SCOPE OF WORK

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

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

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

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

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

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

points in the 1952 water year.

records of discharge prior to publication, and other unpublished data concerning the 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 years. 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 stage-discharge relation at the gage. This feature may be a natural constriction of the channel, 

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

Contents is the volume of water in a reservoir. Unless otherwise indicated, volume Is 

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

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

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

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

within the area unless otherwise noted.

DOWNSTREAM ORDER OF LISTING GAGING STATIONS

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

order of listing gaglng-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 date 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 

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

FIGURE 1. GAGING-STATION STRUCTURES
EXPLANATION OF DATA 5

tables gives the daily mean discharge, from which the monthly and the yearly mean discharge 

are computed. If the stage-discharge relation is subject to change because of frequent or 

continual change in the physical features that form the control, the daily mean discharge 

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

the gage heights to the rating tables. If the stage-discharge relation for a station is 

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

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

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

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

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

discharge. Information requisite for determining the slope or fall is obtained by means 

of an auxiliary gage set at some distance from the base gage. At some stations the stagedischarge relation is affected by changing stage. If so, the rate of change of stage is 

used as a factor in the determination of discharge.

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

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

the winter, and it becomes impossible to compute the discharge in the usual manner. Discharge for periods of ice effect is computed on the basis of the gage-height record and 

occasional winter discharge measurements, consideration being given to the available information on temperature and precipitation, notes by gage observers and engineers, and comparable records of discharge for other stations in the same or nearby basins. If the 

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

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

daily records is not changed.

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

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

runoff of the stream.

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

type and history of gages, average discharge, extremes of discharge, general remarks, 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 "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 daturas of previous gages for which discharge records are 

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

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

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

"Extremes" are given the maximum discharge and gage height; the minimum discharge if 

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). 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 non-
b SURFACE WATER SUPPLY, 1952, PART 13

recording gage read at the time of the crest. If the maximum gage height did not occur 

at the same time as the maximum discharge, It Is given separately. Information pertaining to the accuracy of the records and conditions which affect the natural flow at the 

gaging station Is given under "Remarks."

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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 dally mean discharge from a continuous gage-height graph and containing, as 

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

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

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

readings, or to the mean gaga 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 values for the maximum day and the minimum day for 

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

day of its occurrence.
ACCURACY OF FIELD DATA AND COMPUTED RESULTS 7

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

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

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

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

(line headed "In. 1 ), or in acre-feet (line headed "Ac-ft"). Values for cubic feet per 

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

large 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 values of maximum are the maximum 

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

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

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

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

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

the peaks are subject to substantial control by man.

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

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

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

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

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

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

a table showing daily contents or stage is given. A skeleton table of capacity at given 

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

but it is omitted from succeeding reports.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of streamflow data depends primarily on (1) the stability of the stagedischarge relation or, if the control is unstable, the frequency of discharge measurements, 

and (2) the accuracy of observations of stage, measurements of discharge, and interpretation of records.

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

more than 15 percent. 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, values of 

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

storage or diversion records are included to indicate the extent of the regulation or di-
8 SURFACE WATER SUPPLY, 1952, PART 13

version, 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 

various parts are indicated by the following list and the map in figure 2.

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

Miscellaneous measurements at many points other than regular gaging stations have been 

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

of each report. The streams and points of measurement are listed in the same order as 

the streams and gaging stations in the body of the report. An index of the records obtained before 1904 has been published in Water-Supply Paper 119.

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

883 for the Snake River basin) contains, for the area Included in that report, a summary 

of yearly discharge at gaging stations at which 10 or more complete years of record had 

been collected. These summaries were reprinted separately.

Reports also have been published that are compilations of records for various areas, 

usually a single State or drainage basin. These reports contain records previously published (some of which may have been revised), as well as some records not contained in 

the annual series of water-supply papers. The following table contains a list of these 

reports for the area covered by this report.

HYDROLOOIC CONDITIONS

The water year 1952 was characterized by well above normal runoff over most of the 

Snake River basin. Floods during April occurred in Owyhee, Malheur, Powder, and Grande 

Ronde River basins in Oregon, mostly as a result of snow melt. For two key gaging stations 

in the area covered by this report, a comparison of monthly and annual mean discharges 

(luring the 1952 water year with the median discharge for the 25-year period 1921-45 is

SNAKE RIVER MAIN STEM 25

Snake River near Heise, Idaho

Location.--Lat 43°37', long. 111°40', in sec. 5, T. 3 N., R. 41 E., on left bank about 

500 ft upstream from Anderson Canal headgate, 3 miles upstream from Heise, 6 miles east 

of Ririe, and 23 miles upstream from Henrys Pork.

Drainage area.--5,752 sq mi.

Records available. September 1910 to September 1952. Prior to 1911, published as South 

Fork Snake River near Heise.

Gage.--Water-stage recorder Altitude of gage is 5,015 ft (from river-profile survey). 

Prior to July 8, 1913, staff gage and July 9, 1913, to Sept. 29, 1922, water-stage recorder, at present site at datum 2.65 ft higher. Sept. 30, 1922, to Oct. 5, 1933, 

water-stage recorder at present site at datum 2.0 ft higher than present datum.

Average discharge.--42 years, 6,851 cfs.

Extremes.--Maximum discharge during year, 26,800 cfs June 8 (gage height, 8.27 ft); minimum, 2.600 cfs Dec. 18, 19.

1910-52: Maximum discharge, about 60,000 cfs May 19, 1927, result of washing out of 

landslide on Gros Ventre River (gage height, about 16.0 ft, present datum); minimum, 

1,210 cfs Jan. 22, 1935 (gage height, 1.15 ft).

Flood during early June 1894 probably as great as flood of May 19, 1927.

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

partly regulated by Jackson Lake (see p. ). Station is above all irrigation diversions 

from main river except Riley ditch (5,480 acre-ft diverted during year) which diverts 

1 mile upstream from station. About 106,000 acres in Wyoming and Idaho irrigated by 

diversions from tributaries above station.

Revisions. W 1217: Drainage area.

Rating table, water year 1951-52, except periods of Ice effect (gage

height, In feet, and discharge, In cubic feet per second)

Diversions from Snake River between Heise and Shelley gaging stations, Idaho

Between Heise and Shelley gaging stations, 47 canals divert water from Snake River for 

irrigation; of these 36 divert above mouth of Henrys Fork. Records available during each 

irrigation season from 1919 to 1952. One of the canals is equipped with a water-stage 

recorder the others with staff gages, which are read once daily. Discharge combined 

to show total diverted flow. Records include Riley ditch, which diverts 1 mile above «=-! Heise < «4.«4-.__ Records good. gaging station.

1930-52: Maximum daily discharge, 2,680 cfs July 26, 28, 1949; no flow for many 

days.

Remarks.--Records good. Gooding Canal diverts water from Snake River for Milner-Gooding 

project of Bureau of Reclamation and in part for project of North Side Canal Co. The 

latter project also receives water through the North Side Twin Falls Canal and P. A. 

lateral. Discharge of canal is computed by combining the discharge of Milner-Gooding 

diversion and that of North Side Canal Co. diversions below their division point and 

adding 35 cfs to that sum for loss between headgates and division point.

Cooperation. Gage-height record furnished by North Side Canal Co. and American Falls 

Reservoir District No. 2.

MUD LAKE-LOST RIVKR BASINS

Mud Lake near Terreton, Idaho

Location. Lat 43°53', long. 112°24', in SWij sec. 1, T. 6 N., R. 34 E. , 2 miles north of 

First Owsley pumphouse, 2-| miles northeast of Terreton, and 14 miles southwest of 

Hamer.

Drainage area. 1,050 sq mi, approximately, not including Medicine Lodge Creek (revised).

Records available.--April 1921 to September 1952.

Gage. Water-stage recorder. Datum of gage is 4,774.99 ft above mean sea level

("unadjusted). Prior to Oct. 31, 1931, staff gages at or near pumphouse (now used as 

supplementary gage) at same datum.

Extremes. Maximum contents during year, 44,100 acre-ft May 15, 16; maximum gage height, 

b.YV ft May 16 (affected by wind); minimum contents, 4,750 acre-ft Oct. 21; minimum 

gage height, 0.37 ft Oct. 29 (affected by wind).

1921-52: Maximum contents observed, 61,660 acre-ft May 5, 1923 (gage height, 9.20 

ft); practically no contents Oct. 1 to Nov. 15, 1937 (on Nov. 15, 1937, water was 

released from Camas Creek into lake).

Remarks. Mud Lake is a perched body of water confined by earth dikes and fed by ground 

water and surface tributaries augmented by well flows and surface inflow from North 

Lake. For complete description of Mud Lake region see Water-Supply Paper 818. Water 

for irrigation is diverted from lake by pumping. During low-lake stages inflow from 

Camas Creek may be bypassed through Camas Creek diversion canal directly to lake outlet channel leading to First Owsley pumping plant. Bypass was not used during 1952. 

Other irrigation diversions are made by various means from adjacent lakes and wells 

and Camas Creek above lake. Area of Mud Lake is varied from time to time by changes 

in dikes. Figures given herein represent contents above gage height -4.0 ft. Capacity table prepared from surveys made by Geological Survey and adjusted for changes in 

dikes. High winds occasionally disturb the recording of lake stages.

Cooperation. Water-stage recorder inspected by Water District No. 66 and supplemental 

staff-gage readings furnished by Owsley Canal Co.

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

which are fair, and those below 10 cfs, which are poor. Diversions above station for 

Irrigation. The sum of the combined discharge of east and west channels of Big Lost 

River and of the combined discharge of east and west channels of Warm Spring Creek, 

near Mackay, represents practically entire surface flow of Big Lost River which enters 

Mackay Reservoir (see p. 96).

Cooperation. Water-stage recorder graph and one discharge measurement furnished by Water 

District No. 27.

Location. Lat 43°58' , long. 113"45' , in NEjj sec. 5, T. 7 N., R. 23 E. , on right bank 500 

ft upstream from confluence with east channel and 1\ miles northwest of Mackay.

Records available. May 1919 to September 1952.

Gage. Water-stage recorder. Altitude of gage is 6,070 ft (from topographic map). Prior 

 to May 4, 1920, at datum 0.54 ft lower. May 4, 1920 to Dec. 2, 1938, at datum 0.4e ft 

higher.

Average discharge. 33 years, 93.2 cfs.

Extremes. Maximum discharge during year, 276 cfs June 7 (gage height, 2.89 ft); minimum, 

82 cfs Oct. 1, 2 (gage height, 1.43 ft),

1919-52: Maximum discharge, 600 cfs (estimated) Aug. 11, 1936 (gage height, 4.88 

ft, present datum, from floodmark); minimum, 49 cfs Apr. 27, 1935 (gage height, 1.08 

ft, present datum).

Remarks. Records good. Flow during summer represents return flow from Irrigation. The 

sum of the combined discharge of east and west channels of Warm Spring Creek and the 

combined discharge of east and *iest channels of Big Lost River, near Mackay, represents practically entire surface flow of Big Lost River which enters Mackay Reservoir 

(see following page).

o4T3TJ ft); minimum observed, 17,530 acre-ft Sept. 3 (gage height, 42.20 ft).

1919-52: Maximum contents observed, 42,390 acre-ft May 30, 1951 (gage height, 

65.04 ft); no available contents during periods in 1919, 1920, 1924, 1926, 1929, 

1931-35; minimum gage height observed, -3.3 ft Aug. 5, 1934.

Remarks. Reservoir is formed by earth and rock-fill dam, which was reconstructed in 

1317-18; storage impounded by original dam not recorded. Capacity is 38,400 acre-ft 

between gage heights 7.0 ft (bottom of outlet tunnel) and 62.0 ft (crest of spillway). 

Dead storage reported to be about 125 acre-ft. Water is used for irrigation of about 

33,000 acres in Big Lost River irrigation district. About 9,000 acres irrigated 

from Big Lost River and tributaries above reservoir. Considerable seepage around dam 

because of its porous foundation, but greater part of this water returns to Big Lost 

River between reservoir and station below reservoir, near Mackay. Figures given 

herein represent usable contents, computed for 12 p.m. on basis of once-daily readings of staff gage.

114 MALAD RIVER BASIN

Sliver Creek near Picabo, Idaho

Location. Lat 43°17', long. 114°01', In sec. 1, T. 2 S. ,^R. 20 E. , on left bank lj miles 

downstream from drain ditch of Blaine County Drainage District No. 1 and 3 miles southeast of Picabo.

Drainage area. 88 sq mi, approximately.

Records available. May 1920 to September 1952 (1922-35, irrigation seasons only). 

Gage.--Water-stage recorder. Altitude of gage Is 4,790 ft (by barometer). 

Average discharge.--19 years (1920-22, 1935-52), 153 cfs.

Extremes.--Maximum discharge during year, 317 cfs Apr. 15 (gage height, 3.70 ft); maximum 

gage height, 4.54 ft Jan. 5, 7 (ice jam); minimum discharge, 118 cfs Jan. 1, but may 

have been less during period of ice effect; minimum gage height, 1.48 ft May 28.

1920-52: Maximum discharge, that of Apr. 15, 1952; maximum gage height, 4.57 ft 

Jan. 22, 1950 (ice jam); minimum discharge, 26 cfs June 2, 1920 (gage height, 0.48 ft).

Remarks.--Records good except those for periods of Ice effect, which are poor. Diversions 

for irrigation of about 9,000 acres above station. Two small canals bypass station. 

Records of discharge do not include water bypassed around station at times by slough 

on right bank from which there is some diversion for irrigation. Silver Creek receives 

considerable return flow resulting from Big Wood River irrigation.

MALAD RIVER BASIN 115

Little Wood River near Richfield, Idaho

Location.--Lat 43°03', long. 114°08', in sec. 30, T. 4 S., R. 20 E. , on right bank half 

a mile upstream from Byrns Slough and heading of Dietrich Canal, 1 mile east of railroad station at Richfield, and 14 miles downstream from Silver Creek.

Drainage area. 570 sq mi.

Records available.--January 1911 to September 1952 (irrigation seasons only).

Gage.--Water-stage recorder. Altitude of gage is 4,270 ft (by barometer). Prior to 

Sept. 5, 1918, staff gage at present site at datum 1.00 ft lower. Sept. 5, 1918, to 

Apr. 13, 1920, staff gage at present site and datum.

Extremes.--Maximum discharge during year. 766 cfs May 5 (gage height, 3.58 ft); minimum 

recorded, 123 cfs Aug. 8; minimum gage height, 1.60 ft July 27, Aug. 8.

1911-52: Maximum discharge recorded, 868 cfs May 3, 1938 (gage height, 3.97 ft); 

minimum recorded, 7.6 cfs June 24, 25, 1920 (gage height, 0.52 ft).

Remarks. Records good. Diversions for irrigation of about 38,300 acres above station. 

Flow partly regulated by Little Wood Reservoir (capacity, 11,700 acre-ft), Fish Creek 

Reservoir (capacity, 13,700 acre-ft), and three small reservoirs on tributaries (combined capacity, 690 acre-ft). River above Silver Creek is dry a large part of the 

time because of channel losses and irrigation diversions above Carey.

Cooperation.--Water-stage recorder graph and four discharge measurements furnished by 

Water District No. 11 AB.

ft east of railroad station at King Hill and 20 miles downstream from Big Wood (Malad) 

River.

Drainage area.--35,800 sq mi, approximately. 

Records available . May 1909 to September 1952.

Mar. 7 to Aug. 16, 1910, staff gage three-quarters of a mile upstream at diff<

-Maximum discharge during year, 27,800 cfs May 10 (gage height, 12.06 ft); min- 

. served, 2,910 cfs Dec. 28 (gage height, 3.32 ft); minimum daily, 8,040 cfs 

July 10, 11, 18.

1909-52: Maximum discharge observed, 47,200 cfs June 22, 1918 (gage height, 16.3 

ft), from rating curve extended above 30,000 cfs; minimum observed, 1,250 cfs Jan. 10, 

1950 (gage height, 1.75 ft); minimum daily, 4,760 cfs July 7-9, Aug. 15, 16, 1910.

Remarks. Records excellent. Flow regulated by powerplants at Lower Salmon Palls and 

near Bliss and many reservoirs above station. Practically entire flow at Milner diverted during irrigation season; flow at King Hill is then derived largely from springs 

and seepage entering below Milner. About 1,590,000 acres of land irrigated by diversions from river and its tributaries above station. Records of chemical analyses and 

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

120 CANYON CREEK BASIN

Mountain Home feeder canal near Mountain Home, Idaho

Location. Lat 43°13', long. 115°42' , in sec. 36, T. 2 3. . R. 6 E. , on right bank 40 ft

 downstream from point of diversion from Canyon Creek and B miles north of Mountain 

Home.

Records available . April 1924 to September 1929, April 1931 to September 1952.

Gage.--Water-stage recorder and concrete control. Prior to May 4, 1924, staff gage and

 May 4, 1984, to Sept. 30, 1929, water-stage recorder, at site 30 ft downstream at 

datum 0.07 ft lower.

Extremes.--1924-29, 1931-52: Maximum daily discharge, 182 cfs Jan. 1, ]943; no flow at 

times during most years.

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

which are poor. Canal diverts from Canyon Creek in sec. 36, T. 2 S., R. 6 E., and 

delivers water to Mountain Home cooperative canal, which heads in Moantain Home feeder 

canal half a mile below station, for irrigation of about 5,000 acres in Mountain Home 

Irrigation District. During nonirrigation season and at times when there is a surplus 

of water for irrigation, canal feeds directly into Mountain Home Reservoir. Ho diversion from canal above station. Flow regulated by headgates in Canyon Creek and by 

Long Tom and Little Camas Reservoirs.

BOISE RIVER BASIN 145 

Diversions from Boise River between Bowling Rar ch and Boise gaging stations, Idaho

Between Dowling Ranch and Boise gaging stations, six principal canals and several 

small farm laterals divert water from Boise River for irrigation.

Records of total diversion during period April to September for each canal for years 

1919-46, combined daily diversion covering period April to September for years 1947-52, 

and daily flow of New York Canal February 1939 to October 1948 in reports of Geological 

Survey. Records of daily diversion for each canal from 1916 to 1952 on file in office 

of Idaho State Reclamation Engineer.

Records show summation of discharge for these diversions. Staff gages on canals read 

daily or several times weekly and discharge measurements made frequently. Field data 

obtained and records summarized under direction of E. B. Karn, watermaster for Boise 

River.

MALHEUR RIVER BASIN 155

Bully Creek near Vale, Oreg.

Location. Lat 43°58', long. 117°21', in SW-fc sec. 33 T. 18 S., R. 44 E., on right bank 

5 miles southwest of Vale.

Drainage area. 602 sq mi.

Records available.--Octobef1 1945 to September 1952 in reports of Geological Survey. April 

1&33 to May 1936 (fragmentary), March 1937 to September 1941 in reports of State engineer, and October 1941 to September 1945 in files of State engineer.

Gage. Water-stage recorder and concrete control. Altitude of gage is 2,317.7 ft (by 

levels to reference point furnished by Union Pacific R. R.). April 15, 1933, to May 

1936, water-stage recorder or staff gage at site 3 miles apstream at different datum. 

Mar. 15, 1937, to Jan. 1, 1940, water-stage recorder and concrete control at present 

site at datum 0.38 ft higher.

Average discharge. 16 years (1933-34; 1937-52), 40.9 cfs.

Extremes.--Maximum discharge during year, 2,890 cfs Mar. 26 (gage height, 6.98 ft), from 

rating curve extended above 1,200 cfs on basis of slope-area determination at gage 

height 6.55 ft; minimum, 6 cfs Dec. 7.

1933-52: Maximum discharge, 3,400 cfs Feb. 27, 1940,from rating curve extended above 

1,000 cfs; Maximum gage height, that of Mar. 26, 1952; no flow at times.

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

which are poor. Occasional fluetuations caused by releases from Vale-Oregon Canal which 

diverts water from irrigation of lands west of Vale, considerable return flow enters 

Bully Creek above station. Diversions above station for irrigation of about 7,000 acres.

Revisions (water years). W 1183: 1946, 1947.

Lake Fork Reservoir near McCall, Idaho

Location. La t 44°54', long. 116°03', in NW£NW£ sec. 13, T. 18 N., R. 3 E. , on Lake Fork 

Payette River and 3 miles east of McCall.

Drainage area. 64 sq mi, approximately.

Records available. April 1926 to September 1952.

Gage. Staff gage and graduations on concrete gate-control structure of dam; gage read 

once daily. Datum of gage is at mean sea level (levels by Lake Irrigation District).

Extremes. Maximum contents observed during year, 18,930 acre-ft July 6, 11, 12 (elevation,

 5,118.25 ft); practically no storage at times during fall and winter.

1926-52: Maximum contents observed, 19,740 acre-ft June 19, 1941 (elevation, 

5,118.75 ft); no storage above elevation 5,101.0 ft for long periods during fall and 

winter of most years.

Remarks. Reservoir is formed by earth and rock-fill dam completed in 1926. Capacity,

 16,940 acre-ft between elevations 5,101.0 ft (lower limit of capacity table, 4.0 ft 

above gate sill of outlet) and 5,117.0 ft (top of flashboards, 5.0 ft above spillway 

crest). Dead storage unknown. Water is used for irrigation of about 6,800 acres of 

land near McCall and Norwood. Figures given herein represent contents above 5,101.0 

ft. There is some usable storage be. ^w elevation 5,101.0 ft, but natural flow passing 

through reservoir when outlet gates are operating prevents withdrawal of storage to 

elevation of sill of gates. Storage figures from gage heights as observed.

Cooperation. Elevation record and capacity table furnished by Lake Irrigation District.

Sage.--Water-stage recorder. Altitude of gage is 770 ft (from comparison with gage

 Tf,300 ft upstream). Prior to Oct. 1, 1928, staff gage at site 2,300 ft upstream at 

datum 772.49 ft above mean sea level, datum of 1929, supplementary adjustment of 1947.

Average discharge. 26 years, 14,860 cfs.

Extremes.--Maximum discharge during year, 89,900 cfs Apr. 28 (gage height, 16.82 ft); min-

 imum, 1,940 cfs Sept. 29, 30 (gage height, 2.54 ft).

1926-52: Maximum discharge, 177,000 cfs May 29, 1948; maximum gage height, 25.6 ft 

Jan. 5, 1928 (present site and datum), from floodmark (ice jam); minimum discharge, 

probably less than 500 cfs Jan. 9, 1937, during period of ice effect.

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

 Small diversions from tributaries; slight diurnal fluctuation at times caused by 

powerplant on South Fork.

S48 SNAKE RIVER MAIN STEM

Snake River near Clarkston, Wash.

Location. Lat 46°25'30", long. 117°10'30", in lot 1, sec. 16, T. 11 N., R. 45 E., on 

right bank 2 miles upstream from Alpowa Creek, 7 miles downstream from Clarkston, and 

134 miles upstream fr&m mouth.

Drainage area. 103,200 sq mi, approximately.

Records available. October 1915 to September 1922 and August 1928 to September 1952 in 

reports of Geological Survey. October 1909 to September 1933 in State Water-Supply 

Bulletin 5. Prior to October 1935, published as at Riparia."

Gage. Water-stage recorder. Datum of gage is 670 ft above mean sea level (Corps of 

Engineers benchmark). Prior to Sept. 12, 1917, staff gage and Sept. 12, 1917, to 

Sept. 30, 1922, Aug. 6, 1928, to Sept. 30, 1935, chain gage, at site 66 miles downstream at different datum.

Extremes. Maximum discharge during year. 250,000 cfs Apr. 29 or 30 (gage height, 33.95 

ft, from high-water mark in gage well); minimum, 18,700 cfs Sept. 30 (gage height, 

10.52 ft); minimum daily, 20,700 cfs Aug. 27.

1909-52: Maximum discharge, 369,000 cfs May 29, 1948 (gage height, 40.36 ft, from 

high-water mark on gage well); minimum observed, 10,600 cfs Aug. 14, 18, 20, 24-28, 

30, 31, Sept. 1, 2, 5, 1931, but may have been less during period of ice effect in 

January 1937.

Maximum stage known, 24.7 ft, Riparia site and datum, June 5, 1894, determined 

from floodmarks by U, S. Weather Bureau (discharge, 409,000 cfs).

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

computed frcim graph based on telemark readings, which are good. Small diversions by 

pumping between this station and station at Oxbow, Oreg. Large diurnal fluctuation 

caused by powerplant on Clearwater River above Lewiston, Idaho. Records of chemical 

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