SURFACE WATER SUPPLY OF PACIFIC SLOPE BASINS IN CALIFORNIA, 1960

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 1960 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 

15,500 gaging stations in the 50 States. On September 30, 1960, the Geological Survey 

and cooperating organizations were maintaining 7,300 gaging stations. Partial-record 

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 

1960 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; Calaveras County 

Water District; Contra Costa County Flood Control and Water Conservation District; Marin 

Municipal Water District; Montecito County Water District; North Marin County Water District; Santa Clara County Flood Control and Water Conservation District; Orange County 

Flood Control 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; Santa 

Maria Valley Water Conservation District; Ventura River Municipal Water District; 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 62 gaging stations, 

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

States Department of the Interior, for 50 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,

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.................... 1002 N.E. Holladay Street.

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. All 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 selected number of consecutive days in 

each year; and (3) the highest mean discharge for selected number of consecutive days in 

each year. Provisional records of discharge, information on the availability of elec-- 

tronic 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:

Gating 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.

WSF 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 arid 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, 1960, PART 11

daily flow. The recorda of stage are obtained either from direct readinga on a nonrecording gage or from a water-atage recorder that givea a continuoua record of fluctuationa. 

Meaaurements of diacharge are made with a current meter by the general methods adopted by 

the Geological Survey on the baaia of experience in stream gaging aince 1888. Theae 

methoda are deacribed in Water-Supply Paper 888 and are alao outlined in standard textbooks on the measurement of atream diacharge.

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

relation curvea defined by discharge meaaurementa. If extensions to the rating curvea 

are neceaaary to define the extremea 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 1960 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 and 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. The references to 

"datum of 1929" and adjustments of other years are to the datum and adjustments of the 

U. S. Coast and Geodetic Survey. 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 gage, 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.
6 SURFACE WATER SUPPLY, I960, PART 11

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. 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.
ACCURACY OP FIELD DATA AND COMPUTED RESULTS 7

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.

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

making chemical analyses, computing dissolved solids, 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-water 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
8 SURFACE WATER SUPPLY, 1960, PART 11

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

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.

beginning of records through June 30, 1912. They supersede records published In the 10th to 22d 

Annual Reports, Bulletins 131 and 140, and earlier water-supply papers.

Compilation of records for the area covered by this report through September 1950 have 

been published in two volumes; WSP 1311-A, Pacific slope basins in California, Central 

Valley, and WSP 1311-B, Pacific slope basins in California except Central Valley. These 

reports contain a summary of monthly and annual discharges for all previously published 

records as well as some records not contained in the annual series of water-supply papers. 

All records were reexamined and revised where warranted. Estimates of discharge were 

made to fill short gaps whenever practical.

HYDROLOGIC CONDITIONS

Streamflow was well below median over the entire area. Runoff in the north coastal 

region was about 85 percent of median and in the Central Valley region about 65 percent 

of median. Runoff from both the central coastal and south coastal regions was only about 

25 percent of median. The seriously deficient Streamflow of the fall and early winter 

was climaxed in the northern half of the area by heavy rains in early February, and fairly 

serious flooding resulted. The remainder of the year was relatively dry and drought conditions continued unabated in the southern half of the area.

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 1960 water year with 

the median discharge for the period 1931-60.

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

Location. Lat 32°40'45", long 116 0 40'20", in NW£ sec.22, T.17 S., R.3 E., on Barrett Dam 

outlet tower, 17 miles northeast of Dulzura.

Drainage area. 250 sq mi.

Records available. January 1906 to December 1915, October 1945 to September 1960. Published as "near Jamul" prior to October 1912 and as "near Dulzura" October 1912 to 

December 1915. October 1936 to September 1945, published as "near Dulzura"; records 

not equivalent, as they were computed to represent runoff from Cottonwood Creek basin 

below Morena Dam (drainage area, 130 sq mi).

;e. 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 58.88 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 reservoir was small and other quantities were large, 

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

Inflow 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.
28 SAN DIEGO RIVER BASIN

220. San Vlcente Creek at San Vicente Dam, at Foster, Calif.

Location (revised) . Lat 32°54'45", long 116"55'25", in SE£sw£NW£ sec.31, T.14 S., R.I E.,

 near center 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 1941, October 1942 to

 September I960. Published as "at Foster" prior to October 1942.

Gage. Staff gage read once dally. Water-stage recorder on spillway. Hygro-Thermograph 

and anemometer. 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. Since Sept. 23, 1957, auxiliary hydrological instruments on reservoir.

Remarks. Records of total Inflow represent all water reaching San Vicente Reservoir from

 basin of San Vicente Creek, precipitation on reservoir, supplemental Colorado River 

water, Santa Ysabel Creek, and San Diego River water. Total inflow is computed on 

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

of net inflow exclude supplemental Colorado River water and Santa Ysabel Creek water 

delivered to this reservoir from Sutherland Reservoir by city of San Diego Water Department Prior to October 1957, monthly evaporation from reservoir surface computed on 

basis of Colorado pan using coefficient of 0.80. Since October 1957, evaporation computed by mass-transfer method. Capacity and area ratings for reservoir are dated 

2-18-44. 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, 

Included in these records. No 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 net Inflow may appear. This arises primarily from the difficulty of computing net 

Inflow 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. Since January 

1957 water was released from Sutherland Reservoir periodically.
SAN DIEGO RIVER BASIN

30 225. San Diego River near Santee, Calif.

Location.--Lat 32°49'27", long 117°03'17", in Ex Mission San Diego Grant, on right bank 

in Mission Gorge, 0.2 mile upstream from left tributary and 6 miles west of Santee, 

San Diego County.

Drainage area.--380 sq mi.

Records available.--May 1912 to December 1915, March 1916 to September 1960. Monthly discharge only for some periods and yearly estimates only for 1924-25, published in 

WSP 1315-B.

Gage. Water-stage recorder and unfinished rubble dam control. Altitude of gage is 180 ft 

Cfrom topographic map). Prior to Nov. 10, 1920, staff gage at site ! § miles upstream 

at different datum. Nov. 10, 1920, to Dec. 1, 1954, water-stage recorder at present 

site at datum 1.0 ft higher.

Average discharge.--47 years, 26.5 cfs (19,190 acre-ft per year); median of yearly mean 

discharges, 4.8 cfs (3,500 acre-ft per year).

Extremes. Maximum discharge during year, 196 cfs Jan. 12 (gage height, 2.74 ft); minimum daily, 0.3 cfs Oct. 21.

1912-60: Maximum discharge, 70,200 cfs Jan. 27, 1916 (gage height, 25.1 ft, site 

and datum then in use), on basis of velocity-area study; no flow at times in most 

years.

Remarks. Records fair. Discharge measurements generally made twice a month. Plow regulated by Cuyamaca, El Capitan (see p. 26, 27), and San Vicente Reservoirs. Diversions 

above station by city of San Diego for municipal supply and by Helix Irrigation District. Average discharge represents flow to ocean during period of record, regardless 

of upstream development.

Revisions (water years).--WSP 1565: 1955-56. WSP 1635: 1922, 1926(M), 1927.

of Raiaona.

Drainage area. 54.0 sq mi (revised).

Records available. December 1912 to September 1928, October 1936 to September 1960. 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 daturas. 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

median of yearly mean discharges, 11 cfs (8,000 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.

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 

by mass-transfer method. 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. 31).

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, discordant 

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

Inflow 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.

38 SAN LUIS KEY RIVER BASIN

350. San Luis Key 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. 206 sq mi (revised).

Records available. October 1922 to September 1960. October 1911 to September 1922 at 

site 1 mile downstream published as "near Mesa Grande"; records not equivalent owing to 

change in natural water losses resulting from creation of Lake Henshaw. Monthly net 

runoff only October to December 1922, published in WSP 1315-B.

Gage. Staff gage read once daily.

Fo June 14, 1912, staff gage at same site at different datum.

Datum of gage is 2,620 ft above mean sea level. Prior 

ame site at different datum. June 14, 1912, to Oct. 7, 

1922, 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; 

38 years (1922-60) , 28.3 cfs (20,460 acre-ft per year), discharge at Lake Henshaw, 

exclusive of 90 percent of precipitation on lake surface; median of yearly mean discharges, 17 cfs (12,000 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 began, runoff as computed has been 

exclusive of 90 percent of rainfall on water surface of lake. During year the amount 

of precipitation excluded was 938 acre-ft. 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. No diversion above Lake Henshaw.

Cooperation. Records furnished by Vista Irrigation District.

Location. Lat 33°29'44", long 116 0 58'33", in Pauba Grant, at Vail Dam 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 1960. October 1948 to September 1951, published as "at Nigger Canyon, near Temecula"; records are for draft and spill only from 

Vail Lake. October 1951 to September 1955 published as "at Vail Dam, near Temecula."

Gage. Water-stage recorder and wire-weight gage. Datum of gage is 1,350.0 ft above mean 

sea level (levels by Bureau of Reclamation). Water-stage recorder at site 500 ft downstream measures release and spill.

Average discharge. 12 years, 5.13 cfs (3,710 acre-ft per year); median of yearly mean discharges, 2.6 cfs (1,900 acre-ft per year).

Remarks. Records of runoff represent all water reaching Vail Lake, including precipitatlon on take surface. Runoff computed on basis of records of storage, release (draft), 

spill, and evaporation. Monthly evaporation from lake surface, computed on basis of 

evaporation from Class A pan using coefficient of 0.77. Capacity and area ratings for 

lake are based on a survey made in 1947. Capacity of lake at spillway level (gage 

height, 120.00 ft), 49,370 acre-ft. Dead storage, 2.4 acre-ft below lowest outlet at 

gage height 2.5 ft, included in these records. Water is released down Temecula Creek 

for diversion about 1 mile below dam as required.

Cooperation. Records of lake water-surface elevations furnished by Santa Margarita Ranch 

(U. S. Navy) and Pauba Ranch.

published in WSP 1315-B.

Monthly discharge only for some periods,

Gage.--Water-stage recorder. Datura of gage is 1,984.28 ft above mean sea level, datum of 

T929. Prior to Oct. 1, 1914, staff gages at various sites within 1,000 ft of point 

lj miles upstream at various datums (records for this period not equivalent to subsequent records because of Greenspot pipeline diversion between sites). Oct. 1, 1914, 

to Jan. 17, 1916, staff gage at site 10 ft upstream at different datum. Jan. 18, 1916, 

to Sept. 2, 1917, staff gage at same site and datura.

Average discharge. 46 years (1914-60), 30.6 cfs (22,150 acre-ft per year); median of 

yearly mean discharges, 9.2 cfs (6,700 acre-ft per year). Average combined discharge 

of Santa Ana River and canal, 64 years (1896-1960) 84.0 cfs (60,810 acre-ft per year); 

median of yearly combined mean discharges, 70 cfs (50,700 acre-ft per year).

Extremes. Maximum discharge during year, 82 cfs Apr. 27 (gage height, 6.36 ft); no flow 

for much of year.

1896-1960: Maximum discharge, 52,300 cfs Mar. 2, 1938 (gage height, 14.3 ft), on 

basis of slope-area measurement of peak flow; no flow at times in some years.

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

two or more times a month. Plow partly regulated by Big Bear Lake (see preceding page). 

For records of combined discharge of Santa Ana River and Southern California Edison 

Co.'s canal below powerplant No. 2, which diverts above station, see following page. 

Bear Valley Mutual Water Co. pumped 556 acre-ft into canal below canal gage. Prior to 

Oct. 1, 1952, pumped water entered canal above gage.

Cooperation. Eleven discharge measurements on Southern California Edison Co.'s canal

below powerplant No. 2 furnished by that agency in connection with a Federal Power Commission project.

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

water pumped from the ground-water basin near Meeks and Daley Canal gage. In seasons 

of high-water 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).

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

Location. Lat 33°47'10", long 117°43'33", near west corner of lot 70 of Lomas de Santiago Grant, on upstream face near left end of Santiago Dam, 0.3 mile upstream from 

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

Drainage area. 63.2 sq mi.

Records available.--October 1931 to September 1960.

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

Average discharge. 29 years, 17.0 cfs (12,310 acre-ft per year); median of yearly mean 

discharges, 9.9 cfs (7,200 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 Metropolitan 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.

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

Inflow 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 GABRIEL RIVER BASIN 101

835. San Gabriel River near Azusa, Calif.

Location. Lat 34°10'H", long 117°53'16", in SW£NW&SW£ sec.13, T.I N., R.10 W., on right 

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

Drainage area. 211 sq mi.

Records available. Hay to November 1894, September 1895 to September 1960.

Gage. Water-stage recorder. Datum of gage is 867.59 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 I-g to 

2 miles downstream at different datums. 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. 65 years (1895-1960), 150 cfs (108,600 acre-ft per year), adjusted 

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

and Morris Reservoirs; median of yearly mean adjusted discharges, 110 cfs (79,600 

acre-ft per year).

Extremes. No flow during year.

TF94-1960: 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. No flow since Sept. 18, 1959. Observations of no flow made once or twice a 

month. Flow 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 748 acre-ft of Colorado River water into San Gabriel River below 

Morris Dam and above station during the 1960 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. Figures of discharge for the calendar year 

n SLare as follows : maximum daily, 348 cfs; minimum, zero; mean, 11.3 cfs: runoff 

8,200 acre-ft.

been found to be unreliable and should not be used. Equivalent daily discharge, published as "below Sepulveda Dam" 1943-45, and as "below Sepulveda Boulevard" (in 

reports of Los Angeles County Flood Control District) 1946-50, supersede the discredited records.

Gage (revised).--Water-stage recorder. Altitude of gage is 670 ft (from topographic map). 

Prior to Aug. 23, 1941, at site 1 mile downstream at different datum; Aug. 23, 1941, 

to Sept. 30, 1950, at site 900 ft downstream at different datum; Oct. 1, 1950, to 

Aug. 29, 1953, at site 800 ft upstream at datum 5.99 ft higher.

Average discharge.--30 years (1929-37, 1938-60), 20.4 cfs (14,770 acre-ft per year); 

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

Extremes. Maximum discharge during year, 5,320 cfs Jan. 11 (gage height, 5.58 ft); miniiunTcTaily, 2.4 cfs Oct. 12, 13.

1929-37, 1938-60: Maximum discharge, 10,300 cfs Dec. 15, 1957 (gage height, a45 ft); 

no flow Sept. 19, 20, 1930.

Flood of Mar. 2. 1938, 12,000 cfs (estimated).

Remarks. Records good. Discharge measurements generally made once a week. Flow regulated by Sepulveda flood-control reservoir (capacity, 17,400 acre-ft). Some diversion 

above station. City of Los Angeles stores Imported Owens River water in San Fernando, 

Chatsworth, and Encino Reservoirs and at times discharges imported water into Los 

Angeles River above station from Chatsworth and Encino Reservoirs. This inflow 

amounted to 3,580 acre-ft during current year.

Cooperation. Thirty-three discharge measurements furnished by Los Angeles County Flood 

Control District. Records of released water from Chatsworth and Encino Reservoirs furnished by city of Los Angeles.

Revisions. See Records Available.

Records available.--January 1941 to September 1960.

Gage. Water-stage recorder. Altitude of gage is 130 ft (from topographic map). Prior 

to July 1, 1958, at datum 2.00 ft higher.

Average discharge. 19 years, 1.71 cfs (1,240 acre-ft per year); median of yearly mean 

discharges, 0.3 cfs (220 acre-ft per year).

Extremes.--Maximum discharge during year, 44 cfs Feb. 1 (gage height, 3.25 ft); no flow 

for most of year.

1941-60: Maximum discharge, 2,440 cfs Jan. 15, 1952 (gage height, 9.75 ft, present datum), from rating curve extended above 500 cfs on basis of slope-area measurement of peak flow; no flow at times in each year.

Remarks.--Records good. Discharge measurements or observations of no flow made twice a 

month. Gobernador Land and Water Co. diverts from Gobernador Creek 1.8 miles above 

station. Small lake three-quarters of a mile southeast of station and outside the 

drainage area stores storm runoff and surplus water diverted by Gobernador Land and 

Water Co. from Gobernador Creek. At times this lake is drained by pumping water into 

Gobernador Creek 1,000 ft above station. No pumping occurred this year.

164 SANTA YNEZ RIVER BASIN

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

Location.--Lat 34°29'32", long 119 0 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 1960. 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.--29 years (1931-60), 5.75 cfs (4,160 acre-ft per year); median of 

yearly 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 downstream 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.

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.
SANTA YNEZ RIVER BASIN 

1220. Santa Ynez River above Gibraltar Dam, near Santa Barbara, Calif.

165

Location. Lat 34°31'37", long 119°41'10", on upstream side of Gibraltar Dam, 7 miles 

north of Santa Barbara, Santa Barbara County.

Drainage area. 216 sq mi.

Records available. April 1920 to September 1960. November 1903 to November 1918 (fragmentary) at river station at damsite; records not equivalent, because records since 

April 1920 are based on operation of Gibraltar reservoir, and since December 1930, 

Jameson Lake. Prior to October 1943, published as "near Santa Barbara."

Gage. Water-stage recorder on reservoir and water-stage recorder and sharp-crested weir 

on diversion canal below dam. Spill and release measured at river gaging station below 

dam (see following page). Datum of reservoir gage is at mean sea level., datum of 1929. 

Prior to August 1916, staff gage 900 ft downstream at different datum. August 1916 to 

June 1918 water-stage recorder at Gibraltar damsite at different datum. June to November 1918 staff gage at several sites and datums near dam. Apr. 1, 1920, to Oct. 1, 

1955, at datum 21.82 ft higher.

Remarks.--Records of total inflow represent all water reaching Gibraltar Reservoir, including precipitation on reservoir. Total inflow computed on basis of records of storage, 

diversion (draft) to city of Santa Barbara, spill and release to river, and evaporation. 

Records of net inflow exclude precipitation on reservoir surface. Monthly evaporation 

from reservoir surface computed on basis of evaporation from Class A pan using coefficient 0.80. Reservoir capacity and area tables are based on surveys made on 1956. Reservoir capacity at spillway level (elevation, 1,399.82 ft), 14,777 acre-ft. Dead storage, 716 acre-ft, below lowest outlet at elevation 1,333.86 ft, included in these records. Plow regulated by Jameson Lake since December 1930 (see preceding page).

Cooperation. Reservoir-operation records and related data furnished by city of Santa 

Barbara.

80 ft downstream at same datum.

Average discharge. 31 years (1929-60), 442 cfs (320,000 acre-ft per year); median of 

yearly mean discharges, 200 cfs (145,000 acre-ft per year).

Extremes. Maximum discharge during year, 1,750 cfs Feb. 10 (gage height, 7.50 ft, from 

graph based on gage readings); minimum not determined.

1900-1901, 1929-60: Maximum discharge, 75,000 cfs Feb. 12, 1938 (gage height, 

25.0 ft), from rating curve extended above 26,000 cfs on basis of velocity-area studies; 

maximum gage height, 26.85 ft Jan. 16, 1952, from floodmarks; no flow at times in 

1929-40.

Revisions. The figure of maximum discharge for the water year 1959 has been revised 

to 4,790 cfs Feb. 17, 1959 (gage height, 9.96 ft), superseding that published In 

WSP 1635.

Remarks. Records poor. Large withdrawals from ground water and small surface-water diversions for municipal use and irrigation of about 95,000 acres above station. Low flow 

represents waste water from Spreckels sugar refinery. Flow partly regulated by Nacimiento Reservoir beginning in November 1956 (usable capacity, 340,000 acre-ft). Records of chemical analyses for the water year 1960 are given In WSP 1744.

Revisions (water years). WSP 1565; 1930, 1935, 1945, Revised figures of discharge, In 

cubic feet per second, for the water year 1959, superseding those published in 

WSP 1635, are given herewith:

1875. Borel Canal below Isabella Dam, Calif.

Location. Lat 35 0 38 ! 30", long 118°28'10", in NE£ sec.30, T.26 S., R.33 E., on right bank 

500 ft downstream from Isabella Dam and 3 miles upstream from point where canal crosses 

Erskine Creek.

Records available. January 1910 to September 1914, October 1925 to September 1960. 

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

River Power Co.'s Canal at or near Kernville 1910-14 and as "at Tillie Creek" 1925-51.

Gage. Water-stage recorder. Altitude of gage is 2,540 ft (from topographic map). Prior 

to Apr. 29, 1952, at site 4 miles upstream at different datum.

Average discharge. 39 years (1910-14, 1925-60), 362 cfs (262,100 acre-ft per year). 

Extremes. 1925-60: Maximum daily discharge, 634 cfs Mar. 13, 14, 1952; no flow at times.

Remarks. Records good. Canal diverts from right bank of Kern River, 5.5 miles upstream 

from Isabella Dam, and above South Pork. When capacity of Isabella Reservoir is above 

110,000 acre-ft, the diversion is at the dam. Canal is used to supply Borel powerplant at Southern California Edison Co., 6 miles downstream from station, at which 

point water is returned to Kern River. Records of chemical analyses and water temperatures for the water year 1960 are given in WSP 1744.

Cooperation. Water-stage-recorder graph and 20 discharge measurements furnished by 

Southern California Edison Co. in connection with a Federal Power Commission project.

282 KERN RIVER BASIN

1910. Kern River below Isabella Dam, Calif.

Location. Lat 35°38'30", long 118°28'55", in SiNW£ see.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 1960. 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. 15 years, 770 efs (557,500 acre-ft per year), adjusted for diversion 

since 1945 arid for storage and evaporation since 1954.

Extremes. Maximum discharge during year, 1,210 efs June 26 (gage height, 8.14 ft); no 

flow Mar. 22.

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

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

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

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

1954-60; Maximum discharge, 4,260 efs June 28, 1958 (gage height, 15.14 ft); no 

flow Oct. 29, 1954, Mar. 22, 1960.

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

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

p. 277) diverts above 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 1960 are given in WSP 1744.

Revisions (water years). WSP 1345: Drainage area. WSP 1515; 1956.

Discharge, in cubic feet per second, water year October 1959 to September 1960

15.20 ft): minimum, 3.9 cfs Sept. 24-27.

1959-60: Maximum discharge during year, 116 cfs Feb. 8 (gage height, 3.95 ft); minimum daily, 5.6 cfs Sept. 13.

1921-57 (prior to regulation by Wishon Reservoir): Maximum discharge, 14,000 cfs 

Dec. 11, 1937 (gage height, 18.0 ft, from floodmarks), from rating curve extended 

above 4,200 cfs on basis of velocity-area studies and by logarithmic plotting; minimum, 0.6 cfs Dec. 30, 1930.

1957-60: Maximum discharge, 4,880 cfs May 28, 1958 (gage height, 11.75 ft); minimum daily, 0.8 cfs Dec. 14, 1957.

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

which are fair. Flow regulated by Wishon Reservoir since Dec. 5, 1957 (capacity, 

129,000 acre-ft), and Courtright Reservoir since Oct. 17, 1958 (capacity, 130,000 

acre-ft). Water diverted for power from Wishon Reservoir by tunnel to Haas powerhouse 

since Dec. 10, 1958.

Just downstream from spillway of Florence Lake Dam, 6 miles upstream from Bear Creek.

Drainage area. 171 sq mi.

Records available. October 1921 to September 1960. Monthly discharge only for some 

periods, published in WSP 1315-A. Prior to October 1925, published as ^'near Lake 

Florence."

Gage. Water-stage recorder, Parshall flume, and concrete control. Altitude of gage is 

7,200 ft (from topographic map).

Average discharge. 39 years, 306 efs (221,500 aere-ft per year), combined flow of South 

Fork San Joaquin River and Ward tunnel at intake.

Extremes. Maximum discharge during year, 7.7 efs July 4 (gage height, 8.87 ft); minimum daily, 3.1 efs for many days.

1921-60: Maximum discharge, 4,320 efs June 6, 1940 (gage height, 15.38 ft); no 

flow at times.

Remarks. Records excellent. Flow regulated by Florence Lake beginning in 1925 (see 

p. 324) and by diversion into Ward tunnel (see preceding page). Records of water 

temperatures for the water year 1960 are given in WSP 1744.

Cooperation.--Water-stage-recorder graph furnished by Southern California Edison Co. in 

connection with a Federal Power Commission project.

0.8 mile upstream from Ross Creek and 2.3 miles upstream from Big Creek.

Drainage area. 1,050 sq mi.

Records available. September 1912 to September 1915, March 1922 to September 1960. 

Published as "near Shaver" 1912-15.

Gage. Water-stage recorder. Altitude of gage is 2,400 ft (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 

and prior to regulation by Mammoth Pool Reservoir), 1,330 cfs (962,900 acre-ft per year).

Extremes. Maximum discharge during year, 962 cfs Feb. 8 (gage height, 8.66 ft); minimum 

daily, 3.9 cfs Nov. 28-30.

1912-15, 1922-60: 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, that of Nov. 28-30, 1959.

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

Flow partly regulated by Florence Lake (see p. 324) and diversions through Ward tunnel 

(see p. 323) beginning in 1925, Lake Thomas A. Edison beginning in 1954 (see p. 327), 

and Mammoth Pool Reservoir beginning in 1960 (see p. 331). Records of water temperatures for the water year 1960 are given in WSP 1744.

Cooperation.--Water-stage-recorder graph and 25 discharge measurements furnished by

Southern California Edison Co. in connection with a Federal Power Commission project.

Revisions.--WSP 1635: Drainage area (at present and former sites).

Records available. June 1925 to September 1960 (records prior to 1929 including both 

spill and leakage from Huntington Lake, published in WSP 1635).

Gage.--Water-stage recorder, Parshall flume, and concrete control. Altitude of gage is 

6,600 ft (from topographic map). Prior to Oct. 1, 1942, at datum 1.00 ft lower and 

from Oct. 1, 1942, to Sept. 30, 1948, at datum 1.00 ft higher.

Extremes. Maximum discharge during year, 3.0 cfs July 9 (gage height, 2.05 ft); minimum 

daily, 0.4 cfs for many days.

1925-60: Maximum discharge, 2,040 cfs June 23, 1925 (gage height, 11.3 ft, present 

datum), siphon spillways operating at Huntington Lake; minimum daily recorded, 0.1 cfs 

Jan. 18-21, Aug. 21 to Sept. 24, Oct. 7-18, Dec. 5-16, 1931.

Remarks.--Records good. Flow regulated by Huntington Lake beginning in 1913 (see preceding page). During most of year flow is diverted for power development at Big Creek 

powerhouse No. 1.

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

Southern California Edison Co. in connection with a Federal Power Commission project.

Revisions (water years). WSP 1315-A; 1943(M). WSP 1635: 1925-29.

360 SAN JOAQUIN RIVER BASIN

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

Location. Lat 37°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 1960. Monthly discharge only for some periods, published in WSP 1315-A.

Gage. Water-stage recorder. Datum of gage is at mean sea level (levels by Topographic

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

bank and prior to Oct. 1, 1959, at datum 3.77 ft below mean sea level.

Average discharge. 23 years, 893 cfs (646,500 acre-ft per year).

Extremes. Maximum discharge during year, 1,160 cfs Feb. 12 (gage height, 59.50 ft); minimum, 10 cfs Nov. 8.

1944-60: Maximum discharge, 5,910 cfs Apr. 6, 1958 (gage height, 71.14 ft, datum 

then in use); minimum, that of Nov. 8, 1959.

Remarks. Records good. Natural flow of stream affected by storage reservoirs, groundwater withdrawals, diversions for irrigation, and imported water from Delta-Mendota 

Canal (see p. 424). 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 

1960 are given in WSP 1744.

3130. Delta-Mendota Canal at Tracy pumping plant near Tracy, Calif. 

(Formerly published as Delta-Mendota Canal near Tracy)

Location. Lat 37°47'45", long 121°35'05", in SW£SW£ sec.31, T.I S., R.4 E., at Tracy 

pumping plant at intake to canal, 6 miles southeast of Byron and 10 miles northwest of 

Tracy.

Records available. June 1951 to September 1960. Prior to October 1959, published as 

"near Tracy."

Gage.--Water-stage recorder on forebay, pressure gages on pump discharge lines, and operating time of pumps. Datum of gage is at mean sea level (levels by Bureau of Reclamation).

Average discharge. 9 years, 1,286 cfs (931,000 acre-ft per year).

Extremes.--1951-60; Maximum daily discharge, 4,418 cfs Feb. 9, 1957; no flow for many 

days in most years.

Remarks. Discharge computed from records of operation of pumps. Water is diverted from 

Sacramento-San Joaquin Delta by way of Old River and a dredged channel to the Tracy 

pumping plant where it is lifted about 200 ft into canal. Water, less intermediate 

diversions, flows into Mendota Pool on San Joaquin River to replace water diverted at 

Priant Dam. The canal is a part of Central Valley project. Records of chemical analyses for the water year 1960 are given in WSP 1744.

Cooperation. Records of daily discharge furnished by Bureau of Reclamation and reviewed 

by Geological Survey.

Dec. 9, 1930, in fender pier of railroad bridge at same datum. Water-stage recorder 

for station at Verona was used as auxiliary gage for this station January 1941 to 

June 1945. Since Aug. 16, 1945, auxiliary water-stage recorder 6.0 miles downstream 

from base gage.

Average discharge. 20 years (1940-60), 9,886 cfs (7,157,000 acre-ft per year).

Extremes.--Maximum discharge during year, 24,900 cfs Feb. 10 (gage height, 37.76 ft); 

maximum gage height, 37.88 ft Feb. 10; minimum daily discharge, 2,890 cfs Apr. 20; 

minimum gage height, 15.00 ft Dec. 12.

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

fall data, which are fair. Natural flow of stream affected by storage reservoirs, 

power developments, bypassing for flood control, diversions for irrigation, and considerable return flow from irrigated areas. Records of chemical analyses for the 

water year 1960 are given in WSP 1744.

512 SACRAMENTO RIVER BASIN 

3995. North Pork Feather River near Prattville, Calif.

Location. Lat 40°10'10", long 121 "OS'29", in SW^ sec.28, T.27 N., R.8 E., on left bank 

0.5 mile downstream from Almanor Dam, 4.5 miles (revised) southeast of Prattville, and 

9 miles upstream from Butt Creek.

Drainage area. 507 sq mi.

Records available. June 1905 to September 1960 (daily discharges for July 1921 to September 1936 Include water diverted through Almanor-Butt Creek tunnel). Records for water 

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 1924 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 (unpublished prior to 1936 and since 1959).

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 datums.

Average discharge. 55 years, 909 cfs (658,100 acre-ft per year), including diversion 

from Lake Almanor through Butt Creek tunnel.

Extremes. Maximum discharge during year, 46 cfs May 1 (gage height, 1.98 ft); minimum 

daily, 2.9 cfs Jan. 9, 10. Extremes do not include diversions through Butt Valley 

powerhouse.

1905-60: 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, 1958. 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, nine 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).

Extremes. Maximum discharge during year, 1,140 cfs Feb. 8 (gage height, 1.41 ft); no flow 

over dam for long periods.

1925-34, 1935-60: Maximum discharge, 6,800 cfs Dec. 11, 1937 (gage height, 4.18 ft), 

from rating curve extended above 1,500 cfs on basis of computation of peak flow over 

dam; practically all low flow diverted after May 23, 1928.

Remarks. Records good. Milton-Bowman tunnel (see preceding page) diverts above station 

to Bowman Lake (see p. 537 ). Flow regulated by Milton Reservoir, capacity, 900 acre-ft.

Cooperation. Water-stage recorder inspected by employees of Nevada Irrigation District.

1,000 ft upstream from Oregon Creek and 2 miles northeast of North San Juan.

Drainage area. 162 sq mi.

Records available. October 1940 to September 1960. Monthly and yearly discharges for 

water year 1941, published in WSP 1315-A. Prior to October 1949, published as Middle 

Pork Yuba River above Oregon Creek. If record for Oregon Creek near North San Juan is 

subtracted from record published as Middle Pork Yuba River near North San Juan, a record equivalent to that at this site can be obtained for the period 1910-41.

Gage. Water-stage recorder. Altitude of gage is 1,440 ft (from topographic map). 

Average discharge. 20 years, 364 cfs (263,500 acre-ft per year).

Extremes. Maximum discharge during year, 13,300 cfs Feb. 8 (gage height, 13.02 ft); minimum, 22 cfs Jan. 1.

1910-60: Maximum discharge, 26,400 cfs Dec. 22, 1955 (gage height, 17.25 ft), from 

rating curve extended above 8,200 cfs on basis of slope-area measurement at 15.25 ft; 

minimum, 10 cfs Jan. 3, 1950.

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

which are fair. Milton-Bowman tunnel (see p. 527) diverts above station to Bowman 

Lake (see p. 537); other small diversions above station.

Revisions. WSP 1395: Drainage area.

Location. Lat 39°14 I 22", long l21°16'00", in SW$SEj sec.14, T.16 N., R.6 E.,~on left"bank 

upstream from spillway of Englebright Dam, 1 mile upstream from Deer Creek and 2.5 mile 

northeast of Smartville.

Drainage area. 1,104 sq mi.

Records available. October 1941 to September 1960. Prior to October 1953, published as 

«at Narrows Dam." If record for Deer Creek near Smartville since 1941 is added to record at this site, a record equivalent to that published from 1903 to 1941 as Yuba River 

at Smartville can be obtained.

Gage. Water-stage recorder, flow meter in penstock and watt meters in powerhouse Just 

below dam. Datum of gage is at mean sea level (levels by Corps of Engineers). Prior 

to Sept. 19, 1958, at datum 526.99 ft higher.

Average discharge. 19 years, 2,576 cfs (1,865,000 acre-ft per year).

Extremes. Maximum discharge during year, 86,000 cfs Feb. 8, including flow through powerhouse; no flow Nov. 1-2.

1941-60: Maximum discharge, 148,000 cfs Dec. 23, 1955, including flow through 

powerhouse, from rating curve extended above 25,000 cfs on basis of computation of peak 

flow over spillway of dam; no flow at times during 1942, 1949, 1956, 1958-60.

Remarks. Records good. Diversions for power and irrigation above station. Up to 250 cfs 

can~bypass station and up to 670 cfs can be diverted into Bear River basin. Flow regulated by Lake Spaulding beginning in 1912 (capacity, 74,500 acre-ft), Englebright Reservoir beginning in 1941 (capacity, 70,000 acre-ft), Bowman Lake (see p. 537), Fordyce 

Lake beginning in 1926 (capacity, 46,700 acre-ft), and many smaller reservoirs. Records given herein show total flow over Englebright Dam spillway and through and past 

powerplant.

Cooperation. Records of flow through powerplant furnished by Pacific Gas & Electric Co.

SACRAMENTO RIVER BASIN 54V 

4210. Yuba River near Marysville, Calif.

Location. Lat 39°10'35", long 121°31'25", on left bank in New Helvetia land grant,

4.2 miles northeast of Marysville, Yuba County, and 5 miles downstream from Dry Creek.

Drainage area.--1.335 sq ml.

Records available. October 1940 to September 1960 (1940-43, 1945, low-water periods only). 

Published as "at Marysville 11 October 1940 to September 1957. Records published for 

two sites August 1954 to September 1955. Yearly discharge for the 1945 water year 

published in WSP 1315-A.

Gage. Water-stage recorder. Gage is set to datum of Corps of Engineers. Prior to

Oct. 1, 1956, at Simpson Lane Bridge in Marysville 4.2 miles downstream at same datum. 

Gages operated simultaneously at Simpson Lane Bridge and at present site August 1954 

to September 1955. Oct. 1, 1956, to Sept. 30, 1957, at site 4.2 miles downstream at 

same datum.

Average discharge. 17 years (1943-60), 2,612 cfs (1,891,000 acre-ft per year).

Extremes. Maximum discharge during year, 71,200 cfs Feb. 8 (gage height, 84.65 ft); 

minimum not determined, probably occurred during period of no gage-height record.

1943-60: Maximum daily discharge, 136,000 cfs Dec. 23, 1955; maximum gage height, 

82.5 ft probably Dec. 23, 1955 (at former site), from floodmarks.

1940-60: Minimum discharge recorded, 10 cfs July 2, 1959.

Revisions. The figure of maximum gage height for the water year 1956, at present 

site, as published in WSP 1565, has been found to be in error and should not be used.

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

Flow regulated by several reservoirs above station. Many diversions above station 

for power. Diversions for irrigation of about 13,000 acres between stations at 

Englebright Dam and near Marysville.

Discharge, in cubic feet per second, water year October 1959 to September I960

Average discharge. 19 years, 820 cfs (593,700 acre-ft per year).

Extremes. Maximum discharge during year, 26,300 cfs Feb. 8 (gage height, 7.57 ft); minimum, 

22 cfs Sept. 23.

1941-60: 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. Records of water temperatures for the water year 1960 are given in

bank 400 ft upstream from Iowa Canyon Creek, 1.1 miles downstream from intake of American River flume, and 2.8 miles northwest of Camino.

Drainage area. 497 sq mi.

Records available. October 1922 to September 1960. Monthly discharge only for October 

1922, published in WSP 1315-A. Prior to October 1956, records for river and American 

River flume published separately.

Gage.--Water-stage recorder. Altitude of gage is 1,630 ft (from topographic map). Nov. 1, 

T950, to Dec. 5, 1951, staff gage at same site and datum.

Average discharge. 37 years (1922-59, prior to regulation by Ice House Reservoir), 961 cfs 

(695,700 acre-ft per year), combined flow of South Pork American River near Camino and 

American River flume.

Extremes (river only) . Maximum discharge during year, 10,200 cfs Feb. 8 (gage height, 

14.82 ft); minimum daily, 5.7 cfs Jan. 3.

1922-60: Maximum discharge, 49,800 cfs Dec. 23. 1955 (gage height, 32.6 ft, from 

floodmarks), from rating curve extended above 24,000 efs on basis of computation of 

peak flow over dam; minimum daily, 1.3 cfs Aug. 24, 1931.

Remarks. Records good. Records of daily discharge given herein include flow of American 

River flume which diverts 1.1 miles above station, from right bank of South Pork American River in sec.24, T.ll N., R.ll E., for power development; water is returned to 

river at Rock Creek powerhouse 5.4 miles below station. Plow partly regulated by five 

reservoirs (total usable capacity, 82,900 acre-ft). See records for Ice House Reservoir, page 580. Echo Lake conduit (see p. 573) imports up to 2,000 acre-ft each year 

from Truckee basin. Water diverted by El Dorado Canal used for power and returned to 

river above station except for a variable amount up to 40 cfs, May to October, and 

about 7 cfs for remainder of year, which is used for irrigation and domestic use in 

vicinity of Placerville.

Cooperation. Water-stage-recorder graph and 10 discharge measurements, and for the flume, 

water-stage-recorder graph and 8 discharge measurements furnished by pacific Gas & Electric Co. in connection with a Federal Power Commission project.

* Discharge measurement or observation of no flow made on this day.
598 SACRAMENTO RIVER BASIN

4530. Yolo bypass near Woodland, Calif.

Location.--Lat 38°40'40", long 121°38'35", on left bank just upstream from Sacramento and 

Woodland railroad bridge, 6 miles upstream from Sacramento bypass, 7 miles downstream 

from Fremont weir, and 7 miles east of Woodland, Yolo County.

Records available. October 1939 to September 1960. Monthly discharge only for some periods, published in WSP 1315-A.

Gage. Water-stage recorder. Gage is set to datum of Corps of Engineers. Prior to

Dec. 17, 1941, staff gage and Dec. 18-31, 1941, water-stage recorder, at datum 0.73 ft 

higher. Supplementary water-stage recorder 6 miles downstream at same datum.

Average discharge. 21 years, 4,193 cfs (3,036,000 acre-ft per year).

Extremes. Maximum discharge during year, 73,600 cfs Feb. 9 (gage height, 27.06 ft); minimum, 0.8 cfs Nov. 1.

1939-60: Maximum discharge, 272,000 cfs Feb. 8, 1942 (gage height, 32.00 ft); no 

flow at times in 1939-40.

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

stage-discharge relation, which are poor. Flow is that from Cache Creek and Knights 

Landing Ridge Cut plus floodwater passing over Fremont weir; during summer, flow consists largely of return water from irrigation. Records of suspended sediment loads for 

the water year 1960 are given in WSP 1744.

Discharge, In cubic feet per second, water year October 1959 to September I960

500 ft dovmatream from Van Arsdale Dam and 5 miles north of town of Potter Valley.

Drainage area. 347 sq mi.

Recordsi available. November 1909 to September 1922 (combined monthly discharge only, of 

Eel River at this station and Snow Mountain Water & Power Co.'s tailraee near Potter 

Valley), October 1922 to September 1960. Monthly discharge only for some periods, published in WSP 1315-B. Prior to October 1929, published as South River at Van Arsdale 

Dam, near Potter Valley.

Gage. Water-stage recorder. Altitude of gage is 1,400 ft (from topographic map). Nov. 18, 

T909, to Mar. 3, 1927, recorder in reservoir 800 ft upstream from Van Arsdale Dam at 

different datum. Oct. 1, 1927, to Feb. 28, 1937, staff gage at present site and datum.

Average discharge. 51 years (1909-60), 612 cfs (443,100 acre-ft per year), combined flow 

of Eel River at Van Arsdale Dam and Potter Valley powerhouse tailraee.

Extremes. Maximum discharge during year, 29,700 cfs Feb. 8 (gage height, 22.30 ft); minimum daily, 1.8 cfs Nov. 16, 20, 22.

4860. Lost River diversion canal near Olene, Oreg.

Location (revised) . Lat 42"08'3S", long ISl^O'SO", in SE$SVf£ sec. 29, T.39 S., R.10 E., 

on right bank at headgates, 3.0 miles southwest of Olene.

Records available . May 1912 to September 1915, January 1916 to June 1917, October 1917 

 to April 1918, October 1918 to May 1919, October 1919 to September 1960. Published as 

"near Klamath Palls" 1916-18.

 daily. Al , . . , ,

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. 44 years (1912-15, 1919-60), 159 cfs (115,100 acre-ft per year). 

Extremes. 1912-60: 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

 glfUes 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 1960 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 1960 pumpage (from Lost River source) 

amounted to 4,850 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. 678).

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

5075. Link River at Klamath Falls, Oreg.

Location (revised). Lat 42°13'25", long 121°47'35", in SW^NW£ sec.32, T.38 S., R.9 E., 

on left bank 600 ft upstream from outlet of Keno Canal and 0.4 mile upstream from 

Main Street Bridge (U. S. Highway 97} 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 1960.

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 daturns. Sept. 14, 1912, to Nov. 23, 1923, 

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

Average discharge.- 56 years, 1,616 cfs (1,170,000 acre-ft per year).

Extremes. Maximum discharge during year, 2,640 cfs Apr. 10; minimum daily, 384 cfs 

Apr.9.

1904-60; 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. 675). Many 

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

which,since September 1908, 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.

678 KLAMATH RIVER BASIN

5085. Diversion from Klamath River to Lost River, near Olene, Oreg.

Location (revised). Lat 42°08'25", long 121°41'20", in NE£NW$ sec.31, T.39 S., R.10 E., 

>n south bank of Lost River diversion canal, 0.5 mile east of bridge on State Highway 39, 0.9 mile downstream from dam on Lost River, and 3.8 miles southwest of Olene.

Records available. April 1931 to September 1960. Published with records for Lost River 

diversion canal near Olene in 1931.

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

Average discharge. 30 years, 33.4 cfs (24,180 acre-ft per year).

Extremes. 1931-60; 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 Tule Lake (see record for Lost River diversion canal near Olene, p. 667). 

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 pumped from the diversion canal by Miller Hill 

pumping plant (capacity, 70 cfs); during period June to August 1960 pumpage amounted to 

6,250 acre-ft.

Cooperation. Records furnished by Bureau of Reclamation.
