands devoted to the production of wheat. The 

immediate valley of the river has been irrigated for many years, and 

the entire low-water flow of the stream is appropriated for irrigation. 

The United States Reclamation Service has completed a project to 

irrigate about 20,000 acres near Hermiston, and has begun work on 

the West Extension, which will water about 30,000 acres along the 

Columbia River near Irrigon. The soil of this portion of the drainage 

basin is sandy and the climatic conditions are favorable for the production of fruit. The highest run-off since records have been kept 

occurred in 1900 and the lowest in 1905.

UMATILLA EIVEE AT GIBBON, OEEG.

Location. In the NW. \ sec. 36, T. 3 N., R. 35 E., on the Umatilla Indian Reservation, 1 mile below Gibbon railroad station, about 1J miles below the mouth of 

Meacham Creek, and 2 miles above the mouth of Squaw Creek; above all diversions.

Records presented. July 22, 1896, to December 31, 1899; April 15, 1900, to May 

29,1906; December 3, 1906, to March 31,1907; September 13, 1907, to September 

30, 1910.

Drainage area. 353 square miles.

Gage. Vertical staff in two sections; datum unchanged since December 3, 1906. 

Gages at several locations and datums used during life of station.

Discharge measurements. Made from a cable near the gage or, at low water, by 

wading. Several cables used.

Channel. -Gravel; likely to shift at each flood.

Winter flow. Slightly affected by ice.

Artificial control. No water stored or diverted above station.

Accuracy. Results since October, 1904, good, except estimates of extreme highwater discharge, which are uncertain. Many of the records prior to May, 1904, are 

very uncertain on account of shifting conditions and lack of sufficient measurements.

UMATILLA RIVER AT PENDLETON, OREG.

Location. In sec. 10, T. 2 N., R. 32 E., at Main Street Bridge, in the town of Pendie ton.

Records presented. February, 1891, to July, 1892; May 22, 1903, to March 21, 

1906.

Drainage area. 640 square miles.

Gage. Vertical staff fastened to center pier of bridge.

Channel. Gravel; shifts somewhat.

Discharge measurements. Made from different bridges in vicinity of station or, 

at low water, by wading.

Diversions. Byera Mill ditch diverts water about 1J miles above station and retuma 

it to river about 200 feet above gage. Considerable fluctuation in the discharge 

ie caused by unsteady operation of mill. The Farmers Mill ditch diverts water 

just above gage and returns it about 4,000 feet below; prior to June, 1904, it 

diverted about 40 second-feet; after that the quantity varied. 1

1 For records of this ditch see p. 254.
250 SURFACE WATER SUPPLY OF OREGON, 1878-1910.

Accuracy. Results for 1903 and 1904, fair; for 1905, good. Discharge for June to 

December, 1904, can not be computed, as most of the flow was diverted in the 

Farmers' Mill ditch, no record of which is available. 

Cooperation. Records for 1891-92 furnished by Mr. A. L. Adams, chief engineer

of the Umatilla Irrigation Co.; accuracy of records not known. 

The following measurement was made by W. T. Trowbridge: 

January 24, 1894: Gage height on gage of Umatilla Irrigation Co., 1.53 feet; discharge, 239 second-feet.

NOTE. Daily discharge determined as follows:

1903. From fairly well denned rating curve.

1904. From fairly well defined curve; Apr. 1-27, estimated as the sum of discharge of Umatilla River at 

Pendleton, McKay Creek, and Birch Creek, the discharge of which was estimated as one-half that of 

McKay Creek; Aug. 16 to Sept. 4, estimated at 42 second-feet.

1905. From fairly well denned rating curve.

1906. From curve well defined below 8,000 second-feet.

1907 to 1909. From curve well defined between 100 and 8,000 second-feet. Discharge Mar. 16,1908, estimates from records at Umatilla. Discharge Jan. 10-16, 1909, determined from open-channel curve 

reduced 40 per cent; Jan. 17-19, interpolated on account of ice; Jan. 30 to Feb. 21. determined from 

corrected gage heights based on a relation curve between this station and that at Gibbon; approximate. 

(See footnote to gage heights.)

1910. From two fairly well-defined rating curves applicable Jan. 1 to Mar. 2 and Mar. 3 to Sept. 30. Discharge determined from open-channel rating curves Jan. 3-10 reduced 10 per cent, and Jan. 11-17,20 per 

cent to counterbalance effect of ice.

UMATILLA RIVER NEAR UMATILLA, OREG.

Location. In sec. 21, T. 5 N., R. 28 E., 1J 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 CHEEK BASIN. 

GENERAL FEATURES.

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.

COLUMBIA RIVER DRAINAGE BASIN. 287

JOHN DAY RIVER BASIN. 

GENERAL FEATURES.

John Day River drains the country to the northwest of the Blue 

Mountains. 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 little has been accomplished. 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 

undertaken 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.

JOHN DAY. RIVER NEAR DAYVILLE, OREG.

Location. In sec. 4, T. 13 S., E. 27 E., at a private wagon bridge about 3 miles above

Dayville and the mouth of South Fork.

Records presented. November 23,1908, to September 30,1910. 

Drainage area. 1,000 square miles. 

Gage. Vertical staff. 

Channel. Sand and gravel; probably slightly shifting; banks low below bridge and

river overflows at about gage height 3 feet. 

Discharge measurements. Made from the down rail of private wagon bridge, to

which gage is attached, or, at low water, by wading. 

Winter flow. Affected by ice for short periods. 

Diversion. Many private ditches take water from river above station; quantity

diverted unknown. 

Accuracy. Results good.

DESCHTTTES RIVER BASIN.

GENERAL, FEATURES.

Desclmtes River has its source in a number of mountain lakes at 

the summit of the Cascades just over the mountains from the headwaters of Willamette River, and its course is northward to the Cqlumbia, which it enters about 15 miles above The Dalles.

The principal tributaries of Deschutes Kiver are White, Warmsprings, Metolius, and Crooked rivers, and East Fork. All except 

Crooked River drain the eastern slope of the Cascades and contribute 

the larger portion of the stream flow.

The drainage area of the river is largely indeterminate, as there are 

large areas along the topographical border of the basin which
COLUMBIA RIVEK DRAINAGE BASIN. 305

no surface streams, the water all sinking into the soil and underlying 

rock and draining off underground.

Topographically the area is rough and mountainous. The agricultural lands consist largely of high table-lands cut by deep canyons 

through which the rivers flow, and small arable areas which border 

the streams. The soil is a coarse disintegrated lava. The rocks of 

the entire area are volcanic and so peculiarly porous that the basin 

has the effect of a huge sponge. The flow of the Deschutes is more 

remarkably uniform than that of any river in the United. States comparable with it in size, and its economic value is almost incalculable. 

At the mouth of the stream the maximum flow is only six times the 

minimum. Ocular evidence of this uniformity of flow is presented 

by the low grass-grown banks between which the river flows for its 

entire course.

The general elevation of the lands around Bend is 3,600 feet above 

sea level; that of the summit of the Cascade Mountains is from 5,000 

to 6,000 feet. Prineville is 2,868 feet above sea level, and Paulina, 

near the upper portion of the Crooked River basin, 3,684 feet.

The only heavily timbered portion of this drainage basin is found 

on the eastern slope of the Cascades, and constitutes about 15 per cent 

of the total area. The divide between Crooked River and the John 

Day basin is sparsely timbered. The uniform flow of this stream can 

not be attributed to forestation. Indeed the entire timber supply 

could be removed without in the least affecting the flow of the river.

The annual rainfall ranges from 100 inches on the summit of the 

Cascade Mountains to 10 inches along the main course of the stream. 

Twenty-five miles farther east, at Prineville, the mean annual rainfall is 9 inches; at Warm Springs, 11 inches; at Bend, 15 inches. On 

the headwaters of Crooked River the precipitation is probably 20 

inches or more.

Although the winter temperatures are low, ice does not usually 

affect the flow of the streams, for the winter flow is derived largely 

from springs. The high stages usually occur during the months of 

April, May, and June, and result from the melting of snows in the 

mountains, although occasionally floods are caused by "chinook" 

winds in the early spring or late fall.

It has been estimated that Deschutes River between Benham Falls 

and its mouth, a distance of 140 miles, together with its principal 

tributary, Metolius River, is capable of furnishing about 600,000 

horsepower from the low-water flow after all water possible has been 

diverted for irrigation. The United States Geological Survey has published a report on Deschutes River and its utilization,1 in which its water 

powers are described and the conditions of development discussed.

DESCHUTES EIVEE AT WEST S EANCH, NEAE LAVA, OEEG.

Location. At private bridge on B. F. West's ranch, in the SW. J sec. 31, T. 19 S., 

R. 11 E., about 2 miles north of Lava, about 16 miles above Bend, and about 7 

miles by river above Benham Falls, one-half mile below Spring Creek, and 2 

miles below East Fork.

Records presented. July 21, 1906, to February 20, 1909.

Drainage area. Indeterminate.

Gage. Vertical staff spiked to bridge approach; datum unchanged.

Channel. Sand and gravel; somewhat shifting; affected by weeds. Gradient of 

river is very flat less than 2 feet per mile.

Discharge measurements. Made from private wagon bridge of logs and poles.

Winter flow. Unaffected by ice.

Accuracy. Results good.

As this station gives practically the same discharge as the station at Benham Falls, 

the tables of monthly discharge of the two have been combined (p. 322).

NOTE. Daily discharge determined as follows: 

1906. From well-defined rating curve. 

1907 to 1909. From curve well defined between 1,400 and 2,200 second-feet, except for short periods, which

majr be affected by backwater, as indicated by the erratic plotting of some measurements.
318 SURFACE WATEB SUPPLY OF OREGON, 1878-1910.

DESCHUTES BIVEB AT BENHAM FALLS, NEAB BEND, OBEG.

Location. In the NE. i sec. 16, T. 19 S., R. 11E., about 250 yards above Benham 

Falls, and 14 miles above Bend; above the more important irrigation diversions 

from Deschutea> 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 station are 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 

Metoh'us 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.

Discharge measurements of Deschittes River at Benham Falls, near Bend, Oreg., 1909-10.

COLUMBIA RIVER DRAINAGE BASIN. 327

DESCHTJTES RIVER AT BEND, OREG.

Location. In the NE. J sec. 32, T. 17 S., R. 12 E., just below the power house of the 

Bend Electric Light & Power Co., at city pumping plant at Bend, 1 mile above 

the diversion dam of the North canal of the Central Oregon Irrigation Co.

Records presented. April 23, 1907, to September 30, 1910.

Drainage area. Indeterminate.

Gage. Vertical staff bolted to a bowlder.

Channel. Very rough and rocky, somewhat shifting. Logs lodged below cause a 

somewhat varying degree of backwater.

Discharge measurements. Made from Staat's bridge, three-fourths mile above 

pumping station and Bend dam; conditions unfavorable.

Winter flow. Unaffected by ice.

Diversions. The Pilot Butte and Central Oregon canals of the Central Oregon 

Irrigation Co. divert water 5 miles by river above the present gage and measuring 

section, and have been operated since 1905. No other important diversions. No 

storage yet developed.

Accuracy. Records covering the period January 1, 1909, to September 30, 1910, are 

good, and for certain parts of the period excellent.

Cooperation. Gage heights furnished by C. A. Stanburrough, engineer of the 

pumping plant.

COLUMBIA EIVEE DRAINAGE BASIN. 331

CENTRAL OREGON CANAL NEAR BEND, OREG.

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. 

Cooperation. Gage-height record furnished by the Central Oregon Irrigation Co.

Discharge measurements of Central Oregon canal near Bend, Oreg.,for 1905-1910.

DESCHUTES RIVER AT MOODY, NEAR BIGGS, OREG.

Location. In the SE. J sec. 26, T. 2 N., R. 15 E., opposite Moody railroad station, 

1J miles above the bridge of the Oregon-Washington Railroad & Navigation Co., 

about 5 miles southwest of Biggs, and If 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 RIVER 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.

NOTE. Discharge for Mar. 1-14 and June to Oct., 1908, estimated by comparison with discharge at West's 

ranch.

Mean for Nov. 6-30,1908, taken as mean for the month.

Monthly means for April to September, 1910, were obtained from comparisons with the discharge of 

upper Desehutes River and its tributaries. The results obtained in different ways are so consistent that 

the values used can not be much in error.

COLUMBIA EIVEE DRAINAGE BASIN. 390

SQUAW CREEK NEAR SISTERS, OREG.

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.

NOTE. Conditions were changed early in November, 1906, by washing out of dam below; this was replaced Nov. 28, and washed out again Dec. 3. 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 was 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.

COLUMBIA EIVER DRAINAGE BASIN. 409

CROOKED RIVER NEAR POST, OREG.

Location. In sec. 7, T. 17 S., R. 21 E., 12 miles above Post and half a mile below

mouth of North Pork of Crooked River, at a point locally known as "Stewarts

grade," just below dam site of proposed reservoir. 

Records presented. November 9, 1909, to September 30, 1910. 

Drainage area. Indeterminate. 

Gage. Combination vertical staff and inclined staff. Vertical staff read at low water;

datum lowered 1 foot October 22,1909. All gage heights reduced to new datum. 

Channel. Rocks and bowlders; probably permanent.

Discharge measurements. Made from cable at gage section. Conditions poor. 

Winter flow. Stream freezes and water sometimes flows over ice; discharge relation

affected for two or three months each winter. Estimates of discharge during such

periods have generally been made by comparison with records of the Prineville

station. 

Diversions. A considerable and unknown quantity of water is diverted for irrigation

above the station. 

Accuracy. Results only fair on account of unfavorable conditions.

COLUMBIA RIVER DRAINAGE BASIN. 415

OCHOCO CREEK AND ELLIOTT DITCH AT ELLIOTT'S RANCH, NEAR PRINEVILLE, OREG.

Location. In the NE. | 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 development of the Ochoco project of the United States Reclamation Service.

Becords 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 

Elliott 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.

HOOD BIVEB BASIN. 

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 supplied 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 10J 

miles above Hood River.

Becords available. November 17, 1905, to March 16, 1907; January 16 to September 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 BASIK. 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.

NOTE. From March to June, 1906, there was more or less backwater, caused by debris. The flow is 

influenced by logging dams about 2 miles above the station. These gage heights represent only approximately the daily means.

Gage heights for 1910 refer to a datum 0.5 foot higher than that used in 1905 to 1907. No ice at this 

station.

SANDY RIVER BASIN. 

GENERAL FEATURES.

Sandy River rises in the glaciers of Mount Hood and flows northwestward, uniting with Columbia River at Troutdale. It drains the 

western slope of the Cascade Mountains at their northern extremity 

in Oregon.
COLUMBIA EIVEE DRAINAGE BASIN. 433

The principal tributaries of the Sandy are Bull Run River, which 

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, Government 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 Government Camp 87 inches. It is likely, however, that the figure 

for Government Camp is not representative because of the close 

proximity of the statiopi to Mount Hood. A large part of the precipitation on the headwjaters falls as snow. In the foothills, 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 availability for municipal \jrater 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, howjever, grown up in second-growth timber and 

the underbrush is almost impenetrable.

BULL RUN EIVER NEAR BULL RUN, OREG.

Location. In sec. 25, T. IS., B. 5 E., 1J miles above the intake of pipe line of 

Portland water supply, about half a mile below South Fork.

Records available. August 20, 1907, to September 30, 1910; also reading on a gage 

installed by the city water department January 5, 1895, to November 13, 1906.

Drainage area. 102 square miles.
COLUMBIA BIVEE DRAINAGE BASIN. 445

Gage. Friez automatic since August 1, 1909; inclined staff about 1,000 feet above 

the screen house at the head works since 1907. The earlier readings were made on 

gages at the same location as the inclined staff and have been referred as nearly 

as possible to the same datum.

Channel. Gravel and bowlders at upper gage; shifts somewhat; large rocks at the 

lower gage, but the discharge relation during the low-water periods has been 

affected by backwater from a temporary brush and log diversion dam constructed 

each year and washed out by the first high water in the fall.

Discharge measurements. Made from cable at site of recording gage or by wading.

Accuracy. Results good since 1907. Earlier records uncertain on account of question as to permanency of channel and especially as to gage datum. Low-water 

results should not be given much weight, but the total yearly run-off is probably 

nearly as good as for later years.

Cooperation. Gage heights furnished by Portland water board; the entire record 

prior to August, 1907, worked up by the water engineer of the city.

NOTE. Discharge Dec. 1,1903, to Nov. 19,1904, and Nov. 14,1906, to Aug. 19,1907, estimated from readings on gage No. 2, so called, in the concrete canal leading from the river to the screen house at the headworks. These readings bear a very uncertain relation to the discharge and the records are only roughly 

approximate.

WILLAMETTE RIVER BASIN. 

GENERAL FEATURES.

Willamette River drains a trough-shaped area, extending north and 

south between the Coast and Cascade ranges in Oregon. The area is 

roughly rectangular, approximately 140 miles long and about 85 miles 

wide. The Willamette proper is formed by the junction of three main 

tributaries which unite in the vicinity of Eugene; these are Middle 

Fork (considered the continuation of the main stream), Coast Fork, 

and the McKenzie. The river is navigable for ocean-going vessels 

from the mouth to Portland, and for ordinary river steamboats from 

Portland to Corvallis, except during a few months each year. From 

Corvallis to Eugene the river is navigable for light-draft boats during 

medium stages of the river. The falls of Willamette River at Oregon 

City are passed by a series of five locks, which have just been purchased by the United States.

The other principal tributaries of the Willamette are Santiam, Mollala, and Clackamas rivers. From the Coast Range flow Long Tom, 

Marys, Luckiamute, Yamhill, and Tualatin rivers. The drainage

areas of this river and its principal tributaries are given in the following table:

From the summit of the mountain ranges the slopes are steep, but 

they merge gradually into a wide alluvial valtay or gently rolling 

agricultural lands.

The entire drainage area may still be considered densely forested. 

The portions of the basin that contribute to the flow of the streams are 

almost entirely within the boundaries of the national forests, and privately owned timberlands extend from the boundaries of the national 

forests to the main stream in the valley, except where lands have 

been cleared.

Although records of precipitation at the summit of the Coast Range 

are meager, it is likely that the total annual rainfall is as much as 150 

inches. On the eastern slope of the Coast Range precipitation decreases very rapidly to about 40 inches, but it gradually increases 

again until at the summit of the Cascade Range it is approximately 

100 inches. From north to south the same general variation is 

observed, although the differences are not so striking. At the mouth 

of the river the precipitation is approximately 50 inches, in the vicinity 

of Corvallis about 40 inches, and at the summit of the Calapooya 

Mountains, which form the southern boundary of the drainage area, 

55 or 60 inches. Except on the summits of the mountain ranges this 

precipitation is almost entirely rain, 95 per cent falling during nine 

months, from September to May. On the mountain ranges part of 

the precipitation is snow, and the country is subject during the spring 

and-fall to warm chinook winds accompanied by rather sudden melting 

of these snows, which frequently cause considerable damage from 

floods. During the growing season, when the precipitation rarely 

exceeds 2 inches, the country is practically arid. Although irrigation 

has not long been practiced in the valley, it is likely that before many 

years a large part of the agricultural bottom lands will be placed under 

irrigation. Small ditches and pumping plants have been constructed, 

and the returns from irrigated agricultural lands show an increase of 

from 50 to 500 per cent in production over the nonirrigated lands.
468 SURFACE WATER SUPPLY OF OREGON, 1878-1910.

Lying almost wholly within a narrow strip adjacent to the main 

divide of the Cascades, where the soil and underlying rock is porous, 

like that in the basin of Deschutes River, on the east side of the range, 

are a number of lakes and marshes which afford favorable sites for 

storage reservoirs. As a result the streams flowing through the lakes 

and marshes experience no pronounced floods and are characterized 

by a large low-water flow. The effect of reservoirs on the Willamette would not be so marked as on more flashy streams, but their 

operation would greatly enhance the value of the river for irrigation, 

power, and navigation.

The highest known flood hi the Willamette Valley occurred December, 1861, when the discharge at Albany was 302,000 cubic feet per 

second. The highest gage reading at Portland since that date occurred in 1894, but was due to backwater from Columbia River. The 

years 1899 and 1907 were "wet years." The year 1905 was a comparatively dry year. The longest record of stream flow in this basin 

has been obtained by applying recent measurements made at Albany 

to records obtained by the United States Weather Bureau since 1878.

The results of profile studies in the Willamette basin have been published by the United States Geological Survey as Water-Supply 

Paper 349.

NOTE. Daily discharge determined from a rating curve well defined between 2,700 and 13,600 secondfeet and fairly well defined above. 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.

COLUMBIA RIVEB DRAINAGE BASIN. 535

SANTIAM BIVEE AT JEFFERSON, OREG.

Location. In the NE. | sec. 11, T. 10 S., R. 3 W., at the Southern Pacific Railroad 

bridge in Jefferson, about 2^ miles below junction of North and South forks and 

about 9 miles above mouth.

Records available. October 8j, 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 Stay ton; 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 measurements of Santiam River at Jefferson, Oreg., in 1905-6 and 1908-1910.

NOTE. Daily discharge computed as follows: Aug. 1 to Nov. 20,1909, from rating curve for 15-foot weir 

allowance has been made for possible roundness of crest, velocity of approach, and leakage, approximate; 

Nov. 21-23, 1909, estimated by an engineer who was on ground at time; Nov. 24,1909, to Jan. 15,1910, 

from a rating curve derived from the curve for weir and comparative readings on the lower and weir gages; 

poorly defined for January.

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-feel and fairly well denned for higher stages.

Monthly discharge of Marion Fork of Santiam River at Marion Lak", near Hoover, Oreg.,

for 1909-10.

according to stages, in making these readings.

well defined between 50 and 1,000 second-feet, and the other applicable Feb. 1,1907, to July 12,1909, well 

defined between 60 and 1,000 second-feet. Discharge Feb. 5-7, 1907, estimated. Discharge estimates 

below 160 second-feet, July to November, 1907, and July to September, 1908, obtained by comparison with 

records of Clackamas and North Fork of Santiam rivers, are subject to large errors and are given merely toshow in a rough way the relatively low flow at low stages at this station compared with other streams 

rising in the Cascade Mountains.

SILETZ KIVEK DRAINAGE BASIN.

GENERAL FEATURES.

Siletz River rises in the mountains in the western part of Polk 

County, at an elevation of about 3,000 feet above sea level, flows 

in a general southwesterly direction to Siletz, in Lincoln County, 

and thence winds tortuously northward and westward until it enters 

the Pacific Ocean through Siletz River Bay, about 6 miles northwest 

of Kernville. Its total length is approximately 50 miles, and its 

drainage area measures about 320 square miles.

Its basin is densely timbered throughout, although some areas of 

logged-off lands may be found on the lower reaches of the stream.

The mean annual rainfall at the mouth of the river is 75 or 80 

inches; at the headwaters it is undoubtedly as high as 150 inches. 

The annual run-off shows about 9 second-feet per square mile of 

drainage area. The records thus far show very little variation in 

the total run-off of this drainage area, but it is probable that 1905 

would be classed as a dry year, and that 1910 may safely be considered 

a wet year.
592 SURFACE WATER SUPPLY OP OREGON, 1878-1910.

SILETZ RIVER AT SILETZ, OREG.

Location. In sec. 9, T. 10 S., R. 10 W., about 1 mile above the ferry at Siletz, 6 

miles below Rock Creek, and about 9 miles north of Toledo, the nearest railroad 

point.

Records presented. November 26, 1905, to September 30, 1910.

Drainage area. 220 square miles.

Gage. Staff in two sections; lower section inclined, upper section vertical.

Channel. Coarse gravel and sand; shifting.

Discharge measurements. Made from a cable at the gage prior to fall flood of 

1909; since then by wading, as equipment was destroyed.

Accuracy. Estimates good.

UMPQUA RIVER DRAINAGE BASIN.

GENERAL FEATURES.

Umpqua River is formed by the junction of North Umpqua and 

South Umpqua near the city of Roseburg in Douglas County, Oreg. 

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 Umpqua 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 agricultural 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 elevation at Roseburg is 485 feet above sea level. The North Umpqua 

falls over 3,600 feet in the 75 miles from Diamond Lake to Roseburg 

by the river channel. The lower portion of the Umpqua has comparatively little fall, as is evidenced by the very winding character 

of the stream.

The region is one of the most densely forested in 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 individuals.

The mean annual rainfall 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 SUEFACE 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 possibilities 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 difficult 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.

NOTE. Daily discharge determined as follows:

1905 to 1908. From rating curves well denned between 1,200 and 10,000 second-feet, and fairly well denned 

to 20,000 second-feet. Discharge estimated Nov. 3-18 and Dec. 17,1905. Discharges in August, September, 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.

1909. 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 basin1910. 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.

water in the spring of 1910. but some of it remained and affected the discharge relation during the summer

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 

unite 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:

Big Butte Creek (drainage area, 268

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 dram 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 Mount Pitt) a snow-capped peak 

dividing the drainage of Big Butte and Little Butte creeks. The general 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.

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 operation. A number of little ditches are used to irrigate the narrow valley 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 will not be utilized in the most economic 

manner 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 Valley 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-power development. At 

present the only important plants are those of the CaliforniaOregon 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.

KLAMATH RIVER DRAINAGE BASIN.

GENERAL FEATURES.

Klamath River drains, a territory lying east of the Cascade Range 

in south-central Oregon and south of the Siskiyou Mountains in California. 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 \ 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 Klamath Falls is 4,100 feet.
656 SURFACE WATER SUPPLY OF OREGON, 1878-1910.

The principal tributaries of Klamath River are WUliamson 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. i sec. 7, T. 32 S., E. 9 E., at lower extremity of Klamath 

Marsh, at point locally known as Rocky Ford, 13 miles northeast of Klamaih 

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. October 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.

NOTE. Daily discharge determined from two fairly well defined rating curves, one applicable for 1908, 

and the other for 1909 and 1910. Measurement made in 1910 probably not reliable. Discharge for January 

and February, 1910, reduced by varying amounts to allow for effect of ice, as indicated by the observers 

notes. Discharge interpolated for days on which gage was not read

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. 

G-age. 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.

LINK BIVEB, AT KLAMATH FALLS, OREGK

Location. In sec. 32, T. 38 S., R. 9 E., at the county bridge over Link River at 

Klamath Falls, 1J 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 diversion. 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 BIVEB DRAINAGE BASIF. 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, backwater 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.

KLAMATH BIVBB DEAINAGE BASIN. 703

LOST RIVER AT OLENE, OREG.

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

NOTE. Daily discharges determined as follows: From two fairly well denned rating curves applicable 

July 16, 1904, to May 17,1906, and May 18 to Dec. 31, 1906; 1907, by indirect method for shifting channel. 

Discharge not computed after May 31,1907, as records at Olene are almost directly comparable with those 

at Merrill and are much more reliable.

TITLE LAKE NEAR MERRILL, 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.

Cooperation. Station maintained by the United States Reclamation Service since 

May, 1909; records prepared for publication by engineers of United States Geological Survey.

MILLER CHEEK NEAR LORELLA, OREG.

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.

NOTE. Creek dry June 17 to Dec. 31,1905, July 7 to Nov. 17,1906, July 18 to Oct. 25,1907, and July 1 to 

Nov. 10,1908. During the winter stream freezes over at gage but not at the riffle control, so discharge 

relation is not materially affected by ice. Low gage heights Jan. 9-20,1910, may be due to effect of low 

temperature on Bristol gage and not to low discharge.
KLAMATH RIVER DRAINAGE BASIN. 723

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 California, 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 valley 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, Cottonwobd 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 Valley Irrigation Co. for the reclamation of 40,000 acres of land in the Goose
728 STJEFACB WATEE SUPPLY OF OBEGON, 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 Cottonwood Creek. The flow of Cottonwood Creek is well maintained 

throughout the year, but Drews Creek is more flashy.

COTTONWOOD CREEK NEAB 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. 

G-age. 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.

DREWS CHEEK NEAR LAKEVIEW, OREG.

Location. In sec. 4, T. 40 S., R. 18 E., 1 mile below the Drews Creek dam, 13 miles

southwest of Lakeview.

Records presented. January 16, 1909, to September 30, 1910. 

Drainage area. 211 square miles. 

Gage. Vertical staff at highway bridge installed March 1, 1910. Two gages had

previously been used inclined staff at station No. 1, at the dam site, January 16

to May 31, 1909, and vertical staff at station No. 2, at a dump-car bridge 100 feet

below the dam site, November 20, 1909, to February 28, 1910. 

Channel. Gravel; not likely to shift; at highest stages stream overflows into a

second channel.

Discharge measurements. Made from a wagon bridge near the gage or by wading. 

Winter flow. Winters are severe at this station, but the flow is so small that very

little error is introduced in the estimates as a whole. 

Accuracy. Records subject to considerable error on account of diurnal fluctuation.

Present conditions favorable for good results; conditions at station No. 2 were

very poor. 

Cooperation. This station is maintained by the Goose Lake Valley Irrigation Co.

NOTE. Daily discharge computed by engineers of United States Geological Survey, chiefly from data 

furnished by'the Lakeview Irrigation & Power Co. Discharge Jan. 1-15,1909, estimated by comparison 

with records of Cottonwood Creek. Discharge Jan. 16 to May 31,1909 (station No. 1), determined from 

rating curve well defined between 100 and 900 second-feet. Discharge Nov. 20 to Dec. 3,1909 (station No. 2), 

determined from a curve fairly well defined between 500 and 1,200 second-feet; uncertain below SOOsecondfeet; discharge Dec. 4,1909, to Feb. 28,1910 (station No. 2), obtained from acurve fairly well defined between 

70 and l,500second-feet; approximate below 50 second-feet. Discharge Mar. 1 to Sept. 30,1910, determined 

from a rating curve well denned below 1.200 second-feet. Daily discharge for days on which gage was not 

read interpolated or roughly estimated from the record of discharge of Cottonwood Creek. No correction 

for effect of ice.

GREAT BASIN DRAINAGE IN OREGON.

GENERAL FEATURES.

In Oregon, as in other parts of the Great Basin, 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 insufficient, 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 elevation 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 called 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 Greek. All three are used more or less for irrigation, and 

any additional development will require construction of storage reservoirs 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.

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 referred to the present gage have been reduced to the same datum.

Channel. Bowlders and gravel; probably shifts slightly.

Discharge measurements. Made from highway bridge or by wading^
WABNER 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. 

Cooperation. Station maintained in cooperation with Warner Lake Irrigation Co.

NOTE. Readings for March and April made at the bridge (lower) gage; those beginning in June at the 

upper gage. 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.

NOTE. Daily discharge determined as follows: Mar. 1 to 10, from a fairly well defined discharge rating 

curve; Mar. 11 to 23, by indirect method for shifting channels; Mar. 24 to Apr. 19, from a poorly defined 

curve; Apr. 20 to June 2, by means of a hydrograph drawn through the measurement of May 19 and following the rise and fall of Deep Creek near Adel; June 3 to Sept. 15, from a curve well defined above 5 

second-feet; Sept.16 to 30, from a rating curve well denned (by measurement of Sept. 30,1910, and measurements in 1911) between 3 and 600 secoad-feet.

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 fluctuation.

WAENEB LAKE DRAINAGE BASIN. 73$

DEEP CHEEK 1 AT ABEL, OREG.

Location. In the SE. £ NW. J 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 February 23, 1910, by the Warner Lake Irrigation Co. was at times affected by backwater from temporary dam below.

Channel. Probably permanent; bed of stream composed of gravel and stone.

Discharge 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. Measurements of the combined discharge showed 25 second-feet of water in June, 1910; 20 

second-feet in April, 1911; IS 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 difficult during 

the spring by diurnal fluctuations, which, however, are not so marked as on 

Twenty-mile and Honey creeks.

Cooperation. Station maintained in cooperation with the Warner Lake Irrigation 

Co.

NOTE. Ice probably existed Dec. 2 to 31,1909.

Discharge relation probably affected by ice Jan. 2-9,1910. Gage carried out by flood and ice Jain Jan. 23 

and replaced by observer Feb. 8. Creek somewhat obstructed by ice Feb. 8 to 14, after which obstruction not 

probable. Gage heights Feb. 28 to Mar. 2 are the mean of several readings a'day. The highest stage reached 

was 9.0 feet at 6 p. m. Mar. 2. Subsequent readings were made about noon each day, when the creek was 

at about its lowest stage in the diurnal cycle, and are therefore not fairly representative of the daily mean.

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 denned 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, 

19iO, determined from a rating 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 nigh water; Feb. 8-13, estimate reduced on account of ice; Mar. l-io, 

discharge taken from a hydrograph drawn by plotting as coordinates with time the discharge corresponding to gage readings on the upper gage and the measurements made by engineers of the Warner Lake Irrigation 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.

The maximum discharge recorded, 4,950 second-feet, at 6 p. m. Mar. 2,1910.

WARNER LAKE DRAINAGE BASIN. 743

HONEY CREEK NEAR PLUSH, OREG.

Location. In the SW. J sec. 20, T. 36 S., R. 24 E., half a mile above the mouth of

the canyon, 1J 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. 

Gages. 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

aboAre 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.

NOTE. Stream frozen over Dec. 7, 1909. 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 hydrograph 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 gelation. Gage heights beginning Mar. 6 represent 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.

NOTE. Daily discharge Feb. 24 to July 31 determined from a fairly well-defined discharge rating curve.

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 determinations 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.

Daily discharge for high-water period in January determined by assuming a discharge of 30 secondfeet 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.

Mean discharge for Feb. 1-23 estimated at 30 second-feet.

Daily discharge July 17 to Sept. 30 estimated at 1.5 second-feet.

MISCELLANEOUS STATIONS IN WARNER VALLEY.

A number of gaging stations were established by the Warner 

Lake Irrigation Co. in June, 1910, on Deep and Honey Creeks and 

their tributaries and records obtained for about six weeks. The 

records of the measurements and gage heights have been furnished 

by the company, but discharges have been computed by the United 

States Geological Survey.

ALBERT LAKE DRAINAGE BASIN. 

GENERAL FEATURES.

Abert Lake is a strongly alkaline body of water lying near the central 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, OREG.

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 flow. Affected by ice.

Diversions. The station is above all diversions except George Conn's irrigation 

ditch, which heads about 2J 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 backwater was noticeable prior to 1910. During 1910 there was probably a little backwater. The Brattain ditch diverts water about 300 feet below the gage on the 

right bank; it follows the foothills for many miles down 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 201 

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.

Accuracy. Estimates good.

756 SURFACE WATER SUPPLY OF OREGON, 1878-1910. 

SUMMER LAKE DRAINAGE BASIN. 

GENERAL FEATURES.

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 agricultural 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.

ANA RIVER NEAR SUMMER LAKE, OREG.

Location. In the NW. \ SE. \ sec. 6, T. 30 S., R. 17 E., about 6 miles northwest 

of the town of Summer Lake.

Records presented. Occasional Jaeasurements July 17, 1904, to September 25, 

1910.

Drainage area. Undetermined.

Gage. Vertical staff.

Channel. Clay; practically permanent.

Discharge measurements. Made from foot log near the gage or from county bridge.

Accuracy. Discharge relation badly affected by backwater from the lake and temporary irrigation dams and gage heights are therefore not published.

This stream is almost entirely fed by springs and its flow is practically constant.

SILVER LAKE DRAINAGE BASIN. 

GENERAL FEATURES.

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 southeastward 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 comprising 300,000 acres. This valley has no surface streams, but contains two or three small lakes. Alkali Flat, near the northeastern
758 SURFACE WATER SUPPLY OP 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 portion 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., 1J 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 appropriated 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. Records probably reliable.

NOTE. Daily discharge determined from rating curves applicable as follows: 1905, fairly well defined: 

1906, well defined above 50 second-feet; 1907 to 1910. fairly well defined. Open-channel rating curve applied 

throughout the years 1905 and 1906; values for the winter months probably somewhat too large. The 

following estimates and corrections have been made: Jan. 1-16,1909, discharge estimated 30 second-feet; 

gage heights Dec. 16,1909, to Feb. 1,1910, reduced 0.2 foot before applying rating curve, to allow for obstruction of channel by ice. Discharge Feb. 2-8 interpolated on account of ice jam.

NOTE. Daily discharge for periods of unobstructed channel determination from a curve fairly well 

defined between 4 and 50 second-feet, but uncertain above on account of the lack of high-water measurements during winter floods.

Due allowance has been made for backwater caused by a temporary dam below the gage for the following periods: Apr. 18 to July 20,1905; Apr. 19 to June 30,1906; 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 in, the fall when it is removed, 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. 16-31,1905; Jan. 1 to Mar. 20,1906; Dec. 19-31,1909; Jan. 1 to Feb. 24 and Dec. 19-31,1910.

Discharge estimated July 20-31,1906, Jan. 1-11,1909, and July 7-31,1910.

MALHETJR AND HARNEY LAKES DRAINAGE BASIN. 

GENERAL FEATURES.

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 OP 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 nearly 700,000 acres 

of flat alluvial soil forming a circular valley surrounding the lakes and 

extending like fingers into the valleys 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 sufficiently 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 Malheur Lake; and Silver Creek, flowing from the northwest into Harney 

Lake. South of Silver Creek, in a flat valley, lies Silver Lake, a small 

playa 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 Steens 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.

Silvies 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.
MALHEUB AND HARNEY LAKES DRAINAGE BASIN. 775

Silver Creek heads in a spur of the Blue Mountains and 'flows 

southeastward through Silver Creek Valley 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 hi summer 

its flow practically ceases.

Between Silvies River and Silver Creek and flowing hi the same 

general direction is Sagehen Creek, a small stream heading hi 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 run of Harney Valley is broken by a low pass known 

as Malheur Gap. Through this gap a drainage canal could be excavated 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 hi to 

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. Accordingly an injunction was issued restraining the company from building the project.

MALHEUR LAKE AT NARROWS, OREG.

Location. In sec. 26, T. 26 S., R. 31 E., at the highway bridge across the channel 

connecting Malheur and Harney lakes, a few hundred feet north of Narrows.

Records presented. May 14,1903, to July 21, 1906, and September 4-8, 1909.

Gage. Vertical staff on highway bridge. The datum of this gage was 8.20 feet when 

installed in 1903, referred to a bench mark at the east end of the bridge, elevation 

4,088 feet. Gage is on a relatively narrow portion of a section of Malheur Lake.

NOTE. Gage height 1.40 represents surface of dry bed. From about Sept. 1, 1903, water at gage was 

disconnected from Malheur Lake and subsequent records do not agree with fall of lake surface until some

time in 1904.

SILVLES RIVER NEAR SILVIES, 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 1J 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.

NOTE. Daily discharge determined from three fairly well defined rating curves, applicable 1903,1904, 

and 1909-10; discharge Jan. 1-14,1909, estimated because of ice; discharge Jan. 15 to Feb. 16,1909, derived 

from open-channel curve, compared with discharge at Burns station, where there was little ice, and reduced 

40 per cent. Mean discharge Jan. 1 to Feb. 25, 1910, estimated at 30 second-feet; discharge determined 

from open-channel curve Feb. 26-28 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.

a Estimated on account of probable ice obstruction. 6 Estimated.

SILVIES EIVER NEAR BUENS, OEEG.

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 September 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 

alluvial 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, 1878-1910.

Discharge measurements. Made from a cable at Hampshire'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 Valley. As even the flood discharge is so used, any irrigation project that would require the diversion of the water would involve the settlement of accrued water rights.

Accuracy. Conditions unfavorable for accurate determination of discharge.

a Estimated.

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 September, 1910, estimated by comparison with records derived from observations at other stations and by assuming 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 approximate 

estimate of the total yearly discharge.
MALHEUR AND HARNEY LAKES DRAINAGE BASIN. 793

DONNER UND BLITZEN RIVER NEAR DIAMOND, OREG.

Location. In sec. 8, T. 32 S., R. 32J E., at wagon bridge near "P" ranch buildings, 

about 23 miles southwest of Diamond.

Records available. January 27,1909, to July 31, 1910.

Drainage area. 200 square miles.

Gage. Vertical staff just below bridge.

Channel. Gravel and sand; practically permanent; banks covered with underbrush and subject to overflow.

Discharge measurements. Made from bridge or by wading.

Winter flow. Affected by ice.

Diversions. Five ditches divert water above the station and about 300 feet below a 

brush and rock dam diverts water into a sixth ditch. No record has been kept of 

the actual time of operation of these ditches.

Accuracy. Owing to changes in the diversion dams and lack of accurate information 

of diversions, estimates can only be considered fair.

Cooperation. Maintained in cooperation with the William Hanley Co.

NOTE. Gage heights from about Jan. 24 to Feb. 7,1910, increased by effect of a driftwood jam on a riffle 

below. A dam about a mile below the gage, used to divert water into a canal, was raised prior to the 

measurement on May 21, probably some time in March or April.

Relation of gage height to discharge probably not affected by ice.

Aug. Sept.

NOTE. Daily discharge determined as follows: Feb. 1. 1909, to Mar. 20, 1910, from fairly well defined 

rating curves; Mar. 21 to July 30.1910, from poorly defined curve. From July to September, 1909, and perhaps for a longer period, gage heights were anected by a dam below the gage; the stability of this dam and 

its exact period of operation are uncertain. Mean discharge Nov. 21-27,1909, estimated at 200 second-feet. 

Discharge estimates arbitrarily reduced Jan. 24 to Feb. 7,1910, to allow for effect of wood jam.

MALHEUR AND HARNEY LAKES DRAINAGE BASIN. 801

SILVER CREEK NEAR RILEY, OREG.

Location. In eec. 30, T. 22 S., R. 26 E., 12 miles above Riley, 3 miles below the 

junction with Nichols Creek.

Becords 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. 

When the station was reestablished in 1909 a new gage was installed on the right 

bank.

Channel. -Clean gravel; not likely to shift. 4

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 which 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 agricultural lands on both sides of the stream.

Accuracy. Results at this station are only approximate.

Discharge measurements of Silver Creek near Riley, Oreg., in 1903-1910.

NOTE. Creek frozen Nov. 14-20 and Dec. 4-11,1909. Creek dry Aug. 3 until about Oct. 1,1910. Discharge relation somewhat affected by backwater from a dam below; observer notes changes in dam Apr. 

23 and May 20,1910, which no doubt caused the increase in stage on those days.

Daily discharge, in second-feet, of Silver Creek near Riley, Oreg.,for 1904-1906, 1909-10.
