SCOPE OF WORK

This volume is one of a series of 20 reports presenting records of stage, discharge, and 

content of streams, lakes, and reservoirs in the United States during the 1959 water year. 

Since 1888, when the United States Geological Survey first studied streamflow in relation 

to problems of irrigation, similar records have teen obtained at more than 15,200 gaging 

stations in the 50 States. On September 30, 1959, the Geological Survey and cooperating 

organizations were maintaining 7,110 gaging stations. Partial-record stations for low flow 

or for flood flow have been operated at many other points. In addition, discharge measurements are made at miscellaneous sites. The records for the 1959 water year at gaging 

stations, partial-record stations, and miscellaneous sites in the Pacific slope basins in 

Washington and Upper Columbia River basin are given in this report.

DIVISION OF WORK

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

under the direction of personnel shown in the preface. The data for stations in the several States were collected and prepared for publication in the district offices listed 

below .

State District office Address

914 Jefferson Street. 

409 Federal Building. 

207 Federal Building.

a/ Including Fend Oreille River at Newport, Wash, 

b/ Except Pend Qrellle River at Newport.

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 offices listed above. Provisional 

records of discharge prior to publication, and other unpublished data concerning the 

gaging-station records may generally be obtained from the district office.

DEFINITION OF TERMS AND ABBREVIATIONS

The terms of streamflow and other hydrologic data, as used In this report, are defined 

as follows:

Gaging station is a particular site on a stream, canal, lake, or reservoir where systematic observations of gage height or discharge are obtained. When used in connection 

with a discharge record, the term is applied herein only to those gaging stations where a 

continuous record of discharge is obtained.

Partial-record station is a particular site where limited streamflow data are collected 

systematically over a period of years for use in hydrologic analyses.

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 number 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 (in.) shows the depth to which the drainage area would be covered if 

all the runoff for a given time period were uniformly distributed on it.

Acre-foot (ac-ft) is the quantity of water required to cover an acre to the depth of 

1 foot and is equivalent to 43,560 cubic feet.
DOWNSTREAM ORDER AND STATION NUMBERS 3

Cfs-day is the volume of water represented by 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.

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 stagedischarge 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 noneontribut ing areas, 

within the area unless otherwise noted.

WSP is used as an abbreviation for "Water-Supply Paper" in references to previously 

published reports.

DOWNSTREAM ORDER AND STATION NUMBERS

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 downstr?am 

direction along the main stem; all stations on a tributary entering above a main-st'3m 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.

As an added means of identification, each gaging station and partial-record station has 

been assigned a station number. The numbers have been assigned in the same downstream 

order used in this report. In assigning station numbers, no distinction is made between 

partial-record stations and regular gaging stations, so that the station number for a partial-record station indicates downstream-order position in a list made up of both types of 

stations. Gaps are left in the numbers to allow for new stations that may be established; 

hence the numbers are not consecutive. The complete number for each station includes the 

part number, but the station number shown in this report, just to the left of the station 

name, consists of only the essential digits of the complete number. For example, for a
4 SURFACE WATER SUPPLY, 1959, PART 12

station with the complete number 12-0115.00, the station number shown in this report is 

115. The notation to the left of the hyphen is the part number; it is 12 for all stations 

in this report and is therefore omitted.

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.

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 tasis of indirect 

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. The 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 pbtained 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 orange in stage is 

used as a factor in the determination of discharge.

At most gaging stations in the northern part of the United States anc1 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.
EXPLANATION OF DATA 5

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 of 

the stream. Records are published for the water year which begins on October 1 and ends 

on September 30. A calendar for the water year 1959 Is shown on page IV for the purpose 

of finding the day of the week for any date.

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

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

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 "Records available" are given the periods for which there are published records generally equivalent to those of the present 

site. 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 used during the period of records available. 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 there is little or no regulation; the minimum daily discharge if there 

is extensive regulation (also the minimum discharge if useful); and the minimum gege 

height (unless it is of no importance). In the first paragraph, the data given are for 

the complete current water year unless otherwise specified. In the second paragraph, the 

data given are for the periods of record within the calendar year dates in the heading 

(not necessarily those for the complete years indicated by the heading dates). Reliable 

information concerning major floods that have occurred outside the period of record are 

given in the third or last paragraph under "Extremes." 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 water 

years only one number is given; for instance, 1933 stands for the water year Octobar 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 f.'.gure
6 SURFACE WATER SUPPLY, 1959, PART 12

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. Skeleton rating tables are generally 

not published for stations on canals.

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

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

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-discharge relation at the station. For 

stations equipped with nonrecording gages, the table of daily discharge gives the discharge 

corresponding to once-daily readings of the gage, or to the mean of twice-daily readings, 

or to the mean gage height determined from gage-height graphs based on gage readings. For 

periods of rapidly changing stage, the daily mean discharge is determined from gage-height 

graphs based on gage readings, the frequency of which is stated in the station description.

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

each month are underlined. If the figure 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 figures; it is the total cfs-days for the month. The line heacfed "Mean" gives 

the average flow in cubic feet per second during the month. Discharge fop? 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"). Figures for cubic feet per 

second per square mile and runoff in inches are omitted if the drainage srea includes 

large noneontributing 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 figures 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.
ACCURACY OF FIELD DATA AND COMPUTED RESULTS 7

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 "Remarka" 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 published each year for all reservoirs for which records are published on a daily 

basis, but is not published for reservoirs for which only monthly data are given.

At many gaging stations water samples are collected from the streams for the purpose of 

making chemical analyses, computing dissolved solids, suspended sediment loads, and particle-size distribution, or measuring water temperatures. For most of these samples the 

results are published in an annual series of water-supply papers entitled "Quality of Surface Waters of the United States" which is issued in four volumes. In this report under 

"Remarks" a reference is made to quality-of-water records collected at gaging stations on 

a regular basis and published in the quality-of-water reports. At many other gaging stations quality-of-water data are obtained at irregular intervals and published ss "miscellaneous analyses" in <juality-of-water reports; such records are not referred to in "Remarks" 

paragraph in this report. At many gaging stations water temperature is obtained also at 

the time a discharge measurement is made; such temperature readings are not reported in 

the quality-of-water annual reports.

Data collected at partial-record stations and at miscellaneous sites are given at the 

end of each report. Partial-record stations are presented in two tables. The first is a 

table of discharge measurements at low-flow partial-record stations, and the second is a 

table of annual maximum stage and discharge at crest-stage stations. Discharge measurements at miscellaneous sites are given in a third table. Occasionally, a series of discharge measurements are made within a short time period to investigate the seepage gains 

or losses along a reach of a stream or to determine the low-flow characteristics of an 

area. Such measurements are given in special tables after the list of measurements at 

miscellaneous sites.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream flow 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. The records of monthly and yearly mean discharge and runoff 

are, in general, more nearly accurate than the daily records.
8 SURFACE WATER SUPPLY, 1959, PART 12

Discharge 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 evaporation due to artificial causes, or to other factors. For such stations, figures 

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

satisfactory adjustments can be made for diversions, 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

Basic data for gaging stations are published in an annual series of reports consisting 

of 20 volumes, including one each for the States of Alaska and Hawaii. The area of the 

other 48 States is divided into 14 parts whose boundaries coincide with certain natural 

drainage lines. Formerly, the annual series of reports on surface-water supply consisted 

of 14 volumes, one for each of the 14 parts. Beginning with the reports fo" 1951, the 

records for the 48 States were published in 18 volumes, there being 2 volumes each for 

Parts 1, 2, 3, and 6. The boundaries of the various parts are indicated by the following

A compilation of records for the area covered by this report through September 1950 

has been published as Water-supply Paper 1316. That report contains a summary of monthly 

and annual discharges for all previously published records as well as some records not 

contained in the annual series of water-supply papers. All records were reexamined and 

revised where warranted. Estimates of discharge were made to fill short gaps whenever 

practical.
HYDROLOGIC CONDITIONS 11

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 t?-ese special reports also contain other pertinent hydrologic information and analyses and compilations of data relating to earlier notable floods. The following is a list of there reports:

RECORDS OF DISCHARGE COLLECTED BY AGENCIES OTHER THAN THE GEOLOGICAL SURVEY

The table below contains a list of gaging stations for the area covered by this report, 

at which records of discharge were collected during the water year October 1958 to September 1959 by agencies other than the Geological Survey. The records of these stations 

are not contained in publications of the Geological Survey.

Note. Records of daily discharge for many streams, canals, and drains in Washington and Montana 

for 1959 and earlier years have been collected by the Bureau of Reclamation and the Bureau of Indian 

Affairs of the United states Department of the Interior in connection with Irrigation and drainage 

projects. These records have not been published. The Inter-Rocky Mountain Forest and Range Experiment Station collects records of runoff from an area of 950 acres on Benton Creek near Priest River, 

Idaho.

HYDROLOGIC CONDITIONS

Streamflow was generally median to excessive during most of the 1959 water year except 

for some scattered areas where it was below median at times. Flooding occurred in the 

Spokane River basin in January and a new maximum discharge of 1-6,200 cfs was reached in 

Latah Creek at Spokane on January 24. Mean monthly flows and momentary peaks resulting 

from unseasonal rains in September exceeded previous flows of record for the month in many 

tributaries in the upper Columbia River basin.

Figure 2 on page 12, for which records of two long-term gaging stations were used, 

shows a comparison of the monthly and yearly mean discharges for the 1959 water year with 

the median discharge for the period 1921-45. For Spokane River at Spokane, Wash., the 

discharges shown have been adjusted for storage.

Remarks.--Records good. Since October 1953, records include large part of flow of

McTaggart Creek, from which water is diverted at city of Tacoma diversion dam in N| 

sec.7, T.22 N., R.4 W. When flow of McTaggart Creek exceeds about 80 cfs, there is 

undiverted spill over dam. For discharges less than about 80 cfs the city allows up 

to 2 cfs to flow through pipe in dam and continue in McTaggart Creek, nut to exceed the 

natural flow of stream. No regulation.

595. North Pork Skokomish River near Potlatch, Wash.

Location.--Lat 47°19'40", long 123°14'30", in NEjW^ sec.7, T.21 N. , R.4 W. , on left bank 

1 mile upstream from mouth, 6 miles southwest of Potlatch, and 7 miles downstream from 

city of Tacoma's Cushman Dam No. 2.

Drainage area.--117 sq mi, includes 99 sq mi above Cushman Dam No. 2 which is normally 

noncontributing.

Records available. March 1944 to December 1949, February 1950 to September 1959.

Gage.--Water-stage recorder. Datum of gage is 63.49 ft above mean sea level (levels by 

city of Tacoma). Prior to Nov. 27, 1949 (destroyed by flood of Nov. 27, 1949), and 

Mar. 18 to May 9, 1950, water-stage recorder at site 200 ft downstream at present 

datum.

Extremes.--Maximum discharge during year, 3,980 cfs Apr. 29 (gage height, 7.80 ft); minimum, 6.2 cfs Aug. 14, 15 (gage height, 2.29 ft).

1944-59: Maximum discharge, 7,740 cfs Nov. 4, 1955 (gage height, 10.45 ft); minimum 

recorded, 1.3 cfs Sept. 5, 14, 16, 1951 (gage height, 2.02 ft).

flow of river normally diverted at Cushman Dam No. 2 to supply powerplant which discharges directly into sea (Hood Canal). Main portion of McTaggart Creek is diverted 

into Cushman Reservoir No. 2 and may bypass this station. Plow regulated by Lake 

Cushman (see p. 46) and by pondage in Cushman Reservoir No. 2, from which spill and 

releases are infrequent.

Records available. July 1895 to September 1959 (prior to October 1948, flow of Pock Creek 

included) . Monthly discharge only for some periods, published in WSP 1316. Published 

as "near Seattle" 1895-98, ^near Maple Valley" 1902, and as "near Ravensdale" 1898-1901, 

1903-12.

Gage. Water-stage recorder. Altitude of gage is 600 ft (from river-profile map). Prior 

To Oct. 1, 1898, staff gage at site 2£ miles downstream at different datum, far. 24, 

1901, to May 15. 1913, staff gage at site 2 miles downstream at datum 535.84 ft above 

mean sea level (levels by city of Seattle). Apr. 30, 1914, to Oct. 22, 1928, waterstage recorder a quarter of a mile downstream at different datum.

Average discharge. 64 years, 691 cfs (500,300 acre-ft per year), unadjusted.

Extremes. Maximum discharge during year, 3,460 cfs Jan. 24 (gage height, 4.92 ft); minimum, 186 cfs Oct. 27 (gage height, 0.76 ft).

1895-98, 1901-59: Maximum discharge, 14,200 cfs Nov. 19, 1911 (gage height, 10.0 ft, 

from graph based on gage readings, site and datum then in use), from computation of 

peak flow over dam, peak caused by failure of flashboards at Chester Morse Lake 

(formerly Cedar Lake); minimum observed, 83 cfs Sept. 19, 1898.

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

good. All diversions except Rock Creek returned to river above station. Roct' Creek 

which entered naturally just above station prior to 1932, has been diverted to enter 

river at a point about 2 miles downstream from Seattle municipal water-supply intake. 

Some regulation by Chester Morse Lake. Records of water temperatures for the water 

year 1959 are given in WSP 1644.

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

Average discharge.--22 years,, 2,Oil cfs (1,456,000 acre-ft per year).

Extremes. Maximum discharge during year, 15,700 cfs Apr. 29 (gage height, 13.04 ft), from 

rating curve extended above 7,700 cfs by logarithmic plotting; minimum recorded, 

581 cfs Oct. 6; minimum recorded gage height, 3.49 ft Feb. 16, 19.

1910-25, 1928-31, 1955-59: Maximum discharge, 36,800 cfs Dec. 29, 1917 (gage height, 

13.7 ft, site and datum then in use), from rating curve extended above 3,100 efs; minimum recorded, 219 cfs Dec. 15, 16, 1919.

Flood in about 1815 reached a stage about 2 ft higher than that of Dec. 29, 1917. 

Flood in 1897 reached a stage about equal to that of Dec. 29, 1917. Flood in November 

1909 reached a stage 1.6 ft higher than that of Dec. 29, 1917 (discharge, 46,200 cfs).

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

No regulation or diversion above station.

163 SKAGIT RIVER BASIN

1935. Baker River at Concrete, Wash.

Location.--Lat 48°32'35", long 121 C 44'35", on line between sees.10 and 11, T.35 N., 

R.8 E., on left bank just upstream from fish barrier, 1,500 ft downstrsam from Baker 

River powerplant, a quarter of a mile northeast of Concrete, and three-quarters of a 

mile upstream from mouth.

Drainage area.--297 sq mi.

Records available. September 1910 to March 1915, September 1943 to September 1959.

Gage. Water-stage recorder. Datum of gage is at mean sea level, datum o f 1929, supplementary adjustment of 1947. Prior to Mar. 5, 1915, staff gage at site half a mile 

downstream at different datum. Sept. 1, 1943, to Jan. 22, 1958, at site 700 ft 

upstream at datum 172.6 ft above mean sea level (from river-profile survey). Supplementary water-stage recorder on left bank about 40 ft downstream from fish barrier and 

on tailrace of powerhouse at same datum.

Average discharge.--20 years (1910-14, 1943-59), 2,614 cfs (1,892,000 acre-ft per year), 

adjusted for storage in Lake Shannon since November 1925, and Baker Lake since July 

1959.

Extremes. --Maximum discharge during year, 23,500 cfs Apr. 29, 30 (from powerplant records);

 minimum, 97 cfs Sept. 4 (elevation, 171.23 ft); minimum daily, 158 cfs Mar. 29. 

1910-15, 1943-59: Maximum discharge, 35,200 cfs Nov. 27, 1949 (gage height, 

20.32 ft, from high-water mark, datum then in use), from rating curve extended above 

16,000 cfs on basis of computation of peak flow over dam and through the powerplant 

by Puget Sound Power and Light Co.; minimum, 21 cfs Feb. 7, 1949 (gage height, 0.20 ft, 

datum then in use); minimum daily, 55 cfs Feb. 17, 1957.

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

good. No diversions which are not returned to river above gage. Flow regulated by 

Baker River powerplant and Baker and Shannon Lakes (see p. 165).

1930, staff gages, and Mar. 20, 1930, to Apr. 30, 1956, water-stage recorders at 

several nearby sites and at various datums. May 1, 1956, to Oct. 27, 1957, staff gages 

at sites within 200 ft at different datums.

Average discharge. 29 years (1930-59), 63.6 cfs (46,040 acre-ft per year).

Extremes. Maximum daily discharge during year, 760 cfs June 5; maximum observed gage 

height, 7.07 ft June 2; minimum observed discharge, 5.4 cfs Oct. 7 (gage height, 

3.21 ft).

1928-59: Maximum discharge, 1,300 cfs May 27, 1948 (gage height, 6.75 ft, site 

and datum then in use), by slope-area measurement of peak flow; maximum gage height, 

8.55 ft June 14, 15, 1933 (datum used Sept. 4, 1941, to Aug. 23, 1948), backwater 

from drift; minimum discharge, 1 cfs Nov. 29, 30, 1952, and possible other days 

during period of no gage-height record in that year.

Remarks. Records fair except thor r for periods of ice effect, shifting-control method, 

or indefinite stage-discharge relation, which are poor. No regulatio-i or diversion

Gage. Water-stage recorder. Altitude of gage is 4,660 ft (from river-profile survey). 

Prior to Apr. 30, 1942, wire-weight gage at site seven-eighths of a mile downstream 

at different datum. Apr. 30, 1942, to July 26, 1953, water-stage recorder at site 

1 mile downstream at different datum.

Average discharge. 20 years, 36.1 cfs (26,140 acre-ft per year).

Extremes. Maximum discharge during year, 890 cfs Apr. 1 (gage height, 4.50 f'~.}; maximum 

gage height, 4.89 ft Jan. 26 (backwater from ice); minimum daily discharge, 5 cfs 

Jan. 4.

1939-59: Maximum discharge, 1,800 cfs June 2, 1953 (gage height, 6.00 ft, site and 

datum then in use), from rating curve extended above 400 cfs on basis of inflowoutflow study of Nevada Creek Reservoir; maximum gage height, 7.40 ft May 29, 1953, 

site and datum then in use (backwater from diversion dam); minimum discharge, probably 

less than 2 cfs at times in 1944 and 1957.

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

which are poor. Diversions for irrigation of about 2,500 acres above station.

and datum then in use); minimum, probably less than 5 cfs Apr. 13, 1938; minimum 

daily, 32 cfs Apr. 12, 1938.

Remarks. Records excellent. Diversions above station for irrigation of about 10,000 

acres. Flathead project pumps can divert up to 12,000 acre-ft per month when 

required for irrigation of lands downstream from station. Flow regulated by Flathead 

Lake (Kerr Dam) since April 1938 (see p. 236) and Hungry Horse Reservoir since September 1951 (see p. 232).

Location.--Lat 48°05'25", long 116°03'50", In NE^SWj sec.27, T.55 N., R.3 E., on left

bank at Cabinet, 0.4 mile downstream from Cabinet Gorge Dam, 1.7 miles downstream from 

Blue Creek, and 6.5 miles southeast of Clark Fork. Measuring cableway 0.4 mile downstream. Discharge computed at Whitehorse Rapids 2.7 miles downstream'.

Drainage area.--32,067 sq mi, based on revised area of 22,006 sq mi for site near Heron.

Records available. September 1928 to September 1959. Prior to October 19^2, published 

as Cl"ark Fork near Heron, Mont.

Gage. Water-stage recorder. Datum of gage is 2,000.00 ft above mean sea Jevel, datum of 

1929, supplementary adjustment of 1947, levels by Washington Water Power Co. Prior to 

Oct. 30, 1928, staff gage and Oct. 30, 1928, to Apr. 3, 1952, water-stage recorder, at 

site near Heron, 4 miles upstream at datum 88.00 ft higher prior tu Jan. 2, 1931, and 

78.00 ft higher thereafter. Apr. 9 to Sept. 30, 1952, staff gage just upstream from 

present site at approximately same datum.

Average discharge. 31 years, 21,260 cfs (15,390,000 acre-ft per year)..

Extremes. Maximum discharge during year, 101,000 cfs June 20 (gage height, 85.40 ft); 

minimum, 860 cfs Oct. 6 (gage height, 63.90 ft); minimum daily, 1,020 cfs Apr. 4.

19S8-59: Maximum discharge, 153,000 cfs May 29 to June 1, 1943; maximum gage height, 

50.97 ft May 31, 1948, aite and datum then in use; minimum discharge observed, £70 cfs 

Aug. 12, 1952 (discharge measurement), at present, site during filling of Cabinet Gorge 

reservoir; minim.uri daily discharge since reservoir filled, 969 cfs Sept. 1, 1957.

Maximum discharge known, 195,000 cfs in June 1894 (elevation of floodmark at site 

about 4 miles upstream and an eighth of a mile below "near Heron' 1 site, 2,137,1 ft).

Remarks. Records excellent. Plow regulated by Hungry Horse Reservoir (see p. 238) and 

Flathead Lake (see p. 236). Extreme diurnal fluctuation caused by powerplant at 

Cabinet Gorge Dam. Diversions above station for_irrigation of about 354,000 acres. 

Discharge measurements Indicate approximately 1,000 cfs ground-water inflow between 

Cabinet Gorge Dam arid Whitehorse Rapids, with approximately 600 cfs of this inflow 

occurring in the 2.3 mile reach from the measuring cableway to Whitehorse Rapids. 

Records given herein represent flow at Whitehorse Rapids, computed by adding 600 cfs 

to observed flows at measuring cableway, and are considered comparable to records at 

former site near Heron, except for minor surface Inflow from additional drainage area. 

To determine flow at Cabinet Gorge Dam, 1,UOO cfs should be deducted from discharges 

published herein.

Cooperation. Gage-height record furnished and two discharge measurements made by employees ot Washington Water Power Co.

1929, supplementary adjustment of 1947. June 18, 1911, to Sept. 30, 1913, staff gages 

at Coolin at different datums. Apr. 21, 1928, to Oct. 18, 1939, staff gage at site 

400 ft north of lake outlet at present datum.

Extremes. Maximum gage height during year, 4.71 ft June 8 (contents, 160,100 acre-ft) ; 

minimum, 0.09 ft Mar. 21 (contents, 50,420 acre-ft).

1928-59: Maximum gage height, 6.46 ft May 29, 30, 1948 (contents, 202,200 acre-ft); 

minimum, -0.19 ft Feb. 7, 21, 22, 1957 (contents, 43,840 acre-ft).

Remarks. Flow from Priest Lake is regulated to hold lake at heights desirable for recreation interests during summer months and storage is released for power use downstream 

during winter months. Storage began Aug. 9, 1950. Prior to Aug. 9, 1950, some regulation resulted from logging operations in the outlet channel. Figures given herein 

represent contents above gage height of about -2 ft. Capacity table is based on area 

measured from Priest Lake quadrangle (scale 1:250,000) and reconnaissance survey of 

marginal areas and is only approximate.

bank 1,000 ft downstream from Box Canyon Dam and 4 miles north tff Ions.

Drainage area.--25,000 sq mi, approximately. 

Records available . October- 1952 to September 1959.

Qage. Water-stage recorder. Datum of gage is at mean sea level, datum of 1929, supplementary adjustment of 1947. Prior to Mar. 29, 1954, staff gage at site 300 ft 

upstream at same datum. Mar. 29 to Aug. 25, 1954, staff gage at pres3nt site and 

datum.

Extremes.--Maximum discharge during year, 99,200 cfs June 26 (elevation, 2,006.25 ft); 

minimum, 3,450 cfs Dec. 5 (elevation, 1,980.65 ft).

1952-59: Maximum discharge, 125,700 cfs June 6, 1956 (elevation, 2,011.74 ft); 

minimum, 3,190 cfs Aug. 17, 18, 20, 1958 (elevation, 1,980.5 ft, from hourly tail-water

FEND OREILLE RIVER BASIN

3985. Fend Oreille River below Z Canyon, near Metaline Falls, Wast. 

(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 Z Canyon, Ig- miles south of international boundary, 5 miles downstream from Slate Creek, and 10 miles downstream from 

town of Metaline Falls.

Drainage area. 25,200 sq mi, approximately.

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

September 1959. Prior to October 1928, published as Clark Pork at Metalire Falls and 

October 1928 to September 1937 as Clark Pork below Z Canyon, near Metaline Palls.

Gage. Water-stage recorder. Datum of gage is 1,721.18 ft above mean sea level, datum 

of 1929, supplementary adjustment of 1947 (levels by Corps of Engineers). Prior to 

Dec. 19, 1928, staff gages at Metaline Falls 10 miles upstream at datum approximately 

262.2 ft higher.

Average discharge. 47 years (1912-59), 26,710 cfs (19,340,000 acre-ft per year).

Extremes. Maximum discharge during year, 102,100 cfs June 25 (gage height, 41.86 ft); 

minimum, 3,930 cfs Oct. 2 (gage height, 9.08 ft); minimum daily, 4,290 cfs Oct. 2. 

1912-59: 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). 

Maximum stage known, 69.0 ft in June 1894, from floodmarks.

Remarks. Records excellent. In 1946 there were diversions for irrigation of about

340,000 acres, and there probably has not been any appreciable change sine? that time. 

Plow regulated at Albeni Palls and Box Canyon Dams and affected by storage in Pend 

Oreille Lake (see p. 244), Plathead Lake (see p. 236), Hungry Horse Reservoir (see 

p. 232), and several smaller reservoirs in Pend Oreille River basin in Montana (see 

following page).

Cooperation.--This station is maintained by the United States under agreement with Canada.

COLUMBIA RIVER MAIN STEM

3995. 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 sqmi, approximately.

Records available.--October 1937 to September 1959. Prior to March 1938 monthly discharge 

only, published in W3P 1316.

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 ga<re. Jan. 1 to 

May 30, 1942, auxiliary staff gage at same site.

Average discharge. 22 years, 97,750 cfs (70,770,000 acre-ft per year).

Extremes. Maximum discharge during year, 396,600 cfs June 26 (elevation, 1,328.24 ft); 

minimum, 26,700 cfs Jan. 7, Mar. 13; minimum elevation, 1,291.51 ft Mar. 13.

1937-59; Maximum discharge, 550,100 cfs June 12, 1948 (elevation, 1,338.13 ft); minmum, 18,000 cfs Feb. 7, 1954 (elevation, 1,289.38 ft).

Flood in June 1894 reached a stage of 1,346 ft, from information "by Bureau of Reclamation (discharge, 680,000 cfs).

Flow 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. Many diversions above station for irrigation. It was estimated that 346,700 acres was under irrigation in the United States in 1946. Water is 

diverted for irrigation of an additional 25,000 acres in Canada. Flow is affected by 

internationally controlled storage in Kootenay Lake as well as by natural and controlled regulation in other lakes and reservoirs in Kootenay and Pend Oreille River 

basins.

Cooperation. This station is maintained by the United States under agreement with Canada. 

Revisions (water years).--WSP 932: 1937(m), 1938(M), 1939(m).

only), February to October 1912, July 1920 to September 1959.

Sage. Water-stage recorder. Datum of gage is 2,140.19 ft above mean see level, referenced to bench mark "U.S.G.S. 2155 1911 35" (Geological Survey Bull. 567, p. 45). 

Datum of 1929, supplementary adjustment of 1947, is 3.17 ft higher. Prior to Oct. 1, 

1945, staff gages at sites 0.8 to 1.3 miles upstream at different datvms. Oct. 1, 

1945, to Feb. 21, 1949, staff gage at present site and datum.

Average discharge . 39 years (1920-59), 519 cfs (375,700 acre-ft per year).

Extremes.--Maximum discharge during year, 9,980 cfs Jan. 24 (gage height, 7.64 ft); minimum, 59 cfs Oct. 5, 6, 7.

1911-12, 1920-59: Maximum discharge observed, 23,800 cfs Dec. 22, 23, 1933, from 

rating curve extended above 4,000 cfs by logarithmic plotting; maximum gage height, 

13.4 ft probably Feb. 9, 1951, from floodmark (ice Jam); minimum disci'arge, 11 cfs 

Nov. 23, 1952 (gage height, 0.98 ft).

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

which are poor. No regulation or diversion above station.

SPOKANE RIVER BAt-IS

Location. Lat 47°46 1 , long 116°45' , in sec.lb, T.51 N., R.3 W., at Avondale and Hayden 

Lake pumping plants, l£ miles northeast of Hayden Lake.

Drainage area_.--6g.3 sq mi.

Records available.--May 1920 to September 1959.

Gage.--Staff gage read once daily. Datum of gage is 2,200.21 ft above mean sea level,

datum of 1929. Prior to Oct. 1, 1925, at datum 30.35 ft higher. Oct. I, 1925, to

Mar. 26, 1931, at datum 21.60 ft higher.

Remarks.--Water is pumped from lake for irrigation and domestic supply. Lake has no

natural surface outlet, but due to the permeability of the lakebed, a considerable part 

of the total inflow leaves the lake by infiltration to the ground water of Rafidrum 

Prairie. Surface flow observed leaving lake starting Jan. 26 and continuing for an 

unknown period through a controlled culvert in the dike at southwest corner of lake. 

Flow escaped through a break in the dike Apr. 23 to May 8. This water seeped rapidly 

into the ground in an extremely permeable area adjacent to the outflows.

Revisions (water years) .--WSP a62: 1921(M). WSP 1216: 1950.

SPOKANE RIVER BASIN

4190. Spokane River near Post Falls, Idaho

Location. Lat 47°42'10", long 116°58'40", in SW^SW^ sec.4, T.50 N. , R.5 W. , on right bank 

1 mile downstream from powerplant of Washington Water Power Co., 1-J- miles downstream 

from intake of Spokane Valley Farms Co. 's canal, and if miles southwest of Post Falls.

Drainage area.--3.340 sq mi, approximately, of which about 122 sq mi in the vicinity of 

Hayden Lake is noncontributing to this station.

Records available.--January 1913 to September 1959. Prior to October 1949, published as 

"at Post Falls."

Gage.--Water-stage recorder. Datum of gage is 2,000.00 ft above mean sea level, referenced to same datum as gage on Coeur d'Alene Lake at Coeur d"Alene (see p. 277). 

Datum of 1929, supplememtary adjustment of 1947, is 3,00 ft higher. Jan. 1, 1913, to 

Nov. 21, 1920, staff gage, and Sept. 16, 1934, to Nov. 15, 1949, water-stage recorder, 

at site 0.8 mile upstream. Nov. 22, 1920, to Sept. 15, 1934, water-stage recorder at 

site 0.6 mile upstream. All gages at present datum.

Average discharge. River only, 46 years, 6,152 cfs (4,454,000 acre-ft per year); combined 

river, Spokane Valley Farms Co.'s canal, and Rathdrum Prairie Canal, 46 years, 6,259 

cfs (4,531,000 acre-ft per year).

Extremes.--Maximum discharge during year, 27,000 cfs May 5 (gage height, 69.96 ft); minimum, 114 cfs Oct. 5, 6 (gage height, 55.14 ft).

1913-59: Maximum discharge, 50,100 cfs when recorder was not operating Dec. 25, 

1933 (determined from unpublished records collected by Washington Water Power Co. for 

station at Liberty Bridge); minimum daily, 104 cfs Aug. 18, 1958.

Remarks. Records excellent except those below 1,500 cfs, which are good. Spokane Valley 

Farms Co.'s canal (see preceding page) and Rathdrum Prairie Canal (see p. 280) divert 

water above gage for irrigation. Figures of daily discharge do not include water 

diverted by these canals. Flow regulated by dam at Post Falls and affected by storage 

in Coeur d'Alene Lake (see p. 277).

Cooperation.--Water-stage-recorder graph furnished by Washington Water Power Co.

a quarter of a mile downstream from Twisp River and 0.0 mile east of center of Twisp.

Drainage area. 1,330 sq mi, approximately.

Records available. June 1919 to September 1959. Monthly discharge only for some periods, published in WSP 1316.

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

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

Oct. 2, 1919, to Sept. 30, 1929, and Oct. 31 to Nov. 6, 1933, chain gage on road bridge 

40 ft upstream at same datum as staff gages. Nov. 7 to Dec. 18, 1933, staff gage at 

present site at different datum.

Average discharge.--40 years, 1,329 cfs (962,200 acre-ft per year).

Extremes. Maximum discharge during year, 10.700 cfs June 3 (gage height, 6.92 ft); minimum, 278 cfs Oct. 1 (gage height, 1.54 ft).

1919-29, 1933-59: Maximum discharge, 40,800 cfs May 29, 1948 (gage height, 12.94 ft 

in gage well), from rating curve extended above 18,000 cfs on basis of slope-area 

measurement 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, 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. Diversions 

for irrigation of 7,410 acres above station (1946 estimate).

CHELAN RIVER BASIN 321

4525. Chelan River at Chelan, Wash.

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

bank in forebay upstream from control dam at outlet of Lake Chelan, a quarter of a mile 

south of Chelan.

Drainage area.--9Sl sq mi.

Records available.--November 1903 to September 1959. Published as "below Chelan Lake"

1904-5. Adjusted records for October 1903 to September 1911, published in WSP 482, 492, 

and 870, have been found to be unreliable and should not be used.

Gage. Water-stage recorder and concrete power dam. 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 datum. Oct. 1, 1927, to Nov. 10. 1928, staff gage and Nov. 11, 1928, to Far. 19, 

1939, water-stage recorder at sites 2j- miles downstream at same datum.

Average discharge. 55 years (1904-59), 2,051 cfs (1,485,000 acre-ft per year), adjusted 

for storage since October 1911.

Extremes.--Maximum daily discharge during year, 12,500 cfs June 21; minimum daily, 65 cfs

1903-59: Maximum daily discharge, 16,000 cfs May 30, 1948; no flow for 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. Chelan County Public Utility District No. 1 diverts witer at 

Chelan to develop about 54,000 horsepower and to irrigate an unknown area near Chelan, 

which quantity is included in records of daily discharge. Diversions for irrigation 

of about 6,280 acres, depletion 11,000 acre-ft (1946 estimate). Flow regulated by 

Lake Chelan (see preceding page).

Cooperation.--Records of water used for power and irrigation furnished by the Public 

Utility District No. 1 of Chelan County.

bank on downstream side of highway bridge, 3 miles upstream from Parker Horn and 

4 miles north of town of Moses Lake.

Drainage area.--About 2,040 sq mi.

Records available. September 1942 to September 1959.

Gage. Water-stage recorder. Datum of gage is 1,070.39 ft above mean sea level (Bureau 

of Reclamation bench mark). Prior to July 14, 1956, at site 300 ft upstream at same 

datum.

Extremes. Maximum discharge during year, 5,000 cfs Jan. 27 (gage height, 5.96 ft); minimum, 5.9 cfs Jan. 2 (gage height, 1.36 ft), result of freezeup.

1942-59: Maximum discharge, 10,400 cfs Feb. 28, 1957 (gage height, 6.81 ft); no 

flow for several months each year prior to 1952, and part of each day Jan. 14, 15, 1953.

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

which are fair. Numerous small diversions for irrigation and domestic use above 

station. Most of natural flow from upper basin passes this station underground. No 

regulation. Beginning in 1952, return flow from irrigation on Columbia Basin project 

has increased runoff during summer months.

CRAB CREEK BASIN 

4715. Crab Creek near Warden, Wash.

341

Location. Lat 46°57'00", long 119°15'20", in SW^NW^ sec.24, T.17 N., R.28 E. , on left 

bank half a mile east of Goose Lake, 2£ miles downstream from 0'Sullivan Dam, and 

10 miles west of Warden (revised).

Drainage area.--About 4,150 sq mi, of which 500 sq mi in the vicinity of Soap Lake is 

probably noncontributing.

Records available. June to December 1909, March to December 1910, February to December 

1911, February to June 1912, October 1942 to September 1952, October 1955 to September 

1959. Published as Lower Crab Creek near Warden 1909-12. Records for Septembe" 1952 

to September 1955 at site 2 miles upstream not equivalent owing to seepage bypassing 

gage.

Gage_. -^Water-stage recorder and timber control; prior to May 8, 1958, rock and culvert 

. control. Altitude of gage is 880 ft (from topographic map). Prior to June 27, 1912, 

staff gages at several sites within 3 miles of present station at various datunn. 

October 1942 to September 1950, water-stage recorder at site 1.6 miles upstream at 

different datum. October 1950 to September 1952, water-stage recorder at site 2 miles 

upstream at different datum.

Extremes. Maximum discharge during year, 174 cfs Apr. 30 (gage height, 3.43 ft), caused 

by partial failure of Pish and Wildlife Service Dam half a mile upstream, from rating 

curve extended above 72 cfs; minimum, 9.2 cfs Jan. 3 (gage height, 1.96 ft); minimum 

daily, 11.5 cfs Apr. 26.

1909-12, 1942-52, 1955-59; Maximum discharge, 3,000 cfs Feb. 7, 1943 (gage height, 

4.25 ft, site and 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 

0'Sullivan Dam.

Remarks.--Records good. Many diversions for irrigation. Plow regulated by Potholes Reservoir and partially by Fish and Wildlife Service Dam since January 1958. Storage began 

in Potholes Reservoir in September 1952 and from this time until September 1955 the 

flow consisted of a small part of dam seepage. Discharge at present location includes 

essentially all of the seepage.

Lake is probably noncontributing.

Records available.--August 1942 to November 1959 (discontinued).

Gage.--Water-stage recorder. Datum of gage is 530.33 ft above mean sea level (Bureau of 

Reclamation bench mark).

Extremes.--1958-59: Maximum discharge during water year, 143 cfs Jan. 13 (gage height, 

3.44 ft); minimum, 17.5 cfs Jan. 3 (gage height, 1.47 ft), result of freeseup.

1959; Maximum discharge during period October to November, 84 cfs Nov. 22 (gage 

height, 2.88 ft); minimum, 24 cfs Nov. 16 (gage height, 1.69 ft).

1942-59: Maximum discharge, 3,300 cfs Feb. 5, 1943 (gage height, 7.5 ft, estimated 

by observer), from rating curve extended above 1,000 cfs; possibly no flow at times 

during summer of 1947.

Remarks.--Records good. Many diversions above station for irrigation. Flow is entirely 

regulated by Potholes Reservoir. Flow by station is essentially seepage from Potholes 

Reservoir and return flow from part of the Columbia Basin project. Fecords of chemical 

analyses arid water temperatures for the water year 1959 are given in WSP 1644.

Revisions.--WSF 121C: Drainage area.

344 YAKIMA RIVER BASIN

4745. Yakima River near Martin, Wash.

'10", long 121°20'10", in NE£ sec.12, T.21 N., R.ll E., on left bank 

from dam at outlet of Keechelus Lake, 3^ miles northwest of Martin,

Location.--Lat 47°19 

800 ft downstream 

and 9i miles northwest of Easton.

Drainage area.--55.8 sq mi.

Records available.--October 1903 to September 1959.

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

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

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

Average discharge.--56 years, 333 cfs (241,100 acre-ft per year), adjusted for storage 

since January 1906.

Extremes. Maximum discharge during year, 1,320 cfs June 5; maximum gage height, 8.23 ft 

May 8; minimum discharge, 1.0 cfs Nov. 1-3 (gage height, 2.09 ft).

1903-59: Maximum discharge, 7,370 cfs Mar. 26, 1915, when temporary crib dam was 

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

Remarks.--Records good. Flow regulated by Keechelus Lake (see p. 362). Keechelus Lake 

spillway discharge, computed from reservoir elevations and spillway rating, bypasses 

gage and is added to flow at station. No diversion above station.

Cooperation.--Gage-height record, 12 discharge measurements, and records of daily discharge furnished by Bureau of Reclamation; 1 discharge measurement male and records 

reviewed by Geological Survey.

Revisions (water years). WSP 1216: Drainage area. WSP 1286: 1910.

sharp-crested weir since September 1934. Altitude of gage is 2,450 ft (from topographic map). Prior to Sept. 20, 1934, staff gage or water-stage recorder at site 

50 ft upstream at different datum.

Average discharge.--35 years (1909-15, 1930-59), 69.0 cfs (49,950 acre-ft per year).

Extremes. Maximum discharge during year, 239 cfs June 3 (gage height, 1.48 ft); minimum,

 8.3 cfs Jan. 3 (gage height, 0.19 ft), result of freeseup.

1907-59: Maximum discharge, 823 cfs May 20, 1956 (gage height, 3.00 ft); minimum, 

5.0 cfs Nov. 14, 15, 1944, Jan. 20, 1945 (gage height, 0.18 ft), but may have been 

less during periods of ice effect.

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

which are fair. No diversion of importance. No regulation.

Cooperation.--Gage-height record, 20 discharge measurements, and records of daily dis-

 charge furnished by Bureau of Indian Affairs; 7 discharge measurements made and records 

reviewed by Geological Survey.

YAKIMA RIVER BASIN

Location. Lat 46°29'4u", long 120°2fi'10", in sec.28, T.12 N., R.19 E.. on left bank

700 ft downstream from Sunnyside diversion dam, l-=r miles east of Parker, and 3 miles 

downstream from Ahtanum Creek.

Drainage area.--3.650 sq mi, approximately.

Records available.--April 1908 to September 1959. Monthly discharge only for some periods, 

published in WSP 1316. Prior to October 1916, published as "near Wapato."

Gage.--Water-stage recorder. Datum of gage is 886.23 ft above mean sea level (Bureau of 

Reclamation bench mark). Prior to Jan. I, 1909, hook gage at site 25 ft above headgate of Sumiyside Canal at different datum. Jan. 1, 1909, to Dec. 31, 1913, chain 

gage at site 500 ft downstream from Sunnyside Canal at datum 1.82 ft higher than 

present datum. Jan. 1, 1914, to Aug. 16, 1915, chain or staff gage and Aug. 17, 1915, 

to Feb. 2, 1919, water-stage recorder, at site 500 ft downstream from headgate of 

Sunnyside Canal at datum 0.18 ft lower than present datum. Feb. 3, 1919, to Oct. 20, 

1940, water-stage recorder at present site at datum 0.18 ft lower than present datum. 

Oct. 21, 1940, to Aug. 9, 1953, water-stage recorder at site 1,000 ft downstream from 

headgate of Sunnyside Canal at datum 0.18 ft lower than present datum.

Extremes. Maximum discharge during year, 11.000 cfs Jan. 25 (gage height, 8.83 ft); minimum, 31 cfs Oct. 2 (gage height, 1.85 ft); minimum daily, 38 cfs Oct. 3.

1908-59: Maximum discharge, 65,000 cfs Dec. 23, 1933 (gage height, 15.0 ft, from 

high-water marks); minimum, less than 10 cfs for several days during latter part of 

irrigation season in most years prior to 1936.

Remarks. Records excellent except those for periods of twice-daily staff-gage readings, 

which are good. Diversions above station for irrigation of about 200,000 acres above 

and 220,000 acres-below station. During irrigation season when Sunnyside Canal is 

carrying water, as much as 113 cfs, depending upon stage of the canal, is released 

ahead of the fish screens and passes river and canal gaging stations unmeasured. For 

combined flow of Yakima River and canals see following page. Some regulation by 

diversions and by Keechelus, Kachess, Cle Elum, and Bumping Lakes, and Tieton Reservoir (see p. 362).

Cooperation.--Gage-height record collected in cooperation with, and 24 discharge measurements furnished by Bureau of Reclamation.

Revisions (water years). W3F 982: 1942. WSP 1122: 1934. WSP 1216: 1949-50, drainage

gages at approximately same site and datum. Feb. 6, 1933, to July 26, 1934, tape gage 

at present site and datum.

Extremes. Maximum discharge during year, 10,800 cfs Jan. 26 (gage height, 9.17 ft); min-

 imum, 1,020 cfs July 17 (gage height, 3.38 ft).

1896-1915, 1933-59: Maximum discharge, 67,000 cfs Dec. 23, 1933 (gage height, 

21.57 ft, from high-water marks); minimum observed, 105 cfs Sept. 11, 1906 (gage 

height, 2.35 ft, datum then in use).

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

Water diverted above station for irrigation of about 424,000 acres. Some regulation 

by diversions and by Keechelus, Kachess, Cle Elum, and Bumping Lakes, and Tieton reservoir (see following page). The Kiona Canal bypasses station with a mean flow of 

approximately 23 cfs for irrigation of about 1,100 acres below station. Diversion by 

Kennewick Canal was 75,080 acre-ft in water year 1959. Records of che.mical analyses 

and water temperatures for the water year 1959 are given in WSP 1644.

366 DISCHARGE AT PARTIAL-RECORD STATIONS AND MISCELLANEOUS SITES

As the number of streams on which streamflow information is likely to be desired far 

exceeds the number of stream-gaging stations feasible to operate at one time, the Geological Survey collects limited streamflow data at sites other than stream-gaging stations. 

When limited streamflow data are collected on a systematic basis uver a period of years 

for use i 

partial-r 

flow or f

charge measuremens are mae a oer ses no ncue n e para . 

These measurements are generally made in times of drought or flood to give better areal 

coverage to those events. Those measurements and others collected for some special reason 

are called measurements at miscellaneous sites.

Records collected at partial-record stations are generally presented in two tables.

Crest-stage partial-record stations

The following table contains annual maximum discharges for crest-stage stations. A 

crest-stage gage is a device which will register the peak stage occurring between inspections of the gage. A stage-discharge relation for each gage is developed from discharge 

measurements made by indirect measurements of peak flaw or by current meter. The date of 

the maximum discharge is not always certain but is usually determined by comparison with 

nearby continuous-record stations, weather records, or local inquiry. Only the maximum 

discharge for each water year is given. Information on some lower floods may have been 

obtained but is not published herein. The years given in the period of record represent 

water years for which the annual maximum has been determined.
