SURFACE WATER SUPPLY OF PACIFIC SLOPE BASINS IN CALIFORNIA, 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, 

5,600 gaging stations, Including those In Hawaii, were being maintained by the Geological 

Survey and cooperating organizations. Miscellaneous discharge measurements were made t 

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 gaglng-statlon records In each volume. In the present 

volume, the section on cooperation of the second kind appears on page 13.

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 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 toe 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.

1
2 SURFACE WATER SUPPLY, 1945, PART 11

"Contents" Is a term applied to the volume of water In a reservoi^. 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 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 figure 1.

Rating tables giving the discharge for any stage are prepared from the discharge measurements. The application of the dally mean gage height to those 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 the physical features that form the control, the dally 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 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 dstermlnlng 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 Hie 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 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 b'y this report the data 

presented comprise a descrlptlon'of the station, a table showing the dally discharge of 

the stream, and a table of monthly and yearly dlecharge 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 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 dally mean -discharge, which must be obtained by averaging the discharge 

for parts of the day or by using tiie 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 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 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 dally discharge. The column headed 

"Maximum" gives tiie 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 tiie 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 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 time and clock time was moved back 1 hour, or to 1 a.m. This made September 30 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 dally 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 time. 

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 from the total second-foot-days 

for the month without adjustment for the fact that September 30 v;as 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 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 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 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 

noncontributlng 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 dally 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 

eubject 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 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 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

COOPERATION

In California the work was done under cooperative agreements with the State Department 

of Public Works, C. H. Purcell, director, and Edward Hyatt, state engineer; the East Bay 

Municipal Utility District; Santa Clara Valley Water Conservation District; San Bernardino, 

Riverside, Orange, Los Angeles, Ventura, and Santa Barbara Counties; and the cities of San 

Diego, Santa Barbara, Santa Cruz, and Lodi. In Oregon the work was done under cooperative 

agreement with the State of Oregon, Chas. E. Stricklin, State engineer.

Financial assistance was furnished by the Corps of Engineers, U. S. Army, for the operation of 41 gaging stations and by the Bureau of Reclamation of the United States Department of the Interior for the maintenance of 36 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 Niles was borne by the city and county of San 

Francisco.

Assistance in collecting records was also rendered by the following organizations: In 

Californla,by The California Oregon Power Co., southern California Edison Co., Ltd., Pacific 

Gas & Klectric Co., city of Sacramento, Emma Rose & Hobart Estate Co., and Merced, Modesto, 

Table Mountain, Thermalito, Turlock, and Woodbrldge 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 the Geological 

Survey, Glenn L. Parker, chief hydraulic engineer, Carl G. Paulsen, assistant chief hydraulic engineer, and Rudolph G. Rasel, chief of the division of surface water (until 

June 14, 1945). The data for the gaging stations were collected and prepared for publication under supervision of district engineers as follows: In California (except for Fall 

Creek and KLamath River near Copco), H. D. McGlashan; in Oregon and for Fall Creek and 

Klamath River near Copco, Calif., G. H. Canfield. The work in Oregon was done in collaboration with Charles E. Stricklin, State engineer.

The records were reviewed and the manuscript prepared for publication under the direction of B. J. Peterson, hydraulic engineer in charge, and F. J. Flynn, associate engineer,

42 SANTA ANA RIVER BASIN

Santa Ana River at Riverside Narrows, near Arlington, Calif.

Location.- Water-stage recorder, lat. 33°57'55", long. 117°27'55", In Jurupa (Stearns) 

Grant, at Pedley Road Bridge, 3.3 miles northwest of Arlington, Riverside County. 

Datum of gage, 669.87 feet above mean sea level {levels by Riverside County engineer). 

Auxiliary high-water gage at site 1.2 miles upstream.

Records available.- January 1929 to September 1945.

Average discharge.- 15 years (1929-37, 1938-45), 63.3 second-feet.

Extremes.- Maximum discharge during year, 2,500 second-feet Feb. 2 (gage height, 3.94 

reet;; minimum dally discharge, 21 second-feet July 16, 20, 21.

1929-45: Maximum discharge, 100,000 second-feet Mar. 2, 1938, by slope-area 

method; minimum, 20 second-feet Aug. 3, 1937.

Remarks.- Records below 100 second-feet are fair In general but for many Individual 

days are poor. Considerable diurnal fluctuation occurs throughout season of low 

flow, but It Is unlikely that variation In discharge from day to day Is as great 

as that Indicated by dally figures. Records poor above 100 second-feet. Several 

diversions for Irrigation and power development above station.

Discharge, in second-feet, water year October 1944 to September 1945

West Branch Feather River near Yankee Hill, Calif.

Location.- Water-stage recorder, lat. 39°42', long. 121°34', in SWi sec. 5, T. 21 N., R. 

4 E. , at highway bridge, 1.4 miles downstream from Concow Creek and 2 miles west of 

Yankee Hill. Altitude of gage, about 1,100 feet (from topographic map).

Drainage area.- 145 square miles.

Kecoras available.- September 1930 to September 1945.

Average discharge?- 15 years, 342 second-feet.

Extremes.- Maximum discharge during year, 6,240 second-feet Feb. 2 (gage height, 15.04 

reet); minimum, 5.4 second-feet Sept. 8.

1930-45: Maximum discharge, 21,400 second-feet Dec. 11, 1937 (gage height, 30.3 

feet), from rating curve extended above 15,000 second-feet; minimum, 0.3 second-foot 

Jan. 8, 1937 (gage height, 1.69 feet).

Remarks.- Records good. Spring Valley ditch (see p. 358) diverts water from Concow Creek 

below Lake Wilenor (capacity, 8,000 acre-feet) for power development and irrigation. 

Dewey, Miners, and Hendricks Canals divert from headwaters of West Branch Feather 

River into Butte Creek Basin (see p. 345 ) for power development in De Sabla and Center-- 

ville plants of Pacific Gas & Electric Co. Round Valley Reservoir (capacity, 1,285 

acre-feet) and Philbrook Reservoir (capacity, 4,875 acre-feet) provide storage on 

headwaters for these three canals.

380 FEATHER RIVER BASIN

Bowman Lake near Graniteville, Calif.

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

 Bownan Dam on Canyon Creek. 4 miles east of Graniteville. Datum of gage is 5,000.0 

feet above mean sea level [levels by Nevada Irrigation District); gage readings have 

been reduced to elevations above mean sea level.

Drainage area.- 30 square miles.

Records available.- December 1926 to September 1945.

Extremes.- Maximum contents observed during year, 70,400 acre-feet June 5, 6, 21 (ele-

 vation, 5,565.8 feet); minimum observed, 9,360 acre-feet Jan. 28 (elevation, 5,467.9 

feet).

1926-45: 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, 1944.

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. 368), and releases it through BowmanSpaulding Canal (see p. 382) which conveys it to reservoirs of Pacific Gas & Electric 

Co. Vlater Is eventually used fcr irrigation by Nevada Irrigation District. Record 

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

all of which is available for release.

Cooperation.- Record of daily gage heights furnished by Nevada irrigation District.

AMERICAN RIVER BASIN 397

Sliver Lake Outlet near Kirkwood, Calif.

Location.- Water-stage recorder, lat. 38°40', long. 120°08', in SW-J sec. 32, T. 10 N., 

R. 17 E., 1,000 feet downstream from Silver Lake Dam and 3 miles southwest of Kirkwood. 

Altitude of gage, about 7,200 feet (from topographic nap).

Drainage area.- 14.9 square miles.

Kecoras available.- September 1922 to September 1945.

Average discharge?- 23 years, 32.6 second-feet.

Extremes ( regulated).- Maximum discharge during year, 332 second-feet May 8 (gage height, 

4.00 reet); minimum, 0.4 second-foot Nov. 12, 13.

1922-45: Maximum discharge, 504 second-feet Dec. 11, 1937 (gage height, 5.10 feet), 

from rating curve extended above 190 second-feet; nininun, 0.1 second-foot during 

periods when reservoir gate was closed.

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

wmcn are poor. Contents In Sliver Lake was 3,060 acre-feet on Sept. 30, 1944, and 

3,500 acre-feet on Sept. 30, 1945. In addition to water released through dan and 

over spillway some escapes from Silver Lake through porous rock formation. The 

discharge at this station combined with seepage from Silver Lake near Kirkwood 

(see following page) represents practically entire outflow from Silver Lake.

Cooperation.- Water-stage recorder graph, furnished by Pacific Gas & Electric Co., 

obtained in connection with a Federal power Commission project.

most of each year.

Remarks.- Records fair. Gage read only occasionally. Ho flow when Silver Lake gage 

neigtit is below 14.0 feet. This record represents largest amount of seepage from 

Silver Lake through porous rock formation. The discharge at this station combined 

with that for Silver Lake Outlet near Kirlorood (see preceding page) represents 

practically entire outflow from Silver Lake.
