SURFACE WATER SUPPLY OF PACIFIC SLOPE BASINS IN CALIFORNIA, 1938

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, 1938. The work was begun in 1888 in connection with special studies 

relating to irrigation. Measurements of stream flow have been made at about 7,800 points 

in the United States and also at many points in Alaska and the Hawaiian Islands. In July 

1938, 3,830 gaging stations were being maintained by the Geological Survey and cooperating 

organizations. Many miscellaneous discharge measurements were made at 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. Acknowledgments for cooperation of the first kind are made in connection with the description of each station 

affected; cooperation of the second kind is acknowledged on page 9.

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 water flowing in a channel when the cross-sectional area is 1 square 

foot and the 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 run-off is distributed uniformly both as regards time and area.

"Run-off in inches" is the depth to which an area would be covered if all the water 

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

for comparing run-off with rainfall, which is usually expressed in inches.

An "acre-foot", equivalent to 43,560 cubic feet, is the quantity of water required to 

cover an acre to the depth of 1 foot. 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 run-off of 0.0372 inches from one square mile.

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

discharge."

"Control" is a term used to designate the natural section or reach of the channel or 

artificial structure below the gige which determines the stage-discharge relation at the

EXPLANATION OF DATA

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

of discharge, and general information used to supplement the gage heights and discharge

1
2 EXPLANATION OF DATA

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 gaging stations, equipped with water-stage recorder and measuring 

cable and car, are shown on plate 1.

Rating tables giving the discharge for any stage are prepared from the discharge 

measurements. The application of the daily gage height to these rating tables gives the 

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

The data presented for each gaging station in the area covered by this report usually 

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

and a table of monthly and yearly discharge and run-off. Skeleton rating tables are published except for those stations whose daily 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 determined from the best available maps, and information ir 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. Information under "Extremes" gives 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, and also the minimum discharge if useful; and the minimum gage height except when it is of no importance. Unless otherwise 

qualified, the maximum discharge corresponds to the crest s,tage, obtained by use of a 

water-stage recorder or a nonrecording gage read at the time of the crest. Likewise the 

minimum represents the lowest discharge, unless otherwise qualified. The peak discharge 

for the year with the time of its occurrence is given below the table of monthly discharge 

for sone stations. Selected lower peaks are also given if the peak discharge exceeded the 

mean discharge for that day by more than 10 percent. This supplementary information is 

generally not given for stations having drainage areas of less than 10 square miles or 

more than 10,000 square miles.

The table of daily discharge gives, for stations equipped with nonrecording gages, the 

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

of the gage. For flashy floods the mean daily 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 epuipped with water-stage recorders the table gives the 

discharge corresponding to the mean daily gage height except for stations on streams subject to sudden or rapid fluctuation. For stations subject to such fluctuation the mean 

daily gage height may not indicate the true mean daily discharge, which must be obtained 

by averaging the discharge for intervals of the day or by using the discharge integrator, 

an instrument for obtaining the mean daily discharge from a continuous gage-height graph 

and containing as an essential element the rating curve of the station.

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

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

column headed "Maximum" gives the maximum daily discharge and not the discharge when the 

water surface was at crest height. Likewise, in the column headed "Minimum" the quantity

given Is the minimum daily discharge. The column headed "Mean" is the average flow in 

cubic feet per second during the month.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream-flow data depends primarily (1) on the permanency of the stagedischarge relation and (2) on the accuracy of observation 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 daily records are accurate within 

5 percent; "good", within 10 percent; "fair", within 15 percent; and "poor", within 20 

percent or more.

The monthly means for any station may represent with high accuracy the quantity of 

water flowing past the gage, but the figures showing discharge per square mile and depth 

in inches may be subject to gross errors caused by the inclusion of large noncontributing 

districts in the measured drainage area, by lack of information concerning water diverted 

for irrigation or other use, or by inability to interpret the effect of artificial regulation of the flow of the river above the station. "Second-feet per square mile" and 

"run-off in inches" are therefore not computed if such errors appear probable. The computations are also omitted for stations on streams draining areas in which the annual 

rainfall 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, so that 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 gives a general idea of the flow at the station. The 

table of dally discharge allows more detailed studies of the variation in flow. It should 

tee borne in mind, however, that the observations in each succeeding year may be expected 

to throw new light on data previously published, and that greater degrees of refinement in 

computations and records may be warranted with increased data and use of improved 

equipment.

Note.- The reports that contain records after 1901 are given in the table on page 6.

The table on the following page gives, by years and drainage basins, the numbers of 

the papers on surface water supply published from 1899 to 1938. The data for any particular station will, in general, be found in the reports covering the years during which 

the station was maintained. For example, the data from 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.

the Geological Survey from time to time investigates outstanding floods and publishes 

special reports, in which are included records of hourly and daily discharge at gaging 

stations. Two such reports are being concurrently prepared covering streams within 

Part 11 as follows:

Water-Supply Paper 843 The floods of December 1937 in northern California. 

Water-Supply Paper 844 The floods of March 1938 in southern California.

1919-38: Maximum discharge occurred Mar. 2, 1938; practically no flow at times 

during 1929 and 1931-35.

Remarks.- Records good except those for period of missing gage heights, Mar. 2-14, which 

were computed on basis of rainfall-run-off studies and are poor. Discharge for 

period when control was under construction, Sept. 10-30, computed on basis of two 

discharge measurements and records for stations on nearby streams. Small diversion 

above station for domestic use. Results of discharge measurements furnished by city 

of San Bernardino.

TULARE LAKE BASIN L ' L

Tulare Lake in Kings County, Calif.

Location.- Staff gage, lat. 36°05', long. 119°44 T , at SW corner sec. 31, T. 21 S., R. 21

E., 12 miles southeast of Stratford. 

Records available.- Hay 1937 to September 1938. March 1906 to September 1920 (incomplete)

at several other sites. 

Extremes.- Maximum stage recorded during period May 1937 to September 1938, 195.5 feet

June 5, 1938. Maximum amount in storage, about 1,160,000 acre-feet, June 30, 1938. 

1906-38: Maximum stage probably occurred June 21, 1907 (gage height, 14.0 feet,

former site and datum); lake dry or practically so for parts of 1906, 1914, 1916, 1919,

1920-22, 1924-36, and 1937. 

Remarks.- Tulare Lake receives water from Kings, Kaweah, and Tule Rivers during high-water

periods and occasionally from Kern River, Deer Creek, and several small intermittent

streams. Its boundaries have been greatly altered in recent years by the construction

of levees and other reclamation work. Water reached lake from tributaries about Feb.

10, 1937, for first time since April 1923, and lake attained a stage of 192.3 feet

June 16, 1937 (contents about 420,000 acre-feet). It then receded until Dec. 14, 1937,

when it began to receive flow from flood of Dec. 11. It continued to rise slowly

through March 1938, with occasional periods of falling stage due to breaking of levees.

The spring- rise began about Apr. 15, 1938, and continued to the peak stage of June 5,

1938.

The amount of water in storage continued to increase, due to more levee breaks,

until June 30, 1938. Gage-height record furnished by Tulare Lake Reclamation District

No. 749.

GOOSE LAKE BASIN 253

Drew Creek near Lakeview, Oreg.

Location.- Staff gage, lat. 42°07', long. 120°36', in 3Ei sec. 4, T. 40 S., R. 18 E., 

at highway bridge half a mile downstream from mouth, of Willow Creek, 1 mile downstream 

from Drew Creek Dam, and 13 miles southwest of Lakeview.

Drainage area.- 211 square miles.

Records available.- January 1909 to September 1921, October 1925 to September 1938 in 

reports of U. S. Geological Survey. January 1909 to September 1936 in reports of 

State Engineer.

Average discharge.- 22 years, (1909-30, 1937-38) 66.2 second-feet, including diversion by 

North Drew canal.

Extremes.- Maximum discharge observed during year, 1,080 second-feet Apr. 25 (gage height, 

3.68 feet) by computation of flow over dam and through, gates: no flow at times.

1909-38: Maximum discharge, 3,000 second-feet (estimated) Mar. 1, 2, 1910; no 

flow at times.

Remarks.- Records fair except those for periods of missing gage heights,which were computed from known or estimated time of gate openings, or by interpolation or extrapolation and are poor. Staff gage read about twice a week. Considerable regulation caused 

by operation of Drew Creek Reservoir, 1 mile above station. Since March 1914 Worth Drew 

canal of Goose Lake Valley Irrigation Co. has diverted water around station. (See next

258 SACRAMENTO RIVER MAIN STEM

Sacramento River near Red Bluff, Calif.

Location.- Water-stage recorder, lat. 40°15'55", long. 122°10'50", in SEi sec. 34>T. 28 

N., R. 3 W., at lower end of Iron Canyon, half a mile downstream from Sevenmile Creek 

and 4 miles northeast of Red Bluff. Zero of gage is 252.6 feet above mean sea level.

Drainage area.- 9,300 square miles (not including Goose Lake Basin).

Records available.- January 1902 to September 1938. April 1895 to June 1902 at site at 

Jellys Ferry, 12 miles upstream from Red Bluff.

Average discharge.- 43 years, 11,340 second-feet.

Extremes.- Maximum discharge during year, 262,000 second-feet Dec. 11 (gage height, 36.50 

feet;, from rating curve extended above 130,000 second-feet logarithmically and on basis 

of velocity-area and A/d" studies; minimum, 3,020 second-feet Oct. 1 (gage height, 0.30 

foot).

1895-1933: Maximum discharge, that of Dec. 11, 1937; minimum, 2,400 second-feet 

Aug. 13, 1931, Sept. 9, 1934. Discharge for Feb. 3, 1909, previously published as 

273,000 second-feet, has been revised to 261,000 second-feet on basis of studies made 

of flood of Dec. 11, 1937.

Remarks.- Records excellent except those for periods of missing gage heights, Feb. 20 to 

Mar. 16 and July 9-17, which were computed on basis of recorded range of stage, 

partial recorder graph and records for station at Kennett, and are good. Some storage 

and many diversions above station.

Revisions.- Revised figures of discharge for high-water periods in the water years 1903-4, 

1906-7, 1908-9, 1913-14, 1914-15, 1926-27, and 1927-28, superseding those published 

in Water-supply Papers 251, 271, 298, 391, 411, 597-E, 651, and 671,are given below.

Middle Fork of Tuba River at Milton, Calif.

Location.- Water-stage recorder, lat. 39°31'22", long. 1EO°35'01", in SWi sec. 12, T. 

19 N., R. 12 E., at diversion dam of Nevada Irrigation District at old town site of 

Milton, 8 piles upstream from Sonth Fork of Middle Fork. Altitude, about 5,700 feet.

Drainage area.- 41 square miles.

Records available.- October 1928 to September 1934, October 1935 to September 1938. 

December 1925 to September 1928 at site 0.2 mile downstream.

Average discharge.- 10 years (1926-50, 1931-34, 1935-38), 105 second-feet (based on comblned flow or Middle Fork at this station and Milton-Bowman tunnel at outlet).

Extremes.- Maximum discharge during year, 6,800 second-feet Dec. 11 (gage height, 4.18 

feet) from rating curve extended above 1,500 second-feet by wier formula; no flow 

over dam for long periods.

1925-34, 1935-38: Maximum discharge, that of Dec. 11, 1937; practically all lowwater flow diverted after May 23, 1928.

Remarks.- Records good except those for period of missing gage heights, June 22-30, 

which were computed on basis of partial graph for June 22 and records for MiltonBowman tunnel at outlet and are fair. Milton-Bowman tunnel diverts water above 

station to Bowman Lake (see p. 30). Gage-height record furnished by Nevada Irrigation District.

AMERICAN RIVER BASIN 321

Seepage from Silver Lake near Kirkwood, Calif.

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

Just upstream from road crossing and half a mile northeast of Silver Lake Dam. Altitude, about 7,200 feet.

Records available.- October 1929 to September 1938.

Extremes.- Maximum discharge observed during year, 19 second-feet July 28; no flow 

during most of year.

1929-38: Maximum discharge observed, 25 second-feet June 9, 1930; no flow during 

most of each year.

Remarks.- Records fair. Gage read once daily. Ho flow when Silver Lake gage height is 

below 14.0 feet. This is a record of largest amount of seepage from Silver Lake 

through the porous rock formation; other seepage from Silver Lake is of little or no 

consequence. The discharge at this station combined with that for Silver Lake outlet 

near Kirkwood (see p. 320) represents practically entire outflow from Silver Lake.
