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, 1948. The work was begun in 1888 in conrection 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 11.37C gaging stations 

tn the 48 States and also at many in the Territories of Alaska and Hawaii. In July 1948, 

5,960 gaging 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 havs 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 seccnd-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 foot 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 water 

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 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 616,317 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, 1948, PART 13

"Contents" is a terra 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 OP 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 nonrecording gage or from a water-stage recorder that gives a continuous 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 measurements . The application of the daily mean gage height to those rating tables gives -the 

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

If the stage-discharge relation is subject to change because of frequent or continual 

change in the physical features that form the control, the daily mean discharge is determined by the "shifting-control method," in which correction factors based on individual discharge measurements and notes by engineers and observers are used in applying the 

gage heights to the rating tables. 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 "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 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 

the winter, which makes it impossible to compute the discharge in the usual marner. 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 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 

presented 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, location, drainage area, records 

available, average discharge, extremes of discharge, general remarks, and notations of revisions of previously published record. The location of the gaging station and the drainage area are obtained from the most accurate maps available. Under "Average discharge" is 

given the average discharge for the number of years indicated. It is not given for stations having less than 10 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 minim'um 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. Information pertaining to the accuracy of the records and conditions 

which affect the natural flow at the gaging station is given under "Remarks."

For some stations previously published records have been found to be In error on the 

basis of data or information obtained subsequently. 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 station description of all stations for which revised records have been 

published. Listed therein are all the reports in which revisions appear, 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 years, water years are indicated by 

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

1933. If there were no daily, monthly, or annual figures of discharge involved 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 we're 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 second-feet 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 second-feet 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.

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 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 nonrecording gages, the table of daily discharge gives the discharge
ACCURACY OF FIELD DATA AND COMPUTED RESULTS 5

corresponding to either once-daily readings of the gage, the mean of twic^-daily readings, 

or the mean gage height determined from gage-height graphs based on gage readings. For 

periods of rapidly changing stage, the daily mean discharge is determined from gage-height 

graphs based on gage readings, the frequency of which is stated in the station description.

In the table of 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.

Peak discharges with the times of their occurrence are listed below tl-e table of monthly 

discharge for most stations. All independent peaks above the selected bese are given. The 

base discharge, which is given in parentheses, is selectee; 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.

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 a station are published 

but is omitted from succeeding reports.

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 the records. "Excellent" indicates that, in general, the error in the daily re-.ords 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 or reservoirs or for other changes incident 

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

changes in res.ervoir contents, unless its inclusion is indicated. Even at those stations 

where adjustments are made, in some instances large errors in computed yields may occur 

when relatively large negative adjustments are applied or when evaporation Is large in 

comparison with the observed discharge. 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.
6 SURFACE WATER SUPPLY, 1948, PART 13

Many gaging stations on streams in the irrigated are.as 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 th^ 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 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

The results of stream-flow measurements are now published annually in 14 parts, each, 

part covering an area whose boundaries coincide with natural drainage features as indicated 

below:

Part 1. North Atlantic slope basins "(St. John River to York River).

2. South Atlantic slope and eastern Gulf of Mexico basins (James River to Mississippi 

	River).

3. Ohio River Basin.

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

years. Miscellaneous measurements at icany 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 thrt 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.

Reports 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 have been revised), as well as some records not contained in the annual 

series of water-supply papers. The following table gives the numbers and titles of these 

reports, arranged alphabetically, some by States and some by drainage basins.

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 1948 (1908-10, fragmentary).

Extremes.- Maximum contents during year, 850,820 acre-feet June 23, 23, July 3 (elevation, 

6,769.15 feet); minimum, 223,050 acre-feet Sept. 18 (elevation, 6,742.03 feet).

1908-48: Maximum contents, 857,220 acre-feet June 23, 1937 (elevation, 6,769.40 

feet); no usable contents on several days during period August to October 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 dam 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 between 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 daily at 8 a.m. 

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

release.

MUD LAKE BASIN

Mud Lake near Terreton, Idaho

Location.- Water-stage recorder, lat. 43°53', long. 112°24', in SW£ sec. 1, T. 6 N., R. 34

 E., a miles north of First Owsley pump house, 2j miles northeast of Terretcn, and 14 

miles southwest of Hamer; supplemental staff gage at pump house. Datum of each gage is 

4,775.33 feet above mean sea level.

Records available.- April 1921 to September 1948.

Extremes.- Maximum contents during year, 47,300 acre-feet May 19 (gage height, 8.g4 feet); 

minimum, 6,640 acre-feet Sept. 17; minimum gage height, 1.27 feet Sept. 16 (affected by 

wind).

1921-48: 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 vreter was released from Camas Creek into lake).

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

 water and surface tributaries augmented by well flows. For complete descriotion of Mud 

Lake region see Water-Supply Paper No. 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 1948. Other irrigation diversicns 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 feet. 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 Owsiey Canal Co.

a mile upstream from Beaver Creek.

Records available.- April 1925 to September 1948. 

Average discharge.- 22 years (1926-48), 23.9 second-feet.

Extremes.- Maximum discharge during year, 470 second-feet May 9 {gage height, 4.63 feet); 

no now at times.

1925-48: Maximum discharge, 900 second-feet probably May 3, 1938 {gage height, 3.9 

feet, datum then in use, from floodmark), from rating curve extended above 400 secondfeet; no flow June 1-7, 1926, and for many periods during 1930-48.

Remarks.- Records good except those below 10 second-feet, which are fair, and those for 

periods of ice effect or no gage-height record, which are poor. Diversions above and 

below station for irrigation and stock water.

Cooperation.- Gage-height record collected in cooperation with Water District No. 66 and 

nine winter field estimates furnished by that district.

Revisions.- W 813: 1935. Revised figures of discharge for the water year 1947 supering those published in Water-Supply Paper 1093, are given herewith.

a No gage-height record; discharge computed on basis of weather records and records for combination 

of Big Wood River and Big Wood Slough at Hailey and other nearby streams.
BIG WOOD RIVER BASIN 119

Big Wood Slough at Hailey, Idaho

Location.- Water-stage recorder, lat. £3°31'00'r , long. 114°19'30", in sec. 9, T. 2 N., 

K. IB 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 1948. 

Average discharge.- 33 years, 114 second-feet.

Extremes.- Maximum discharge during year, 257 second-feet Aug. 6 (gage height, 3.42 

reet); minimum recorded, 9.6 second-feet Jan. 26 (gage height, 1.41 fe-Jt).

1915-48: Maximum discharge observed, 419 second-feet June 6, 1921, from rating 

curve extended above 280 second-feet; 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 poor. Flow controlled at inoperative power plant half a mile upstrebm 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. Ill) is total discharge of river at this 

point.

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

BOISE RIVER BASIN 147

Diversions from Boise River between Dowling Ranch and Boise gaging stations, Idaho

Between Dowling Ranch and Boise gaging stations, 6 canals divert water from Boise 

River for irrigation.

Records of total diversion during irrigation seasons for each canal for years 1919-46, 

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

Survey. Records of daily diversion for each canal during irrigation seasons from 1916 to 

1948 on file in office of Idaho State Reclamation Engineer.

Records show summation of discharge for the six canals. Gage readings obtained 

daily or several times weekly, and frequent discharge measurements made. Records summarized under direction of W. E. Welsh, water-master for Boise River.

Correction.- Monthly figures for October to December 1946 shown in Water-Supply Paper 

1093 are a duplication of figures for April to June 1947. There should be no figures shown 

for October to December 1946.

PAYETTE RIVER BASIN 175

Deadwood Reservoir near Lowman, Idaho

Location.- 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 1935 to September 1948.

Extremes.- Maximum elevation observed-during year, 5,336.65 feet June 9, 10; minimum ob-

 served, 5,290.5 "feet Oct. 5.

PAYETTE RIVER BASIN

Deadwood River below Deadwood Reservoir, near Lowman, Idaho

Location.- Water-stage recorder, lat. 44°18', long. 115°39', in NE^ sec. 17, T. 11 N., R. 

YE., 300 feet upstream from Wilson Creek, a quarter of a mile downstream from Deadwood 

Dam at lower end of Deadwood Basin, 15 miles north of Lowman, and 18 miles upstream 

from mouth.

Drainage area.- 108 square miles.

Hecords available.- October 1926 to September 1948.

Average discharge.- 21 years (1927-48), 199 second-feet.

.Extremes.- Maximum discharge during year, 1,700 second-feet Sept. 13, 14 (gage height, 5.15 

feet); minimum not determined, occurred during period of no gage-height record when 

gates in dam were closed.

1926-48: Maximum discharge, 2,150 second-feet May 26, 1928 (gage height, 5.67 feet, 

site and datum then in use); small amount of leakage from reservoir for long periods 

during 1930-48 when gates in dam were closed.

Revisions.- The maximum discharge for the water year 1943 has been revised to 1,940 

second-reet June 1 (gage height, 5.46 feet), superseding figure published in WaterSupply Paper 983.

Remarks.- Records good except those below 10 second-feet, which are poor. Flow regulated 

since Nov. 2, 1930, by Deadwood Reservoir (see preceding page). During late fall of 

1936, Bureau of Reclamation cut a transmountain canal to divert a small flow from a 

tributary of Johnson Creek in Salmon River Basin to Deadwood River Basin for supplemental storage in Deadwood Reservoir. Discharge measurements of Oct. 15 and July 16 indicated -flow in this canal of 1.02 and 6.05 second-feet, respectively.

Revisions.- Revised figures of discharge, in second-feet, for the high-water period in the 

water year 1943, superseding those published in Water-Supply Paper 983, are given

Lake Fork Reservoir near McCall, Idaho

Location.- Staff gage and graduations on concrete gate-control structure cf dam on Lake 

ForTTTayette River, lat. 44°54', long. 116°03', in NWiNW^ 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 1948.

Extremes.- Maximum contents observed during year, 18,770 acre-feet July 1, 2 (elevat/ion, 

5,lib.IS feet); practically no storage at times during fall and winter.

1926-48: Maximum contents observed, 19,740 acre-feet June 19, 1941 (elevation, 

5,118.75 feet); practically no storage.above elevation 5,101.0 feet 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-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, £.0 feet above 

spillway crest). Dead storage unknown. Water is used for Irrigation of about 6,850 

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

5,101.0 feet. There is some usable storage below elevations 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. 

Storage figures from gage heights as observed.

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

* Winter discharge measurement made on this day.

e Gage reading inaccurate or not representative of mean for day; discharge computed on basis of 

ecords for other Salmon River stations. 

Note.- Stage-discharge relation affected by ice Nov. 21-24, Dec. 31 to Jan. 7, Jan. 9 to Feb. 28.
SALMON RIVER BASIN

Salmon River near French Creek, Idaho

Location.- Staff gage, lat. 45°26', long. 115°59«, in sec. 8, T. 24 N., R. 4 E., 100 feet 

downstream from Pall Creek, 2-j miles northeast of French Creek post office, and 16 miles 

east of Riggins.

Drainage area.-? 12,270 square miles.

Records available.- October 1944 to September 1948.

Extremes.- Maximum discharge observed during year, 75,300 second-feet May 29 (gage height, 

33.50 feet); minimum daily, 2,600 second-feet Jan. 28; minimum gage height observed, 

2.42 feet Jan. 1.

1944-48: Maximum discharge observed, that of May 29, 1948; minimum observed, 1,890 

second-feet Dec. 12, 1944 (gage height, 1.44 feet).

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

read twice daily. Amount of water diverted above station for irrigation is a 

negligible percentage of total flow.
