SURFACE WATER SUPPLY OF PACIFIC SLOPE BASINS IN WASHINGTON AND UPPER COLUl^IA RIVER

BASIN, 1938

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, 1938. The work was begun In 1888 In connection with special studies 

relating to irrigation. Measurements of stream flow have been made at about 7,800 points 

in the United States and also at many points in Alaska and the Hawaiian Islands. In July 

1938, 3,830 gaging stations were being maintained by the Geological Survey and cooperating 

organisations. Many miscellaneous discharge measurements were made at 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. Aknowledgments 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 or water represented by a flow of 1 second-foot for S4 

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 inches from one square mile.

"Stage-discharge relation" is an abbreviation for the term "relation of grge height to 

discharge."

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

artificial structure below the gage which 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 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 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 daily gage height to these rating tables gives the 

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 par": 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. Information under "Extremes" gives 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, and 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 quali-fied. 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 or the mean of twice-daily readings 

of the gage. 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 the table gives the 

discharge corresponding to the mean daily gage height except for stations on streams subject to sudden or rapid fluctuation. 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 daily discharge from a continuous gag3-height graph 

and containing as an essential element the rating curve of the station.

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

for each month of the figures for that month given in the table of daily discharge. 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 daily discharge. The column headed "Mean" is 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 (1) on the permanency of the stagedischarge relation and (2) on 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 

percent or more.

The monthly means for any station may represent with high accuracy the quantity of 

water flowing past the gage, but the figures showing discharge per square mile and depth 

in inches may be subject to gross errors caused by the inclusion of large no^contributing 

districts in the measured drainage area, by lack of information concerning wjter diverted 

for Irrigation or other use, or by inability to interpret the effect of artificial regulation of the flow of the river above the station. "Second-feet per square mile" and 

"run-off in inches" are therefore not computed if such errors appear probable. The computations are also omitted for stations on streams draining areas in which the annual 

rainfall 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 Increased data and use of improved 

equipment.

Note.- The reports that contain records after 1901 are given in the table on page 6.

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 1938. 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 from 1910 to 1920 for any station in 

the area covered by part 3 are published in Water-Supply Papers 283, 303, 333, 353, 405, 

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 ovsr 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 OF DISCHARGE COLLECTED BY AGENCIES OTHER THAN THE GEOLOGICAL SURVEY

Records of dally discharge of Reservation Drain at Alfalfa, Wash., for 1P23-38 were 

collected by the Office of Indian Affairs and have not been published. Records for some 

earlier years were published in water-supply papers of the Geological Survey.

Unpublished records of daily discharge for 1938 and earlier years have been collected 

by the Bureau of Reclamation for many canals in Washington in connection with irrigation 

projects.
DIVISION OF WORK 9

COOPERATION

The work was done under cooperative agreements with the several States as follows: 

In Idaho, with the Department of Reclamation, R. W. Faris, commissioner. In Montana, 

with the office of the State engineer, J. S. James, succeeded by E. B. Donahue; and with 

the State Water Conservation Board. In Washington, with the Department of Conservation 

and Development, John Brooke Fink, director, and C. J. Bartholet, supervisor of hydraulics. 

Division of Water Resources; with the cities of Aberdeen, Everett, Seattle, and Tacoma; 

with King and Pierce Counties, through the Intercounty River Improvement Comnission; with 

Skagit and Wnatcom Counties; and with Wenatchee Reclamation District.

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, and the Forest Service 

and Weather Bureau of the United States Department of Agriculture.

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 under 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: In Idaho, by the city of Sandpoint and the 

Washington Water Power Co.; in Montana, by the Rocky Mountain Power Co. and the Glacier 

Silver Lead Co.; in Washington, by the Crown Zellerbach Corporation, Hugh L. Cooper Co., 

R. G. Hall, West Coast Power Co., the Puget Sound Power & Light Co., the Washington Water 

Power Co., and the Western Washington Electric Light & Power Co.

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

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

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 Kootenai 

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

above), W. A. Lamb until February 9, 1938, succeeded by A. H. Tuttle; in Washington and 

for Pend Oreille River at Priest River, Idaho, G. L. Parker.

36 LAKE WASHINGTON BASIN

Cedar River near Landsberg, Wash.

Location.- Water-stage recorder, lat. 47°23'35", long. 121°56'5Q", in sec. 17, T. 22 N., 

R. 7 E., IS miles upstream from Landsberg and intake of Seattle water-supply system, 

7 miles upstream from Maple Valley, and 12 miles downstream from Cedar Lake.

Drainage area.- 138 square miles.

Records available.- April 1914 to September 1938, July 1895 to September 1898 (at site 

2 miles downstream), and March 1901 to April 1912 (at site of Seattle water-supply 

intake) in reports of Geological Survey. August 1895 to April 1912 ard May 1914 to 

September 1933 (monthly discharge) in State Water-Supply Bulletin 5; records equivalent.

Average discharge.- 40 years (1895-1911, 1914-38), 703 second-feet.

Extremes.- Maximum discharge during year, 2,360 second-feet (regulated) Fov. 29 (gage 

height, 3.91 feet); minimum, 257 second-feet (regulated) Sept. 15 (gage height, 1.04 

feet).

1895-98, 1901-12, 1914-38: Maximum discharge observed, 13,600 seccnd-feet Nov. 

19, 1911 (gage height, 9.7 feet, former site and datum); minimum, 83 eecond-feet Sept. 

19, 1898.

Remarks.- Records excellent. Flow of Rock Creek, entering naturally just above station, 

has been diverted to a point below Seattle municipal water supply intsice to lessen ' 

danger of pollution. No diversion Nov. 14 to Apr. 14. Figures of morthly discharge, 

adjusted for diversion, were computed on basis of three discharge measurements, 69 

observations of stage, and difference in flow of river between statiors near Landsberg and at Cedar Falls. All other diverted water returned to river above station. 

Flow partly regulated by storage and release of water at Cedar Lake Reservoir. Gageheight record collected in cooperation with city of Seattle.

Skagit River near Concrete, Wash.

Location.- Water-stage recorder, lat. 48°32', long. 121°45' In sec. 16, T. 35 N., R. 8 

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

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

lowered 12.69 feet Oct. 1, 1937.

Drainage area.- 2,700 square miles, of which 390 square miles Is In Canada.

Records available.- September 1924 to September 1938.

Average discharge.- 14 years, 14,440 second-feet.

Extremes.- Maximum discharge during year, 89,600 second-feet Oct. 28 (gage height, 32.16 

feet); minimum discharge recorded, 2,840 second-feet Oct. 11 (gage height, 12.94 feet).

1924-38: Maximum discharge, 147,000 second-feet Feb. 27, 1932 (gage height, 40.0 

feet, present datum); minimum, probably less than 2,160 second-feet sometime during 

period Oct. 1-24, 1925, when recorder was not operating and when gates In Baker River 

dam were closed for first time.

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

500,000 second-feet), occurred sometime In about the year 1815. Records of other 

floods prior to establishment of station are given In Water-Supply Paper 612.

Remarks.- Records excellent except those for period of partial gage-height record, Oct. 

9-287 which was computed on basis of 29 gage readings and fragmentary recorder graph, 

and are good. Discharge for Sept. 16, 17 interpolated. All diverted water returned 

to river above gage. At low stages flow partly regulated by storage at power plants 

on Baker and upper Skagit Rivers. Capacity of Lake Shannon Reservoir, o-> Baker River, 

156,200 acre-feet at elevation 435 feet. Capacity of Diablo Reservoir, on upper 

Skagit River, 91,300 acre-feet at elevation 1,205 feet.

62 NOOKSACK RIVER BASIN

Nooksack River near Glacier, Wash.

Location.- Water-stage recorder, lat. 48°54'30", long. 121°59'30", in NEi sec. 2, T. 39 

N., R. 6 E., 600 feet downstream from Canyon Creek and 2i miles northwest of Glacier.

Drainage area.- 195 square miles.

Records available.- February 1934 to September 1938 (discontinued);?) Septenter 1910 to 

September 1911 (fragmentary), at practically same site.

Extremes.- 1936-37: Maximum discharge during year, 6,150 second-feet June 21 (gage height, 

6.0 feet); minimum, 186 second-feet (revised) Feb. 14, 15.

1937-38: Maximum discharge during year 9,400 second-feet Oct. 28 (gs.ge height, 

7.74 feet), from rating curve extended above 6,000 second-feet; minimum, 248 secondfeet Feb. 20.

1910-11, 1954-38: Maximum discharge, that of Oct. 28, 1937; minimum, 130 secondfeet Oct. 17, 1934.

Remarks.- Records fair except those for period of ice effect, Jan. 7 to Fet. 4, 1937, 

which were computed on basis of gage heights, weather records, and records for South 

Fork near Wickersham and are poor. Water diverted for Excelsior power plant of Puget 

Sound Power & Light Co. returned to river above gage. Regulation due tc operation of 

plant produces only slight effect at gage. Records for water year 1936-37 supersede 

those published in Water-supply Paper 832.

66 UPPER COLUMBIA RIVER BASIN

COLUMBIA RIVER MAIN STEM

Columbia River at Blrchbank, British Columbia 

(Formerly published as Columbia River at Trail, British Columbia)

(International gaging station)

Location.- Water-stage recorder, lat. 49°10', long. 117°43', at Birchbank, 7 miles up-

 stream from Trail, 11 miles downstream from Kootenai River, and 17 milee upstream 

from international boundary. Zero of gage is 1,338.01 feet above sea level (from 

levels by Geodetic Survey of Canada in 1930). Prior to October 1937 cable gage at 

site at Trail, 7 miles downstream.

Drainage area.- 34,000 square miles. Records available.- April 1913 to September 1937 (at site at Trail) and October 1937 to 

September 1938.

Average discharge.- 25 years, 70,960 second-feet.

Extremes.- Maximum discharge during year, 260,000 second-feet June 27 (gage height, 40.00

 feet); minimum, 15,100 second-feet Mar. 9 (gage height, 5.18 feet).

1913-38: Maximum discharge observed, 312,000 second-feet June 14, IF. 1913 (gage

height, 41.6 feet, Trail gage); minimum observed, 8,940 second-feet Feb. 3, 1937

(gage height, 6.27 feet, Trail gage). 

Remarks.- Records excellent. Discharge for period of missing gage heights, Oct. 2-26,

 Mar. 2, computed on basis of records at site at Trail. Small amount of water diverted 

above station for irrigation. Some fluctuation at low water caused by operation of 

power plant on Kootenai River. Natural storage in numerous lakes affects flow. This 

is one of the international gaging stations maintained by Canada under agreement 

with the United States.

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

of Kettle Falls. Zero of gage is at mean sea level (subject to correction for general 

adjustment of 1929).

Drainage area.- 64,500 square miles.

Records available.- April 1913 to September 1938.

Average discharge.- 25 years, 99,650 second-feet.

Extremes.- Maximum discharge during year, 345,000 second-feet June 8 (elevation, 1,193.7 

feet); minimum, £6,700 second-feet Feb. 16 (elevation, 1,167.84 feet).

1913-38: Maximum discharge, 468,000 second-feet June 14, 15, 1913 (gage height, 

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

13,000 second-feet (estimated because of ice effect) Jan. 18-£1, 1930, Jan. 31, 1937. 

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

from several sources.

Remarks.- Records excellent. Many diversions above station for Irrigation, but quantity 

diverted is very small in proportion to flow past station. Slight fluctuation at extreme low water caused by operation of power plant on Kootenai River. Some regulation 

due to natural storage in numerous lakes above station.

*Diseharge Interpolated.

tGage-height record faulty; discharge computed on basis of records for related stations.
68 COLUMBIA RIVER MAIN STEM

Columbia River at Grand Coulee-, Wash.

Location.- Water-stage recorder, lat. 47°o8'OQ", long. 118°58'45", 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, 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 available.- June to December 1923, June 1928 to September 1938 (complete). April 

1913 to June 1923 and January 1924 to May 1928 (monthly discharge only).

Average discharge.- 25 years, 108,200 second-feet.

Extremes.- Maximum discharge during year, 364,000 second-feet June 8 (elevation, 972.80 

feet); minimum, 34,000 second-feet Feb. 26 (elevation, 936.64 feet).

1913-38: Maximum discharge, 492,000 second-feet June 15, 1913 (computed on basis 

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

than 15,300 second-feet (estimated) in January or February 1937, when stage-discharge 

relation was affected by ice.

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

Remarks.- Records excellent. Diversions for irrigation above station are small in proportion to flow past gage. Some diurnal fluctuation caused by operation of power 

plants on Spokane River. Some regulation due to natural storage in many lakes above 

gage.

Creek ana 1$ miles northwest of Copeland. Zero of gage is 1.700.00 fe-st above mean 

sea level (U. S. Coast and Geodetic Survey datum).

Drainage area.- 13,400 square miles.

Records available.- October 1927 to September 1938 (only gage heights prior to May 1929) 

in reports of Geological Survey. April 1925 to September 1927 (gage hsights only) in 

reports of Dominion Water and Power Bureau, Department of Mines and Resources, Canada.

Extremes.- Maximum dally discharge during year, 87,400 second-feet May 29; maximum watersurface elevation, 1,767.88 feet May 31; minimum daily discharge, 3,000 second-feet 

Feb. 1, during ice period; minimum water-surface elevation, 1,704.97 f 3et Mar. 11.

1929-38: Maximum daily discharge, 90,500 second-feet June 19, 1933; maximum watersurface elevation, 1,767.98 feet June 20, 1933; minimum daily discharge, 1,350 secondfeet Feb. 8, 1936; minimum water-surface elevation, 1,739.59 feet Jan, 25, 1930.

Remarks.- Records of discharge good except those for periods of ice effect, Dec. 10-13, 

24^31, Jan. 1-20, 26-31, Feb. 1 to Mar. 10 (computed on basis of three discharge 

measurements and records for station at Bonners Ferry), and those for period when 

adjacent drainage districts were inundated, May 28-31 (computed on basis of records 

for station at Bonners Ferry and overflow to inundated districts), which are fair. 

Discharge computed from mean elevation-fall-discharge diagram drawn on basis of fall 

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

discharge measurements made at station near Copeland.

Records of water-surface elevations excellent except those for July 14-20, which 

are fair. Elevations affected by backwater from Kootenay Lake.

Drainage districts 7 and 4, adjacent to Kootenai River above this station and 

below station at Bonners Ferry, were inundated on May 27 and 28, respectively.

This station is one of the international gaging stations maintained by the 

United States under agreement with Canada. The records of discharge for water year 

1936-37, as published In Water-Supply Paper 832, have been approved by the Dominion 

Water and Power Bureau, Department of Mines and Resources, Canada.

82 KOOTENAI RIVER BASIN

Kootenal River at Port Hill, Idaho 

(International gaging station)

Location.- Water-stage recorder, lat. 49°00'00", long. 116°30'10", in SWi sec. 8, T. 

65 N., R. 1 W., 300 feet south of international boundary, at Port Hill. Zero of gage 

is 1,700.00 feet above mean sea level, U. S. Coast and Geodetic Survey datum, and 

1,699.80 feet above mean sea level, datum of Geodetic Survey of Canada (adjustment 

Of 1928).

Drainage area.- 13,700 square miles.

Records available.- May to July 1904 and October 1927 to April 1928 (gage heights only), 

April 192B to September 1938 in reports of Geological Survey. October 1924 to 

September 1927 (gage heights only) in reports of Dominion Water and Power Bureau, 

Department of Mines and Resources, Canada.

Average discharge.- 10 years, 14,470 second-feet.

Extremes.- Maximum daily discharge during year, 91,100 second-feet May 29; maximum watersurface elevation, 1,764.08 feet May 31; minimum daily discharge, 3,100 second-feet 

Feb. 1; minimum water-surface elevation, 1,740.65 feet Mar. 11.

1928-38: Maximum daily discharge, 93,200 second-feet June 19, 1933; maximum watersurface elevation, that of May 31, 1938; minimum daily discharge, 1,380 second-feet 

Feb. 8, 1936; minimum water-surface elevation, 1,739.32 feet Jan. 28, 193C. Maximum 

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

Remarks.- Records of discharge good except those for Dec. 10-13, 24-31, Jan. 1-20, 

 26-31, Feb. 1 to Mar. 10, May 28-31, which are fair. Daily discharge,,which represents 

entire flow passing international boundary, obtained by adding tributary inflow, including that of Boundary Creek, to discharge at station near Copeland. Boundary dike of 

Reclamation Farm failed May 31, and breaches continued open during remainder of year. 

Flow through the breaches occurred May 31 to July 2 and was limited to discharge of 

Boundary Creek and part of river flow entering mouth of that creek. Discharge measurements of flow in regular channel and reversed flow entering mouth of Boundary Creek 

are shown for the period.

Records of water-surface elevations excellent. Elevations affected by backwater 

from Kootenay Lake.

Drainage district 10, Severn's Bend district, and Klockmann Boundary Farm adjacent to Kootenai River above this station and below station near Copeland were 

inundated May 29 and 30. River flow diverted into districts at that time gradually 

drained back to river channel as stages receded during succeeding months.

This station is one of the international gaging stations maintained by the United 

States under agreement with Canada. Records of discharge for water year 1936-37 as 

published in Water-supply Paper 832 have been checked and approved by the Dominion 

Water and Power Bureau, Department of Mines and Resources, Canada.

flow was bypassing gage and measuring section through breaks in the boundary dike of 

the Reclamation Farm in Canada. Measurements of reversed river flow through mouth of 

Boundary Creek plus flow passing gaging station on Boundary Creek near Po~t Hill 

represent total flow being bypassed, as U. S. Forest service roadway dike continued intact during period.

Note.- Add 900 feet to obtain elevation abo
OKANOGAN RIVER BASIN 145

Okanogan River near Tonasket, Wash. 

(International gaging station)

Location.- Water-stage recorder, lat. 48°38'00", long. 119°27'50", in lot 3, sec. 8, T. 

36 N., R. 27 E., 1,000 feet upstream from Chewiliken Creek and 5j? miles south of 

Tonasket.

Drainage area.- 7,250 square miles.

Records available.- April 1929 to September 1938.

Extremes.- Maximum discharge during water year 1936-57, 15,100 second-fest June 5 (gage 

height, 14.16 feet); minimum, probably less than 450 second-feet sometime during 

period of ice effect.

Maximum discharge during water year 1937-38, 20,400 second-feet Hay 28 (gage 

height, 16.51 feet); minimum, 486 second-feet Sept. 3 (gage height, 3,96 feet).

1929-38: Maximum discharge, 25,400 second-feet Apr. 27, 1934 (gags height, 18.3 

feet); minimum, 126 second-feet Sept. 5, 1931 (gage height, 3.43 feet).

Remarks.- Records excellent except those for period of ice effect, Dec. 31, 1936, to 

Mar. 9, 1937 (computed on basis of two discharge measurements, gage heights, and 

weather records), those for period of missing gage heights, Dec. 6-14, 1937 (computed on basis of weather records), and those for periods of ice effect, Dec. 23-28, 

1937, Jan. 29 to Feb. 2, Feb. 16-18, 1938 (computed on basis of gage height and 

weather records), all of which are poor. Many diversions for irrigation above station. Flow subject to natural regulation in several lakes, and, as ai aid to navigation, to artificial regulation in Okanagan Lake. Operation of power plant on 

Similkameen River affects low-water flow slightly. This station is o^e of the international gaging stations maintained by the United States under agreement with Canada.

Revision.- Revised figures of discharge for water year 1936-37 supersede those published 

in Water-Supply Paper 832.

Rating tables, water jears 1936-37, 1937-38 except periods of ice e
