SURFACE WATER SOPHS Of PACIFIC SLOPE BASINS IN OREQON AID LOWER COLOMBIA 

RCTBR BASH. 1947

aeon or WORK

This volume is one of a series of 14 report* presenting results of measurements of 

stage and flow made on streams, lakes, and reservoirs in the United States during the 

water year ending September 30, 1947. The work was begun in 1886 in connection with 

special studies relating to irrigation. Measurements of the flow of streams and of the 

stage and contents of lakes and reservoirs have been made at about 11,100 gaging stations 

in the 48 States and also at many in the Territories of Alaska and Hawaii. In July 1947, 

5,810 gaging stations, Including those in Hawaii, were being maintained by the Geological 

Survey and cooperating organizations. Miscellaneous discharge measurements were made 

during the water year at many other points.

In the execution of the work many State and private organizations have cooperated, 

either by furnishing data or by assisting in collecting data. Cooperation of the first 

kind is acknowledged in connection with the description of each station affected; cooperation of the second kind is acknowledged, under the heading "Cooperation," in the introductory matter that precedes the gaging-station records in each volume. In the present 

volume, the section on cooperation of the second kind appears on page 12.

DEFINITION OF TERMS

The units in which stream-flow data are presented in this report and other terms used 

herein are defined as follows:

 Second-feet" is an abbreviation for "cubic feet per second." A second-foot is the 

rate of discharge of a stream whose channel is 1 square foot in cross-sectional area and 

whose average velocity is 1 foot per second.

 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 runoff is distributed uniformly both as regards time and area.

 Runoff in inches" is the depth to which an area would be covered if all the water 

draining from it in a given period were uniformly distributed on its surface. It is used 

for comparing runoff with rainfall,-which is usually expressed in Inches.

An "acre-foot" is the quantity of water required to cover an acre to the depth of 

1 foot and is equivalent to 43,560 cubic feet. The term is commonly used in connection 

with storage for irrigation.

"Second-foot-day" is the volume of water represented by a flow of 1 second-foot for 24 

hours. It is equivalent to 86,400 cubic feet, 1.983471 acre-feet, or 646,317 gallons and 

represents a runoff of 0.0372 inch from 1 Square mile.

"Stage-discharge relation" is an abbreviation for the term "relation between gage height 

and discharge."

"Control" is a term used to designate a feature downstream from the gage that determines the stage-discharge relation at the gage. This feature may be a natural section, 

a reach of the channel, or an artificial structure.

2 SURFACE WATER SUPPLY. 1947, PART 14

"Contents" is a term applied to the volume of water in a reservoir. It is computed on 

the basis of a level pool and does not include bank storage unless otherwise indicated.

EXPLANATION OF DATA

The base data collected at gaging stations consist of records of stage, measurements 

of discharge, and general information used to supplement the records of stage and discharge 

measurements in determining the daily flow. The records of stage are obtained either from 

direct readings on a nonrecording gage or from a water-stage recorder that gives a continuous record of the fluctuations. Measurements of discharge are made with a current 

meter by the general, methods outlined in standard textbooks on the measurement of river 

discharge. Typical structures in use at gaging stations are shown in figure 1.

Rating tables giving the discharge for any stage are prepared from the discharge measurements The application of the daily mean gage height to those rating tables gives the 

daily mean discharge, from which the monthly and the yearly mean discharge are computed. 

If the stage-discharge relation is subject to change because of frequent or continual 

change in the physical features that form the control, the daily mean discharge is determined by the "shifting-control method," in which correction factors based on individual discharge measurements and notes by engineers and observers are used in applying the 

gage heights to the rating tables. At times the stage-discharge'relation for a station 

may be temporarily changed by the presence of aquatic growth or debris on the control. 

For such times the daily mean discharge is computed by what is essentially the "shiftingcontrol" method, described above.

*

At some gaging stations the stage-discharge relation is affected by backwater from 

reservoirs, tributary streams, or other sources, which necessitates the use of the "slope 

method," in which the slope or fall in a reach of the stream is a factor in the determination of discharge. Information requisite for determining the slope or fall is obtained 

by means of an auxiliary gage set at some distance froa the base gage. At some stations 

the stage-discharge relation is affected by changing stage, and for them the rate of 

change of stage is used as a factor in the determination of discharge.

At most gaging stations in the northern part of the United States and at some in the 

mountainous regions of other parts the stage-discharge relation is affected by ice during 

the winter, which makes it impossible to compute the discharge in the usual manner. Discharge for periods of ice effect is computed on the basis of the gage-height record and 

occasional winter discharge measurements, consideration being given to the available Information on temperature and precipitation, notes by gage observers and engineers, and 

comparable records of discharge for stations in the same or nearby basins. For those 

stations at which the stage-discharge relation is affected by ice, the days included in 

the periods of ice effect either are indicated in the table by symbols referring to a 

footnote that states this fact or are given In a general note following the table. The 

days on which discharge measurements were made during or between periods of ice effect, 

shortly before the first period, or shortly after the last period are similarly indicated 

by a footnote.

For most of the gaging stations on streams in the area covered by this report the data 

presented comprise a description of the station, a table showing the daily discharge of

the stream, and a table of monthly and yearly discharge and runoff. Skeleton rating 

tables are published for all stations except those at which the daily discharge for the 

greater part of the year was determined by the shifting-control method, the slope method, 

or other special methods.

The description of the station gives the type of gage, its latitude and longitude as 

determined from the best available maps, and information in regard to diversions that 

decrease the flow at the gage, artificial regulation from pondage or storage, and the 

accuracy of the records. Under "Average discharge" is given the average discharge for the 

number of years indicated. It is given only for stations for which there are 10 or more 

complete years of record. Under "Extremes" are given the maximum discharge and gage 

height; the minimum discharge if there is little or no regulation; the minimus daily discharge if there is extensive regulation (also the minimum discharge if useful); and the 

mlnimua gage height (unless it is of no importance). Unless otherwise qualified, the 

maximum discharge corresponds to the crest stage, obtained by use of a water-stage 

recorder or a nonrecording gage read at the time of the crest. Likewise the minimum discharge represents the lowest stage, unless otherwise qualified. Selected peak discharges 

with the times of their occurrence are given, below the table of monthly discharge, for 

some stations. This supplementary information is generally omitted for a station at which 

the drainage area of the stream is less than 10 or more than 10,000 square miles or at 

which, on most days, the peak discharge exceeds the mean discharge by less than 10 percent

For stations equipped with water-stage recorders, except those on streams subject to 

sudden or rapid fluctuation, the table gives the discharge corresponding to the daily mean 

gage height. For stations subject to such fluctuation the dally mean gage height may not 

indicate the true daily mean discharge, which must be obtained by averaging the discharge 

for parts of the day or by using the discharge Integrator, an instrument for obtaining the 

daily mean discharge from a continuous gage-height graph and containing as an essential 

element a curve representing the stage-discharge relation at the station. For stations 

equipped with nonrecording gages, the table of daily discharge gives the discharge corresponding to either once-daily readings of the gage, the mean of twice-daily readings, or 

the mean gage height determined from gage-height graphs based on gage readings. For 

periods of rapidly changing stage, the dally mean discharge is determined from gage-height 

graphs based on gage readings, the frequency of which is stated in the station description.

In the table of monthly discharge the column headed "Second-foot-days" gives the sum 

for each month of the figures given in the table of daily discharge. The column headed 

"Maximum" gives the maximum daily discharge, not the momentary discharge when the water 

.surface was at crest stage. Likewise, in the column headed "Minimum" the quantity given 

is the minimum daily discharge. The column headed "Mean" gives the average flow in cubic 

feet per second during the month.

For most gaging stations on lakes and reservoirs the data presented comprise a description of the station and a monthly summary table of stage and contents. For some reservoirs a table showing daily contents is given. A skeleton table of capacity at given 

stages is usually given in the first report in which data for a station are published 

but is omitted from succeeding reports.
SURFACE WATER SUPPLY, 1947, PART 14 5

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream-flow data depends primarily on (1) the permanency of the stagedischarge relation or, if the control is unstable, the frequency of discharge measurements 

and (2) the accuracy of observations of stage, measurements of flow, and interpretation of 

records.

The station description gives a statement in regard to the general accuracy of the 

records. "Excellent" indicates that, in general, the error in the daily records is 

believed to be less than 5 percent; "good," less than 10 percent; "fair," less than 15 percent; and "poor," probably more than 15 percent. The records of monthly and yearly mean 

discharge and runoff are, in general, more accurate than the daily records.

Yield at some stations as indicated by monthly means may vary widely from natural yield, 

owing to diversion, consumption, regulation by storage, increase or decrease in evaporation 

due to artificial causes, or other factors. For such stations figures of "second-feet per 

square mile" and "runoff in inches" are not published unless storage or diversion records 

are included indicating the extent of the regulation or diversion or unless satisfactory 

adjustments can be made for changes in contents or reservoirs or for other changes incident 

to use and control. Evaporation from a reservoir is not included in the adjustments for 

changes in reservoir contents, unless its inclusion is Indicated. Even at those Stations 

where adjustments are made, in some instances large errors in computed yields may occur 

when relatively large negative adjustments are applied or when evaporation is large in 

comparison with the observed discharge. Figures of second-feet per square mile and 

runoff in inches are also omitted if the drainage area includes large noncontributing 

areas or if the average annual rainfall over the drainage area is less than 20 inches.

Many gaging stations on streams in the irrigated areas of the United States are situated above most of the diversions from those streams, and therefore the discharge recorded 

does not show the water supply available for further development, as prior appropriations 

below the station must first be satisfied.

The table of monthly discharge presents in summary the distribution of the flow past the 

station. The table of daily discharge affords opportunity for more detailed studies of the 

variation in flow. As further observations in each succeeding year may be expected to 

throw new light on data previously published, it should be borne in mind that such data are 

subject to revision in succeeding water-supply papers.

PUBLICATIONS

Papers on surface water supply containing records from 1899 to date, grouped by years 

and drainage basins, are listed by number on page 8. The data for any particular gaging 

station will, in general, be found in the reports covering the years during which the 

station was maintained. For example, the data for 1910 to 1920 for any station in the 

area covered by part 3 are published in Water-Supply Papers 283, 303, 323, 353, 403, 433, 

453, 473, and 503, which contain records for the Ohio River Basin for those years.

The records at most of the stations discussed in these reports extend over a series of 

years. Miscellaneous measurements at many points other than regular gaging stations have 

been made each year and are published under "Miscellaneous discharge measurements" at the 

end of each report, the streams and points of measurement listed appearing in the same 

relative order as the streams and gaging stations in the body of the report. An index of 

the records obtained prior to 1904 has been published in Water-Supply Paper 119.

Each of the reports on surface water supply for the year 1939, issued as Water-Supply 

Papers 871 to 884 (see table on p. 8), contains, for the area covered by that report, a 

summary of yearly discharge at gaging stations at which 10 or more complete years of record 

have been collected. These summaries are available also as separate reprints.

collected during the systematic operation of gaging stations. Detailed information on 

the stage and discharge of many streams during major floods has been included in special 

reports on these floods published by the Geological Survey. The more recent of these 

special reports also contain other pertinent hydrologic information and analyses and compilations of data relating to earlier noteworthy flooSs. The following list gives the numbers and titles of these reports:

Survey.

Note.- Records through 1936 collected by the Oregon State engineer (some of them in cooperation 

with the Bureau of Reclamation of the 0. S. Department of Interior) are contained in the bulletins 

published by that officer. (See p. 9 "State reports containing compilation of records of discharge.") The other records listed In this table have not been published.

COOPERATION

In Oregon the work was done under cooperative agreements with the State of Oregon, 

Charles E. Strlcklln, State engineer; Umatllla County Court; and the cities of Corvallls, 

Eugene, McMinnvllle, and Portland. In Washington the work was done under cooperative 

agreements with the State Department of Conservation and Development, Art Garton, director, 

and Charles J. Bartholet, consulting engineer for the department; Columbia County; and 

Walla Walla County.
DIVISION OF WORK 13

Financial assistance was furnished by the Corps of Engineers for the operation of 39 

gaging stations in Oregon and 15 in Washington.

Financial assistance was also furnished by the Bureau of Reclamation of the United 

States Department of Interior.

Assistance in collecting records was rendered by the following organizations:

Oregon: Counties of Crook, Deschutes, Jackson, Jefferson, Josephine, Klamath, 

and Umatilla; city of Grants Pass; The California Oregon Power Co., California 

Public Utilities, Pacific Power & Light Co., and Portland General Electric Co. 

Washington: Northwestern Electric Co. and Pacific Power & Light Co.

DIVISION OF'WORK

The stream-gaging work was conducted by the water resources division of the Geological 

Survey Carl G. Paulsen, chief hydraulic engineer and Joseph V. B. Wells, chief of the 

surface water branch. The data for the gaging stations were collected and prepared for 

publication under supervision of district engineers as follows: In Oregon, G. H. Canfield, 

the work being done in collaboration with Charles E. Stricklin, State engineer; in 

Washington, F. M. Veatch.

The records were reviewed and the manuscript prepared for publication under the direction of B. J. Peterson, chief, annual reports section.

COLUMBIA RIVER MAIN STEM 

Columbia River near The Dalles, Oreg.

Location.- Water-stage recorder, lat. 45°39', long. 120°58', in NE^ sec. 20, T. 2 N., R. 

ib &., just upstream from Celilo Falls, 3 miles downstream from Deschutes River, and 

11 miles east of The Dalles. Datum of gage is at mean sea level, datum of 1929.

Drainage area.- 237,000 square miles.

Records available.- June 1878 to September 1947. Prior to October 1931, records based 

on starr gage at The Dalles, supplemented for a few short periods by gage-height 

records at Umatllla and Cascade Locks.. Maximum stages for each year in period 1858 to 

1877 from readings of gage at Lower Cascades Landing.

Average discharge.- 69 years, 194,000 second-feet.

Extremes.- Maximum discharge during year, 542,000 second-feet May 11 (elevation, 142.91 

reet); minimum, 79,700 second-feet Nov. 18 (elevation, 129.15 feet).

1858-1947: Maximum'discharge, 1,240,000 second-feet (-revised) June 6, 1894 (elevation, 106.5 feet on gage at The Dalles. 160.1 feet at present site); minimum observed, 

35,000 second-feet Jan. 12, 1937 (elevation, 126.0 feet).

Remarks.- Records excellent. Storage and diversions for irrigation are only a small part 

or total runoff. Some regulation by Franklin D. Roosevelt Lake above Grand Coulee Dam 

during year, the total increase in contents during the year ending Sept. 30, 1947, being 

65,600 acre-feet.

Cooperation.- Recorder inspected and gages read by Corps of Engineers.

Revision.- Discharge for water year 1894, including revised figures of daily discharge for 

period May 22 to June 12, superseding those published in Water-Supply Paper 370, are 

given herein.

7 H., K. 36 E., 1 mile downstream from point of diversion from Mill Creek and 1 mile 

east of Walla Walla.

Records available.- April 1941 to September 1947.

Extremes (regulated).- Maximum discharge during year, 318 second-feet Jan. 23 (gage 

height, v.'fd reet); minimum, 6.4 second-feet Dec. 6 (gage height, 0.70 foot).

1941-47: Maximum discharge not determined, occurred June 7, 1941 (gage height, 

4.00 feet); minimum, 2.4 second-feet Sept. 16, 1941 (gage height, 0.50 foot), but may 

have been less during period of ice effect Jan. 1-24, 1942.

.September 1936 at present site (incomplete) in reports of State engineer; October 

1936 to September 1945 (unpublished) in files of State engineer.

Average discharge..- 15 years (1929-30, 1931-32, 1933-41, 1942-47), 17.7 second-feet.

Extremes.- Maximum .discharge during year, 222 secpnd-feet Feb. 12 (gage height, 2.46

reet), from rating curve extended above 130 second-feet; minimum observed, 0.3 secondfoot Aug. 27, Sept. 3.

1921-47: Maximum discharge, 1,600 second-feet Jan. 28, 1942 (gage height, 7.91 

feet), from rating curve extended above 300 second-feet; no flow at times.

Remarks.- Records good except those below 5 second-feet, which are fair, and those for 

periods of ice effect or no gage-height record, which are poor. No regulation. Small 

diversions above station for irrigation; for about 20 days each year not over 30 second-feet may be diverted into headwaters of Butter Creek-from Pivemile Creek, a tributary of Camas Creek in John Day River Basin.

36 UMATILLA RIVER BASIN

Principal diversions from Umatllla River between Pendleton and Umatllla, Oreg.

The following canals divert water from Umatllla River between Pendleton and Umatllla: 

Furnish Canal, from right bank of Umatllla River in sec. 36. T. 3 N., R. 29 E., Umatilla 

project feed canal, from right bank of Umatilla River in SWt sec. 22, T. 3 N., R. 29 h., 

to feed Cold Springs Reservoir of Bureau of Reclamation. Western Land Canal, from left 

bank of Umatilla River in NEi sec. 21, T. 3 N., R. 29 E.; gage is 1 mile downstream from 

intake. Alien Canal, from right bank of Western Land Canal, half a mile downstream from - 

head gate of that canal. Maxwell Canal, from right bank of Umatilla River In SWu sec. 28, 

T 4 N , R 28 E.; at times it receives water from Cold Springs Reservoir. West Division 

main canal, from left bank of Umatilla River in SW£ sec. 28, T. 5 N., R. 28 E. Brownell 

Canal, from right bank of Umatilla River, 2 mi!4s below West Division main canal diversion 

and I? miles above mouth of Umatilla River.

Water diverted by all these canals is used for irrigation of lands on both sides of 

Umatilla River near and below Echo, except that diverted by West Division main canal, 

which is applied to lands along Columbia River in vicinity of Irrigon.

Several smaller canals also divert water between Pendleton and Umatilla, but no records 

for them were obtained.

Records of monthly discharge of the canals, published as a group, are available from 

March 1926 to September 1947; records for some of the canals published separated prior to 

1926.

which are good; records of diversion to Coyote Creek poor. A few small diversions above 

station. Several second-feet diverted around station to Coyote Creek channel through 

24-Inch concrete pipe 600 feet long, several hundred feet upstream. Record for this diversion based on weir measurements at Intake and stage at recorder and on Long Tom River 

below Fern Ridge Dam, except those for Apr. 15 to June 1, July 15-27, which were Interpolated, or computed on basis of field estimates. Fern Ridge Dam, 1,000 feet above 

station, was completed In 1941, and has regulated flow since Nov. 13, 1941 (see preceding page).

a Hr> gage-height record; discharge computed on basis of records for North Santiam River above 

Mayflower Creek, near Detroit, and Little North Santiam River near Mehama.
148 WILLAMETTE RIVER BASIN

Santiam River at Jefferson, Oreg.

Location.- Water-stage recorder, lat. 44°42'50", long. 123°00'40", in SE£ sec. 11, T. 10 

S., R. 3 W., in Jefferson, 350 feet upstream from railroad bridge, 2 miles downstream 

from confluence of North Santiam and South Santiam Rivers, and 9 miles upstream from 

mouth. Datum of gage is 199.63 feet above mean sea level, datum of 1929.

Drainage area.- 1,790 square miles.

Records available.- July 1905 to July 1906 (gage heights only), October 1907 to September 

isiti ana October 1939 to September 1947 in reports of Geological Survey. Gage-height 

records collected at same site since April 1904 are contained in reports of U. S. 

Weather Bureau.

Average discharge.- 17 years (1907-16, 1939-47), 7,188 second-feet.

Extremes.- Maximum discharge during year, 116,000 second-feet Dec. 15 (gage height, 21.15 

reetj; minimum, 510 second-feet Oct. 17 (gage height, 1.81 feet).

1905-6, 1907-16, 1939-47; Maximum discharge observed, 161,000 second-feet during 

night of Nov. 22, 1909 (gage height, 18.2 feet, site and datum then in use), from 

curve of relation between gages based on readings from 1940 to 1945, and rating curve 

for gage at present site extended above 109,000 second-feet (corresponding gage height 

at present site, 23.0 feet from curve of relation; minimum observed, 260 second-feet 

Aug. 15-22, Aug. 24 to Sept. 2, 1940 (gage height, -1.00 foot, site and datum then in 

use).

Maximum discharge known, about 202,000 second-feet (revised) Nov. 21, 1921 (gage 

height, 19.5 feet at railroad bridge 350 feet downstream, site and datum in use prior 

to Oct. 1, 1940, corresponding gage height at present site, 24.4 feet from curve of 

relation).

Revisions.- Maximum discharge for the water year 1943 has been revised to 118,000 

second-reet Jan. 1, 1943 (gage height, 21.24 feet), superseding figures published in 

Water-Supply Papers 984 and 1044.

Remarks.- Records good. Salem Canal diverts from North Santiam River at Stayton for 

irrigation and power use; most of this water reaches Willamette River through Mill 

Creek at Salem. Stayton Canal diverts from North Santiam River at Stayton for irrigation of lands near West Stayton; some return flow reaches North Santiam River above 

station. Albany power canal diverts from South Santiam River at Lebanon; return flow 

reaches Willamette River at Albany. No regulation.

Cooperation.- Gage-height record collected in cooperation with U. S. Weather Bureau.

Revisions.- Revised figures of discharge, in second-feet, for the high-water periods in 

tne water years 1908, 1910, 1912, and 1943 are given here. They supersede those 

published in Water-Supply Papers 370, 362, 414, 984, and 1044.

1905-11, 1940-47: Maximum discharge, that of Dec. 15, 1946; minimum, 21 secondfeet Sept. 10, 1944 (gage height, 1.78 feet).

Maximum stage known at present site, 33.5 feet from floodmark, probably on Dec. 29, 

1937 (discharge not determined).

Revisions.- The maximum discharges for the water years 1945 and 1946 have been 

revised to 8,720 second-feet Feb. 8, 1945 (gage height, 27.87 feet) and 12,000 secondfeet Nov. 27, Dec. 29, 1945 (gage height, 29.05 feet), superseding those published in 

Water-Supply Papers 1044 and 1064.

Remarks.- Records good except those for periods of no gage-height record, which are poor. 

A rew small diversions above station for irrigation; no diversion around station. 

Some diurnal fluctuation during periods of low flow caused by millpond above station.

Cooperation.- Gage-height record collected in cooperation with U. S. Weather Bureau.

Revisions.- Revised figures of discharge, in second-feet, for high-water periods in

the water years 1945 and 1946, superseding those published in Water-Supply Papers 1044 

and 1064, are given herewith:

176 WILLAMETTE RIVER BASIN

Tualatin River at Farmington, Oreg.

Location - Staff gage, lat. 45°27'00" long. 122°57'00", in SE-jj sec. 29, T. 1 S., R. 2 W., 

at Highway bridge at Farmington, 7j miles southwest of Beaverton. Auxiliary staff gage 

at highway bridge 65- miles downstream, 1 mile northeast of Soholls. Datim of each gage 

is 100.42 feet above mean sea level, datum of 1929. All discharge measurements made at 

Farmington.

Drainage area.- 568 square miles.

Records available.- October 1939 to September 1947.

Extremes.- Maximum discharge observed during year, 11,000 second-feet Dec. 16 (gage height, 

327F8~feet); minimum discharge observed, 45 second-feet Aug. 22.

1939-47: Maximum discharge observed, 14,500 second-feet Dec. 20, 1941; maximum gage 

height observed, 33.45 feet Dec. 21, 1941; minimum discharge observed, 28 second-feet 

Sept. 13, 14, 1944.

Maximum stage known, about 37 feet at Farmington and 33.4 feet at gage near Scholls, 

Dec. 22 or 23, 1933.

Remarks.- Records fair. Gages read twice daily. For gage heights above 8 feet, discharge 

computed by using fall, as determined by twice-daily readings of auxiliary gage, as a 

factor. Slight regulation by log ponds and dam below Gaston have little effect at this 

station; considerable pondage between this station and station near Willamette. Some 

diversions by pumping for irrigation above station, chiefly at Wapato Lake, near Gaston.

Discharge, in second-feet, water year October 1946 to September 1947

Engineers).

Drainage area.- 710 square miles.

Kecoras available.- July 1928 to September 1947.

Average discnargeT- 19 years, 1,337 second-feet (including flow of Oswego Canal).

.Extremes (river only).- Maximum discharge during year, 8,970 second-feet Dec. 18 (gage 

neignt, ii.ba reet); minimum, 8 second-feet Sept. 17-20.

1928-47: Maximum discharge, 23,300 second-feet Dec. 23, 1933 (gage height, 17.72 

feet, present datum): minimum observed, 2 second-feet Aug. 14-21, 1928 (gage hei^nt, 

1.27 feet, present datum).

Remarks.- Records excellent except those below 50 second-feet, which are good. Oswego 

uanai (p. 181) diverts water 4| miles above station for recreational use in Oswego Lake 

and development of power between outlet of that lake and Willamette River, to which 

water is returned. Several small diversions above station for irrigation. Some regulation in low-water season by flashboards on crest of diversion dam of Oswego Canal.

Datum of gage is 183.04 feet above mean sea level, datum of 1929.

Drainage area.- 43.0 square miles, including two small streams on left bank which enter 

creeK ceiow station.

Records available.- October 1940 to September 1947.

Extremes.- Maximum discharge during year, 1,300 second-feet Feb. 2 (gage height, 12.34 

reet); minimum, 9 second-feet Oct. 12.

1940-47: Maximum discharge, 1,330 second-feet Feb. 6, 1946 (gage height, 12.46 

feet); minimum, 7 second-feet Sept. 10-12, 1944.

Remarks.- Records good except those for periods of shifting control or no gage-height 

record, which are fair. Records include measured or estimated discharge of two small 

streams which flow through dam site at station and enter creek from left bank about a 

mile below station. Probably some pumping for irrigation above station. Diurnal 

fluctuation at low flow caused by log pond upstream.

Records available.- December 1905'to June 1912, October 1923 to September 1926, January 

1942 to September 1947.

Average discharge.- 13 years (19'06-11, 1923-26, 1942-47), 2,419 second-feet.

Extremes.- Maximum discharge observed during year, 19,300 second-feet Dec. 14 (gage 

height, 14.22 feet); minimum observed, 96 second-feet Oct. 1.

1905-12, 1923-26, 1942-47: Maximum discharge, 71,000 second-feet Jan. 4, 1907 

(gage height, 26.0 feet, from floodmark, former site and datum), from rating curve 

extended above 15,000 second-feet parallel to later curve defined by discharge measurements to 24,000 second-feet; minimum observed, 36 second-feet Aug. 12, 13, 1926.

Flood of Feb. .21, 1927, reached a stage of about 31.8 feet, present site and datum 

(discharge, about 78,000 second-feet). Flood of February 1890 reached a stage just 

2 feet higher, according to John Lander who lived nearby at the time of both floods 

(discharge, about 85,000 second-feet).

Remarks.- Records fair except those for period of doubtful or no gage-height record,

which are poor. Gage read twice daily. Many small diversions above station for irrigation; no regulation.

a Ho gage-height record; discharge computed on basis of records for South Umpqua River at Tiller 

and Umpqua River near Elkton.

d Doubtful gage-height record; discharge computed as explained in footnote a.
UMPQUA RIVER BASIN 213

Urapqua River near Elkton, Oreg.

Location.- Staff gage, lat. 43°35', long. 123°33', in sec. 8, T. 23 S., R. 7 W., 4 miles 

soutn of Elkton. Datum of gage is 91.33 feet above mean sea level, datum of 1929.

Drainage area.- 3,680 square miles.

Records available.- October 1905 to September 1947 (incomplete prior to November 1908).

Average discharge.- 42 years, 7,020 second-feet.

Extremes.- Maximum discharge during year, 74,000 second-feet during night of Dec. 14 

 eight, 22.6 feet, from floodmark); minimum observed, 1,010 second-feet Oct. 1 

(gage height, 1.30 feet).

1905-47: Maximum discharge, 172,000 second-feet Feb. 21, 1927, Dec. 31, 1942, 

from rating curve extended above 50,000 second-feet; maximum gage height, 41.1 feet 

Dec. 31, 1942; minimum discharge observed, 640 second-feet July 18, 1926 (gage height, 

0.71 foot).

Maximum stage known, 45^5 feet sometime in 1861.

Remarks.- Records fair. Gage read twice daily. Some diversions for irrigation from 

streams in South Umpqua River Basin, but low flow probably only "slightly affected. 

Slight fluctuation by gates and racks of fish hatchery at Diamond Lake and by power 

plant at Winchester ordinarily does not affect discharge at this station.

1925-47; Maximum discharge, 2,760 second-feet Nov. 29, 1942 from rating curve extended above 1,100 second-feet; maximum river gage height, 5.2 feet Nov. 29, 1942, Dec. 

28, 1945; minimum discharge, 72 second-feet Aug. 24 to Sept. 5, 1931.

Remarks.- Records fair except those for periods of no gage-height record and those below 

" 10 second-feet, which are poor. Rating curve for river only defined to 240 second-feet 

by measurements and to 1,100 second-feet by study of increments of discharge when flow 

in canal was changed. Low flow in river controlled since Nov. 19, 1931, by, head gates 

at diversion dam of power canal which diverts water around station; practically no 

storage above diversion dam. Records include flow of Middle Fork power canal.

Cooperation.- Water-stage recorder graph furnished by The California Oregon Power Co.

SPRINGS IN THE WALLA WALLA RIVER BASIN, OREG.-WASH. 

Springs in the Walla Walla River Basin, Oreg.-Wash.

265

Ground-water overflow through many springs on the alluvial fan of the Walla Walla River 

near Milton and Preewater, Oreg., amounts to about 50,000 acre-feet a year. During'the 

irrigation season practically all the overflow is used to water crops on land not served 

by diversion from the river. A survey made in 1933 listed 57 springs or spring groups in 

the area, arranged in "inner," "intermediate," and "outer" zones concentric about the apex 

of the alluvial fan. 1

The inner zons is 3 to 3j miles downstream from Preewater and extends from the vicinity 

of Nicholas Spring, which is about half a mile east of the Walla Walla River at McCoy 

Bridge, to springs in the vicinity of Dagger Creek. Within this zone are fully threefourths of the springs in the Walla Walla Basin. The intermediate and outer zones, each 

of which contains only a few springs, are about 2 miles and 4 miles, respectively, beyond 

the inner zone.

In order to bring about a more effective use of the available water supply through a 

better understanding of the relation between surface- and ground-water supplies in the 

basin, discharge measurements of each of the principal springs and measurements of groundwater levels in representative wells have been made and the results published periodically 

since 1932.
