SURFACE WATER SUPPLY OF PACIFIC SLOPE BASINS IN OREGON AND LOWER COLUMBIA RIVER BASIN,

1941

SCOPE OF WORK

This volume Is one of a series of 14 reports 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, 1941. The work was begun In 1888 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 9,120 gaging stations 

In the United States and also at many gaging stations In Alaska and Hawaii. In July 1941, 

4,850 gaging stations were being maintained by the Geological Survey and cooperating organizations. Miscellaneous discharge measurements were made 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 on page 11.

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 le 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.

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

1
2 EXPLANATION OF DATA

measurements In determining the dally 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 on plate 1.

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

dally 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 dally mean discharge Is 

determined by the "shifting-control method," In which correction factors based on Individual discharge measurements are used in applying the gage heights to the rating tables.

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 from 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. The days 

included in the periods of Ice effect and the days during the winter period on which discharge measurements were made are Indicated in the table by symbols referring to footnotes.

For most of the gaging stations on streams In the area covsred 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 dally 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 

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 minimum dally discharge If there is extensive regulation (also the minimum discharge If useful); and the 

minimum 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. Tills supplementary information is generally omitted for stations having drainage areas of less than 10 square miles or more than 10,000 square miles or if the peak 

discharges usually exceed the corresponding mean discharges for the day by less than 10 

percent.

For stations equipped with nonrecording gages, the table of dally discharge gives 

the discharge in second-feet corresponding to once-daily readings of the gage or the mean 

of twice-daily readings. For flashy floods the daily mean discharge is determined from 

gage-height graphs based on gage readings made once or twice daily or oftener, as stated 

in the station description. 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 dally mean gage height. For stations subject to such fluctuation the 

dally mean gage height may not Indicate the true dally 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.

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 and 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 lakee and reservoirs the data presented comprise a description of the station and a monthly summary table of stage and contents. For a few of the 

more important lakes and 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.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream-flow data depends primarily on (1) the permanency of the stagedischarge relation 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 daily records are accurate within 

5 percent; "good," within 10 percent; "fair," within 15 percent; and "poor," within 20 or 

a higher percent.

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 "secondfeet 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
4 ACCURACY OF FIELD DATA AND COMPUTED RESULTS

satisfactory adjustments can be made for changes In contents of reservoirs or for other 

changes Incident to use and control. Figures of second-feet per square mile and runoff 

In Inches are also omitted If the drainage area Includes large noncontrlbuting 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.

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, 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. 6), contains a summary of yearly discharge at gaging 

stations In the area covered by that report. Gaging stations at which 10 or more complete years of record have been collected are represented. These summaries are available 

also as separate reprints.

From tine to time reports have been published that are compilations of records for 

various areas, usually a single Stglte or drainage basin. These reports contain records 

previously published (some of which have been revised), as well as some records not contained In the annual series of water-supply papers. The following table gives the numbers and titles of these reports, krranged In alphabetical order by States and drainage

basins.

* Records for some earlier years published in water-supply papers of the Geological Survey.

Hote.- Records prior to 1936 Indicated above as collected by the Oregon State engineer (some in 

cooperation with Bureau of Reclamation) are contained in bulletins of the State engineer as 

follows: For 1915-24, in Bulletin 7; for 1925-30, in Bulletin 8; and for 1931-36 (some to December 1936) in Bulletin 9. Records subsequent to 1936 collected by the officer mentioned and all 

other records here listed have not been published.

The Soil Conservation Service began in 1938 to collect records of run-off from four areas of 

less than 22 acres each in the vicinity of Newberg, Oreg. These records are available in the files 

of that organization.
COOPERATION 11

The work In the two States was done under cooperative agreements with the organizations listed below:

Oregon: State engineer, Chjarles E. Stricklln; Uinatilla County Court; 

and cities of McMlnnvllle and Portland.

Washington: Department of ponservation and Development, John Brooke 

Fink, director, succeeded by fid Davls, and Charles J. Bartholet, supervisor of hydraulics; and Columbia and Walla Walla Counties.

Financial assistance was furnished by the Corps of Engineers, U. S. Army, for the 

operation of 32 gaging stations In Oregon and 4 In Washington.

Financial assistance was also fujrnlshed by the Bureau of Reclamation. 

Assistance In collecting records! was also rendered by the following counties, municipalities, and corporations:

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

Klamath, and Umatllla; city of Eugene; The California Oregon Power Co., 

Inland Power & Light Co., Pacific Power & Light Co., Portland General Electric Co., and West Coast Power Co.

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

DIVISION OF WORK

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

Survey Glenn L. Parker, chief hydraulic engineer, Carl G. Paulsen, assistant chief 

hydraulic engineer, and Rudolph G. Kasel, chief of the division of surface waters. The 

data for the stations in the two States were collected and prepared for publication under 

supervision of district engineers as follows: In Oregon, G. H. Canfleld, the work being 

done in collaboration with Charles E. Strlcklin, State engineer; in Washington, F. M. 

Veatch.

The records were reviewed and the manuscript prepared for publication under the 

direction of B. J. Peterson, engineer in charge, and M. C. Boyer, associate engineer,

a No gage-height record; discharge computed on basis of records for Salmon Creek near Oakridge.
94 WILLAMETTE RIVER BASIN

Waldo Lake outlet near Oakridge, Oreg.

Location.- Water-stage recorder and artificial control on lake outlet, lat. "43046', long. 

 liii}°03', In NWi sec. 7, T. 21 S., R. 6 E., on artificial outlet channel of Waldo Lake,

20 miles east of Oakridge. Altitude of water surface of lake and of gage, 5,410 feet

(from topographic map).

Drainage area.- 30 square miles.

Records available.- October 1936 to September 1941.

Extremes.- Maximum discharge during year, 16 second-feet June 19-22 (gage height, 0.61 

root, disregarding peaks of momentary duration caused by seiches); practically no flow, 

Oct. i to Jan. 13, Sept. 19-30 (lake level below weir crest).

1936-41: Maximum discharge, 92 second-feet Mar. 29, 193S (gage height, 2.15 feet); 

no flow at times.

Remarks.- Records good except those below 1 second-foot and those for periods of no gageneight record, which are poor. At times seiches on Waldo Lake cause rapid changes In 

stage at gage several times per hour. Lake not regulated artificially. Diversion 

tunnel Into head of Black Creek, near south end of lake, built about 1914, Is not used, 

but an unmeasured leakage passes control gates, which were probably closed throughout

e Computed on basis of one figure of daily discharge, weather records, and records for station on 

Odell Creek near Crescent.
WILLAMETTE RIVKR BASIN 95

North Fork of Middle Fork of Wlllamette River near Oakridge, Oreg.

Location.- Water-stage recorder, lat. 43°45', long. 122°30', In SWi sec. 7, T. 21 S., R.

3 E., 1 mile upstream from mouth and 2i miles northeast of Oakridge. Datum of gage

Is 1,029.6 feet above mean sea level (river-profile survey). 

Drainage area.- 246 square miles. 

KBCprcis available.- October 1909 to September 1912 (fragmentary), September 1935 to

September 1941. October 1913 to February 1916, at site half a mile upstream, above a

small tributary. 

Extremes.- Maximum discharge during year, 3,450 second-feet Nov. 29 (gage height, 5.87

reet, from floodmark); minimum, 40 second-feet May 3 (gage height, 0.37 fbot); minimum

daily, 102 second-feet Oct. 18, 19.

1909-16, 1935-41: Maximum gage height observed, 12.4 feet Nov. 22, 1909, site and

datum then in use .(discharge not determined); minimum discharge, 26 second-feet

(regulated) Oct. 14, 1939. 

Remarks.- Records excellent except those for periods of partly estimated gage-height recora and those based on staff-gage readings, which are good. Tunnel and Sontrol'gates

that were built to divert part of outflow from Waldo Lake into Salmon Creek Basin were

not used during year. Leakage under gates amounts to about 3 second-feet. Occasional

diurnal fluctuation during periods of low-flow caused by logpond above station. 

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

 at highway bridge at Farmington, 7t mllea eouthweet of Beaverton. Auxiliary staff gage 

at highway bridge 6i miles downstream, 1 mile northeast of Scholls. Datum of eaoh gage 

is 100.58 feet above mean sea level, datum of 1929; prior to Oct. 1, 1940, datum of eaoh 

gage was 2.00 feet higher. All discharge measurements made at Farmington. 

Drainage area.- 568 square miles.

eord available " .- October 1939 to September 1941. 

Extremes-'- Maximum discharge observed during year, 6,960 second-feet Jan. 21 (gage height,

feet); minimum observed, 34 second-feet Aug. 22.

height observed, 29.2 feet Feb. 9, 1940; minimum discharge observed, that of Aug. 

1941Maximum stage known, about 37 feet (present datum) at Farmington, Dec. 22 or 23, 

1933 Remarks!- Records for October poor; others good above and fair below 900 second-feet.

 Dally discharge ascertained from stage at Farmington, at times using fall in water surface between gages at Farmington and near Scholls as a factor. Stage-discharge .relation 

affeoted at times by flashboards on low dam 30 miles downstream. Slight regulation by 

log ponds and dam below Oaston have little effect at this station; considerable pondage 

between this station and the one near Willamette. Some diversions above station by 

pumping for irrigation, chiefly at Wapato Lake, near Qaston. Gages read twice dally.

UKPQUA RIVER BASIN 181

Utnpqua River near Elkton, Oreg.

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

miles south 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 1941 (incomplete prior to November 1908).

Average discharge.- 36 years, 6,987 second-feet.

Extreme^.- Maximum discharge during year, 70,400 second-feet Dec. 27 (gage height, 21.8 

feet, from graph based on gage readings), from rating curve extended above 50,000 

second-feet; minimum observed, 868 second-feet Oct. 17-20 (gage height, 1.12 feet).

1905-41: Maximum discharge, 172,000 second-feet Feb. 21, 1927 (gage height, 41.0 

feet, from floodmark), from rating curve extended above 50,000 second-feet; minimum 

observed, 640 second-feet July 18, 1926 (gage height, 0.71 foot). 

Maximum stage known, 45.5 fset sometime in 1861.

Remarks.- Records good. Some diversions for Irrigation from streams in South Umpqua 

 River Basin, but low flow probably only slightly affected. Slight diurnal fluctuation caused by gates and racks of fish hatchery at Diamond Lake and by power plant 

at Winchester ordinarily does not affect discharge at this station. Oage read 

twice dally.

Springs In the Walla Walla River Basin, Oreg.-wash.

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

River near Milton and Freewater, 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.l

The Inner zone Is 3 to 34 miles downstream from Freewater and extends from the vicinity of Nicholas Spring, which Is about half a mile east of the Walla Walla River at McCoj 

Bridge, to springs In the vicinity of Dugger 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 periodically since 1932. Results of 

previous discharge measurements have been published In Water-supply Papers 834, 864, 884, 

and 904.
