SCOPE OF WORK

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

water year ending September 30, 1954. Since 1888, when the United States Geological 

Survey first studied streamflow in relation to problems of irrigation, similar measurements have been made at more than 13,050 gaging stations in the 48 States and at many 

others in the Territories of Alaska and Hawaii. On September 30, 1954, the Geological 

Survey and cooperating organizations were maintaining 6,750 gaging stations, including 

those in Alaska and Hawaii. Discharge measurements only were made at many other points in 

the 1954 water year, most of which are published at the end of this report.

COOPERATION

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

of Public Works, F. B. Durkee, director, through Division of Water Resources, A. D. Edmonston, State engineer; Contra Costa County; Orange County Flood Control District; Sacramento Municipal Utility District; San Luis Obispo County Flood Control and Water Conservation 

District; cities of San Diego and Santa Barbara; and Santa Barbara County Water Agency. 

In Oregon the work was done under cooperative agreement with the State of Oregon, C. E. 

Stricklin, State engineer.

Assistance in the form of funds or services was given by the Corps of Engineers, Department of the Army, in collecting records published herein for 42 gaging stations, by 

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

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

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

Tuolumne River basin made for the Hetch Hetchy project and of the flow of Alameda Creek 

near Niles was borne by the city and county of San Francisco.

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

Oregon Power Co., Southern California Edison Co., Pacific Gas & Electric Co., Kings River 

Water Association and Madera, Merced, Modesto, Nevada, Turlock, Oakdale, Oroville-Wyandotte, South San Joaquin, and Woodbridge Irrigation Districts; in Oregon, The California 

Oregon Power Co.

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 

several States were collected and prepared for publication in the district offices listed 

below.

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

records of discharge prior to publication, and other unpublished data concerning the gagingstation records may usually be obtained from the district office.

DEFINITION OF TERMS AND ABBREVIATIONS

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

as follows:

Cubic foot per second (cfs) is the rate of discharge of a stream whose channel is 

1 square foot in cross-sectional area and whose average velocity is 1 foot per second.

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

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

is distributed uniformly in time and area.

Runoff in inches is the depth to which an area would be covered if all the water draining from it in a given period were uniformly distributed on its surface. The term is used 

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

Acre-foot is the quantity of water required to cover an acre to the depth of 1 foot 

and is equivalent to 43,560 cubic feet. The term is commonly used in relation to storage 

for irrigation.

Cfs-day is the volume of water represented by a flow of 1 cubic foot per second for 

24 hours. It is equivalent to 86,400 cubic feet, 1.983471 acre-feet, or 646,317 gallons, 

and represents a runoff of 0.0372 inch from 1 square mile,

Stage-discharge relation is the relation between gage height and the amount of water 

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

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

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

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

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

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

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

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

within the area unless otherwise noted.

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

published reports.

DOWNSTREAM ORDER OF LISTING GAGING STATIONS

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

order of listing gaging-station i-ecords 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
EXPLANATION OF DATA 3

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.

EXPLANATION OF DATA ""'"

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

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

weather records, and other information are used to supplement base data in determining the 

daily flow. The records of stage are obtained either from direct readings on a nonrecording gage or from a water-stage recorder that gives a continuous record of fluctuations. 

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

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

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

are shown in figure 1.

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

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

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

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

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 and 

runoff 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 1954 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 

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 

daturas 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 fame 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

385737 O -56 -Z
6 SUPPLY WATER SUPPLY, 1954, PART 11

as follows: "(M)" means that only the instantaneous maximum'discharge was revised; "(m)" 

that only the instantaneous minimum was revised; and "(P)" that only peak discharges were 

revised. If the drainage area has been revised, the report in which'the revised figure 

was first published is given. It should be noted that for all stations for which cubic 

feet per second per square mile and runoff in inches are published, a revision of the 

drainage area necessitates corresponding revision of all figures based on the drainage 

area. Revised figures of cubic feet per second per square mile and runoff in inches resulting from a revision of the drainage area only are usually not published in the annual 

series of reports.

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

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

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

day of its occurrence.

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

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

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

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

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

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

than 20 inches.

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

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

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

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

peaks above the selected base are given. The base discharge, which is given in parentheses, is selected so that an average of about three peaks a year will be presented. 

Peak discharges are not published for canals, ditches, drains, or for any stream for which
PUBLICATIONS 7

the peaks are subject to substantial control by man.

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

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

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

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

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

For most gaging stations on lakes and reservoirs the data presented comprise a description of the station and a monthly summary table of stage and contents. For some reservoirs 

a table showing daily contents or stage is given. A skeleton table of capacity at given 

stages is usually given In the first report in which data for the reservoir are published, 

but it is omitted from succeeding reports.

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 dally records.

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

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

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

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

storage or diversion records are included to indicate the extent of the regulation or diversion, or unless satisfactory adjustments can be made for changes in Contents of reservoirs or for other changes incident to use and control. Evaporation from a reservoir is 

not included in the adjustments for changes in reservoir contents, unless it is so stated. 

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

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

comparison with the observed discharge.

Many gaging stations on streams in the irrigated areas of the United States are situated above most of the diversions from those streams, and therefore the discharge recorded 

does not actually show the water supply available at the stations for further development, 

because water must first be supplied to existing Irrigation systems.

PUBLICATIONS

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

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

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

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

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

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

Note. WSP 296, 299, 3OO contain records of flow at all gaging stations in Part 11 from the be6inning of records through June 30, 1912. They supersede records published in the 10th to 22nd 

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

The records at most of the stations discussed in these reports extend over many years. 

Discharge measurements at many points other than regular gaging stations have been made 

each year and are published under "Miscellaneous discharge measurements" at the end of 

each report. The streams and points of measurement are listed in ths same order as the 

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

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

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

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

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

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

Reports also have been published that are compilations of records for various areas, 

usually a single State or drainage basin. These reports contain records previously published (some of which may have been revised), as well as some records not contained in the 

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

the Pacific slope basins in California.

HYDROLOGIC CONDITIONS

The water year 1954 was characterized by below normal runoff in the southern portion 

to well above normal in the northern portion of the Pacific slope basins in California. 

Some flooding occurred during November and January in Oregon and northern California; peak 

discharges approached but did not exceed previous record-highs. For three key gaging 

stations in the area covered by this report, a comparison of the monthly and yearly mean 

discharge during the 1954 water year with the median discharge for the 25-year period 

1921-45 is shown in figure 3 on the following page.

SWEETWATER RIVER BASIN

Sweetwater River at Sweetwater Dam, Calif.

Location.--Lat 32°41 I 20", long. 1170 00'35",.in La Nacion Grant, at Sweetwatep Dam, 6 miles 

east of National City, San Diego County, and 8 miles upstream from mouth.

Drainage area. 181 sq ml.

Records available. October 1887 to September 1954.

Gage. Staff gage read once daily. Datum of gage is 149.08 ft above mean sea level, datum 

of 1929.

Remarks.--Records of inflow represent all water reaching Sweetwater Reservoir, including 

rainfall on reservoir and imported Colorado River water. Total inflow is computed on 

basis of records of storage, release (draft), spill, leakage, and evaporation. Colorado River water delivered to this reservoir through aqueduct of San Diego County Water 

Authority, as shown in table, is included in figures of total inflow but is excluded 

from figures of runoff from Sweetwater River basin. The first water from Colorado 

River reached this reservoir on Apr. 16, 1948. Capacity and area ratings for reservoir 

are dated December 1947. Capacity of reservoir at spillway level (gage height, 89.70 

ft), 27,689 acre-ft. Dead storage, 4 acre-ft below lowest outlet at gage height 19.7 

ft, included In these records. No diversion above reservoir. Regulation by Loveland Reservoir (see preceding page). Water is released as required for irrigation and domestic 

use in Chula Vista, National City, and contiguous areas.

Note. The runoff from the basin of Sweetwater River Is equal to the algebraic sum of (1) change 

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

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

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

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

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

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

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

Note. Runoff from basin of San Vicente Creek is equal to algebraic sum of (l) change in contents, 

(2) draft, (3) evaporation, and (4) spill plus leakage, minus (5) the quantity imported from Colorado River and Santa Ysabel Creek. However, computation of runoff from San Vicente Creek basin 

using figures in above table gives results that may be in error, frequently being negative. This 

arises primarily from the difficulty of computing runoff from San Vicente Creek basin as the 

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

necessary to produce a final answer within reasonable limits of accuracy. The natural runoff from 

this basin during the year was very small.
30 SAN DIEGO RIVER BASIN

San Diego River near Santee, Calif.

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

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

Drainage area. 380 sq mi.

Records available. May 1912 to September 1954 (incomplete prior to 1920).

Gage.--Water-stage recorder and unfinished rubble dam control. Altitude of gage is 205 ft 

"from topographic map). Prior to Nov. 10, 1920, staff gage at site l£ miles upstream 

at different datum.

Average discharge. 39 years (1912-15, 1917-18, 1919-54), 30.3 cfs (21,940 acre-ft per 

year); median of yearly mean discharges, 5.1 cfs (3,690 acre-ft per year).

Extremes. Maximum discharge during year, 658 cfs Mar. 25 (gage height, 2.23 ft); no flow 

ror several months.

1912-54: 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 during most 

years.

Remarks. Records fair. Discharge measurements generally made twice a month. Small flows 

of less than 0.05 cfs, from rising water at the gage, have been called zero. Flow regulated by El Capitan, Cuyamaca, and San Vicente Reservoirs (see pp. 28,27,29). Diversions 

above station by city of San Diego for municipal supply and by La Mesa, Lemon Grove, and 

Spring Valley Irrigation District.

Records available.--December 1912 to September 1928, October 1936 to September 1954., 

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

Gage.--Staff gage read once daily after Mar. 7 ( 1954. 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, at site 

1 mile downstream at different datum.

Average discharge. 33 years (1913-28, 1936-54), 16,430 acre-ft per year (22.7 cfs); 

median of yearly mean discharges, 9,410 acre-ft per year (13.0 cfs).

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

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

leakage, and evaporation. 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), 29,684 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.

2 W . , on right bank. 800 ft upstream from Lake Hodges Dam and 6.2 miles southwest of 

Esoondido.

Drainage area.--303 sq mi.

Records available. January 1916 to September 1954. 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. Pri-oi 

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

Gage.

to

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

on the lake, computed on basis of records of storage, release (draft), spill, leakage, 

and evaporation. Capacity and area ratings for lake are based on a resurvey in 1948. 

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. Diversions for irrigation above Lake Hodges. Water drawn from Lake Hodges 

passes through a conduit to San Dieguito reregulating reservoir, from which it is released as required for municipal use. Flow regulated since July 1954 by Sutherland 

Reservoir (capacity, 29,000 acre-ft).

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

t On first day of month.

Note. No imported Colorado River water or pumped ground water entered the reservoir during 

the calendar year 1953 or the water year 1953-54. For months when inflow to the reservoir was 

small and other elements were large, discordant figures of runoff may appear. This arises 

primarily from the difficulty of computing runoff from the basin as the residual of several 

larger quantities which are not susceptible of measurement with a precision necessary to produce 

a final answer within desirable limits of accuracy.
SAN LUIS REY RIVER BASIN 39

San Luis Key River at Lake Henshaw, near Mesa Orande, Calif.

Location.--Lat 33°14'15", long. 1160 45'50", in NW£ sec. 10, T. 11 S., R. 2 E., at Henshaw 

Dam, 5 miles north of Mesa Grande.

Drainage area. 209 sq mi.

Records available. January 1923 to September 1954. October 1911 to January 1923 at site 

1 mile downstream published as "near Mesa Grande;" records not equivalent due to evaporation from Lake Henshaw.

Gage. Staff gage read once daily.

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

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

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

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

32 years (1922-54), 23,300 acre-ft per year (32.2 cfs) inflow to Lake Henshaw, exclusive of 90 percent of rainfall on lake surface; median of yearly inflow, 15,100 acreft per year (20.9 cfs).

Remarks. Records of runoff represent all water reaching Lake Henshaw, exclusive of 90 percent of rainfall on water surface of lake and supplemental water obtained by pumping 

ground water from area adjacent to lake, computed on basis of records of storage, 

release (draft), spill, leakage, evaporation, rainfall, and ground-water pumpage. Capacity and area ratings for lake are based on resurvey made in October 1951. Capacity 

of reservoir at spillway level (gage height, 107.00 ft), 194,300 acre-ft. No dead 

storage. Since storage of water was begun, runoff as computed has been exclusive of 

90 percent of rainfall on water surface of lake. During the year the amount of rainfall excluded was 1,745 acre-ft. No diversion above Lake Henshaw. No flow over spillway since dam was completed. Water is released down San Luis Rey River for diversion 

downstream for Irrigation, power, and domestic use.

Cooperation. Basic records furnished by Vista Irrigation District.

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

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

area adjacent to lake is subtracted from inflow to obtain runoff. However, as thus computed the 

results may be in error. This arises primarily from the difficulty of computing runoff from basin 

as the residual of several larger quantities which are not susceptible of measurement with a precision necessary to produce a final answer within reasonable limits of accuracy.
SAN LUIS REY RIVER BASIN

San Luis Rey River below Pala diversion dam, near Pala, Calif.

Location.--Lat 33°21'30 11 , long. 117°02'50", in SWir sec. 25, T. 9 S., R. 2 W., on right

Records available.--October 1948 to September 1954. January 1923 to September 1948 at 

site 300 ft downstream, published as "at Nigger Canyon, near Temecula"; records not 

equivalent owing to change in natural water loss resulting from creation of Vail Lake. 

October 1948 to September 1951, published as "at Nigger Canyon, near Temecula"; records are for draft and spill only from Vail Lake.

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

b~y Bureau of Reclamation). Prior to Oct. 16, 1930, at about same site at several different datums. Oct. 16, 1930, to September 1948, at site 300 ft downstream at different datum.

Average discharge.--25 years (1923-48), 10,580 acre-ft per year (14.6 cfs); 6 years 

(1948-54), 47490 acre-ft per year (6.20 cfs).

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

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

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

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

storage, 4 acre-ft below lowest outlet at gage height 3.5 ft, included in these records. Water is released down Temecula Creek for diversion about 1 mile below dam as 

required.

rating curve extended above 150 cfs by logarithmic plotting; minimum daily, 0.2 cfs 

for several days during October, June, July, and September.

1924-54: Maximum discharge, 33,100 cfs Feb. 16, 1927 (gage height, 15.6 ft), by 

slope-area method; minimum daily, 0.1 cfs at times during 1929, 1951, and 1953.

Remarks. Records good except those for periods of fragmentary gage-height record and 

discharge above 200 cfs, which are fair. Discharge measurements generally made daily 

except Sundays. Flow partly regulated by Vail Reservoir (capacity, 50,000 acre-ft) 

beginning in November 1948. Several small diversions above station for irrigation. 

The Fallbrook Public Utility District pumped 945 acre-ft of water from a well in the 

stream bed 2,000 ft upstream from station during the water year.

Cooperation.--Gage-height record and 303 discharge measurements furnished by Santa Margarita rtanch (U. S. Navy) and Pauba Ranch.

basis of slope-area determination of peak discharge; minimum daily, 0.6 cfs Oct. 3, 

8, 9.

1919-54: Maximum discharge, 3,360 cfs Mar. 2, 1938, based on rainfall-runoff 

studies; practically no flow at times during 1929 and 1931-35.

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

silage-discharge relation, which are poor. Discharge measurements generally made twice 

a month during summer and once a week during rest of year. One small diversion above 

station for domestic supply.

76 SANTA ANA RIVER BASIN

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

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

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

Creek.

Records available. January 1929 to September 1954.

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

Riverside County engineer). Prior to Nov. 15, 1943, water-stage recorder 1$ miles upstream at different datum. During this period temporary stations were maintained at 

different sites and daturas within a quarter of a mile of the permanent gage. Nov. 15, 

1943, to Aug. 31, 1954, at datum 1.00 ft higher.

Extremes. Maximum discharge during year, 3,650 cfs Jan. 25 (gage height, 3.55 ft); minimum daily, 25 cfs Jan. 17.

1929-54: Maximum discharge, 100,000 cfs Mar. 2, 1938, on basis of slope-area determination of peak discharge; minimum daily, 20 cfs for several days during August and 

September 1947.

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

sTage-discharge relation, which are fair. Discharge measurements are generally made 

once a week. Plow regulated by Big Bear Lake (see p. 53). Natural flow of stream 

affected by ground-water withdrawals and diversions for irrigation and return flow from 

irrigated areas. The Metropolitan Water District of Southern California released 

61,048 acre-ft of Colorado River water into Santa Ana River about 1.1 miles above station during year.

Discharge, in cubic feet per second, water year October 1953 to September 1954

SANTA ANA RIVER BASIN 77

Day Creek near Etiwanda, Calif.

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

0.2 mile downstream from confluence of 2 main forks and 6 miles north of Etiwanda.

Drainage area. 4.8 sq mi, approximately.

Records available. January 1929 to September 1954. Combined creek and diversion, October 

1950 to September 1954.

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

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

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

datum.

Average discharge. 25 years, 4.19 cfs (3,030 acre-ft per year); median of yearly mean 

discharges, 3.2 cfs (2,320 acre-ft per year).

Extremes . Maximum discharge during year, 242 cfs Jan. 25 (gage height, 3.28 ft), from 

rating curve extended above 120 cfs by logarithmic plotting; minimum daily, 0.2 cfs 

Oct. 1-20.

1929-54: Maximum discharge, 4,200 cfs Mar. 2, 1938, based on rainfall-runoff 

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

Remarks. Records good below 20 cfs and fair above except those for periods of no gageheight record, which are poor. Discharge measurements generally made twice a month. 

Etiwanda Water Co. diverts water above station. For records of combined discharge of 

creek and diversion, see following page. In addition, an infiltration gallery, 

unwatering gravel in bed of stream at gaging station, produced 620 acre-ft during year, 

and 140 acre-ft was diverted above station for spreading.

SANTA ANA RIVER BASIN 79

Santa Ana River at Hamner Avenue, near Corona, Calif.

Location.--Lat 33°56'50", long. 117°33'30", in Jurupa Grant, on left bank 300 ft downstream 

from Hamner Avenue Bridge, 5 miles north of Corona, Riverside County, and 5 miles upstream from Temescal Creek.

Records available. May 1930 to November 1954 (irrigation seasons only).

Gage. Water-stage recorder. Altitude of gage is 570 ft (from topographic map). Prior to 

Hay 1, 1946, water-stage recorder at several sites within 1 mile of present site at 

various datums.

Remarks. Records good. Discharge measurements generally made six times a month. Flow 

regulated by Big Bear Lake (see p. 53). Natural flow is affected by ground-water withdrawals, diversions for irrigation, and return flow from irrigated areas. Flow past 

station includes Colorado River water released to the Santa Ana River by Metropolitan 

Water District of Southern California (see Santa Ana River at Riverside Narrows, near 

Arlington).

Cooperation. Twenty-two discharge measurements furnished by Orange County Flood Control 

District, through P. H. Budd, flood-control engineer.

t Result of discharge measurement.
80 SANTA ANA RIVER BASIN

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

Location.--Lat 33°55'30", long. 117°35'40", in Jurupa Grant, on right bank 50 ft upstream 

from Auburndale Bridge on River Street, 2 miles upstream from Temescal Creek, and 4 miles 

northwest of Corona, Riverside County.

Records available. May 1930 to November 1954 (irrigation seasons only).

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

1929 (levels by Orange County Flood Control District). Prior to May 1946, at various

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

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

Discharge measurements generally made six times a month. Plow regulated by Big Bear 

Lake (see p. 53). The natural flow is affected by ground-water withdrawals, diversions 

for irrigation, and return flow from irrigated areas. Plow past station includes Colorado River water released to the Santa Ana River by Metropolitan Water District of 

Southern California (see Santa Ana River at Riverside Narrows, near Arlington). Water 

diverted into Durkee ditch, a quarter of a mile above station, bypasses station; discharge measurements, in cubic feet per second, of ditch from April to December 1954 are

 Engineers benchmark). Prior to Feb. 15, 1927, water-stage recorder at site about 150 

ft upstream at different datum. Feb. 15, 1927, to December 1929, staff gage at same 

site at different datum. December 1929 to Feb. 6, 1937, water-stage recorder at same 

site at different datum. Feb. 7, 1937, to Jan. 23, 1948, staff gage at same site at 

various daturns.

Average discharge. 31 years (1921-25, 1927-54), 20.3 cfs (14.700 acre-ft per year); median

 of yearly mean discharges, 8.0 cfs (5.790 acre-ft per year). Average combined discharge, 

river, canals, and pipeline, 6 years (1948-54), 17.9 cfs (12,960 acre-ft per year).

Extremes. Maximum discharge during year, 786 cfs Jan. 25 (gage height, 6.05 ft); no flow 

during several months.

1920-54: Maximum discharge, 45,000 cfs Feb. 16, 1927, on basis of slope-area determination of peak flow; no flow during several months of each year.

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

 Discharge measurements generally made twice a month. Flow partly regulated by Hemet 

Reservoir (capacity, 13,400 acre-ft); contents, 818 acre-ft Sept. 30, 1954, representing 

net decrease of 312 acre-ft during year. For records of combined daily discharge of San

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

Location.--Lat 33°47'10", long. 117 0 43'35", in Lomas de Santiago Grant, on upstream face 

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

Park, Orange County.

Drainage area. 63 sq mi, approximately.

Records available. October 1931 to September 1954.

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

Average discharge. 23 years, 13,630 acre-ft per year (18.8 cfs); median of yearly mean 

discharge, ?7800 acre-ft per year (10.8 cfs).

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

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

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

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

spillway level (gage height, 790.0 ft), 25,000 acre-ft. Dead storage below lowest outlet included in these records. Water released to conduits as required for irrigation is 

called draft; water released back to creek is called waste. Spill, waste, and leakage, 

combined, represent all water passing down Santiago Creek from Santiago Dam. Minor 

diversions in basin above this reservoir.

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

Irrigation Districts and Irvine Co.

SAN GABRIEL RIVER BASIN 97

San Gabriel River near Azusa, Calif.

Location. Lat 34°10'10", long. 117°53'16", in SW£ sec. 13, T. 1 N., R. 10 W., on right 

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

Drainage area. 211 sq mi.

Records available. May 1894 to September 1954.

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

"Thgeles County Flood Control District benchmark). Prior to August 1917, staff gages and 

August 1917 to Sept. 30, 1937, water-stage recorders, at several sites from 1? to 2 miles 

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

site half a mile downstream at different datum. Feb. 22, 1938, to Feb. 7, 1939, waterstage recorder at site a quarter of a mile upstream at different datum. Datum lowered 

4.35 ft May 9, 1950.

Average discharge. Average natural discharge of river, adjusted for diversions, importations, regulation, and evaporation in Cogswell, San Gabriel, and Morris Reservoirs, 59 

years (1895-1954), 156 cfs (112,900 acre-ft per year); median of yearly mean natural 

discharges, 115 cfs (83,260 acre-ft per year).

Extremes. Maximum discharge during year, 9,420 cfs Apr. 16 (gage height, 12.32 ft, highwater mark in gage well), from rating curve extended above 4,200 cfs by logarithmic 

plotting; no flow during several months.

1894-1954: 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 fair except those for Jan. 25 to Apr. 8, which are poor. Flow regulated

 EJJTogswell and San Gabriel 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 about 3 miles above station. The Metropolitan Water District of Southern California reports a discharge of 1,110 acre-ft of Colorado River water into San 

Gabriel River below Morris Dam and above station during October, November, and July. 

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

actual flow in river and Azusa canal, adjusted for storage and evaporation in Cogswell, 

San Gabriel, and Morris Reservoirs, as shown in table below. These figures of runoff 

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

Co.'s canal as published from 1894 to 1933.

150 SANTA YNEZ RIVER BASIN

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

Location. Lat 34°2&'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. 16.0 sq mi (not including Alder Creek).

Records available. December 1930 to September 1954. Prior to October 1938, published 

as "at Juncal Reservoir, near Montecito."

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

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

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

used for works in this vicinity.

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

rainfall on lake, computed on basis of records of storage, diversion to city of Montecito (draft), spill and release to river, and evaporation. Records of net runoff 

exclude rainfall on water surface, computed on basis of area and records of precipitation. Capacity and area ratings for this lake are based on surveys made in 1948. Lake 

capacity at spillway level (gage height, 225.0 ft), 6,760 acre-ft. Dead storage, 268 

acre-ft, below lowest outlet at gage height 139.0 ft, included in these records. Records are computed as of 6 p.m. on last day of each month. Ther.e is no regulation or 

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

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

Jameson Lake, and is included in these records.

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

Water District.

Note. For months when inflow to the reservoir was small and other elements were relatively large, 

negative or discordant figures of inflow or runoff may appear. To the extent that such discrepancies 

may be attributed to inaccuracies in the capacity rating, quantities too small for periods of falling stage in the reservoir are compensated by quantities too large for periods of corresponding 

rising stage. Inaccuracies In figures of draft or evaporation, which may be within reasonable 

limits in these figures, may result In disproportionately large Inaccuracies in small figures of 

inflow or runoff computed as residuals.
SANTA YNEZ RIVER BASIN 151

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

Location. Lat 34°31'37", long. 119 0 41'10" ) on upstream side of Gibraltar Dam, 7 miles

control tower near left abutment of main dam on Kern River, 1.5 miles north of new town 

of Isabella and 2.8 miles upstream from Erskine Creek.

Drainage area. 2,080 sq mi, approximately.

Records available. October 1953 to September 1954.

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

Extremes.--Maximum contents during year, 85,380 acre-ft June 9 (elevation, 2,543.60 ft); 

minimum, 296 acre-ft Oct. 4, 7, 9, 10 (elevation, 2,470.67 ft).

Remarks. Reservoir is formed by earth-fill dam with side-hill spillway and auxiliary

earth-fill dam, completed in 1954; regulation of discharge from reservoir began Apr. 15, 

1954. Minor detention storage occurred during construction of dam prior to this date, 

the maximum being 1,750 acre-ft on Apr. 27, 1953. Usable capacity, 551,800 acre-ft between elevations 2,470.0 ft (invert of main outlet) and 2,605.5 ft (spillway crest) 

above mean sea level. Dead storage, 266 acre-ft. Surcharge flood-control storage, 

268,200 acre-ft between ungated spillway crest and elevation 2,627.0 ft (maximum design 

spillway flood pool). Records, including extremes, show total contents at 12 p.m. 

Water is released to Kern River through tunnel in left abutment of main dam and to

Kings River above North Fork, Calif.

Location (revised) . Lat 36°51'45", long. 119°07'25", in NE£ sec. 27, T. 12 S., R. 26 E., 

on left bank at Rogers Crossing, 0.9 mile upstream from North Fork and 2.9 miles south 

of Balch Camp.

Drainage area. 956 sq ml.

Records available. March 1927 to December 1928, October 1931 to September 1954.

Gage. Water-stage recorder. Datum of gage is 1,003.5 ft above mean sea level (from riverprofile survey). March 1927 to December 1928, at site 0.5 mile downstream at different

datum.

Average discharge. 24 years (1927-28, 1931-54), 1,415 cfs (1,024,000 acre-ft per year).

Extremes. Maximum discharge during year, 8,370 efs May 19 (gage height, 6.33 ft); mlnlmum, 114 cfs Sept. 27.

246 TULARE LAKE BASIN

Kings River below North Fork, Calif.

Location. Lat 36°52'30", long. 119°08'30", in NE& sec. 21, T. 12 S., R. 26 E., on right 

bank 0.8 mile downstream from North Pork, 2.4 miles southwest of Baloh Camp, and 8.5 

miles southeast of Trimmer.

Drainage area.--1.350 sq mi, approximately.

Records available.--December 1951 to September 1954.

Gage. Water-stage recorder. Datum of gage is 942.42 ft (revised) above mean sea level 

(levels by Corps of Engineers).

Extremes.--Maximum discharge during year, 13,400 cfs May 19 (gage height, 10.32 ft); miniraum, 134 cfs Sept. 27, 30. .

1951-54: Maximum discharge, 20,300 cfs May 30, 1952 (gage height, 12.22 ft); minimum, that of Sept. 27, 30, 1954.

Flood of Nov. 19, 1950, reached a stage of 21.6 ft, from floodmarks (levels by Corps 

of Engineers).

Remarks.--Records excellent. This station measures inflow to Pine Flat Reservoir. Plow 

slightly regulated by powerhouse on North Fork. Slight regulation by small reservoirs 

above station on Ten Mile and Mill Plat Creeks, noted in previous years, found insignificant and has no effect on flow at this station under present conditions.

296 SAN JOAQUIN RIVER BASIN 

San Joaquin River at Fremont Ford Bridge, Calif.

Location (revised). 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.

Records available.--October 1944 to September 1954 in reports of Geological Survey. Pebruary 1931? to September 1954 in reports of California Division of Water Resources.

Gage. Water-stage recorder. Prior to Dec. 8, 1949, on downstream side of Fremont Ford 

Bridge near left bank.

Average discharge.--10 years (1944-54), 662 cfs (479,300 acre-ft per year).

Extremes.--Maximum discharge during year, 2,190 cfs Feb. 17 (gage height, 65.59 ft); minimum, 39 cfs Nov. 12.

1944-54: Maximum discharge, 4,470 cfs Mar. 25, 1952; maximum gage height, 69.67 ft 

June 3, 1952; minimum discharge, 18 cfs Oct. 18, 1949.

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

from Merced River, which are poor. Natural flow of stream affected by storage reservoirs, ground-water withdrawals, diversions for irrigation, and imported water from 

Delta-Mendota Canal (see p. 347). 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. Discharge measurements generally 

made twice a month.

Cooperation.--Twelve discharge measurements furnished by California Division of Water 

Resources.

Rating tables, water year 1953-54, except period of backwater (gage

height, In feet, and discharge, in cubic feet per second)

northeast of Newman.

Drainage area. 9,990 sq mi.

Records available. April 1912 to September 1954. Prior to Oct. 1, 1937, and subsequent

 to Oct. 1, 1943, flow that bypassed station at discharges above about 9,000 cfs not included in records.

Gage.--Water-stage recorder. Datum of gage is 51.0 ft above datum of Corps of Engineers. 

"Prior to Mar. 3, 1931, staff gage at various sites within 60 ft of bridge and at same 

datum.

Average discharge.--42 years,.2,295 cfs (1,662,000 acre-ft per year).

Extremes. Maximum discharge during year, 3,500 cfs May 21 (gage height, 8.10 ft); mini-

 mum, 176 cfs Oct. 31, Nov. 12, 13; minimum gage height, 1.21 ft Oct. 31.

banK 0.5 mile downstream from Don Pedro Dam, 3.5 miles upstream from La Grange Dam, 

and 5 miles upstream from La Grange.

Drainage area. 1,540 sq mi.

Records available.--March 1915 to September 1954. August 1895 to September 1917 at La 

Grange Dam, 3.5 miles downstream, records equivalent if flow of Sierra and San Francisco Power Co.'s canal (abandoned in 1926) and Modesto and Turlock canals is added 

to flow at La Grange Dam.

£_.--Water-stage recorder. Altitude of gage is 330 ft (from topographic map). Aug. 29, 

895, to Dec. 5, 1908, staff gage on bridge pier 2 miles below La Grange Dam. Apr. 1, 

1908, to Mar. 18, 1915, staff gage on right bank 80 ft above La Grange Dam.

Average discharge.--59 years (1895-1954), 2,561 cfs (1,854,000 acre-ft per year), using 

1895-1916 records of combined flow of river and canals, and including Hetch Hetchy 

diversion to San Francisco.

Extremes. Maximum discharge during year, 7,700 cfs Mar. 11 (gage height, 13.40 ft); min- 

 imuin daily, 432 cfs Nov. 8.

1895-1954: Maximum discharge, 61,000 cfs Dec. 8, 1950 (gage height, 43.8 ft), from

rating curve extended above 9,000 cfs on basis of computation of peak flow over dam

and through powerplant; minimum daily, 2.1 cfs Dec. 27, 1922.

Remarks. Records excellent. Tuolumne Canal (see p. 329) diverts water from Stanislaus 

River basin into Tuolumne River basin for power, irrigation, and domestic supply in 

vicinity of Sonora upstream from station. Flow regulated by Don Pedro powerplant, 

Don Pedro Reservoir (see preceding page), Hetch Hetchy Reservoir (see p. 308). &nd 

Lake Eleanor (see p. 311). Diversion through Hetch Hetchy aqueduct to San Francisco 

began Oct. 19, 1934; for present year it amounted to an average of 138 cfs.

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

city and county of San Francisco.

Location. Lat 38°11', long. 120°09' , in sec. 19, T. 4 N., R. 17 E., on left bank 1 mile 

upstream from diversion dam of Pacific Gas & Electric Co. at Sand Bar Flat and 11 miles 

southeast of Avery.

Drainage area. 318 sq mi.

Records available. September 1905 to September 1954.

Gage. Water-stage recorder. Altitude of gage is 2,650 ft (from topographic map). Prior 

to Mar. 19, 1928, staff gage at diversion dam 1 mile downstream, at different datum. 

Mar. 19, 1928, to October 1938, water-stage recorder at site 150 ft downstream at present datum.

Average discharge. 48 years (1905-8, 1909-54), 700 cfs (506,800 acre-ft per year).

Extremes. Maximum discharge during year, 6,230 cfs Mar. 9 (gage height, 11.68 ft); minimum daily, 74 cfs Jan. 22.

1905-54: Maximum discharge, 26,500 cfs Dec. 11, 1937 (gage height, 21.0 ft, from 

floodmarks, at site then in use), from rating curve extended above 6,000 cfs on basis 

of velocity-area study and computation of peak flow over Sand Bar Dam; minimum daily, 

30 cfs Nov. 28, 1919, and Aug. 24, 1924.

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

Flow slightly regulated by Relief Reservoir beginning in 1909 (capacity, 15,550 acreft). Water diverted by Philadelphia Canal (see p. 328) from South Fork Stanislaus 

River through Spring Gap powerhouse into Middle Fork above station. Stanislaus tunnel 

diverts 1 mile downstream.

Cooperation.--Water-stage-recorder graph and 6 discharge measurements furnished by Pacific 

lias & Electric Co. in connection with a Federal Power Commission project.

Average discharge. 45 years (1908-23-, 1924-54), 241 cfs (174,500 acre-ft per year); median 

ol yearly mean discharges, 215 cfs (156,000 acre-ft per year).

Extremes. Maximum discharge during year, 2,060 cfs Feb. 14 (gage height, 6.65 ft); no flow 

for many days in October and September.

1907-54: Maximum discharge observed, 50,000 cfs Jan. 31, 1911 (gage height, 21.0 ft 

present datura), from rating curve extended above 11,000 cfs; no flow during late summer 

of most years.

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

Flow regulated by Hogan Reservoir at Stockton flood-control dam beginning in 1930 (usable capacity, 75,000 acre-ft), by Bingham Reservoir (capacity, 775 acre-ft) on North 

Fork Calaveras River, and by some seepage of North Fork Stanislaus River water from 

diversion canals and reservoirs; normally not over 1.5 cfs.

Revisions (water years). WSP 1011: 1907-10, 1912-28. WSP 1181: 1911.

Remarks.--Records good. Plow regulated by many reservoirs and powerplants (total usable 

reservoir capacity is about 200,000 acre-ft). Many diversions above station; diversion 

to Pit No. 5 powerhouse began May 1, 1944. For record closely comparable with previous 

record of total flow at Big Bend see Pit River below Pit No. 4 Dam, on preceding page.

Revisions. Revised figures of discharge, in cubic feet per second, for the water years 

 1911, 1917, and 1928, superseding those published in WSP 361, 461 and 671 are given

of tiowman Dam on Canyon Creek, 4 miles east of Graniteville and 8 miles south of Sierra 

City.

Drainage area. 30 sq mi, approximately.

Records available.--December 1926 to September 1954.

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

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

above mean sea level.

Extremes. Maximum contents observed during year, 70,500 acre-ft June 3 (elevation, 5,565.9 

ft]; minimum observed, 4,850 acre-ft Feb. 28 (elevation, 5,453.0 ft).

1926-54: Maximum contents observed, 70,500 acre-ft for one or more days In 1937, 

1943, 1950-51, 1953-54 (elevation, 5,565.9 ft); no contents Nov. 25 to Dec. 9, 1949.

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

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

of outlet tunnel) and 5,56.3 ft (crest of concrete-arch dam) above mean sea level. 

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

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

(see p.435), and releases it through Bowman-Spaulding Canal (see following page) which 

conveys it to reservoirs of Pacific Gas & Electric Company. Water Is eventually used 

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

are available for release.

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

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 526.99 ft above mean sea level (levels by Corps of EngiAverage discharge. 13 years, 2,646 cfs (1,916,000 acre-ft per year).

Extremes. Maximum discharge during year, 34,500 cfs Mar. 9, including flow through powerhouse; minimum daily, 153 cfs Sept. 28.

1941-54: Maximum discharge, 109,000 cfs Nov. 21, 1950, including flow through powerhouse, from rating curve extended above 25,000 efs on basis of computation of flow 

over spillway of dam of 80,000 cfs; no flow Nov. 8 to Dec. 2, 1941, Jan. 23-27, 1949, 

water being stored at dam.

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 aere-ft), Bowman Lake (see p. 434), 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.

of Knights Landing, and at mile 19.6 upstream from Sacramento.

Records available. May 1926 to September 1954 (1926-29, low-water periods only) In reports of Geological Survey. 1926-54 (1926-29, gage heights only) In reports of California Division of Water Resources.

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 same datum.

Average discharge. 25 years (1929-54), 17,650 cfs (12,780,000 acre-ft per year).

Extremes. Maximum discharge during year, 61,500 cfs Feb. 19 (gage height, 34.82 ft); mlnimum, 7,330 cfs June 23.

1926-54: Maximum discharge, 79,200 cfs Mar. 1, 1940 (gage height, 41.20 ft); minimum dally, 304 cfs Jjily 23, 24, 1931; maximum reverse flow, 16,800 cfs Dec. 4, 1950 

(backwater from American River).

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

Remarks.--Records excellent. Flow regulated by Shasta Lake beginning Dec. 30, 1943, and 

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. 477) 

Elevation of crest of Fremont weir Is 33.5 ft (datum of Corps of Engineers).

Discharge measurement made on this day
LOST RIVER BASIN 

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

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

5 miles southwest of Olene.

Records available. April 1931, when diversion began, to September 1954.

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

Average discharge. 24 years, 34.5 cfs (24,980 acre-ft per year).

Extremes. 1931-54: 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, preceding 

page.) Beginning in April 1931, water has been diverted at times from Klamath River 

and released into drain which empties into Lost River, from which it is rediverted for 

irrigation of lands near Tule Lake. Beginning in June 194$, figures of discharge 

included pumpage by Miller Hill pumping plant, which operates at times; during May 

through August 1954, pumpage amounted to 2,690 acre-ft.

Cooperation. Records furnished by Bureau of Reclamation.

Discharge, in cubic feet per second, water year October 1953 to September 1954

542 KLAMATH RIVER BASIN

Keene Creek at Hyatt Prairie, near Ashland, Oreg. _

Location. Lat 42°10', long. 122°29 I , in SW£ sec. 16, T. 39 S., R. 3 E., on right bank 

a quarter of a mile upstream from Burnt Creek, half a mile downstream from Hyatt 

Prairie Reservoir Dam, and 12 miles east of Ashland.

Drainage area. 11 sq mi, approximately.

Records 1954. available. April 1917 to June 1922 (fragmentary), November 1948 to September 

. Water-stage recorder and concrete control. Altitude of gage is 4,715 ft (by barometer). Apr. 1, 1917, to June 30, 1922, water-stage recorder at site half a mile upstream at different datum.

Average discharge. 5 years (1949-54), 13.1 cfs (9,480 acre-ft per year).

Extremes. Maximum discharge during year, 751 cfs May 3 (gage height, 5.33 ft), caused by 

failure of flashboards on spillway of Hyatt Prairie Reservoir dam, from rating curve 

extended above 50 cfs on basis of computation of peak flow over Columbus-type control; 

minimum daily, 0.1 cfs for many days.

1917-22, 1948-54: Maximum discharge, that of May 3, 1954; no flow at times.

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

Regulation since December 1922 by Hyatt Prairie Reservoir (capacity, 16,180 acre-ft). 

Practically entire flow diverted about 1 mile below station by Keene Creek Canal for 

irrigation near Ashland and Talent in Rogue River basin.

MISCELLANEOUS DISCHARGE MEASUREMENTS 555

Measurements of streamflow in the Pacific slope basins in California and Oregon made 

at points other than regular gaging 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. For many sites measurements have been made in other 

years.
