SURFACE WATER SUPPLY OF SNAKE RIVER BASIN, 1946

SCOPE OF WORK

This volume is one of a series of 14 reports presenting results of measurements of 

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

water year ending September 30, 1946. The work was begun in 1888 in connection with 

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

stage and contents of lakes and reservoirs have been made at about 10,900 gaging stations 

in ttie 48 States and also at many in the Territories of Alaska and Hawaii. In July 1946, 

5,810 gaging stations, including those in Hawaii, were being maintained by the Geological 

Survey and cooperating organizations. Miscellaneous discharge measurements were imde 

during the water year at many other points.

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

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

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

volume, the section on cooperation of the second kind appears on page 12.

DEFINITION OF TERMS

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

herein are defined as follows:

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

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

whose average velocity is 1 fcot per second.

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

second from each square mile of area drained, on the assumption that the runoff is distributed uniformly both as regards time and area.

"Runoff in inches" is the depth to which an area would be covered if all the v/ater 

draining from it in a given period were uniformly distributed on its surface. It is used 

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

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

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

with storage for irrigation.

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

hours. It is equivalent to 86,400 cubic feet, 1.983471 acre-feet, or 646,317 gallons and 

represents a runoff of 0.0372 inch from 1 square mile.

"Stage-discharge relation" Is an abbreviation for the term "relation between ga?e height 

and discharge."

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

the stage^flischarge relation at the gage. This feature may be a natural section, a reach 

of the channel, or an artificial structure.

1
2 SURFACE WATER SUPPLY, 1946, PART 13

"Contents" Is a term applied to the volume of water In a reservoir. It is computed on 

basis of a level pool and does not include bank storage unless otherwise indicated.

EXPLANATION OF DATA

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

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

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

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

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

discharge. Typical structures In use at gaging stations are shown In figure 1.

Rating tables giving the discharge for any stage are prepared from the discharge measurements. The application of the daily mean gage height to those ratlig tables gives the 

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

If the stage-discharge relation is subject to change because of frequeit 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 fay engineers and observers are us?d In applying Hie 

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

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

For such times the dally mean discharge is computed by what Is essentially the "shiftingcontrol" method, described above.

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

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

method," in which the slope or fall in a reach of the stream Is a factor In the determination of discharge. Information requisite for determining Hie slope or fall Is obtained 

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

the stage-discharge relation Is affected by changing stage, and for t'tem 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 ttie United States and at some in the 

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

the winter, which makes It impossible to compute the discharge in the usual manner. Discharge for periods of ice effect is cotoputed 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 an1 engineers, and 

comparable records of discharge for stations in the same or nearby basins. For those 

stations at which the stage-discharge relation Is affected by ice, the days included In 

the periods-of Ice effect either are Indicated in the table by symbols referring to a 

footnote that states this fact or are given in a general note following the table. The 

days on which discharge measurements were made during or between periods of ice effect, 

shortly before the first period, or shortly after the last period are similarly indicated 

by a footnote.

For most of the gaging stations on streams in the area covered by tMs report the data 

presented comprise a description of tWe station, a table showing the d"».ily discharge of 

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

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

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

.or other special methods.

The description of the station gives the type of gage, its latitude and longitude as 

determined from the best available maps, and information in regard to diversions that 

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

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

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

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

the minimum discharge if there 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 or a nonrecording gage read at the time of the crest. Likewise the minimum discharge represents the 

lowest stage, unless otherwise qualified. Selected peak discharges with the times of 

their occurrence are given, below the table of monthly discharge, for some stations.' This 

supplementary information is generally omitted for a station at which the drainage area of 

the stream is less than 10 or more than 10,000 square miles or at which, on most days, the 

peak discharge exceeds the mean discharge by less than 10 percent.

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

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

gage height. For stations subject to such fluctuation the daily mean gage height may not 

indicate the true daily mean discharge, which must be obtained by averaging the discharge 

for parts of the day or by using the discharge integrator, an instrument for obtaining the 

daily mean discharge'from a continuous gage-height graph and containing as an essential 

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

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

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

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

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

stated In the station description.

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

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

"Maximum" gives the maximum daily discharge, not the momentary discharge when the water 

surface was at crest stage. Likewise,] in the column headed "Minimum" the quantity given 

is the minimum daily discharge. The column headed "Mean" gives the average flow in cubic 

feet per second during the month.

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

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

usually given in the first report in which data for a station are published but is omitted 

from succeeding reports.
SURFACE WATER SUPPLY, 1946, PART 13 5

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

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

and (2) the accuracy of observations of stage, measurements of flow, and interpretation of 

records.

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

records. "Excellent" indicates that, in general, the error in the daily records is 

believed to be less than 5 percent; "good," less than 10 percent; "fair," less than 15 percent; and "poor," probably more than 15 percent. The records of monthly and yearly mean 

discharge and runoff are, in general, more accurate than the daily records.

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

owing to diversion, consumption, regulation by storage, increase or decrease in evaporation 

due to artificial causes, or other factors. For such stations figures of "second-feet per 

square mile" and "runoff in inches" are not published unless storage or diversion records 

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

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

to use and control. Evaporation from a reservoir is not Included in the adjustments for 

changes in reservoir contents, unless its inclusion is indicated. Figures of second-feet 

per square mile and runoff in inches are also omitted if the drainage area includes large 

noncontributing areas or if the average annual rainfall over the drainage area is less 

than 20 inches.

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

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

below the station must first be satisfied.

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

station. The table of daily discharge affords opportunity for uore detailed studies of the 

variation in flow. As further observations in each succeeding year may be expected to 

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

subject to revision in succeeding water-supply papers.

PUBLICATIONS

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

and drainage basins, are listed by number on page 8. The data for any particular gaging 

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

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

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

453, 473, and 503, which contain records for the Ohio River Basin for those years.

The records at most of the stations discussed In these reports extend over a series of

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

' N 9en made each year and are published under "Miscellaneous discharge measurements" at the

 ^nd of each report, the streams and points of measurement listed appearing In the sa-ne

 elatlve order as the streams and gaging stations in the body of the report. An lnd?x of 

" *ie records obtained prior to 1904 has been published In Water-Supply Paper 119.

Each of the reports on surface water supply for the year 1939, Issued as Water-Supply

 >\pers 871 to 884 (see table on p. s), contains, for the area covered by that report, a

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

 -ecord have been collected. These summaries are available also as separate reprints.

Mote.- Of the records for the stations operated by the Oregon State engineer, those for 1925-30 

are published in Bulletin 8 of the State engineer, and those for 1931-36 (includ'.ng some to December 

1936) In Bulletin 9; those for 1937-46 have not been published.

Records for the stations operated by Idaho Water District 36 are published in the annual reports 

of that organization.

The Soil Conservation Service of the United States Department of Agriculture b<?gan in 1932 to 

collect records of runoff from one area of aftout 760 acres and three areas of le^s than 70 acres 

each near Pullman, Wash. The records are in the files of the Soil Conservation Service.

14 QAGING-STATION RECORDS

SNAKE RIVER MAIN STEM 

Jackson Lake at Moran, Wyo.

Location - Electric tape gage, lat. 43"51', long. 110-35', in sec. 18, T. 45 N., R. 114 

w., at dam on Snake River, at Moran. Datum of gage is at mean sea level (levels by 

Bureau of Reclamation).

Drainage area.- 816 square miles.

Records available.- July 1908 to September 1946 (1908-10 fragmentary).

Extremes.- Maximum contents during year, 852,870 acre-feet June 23-24 (elevation, 6,769.23 

feet); minimum, 397,600 acre-feet Sept. 21-22 (elevation, 6,750.21 feet).

1908-46: Maximum contents, 857,220 acre-feet June 23, 1937 (elevation, 6,769.40 

feet); no usable contents on several days during period August to Octoter 1919 (elevation, 6,730.00 feet).

Remarks^- Reservoir was formed by log crib dam in 1906 with a usable capacity of 300,000 

acre-feet. The dam washed out in July 1910 and was replaced by an earth dam, forming 

a reservoir with a usable capacity of 380,000 acre-feet. The earth dair was raised in 

1916 increasing the usable capacity to 790,000 acre-feet. In 1917, by dredging the 

outlet, the capacity was further increased to 847,000 acre-feet betweer elevations 

6,730 feet (top of baffles to sluices) and 6,769 feet (top of spillway gates). Water 

is used for irrigation in Snake River Valley, Idaho. Gage read once dsily at 8 a.m. 

Contents as given herein are computed from elevation at that time; all available for 

release.

Cooperation.- Reservoir elevations and capacity table furnished by Bureau of Reclamation.

reet); minimum, 1,770 second-feet Dec. 20 (gage height, 1.60 feet).

1910-46: Maximum discharge, about 60,000 second-feet May 19, 1927, result of 

washing out of landslide on Gros Ventre River (gage height, about 16.0 feet, present 

datum); minimum, 1,210 second-feet Jan. 22, 1935 (gage height, 1.15 feet).

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

Station is above all irrigation diversions from main river except Riley ditch (4,200 

acre-feet diverted during year), which diverts 1 mile upstream from station. About 

130,000 acres in Wyoming and Idaho irrigated by diversions from tributaries above 

station. Some regulation by Jackson Lake (see p. 14).

Island Park Reservoir near Island Park, Idaho

Location.- Electric tape gage, lat. 44"25', long. 111°24', in gatehouse shaft at dam on 

Henrys Pork, a quarter of a mile south of quarter corner between sees. 28 and 29, T. 

13 N., R. 43 E., a quarter of a mile upstream from Buffalo River, and 2 miles west of 

Island Park post office. Datum of gage is at mean sea level (levels by Bureau of 

Reclamation).

Drainage area.- 478 square miles.

Records available.- November 1938 to September 1946.

Extremes.- Maximum contents during year, 136,340 acre-feet May 29 (elevation, 6,303.14 

reetj; minimum, 51,385 acre-feet Sept. 19 (elevation, 6,289.15 feet).

1938-46: Maximum contents, 137,805 acre-feet June 8, 1945 (elevation, 6,303.32 

feet); minimum after first filling of reservoir in May 1939, 16,855 acre-feet Sept. 27, 

1940 (elevation, 6,274.22 feet).

Remarks.- Reservoir is formed by earth-fill, rock-faced dam. Storage began Nov. 15, 1938. 

 capacity, 127,265 acre-feet between elevations 6,239 feet (normal low-water level with 

outlet gates open) and 6,302 feet (crest of spillway). Natural flow passing through 

reservoir when outlet gates are open prevents withdrawal of storage to elevation 6,230 

feet (sill of lower outlet). Dead storage negligible. Water is used for irrigation of 

lands in Premont-Madlson irrigation district between Ashton, and Rexburg, Idaho. Gage 

read daily at 8 a.m. Contents given herein are computed from elevations at that time; 

all available for release.

flooding Canal at Milner, Idaho

Location (revised).- Water-stage recorder on Milner-Gooding Canal in NW-r sec. 18, staff

 gage in diversion canal in sec. 19, T. 10 S., R. 21 E., and differential recorder on 

control gates of North Side Canal Co. diversion in NE£ sec. 13, T. 10 S., R. 20 E., 

about 3 miles downstream from head gates that are in sec. 28, T. 10 S., R. 21 E., 

lat. 42°31', long. 114 0 01'.

Records available.- May 1930 to September 1946.

Extremes.- Maximum daily discharge during year, 2,480 second-feet July 31; no flow on 

many days.

1930-46: Maximum daily discharge, 2,580 second-feet July 31, Aug. 1, 2, 1942, 

July 31, Aug. 1, 3, 4, 1943; no floW on 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 Palls 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 from 20 to 60 second-feet to that sum for loss between head gates and division 

point.

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

Reservoir District No. 2.

Correction.- In Water-Supply Paper 1013 for the water year 1944 the figures shown in the

 two columns under "Distribution (acre-feet)" are reversed. The figures shown for 

Milner-Gooding project were for the North SMe Canal Co. project and vice versa.

82 TRIBUTARIES AND DIVERSIONS BETWEEN PORTNEUP RIVER AND SALMON PALLS CREEK

South Side Twin Falls Canal at Milner, Idaho

Location.- Water-stage recorder, lat. 42°31', long. 114°01', in sec. 29, T. 10 S., R. 21 

E., YUO feet downstream from head gates at Milner Dam.

Records available.- May 1909 to September 1946.

Extremes.- Maximum discharge during year, 3,620 second-feet July 25 {gage height, 10.39 

reet); minimum, 60 second-feet (estimated) on several days.

1909-46: Maximum daily discharge, 4,600 second-feet Aug. 12, 1918, computed on 

basis of stage-discharge relation for canal plus estimates by hydrographer of water 

wasted through spillway below station and returned to river; no flow Sept. 20, 1920.

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

rair. Flow controlled by head gates. Canal has diverted water since March 1905 from 

Snake River at Milner Dam for irrigation of 202,000 acres of land in Twin Palls County.

Cooperation.- Gage-height record furnished by Twin Falls Canal Co.

Discharge, in second-feet, water year October 1945 to September 1946

Average discharge.- 24 years, 211 second-feet.

Extremes.- Maximum discharge during year, 363 second-feet Sept. 3 (gag? height, 2.86 

reet); minimum, 117 second-feet Feb. 12 (gage height, 1.80 feet).

1922-46: Maximum discharge, 984 second-feet Sept. 21, 1927 (gag? height, 4.5 feet, 

datum then in use. from floodmarks); minimum, 90 second-feet Mar. 2?, 1941 (gage 

height, 1.66 feet).

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

Practically all normal summer flow diverted several miles above station for irri-

§

ation. Waste water from South Side Twin Palls low-line canal, which crosses Rock 

reek 12 miles above station, causes abrupt fluctuations in stage at times. Irrigation waste water and return flow from project lands enter above station.

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

water and surface tributaries. For complete description of Mud Lake region see WaterSupply Paper No. 818. Water for irrigation Is diverted from lake end tributaries by 

pumping and gravity. During 1946 season diversion dam in Camas Creek diversion canal 

was not in place. Area of lake is varied from time to time by charges in dikes. High 

winds occasionally disturb the recording of lake stages. Figures given herein represent contents above gage height -4.0 feet. Capacity table prepared1 from surveys made 

by Geological Survey adjusted for changes in dikes.

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

starr-gage readings furnished by Owsley Canal Co.

100 BIG LOST RIVER BASIN

Big Lost River (east channel) above Mackay Reservoir, near Mackay, Idaho

Location.- Water-stage recorder and concrete control, lat. 43°59', long. 113°45', In sec. 

32, T. 8 N., R. 23 E., above flow line of reservoir, 3 miles upstream from Mackay Dam 

and 1\ miles northwest of Mackay.

Records available.- May 1919 to September 1946. 

Average discharge.- 27 years, 63.1 second-feet.

Extremes.- Maximum discharge during year, 716 second-feet June 6 (gage height, 4.42 feet); 

minimum, 4 second-feet Feb. 17-21; minimum gage height, 1.14 feet FeX 18, 19

1919-46: Maximum discharge, 1,320 second-feet June 7, 1938; maximum gage height, 

5.02 feet July 1, 1944; no flow during long periods In 1920, 1923-38, 1940.

Remarks.- Records good except those below 10 second-feet and those for periods of no 

gage-height record, Ice effect, or backwater from reservoir, all of which are fair. 

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.

Cooperation.- Water-stage recorder graph furnished by Water District No. 27.

flow of Big Wood River and Big Wood Slough at Hailey.
116 BIG WOOD RIVER BASIN

Big Wood Slough at Haily, Idaho

Location.- Water-stage recorder, lat..43°31'00", long. 114°19'30", in sec. 9, T. 2 N.,

 RTTB~E., at highway bridge, an eighth of a mile northeast of steel highway bridge 

over Big Wood River and an eighth of a mile southwest of Hailey.

Records available.- June 1915 to September 1946. 

Average discharge.- 31 years, 117 second-feet.

Extremes (regulated).- Maximum discharge during year, 170 second-feet Apr. 12; maximum

 gage height, 3.1V feet Dec. 19 (ice jam); minimum discharge, 14 second-feet Aug. 22 

(gage height, 1.48 feet).

1915-46: Maximum discharge observed, 419 second-feet June 6, 1921, from rating 

curve extended above 280 second-fe$t; .maximum gage height, 5.55 feet (top of ice in 

well) Jan. 20-23, 1937; no flow May 8, 1931, Oct. 20 to Nov. 3, 1938.

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

 which are fair. Flow controlled at inoperative power plant, half a mile upstream, to 

meet the requirements of irrigation diversion from slough and sewage dilution. Big 

Wood Slough is a natural channel of Big Wood River and its discharge plus the discharge 

of Big Wood River at Hailey (see p.108) is total discharge of river at this point.

Cooperation.- Water-stage recorder inspected by Water District No. 7 AB.

Discharge, in second-feet, water year October 1945 to September 1946

1925-46: Maximum discharge, 706 second-feet May 28, 1927 (gage height, 4.00 feet), 

from rating curve extended above 600 second-feet; no flow during long periods in each 

year.

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

Canal diverts water from right bank of Big Wood River in sec. 9, T. 3 S., R. 18 E., 

from which point it approximately parallels river for 10 miles to head of North 

Gooding Canal in sec. 15, T. 4 S., R. 18 E., where water is either diverted into North 

Gooding Canal or returned to Big Wood River. Canal is used to avoid large channel 

losses in natural bed of river. No diversion above station.

acres of land in vicinity of Norwood. Figures given herein represent contents above 

5,101.0 feet. There is some usable storage below elevation 5,101.0 feet, but natural 

flow passing through reservoir when outlet gates are operating prevents withdrawal of 

storage to elevation of sill of gates. Gage read once daily. Time of reading variable.

Remarks.- Records good except those for period of ice effect, which are poor. Diring late 

fall of 1936, the Bureau of Reclamation cut a transmountain canal to divert a small 

flow from a tributary of Johnson Creek to Deadwood River Basin to supplement storage 

in Deadwood Reservoir. Discharge measurement of June 10 indicated flow in this canal 

of 34.6 second-feet.
