SURFACE WATER SUPPLY OF PACIFIC SLOPE BASINS IN CALIFORNIA, 1958

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, 1958. 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 14,000 gaging stations in the 48 States and at many 

others in the Territories of Alaska and Hawaii. On September 30, 1958, the Geological 

Survey and cooperating organizations were maintaining 7,090 gaging stations, including 

those in Alaska and Hawaii. 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 water year October 1, 1957, to September 30, 

1958, at gaging stations, partial-record stations, and miscellaneous sites in the Pacific 

slope basins in California are given in this report.

COOPERATION

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

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

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

Monterey County Flood Control and Water Conservation District; Orange County Flood Control 

District; Sacramento Municipal Utility District; San Bernardino Valley Water Conservation 

District; San Louis Obispo County Flood Control and Water Conservation District; Santa 

Barbara County Water Agency; Santa Cruz County Flood Control and Water Conservation 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 52 gaging stations, 

by the United States Navy for 7 gaging stations, by the Bureau of Reclamation, United 

States Department of the Interior, for 47 gaging stations, and by the Soil Conservation 

Service, United States Department of Agriculture, for 9 gaging stations. The entire 

expense of the investigation of streamflow in the Tuolumne River basin made for the Hetch 

Hetchy project and of the flow of Alameda Creek near Niles was borne by the city and 

county of San Francisco.

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

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

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

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

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

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

Turlock, Oakdale, Oroville-Wyandotte, South San Joaquin, Vista, and Woodbridge Irrigation Districts; in Oregon, The California Oregon Power Co.
2 SURFACE WATER SUPPLY, 1958, PART 11

DIVISION OF WORX

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 Califronia and Oregon were collected and prepared for publication in the district offices listed below.

State District office Address

California a/........... Menlo Park.................. 345 Middlefield Road.

Oregon b/............... Portland.................... 1001 NE. Lloyd Boulevard.

a/ Except for Fall Creek and Klamath River near Copoo.

b/ Including Fall Creek and Klamath River near Copco, Calif.

Information of a more detailed nature than that published for most of the gaging stations given in this report is on file in the district offices listed above. Some gagingstation records for California have been analyzed by electronic computer to give (1) 

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

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

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

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

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

DEFINITION OF TERMS AND ABBREVIATIONS

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

as follows:

Gaginp 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.

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 (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 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 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 aye on tributaries between any two stations on a main stem and the rank of the tributary on which each gaging station is situated.

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

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

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

from source to mouth of the uppermost tributary to the tributary.

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

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

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

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

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

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

eight digits, but the station number as 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 in the two places 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 additioa, observations of factors affecting the stage-discharge relation, 

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

54Z607 O -60 -2
4 SURFACE WATER SUPPLY, 1958, PART 11

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

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

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

methods are described in Water-Supply Paper 888 and are also outlined in standard textbooks on the measurement of stream discharge.

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

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

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

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

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

logarithmic plotting. The application of the daily mean gage height to those rating 

tables gives the daily mean discharge, from which the monthly and the yearly mean discharge are computed. If the stage-discharge relation is subject to change because of 

frequent or continual change in the physical features that form the control, the daily 

mean discharge is determined by the shifting-control method, in which correction factors 

based on individual discharge measurements and notes by engineers and observers are used 

in applying the gage heights to the rating tables. If the stage-discharge relation for a 

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

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

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

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

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

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

of an auxiliary gage set at some distance from the base gage. At some stations the stagedischarge relation is affected by changing stage. If so, the rate of change in stage is 

used as a factor in the determination of discharge.

At most gaging stations in the northern part of the United States and at some in the 

mountainous regions of'other parts the stage-discharge relation is affected by ice during 

the winter, and it becomes impossible to compute the discharge in the usual manner. Discharge for periods of ice effect is computed on the basis of the gage-height record and 

occasional winter discharge measurements, consideration being given to the available information on temperature and precipitation, notes by gage observers and engineers, and comparable records of discharge for other stations in the same or nearby basins. If the 

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

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

daily records is not changed.

The data herein presented generally comprise a description of the station, a skeleton 

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

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

on September 30. A calendar for the water year 1958 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 

daturns of previous gages used during the period of records available. Under "Average 

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

given for stations having fewer than five complete years of record or for stations where 

changes in water development during the period of record cause the figure to have little 

significance. Under "Extremes" are given the maximum discharge and gage height; the minimum discharge if there is little or no regulation; the minimum daily discharge if there 

is extensive regulation (also the minimum discharge if useful); and the minimum gage height 

(unless it is of no importance). In the first paragraph, the data given are for the complete current water year unless otherwise specified. In the second paragraph, the data 

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

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

in the third or last paragraph under "Extremes." Unless otherwise qualified, the maximum 

discharge corresponds to the crest stage obtained by use of a water-stage recorder, a 

crest-stage indicator, or a nonrecording gage read at the time of the crest. If the maximum gage height did not occur at the same time as the maximum discharge, it is given 

separately. Information pertaining to the accuracy of the records and conditions which 

affect the natural flow at the gaging station is given under "Remarks."

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

basis of data or information later obtained. Revisions of such records are usually published along with the current records in one of the annual reports. In order to make it 

easier to find such revised records, a paragraph headed "Revisions (water years)" has 

been added to the description of all stations for which revised records have been published. Listed therein are all the reports in which revisions have been published, each 

followed by the water years for which figures are revised in that report. In listing the 

water years only one number is given; for instance, 1933 stands for the water year October 1, 1932, to September 30, 1933. If no daily, monthly, or annual figures of discharge 

are concerned in the revision, that fact is brought out by notations after the year dates 

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

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

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

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

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

the drainage area necessitates corresponding revision of all figures based on the drainage area. Revised figures of cubic feet per second per square mile and runoff in inches 

resulting from a revision of the drainage area only are usually not published in the 

annual series of reports.

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

discharge for the greater part of the open-water period was determined by the shifting-
6 SURFACE WATER SUPPLY, 1958, PART 11

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

not published for stations on canals.

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

sudden or rapid fluctuation, the daily table gives the discharge corresponding to the 

daily mean gage height. For stations subject to such fluctuation the daily mean gage 

height may not indicate the true daily mean discharge, which must be obtained by averaging the discharge for parts of the day or by using the discharge integrator, an instrument for obtaining the daily mean discharge from a continuous gage-height graph and containing, as an essential element, a curve representing the stage-discharge relation at the 

station. For stations equipped with nonrecording gages, the table of daily discharge 

gives the discharge corresponding to once-daily readings of the gage, or to the mean of 

twice-daily readings, or to the mean gage height determined from gage-height graphs based 

on gage readings. For periods of rapidly changing stage, the daily mean discharge is 

determined from gage-height graphs based on gage readings, the frequency of which is 

stated in the station description.

In the table of daily discharge, the figures for the maximum day and the minimum day 

for each month are underlined. If the figure is repeated, it is underlined only on the 

first day of its occurrence.

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

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

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

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

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

second per square mile and runoff in inches are omitted if the drainage area includes 

large noncontributing areas, or if the average annual rainfall over the drainage basin is 

usually less than 20 inches.

In the yearly summary below the monthly summary, the figures of maximum are the maximum daily discharges, not the momentary discharges when the water was at crest stage. 

Likewise, the minimums in this summary are the minimum daily discharge.

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

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

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

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

which the peaks are subject to substantial control by man.

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

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

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

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

they were made at frequent regular intervals, in which instance the general frequency of 

discharge measurements is given under "Remarks" in the station description.

For most gaging stations on lakes and reservoirs the data presented comprise a 

description of the station and a monthly summary table of stage and contents. For some 

reservoirs a table showing daily contents or stage is given. A skeleton table of
ACCURACY OF FIELD DATA AND COMPUTED RESULTS 7

capacity at given stages is usually given in the first report in which data for the reservoir are published, but it is omitted from succeeding reports.

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

making chemical analyses, computing dissolved 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 

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.
SURFACE WATER SUPPLY, 1958, PART 11

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

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

because water must first be supplied to existing irrigation systems.

PUBLICATIONS

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 1.

HYDROLOGIC CONDITIONS

Runoff was generally above median in Oregon throughout the water year except in March 

and May, when it was below median. Runoff was generally above median or excessive throughout the water year in most of California except for October to January and July to September, when it was below median in the extreme southern part. Santa Ana River near Mentone, 

Calif., was record low for October. Throughout northern and central California runoff 

was excessive as a. result of the wettest winter in 68 years. Coastal areas for these 

parts of the State experienced runoff during the water year that in general averaged 

about 225 percent of median, while in the Central Valley runoff during the water year was 

about 160 percent of median. A succession of major storms during the 2-|-month period 

from late January to early April caused streams to reach or exceed bankful stages on several occasions. Floods occurred in late February in the Sacramento River basin causing 

damage to low-lying areas that was estimated at several million dollars. Flood peaks 

were of record-breaking proportions in the Stony and Cache Creek basins. An even more
HYDROLOGIC CONDITIONS 15

severe flood occurred in central California in early April. The unusual features of this 

flood were its occurrence so late in the season and its being centered so much farther 

south than usual. Numerous streams reached their highest levels of record and the President of the United States declared the State a major disaster area. For three key gaging 

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

discharge during the 1958 water year with the median discharge for the 25-year period 

1921-45 is shown in figure 2 on the following page. For Kings River at Piedro, Calif., 

the discharges shown have been adjusted for storage.

outlet tower.

Drainage area. 120 sq mi, approximately.

Records available . January 1916, October 1936 to September 1958.

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

Average discharge.--22 years (1936-58), 13.9 cfs (10,060 acre-ft per year); median of 

yearly mean discharges , 7.3 cfs (5,300 acre-ft per year).

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

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

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

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

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

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

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

required.

Drainage area. 98 sq mi, approximately.

Records available. October 1936 to September 1958.

Gage.--Staff gage read once daily. Datum of gage is 347.20 ft above mean sea level. 

~;S"ince Oct. 1, 1945, auxiliary staff gage read two or more times per week near Upper 

Otay Dam. Datum of gage is 477.50 ft above mean sea level.

Remarks.--Records of inflow represent all water reaching Upper and Lower Otay Reservoirs, 

Including precipitation on the reservoir surfaces and water brought in by Dulzura 

conduit, computed on basis of records of storage, release (draft), spill, leakage, and 

evaporation. Area and capacity tables for Upper Otay Reservoir are dated Mar. 23, 

1955; for Lower Otay Reservoir, Apr. 3, 1956, and May 25, 1956. Monthly evaporation 

from lake surface computed on basis of evaporation from Colorado pan using coefficient 

of 0.80. Capacity of upper reservoir at spillway level (gage height, 72.02 ft), 

2,825 acre-ft; capacity of lower reservoir at permanent spillway level (gage height, 

137.50 ft), 49,511 acre-ft. Dead storage of upper reservoir, 438 acre-ft below lowest 

outlet at gage height 43.32 ft; of lower reservoir, 1,154 acre-ft below lowest outlet 

at gage height 47.85 ft, included in these records. Dulzura conduit (see p. 19)* 

carries water from Barrett Reservoir on Cottonwood Creek (see p. 18) to Dulzura Creek, 

whence the water is carried to Lower Otay Reservoir by Jamul Creek (see p. 24). Small 

diversions for local use near reservoir. Water from these reservoirs is used for 

municipal supply by the city of San Diego.

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

Note .--For months when inflow to 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.
26 SWEETWATER RIVER BASIN

150. Sweetwater River near Descanso, Calif.

Location. Lat 32°50'05", long 116°37'20", in NWpSEi sec.25, T.15 S., R.3 E., on right

records of river and diversion, October 1956 to September 1958.

Gage.--Water-stage recorder. Datum of gage is 3,269.24 ft above mean sea level, datum 

of 1929. November 1905 to June 25, 1927, staff gages at several sites within 0.1 mile 

upstream at various datums.

Average discharge. 24 years, 14.9 cfs (10,790 acre-ft per year), unadjusted; median of 

yearly mean discharges, 8.4 cfs (6,100 acre-ft per year).

Extremes. Maximum discharge during year, 1,290 cfs Apr. 3 (gage height, 6.60 ft), from 

rating curve extended above 530 cfs by logarithmic plotting; no flow many days. 

1905-27, 1956-58: Maximum discharge, 11,200 cfs Feb. 16, 1927 (gage height, 

13.2 ft, from floodmark, site and datum then in use), on basis of slope-area measurement of peak flow; no flow many days in some years.

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

made twice a month. Sweetwater River diversion ditch diverts about 0.3 mile above 

station for irrigation below station. For records of combined discharge of river and 

diversion see following page.

32 SAN DIEGO RIVER BASIN

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 ml.

Records available.--May 1912 to September 1958 (incomplete prior to 1920). 

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

T80 ft (from topographic map). Prior to Nov. 10, 1920, staff gage at site 1^ 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. 43 years (1912-15, 1917-18, 1919-58), 27.8 cfs (20,130 acre-ft per

year); median of yearly mean discharges, 5.0 cfs (3,600 acre-ft per year). 

Extremes. Maximum discharge during year, 2,750 cfs Apr. 3 (gage height, 5.85 ft), from

rating curve extended above 570 cfs on basis of slope-area measurement of peak flow;

no flow many days.

1912-58: 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 most years. 

Revisions. Figures of maximum discharge for the water years 1955-56 have been

revised to 90 cfs Jan. 19, 1955 (gage height, 2.29 ft), and 62 cfs Apr. 14, 1956 (

height, 2.17 ft), superseding those published in WSP 1395 and 1445, respectively. 

Remarks.--Records good. 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 Cuyamaca, El Capitan (see p. 30, 31 ), and San Vicente Reservoirs.

Diversions above station by city of San Diego for municipal supply and by Helix

Irrigation District. 

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

in the water years 1955-56, superseding those published in WSP 1395 and 1445, are

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

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

of Ramona.

Drainage area.--57 sq mi, approximately.

Records available. December 1912 to September 1928, October 1936 to September 1958. 

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 

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

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

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

and datum.

Average discharge.--37 years (1913-28, 1936-58), 20.9 cfs (15,150 acre-ft per year); 

median of yearly mean discharges, 12 cfs (8,700 acre-ft per year).

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

precipitation on reservoir, 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.

t Gage height at 12 p.m. on last day of month.

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

negative or discordant figures of runoff may appear. This arises primarily from the 

difficulty of computing runoff as a 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.

Records available.--December 1946 to September 1958.

Gage. Water-stage recorder and concrete control. Altitude of gage is 560 ft (from topographic map).

Average discharge.--11 years (1947-58), 1.37 cfs (992 acre-ft per year); median of yearly 

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

Extremes.--Maximum discharge during year, 1,660 cfs Apr. 3 (gage height, 5.83 ft), from 

rating curve extended above 440 cfs on basis of slope-area measurement of peak flow; no 

flow many days.

1946-58: Maximum discharge, that of Apr. 3, 1958; no flow at times most years.

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

30 cfs, which are fair. Discharge measurements generally made twice monthly. Diversion about a quarter of a mile upstream for irrigation.

SAN DIEGUITO RIVER BASIN 39

300. San Dieguito River at Lake Hodges, Calif.

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

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

Drainage area. 303 sq mi.

Records available. January 1916 to September 1958. Published as "near Bernardo" prior 

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

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

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

dam).

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

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

aqueduct of San Diego County Water Authority; 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. Monthly evaporation from lake surface computed on 

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

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

below lowest outlet at gage height 54.0 ft, included in these records. Diversions for 

irrigation above Lake Hodges. Water drawn from Lake Hodges passes through a conduit 

to San Dieguito reregulatlng reservoir, from which it is released as required for 

municipal use. Flow regulated since July 1954 by Sutherland Reservoir (see p. 33).

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

Revisions (water years). WSP 1091: 1946. WSP 1121: 1947.

SAN LUIS KEY RIVER BASIN 41

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

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

4 miles north of Mesa Grande, San Diego County.

Drainage area. 209 sq mi.

Records available.--January 1923 to September 1958. October 1911 to January 1923 at site 

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

in natural water losses resulting from creation of Lake Henshaw.

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

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

January 1923, water-stage recorder at site 1 mile downstream at different datum.

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

site; 36 years (1922-58), 29.7 cfs (21,500 acre-ft per year), discharge at Lake Henshaw, exclusive of 90 percent of precipitation on lake surface; median of yearly mean 

discharges, 18 cfs (13,000 acre-ft per year).

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

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

pumping ground water from lake bed, computed on basis of records of storage, release 

(draft), spill, leakage, evaporation, precipitation, and ground-water pumpage. 

Monthly evaporation from lake surface computed on basis of evaporation from a floating 

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

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

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

in October 1951. Capacity of lake at spillway level (gage height, 107.00 ft), 

194,300 acre-ft. No dead storage. Since storage of water was begun, runoff as computed has been exclusive of 90 percent of rainfall on water surface of lake. During 

the year the amount of precipitation excluded was 2,878 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. Records furnished by Vista Irrigation District.

Drainage area. 319 sq mi.

Records available. October 1948 to September 1958. January 1923 to October 1930 at site 

200 ft downstream and October 1930 to September 1948 at site 500 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. October 1951 to September 1955, published as "at Vail dam, near 

Temecula."

Gage. Water-stage recorder. 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. Prior to Oct. 16, 1930, at site 200 ft downstream at several different daturas. Oct. 16, 1930, to September 1948 at site 500 ft downstream at different 

datum.

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

(1948-58), 5.82 cfs (4,210 acre-ft per year); median of yearly mean discharges, 2.8 cfs 

(2,000 acre-ft per year).

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. Monthly evaporation from lake surface computed on basis of evaporation 

from Class A pan using coefficient of 0.80. Capacity and area ratines 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. Record of lake water-surface elevations furnished by Santa Margarita Ranch 

(U. S. Navy) and Pauba Ranch.

Feb. 2, 1931, to Nov. 27, 1935, at same site at datum 1.00 ft higher.

Average discharge. 34 years, 34.2 cfs (24,760 acre-ft per year).

Extremes. Maximum discharge during year, 5,000 cfs Apr. 2 (gage height, 12.78 ft) from 

rating curve extended above 800 cfs by logarithmic plotting; no flow Oct. 1 to Mar 15 

June 2 to Sept. 30. '

1923-29, 1930-58: Maximum discharge, 33,600 cfs Feb. 16, 1927, on basis of slopearea measurement of peak flow; no flow part of most years.

Remarks.--Records poor. Diversions above station for irrigation on Santa Margarita Ranch 

and Pauba Ranch. (See preceding page for records of O'Neill di^ch near Ysidora.) Flow 

partly regulated by Vail Reservoir (see p. 45) beginning in November 1948. "Average 

discharge represents flow to ocean during period of record, regardless of upstream 

development.

Cooperation. Gage-height record, 18 discharge measurements, and almost daily observation 

of no flow furnished by Santa Margarita Ranch (U. S. Navy) and Pauba Ranch.

Location. Lat 34°11'05", long 117°32'20", in NW^NWiSW^ sec. 8, T.I N. , R.6 W. , on left 

bank 0.5 mile downstream from confluence of 2 main forks and 4 miles north of Etiwanda.

Records available.--January 1929 to September 1958. Combined creek and diversion, October 

1950 to September 1958.

Gage. Water-stage recorder and broad-crested weir. Altitude of gage is 2,870 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. 29 years, 3.92 cfs (2,840 acre-ft per year); median of yearly mean 

discharges, 2.8 cfs (2,000 acre-ft per year). Average combined discharge of Day Creek 

and diversion, 8 years (1950-58), 3.56 cfs (2,580 acre-ft per year).

Extremes. Maximum discharge during year, 355 cfs Dec. 15 (gage height, 3.35 ft); minimum 

daily, 0.2 cfs many days.

1929-58: 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 100 cfs and fair above. 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 the gravel in the bed of the stream at the gaging station, 

produced 710 acre-ft during year.

92 SANTA ANA RIVER BASIN

740. Santa Ana River below Prado Dam, Calif.

Location.--Lat 33°53'00", long 117°38 T 40", in La Sierra Grant, on left bank of outlet 

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

Riverside County.

Drainage area . 1,462 sq mi.

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

September 1958. Published as "at Santa Pe Railroad Bridge, near Prado" May 1930 to 

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

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

above mean sea level (Corps of Engineers survey). Prior to Mar. 18, 1940, waterstage recorder at about same site at various dat urns.

Extremes. Maximum discharge during year, 842 cfs Apr. 4 (gage height, 4.09 ft); minimum 

daily, 26 cfs Aug. 7.

1940-58: Maximum discharge, 2,260 cfs Dec. 24, 1940 (gage height, 3.20 ft); minimum daily, 20 cfs July 29, 31, Aug. 1, Sept. 6, 1957.

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

regulated by Prado Reservoir (capacity, 222,800 acre-ft) and Big Bear Lake (see p. 56). 

There was no Colorado River water released to the Santa Ana River during water year 

1957-58. Natural flow of stream affected by extensive ground-water withdrawals, 

diversion for irrigation, and return flow from irrigated areas. Santa Ana River 

Development Co. pumps water from wells above Prado Reservoir into a conduit which 

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

Cooperation. Twenty-five discharge measurements and records of bypass flow were furnished by Orange County Flood Control District.

Rating table, water year 1957-58 (gage height, in feet, and discharge,

in cubic feet per second)

(Shifting-control method used Oct. 1 to Feb. 3, Feb. 12 to Mar. 7, 

Mar. 13-16, Mar. 19 to Apr. l)

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

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

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

Extremes. Maximum discharge during year, 1,200 cfs Apr. 3 (gage height, 7.42 ft); minimum daily, 29 cfs (estimated) Aug. 8.

1919-40, 1952-58: Maximum discharge, 100,000 cfs (estimated) Mar. 3, 1938 (gage 

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

daily, 24 cfs July 31, 1957.

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

regulated by Prado Reservoir (capacity, 222,800 acre-ft) and Big Bear Lake (see p. 56). 

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

return flow from irrigated areas.

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

District.

Gage. Water-stage recorder. Altitude of gage is 8( 

TT923, to Jan. 24, 1929, at datum 1.00 ft higher, 

site 450 ft upstream at different datum.

Average discharge . 18 years (1940-58), 16.7 cfs (12,090 acre-ft per year); median of 

yearly mean discharges, 2.3 cfs (1,700 acre-ft per year).

Extremes. Maximum discharge during year, about 9,000 cfs Apr. 3, caused by failure of 

temporary dam 4 miles upstream; no flow many days.

1923-58: Maximum discharge, 46,300 cfs Mar. 3, 1938 (gage height, 10.20 ft, former 

site and datum), on basis of slope-area measurement of peak flow; no flow several 

months each year.

Remarks. Records fair. Natural flow affected by ground-water withdrawals, diversions, 

importation from Metropolitan Water District, municipal use, return flow from irrigation, and several storage reservoirs, including Prado flood-control reservoir 

(capacity, 222,800 acre-ft), and Big Bear Lake (see p. 56). At times there are small 

amounts of return irrigation water from Santa Ana Valley Irrigation Co.'s drain 

1,500 ft upstream.

100 SAN GABRIEL RIVER BASIN

835. San Gabriel River near Azusa, Calif.

Location. Lat 34°10'11", long 117°53'16", in SW^NW^-SW-jj 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.--May 1894 to September 1958.

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

Tngeles 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 l|-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. 63 years (1895-1958), 154 cfs (111,500 acre-ft per year), adjusted 

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

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

(78,900 acre-ft per year).

Extremes.--Maximum discharge during year, 2,780 cfs Apr. 5 (gage height, 9.22 ft); no 

flow Oct. 1 to Feb. 4, Aug. 25 to Sept. 30.

1894-1958: Maximum discharge, 65,700 cfs Mar. 2, 1938, by computation of peak 

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

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

two or more times 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 discharge of 92 acre-ft of Colorado River 

water into San Gabriel River below Morris Dam and above station during the 1958 water 

year. They also furnished records of adjusted runoff for San Gabriel River computed 

on basis of flow in river above Morris Reservoir plus Azusa Canal, adjusted for 

storage and evaporation in Cogswell, San Gabriel, and Morris Reservoirs, as shown in 

table below. These figures of runoff are equivalent to combined records of San 

Gabriel River and Southern California Edison Co.'s canal as published from 1894 to 

1933.

960. Haines Creek near Tu junga , Calif.

Location. Lat 34°15'50", long 118°16'15", in NW^NWir sec. 17, T.2 N., R.13 W., on right bank

 0.5 mile upstream from mouth of canyon and 1.5 miles northeast of Tu junga .

Drainage area.--1.2 sq mi, approximately.

Records available .--Creek: February 1917 to September 1934, October 1935 to September

1958. Diversion: January 1931 to September 1958. 

Gage. --Water-stage recorder and broad-crested weir. Altitude of gage is 2,430 ft (from

Topographic map) . 

Average discharge .--40 years, 0.14 cfs (101 acre-ft per year); median of yearly mean dis-

 charges, 0.1 cfs (70 acre-ft per year). Average combined discharge of creek and 

diversion, 26 years (1931-34, 1935-58), 0.38 cfs (275 acre-ft per year); median of 

combined yearly mean discharges, 0.2 cfs (140 acre-ft per year).

Extremes. --Maximum discharge during year, 20 cfs Apr. 3 (gage height, 2.56 ft); no flow 

most days .

1917-34, 1935-58: Maximum discharge, 265 cfs Mar. 2, 1938 (gage height, 4.6 ft), 

from rating curve extended above 3.2 cfs on basis of velocity-area studies; maximum 

gage height, about 11 ft Jan. 1, 1934 (caused by debris wave commonly called a mud 

flow); no flow at times many years.

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

3 cfs , which are poor. Discharge measurements or observations of no flow generally 

made twice a month. City of Los Angeles diverts most of flow through two infiltration 

galleries upstream from station.

Cooperation. Records of diversion furnished by city of Los Angeles.

VENTURA RIVER BASIN 

1185. Ventura River near Ventura, Calif.

161

Location.--Lat 34°21'05", long 119°18 I 23", in southeast corner of Santa Ana Grant, on 

right bank 500 ft downstream from county highway bridge at Foster Memorial Park, 

0.2 mile downstream from Coyote Creek, and 5 miles north of Ventura, Ventura County.

Drainage area. 187 sq mi.

Records available. September 1911 to January 1914, October 1929 to September 1958.

Gage. Water-stage recorder. Altitude of gage is 200 ft (from topographic map). Prior 

To Jan. 18, 1914, chain gage at site 370 ft upstream at different datum (destroyed by 

flood). October 1929 to Nov. 2, 1949, at site 370 ft upstream at present datum.

Average discharge. 31 years (1911-13, 1929-58), 63.2 cfs (45,830 acre-ft per year); 

median of yearly mean discharges, 28 cfs (20,300 acre-ft per year). Average combined 

discharge of river and diversion, 25 years (1933-57), 77.4 cfs (56,040 acre-ft per 

year); median of combined yearly mean discharges, 34 cfs (24,600 acre-ft per year).

Extremes.--Maximum discharge during year, 18,700 cfs Apr. 3 (gage height, 17.25 ft), from 

rating curve extended above 8,000 cfs on basis of slope-area measurement of peak flow; 

no flow Oct. 1 to Dec. 15.

1911-14, 1929-58: Maximum discharge, 39,200 cfs Mar. 2, 1938 (gage height, 

19.2 ft), from rating curve extended above 7,700 cfs on basis of slope-area and 

contracted-opening measurements of peak flow; no flow at times many years.

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

Discharge measurements or observations of no flow generally made twice a month. Flow 

partly regulated by Matilija Reservoir since Mar. 14, 1948 (see p. 156 ). Water 

diverted through pipeline at dam to Ojai Valley for irrigation since May 1951 (see 

p. 156 ). City of Ventura diverts water above station for municipal supply. For 

records of combined discharge of river and diversion, see following page.

Cooperation. Three discharge measurements furnished by Ventura County Water Resources 

Diversion. Gage-height record for diversion weir furnished by city of Ventura.

Revisions Revised figures of combined discharge for the water year 1957, superseding 

those published in WSP 1515, are given herein.

discharges, 0.4 cfs [290 acre-ft per year).

Extremes.--Maximum discharge during year, 1,980 cfs Apr. 3 (gage height, 6.59 ft), from 

rating curve extended above 800 cfs as explained below; no flow many days.

1941-58: 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 each year.

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

more times 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.

Note. No gage-height record Sept. 24-3O; discharge estimated on basis of recorded range in stage.
166 SANTA YNEZ RIVER BASIN

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

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

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

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

Records available.--December 1930 to September 1958. Prior to October 1938, published as 

"at Juncal Reservoir, near Montecito."

Gage. 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.--27 years (1931-58), 6.12 cfs (4,430 acre-ft per year); median of 

yearly mean discharges, 2.3 cfs (1,700 acre-ft per year).

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

precipitation on lake, computed on basis of records of storage, diversion to the city 

of Montecito (draft), 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 (corrected). 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 the 

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.

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, computed on basis of records of storage, diversion to city of Santa Barbara (draft), spill and release to river, and evaporation. 

Records of net inflow exclude precipitation on water surface, computed on basis of 

area and records of precipitation. Monthly evaporation from reservoir surface computed on basis of evaporation from Class A pan using coefficient of 0.80. Reservoir 

capacity and area tables are based on surveys made in 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).

Mote. For months when inflow to the reservoir was small and other quantities were large, discordant figures of net inflow 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.
168 SANTA YNEZ RIVER BASIN

1230. Santa Ynez River below Gibraltar Dam, near Santa Barbara, Calif.

Location. Lat 34°31'28", long 119°41'11", in southwest portion of Los Padres National 

Forest, on left bank 700 ft downstream from Gibraltar Dam and 7 miles north of Santa 

Barbara, Santa Barbara County.

Drainage area. 216 sq mi.

Records available. April 1920 to September 1958 (monthly discharge only prior to October 

1941).

Gage. Water-stage recorder. Altitude of gage is 1,250 ft (from topographic map). Waterstage recorder and sharp-crested weir on outlet channel below dam and water-stage 

recorder on Gibraltar Reservoir used as supplementary gages. Prior to Apr. 17, 1952, 

water-stage recorder on Gibraltar Reservoir used as principal gage. Apr. 17 to 

Oct. 15, 1952, staff gage and Oct. 16, 1952, to May 20, 1958, water-stage recorder at 

same site at datum 5.00 ft higher.

Average discharge. 38 years, 38.3 cfs (27,730 acre-ft per year), unadjusted; median of 

yearly mean discharges, 11 cfs (8,000 acre-ft per year).

Extremes.--Maximum discharge during year, 17,400 cfs Apr. 3 (gage height, 14.37 ft); no 

flow Jan. 1-24.

1920-58: Maximum discharge, 35,500 cfs Mar. 2, 1938, computed from spillway rating; 

no flow at times most years.

Remarks. Records good below 500 cfs and fair above. Discharge represents flow in Santa 

Ynez River passing Gibraltar Dam. Plow regulated by Gibraltar Reservoir and Jameson 

Lake (see p. 167, 166). City of Santa Barbara diverted 5,170 acre-ft during the water 

year from Gibraltar Reservoir; Montecito County Water District diverted 909 acre-ft 

during the water year from Jameson Lake.

SANTA YNEZ RIVER BASIN 169

1235. Santa Ynez River below Los Laureles Canyon, near Santa Ynez, Calif.

Location. Lat 34°32'35", long 119°51'45", in San Marcos Grant, on left bank 0.1 mile 

downstream from Los Laureles Canyon Creek and 13 miles east of Santa Ynez, Santa Barbara County.

Drainage area. 277 sq mi.

Records available.--April 1947 to September 1958.

Gage. Water-stage recorder. Datum of gage is 794.52 ft above mean sea level, datum of 

T929 (Bureau of Reclamation bench mark).

Average discharge. 11 years, 40.6 cfs (29,390 acre-ft per year); median of yearly mean 

discharges, 2.6 cfs (1.900 acre-ft per year).

Extremes.--Maximum discharge during year, 15,000 cfs Apr. 3 (gage height, 12.25 ft); no 

flow many days.

1947-58: Maximum discharge, 33,000 cfs Jan. 15, 1952 (gage height, 15.6 ft), from 

rating curve extended above 6,400 cfs on basis of slope-area measurement of peak flow 

at station below Gibraltar Dam; no flow several months each year.

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

Discharge measurements or observations of no flow generally made twice a month. Flow 

regulated by Jameson Lake and Gibraltar Reservoir (see p. 166, 167). Water diverted 

out of basin from these reservoirs to cities of Montecito and Santa Barbara for municipal supply. Flow affected by intermittent local pumping for irrigation above station 

and from infiltration gallery in river bed at station.

Discharge, In cubic feet per second, water year October 1957 to September 1958

1385. Slsquoc River near Slsquoc, Calif.

Location. Lat 34°50'25", long 120°10'00", in sec.20, T.9 N., R.31 W., on left bank 

2.2 miles upstream from La Brea Creek and 7 miles east of Sisquoc.

Drainage area. 290 sq mi.

Records available. October 1943 to September 1958. December 1929 to September 1933 at 

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

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

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

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

flow.

Average discharge. 15 years (1943-58), 31.1 cfs (22,520 acre-ft per year); median of 

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

Extremes. Maximum discharge during year, 7,640 cfs Apr. 3 (gage height, 10.62 ft), from 

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

10.08 ft; minimum daily, 0.6 cfs Oct. 28-31.

1930-33, 1943-58: Maximum discharge, that of Apr. 3, 1958; minimum daily since 

1943, 0.4 cfs Sept. 14, 19, 21, 1947, Oct. 5-9, 20-22, Nov. 18, 1951, and Nov. 2-11, 

1957.

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

2,800 cfs by logarithmic plotting.

Remarks.--Records good. Discharge measurements generally made twice a month.

1525. Salinas River near Spreckels, Calif.

Location. Lat 36°37'50", long 121°40'40", in El Toro Grant, on right bank 80 ft upstream 

from bridge on Salinas-Monterey highway, 0.5 mile upstream from Toro Creek, 2 miles 

west of Spreckels, Monterey County, and 4 miles south of Salinas.

Drainage area. 4,231 sq mi.

Records available. January 1900 to August 1901, December 1929 to September 1958. Published as "near Salinas" 1900-1901.

Gage. Water-stage recorder. Datum of gage is 22.64 ft above mean sea level, adjustment 

of 1912. 1900-1901, May 10 to July 29, 1940, staff gage at same site at different 

datum. Since Mar. 17, 1941, supplementary wire-weight gage on highway bridge 80 ft 

downstream at same datum.

Average discharge. 28 years (1930-58), 480 cfs (347,500 acre-ft per year); median of 

yearly mean discharges, 250 cfs (181,000 acre-ft per year).

Extremes. Maximum discharge during year, 35,600 cfs Apr. 4 (gage height, 23.15 ft); minimum not determined.

1929-58; 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 figures of maximum discharge for some water years have been revised, 

as shown in the following table. They supersede those published in the water-supply 

papers indicated.

1905. Isabella Reservoir near Isabella, Calif.

Location. Lat 35°38'50", long 118°28'50", in SW£ see.19, T.26 S., R.33 E., in main 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. 2,093 sq mi.

Records available. October 1953 to September 1958.

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

Engineers).

Extremes.--Maximum contents during year, 455,200 acre-ft June 28 (elevation,2,594.83 ft); 

minimum, 100,900 acre-ft Jan. 22, 23 (elevation, 2,546.08 ft).

1953-58: Maximum contents, that of June 28, 1958; minimum since appreciable storage 

was attained, 4,330 acre-ft Apr. 21, 1955.

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. 569,700 acre-ft 

between elevations 2,470.0 (invert of main outlet) and 2,605.5 ft (spillway crest) above 

mean sea level. Dead storage, 326 acre-ft is not available for release. Surcharge 

flood control storage, 271,800 acre-ft between ungated spillway crest and elevation 

2,627.0 ft (maximum design spillway flood pool). Figures, including extremes, given 

herein represent total contents. Water is released to Kern River through tunnel in 

left abutment of main dam and to Borel Canal through concrete conduit in auxiliary dam.

Cooperation. Record of contents furnished by Corps of Engineers and reviewed by Geologleal Survey.

1925. Kern River near Democrat Springs, Calif.

Location. Lat 35°31'20", long 118°40'40", in NE^SE-p sec.6, T.28 S., R.31 E., on left 

frank 1.0 mile southwest of Democrat Springs and 2.1 miles upstream from Cow Creek.

Drainage area. 2,264 sq mi.

Records available.--July 1950 to September 1958. Prior to October 1954, records for Kern 

River and Kern River No. 1 conduit published separately.

Gage.--Water-stage recorder. Altitude of gage is 1,850 ft (from topographic map).

Average discharge.--8 years, 988 cfs (715,300 acre-ft per year), adjusted for storage 

combined flow of Kern River and Kern River No. 1 conduit. Figures published in 

WSP 1395 and 1515 were not adjusted for storage. Adjusted figures are as follows: 

7 years, 924 cfs (668,900 acre-ft per year); 6 years, 984 cfs (712,400 acre-ft per 

year); 5 years, 945 cfs (684,200 acre-ft per year).

Extremes (river only) . Maximum discharge, 3,960 cfs June 12 (gage height, 13.68 ft); minimum daily, 1.3 cfs Jan. 19-23.

1950-58: Maximum discharge, 40,000 cfs Nov. 19, 1950 (gage height, 30.7 ft), from 

rating curve extended above 8,700 cfs on basis of computation of peak flow over dam 

(basic data for computation furnished by Southern California Edison Co.); minimum 

daily, 0.1 cfs Oct. 30 to Nov. 12, 1955.

Remarks.--Records fair. Records of daily discharge presented herein include flow of Kern 

River No. 1 conduit which diverts from left bank of Kern River in sec.13, T.28 S., 

R.30 E., for power development; water is returned to river 7 miles below station. 

Flow regulated by Isabella Reservoir beginning in 1954 (see p. 264). Many diversions 

above station for irrigation.

Cooperation. Vater-stage-recorder graph and 12 discharge measurements for river and 

water-stage-recorder graph and 14 discharge measurements for conduit furnished by

268 TULARE LAKE BASIN

1970. Tulare Lake in Kings County, Calif.

Location. Lat 36°03'10", long 119°49'35", on inside of levee at "Navy White House" 

2.2 miles southwest of Chatom Ranch and 9.5 miles south of Stratford.

Records available.--March 1906 to September 1920 (incomplete), February 1937 to September 1958.

Gage. Staff gage. Datum of gage is at mean sea level. March 1906 to September 1920 

staff gages at various sites at different datums. February 1937 to September 1958 

water-stage recorder or staff gage at various sites.

Extremes.--1906-58: Maximum elevation, 196.8 ft June 27, 28, 1941; lake dry or practically so during parts of 1906, 1914-16, 1919, 1937, 1946, 1950-53, 1955-56, 1958; lake 

dry during entire years 1920-22, 1924-36, 1947-49, 1954, 1957. Lake elevation of 

June 27, 28, 1941, was highest known since about 1890.

Remarks. During 1958 inundated area of Tulare Lake basin was confined by levee systems to 

an area of 34 sections or approximately 21,760 acres. In addition to Tulare Lake basin 

area the Progressive District, comprising of approximately 2,100 acres, was flooded and 

was still flooded in August 1958 to an average depth of approximately 3 ft. It was 

pumped dry in September. Tulare Lake receives water from Kings, Kaweah, and Tule 

Rivers during high-water periods and occasionally from Kern River, Deer Creek, and 

several small intermittent streams. Its natural boundary has been greatly altered by 

construction of levees and other reclamation work. Elevation at lowest point of lake 

bed is now about 180 ft above mean sea level.

Cooperation. Record furnished by Tulare Lake basin Water Storage District.

just downstream from spillway of Florence Lake Dam and 6 miles upstream from Bear Creek.

Drainage area. 171 sq ml.

Records available. December 1921 to September 1958.

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

7,200 ft (from topographic map).

Average discharge.--35 years (1922-31, 1932-58), 307 cfs (222,300 acre-ft per year), 

combined flow of South Fork San Joaquin River and Ward tunnel at intake.

Extremes. Maximum discharge during year, 2,710 cfs June 18 (gage height, 14.34 ft); 

minimum daily, 2.1 cfs Mar. 11, 12.

1921-58: Maximum discharge, 4,320 cfs June 6, 1940 (gage height, 15.38 ft); no 

flow at times.

Remarks. Records excellent except those for periods of ice effect, which are good.

Flow regulated by Florence Lake beginning in 1925 (see preceding page) and by diversion 

into Ward tunnel (see p. 304).

Cooperation.--water-stage-recorder graph and seven discharge measurements furnished by 

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

2615. San Joaquln 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.--October 1944 to September 1958 in reports of Geological Survey. February 1937 to September 1958 in reports of California Department of Water Resources.

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

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

Average discharge.--14 years (1944-58), 679 ofs (491,600 acre-ft per year).

Extremes. Maximum discharge during year, 5,910 ofs Apr. 6 (gage height 71 14 ft)- minimum, 33 cfs Nov. 20.

1944-58: Maximum discharge, that of Apr. 6, 1958; minimum, 18 cfs Oct. 18, 1949.

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. 399). 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 and water temperatures 

for the water year 1958 are given in WSP 1574.

2755. Hetch Hetchy Reservoir at Hetch Hetchy, Calif.

Location.--Lat 37°57', long 119°47', in Nw£ sec.16, T.I N., R.20 E., near center of

O'Shaughnessy Dam on Tuolumne River at Hetch Hetchy in Yosemite National Park, 1.5 miles 

downstream from Falls Creek.

Drainage area. 460 sq mi.

Records available.--May 1923 to September 1930 (daily gage heights; also summary of yearly 

contents in WSP 881), October 1930 to September 1958.

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

county of San Francisco). Prior to Oct. 1, 1927, staff gage at same site and datum.

Extremes.--Maximum contents during year. 361,700 acre-ft July 23 (elevation, 3,806.7 ft); 

minimum, 90,300 acre-ft Apr. 26, 27 (elevation, 3,633.6 ft).

1923-58: Maximum contents, 369,100 acre-ft Dec. 3, 1950 (elevation, 3,810.4 ft); 

no contents at times in 1929-31.

Remarks. Reservoir is formed by concrete gravity-type dam, completed to crest elevation 

 577^6.5 ft in 1923 and raised to 3,812.0 ft in 1937; storage began Apr. 6, 1923. Tenfoot drum gates were installed on spillway in 1949. Usable capacity, 360.400 acre-ft 

between elevations 3,512.0 (somewhat above bottom outlet) and 3,806.0 ft (top of drumtype spillway gates) above mean sea level. Water flows down Tuolumne River 15 miles 

to Early intake, where part is diverted through Hetchy Hetchy aqueduct to Mocassin 

Creek powerplant. At Moccasin Creek diversion dam, water re-enters Hetchy Hetchy 

aqueduct and flows into Crystal Springs Reservoirs, which supplies city of San Francisco. Surplus water is spilled into Don Pedro Reservoirs at Red Mountain Bar. Hetch 

Hetchy Reservoir is main storage unit of Hetch Hetchy water-supply system for San 

Francisco.

Extremes.--Maximum discharge during year, 13,400 cfs Apr. 3 (gage height, 13.94 ft); 

minimum dally, 10 cfs Dec. 11-13.

1931-58: Maximum discharge, 62,800 cfs Dec. 23, 1955 (gage height, 29.0 ft; from 

floodmarks) , from rating curve extended above 14,000 cfs on basis of computed flow 

over Melones Dam; minimum dally, 0.4 cfs Jan. 19, 20, 1943.

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

from Tullock Reservoir, which are fair. Flow regulated by Melones Reservoir (see 

preceding page) and Relief, Donnells, Hartley, Lyons, and Strawberry Reservoirs 

(combined capacity, 312,300 acre-ft). Several diversions above station. Backwater 

from Tullock Reservoir affects record at times since storage began on Nov. 25, 1957.

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

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

Records available . February 1957 to September 1958. Records equivalent to those published as Stanislaus River at Knights Ferry 1903-14, and as Stanislaus River near 

Knights Ferry 1915-32, if adjusted for diversion in Stanislaus and San Joaquin 

Water Co.'s canal, and Oakdale and South San Joaquin canals.

Gage.--Water-stage recorder. Datum of gage is 252.83 ft above mean sea level (levels by 

Oakdale and South San Joaquin Irrigation Districts).

Extremes.--Maximum discharge during year, 12,200 cfs Apr. 4 (gage height, 17.25 ft), 

from rating curve extended above 6,000 cfs by logarithmic plotting; minimum daily, 

0.4 cfs Oct. 1-12.

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

unknown) by computation of flow over Goodwin Dam.

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

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

Joaquin Canal (see p. 383) and Oakdale Canal (see p. 384) divert at Goodwin Dam 

1.0 mile upstream.

SAN JOAQDIN RIVER BASIN 387

3035. San Joaquin River near Vernalis, Calif.

Location. Lat 37°40'34", long 121°15'51", on left bank 30 ft upstream from Durham Ferry 

highway bridge, 3 miles downstream from Stanislaus River, and 3.4 miles northeast of 

Vernalis, San Joaquin County.

Drainage area. 14,010 sqmi, approximately.

Records available.--July 1922 to September 1958 (1922-23 and 1925-29, low-water records 

only)".

Gage. Water-stage recorder. Datum of gage is 8.4 ft above datura of Corps of Engineers. 

July 1922 to September 1946 at various sites on or within 100 ft of Durham Ferry 

bridge. Prior to Apr. 1, 1931, at different datum.

Average discharge.--30 years (1923-24, 1929-58), 4,883 cfs (3,535,000 acre-ft per year).

Extremes.--Maximum discharge during year, 41,400 cfs Apr. 5 (gage height, 26.60 ft); minimum, 1,400 cfs Aug. 14.

1922-58: Maximum discharge recorded, about 79,000 cfs Dec. 9, 1950 (gage height, 

27.75 ft), Including flow through breaks in levee; minimum, 184 cfs Aug. 14, 1931.

Remarks. Records good except those for period of indefinite stage-discharge relation, 

which are fair. Natural flow of stream affected by storage reservoirs, power developments, ground-water withdrawals, and diversions for irrigation; low flows consist 

mainly of return flow from irrigated areas. Records of chemical analyses, suspended 

sediment loads, and water temperatures for the water year 1958 are given in WSP 1574.

3130. Delta-Mendota Canal near Tracy, Calif.

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 1958.

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. 7 years, 1,116 cfs 3,000 acre-ft per year).

Extremes.--1951-58: Maximum daily discharge, 4,418 cfs Feb. 9, 1957; no flow several 

months each year.

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 

Friant Dam. The canal is a part of Central-Valley project. Records of chemical analyses for the water year 1958 are given in WSP 1574.

Cooperation. Records of daily discharge and six discharge measurements furnished by 

Bureau of Reclamation and reviewed by Geological Survey.

Discharge, In cubic feet per second, water year October 1957 to September 1958

Records available.--October 1907 to September 1958.

Gage. Water-stage recorder. Datum of gage is 168.09 ft above mean sea level, datum of 

1929. Prior to July 10, 1930, staff gage at same site and datum.

Average discharge.--51 years, 495 cfs (358,400 acre-ft per year).

Extremes. Maximum discharge during year, 29,300 cfs Apr. 3 (gage height, 12.18 ft); minimum, 12 cfs Oct. 11.

1907-58: Maximum discharge, 42,000 cfs Dec. 23, 1955 (gage height, 14.59 ft), from 

rating curve extended above 6,000 cfs on basis of comparison with upstream and downstream peaks and velocity-area studies; no flow parts of many years.

Flood in March 1907 reached a stage of 16.3 ft.

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

good. Numerous small diversions above station for irrigation and mining. Records of 

chemical analyses for the water year 1958 are given in WSP 1574.

Records available.--October 1943 to September 1958 in reports of Geological Survey. In 

reports of California Department of Water Resources 1931-40, 1941-42 (gage heights 

only during high-water periods), and 1942-58.

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

Average discharge. 15 years, 587 cfs (425,000 acre-ft per year); median of yearly mean 

discharges, 450 cfs (326,000 acre-ft per year).

Extremes.--Maximum discharge during year, 32,600 cfs Apr. 3 (gage height, 46.10 ft); no 

flow Oct. 1-9, Sept. 5-26.

1943-58: Maximum discharge, 54,000 cfs Dec. 23, 1955 (gage height, 46.26 ft), from 

rating curve extended above 36,000 cfs by logarithmic plotting; no flow during parts 

of each year.

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

and those for period of indefinite stage-discharge relation, which are poor. Diversions for irrigation of about 2,100 acres between stations at Michigan Bar and at 

McConnell. Records of suspended sediment loads for the water year 1958 are given in 

WSP 1574.

1909-58: Maximum discharge, about 3,000 cfs Mar. 1, 2, 1910, from rating curve 

extended above 1,200 cfs; no flow at times.

Revisions.--Maximum discharge observed for the water year 1918 has been revised to 

24 cfs May 29, 1918 (gage height, 0.82 ft), superseding figure published in WSP 481.

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

which are poor. Records herein, except average discharge, not adjusted for diversion 

by North Drew Canal. Since 1912, flow regulated by Drew Reservoir (capacity, 62,500 

acre-ft). Diversions for irrigation of 3,100 acres above station, and since March 

1914, North Drew Canal has diverted above station for irrigation of lands west of 

Lakeview.

424 GOOSE LAKE BASIN

3400. Cottonwood Creek near Lakeview, Oreg.

Location.--Lat 42°14', long 120°30', in SW^ sec.29, T.38 S., R.19 E., on right bank

600 ft downstream from Cottonwood Creek Dam and 9 miles (revised) northwest of Lakeview.

Drainage area.--30 sq mi, approximately.

Records available.--November 1908 to September 1919 and October 1925 to September 1958 in 

reports of Geological Survey. November 1908 to September 1919 and October 1924 to 

September 1941 in reports of State engineer.

Gage.--Water-stage recorder. Datum of gage is 5,006.93 ft above mean sea level (levels 

oy Bureau of Reclamation). Prior to June 1, 1919, and Apr. 13, 1924, to June 3, 1932, 

staff gage at several sites within half a mile downstream from reservoir at different 

datums. June 1 to Sept. 30, 1919, water-stage recorder near present site at different 

datum.

Average discharge.--37 years (1909-19, 1924-35, 1938-42, 1946-58), 21.9 cfs (15,850 

acre-ft per year) .

Extremes. 1928-29: Maximum discharge observed during water year, 48 cfs May 22, 24-27; 

maximum gage height, 1.82 ft May 24-26; minimum discharge observed, 0.4 cfs Aug. 12 

to Sept. 7, but may have been less during periods of ice effect.

1957-58: Maximum discharge during water year, 268 cfs May 11 (gage height, 4.54 ft); 

no flow Sept.4,5.

1908-19, 1924-58: Maximum discharge, between 500 and 1,000 cfs during period 

Apr. 26 to May 1, 1927, when natural flow, estimated as 170 cfs, was augmented by 

water escaping from reservoir through break in outlet conduit near control gates; no 

flow at times.

Revisions.--Maximum discharge for water year 1937 has been revised to 143 cfs sometime during period Apr. 16 to May 2, 1937 (gage height, 3.24 ft), superseding figure 

published in WSP 831.

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

Since 1923 flow regulated by Cottonwood Creek Reservoir (capacity, 4,160 acre-ft). 

Diversions for irrigation of 270 acres above station.

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

 1910-11, 1919, and 1929, superseding those published in WSP 311, 370, 511, and 691, 

are given herein. A complete table of daily discharge is given for the water year 

1929, but only revised discharges are given for other water years.

downstream from Keswick, and 10 miles downstream from Shasta Dam.

Drainage area.--6,710 sq mi, approximately, excluding Goose Lake basin.

Records available. October 1938 to September 1958.

Gage.--Water-stage recorder. Datum of gage is 479.81 ft above mean sea level, datum of 

1^929. Prior to Oct. 1, 1939, at site 1.5 miles upstream at datum 20.2 ft higher and 

Oct. 1, 1939, to Apr. 30, 1942, at site 1.5 miles upstream at datum 15.2 ft higher.

Average discharge.--18 years (1939-41, 1942-58), 8,547 cfs (6,188,000 acre-ft per year), 

adjusted for storage since 1943 and evaporation since 1947.

Extremes.--Maximum discharge during year, 78,800 cfs Feb. 21 (gage height, 31.55 ft); minimum, 3,900 cfs Nov. 4.

1938-43 (prior to regulation by Shasta Lake); Maximum discharge, 186,000 cfs Feb.28, 

1940 (gage height, 47.2 ft, site and datum then in use), from rating curve extended 

above 75,000 cfs on basis of peak discharge at Kennett plus 4,000 cfs estimated inflow; 

minimum observed, 2,730 cfs Aug. 22, 1959.

1944-58: Maximum discharge, that of Feb. 21, 1958; minimum, 154 cfs May 15, 1948.

Remarks. Records excellent. Flow regulated by Shasta Lake beginning Dec. 30, 1943 (see 

preceding page). Diurnal fluctuations from Shasta powerplant re-regulated by Keswick 

Reservoir (capacity, 4,170 acre-ft between normal operating elevations 579.0 and 

586.0 ft) and powerplant. No diversions for irrigation between Shasta Dam and station 

at Keswick. Records of chemical analyses for the water year 1958 are given in WSP 1574.

Cooperation.--Six discharge measurements furnished by Bureau of Reclamation.

Remarks.--Records fair, except those for period of doubtful or no gage-height record, 

which are poor. Many diversions above station for irrigation. Flow regulated by 

East Park Reservoir (usable capacity, 50,600 acre-ft and Stony Gorge Reservoir (usable 

capacity, 50,100 acre-ft). Prior to October 1956, figures of daily discharge included 

water diverted to South Diversion Canal, which diverts 120 ft above station. Records 

of combined monthly discharge do not include a small diversion that bypasses the 

station at times for irrigation. Records of suspended sediment loads for the water 

year 1958 are given in WSP 1574.

3995. North Pork Feather River near Prattville, Calif.

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

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

upstream from Butt Creek. 

Drainage area.--507 sq mi. 

Records available.--June 1905 to September 1958 (daily discharges for July 1921 to September 1936 include water diverted through Almanor-Butt Creek tunnel). 

Gage.--Water-stage recorder and 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 . 52 years (1905-10, 1911-58), 901 cfs (652,300 acre-ft per year),

including diversion through Almanor-Butt Creek tunnel.

Extremes.--Maximum discharge during year, 2,300 cfs Apr. 13 (gage height, 6.43 ft); mini- 

 mum daily, 10 cfs Jan. 11, 12, 14-19. Extremes do not include diversions through

Almanor-Butt Creek tunnel.

1905-58: 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. Plow regulated by Lake Almanor beginning in 1913 (see preceding page). Water is diverted for power from Lake Almanor through Almanor-Butt

Creek tunnel to Butt Creek. Figures of daily discharge show flow at river only; monthly

figures also show combined flow of river and tunnel. 

Cooperation.--Water-stage-recorder graph and seven discharge measurements 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

4085. Middle Yuba River at Milton, Calif.

Location.--Lat 39°31'22", long 120°35'01", in SW£ sec.12, T.19 N., R.12 E., on right 

bank at diversion dam of Nevada Irrigation District, at old townsite of Milton, 

4 miles southeast of Sierra City and 8 miles upstream from South Fork of Middle Yuba 

River.

Drainage area. 39.5 sq mi.

Records available.--December 1925 to September 1934, October 1935 to September 1958. 

Prior to October 1949, published as "Middle Fork Yuba River."

Gage.--Water-stage recorder and concrete spillway control. Altitude of gage is 5,700 ft 

[from topographic map). Prior to June 8, 1928, at site 0.2 mile downstream at different datum.

Average discharge.--28 years (1926-30, 1931-34, 1935-40, 1941-42, 1943-58), 112 cfs 

(81,080 acre-ft per year), based on combined flow of Middle Yuba River at this station and Milton-Bowman tunnel at outlet.

Extremes.--Maximum discharge during year, 1,300 cfs May 23 (gage height, 1.52 ft); no 

flow over dam for long periods.

1925-34, 1935-58: 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. 506).

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

Revisions.--WSF 1395: Drainage area.

Remarks. Records excellent except those above 50,000 cfs, which are good. Discharge 

measurements generally made two or more times a month. Flow regulated by Shasta Lake 

beginning Dec. 30, 1943, several other reservoirs and powerplants above station, and 

by bypassing for flood control. Many diversions above station for irrigation. When 

discharge exceeds about 55,000 cfs, flow begins over Fremont weir (Just upstream) into 

Yolo bypass (see p. 558). Elevation of crest of Fremont weir is 33.5 ft (datum of 

Corps of Engineers).

Cooperation. Sixteen discharge measurements furnished by California Department of Water 

Resources.

Discharge, In cubic feet per second, water year October 1957 to September 1958,

1909, to Dec. 7, 1911, staff gage at site 30 ft downstream at different datum.

Extremes. Maximum discharge during year, 2,940 cfs Feb. 24 (gage height, 7.83 ft), from 

rating curve extended above 1,200 cfs on basis of slope-area measurement at gage 

height 19.2 ft; minimum daily, 3.3 cfs Oct. 11-12, 20-22.

1909-11, 1956-58: Maximum discharge, that of Feb. 24, 1958; minimum daily, 2 cfs 

Nov. 4-8, 1910.

Flood of Dec. 23, 1955, reached a stage of 19.2 ft, from floodmarks, present site 

and datum (discharge, 11,700 cfs, from slope-area measurement of peak flow).

Remarks. Records fair. Flow regulated, beginning in 1884, by Loon Lake (usable capacity, 

8,000 acre-ft) on Gerle Creek where most of stored water is diverted out of watershed 

in Georgetown Divide ditch (see p. 529, 530).

Location. Lat 38°46'20", long 120°42i05", in SE^NW^ sec. 25, T.ll H. , R.ll E. , on right 

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 1958. Prior to October 1956, records for 

river and conduit published separately.

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

1950, to Dec. 5, 1951, staff gage at same site and datum.

Average discharge. 36 years, 974 cfs (705,100 acre-ft per year), combined flow of South 

Pork American River near Camino and American River flume.

Extremes (river only). Maximum discharge during year, 8,350 cfs May 23 (gage height, 

13.42 f t) ; minimum daily, 3.8 cfs Dec. 5.

1922-58: Maximum discharge, 49,800 cfs Dec. 23, 1955 (gage height, 32.6 ft, from 

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

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

Remarks. --Records good. Records of daily discharge presented 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 H. , R.ll E., for power development; water is 

returned to river at Rock Creek powerhouse 5.4 miles below station. Plow partly 

regulated by four reservoirs since beginning of record (total usable capacity, 37,100 

acre-ft). Water diverted by El Dorado Canal used for power and returned to river 

above station except for about 40 cfs, May to October, and about 7 cfs for remainder

December 1890 to September 1958 (gage heights only) in reports of U. S. Weather Bureau.

Gage .--Water-stage recorder. Datum of gage is at mean sea level. Prior to Oct. 15, 1912, 

staff gage in vicinity of I Street Bridge. Oct. 15, 1912, to Nov. 16, 1956, waterstage recorder at various sites in vicinity of I Street Bridge. Prior to Nov. 16, 

1956, datum of gages at low-water mark of Oct. 23, 1856, 0.12 ft above mean sea level, 

and at 3.10 ft, Corps of Engineers datum.

upstream at different datum.

Average discharge.--36 years, 204 cfs (147,700 acre-ft per year).

Extremes.--1922-58: Maximum daily discharge, 348 cfs Apr. 24, 1953; no flow at times 

several years.

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

good. Water is diverted from Eel River above Van Arsdale Dam. After passing through 

powerhouse, part of it is used for irrigation in Potter Valley and remainder flows 

into East Fork Russian River. Water for irrigation diverted from tailrace is included 

in figures of discharge.

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

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

Revisions (water years).--WSP 1395: 1950.

LOST RIVER BASIN 609

4860. Lost River diversion canal near Olene, Oreg.

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

Lost River Dam, 4 miles southwest of Olene.

Records available.--May 1912 to September 1958. Published as "near Klamath Falls" 1916-18.

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

once daily. Altitude of gages is 4,080 ft (from topographic map). Mar. 29, 1916, 

to Apr. 22, 1918, and at times during period May 4, 1923, to Sept. 30, 1933, waterstage recorders within 1 mile downstream at different daturas.

Average discharge.--42 years (1912-15, 1919-58), 159 cfs (115,100 acre-ft per year). 

Extremes. 1912-58: Maximum daily discharge, 2,860 cfs Jan. 16, 1956; no flow at times.

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

gates with variable coefficient determined by discharge measurements. Canal diverts 

water from Lost River and discharges into Klamath River to aid in reclamation of Tule 

Lake. Discharge includes water occasionally wasted from "C" Canal flume below intake 

(none during 1958 water year). Beginning in July 1951, records include pumpage by 

Miller Hill pumping plant which operates at times; during period May through August 

1958, pumpage amounted to 4,950 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. 620.)

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

Discharge, In cubic feet per second, water year October 1957 to September 1958

5050. Cascade Canal near Pish Lake, Oreg.

Location.--Lat 42°24'20", long 122°16'05", in SE^ sec.30, T.36 S., R.5 E., on left bank 

at divide between Rogue River and Klamath River basins, 3 miles upstream from Pish 

Lake and 8.5 miles (revised) downstream from point of diversion.

Records available. June 1924 to September 1958'(irrigation seasons only, 1956 fragmentary).

Gage. Water-stage recorder. Altitude of gage is 5,235 ft (by barometer). Prior to 

May 26, 1926, staff gage and May 26, 1926, to June 26, 1954, water-stage recorder, 

at datum 0.39 ft lower.

Extremes.--1924-58: Maximum daily discharge, 58 cfs July 25, 26, Aug. 8-10, 1955, June 6,

Remarks.--Records poor. Water stored in Pourmile Lake was released to canal during 

period Sept. 8-30. Canal diverts water from Fourmile Creek, in Klamath River basin, 

in sec.9, T.36 S., R.5 E., and discharges into lava bed l| miles above Pish Lake, in 

Rogue River basin. Also some runoff from melting snow intercepted and diverted. Entire 

flow sinks in lava bed, reappearing in springs at head of Pish Lake.

Lake).

Records available.--May 1904 to September 1958.

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

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

Average discharge.--54 years, 1,622 cfs (1,174,000 acre-ft per year).

Extremes.--Maximum discharge during year, 6,690 cfs Mar. 5: minimum daily, 561 cfs Aug. 20.

1904-58: 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. Regulation since April 1919 by Upper Klamath Lake (see preceding 

page). Water diverted above station by main or "A" Canal of Klamath project (see 

p. 617). Many other diversions above lake. All records presented herein include flow 

in Keno Canal which, since September 1908 (corrected), has diverted from Upper Klamath 

Lake at Link River Dam, 4,800 ft above station, for power generation, and returns flow 

to Link River 600 ft below station.

Revisions.--Figure of discharge for June 25, 1907, has been revised to 3,440 cfs, superseding that published in WSP 370.

620 KLAMATH RIVER BASIN

5085. 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 1958. Published with 

records for Lost River diversion canal near Olene in 1931.

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

4,080 ft (from topographic map).

Average discharge.--28 years, 32.2 cfs (23,310 acre-ft per year).

Extremes. 1931-58: 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. 609). 

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. Since 1949 records include water removed from the 

diversion canal by Miller Hill pumping plant (capacity, 70 cfs).

Cooperation. Records furnished by Bureau of Reclamation; reviewed by U. S. Geological 

Survey.

basins].

Records available. June 1904 to December 1913, January 1930 to September 1958.

Gage. Water-stage recorder. Altitude of gage is 3,970 ft (from river-profile map).

June 1, 1904, to Dec. 31, 1913, staff or hook gage at site 2 miles upstream at different datum. Jan. 28, 1930, to Sept. 30, 1931, water-stage recorder at site 20 ft downstream at datum 2.72 ft higher and Oct. 1, 1931, to July 26, 1932, at datum 0.72 ft 

higher. July 27, 1932, to Nov. 5, 1954, water-stage recorder at site 5 ft upstream at 

datum 0.72 ft higher.

Average discharge. 37 years, 1,723 cfs (1,247,000 acre-ft per year).

Extremes. Maximum discharge during year, 7,470 cfs Mar. 3 (gage height, 11.20 ft); minimum, 147 cfs Aug. 20 (gage height, 2.96 ft); minimum daily, 915 cfs May 4.

1904-13, 1930-58: Maximum discharge, that of Mar. 3, 1958; minimum, 26 cfs Sept. 23, 

1956; minimum daily, 60 cfs May 19, 1934.

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

(discharge, 9,250 cfs).

Remarks.--Records excellent. Flow regulated by dam at outlet of Upper Klamath Lake since 

1919 and by low dam on Klamath River at Keno since 1931. Diversions for irrigation 

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

station (see records for Lost River diversion canal near Olene, p. 609, and diversion 

from Klamath River to Lost River near Olene, preceding page). Diversions through 

Midland Canal (since 1947) to Klamath Drainage District and through Klamath Strait 

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

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

Reclamation from hours of pump operation.

662 DISCHARGE AT PARTIAL-RECORD STATIONS AND MISCELLANEOUS SITES

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

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

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

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

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

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

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

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

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

are called measurements at miscellaneous sites.

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

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

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

table.

Low-flow partial-record stations

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

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

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

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

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

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

DISCHARGE AT PARTIAL-RECORD STATIONS AND MISCELLANEOUS SITES 663

Crest-stage partial-record stations

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

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

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

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

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

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

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

water years for which the annual maximum has been determined. The maximum discharge for 

each year since the crest-stage gage was established is given. The peak discharge for 

some years may have been published in a previous report as a measurement of discharge. 

Figures given herein supersede all previous figures of peak discharge for the floods
