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

1939

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, 1939. The work was begun in 1880 In connection with special studies 

relating to Irrigation. Measurements of -flow of streams and measurements of stage and contents of lakes and reservoirs have been made at about 8,240 gaging stations In the United 

States and also at many gaging stations In Alaska and Hawaii. In July 1939, 4,160 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. Acknowledgments for cooperation of the first kind are made In connection with the description of each station 

affected; cooperation of the second kind Is acknowledged on page 9.

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 water flowing In a channel when the cross-sectional area Is 1 square foot 

and the 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 run-off Is distributed uniformly both as regards time and area.

"Run-off In Inches" Is the depth to which an area would be covered If all the water 

flowing from It In a given period were uniformly distributed on Its surface. It Is used 

for comparing run-off with rainfall, which Is usually expressed In Inches.

An "acre-foot," equivalent to 43,560 cubic feet, Is the quantity of water required to 

cover an acre to the depth of 1 foot. 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 64 

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

represents a run-off of 0.0372 Inch from one square mile.

"Stage-discharge relation" Is an abbreviation for the term "relation of gage height to 

discharge."

"Control" is a term used to designate the natural section or reach of the channel or 

artificial structure below the gage that determines the stage-discharge relation at the

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 gage heights and discharge

2 EXPLANATION OF DATA

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

direct readings on a nonrecordlng 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 gaging stations, equipped with water-stage recorder and measuring 

cable and car, are shown on plate 1.

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

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

The data presented for each gaging station in the area covered by this report usually 

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

and a table of monthly and yearly discharge and run-off. Skeleton rating tables are published except for those stations whose 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 daily discharge if there is extensive regulation (also the minimum discharge if useful); and the 

minimum gage height (except when 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 represents the 

lowest discharge, unless otherwise qualified. The peak discharge for the year with the 

time of its occurrence is given below the table of monthly discharge for some stations. 

Selected lower peaks are also given If the peak discharge exceeded the mean discharge for 

that day by more than 10 percent. This supplementary Information is generally not given 

for stations having drainage areas of less than 10 square miles or more than 10,000 square 

miles.

The table of daily discharge gives, for stations equipped with nonrecording gages, the 

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

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

subject to sudden or rapid fluctuation, the table gives the discharge corresponding to the 

mean daily gage height. For stations subject to such fluctuation the mean daily gage 

height may not indicate the true mean daily discharge, which must be obtained by averaging 

the discharge for intervals of the day or by using the discharge integrator, an instrument 

for obtaining the mean dally discharge from a continuous gage-height graph and containing 

as an essential element the rating curve of the station.

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

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

column headed "mximum" gives the maximum daily discharge and not the discharge when the 

water surface was at crest height. Likewise, in the column headed "Minimum" the quantity

The accuracy of stream-flow data depends primarily on (1) the permanency of the stagedischarge relation and (2) the. accuracy of observation 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 indicated by monthly means at some stations may vary widely from natural yield, 

owing to diversions, amount consumed, 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 "run-off in inches" are not published unless reservoir 

records are included indicating the extent of the regulation, or 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 run-off 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, so that 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 gives a general idea of the flow at the station. The 

table of daily discharge allows more detailed studies of the variation in flow. It should 

be borne in mind, however, that the observations in each succeeding year may be expected 

to throw new light on data previously published, and that greater degrees of refinement in 

computations and records may be warranted with the increase in data and the use of improved 

equipment.

Note.- The reports that contain records for years after 1901 are given in the table on

-The table on the following page gives, by years and drainage basins, the numbers of 

the papers on surface water supply published from 1899 to 1939. The data for any particular 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.

 Records for some earlier years published In water-supply papers of Geological Survey.

tTJnpubllshed records collected by Office of Indian Affairs.

Note.- Records for stations listed In the above table were collected by the Oregon State engineer and published In bulletins of the State engineer as follows, except as otherwise noted: 

For 1915-24, In Bulletin 7; for 1925-30, In Bulletin 8; and for 1931-36 (some to December) In 

Bulletin 9. Those for years since 1936 have not been published. Records on many canals, also, 

have been collected by the Oregon State engineer and the Bureau of Reclamation In connection 

with the operation of Irrigation projects.

The Soil Conservation Service began In 1938 to make studies of run-off from four areas of 

less than 15 acres each In the vicinity of Newberg, Oreg. The records are In the files of that 

organization.

COOPERATION

The work In the two States was done under cooperative agreements as follows: In 

Oregon, with the State engineer, Charles E. Strlcklln; and In Washington, with the 

Department of Conservation and Development, John Brooke Fink, director, and Charles J. 

Bartholet, supervisor of hydraulics.

Financial assistance was furnished by the Corps of Engineers, United States Army, 

In the operation of 10 gaging stations In Oregon.

244757 O « 2
10 COOPERATION

Funds for the construction, repair, and Improvement of gaging stations were allocated to the Geological Survey by the Federal Emergency Administration of Public Works.

Assistance in collecting records was also rendered by the following municipalities, 

organizations, corporations, and Individuals: In Oregon, by Deschutes, Jackson, 

Josephine, and Umatllla Counties; the cities of Eugene, McMlnnvllle, and Portland; The 

California-Oregon Power Co., Pacific Power & Light Co., and Portland General Electric 

Co. In Washington, by the Inland Power & Light Co. and Northwestern Electric Co.

DIVISION OF WORK

The data for the stations In Oregon were collected and prepared for publication 

under the supervision of G. H. Canfleld, district engineer, the work being done in 

collaboration with Charles E. Strlcklln, State engineer; In Washington, under the 

supervision of G. L. Parker, district engineer.

 COLUMBIA RIVER MAIN STEM

Columbia River near The Dalles, Oreg.

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

15 E., just upstream from Celllo Falls, 3 miles downstream from Deschutes River, and 

11 miles east of The Dalles. Gage readings'above Celllo Falls are elevations above 

mean sea level (general adjustment of 1929). Since January 1937, all discharge measurements made at gaging cableway 9 miles upstream from recorder, with flow of 

Deschutes River added.

Drainage area.- 237,000 square miles.

Records avalla'ble.- June 1878 to September 1939. Prior to October 1931, records based on 

staff 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.- 61 years (1878-39), 197,700 second-feet.

Extremes.- Maximum discharge during year, 387,000 second-feet May 21, 22 (gage height, 

138.9 feet); minimum, 59,700 second-feet Feb. 15 (gage height, 128.13 feet).

1858-39: Maximum discharge, 1,170,000 second-feet June 6, 1894 (gage height, 59.6 

feet on gage at The Dalles and 160.1 feet on gage above Celllo Falls); minimum observed, 35,000 second-feet Jan. 12, 1937 (gage height, 126.0 feet on gage above Celllo 

Falls).

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

of total run-off. Recorder Inspected by employees of Corps of Engineers, U. S. Army.

R. 11 E., three-quarters of a mile downstream from Lava Island, 1 mile downstream 

from intake of Arnold canal, and 6 miles southwest of Bend.

Records available.- March 1926 to September 1939. 

Average discharge.- 13 years, 1,071 second-feet.

Extremes.- Maximum discharge during year, 1,440 second-feet July 5-7, 25, 27, 28 (gage 

 hei^it, 1.31 feet); minimum, 844 second-feet Dec. 14 (gage height, 0.57 foot), caused

by Ice jam upstream.

1926-39: Maximum discharge, -1,780 second-feet Jan. 3, 1928 (gage height, 1.55

feet); minimum, 612 second-feet Feb. 9, 1933 (gage height, 0.16 foot).

Remarks.- Records excellent except those for periods of shifting control, Oct. 1-10,

98 WILLAMETTE RIVER BASIN

Coyote Creek near Elmlra, Oreg.

Location.- Staff gage, lat. 44°04'15", long. 123°17'25", at southwest corner of sec. 22, 

T. 17 S., R. 5 W., at road crossing 3 miles east of Elmira. Zero of gage Is 353.7 

feet above mean sea level (general adjustment of 1929).

Drainage area.- 123 sojiare miles.

Records available.- October 1935 to December 1936, January to September 1939.

Extremes .- Maximum discharge observed during year, 1,610 second-feet Feb. 7 (gage height, 

7.36 feet); practically no flow Aug. 15 to Sept. 8, Sept. 19-30.

1935-36, 1939: Maximum discharge observed, 5,000 second-feet Jan. 13, 1936 (gage 

height, 10.0 feet); minimum discharge, that of Aug. 15 to Sept. 8, Sept. 19-30, 1939.

Remarks .- Records fair. Drainage area at station and measurements of flood discharge are 

uncertain because of overflow in wide valley at gage merging into other streams; floodmeasurements include all flow crossing road for Ik miles west and 2 miles east of 

station, which is considered to be the total discharge from the tributary area. No 

diversion or artificial regulation.

Location.- Staff gage, lat. 45°21'10", long. 122°40'35", in SWi sec. 34, T. 2 S., R. 1 E.,

300 feet upstream from county bridge and 1 mile northwest of Willamette. Zero of gage

Is 86.63 feet (revised) above mean sea level (general adjustment of 1929), by surveys

of Corps of Engineers, U. S. Army. 

Drainage area.- 710 square miles. 

Records available.- July 1928 to September 1939.

Average discharge.- 11 years, 1,361 second-feet (including flow of Oswego canal). 

Extremes (river only).- Maximum discharge observed during year, 7,170 second-feet Feb.

18, 19 (gage height, 9.34 feet); minimum observed, 4 second-feet Sept. 28-30.

1928-39: Ifexlmum discharge, 23,300 second-feet Dec. 23, 1933 (gage height, 16.7

feet, observed at peak); minimum observed, 2 second-feet Aug. 14-21, 1928 Tgage height,

0.25 foot). 

Remarks.- Records of discharge of river are good except those below 20 second-feet, which

are fair. Records of discharge of Oswego canal are poor to June 28, good thereafter.

mean sea level, general adjustment of 1929). Auxiliary gage at outlet of Oswego Lake 

for determination of backwater effect of lake on stages at canal gage.

Records available.- October 1928 to September 1939. 

Average discharge.- 11 years, 60.3 second-feet.

Extremes.- Maximum discharge observed during year, 124 second-feet Jan. 11 (gage height, 

5.62 feet); practically no flow part of June 13-16, 21, 22.

1928-39: Maximum discharge, about 6,000 second-feet Dec. 23, 1933 (gage height, 

16.1 feet), computed from slope, area, and lake-spillway data; practically no flow at 

times.

Remarks.- Records poor prior to June 28, good thereafter. Discharge computed on basis of 

gage heights, discharge measurements, and backwater effect as indicated by Oswego Lake 

gage. Oswego canal diverts water from Tualatin River in NWi sec. 20, but diversion 

dam is in NEi sec. 33, about 3 miles downstream.

UMPQUA RIVER BASIN 143

Umpqua 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. Zero of gage Is approximately 95 feet above mean sea level (river 

profile map).

Drainage area.- 3,680 square miles.

Records available.- October 1905 to September 1939 (prior to November 1908, Incomplete).

Average discharge.- 34 years, 7,100 second-feet.

Extremes.- Maximum discharge observed during year, 57,300 second-feet Mar. 13 (gage

height, 19.0 feet); minimum observed, 834 second-feet Sept. 26, 27, 29, 30 (gage height, 

1.08 feet).

1905-39: 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, 1936 (gage height, 0.71 foot). 

Maximum stage known, 45.5 feet sometime In 1861.

Remarks.- Records good. Some diversions for irrigation from streams In South Umpqua River 

Basin, but low-water flow probably only slightly affected. Slight regulation by gates 

and racks of fish hatchery at Diamond Lake and by power plant at Winchester ordinarily 

does not affect discharge at this station. Qage read twice daily.

Location.- Water-stage recorder, lat. 43°16', long. 122°25', in T. 26 S., R. 3 E. (unsurveyed), an eighth of a mile downstream from mouth of Clear-water River, half a mile upstream from Toketee Falls, and 30 miles east of Hoaglin. Zero of gage is 2,373 feet 

above mean sea level, by surveys of The California Oregon Power Co.

Drainage area.- 337 square miles.

Records available.- February 1908 to July 1909, December 1914 to November 1917 (incomplete), July 1924 to September 1939.

Average discharge.- 14 years (1925-39), 859 second-feet.

Extremes.- Maximum discharge during year, 1,680 second-feet Mar. 24, 25 (gage height, 

2.48 feet); minimum, 600 second-feet Sept. 27-30 (gage height, 0.88 foot).

1908-9, 1914-17, 1924-39: Maximum discharge, 3,600 second-feet Feb. 20, 1927 

(gage height, 4.65 feet), from rating curve extended above 1,600 second-feet on basis 

of velocity-area studies; minimum, 475 second-feet Nov. 27-29, Dec. 12, 14, 1931.

Remarks.- Records good except those for period of missing gage heights, Nov. 23 to Feb. 

25, which were computed on basis of recorded range of stage, weather reports, and 

records for North Umpqua River below Lake Creek and above Rock Creek and are poor. No 

diversion above station; regulation at Diamond Lake has little effect.

Discharge, in second-feet, water year October 1938 to September 1939

ROGUE RIVER BASIN 155

Rogue River below South Fork of Rogue River near Prospect, Oreg.

Location.- Water-stage recorder, lat. 42°42', long. 122°36', in NW-J sec. 16, T. 33 S., R. 

2 E., at bridge 6 miles southwest of Prospect. Zero of gage is about 1,708 feet above 

mean sea level (river profile map).

Drainage area.- 643 square miles.

Records available.- April 1929 to September 1939.

Average discharge.- 10 years, 1,533 second-feet.

Extremes.- Maximum discharge during year, 7,400 second-feet Dec. 3 (gage height, 5.85 

feet); minimum, 638 second-feet Sept. 16 (gage height, 0.23 foot); minimum daily, 842 

second-feet Sept. 28.

1929-39: Maximum discharge, about 12,600 second-feet Mar. 19, 1932 (gage height, 

8.7 feet), from rating curve extended above 5,700 second-feet; minimum gage height and 

minimum daily discharge not determined, as stage falls too low at times to be recorded.

Remarks.- Records good except those for periods of faulty or missing gage heights, which 

are fair. Minor diversions for irrigation above station. Considerable diurnal fluctuation caused by operation of power plant 4 miles upstream. Water-stage-recorder graph 

furnished by The California Oregon Power Co.

SPRINGS IN THE WALLA WALLA RIVER BASIN, OREGON-WASHINGTON 181

SPRINGS IN THE WALLA WALLA RIVER BASIN, OREGON-WASHINGTON

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

River near Milton and Freewayer, 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 

that is not served by diversions from the river. The water users have a vital interest 

in the amount and variation of ground-water overflow, because (1) the acreage of crop 

land under irrigation in the basin is greater that can be watered from the Walla Walla 

River in years of small run-off, (2) the variation in spring discharge depends on the 

range in stream flow and the time and place of irrigation on the upper part of the fan, 

and (3) the springs are fed from a body of ground water from which irrigation wells also 

draw a considerable supply.

A survey made in May and June 1933, listed 57 springs or spring groups in the area.i' 

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, ground-water levels and ground-water discharge are being measured periodically 

at representative wells and at the 18 principal springs or spring groups.

A noteworthy feature of the springs is their occurrence in three parallel zones that 

are concentric about the apex of the alluvial fan. The inner zone is 3 to 3i 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 McCoy Bridge, to springs in the 

vicinity of Bugger Creek. Within this zone are fully three-fourths of the springs in 

the Walla Walla Basin. The intermediate and outer spring zones, each of which contains 

only a few springs, are about 2 miles and 4 miles, respectively, beyond the inner zone.

Variations in the discharge of the springs follow largely fluctuations in elevation 

of the ground-water table. These fluctuations depend chiefly on the height of groundwater waves that are created by successive freshets in the Walla Walla River and that 

pass outward through the alluvial fan as the freshets wane, or they may be caused by 

deep infiltration of water applied to the land for irrigation and, in lesser degree, 

to deep infiltration of rainfall and to pumpage from irrigation wells.

YEARLY-DISCHARGE SUMMARY 

PART 14. PACIFIC SLOPE BASINS IN OREGON AND LOWER COLUMBIA RIVER BASIN

The following tables summarize In convenient form for general reference and for use in 

preliminary investigations the figures of yearly discharge and run-off for certain gaging 

stations in the Pacific Slope basins in Oregon and Lower Columbia River Basin, previously 

published in the annual series of water-supply papers. All gaging stations, both active 

and discontinued, at which 10 or more complete years of record have been collected and 

published are represented, also some special stations, as noted below. The summaries present figures of maximum and minimum daily discharge and yearly mean discharge and run-off, 

for both the water years ending September 30 and the calendar years. The figures for the 

water years prior to 1911 and figures for the calendar years 1911 to 1933 have not been 

previously published in the annual water-supply papers but are included in these summaries.

The number of the water-supply paper in which the figures of daily and monthly discharge 

as well as yearly discharge are published is shown in the column headed W.S.P. (no. and 

page). The descriptions contained in the water-supply papers indicated give detailed information relative to the gaging stations, including location, diversions, regulation by 

storage, effect of irrigation, and other pertinent information. Records for stations which 

were operated prior to 1901 are generally contained in the annual reports of the Geological 

Survey. Reference is made to these reports if records have not also been published in 

water-supply papers.

Figures of drainage area are given for each station when known. These figures have been 

revised from time to time as more accurate maps have become available. The discharge per 

square mile and run-off in inches in the following tables, in general, have been revised 

according to the latest figure for the drainage area.

Summaries for incomplete years are given for those stations in irrigated regions for 

which seasonal records were collected in order to show the flow available for irrigation. 

An incomplete year is included for other stations if the maximum daily discharge or minimum 

daily discharge for all the years of record occurred in that year.

Former names under which records for some of the stations have been published in the 

annual water-supply papers are indicated in these yearly summaries as follows:

1. If the name of the stream or town or other feature to which the station is referred 

has been changed, the former name is given in parentheses, indicating that records for 

some of the earlier years are published under the obsolete name.

2. If the entire name of a station has been changed, the superseded name and years when 

it was used are given in parentheses beneath the present name.
