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, 1942. The work was begun In 1888 In connection with 

special studies relating to Irrigation. Measurements of the flow of streams and of the 

stage and contents of lakes and reservoirs have been made at about 9,400 gaging stations 

In the United States and also at many gaging stations In Alaska and Hawaii. In July 1942, 

4,970 gaging stations were being maintained by the Geological Survey and cooperating 

organizations. Miscellaneous discharge measurements were made at many other points.

In the execution of the work many state and private organizations have cooperated, 

either by furnishing data or by assisting In collecting data. Cooperation of the first 

kind Is acknowledged In connection with the description of each station affected; cooperation of the second kind Is acknowledged on page 11.

DEFINITION OF TERMS

The units In which stream-flow data are_presented In this repprt and other terms used 

herein are defined as follows: c

"Second-feet" Is an abbreviation for "cubic feet per second.", A second-foot Is the 

rate of discharge of a stream whose channel Is 1 square foot in cross-sectional area and 

whose average velocity Is 1 foot per second. ; ,

"Second-feet per square mile" Is the average number of cubl« 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 

dralnjng from It In a given period were uniformly distributed on its eurface. 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 24 

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

represents s run-off of 0.0372 inch from 1 square mile.

"Stage-discharge relation" Is an abbreviation for the term "relation between gage 

height and discharge."

"Control" Is a term used to designate a feature downstream from the gage that determines 

the stage-discharge relation at the gage. This feature may be a natural section, a reach 

of the channel, or an artificial structure.
2 SURFACE WATER SUPPLY, 1942, PART 12

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 

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. Structures In use at gaging stations are shown on plates 1 and 2.

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

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

If the stage-discharge relation is subject to change because of frequent or continual 

change In the physical features that form the control, the dally mean discharge Is determined by the "shifting-control method," In which correction factors based on Individual 

discharge measurements and notes by engineers and observers are used In applying the gage 

heights to the rating tables. At times the stage-discharge relation for a station may be 

temporarily changed by the presence of aquatic growth or debris on the control.. For such 

times the dally mean discharge Is computed by what Is essentially the "shifting-control" 

method, described above.

At some gaging stations the stage-discharge relation is affected by backwater from 

reservoirs, tributary streams, or other sources", which necessitates the use of the "slope 

method," In which the slope or fall in a reach of the stream is a factor in the determination of discharge. Information requisite for determining the slope or fall is obtained 

by means of an auxiliary gage set at some distance from the base gage. At some stations 

the stage-discharge relation is affected by changing stage, and for them the rate of 

change of stage is used as a factor in the determination of discharge.

At most gaging stations In the northern part of the United States and at some in the 

mountainous regions of other parts the stage-discharge relation is affected by ice during 

the winter, which makes It impossible to compute the discharge in the usual manner. Discharge for periods of Ice effect Is computed on the basis of the gage-height record and 

occasional winter discharge measurements, consideration being given to the available Information on temperature and precipitation, notes by gage observers and engineers, and 

comparable records of discharge for stations in the same or nearby basins. The days 

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

or are given in a general note following the table.

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

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

the stream, and a table of monthly and yearly discharge and run-off, skeleton rating 

tables are published for all stations except those at which the daily discharge for the 

greater part of the year was determined by the shifting-control method, the slope method, 

or other special methods.

The description of the station gives the type of gage, Its latitude and longitude 

determined from the best available maps, and information in regard to diversions that

decrease the flow at the gage, artificial regulation from pondage or storage, and the 

accuracy of the records. Under "Average discharge" le given the average discharge for the 

number of years indicated. It Is given only for stations for which there are 10 or more 

complete years of record. Under "Extremes" are given the maximum discharge and gage 

height; the minimum discharge if there is little or no regulation; the minimum dally discharge If there is extensive regulation (also the minimum discharge if useful); and the 

minimum gage height (unless It Is of no Importance). Unless otherwise qualified, the 

maximum discharge corresponds to the crest stage, obtained by use of a water-stage 

recorder or a nonrecording gage read at the time of the crest. Likewise the minimum discharge represents the loweet stage, unless otherwise qualified. Selected peak discharges

with the times of their occurrence are given below the table of monthly discharge for some

/

stations. This supplementary Information ie generally omitted for stations having drainage areas of less than 10 square miles or more than 10,000 square miles or If the peak 

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

percent.

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

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

twice-daily readings. For flashy floods the daily mean discharge is determined from gageheight graphs based on gage readings made once or twice dally or oftener, as stated in the 

station description. For etations equipped with water-stage recorders, except those on 

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

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

gage height may not Indicate the true dally mean discharge, which must be obtained by 

averaging the discharge for parts of the day or by using the discharge Integrator, an 

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

containing as an essential element a curve representing the stage-discharge relation at ( 

the station.

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

for each month of the figures given In the table of dally discharge. The column headed 

"Maximum" gives the maximum daily discharge and not the momentary discharge when the water 

surface was at crest stage. Likewise, in the column headed "Minimum" the quantity given 

is the minimum dally tliecharge. The column headed "Mean" gives the average flow in cubic 

feet per second during the month.

For most gaging etations on lakes and reservoirs the data presented comprise a description of the station and a monthly summary table of stage and contents. For some reservoirs 

a table showing dally contents Is given. A skeleton table of capacity at given stages Is 

usually given in the 1'irst report in which data for a station are published but is omitted 

from succeeding reports.

TIME BASIS

At 2 a.m. on February 9, 1942, as an emergency measure, the Nation shifted from 

standard time to "war time," and clock time in the several zones of the country was moved 

ahead 1 hour, or to Z a.m. This made February 9 a 23-hour day. Time prior to 2 a.m.
4 SURFACE WATER SUPPLY, 1942, PART 12

February 9 as given herein refers to standard time; time after 2 a.m. February 9 refers 

to war time. To convert war time to standard time, subtract 1 hour.

Records of daily discharge prior to February 9, 1942, published herein have been computed on the basis of standard time. Records subsequent to that date have been computed 

on the basis of war time. The discharge given for February 9 is the mean for 23 hours. 

The mean discharge and run-off for the month of February have been computed from the total 

second-foot-days for the month without adjustment for the fact that February 9 was a 

23-hour day. The small error resulting from this procedure has been disregarded.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of etream-flow data depends primarily on (1) the permanency of the stagedischarge relation or, if the control is unstable, the frequency of discharge measurements 

and (2) the accuracy of observations of stage, measurements of flow, and Interpretation 

of recojrds.

The station description gives a statement in regard to the general accuracy of the 

records. "Excellent" indicatee 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. The records of monthly and yearly mean discharge and run-off are, in 

general, more accurate than the daily records.

Yield at some stations as indicated by monthly means may vary widely from natural yield, 

owing to diversion, consumption, regulation by storage, increase or decrease in evaporation due to artificial causes, or other factors. For such stations figures of "secondfeet per square mile" and "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 noncontributing areas or if the 

average annual rainfall over the drainage area is less than 20 inches.

Many gaging stations on streams in the irrigated areas of the United States are situated 

above most of the diversions from those streams, and therefore the discharge recorded does 

not show the water supply available for further development, as prior appropriations below 

the station roust first be satisfied.

The table of monthly discharge presents in summary the distribution of the flow past 

the station. The table of dally discharge affords opportunity for more detailed studies 

of the variation in flow. As further observations in each succeeding year may be expected 

to throw new light on data previously published, it should be borne in mind that such data 

are subject to revision in succeeding water-supply papers.

Papers on surface water supply containing records from 1899 to date, grouped by years 

and drainage basins, are listed by number on page 7. Hie data for any particular 

station will, in general, be found In the reports covering the years during which the 

station was aalntained. 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, md 503, which contain records for the Ohio River Basin for those years.

The records at most of the stations discussed In these reports extend over a series of 

years. Miscellaneous measurements at many points other than regular gaging stations have 

been made each year and are published under "Miscellaneous discharge measurements" at the 

end of each report, the streams and points of measurement listed appearing In the same 

relative order as the streams and gaging stations In the body of the report. An Index of 

the records obtained prior to 1904 has been published In Water-supply Paper 119.

Each of the reports on surface water supply for the year 1939, Issued as Water-Supply 

Papers 871 to 884 (see table on p. 7), contains a summary of yearly discharge at gaging 

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

also as separate reprints.

10 SURFACE WATER SUPPLY, 1942, PART 12

The reports listed in the foregoing tables contain the customary records of discharge 

collected during the systematic operation of gaging stations. Detailed Information on 

the stage and discharge of many streams during major floods has been included in special 

reports on these floods published by the Geological Survey. The more recent of these 

reports also contain other pertinent hydrologic information and analyses and compilations 

of data relating to earlier noteworthy floods. The following list gives the numbers and 

titles of these reports.

t Records for earlier years published in water-supply papers of Geological Survey.

Note.- Records of daily discharge for many canals and drains in Washington for 1942 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 about 700 acres and three areas of less than 70 acres each in vicinity of 

Pullman, Wash., and in 1939 from one area of 19.2 acres in vicinity of Dayton, Wash. The 

records are In the files of that organization. The Northern Rocky Mountain Forest and 

Range Experiment Station collects run-off records from an area of 960 acres on Benton 

Creek near Priest River, Idaho.
SURFACE WATER SUPPLY, 1942, PART 12 13- 

( COOPERATION

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

Idaho: State Department of Reclamation, E. V. Berg, commissioner. 

Montana: Office of State engineer, F. E. BUck; state Water Conservation 

Board.

Washington: Department of Conservation and Development, Ed Davis, director, 

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

Department of Fisheries, F. J. Foster, director; Department of Game, B. T. 

McCauley, director; cities of Aberdeen, Bellingham, Everett, Seattle, and Tacoma; 

King and Pierce Counties, through the Intercounty River Improvement Commission; 

and Skaglt and Whatcom Counties.

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

the operation of one gaging station in Idaho, five in Montana, and ten in Washington.

Acknowledgment of financial assistance in collecting records published herein is due 

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

Affairs, United States Department of the interior; Forest Service and Soil Conservation 

Service, United States Department of Agriculture; Weather Bureau, United States Department 

of Commerce; and the Federal Power Commission.

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 wac also rendered by the following municipalities, 

corporations, and individuals:

Idaho: Washington Water Power Co. 

Montana: Montana Power Co.

Washington: Crown Zellerbach Corporation; Electric Land Co.; Puget Sound Power 

& Light Co.; and Washington water Power Co.

DIVISION OF WORK

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

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

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

data for the stations in the several States were collected and prepared for publication 

under supervision of district engineers as follows: In Idaho and for dark Fork near 

Heron, Mont., T. R. Newell; in Montana (except for station noted above), A. H. Tuttle; in 

Washington, F. M. veatch.

The records were reviewed and the manuscript prepared-for publication under the direction of B. J. Peterson, engineer in charge, and J. w. Garat^rell, assistant engineer,

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

Drainage area.- 138 square miles (including that of Rock Creek).

Records available.- October 1898 to April 1901, April 1914 to September 1942. July 1895 

to September 1098 (at site 2 miles downstream, published as Cedar River at Clifford 

Bridge, near Ravensdale), and March 1901 to April 1912 (at site of Seattle water-supply 

Intake, published as Cedar River near Ravensdale); records equivalent.

Average discharge.- 44 years (1895-1911, 1914-42), 688 second-feet (adjusted for Rock Creek 

diversion since October 1932).

Extremes.- Maximum discharge during year, 1,830 second-feet (regulated) Dec. 19 (gage 

height, 3.42 feet); minimum, 234 second-feet (regulated) Sept. 27 (gage height, 0.98 

feet).

1895-98, 1901-12, 1914-42: Maximum discharge observed, 13,600 second-feet Nov. 19, 

1911 (gage height, 9.7 feet, site and datum then In use); minimum observed, 83 secondfeet Sept. 19, 1898.

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

station. Rock Creek which entered naturally just above gage has been diverted to a 

point downstream from Seattle municipal water-supply Intake to lesson danger of pollution. Monthly discharge adjusted for diversion estimated on basis of ten 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.

74 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. Datum of gage is 400 feet above mean sea level, subject to correction to datum 

of 1929.

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 1942 in reports 

of Geological Survey. October 1913 to September 1920 (monthly discharge only) in State 

Water-supply Bulletin 5.

Average discharge.- 34 years, 4,298 second-feet (adjusted for storage in Diablo Reservoir 

since October 1929 and Ruby Reservoir since March 1940).

Extremes.- Maximum discharge during year, 17,400 second-feet (regulated) May 26 (gage 

height, 88.14 feet); minimum, 216 second-feet (regulated) Mar. 22 (gage height, 78.96 

feet);-minimum daily, 836 second-feet (regulated) Mar. 22.

1908-14, 1920-42: 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 daily, 136 second-feet (regulated) Aug. 24, 1930.

Remarks.- Records excellent. Water is diverted 3 miles upstream (maj? be entire low flow) 

and is returned to river at Seattle power plant Just upstream from station. Flow partly 

regulated by Diablo and Ruby Reservoirs (see p. 77 ), having a combined capacity of 

179,100 acre-feet.

Cooperation.- Gage-height record collected in cooperation with and many discharge measure 

ments furnished by city of Seattle.

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

Datum of gage Is 130.0 feet above mean sea level, datum of 1929.

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

Records available.- September 1924 to September 1942.

Average discharge.- 18 years, 14,020 second-feet (adjusted for storage In Lake Shannon 

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

since March 1940).

Extremes.- Maximum discharge during year, 76,300 second-feet Dec. 2 (gage height, 30.17 

feet); minimum, 3,130 second-feet (regulated) Sept.-27 (gage height, 13.19 feet); 

minimum dally, 3,940 second-feet (regulated) Sept. 28.

1924-42: 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 period 

Oct. 1-24, 1925, when recordsr was not operating and gates In Baker River Dan were 

first closed; minimum dally recorded, 2,610 second-feet (regulated) Nov. 14, 1936.

Maximum stage known, 69.3 feet, present datum, frort 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 good except those for period of no gage-height record, which are fair. 

All diversions returned to river above gage. Flow partly regulated by power plants 

on Baker and upper Skaglt Rivers, and by Ruby, Diablo and Lake Shannon Reservoirs 

(see p. 77 ). Records of dally discharge not adjusted for change in contents of 

reservoirs.

92 COLUMBIA RIVER MAIN STEM

Columbia River at Grand Coulee, Wash.

Location.- Water-stage recorder, lat. 47°58'00*, long. 118°58'45", opposite lot 4, sec. 

36, T. 29 N., R. 30 E,, In _pler_3 of highway bridge at Grand Coulee, 2,500 feet downstream from Grand Coulee Dam and 14 miles upstream from Nespelem River. Datum of gage 

Is at mean sea level, datum of 1929.

Drainage area.- 74,100 square miles.

Records available}- April 1913 to September 1942 (monthly discharge only, April 1913 to 

June 1923, Japuary 1924 to May 1928).

Average discharge.- 29 years, 106,400 second-feet, adjusted for storage In Columbia River 

Reservoir beginning October 1939.

Extremes.- Maximum discharge during year, 315,100 second-feet (regulated) June 13 (elevatlon, 969.16 feet); minimum, 34,200 second-feet (regulated) Mar. 1 (elevation, 936.74 

feet).

1913-42: 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 (estimated) during flood of June 1S94.

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

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

and by regulation at Grand Coulee Dam. Flow affected by natural storage In many lakes 

and by artificial regulation in Kootenal, Pend Orellle and Spokane River Basins and 

In Columbia River Reservoir at Grand Coulee Dam (see preceding page).

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

mean sea level, subject to correction to 1929 datum.

Drainage area.- 89,700 square miles.

Records available .-. October 1930 to September 1942. January to December 1910 (gage heights 

only), May 1913 to December 1916, at sites about 1 mile above and at highway bridge at 

Wenatchee, 24 miles upstream, published as Columbia River at Wenatchee; January 1917, 

at Beverly, 29 miles downstream; January 1917 to September 1930, at site half a mile 

north of Vernlta, 50 miles downstream, published as Columbia River at Vernita.

Average discharge.- 29 years, 116,100 second-feet (adjusted for storage in Columbia River 

Reservoir Beginning October 1939).

Extremes.- Maximum discharge during year, 321,000 second-feet June 16 (gage height, 44.50

Maximum discharge known, about 740,000 second-feet June 7, 1894 (based on Information obtained at other points).

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

quant1ty 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 Orellle, 

Spokane, Okanogan, and Chelan River Basins, and in Columbia River Reservoir (see p. 91).

* Winter discharge measurement made on this day.

Hote.- Channel conveyance affected by Ice Dec. 27 to Mar. 31; discharge computed on basis of four 

discharge measurements and records for station at Bonners Ferry, intervening inflow, and channel 

storage.

Time basis; Pacific standard time prior to 2 a.m., Feb. 9, 1942; Pacific war time thereafter. 

To convert war time to standard tine, subtract 1 hour.

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., 

RTlw., 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.- Hay to July 1904, October 1927 to April 1928 (gage heights only) and 

April 1928 to September 1942 in reports of Geological Survey. October 1984 to September 

1927 (gage heights only) In reports of Dominion Water and Power Bureau, Department of Mines and Resources, Canada.

Average discharge.- 14 years, 14,000 second-feet.

Extremes.- Maximum dally discharge during year, 81,900 second-feet nay 28; maximum elevation, 1,760.58 feet May 29; minimum dally discharge, 3,440 second-feet Feb. 24; minimum elevation, 1,740.21 feet Apr. 1.

1928-42: Maximum dally discharge, 93,200 second-feet June 19, 1933; maxljatm elevation, 1,764.08 feet May 31, 1938; minimum dally discharge, 1,380 second-feet Feb. 8, 

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

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

Remarks.- Records good except those for period of ice effect at Copeland, which are fair. 

Daily discharge represents 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 slJe 

of Boundary Creek) remained intact and flow of river was confined throughout year to 

main channel on 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 

United States under agreement with Canada.

Location.- Water-stage recorder, lat. 47°16", long. 116 0 11', in sec. 3, T. 45 N., R. 2 

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

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

Drainage area.- 1,080 square miles.

Records available.- July 1920 to September 1942. April 1911 to September 1912 at site 

2t miles downstream.

Average discharge.- 22 years (1920-42), 2,208 second-feet.

Extremes.- Maximum discharge during year, 10.400 second-feet Dec. 3 (gage height, 85.99 

feet); minimum, 358 second-feet Sept. 30 \gage height, 79.40 feet).

1911-12, 1920-42: 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 height, 

78.43 feet).

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

Cooperation.- Gage-height record and nine discharge measurements furnished by Washington 

Water Power Co.
