year ending September 30, 1955. 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 13,250 gaging stations in the 48 States and at many others in the Territories of Alaska and Hawaii. On September 30, 1955, the Geological Survey and cooperating 

organizations were maintaining 6,860 gaging stations, including those in Alaska and Hawaii. 

Discharge measurements only were made at many other points in the 1955 water year, most of 

which are published at the end of each report. The name of each stream measured at points 

other than gaging stations is not listed in the index to this report. Only the major river 

basins in which measurements were made are listed under the item "Discharge measurements" 

in the index.

DIVISION OP 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

Idaho.......................... Boise......................... 429 Federal Building.

Montana........................ Helena........................ 409 Federal Building.

Washington..................... Tacoma........................ 207 Federal Building.

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records of discharge prior to publication, and other unpublished data concerning the 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

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 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. The term is used 

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

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

is equivalent to 43,560 cubic feet. The term is commonly used in relation to storage for 

irrigation.

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.
EXPLANATION OF DATA 3

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 noncontributing 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 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 OF DATA 5

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

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

logarithmic plotting. The application of the dally mean gage height to those rating 

tables gives the dally mean discharge, from which the monthly and the yearly mean discharge are computed. If the stage-discharge relation Is subject to change because of 

frequent or continual change In the physical features that form the control, the dally 

mean discharge Is determined by the shifting-control method, In which correction factors 

based on Individual discharge measurements and notes by engineers and observers are used 

In applying the gage heights to the rating tables. If the stage-discharge relation for a 

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

the dally 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 In 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 

dally records Is not changed.

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

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

runoff 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 1955 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
6 SURFACE WATER SUPPLY, 1955 , PART 12

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 gage 

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 creststage 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 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) 11 

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. 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
ACCURACY OF FIELD DATA AND COMPUTED RESULTS 7

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 headed "Mean" gives 

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

expressed ta 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 area includes 

large noncontributing 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.

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 AMD 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

4Z8Z7Z O - 57 - Z
8 SURFACE WATER SUPPLY, 1955, PART 12

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,

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 

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

for each of the 14 parts. Beginning with the reports for 1951, the records are published 

in 18 volumes, there being 2 volumes each for Parts 1, 2, 3, and 6. The boundaries of the

The records at most of the stations discussed in these reports extend over many years. 

Discharge measurements at many points other than regular gaging stations have been made 

each year and are published 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.

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 reexamlned and 

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

practical.

Records of discharge have been published also In State reports. Most of these records 

are also compiled In Water-Supply Paper 1316; however some of them are not contained In 

the publications of the Geological Survey. The following table contains a list of these

HYDROLOGIC CONDITIONS

The water year 1955 was characterized by slightly above median runoff over most of the 

area covered by this report. Runoff was deficient over most of the area during March and 

April. During the remainder of the year runoff was near or slightly above median except 

during July when runoff was excessive. The excessive runoff during July came from delayed melting of the snow pack and heavy precipitation. No outstanding floods occurred 

during the year. For two key gaging stations in the area, a comparison of the monthly 

and yearly mean discharges during the 1955 water year with the median discharges for the

25-year period 1921-45 is shown in figure 3 below.

PUYALLUP RIVER BASIN 81

Mud Mountain Reservoir near Buckley, Wash.

Location. Lat 47°08'30" ) long 12l°55'50", In NE£ sec. 17, T. 19 N., R. 7 E., on left bank 

of reservoir just upstream from Mud Mountain Dam on White River, 5 miles southeast of 

Buckley and 6 miles downstream from Clearwater River.

Drainage area. 400 sq ml.

Records available. October 1943 to September 1955. Month-end contents only October 1943 

to September 1944, published in WSP 1316.

Gage.--Staff gage read once daily. Datum of gage is at mean sea level (levels by Corps 

of Engineers).

Extremes. Maximum contents observed during year, 21,500 acre-ft June 8 (elevation,

1,082.0 ft); minimum observed, 43 acre-ft on many days during October, November, December, and September (elevation, 908.0 ft).

1944-55: Maximum contents observed since dam was completed, 21,800 acre-ft June 8, 

1953 {elevation, 1,082.6 ft); no pool at times most years.

Remarks. Reservoir. for flood control, is formed by earth-fill dam. Embankment completed 

and storage began on small scale in 1942. Capacity, 106,000 acre-ft between elevations 

895 ft (invert of outlet tunnel) and 1,215 ft (spillway crest). Storage is not retained 

but is dissipated as soon after a flood as is possible without creating damaging flows 

downstream in order to have the maximum capacity available for any following flood which 

might develop.

Cooperation. Records of reservoir elevations and capacity table furnished by Corps of 

Engineers.

Capacity table (elevation, in feet, and contents, in acre-feet)

Records available. January 1945 to September 1955.

Gage. Water-stage recorder. Datum of gage is at mean sea level (Intercounty River Improvement Commission benchmark).

Average discharge. 10 years, 598 cfs (432,900 acre-ft per year).

Extremes. Maximum discharge during year, 7,380 cfs June 12 (elevation, 57.87 ft); minimum, 36 cfs Sept. 20, 21; minimum elevation, 51.54 ft Nov. 3.

1945-55: Maximum discharge, 13,100 cfs Dec. 14, 1946 (elevation, 59.74 ft); minimum, 32 cfs Nov. 29, 30, 1952; minimum elevation, 48.48 ft Feb. 1, 1945 (channel 

affected by dredging).

Remarks. Records good except those for periods of shifting control, which are fair, 'and 

those for periods of no gage-height record, which are poor. An average of 600 to 900 

cfs diverted from White River (head of Stuck River) above station into Lake Tapps for 

Dieringer powerplant of Puget Sound Power & Light Co. High flow influenced by regulation in Mud Mountain Reservoir (see p. 81). Records of suspended sediment loads 

for the water year 1955 are given in WSP 1403.

Revisions. WSP 1216: Drainage area.

Records available. October 1928 to September 1955. Prior to October 1951, published as 

"near Tolt."

Gage. Water-stage recorder. Datum of gage is at mean sea level, unadjusted. Prior to 

Bee. 20, 1933, chain or wire-weight gage on old bridge, 100 ft upstream at datum 

42.96 ft higher. Dec. 20, 1933, to Sept. 30, 1939, water-stage recorder at present 

site at datum 42.96 ft higher than present datum. Auxiliary water-stage recorder Is 

miles upstream from base gage.

Extremes.--Maximum discharge during year, 25,300 cfs Feb. 8 (elevation, 55.33 ft); minimum, 461 cfs Sept. 13 (elevation, 44.43 ft Sept. 13); minimum daily, 874 cfs Sept. 26.

1928-55: Maximum discharge, 59,500 cfs Feb. 27, 1932 (elevation, 59.88 ft, from 

graph based on gage readings); maximum elevation observed, 59.93 ft Nov. 13, 1932; 

minimum discharge, 239 cfs Aug. 21, 1945, but may have been less sometime during period 

of faulty intake action Sept. 13 or 14, 1949; minimum elevation recorded, 43.30 ft 

Sept. 11, 1930; minimum daily discharge, 396 cfs Sept. 24, 1938.

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

fair. Several small diversions for irrigation and domestic use above station. Low 

flow diverted for operation of powerplant at Snoqualmie Falls but returned to river 

above station. Some pondage at Snoqualmie Falls and some diurnal fluctuation caused 

by powerplant.

NOOKSACK RIVER BASIN 161

Fishtrap Creek at Lynden, Wash.

Location Lat 48°57'50", long 122°26'00", on north line sec. 16, T. 40 H., R. 3 E., on 

 FTinT'bank on downstream side of bridge on State Highway 1A, 1 mile north of Lynden.

Drainage area. 24.1 sq mi, of which 18.5 sq mi is in Canada.

Records available. July 1948 to September 1955.

Gage.. Water-stage recorder. Altitude of gage is 110 ft (from topographic map).

Average discharge.--? years, 36.2 cfs (26,210 acre-ft per year).

Extremes. Maximum discharge during year, 354 cfs Nov. 22 (gage height, 5.49 ft); minimum, 4.7 cfs Sept. 18-20, 22, 23 (gage height, 1.38 ft).

1948-55: Maximum discharge, 550 cfs Feb. 11, 1951 (gage height, 6.59 ft); minimum, 0.4 cfs Sept. 10, 1949 (gage height, 1.00 ftj.

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

Mb regulation. Probably some small diversions for minor irrigation and domestic use. 

It is improbable that any flow has bypassed the station during high stages during 

period of record. Statements in previous reports regarding overflow were erroneous.

Records available. May to October 1904, October 1927 to September 1955 (gage heights only, 

prior to March 1928}. Gage heights collected in this vicinity since 1904 are contained 

in reports of U. S. 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 since 

May 8, 1942. 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 _ .--..- 

three-quarters of a mile downstream at different datum. Oct?age on railroad bridge 

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. 27 years (1928-55), 14,530 cfs (10,520,000 acre-ft per year).

Extremes. Maximum discharge during year, 86,200 cfs June 15; maximum elevation, 1,774.80 

ft June 15; minimum discharge, 2,390 cfs Feb. 28, but may have been less during period 

of ice effect; minimum elevation, 1,742.12 ft Mar. 29.

1927-55: Maximum discharge, 139,000 cfs May 27, 1948 (affected by dike breakage 

downstream); maximum elevation, 1,778.55 ft May 21, 1954; minimum daily discharge. 

1,300 cfs Feb. 8, 1936; minimum elevation, 1,741.14 ft Dec. 5, 1929, Dec. 29, 1930, 

datum then in use.

Flood in 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, May 21 to July 22, 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. See Remarks for Kootenai River at Boom Camp on preceding 

page. No regulation or diversion above station.

1,767.93 ft June 27; minimum daily discharge, 2,600 cfs Feb. 28; minimum elevation 

1,740.34 ft Apr. 5.

-, ^2 ^55i Maxllnum daily discharge, 124,000 cfs May 30, 1948; maximum elevation, 

1,770.47 ft May 23, 1954; minimum daily discharge, 1,350 cfs Feb. 8, 1936; minimum 

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

Remarks. Records excellent except those for periods of ice effect or wind effect, which 

are good. Discharge and elevations affected slightly by flooding of small area (see 

Remarks for station at Boom Camp, p. 170). Stage-discharge relation affected by backwater from Kootenay Lake. 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.

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

United States under agreement with Canada.

KOOTENAI RIVER BASIN 181

Kootenai River at Porthill, Idaho 

(International gaging station)

Location. Lat 49°00'00", long 116°3o''10", in SW£ 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 1927 to-March 1928 (gage heights only), 

and April 1928 to September 1955 in reports of Geological Survey. October 1984 to 

September 1927 (gage heights only) in reports of Department of Northern Affairs and 

National Resources, Canada.

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

to benchmark 10-M-1928, at elevation 1,767.68 ft. Gage readings have been reduced 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.--27 years, 15,430 cfs (11,170,000 acre-ft per year).

Extremes. Maximum daily discharge during year, 88,700 cfs. June 15; maximum elevation, 

1,764.13 ft June 27; minimum daily discharge, 2,720 cfs Feb. 28; minimum elevation, 

1,740.09 ft Apr. 5.

1928-55* Maximum daily discharge, 125,000 cfs June 1, 1948; maximum elevation, 

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

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

Maximum elevation known, 1,722.7 ft in June 1894, present datum.

Remarks. Records excellent except those for periods of ice effect or wind effect at station" 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 U. S. 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 and 

p. by flooding 170). of small areas upstream (see Remarks for Kootenai River at Boom Camp, 

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

United States under agreement with Canada.

FEND OREILLE RIVER BASIN 219

Clark Fork at Whitehorse Rapids, near Cabinet, Idaho 

(Formerly published as Clark Fork near Heron, Mont.)

Location.-- Gage at lat 48°05 I 25", long 116°03'50", in NE£sw£ sec. 27, T. 55 N., R. 3 E., 

°n 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 Pork. Measuring cableway 0.4 

mile downstream. Discharge computed at Whitehorse Rapids, 2.7 miles downstream.

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

Records available . September 1928 to September 1955. Prior to October 1952, published 

as Clark Fork near Heron, Mont.

£6. Water-stage recorder. Datum of gage is 2,000.00 ft above mean sea level, datum of 

T929, supplementary adjustment of 1947, levels by Washington Water Power Co. Prior to 

Oct. 30, 1928, staff gage and Oct. 30, 1928. to Apr. 8, 1952, water-stage recorder, at 

site near Heron, 4 miles upstream at datum 88.00 ft higher prior to 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. 87 years, 20,670 cfs (14,960,000 acre-ft per year).

Extremes . i 952^53 : Maximum discharge during water year, 97,400 cfs June 16 (gage height 

85.10 ft); minimum, 884 cfs Apr. 18 (gage height, 64.48 ft); minimum daily, 1,140 cfs

1953-54: Maximum discharge during water year, 105.000 cfs May 22 (gage height, 

85.95 ft); minimum, 790 cfs Mar. 21 (gage height, 64.20 ft); minimum daily, 980 cfs 

Jan. 17.

1954-55; Maximum discharge during water year, 85,700 cfs June 18 (gage height,

, .

Remarks . Records excellent except those below about 5,000 cfs, which are good, and

those for periods of no gage-height record, which are fair. Flow regulated by Hungry 

Horse Reservoir (see p. 211) and Flathead Lake (see p. 215) . Extreme diurnal fluctuation caused by powerplant at Cabinet Gorge Dam. Diversions above station for irrigation of about 354,000 acres. Discharge measurements show that there is approximately 

1,000 cfs ground-water inflow between Cabinet Gorge Dam and Whitehorse Rapids, and it 

has been observed that approximately 600 cfs of this inflow occurs in the reach (2.3 

miles) from the measuring cableway to Whitehorse Rapids. Published records give flow 

at Whitehorse Rapids, computed by adding 600 cfs to observed flows at the measuring 

cableway, and are considered to be comparable to records at former site near Heron, 

except for surface flow from additional drainage area. To determine flow through the 

turbines and over the spillway at Cabinet Gorge Dam, 1,000 cfs should be deducted from 

flows published herein.

Cooperation. ~Q age-height record furnished by Washington Water Power Co. and 10 discharge 

measurements made by or in collaboration with that company.

Discharge measurement made on this day.
PEND OREILLE RIVER BASIN 229

Pend Oreille River below Z Canyon, near Metaline Palls, 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 Z Canyon, 1^ miles south of international 

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

Metaline Palls.

Drainage area.--25.200 sq mi, approximately.

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

September 1955. Prior to October 1928, published as Clark Pork at Metaline Palls 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 Palls 10 miles upstream at datum approximately 

262.2 ft higher.

Average discharge. 43 years (1912-55), 26,310 cfs (19,050,000 acre-ft per year).

Extremes. Maximum discharge during year, 88,900 cfs June 20 (gage height, 37.53 ft); 

minimum, 5,280 cfs Aug. 13 (gage height, 9.92 ft).

1912-55: 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 except those for period of no gage-height record, which are 

good. In 1946 there were diversions for irrigation of about 340,000 acres, and there 

probably has not been any appreciable change since that time. Plow regulated at 

Albeni Palls and Box Canyon Dams and affected by storage in Pend Oreille Lake (see 

p. 221), Plathead Lake (see p. 215), Hungry Horse Reservoir (see p. 211), and several 

smaller reservoirs (see p. 230).

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

States under agreement with Canada.

COLUMBIA RIVER MAIN STEM 231

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. --October 1937 to September 1955. Prior to March 1938 monthly, discharge only, published in WSP 1316.

Sage.--Water-stage recorder. Datum of gage is at mean sea level (Bureau of Reclamation 

T937 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. Jan. 1 to 

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

Average discharge.--18 years, 95,900 cfs (69,430,000 acre-ft per year).

Extremes.--Maximum discharge during year, 403,600 cfs June 29 (elevation, 1,328.37 ft); 

minimum, 26,800 cfs Mar. 5 (elevation, 1,291.33 ft).

1937-55: Maximum discharge, 550,100 cfs- June 12, 1948 (elevation, 1,338.13 ft); 

minimum, 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 were under irrigation in the United States in 1946. 

Water is diverted for the 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 other lakes and reservoirs in Kootenay and Pend 

Oreille River basins. Records of chemical analyses and water temperatures for the 

water year 1955 are given in WSP 1403.

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

United States under agreement with Canada.

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

929, supplementary adjustment of 1947, or 2,100 ft above mean sea level, datum of 

Geological Survey as given in Bulletin 567. Apr. 14, 1911, to Sept. 30, 1912, staff 

gage at site 2^ miles downstream at different datum. July 13 to Dec. 21, 1920, staff 

gage at present site and datum.

Average discharge.--36 years (1911-12, 1920-55), 2,287 cfs (1,656,000 acre-ft per year).

Extremes. Maximum discharge during year, 18,200 cfs May 21 (gage height, 88.30 ft); minimum recorded, 338 cfs Mar. 5 (gage height, 79.50 ft), but may have been less during 

period of ice effect.

1911-12, 1920-55: Maximum discharge, 53,000 cfs Dec. 23, 1933, computed on basis of 

slope between gages downstream; maximum gage height, 93.1 ft Apr. 18, 1938, from floodmark; minimum discharge, 91 cfs Nov. 27, 1952; minimum gage height, 78.43 ft Dec. 5,

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

of 1929, supplemental 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 daturas. Oct. 1, 1945, to 

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

Average discharge.--35 years (1920-55), 504 cfs (364,900 acre-ft per year).

Extremes. Maximum discharge during year, 3.300 cfs Apr. 22 (gage height, 4.78 ft); maximum gage height, 4.97 ft Feb. 9 (ice Jam); minimum daily discharge, 50 cfs Dec. 18, 19.

1911-12, 1920-55: 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 discharge, 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 diversion or appreciable regulation above station.

SANPOIL RIVER BASIN 263

Sanpoil River near Keller, Wash.

Location. La t 48°06'30", long 118°41'50", 

0.3 mile upstream from Brush Creek and

In SE£ sec. 7, T. 30 N., R. 33 E., on right bank 

£ miles north of Keller.

Drainage area. 890 sq ml, approximately.

Records available. August 1952 to September 1955 (discontinued).

. Water-stage recorder. Datum of gage is 1,464.08 ft above mean sea level, datum of 

929, supplementary adjustment of 1947.

Extremes . Maximum discharge during year, 1,120 cfs Apr. 23 (gage height, 6.39 ft); minimum, 32 cfs Sept. 13 (gage height, 3.72 ft).

1952-55: Maximum discharge, 2,210 cfs Apr. 29, 1953 (gage height, 8.08 ft); minimum, 

that of Sept. 13, 1955.

Maximum stage known, 10.02 ft, from high-water marks inside and outside of well, 

during high water in May 1956 after station had been discontinued.

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

which are poor. At high stage and during irrigation season, water is sometimes diverted 

into Kettle River basin through Curlew Lake and Creek. At extreme stages there may be 

some flow from Curlew Creek into Sanpoil River basin. No regulation.

266 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., in 

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 1955 (monthly discharge only, April 1913 to 

June 1923, January 1924 to May 1928). Published as "at Grand Coulee, near Nespelem" 

prior to 1936 and as "at Grand Coulee" 1936-42.

Gage. 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 datura 2.4 ft lower. Apr. 1, 1931, to Dec. 31, 

1935, water-stage recorder at site 850 ft downstream at present datura. Since June 12, 

1955, auxiliary water-stage recorder 6 miles downstream from base gage.

Average discharge. 42 years, 108,200 cfs (78,330,000 acre-ft per year), unadjusted.

Extremes. Maximum discharge during year, 414,100 cfs June 28 (elevation, 979.13 ft);

maximum elevation, 979.18 ft June 30; minimum discharge, 33,600 cfs Nov. 19 (elevation, 

936.60 ft).

1913-55: Maximum discharge, 637,800 cfs June 12, 1948 (elevation, 987.90 ft); 

minimum daily, 15,300 cfs Feb. 1, 1937.

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

Remarks. Records excellent. Feeder canal diverts water by pumping from Franklin D. 

Roosevelt Lake for Columbia Basin project (see preceding page). Other diversions 

above station for irrigation are a small percentage of flow past gage. Flow regulated 

by Franklin D. Roosevelt Lake (see p. 265) and reservoirs in Kootenai, Pend Oreille, 

and Spokane River basins. Records of chemical analyses and water temperatures for the 

water year 1955 are given in WSP 1403.

Methow River at Twisp, Wash.

Location. Lat 48°21'40", long 120°06'50", in NW£ sec. 17, 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 1955. 

published in WSP 1316.

Monthly discharge only for some periods,

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. 3, 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.--36 years, 1,287 cfs (931,700 acre-ft per year).

Extremes. Maximum discharge during year, 16,600 cfs June 12 (gage height, 8.22 ft in gage 

well, 8.90 ft from high-water mark on outside gage); minimum, 283 cfs Sept. 30 (gage 

height, 1.74 ft in gage well).

1919-29, 1933-55: 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 

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, which are fair. 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).

Revisions (water years). WSP 512: Drainage area. WSP 1316: 1921(M), 1928(M), 1934.

278 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., near right 

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

mile south of Chelan (revised).

Drainage area. 951 sq mi.

Records available.--November 1903 to September 1955. 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 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 500 to 1,000 ft below dam at same datum. 

Oct. I, 1927, to Nov. 10, 1928, staff gage, and Nov. 11, 1928, to Mar. 19, 1939, waterstage recorder, at sites 2|- miles downstream at same datum.

Average discharge (revised].--51 years (1904-55), 2,018 cfs (1,461,000 acre-ft per year), 

adjusted for storage since October 1911.

Extremes. Maximum daily discharge during year, 10,100 cfs July 14; minimum daily, 28 cfs 

May 5-8, 10.

1903-55: 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. Chelan County Public Utility District No. 1 diverts water 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. Prior to July 1, 1955, the 

diversion was by Washington Water Power Co. 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 Washington 

Water Power Co. to June 30 and by Public Utility District No. 1 of Chelan County thereelf tSI*

ENTIAT RIVER BASIN 279

Entiat River at Entiat, Wash.

Location. La t 47°39'40", long 120 "13 "30", in SE£ sec. 17, T. 25 N., R. 21 E., on right 

bank at Entiat and a quarter of a mile upstream from mouth.

Drainage area. 419 sq mi.

Records available. October 1910 to September 1925, June 1951 to September 1955.

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

T910 to Sept. 30, 1925, staff gage at site three-quarters of a mile upstream at different datum.

Average discharge. 19 years, 496 cfs (359,100 acre-ft per year), unadjusted.

Extremes. Maximum discharge during year, 4,800 cfs June 13 (gage height, 5.89 ft); minimum daily, 111 cfs Sept. 30.

1910-25, 1951-55: Maximum discharge, 5,380 cfs June 18, 1916 (gage height, 5.07 

ft, from graph based on gage readings); minimum observed, 32 cfs Jan. 30, 1923 (result 

of discharge measurement).

Maximum discharge known, 10,800 cfs May 29, 1948, on basis of conveyance-slope 

determination of peak flow.

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

which are poor. 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.

Revisions (water years). WSP 1286: 1916(M). WSP 1316: 1914-15(M), 1918(M).

Rating tables, water year 1954-55, except period of ice effect (gage

YAKIMA RIVER BASIN 303

Yakima River near Martin, Wash.

Location. Lat 47 0 19'10", long 121°20'10", in NE£ sec. 12, T. 21 N., R. 11 E., on left

bank 800 ft downstream from dam at outlet of Keechelus Lake, 3-5 miles northwest of

Martin, and 9-| miles northwest of Easton. 

Drainage area. 55.8 sq mi.

Records available.--October 1903 to September 1955. 

Gage. 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 datums. 

Average discharge. 52 years (1903-55), 329 cfs (238,200 acre-ft per year), adjusted for

storage since January 1906. 

Extremes. Maximum discharge during year, 1,300 cfs June 23; maximum gage height, 7.85

ft July 1, 2; minimum discharge, 1.4 cfs Oct. 30 to Nov. 2 (gage height, 2.13 ft). 

1903-55: 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. 319). Keechelus Lake

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

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

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

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

Teanaway River.

Drainage area. 500 sq mi, approximately.

Records available.--August 1906 to September 1955.

Gage.--Water-stage recorder. Datum of gage Is 1,902.27 ft above mean sea level (levels 

oy Bureau of Reclamation). 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.--49 years, 1,969 cfs (1,425,000 acre-ft per year), adjusted for storage since October 1906 and Klttitas Canal diversion since 1930.

Extremes.--Maximum discharge during year, 10,000 cfs June 12 (gage height, 10.68 ft); 

minimum, 131 cfs Nov. 12 (gage height, 5.19 ft).

Location. Lat 46°44'40", long 120°46'00", in SW^NE^ sec. 36, T. 15 N., R. 16 E. , on left 

bank half a mile downstream from Wapatox power canal, three-quarters of a mile downstream from Tieton River, and 3-| miles northwest of Naches.

Drainage area.--941 sq mi.

Records available. August to October 1905, October 1908 to September 1955. Monthly discharge only for some periods, published in WSP 1316.

Gage.--Water-stage recorder. Datum of gage is 1,549.67 ft above mean sea level, datum of 

1929, supplementary adjustment of 1947. Prior to Dec. 7, 1916, staff gage and Dec. 7, 

1916, to Sept. 9, 1936, water-stage recorder, at site five-eighths of a mile upstream 

at different daturas. Sept. 10 to Oct. 30, 1936, staff gage at present site and datum.

Average discharge. 47 years, 1,689 cfs (1,223,000 acre-ft per year), adjusted for diversions by Selah Valley and Tieton Canals since 1909, city of Yakima at Oak Flat since 

1929, by Wapatox Canal since 1936, for change in contents in Bumping Lake since November 1910, and in Tieton Reservoir since October 1924.

Extremes. Maximum discharge during year, 9,740 cfs June 12 (gage height, 16.63 ft); minimum, 8.5 cfs Mar. 6 (gage height, 9.81 ft).

1905, 1908-55: 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, which are poor. Flow regulated by Bumping Lake and Tieton Reservoir (see p. 319 ) , by diversion at Oak Flat 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 seven discharge measurements furnished by Bureau of Reclamation.

Revisions (water years). WSP 1216: Drainage area. WSP 1286: 1910(M) , 1911, 1929-30(M),

316 YAKIMA RIVER BASIN

Yaklma River near Parker, Wash.

, T. 12 N., R. 19 E., on left bank 

miles east of Parker, and 3 miles

Location.--Lat 46°29'40", long 120°26'10", in sec. 28 

700ft downstream from Sunnyside diversion dam, l| 

downstream from Ahtanum Creek. <

Drainage area. 3.650 sq mi, approximately.

Records available. April 1908 to September 1955. 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 benchmark). Prior to Jan. 1, 1909, hook gage at site 25 ft above headgate 

of Sunnyside 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, 18,400 cfs June 12 (gage height, 10.68 ft); minimum, 88 cfs Apr. 28 (gage height, 2.08 ft); minimum daily, 204 cfs Apr. 28.

1908-55: 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 excellent except those for periods of no gage-height record, which are 

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

220,000 acres below station. 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. 319).

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

which furnished 12 discharge measurements.

DISCHARGE MEASUREMENTS AT POINTS OTHER THAN GAGING STATIONS 323

Measurements of streamflow in the Pacific slope basins in Washington and upper Columbia 

River basin made at points other than regular gaging stations are given in the following 

table. Most of these measurements were made during periods of base flow when streamflow 

is primarily from ground-water storage. Measurements believed to have been made under 

base flow conditions are identified by an asterisk (*) to the left of the discharge 

figure. These measurements when correlated with the simultaneous discharge of a nearby 

stream where continuous records are available will give a picture of the low-flow potentiality of stream. The column headed "Measured previously shows the water years for which 

measurements were made at the same, or practically the same, uite.
