SCOPE OF WORK

nils volume is one of a serlss of 14 reports presenting results of tteasureraerts of 

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

water year ending September 30, 1943. The work was begun In 1888 In connection with 

special studies relating to Irrigation. Measurements of the flow of streams ancT of the 

stage and contents of lakes and reservoirs have been made at about 9,670 gaging stations * 

In the 48 States and also at many gaging stations In Alaska and Hawaii. In July 1943, 

5,120 gaging stations, Including those In Hawaii, were being maintained by the Geological 

Survey and cooperating organizations. Miscellaneous discharge measurements were aa.de at 

many other points.

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

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

kind is acknowledged In connection with ttie description of each .station affected*; in 

this report cooperation of the second Jcind Is acknowledged on page 14, .

DEFINITION OF TOT1S

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 foot per second.

"8eoond-feet per square- mile" Is the average number of cubic feet of water flowing per 

second f «m each squara 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 dept': of 1 

foot and Is equivalent to 43,660 cubic'feet. The term Is commonly used In connection with 

storage for irrigation.

"Second-foot-day" IB the volume of water represented by a flow of 1 second-fcxst 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 ttie channel, or an artificial structure.

"Contents" Is a term applied to the volume of water In a reservoir, not inoluling 

water In bank storage unless so 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 nonrecordlng 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 figvres 1 and 2.

Rating tables giving the discharge for any stage are prepared from the discharge measurements. The application of the daily mean gage height to these rating 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 frequent or continual 

change In Hie physical features that form the control, the dally mean discharge is 

determined by the "shifting-control method," in viilch 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 tines 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 det«raination of discharge. Information requisite for determining the slope or fa] 1 la obtained 

by means of an auxiliary gage set at some distance from the base gage. At sons 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 ft 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 usurl manner. Discharge for periods of ice effect Is computed on the basis of the gage-helfht record and 

occasional winter discharge measurements, consideration being given to th« available 1 reformat ion on tataperature and precipitation, notes by gage observers and engineers, and 

comparable records of discharge for stations la the same or nearby basins. The days 

Included In the periods of lee effect and the days during the winter period on vftleh discharge measurements were made are indicated In the table- by symbols referring to footnotes 

or are/given In a general note following the table.

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

presented comprise a description of the station, a table showing the dallf discharge of 

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

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

greater part of the year was determlmd by the shifting-control method, tt * 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 ttie flew 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 sears of record. Under "Extremes" are given the maximum'discharge and gage 

height} the mlnlmim discharge If there Is little or no regulation; the minimum dally diecharge if there is extensive regulation (also the minimum discharge If useful); and the 

minlfflum 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 nonrecordlng 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 stations having drainage areas of less than 10 square miles or more than 10,000 square miles or If t're peak 

discharges usually exceed the corresponding mean discharges for the day by less than 10 

percent.

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

the discharge In second-feet corresponding to once-daily readings of the gage o- the mean 

of twice-dally-readings. For flashy floods the dally 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. For stations equipped with water-stage recorders, except those 

on streame 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 

daily mean gage height my 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.

In the table of monthly dlsetarge the column headed "Second-foot-days" gjves the sum 

for each month of the figures given In the table of dally discharge. The coluim headed 

"Maximum" gives Hie maximum dally discharge, not the momentary discharge when the 

water surface was at crest stage. Likewise, in the column headed "minlMim" the quantity 

given Is ttie minlmm 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 coaprise a description of the station and a monthly summary table of stage and contents. For som reservoirs 

a table showing dally contents is given. A skeleton table of capacity at glveri 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 f""om 

standard tiae to "war tlas," and clock time In the several zones of the country was moved 

ahead 1 hour, or to 3 a.m. Records of dally discharge prior to February 9, 194?-, have 

been computed on the basis of standard time. Records subsequent to that date tnve been 

computed on the basis of war time. To convert war time to standard time, subtnct 1 

hour.
6 SURFACE WATER SUPPLY, 1943, PART 11

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 dally rp«»rds 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 ard yearly mean 

discharge and runoff are, In general, more accurate than the dally 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 "secondfeet 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 noncontrltouting 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 Stetes 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 dally discharge affords opportunity for more detailed studies 

of the variation in flow. A"s further observations In each succeeding year may be expected 

to throw new light on data previously published, It should be borne in mine that such data 

are subject to revision in succeeding water-supply papers.

COOPERATION

in California the work was done under cooperative agreements with the strte Department 

'of Public Works, Frank W. Clark, director until January 1943 and C. H. Pur-jell thereafter, and Edward Hyatt, State engineer; the East Bay Municipal Utility District; Santa 

Clara Valley Water Conservation District; San Bernardlno, Riverside, Orange, Los Angeles, 

Venture, and Santa Barbara Counties; and the cities of San Diego, Santa Barbara, Santa 

Cruz, and Lodl. In Oregon the work was done under cooperative agreement with the State of 

Oregon, Chas. E. Strlcklln, State engineer.

Financial assistance was furnished by the Corps of Engineers, U. S. Army, for the opera*- 

tlon of 41 gaging stations and by the Bureau of Reclamation of the United Spates Department of the Interior for the maintenance of 4 gaging stations. The entire expense of the 

Investigation of stream flow In the Tuolumne River Basin made for the Hetch Hetchy project 

and of the flow of Alameda Creek near Miles was borne by the city and county of San 

Francisco. <

Assistance In collecting records was also rendered by the following organizations? In 

California, by The California Oregon Power Co., the National Park Service of the United 

States Department of the Interior, Southern California Edison Co., Ltd., Pa-rifle Gas & 

Electric Co., city of Sacramento, Emma Rose & Hobart Estate Co., and Merced, Woodbrldge, 

Thermallto, and Table Mountain Irrigation Districts; In Oregon, by The California Oregon 

Power Co.

DIVISION OF WORK

The stream-gaging work was conducted by the water-resources branch of tl« Geological 

Survey, oienn L. Parker, chief hydraulic engineer, Carl G. Paulsen, assistant chief 

hydraulic engineer, and Rudolph 0. Kasel, chief of the division of surface waters. The 

data for the gaging stations were collected and prepared for publication urder supervision 

of district engineers as follows: In California (except for Fall Creek an<" KLamath River 

near Copco), H. D. Mcaiashan; In Oregon and for Fall Creek and JClamatti Rlvrr near Copco, 

Calif., a. H. Canfleld. The work In Oregon was done In collaboration with Charles E.

FEATHER RIVER BASIN 329

Bowman Lake near Granltevllle, Calif.

Location.- Staff gage, lat. 39°27', long. 120°39', in SWi sec. 5, T. 18 N., R. 12 E., at 

Bowman Dam on Canyon Creek, 4 miles east of Granltevllle. Datum of gage Is 5,000.0 

feet above mean sea level (levels by Nevada Irrigation District); gage readi-gs have 

been reduced to elevations above mean sea level.

Drainage area.- 30 square miles.

Records available.- December 1926 to September 1943.

tactremea.- Maximum contents observed during year, 70,500 acre-feet June 1 (elevation,

5755579 feet); minimum observed, 21,400 acre-feet Dec. 22, 23 (elevation, 5,494.9 feet).

1926-43: Maximum contents observed, 70,500 acre-feet June 16, 17, 1937, June 1, 

1943 (elevation, 5,565.9 feet); contents less than 1,000 acre-feet and therefore 

doubtful, at times during 1926, 1928-31, 1933-35, 1937, 1939.

Remarks.- Lake Is formed by one rock-fill and one concrete-arch dam; completed and

storage began In November 1926. Usable capacity, 68,200 acre-feet between elevations 

5,400 feet (bottom of outlet tunnel) and 5,563 feet (crest of concrete-arch dam) above 

mean sea level. Flashboards are occasionally added, Increasing elevation to 5,564.5 

feet and capacity to 69,400 acre-feet. Lake receives water from Middle Fork Yuba 

River, through Milton-Bowman tunnel (see p. 321), and releases It through BownanSpauldlng Canal (see p. 331 ) which conveys It to reservoirs of Pacific Gas & Electric 

Co. Water Is eventually used for Irrigation by Nevada Irrigation District. Record of 

dally contents, computed from gage readings made at odd times, shows total contents, 

all of which is available for release.

Cooperation.- Record of dally gage heights furnished by Nevada Irrigation District.

Seepage from Sliver Lake near Klrkwood, Calif.

Location.- Staff gage, lat. 38°40', long. 120°07', In SWi sec. 32, T. 10 N., R. 17 E., 

 JusTUpstream from road crossing and half a mile northeast of silver Lake Dam. Altitude of gage, about 7,800 feet (from topographic map) 

Records available.- October 1929 to September 1943. 

Average Qiscnarge.- 14 years, 3.73 second-feet.

BS.- raxm discharge observed during year, 20 second-feet June 20, 21; no flow

most of year.

1929-43: Maximum discharge observed," 25 second-feet June 9, 1930; no flow during 

most of each year.

Remarks.- Records fair. Gage read once dally, when read. No flow when Silver Lake gage 

neignt Is below 14.0 feet. This record represents largest amount of seepage from 

Silver Lake through porous rock formation; other seepage from Sliver Lake Is of little 

or no consequence. The discharge at this station combined with that for Sliver Lake 

Outlet near Klrkwood (see preceding page) represents practically ent're outflew from 

Silver Lake. '

Cooperation.- Gage-height record, furnished by Pacific Gas & Electric Co., obtained In 

 connection with a Federal Power Commission project.
