SCOPE OF WORK

This volume is one of a series of 18 reports presenting measurements of stage, discharge, and content of streams, lakes, and reservoirs in the United States during the 

water year ending September 30, 1952. Since 1888, when the United States Geological 

Survey first studied streamflow in relation to problems of irrigation, similar measurements have been made at more than 12,600 gaging stations in the 48 States and"at many 

others in the Territories of Alaska and Hawaii. On September 30, 1952, the Geological 

Survey and cooperating organizations were maintaining 6,700 gaging stations, including 

those in Alaska and Hawaii. Miscellaneous discharge measurements were made at many other 

points in the 1952 water year.

COOPERATION

Many State, municipal, and private organizations have cooperated with the Geological 

Survey in this work by either furnishing or helping to collect data. Organizations that 

supplied data are acknowledged in station descriptions, and organizations that assisted 

in the collection of data through cooperative agreements with the Survey are:

Idaho: Idaho Department of Reclamation, M. R. Kulp, State reclamation engineer. 

Montana: Office of State Engineer, F. E. Buck; State Water Conservation Board. 

Washington: State Department of Conservation and Development, W. A. Galbraith, 

director, and C. J. Bartholet, supervisor of hydraulics for the department; State 

Department of Fisheries, R. J. Schoettler, director; State Department of Game, 

D. W. Clarke, director; State Department of Highways, W. A. Bugge, director; cities 

of Bellingham, Bremerton, Eyerett, Olympia, Seattle, and Tacoma; Intercounty River

Oreille County Public Utility District No. 1; Douglas, Grant, Pend Oreille, Skagit, 

and Whatcom Counties, and Diking District No. 2 of Pend Oreille County. 

Assistance in the form of funds or services was given by the Corps of Engineers, Department of the Army, in collecting records published herein for 4 gaging stations in 

Idaho, 4 in Montana, and 13 in Washington.

Assistance was also furnished by the Soil Conservation Service of the United States Department of Agriculture, the United States Department of the Army, the Weather Bureau of 

the United States Department of Commerce, Bureau of Reclamation and the Office of Indian 

Affairs'Of the United States Department of the Interior, and the United States Department 

of State. Acknowledgment is due to the Forest Service of the United States Department of 

Agriculture and the Weather Bureau for occupation permits and furnishing special reports 

of watershed conditions and precipitation records.

Full cooperation exists between the Geological Survey of the United States Department 

of the Interior and the Water Resources Division, Department of Resources and Development, 

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

190S, 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 Und available in either country. These stations are herein designated "international 

gaging stations."

The following organizations aided in collecting records: 

Idaho: Washington Water Power Co. 

Montana: Montana Power Co.

Washington: Crown Zellerbach Corporation; Puget Sound Power & Light Co.; 

Rayonier, Inc.; Washington Water Power Co., and Weyerhaeuser Timber Co.

DIVISION OP WORK

The stream gaging was done by the Water Resources Division of the Geological Survey, 

Carl G. Paulsen, chief hydraulic engineer, under the direction of Joseph V. B. Wells, 

chief of the Surface Water Branch. The data for stations in the several States were collected and prepared for publication under the supervision of the district engineers at 

the offices listed below. The records were reviewed and the manuscript prepared for publication under the direction of B. J. Peterson, chief, Annual Reports Section.

Information of a more detailed nature than that published for most of the gaging stations given in this report is on file in the district of1Ices listed above. Provisional 

records of discharge prior to publication, and other unpublished data concerning the 

gaging station records may usually be obtained from the district office.

DEFINITION OF TERMS AND ABBREVIATIONS

The terras of streamflow and other hydrologic data, as used in this report, are defined 

as follows:

Cubic foot per second (cfs) 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.

Cubic feet per second per square mile (cfsm) is the average niinber of cubic feet of 

water flowing per second from each square mile of area drained, assuming that the runoff 

is distributed uniformly in time and area.

Runoff In inches is the depth to which an area would be coverdd if all the water draining from it in a given period were uniformly distributed on its slurface. The term is used 

for comparing runoff with rainfall, which is also usually expressed in inches.

Acre-foot is the quantity of water require4 to cover an acre tjo the depth of 1 foot and 

is equivalent to 43,560 cubic feet. The termiis commonly used ir^ relation to storage for 

irrigation.

Cfs-day is the volume of water representediby a flow of 1 cubic foot per second for 

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

and represents a runoff of 0.0372 inch from 1 square mile.
EXPLANATION OF DATA 3

Stage-discharge relation is the relation between gage height and the amount of water 

flowing in a channel, expressed as volume per unit of time.

Control designates a feature downstream from the gage that determines the stage-discharge relation at the gage. This feature may be a natural constriction of the channel, 

a. long reach of the channel, or an artificial structure.

Contents is the volume of water In a reservoir. Unless otherwise Indicated, volume is 

computed on the basis of a level pool and does not include bank storage.

The drainage area of a stream at a specified location is that area, measured in a horizontal plane, which is so enclosed by a topographic divide that direct surface runoff from 

precipitation normally would drain by gravity into the river above the specified point. 

Figures of drainage area given herein include all closed basins, or noncontributing areas, 

within the area unless otherwise noted.

DOWNSTREAM ORDER OF LISTING GAGING STATIONS

Beginning with the series of reports for the water year ending September 30, 1951, the 

order of listing gaging-station records was changed. In this report, in a downstream direction along the main stem all stations on a tributary entering above a main-stem station 

are listed before that station. If a tributary enters between two main-stem stations, it 

is listed between them. A similar order is followed in listing stations on first rank, 

second rank, and other ranks of tributaries. To indicate the rank of any tributary on 

which a gaging station is situated and the stream to which it is immediately tributary, 

each indention in the listing of gaging stations in the table of contents of this report 

represents one rank. This downstream order and system of indention show which gaging stations are on tributaries between any two stations on a main stem and the rank of the tributary on which each gaging station is situated.

The order of listing used before the publication of the 1951 report listed first all 

stations on the main stem from headwaters toward mouth, then all stations on the uppermost 

tributary to the main stem from the tributary's source to mouth, and then all stations from 

source to mouth of the uppermost tributary to the tributary.

EXPLANATION OF DATA

The base data collected at gaging stations consist of records of stage and measurements 

of discharge. In addition, observations of factors affecting the stage-discharge relation, weather records, and other information are used to supplement base data 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 fluctuations. Measurements of discharge are made with a current meter by the general methods 

adopted by the Geological Survey on the basis of experience in stream gaging since 1888. 

These methods are described in Water-Supply Paper 888 and are also outlined in standard 

textbooks on the measurement of stream discharge. Typical structures in use at gaging 

stations are shown in figure 1.

Rating tables giving the discharge for any stage are prepared from stage-discharge relation curves defined by discharge measurements. If extensions to the rating curves are 

necessary to define the extremes of discharge, they are made on the basis of indirect

EXPLANATION OP DATA ' 5

measurements of peak discharge (such as slope-area or contracted-opening measurements, 

computation of flow over dams or weirs, and by other methods), velocity-area studies, and 

logarithmic plotting. Hie application of the daily mean gage height to those 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 daily 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. If the stage-discharge relation for a station is 

temporarily changed by the presence of aquatic growth or debris on the control, the daily 

mean discharge is computed by what is essentially the shifting-control method.

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

reservoirs, tributary streams, or other sources. This necessitates the use of the slope 

method in which the slope or fall in a reach of the stream is a factor in determining 

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 stagedischarge relation is affected by changing stage. If so, 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, and it becomes 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 other stations in the same or nearby basins. If the 

stage-discharge relation is affected by ice, this information is given in a note to the 

table. No mention is made of occasional days of ice effect if the degree of accuracy of 

daily records is not changed.

The data herein presented generally comprise a description of the station, a skeleton 

rating table, and a table showing the daily discharge and monthly and yearly discharge and 

runoff of the stream.

The description of the station gives the location, drainage area, records available, 

type and history of gages, average discharge, extremes of discharge, general remarks, ,,rid 

notations of revisions of the previously published record. The location of the gaging 

station and the drainage area are obtained from the most accurate maps available. River 

mileage, given under "Location" for some stations, is that determined and used by the Corps 

of Engineers unless otherwise noted. Under "Gage" are given the type of gage currently in 

use and the datum of the present gage above mean sea. level, and a condensed history of the 

types of gages, locations, and datums of previous gages for which discharge records are 

generally equivalent to those at the present site. Under "Average discharge" is given the 

average discharge for the number of years indicated. It is not given for stations having 

fewer than five complete years of record or for stations where changes in water development during the period of record cause the figure to have little significance. Under 

"Extremes" are given the maximum discharge and gage height; the minimum discharge if
6 SURFACE WATER SUPPLY, 1952, PART 12

there is little or no regulation; the minimum daily discharge if thtre 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, a crest-stage indicator, or a nonrecording gage read at the time of the crest. If the maximum gage height did not occur 

at the same time as the maximum discharge, it is given separately. Information pertaining 

to the accuracy of the records and conditions which affect the natural flow at the gaging 

station is given under "Remarks."

Previously published records of some stations have, been found to be in error on the 

basis of data or information later obtained. Revisions of such records are usually published along with the current records in one of the annual reports. In order to make it 

easier to find such revised records, a paragraph headed "Revisions (water years)" has been 

added to the description of all stations for which revised records have been published. 

Listed therein are all the reports in which revisions have been published, each followed 

by the water years for which figures are revised in that report. In listing the report 

number, "W" means water-supply paper. In listing the water years only one number is 

given; for instance, 1933 stands for the water year October 1, 1932, to September 30, 

1933. If no daily, monthly, or annual figures of discharge are concerned in the revision, 

that fact is brought out by notations after the year dates as follows: "(M)" means that 

only the instantaneous maximum discharge was revised; "(m)" that only the instantaneous 

minimum was revised; and "(P)" that only peak discharges were revised. If the drainage 

area has been revised, the report in which the revised figure was first published is given. 

It should be noted that for all stations for which cubic feet per second per square mile 

and runoff, in inches, are published, a revision of the drainage area necessitates corresponding revision of all figures based on the drainage area. Revised figures of cubic feet 

per second per square mile and runoff, in inches, resulting from a revision of the drainage 

area only are usually not published in the annual series of reports.

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

discharge for the greater part of the open-water period was determined by the shiftingcontrol method, the slope method, or other special methods involving an equivalent adjustment to the gage height of more than one-tenth foot.

Par stations equipped with water-stage recorders except those on streams subject to 

sudden or rapid fluctuation, the daily table gives the diocharge corresponding to the 

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

height may not indicate the true daily 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 daily mean discharge from a continuous gage-height graph and containing, as 

an essential element, a curve representing the stage-dischargs relation at the station. 

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

discharge corresponding to once-daily readings of the gage, or

readings, or to the mean gage height determined from gage-heijht graphs based on gage 

readings. For periods of rapidly changing stage, the daily msan discharge is determined

from gage-height graphs based on gage readings, the frequency

ACCURACY OF FIELD DATA AND COMPUTED RESULTS 7

In the table of daily discharge, the values for the maximum day and the minimum day for 

each month are underlined. If the value is repeated, it is underlined only on the first 

day of its occurrence.

In the monthly summary below the daily table, the line headed "Total" gives the sum of 

the daily values; it is the total cfs-days for the month. The line headed "Mean" gives 

the average flow in cubic feet per second during the month. Runoff for the month may be 

expressed in cubic feet per second per square mile (line headed "Cfsm"), or in inches (line 

headed "In."), or in acre-feet (line headed "Ac-ft"). Values for cubic feet per second per 

square mile and runoff, in inches, are omitted if the drainage area includes large noncfontributing areas, or if the average annual rainfall over the drainage basin is usually less 

than 20 inches.

In the yearly summary below the monthly summary, the values of maximum are the maximum 

daily discharges, not the momentary discharges when the water was at crest stage. Likewise, the minimums in this summary are the minimum daily discharges.

Peak discharges and the times of their occurrence and corresponding gage heights of 

most stations are listed below the table of daily and monthly discharge. All independent 

peaks above the selected base are given. The base discharge, which is given in parentheses, is selected so that an average of about three peaks a year will be presented. 

Peak discharges are not published for canals, ditches, drains, or for any stream for which 

the peaks are subject to substantial control by man.

Footnotes to the table of daily discharge indicate periods when discharge was computed 

or estimated by unusual or special methods during periods of no gage-height record and ice 

effect, or by other effects that reduce the degree of accuracy of the records. Days on 

which discharge measurements were made are indicated by asterisk and footnote unless they 

were made at frequent regular intervals, in which instance the general frequency of discharge measurements is given under "Remarks" in the station description.

For most gaging stations 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 daily contents or stage is given, A skeleton table of capacity at given 

stages is usually given in the first report in which data for the reservoir are published, 

but it is omitted from succeeding reports.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of streamflow data depends primarily on (1) the stability 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 discharge, and interpretation of records.

The station description states the degree of accuracy of the records. "Excellent" indicates that, in general, the error in the daily records is believed to be less than 5 percent; "good," less than 10 percent; "fair," less than 15 percent; and "poor," probably 

more than 15 percent, ^he records of monthly and yearly mean discharge and runoff are, 

in general, more nearly accurate than the daily records.

Runoff at some stations, as indicated by the monthly mean, may vary widely from natural 

runoff, owing to diversion, consumption, regulation by storage, increase or decrease in

303190 O - 54 - 2
8 SURFACE WATER SUPPLY, 1952, PART 12

evaporation due to artificial causes, or to other factors. For such stations, values of 

cubic feet per second per square mile and runoff, in inches, are not published unless 

storage or diversion records are included to indicate 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. Evaporation from a reservoir is 

not included in the adjustments for changes in reservoir contents, unless it is so stated. 

Even at those stations where adjustments are made, large errors in computed runoff may 

occur when relatively large negative adjustments are made or when evaporation is large in 

comparison with the observed discharge.

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 actually show the water supply available at the stations for further development, 

because water must first be supplied to existing irrigation systems.

PUBLICATIONS

To facilitate publication of the annual series of reports, the area of the United 

States is divided into 14 parts whose boundaries coincide with certain natural drainage 

lines. Formerly, the results of streamflow measurements were published in 14 volumes, one

The records at most of the stations discussed in these reports extend over many 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 are listed in the same order as the 

streams and gaging stations in the body of the report. An index of the records obtained 

before 1904 has been published in Water-Supply Paper 119.

Each of the reports on the surface-water supply for the year 1939 (Water-Supply Paper

SKAGIT RIVER BASIN 

Skagit River at Newhalem, Wash.

145

Location. Lat 48°40', long. 121°15', in SE^ sec. 21, T. 37 N., R. 12 E. , on right bank at 

powerplant 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.

Drainage area. 1,160 sq mi, approximately, of which 390 sq mi is in Canada.

Records available. December 1908 to May 1914 and October 1920 to September 1951 in reports 

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

Water-Supply Bulletin 5.

.Gage. Water-stage recorder. Datum of gage is 400 ft above mean sea level, unadjusted. 

Prior to May 24, 1914, staff gage at site a quarter of a mile upstream at different 

datum. Nov. 15, 1920, to June 4, 1923, staff gage at site 500 ft upstream at same datum.

Average discharge. 44 years, 4,328 cfs (adjusted for storage in Diablo Reservoir since 

October 1929 and Ross Reservoir since March 1940).

Extremes. Maximum discharge during year, 12,000 cfs Oct. 29 (gage height, 86.64 ft), but 

may have been higher sometime during period of no gage-height record in October; minimum, 216 cfs Dec. 2 (gage height, 78.96 ft); minimum daily, 702 cfs Dec. 2.

1908-14, 1920-52: Maximum discharge, 63,500 cfs Nov. 29, 1909 (gage height. 22.0 

ft, from floodmark, site and datum then in use); minimum, 54 cfs Nov. 1, 1943 (gage 

height, 78.15 ft); minimum daily, 136 cfs Aug. 24, 1930.

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

good. Water is diverted 3 miles above station and is returned to river at Seattle powerplant just above station. Flow regulated by Diablo and Ross Reservoirs (see pp. 155,142) 

having a combined capacity of 1,279,000 acre-ft.

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

bank on upstream side of highway bridge at Bonners Perry.

drainage area.--13 ,000 sq mi, approximately.

Records available.--May to October 1904, October 1927 to September 1952 (gage heights only

 prior to April 1928). Sage-height records collected in this vicinity since 1904 are 

contained in reports of United States Weather Bureau.

Gage.--Wire-weight gage read once daily. Water-stage recorder 800 ft across channel from 

wire-weight gage at same datum used as supplementary gage during high stages. Datum of 

gage is 1,743.00 ft above mean sea level with respect to Geological Survey benchmark 

V-3-1929 at elevation 1,777.08 ft. Gage readings have been reduced to elevations above 

mean sea level. Datum of 1929, supplementary adjustment of 1947, is 0.02 ft higher. 

May 1 to Oct. 15, 1904, staff gage on railroad bridge three-quarters of a mile downstream at different datum. Oct. 1, 1927, to Nov. 30, 1929, staff gage near left bank. 

Dec. 1, 1929, to June 12, 1933, chain or wire-weight gages on old highway bridge 40 ft 

downstream. Datum of gages Oct. 1, 1927, to Jan. 2, 1931, was about 0.23 ft lower.

Average discharge.--24 years (1928-52), 14,230 cfs.

Extremes.--Maximum daily discharge during year, 69,700 cfs Apr. 29; maximum elevation,

 1,769.30 ft Apr. 29; minimum daily discharge, 4,050 cfs Dec. 24; minimum elevation, 

1,743.14 ft Mar. 24.

1927-52: Maximum discharge, 139,000 cfs May 27, 1948 (affected by dike breakage 

downstream); maximum elevation, 1,778.32 ft May 28, 1948; minimum daily discharge, 1,300 

cfs Feb. 8, 1936; minimum elevation, 1,741.14 ft datum then in use, Dec. 5, 1929, Dec. 

29, 1930.

Flood of June 1894 reached a stage of 1,777.2 ft, present datum.

Remarks. Records excellent except those for periods of ice effect, which are good. Backwater from Kootenay Lake usually present at Bonners Ferry. Discharge for periods of 

backwater at Boom Camp from Kootenay Lake, Apr. 26 to May 6, May 12 to July 5, computed 

on basis of fall between gages at Boom Camp and near Bonners Ferry; that for remainder 

of year on basis of stage-discharge relation for station at Boom Camp. Discharge measurements made at station near Bonners Ferry. Dikes of all drainage districts in 

Kootenai Valley in United States and Canada held during year. No diversion or regulation 

above Station.

elevation, 1,738.52 ft Apr. 2, 3, 1944.

Remarks. Records excellent except those for periods of ice effect, which are good. 

Dikes of all drainage districts in Kootenai Valley in United States and Canada held 

during year. Discharge computed from fall-mean stage-discharge relations determined 

on basis of fall in reach between stations at Klockmann Ranch and at Porthill and discharge measurements made at station near Copeland. 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.

KOOTENAI RIVER BASIN 187

Kootenai River at Porthill, Idaho 

(International gaging station)

Location. Lat 49°00 I 00", long. 116 030'10", in SWj- sec. 8, T. 65 N. , R. 1 W. , on right 

bank: 300 ft south of international boundary at Porthill.

Drainage area. 13,700 sq mi, approximately.

Records available. May to July 1904 and October 1327 to March 1928 (gage heights only) 

and April 1928 to September 1952 in reports of Geological Survey. October 1924 to 

September 1927 (gage heights only) in reports of Department of Resources and Development , Canada .

Gage . Water-stage recorder. Datum of gage is 1,700.00 ft above mean sea level referred 

Fo benchmark 10-M-1928, at elevation, 1,767.68 ft. Gage readings have been redu-.ed to 

elevations above mean sea level. Datum of 1929, supplementary adjustment of 1947, and 

datum of Geodetic Survey of .Canada, Pub. 24, 1951 edition, are 0.03 ft higher. Prior 

to May 17, 1928, staff gages at approximately same site. Datum of gages prior to 

July 28, 1928, was 38.34 ft higher, except in 1904 when different datum was used.

Average discharge. 24 years, 15,105 cfs.

Extremes. Maximum daily discharge during year, 71,200 cfs Apr. 29; maximum elevation, 

1,758.86 ft May 22; minimum daily discharge, 4,570 cfs Dec. 24; minimum elevation, 

1,740.30 ft Apr. 5.

1928-52: Maximum daily discharge, 125,000 cfs June 1, 1948; maximum elevation, 

1,766.16 ft May 31, 1948; minimum daily discharge, 1,380 cfs Feb. 8, 1936; minimum 

elevation, 1,738.21 ft Apr. 3, 1944.

Maximum elevation known, 1,772.7 ft in June 1894, present datum.

Remarks . Records excellent except those for periods of ice effect near Copeland, which 

are good. Daily discharge represents entire flow passing international boundary, computed by adding tributary inflow, including that of Boundary Creek, to flow at station 

near Copeland and correcting for storage change in channel and flooded areas between 

stations near Copeland and at Porthill. Boundary dike of Reclamation Farm and United 

States Forest Service roadway dike (south side 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. Dikes of all 

drainage districts in Kootenai Valley in United States and Canada held during the year.

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

United States under agreement with Canada.

256 PEND OREILLE RIVER BASIN

Pend Oreille River below Z Canyon, near Metaline Falls, Wash. 

(International gaging station)

Location. Lat 48°58'50", long. 117°20'40", in lot 2, sec. 11, T. 40 N., R. 43 E., on right 

bank three-quarters of a mile downstream from 1 Canyon, \\ miles south of international 

boundary, 5 miles downstream from Slate Creek, and 10 miles downstream from town of 

Metaline Falls.

Drainage area. 25,200 sqmi, approximately.

Records available.--November 1908 to September 1910 (gage heights only), October 1912 to 

September 1952. Published as Clark Fork at Metaline Falls prior to October 1928 and 

as Clark Fork below Z Canyon, near Metaline Falls October 1928 to September 1937.

Gage. Water-stage recorder. Datum of gage is 1,721.80 ft above mean sea level, datum of 

T929 (levels by Corps of Engineers). Prior to Dec. 19, 1928, staff gages at Metaline 

Falls about 10 miles upstream at datum approximately 262.2 ft higher.

Average discharge.--40 years (1912-52), 26,200 cfs.

Extremes. Maximum discharge during year, 91,600 cfs May 25 (gage height, 38.44 ft); minimum, 4,960 cfs Sept. 5 (gage height, 9.73 ft).

1912-52: Maximum discharge, 171,300 cfs June 13, 1948 (gage height, 60.25 ft); minimum, 2,500 cfs Dec. 12, 1919 (gage height, -2.4 ft, site and datum then in use).

Remarks. Records good except those for periods of doubtful or no gage-height record, which 

are fair. Water diverted above station for many uses, but principally for irrigation. 

In 1946 there were diversions for irrigation of about 339,300 acres, and there probably 

has not been any appreciable change since that time. Flow affected by natural storage 

in Pend Oreille Lake (see p. 251 T, some regulation by Flathead Lake (see p. 238 ), 

Hungry Horse and by smaller reservoirs in Pend Oreille River basin in Montana (see p. 257).

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

States under agreement with Canada.

Revisions (water years). W 442: 1913.

258 COLUMBIA RIVER MAIN STEM

Columbia River at international boundary 

(International gaging station)

Location. Lat 49°00'03", long. 117°37'40" ( in SE£ sec. 4, T, 40 N,, R, 41 E., on left

 bank at international boundary, half a mile downstream from Pend Oreille River,

Drainage area. 59,700 sq mi, approximately. 

Records available.--March 1938 to September 1952.

Gage.--Water-stage recorder. 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. Since May 31, 

1942, auxiliary water-stage recorder 2.2 miles downstream from base gage. Auxiliary 

staff gage Jan. 1 to May 30, 1942, at same site.

Average discharge. 14 years, 93,630 cfs.

Extremes."Maximum discharge during year, 300,200 cfs May 29 (elevation, 1,321.66 ft);

 minimum, 33,800 cfs Jan. 1 (elevation, 1,292.91 ft).

1938-52: Maximum discharge, 550,100 cfs June 12, 1948 (elevation, 1,338.13 ft); 

minimum, 20,700 cfs Mar. 9, 1944 (elevation, 1,289.91 ft).

Plow of about 12,900 cfs occurred Jan. 30 or 31, 1937, based on information from 

other gaging stations (elevation, 1,287.9 ft), from rating curve extended below 1,291.6 

ft); may have been as low sometime in January 1930.

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

 are~fair. Many diversions above station for irrigation. It was estimated that 346,700 

acres were under irrigation in the United States in 1946. Water is diverted for 

irrigation of an additional 25,000 acres in Canada. The flow is affected by internationally controlled storage in Kootenay Lake as well as by natural and controlled 

regulation in lakes and reservoirs in Pend Oreille River basin. Records of chemical 

analyses and water temperatures for the water year 1952 are given in Water-Supply Paper 

1253.

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

united states under agreement with Canada.

292 COLUMBIA RIVER MAIN STEM

Columbia River at Grand Coulee Dam, Wash.

Location.--Lat 47°58'00", long. 118°58'45", opposite lot 4, sec. 36, T. 29 N., R. 30 E.,

 Iri pier 3 of highway bridge, 2,500 ft downstream from Grand Coulee Dam and 14 miles 

upstream from Nespelem River.

Drainage area. 74,100 sq mi, approximately.

Records available. April 1913 to September 1952 (monthly discharge only, April 1913 to 

June 1923, January 1924 to May 1928).

se.--Water-stage recorder. Datum of gage is at mean sea level, Bureau of Reclamation 

adjustment of 1937. June 27 to Dec. 31, 1923, June 12, 1928, to Mar. 31, 1931, staff 

gages at site half a mile upstream at datum 2.4 ft lower. Apr. 1, 1931, to Dec. 31, 

1935, water-stage recorder on right bank at site 850 ft downstream at present datum.

Average discharge.--39 years, 107,800 cfs (adjusted for diversion by pumping from Franklin

 D. Roosevelt Lake since May 1951, and change in contents in Franklin D. Roosevelt Lake

since October 1939). . Extremes. Maximum discharge during year, 354,700 cfs May 25 (elevation, 972.12 ft); min-

 Imum, 28,800 cfs Dec. 17 (elevation, 935.47 ft).

1913-52: Maximum discharge, 637,800 cfs June 12. 1948 (elevation, 987.90 ft); minimum, may have been less than 15,300 cfs (estimated] in January or February 1937, 

when stage-discharge relation was affected by ice.

Maximum discharge known, 725,000 cfs (estimated) during flood of June 1894. 

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

 good. Diversion by pumping from Franklin D. Roosevelt Lake for Columbia Basin project. 

Other diversions above station for irrigation are small percentage of flow past gage. 

Flow regulated by Franklin D. Roosevelt Lake (see preceding page) and reservoirs in 

Kootenai, Pend Oreille, and Spokane River basins. Records of chemical analyses and 

water temperatures for the water year 1952 are given in Water-Supply Paper 1253.

Discharge, In cubic feet per second, water year October 1951 to September 1952

298 METHOW ROTER BASIN

Methow River at Twisp, Wash.

Location.--Lat 48°21'40", long. 120°06'50", in NW£ sec. IV, T. 33 N., R. 22 E., on left 

 bank a quarter of a mile downstream from Twisp River and 0.3 mile east of center of 

Twisp.

Drainage area.--1,330 sq mi, approximately.

Records available. June 1919 to September 1929, October 1933 to September 1952.

Gage.--Water-stage recorder. Altitude of gage is 1,580 ft (from topographic map). Prior

o Oct. 3, 1919, several staff gages in the immediate vicinity at different datum. 

Oct. 3, 1919, to Nov. 6, 1933, chain gage at site 40 ft upstream at same datum as staff 

Nov. 7 to Dec. 18, 1933, staff gage at present site at different datum.

Average discharge. 29 years, 1,281 cfs.

Extremes.--Maximum discharge during year, 10,000 cfs May 19 (gage height, 6.50 ft); minimum, 210 cfs Sept. 20; minimum gage height, 1.97 ft Feb. 18.

1919-29, 1933-52: Maximum discharge, 40,800 cfs May 29, 1948 (gage height, 12.94 

ft), from rating curve extended above 18,000 cfs on basis of slope-area determination 

of peak flow; minimum observed, 134 cfs Sept. 4, 5, 1926, Sept. 9, 10, 1929, but may 

have been less during period of ice effect Jan. 6 to Mar. 4, 1937.

Remarks. Records good except those for periods of ice effect or no gage-height Record, 

or indefinite stage-discharge relation, which are poor. A large part of the flow 

diverted above station for irrigation by two canals of Methow Valley Irrigation District, by Risley ditch, and by many other smaller ditches. It is estimated 7,410 

acres were irrigated in 1946 by water diverted above this station.

Revisions. W 512: Drainage area.

Average discharge.--26 years (1911-12, 1927-52), 196 cfs.

Extremes. Maximum discharge during year, 1,160 cfs June 5 (gage height, 4.15 ft); minimum not determined, probably occurred sometime during period of ice effect in February.

1910-13, 1927-52: Maximum discharge, 3,900 cfs May 28, 1948 (gage height, 8.1 ft, 

from floodmarks), from rating curve extended above 1,300 cfs on basis of slope-area and 

contracted-opening determinations of peak flow; minimum, less than 9.4 cfs during 

period of ice effect Jan. 15-25, 1930.

Remarks. Records fair except those for periods of ice effect or no gage-height record, 

or periods of shifting control, which are poor. No diversion or regulation.

Cooperation. Qage-height record collected in cooperation with, and four discharge measurements furnished by Washington Water Power Co.

eans based on records, for stations at Stehskln
302 CHELAN RIVER BASIN 

Chelan River at Chelan, Wash.

Location. Lat 47°50'05", long. 120°00'40", in SE£ sec. 13, T. 27 N., R. 22 E. , in forebay 

upstream from control dam at Chelan.

Drainage area. 951 sq mi.

Records available. October 1903 to September 1952.

Gage. Water-stage recorder. Datum of gage is at mean sea level, adjustment of 1912. 

Prior to Jan. 7, 1927, staff gage at site 800 ft downstream at same datum. Jan. 7 to 

Sept. 30, 1927, staff gage about 500 to 1,000 ft below dam at same datura. Oct. 1, 

1927, to Nov. 10, 1928, staff gage and Nov. 11, 1928, to Mar. 20, 1939, water-stage 

recorder, at sites 2-| miles downstream at same datum.

Average discharge. 49 years, 2,023 cfs (adjusted for storage).

Extremes. Maximum daily discharge during year, 7,490 cfs Jan. 6; minimum daily, 154 cfs

1903-52: Maximum daily discharge, 16,000 cfs May 30, 1948; no flow part of day 

Jan. 30, 1917, when lake outlet was blocked with ice, and at other times owing to artificial regulation.

Remarks. Unmeasured water that is diverted for irrigation above station is small percentage of total runoff. Washington Water Power Co. diverts water at Chelan to develop an 

average of about 54,000 horsepower and to irrigate an unknown area near Chelan which 

quantity is included in records of daily discharge. An estimated 6,280 acres were 

irrigated from the Chelan River basin in 1946, resulting in an estimated depletion of 

11,000 acre-ft. Plow regulated by Lake Chelan (see preceding page).

Cooperation. Records of water used for power and irrigation furnished by Washington Water 

Power.Co.

Revisions (water years). W 482: 1904-13. W 612: 1924. W 1215: Drainage area.

Revised figures of discharge for March and April 1951; superseding those published 

in Water-Supply Paper 1216, are given herewith.

Records available. October 1910 to September 1925, June 1951 to September 1952.

Gage. Water-stage recorder. Altitude of gage is 690 ft (from topographic map). October 

1910 to Sept. 30, 1925, staff gage at site three-quarters of a mile upstream at different datum.

Average discharge. 16 years (1910-25, 1951-52), 487 cfs (unadjusted).

Extremes. Maximum discharge during year, 2,360 cfs May 19 (gage height, 4.45 ft); minimum not determined, occurred during period of no gage-height record.

1910-25, 1951-52: Maximum discharge observed, 5,150 cfs June 17, 1916 (gage height, 

5.0 ft, site and datum then in use); minimum observed, 32 cfs Jan. 30, 1923 (discharge 

measurement), but may have been less during period of ice effect.

Remarks. Records good except those for periods of ice effect or no gage-height record, 

which are fair. Many diversions above station for irrigation of an estimated 2,560 

acres in 1946 with a resulting estimated depletion of 4,480 acre-ft of flow. Occasional regulation by millpond 10 miles upstream.

water-stage recorder at site 0.4 mile downstream at different datum.

Extremes. Maximum daily discharge during year, 23 cfs Jan. 21 to Feb. 1; no flow Feb. 2-20.

T9~09-12, 1942-52: Maximum discharge, 3,000 cfs Feb. 7, 1943 (gage height, 4.25 ft, 

datum then in use), from rating curve extended above 20 cfs on basis of slope-area measurement of flood in Lind Coulee; no flow for short intervals in June and July 1948, and 

part of each day Feb. 2-21, 1952, when water was shut off at O'Sullivan Dam.

Remarks. Records fair. Many small diversions for irrigation, Plow regulated by O'Sullivan Dam and Moses Lake.

326 YAKIMA RIVER BASIN

Yakima River near Martin, Wash.

Location.--Lat 47°19'10", long. 121°20'10", in NE£ sec. 12, T. 21 H., R. 11 E., on left 

bank 800 ft downstream from dam at outlet of Keechelus Lake, 3| miles northwest of 

Martin, and 12 miles upstream from Easton.

Drainage area. 55.8 sq mi.

Records available. October 1903 to September 1952.

Ga^e. Water-stage recorder and masonry channel. Datum of gage is 2,422.40 ft above mean

sea level ( Bureau of Reclamation benchmark). Prior to July 20, 1923, staff gages at 

 several sites within 2 miles of present site at various daturns.

Average discharge.--48 years (1904-52), 327 cfs (adjusted for storage since January 1906).

Extremes. Maximum discharge during year, 789 cfs July 18, 19 (gage height, 7.03 ft); minitnum, 2.0 cfs Oct. 28 (gage height, 2.14 ft).

1903-52: Maximum discharge, 7,370 cfs Mar. 26, 1915, when temproary crib dam was 

washed out; practically no flow when gates in Keechelus Lake Dam are closed.

Remarks Records good except those below 10 cfs, which are fair. Plow regulated by 

Keechelus Lake (see p. 342 ). Keechelus Lake spillway discharge, computed from reservoir elevations and spillway rating, bypasses gage and is added to flow at station. No 

spill occurred during year.

Cooperation. Gage-height record collected in cooperation with, and six discharge measurements furnished by Bureau of Reclamation.

Records available. October 1903 to September 1952.

Gage. Water-stage recorder. Datum of gage is 2,188.10 ft above mean sea level (Bureau 

of Reclamation benchmark). Prior to July 22, 1913, staff gage and July 22, 1913, to 

Aug. 14, 1916, water-stage recorder, at site a quarter of a mile upstream at different 

datum. Aug. 15, 1916, to Oct. 8, 1927, water-stage recorder at site half a mile downstream at different datum. Oct. 9, 1927, to Sept. 30, 1951, water-stage recorder at 

present site at datum 1.33 ft higher.

Average discharge. 49 years, 284 cfs (adjusted for storage since October 1905).

Extremes. Maximum discharge during year, 1,560 cfs June 16 (gage height, 7.13 ft); minimum not determined, probably occurred sometime during period of no gage-height record. 

1903-52: Maximum discharge, 2,530 cfs May 28, 1948 (gage height, 8.45 ft, present 

datum); no flow at times when gates in dam are closed.

Remarks. Records good except those below 20 cfs, which are fair, and those for periods 

of no gage-height record or ice effect, which are poor. No diversion. Flow regulated 

by Kachess Lake (see p. 342).

Cooperation. Gage-height record collected in cooperation with, and nine discharge measurements furnished by Bureau of Reclamation.

Revisions (water years). W 369: 1904, 1907-8. W 1216: Drainage area.

* Discharge measurement made on this day. 

t Change in contents in Cle Elum Lake, in acre-feet. 

Note.--Doubtful gage-height record Kov. 14 to Dec. 7; discharge estimated on basis of 1 discharge 

measurement and weather records.
YAKIMA RIVER BASIN 329

Yakima River at Cle Elurn, Wash.

Location. Lat 47°11'20", long. 120°56'40", in sec. 27, T. 20 N., R. 15 E., on left bank 

at highway bridge at Cle Elum just upstream from Roslyn Creek, 7 miles upstream from 

Teanaway River.

Drainage area.--500 sq mi, approximately.

Records available.--August 1906 to September 1952.

Gage.--Water-stage recorder. Datum of gage is 1,902.27 ft above mean sea level, subject 

fo adjustment to datum of 1929. Prior.to Aug. 12, 1910, chain gage on highway bridge 

at different datum. Aug. 12, 1910, to July 11, 1911, staff gage 30 ft below bridge at 

present datum. July 12, 1911, to June 27, 1923, water-stage recorder under highway 

bridge at present datum. June 28, 1923, to Oct. 21, 1924, staff gages at various locations near bridge at present datum.

Average discharge. 46 years, 1,958 cfs (adjusted for storage since October 1906 and* 

Kittitas Canal diversion since 1930).

Extremes.--Maximum discharge during year, 3,520 cfs June 6 (gage height, 8.43 ft); minimum, 170 cfs Nov. 4 (gage height', 5.19 ft).

1906-52: Maximum discharge, 25,600 cfs Nov. 14, 1906 (gage height, 12.5 ft, from 

floodmarks); minimum, 64 cfs Nov. 16, 17, 1929, Dec. 4, 1936.

Remarks. Records good except those for periods of doubtful or no gage-height record or 

ice effect, which are fair. Kittitas high-line canal diverts water from river at 

Easton for irrigation below station. Several smaller diversions for irrigation of 

several hundred acres above station. Considerable regulation by Keechelus, Kachess, 

and Cle Elum Lakes (see p. 342 ).

Cooperation. Gage-height record collected in cooperation with, and nine discharge measureinents furnished by Bureau of Reclamation.

Revisions (water years). W 369: 1910-11. W832: 1936.

Extremes. --Maximum discharge during year, 4,130 cfs May 20 (gage height, 14.21 ft); minimum, 54 cfs Nov. 24, 25 (gage height, 10.15 ft).

1905, 1908-12, 1915-52: Maximum discharge, 32,200 cfs Dec. 22, 23, 1933 (gage height, 

14.33 ft, site and datum then in use); minimum, 1 cfs Nov. 7, 1942, and for many days 

during winter of 1943-44, result of regulation and diversion.

Remarks . --Records good except those for periods of ice effect or no gage-height record, 

which are poor. Plow regulated by Bumping Lake and Tieton Reservoir (see p. 342), by 

diversion at Oak Plat for municipal supply of city of Yakima below station, and by diversion of Selah Valley, Tieton, and Wapatox Canals. Small unmeasured diversions for 

irrigation of approximately 420 acres above station.

Cooperation. --Gage-height record collected in cooperation with, and six discharge measurements furnished by Bureau of Reclamation.

Location. Lat 46°29'40", long. 120°26'10", in sec. 28, T. 12 N., R. 19 E., on left bank 

Just downstream from Sunnyside diversion dam, ij miles east of Parker, and 3 miles 

downstream from Ahtanum Creek.

Drainage area. 3,650 sq. mi, approximately.

Records available. April 1908 to September 1952 (October 1921 to September 1931, monthly 

discharge only published in Water-Supply Paper 870). Prior to October 1916, published 

as "near Wapato."

Gage. Water-stage recorder. Datum of gage is 886.05 ft above mean sea level (Bureau of 

Reclamation benchmark). Apr. 25, 1908, to Feb. 17, 1909, hook gage at site 25 ft above 

headgate of Sunnyside Canal, with datum same as the elevation of crest of diversion dam. 

Feb. 18, 1909, to Oct. 23, 1914, chain gage and Oct. 24, 1914, to Aug. 16, 1915, staff 

gage, at present site at datum 2.00 ft higher than present datum Feb. 18, 1909, to 

Dec. 31, 1913, and at present datum thereafter.

Extremes. Maximum discharge during year, 6,570 cfs Aug. 10 (gage height, 6.70 ft); minimum, 36 cfs May 3 (gage height, 1.36 ft).

1908-21, 1931-52: Maximum discharge, 65,000 cfs Dec. 23, 1933 (gage height, 15.0 

ft, from high-water marks); practically no flow for several days during latter part of 

irrigation season in most years as result of diversions.

Remarks. Records good except those below 100 cfs, which are fair.- Diversions above station for irrigation of large area. During the irrigation season when Sunnyside Canal 

is carrying water, as much as 18 cfs, depending upon the stage of the canal, is released ahead of the fish screens and passes the river and canal gaging stations unmeasured. Some regulation by diversions and by Keechelus, Kachess, Cle Elum, and 

Bumping Lakes, and Tieton Reservoir (see p.342 ) 

Cooperation. Records collected and prepared in cooperation with Bureau of Reclamation 

ana Office of Indian Affairs.
