SURFACE WATER SUPPLY OF PACIFIC SLOPE BASINS IN CALIFORNIA, 1952

SCOPE OF WORK

This volume is one of a series of 18 reports presenting measurements of stage, discharge, and content of streams, lakes, and reservoirs in the United States during the 

water year ending September 30, 1952. Since 1888, when the United States Geological 

Survey first studied streamflow in relation to problems of irrigation, similar measurements have been made at more than 12,600 gaging stations in the 48 States and at many 

others in the Territories of Alaska and Hawaii. On September 30, 1952, the Geological 

Survey and cooperating organizations were maintaining 6,700 gaging stations, including 

those in Alaska and Hawaii. Miscellaneous discharge measurements were made at many other 

points in the 1952 water year.

COOPERATION

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

of Public Works, F. B. Durkee, director, and A. D. Edmonston, State engineer; San 

Bernardino County; Calaveras County Water District; Orange County Flood Control District; 

San Luis Obispo County Flood Control and Water Conservation District; City of Santa 

Barbara and Santa Barbara County Water Agency. In Oregon the work was done under cooperative agreement with the State of Oregon, C. E. Stricklin, State engineer.

Assistance in the form of funds or services was given by the Corps of Engineers, 

Department of the Army, in collecting records published herein for 38 gaging stations, by 

the Bureau of Reclamation of the United States Department of the Interior for 64 gaging 

stations, and by the Bureau of Indian Affairs, United States Department of the Interior 

for one gaging station. The entire expense of the investigation of streamflow 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.

The following organizations aided in collecting records: In California, The California 

Oregon Power Co., Southern California Edison Co. Pacific Gas & Electric Co., and Merced, 

Modesto, Table Mountain, Thermalito, Turlock, Oakdale, South San Joaquin, and Woodbridge 

Irrigation Districts; in Oregon, The California Oregon Power Co.

DIVISION OF WORK

The stream gaging was done by the Water Resources Division of the Geological Survey, 

Carl G. Paulsen, chief hydraulic engineer, under the direction of Joseph V. B. Wells, 

chief of the Surface Water Branch. The data for stations in the several States were 

collected and prepared for publication under the supervision of the district engineers 

at the offices listed below. The records were reviewed and the manuscript prepared for 

publication under the direction of B. J. Peterson, chief, Annual Reports Section.

Information of a more detailed nature than that published for most of the gaging 

stations given in this report is on file in the district offices listed above. Provisional 

records of discharge prior to publication, and other unpublished data concerning the gaging 

station records may usually be obtained from the district office.

DEFINITION OF TERMS AND ABBREVIATIONS

The terms of streamflow and other hydrologic data, as used in this report, are defined 

as follows:

Cubic foot per second (cfs) 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.

Cubic feet per second per square mile (cfsm) is the average number of cubic feet of 

water flowing per second from each square mile of area drained, assuming that the runoff 

is distributed uniformly in 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. The term is used 

for comparing runoff with rainfall, which is also usually expressed in inches.

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 relation to storage 

for irrigation.

Cfs-day is the volume of water represented by a flow of 1 cubic foot per second 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 the relation between gage height and the amount of water 

flowing in a channel, expressed as volume per unit of time.

Control designates a feature downstream from the gage that determines the stage-discharge relation at the gage. This feature may be a natural constriction of the channel, 

a long reach of the channel, or an artificial structure.

Contents is the volume of water in a reservoir. Unless otherwise indicated, volume is 

computed on the basis of a level pool and does not include bank storage.

The drainage area of a stream at a specified location is that area, measured in a horizontal plane, which is so enclosed by a topographic divide that direct surface runoff from 

precipitation normally would drain by gravity into the river above the specified point. 

Figures of drainage area given herein include all closed basins, or noncontributing areas, 

within the area unless otherwise noted.

DOWNSTREAM ORDER OF LISTING GAGING STATIONS

Beginning with the series of reports for the water year ending September 30, 1951, the 

order of listing gaging-station records was changed. In this report, in a downstream 

direction along the main stem all stations on a tributary entering above a main-stem 

station are listed before that station. If a tributary enters between two main-stem 

stations, it is listed between them. A similar order is followed in listing stations 

on first rank, second rank, and other ranks of tributaries. To indicate the rank of any 

tributary on which a gaging station is situated and the stream to which it is immediately 

tributary, each indention in the listing of gaging stations in the table of contents of 

this report represents one rank. This downstream order and system of indention show 

which gaging stations are on tributaries between any two stations on a main stem and the 

rank of the tributary on which each gaging station is situated.
EXPLANATION OF DATA 3

The order of listing used before the publication of the 1951 report listed first all 

stations on the main stem from headwaters toward mouth, then all stations on the uppermost 

tributary to the main stem from the tributary's source to mouth, and then all stations from 

source to mouth of the uppermost tributary to the tributary.

EXPLANATION OF DATA

The base data collected at gaging stations consist of records of stage and measurements 

of discharge. In addition, observations of factors affecting the stage-discharge relation, 

weather records, and other information are used to supplement base data 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 fluctuations. 

Measurements of discharge are made with a current meter by the general methods adopted 

by the Geological Survey on the basis of experience in stream gaging since 1888. These 

methods are described in Water-Supply Paper 888 and are also outlined in standard textbooks on the measurement of stream discharge. Typical structures in use at gaging stations 

are shown in figure 1.

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

relation curves defined by discharge measurements. If extensions to the rating curves 

are necessary to define the extremes of discharge, they are made on the basis of indirect 

measurements of peak discharge (such as slope-area or contracted-opening measurements, 

computation of flow over dams or weirs, and by other methods), velocity-area studies, and 

logarithmic plotting. 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. If the stage-discharge relation for a station is 

temporarily changed by the presence of aquatic growth or debris on the control, the daily 

mean discharge is computed by what is. essentially the shifting-control method.

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

reservoirs, tributary streams, or other sources. This necessitates the use of the slope 

method in which the slope or fall in a reach of the stream is a factor in determining 

discharge. Information requisite for determining the slope or fall is obtained by means 

of an auxiliary gtge set at some distance from the base gage. At some stations the stagedischarge relation is affected by changing stage. If so, 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, and it becomes 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 other stations in the same or nearby basins. If the 

stage-discharge relation is affected by ice, this information is given in a note to the 

table. No mention is made of occasional days of ice effect if the degree of accuracy of 

daily records is not changed.

FIGURE I. GAGING-STATION STRUCTURES
The data herein presented generally comprise a description of the station, a skeleton 

rating table, and a table showing the daily discharge and monthly and yearly discharge and 

runoff of the stream.

The description of the station gives the location, drainage area, records available, 

type and history of gages, average discharge, extremes of discharge, general remarks, and 

notations of revisions of the previously published record. The location of the gaging 

station and the drainage area are obtained from the most accurate maps available. River 

mileage, given under "Location" for some stations, is that determined and used by the Corps 

of Engineers unless otherwise noted. Under "Gage" are given the type of gage currently in 

use and the datum of the present gage above mean sea level, and a condensed history of the 

types of gages, locations, and datums of previous gages for which discharge records are 

generally equivalent to those at the present site. Under "Average discharge" is given the 

average discharge for the number of years indicated. It is not given for stations having 

fewer than five 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 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, a crest-stage indicator, or a nonrecording gage read at the time of the crest. If the maximum gage height did not occur 

at the same time as the maximum discharge, it is given separately. Information pertaining 

to the accuracy of the records and conditions which affect the natural flow at the gaging 

station is given under "Remarks."

Previously published records of some stations have been found to be in error on the 

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

Listed therein are all the reports in which revisions have been published, 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 water years only one number is 

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

1933. If no daily, monthly, or annual figures of discharge are concerned 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 were 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 cubic feet per second 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 cubic feet 

per second 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.

Skeleton rating tables are published for all stations except.those at which the daily 

discharge for the greater part of the open-water period was determined by the shiftingcontrol method, the slope method, or other special methods involving an equivalent adjustment to the gage height of more than one-tenth foot.

6 SURFACE WATER SUPPLY, 1952, PART 11

For stations equipped with water-stage recorders, except those on streams subject to 

sudden or rapid fluctuation, the daily 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 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 daily 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 corresponding to once-daily readings of the gage, or to the mean of twice-daily 

readings, or to 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 daily discharge, the values for the maximum day and the minimum day for 

each month are underlined. If the value is repeated, it is underlined only on the first 

day of its occurrence.

In the monthly summary below the daily table, the line headed "Total" gives the sum of 

the daily values; it is the total cfs-days for the month. The line headed "Mean" gives 

the average flow in cubic feet per second during the month. Runoff for the month may be 

expressed in cubic feet per second per square mile (line headed "Cfsm"), or in inches (line 

headed "in."), or in acre-feet (line headed "Ac-ft"). Values for cubic feet per second per 

square mile and runoff, in inches, are omitted if the drainage area includes large noncontributing areas, or if the average annual rainfall over the drainage basin is usually less 

than 20 inches.

In the yearly summary below the monthly summary, the values of maximum are the maximum 

daily discharges, not the momentary discharges when the water was at crest stage. Likewise, the minimums in this summary are the minimum daily discharges.

Peak discharges and the times of their occurrence and corresponding gage heights of 

most stations are listed below the table of daily and monthly discharge. All independent 

peaks above the selected base are given. The base discharge, which is given in parentheses, is selected 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.

Footnotes to the table of daily discharge indicate periods when discharge was computed 

or estimated by unusual or special methods during periods of no gage-height record and ice 

effect, or by other effects that reduce the degree of accuracy of the records. Days on 

which discharge measurements were made are indicated by asterisk and footnote unless they 

were made at frequent regular intervals, in which instance the general frequency of discharge measurements is given under "Remarks" in the station description.

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 the reservoir are published, 

but it is omitted from succeeding reports.
SURFACE WATER SUPPLY, 1952, PART 11 7 

ACCURACY OP FIELD DATA AND COMPUTED RESULTS

The accuracy of streamflow data depends primarily on (1) the stability 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 discharge, and interpretation of records.

The station description states the degree of 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 nearly accurate than the daily records.

Runoff at some stations, as indicated by the monthly mean, may vary widely from natural 

runoff, owing to diversion, consumption, regulation by storage, increase or decrease in 

evaporation due to artificial causes, or to other factors. For such stations, values of 

cubic feet per second per square mile and runoff, in inches, are not published unless 

storage or diversipn records are included to indicate 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 it is so stated. 

Even at those stations where adjustments are made, large errors in computed runoff may 

occur when relatively large negative adjustments are made or when evaporation is large in 

comparison with the observed discharge.

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 actually show the water supply available at the stations for further development, 

because water must first be supplied to existing irrigation systems.

PUBLICATIONS

To facilitate publication of the annual series of reports, the area of the United 

States.is divided into 14 parts whose boundaries coincide with certain natural drainage 

lines. Formerly, the results of streamflow measurements were published in 14 volumes, one 

for each of the 14 parts. Beginning with the reports for 1951, the records are published 

in 18 volumes, there being 2 volumes each for Parts 1, 2, 3, and 6. The boundaries of the 

various parts are indicated by the following list and the map in figure 2.

Note.--Water-Supply Papers 298, 299, and 300 contain records of flow at all gaging stations in 

Part 11, some of which supersede records published in Water-Supply Papers 38, 39, 51, 66, 75, 85,

PUBLICATIONS
10 SURFACE WATER SUPPLY, 1952, PART 11

The records at most of the stations discussed in these reports extend over many 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 are listed in the same order as the 

streams and gaging stations in- the body of the report. An index of the records obtained 

before 1904 has been published in Water-Supply Paper 119.

Each of the reports on the surface-water supply for the year 1939 (Water-Supply Paper 

881 for the Pacific slope basins in California) contains, for the area included in that 

report, a summary of yearly discharge at gaging stations at which 10 or more complete 

years of record had been collected. These summaries were reprinted separately.

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

annual series of water-supply papers. The following table lists reports of this type for 

the Pacific slope basins in California.

HYDROLOGIC CONDITIONS

Although runoff for the water year 1952 as a whole was well above normal for the entire 

Pacific slope basins in California, drought conditions prevailed in extreme southern 

California for the months of October and November and again during the months of August 

and September. Floods of 1952 for California are described in Water-Supply Paper 1260 

(now in preparation). For three key gaging stations in the area covered by this report, 

a comparison of the monthly and yearly mean discharge during the 1952 water year with the 

median discharge for the 25-year period 1921-45 is shown in figure 3 on the following

Note. The runoff from the basin of Sweetwater River is equal to the algebraic sum qf (l) change 

in contents, (2) draft, (3) evaporation, and (4) spill plus leakage, minus (5) the quantity imported 

from Colorado River. Computation of runoff from Sweetwater River basin using the figures in the 

above table, and resulting in the figures in the last column of the table, gives results that may be 

considerably less accurate than would be possible if a simple gaging station could be maintained on 

the river. This arises from the difficulty of computing the runoff from Sweetwater River basin as 

the residual of several larger quantities which are not susceptible of measurement with a precision 

necessary to produce a final answer within desirable limits of accuracy, particularly for months of 

very low runoff.
SAN DIEGO RIVER BASIN 25

Boulder Creek at Cuyamaca Reservoir, near Julian, Calif.

Location.--Lat 32°59'20", long. 116°35'10", in NE£ sec. 5, T. 14 S., R. 4 E., on outlet 

tower at Cuyamaca Dam, 7 miles south of Julian.

Drainage area.--12.0 sq mi.

Records available.--October 1935 to September 1952 (inflow to Cuyamaca Reservoir; rainrail on reservoir water surface deducted, October 1939 to September 1944). June 1912 

to September 1926, records not equivalent as they represent only outflow (draft) from 

Cuyamaca Reservoir.

Gage.--Staff gage read once daily. Datum of gage is 4,600.2 ft above mean sea level 

(1& Mesa, Lemon Grove, and Spring Valley Irrigation District benchmark).

Average runoff. 8 years (1944-52), 2,550 acre-ft per year (3.51'cfs).

Remarks.--Records of runoff represent all water reaching Cuyamaca Reservoir, including 

rainfall on reservoir, computed on basis of records of storage, release (draft), spill, 

leakage, and evaporation. Capacity and area ratings for reservoir based on a resurvey 

made in the fall of 1949. Capacity of reservoir at spillway level (gage height, 35.4 

ft), 11,540 acre-ft. No dead storage. Small diversions for local use near dam. Water 

is released down Boulder Creek to El Capitan Reservoir.

Cooperation.--Records of reservoir operation furnished by La Mesa, Lemon Grove, and Spring 

Valley Irrigation District.

SAN DIEGO RIVER BASIN 27 

San Vicente Creek at San Vicente Dam, at Poster, Calif.

Location. Lat 32°54'40", long. 116°55'35", in sec. 31, T. 14 S., R. IE., at left end of 

upstream face of San Vicente Dam, 0.5 mile north of Poster.

Drainage area. 75 sq mi, approximately.

Records available.--January to April 1915, October 1936 to September 1952. Published as 

"at Foster" prior to October 1941 and as "near Poster" October 1941 to January 1943.

Gage. Staff gage read once daily. Datum of gage is 460.0 ft above mean sea level. January to April 1915, staff gage at about same site at different datum. October 1936 to 

Sept. 30, 1941, water-stage recorder at about same site at different datum. Oct. 1, 

1941, to Jan. 25, 1943, water-stage recorder at site 1 mile upstream at different datum.

Remarks. Records of inflow represent all water reaching San Vicente Reservoir, not only 

from basin of San Vicente Creek, including rainfall on reservoir, but also imported 

Colorado River water. Total inflow is computed on basis of records of storage, release 

(draft), spill, leakage, and evaporation. Colorado River water delivered to this reservoir through aqueduct of San Diego County Water Authority during year, as shown in 

table, is included in figures of inflow. Capacity and area ratings for reservoir are 

dated 1943. Capacity of reservoir at spillway level (gage height, 190.00 ft), 90,230 

acre-ft. Dead storage, 350 acre-ft below lowest outlet at gage height 33.0 ft (revised), included in these records. No diversion above reservoir. Water is released as 

required for municipal use.

Note. Runoff from basin of San Vicente Creek Is equal to algebraic sum of (1) change In contents, 

(2) draft, (3) evaporation, and (4) spill plus leakage, minus (5) the quantity Imported from Colorado River. However, computation of runoff from San Vicente Creek basin using figures In above 

table gives results that may be in error, frequently being negative. This arises primarily from the 

difficulty of computing runoff from San Vicente Creek basin as the residual of several larger quantities which are not susceptible of measurement with a precision necessary to produce a final answer 

within reasonable limits of accuracy. The natural runoff from this basin during the year was about 

13,000 acre-ft. Colorado River water, conducted to San Vicente Reservoir by San Diego aqueduct, Is 

measured at head of aqueduct rather than at point of discharge Into reservoir.
28 SAN DIEGO RIVER BASIN

San Diego River near Santee, Calif.

Location.--Lat 32°49'20", long. 117°03'25", in Ex Mission San Diego Grant, on right bank 

in Mission Gorge, 6 miles west of Santee, San Diego County.

Drainage area.--380 sq mi.

Records available.--May 1912 to September 1952 (incomplete prior to 1920).

is 205 

iles upGage.--Water-stage recorder and unfinished rubble dam control. Altitude of gage ft (from topographic map). Prior to Nov. 10, 1920, staff gage at site If mil' 

stream at different datum.

Average discharge.--37 years (1912-15, 1917-18, 1919-52), 31.8 cfs; median of yearly mean 

discharges, 5.7 cfs.

Extremes.--Maximum discharge during year, 4,390 cfs Jan. 18 (gage height, 5.57 ft); no 

flow for several months.

1912-52: Maximum discharge, 70,200 cfs Jan. 27, 1916 (gage height, 25.1 ft, site 

and datum then in use); no flow at times during most years.

Remarks.--Records good except those for periods of no gage-height record, which are fair. 

Discharge measurements generally made twice a month. Small flows of less- than 0.05 cfs, 

from rising water at the gage, have been called zero, but there was no flow Aug. 8 to 

Oct. 24, 1951. Flow regulated by El Capitan, Cuyamaca, and San Vicente Reservoirs 

(see pp. 25,26,27). Diversions above station by city of San Diego for municipal supply 

and by La Mesa, Lemon Grove, and Spring Valley Irrigation District.

yearly inflow, 21 cfs.

Remarks. Records of runoff represent all water reaching Lake Henshaw, exclusive of 90 

percent of rainfall on water surface of lake and supplemental water obtained by pumping 

ground water from area adjacent to lake, computed on basis of records of storage, release (draft), spill, leakage, evaporation, rainfall, and ground-water pumpage. Capacity and area ratings for-lake are based on resurvey made in October 1951. Capacity of 

reservoir at spillway level (gage height, 107.00 ft), 194,300 acre-ft. No dead storage. Since storage of water was .begun, runoff as computed has been exclusive of 90 

percent of rainfall on water surface of lake. During the year, the amount of rainfall 

excluded was 2,254 acre-ft. No diversion above Lake Henshaw. No flow over spillway 

since dam was completed. Water is released down San Luis Rey River for diversion downstream for irrigation, power, and domestic use.

Note. Net evaporation, as used In computing this record, Is total evaporation less 90 percent of 

rainfall on water surface of reservoir. Supplemental water obtained by pumping ground water from 

area adjacent to lake Is subtracted from Inflow to obtain runoff. Howeyer, as thus computed the results may be considerably In error, occasionally being negative. This arises primarily from the 

difficulty of computing runoff from basin as the residual of several larger quantities which are not 

susceptible of measurement with precision necessary to produce final answer within reasonable limits 

of accuracy.

Temeoula Creek at Vail Dam, near Temecula, Calif. 

(Formerly published at Temeoula Creek at Nigger Canyon, near Temeoula)

Location. Lat 33°29'40", long. 116°59'00", In Pauba Grant, at Vail Dam In upper end of 

Nigger Canyon, 0.2 mile downstream from Arroyo Seco, and 10 miles east of Temecula, 

Riverside County.

Drainage area. 319 sq mi.

Records available. October 1948 to September 1952. January 1923 to September 1948 at site 

300 ft downstream, published as "at Nigger Canyon, near Temecula"; records not equivalent owing to change in natural water loss resulting from creation of Vail Lake. October 1948 to September 1951, published as "at Nigger Canyon, near Temecula", records are 

for draft and spill only from Vail Lake.

Sage. Water-stage recorder. Datum of gage is 1,350.0 ft above mean sea level (levels by 

Bureau of Reclamation). Prior to Oct. 16, 1930, at about same site at several different 

daturas. Oct. 16, 1930, to September 1948, at site 300 ft downstream at different datum.

Remarks. Records of runoff represent all water reaching Vail Lake, including rainfall on 

reservoir surface, computed on basis of records of storage, release (draft), spill, and 

evaporation. Capacity and area ratings for lake are based on a survey made in 1947. 

Capacity of lake spillway level (gage height, 120.00 ft), 49,370 acre-ft. Dead storage, 

4 acre-ft below lowest outlet at gage height 3.5 ft, included in these records. No diversion above lake. Water is released down Temecula Creek for diversion about 1 mile 

below dam as required.

Cooperation. Records computed in cooperation with Santa Margarita Ranch (U. S. Navy) and 

Pauba Ranch.

56 SANTA ANA RIVER BASIN

Mill Creek near Craftonville, Calif.

Location. La t 34°05'20", long. 117°02'25", in NE^NE^ sec. 13, T. 1 S., R. 2 W., on left 

bank 50 ft downstream from bridge on State Highway 190-D, 5 miles upstream from mouth, 

and 5 miles northeast of Craftonville.

Drainage area. 39.9 sq mi.

Records available . January 1919 to September 1938, October 1947 to September 1952.

Gage. Water-stage recorder. Datum of gage is 2,916.36 ft above mean sea level (Southern 

California Edison Co. benchmark). Prior to August 1926, at site 100 ft upstream at 

different datums. August 1926 to Mar. 2, 1938, at site 500 ft downstream at different 

datum (destroyed by flood).

Average discharge.--24 years (1919-38, 1947-52), 13.4 cfs; median of yearly mean discharges, 

2.5 cfs.Average combined discharge, creek and canals, 24 years (1919-38, 1947-52), 

35.3 cfs; median of combined yearly mean discharges, 26 cfs.

Extremes.--Maximum discharge during year, 738 cfs Dec. 30 (gage height, 8.63 ft), from

rating curve extended above 160 cfs by logarithmic plotting; no flow Nov. 6, 7, July 23. 

1919-38, 1947-52: Maximum discharge, 18,100 cfs, Mar. 2, 1938, result of slope-area 

determination of peak flow; no flow at times in some years.

Remarks. Records fair except those for periods of no gage-height record and those above 

150 cfs, which are poor. Discharge measurements generally made twice a month. Mill 

Creek Power Canals Nos. 1,2, and 3, divert from points 100 ft, 3 and 6 miles above 

station, respectively. Combined flow of Mill Creek and Mill Creek power canal, Nos. 

1, 2, and 3, is given in table on following page.

SANTA ANA RIVER BASIN

Mill Creek near Mentone, Calif.

Location. Lat 34°05'10", long. 117°06'S5", in SE^NW^seo. 17, T. 1 S., R. 2 W., on downstream side of right pier of Bear Valley pipeline crossing, 0.2 mile upstream from 

mouth, 1.5 miles northeast of Mentone, and 5 miles southeast of East Highlands.

Records available.--February 1939 to September 1952.

Gage.--tfeter-stage recorder and broad-crested weir. Altitude of gage is 1,780 ft (from 

topographic map).

Average discharge. 13 years, 3.37 cfs; median of yearly mean discharges, 1.1 cfs.

Extremes.--Maximum discharge during year, 249 cfs Dec. 5 (gage height, 4.72 ft); no flow 

during part of year.

1939-52: Maximum discharge, 1,500 cfs Dec. 23, 1945 (gage height, 6.5 ft), result 

of slope-area determination of peak flow; no flow during parts of each year.

Remarks.--Records fair except those for periods of no gage-height record, which are poor. 

The Zanja diverts most of low-water flow above station. Pumpage from wells along 

stream above station for irrigation affects surface flow at station.

Discharge, in cubic feet per second, water year October 1951 to September 1952

SANTA ANA RIVER BASIN 

Lytle Creek (east channel) at San Bernardino, Calif.

Location. Lat 34°05'45", long. 117°19'50", in San Bernardino Grant, on left bank 10 ft 

downstream from Mount Vernon Avenue Bridge in San Bernardino, San Bernardino County.

Records available.--January 1929 to September 1952.

Gage.--Water-stage recorder. Altitude of gage is 1,050 ft (from topographic map). Prior 

to Mar. 2, 1938, at site a quarter of a mile upstream at different datum.

Extremes.--Maximum daily discharge during year, 5.4 cfs Jan. 16; minimum daily, 0.2 cfs 

on June 21.

1929-52: Maximum discharge, 21,500 cfs Mar. 2, 1938, result of contracted-opening 

determination of peak flow; no flow during parts of many years.

Maximum total discharge of Lytle Creek (east and west channels combined), 29,400 

cfs Mar. 2, 1938.

Remarks.--Records good except those for periods of no gage-height record, which are fair. 

Discharge measurements generally made twice a month. Minor diversions for irrigation 

and to debris cone for ground-water recharge. Since 1945, Lytle Creek flood-control 

dam 1.5 miles above station has diverted flood flow away from this channel and carried 

it direct to Warm Creek. Capacity of flood-control diversion channel, 30,000 cfs. A 

maximum of 300 cfs of low-stage flow can be diverted to east channel at dam when desired. Water over spillway of dam would enter this channel.

76 SANTA ANA RIVER BASIN

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

Location. Lat 33°57'55", long. 117°27'55", in Jurupa (Stearns) Grant, on right bank at 

downstream side of bridge on Pedley Road, 1.8 miles downstream from Union Pacific Railroad bridge, 3.3 miles northwest of Arlington, and 12 miles upstream from Temescal 

Creek.

Records available. January 1929 to September 1952.

Gage.--Water-stage recorder. Datum of gage is 669.87 ft above mean sea level (levels by 

Riverside County engineer). Prior to Nov. 15, 1943, water-stage recorder If miles upstream at different datum. During this period temporary stations were maintained at 

different sites and daturas within a quarter of a mile of the permanent gage.

Extremes. Maximum discharge during year, 4,880 cfs Jan. 18 (gage heignt, 4.92 ft); minimum daily, 31 cfs May 11.

1929-52: Maximum discharge, 100,000 cfs Mar. 2, 1938, on basis of slope-area determination of peak discharge; minimum daily, 20 cfs on several days during August and 

September 1947.

Remarks. -.-Records good. Discharge measurements are generally made once a week. Plow regulated by Big Bear Lake (see p. 53). Natural flow of stream affected by ground-water 

withdrawals and diversions for irrigation and return flow from irrigated areas. The 

Metropolitan feter District of Southern California released 19,237 acre-ft of Colorado 

River water into Santa Ana River about l.l'miles above the station during year.

SANTA ANA RIVER BASIN

Day Creek near Etiwanda, Calif.

Location. La t 34°11'00", long. 117°32'25", in SW£ sec. 8, T. 1 N., R. 6 W., on left bank 

0.2 mile downstream from confluence of two main forks and 6 miles north of Etiwanda.

Drainage area.--4.8 sq mi, approximately.

Records available.--January 1929 to September 1952. Combined creek and diversions, October 1950 to September 1952.

Gage. Water-stage recorder and broad-crested weir. Altitude of gage is 2,940 ft (from 

topographic map). Prior to Mar. 2, 1938, at site 200 ft upstream at different datum 

(destroyed by flood). May 2 to Sept. 2, 1938, at site 200 ft downstream at different 

datum.

Average discharge. 23 years, 4.44 cfs; median of yearly mean discharges, 3.4 cfs.

Extremes.--Maximum discharge during year, 214 cfs Dec. 5 (gage height, 2.81 ft); minimum 

daily, 0.1 cfs several periods during year.

1929-52: Maximum discharge, 4,200 cfs Mar. 2, 1938, based on rainfall-runoff 

studies; no flow Oct. 5 to Nov. 1, 1950.

Remarks. Records good except those for periods of no gage-height record, which are fair. 

Discharge measurements generally made twice a month. Etiwanda Water Co. diverts water 

above station. For records of combined discharge of creek and diversion see following 

page. In addition, an infiltration gallery, unwatering gravel in the bed of the 

stream Just below gaging station, produced 800 acre-ft during year.

Creek, 3 miles downstream from Prado Dam, and 6 miles west of Corona, Riverside County.

Records available. January 1919 to November 1942, fey 1945 to November 1952 (irrigation 

seasons only since October 1940). Prior to October 1950, published as "near Prado."

Gage. Water-stage recorder. Datum of gage, 407.34 ft above mean sea level, unadjusted. 

Prior to fey 1945, on left bank 700 ft south of common corner of Orange, Riverside, 

and San Bernardino counties at datum 2.39 ft higher, fey 1, 1945, to May 30, 1946, at 

datum 1.00 ft higher.

Extremes. Maximum discharge, 100,000 cfs (estimated) Mar. 2, 1938 (gage height, 17.3 ft, 

site and datum then in use, from floodmarks in gage well); minimum, 25 cfs Aug. 18, 

1929, Aug. 24, 1936.

Remarks. Records good except those for period of no gage-height record, which are fair. 

Discharge measurements generally made once a week. Plow regulated by Prado Reservoir 

(capacity, 222,800 acre-ft) and Big Bear Lake (see p. 53). The normal flow is affected 

by ground-water withdrawals, diversions for irrigation, return flow from irrigated 

areas, and release of Colorado River water to the Santa Ana River by the Metropolitan 

Water District of Southern California (see Santa Ana River at Riverside Narrows).

Cooperation. Thirty-four discharge measurements furnished by Orange County Flood Control 

District, through J. A. Bradley, flood-control engineer.

92 SANTA ANA RIVER BASIN

Santiago Creek at Santiago Dam, near Villa Park, Calif.

Location.--Lat 33°47'10", long. 117°43'35", in Lomas de Santiago Grant, on upstream face 

near right side of Santiago Dam, 1.5 miles east of Irvine Park and 5 miles east of 

Villa Park, Orange County.

Drainage area.--63 sq mi, approximately.

Records available.--October 1931 to September 1952.

Gage. Staff gage read on last day of each month. Datum of gage is mean sea level.

Average runoff.--21 years, 14,250 acre-ft per year (19.7 cfs); median of yearly runoff, 

7,900 acre-ft (11 cfs).

Remarks.--Records of runoff represent all water reaching Santiago Reservoir, including 

rainfall on the reservoir, computed on basis of records of storage, draft, spill, 

waste, leakage, and evaporation. This earth-fill dam was completed in December 1931. 

Capacity and area ratings for the reservoir are dated December 1930. Capacity of 

reservoir at spillway level (gage height, 790.0 ft), 25,000 acre-ft. Dead storage 

below lowest outlet included in these records. Water released to conduits as required 

for irrigation is called draft; water released back to creek is called waste. Evaporation is computed from records from a standard United States Weather Bureau station 

at crest of dam. Spill, waste, and leakage, combined, represent all water passing 

down Santiago Creek from Santiago Dam. Minor diversions in basin above this reservoir

Cooperation.--Records of reservoir operation and draft furnished by Serrano and Carpenter 

Irrigation Districts and Irvine Co.

98 SAN GABRIEL RIVER BASIN 

San Gabriel River near Azusa, Calif.

Location-. Lat 34°10'10", long. 117°53il6", in SW£ sec. 13, T. 1 N., R. 10 W., on right 

bank 1 mile downstream from Morris Dam and 3 miles northeast of Azusa.

Drainage area. 211 sq mi.

Records available. 1894 to September 1952.

Gage.--Water-stage recorder. Datum of gage is 867.59 ft above mean sea level (from Los 

Angeles County Flood Control District benchmark). Prior to August 1917, staff gages 

and August 1917 to Sept. 30, 1937, water-stage recorders at several sites from If to 

2 miles downstream at different datum. Oct. 1, 1937, to Feb. 21, 1938, water-stage 

recorder at site half a mile downstream at different datum. Feb. 22, 1938, to Feb. 7, 

1939, water-stage recorder at site a quarter of a mile upstream at different datum. 

Datum lowered 4.35 ft May 9, 1950.

Average discharge. Average natural discharge of river, adjusted for diversions and regulation and evaporation in Cogswell, San Gabriel, and Morris Reservoirs, 57 years 

(1895-1952), 159 cfs; median of yearly mean natural discharge, 120 cfs (Cogswell and 

San Gabriel Reservoirs were formerly known as San Gabriel River flood-control reservoirs Nos. 2 and 1, respectively.)

Extremes . Maximum daily discharge during year, 3,530 cfs Jan. 18; no flow during part of 

year.

1894-52: Maximum discharge, 65,700 cfs Mar. 2, 1938, computation of peak flow over 

Morris Dam; no flow for several months in most years.

Remarks. Records fair. Discharge measurements generally made once a week during periods 

of flow. Flow regulated by Cogswell (formerly called San Gabriel Reservoir No. 2) and 

San Gabriel (formerly called San Gabriel Reservoir No. 1) Reservoirs (combined capacity, 

54,500 acre-ft, revised) and by Morris Reservoir (capacity, 35,000 acre-ft). Azusa 

Canal (formerly power canal of Southern California Edison Co.) diverts above high-water 

level of Morris Reservoir about 3 miles above station. The Metropolitan Water District 

of Southern California reports a discharge of 629 acre-ft of Colorado River water into 

San Gabriel River below Morris Dam and above station during period October to December. 

They also furnished records of natural runoff for San Gabriel River computed on basis 

of actual flow in river and Azusa canal, adjusted for storage and evaporation in Cogswell, San Gabriel, and Morris Reservoirs as shown in table below. These figures of 

runoff are equivalent to combined records of San Gabriel River and Southern California 

Edison Go's canal as published from 1894 to 1933

Records available . December 1930 to September 1952. Prior to October 1938, published as 

at Juncal Reservoir, near Montecito."

Gage. Water-stage recorder on Jameson Lake and water-stage recorder and sharp-crested 

weir on outlet conduit. Datum of gage is 2,021.6 ft above mean sea level (Bureau of 

Reclamation benchmark), or 2,000 ft above .arbitrary datum (called sea level) generally 

used for works in this vicinity.

Remarks. Records of total inflow represent all water reaching Jameson Lake, including 

rainfall on lake, computed on basis of records of storage, diversion to city of Montecito (draft), spill and release to river, and evaporation. Records of net runoff exclude rainfall on water surface, computed on basis of area and records of precipitation. Capacity and area ratings for this lake are based on surveys made in 1948. 

Lake capacity at spillway level (gage height, 225.0 ft), 6,760 acre-ft. Dead storage, 

268 acre-ft, below lowest outlet at gage height 139.0 ft, included in these records. 

Records are computed as of 6 p.m. on last day of each month. There is no regulation 

or diversion above Jameson Lake. A part of flow of Alder Creek, which enters Santa 

Ynez River 2 miles downstream from Juncal Dam, is diverted from above elevation 2,250 

ft to Jameson Lake, and is included in these records.

Purisima Grant, on downstream side of center pier of bridge on State Highway 150, 1.5 

miles east of Lompoc, Santa Barbara County, and 2.5 miles downstream from Salslpuedes 

Creek.

Drainage area. 790 sq mi.

Records available. November 1906 to September 1918 (1909, gage heights only), April 1925 

to September 1952.

Gage. Water-stage recorder. Datum of gage is 79.28 ft above mean sea level, datum of 1929. 

~irrior to Dec. 14, 1928, staff gage and Dec. 14, 1928, to Nov. 30, 1939, water-stage recorder, at site 600 ft upstream at various daturas.

Average discharge. 27 years (1925-52), 133 cfs; median of yearly mean discharges, 53 cfs.

Extremes. Maximum discharge during year, 39,000 cfs Jan. 16 (gage height, 17.6 ft), from 

rating curve extended above 9,200 cfs on basis of float measurements at gage heights 

9.88, 12.42, and 17.6 ft; no flow Oct. 1 to Dec. 29, Jan. 1-6, 8-11.

1908-18, 1925-52: Maximum discharge,.45,000 cfs Mar. 3, 1938 (gage height, 29.3 ft,, 

site and datum then in use), from rating curve extended above float measurement of 

38,000 cfs by logarithmic plotting; no flow at times in some years.

Maximum daily discharge, estimated as 62,000 cfs, occurred Jan. 9, 1907.

Remarks. Records good except those for periods of no gage-height record, which are fair. 

Discharge measurements generally made twice a month. Flow regulated by Jameson Lake 

and Gibraltar Reservoir (see pp. 150,15l). Water diverted out of basin from these reservoirs to cities of Montecito and Santa Barbara for municipal supply. Some water 

pumped from wells along river banks for irrigation.

Cooperation. Twenty-five discharge measurements furnished by Bureau of Reclamation and 

13 by Corps of Engineers.

Revisions (water years). W 611: Drainage area. W 931: 1914-40(M). W 981: 1938(M) .

7 miles south of San Jose.

Drainage area.--229 sq ml.

Records available.--October 1916 to September 1952.

Gage. Water-stage recorder and concrete control. Altitude of gage is 190 ft (from topographic map). Prior to Dec. 14, 1934, staff gage at site 250 ft upstream at same 

datum.

Extremes. Maximum discharge during year, 768 cfs Jan. 12 (gage height, 4.77 ft, backwater 

from debris); no flow for several periods.

1916-52: Maximum discharge, 10,000 cfs Feb. 10, 1922 (gage height, 12.8 ft, from 

floodmarks), from rating curve extended above 4,900 cfs parallel to 1917 curve defined 

by current-meter measurements to 8,400 cfs; no flow at times during each year.

Remarks.--Records good except those for period of no gage-height record and those above 

30 cfs, which are poor. Water pumped from wells along creek above station for irrigation. Flow regulated by Coyote Reservoir beginning in 1936 (capacity, 24,560 acreft), by Anderson Reservoir beginning in 1950 (capacity, 75,000 acre-ft), and by detention in percolating reservoir 6 miles above station; water released during summer.

Gage. Staff gage read once or twice daily. Datum of gage is 2,535.0 ft above mean sea 

level (levels by Corps of Engineers). Prior to Mar. 11, 1952, water-stage recorder at 

site 0.6 mile upstream at different datum.

Average discharge.--? years (1945-52), 461 cfs.

Extremes . Maximum daily discharge during year, 8,000 cfs May 30; minimum, 2,1 cfs Nov. 27. 

 T545-52: Maximum discharge, 39,000 cfs Nov. 19, 1950 (gage height, 23.4 ft, site and

datum then in use), from rating curve extended above 1,100 cfs on basis of slope-area

determination of peak flow; minimum, that of Nov. 27, 1951.

Remarks . Records good except those for which observed gage height is not representative 

of mean_and for periods of no gage-height record, which are fair. Borel Canal (see 

p. 218) diverts 5 miles above the station; many 'diversions above station for irrigation.

Discharge, In cubic feet per second, water year October 1951 to September 1952

 22 E., at south end of El Rico Ranch Bridge across Tule River and 6 miles southwest of 

Corcoran.

Records available. March 1906 to September 1920 (incomplete), February 1937 to September 

1952.

Gage.--Staff gage read at various times. Elevations interpolated for days of no gage-

 height record. Datum of gage is at mean sea level. March 1906 to September 1920, 

1937-50, water-stage recorder or staff gage at various sites. Staff gages at various 

sites and at different datums.

Extremes --Maximum elevation observed during year, 195.15 ft June 2, lake dry Oct. 1 to

1906-52: Maximum elevation, 196.8 ft June 27, 28, 1941; lake dry or practically so 

during parts of 1906, 1914, 1915-16, 1919, 1937, 1946, 1950-52; lake dry during entire 

years 1920-22, 1924-36, 1947-49.

Average discharge.--11 years (1941-52), 582 cfs; median of mean yearly discharges, 480 cfs.

Extremes. Maximum discharge during year, 11,100 cfs Apr. 6 (gage height, 10.54 ft), from 

rating curve extended above 6,000 cfs; minimum daily, 57 cfs Oct. 1, 8, 13-22.

1940-52: Maximum discharge, 13,300 cfs Nov. 21, 1950 (gage height, 12.25 ft), from 

rating curve extended above 2,300 cfs on basis of a previous curve defined to 8,700 cfs; 

minimum, 32 cfs Sept. 5, 6, 1949.

Maximum stage known, 13.2 ft from floodmarks, probably in February 1940 (discharge, 

13,300 cfs, from rating curve extended above 9,000 cfs).

Remarks.--Records good except those for periods of no gage-height record or once-daily 

staff-gage readings and those above 5,000 cfs, which are poor. Flow slightly regulated 

by millpond at Sloat. Diversions for irrigation of about 41,000 acres above station.

North Fork Feather River near Prattville, Calif.

Location. Lat 40°10', long. 121° 06", in SW£ sec. 28, T. 27 N., R. 8 E., on left bank 0.5

mile downstream from Almanor Dam, 5 miles southeast of Prattville, and 9 miles upstream

from Butt Creek. 

Drainage area.--507 sq mi. 

Hecords available. June 1905 to September 1952 (tables of daily discharge for July 1921

to September 1936 include water diverted through Almanor-Butt Creek tunnel). 

Gage.--Water-stage recorder with compound rectangular concrete weir. Altitude of gage is

4",380 ft (from topographic map). Prior to Oct. 1, 1936, staff gages or water-stage

recorders at several sites within half a mile of present site, at various daturas. 

Average discharge. 46 years (1905-10, 1911-52), 881 cfs, including diversion through

Aimanor-Butt Creek tunnel. 

Extremes. Maximum discharge during year, 2,550 cfs Feb. 5 (gage height, 6.74 ft); minimum,

11 cfs Nov. 24-30. Extremes do not include diversions through Almanor-Butt Creek

tunnel. 

1905-52: Maximum discharge, 10,000 ofs Mar. 19, 1907, before construction of dam

(gage height, 16.2 ft, at former site), from rating curve extended above 3,700 cfs; no

flow Apr. 15, 16, 1914, at times during January to April 1919, and Apr. 21, 1923. 

Remarks. Records good. Flow regulated by Lake Almanor beginning in 1913 (see preceding

page). Water is diverted for power from Lake Almanor through Almanor-Butt Creek tunnel to

Butt Creek. Figures of monthly discharge show total runoff. 

Cooperation.--Water-stage recorder graph and one discharge measurement furnished by

Pacific Gas & Electric Co., obtained in connection with a Federal Power Commission

project. 

Correction. Corrected figures of mean discharge and runoff in acre-feet for water year

1951, superseding fugures published in Water-Supply Paper 1215, are given herewith:

SACRAMENTO RIVER BASIN 425

Bowman Lake near Graniteville, Calif.

Location. Lat 39°27', long. 120°39', in SW^ sec. 5, T. 18 N., R. 12 E., on rock-fill

 portion of Bowman Dam on Canyon Creek, 4 miles east of Graniteville, and 8 miles south

of Sierra City.

Drainage area.--30 sq mi, approximately. 

Records available. December 1926 to September 1952. 

Gage. Staff gage read at odd times. Datum of gage is 5,000.0 ft above mean sea level

 (levels by Nevada Irrigation District). Gage readings have been reduced to elevations

above sea level. 

Extremes. Maximum contents observed during year, 69,800 acre-ft July 17-19 (elevation,

 5,565.0 ft); minimum observed, 24,800 acre-ft Jan. 10 (elevation, 5,501.4 ft).

1926-52- Maximum contents observed, 70,500 acre-ft one or more days in 1937, 1943, 

1950, and 1951 (elevation, 5,565.9 ft); no contents Nov. 25 to Dec. 9, 1949. 

Remarks --Lake is formed by one rock-fill and one concrete-arch dam; completed and storage

 began in November 1926. Capacity, 68,200 acre-ft between elevations 5,400 ft (bottom 

of outlet tunnel) and 5,563 ft (crest of concrete-arch dam) above mean sea level. 

Flashboards are occasionally added, increasing elevation to 5,564.5 ft and capacity to 

69,400 acre-ft. Lake recieves water from Middle Yuba River through Milton-Bowman 

tunnel (see p. ), and releases it through Bowman-Spaulding Canal (see following 

page) which conveys it to reservoirs of Pacific Gas & Electric Co. Water is eventually 

used for irrigation by Nevada Irrigation District. Record shows total contents, all of 

which are available for release.

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

SACRAMENTO RIVER BASIN 435 

Bear River near Coifax, Calif.

Location.--Lat 39°07'45", long. 120°57'35" in NW£ see. 27, T. 15 N., R. 9 E., on right bank 

0.2 mile downstream from Colfax-Grass Valley highway bridge, 1.4 miles downstream from 

Greenhorn Creek, and 2 miles north of Coifax.

Drainage area. 105 sq mi.

Records available.--November 1911 to June 1917, November 1949 to September 1952.

Gage. Water-stage recorder and concrete control. Altitude of gage is 1,900 ft (from topographic map). Prior to Aug. 8, 1915, staff gages at several sites just above diversion dam 0.5 mile upstream at different datum. Aug. 8, 1915, to June 30, 1917, staff 

gage 0.2 mile downstream at different datum.

Extremes. Maximum discharge during year, 7,790 cfs Feb. 1 (gage height, 19.81 ft), from 

rating curve extended above 3,600 cfs on basis of slope-area determination at gageheight 21.40 ft; no flow at times July, August, and September.

1911-17, 1949-52: Maximum discharge, 9,620 cfs Nov. 20, 1950 (gage height, 21.40 

ft), from rating curve extended above 3,600 cfs on basis of slope-area determination of 

peak flow; no flow at times 1912-13, 1952.

Yuba River and North Fork American River by way of Drum and Alta powerplants. Storage 

and diversions above station for irrigation and power. (See records for Bear River 

Canal, p. 434, which diverts 0.5 mile above station.)

440 SACRAMENTO RIVER BASIN

Sacramento River at Verona, Calif.

Location.--Lat 38°46'50", long. 121 "36'15", in SE^- sec. 23, T. UN., R. 3 E., on left bank 

0.8 mile southeast of Verona, 1 mile downstream from Feather River, 6.2 miles east of 

Knights Landing, and at mile 19.6 upstream from Sacramento.

Records available. May 1926 to September 1952 (1926-29, low-water periods only) in reports 

ol1 Geological Survey. 1926-52 (1926-29, gage heights only) in reports of Division of 

Water Resources, Department of Public Works, State of California.

Gage. Water-stage recorder. Datum of gage is 0.06 ft below datum of Corps of Engineers. 

Auxiliary water-stage recorder 16 miles downstream from base gage since Oct. 1, 1944. 

Prior to Oct. 1, 1944, auxiliary water-stage recorder at site 19.2 miles downstream.

Average discharge.--23 years (1929-52), 17,330 cfs.

Extremes --Maximum discharge during year, 61,800 cfs Feb. 4; maximum gage height, 35.83 ft 

Jan. 16; minimum discharge, 7,110 cfs Oct. 23.

1926-52: Maximum discharge, 79,200 cfs Mar. 1, 1940 (gage height, 41.20 ft); minimum daily, 304 cfs July 23, 24 1931; maximum reverse flow, 16,800 cfs Dec. 4, 1950 

(backwater from American River).

1934-52: Maximum combined discharge of Sacramento River at Verona and Fremont weir, 

about 315,000 cfs Mar. 1, 1940.

Remarks. Records excellent. Reservoirs, many diversions, and considerable return water 

affect flow. When discharge exceeds about 55,000 cfs, flow begins over Fremont weir 

(Just upstream) into Yolo bypass (see p. 472). Elevation of crest of Fremont weir is 

33.5 ft (datum of Corps of Engineers).

Discharge, In cubic feet per second, water year October 1951 to September 1952

Location. Lat 38°46', long. 120°42', in SW£ sec. 25, T. 11 N., R. 11 E. , on right bank 

SOtTTt upstream from Iowa Canyon Creek, 1 mile downstream from intake of American River 

flume, and 3 miles northwest of Camino.

Drainage area.--497 sq mi.

Records available. October 1922 to September 1952.

Gage. Water-stage recorder. Altitude of gage is 1,640 ft (from topographic map). Prior 

to Oct. 31, 1950, water-stage recorder at same site and datum. Nov. 1, 1950, to Dec. 5, 

1951, staff gage read twice daily at present site and datum.

Average discharge. 30 years, 948 cfs, combined flow of South Fork American River near 

Camino and American River flume.

Extremes. Maximum discharge during year, 9,420 cfs May 28 (gage height, 13.20 ft); minimum, 

21 cfs Sept. 9, 19.

1922-52: Maximum discharge, 46,000 cfs Nov. 21, 1950 (gage height, 29.4 ft, from 

floodmarks), from rating curve extended above 24,000 cfs on basis of flow at upstream 

and downstream stations; minimum, 1.2 cfs Aug. 24, 1931.

Remarks.--Records fair prior to Dec. 6, good thereafter. Flow partly regulated by four 

reservoirs since beginning of record (total usable capacity now 35,500 acre-ft). Two 

diversions above station; American River flume (see p. 459) and El Dorado Canal (see 

p. 453). Water from El Dorado Canal is returned to river above gage.

Cooperation.--Water-stage recorder graph and three discharge measurements furnished by 

Pacific Gas & Electric Co., in connection with a Federal Power Commission project.

Revisions (water years).--W 931: 1928, 1938, 1940(M).

515 LOST RIVER BASIN 

Lost River diversion canal near Olene, Oreg.

Location. Lat 42°09' , long. 121°40, in Slrf£ sec. 29, T. 39 S., R. 10 E., on left bank 

4 miles southwest of Olene.

Records available. May 1912 to September 1952.

Gage. Staff gages above and below headgates at intake of canal at Lost River Dam, read 

once daily.

Average discharge. 36 years (1912-15, 1919-52), 131 cfs.

Extremes. 1912-52: Maximum daily discharge, 2,260 cfs Mar. 30, 1952; no flow at times.

Remarks. Records fair. Discharge computed from daily record of openings and head-on 

gates with variable coefficient determined by discharge measurements. Canal diverts 

water from Lost River and except for amounts pumped, as shown below, this water is discharged into Klamath River to aid in reclamation of bed of Tule Lake. Discharge includes water occasionally wasted from "C" Canal flume below intake. Beginning in July 

1951 records include pumpage by Miller Hill pumping plant which operates at times; 

during May through September 1952, pumpage amounted to 4,820 acre-ft. At times direction of flow is reversed and water diverted from Klamath River into Lost River. (See 

record for Diversion from Klamath River to Lost River near Olene.)

Cooperation.--Records furnished by Bureau of Reclamation.

516 LOST RIVER BASIN

Diversion from Klamath River to Lost River, near Olene, Oreg.

Location. Lat 42°09' , long. 121°42', in SW£ sec. 30, T. 39 S., R. 10 E., on right bank 

5 miles southwest of Olene.

Records available. April 1931, when diversion began, to September 1952.

Gage. Staff gage above rectangular gate at wasteway read once daily.

Average discharge. 22 years, 35.9 cfs.

Extremes. 1931-52: Maximum daily discharge, 719 cfs Apr. 15, 1951; no flow at times.

Remarks. Records fair. Discharge computed from daily record of gate openings and gage 

readings at wasteway with coefficients applied based on discharge measurements. Canal 

was built to divert water from Lost River to Klamath River and thereby aid in reclamation 

of bed of Tule Lake. (See record for Lost River diversion canal near Olene.) Beginning in April 1931, water has been diverted at times from Klamath River and released 

into drain which empties into Lost River, from which it is rediverted for irrigation of 

lands near Tule Lake. Beginning In June 1949, records include pumpage by Miller Hill 

pumping plant, which operates at times; during May through August 1952, pumpage amounted 

to 4,200 acre-ft.

Cooperation. Records furnished by Bureau of Reclamation.
