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

BASIN, 1943

SCOPE OF WORK

This volume is one of a'series of 14 reports preseftting results of measurements of 

stage and flow made on streams,, lakes, and reservoirs in the United States during the 

water year ending September 30, 1943. The work was begun in 18S8 in connection with 

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

stage and contents of lakes and reservoirs have been made at about 9,670 gaging stations 

In the 48 States and also at many in the Territories of Alaska and Hawaii. In July 1943, 

5,130 gaging stations, including those in Hawaii, were being maintained-by the Geological 

Survey and cooperating organizations. Miscellaneous discharge measurements were made during the water year at many other points. »

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

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

kind is acknowledged in connection with the description cf each station affected; cooperation of the second kind is acknowledged, under the heading "Cooperation," in the introductory matter that precedes the gaging-staticn records in each volume. In the present volume, the section on cooperation of the second kind appears on page n.

DEFINITION OF TEW®

The units in which stream-flow data are presented in this report and other terms used 

herein are defined as follows:

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

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

whose average velocity is 1 foot per second.

*Second-feet per square mile" is the average number of cubic feet of water flowing per 

second from each square mile cf area drained, en theiassumption that the runoff is distributed uniformly both as*regards time and area.

"Runoff in inches" Is the depth to which an area would be covered if all the water 

draining from It In a given period were uniformly distributed on Its surface. It Is used 

for comparing runoff with rainfall, which Is usually expressed In inches.

An "acre-foot" is the quantity of water required to cover an acre to the depth of 1

V '

foot and is equivalent to 43,560 cubic feet. The term is commonly used in connection with 

storage for irrigation. ,

"Second-foot-day" Is the volume of water represented by a'flow of 1 second-foot for 24 

hours. It is equivalent to 86,400 cubic feet, 1.983471 acre-feet, or 646,3,17 gallons and 

represents a runoff of 0.0372 inch from 1 square mile. '

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

height and discharge,"

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

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

of the channel, or an artificial structure.

1
2 ' SURFACE WATER SUPPLY, 1943, PART 12

"Contents" Is a term applied to the volume of water in a reservoir, not Including water 

in bank storage unless so indicated.

EXPLANATION OF DATA

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

discharge, and general Information used to supplement the records of stage and discharge 

measurements in determining the dally flow. The records of stage are obtained either from 

direct readings on a nonrecording gage or from a water-stage recorder that gives a continuous record of the fluctuations. Measurements of discharge are made with a current ' 

meter by-the general methods outlined in standard textbooks on the measurement of river 

discharge.

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

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

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

I change in the physical features that form the control, the dally mean discharge is,

determined by the "shifting-control method," in which correction factors based on individual discharge-measurements and notes by engineers and observers are used in applying the 

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

may be temporarily changed by the presence of aquatic growth or debris on the control. 

For such times the dally mean discharge is computed by what Is essentially the "shifting- - 

control" method, described above.

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

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

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

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

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

change of. stage is used as a factor in1 the determination of discharge.

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

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

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

occasional winter discharge measurements, consideration being given to the available In1 formation on temperature and precipitation, notes by gage observers and engineers, and 

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

included in the periods of ice -effect and the days during the winter period on which discharge measurements were made are indicated in the table by symbols referring to footnotes 

or are given in a general note following the table. 

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

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

the stream, and a table of monthly and yearly discharge and runoff. Skeleton rating 

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

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

or other special methods.
TIME BASIS , ' 3

The descrlptlpn of the station-gives the type of gage, Its latitude and longitude as 

determined from the best available maps, and Information In regard to diversions that > 

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

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

 number of years indicated. N it is given only for stations for which there are 10 or more 

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

height; the minimum discharge If there le little or no regulation; the minimum dally dls-

/ 

charge if there Is extensive regulation (also the minimum discharge If useful};, and the

.minimum gage height (unless it Is of no importance). Unless otherwise qualified, the 

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

recorder or a nonrecordlng gage read at ttie time of the crest. Likewise the minimum dis- 1 

charge represents the lowest stage, unless otherwise qualified. Selected peak discharges 

' with the times of their occurrence areglven below the table of monthly discharge for some 

stations. This supplementary Information Is generally omitted for a station at which the 

drainage area cf the stream Is less than 10 or more than 10,000 square miles or at which, 

on most days, the peak discharge exceeds the mean discharge by less than 10 percent.

For stations equlppad with water-stage recorders, except t\ose on streams subject to 

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

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

«

not indicate the true dally mean discharge, which must be obtained by averaging the discharge fcr parts of the day or by using the discharge Integrator, an instrument for obtaining the daily mean discharge from a continuous* gage-height gxfeph and containing as an 

essential element a curve representing the stage-discharge-relation at the station. For 

stations equipped with nonrecordlng gages, the table of daily discharge gives the discharge' 

In second-feet corresponding ,to once-nlally, readings of the gage or the mean of twice-daily 

readings. For periods of rapidly changing stage the daily mean discharge Is determined 

from gage-height graphs based on gage readings made once or twice daily or oftener, as 

Stated In the station description.

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

for each month of the figures given in the table of daily discharge, The column headed

"Maximum" gives the maximum dally discharge, not the momentary discharge when the water i 

surface was at crest stage. Likewise, In the 'Column headed "Minimum" the quantity given

is the minimum dally discharge. The column headed "Mean" gives the average flow In cubic 

feet per second during the month.

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

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

usually given }n the first report In which data for a station are published but Is omitted 

from succeeding reports. .

i - TIME BASIS

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

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

ahead 1 hour, oh to 3 a.m. Records of dally discharge prior to February 9, 1948, were computed on the basis of standard time. Records subsequent to that date have been computed on 

the basis of war time. To convert war time to standard time, subtract' 1 hour. ' *
4 SURFACE WATER SUPPLY, 1943, PART 12

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

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

and (2) the accuracy of observations of stage, measurements of f^pw, and interpretation of 

records.

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

records. "Excellent""indicates, that, in general, the 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 accurate than the daily records.

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

owing to diversion, consumption, regulation by storage, increase or decrease in evaporation due to artificial causes, or other factors. For such stations figures <yt "secondfeet per square mile" and "runoff in inches" are not published unless storage or diversion 

records are included indicating the extent of the regulation or diversion or unless 

satisfactory adjustments can be made for changes in contents of reservoirs or for other 

changes incident to use and control. Evaporation from a reservoir is not included In the 

adjustments for changes in reservoir contents, unless its Inclusion is indicated. Figures 

of secend-feet per square mile and runoff in inches are also omitted if the drainage area 

includes large noncontributing areas or if the average annual rainfall over the drainage 

area is less than 20 inches.

Many gaging stations on streams in the irrigated areas of the united States are situated above most of the diversione from those streams, and therefore the discharge recorded 

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

below the station must firet be satisfied.

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

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

of the variation in flow. "Ae further observations in each succeeding year may be* 'expected 

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

are subject to revision in succeeding water-supply papers.

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

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

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

station was maintained. For example, the data for 1910 to 1920 for any station In the 

area covered by part 3 are published In Water-Supply Papers 283, 303, 323, 353, 403, 433, 

458, 473,, and 503, which contain records for the Ohio River Basin for those years,

The- records at most of the stations discussed In" these reports extend over_a series of 

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

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

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

relative order as the streams and «aglng stations In the body, of the report. An Index of 

the records obtained prior to 1904 has been published In Water-Supply Paper lie.

Each of the reports on surface-water supply for the'year 1939, issued as Water-supply 

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

stations In the area covered by that report. Gaging stations at which 10 or more, com- . 

plete years of record have been collected are represented. _ These summaries are .available

t Records 'for earlier years published in water-supply papers of Geological Survey.

Note.- Records of daily discharge for many canals and drains in Washington for 1943 and 

earlier years have been collected by the Bureau of Reclamation and the Office 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 Soil Conservation Service 

of the United States Department of Agriculture began in 1932 to make studies of runoff 

from one area of about 760 acres and three areas of less than 70 acres each near Pullman, 

Wash., and in 1939 from one area of 19.2 acres near Dayton, Wash. These records are in 

the files of the Soil Conservation service. The Northern Rocky Mountain Forest and Range 

Experiment Station collects records of-runoff from an area of 960 acres on Benton Cr,eek 

near Priest River, Idaho.

COOPERATION . X ' ,The work in the several States was done under cooperative agreements with the organizations listed below:

Idaho: Idaho1 Department of Reclamation, E. V. Berg, commissioner, until 

December 1942, succeeded by James Spofford, State reclamation engineer.

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

Board'. ^

Washington: state Department of Conservation and Development, Ed Davls,

.director, and c. J. Bartholet, supervisor of hydraulics, Division of Water

! '

Resources; State Department of Fisheries, F. J. Foster, director; State Department of Game, B. T. McCauley, director; cities of Aberdeen, Bellingham, Everett, 

Seattle, and Tacoma; King and Pierce Counties, through the In1;ercounty River 

Improvement Commission; Skagit County Public Utilities District No. 1; and Skagit, ' 

Snohomish; and Whatcom Counties.

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

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

Acknowledgment "of financial assistance in collecting records published herein Is due ' 

also to the united States Department of State; Bureau of Reclamation, Office of Indian 

Affairs, and Bonneville Power ^ministration, United States Department of the interior; 

Forest Service and Soil Conservation Service, United States Department of Agriculture; 

Weather Bureau, United states Department of Commerce; and the Federal Power Commission.

Full cooperation exists between this organization and the Dominion water and Power 

Bureau, Department of Mines and Resources, Canada. On waters adjacent to the international 

boundary certain stations are maintained Jointly by the United States and Canada under the 

terms of the Boundary Waters Treaty of lp09, and others are maintained under a subsequent 

agreement between the two Governments. The records from all these stations are obtained In 

such a manner as to be equally acceptable and available in either country. These stations 

are herein designated 'international gaging stations.*

Assistance In.collecting the records was also rendered by the_following organizations: 

Idaho: Washington Water Power Co.

Montana: Montana Power Co. t 

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

& Light Co.; and Washington water Power Co.

DIVISION OF WORK

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

Sunjey, Olenn L. Parker, chief hydraulic engineer, Carl G. Paulsen, assistant chief 

hydraulic engineer, and Rudolph 0. Kasel, chief of the division of surface waters. The 

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

under supervision of district engineers as follows: In Idaho and for Clark Fork nsar 

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

Washington, p. M. Veatch. . j , -

fron tlewhalem Creek, 11 miles upstream from Bacon Creek, and 16 miles upstream from

Marblemount . Datum of gage Is 400 feet above mean sea level, subject to adjustment to

datum of 1929.

Drainage area.- 1,160 square miles, of which 390 square nlles is in Canada. 

Records available.- December 1908 to May 1914 and October 1920 to September 1943 in reports

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

Water-Supply Bulletin 5. 

Average discharge.- 35 years, 4,303 second-f«et (adjusted for storage in Diablo Reservoir

since October 1929 and Ruby Reservoir since March 1940). 

Extremes.- Italmum discharge during year, 20,400 second-feet (regulated) May 27 (gage

height, 88.82 feet); minimum, 157 second-feet (regulated) Nov. 6 (gage height, 78.74

feet); minimum daily, 698 second-feet (regulated) Nov. 7.

1908-14, 1920-43: Maximum discharge, 60,000 second-feet Dec. 12, 1921 (gage height,

94.2 feet); minimum, 74 second-feet (regulated) Nov. 10, 1956 (gage height, 78.39

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

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

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

partly regulated by Diablo and Ruby Reservoirs (see p. 85), having a combined capacity

of 179,100 acre-feet. 

Cooperation.- Gage-height record collected in cooperation with and many discharge measurements furnished by city of Seattle.

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

Records available.- September 1924 to September 1943.

Average discharge.- 19 years, 14,050 second-feet (adjusted for storage in Lake Shannon 

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

since March 1940).

Extremes.- Ifeximum discharge during year, 54,000 second-feet (regulated) Nov. 23 (gage 

height, 26.69 feet); minimum, 2,580 second-feet (regulated; Oct. 26 (gage height, 

12.63 feet); minimum dally, 2,930 second-feet (regulated) Oct. 25.

feet, present datum); minimum, probably.less that 2,160 second-feet during period 

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

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

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

500,000 second-feet), occurred about 1815. Records of other floods prior to establishment of station are given in Water-supply Paper 612.

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

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

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

(see p. 85). Records of daily discharge not adjusted for change in contents of 

reservoirs.

* Winter discharge measurement made on this day. i

a No gage-height record; discharge determined on basis of gage-height record for former station at

b Stage-discharge relation affected by ice.

Time basisi Pacific war time. To convert war time to standard time, subtract 1 hour.
COLUMBIA RIVER MAIN STEM 107

Columbia River at international boundary 

(International gaging.station)

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

N., R. 41 E., at international boundary, half a mile downstream from Pend Oreille 

River. Auxiliary water-stage recorder 2.2 miles downstream. Datum of gages is at 

mean sea. level (Bureau of Reclamation 1937 datum)'.

Drainage area.- 59,700 square miles.

Recoras available.- March 1938 to September 1943.

Extremes.- 1941-42: Maximum discharge during water year, 275,000 second-feet June 12, 16; 

maximum elevation', 1,320.06 feet June 16; minimum discharge, 32,600 second-feet Mar. 4 

(elevation, 1,292.56 feet).

1942-43: Maximum discharge during water year, 291,000 second-feet July 7 (elevation, 1.321-.47 feet); minimum, 26,200 secona-feet Mar. 23 (elevation, 1,291.54 feet).

1938-43: Maximum discharge, 334,400 second-feet June 27, 28, 1938 (elevation, 

1,324.00 feet); minimum observed, 21,500 second-feet Feb. 10, 1939 (elevation, 

1,290.12 feet).

Flow of about 12,900 second-feet occurred-Jan. 30 or 31, 1937, based on information 

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

1,291.6 feet); may have been as low sometime in January 1930.

Remarks.- Records excellent. After June 6, 1942, discharge computed using fall in reach 

between base and auxiliary gages as a factor. Many diversions above gage-for irrigation but quantity very small percentage of flow past gage. Some fluctuation at low 

flow caused by power plant on Kootenal River. Flow affected by regulation in Kootenai 

and Pend Oreille River Basins.

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

States under agreement with Canada.

Columbia River at Grand Coulee Dam, Wash.

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

36, T. 29 II., R. 30 E., in pier 3 of highway bridge, 2,500 feet downstream from Grand 

Coulee Dam and 14 Riles upstream from IJespelem River. Datura of gage is at mean sea 

level, datum of 1929.

Drainage area.- 74,100 square miles.

Records available.- April 1913 to September 1943 (monthly discharge only, April 1913 to 

June 1923, January 1924 to Ifey 1928).

Average discharge.- 30 years, 106,600 second-feet (adjusted for change in contents in 

Columbia River Reservoir beginning October 1939).

Extremes.- Maximum discharge during year, 319,900 second-feet (regulated) June 21 (elevaFToh. 969.53 feet); Minimum, 27,700 second-feet (regulated) Mar. 25 (elevation, 935.18 

feet).

1913-43: Maximum discharge, 492,000 second-feet June 15, 1913 (computed on basis 

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

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

relation was affected by ice.

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

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

of flow past gage. Flow regul.ited by Columbia River Reservoir (see p. 109 ) and reservoirs in Kootenai, Fend Oreille, and Spokane River Basins. .

* Winter discharge measurement made on this day.

Hote.- Channel conveyance affected by Ice Hov. 24 to Dec. 17, Dec. 26 to Mar. 27; discharge computed on basis of 4 discharge measurements and reeords for station at Bonners Perry, Intervening 

Inflow, and channel storage.

Time basis; Pacific war time. To convert war time to standard time, subtract 1 hour.,

Kootenai River at Port Hill, Idaho 

(International gaging sta'tlon)

Location.- Water-stage recorder, lat. 49°00'00", long. 116°30no", In SWJ sec. 8, T. 65 

N., R. 1 W., 300 feet south of International boundary at Port Hill. Datum of gage is 

1,700.X feet above mean sea level (U. 8. Coast and Geodetic Survey datum) and 

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

1938).

Drainage area.- 13,700 square miles.

Records available.- May to July 1904, October 1927 to April 1920 (gage heights only) and 

April 1920 to September 1943 In reports of Geological Survey. October 1924 to September 

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

Mines and Resources, Canada.

Average discharge.- 15 years, 14,240 second-feet

Extremes.- mxlnuEI ?ally discharge during year, 60,200 second-feet Apr. 21; maximum elevation; 1,758.39 feet June 20; minimum dally discharge, 2,040 second-feet Jan. 19; minimum 

elevation, 1,738.96 feet Mar. 23.

1928-43: Maximum daily discharge, 93,200 second-feet June 19, 1933; maximum eleva- " 

tlon, 1,764.08 feet May 31, 1930; minimum dally discharge, 1,380 second-feet Feb. 8, 

1936; minimum elevation, 1,738.69 feet Mar. 10, 1939.

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

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

Daily discharge, represents entire flow passing International boundary, computed by 

adding tributary Inflow, including that of Boundary Creek, to flow at station near 

Cope.land. Boundary dike of Reclamation Farm and Forest Service roadway (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.

Cooperation.- This station Is one of the Inte'rnational gaging stations maintained by 

United States under agreement with Canada.

Tonasket.

Drainage area.- 7,250 square miles. 

Records available.- April 1929 to September 1943. May 1911 to September 1,925 (equivalent

records at site a quarter of a mile upstream from Salmon Creek at Okanogan, published

as Okanogan River at Okanogan) in reports of Geological Survey. June 1911 to

September 1933 In State Water-Supply Bulletin 5. 

Average discharge.- 23, years (1911-25, 1929-43), 2,704 second-feet, 

extremes.- naximuln discharge during year, 13,500 second-feet June 11 (gage height, 13.41

reetj; minimum discharge, 395 second-feet Sept. 17, 18,

1911-25, 1929-43: Maximum discharge recorded, 25,400 second-feet Apr. 27, 1934

3.43 feet). 

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

record, which are poor. Many diversions above station for irrigation. Some regulation

by Okanagan Lake as an aid to navigation. Some diurnal fluctuation of low flow caused

by power plant on Similkameen River. 

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

the united States under agreement with Canada.

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

rair. Wenatchee Park Land & Irrigation Co. diverts a maximum of about 12 second-feet 

from Chiwawa River during Irrigation seasons. Natural regulation by Wenatchee Lake; 

late summer flow may be slightly influenced by fish weir at lake outlet.
