SURFACE WATER SUPPLY OF SNAKE RIVER BASIN, 1945

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, 1945. 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 10,300 gaging stations

In the 48 States and also at many in the Territories of Alaska and Hawaii. In July 1945,

5,6001gaglng stations, including those in Hawaii, were being maintained by the Geological

Survey and cooperating organizations. Miscellaneous discharge measurements were made

during the water year at many other points.

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

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

kind Is acknowledged in connection with the description of each station affected; cooper­

ation of the second kind Is acknowledged, under the heading "Cooperation," In the Intro­

ductory matter that precedes the gaging-statlon 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 diecharge of a stream whose channel Is 1 square foot In cross-sectional area and

whose average velocity Is 1 foot per second.

"Second-feet per square nile" 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 dis­

tributed uniformly both as regards time and area.

"Runoff in Inches" is the depth to which an area would be covered If all the water

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

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

An "acre-foot" Is the quantity of water reqlrirred to cover an acre to the depth of

1 foot and is equivalent to 43,560 cubic feet. The term Is commonly used In connection

with storage for irrigation.

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

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

represents a runoff of 0.0372 Inch from 1 square mile.

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

and discharge."

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

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

of the channel, or an artificial structure.

2 SURFACE WATER SUPPLY, 1945, PART 13

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

the 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 daily flow. The records of stage are obtained either from

direct readings on a nonrecordlng gage or from a water-stage recorder that gives a con­

tinuous record of the fluctuations. Measurements of discharge are made with a current

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

discharge. 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 meas­

urements. The application of the dally 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 de­

termined by the "shifting-control method," In which correction factors based on Individ­

ual discharge measurements and notes by engineers and observers are used in applying the

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

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

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

control" method, described above.

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

reservoirs, tributary streams, or other.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 determi­

nation of discharge. Information requisite for determining the slope or fall is obtained

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

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

change of stage Is used as a factor 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

tne winter, which makes It impossible to compute the discharge in the usual manner. Dis­

charge 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 in­

formation on temperature and precipitation, notes by gage observers and 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 this report the data

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

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

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

greater part of the year was determined by the shifting-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 dally discharge If

there Is extensive regulation (also the minimum discharge If use.ful); and the mlninum gage

height (unless It Is of no Importance). Unless otherwise qualified, the maximum discharge

corresponds to the crest sta^e, obtained by use of a water-stage recorder or a nonrecord-

Ing 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 nore than 10,OOO 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 dally mean

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

Indicate the true dally mean discharge, which must be obtained by averaging the discharge

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 nonrecordlng gages, the table of dally 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 dally mean discharge Is determined

from gage-height graphs based on gage readings made once or twice dally 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 dally discharge. The column headed

"Maximum" gives the maximum dally 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 dally discharge. The column headed "Mean" gives the average flow In cubic

feet per second during the month.

For most gaging stations on lakes and reservoirs the data presented comprise a descrip­

tion of the station and a monthly summary table of stage and contents. For some reservoirs

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

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

from succeeding reports.

TIME BASIS

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

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

ahead 1 hour, or to 3 a.m. At 2 a.m., war time, on September 30, 1945, a change was made

PUBLICATIONS 5

back to standard tine and clock time was moved back 1 hour, or to 1 a.m. This made Sep­

tember "0 a 25-hour day. Time given herein for the water year 1945 prior to the change on

September 30 refers to war time; time after the change refers to standard time. To convert

war time to standard time, subtract 1 hour. Records of daily discharge prior to February 9,

1942, were computed, and those subsequent to September 30, 1945, will be computed on the

basis of standard time; records between those dates were computed on the'basis of war tine.

The discharge given for September 30, 1945, Is the mean for 25 hours. The mean discharge

and runoff for the month of September have been computed fron the total second-foot-days

for the month without adjustment for the fact that September 30 vras a 25-hour day. The

small error resulting from this procedure has been disregarded.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream-flow data depends primarily on (1) the permanency of the stage-

discharge 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 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 per­

cent; 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 or 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

noncontrlbutlng 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 situ­

ated 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 more detailed studies of the

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

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

subject to revision in succeeding water-supply papers.

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

and drainage basins, are listed by number on page 9. 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 covered 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

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

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

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

relative order as the streams and gaging stations in the body of the report. An index of

the 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

Papers 871 to 884 (see table on p. 8), contains, for the area covered by that report, a

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

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

Drainage area.- 816 square miles.

Records available.- July 1908 to September 1945 (1908-10, fragmentary).

Extremes.- Maximum contents during year 855,170 acre-feet July 4 (elevation, 6,769.32 feet); minimum, 300,990 acre-feet Oct. 1 (elevation, 6,745.78 feet).

1908-45: Maximum contents 857,220 e.cre-feet June 23, 1937 (elevation, 6,769.40 feet); no usable contents on several days during period August to October 1919 (ele­ vation, 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 dam was raised in 1916 increasing the usable capacity to 790,000 acre-feet. In 1917, by dredging 'she outlet, the capacity was further increased to 847,000 acre-feet between elevations 6,730 feet (top of baffles to sluices) and 6,769 feet (top of spillway gates). Water is used for irrigation Ln Snake River Valley, Idaho. Gage read once daily at 8 a.m. Contents as given herein are computed from elevation at that time; all available for release.

Datum of each gage is 4)775.33 feet above mean sea level.

Records available.- April 1921 to September 1945.

Extremes.- Maximum contents during year, 44,200 acre-feet June 19 (gage height, 8.57 feet); minimum observed, 9,020 acre-feet Nov. 1 (gage height, 2.26 feet).

1921-45: Maximum contents observed, 61,660 acre-feet May 5, 1923 (gage height, 9.20 feet); practically no contents Oct. 1 to Nov. 15, 1937 (at 4 p.m. Nov. 15 water was diverted from Camas Greek into lake).

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 Water- supply Paper No. 818. Water for Irrigation is diverted from lake and tributaries by pumping and gravity. During 1945 season diversion dam in Camas Creek diversion canal was not in place. Area of lake is varied from time to time by changes in dikes. High winds occasionally disturb recording of lake stages. Figures given herein represent contents above gage height -4.0 fpet. Capacity table prepared from surveys made by Geological Survey adjusted for changes in dikes.

Cooperation.- Water-stage recorder inspected by Water District No. 66 and supplemental staff-gage readings furnished by Owsley Canal Co.

Records available.- January 1919 to September 1945.Extremes.- Maximum contents observed during year, 40,570 acre-feet June 26 (gage height,

63.67 feet); minimum observed, 9,599 acre-feet Sept. 16-18 (gage height, 31.40 feet).1919-45: Maximum contents observed, 41,270 acre-feet May 30, 1938 (gage height,

64.20-feet); no available contents during periods in 1919, 1920, 1924, 1926, 1929, 1931-35; minimum gage height observed, 6.3 feet Aug. 5, 1934.

Remarks.- Reservoir is formed by earth-and rock-fill dam, which was reconstructed 1917-18; storage impounded by original dam not recorded. Capacity, 38,400 acre-feet between gage heights 7.0 feet (bottom of outlet tunnel) and 62.0 feet (crest of spillway). Dead storage reported to be about 125 acre-feet. Water is used for Irrigation of lands In Big Lost River Irrigation district. Considerable seepage around dam because of Its porous foundation, but the greater part of this water returns to Big Lost River between reservoir and station below reservoir, near Mackay.

* Winter discharge measurement made on this day. 'a Ho gage-height record; discharge computed on 'basis of weather records and records for Arrowrock

Reservoir and other stations in Boise River Basin.ti Stage-discharge relation affected by ice.Time basis: Mountain war time up to 2 a.m., Sept. 30, 1945; mountain standard time thereafter.

To convert war time to standard time, subtract 1 hour.

134: BOISE RIVER BASIN

Arrowrock Reservoir at Arrowrock, Idaho

Location.- Graduations on upstream face of dam on Boise River, lat. 43°36', long. 115°55 I > in EE sec. 13, T. 3 N., R. 4 E., at Arrowrock, 22 miles by road east of Boise. Datum of gage is at mean sea level (surveys of Bureau of Reclamation).

Drainage area.- 2,210 square miles.Records available.- October 1917 to September 1945.Extremes.- mximum contents observed during year, 300,600 acre-feet June 10, 22-24 (ele­

vation, 3,218.9 feet); minimum observed, 4,112 acre-feet Oct. 9 (elevation, 3,007.8 feet).

1917-45: mximum contents observed, 300,900 acre-feet May 4, 5, 1939 (elevation, 3,219.0 feet); no usable contents during period in each of several years wnen sluice gates were open and natural flow was passing through reservoir.

Remarks.- Reservoir is formed by gravity-section concrete-arch dam completed in 1915 and raised 5 feet in 1937; storage began in 1915. Capacity, 291,600 acre-feet between ele­ vation 2,956 feet (11 feet below center line of sluice gates, 0.5 feet below sill) and 3,216 feet (crest of movable spillway at highest position). Dead storage negligible. Figures given herein represent total contents (including bank storage), which, project officials state, may have been reduced as much as 5,000 to 6,000 acre-feet by deposition of silt. Water is used for irrigation of lands in Boise Valley. Gage read once daily about 8 a.m.

Revisions.- Revised figure of contents for Mar. 31, 1943, is 97,540 acre-feet and revised figures of change in contents for months of mrch and April 1943 are -14,660 and +180,160 acre-feet, respectively, superseding figures published in Water-Gupply Paper 98o.

Cooperation.- Gage readings and yield table furnished by Bureau of Reclamation.

160 PAYETTE RIVER BASIN

Deadwood Reservoir near Lawman, Idaho

Locatloa.- Staff gage, lat. 44°18', long. 115°39', in SEj sec. 8, T. 11 N., R. 7 E., at dam on Deadwood River, 15 miles north of Lowman. Datum of gage is at mean sea level (levels by Bureau of Reclamation).

Drainage area.- 108 square miles.

Records available .- October 1925 to September 1945.

Extremes.- Maximum elevation observed during year, 5,335.1 feet June 27 to July 1; mini­ mum observed, 5,287.0 feet Oct. 10.

1935-45: Maximum elevation observed, 5,337.1 feet June 1, 2, 1943; minimum observed, 5,260.1 feet Oct. 1, 1935.

Remarks.- Reservoir is formed by concrete arch dam, completed in 1930; storage began Nov. 2, 1930. Reported capacity, 160,400 acre-feet between elevations 5,230.0 feet (minimum operating level because of fish protection, 27 feet above sill of emergency gate in front of needle valve) and 5,334.0 feet (crest of spillway). Storage below elevation 5,230.0 feet, about 1,500 acre-feet. Water is used to augment flow of Payette River at Black Canyon power plant near Emmett. During late fall of 1936, Bureau of Reclamation cut a transmountain canal to divert a small flow of water from a tributary of Johnson Creek in Salmon River Basin to Deadwood River Basin for supple­ mental storage in Deadwood Reservoir. Discharge measurement and field estimate made on June 21 and Aug. 11, 1945, indicated flow in this canal of 44.8 and 4 second-feet, respectively. Gage read once daily.

Cooperation.- Gage readings furnished by Bureau of Reclamation.

PAYETTE RIVER BASIN 169

Lake Fork Reservoir near McCall, Idaho

Location.- Staff gage and graduations on concrete gate-control structure, of dam on Lake Fork Payette 'River, lat. 44°54', long. 116°03', In NWiNWi sec. 13, T. 18 N., R. 3 E., 3 miles east of McCall. Datum of gage Is at mean sea level (levels by Lake Irrigation District).

Records available.- April 1926 to September 1945.

Extremes.- Maximum contents observed during year, 17,760 acre-feet June 24 (elevation, 5,117.52 feet); no storage during fall and winter.

1926 45: Maximum contents observed, 19,740 acre-feet June 19, 1941 (elevation, 5,118.75 feet); probably no storage above elevation 5,101.0 feet during fall and winter each year,

Remarks.- Reservoir Is formed by earth- and rock-fill dam completed in 1926. Capacity, 16,940 acre-feet between elevations 5,101.0 feet (lower limit of capacity table, 4.0 feet above gate sill of outlet) and 5,117.0 feet (top of flashboards, 5.0 feet above spillway crest). Dead storage unknown. V/ater is used for irrigation of about 6,800 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 dally. Time of reading variable. Storage figures from gage heights as observed.

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

Drainage area.- 54.7 square miles.

Records available.- October 1942 to September 1945.

Extremes.- Maximum discharge during year, 777 second-feet May 10 (gage height, 4.80 feet); minimum not determined, probably occurred during period of ice effect; minimum gage height recorded, 1.79 feet Nov. 16.

1942-45: Maximum discharge, 810 second-feet May 28, 1943 (gage height, 5.09 feet), from rating curve extended above 450 second-feet; minimum observed, 7.8 second-feet Feb. 6, 1943, discharge measurement; minimum gage height recorded, 1.79 feet Nov. 25, 1943, Nov. 16, 1944.

Remarks.- Records good except those for period of ice effect, which are poor. During late fall of 1936, the Bureau of Reclamation cut a transmountaln 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 21 and field estimate of Aug. 11 indicated flow in this canal of 44.8 and 4.0 second-feet, respectively.
