SURFACE WATER SUPPLY OP PACIFIC SLOPE BASINS IN CALIFORNIA, 1959

SCOPE OF WORK

This volume is one of a series of 20 reports presenting records of stage, discharge, 

and content of streams, lakes, and reservoirs in the United States during the 1959 water 

year. Since 1888, when the United States Geological Survey first studied streamflow in 

relation to problems of irrigation, similar records have been obtained at more than 

15,200 gaging stations in the 50 States. On September 30, 1959, the Geological Survey 

and cooperating organizations were maintaining 7,110 gaging stations. Partial-recorci 

stations for low flow or for flood flow have been operated at many other points. In 

addition, discharge measurements are made at miscellaneous sites. The records for the 

1959 water year at gaging stations, partial-record stations, and miscellaneous sites in 

the Pacific slope basins in California are given in this report.

COOPERATION

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

of Water Resources, H. 0. Banks, director; Alameda County Water District; Contra Costa 

County Flood Control and Water Conservation District; Montecito County Water District; 

Santa Clara County Flood Control and Water Conservation District; Orange County Flood Control District; Sacramento Municipal Utility District; San Bernardino Valley Water Conservation District; San Luis Obispo County Flood Control and Water Conservation District; 

Santa Barbara County Water Agency; Santa Cruz County Flood Control and Water Conservation 

District; San Benito County; and cities of Arcata, San Diego, and Santa Barbara. In 

Oregon the work was done under cooperative agreement with the State of Oregon, L. A. 

Stanley, 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 55 gaging stations, 

by the United States Navy for 9 gaging stations, by the Bureau of Reclamation, United 

States Department of the Interior, for 44 gaging stations, and by the Soil Conservation 

Service, United States Department of Agriculture, for 2 gaging stations. 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 and individuals aided in collecting records: In California, 

The California Oregon Power Co.; California Water and Telephone Co.; Francis N. Dlouhy; 

East Bay Municipal Utility District; The Irvine Ranch; Kings River Water Association; 

Pauba Ranch; Pacific Gas & Electric Co.; San Bernardino County Flood Control District; 

Southern California Edison Co.; United Water Conservation District; Ventura County Water 

Resources Division; and Helix, Madera, Merced, Modesto, Nevada, Serrano and Carpenter, 

Turlock, Oakdale, Oroville-Wyandotte, South San Joaquin, Vista, and Woodbridge Irrigation Districts; in Oregon, The California Oregon Power Co.
2 'SURFACE WATER SUPPLY, 1959, PART 11

DIVISION OF WORK

The stream gaging work was done by the Water Resources Division of the Geological Survey under the direction of personnel shown in the preface. The data for stations in the 

States of California and Oregon were collected and prepared for publication in the district offices listed below.

State District office Address

California.............. Menlo Park.................. 345 Middlefield Road.

Oregon a/............... Portland.................... 1001 HE. Lloyd Boulevard.

a/ The work was done in collaboration with L. A. Stanley, State engineer.

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. Some gagingstation records for California have been analyzed by electronic computer to give (1) 

the number,of days in each year that the daily discharge was "between selected limits (duration tables); (2) the lowest mean discharge for periods of 7, 15, 30, 60, 120 and 183 

consecutive days in each year; and (3) the highest mean discharge for periods of 3, 7, 15, 

30, and 120 consecutive days in each year. Provisional records of discharge, information 

on the availability of electronic computer results, and other unpublished data concerning 

the gaging-station records may generally be obtained from the district offices.

DEFINITION OF TERMS AND ABBREVIATIONS

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

as follows:

Gaging station is a particular site on a stream, canal, lake, or reservoir where systematic observations of gage height or discharge are obtained. When used in connection 

with- a discharge record, the term is applied herein only to those gaging stations where 

a continuous record of discharge is obtained.

Partial-record station is a particular site where limited streamflow data are collected 

systematically over a period of years for use in hydrologic analyses.

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.

Cubio 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 (in.) shows the depth to which the drainage area would be covered if 

all the runoff for a given time period were uniformly distributed on it.

Acre-foot (ac-ft) is the quantity of water required to cover an acre to the depth of 

1 foot and is equivalent to 43,560 cubic feet.

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.
EXPLANATION OF DATA 3

Control designates a feature downstream from the gage that determines the stagedischarge 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.

WSP is used as an abbreviation for "Water-Supply Paper" in references to previously 

published reports.

DOWNSTREAM ORDER AND STATION NUMBERS

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.

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.

As an added means of identification, each gaging station and partial-record station 

has been assigned a station number. The numbers have been assigned in the same downstream 

order used in this report. In assigning station numbers, no distinction is made between 

partial-record stations and regular gaging stations, so that the station number for a 

partial-record station indicates downstream-order position in a list made up of both types 

of stations. Gaps are left in the numbers to allow for new stations that may be established; hence the numbers are not consecutive. The complete number for each station 

includes the part number, but the station number shown in this report, Just to the left 

of the station name, consists of only the essential digits of the complete number. For 

example, for a station with the complete number 11-0100.00, the station number shown in 

this report is 100. The notation to the left of the hyphen is the part number; it is 11 

for all stations in this report and is therefore omitted.

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
4 SURFACE WATER SUPPLY, 1959, PART 11

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.

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 gage 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 in 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.

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 of 

the stream. Records~are published for the water year which begins on October 1 and ends 

on September 30. A calendar for the water year 1959 is shown on page IV for the purpose 

of finding the day of the week for any date.

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
EXPLANATION OF DATA 5

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 "Records available" are given the 

periods for which there are published records generally equivalent to those at the present site. Under "Gage" are given the type of gage currently in use s_nd_ the datum of the 

present gage above mean sea level, and a condensed history of the types, locations, and 

datums of previous gages used during the period of records available. 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). In the first paragraph, the data given are for the complete current water year unless otherwise specified. In the second paragraph, the data 

given are for the periods of record within the calendar year dates in the heading (not 

necessarily those for the complete years indicated by the heading dates). Reliable information concerning major floods that have occurred outside the period of record are given 

in the third or last paragraph under "Extremes." 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 

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 shifting-
6 SURFACE WATER SUPPLY, 1959, PART 11

control method, the slope method, or other special methods involving an equivalent adjustment to the gage height of more than one-tenth foot. Skeleton rating tables are generally 

not published for stations on canals.

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 figures for the maximum day and the minimum day 

for each month are underlined. If the figure 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 figures; 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. Discharge 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"). Figures 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 figures 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 discharge.

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
ACCURACY OF FIELD DATA AND COMPUTED RESULTS 7

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.

At many gaging stations water samples are collected from the streams for the purpose of 

making chemical analyses, computing dissolved solidg, suspended sediment loads, and 

particle-size distribution, or measuring water temperatures. For most of these samples 

the results are published in an annual series of water-supply papers entitled "Quality of 

Surface Waters of the United States" which is issued in four volumes. In this report, 

under "Remarks" a reference is made to quality-of-water records collected at gagingstations on a regular basis and published in the quality-of-water reports. At many other 

gaging stations quality-of-watsr data are obtained at irregular intervals and published as 

"miscellaneous analyses" in quality-of-water reports; such records are not referred to in 

"Remarks" paragraph in this report. At many gaging stations water temperature is obtained 

also at the time a discharge measurement is made; such temperature readings are not 

reported in the quality-of-water annual reports.

Data collected at partial-record stations and at miscellaneous sites are given at the 

end of each report. Partial-record stations are presented in two tables. The first is 

a table of discharge measurements at low-flow partial-record stations, and the second is 

a table of annual maximum stage and discharge at crest-stage stations. Discharge measurements at miscellaneous sites are given in a third table. Occasionally, a series of 

discharge measurements are made within a short time period to investigate the seepage 

gains or losses along a reach of a stream or to determine the low-flow characteristics 

of an area. Such measurements are given In special tables after the list of measurements at miscellaneous sites.

ACCURACY OF 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.

Discharge 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, 

figures of cubic feet per second per square mile and of runoff in inches are not published unless satisfactory adjustments can be made for diversions, 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.
8 SURFACE WATER SUPPLY, 1959, PART 11

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

Basic data for gaging stations are published in an annual series of reports consisting 

of 20 volumes, including one each for the States of Alaska and Hawaii. The area of the 

other 48 States is divided into 14 parts whose boundaries coincide, with certain natural 

drainage lines. Formerly, the annual series of reports on surface-water supply consisted 

of 14 volumes, one for each of the 14 parts. Beginning with the reports for 1951, the 

records for the 48 States were 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 1.

HYDROLOGIC CONDITIONS

The 1959 water year was generally one of the driest years of record in the area covered 

by this report. As a result, runoff was deficient in all areas except the extreme northwest where streamflow was normal. In the north coastal area runoff was about 80 percent 

of normal, in the Central Valley about 60 percent of normal, and in the central and south 

coastal areas about 30 percent of normal. The water year was climaxed by the heaviest 

general September storm since 1904. Associated with this general storm was localized highintensity rainfall that caused damaging flash floods in and near the city of Redding in 

the upper Sacramento River basin.

Figure 2 on page 14, for which records of three long-term gaging stations were used, 

shows a comparison of the monthly and yearly mean discharges for the 1959 water year with 

the median discharge for the period 1921-45.

outlet tower.

Drainage area.--120 sq mi, approximately.

Records available.--January 1916, October 1936 to September 1959.

Gage.--Staff gage read once daily. Datum of gage is 2,882.4 ft above mean sea level.

Average discharge. 23 years (1936-59), 13.3 cfs (9,630 acre-ft per year); median of 

yearly mean discharges, 6.6 cfs (4,800 acre-ft per year).

Remarks.--Records of runoff represent all water reaching Morena Reservoir, including precipitation on reservoir surface. Runoff computed on basis of records of storage, 

release (draft), spill, leakage, and evaporation. Monthly evaporation from reservoir 

surface computed on basis of evaporation from Colorado pan using a coefficient of 0.80. 

Capacity and area ratings for reservoir are based on a resurvey made in 1948. Capacity 

of reservoir at permanent spillway level (gage height, 157.00 ft), 50,210 acre-ft. 

Dead storage, 654 acre-ft below outlet No. 3 at gage height 70.5 ft. No diversion above 

reservoir. Water is released down Cottonwood Creek to Barrett Reservoir as required.

Cooperation.--Records computed in cooperation with city of San Diego.

Note. For months when inflow to the reservoir was small and other quantities were large, discordant figures of runoff may appear. This arises primarily from the difficulty of computing runoff as the residual of several larger quantities, which are not susceptible to measurement with a 

precision necessary to produce a final answer within desirable limits of accuracy.

December 1915. October 1936 to September 1946 published as "near Dulzura";i records not 

equivalent, as they were computed to represent runoff from Cottonwaod Creek basin below 

Morena Dam (drainage area, 130 sq mi).

Gage. Staff gage read once daily. Datum of gage is 1,446.12 ft above mean sea level. 

January 1906 to December 1915, staff gage at same site at different datum (prior to 

completion of dam).

Remarks. Records of inflow represent all water reaching Barrett Reservoir, including precipitation on the reservoir and water passing down Cottonwood Creek from Morena Reservoir. Inflow computed on basis of records of storage, release (draft), spill, leakage, 

and evaporation. Monthly evaporation from reservoir surface computed on basis of evaporation from Colorado pan using a coefficient of 0.80. Capacity and area ratings for 

reservoir are based on a resurvey made in 1948, 1951, and 1955. Capacity of reservoir 

at top of flash gates on spillway (gage height, 168.88 ft), 44,760 acre-ft. Dead storage, 719 acre-ft below lowest outlet at gage height 58.8 ft, included in these records. 

Flow partly regulated by Morena Reservoir (see p. 15 ). Water drawn from Barrett Reservoir is diverted out of drainage basin to Lower Otay Reservoir by Dulzura conduit for 

municipal use.

Note. For months when inflow to the lake was small and other quantities were large, discordant 

figures of runoff may appear. This arises primarily from the difficulty of computing runoff as the 

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

necessary to produce a final answer within desirable limits of accuracy.

240. Santa Ysabel Creek at Sutherland Dam, Calif.

Location.--Lat 33°07'05", long 116°47'10", in NW£NW£SW£ sec.21, T.12 S., R.2 E., on face 

of Sutherland Dam, 1.6 miles upstream from Black Canyon Creek and 7 miles northeast of 

Ramona.

Drainage area. 57 sq mi, approximately.

Records available. December 1912 to September 1928, October 1936 to September 1959. 

Prior to October 1953, published as "near Mesa Grande."

Gage. Water-stage recorder. Datum of gage is 1,912.00 ft above mean sea level (levels 

by city of San Diego). Prior to Oct. 1, 1936, water-stage recorder at same site at 

various datums. Oct. 1, 1936, to Sept. 30, 1953 water-stage recorder at site 1 mile 

downstream at different datum. Mar. 7 to Nov. 29, 1954, staff gage at present site 

and datum.

Average discharge.--38 years (1913-28, 1936-59), 20.4 cfs (14,770 acre-ft per year); 

median of yearly mean discharges, 12 cfs (8,500 acre-ft per year).

Remarks. Records of runoff represent all water reaching Sutherland Reservoir including 

precipitation on reservoir. Runoff computed on basis of records of storage, release 

(draft), spill, leakage, and evaporation. Monthly evaporation from lake surface 

computed on basis of evaporation from Colorado pan using coefficient of 0.80. Capacity and area ratings for the reservoir are based on an aerial survey made in 1949. 

Capacity of reservoir at spillway level (gage height, 145.00 ft), 29,680 acre-ft. 

Dead storage, 176 acre-ft below lowest outlet at gage height 28.00 ft, included in 

these records. Small diversion above reservoir. Water is released as required for 

municipal use.

Cooperation.--Records computed in cooperation with city of San Diego.

Note. For months when Inflow to the reservoir was small and other quantities were large, discordant figures of runoff may appear. This arises primarily from the difficulty of computing 

runoff as the residual of several larger quantities, which are not susceptible to measurement 

with a precision necessary to produce a final answer within desirable limits of accuracy.

SAN DIEGUITO 'RIVER BASIN 35

290. San Dieguito River near San Pasqual, Calif.

Location. La t 33°04 I 00", long 117 "02'OS", in San Bernardo Grant, on right bank 1.5 miles 

downstream from Bach Creek, 4.5 miles southeast of Escondido, and 5 miles west of San 

Pasqual, San Diego County.

Drainage area. 250 sq mi, approximately.

Records available. April 1947 to April 1956 (irrigation seasons only), May 1956 to September 1959.

Gage. Water-stage recorder. Altitude of gage is 325 ft (from topographic map).

Extremes.--Ho flow during year.

T356-59: Maximum discharge, about 3,600 cfs Apr. 3, 1958 (gage height, 7.35 ft), 

from field estimate of peak flow; no flow during most months of each year.

Remarks. No flow since May 14, 1958. Diversions for irrigation and pumping from wells 

along river in San Pasqual Valley above station. Flow regulated since July 1954 by 

Sutherland Reservoir (see p. 30). Figures for the calendar year 1958 are as follows: 

maximum daily discharge, 1,170 cfs; minimum daily, zero; mean, 20.0 cfs; runoff, 

14,500 acre-ft.

300. San Dieguito River at Lake Hodges, Calif.

Location. Lat 33°02 1 48", long 117°07'33", in NE^SE^NW^ sec. 18, T.13 S. , R.2 W., on right 

bank 800 ft upstream from Lake Hodges Dam and 6.2 miles southwest of Escondido.

Drainage area.--303 sq mi.

Records available. January 1916 to September 1959. Published as "near Bernardo" prior 

to October 1920 and as ''near Escondido" October 1920 to September 1925.

Gage.--Staff gage read once daily. Datum of gage is 200.0 ft above mean sea level. Prior 

to January 1919, staff gage at same site at different datum (prior to completion of 

dam).

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

precipitation on the lake and supplemental water from Colorado River delivered through 

aqueduct of San Diego County Water Authority. Total inflow computed on basis of 

records of storage, release (draft), spill, leakage, and evaporation. Records of net 

inflow exclude supplemental water from Colorado River. Capacity and area ratings for 

lake are based on a resurvey in 1948. Monthly evaporation from lake surface computed 

on basis of evaporation from Colorado pan using coefficient of 0.80. Capacity of lake 

at spillway level (gage height, 115.00 ft), 33,550 acre-ft. Dead storage, 1,160 acre-ft 

below lowest outlet at gage height 54.0 ft, included in these records. Water drawn 

from Lake Hodges passes through a conduit to San Dieguito reregulating reservoir, from 

which it is released as required for municipal use. Diversions for irrigation above 

Lake Hodges. Flow regulated since July 1954 by Sutherland Reservoir (see p. 30).

Cooperation.--Records computed in cooperation with city of San Diego.

Note. For months when inflow to the lake was small and other quantities were large, discorda 

figures of net inflow may appear. This arises primarily from the difficulty of computing net i 

as the residual of several larger quantities which are not susceptible to measurement with a pr 

sion necessary to produce a final answer within desirable limits of accuracy.

SAN LUIS KEY RIVER BASIN 37

350. San Luis Rey River at Lake Henshaw, near Mesa Grande, Calif.

Location. Lat 33°14'20", long 116°45'43", in Valle de San Jose Grant, at Henshaw Dam, 

4 miles north of Mesa Grande, San Diego County.

Drainage area. 209 sq mi.

Records available. January 1923 to September 1959. October 1911 to January 1923 at site 

1 mile downstream published as "near Mesa Grande"; records not equivalent due to change 

in natural water losses resulting from creation of Lake Henshaw.

Gage. Staff gage read once daily. Datum of gage is 2,620 ft above mean sea level. Prior 

fo June 14, 1912, staff gage at same site at different datum. June 14, 1912, to January 1923, water-stage recorder at site 1 mile downstream at different datum.

Average discharge. 11 years (1911-22), 59.6 cfs (43,160 acre-ft per year), below damsite; 

37 years (1922-59), 29.0 cfs (20,980 acre-ft per year), discharge at Lake Henshaw, 

exclusive of 90 percent of precipitation on lake surface; median of yearly mean discharges, 18 cfs (13,000 acre-ft per year).

Remarks.--Records of net 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 lake bed. Net runoff computed on basis of records of storage, release (draft), spill, leakage, evaporation, precipitation, and ground-water 

pumpage. Monthly evaporation from lake surface computed on basis of evaporation from 

a floating pan using a coefficient of 0.87, except during periods when winds swamp the 

floating pan. Net evaporation for these periods is computed on basis of Colorado pan 

using coefficient of 0.80. Capacity and area ratings for lake are based on resurvey 

made in October 1951. Capacity of lake 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 

year the amount of precipitation excluded was 1,228 acre-ft. No flow over spillway 

since dam was completed. Water is released down San Luis Rey River for diversion

Note. For months when Inflow to the lake was small and other quantities were large, discordant 

figures of net runoff may appear. This arises primarily from the difficulty of computing net 

runoff as the residual of several larger quantities, which are not susceptible to measurement 

with a precision necessary to produce a final answer within desirable limits of accuracy.

About 4,000 cfs, result of failure of temporary dam. 

tt From floodmark.

1946-59: Maximum discharge, 4,650 cfs Apr. 1, 1958 (gage height, 5.62 ft); no flow 

for all or several months each year.

Remarks.--Records fair except those above 10 cfs and those for periods of no gage-height 

record, which are poor. Minor flows regulated by percolation basins.

Cooperation.--Gage-height record and 58 discharge measurements for water years 1947-55 

furnished by the U. S. Navy.

Discharge, in cubic feet per second, water year October 1946 to September 1947

550. Mill Creek near Mentone, Calif.

Location. Lat 34°05'14", long 117°06<46", in NE£SEjNW£ sec.17, T.I S., R.2 W. , on

downstream side of right pier of Bear Valley Mutual Water Co.'s pipeline crossing,

0.4 mile upstream from mouth and 1.6 miles northeast of Mentone. 

Drainage area. 51.7 sq mi.

Records available. February 1939 to September 1959. 

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

topographic map). 

Average discharge. 20 years, 3.34 cfs (2,420 acre-ft per year); median of yearly mean

discharges, 0.6 cfs (430 acre-ft per year). 

Extremes.--Maximum discharge during year, 315 cfs Feb. 16 (gage height, 5.10 ft); no

flow for most days.

1939-59: Maximum discharge, 1,500 cfs Dec. 23, 1945 (gage height, 6.5 ft), on

basis of slope-area measurement of peak flow; no flow for parts of each year. 

Revisions. The figures of maximum discharge for some water years have been

revised, as shown in the following table. They supersede figures published in the

water-supply papers indicated.

Remarks.--Records good. Discharge measurements or observations of no flow generally 

made two or more times a month. The Zanja and Mill Creek spreading grounds divert 

most of low-water flow above station. Pumpage from wells along stream above station 

for irrigation affects surface flow at station.

Revisions. Revised figures of discharge, in cubic feet per second, for high-water 

period in the water year 1943, superseding those published in WSP 981, are given

102 SANTA ANA RIVER BASIN

660. Warm Creek near Colton, Calif.

Location. Lat 34°04'08", long 117°18'26", In San Bernardino Grant, on left bank 150 ft 

downstream from Colton Avenue Bridge, 0.4 mile upstream from mouth, and 0.9 mile east 

of Colton, San Bernardino County.

Drainage area. 259 sq mi.

Records available. August 1920 to September 1959.

Gage.--Water-stage recorder. Altitude of gage is 950 ft (from topographic map). Prior 

to Sept. 13, 1958, at site 150 ft upstream at different datum.

Average discharge.--39 years, 45.5 cfs (32,940 acre-ft per year); median of yearly mean 

discharges, 40 cfs (29,000 acre-ft per year). Average combined discharge of Warm 

Creek and Weeks & Daley Canal, 39 years, 56.8 cfs (41,120 acre-ft per year); median 

of yearly mean combined discharges, 52 cfs (37,600 acre-ft per year).

Extremes. Maximum discharge during year, 990 cfs Jan. 6 (gage height, 4.75 ft); minimum 

daily, 2.1 cfs Sept. 20.

1920-59: Maximum discharge, 27,500 cfs Mar. 2, 1938 (gage height, 11.2 ft, datum 

then in use), on basis of slope-area measurement of peak flow; minimum, 1.4 cfs 

July 17, 1951 (gage height, 0.71 ft, datum then in use). Maximum discharge including 

west channel of Lytle Creek, 35,000 cfs Mar. 2, 1938.

Remarks. Records poor. Discharge measurements generally made three or more times a month. 

For records of combined discharge of Warm Creek and Meeks & Daley Canal, which diverts 

above station for irrigation, see following page. Adjusted runoff includes water 

pumped from the ground-water basin near Weeks & Daley canal gage. In seasons of highwater table, there is flow in a depression paralleling Warm Creek 500 ft east of 

station. This year there was no flow. Lytle Creek flood channel (capacity, 30,000 

cfs), completed In fall of 1945, enters Warm Creek above station and includes any 

flow which formerly might have been recorded at station on Lytle Creek (west channel).

Revisions (water years).--WSP 1061: 1944-45.

108 SANTA AHA RIVER BASIN

680. Santa Ana River at Auburndale Bridge, near Corona, Calif.

Location.--Lat 33°55'27", long 117°35'48", in La Sierra (Yorba) Grant, on right bank 

50 ft upstream from Auburndale Bridge on River Road, 1.7 miles upstream from Temescal 

Creek, and 3.8 miles northwest of Corona, Riverside County.

Drainage area. 1,021 sq mi.

Records available.--May 1930 to November 1959 (irrigation seasons only).

Gage.--Water-stage recorder. Datum of gage is 501.36 ft above mean sea level, datum of 

T929 (levels by Orange County Flood Control District). Prior to May 1946, at various 

sites within 1,000 ft of bridge and at different daturas.

Remarks.--Records good. Discharge measurements generally made four times a month. 

Flow partly regulated by Big Bear Lake (see p. 79). Natural flow is affected by 

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

areas. Water diverted into Durkee ditch, a quarter of a mile above station, bypasses 

station; discharge measurements of flow in ditch as given below.

Cooperation.--Nineteen discharge measurements furnished by Orange County Flood Control

District.

SANTA ANA RIVER BASIN

740. Santa Ana River below Prado Dam, Calif.

Location. Lat 33°53'00", long 117°38'40", in La Sierra Grant, on left bank of outlet 

channel, 2,500 ft downstream from axis of Prado Dam and 4.5 miles west of Corona, 

Riverside County.

Drainage area.--1.462 sq mi.

Records available.--May 1930 to November 1939 (irrigation seasons only), March 1940 to 

September 1959. Published as "at Santa Fe Railroad Bridge, near Prado" May 1930 to 

November 1939, and as "below Prado Dam, near Prado" March 1940 to September 1950.

Gage.--Water-stage recorder and concrete control. Datum of gage is approximately 449 ft 

above mean sea level (Corps of Engineers survey). Prior to Mar. 18, 1940, water-stage 

recorder at about same site at various daturas.

Extremes.--Maximum discharge during year, 496 cfs Jan. 6 (gage height, 3.42 ft); minimum 

daily, 17 cfs Aug. 20, 22, 23.

1940-59: Maximum discharge, 2,260 cfs Dec. 24, 1940 (gage height, 3.20 ft); minimum daily, that of Aug. 20, 22, 23, 1959.

Remarks.--Records good. Discharge measurements generally made three or more times a

month. Flow regulated by Prado Reservoir (capacity, 222,800 acre-ft) and Big Bear Lake 

(see p. 79). There was no Colorado River water released to the Santa Ana River during 

water year 1958-59. Natural flow of stream affected by extensive ground-water withdrawals, diversion for irrigation, and return flow from irrigated areas. Santa Ana 

River Developement Co. pumps water from wells above Prado Reservoir into a conduit 

which passes through dam and is released to river immediately downstream from gage.

Cooperation.--Nineteen discharge measurements and records of bypass flow were furnished 

by Orange County Flood Control District.

1945 to November 1951 (irrigation seasons only), May 1952 to September 1959. Published 

as "near Prado" 1919-42, 1945-50.

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

Prior to Mar. 17, 1927, at site 500 ft downstream at datum 2.39 ft higher. Mar. 17, 

1927, to Mar. 29, 1938, at site 500 ft downstream at datum 1.11 ft lower. Since 

Mar. 30, 1938, auxiliary water-stage recorder 45 ft upstream used at various times.

Extremes.--Maximum discharge during year, 505 cfs Jan. 6 (gage height, 4.23 ft): minimum 

 Sally, 20 cfs July 10.

1919-40, 1952-59: Maximum discharge, 100,000 cfs (estimated) Mar. 3, 1938 (gage

height, 17.3 ft, from floodmarks in gage well,site and datum then in use); minimum

daily, that of July 10, 1959.

Remarks.--Records poor. Discharge measurements generally made four times a month. Flow 

regulated by Prado Keservoir (capacity, 222,800 acre-ft) and Big Bear Lake (see p. 79 ). 

Normal flow is affected by ground-water withdrawals, diversions for irrigation, and 

return flow from irrigated areas.

Cooperation.--Nineteen discharge measurements furnished by Orange County Flood Control 

District.

Grant, on upstream face near left end of Santiago Dam, 0.3 mile upstream from Fremont 

Canyon and 5.7 miles southeast of Villa Park, Orange County.

Drainage area. 63.2 sq mi.

Records available.--October 1931 to September 1959.

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

Average discharge. 28 years, 17.6 cfs (12,720 acre-ft per year); median of yearly mean 

discharges, 10 cfs (7,500 acre-ft per year).

Remarks.--Records of total inflow represent all water reaching Santiago Reservoir, including precipitation on the reservoir and supplemental Colorado River water delivered 

through aqueduct of Metopolitan Water District of Southern California. Total inflow 

computed on basis of records of storage, release (draft), spill, leakage, and evaporation. Records of net inflow exclude supplemental water from Colorado River. 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. 

Minor diversions in basin above this reservoir.

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

Irrigation Districts and Irvine Co.

SAN GABRIEL RIVER BASIN

835. San Gabriel River near Azusa, Calif.

Location. Lat 34°10'11", long 117°53'16", in SW^NWiSW^ sec.13, T.I N. , R.10 W. , on right 

bank 1.1 miles downstream from Morris Dam and 2.7 miles northeast of A2usa.

Drainage area.--211 sq mi.

Records available.--May 1894 to September 1959.

Gage.--Water-stage recorder. Datum of gage is 367.59 ft above mean sea level (from Los 

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

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

2 miles downstream at different daturas. 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 dlscharge.--64 years (1895-1959), 152 cfs (110,000 acre-ft per year), adjusted 

for diversions, importations, regulation, and evaporation, in Cogswell, San Gabriel, 

and Morris Reservoirs; median of yearly mean adjusted discharges, 109 cfs (78,900 

acre-ft per year).

Extremes. Maximum discharge during year, 364 cfs Feb. 24 (gage height, 6.64 ft); no flow 

for most of year.

1894-1959: Maximum discharge, 65,700 cfs Mar. 2, 1938, by computation of peak flow 

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

Remarks.--Records good. Plow regulated by Cogswell and San Gabriel flood-control reservoirs (combined capacity, 54,500 acre-ft) and by Morris Reservoir (capacity, 35,000 

acre-ft). Azusa Canal diverts above high-water level of Morris Reservoir or from San 

Gabriel Reservoir about 5 miles above station. The Metropolitan Water District of 

Southern California reports a release of 2 acre-ft of Colorado River water into San 

Gabriel River below Morris Dam and above station during the 1958 water year. They also 

furnished records of adjusted runoff for San Gabriel River computed on basis of flow in 

river above Morris Reservoir plus 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 Co.'s canal as published from 1894 to 1933.

Gage. Water-stage recorder. Altitude of gage is 800 ft (from topographic map). Since 

June 26, 1959, supplementary water-stage recorder 300 ft downstream at different datum.

Average discharge . 42 years, 2.94 cfs (2,130 acre-ft per year); median of yearly mean 

discharges, 1.5 cfs (1,100 acre-ft per year).

Extremes. Maximum discharge during year, about 2,400 cfs Jan. 6 (gage height, 11.7 ft 

1'rom floodmarks) , on basis of field estimate of peak flow; no flow June 2 to Sept. 30.

1917-59: Maximum discharge (revised), that of Jan. 6, 1959; no flow at times each 

year.

Revisions. The maximum discharge for the water years 1925-26, published in 

WSP 611 and 631, are considered to be in error and should not be used.

Remarks. Records good prior to Jan. 6, poor thereafter. Discharge measurements or observations of no flow generally made twice a month except during the period Feb. 11 to 

May 5 when they were made 3 or more times a week. Diversion above station for irrigation of about 20 acres below station.

Cooperation.--Eight discharge measurements furnished by Los Angeles County Flood Control 

District-.

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

in water year 1925, superseding those published in WSP 611, are given herewith;

995. Sawpit Creek near Monrovia, Calif.

Location. Lat 34°10'23", long 117°59'18", in SW£SE±NWi sec. 13, T.I N., R.ll ¥., on 

left bank 0.1 mile downstream from Monrovia Creek, 0.3 mile downstream from Sawpit 

Dam, and 1.7 miles north of Monrovia.

Drainage area. 5.3 sq mi, approximately.

Records available. November 1916 to September 1959.

Gage. Water-stage recorder and broad-crested weir. Altitude of gage is 1,100 ft (from 

topographic map). Nov. 8, 1916,to Nov. 19, 1925, and Apr. 12 to Oct. 29, 1938, waterstage recorder at site 0.1 mile upstream at different datum. Nov. 20, 1925, to 

Mar. 2, 1938, water-stage recorder at site 0.1 mile downstream at different datum 

(destroyed by flood). Oct. 30, 1938, to Oct. 3, 1951, at present site at datum 

1.00 ft higher.

Average discharge.--42 years (1917-59), 1.13 cfs (SIS acre-ft per year); median of yearly 

mean discharges, 0.5 cfs (360 acre-ft per year). Average adjusted discharge, 42 years, 

2.49 cfs (1,800 acre-ft per year); median of adjusted yearly msan discharges, 1.9 cfs 

(1,400 acre-ft per year).

Extremes. Maximum discharge during year, 181 cfs Jan. 6 (gage height, 3.95 ft); no flow 

for many days.

1916-59: Maximum discharge (revised), about 1,800 cfs Mar. 2, 1938, computed on 

basis of inflow to flood-control reservoir above gage but may have been exceeded 

Apr. 7, 1926; no flow for parts of most years.

Revisions.--The maximum discharge for the water year 1926, published in WSP 631, 

has been found to be in error and should not be used.

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

Discharge measurements or observations of no flow generally made two or more times a 

month. Flow regulated by Sawpit flood-control reservoir (capacity, 320 acre-ft) since 

June 1927. Figures of daily discharge do not include water diverted above station by 

city of Monrovia from Monrovia Creek.

Cooperation.--Nineteen discharge measurements furnished by Los Angeles County Flood Control District.

Discharge, in cubic feet per second, water year October 1958 to September 1959

1210. Santa Ynez River at Jameson Lake, near Montecito, Calif.

Location.--Lat 34°29'32", long 119°30'25", on upstream side of Juncal Dam, 6.5 miles 

north of Carpinteria and 8 miles northeast of Montecito, Santa Barbara County.

Drainage area. 13.8 sq mi (not including Alder Creek).

Records available. December 1930 to September 1959. Prior to October 1938, published as 

"at Juncal Reservoir, near Montecito."

Sage. Water-stage recorder on 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 bench mark), or 2,000 ft above arbitrary datum (called sea level) generally used 

for works in this vicinity.

Average discharge. 28 years (1931-59), 5.95 cfs (4,310 acre-ft per year); median of 

yearly mean discharges, 2.2 cfs (1,600 acre-ft per year).

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

precipitation on lake. Net runoff computed on basis of records of storage, diversion 

(draft) to the city of Montecito, spill and release to river, and evaporation. Records 

of net runoff exclude precipitation on lake surface. Monthly evaporation from lake 

surface computed on basis of evaporation from Class A pan using coefficient of 0.80. 

Capacity and area ratings for this lake are based on surveys made in 1948. Lake 

capacity at spillway level (gage height, 223.82 ft), 6,590 acre-ft. Dead storage, 

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

There is no regulation or diversion above Jameson Lake. A very small amount of flow 

from Alder Creek (a tributary to Santa Ynez River 2 miles downstreair, from Juncal Dam) 

is diverted at elevation 2,250 ft through a tunnel to Jameson Lake and is included in 

these records.

Cooperation. Reservoir-operation records and related data furnished by Montecito County 

"Water District.

Drainage area. 2)90 sq mi*

Records available.-rOctober 1943 to September 1959. December 1929 to September 1933 at 

site 0.2 mile downstream; low-flow records not equivalent owing to diversion immediately upstream.

Gage.--Water-stage recorder. Datum of gage is 624.30 ft above mean sea level, datum of 

1929 (Corps of Engineers bench mark). Prior to Aug. 24, 1951, at site 0.2 mile downstream at datum 3.70 ft lower; during this period a supplementary gage at site 200 ft 

downstream from present site at different datums was generally used for periods of low 

flow.

Average discharge. 16 years (1943-59), 30.0 cfs (21,720 acre-ft per year); median of 

yearly mean discharges, 15 cfs (10,900 acre-ft per year).

Extremes.--Maximum discharge during year, 1,530 cfs Feb. 16 (gage height, 5.70 ft); minimum daily, 0.7 cfs Sept. 26, 27.

1930-33, 1943-59: Maximum discharge, 7,640 cfs Apr. 3, 1958 (gage height, 10.62 ft), 

from rating curve extended above 1,400 cfs on basis of slope-area measurement at gage 

height 10.08 ft; minimum daily since 1943, 0.4 cfs Sept. 14, 19, 21, 1947, Oct. 5-9, 

20-22, Nov. 18, 1951, and Nov. 2-11, 1957.

Maximum discharge known, 11,000 cfs Mar. 2, 1938 (gage height, 8.1 ft, from highwater mark in gage well at site in use 1929-33), from rating curve extended above 

2,800 cfs by logarithmic plotting.

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

periods of indefinite stage-discharge relation, which are poor. Discharge measurement? 

generally made twice a month.

1910. Kern River below Isabella Dam, Calif.

Location. Lat 35°38'30", long 118°28'55", in S|NW£ sec.30, T.26 S., R.33 E., on right 

bank 200 ft downstream from highway bridge, 0.6 mile downstream from Isabella Dam, and 

1.6 miles southwest of Isabella.

Drainage area. 2,094 sq mi.

Records available.--April 1945 to September 1959. Prior to October 1952, published as 

"below Isabella dam site."

Gage.--Water-stage recorder. Datum of gage is 2,435.07 ft above mean sea level (levels 

by Corps of Engineers). Prior to Mar. 12, 1952, water-stage recorder at site 0.6 mile 

upstream at different datum. Mar. 12, 1952, to July 26, 1953, staff gage at present 

site and datum.

Average discharge. 14 years, 797 cfs (577,000 acre-ft per year), adjusted for diversion 

since 1945 and for storage and evaporation since 1954.

Extremes. Maximum discharge during year, 1,420 cfs June 24 (gage height, 8.48 ft); minimum daily, 0.3 cfs Nov. 16-21.

1945-53 (prior to regulation by Isabella Reservoir): Maximum discharge, 39,000 cfs 

Nov. 19, 1950 (gage height, 28.6 ft, from floodmark, present site and datum), from 

rating curve extended above 1,100 cfs on basis of slope-area measurement of peak flow; 

minimum, 2.1 cfs (regulated) Nov. 27, 1951.

1954-59: Maximum discharge, 4,260 cfs June 28, 1958 (gage height, 15.14 ft); no 

flow Oct. 29, 1954.

Remarks. Records excellent except those below 20 cfs, which are good. Flow regulated by 

Isabella Reservoir beginning Apr. 15, 1954 (see preceding page). Borel Canal (see 

p. 295 ) diverts above the station. Diversions for irrigation of about 3,500 acres 

between head of Isabella Reservoir and upstream stations. An additional 6,500 acres 

in reservoir bottom can be irrigated when reservoir stage is low. Records of chemical 

analyses for the water year 1959 are given in WSP 1644.

Records available. September 1912 to September 1915, March 1922 to September 1959.

Gage. Water-stage recorder. Altitude of gage is 2,400 ft, revised (from topographic map). 

Prior to 1922, at site 2.2 miles downstream at different datum.

Average discharge. 34 years (1925-59, period since diversion began through Ward tunnel), 

1,330 cfs (962,900 acre-ft per year).

Extremes.--Maximum discharge during year, 5,920 cfs Feb. 16 (gage height, 13.51 ft); minimum daily, 95 cfs Sept. 1, 5, 11.

1912-15, 1922-59: Maximum discharge, 63,000 cfs Dec. 23, 1955 (gage height, 24.75 

ft), from rating curve extended above 14,000 cfs on basis of computation of peak flow 

over dam; minimum daily, 52 cfs Sept. 24, 1931.

Remarks. Records good. Flow partly regulated by Florence Lake (see p. 341) and diversions through Ward tunnel (see p. 349) beginning in 1925 and Lake Thomas A. Edison 

beginning in 1954 (see p. 344).

380 SAN JOAQUIN RIVER BASIN

2615. San Joaquin River at Premont Ford Bridge, Calif.

Location.--Lat 37 0 18'35", long 120°55'45", in Orestimba Grant, on left bank 150 ft downstream from Fremont Ford Bridge, Merced County, 2.1 miles downstream from Salt Slough, 

4.5 miles west of Stevinson, and 6.7 miles upstream from Merced River.

Drainage area. 8.090 sq mi, approximately.

Records available. March 1937 to September 1959 in reports of Geological Survey. February 1937 to September 1959 in reports of California Department of Water Resources. 

Monthly discharge only for some periods, published in WSP 1315-A.

Gage.--Water-stage recorder. Datum of gage is 3.77 ft below (corrected) mean sea level. 

Prior to Dec. 8, 1949, on downstream side of Fremont Ford Bridge near left bank at 

same datum.

Average discharge. 22 years, 928 cfs (671,800 acre-ft per year).

Extremes. Maximum discharge during year, 760 cfs Apr. 28 (gage height, 62.28 ft); minimum, 26 cfs Nov. 27.

1944-59: Maximum discharge, 5,910 cfs Apr. 6, 1958 (gage height, 71.14 ft); minimum, 18 cfs Oct. 18, 1949.

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

-Natural flow of stream affected by storage reservoirs, ground-water withdrawals, 

diversions for irrigation, and imported water from Delta-Mendota Canal (see p. 444). 

During periods of high flow, some water bypasses this station through Mud Slough; 

low flows consist mainly of return water from irrigated areas. See Remarks for 

stations upstream. Records of chemical analyses for the water year 1959 are given 

in WSP 1644.

basin for power, irrigation, and domestic supply in the vicinity of Sonora upstream 

from station. Some of the diverted water, up to 2 cfs, returns to Stanislaus River 

basin, and up to 4 cfs enters Tuolumne River basin upstream from Woods Creek.

1957-59: Maximum discharge, 12,200 cfs Apr. 4, 1958 (gage height, 17.25 ft), from 

rating curve extended above 6,OOC cfs by logarithmic plotting; minimum daily, 0.4 cfs 

Oct. 1-12, 1957.

Flood of Dec. 23, 1955, reached a peak discharge of 62,900 cfs (gage height, 

unknown), by computation of flow over Goodwin Dam.

Remarks. Records good. Flow regulated by reservoirs and powerplants at Donnells, Lake 

Hartley, Melones, Tullock, and several smaller reservoirs above station. South San 

Joaquin Canal (see p. 427) and Oakdale Canal (see p. 428 ) divert at Goodwin Dam 

1.0 mile upstream. Records of chemical analyses for the water year 1959 are given in 

WSP 1644.

SACRAMENTO RIVER BASIN 527

3995. North Fork Feather River near Prattville, Calif.

Location. Lat 40°10' , long 121°06', in SW^ sec.28, T.27N., 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.

Records available. June 1905 to September 1959 (daily discharges for July 1921 to September 1936 include water diverted through Almanor-Butt Creek tunnel). Records for water

v year 1911 incomplete, yearly estimate published In WSP 1315-A. Published as "below 

Prattville" prior to 1911. Supplemental records for Almanor-Butt Creek tunnel diversion computed November 1934 to Dec. 30, 1958, as difference of flow between Butt Creek 

above Almanor-Butt Creek tunnel, see following page (unpublished prior to 1936), and 

Butt Creek below Almanor-Butt Creek tunnel, see page 538 (unpublished prior to 1938). 

Prior to November 1924, method of determining diversion not known.

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

~^,380 ft (from topographic map). Prior to Oct. 1, 193G, staff gages or water-stage 

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

Average discharge.--54 years, 912 cfs {660,300 acre-ft per year), including diversion 

through Almanor-Butt Creek tunnel.

Extremes.--Maximum discharge during year, 807 cfs Nov. 20 (gage height, 4.35 ft); minimum 

daily, 9.5 cfs Apr. 17-30. Extremes do not include diversions through Almanor-Butt 

Creek tunnel.

1905-59: Maximum discharge, 10,000 cfs 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 January to April 1919, Apr. 21, 1923.

Remarks. Records excellent. Flow regulated by Lake Almanor beginning In 1913 (see preceding page). Water diverted for power from Lake Almanor through old Almanor-Butt Creek 

tunnel to Butt Creek until Dec. 30. Diversion through new tunnel and Butt Valley powerhouse began Dec. 31, 1958. Figures of daily discharge show flow of river only; monthly 

figures show combined flow of river and tunnel.

Cooperation. Water-stage-recorder graph, 10 discharge measurements, and diversion through 

Butt Valley powerhouse furnished by Pacific Gas & Electric Co. in connection with a 

Federal Power Commission project.

Revisions (water years)--WSP 1245: 1951 (yearly summaries). WSP 1285: 1952 (yearly

summaries).

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 1929 (low-water periods only), October 1929 

to September 1959.

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, at datum of Corps of Engineers. Prior to Oct. 1, 1944, auxiliary water-stage 

recorder at site 19.2 miles downstream at datum 0.12 ft above mean sea level (datum 

of 1929).

Average discharge.--30 years (1929-59), 17,980 cfs (13,020,000 acre-ft per year).

Extremes. Maximum discharge during year, 62,900 cfs Feb. 19 (gage height, 35.26 ft); 

minimum,5,470 cfs June 26.

1926-59: 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.

1934-59: Maximum combined discharge of Sacramento River at Verona and Fremont 

weir, about 315,000 cfs Mar. 1, 1940.

Remarks. Records excellent. Discharge measurements generally made twice a month. Flow 

regulated by Shasta Lake beginning Dec. 30, 1943, several other reservoirs and 

powerplants above station, and by bypassing for flood control. Many diversions above 

station for irrigation. When discharge exceeds about 55,000 cfs, flow begins over 

Fremont weir (just upstream) into Yolo bypass (see p. 612). Elevation of crest of 

Fremont weir is 33.5 ft (datum of Corps of Engineers).

Cooperation. Twelve discharge measurements furnished by California Department of Water 

Resources.

SACRAMENTO RIVER BASIN 575

4270. North Fork American River at North Fork Dam, Calif.

Location. Lat 38=56'15", long 121°01'25", in SW£NW£ sec.31, T.13 N. , R.9 E., on left 

bank 50 ft upstream from spillway of North Fork Dam, 2 miles upstream from Middle 

Fork, and 4 miles northeast of Auburn.

Drainage area.--343 sq mi.

Records available.--October 1941 to September 1959.

Gage. Water-stage recorder, 

jorps of Engineers).

Datum of gage is 715.0 ft above mean sea level (levels by

Average discharge.--18 years, 837 cfs (606,000 acre-ft per year).

Extremes.--Maximum discharge during year, 7,870 cfs Feb. 16 (gage height, 4.47 ft); minimum, 22 cfs Sept. 13.

1941-59: Maximum discharge, 49,100 cfs Dec. 23, 1955 (gage height, 10.22 ft), from 

rating curve extended above 22,000 cfs on basis of computed flow over spillway of dam; 

no flow Aug. 27-30, Sept. 2-11, 1944, caused by operation of valves in North Fork Dam.

Remarks. Records good. Flow regulated by Lake Clementine (capacity, 12,800 acre-ft) 

formed by North Fork Dam. Storage in Big Reservoir and Lake Valley Reservoir (combined capacity, 10,300 acre-ft) above station. Lake Valley Canal diverts from North 

Fork of North Fork American River into Bear River basin for power development in Alta 

powerhouse of Pacific Gas & Electric Co. Combined storage and diversion have small 

effect on natural flow.

Average discharge. 29 years 485 cfs (351,100 acre-ft per year); median of yearly mean

 discharges, 350 cfs (253,000 acre-ft per year). Adjusted for storage in and evaporation from Lake Berryessa.

Extremes. Maximum discharge during year, 906 cfs Feb. 16 (gage height, 8.44 ft); minimum, 5.4 cfs Dec. 10.

1930-59: Maximum discharge, 81,000 cfs Feb. 27, 1940 (gage height, 30.5 ft, present 

datum), from rating curve extended above 30,000 cfs by logarithmic plotting; no flow 

Sept. 6-15, 1950, July 26 to Sept. 1, Sept. 6-9, 1955.

Maximum stage known since at least 1905, that of Feb. 27, 1940, on basis of records 

for station at Winters.

Remarks. Records good. Low-water records are not equivalent to records at Winters or 

near Davis. Flow regulated by Lake Berryessa beginning Jan. 11, 1957 (see p. 614 ).

668 LOST RIVER BASIN

4860. Lost River diversion canal near Olene , Oreg.

Location. Lat 42°09' , long 131 "40 ' , in SW£ sec. 29, T.39 S., R.10 E. , on left bank at 

Lost River Dam, 4 miles southwest of Olene.

Records available , May 1912 to September 1959. Published as "near Klamath Palls" 

1916-18.

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

3aily. Altitude of gages is 4,080 ft (from topographic map). Mar. 29, 1916, to 

Apr. 22, 1918, and at times May 4, 1923, to Sept. 30, 1933, water-stage recorders at 

sites within 1 mile downstream at different datums.

Average discharge .--43 years (1912-15, 1919-59), 160 cfs (115,800 acre-ft per year). 

Extremes .--1912-59: Maximum daily discharge, 2,860 cfs Jan. 16, 1956; 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 

from right bank of Lost River in SW£ sec. 29, T.39 S., R.10 E., and discharges into 

Klamath River in NW£ sec. 17, T.39 S., R.9 E., for reclamation of land in the vicinity 

of Tule Lake. Discharge includes water occasionally wasted from "C" Canal (diversion 

from Link River), but none during 1959 water year. Beginning in July 1951, records 

include water later removed from the canal by Miller Hill pumping plant which operates 

at times; during period May through August 1959, pumpage (from Lost River source) 

amounted to 5,940 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, p. 679).

Cooperation. Records furnished by Bureau of Reclamation; reviewed by Geological Survey.

Discharge, in cubic feet per second, water year October 1958 to September 1959

678 KLAMATH RIVER BASIN

5075. Link River at Klamath Falls, Oreg.

Location. Lat 42°13', long 121°48', in NW^ sec.32, T.38 S. , R.9 E., on left bank 600 ft 

upstream from outlet of Keno Canal and three-eighths of a mile upstream from Main 

Street Bridge at Klamath Falls.

Drainage area.--3,810 sq mi, approximately (includes 27 sq mi in closed basin of Crater 

Lake).

Records available. May 1904 to September 1959.

Gage.--Water-stage recorder. Datum of gage is 4,083.71 ft above mean sea level, datum 

of 1929, or 4,085.50 ft above mean sea level, datum of Bureau of Reclamation. Prior 

to Sept. 14, 1912, water-stage recorder, staff and chain gages at several sites within 

half a mile of present site at various datums. Sept. 14, 1912, to N v. 23, 1923, 

water-stage recorder at site 600 ft downstream at datum 5.42 ft lower.

Average discharge.--55 years, 1,623 cfs (1,175,000 acre-ft per year).

Extremes.--Maximum discharge during year, 3,320 cfs Jan. 5; minimum daily, 404 cfs Apr. 30.

1904-59: Maximum discharge, 9,400 cfs May 12, 1904 (gage height at Main Street 

Bridge, 7.30 ft, datum then in use, from floodmarks); minimum daily, 17 cfs Dec. 13, 

1937.

Remarks.--Records good. Flow regulated since April 1919 by Upper Klamath Lake (see preceding page). Large diurnal fluctuation caused by powerplant above station. Water 

diverted above station by main or "A" Canal of Klamath project (see p. 676). Many 

other diversions above lake. All records presented herein include flow in Keno Canal 

which, since September 19u8, has diverted from Upper Klamath Lake at Link River Dam, 

4,800 ft above station, for power generation, and returns flow to Link River 600 ft 

below station.

Revisions (water years). WSP 1565: 1907.

KLAMATH RIVER BASIN 679

Location. --Lat 42°09', long 121°42' 

5 miles southwest of Olene .

in SWij- sec. 30, T.39 S., R.10 E., on right bank

Gage.--Staff gage read once daily. Altitude of gage is 4,080 ft (from topographic map).

Average discharge. 29 years, 32.7 cfs (23,670 acre-ft per year).

Extremes.--la31-59: Maximum daily discharge, 7ly 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 Tule Lake (see record for Lost River diversion canal near Olene, p. 668). 

Beginning in April 1931, water has been diverted at times from Klamath River and 

released into Lost River, from which it is rediverted for irrigation of lands near 

Tule Lake. Since 1949, records include water pamped from the diversion canal by 

Killer Hill pumping plant (capacity, 70 cfs); during April, June, and July 1959, pumpage amounted to 4,680 acre-ft.

minimum, 26 cfs Sept. 23, 1956; minimum daily, 60 cfs May 19, 1934.

Maximum stage known, 15.3 ft, from floodmark (original datum), about May 10, 1904 

(discharge, 9,250 cfs).

Remarks.--Records good. Plow regulated by Upper Klamath Lake since 1919 (see p. 677). 

Diurnal fluctuation caused by powerplants above station. Diversions for irrigation 

above station. Lost River diversion canal enters or diverts from Klamath River above 

station (see records for Lost River diversion canal near Olene, p. 668, and Diversion 

from Klamath River to Lost River near Olene, preceding page). Diversions through Midland Canal (since 1947) to Klamath Drainage District and through Klamath Strait into 

Lower Klamath Lake were computed by Bureau of Reclamation from gate openings at Midland 

and Ady. Pumpage into Klamath River at Ady was computed by Bureau of Reclamation from 

hours of pump operation.

DISCHARGE AT PARTIAL-RECORD STATIONS AND MISCELLANEOUS SITES '"

As the number of streams on which streamflow information is likely to be desired far 

exceeds the number of stream-gaging stations feasible to operate at one time, the Geological Survey collects limited streamflow data at sites other than stream-gaging stations. 

When limited streamflow data are collected on a systematic basis over a period of years 

for use in hydrologic analyses, the site at which the data are collected is called a 

partial-record station. Data collected at these partial-record stations are usable in 

low-flow or flood-flow analyses, depending on the type of data collected. In addition, 

discharge measurements are made at other sites not included in the partial-record program. 

These measurements are generally made in times of drought or flood to give better areal 

coverage to those events. Those measurements and others collected for some special reason 

are called measurements at miscellaneous sites.

Records collected at partial-record stations are presented in two tables. The first is 

a table of discharge measurements at low-flow partial-record stations, and the second is 

a table of annual maximum stage and discharge at crest-stage stations. Discharge measurements made at miscellaneous sites for both low flow and high flow are given in B third 

table.

Low-flow partial-record stations

Measurements of streamflow in the area covered by this report made at low-flow, partialrecord stations are given in the following table. Most of these measurements were made 

during periods of base flow when streamflow is primarily from ground-water storage. These 

measurements, when correlated with the simultaneous discharge of a nearby stream where 

continuous records are available, will give a picture of the low-flow potentiality of 

stream. The column headed "Period of record" shows the water years in which measurements 

were made at the same, or practically the same, site.

726 DISCHARGE AT PARTIAL-RECORD STATIONS AND MISCELLANEOUS SITES

Crest-stage partial-record stations

The following table contains annual maximum discharges for crest-stage stations. A 

crest-stage gage is a device which will register the peak stage occurring between inspections of the gage. A stage-discharge relation for each gage is developed from discharge 

measurements made by indirect measurements of peak flow or by current meter. The date ol 

the maximum discharge is not always certain but is usually determined by comparison with 

nearby continuous-record stations, weather records, or local inquiry. Only the maximum 

discharge for each water year is given. Information on some lower floods may have been 

obtained but is not published herein. The years given in the period of record represent 

water years for which the annual maximum has been determined.
