SCOPE OF WORK

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

water year ending September 30, 1958. 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 14,000 gaging stations in the 48 States and at many others in 

the Territories of Alaska and Hawaii. On September 30, 1958, the Geological Survey and 

cooperating organizations were maintaining 7,090 gaging stations, including those in 

Alaska and Hawaii. 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 water year October 1, 1957, to September 30, 1958, 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.

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records of discharge prior to publication, and other unpublished data concerning the 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

whioh 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 whioh gaging stations are on tributaries between any two stations on a main stem and the rank of the tributary on whioh 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, daps 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 has eight 

digits, but the station number as 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, 1958, PART 12

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

115. The notation in the two places 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 basis 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 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 

daily records is not changed.
EXPLANATION OP 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 1958 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 th"e 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 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

i 

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, --ach 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)" 

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
6 SURFACE WATER SUPPLY, 1968, 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 dally 

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

not indicate the true dally mean discharge, which must be obtained by averaging the discharge for parts of the day or by using the discharge integrator, an instrument for obtaining the 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 nonreoordlng gages, the table of dally 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. Discharge for the month may 

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

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

second per square mile and runoff in Inches are omitted if the drainage area Includes 

large noncontributlng 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 ioe 

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 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-sice 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 quallty-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 as "miscellaneous analyses" in quality-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 (E) 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 dally records is believed to be leas than 

6 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.

9 34 841 0*60-2
8 SURFACE WATER SUPPLY, 1958, 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 systemsPUBLICATIONS

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 

various parts are indicated by the following list and the map in figure 1.

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.
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 these special reports also contain other pertinent hydrologio information and analyses and compilations of data relating to earlier notable floods. The following is a list of these reports:

RECORDS OP 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 1957 to September 1958 by agencies other than the Geological Survey. The records of these stations 

are not contained in publications of the Geological Survey.

Note. Records of dally discharge for many canals and drains In Washington and Montana for 1956 

and earlier years have been collected by the Bureau of Reclamation and the Office of Indian Affairs 

of the United States Department df 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 mostly median or below during the 1958 water year, except during May 

when high runoff resulted from rapid snowmelt due to.high temperatures. Runoff was well 

below median in some areas and Chehalis River near Grand Mound, Wash, had the second lowest flow for August in 30 years of record. No noteworthy floods occurred during the water 

year. For two key gaging stations in the area covered by this report, a comparison of the 

monthly and yearly mean discharges during the 1958 water year with the median discharges 

for the 25-year period (1921-45) is shown in figure 2 on the following page. For Spokane 

River at Spokane, Wash., the discharges shown have been adjusted for storage.

980. Mud Mountain Reservoir near Buckley, Wash.

Location. La t 47°08 I 30", long 121°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 mi.

Records available. October 1943 to September 1958. 

to September 1944, published in WSP 1316.

Month-end contents only October 1943

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

Engineineers).

June 20,

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 (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 

neers.

LAKE WASHINGTON BASIN 111

1175. Cedar River near Landsburg, Wash.

Location. Lat 47°23'35", long 121°56'50", in NE£sw£ sec. 17, T. 22 N., R. 7 E. , on left 

bank 2 miles upstream from Landsburg and intake of Seattle water-supply system, 

% miles east of Maple Valley, 5 miles downstream from Taylor Creek, and 12 miles downstream from Cedar Lake.

Drainage area. 125 sq mi, excludes that of Rock Creek.

Records available. July 1895 to September 1958 (prior to October 1948, flow of Rock 

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

Published as "near Seattle" 1895-98, "near Msple 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. Mar. 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. 63 years, 688 cfs (498,100 acre-ft per year), unadjusted.

Extremes. Maximum discharge during year, 1,570 cfs Jan. 17 (gage height, 3.10 ft); minimum, 183 cfs Nov. 10; minimum gage height, 0.80 ft Sept. 30.

1895-98, 1901-58: 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 Cedar Lake; 

minimum observed, 83 cfs Sept. 19, 1898.

Remarks. Records excellent except those for periods of no gage-height record and shifting 

control, which are good. All diversions except Rock Creek returned to river above 

station. Rock 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 Cedar Lake.

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

Revisions (water years). WSP 313: 1895-98, 1902-9. WSP 1246: Drainage area. WSP 1S86-

182 KOOTENAI RIVER BASIN

3095. Kootenai River at Bonners Perry, Idaho

Location. Lat 48°42'00", long 116°18'45", in NE£ sec.27, T.62 N., R.I E., near right 

bank on downstream side of highway bridge at Bonners Ferry.

Drainage area. 13,000 sq mi, approximately.

Records available.--May to October 1904, October 1927 to September 1958 (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 bench mark V-3-1929 at elevation 1,777.08 ft. Gage readings have been 

reduced to elevations above mean sea level. Datum of 1929, supplementary adjustment 

of 1947, is 0.02 ft higher. May 1 to Oct. 15, 1904, staff gage on railroad bridge 

three-quarters of a mile downstream at different datum. Oct. 1, 1927, to Nov. 30, 

1929, staff gage near left bank. Dec. 1, 1929, to June 12, 1933, chain or wire-weight 

gages on old highway bridge 40 ft downstream. Datum of gages Oct. 1, 1927, to Jan. 2, 

1931, was about 0.23 ft lower.

Average discharge . 30 years (1928-58), 14,660 cfs (10,610,000 acre-ft per year).

Extremes. Maximum discharge during year, 74,600 cfs May 26; maximum elevation, 1,772.68ft 

May 26; minimum discharge, 2,420 cfs Jan. 4, but may have been less during period of 

ice effect; minimum elevation observed, 1,742.45 ft Mar. 19.

1927-58: Maximum discharge, 139,000 cfs May 27, 1948 (affected by dike breakage 

downstream); maximum elevati9n, 1,780.09 ft May 24, 1956; 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. Backwaller from Kootenay Lake usually present at Bonners Ferry. Discharge for periods of 

backwater at Boom Camp from Kootenay Lake, May 10 to June 18, 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. No drainage district dike failed during year.

Records available. October 1927 to September 1958 (gage-height record only prior to May 

1929). April 1925 to September 1927 (gage heights only) in reports of Department of 

Northern Affairs and National Resources, Canada.

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

To bench mark T-10-1914, elevation, 1 791.49 ft (datum of 1929, supplementary adjustment of 1947, is about 0.04 ft higher). Prior to Nov. 20, 1929, staff or recording 

gage at site three-quarters of a mile upstream; datum 40.77 ft higher prior to Apr. 18, 

1929 (revised). Gage readings have been reduced to elevations above mean sea level.

Average discharge. 29 years, 15,260 cfs (11,050,000 acre-ft per year).

Extremes.--Maximum daily discharge during year, 78,000 cfs May 25; maximum elevation, 

1,766.24 ft May 27; minimum daily discharge, 2,700 cfs Jan. 3; minimum elevation, 

1,740.91 ft Apr. 2, 3, 4.

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

Remarks. Records excellent except those for period of ice effect, which are good. Stagedischarge 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. No drainage district dike failed during year.

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

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

sites within 200 ft at different datums.

Average discharge. 28 years (1930-58), 63.0 cfs (45,600 acre-ft per year).

Extremes. Maximum daily discharge during year, 600 cfs May 23; minimum observed, 2.8 cfs 

Sept. 15, 16 (gage height, 3.09 ft).

1928-58: 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 possibly other days during 

period of no gage-height record in that year.

Remarks. Records fair except those for periods of ice effect or indefinite stagedischarge relation, which are poor. No regulation or diversion above station.

Revisions (water years). WSP 1316: 1939. WSP 1396: 1942.

192 KOOTENAI RIVER BASIN

3220. Kootenai River at Porthill, Idaho 

(International gaging station)

Location.--Lat 49°00'00", long 116°30'10", in SW-f 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 1958 in reports of Geological Survey. October 1924 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 

Tfo bench mark "10-M-1928", at elevation ",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. 30 years, 15,580 cfs (11,280,000 acre-ft per year).

Extremes. Maximum daily discharge during year, 81,100 cfs May 26; maximum elevation, 

1,762.28 ft May 27; minimum daily"discharge, 2,780 cfs Jan. 3; minimum elevation, 

1,740.35 ft Apr. 2, 3, 4.

1928-58: Maximum daily discharge, 125,000 cfs June 1, 1948; maximum elevation, 

1,767.53 ft June 5, 1956; minimum daily discharge, 1,380 cfs Feb. 8, 19S6; minimum 

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

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

Remarks. Records excellent except those for period of ice 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 is 

located. Elevations affected by backwater from Kootenay Lake. No drainage district 

dike failed during year.

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

238 PEND OREILLE RIVER BASIN

3920. Clark Pork at Whitehorse Rapids, near Cabinet, Idaho

Location. Lat 48°05'25", long 116°03'50", in NE&SW^ 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 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 1958. Prior to October 1952, published 

as Clark Pork near Heron, Mont.

ge. 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. 30 years, 21,000 cfs (15,207,000 acre-ft per year).

Extreme s.--Maximum discharge during year, 102,000 cfs May 26 (gage height, 85.60 ft); minimum, 830 cfs Aug. 11 (gage height, 63.84 ft); minimum daily, 2,110 cfs Sept. 1.

1928-58: Maximum discharge, 153,000 cfs May 29 to June 1, 1948; maximum gage height, 

50.97 ft May 31, 1948, site and datum then in use; minimum discharge observed, 270 cfs 

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

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

Maximum discharge known, 195,000 cfs June 1894 (elevation at point an eighth of a 

mile below "near Heron" site, 2,137.1 ft, from floodmark).

Remarks. Records excellent. Plow regulated by Hungry Horse Reservoir (see p. 228) and 

Flathead Lake (see p. 232). 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. Gage-height record furnished by Washington Water Power Co. and five discharge measurements made by employees of that company.

Revisions (water years ). WSP 1182: 1936.

FEND OREILLE RIVER BASIN 247

3985. Fend 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, If 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 1958. 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 

T929, 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. 46 years (1912-58), 26,530 ofs (19,210,000 acre-ft per year).

Extremes.--Maximum discharge during year, 99,300 cfs May 29 (gage height, 40.94 ft); minimum, 4,880 cfs Sept. 30 (gage height, 9.68ft); minimum daily, 5,530 cfs Sept. 1.

1912-58: 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 since that time. 

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

Oreille Lake, Flathead Lake, Hungry Horse Reservoir, and by 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 249

3995. Columbia River at international boundary 

(International gaging station)

Location.--Lat 49°00'03", long 117 e 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 1958. prior to March 1938 monthly discharge 

only, published in WSP 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 gage. Jan. 1 to 

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

Average discharge.--21 years, 96,830 cfs (70,100,000 acre-ft per year).

Extremes. Maximum discharge during year, 370,500 cfs May 30 (elevation, 1,326.75 ft); 

minimum, 20,800 cfs Jan. 14 (elevation, 1,290.06 ft).

1937-58: 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 of 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 except those for period of no auxiliary gage-height record, 

which are good. 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 1958 

are given in WSP 1574.

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

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

Extremes. Maximum discharge during year, 22,000 cfs May 23 (gage height, 13.52 ft); minimum, 222 cfs Jan. 1 (gage height, 2.59 ft), but may have been less during period of ice 

effect Dec. 30 to Jan. 2.

1929-58: Maximum discharge, 35,000 cfs May 29, 1948 (gage height, 17.25 ft); 

minimum, 88 cfs Dec. 1, 1936 (gage height, 2.20 ft), but was probably less during 

winter of 1929-30.

Maximum stage known, about 22 ft in May or June 1894, from information by local 

residents.

Remarks.--Records good prior to Mar. 1, excellent thereafter, except those for periods of 

ice effect, which are poor. North Pork regulated by reservoir at Grand Forks, British 

Columbia. Numerous diversions for irrigation of about 720 acres in the United States 

(for 1946 from United States reports) and 2,090 acres in Canada from the Canada Year

SPOKANE RIVER BASIN 267

4170. Hayden Lake at Hayden Lake, Idaho

Location.--Lat 47°46', long 116°45', in sec. 18, T. 51 N., R. 3 W., at Avondale and

Hayden Lake pumping plants, a quarter of a mile north of Bozanta Tavern at Hayden Lake.

Records available. May 1920 to September 1958.

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

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

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

Extremes. Maximum gage height observed during year, 40.52 ft Apr. 25-27; minimum observed, 

33.73 ft Nov. 10.

1920-58: Maximum gage height observed, 42.46 ft Apr. 22, 1956; minimum observed, 

19.38 ft Dec. 16, 1931.

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 Rathdrum Prairie. Some surface flow left the lake during high stages through a controlled 

outlet in the dike at southwest corner of lake. Estimated flow at outlet was 22 cfs 

on May 22. This water seeps rapidly into the ground in an extremely permeable area 

adjacent to the outlet.

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

Roosevelt Lake for Columbia Basin project (see p. 283). Other diversions above station for irrigation are a small percentage of flow past gage. Flow regulated by 

Franklin D. Roosevelt Lake (see preceding page) and reservoirs in Kootenai, Fend 

Oreille , and Spokane River basins. Records of chemical analyses and suspended sediment loads for the water year 1958 are given in WSP 1574.

4495. Methow River at Twisp, Wash.

Location. Lat 48 0 21'40", long 120 0 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 1958. Monthly discharge only for some periods, 

published In WSP 1316.

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

ro 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. 39 years, 1,318 cfs (954,200 acre-ft per year).

Extremes. Maximum discharge during year, 15,900 cfs May 25 (gage height, 8.29 ft); minimum, 202 cfs Sept. 1, 2 (gage height, 1.35 ft).

1919-29, 1933-58: 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 Jaeen less during period of ice effect Jan. 6 to Mar. 4, 

1937.

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

which are fair. A large part of 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 ^316: 1921(M) , 1928(M), 1934.

of a mile south of Chelan.

Record^avaffable. November 1903 to September 1958. Published as "below Chelan Lake"

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

4^2 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 Mar. 19, 

1939 water-stage recorder at sites 2| miles downstream at same datum. J4 t .,

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 percen-

 tage" 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. 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 0.5 mile east of Goose Lake, 2-jj- miles downstream from O'Sullivan Dam, 5 miles 

northwest of Othello, and 12 miles south of Warden.

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

probably noneontributing.

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 

1958. Published as Lower Crab Creek near Warden 1909-12. Records for September 1952 

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

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 daturas. 

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, 392 cfs May 24 (gage height, 4.45 ft), caused 

by partial failure of Fish and Wildlife Service Dam J mile upstream, from rating curve 

extended above 72 cfs; minimum, 3 .'6 cfs Jan. 6 (gage height, 0.57 ft); minimum daily, 

11.5 cfs Mar. 4.

1909-12, 1942-52, 1955-58: 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 

O'Sullivan Dam.

Remarks. Records fair. Many diversions for irrigation. Flow regulated by Potholes Reservoir and partially by Fish and Wildlife Service Dam since January 1958. Storage 

began in Potholes Reservoir above O'Sullivan Dam in September 1952. Discharge between 

then and September 1955 consisted of a small part of dam seepage. Discharge at present 

location includes essentially all of the seepage.

YAKIMA RIVER BASIN

R. 11 E., on left 

miles northwest of

4745. Yakima River near Martin, Wash.

Location.--Lat 47°19'10", long 121°20'10", in NE£ sec. 12, T. 21 N.

bank 800 ft downstream from dam at outlet of Keeehelus Lake, 3? r

Martin, and 9j miles northwest of Easton. 

Drainage area. 55.8 sq mi.

Records available.--October 1903 to September 1958. 

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 datums. 

Average discharge. 55 years, 330 cfs (238,900 acre-ft per year), adjusted for storage

since January 1906.

Extremes. Maximum discharge during year, 998 cfs July 27 (gage height, 7.61 ft); minimum, 1.4 cfs Oct. 28 (gage height, 2.07, ft).

1903-58: Maximum discharge, 7,370 cfs Mar. 26, 1915, when temporary crib dam was

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

Remarks.--Records good. Plow regulated by Keeehelus Lake (see p. 344). Keeehelus 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, 14 discharge measurements, and computations of daily

discharge furnished by Bureau of Reclamation; 2 discharge measurements made and

records reviewed by Geological Survey. 

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

700 ft downstream from Sunnyside diversion dam, lj miles east of Parker, and 3 miles 

downstream from Ahtanum Creek.

Eralnage area. 3,650 sq mi, approximately.

Records available. April 1908 to September 1958. Monthly discharge only for some periods, 

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

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

Reclamation bench mark). 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, 9,210 cfs Feb. 25 (gage height, 8.23 ft); minimum, 30 cfs June 18 (gage height, 1.84 ft); minimum daily. 49 cfs July 10.

1908-58: 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 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. 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. 344).

Cooperation. Gage-height record collected in cooperation with, and 20 discharge measurements furnished by Bureau of Reclamation.

DISCHARGE AT PARTIAL-'RECORD STATIONS AND MISCELLANEOUS SITES 347

As the number of streams on whicn 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 over a period of years 

for use in hydrologic analyses, the site at which the data are collected is called a 

partial-record station. Data collected at these partial-record stations are usable in 

low-flow or flood-flow analyses, depending on the type of data collected. In addition, 

discharge measurements are made at other sites not included in the partial-record program. 

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 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 made at miscellaneous sites for both low flow and high flow are given in a third 

table.

Low-flow partial-record stations

Measurements of streamflow in the area covered by this report made at low-flow, partialrecord 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. These 

measurements, when correlated with ^he simultaneous discharge of a nearby stream where continuous records are available, will give a picture of the low-flow potentiality of stream. 

The columm headed "Period of record" shows'the water years in which measurements were made 

at the same, or practically the same, site.

348 DISCHARGE AT PARTIAL-RECORD STATIONS AND MISCELLANEOUS SITES

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 flow 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. The maximum discharge for 

each year since the crest-stage gage was established is given. The peak discharge for 

some years may have been published in a previous report as a measurement of discharge. 

Figures given herein supersede all previous figures of peak discharge for the floods 

listed.
