SURFACE WATER SUPPLY OF PACIFIC SLOPE BASINS IN WASHINGTON AND UPPER 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 1888 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 t3rms used 

herein are defined as JCllows:

"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-of* 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 th3 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 24 

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 

gage.

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

1
2 EXPLANATION OF DATA

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. Gaging station structures 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 daily discharge for the greater part of the year was 

determined by the shifting-control method, the slope method, or other special nethods.

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 antf 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 qurlified, 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 rtations. 

Selected lower peaks are also given if\£he peak discharge exceeded the mean die-charge 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 tte mean 

of twice-daily readings. For flashy floods the mean daily 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 mean daily gage height. For stations subject to such fluctuation the 

meandaily gage height may not indicate the true mean daily discharge, which mist be obtained by averaging the discharge for intervals of the day or by using the discharge 

integrator, an instrument for obtaining the mean daily discharge from a continuous gageheight graph and containing as an essential element the rating curve of the ststion.

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 dischgrge. The 

column headed "Maximum" 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

given is the minimum dally discharge. The column headed "Mean" gives the average flow In 

cubic feet per second during the month.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream-flow data depends primarily on (1) the permanence or 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 noncontrlbutlng 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 dally 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 

page 6.

The table on the following page gives, by years and drainage basins, ttn 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 an^ 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 thos-3 years.

The records at most of the stations discussed in these reports extend o''er 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 earlier years published in water-supply papers of the Geological Survey.

Note.- Unpublished records of daily discharge for 1939 and earlier years have been 

collected by the Bureau of Reclamation and Office of Indian Affairs, in connection with 

irrigation and drainage projects, for many canals and drains in Washington.

COOPERATION

The work in the several States was done under cooperative agreements with the organizations listed below:

Idaho: Department of Reclamation, R. W. Faris, commissioner, until Jan. 1, 1939, 

succeeded by James Spofford.

Montana: Office of the State engineer, E. B. Donahue; and State Water Conservation 

Board.

Washington: Department of Conservation and Development, John Brooke Fink, director, 

and C. J. Bartholet, supervisor of hydraulics, Division of Water Resources; cities of 

Aberdeen, Bellingham, Everett, Seattle, and Tacoma; King and Pierce Counties, through 

the Intercounty River Improvement Commission; and Skagit and Whatcom Counties.

Financial assistance was furnished by the Corps of Engineers, U. S. Army, in the operation of two gaging stations in Washington.

Acknowledgment of financial assistance in collecting records published herein is due 

also to the United States Department of State; the Bureau of Reclamation and Office of 

Indian Affairs of the United States Department of the Interior; the Forest Service, Soil 

Conservation Service, and Weather Bureau of the United States Department of Agriculture; 

and the Federal Power Commission.

Funds for the construction, repair, and improvement of gagLng stations were allocated 

to the Geological Survey by the Federal Emergency Administration of Public Works.

Full cooperation exists between this organization and the Dominion Water and Power 

Bureau, Department of Mines and Resources, Canada. On waters adjacent to the international 

boundary certain stations are maintained jointly by the United States and Canada under the 

terms of the Boundary Waters Treaty of 1909, and others are maintained unler a subsequent 

agreement between the two Governments. The records from all these stations are obtained 

in such a manner as to be equally acceptable and available in either country. These 

stations are herein designated "international gaging stations."

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

corporations, and individuals:

Idaho: Washington Water Power Co.

Montana: Montana Power Co. and Glacier Silver Lead Mining Co. 

Washington: Crown Zellerbach Corporation; Hugh L. Cooper Co.; R. G. Hall; Puget 

Sound Power & Light Co.; Washington Water Power Co.; and Western Washington Electric 

Light & Power Co.
10 DIVISION OF WORK

The data for the stations in the several States were collected and prepared for publication under the supervision of district engineers as follows: In Idaho (except for Pend 

Oreille River at Priest River) and for Clark Fork near Heron, Mont., Flathead River at 

Flathead, British Columbia, Kootenai River at Newgate, British Columbia, and Kootenal 

River near Rexford, Mont., T. R. Newell; in Montana (except for the stations noted above),

SKAGIT RIVER BASIN

Skagit River at Newhalem, Wash.

Location.- Water-stage recorder, lat. 48°40', long. 121°15', in SEi sec. 21, T. 37 N., 

R. 12 E., at power plant of city of Seattle at Newhalem, a quarter of a mile upstream 

from Newhalem Creek, 11 miles upstream from Bacon Creek, and 16 miles upstream from 

Marblemount. Zero of gage Is 400 feet above mean sea level (levels of city of 

Seattle).

Drainage area.- 1,160 square miles, of which 390 square miles Is in Canada.

Records available.- December 1908 to May 1914 and October 1920 to September 1939, In

reports of Geological Survey. October 1908 to September 1933 (monthly discharge only), 

In State Water-Supply Bulletin 5.

Average discharge.- 31 years (1908-39), 4,388 second-feet, adjusted for storage since 

October 1929.

Extremes.- Maximum discharge during year, 22,400 second-feet May 29 (gage height, 89.3 

feet); minimum, 262 second-feet (regulated) Nov. 29 (gage height, 79.12 feet); minimum dally, 801 second-feet Mar. 12.

1908-14, 1920-39: Maximum discharge, 60,000 second-feet Dec. 12, 1921 (gage height, 

94.2 feet); minimum, 74 second-feet (regulated) Nov. 10, 1936 (gage height, 78.39 

feet); minimum dally, 136 second-feet Aug. 24, 1930.

Remarks.- Records excellent. Discharge Jan. 4, 5 determined on basis of power-plant

operation at Dlablo. Water Is diverted 3 miles upstream (may be entire low-water flow) 

and Is returned to river at Seattle power plant just upstream from station. Flow also 

partly regulated by Dlablo Reservoir (capacity, 91,300 acre-feet at elevation, 1,205 

feet). Gage-height record collected in cooperation with city of Seattle, which furnished results of several discharge measurements.

SKAGIT RIVER BASIN 59

Skaglt River near Concrete, Wash.

Location.- Water-stage recorder, lat. 48°32', long. 121°46', in sec. 16, T. 35 N., R. 8 

E., at dalles 2 miles downstream from Baker River and 24 miles southwest of Concrete. 

Zero of gage is 130.0 feet above mean sea level (general adjustment of 1929).

Drainage area.- 2,700 square miles, of which 390 square miles is in Canada.

Records available.- September 1924 to September 1939.

Average discharge.- 15 years, 14,420 second-feet, adjusted for storage in lake Shannon 

Reservoir since October 1925 and Diablo Reservoir since October 1929.

Extremes.- Maximum discharge during year, 79,600 second-feet May 29 (gage teight, 30.7 

feet); minimum, 3,580 second-feet (regulated) Oct. 10 (gage height, 13.?8 feet).

1924-39: Maximum discharge, 147,000 second-feet Feb. 27, 1932 (gage height, 40.0 

feet, present datum); minimum, probably less than 2,160 second-feet during Oct. 1-24, 

1925, when recorder was not operating and gates in Baker River Dam were closed for 

first time.

Maximum stage known, 69.3 feet, present datum, from floodmarks (disctarge, about 

500,000 second-feet), occurred about 1815. Records of other floods prior to establishment of station are given in Water-supply Paper 612.

Remarks.- Records excellent. All diversions returned to river upstream from gage. At 

low stages flow partly regulated by operation of power plants on Baker end upper Skagit 

Rivers, and by storage in Diablo and Lake Shannon Reservoirs (see p. 60 ). Records of 

daily discharge not adjusted for change in contents of reservoirs.

Rating table, water year 1938-39 (gage height. In feet, and discharge, in second-feet)

COLUMBIA RIVER MAIN STEM 

Columbia River at Kettle Falls, Wash.

73

Location.- Water-stage recorder, lat. 48°37 1 20", long. 118°07'00", in northwest corner 

lot 1, sec. 14, T. 36 N., R. 37 E., 3t miles upstream from Colville River, at Kettle 

Falls. Zero of gage is at mean sea level (subject to correction for gereral adjustment of 1929).

Drainage area.- 64,500 square miles.

Records available.- April 1913 to September 1939.

Average discharge.- 99,210 second-feet.

Extremes.- Maximum discharge during year, 280,000 second-feet May 31, June 1 (elevation, 

1,190.45 feet); minimum (not determined), probably occurred on Feb. 11 cr 12, when 

stage-discharge relation was affected by ice.

1913-39: Maximum discharge, 468,000 second-feet June 14, 15, 1913 (gage height, 

34.2 feet, from floodmarks, referred to U. S. Weather Bureau gage at Marcus); minimum, 

13,000 second-feet (estimated because of ice effect) Jan. 18-21, 1930, Jan. 31, 1937. 

Maximum discharge during flood of 1894, 700,000 second-feet, based on information 

from several sources.

Remarks.- Records excellent except those for period of ice effect, Feb. 12-14 (computed 

on basis of gage heights and weather records), and those for periods of missing gage 

heights, June 19-24, July 4-6, 16-23 (computed on basis of sum of records for Sheep 

Creek near Northport, Kettle River near Laurier, Pend Oreille River belcw Z Canyon, 

Salmon River near Waneta, B. C., and Columbia River at Birchbank, B. C.), which are 

good. Many diversions upstream from gage for irrigation, but quantity diverted is 

very small in proportion to flow past gage. Slight fluctuation at extreme low water 

caused by operation of power plant on Kootenai River. Natural storage in many lakes 

upstream tends to decrease floods and increase low-water flow.

74 COLUMBIA RIVER Mft.IN STEM

Columbia River at Grand Coulee, Wash.

Location.- Water-stage recorder, lat. 47°58'00", long. 118058'45", opposite lot 4, sec. 

36, T. 29 N., R. 30 E., in pier 3 of highway bridge at Grand Coulee, 2,500 feet downstream from Grand Coulee Dam and 14 miles upstream from Nespelem River. Zero of gage is 

at mean sea level (subject to correction for general adjustment of 1929).

Drainage area.- 74,100 square miles.

Records avallable.- June to December 1923 and June 1928 to September 1939 (complete). 

April 1913 to June 1923 and January 1924 to May 1928 (monthly diecharge cnly).

Average discharge.- 26 years, 107,700 second-feet.

Extremes.- Maximum discharge during year, 290,000 second-feet June 1, 2 (elevation, 967.25 

feet); minimum, 25,500 second-feet Feb. 13 (elevation, 934.65 feet).

1913-39: Maximum discharge, 492,000 second-feet June 15, 1913 (computed on basis of 

records of peak discharge at other raging stations); minimum may have been less than 

15,300 second-feet (estimated) in January or February 1957, when stage-discharge 

relation was affected by ice.

Maximum discharge during flood of June 1894, 725,000 second-feet (estimated).

Remarks.- Records excellent. Discharge for period Sept. 2-5 determined frrm partial gageheight record and general trend of stafe. Diversions for irrigation above station are 

small in proportion to flow past gage. Some diurnal fluctuation caused tv operation of 

power plants on Spokane River and by construction at Grand Coulee Dam. Some regulation 

due to natural storage in many lakes above gage.

R. 34 W., at Leonia, 450 feet east of Montana-Idaho State line and half a mile upstream from Boulder Creek. Zero of gage is 1,700.00 feet above mean see level (U. S. 

Coast and Geodetic Survey datum).

Drainage area.- 11,740 square miles.

Records available.- March 1928 to September 1939.

Average discharge.- 11 years, 12,500 second-feet.

Extremes.- Maximum discharge during year, 47,500 second-feet May 18 (water-surface 

elevation, 1,812.11 feet); minimum, 1,500 second-feet (estimated) Feb. 10; minimum 

water-surface elevation, 1,799.52 feet Feb. 10.

1928-39: Maximum discharge, 95,500 second-feet June 18, 1933 (water-surface 

elevation, 1,818.11 feet); minimum, 996 second-feet Dec. 9, 1936; minimum watersurface elevation, 1,797.56 feet Dec. 10, 1929.

Floods of June 1894 and 1916 reached elevations of 1,824.6 and 1,821.6 feet, 

respectively (Information furnished by Great Northern Railway Co.).

Remarks.- Records excellent except those for periods of ice effect, Nov. 2E-30, Dec. 

11-24, 26-30, Feb. 2, 7-16, 19-23, which were computed on basis of one (fischarge 

measurement, gage heights, weather records, and records for stations at Libby, Mont, 

and Bonners Ferry, Idaho, and those below 3,000 second-feet, all of which are fair. 

No diversion or regulation above station.

Records available.- October 1927 to September 1939 (gage-height record only prior to May 

1929), in reports of Geological Survey. April 1925 to September 1927 (gage heights 

only), In reports of Dominion Water and Power Bureau, Department of Mines and Resources, 

Canada.

Average discharge.- 10 years (1929-39), 14,140 second-feet.

Extremes.- Maximum dally discharge during year, 49,200 second-feet May 18; maximum watersurface elevation, 1,758.30 feet May 19; minimum daily discharge, 1,670 second-feet 

Feb. 10, during Ice period; minimum water-surface elevation, 1.738.94 feet Mar. 18.

1929-39: Maximum daily discharge, 90,500 second-feet June 19, 1933; maximum watersurface elevation, 1,767.98 feet June 20, 1933; minimum dally discharge, 1,350 secondfeet Feb. 8, 1936; minimum water-surface elevation, that of Mar. 18, 1939.

Remarks.- Records of discharge good except those for periods of Ice effect, tCw. 25 to

Dec. 4, Dec. 11 to Mar. 20 (computed on basis of four discharge measurements and records 

for station at Bonners Ferry, intervening Inflow, and channel storage), which are fair. 

Discharge computed from mean elevation-conveyance curve determined on basis of fall In 

reach between station at Klockmann ranch near Bonners Ferry and station at Port Hill 

and discharge measurements made at station near Copeland.

Records of elevation excellent except those for Feb. 8-14, which are fair. Elevations affected by backwater from Kootenay Lake.

Drainage district No. 7, adjacent to Kootenal River above station and below station 

at Bonners Ferry, was not repaired prior to freshet period of 1939 and was partly 

inundated.

Nines and Resources, Canada.

Average discharge.- 11 years, 14,260 second-feet.

Extremes.- Maximum daily discharge during year, 51,100 second-feet May 18; maximum watersurface elevation, 1,755.66 feet May 19; minimum daily discharge, 1,720 second-feet 

Feb. 10; minimum water-surface elevation, 1,738.69 feet Mar. 18.

1928-39: Maximum daily discharge, 93,200 second-feet June 19, 1933; maximum watersurface elevation, 1,764.08 feet May 31, 1938; minimum daily discharge, 1,380 secondfeet Feb. 8, 1936; minimum water-surface elevation, that of Mar. 18, 1929.

Maximum water-surface elevation known, 1,772.7 feet sometime in June 1894.

Remarks . - Records of discharge good except those Nov. 25 to Dec. 4, Dec. 11 to Mar. 20, 

which are fair. Daily discharges, which represent the entire flow passing international 

boundary, were obtained by adding tributary inflow, including that of Boundary Creek, 

to discharge at station near Copeland. Boundary dike of Reclamation Farm repaired 

prior to freshet season, and flow of river confined throughout year to nain channel, 

upon which page and cableway are located.

Records of water-surface elevation excellent. Elevations affected by backvriter 

from Kootenay Lake.

Drainage district Ifo. 10, Severn's Bend district, and Klockmann Boundary farm adjacent to Kootenai River above this station and below station near Copeland v/ere 

repaired prior to freshet period and were not inundated.

SPOKANE RIVER BASIN

Coeur d'Alene Lake at Coeur d'Alene, Idaho

Location.- Water-stage recorder, lat. 47°40', long. 116°46', In sec. 24, T. 50 N., R. 4 

W., 500 feet southwest of south end of Eleventh Street, Coeur d'Alene. Zero of gage 

Is 2,100.00 feet above mean sea level.

Drainage area.- 3,750 square miles.

Records available.- February 1905 to September 1939. April 1903 to February 1905, from 

St. Joe Boom Co.'s gage at mouth of St. Joe River.

Extremes.- Maximum gage height during year, 31.06 feet May 6; minimum, 22.18 feet Sept.

"1903-1939: Maximum gage height, 39.05 feet Dec. 25, 1933; minimum, 19.9 feet Oct. 

10-12, 1904, Sept. 24, 25, 1905, Oct. 14 to Nov. 3, 1906.

Maximum stage known prior to 1903, 37.6 feet, May 31, 1894, from high-water marks.

Remarks.- Records excellent. Washington Water Power Co. stores much water In lake. 

Stage regulated by operation of Talntor gates and bear-trap dam at Post Falls. Gageheight record furnished by Washington Water Power Co.

Bench mark.- The following information has been reprinted from Water-Supply Paper 672, 

page 9b, to make It more readily available.

Original gage Installed Feb. 11, 1905, and all gages since then installed by the 

Geological Survey are referred to Geological Survey bench mark In southeast corner 

of Merrlam Building, at Sherman and Fourth Streets, Coeur d'Alene. The bench mark 

Is firmly set In a substantial building, which has not been moved, and therefore the 

elevation of the bench mark should be the same now as when It was set. Levels referred to the bench mark, however, have sometimes been misinterpreted tecause various 

adjustments In level nets have resulted in changing Its accepted elevation. These 

accepted elevations are as follows:

Original, as published in U. S. Geol. Survey Twenty-first

Ann. Rept., pt. 1, p. 518..................................

Second, as published In U. S. Geol. Survey Bull. 487,

p. 24, and Bull. 567, p. 79................................

Third, as determined by adjustment to fit the U. S. Coast and 

Geodetic Survey precise-level net..........................

Feet 

2,157.404 

2,157.909 

2,154.509

Coeur d'Alene Lake stages, published in Water-Supply Paper 272 and rubsequent 

water-supply papers (Including this one), refer to the original accepted elevation of 

the bench mark (2,157.404 feet). To obtain mean sea-level elevation corresponding to 

the original elevation of the bench mark, add 2,100.00 feet to published stages.
