SURFACE WATER SUPPLY OF THE PACIFIC SLOPE 

BASKS IN CALIFORNIA, 1913.

AUTHORIZATION AND SCOPE OP WORK.

This volume is one of a series of 12 reports presenting results of 

measurements of flow made on streams in the United States during 

1913. Six of the reports for 1913 contain data for the year ending 

September 30, and the other six for the calendar year, as indicated 

in the table on page 10.

The data presented in these reports were collected by the United 

States Geological Survey under authority implied in the organic law 

(20 Stat. L., p. 394), which contains the following paragraph:

Provided, That this officer [the Director] shall have the direction of the geological 

survey and the classification of public lands, and examination of the geological structure, mineral resources, and products of the national domain.

The work was begun in 1888 hi connection with special studies of 

water supply for irrigation. Since the fiscal year ending June 30, 

1895, successive sundry civil bills passed by Congress have carried 

the following item and appropriations:

For gaging the streams and determining the water supply of the United States, 

and for the investigation of underground currents and artesian wells, and for the 

preparation of reports upon the best methods of utilizing the water resources:

Annual appropriations for the fiscal years ending June SO, 1895-1913.

1908 to 1910, inclusive....................................... 100,000

1911 to 1913, inclusive....................................... 150,000

In the execution of the work many private and State organizations have cooperated, either by furnishing data or by assisting in 

collecting data. Acknowledgments for cooperation of the first kind 

are made in connection with the description of each station affected 

and of the second kind on page 20.
10 SUEFACE WATEE SUPPLY, 190.3, PART XI.

Measurements of stream flow have been made at about 3,000 

points in the United States and also at many points in small areas 

in Seward Peninsula and the Yukon-Tanana region, Alaska, and in 

the Hawaiian Islands. In July 1913, 1,388 gaging stations were 

being maintained by the Surrey and the cooperating organizations 

in the United States and many miscellaneous discharge measurements were made at other points. In connection with this work, data 

were also collected in regard to precipitation, evaporation, storage 

reservoirs, river profiles, and water-power in many sections of the 

country, and will be made available in the regular water-supply 

papers from time to time.

PUBLICATIONS.

A report has been prepared for each year embodying the streamflow data collected during that year. An index to the reports containing stream-flow measurements prior to 1904 has been published 

as Water-Supply Paper 119.

Prior to 1901 gage heights and discharge measurements were published in water-supply papers or bulletins, and estimates of monthly 

discharge in annual reports; since 1901 both classes of data have 

been published in water-supply papers, and they are now being published in 12 parts, as shown in the following table:

NOTE. No data regarding stream flow are given in the 15th and 17th annual reports.

The table on page 12 gives, by years and drainage basins, the numbers of the papers on surface water supply published from 1899 to 

1913. The data for any particular station will be found in the 

reports covering the years during which the station was maintained. 

For example, data for any station in the area covered ay Part I are 

published in Water-Supply Papers 97, 12*, 165, 201, 241, 261, 281, 

301, 321, and 351, which contain records for the New England 

streams from 1903 to 1913. The year covered by the report is indicated at the head of the column in which the paper is listed.

DEFINITION OP TERMS.

.The volume of water flowing in a stream the "run-off" or "discharge" is expressed in various terms, each of which has become 

associated with a certain class of work. These terms may be divided 

into two groups: (1) Those which represent a rate of flow, AS secondfeet, gallons per minute, miner's inches, and discharge in secondfeet per square mile; and (2) those which represent the actual 

quantity of water, as run-off in depth in inches, acre-feet, and millions of cubic feet. The units used in this series of reports are secondfeet, second-feet per square mile, run-off in inches, acre-feet, and 

millions of cubic feet. They may be defined as follows:

"Second-foot" is an abbreviation for "cubic foot per second," 

and is a unit for the rate of discharge of water flowing in a stream.
14 SURFACE WATER SUPPLY, 1913, PART XI.

A second-foot is the rate of discharge of water flowing in a channel 

of rectangular cross section, 1 foot wide and 1 foot deep, at an average velocity of i foot a second. It is generally used as a v fundamental unit from which others are computed by the use of the factors given in the tables of convenient equivalents (p. 15).

"Second-feet per square mile" is the average number of cubic feet 

of water flowing per second from each square mile of area drained, 

on the assumption that the run-off is distributed uniformly both as 

regards time and area.

"Run-off (depth in inches)" is the depth to which the drainage 

area would be covered if all the water flowing from it in a given 

period were conserved and uniformly distributed on the surface. 

It is used for comparing run-off with rainfall, which is usually 

expressed in depth in inches.

An "acre-foot" is equivalent to 43,560 cubic feet and is the 

quantity required to cover an acre to the depth of 1 foot. The 

term is commonly used in connection with storage for irrigation.

"Millions of cubic feet" is a unit used to express quantities of 

water stored in reservoirs, and is most frequently used in studies of 

flood control.

The following terms used in these reports are not in common use 

and may be defined as follows:

"Control," "controlling section," and "point of control" are terms 

used to designate that cross section of the stream below the gage 

which controls or regulates the height of the water surface at the 

gage. It should be noted that the control may not be the same 

cross section at all stages.

"Discharge relation" is an abbreviation for the term "relation of 

gage height to discharge."

The "point of zero flow" for a given gaging station is that point 

on the gage the gage height to which the surface of the river 

would fall if there were no flow.

EXPLANATION OF DATA.

For each regular current-meter gaging station the following data 

are given: Description of the station, list of discharge measurements, 

table of daily gage height, table of daily discharge, table of monthly 

and yearly discharge and run-off. For stations located at weirs or 

dams the gage-height table is usually omitted.

In addition to statements regarding the location and equipment 

of current-meter stations, the descriptions give information in regard 

to any conditions which may affect the constancy of the discharge 

relation covering such points as ice, logging, shifting channels, and 

backwater; also information regarding diversions which decrease 

the total flow at the measuring section. Statements are also made 

regarding the accuracy of the data and computed results.

The table of daily gage height shows the daily fluctuations of the 

surface of the river as found from the mean of the gage readings 

taken each day, usually in the morning and in the evening, though 

at many stations only one reading is made each day. At a comparatively few stations automatic gages are used, some of which 

give a continuous record of river stage in the form of a hydrograph, and others a record printed at regular intervals, from which 

the mean daily gage height can be computed. The gage height 

given in the table represents the elevation of the surface of the 

water above the zero of the gage. When the discharge relation is 

affected by the presence of ice in the streams or by backwater from

40967° WSP 361 16 2
18 SURFACE WATER SUPPLY, 1913, PART XI.

obstructions, gage heights are published as recorded, with suitable 

footnotes. The rating table is not applicable for such periods unless 

the proper corrections to the gage heights are known and applied. 

Attention is called to the fact that the zero of the gage is placed at 

an arbitrary datum and has no relation to zero flow or the bottom of 

the river. In general the zero is located somewhat below the lowest 

known stage to avoid negative readings.

In the tables of daily gage height the use of zeros in the hundredths 

place indicates the degree of refinement to which the gage was read 

and to which the mean daily gage height was computed. If a gage is 

read to tenths or half-tenths once a day or to tenths twice a day no 

zeros appear in the hundredths place for any stage. If the gage is read 

to half-tenths twice a day or to quarter-tenths or hundredths, regardless of the number of readings a day, the gage heights are published to 

hundredths, and zeros appear in the hundredths place, below a certain 

limiting stage. This limiting stage is so selected that the average 

errer in the mean daily discharge, resulting from not using the mean 

daily gage height to hundredths above that stage, shall not be greater 

than 2 per cent. For automatic gages the allowable average error of 

the daily discharge has been taken as 1 per cent. The selection of the 

percentage is arbitrary, but it should be noted that the maximum error 

will in all cases be twice the average error. In like manner halftenths are used from the hundredths limit to another higher limit, 

above which only tenths are used. It is the aim to have .the gageheight observations at each gaging station recorded to the degree of 

refinement required by the above-described method of use, but in 

practice it is often found necessary, in order to avoid confusion in the 

gage observer's record, to have the observations for all stages recorded 

to the degree of refinement required for low stages, which usually 

necessitates readings to hundredths of a foot.

The discharge measurements and gage heights are the base data 

from which rating tables, daily discharge tables, and monthly discharge tables are computed.

The rating table gives, either directly or by interpolation, the discharge in second-feet corresponding to every stage of the river 

recorded during the period for which it is applicable. It is not published in this report, but can be determined from the tables of daily 

gage height and daily discharge by plotting gage heights in feet as 

ordinates and discharge in. second-feet as abscissas.

The table of daily discharge determined from the rating table 

gives the discharge in second-feet corresponding to the mean of the 

gage readings observed each day.

The base data presented in this report, unless otherwise stated in 

the description of the station,'have been collected by the methods
ACCITEACT OF FIELD DATA AND COMPUTED EESULTS. 19

 commonly used at current-meter gaging stations and described, in 

standard textbooks.

In the table of monthly discharge the column headed "Maximum" 

gives the mean flow, as determined from the rating table, for the day 

when the mean gage height was highest. As the gage height is the 

mean for ,the day, it does not indicate correctly the stage when the 

water surface was at crest height, and the corresponding discharge 

was consequently larger than given in the maximum column. Likewise, in the column of "Minimum" the quantity given is the mean 

flow for the day when the mean gage height was lowest. The column 

headed "Mean" is the average flow in cubic feet for each second 

during the month. On this the computations for the remaining columns, which are defined on pages 14 and 15, are based.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS.

The accuracy of stream-flow data depends on (1) the permanence of 

channel and of the relation between discharge and stage, and (2) on 

the accuracy of observation of stage, measurements of discharge, 

and interpretation of data.

In order to give engineers and others information regarding the 

probable accuracy of the computed results, footnotes are added to 

the daily discharge tables, stating the probable accuracy of the rating 

curves used, and an accuracy column is inserted in the monthly discharge table. For the rating curves "well defined" indicates, in 

general, that the rating is probably accurate within 5 per cent; 

"fairly well defined," within 10 per cent; "poorly defined" of "approximate," within 15 to 25 per cent. These notes are very general 

and are based on the plotting of the individual measurements with 

reference to the mean rating curve.

The accuracy column in the monthly discharge table does not apply 

to the estimate of maximum or minimum discharge nor to that for 

any one day, but to the monthly mean. It is based on the accuracy 

of the rating, the probable reliability of the observer, the number of 

gage readings per day, the range of the fluctuation in stage, and 

knowledge of local conditions. In this column A indicates that the 

mean monthly flow is probably accurate within 5 per cent; B, within 

10 per cent; C, within 15 per cent; D, within 25 per cent. Special 

conditions are covered by footnotes.

Even though the monthly means for any station may represent 

with a high degree of accuracy the quantity of water flowing past the 

gage, the figures showing discharge per square mile and depth of runoff in inches may be subject to gross errors which result from including in the measured drainage area large noncontributing districts*or 

omitting estimates of water diverted for irrigation or other use. 

"Second-feet per square mile" and "run-off, depth in inches" have, 

therefore, not been computed for streams draining areas in which
20 SURFACE WATER SUPPLY, 1913, PART XI.

the annual rainfall is less than 20 inches, nor for streams draining 

areas in which the precipitation exceeds 20 inches if such computations might be uncertain or misleading because of the presence of 

large noncontributing districts in the measured drainage area, of 

the omission of estimates of water diverted for irrigation or other use, 

or of artificial control or unusual natural control of the flow of the river 

above the gaging station. All values of "second-feet per square 

mile" and "run-off, depth in inches'.' previously published by the 

Survey should be used with extreme caution, and such values in this 

report should be used with care because of possible inherent sources 

of error not known to the Survey.

In general the base data collected each year by the Survey engineers are published, not only to comply with the law, but also to afford 

any engineer the means of analyzing in detail the results of the computations. The table of monthly discharge is so arranged as to give 

only a general idea of the flow at the station and should not be used 

for other than preliminary estimates. The tables of daily discharge 

allow more detailed studies of the variation in flow. It should be 

borne in mind, however, that the observations in each succeeding year 

may be expected to throw new light on data already collected and 

published.

COOPERATION.

The hydrographic work of the United States Geological Survey in 

California is being carried on in cooperation with the State in accordance with acts of the State legislatiure, approved March 16, 1903, 

March 20, 1905, March 11, 1907, and April 22, 1909, empowering the 

State authorities to enter into contracts with the Director of the 

United States Geological Survey for the purpose- of making topographic maps, gaging streams, surveying reservoir sites and canal 

locations, for the conservation and utilization of the flood and storm 

waters of the State.

The cooperative agreements with the Conservation Commission 

and the State Board of Control (Water Power) of the State of California, signed in September, 1911, continue in force. The funds contributed by these commissions during the year were expended mainly 

in maintenance of stations previously established and in the installation of water-stage recorders.

The members of the Conservation Commission are George C. 

Pardee (chairman), Francis Cuttle, and J. P. Baumgartner. The 

members of the State Water Commission are Hiram W. Johnson 

(governor), Charles D. Marx (chairman), S. C. Graham, Harold T. 

Power, and W. F. McClure (State engineer).

The work in the Klamath River basin in Oregon was carried on in 

cooperation with the United States Reclamation Service, which furnished the field data.

GAGING STATION RECORDS. 

TIA JTJANA RIVER BASIN.

COTTONWOOD CREEK NEAR DULZURA, 1 CAL.

LOCATION. In the SW. J sec. 15, T. 17 S., R. 3 E., at Barrett dam site, 1J miles below 

intake of Dulzura conduit, about 17 miles northeast of Dulzura. Pine Valley 

Creek enters 1 mile and Lyons Creek half a mile above the station.

RECORDS AVAILABLE. December 15,1905, to September 30, 1913.

DRAINAGE AREA. 246 square miles, revised estimate; area measured on military 

survey and United States Geological Survey topographic maps.

GAGE. Two vertical staffs. Upper gage is on left bank near end of dam and indicates depth of water on the crest; lower gage, which is on upstream side of dam 

between flume and right bank, is read when no water is flowing over crest of dam; 

its datum is 2.50 feet lower than that of the upper gage. The upper gage was not 

used during 1912 and 1913.

CHANNEL. Shifting sand above dam.

DISCHARGE.MEASUREMENTS. Made at low concrete dam back of which sand and 

gravel have been deposited to the level of its crest. At low stages the flow is 

restricted to a rectangular wooden flume through the wall of the dam, but at 

high stages water passes over the entire length of the dam, which is 61 feet. 

Measurements are made by wading, except at high stages, when only float measurements have been obtained.

DIVERSIONS. Dulzura conduit diverts water from Cottonwood and Pine Valley 

creeks, about half a mile above their junction, into the Dulzura Creek drainage 

basin. From the end of the conduit the water flows down the natural channel of 

Dulzura Creek into the Lower Otay reservoir. The water is used for munic.ipal 

supply at San Diego. The conduit is 13.38 miles long and is concrete lined 

except 4,490 feet of flume and 9,219 feet of tunnel. The average width is about 

5 feet and the depth 4 feet 2 inches. The grade is 4 feet in 5,000 and the capacity 

40,000,000 gallons in 24 hours. Loss by seepage between intake and measuring 

weir is estimated at about 3 per cent.

In the fall of 1912 the city of San Diego voted to purchase this water system, 

exclusive of the Morena reservoir ? from the Southern California Mountain Water 

Co. The system was turned over to the city February 1,1913. Morena reservoir 

was leased for 10 years.

STORAGE. The Morena reservoir, about 9 miles above the Barrett dam site, has a 

capacity of 46,000 acre-feet. On October 1, 1913, there were 1,162 acre-feet 

impounded in the reservoir.

i Formerly described as "near Jamul."
22 SURFACE WATEfl SUPPLY, 1913, PAET XI.

ACCURACY. Daily discharge originally computed in gallons per day by city of San 

Diego from rating curve prepared by. Geological Survey. Kesults considered 

good.

COOPERATION. Estimates of daily discharge in gallons furnished by the department 

of water, city of San Diego, through H. A. Whitney, hydraulic engineer.

The following discharge'measurement was made by H. D. McGlashan: 

April 16, 1913: Gage height, 0.23 foot; discharge, 2.3 second-feet.

CHANNEL. Sand and gravel; shifting.

DISCHARGE MEASUREMENTS. Made from cable at gage or by wading. 

DIVERSIONS. A small irrigation ditch (capacity, about one-third second-foot) heads

about 1,000 feet above station. 

ACCURACY. On account of the small number of discharge measurements made and

the shifting of the channel the results are only fair.

BOULDER CREEK AT CUYAMACA RESERVOIR, NEAR JULIAN, 1 CAL.

LOCATION. 100 feet below outlet gates of Cuyamaca reservoir, in Cuyamaca grant, 

12 miles above mouth of Boulder Creek, 7 miles south of Julian, and 22 miles 

northeast of Lakeside.

RECORDS AVAILABLE. June 19, 1912, to September 30, 1913.

i Formerly described as "near Lakeside." 

40967° WSP 361 16-; 3
34 SURFACE WATER SUPPLY, 1913, PAET XI.

DRAINAGE AREA. 12.0 square miles; measured on topographic maps.

GAGE. Vertical staff on right side of short flume 3| feet above 6-foot Cippoletti weir. 

, Zero of gage is at same elevation as crest of weir.

DISCHARGE MEASUREMENTS. Made by wading 50 feet below weir.

DIVERSION AND STORAGE. The Cuyamaca dam, completed in 1886, was one>of the 

first earth dams built in California for irrigation storage. The height as originally 

constructed was 35 feet. In 1894 the dam was enlarged, increasing the capacity 

of the reservoir to 11,400 acre-feet. The present dam is 635 feet long and 41£ 

feet high, having an inner slope of 2:1 and an outer slope of 1J:1. From the " 

reservoir the water flows down the natural channel of Boulder Creek and San 

Diego River to the intake of San Diego flume, a distance of 12J miles. The San 

Diego flume is more than 30 miles long, 6 feet wide, and 16 inches deep, and its 

capacity is about 16 second-feet. It discharges into La Mesa reservoir, about 

8 miles northeast of San Diego. This system supplied the city of San Diego 

with water until 1906, when the Sou them'California Mountain Water Co. extended 

its system to the city. It now supplies water for irrigation and domestic service. 

Area irrigated is about 4,000 acres. Seven per cent of the flow is used for domestic service. Water from the South Fork of San Diego River is diverted into this 

flume. The Capitan Grande Indian Reservation has a water right of 0.8 secondfoot from this flume.

ACCURACY. Rating curve is well defined; results are excellent.

COOPERATION. Weir installed and gage-height record furnished by Cuyamaca Water 

Co. through W. S. Post, engineer.

No discharge measurement made during the year.

Daily gage height, in feet, of Boulder Creek at Cuyamaca_Reservoir, near Julian, Cal., 

for the year ending Sept. 30, 1913.

BOULDER CREEK AT MOUTH, NEAR, LAKESIDE, CAL.

LOCATION. In the NW. \ sec. 12, T. 14 S., E. 2 E., 300 feet above junction with San

Diego River, about 14 miles northeast of Lakeside. 

RECORDS AVAILABLE. August 12, 1912, to September 30, 1913. 

DRAINAGE AREA. 33.5 square miles; measured on topographic maps. 

GAGE. Vertical staff in flume 8 feet above weir. When weir board is not in use a

vertical staff on left bank in pool above weir is read.
36 SURFACE WATER SUPPLY, 1913, PART XI.

DISCHARGE MEASUREMENTS. Made from foot plank over flume when weir board is 

not in use.

STORAGE. While water is being stored at Cuyamaca Reservoir, 12 miles above the 

station, the record shows only the run-off from the drainage area below the reservoir. A comparison of the flow at the outlet of the reservoir and at the mouth 

during the release of stored water will show approximately the loss by evaporation and seepage. There is practically no run-off from the intervening drainage 

area during the summer season. See also Boulder Creek at Cuyamaca Reservoir, 

near Lakeside, Cal.

ACCURACY. The weir is especially well constructed and results are excellent. On 

November 9, 1912, weir board was removed and since that date all gage readings 

refer to the upper gage. The rating curve for the flume is well denned. During 

the irrigation season the gage is read three times a day. For the remainder of the 

year daily readings are secured.

COOPERATION. Weir installed and gage-height record furnished by Cuyamaca Water 

Co., through W. S. Post, engineer..

ending Sept. 30, 1913.

38 SURFACE WATER SUPPLY, 1913, PART XI.

SAN DIEGO FLUME AT DIVERTING DAM, NEAR LAKESIDE, CAL.

LOCATION. In the SE. i sec. 11, T. 14 S.i, R. 2 E., at diverting dam about 13 miles

northeast of Lakeside.

RECORDS AVAILABLE. May 4, 1912, to September 30, 1913. 

GAGE. Vertical staff fastened to flume 500 feet below intake and a short distance

above sand box. A Sanders & Rising water-stage recorder is installed at same site. 

DISCHARGE MEASUREMENTS. Made from foot plank across flume at gage. 

ACCURACY. A well-defined rating table has been developed for periods when there

was little head on intake gate and these results are good. For periods when there

was considerable head on the intake gate, a rating curve averaging the discharge

measurements has been used. This curve has been used when the reservoir gage

read 8.00 feet or more, and results are fair. 

COOPERATION. Station maintained in cooperation with Cuyamaca Water Co., through

W. S. Post, engineer.

Discharge measurements of San Diego Flume at diverting dam near Lakeside, CaL, during the year ending Sept. 30, 1913.

SAN DIEGO FLUME NEAR LAKESIDE, OAL.1

LOCATION. One-fourth mile above trestle crossing at Los Coches Creek, about 3 miles

southeast of Lakeside.

RECORDS AVAILABLE. January 1, 1907, to September 30,1913. 

GAGE. Depth of water in flume is measured at reference point at patrolman's cabin.

On November 12, 1912, a Sanders & Rising water-stage recorder was installed at

same section.

1 See Boulder Creek at Cuyamaca reservoir, diversion and storage, p/34.
SAN DIEGO EIVER BASIN. 41

DISCHARGE MEASUREMENTS. Made from foot plank across flume at gage.

STORAGE AND DIVERSIONS. The Cuyamaca reservoir, on the headwaters of Boulder

Creek, has a capacity of 11,400 acre-feet. From the reservoir the water flows down

the natural channel of Boulder Creek and San Diego River to the intake of the

San Diego flume, a distance of 12J miles. Water is diverted into flume from

South Fork of San Diego River. 

ACCURACY. Rating curve fairly well defined. On account of leakage and diversion

for irrigation on the .Capitan Grande Indian Reservation, the record does not

show the total diversion. Results good. 

COOPERATION. Station maintained in cooperation with the Cuyamaca Water Co.,

through W. S. Posit, engineer.

Discharge measurements of San Diego flume near Lakeside, Cal., during the year

Sept. 30, 1913.

was built about 30 feet below gage.

DISCHARGE MEASUREMENTS. Made from cable at gage or by wading.

DIVERSIONS. Water is diverted fron Santa Ysabel Creek near the mouth of the canyon, 5 miles below the station, by East San Pasqual ditch, wjiich takes out on the 

left bank, and West San Pasqual ditch, which takes out on the right bank and 

below the intake of East San Pasqual ditch.

ACCURACY. Gage read three times daily, except at high stages, when it is read oftener; 

frequent discharge measurements are made, and results are good.

COOPERATION. Station maintained in cooperation with Volcan Land & Water Co., 

through W. S. Post, engineer.

EAST SAN PASQUAL DITCH NEAR ESCONDIDO, CAL.

LOCATION. In the NE. J sec. 36, T. 12 S., R. 1 W., at upper end of San Pasqual

Valley, about 9 miles, southeast of Escondido.

RECORDS AVAILABLE. June 9 to July 8,1912; October 1,1912, to September 30,1913. 

GAGE. Gage heights are determined by measuring distance to water surface from

reference point at top of flume.

CHANNEL. Considerable silt from Santa Ysabel Creek is deposited in the ditch. 

DISCHARGE MEASUREMENTS. Made from foot plank across flume at gage. 

ACCURACY. Daily discharges for 1913 computed by indirect method for shifting

channels. No estimates have been prepared for 1912, as sufficient discharge

measurements were not made to determine the changes in the channel. Results

fair. 

COOPERATION. Maintained in cooperation with Volcan Land'& Water Co., through

W. S. Post, engineer.

The intake of East San Pasqual ditch is on the left bank of Santa Ysabel Creek near 

the mouth of the canyon. From August 15 to January 15 this ditch is entitled to the 

entire flow of the stream. During the remainder of the year it has a right to divert 

16 second-feet for 10 consecutive days out of each 30.

SAN LUIS EEY RIVER NEAR PALA, CAL.

LOCATION. In the NW. J sec. 31, T. 9 S., R. 1W., above ford on road to Sickler's mill, 

about 4 miles southeast of Pala.

RECORDS AVAILABLE. October 9, 1903, to June 30, 1911, and November 14, 1912, to 

September 30,1913.'

DRAINAGE AREA. 322 square miles, revised estimate; area measured on military 

survey and United States Geological Survey topographic maps.

GAGE. Friez water-stage recorder on left bank 600 feet above ford. There is a staff 

gage in three sections at the same site. Previous to September 19,1912, gage was 

located about 50 feet above ford. Original datum has not been maintained.

CHANNEL. Sand, gravel, and bowlders; shifting. On September 19, 1912, an artificial control, consisting of short concrete cut-off walls between the bowlders, was 

built across channel just below gage.

DISCHARGE MEASUREMENTS. Made from cable 550 feet below recording gage or by 

wading.

DIVERSIONS AND STORAGE. Water is diverted for irrigation on the Rincon Indian 

Reservation. The Escondido Mutual Water Co. diverts water from San Luis Rey 

River about 10 miles above the station. This water, which is stored at the Escondido Reservoir, about 6 miles northeast of Escondido, is used for irrigation and 

municipal purposes at Escondido and vicinity. The capacity of the reservoir 

is 3,120 acre-feet. Water is diverted from Pauma Creek for irrigation on the 

Pauma Indian Reservation and Pauma Rancho.

ACCURACY. Rating curve is fairly well defined; results are excellent.

Discharge measurements of San Luis Rey River near Pala, Cal., during the period Sept. 20t

86 SURFACE WATER SUPPLY, 1913, PAST XI.

LYTLE CREEK NEAR SAN BERNARDINO, CAL.

LOCATION. In the NW. \ sec. 25, T. 2 N., R. 6 W., at Southern California Edison Co.'a 

diversion dam, below junction of North and Middle forka of Lytle Creek, in 

Angeles National Forest, about 3 miles above mouth of canyon, and 14 miles 

northwest of San Bernardino.

RECORDS AVAILABLE. September 18, 1904, to September 30, 1913.

DRAINAGE AREA. Not measured.

GAGE. Watson water-stage recorder in pool above weir in power canal.

DISCHARGE. Computed by combining flow in power canal with flow over diverting 

dam. Discharge of power canal is measured near the intake by an S-foo't steel 

plate rectangular weir. Flow over diverting dam is estimated, and no record ia 

furnished when total estimated discharge exceeds 80 second-feet.

ACCURACY. Daily discharge is mean of observations recorded each day at 6 a. m. and 

6 p. m. When total flow of Lytle Creek is diverted into power canal the resulta 

are good; above 23 second-feet (capacity of canal) they are approximate.

COOPERATION. Estimates of daily discharge are furnished by the Southern California 

Edison Co., through H. W. Dennis, construction engineer.

Daily discharge, in second-feet, of Lytle Creek, San Bernardino, Cal.,for the year ending

Sept. 30, 1913.

SUBFACE WATER SUPPLY, 1913, PABT XI. 115 

KERN AND TTTLARE LAKE BASINS. 

TULAEE LAKE IF KINGS COUNTY, CAL.

Tulare Lake is about 30 miles directly south of Fresno and 40 miles northwest of 

Bakersfield. The lake is roughly rectangular in shape and its greatest length is from 

northwest to southeast. In November, 1907, when its margin was carefully determined, the lake had an area of about 274 square miles, a maximum depth of 12.4 feet, 

an average length of 20 miles, and a width of 13.5 miles; the water's edge was 3 miles 

from the town of Corcoran, and the water surface about 12 feet below. The lake surface reached its greatest height in the summer of 1907, when it had a maximum depth 

of nearly 14 feet. Since July, 1907, it has been gradually subsiding.

The lake bed' resembles a flat saucer. The flat, level area in the bottom has an 

elevation of approximately 180 feet above mean sea level and covers about 55 square 

miles. The lowest point on the crest of the delta ridge to the north is about ,27 feet 

higher than the bottom of the lake. Natural overflow will not occur, therefore, until 

the lake has a maximum depth of nearly 30 feet and an area of nearly 1,000 square miles.

During 1906 and a part of 1907 a record of the stage of the lake was obtained neajf 

the entrance of Kings Eiver near Lemoore, Cal., at the middle of sec. 4, T. 21 S., 

E. 20 E. The zero of the gage was at an elevation of 175.1 feet above mean sea level, 

or 4 feet below the bottom of the lake (elevation 179.1 feet). May 11, 1907, a staff 

gage was set near Corcoran, Cal., referred to the same datum and used until July 30, 

1909.

July 28, 1910, a vertical staff gage in two sections was installed on the section line 

just south of the corner to sees. 27, 28, 33, and 34, T. 20 S., R. 2p E., about 10 miles 

south of Lemoore near Stratford post office. The datum of this gage is 171 feet above 

sea level. August 20, 1913, a vertical staff in four sections was installed at same 

datum, in main north and south waterway 4 to 6 miles southeast of Stratford. Sections No. 1 and No. 2 are 1 mile south of 1910 gage, in sec. 3, T. 21 S\., E. 20 E. No. 3 

is in sec. 10 and No. 4 is in sec. 15, 1 and 2~miles, respectively, south of sections No. 

, land No. 2.

The following summary1 gives a brief history of the fluctuations of the lake surface 

since 1853: 

1853. High.

1853-1,861. Subsidence; elevation of surface in 1861, 204 feet above sea level. 

1861-1863. Rapid rise to the highest known stage, 220 feet above sea level, overflowing

into San Joaquin Eiver; area about 800 square miles. 

1863-1867. Decline to about 208 or 209 feet above sea level. 

1867-1868. Filled again to about 220 feet above sea level. 

1872-1876. Fluctuated between 211 and 217 feet above sea level. 

1876-1883. Decline to 192 feet above sea level; lowest stage then known. 

1883-1897. Fluctuating; generally low.

1897-1905. Decline; practically dry in 1898; dry in autumn of 1905. 

1905-^1907. Eise; elevation of water surface in summer of 1907,193 feet above sea level;

area of water surface, November, 1907, 274 square miles.

1907-1908. Depth gradually decreased from 14 feet in June, 1907, to 8.3 feet in December, 1908. 

1909-1911. Gradual rise to depth of 13.4 feet in July, 1909; change in stage gradual to

December, 1911, when depth was 10 feet. 

1912-1913. Precipitation low. Depth gradually decreased to 1.5 feet in September, 

1913.

134 SUEFACE WATER SUPPLY,, 1913,, PART XI.

TULE RIVER NEAR PORTERSVILLE, CAL.

LOCATION. In the NW. i NW. £ sec. 25, T. 21 S., R. 28 E., below Mghway bridge 

near the McFarland ranch, about 1 mile above mouth of South Fork, and 6 miles 

east of Portersville. The North and Middle forks of Tule River unite about 9 

miles above the station.

RECORDS AVAILABLE. May 1, 1901, to September 30, 1913.

DRAINAE AREA. 266 square miles.

GAGE. Prior to December 6, 1912, staff in two sections on right bank, 100 feet below 

bridge; vertical upper section nailed to willow tree; inclined low-water section 

fastened to posts. Gage was checked and repaired December 6, 1912, and now 

consists of one inclined and three vertical sections.

CHANNEL. Gravel and small bowlders; practically permanent.

DISCHARGE MEASUREMENTS. Made from bridge above gage or by wading.

DIVERSION. Several small irrigation ditches divert water above the station.

ACCURACY. Sometime between September 15 and December 6, 1912, a tree was 

felled across river for foot-log. This -caused backwater at gage as shown by measurement on December 6. The tree was probably removed by the rise in February 

25, 1913. Results for remainder of year are good.

NOTE. Monthly and yearly discharge computed by engineers of the U. S. Geological Survey. 

CRANE VALLEY RESERVOIR NEAR NORTH FORE, CAL.

Crane Valley reservoir was formed by constructing a dam on North Fork Creek 

in the E. J sec. 26, T. 7 S., R. 22 E. The released water flows down the natural 

channel of North Fork Creek to a point just above the mouth of South Fork Creek, 

where it is diverted into the power canal.

Records show the total flow into the reservoir, including that of South Fork ditch, 1 

which diverts water from South Fork Creek about one-fourth mile below the mouth 

of Browns Creek.

Records from April, 1910, furnished by San Joaquin Light & Power Corporation.

Daily discharge, in second-feet, into Crane Valley reservoir near North Fork, Col., for

the year ending Sept. SO, 1913.

NOTE. 'Monthly and yearly discharge computed by engineers of the U.S. Geological Survey. 

TUOLUMNE RIVER NEAR GROVELAND, CAL.

LOCATION. In the SW. | sec. 24, T. 1 S., R. 17 E., 1 mile below junction with South 

Fork of Tuolumne River, and about 9 miles east of Groveland.

RECORDS AVAILABLE. September 2, 1907, to September 30,1913, (Not complete.)

DRAINAGE AREA. Not measured.

GAGE. Gurley electric water-stage recorder on left bank installed January 1,1913. A 

staff in two sections is fastened to rock ledge just above intake pipe of gage well. 

The Yosemite Power Co. has a Leitz water-stage recorder at pool about one-third 

mile above gage of United States Geological Survey, a short distance above a 

vertical staff, which is in two sections, on left bank. Leitz recorder was installed 

in August, 1910.

CHANNEL. Bowlders and solid rock; probably permanent.

DISCHARGE MEASUREMENTS. Made from cable one-third mile abfcve gage, near 

Yosemite Power Co.'s cable.

DIVERSIONS. See South Fork of Tuolumne River near Groveland.

ACCURACY. Rating curve well defined and results excellent for periods covered by 

gage-height record from January 1, 1913. Records September 2, 1907, to December 31, 1912, are from Yosemite Power Co.'s gage; discharge for this period has 

been computed from a rating curve, developed from the rating curve for the 

United States Geological Survey gage by means of a fairly well defined relation 

curve for the two gages. It has been assumed that no change in channel occurred.

COOPERATION. Gage-height record, September 2, 1907, to November 16, 1912, furnished by Yosemite Power Co., through H. A. Kluegel, chief engineer.

TUOLTTMNE RIVER NEAR LA GRANGE, CAL.

LOCATION. In the NE. \ SE. \ sec. 17, T. 3 S., R. 14 E., at La Grange dam, about 

\\ miles northeast of La Grange.

RECORDS AVAILABLE. August 30, 1895, to September 30, 1913.

DRAINAGE AREA. 1,500 square miles.

GAGE. Painted on rock ledge on right bank 80 feet above dam. Zero of gage is at 

average elevation of crest of dam.

DISCHARGE. Computed by means of weir formula from gage heights showing depth 

of water on crest of curved masonry diversion dam. Coefficient determined 

from current-meter measurements- made at highway bridge at La Grange, corrected to give discharge at dam. To obtain the total flow of Tuolumne River 

above La Grange dam, it is necessary to combine the flow over the dam with 

the discharge of Modesto, Turlock, and Yosemite Power Co.'s canals.
202 SUBFACE WATEE SUPPLY, 1913, PAET XI.

DIVERSIONS. Modesto and Turlock canals divert at dam. Yosemite Power Co.'e 

canal heads 13 iniles above the dam and the water is returned to the river below 

the dam and about half a mile above the bridge at La Grange. There is also 

a diversion from South Fork Tuolumne River at Harden ranch; water not 

returned to the river.

ACCURACY. Results good except at extremely low water. The combined record of 

river and canals is affected by seepage through dam and from canals, by the 

use of dashboards on the dam for a short period during the low-water flow, by 

the small amount of water occasionally spilled from canals at the waste gates 

above gaging stations, and by the water discharged through the ports and sandgates in the dam during parts of the year.

Daily gage height, in feet, of Tuolumne River near La Grange, Cal., for the year ending

Sept. 30, 1913.

The Yosemite Power Co.'s canal takes water from the south side of Tuolumne Kiver 

in the SW. J sec. 6, T: 2 S., R. 15 E., at Indian Bar, about 15 miles above the town of 

La Grange. This canal was built in the early days to supply water for hydraulic mining in the vicinity of La Grange, and is now locally known as the La Grange mining 

ditch. Recently it has been thoroughly repaired and is now used as a supply canal 

for the new hydroelectric plant which was installed! in the latter part of 1907. The 

power house is about half a mile above the town of La Grange and is below the dam 

and headworks of the Turlock and Modesto irrigation canals.

228 SURFACE WATER SUPPLY j 1913, PART XI.

MODESTO CANAL NEAR LA ORANGE, CAL.

LOCATION. In the SE. J sec. 17, T. 3 S., E. 14 E., near intake at La Grange dam, on 

right bank of Tuolumne River, about 1J miles northeast of La Grange.

RECORDS AVAILABLE. April 26, 1903, to September 30, 1913.

GAGE. Vertical iron staff in concrete well on left bank, 460 feet below head gates 

and below waste gates.

DISCHARGE MEASUREMENTS. Made from footbridge 550 feet below gage. This sec-' 

tion of the canal is lined with concrete.

ACCURACY. Rating curve fairly well defined; results good, Discharge measurements 

made during 1913 show that there-is slightly less discharge for same gage' height 

than in previous years. This appears to be catised by the accumulation of rock 

debris in the deep cut below gaging section. Above this point the rock, which 

slides into the canal during the rainy season, is occasionally removed.

Discharge 'measurements of Modesto canal near La Grange, Cal., during the, year ending

Sept. SO, 1913.

NOTE. Monthly and yearly discharge computed by engineers of the U. S. Geological Survey. 

STANISLAUS RIVER AT KNIGHTS FERRY, CAL.

LOCATION. In the NE. J sec.'29, T. 1 S., R. 12 E., at Knights Ferry, about 25 miles 

below mouth of South Pork and 12 miles northeast of Oakdale.

RECORDS AVAILABLE. May 19, 1903, to September 30, 1913. From May 3, 1895, to 

February 16,*1901, a station was maintained one-half mile north of Oakdale.

DRAINAGE AREA. 935 square miles.

GAGE. Staff in five sections on right bank. Although several changes have been 

made in the gage, original datum has been maintained. Zero of gage is 157.53 

feet above sea level, United States Geological Survey datum.

CHANNEL. Small bowlders and gravel; slightly shifting at high stages.

DISCHARGE MEASUREMENTS. Made from cable 50 feet above gage, or by wading.

STORAGE AND DIVERSIONS. Ditches diverting water for use in mining are numerous 

above station. Water is also diverted from the South Fork into the Tuolumne 

Basin, and from the North Fork for use in the vicinity of Murphy and Angeles. 

Water is stored for power development at Relief reservoir, on Middle Fork of 

Stanislaus River. Goodwin dam, 4 miles above Knights Ferry, was completed 

in December, 1912, by the South San Joaquin and Oakdale irrigation districts. 

Two canals, the South San Joaquin on the right bank and the Oakdale on the left 

bank, divert water at this dam for irrigation. No complete record of these diversions was obtained during the season of 1913. The Stanislaus and San Joaquin 

Water Co. 's canal was not in operation. .

ACCURACY. Results affected by the many diversions for irrigation and mining, and 

by the occasional operation of a power plant a short distance above the gage. 

Record considered good.

NOTE. No flow Dec. 3-5,1912, as water was being stored above new dam.

Observer recorded during July, 1913, that most of the water was in the canals and that at times during 

the day all of it was in the canals, as none ran over the dam. This condition probably was true for August 

and September.

DIVERSIONS. Douglas and Enterprise ditches, with a combined capacity of about 50 

second-feet, divert water from the Middle and South forks for power, domestic, 

and irrigation purposes at Plymouth and vicinity. Slug Gulch ditch, with a 

capacity of 7 or 8 second-feet, also diverts water from the Middle Fork when prior 

appropriations permit. Michigan Bar canal, which has a capacity of about 50 

second-feet, heads on the main Cosumnes at Musicdale Creek. No record is available showing the amount of water that is diverted.

ACCURACY. Conditions favorable for making good discharge measurements -at all 

stages; results are excellent.

SACRAMENTO RIVER NEAR RED BLUFF, CAL.

LOCATION. In lot 4, sec. 34, T. 28 N., R. 3 W., at the lower end of Iron Canyon, 4 

miles northeast of Red Bluff, and about 3 miles below the Iron Canyon dam site. 

Pain.es Creek enters about 3 miles above and Antelope Creek about 7 miles below 

the station.

RECORDS AVAILABLE. January 28,1902, to September 30,1913. The State engineer 

in 1879, and the commissioner of public works in 1893 and 1894 made measurements at this point. Prom April 30, 1895, to June 30, 1902, a gaging station was 

maintained at Jellys Ferry, 12 miles above Red Bluff.

DRAINAGE AREA. 10,400 square miles, including Goose Lake drainage area of 1,090 

square-miles.

GAGE. Staff in seven sections on the left bank. Several gages have been used at 

this station, but all observations have been reduced to the present datum.

CHANNEL. Coarse gravel and small bowlders; practically permanent.

DISCHARGE MEASUREMENTS. Made from a cable 50 feet above the gage.

DIVERSIONS AND STORAGE. No storage of importance has been developed in the 

drainage area above the station. With the exception of a small quantity of 

water diverted for irrigation from some of the minor tributaries, the record at this 

station gives the natural run-off from the basin.

ACCURACY. Rating curve well defined except during extremely high water; results 

excellent.

Sept. 30, 1913.

PIT RIVER AND TRIBUTARIES. 

PIT RIVER AT HENDERSON, CAL.

LOCATION. In sec. 36, T. 37 N., E. 1 W., at Big Bend Ferry, one-fourth mile above

Henderson. Nelson Creek'enters half a mile above and Kosk Creek 1 mile below

station.

RECORDS AVAILABLE. September 28, 1910, to September 30, 1913. 

DRAINAGE AREA. Not measured. 

GAGE. Vertical staff on alder tree on left bank about 100 feet above ferry. December

28, 1912, a Gurley electric water-stage recorder was installed 50 feet below staff

gage. Original datum maintained. Gages do not read the same owing to slope of

water surface between the two points. 

CHANNEL. Bowlders and coarse gravel; fairly permanent. 

DISCHARGE MEASUREMENTS. Made from cable 80 feet below gage. A standard car

and cable were installed in July, 1913, 25 feet below recording gage. 

ACCURACY. Eating curve fairly well defined; results good since December, 1912,

when water stage recorder was installed. Gage heights reported previous to that

date, uncertain.

CHANNEL. Gravel; somewhat shifting; at highest stages overflows into a second

channel.

DISCHARGE MEASUREMENTS. Made from a wagon bridge near the gage or by wading. 

WINTER FLOW. Winters are severe but the flow is so small during period when ice

is present that very little error is introduced-in the total estimates. 

REGULATION. Since the latter part of 1912 the reservoir of the Lakeview Irrigation

& Power Co., just above the station, has been operated. Storage prior to that

time was insufficient to materially affect the flow. 

ACCURACY. Records subject to considerable error on account of diurnal fluctuation.

Present conditions favorable for good results. 

COOPERATION. Gage-height record furnished by Lakeview Irrigation & Power Co.

270 SURFACE WATER SUPPLY, 1913, PART XI.

COTTONWOOD CREEK NEAR LAKEVIEW, OREG.

LOCATION. In the SW. J sec. 29, T. 38 S., R. 19 E., about one-half mile below a

proposed storage reservoir, 10 miles northwest of Lakeview." 

RECORDS AVAILABLE. November 22, 1908, to September 30, 1913. 

DRAINAGE AREA. 30 square miles. 

GAGE. Vertical staff installed March 23,1912; from November 22,1908, to January 18,

1909, a gage just above a weir one-fourth mile below the dam site was used;

January 19,1909, to March 22,1912, inclined staff at present location. 

CHANNEL. Clean gravel; fairly permanent; 10-foot weir November 22,1908, to January

16, 1909; 15-foot weir January 17 and 18, 1909. 

DISCHARGE MEASUREMENTS. Made from a footbridge 40 feet below present gage or by

wading. 

WINTER FLOW. Discharge relation at times affected by ice but flow during winter is

so small that no serious errors are introduced into the yearly estimates. 

DIVERSIONS. None above station. 

ACCURACY. Results fairly reliable but subject to some uncertainty in early spring

owing to large diurnal fluctuation when snow is melting. 

COOPERATION. Station maintained in cooperation with the Lakeview Irrigation &

Power Co., which furnishes gage-height record.

Discharge measurements of Cottonwood Creek near Lakeview, Oreg., for the year ending

Sept. 30, 1913.

NOTE. Creek covered with thick ice all winter. Apparently this was an ice roof caused by blocking 

of stream with anchor ice early in the morning and gage readings, made usually in the afternoon when 

the anchor ice had melted, were not affected.

LOCATION. In sec. 31, T. 37 N., R. 5 E., at highway bridge at Fall River Mills,

discontinued.

DRAINAGE AREA. Not measured.

GAGE. Vertical staff fastened to downstream end of left abutment of bridge.

SACRAMENTO RIVER BASIN". 277

HAT CREEK AT HAWKINS RANCH, NEAR HAT CREEK, CAL.

LOCATION. In sec. 5, T. 33 N., R. 5 E., at Hawkins ranch, 6 miles south, of Hat Creek.

RECORDS AVAILABLE. August 15, 1911, to August 9, 1913, when station was discontinued.

DRAINAGE AREA. Not measured.

GAGE. Vertical staff on downstream end of right support of footbridge.

CHANNEL. Sand and gravel; fairly smooth and permanent.

DISCHARGE MEASUREMENTS. Made from footbridge or by wading.

DIVERSIONS. The only important diversion for irrigation above this station is the 

H. M. Wilcox ditch, which heads about one-half mile above the'gage. About 40 

second-feet is diverted by this canal at irregular intervals, as shown by the 

observer's notes. Near the source of the creek water is diverted into Bear Creek 

drainage for use in development of power.

ACCURACY. Range of stage small; rating curve fairly well defined. Results good.

LITTLE STONY CREEK NEAR LODOGA, CAL.

LOCATION. At East Park Reservoir, 3J miles northwest of Lodoga, and 4 miles above 

junction with Stony Creek.

RECORPS AVAILABLE. January 1, 1908, to September 30, 1913.

DRAINAGE AREA. 102 square miles.

GAGE. Beginning December 1, 1910, the record is from the gage at the dam. Gage 

used previous to that date was a short distance below the present site.

DISCHARGE. Computed from gage heights observed at the dam. Correction has been 

made for evaporation, which is determined from records obtained from an evaporation pan at the reservoir. When the flow is 10 second-feet or less, the discharge 

is computed from weir and current-meter measurements taken at the head of the 

reservoir about 3 miles above the dam.

ACCURACY. Considerable care is used in collecting these data and results should be 

good.

COOPERATION. Record furnished by United States Reclamation Service through 

A. N. Burch, project manager.

NOTE. Monthly and yearly discharge computed by engineers of the U. S. Geological Survey.

FEATHER EIVEE AND TEIBUTAEIES. 

NORTH FORK OF FEATHER RIVER NEAR PRATTVILLE, CAL.

LOCATION. 4,200 feet downstream from north boundary of sec. 28, T. 27 N., R. 8 E., 

below the Great Western Power Co.'s dam (under construction) at Big Meadows, 

about 5 miles southeast oi Prattville, and 4 miles above mouth of Butt Creek.

RECORDS AYAH-ABLE. June 13,1905, to September 30,1913.

DRAINAGE AREA. 506 square miles above dam site.
310 SUEFACE WATEE SUPPLY, 1913, PAET XI.

GAGE. Friez water-stage recorder installed on left bank 5 feet above vertical staff. 

Gage used June 13, 1905, to April 28, 1912, was 3,500 feet upstream from present 

gage and 1,300 feet upstream from that used April 29 to July 31,1912. Datum of 

gage, 4,232.32 feet above sea level (United States Geological Survey datum). 

Original datum has not been maintained.

DISCHARGE MEASUREMENTS. Made from cable at gage. The results of discharge 

measurements made at this station have, however, been discarded, as they proved 

unsatisfactory owing"to high velocity of current and roughness of channel, and the 

discharge for 1912-13 has been computed from a rating curve based on currentmeter measurements made in March, 1914, in flume 3,000 feet above the gage.

CHANNEL. Bowlders; fairly permanent.

ACCURACY. Rating curve well defined; results considered excellent.

COOPERATION. Station is maintained and complete data are furnished by Great 

Western Power Co., through L. P. Cornell, engineer.

FEATHER RIVER AT OROVELLE, CAL.

LOCATION. In sec. 8, T. 19 N., R. 4 E., at highway bridge at Oroville, 6 miles 

below junction of North and Middle forks, and 30 miles above the mouth of 

Yuba River.

RECORDS AVAILABLE. January 1, 1902, to September 30,1913.

DRAINAGE AREA. 3,640 square miles.

GAGE. United States Weather Bureau vertical staff gage in two sections on pier of 

highway bridge near right bank. In November, 1912, a Friez water-stage recorder 

was installed on right bank 200 feet below bridge at same datum as staff gage, 

and these records show that the minimum state for the day occurs about 7 a. m., 

the time at which the Weather Bureau observations are recorded. (See fig. 1.)

CHANNEL. Bowlders and gravel; somewhat shifting at high stages.

DISCHARGE MEASUREMENTS. Made from car and cable 1,000 feet above bridge. 

At extreme low water in 1912 measurements were made from a boat about 1,000 

feet below bridge.

ARTIFICIAL CONTROL. Operation of the Big Bend plant of the Great Western Power 

Co. causes considerable fluctuation in stage, especially at extreme low water.

ACCURACY. Rating curve well defined; results good. Results from water-stage 

recorder show that low-water discharge computed from the Weather Bureau gage 

readings is 10 to 15 per cent too low.

COOPERATION. Prior to installation of recording gage the gage-height record was 

furnished by United States Weather Bureau, through N. R. Taylor, local forecaster.

BUTT CREEK AT BUTTE VALLEY, CAL.

LOCATION. In Butte Valley, 100 feet below footbridge, 2 miles above junction with 

North. Fork of Feather River, 1,000 feet above intake to Great Western Power 

Co.'s diversion flume, about one-fourth mile south of Butte Valley post office.

RECORDS AVAILABLE. June 14, 1905, to September 30, 1913.

DRAINAGE AREA. 73 square miles at original station.

GAGE. Vertical staff on left bank, installed July 19, 1912, seven-eighths mile upstream from original vertical staff which was on right bank. Gage is not influenced 

by low diversion dam near flume intake for Great Western Power Co.'s plant.

DISCHARGE MEASUREMENTS. Made from footbridge at gage.

CHANNEL. Sand, gravel, and clay; appears permanent.

DIVERSION. Oro Light & Power C o. diverts water from Butt Creek, above the station,

336 SURFACE WATER SUPPLY, 1913, PART XI.

YTTBA RIVER NEAR SMARTSVILLE, CAL.

LOCATION. In sec. 22, T. 16 N., R. 6 E., at the Narrows, 1 mile north of Smartsville, 

1 mile below mouth of Deer Creek, 6J miles below mouth of South Fork, 7 miles 

above mouth of Dry Creek, and 18 miles above the junction with Feather River.

RECORDS AVAILABLE. June 2, 1903, to September 30, 1913.

DRAINAGE AREA. 1,220 square miles.

GAGE. Staff in three sections, bolted to solid rock on left bank. Because of gradual

1 erosion of channel datum of gage was lowered 10 feet August 1, 1906.

CHANNEL. Gravel and small bowlders; shifting. As the result of extensive hydraulic 

mining in the early days the channel has been filled with an enormous quantity 

of tailings. At the station the depth of mining debris is estimated to be more than 

80 feet.

DISCHARGE MEASUREMENTS. Made from cable at gage.

DIVERSIONS. Water is diverted for power and irrigation above the station. Several 

small glacial lakes near the headwaters of the South Fork of Yuba River are 

utilized as storage reservoirs. Part of this water is diverted into the Bear and 

American River drainage basins.

ACCURACY. Results, except at high stages, good. Conditions poor for making accurate 

discharge measurements at high stages, owing to shifting channel and torrential 

nature of stream.

Discharge measurements of Yuba River near Smartsville, Gal., during the year ending

Sept. 30, 1913.

NOTE. Discharge determined from three fairly well defined rating curves applicable as follows: Oct. 1 

to Mar. 17, Mar. 18 to Apr. 30, and May 1 to June 17. All water was diverted into canal Qct. 1-22 and 25- 

28, Jan. 10 and 11 and June 18 to Sept. 30. The water diverted into the canal Jan. 10 and 11 and on 

certain days in March and April was probably spilled out before it reached the canal gage, as the canal 

record shows no flow for those periods. Discharge interpolated Mar. 22 and 23 and Apr. 12 to 14.

BEAR RIVER AT VAN TRENT, CAL.

LOCATION. In the SE. i sec. 21, T. 14 N., R. 6 E., below highway bridge at McCourtney crossing, 1 mile northwest of Van Trent, and 8 miles northeast of

Wheatland.

RECORDS AVAILABLE. Octobers, 1904, to September 30,1913. 

DEAINAGE AREA. 263 square miles.

GAGE. Staff in five sections on left bank 500 feet below bridge. 

CHANNEL. Solid rock, bowlders, and gravel. Shifts slightly at high water. 

DISCHARGE MEASUREMENTS. Made by wading or from cable half a mile below gage;

cable installed June 26, 1913. 

DIVERSIONS AND STORAGE. Water is diverted above station for power and irrigation.

A small amount of storage is developed on headwaters of stream. Stored water

from South Fork of Yuba River is diverted into this drainage basin above the

station near Colfax. 

ACCURACY. Results good at medium and low stages. Estimates for high water are

approximate, as rating curve is not well denned.

374 SURFACE WATEE SUPPLY,, 1913,, PART XI.

CACHE CREEK AT LOWER LAKE, CAL.

LOCATION. In the SE. J SE. i sec. 34, T. 13 N., R. 7 W., above highway bridge near 

outlet of Clear Lake, about 750 feet above mouth of Seigler Creek and 1 mile 

north of Lower Lake.

RECORDS AVAILABLE. January 1, 1901, to September 30, 1913.

DRAINAGE AREA. 500 square miles.

GAGE. Vertical staff on left bank 800 feet above bridge.

CHANNEL. Gravel; fairly permanent.

DISCHARGE MEASUREMENTS. Made from bridge or by wading. Flow of Seigler 

Creek is deducted when measurements afe made from bridge.

ACCURACY. At high stages Seigler Creek deposits gravel at its junction with Cache 

Creek and forms a small bar that sometimes affects discharge relation. At low 

water the channel is sometimes deepened in order to increase the flow from the 

lake. This was done about the middle of September, 1912. The measurement 

made December 11,1912, shows the amount of change. On account of the change 

in channel at low water and uncertainty of rating curve at high water results are 

only fair at those stages.

Sept. 30, 1913.

EAST FORK OF RUSSIAN RIVER NEAR UKIAH, CAL.

LOCATION. At suspension footbridge in Yokayo grant, about three-fourths mile above 

and 3 miles northeast of Ukiah.

RECORDS AVAILABLE. August 19, 1911, to September 30, 1913, when station was 

discontinued.

DRAINAGE AREA. Not measured.

GAGE. Staff in two sections on left bank, 40 feet below footbridge.

CHANNEL. Sand and gravel; shifts during high stages.

DISCHARGE MEASUREMENTS. Made from footbridge or private highway bridge above 

gage or by wading.

DIVERSIONS. The Snow Mountain Water & Power Co. diverts water by a tunnel 

from South Eel River for use in development of power at Potter Valley. This 

water enters the East Fork about 14 miles above station. At low stages regulation 

at power plant causes a noticeable fluctuation in the discharge; low-water record 

is therefore subject to some error, as only two gage readings are reported daily.

ACCURACY. Rating curves fairly, well defined except for high water; results fair.

Discharge measurements of East Fork of Russian River near Ukiah, Cal., during the year 

» ending Sept. SO, 1913.

EEL BIVEE AT TWO EIVEES, CAL.1

LOCATION. In the SW.J sec. 31, T. 22 N., R. 13 W., at highway bridge at Two Elvers,2

on Laytonville-Covelo road, and about 500 feet below junction of South and

Middle Eel rivers. Burger Creek enters about 1 mile below the station. 

RECORDS AVAILABLE. November 15, 1911, to September 30, 1913. 

DRAINAGE AREA. Not measured.

GAGE. Inclined staff in three sections on right bank at bridge. 

CHANNEL. Solid rock and coarse gravel; fairly permanent. 

DISCHARGE MEASUREMENTS. Made from cable three-fourths mile below gage, from

bridge, or by wading. 

DIVERSIONS. Snow Mountain Water & Power Co. diverts water from the South Eel

above Hearst to the East Fork of Russian River for use in development of power

at Potter Valley. 

ACCURACT. Rating curves well denned below gage height of 18 feet; results good.

Estimates above that stage approximate, but cover only a very short period.

Discharge for periods when gage was not read, estimated by comparison of record

at this station with that of Middle Eel River near Covelo.

1 Originally called Eel Eiver near Laytonville.

8 Northwestern Pacific Railroad station is Dos Bios.

VAN DUZEN RIVER AT BRIDGEVILLE, CAL.

LOCATION. In the SS. i sec. 11, T. 1 N., R. 3 E., just below highway bridge, at

Bridgeville. 

RECORDS AVAILABLE. September 22, 1911, to August 10, 1913, when station was

discontinued.

DRAINAGE AREA. 194 square miles. 

GAGE. Staff in three sections on right bank at bridge. 

CHANNEL. Gravel; somewhat shifting during high water. 

DISCHARGE MEASUREMENTS. Made from cable 90 feet below gage or by wading. 

ACCURACY. On account of frequent changes in channel caused by high water several

fairly well denned rating curves have been used. Estimates for high water are

approximate; other results fair.

NOTE. Daily discharge determined from rating curves applicable as follows: Oct. 1 to Dec. 15, 1912, 

well defined below 250 second-feet (same as used May 6 to Sept. 30,1912); Dec. 16,1912, to Jan. 18, 1913, 

poorly defined; Jan. 19 to Apr. 4,1913, fairly well defined below 500 second-feet; Apr. 5 to June 30, 1913, 

fairly well defined below 250 second-feet. Discharge estimated July 1 to Sept. 30, 1913, by interpolation 

between discharge measurements. High-water estimates are based on extension and parallelism of rating 

curves, and are only approximate. Discharge Nov. 6 to Dec. 15,1912. somewhat uncertain owing to lack 

of measurements between rises.

UPPER KLAMATH LAKE NEAR KLAMATH FALLS, OREG.

LOCATION. In sec. 30, T. 38 S., R. 9 E., at the outlet of Upper Klamath Lake about

2 miles northwest of Klamath Falls. 

RECORDS AVAILABLE. May 28 to October 22,1904; January 7, 1906, to September 30,

1913. 

GAGE. Friez water-stage recorder since February 16, 1906, vertical staff prior to that

date. Zero is 4,136.13 feet above sea level. 

ACCURACY. Gage heights are very much affected by the wind. The water is lowered

as much as 6 inches near the outlet when the wind blows from the south, and is

raised as much above its normal level when the wind is in the opposite direction.

There is a periodic oscillation when the wind blows for any length of time. 

COOPERATION. Since May, 1909, this station has been maintained by the United

States Reclamation Service.

NOTE. Lake was frozen December to March.

LINK RIVER AT KLAMATH FALLS, OREG.

LOCATION. In sec. 32, T. 38 S., R. 9 E., near foot of rapids between Upper Klamath 

Lake and Lake Ewanna, at Klamath Falls.

RECORDS AVAILABLE. May 15,1904, to September 30,1913.

GAGE. Since September 14, 1912, Friez water-stage recorder referred to vertical 

staff on left bank above lowest rapids. Original gage was a vertical staff at 

highway bridge; read to April 2, 1908; replaced by a chain gage which was read 

to September 7, 1912. From June 6,1908, to August 31, 1912, the Friez recorder 

was located on right bank above present site and at different datum.

CHANNEL. Probably permanent.

DISCHARGE MEASUREMENTS. Made at county bridge about 500 yards below gage.

WINTER FLOW. Discharge relation seldom affected by ice.

DIVERSIONS. The Keno Canal diverts water from right bank of river above gage for 

use in Moore Bros.' power plant. Water returned to the river below gage but 

above measuring section. The amount of the diversion is practically constant 

at about 200 second-feet, and the record has been computed as if it passed the

ACCURACY. Results good since Friez recorder was moved in September, 1912.

Earlier records somewhat uncertain. 1 

COOPERATION. Field data furnished by U. S. Reclamation Service.

1 See McOlashan, H. P., and Stevens, G. C., Surface water supply of the United States, 1912, Part 11, 

Pacific coast basins in California: U. S. UeoL Survey Water-Supply Paper 331, p. 365,1914.

KLAMATH RIVER AT KENO, OREG.

LOCATION. In sec. 31, T. 39 S., R. 8 E., at the county bridge at Keno.

RECORDS AVAILABLE. May 31, 1904, to December 31, 1913, when station was discontinued.

DRAINAGE AREA. 3,150 square miles (excluding Lower Klamath Lake drainage area).

GAGE. Vertical staff nailed to bridge. Datum has not been changed since the 

station was established.

CHANNEL. Sand and clay; fairly permanent. Immediately below station the river 

breaks over a rocky ledge with a fall of about 200 feet to the mile.

DISCHARGE MEASUREMENTS. Made from cable about 1,000 feet below gage.

DIVERSIONS. A large quantity of water is diverted for irrigation above the station. 

There is a considerable loss by evaporation from the lakes.

ACCURACY. During low water the accuracy of the record is somewhat affected by 

the growth of aquatic plants. Discharge relation is also affected by wind. 

Results considered good for periods of a week or more, but for individual days 

somewhat uncertain. Rating curve used 1906-1913 has been checked by 

measurements made at Spencer Bridge in 1915 and referred to the datum of the 

Keno gage.

COOPERATION. Field data furnished by United States Reclamation Service.

MILLER CREEK NEAR CRESCENT, OREG.

LOCATION. In sec. 2, T. 28 S., R. 7 E., about 4 miles above the Knott ranch and

about 20 miles south of Crescent. 

RECORDS AVAILABLE. November 14, 193.1, to December 31, 1912; August 17 to

September 30, 1913. 

DRAINAGE AREA. Not measured. 

GAGE. Vertical staff; read not more than once a week. 

CHANNEL. Sand and gravel; somewhat shifting. 

DISCHARGE MEASUREMENTS. Made by wading or from foot-logs. 

COOPERATION. Station maintained in cooperation with the Hunter Land Co.

The water sinks completely a few miles below the gage, and it is probable that there 

is some underflow at the station. Miscellaneous measurements May 12, 1912, show 

about 2 second-feet more water 3 miles above the gage than at the gage and about 11 

second-feet more water at the gage than 4 miles below. For this reason a better place 

for the gage can not be found.

Estimates can not be made for the period October to December, 1912.

The following discharge measurement was made by James E. Stewart:

August 17,1913: Gage height, 1.11 feet; discharge, 14.3 second-feet.

Daily gage height, in feet, of Miller Creek near Crescent, Oreg., for the year ending Sept.

30, 1913.

NOTE. All readings refer to datum of water stage recorder but on account of the small fluctuation and 

lack of sensitiveness of the gage, only the observer's readings have been used, except those taken during 

the spring flood. Gage heights undoubtedly affected by ice about Dec. 17 to Feb. 27 as no increase in 

discharge could be expected at the extremely high elevation (about 5^800 feet) during the winter. Gage 

readings Mar. 25, raised by snow jams; old gage read 0.90 foot.

450 SUEEACE WATEE SUPPLY, 1913, PAET XI.

TULE LAKE NEAE MEEBILL, OEEG.

LOCATION. In sec. 8, T. 41 S., R. 11 E., at J. F. Adams's ranch, near the mouth of

Lost River, 3 miles east of Merrill, Klamath County. 

RECORDS AVAILABLE. May 17, 1904, to September 30, 1913. 

GAGE. Vertical staff fastened to boathouse on shore of lake since July 26,1912. Zero

of the gage is at elevation 4,050 feet. A vertical staff on a post driven in the lake

bed had been used previously. The elevation of its zero as determined from the

best available information has been as follows:

Feet.

May 17, 1904.............. 4,047. 73

Oct. 21, 1904.............. 4,047. 76

Feet.

May 11, 1907 ............ 4,048. 56

Nov. 27, 1908............. 1 4,048. 60

The gage readings have been published as reported and no attempt has been 

made to reduce them to a uniform datum. A graph of the gage heights has failed 

to reveal any critical points that would account for a sudden change. It is therefore likely that the gage was raised by the ice a little at a time during the winters 

of 1905-6 and 1906-7. For this reason the gage heights prior to May, 1907, should 

not be used for any refined studies.

COOPERATION. Since May, 1909, station has been maintained by United States 

Reclamation Service and records have been prepared for publication by the 

United States Geological Survey.

NOTE. Gage was cheeked Feb. 1 and found to have settled on account of knocking out of foundation 

pile from boathouse to which it was attached. Readings prior to that date have been discarded. Lake 

frozen from some date not recorded, probably in December, until about Apr. 12.

J Referred to the original bench mark installed in 1904. According to another bench mark it was a 

levation 4,048.4 feet.
KLAMATH ElVER BASIN. 451

MILLEK CKEEK NEAK LOEELLA, OKEG.

LOCATION. In sec. 7, T. 40 S., R. 14 E., at the site of an old wagon bridge about 

three-fourths mile above the highway bridge, a mile east of the Swingle ranch in 

Langell Valley, and 3 miles south of Lorella, Klamath County.

RECORDS AVAILABLE. April 1, 1909, to September 30, 1913. Records were kept 

August 10, 1904, to December, 1908, at a former station in sec. 12, T. 39 S., R. 

13 E., at the lower end of Horsefly Valley and 10 miles or more by creek above 

the present station; there is only a small amount of inflow between the two points.

GAGE. Friez water-stage recorder installed on left bank, attached to old bridge 

abutment.

CHANNEL. Stream bed, rocks, and gravel covered with some silt; control fairly 

permanent.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

WINTER FLOW. Discharge relation apparently not materially affected by ice, as 

control remains open; open-channel rating curve formerly applied throughout 

winter but no discharge has been computed for low stages in winter of 1913.

DIVERSIONS. A small irrigating flume carrying about 1 second-foot diverts just above 

the present station and there is probably a considerable area irrigated above the 

station.

REGULATION. Flow m'ay be occasionally affected by a rock and brush diversion dam 

just above gage.

ACCURACY. Results considered good for higher stages as the rating curve defined by 

measurements made in 1910-11 has been confirmed in 1915-16; for low and medium 

stages the rating is very uncertain and no estimates have been attempted except 

during the months of considerable run-off.

COOPERATION. Field data furnished by United States Reclamation Service.

NOTE. Discharge determined from a rating curve well defined above 200 second-feet. Below 200 secondfeet it is based on measurements made in 1915 and 1916 and its applicability to gage heights taken in 1913 

is doubtful. July 13-16, discharge interpolated. The true discharge for the early part of March and May 

to July may be somewhat greater than the estimates given.

COFFEE CREEK AT COFFEE, CAL.

LOCATION. In the NW. \ sec. 4, T. 37 N., R. 8 W., in Shasta National Forest at 

private highway bridge at Coffee, and about 5 miles above junction with Trinity 

River. Boulder Creek enters 400 feet above and Little Boulder Creek 1£ miles 

below station.

RECORD AVAILABLE. December 16, 1910, to September 30, 1913.

DRAINAGE AREA. Not measured.

GAGE. Vertical staff fastened to upstream end of bridge pier near right bank.

CHANNEL. Gravel and bowlders; fairly permanent.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

WINTER FLOW. Discharge relation sometimes slightly affected by ice during December 

and January.

REGULATION. From April to July, inclusive r and occasionally throughout rest of 

year, two dams with automatic or " self -shooting" gates are operated about 10 

miles above station. The Nash mine operates a dam having a working capacity 

. of about 125 acre-feet; the Holland mine, on the East Fork, a dam having a 

working capacity of about 40 acre-feet. At the beginning of the season, in April, 

these dams fill and "shoot" about once an hour; at the end of the season, in July, 

once in 20 or 24 hours. During high water these "floods" are hardly perceptible, 

but late in the season their effect is pronounced. An effort is made to secure 

gage readings when the flow is normal.

ACCURACY. The gage-height record, on account of the operation of these dams, is 

subject to some error; otherwise results good.

COOPERATION. Station maintained in cooperation with United States Forest Service.

SOUTH FORK OF TRINITY RIVER NEAR CHINA FLAT, CAL.

LOCATION. In sec. 17, T. 6 N., R. 5 E., at suspension footbridge, one-eighth mile 

above junction with Trinity River, and about 6 miles southeast of China Flat.

RECORDS AVAILABLE. October 12, 1911, to August 10, 1913, when station was discontinued.

DRAINAGE AREA. Not measured.

GAGE. Vertical staff in two sections bolted to rock ledge on right bank 30 feet above 

bridge.

CHANNEL. Bowlders and gravel; somewhat shifting.

DISCHARGE MEASUREMENTS. Made from bridge below gage or by wading.

ACCURACY. Trinity River at medium and high stages causes backwater at station, 

and discharge estimates have been prepared for thtse periods by correcting 

observed gage heights for backwater and applying fairly well defined rating curves 

developed for free-flow conditions. AH estimates except for low water subject 

to considerable error on account of uncertainty as to amount of backwater.

Discharge measurements of South Fork of Trinity River near China Flat, Cal., during 

the year ending Sept. 30, 1913.

NOTE. Discharge determined from rating curves applicable when backwater did not occur in the following periods: Oct. 12,1911, to May 1.1912, poorly defined; May 2 to Nov. 6,1912, poorly defined; Nov. 7, 

1912, to Sept. 13,1913, fairly well denned below 4,500 second-feet; high-water estimates are based on extension of the rating curves and are only approximate.

Discharge has been estimated for effect from backwater by comparison of records at this station with 

those for Trinity River near China Flat for the following periods: Jan. 8, 9, Jan. 25 to Feb. 28, Mar. 6 to 

Apr. 24, Apr. 29 to June 22, and June 24, Nov. 6-18, Dec. 15-22, Dec. 30.1912, to Jan. 2,1913, Jan. 15-22, 

Jan. 30 to Feb. 25, Mar. 6-24, Mar. 28 to June 25, June 27 and 28,1913. Estimates are based on meager data 

and involve several assumptions, and estimates should be used with caution.

NOTE. Daily discharge determined from rating curves applicable as follows: Sept. 8, 1911, to Feb. 17, 

1912, and Feb. 18 to May 1.1912 (chain gage readings) from two poorly defined rating curves; May 2,1912, 

to Jan. 18,1913 (chain gage) from rating curve fairly well defined below 3,000 second-feet; Jan. 19 to Sept. 30, 

1913 (chain gage readings), from curve fairly well defined below 3,000 second-feet: June 1 to Sept. 30,1913 

(staff gage readings), from well defined curve. Discharge for days for which gage height was not recorded, 

estimated, so far as feasible, by comparison of record with that of North Fork of Smith River near Crescent 

City. High-water estimates are based on extension of rating curves and are only approximate.
