SURFACE WATER SUPPLY OF PACIFIC SLOPE BASINS IN WASHINGTON AND UPPER COLUMBIA RIVER

BASIN, 1940

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, 1940. The work was begun in 1888 in connection wltli 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 8,800 gaging stations in the United States 

and also afe many gaging stations In Alaska and Hawaii. In July 1940, 4,760 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 10.

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 11 is the average number of cubic feet of vater 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 

draining 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" 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 34 

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 a feature below the gage that defines the stagedischarge 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 mean dally gage -height to these rating tables gives the 

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

For most of the gaging stations In the area covered by this report the data presented 

comprise a description of the station, a table showing the dally discharge of tt e stream, 

and a table of monthly and yearly discharge and run-off. Skeleton rating tablee 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 speclel 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 diversion? that 

decrease the flow at the gage, artificial regulation from pondage or storage, ard 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-stsge recorder or a nonrecording gage read at the time of the crest. Likewise the minimum discharge represents the lowest stage, unless otherwise qualified. The peak dlschsrge 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 dally 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 dally 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 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 gage-height graph 

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

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 

or fall in a reach of the stream as a factor in the determination of discharge. Information requisite for determining the slope or fall is obtained by means of an auxiliary
GEOLOGICAL SURVEY WATER-SUPPLY PAPEK 902 PLATE 1

B. COLUMBIA RIVER AT GRAND COULEE, WASH.

GAGING-STATION STRUCTURES.
EXPLANATION OF DATA 3

gage set at some distance from the base gage. The auxiliary gage, If one Is used, Is 

described under "Location." 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 occasional winter discharge 

measurements and gage heights, 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.

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 dally discharge. The 

column headed "Maximum" gives the maximum dally discharge and not the Instantaneous discharge when the water surface was at crest stage. 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 RESUUS

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 dally 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 "second-feet per 

square mile" and "run-off In inches" are not published unless storage or diversion records 

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

adjustments can be made for changes in contents 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 *he 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 pr'or 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
4 ACCURACY OF FIELD DATA AND COMPUTED RESULTS

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.- Reports containing records for years after 1901 are given in 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 1940. 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, 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 ireasurements" 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.- Records of daily discharge for many canals and drains in Washington for 1939 and 

earlier years have been collected by the Bureau of Reclamation and the Office of Indian 

Affairs in connection with irrigation and drainage projects. These records have not been 

published. The Soil Conservation Service began in 1932 to make studies of run-off from 

one area of 782 acres and three areas of less than 70 acres each in the vicinity of 

Pullman, Wash., and in 1939 from one area of less than 30 acres in the vicinity of Dayton, / 

Wash. The records are in the files of that organization.
10 COOPERATION

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

Idaho: Department of Reclamation, James Spofford, commissioner. 

Montana: Office of State engineer, E. B. Donohue; State Water Conservation 

Board.

Washington: Department of Conservation and Development, John Brooke Flrk, 

director, and C. J. Bartholet, supervisor of hydraulics, division of water resources; 

cities of Aberdeen, Belllngham, Everett, Seattle, and Tacoma; King and Pierce 

Counties, through the Intercounty River Improvement Commission; and Skaglt and 

Whatcom Counties.

Funds were furnished by the Corps of Engineers, United States Army, for the construction and maintenance of one gaging station in Idaho, five in Montana, and eight 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 Commerce; and 

the Federal Power Commission.

Full cooperation exists between this organization and the Dominion Water end 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:

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.

DIVISION OF WORK

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

Survey, Gienn 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 several States were collected and prepared for publication 

under supervision of district engineers as follows: In Idaho (except for Pend 0-eille 

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

British Columbia, and Kootenai River near Rexford, Mont., T. R. Newell; In Montana (except 

for the two stations noted above), A. H. Tuttle; In Washington and for Pend Orellle River 

at Priest River, Idaho, G. L. Parker until October 17, 1939, Succeeded by F. M. Veatch.

The records were reviewed and the manuscript prepared for publication-under «e direction of B. J. Peterson, engineer In charge, and M. C. Boyer, associate engineer, 

section of reports.

Cedar River near Landsberg, Wash.

Location.- Water-stage recorder, lat. 47°23'35", long. 121°56'50", In sec. 17, T. 22 N., 

K. 7 E., If 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 (including that of Rock Creek).

Records available.- April 1914 to September 1940. July 1895 to September 1898 (at site 

2 miles downstream, published as Cedar River at Clifford Bridge, near Ravensdale, 

Wash.), and March 1901 to April 1912 (at site of Seattle water-supply Intake, published as Cedar River near Ravensdale, Wash.) In reports of Geological Survey; August 

1895 to April 1912 and May 1914 to September 1933 (monthly discharge) in State WaterSupply Bulletin 5. Records as originally published for water years 1932-33 and 1933- 

34 did not include flow of Rock Creek; revised figures of yearly discharge for these 

years including estimated flow of Rock Creek were published In Water-Supply Paper 882.

Average discharge.- 42 years (1895-1911, 1914-40), 698 second-feet (adjusted for Rock 

Creek diversion since October 1932).

Extremes.- Maximum discharge during year, 1,880 second-feet (regulated) Mar. 7 (gage 

height, 3.43 feet); minimum, 237 second-feet (regulated) Sept. 30 (gage height, 0.99 

foot).

1895-98, 1901-12, 1914-40: Maximum discharge observed, 13,600 second-feet Nov. 

19, 1911 (gage height, 9.7 feet, site and datum then In use); minimum discharge, 83 

second-feet Sept. 19, 1898.

Remarks.- Records excellent. All diversions except Rock Creek returned to river above 

station. Rock Creek which enters naturally Just above gage has been diverted to a 

point downstream from Seattle municipal water-supply intake to lessen danger of 

pollution. Monthly discharge adjusted for diversion estimated on basis of five discharge measurements, and relation of flow of Rock Creek to difference In discharge 

between records of Cedar River at Cedar Falls and near Landsberg. Flow of river 

partly regulated by Cedar Lake.

Cooperation.- Gage-height record collected in cooperation with city of Seattle.

Discharge, In second-feet, water year October 1939 to September 1940

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

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

Remarks.- Records excellent. Water Is diverted 3 miles upstream (may be entire low 

flow) and Is returned to river at Seattle power plant Just ?.bove station. Flow 

also partly regulated by Dlablo Reservoir and Ruby Reservoir (see p. 63 ).

Cooperation.- Gage-height record collected In cooperation with, and four discharge 

measurements furnished by city of Seattle.

UNITED STATES DEP.C TJENT OP THE INTERIOR
62 SKAGIT RIVER BASIN 

Skagit River near Concrete, Wash.

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

tTETyat dalles 2 miles downstream from Baker River and 2& miles southwest of Concrete. 

Datum 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^

Kecords available.- September 1924 to September 1940.

Average aiscnargeT- 16 years, 14,340 second-feet (adjusted for storage In Lake Shannon 

Reservoir since October 1925, Diablo Reservoir since October 1929, and Ruby Reservoir 

since March 1940).

Extremes.- Maximum discharge during year, 48,200 second-feet (regulated) Dec. 15 (gage 

height, 25.70 feet); minimum, 3,830 second-feet (regulated) Oct. 2 (gage height, 

13.68 feet).

1924-40: 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. l->24, 

1925^ when recorder was not operating and gates in Baker River Dam were first closed.

Maximum stage known 69.3 feet, present datum from floodmarks (discharge, 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 except those for periods of no gage-height record, which are 

poor. All diversions returned to river above gage. At low stages flow partly 

regulated by power plants on Baker and upper Skagit Rivers, and by Ruby, Diablo, 

and Lake Shannon Reservoirs. Records of daily discharge not adjusted for change in 

contents of reservoirs.

38 N., R. 3 E., in Whatcom Falls State Park three-quarters of a mile downstream from 

Lake Whatcom, and 2 miles east of Bellingham. Prior to Sept. 18, 1939, staff gage at 

same site and datum. Datum of gage is 200.00 feet above mean sea level (city of Bellingham datum). Former gage at site about half a mile upstream at different datum.

Drainage area.- 56 square miles (revised).

Records available.- November 1910 to September 1914 (gage heights only October 1912 to 

September 1914), July 1939 to September 1940.

Extremes.- 1939 (regulated): Maximum daily discharge during period July to September, 

120 second-feet Sept. 30; minimum daily discharge, 0.7 second-foot July 13.

1939-40 (regulated): Maximum discharge during year, 412 seccnd-feet Mar. 16 (gage 

height, 87.88 feet); Minimum, 0.7 second-foot Aug. 16, 1940 (gage height, 84.85 feet); 

minimum daily, 0.9 second-foot Oct. 2, 5, 8-12.

Feb. 3, 1937 (gage height, 6.27 feet, site and datum then in use).

Remarks.- Records excellent except those for period of no gage-height record, which are 

good. Small amount of water diverted above station for Irrigation. Slight fluctuation at low water caused by power plant on Kootenai River. Flow affected by natural 

storage In numerous lakes and by artificial regulation in Kootenai River Basin.

Cooperation.- This station Is one of the International gaging stations maintained by 

Canada under agreement with the United States.

OF THE INTERIOR
COLUMBIA RIVER MAIN STEM 7'

Columbia River at International boundary 

(International gaging station)

Location.- Water-stage recorder, lat. 49°00'03", long. 117°37'40", In SEi sec. 4, T. 40 

N. , R. 41 E., at the International boundary, half a mile downstream from Pend Orellle 

River. Datum of gage Is at mean sea level (Bureau of Reclamation 1937 datum). Prior 

to Apr. 27, 1939, staff gage at same site and datum.

Drainage area.- 59,700 square miles.

Records available.- March 1938 to September 1940.

Extremes .- 1938:

second-feet June 27, 28 (elevation, 1,324.00 fee 

feet Mar. 26 (elevation, 1,293.52 feet).

1938-39: Maximum discharge during water year, 259,600 second-feet May 31, June 1 

(elevation, 1,318.95 feet); minimum observed, 21,600 second-feet Feb. 10 (elevation, 

1,290.12 feet).

1939-40: Maximum discharge during water year, 248,000 second-feet May 30 (elevation, 1,317.98 feet); minimum, 25,200 second-feet Jan. 26 (elevation, 1,290.92 feet).

Flow probably as low as 12,900 second-feet occurred during January'1930, based on 

Information from other gaging stations (elevation, 1,288.1 feet, froni rating curve extended below 1,291.6 feet).

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

good. Many diversions above gage for Irrigation but quantity very small percentage 

of flow past gage. Some fluctuation at low stage caused by power plant on Kootenal 

River. Flow affected by natural storage In several lakes and by artlflcal regulation 

In Kootenal and Pend Orellle River Basins.

Cooperation.- This Is one of the International gaging stations maintained by the United 

atates under agreement with Canada.

80 COLUMBIA RIVER MAIN STEM

Columbia River at Kettle Falls, Wash.

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

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

River'. Datum 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 1940.

Average discharge?- 27 years, 98,750 second-feet.

Extremes .- Maximum discharge during year, 278,200 second-feet June 2 (elevation, 1,190.45

 feet); minimum, 26,400 second-feet Jan. 27 (elevation, 1,167.67 feet).

1913-40: 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, 193/.

Maximum discharge known, 700,000 second-feet during flood of 1894 (based on information from several sources). 

Remarks.- Records excellent except those for periods of ice effect or no gage-height rec-

 ord, which are good. Many diversions upstream from gage for irrigation, but quantity 

diverted is very small percentage of flow past gage. Slight fluctuation at extreme 

low water caused by power plant on Kootenai River. Flow affected by natural storage 

in many lakes and by artificial regulation in Kootenai and Pend Oreille River Easins.

Rating table, water year 1939-40 except period of ice effect (gage height, in feet, 

and discharge, in second-feet)

feet); minimum, 27,300 second-feet (regulated) Jan. 28, 29 (elevation, 935.08 feet). 

1913-40: 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 known, 725,000 second-feet during flood of June 1894 (estimated).

Remarks.- Records excellent. Diversion above station for irrigation is small percentage 

or now past gage. Some diurnal fluctuation caused by power plants on Spokane River 

and by construction at Grand Coulee Dam. Flow affected by natural storage in many 

lakes and by artificial regulation in Kootenai, Pend Oreille and Spokane River Basins 

and at Grand Coulee Dam.

COLUMBIA RIVER MAIN STEM

Columbia River at Trinidad, Wash.

Location.- Water-stage recorder, lat. 47°13'30", long. 120°00'50", in SEi sec. 13, T. 20 

N. , R. 22 E., half a mile southwest of Trinidad, 8i miles downstream from Cclocham 

Creek, and 12 miles downstream from Rock Island Dam. Datum of gage is 500 feet above 

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

Drainage area.- 89,700 square miles.

Records available.- October 1930 to September 1940. January to December 1910 (gage

heights only), and May 1913 to December 1916 at sites about 1 mile above am? at highway bridge at Wenatchee, 24 miles upstream, published as Columbia River at Wenatchee, 

Wash.; January 1917, at Beverly, 29 miles downstream; January 1917 to September 1930, 

at site half a mile north of Vernita, 50 miles downstream, published as Columbia River 

at Vernita, Wash.

Average discharge.- 27 years, 117,200 second-feet (adjusted for Columbia River Reservoir 

beginning October 1939 ) .

Extremes.- Maximum discharge during year, 274,000 second-feet June 5 (gage height, 41.88 

feet); minimum, 26,000 second-feet (regulated) Jan. 31 (gage height, 17.43 feet).

1913-40: Maximum discharge, 528,000 second-feet June 15, 16, 1913 (gage height, 

45.7 feet, site and datum then in use); minimum, 4,120 second-feet (regulated) Feb. 

10, 1932 (gage height, 11.40 feet).

Maximum discharge known, about 740,000 second-feet June 7, 1894.

Remarks.- Records excellent. Considerable water diverted above gage for irrigation but 

quantity small in proportion to flow past gage. Some diurnal fluctuation caused by 

power plant at Rock Island and by construction at Grand Coulee Dam. Flow affected by 

natural storage in numerous lakes and by artificial regulation in Kootenai, Pend 

Oreille, Spokane, Okanogan, and Chelan River Basins, and at Grand Coulee Dam.

UMITED STATES DEPARTMENT OF THE INTERIOR 

Qeolog il Survey
KOOTENAI RIVER BASIN 93

Kootenai River near Copeland, Idaho 

(International gaging station)

Location.- Water-stage recorder, lat. 48°54'45", long. 116°25'00", in NV'iNWiSWi sec. 12, 

T. 64 N., -R. 1 W., at Andrews Ranch, three-quarters of a mile downstream from Mission 

Creek and li miles northwest or Copeland. Datum of gage is 1,700.00 feet above mean 

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

Drainage area.- 13,400 square miles.

Records available.- October 1927 to September 1940 (gage height record only prior to

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

only) in reports of Dominion Wager and Power Bureau, Department of Mines and Resources, 

Canada.

Average discharge.- 11 years (1929-40), 13,850 second-feet.

Extremes.- Maximum daily discharge during year, 53,400 second-feet May 27; maximum

elevation, 1,759.37 feet May 27; minimum daily discharge, 2,070 secord-feet Jan. 24, 

during ice period; minimum elevation, 1,740.97 feet Mar. 18.

1929-40: Maximum daily discharge, 90,500 second-feet June 19, 1933; maximum 

elevation, 1,767.98 feet June 20, 1933; minimum daily discharge, l,3fO second-feet 

Feb. 8, 1936, during Ice period; minimum elevation, 1,738.94 feet Mar. 18, 1939.

Remarks.- Records of discharge good except those for periods of ice effect, 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 end station at 

Port Hill, and discharge measurements made at stations near Copeland and at Port Hill. 

Stage-discharge relation affected by backwater from Kootenay Lake.

Cooperation.- This station is one of the international gaging stations maintained by 

the United States under agreement with Canada.

UNITED STATES DEPAD'"MENT OF THE INTERIOR 

Oeolog al Survey
KOOTENAI RIVER BASIN £

Kootenai 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. Datum 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),

 and April 1928 to September 1940 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.- 12 years (1928-40), 14,020 second-feet.

Extremes.- Maximum daily discharge during year, 54,600 second-feet May 26, 27; maximum

 elevation, 1,756.49 feet May 27; minimum daily discharge, 2,140 seccnd-feet Jan. 24; 

minimum elevation, 1,740.66 feet Mar. 20.

1928-40: Maximum daily discharge, £3,200 second-feet June 19, 1S33; maximum 

elevation, 1,764.08 feet May 31, 1938; minimum daily discharge, 1,380 second-feet 

Feb. 8, 1936; minimum elevation, 1,738.69 feet Mar. 18, 1939.

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

Remarks.- Records of discharge good except those for periods of ice effect at station

 near Copeland, which are fair. Daily discharge, which represents tte entire flow 

passing international boundary, computed by adding tributary inflow, including that 

of Boundary Creek, to flow at station near Copeland. Boundary dike of Reclamation 

Farm and Forest Service roadway dike (south side of Boundary Creek) remained intact 

and flow of river was confined throughout the year to main channel upon which gage 

and cableway are located. Elevations affected by backwater from Kootenay Lake.

Cooperation.- This station is one of the international gaging stations maintained by

 the United States under agreement with Canada.

Note.- Monthly figures showing discharge in second-feet per square mile and run-off in inches are 

not published, owing to regulation by Coeur d'Alene Lake. The yearly figures represent more nearly 

the natural flow. No gage-height record Jan. 24 to Feb. 1, Feb. 19 to 28, Mar. 1-17; discharge 

computed on basis of unpublished records collected by Washington Water Power Co. aid station at 

Spokane, Wash.

Remarks.- Records excellent except those for October to January and July to September, 

which are ~ood. Water diverted above station for irrigation. Flow affected considerably by regulation for power and by storage in Coeur d'Alene Lake. Capacity of Coeur 

d'Alene Lake between elevations 2,117 and 2,135 feet, 770,000 acre-feet. Capacity of 

Long Lake between elevations 1,512 and 1,531 feet, 79,600 acre-feet.

Cooperation.- Gage-height record collected in cooperation with Washington Water Power Co., 

which also furnished some discharge measurements and gage heights for Long Lake.

Discharge, in second-feet, water year October 1939 to September 1°40

a Ho gage-height record; discharge computed by Washington Water Power Co. engineers from record of 

tail race gage heights at the Little Falls power plant and turbine ratings.

t Sunday.

Rote.- Contents of Coeur d'Alene Lake based on mean gage heights for last day of each month, and 

for Long Lake on midnight gage readings.
166 SPOKANE RIVER BASIN

St. Joe River at Calder, Idaho

Location.- Water-stage recorder, lat. 47°16', long. 116°11', In sec. 3, T. 45 N., R. 2 

 E., 150 feet southwest of Chicago, Milwaukee, St. Paul & Pacific Railway strtion at 

Calder. Altitude of gage, about 2,100 feet above mean sea level.

Drainage area.- 1,080 square miles.

Records available.- July 1920 to September 1940. April 1911 to September 1912, at station 2S miles downstream.

Average discharge.- 20 years (1920-40), 2,274 second-feet.

Extremes.- Maximum discharge during year, 8,140 second-feet May 11 (gage height, 85.21 

reet); minimum discharge recorded, 216 second-feet Nov. 17 (gage height, 78.98 feet).

1911-12, 1920-40: Maximum discharge, 53,000 second-feet Dec. 23, 1933, computed 

on basis of slope between gages downstream; maximum gage height, 93.1 feet Apr. 18, 

1938, from floodmark; minimum discharge, 96 second-feet Dec. 5, 1928 (gage 1-eight, 

78.43 feet).

Remarks.- Records good except those for period of Ice effect, which are fair. No dlverslon above gage. Operation of splash dam on Marble Creek causes some diurnal fluctuation during log-driving season.

Cooperation.- Gage-height record and results of six discharge measurements furrished by 

Washington Water Power Co.

upstream from mouth, and 11 miles northeast of Chiwaukum. Datum of gage is 2,100 

feet above mean sea level (from river-profile map).

Drainage area.- 169 square miles.

Records available.- August 1936 to September 1940. May 1911 to October 1914, at site 4 

miles downstream, published as Chiwawa Creek near Leavenworth.

Extremes.- Maximum discharge during year, 2,540 second-feet May 24 (gage height, 7.14 

feet); minimum, 79 second-feet Sept. 24, 25, 26 (gage height, 3.80 feet).

1911-14, 1936-40: Maximum discharge recorded, 3,210 second-feet May 25, 26, 1938 

(gage height, 7.66 feet); minimum recorded, 67 second-feet Nov. 28, 1S36 (gage height, 

3.74 feet), but may have been less during periods of ice effect.

Remarks.- Records excellent except those for periods of ice effect and nc gage-height 

record, which are poor, and those computed on basis of shifting-control method, which 

are good. No diversion or regulation.
