SURFACE WATER SUPPLY OF THE PACIFIC COAST Ef 

CALIFORNIA, 1912.

By H. D. MCGLASHAN and G. C. STEVENS.

AUTHORIZATION AND SCOPE OF 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 

the year October 1, 1911, to September 30, 1912.

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 gfcruc- 

'ture, mineral resources, and products of the national domain.

The work was begun in 1888 in 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 year ending June 30 

1895................................................... $12,500

1896................................................... 20,000

1897 to 1900, inclusive................................... 50,000

1901 to 1902, inclusive................................... 100,000

1903 to 1906, inclusive................................... 200,000

1907................................................... 150,000

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 (a) furnishing data or (ft) by assisting in 

collecting the data. Acknowledgments for cooperation under class 

"a" are made in connection with the description of each station 

affected, and for class "b" on page 18.

Measurements of stream flow have been made at about 2,000 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. During 1912 gaging stations were maintained by the Survey 

and the cooperating organizations at about 1,500 points, and many 

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.

For each calendar year there has been prepared a report embodying 

the stream-flow 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. Circulars are also available 

giving complete lists of the gaging stations maintained by the Survey 

to date, and a list of the reports relating to the water supply of the 

country.

Prior to 1902 gage heights and discharge measurements were published in water-supply papers or bulletins and estimates of monthly 

discharge in annual reports; since 1902 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:

a For the purpose of uniformity in the presentation of reports, a general plan has been agreed won by 

the United States Reclamation Service, the United States Forest Service, the United States Weather 

Bureau, and the United States Geological Survey, according to which the area of the United States has 

been divided into 12 parts, whose boundaries coincide with natural drainage lines indicated by the parts 

of the report.

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

The table which follows gives, by years and drainage basins, the 

numbers of the papers on surface water supply published from 1899 

to 1911. 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 by Part I are 

published in Water-Supply Papers 97, 124, 165, 201, 241, 261, 281, 

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

from 1903 to 1912. The year covered by the report is indicated at 

the head of the column in which the paper is listed.

DEFINITION OF 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 second-feet 

per square mile, and (2) those which represent the actual quantity 

of water, as run-off in depth in inches, and acre-feet. The units used 

in this series of reports are second-feet, second-feet per square mile, 

run-off in depth in inches, and acre-feet. They may be defined as 

follows:

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

the unit for the rate of discharge of water flowing in a stream 1 foot 

wide, 1 foot deep, at a rate of 1 foot a second. It is generally used 

as a fundamental unit from which others are computed by the use of 

the factors given in the following table of equivalents.
14 SURFACE WATER SUPPLY, 1912, PART XI.

"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.

CONVENIENT EQUIVALENTS.

EXPLANATION OF DATA.

For each regular current-meter gaging station the following data, 

so far as available, are given: Description of the station, list of discharge measurements, table of daily gage heights, table of daily 

discharge, table of monthly and yearly discharges 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 installation 

of current-meter stations, the descriptions give information in regard
16 SURFACE WATER SUPPLY, 1912, PART XI.

to any conditions which may affect the constancy of the relation of 

gage height to discharge, 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 and reliability of the data.

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. The gage 

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

the water above the zero of the gage. All gage heights affected by 

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

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 flow, so that negative 

readings shall not occur.

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 gives^ the discharge in second-feet 

corresponding to the observed gage heights as determined from the 

rating tables.

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 13 and 14, are based.

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

description of station, have been collected by the methods commonly 

used at current-meter gaging stations and described in standard text 

books.

the work. Plate II shows types of automatic gages.

ACCURACY AND RELIABILITY OF FIELD DATA AND 

COMPARATIVE RESULTS.

The accuracy of stream-flow data depends primarily on the natural 

conditions at the gaging station and on the methods and care with 

which the data are collected. Errors of the first group depend on 

the degree of permanency of channel and of permanency of the relation between discharge and stage.

Errors of the second class are due, first, to errors in observation of 

stage; second, to errors in measurements of flow; and, third, to errors 

due to misinterpretation of stage and flow 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 

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

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

"fairly well defined," within 10 per cent; "poorly defined" $r "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 maximum or minimum nor to any individual day, but 

to the monthly mean. It is based on the accuracy of the rating, the 

probable reliability of the observer, 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 

run-off in inches may be subject to gross errors which result from 

including in the measured drainage area large noncontributing dis- 

. tricts or omitting estimates of water diverted for irrigation or other 

use, and they should therefore be considered as only approximate 

particularly for periods of irrigation or of low water. For these 

errors it is as a rule not feasible to make adequate correction.

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

any engineer the means of examining and adjusting to his own needs 

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 

29950° WSP 331 14 2
18 SURFACE WATER SUPPLY, 1912, PART XI.

should not be used for other than preliminary estimates. The 

determinations of daily discharge allow more detailed studies of the 

variation in flow by which the period of deficiency may be determined. 

It should be borne in mind that the observations in each succeeding 

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

and published, and the engineer who makes use of the figures presented in these papers should verify all ratings and make such 

adjustments for earlier years as may seem, necessary.

COOPEBATION.

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 legislature, 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 Conservation Commission and the State Board of Control 

(Water Power) of the State of California, in September, 1911, arranged 

for cooperation with the United States Geological Survey. This 

agreement provides for a complete digest of all available data concerning the flow of the streams in the State of California; records of 

streams not hitherto investigated; surveys of the streams, showing 

slope, topography, and such other data as may be necessary to determine water power and storage possibilities along the streams.

The reports containing these data have been published by the 

Geological Survey as Water-Supply Papers 295-300, inclusive.

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.

In addition, many complete estimates of run-off, gage-height 

records, and discharge measurements are furnished by various Federal bureaus, private companies, and individuals who are interested in the water resources of California. This cooperation is 

acknowledged and explained in the separate station descriptions 

which precede the data.

DIVISION OF WORK.

The field work in California was carried on under the direction of 

H. D. McGlashan, district engineer, by E. O. Christiansen, F. C. 

Ebert, Lasley Lee, Charles Leidl, G. T. Peekema, R. C. Rice, J. E. 

Stewart, and H. J. Tompkins.
TIA JUANA EIVEE BASIN. 19

The ratings and special estimates were made by H. D. McGlashan, 

R. H. Bolster, R. C. Rice, G. C. Stevens, and C. L. Batchelder.

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

on under the direction of W. W. Patch, project engineer, United 

States Reclamation Service, and the field data furnished to the 

United States Geological Survey. The ratings and special estimates 

for the Oregon stations were made by F. F. Henshaw, E. S. Fuller, 

and G. C. Stevens.

The computations were made and the completed data prepared for 

publication under the direction of G. C. Stevens and C. L. Batchelder 

by H. D. Padgett, H. J. Dean, A. H. Tuttle, J. G. Mathers, W. R. 

King, C. F. Walker, M. I. Walters, and G. A. Wallace.

The entire report was edited by Mrs. B. D. Wood.

SOUTHERN PACIFIC OCEAN DRAINAGE BASINS.

TIA JUANA RIVER BASIN. 

COTTONWOOD CKEEK NEAR JAMUL,, CAL.

Location. At Barrett dam site, 6J miles below intake of Dulzura conduit, in the 

SW. i sec. 15, T. 17 S., R. 3 E., about 12 miles southeast of Jamul. Pine Valley 

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

Records available. December 15,1905, to September 30,1912.

Drainage area. Approximately 270 square miles.

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 1911 and 1912.

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 the flow is over the entire length of the dam, which is 61 feet. Measurements are made by wading, except at high stages, when only float velocities 

are 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 municipal 

purposes 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. The seepage loss between intake and measuring 

weir is estimated at about 3 per cent.

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

capacity of 46,000 acre-feet. During 1911,1,530 acre-feet were impounded in this 

reservoir, not 10,500 acre-feet as published in Water Supply Paper 311, page 19. 

On October 1,1912, there were 3,710 acre-feet impounded in the reservoir.

Accuracy. No discharge measurements were made during 1911 and 1912. The 

range of stage was small and results are considered good.
20 SURFACE WATER SUPPLY, 1912, PART XI.

Cooperation. Estimates of daily discharge for 1911 and 1912 furnished by Southern 

California Mountain Water Co. No daily gage heights were furnished, but daily 

discharge is said to have been determined from the rating curve developed by the 

United States Geological Survey.

BOULDER CREEK AT CUYAMACA RESERVOIR, NEAR LAKESIDE, CAL.

Location. At outlet of Cuyamaca reservoir, 12 miles above mouth of Boulder Creek 

and 22 miles northeast of Lakeside.

Records available. June 19 to September 30, 1912.

Drainage area. Not measured.

Gage. Vertical staff about 6 feet above weir; read three times each day.

Discharge measurements. Made by wading 100 feet below gage.

Diversions 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 1$: 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 12£ 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 Southern California Mountain Water Co.
28 SURFACE WATEB SUPPLY, 1912, PAET XI.

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 second-foot from this flume.

Accuracy. Rating curve is well defined and results are excellent.

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

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

BOULDER CREEK AT MOUTH, NEAR LAKESIDE, CAL.

Location. 300 feet above junction with San Diego River, in the NW. J sec. 12, 

T. 14, S., R. 2 E., about 14 miles northeast of Lakeside.

Records available. August 12 to September 30, 1912.

Drainage area. Not measured.

Gage. Vertical staff in pool about 8 feet above crest of weir.

Discharge. Computed from gage-height read three times each day, record showing depth of water over sharp-crested 6-foot weir without end contractions.

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 considered 

excellent.

Cooperation. Weir was installed and gage-height record furnished by Cuyamaca 

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

The following discharge measurement was made by F. C. Ebert, August 16,1912: 

Gage height, 0.53 foot; discharge, 7.3 second-feet.

Daily gage height, in feet, and discharge, in second-feet, of Boulder Creek at mouth, near

Lakeside, Gal, for 191%.

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

Location. At diverting dam in the SE. J sec. 11, T. 14 S., B. 2 E., about 14 miles

northeast of Lakeside.

Records available. May 4 to September 30, 1912. 

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

above sand box.

Discharge measurements. Made from foot plank across flume at gage. 

Accuracy. A well defined rating curve has been developed for period when there

was no head on intake gate. Measurements obtained on May 24 were made

under varying heads, after reservoir had been filled. Sufficient data are not

available for the preparation of estimates while water was stored in reservoir.

After May 31 it is believed that there was but little head, if any, on intake gate

and results are good. 

Cooperation. Maintained in cooperation with Cuyamaca Water Co., through W. S.

Post, engineer.

SAN DIEGO FLUME NEAR LAKESIDE, CAL.

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, 1912. 

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

Discharge measurements. Made in flume at reference point. 

Storage and diversions. The Guyamaca 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 Biver to the intake

of the San Diego flume, a distance of 12£ miles. 

Accuracy. Bating curve is fairly well defined. On account of leakage and diversion

for irrigation on the Capitan Grande Indian Beservation the record does not

show the total diversion. Besults are good. 

Cooperation. Maintained in cooperation with the Cuyamaca Water Co., through

W. S. Post, engineer.

SANTA ANA RIVER BASIN. 

SANTA ANA EIVEE NEAR MENTONE, CAL.

Location. Just above road crossing opposite Warm Springs Canyon, in the SW. J 

SW. J sec. 34, T. 1 N., R. 2 W., three-fourths of a mile below intake of Pacific 

Light & Power Co.'s canal, about 2 miles above the mouth of the canyon, and 5 

miles northeast of Mentone.

Records available. July 1, 1896, to September 30, 1912.

Drainage area. 182 square miles.

Gage. Vertical staff on right bank about 100 feet above ford. The present gage 

was installed February 25, 1910. Previous to this date various gages were used. 

The original datum has not been maintained.

Channel. Gravel and bowlders; will shift during high water.

Discharge measurements. The flood of January, 1910, destroyed the car and 

cable. This equipment has not been replaced, as it is difficult to reach the station 

at high water. Measurements are made by wading at medium and low stages.

Artificial control. Southern California Edison Co.'s power plants Nos. 1 and 2 

are located 5J and 2f miles, respectively, above the Mentone plant at the mouth 

of the canyon. The intake of the Pacific Light & Power Co..'s canal is at plant 

No. 2. The tailrace from this plant discharges into the canal. The Greenspot pipe line diverts water from the forebay at the Mentone power house. Water 

is stored on Bear Creek at Bear Valley reservoir.

Accuracy. Results are good.

MILL CREEK AT FOREST HOME, 1 CAL.

Location. At Forest Home, in the NW. \ NE £ sec. 13, T. 1 S., R. 1 W., about 2J 

miles below Falls Creek, 4 miles above Mountain Home Creek, and 14 miles east 

of Redlands.

Records available. September 23, 1903, to September 30, 1912.

1 Akers Camp on map of San Gorgonio quadrangle, U. 8. Geol. Survey.
SANTA ANA EIVER BASIN. 59

Drainage area. Not measured.

Discharge. Obtained by combining flow in power canal with flow over diverting

dam. The flow in the canal is determined by current meter measurements. The

flow over diverting dam is approximate and no report is made when total discharge

exceeds 100 second-feet. 

Accuracy. Daily discharge is mean of two observations recorded each day at 6 a. m.

and 6 p. m. When total flow of Mill Creek is diverted into power canal results

are good; at higher stages 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 Mill Creek at Forest Home, Cal., for 1911-12.

NOTE. Daily discharge determined from two fairly well defined rating curves applicable 1911 to Apr. 

11,1912, and Apr. 12 to Aug. 26,1912. Aug. 28 to Sept. 30,1912, discharge determined from a 30-inch Gippoletti weir. Discharge interpolated for days on which gage was not read except Dec. 9-31,1911, and Mar. 

5-9,1912, which was a flood period and for which no estimates have been made. Discharge values April 

to June supersede those published in Water-Supply Paper 300, p. 605.

LYTLE CREEK NEAR SAN BERNARDINO, CAL.

Location. At Southern California Edison Co.'s diversion dam in the NW. J sec. 25, 

T. 2 N., R. 6 W., below junction of North and Middle forks of Lytle Creek, in 

the 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, 1912.

Drainage area. Not measured.
64 SURFACE WATER SUPPLY, 1912, PART XI.

Gage. Watson water-stage register in pool above weir in power canal.

Discharge. Obtained by combining flow in power canal with flow over diverting 

dam. Discharge of power canal is measured, near the intake, by an 8-foot steel 

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

furnished when total estimated discharge exceeds 80 second-feet.

Accuracy^ Daily discharge is mean of two observations recorded each day at 6 a. m. 

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

results 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 near San Bernardino, Cal., for 1911-12.

SAN ANTONIO CREEK NEAR UPLAND, CAL.

Location. Below Pacific Light & Power Co.'s power house in SW. J sec. 36, T. 2 N., 

R. 8 W., about 4 miles above mouth of canyon and 8 miles northwest of Upland.

Records available. March 11, 1901, to September 30, 1912.

Drainage area. Not measured.

Discharge. From March 11, 1901, to August 24, 1907, station was located above 

intake of power canal, which is 1 mile above power house. Later records are 

computed from gage-height record obtained at 10-foot rectangular weir in tail 

race. The excess water flowing over diverting dam is estimated.

Accuracy. The capacity of power canal is about 21 second-feet. When flow of 

stream does not exceed this amount the results should be excellent.

Cooperation. Records furnished by Pacific Light & Power Co., through G. O. Newman, chief engineer.

Daily discharge, in second-feet, of San Antonio Creek near Upland, Cal., for 1901-1912.

N., R. 10 W., about one-fourth mile above Pacific Light & Power Co.'s power

house and 2 miles north of Azusa. 

Records available. 1894 to September 30, 1912. 

Drainage area. 222 square miles. 

Gage. Staff in five sections, beneath cable, just above ford; three vertical sections

on posts in channel, one inclined and one vertical section bolted to rocks on left

bank.

Channel. Gravel and bowlders; will shift at high stages. 

Discharge measurements. Made from car and cable at gage or by wading.
74 SURFACE WATER SUPPLY, 1912, PART XI.

Diversions. The power canal of the Pacific Light & Power Co. heads about 5 mileg 

above the station. This water is not returned to the river. In addition there 

are a few small irrigation ditches that occasionally divert water above the station.

Accuracy. On account of change in channel, results are only fair.

Discharge measurements of San Gabriel River near Azusa, Gal., in 1912.

TULAKE LAKE IN 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 kept by means of 

a Government staff gage located near the entrance of Kings River near Lemoore, Cal., 

at the middle of sec. 4, T. 21 S., R. 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). On May 11, 1907, a staff gage was set near Corcoran, Cal., referred to the 

same datum and used until July 30, 1909.

On 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. 20 E., about 10 

miles south of Lemoore near Stratford post office. Th6 datum of this gage is 171 

feet above sea level.

All published gage records have been reduced to show the actual depth of the 

water on the lowest point of the lake bed.

Daily gage height, in feet, of Tulare Lake in Kings County, Cal., for 1911-12.

SOUTH FORK OF KERN RIVER NEAR ONYX, CAL.

Location. Three-fourths of a mile north of the Kernville-Walker Pass road, on 

the Eankin ranch, in the NE. \ SW. i sec. 24, T. 25 S., R. 35 E., and about 5 

miles northeast of Onyx.

Records available. September 12, 1911, to September 30, 1912.

Drainage area. Not measured.

Gage. rlnclined staff on left bank 200 feet below intake of lower Rankin ditch, 

installed November 16, 1911, at about the same site and with same datum as 

temporary vertical staff previously used. The vertical gage, which is fastened 

to an inclined stump, has been gradually rising since new gage was installed. 

Hence gage-height record September 12 to November 11, 1911, is doubtless in 

error.
122 SURFACE WATER SUPPLY, 1912, PART XI.

Channel. Sand and fine gravel; fairly permanent.

Discharge measurements. Made from car and cable 60 feet below gage or by

wading.

Diversions. Three small irrigation ditches head above the station. 

Accuracy. Rating curve fairly well defined and results are fair.

182 SURFACE WATER SUPPLY, 1912, PART XI.

TUOLUMNE RIVER NEAR LAGRANGE, CAL.

Location. At Lagrange dam, in the NE. J SE. J sec. 17, T. 3 S., R. 14 E., about 1$ 

miles northeast of Lagrange.

Records available. August 30, 1895, to September 30, 1912.

Drainage area. 1,500 square miles.

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

average elevation of crest of dam. Previous to April 1,1908, gage was located at 

highway bridge at Lagrange.

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

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

from current meter measurements made at highway bridge, about 2 miles below 

the dam, cdrrected to give discharge at dam. To ascertain the total flow of 

Tuolumne River at Lagrange, add the flow over the dam to the discharge of 

Modesto, Turlock, and Yosemite Power Co.'e canals.

Diversions. Modesto and Turlock canals divert at dam. Yosemite Power Co.'s 

canal heads 13 miles above the dam. The water from the power canal is returned to the river below the dam and about half a mile above the bridge. 

There is also a diversion from South Fork Tuolumne River at Hardin ranch, for 

power purposes, that is not returned to the river.

Accuracy. Results are excellent except at extreme low water. The combined 

record of river and canals is slightly affected by seepage from dam and canals 

and by the small amount of water that is occasionally spilled from canals at the 

waste gates above the gages.

Daily gage height, in feet, of Tuolumne River near Lagrange, Gal., for 1911-12.

YOSEMITE POWER CO.'s CANAL1 NEAR LAGRANGE, CAL.

Location. At the flume opposite Lagrange dam, about 1 mile above power house

and 1J milea northeast of Lagrange.

Records available. 1908 to September 30,1912 (not complete). 

Gage. Depth of water in flume is measured at reference point.

1 Formerly known as Lagrange Water & Power Co. canal.
SAF JOAQUIN EIVEE BASIN. 189

Discharge measurements. Made in flume near point at which gage heights are

observed.

Accuracy. Results are good. 

Cooperation. Gage-height record furnished by Turlock irrigation district through

Burton Smith, chief engineer.

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

River at Indian Bar, about 15 miles above the town of Lagrange. This canal 

was built in the early days to supply water for hydraulic mining in the vicinity of 

Lagrange, and is now locally known as the "Lagrange 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 later part of 1907. The power house is 

situated on the bank of the river about three-quarters of a mile above the town of 

Lagrange and is below the dam and headworks of the Turlock and Modesto irrigation 

canals.

STANISLAUS EIVEE AT KNIGHTS FEEEY, CAL.

Location. -At Knights Ferry, in the NE. I sec. 29, T. 1 S., R. 12 E., about 25 miles 

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

Records available. May 19, 1903, to September 30, 1912. 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 four vertical and one inclined. The 

original gage datum has been maintained, although several changes have been 

made in the gage. 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 car and cable 40 feet above gage or by 

wading.

Storage and diversions. Ditches diverting water for use in mining are numerous 

above the 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. 

The intake of the Stanislaus & San Joaquin Water Co.'s canal is about 3 miles 

above Knights Ferry. This canal returns water below the station. Schell 

ditch diverts about 6 second-feet from this canal above the gaging station on the 

canal. Considerable storage is developed on Middle Fork of Stanislaus River 

for use in power development.

Accuracy. Results are affected by the many diversions for irrigation and mining 

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

is considered good except at flood stage. 

The total natural flow of the river at this point is determined by combining the

discharge at the river gaging station with the discharge of Stanislaus & San Joaquin

Water Co.'s canal and SchelPs ditch.

SACRAMENTO RIVER BASIN. 

SACRAMENTO RIVER AT CASTELLA, CAL.

Location. At the private highway bridge at Castella, in sec. 22, T. 38 N., R. 4 W., 

about half a mile below the mouth of Castle Creek.

Records available. October 15, 1910, to September 30, 1912.

Drainage area. 257 square miles.

Gage. Vertical staff on downstream end of bridge pier near right bank.

Channel. Small bowlders; fairly permanent.

Discharge measurements. Made from bridge one-half mile below gage. This 

section is more satisfactory than the one at the highway bridge where early measurements were made.

Accuracy. Results are good at low stages. The high-water rating curve is not 

well denned and results are only fair.

Cooperation. Gage-height record furnished by H. O. Wickes.

Discharge measurements of Sacramento River at Castella, Gal., in 1912.

SACRAMENTO RIVER NEAR RED BLUFF, CAL.

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

4 miles above Red Bluff and about 3 miles below the proposed Iron Canyon 

dam site. Paines Creek enters about 3 miles above and Antelope Creek about 

7 miles below the station.

Records available. January 28, 1902, to September 30, 1912. The State engineer 

in 1879 and the commissioner of public works in 1893 and 1894 made measurements at this point. From 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 several 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 car and cable 50 feet above the gage.

Diversions and storage. No storage of any importance has been developed in 

the drainage area above this station. A small amount of water is diverted from 

some of the minor tributaries for irrigation. With this exception the record at 

this station gives the natural run-off from the basin.

Accuracy. Results at this station are excellent.

The following discharge measurement was made by Lasley Lee: 

July 19,1912: Gage height, 1.61 feet; discharge, 5,730 second-feet.
230 SURFACE WATER SUPPLY, 1912, PART XI.

Daily gage height, in feet, of Sacramento River near Red Bluff, Cal.,for 1911-12.

DREWS CREEK NEAR LAKEVIEW, OREG.

Location. In sec. 4, T. 40 S., R. 18 E., 1 mile below the Drews Creek dam, 13

miles southwest of Lakeview.

Becords available. January 16, 1909, to September 30, 1912. 

Drainage area. 211 square miles. 

Gage. A Friez automatic gage, installed March 19,1912, to replace Barr-ett-Lawrence

gage, which was put in place of the original vertical staff in December, 1911. 

Channel. Gravel; not likely to shift; at highest stages overflows into a second

channel. 

Discharge measurements. Made from a wagon bridge near the gage and by

wading. 

Winter flow. Winters are severe at this station but the flow is so small during the

ice period that very little error is introduced in the total estimates. 

Diversions and artificial control. The flow has been partly controlled during

th» spring of 1912 by operations at the dam under construction above the gage.

The irrigation canal which will divert water past the gage is not yet completed

and no water has yet been diverted, although some water has been stored. 

Accuracy. Before installing the automatic gage the records were subject to considerable error on account of diurnal fluctuation. The present conditions are

favorable for good results. 

Cooperation. This station is maintained by the Lakeview Irrigation & Power Co.,

which furnishes the records to the Survey.

Location. In sec. 29, T. 38 S., R. 19 E., at a dam site 10 miles northwest of Lakeview.

Records available. November 22, 1908, to September 30,1912.

Drainage area. 30 square miles.

Gage. Since March 23, 1912, a vertical staff has been used. Prior to that time an

inclined staff in the same location had been used. 

Channel. Clean gravel; fairly permanent. 

Discharge measurements. Made from a footbridge 40 feet below the present gage.

At low stages made by wading near the gage. 

Winter flow. Gage heights are at times affected by ice, but the flow during the

winter period is so small that no serious errors are introduced into the estimates. 

Diversions. There are at present no diversions above the station. 

Accuracy. Conditions are excellent at this station and the results obtained are

reliable. 

Cooperation. Station is maintained in cooperation with the Lakeview Irrigation <fe

Power Co., which furnishes the gage-height record.

THOMAS CREEK NEAR LAKE VIEW. OREG.

Location. In sec. 22, T. 38 S., B. 19 E., about 8 miles below the proposed Thomas 

Creek reservoir, and about 10 miles northwest of Lakeview.

Records available. January 1,1912, to September 30, 1912.

Drainage area. Not measured.

Gage. Vertical staff. The gage installed January 1 was found to be in the influence 

of backwater from a dam, so a new vertical staff was installed March 9,1912, 300 

feet above the old one and was set to read same as old gage.

Channel. Sand, gravel, and yellow clay; evidently shifting.

Discharge measurements. Made by wading at all but highest stages when measurements may be made from the highway bridge at the gage.

Accuracy. Owing to the shifting nature of the channel it will be difficult to get 

accurate results at this station. The six measurements referred to the old gage 

are scattering and no curve is defined. Only two measurements have been 

referred to new gage, therefore no estimates have been made.

Cooperation. This station is maintained in cooperation with the Lakeview Irrigation & Power Co.

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

Location. At Hawkins ranch, in sec. 5, T. 33 N., R. 5 E., .6 milea south of Hat 

Creek.

Records available. August 15, 1911, to September 30, 1912.

Drainage area. Not measured.

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

Channel. Fairly smooth and probably permanent.

Discharge measurements. Made from footbridge.

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 power development.

Estimates are withheld until additional measurements are secured.

HAT CREEK AT EAT CREEK, CAL.

Location. At private highway bridge on Morris ranch, in the Lassen National Forest, 

in the SE. i sec. 10, T. 34 N., R. 4 E., M. D. M., 1 mile north of Hat Creek post 

office. 1

Records available. September 22,1910, to September 30,1912.

Drainage area. Not measured.

Gage. Vertical staff fastened to downstream end of right abutment of bridge.

Channel. Gravel and small bowlders; apparently permanent.

Discharge measurements. Made from downstream side of bridge.

Diversions. On account of the diversions for irrigation above the station this record 

does not show the natural run-off from the drainage basin. On May 13,1911, the 

nine ditches were diverting a total of 110 second-feet. Of this amount, it was 

estimated that 55 second-feet was returned to the stream above the gage.

Accuracy. Eating curve fairly well defined; results fair.

Cooperation. Gage-height record furnished by United States Forest Service.

Jan. 1 to Sept. 30,1912, well defined. Discharge estimated Apr. 24-30,1912, from flow of adjacent streams, 

and precipitation records. Discharge interpolated for all other days on which gage was not read; results 

are therefore only roughly approximate and should be used with caution.

UTTLE COW CREEK AT PALO CEDRO, CAL.

Location. At highway bridge, in see. 5, T. 31 N., R. 3 W., one-fourth mile east of

Palo Cedro and one-fourth mile above junction with Cow Creek. 

Records available. August 9, 1911, to September 30, 1912. _ 

Drainage area. Not measured. 

Gage. Vertical staff on bridge pier near right bank. 

Channel. Gravel and small bowlders; may shift slightly at high stages.
SACRAMENTO RIVER BASIN. 263

Discharge measurements. From bridge, except at low stages, when measurements are made by wading above the gage.

Diversions. A small amount of water is pumped from this stream for irrigation. 

The Terry Lumber Co.'s flume, which is supplied by a diversion from Montgomery Creek, discharges into this stream. From June to December this amounts 

to 8 or 10 second-feet. For the remainder of the year this is reduced to about 

6 second-feet.

Accuracy. Rating curve fairly well defined; results fair.

BEAR CREEK NEAR MILLVILLE, CAL.

Location. At highway bridge, in sec. 36, T. 31 N., R. 3 W., 4 miles southeast of

Millville and 5 miles above junction with Sacramento River. 

Records available. August 19, 1911, to September 30, 1912. 

Drainage area. Not measured.

Gage. Vertical staff in two sections on upstream side of bridge pier near left bank. 

Channel. Small bowlders; rough.
SACRAMENTO RIVER BASIN. 265

Discharge measurements. Made by wading about 50 feet above the gage, except 

at high Btages, when measurements are made from the bridge.

Diversions. A small amount of water is diverted into this drainage basin from the 

headwaters of Hat Creek, and is used for power development.

Accuracy. Record is not very reliable, as control is subject to changes due to the 

temporary rock dam below the bridge.

Discharge measurements of Bear Creek near Millwlle, Cal., in 1912.

NOTE. On Nov. 9,1911 a bowlder dam was constructed across the channel below the gage. This raised 

the water surface from 1 foot to 1.75 feet. Parts of this dam have been washed out during various highwater stages, affecting the relation of discharge to gage height.

NOTE. Daily discharge determined from two fairly well defined rating curves applicable as follows: 1911 

and Jan. 1 to Sept. 30,1912. During 1911 discharge was interpolated for days when gage was not read, and 

therefore these values are only approximate. Discharge values from Jan. 1 to June 30,1912, supersede 

those published in Water-Supply Paper 298, p. 158.

LITTLE STONY CREEK NEAR LODOGA, CAL.

Location. At East Park reservoir, 4 miles above junction with Stony Creek and

3J miles northwest of Lodoga.

Records available. January 1, 1908, to September 30, 1912. 

Drainage area. 102 square miles. 

Gage. Previous to December 1, 1910, the station was maintained a short distance

below the present site. Several gages with independent datums were used.

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

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. 

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.

Daily gage height, in feet, of Little Stony Creek near Lodoga, Cal.,for 1911.

276 SURFACE WATER SUPPLY, 1912, PART XI.

Gage. Friez water-stage register, located on left bank, 5 feet above auxiliary vertical staff gage. Automatic gage installed at present location July 31, 1912. 

Prior to this date, gage was located at dam site 1 mile upstream. From September 20, 1911, to April 29, 1912, it was located 500 feet above dam site. From 

April 29 to July 31, 1911, it was located a short distance downstream from former 

location. The construction work on the dam necessitated making these changes. 

The Friez gage was used at all three locations. The original datum has not been 

maintained. Gage is located between two riffles with considerable fall above 

and below.

Discharge measurements. Made from car and cable at staff gage.

Channel. Bowlders; fairly permanent.

Accuracy. Measurements affected by roughness of stream bed and high velocities 

at medium and high stages. Results are considered excellent by company.

Cooperation. Station is maintained and complete data furnished by Great Western 

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

The Great Western Power Co. is constructing a dam at Big Meadows which, when 

completed, will be 150 feet high, with a'storage capacity of about 1,280,000 acre-feet. 

The reservoir will have a surface area of about 44 square miles. Power for construction purposes is generated at the power plant on Butt Creek. 

The following discharge measurement was made from cable by Lasley Lee: 

Sept. 23, 1912: Gage height, 1.68 feet; discharge, 560 second-feet.

Daily discharge, in second-feet, of North Fork of Feather River near Prattville, Cal.,fw

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

highway bridge near right bank. This gage was read from 1902 to 1905. In 

December, 1905, a gage was installed on the left bank at the cable, about 1,000
SACRAMENTO BIVEE BASIN. 281

feet upstream from the bridge. Gage heights for 1906-1910 were referred to this 

gage. The Weather Bureau gage was read during 1911 and 1912. In November, 

1912, a Friez water-stage register was installed. These records show that the 

minimum stage for the day occurs at about 7 a. m., the time at which the Weather 

. Bureau observations are recorded.

Channel. 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.

Accuracy. Rating curve is well defined and results are good. Daily discharges at 

low water, computed from the Weather Bureau record, are about 10 per cent low.

Cooperation. Gage-height record furnished by United States Weather Bureau, 

through N. R. Taylor, local forecaster.

BUTT CREEK AT BUTTE VALLEY, CAL.

Location. At lower end of Butte Valley, 100 feet below footbridge, 2 miles above 

junction with North Fork of Feather River, 1,000 feet above the intake to the 

Great Western Power Co.'s diversion flume, and about one-fourth mile south of 

Butte Valley post office.

Records available. June 14, 1905, to September 30, 1912.

Drainage area. 73 square miles at original station.
SACRAMENTO RIVER BASIN. 283

Gage. A vertical staff on left bank, installed July 19, 1912, seven-eighths of a mile 

upstream from original vertical staff which was on right bank; the new gage is 

out of the influence of a newly completed low diversion dam near the flume intake 

for the Great Western Power Co.'s Butt Creek plant.

Discharge measurements. Made from footbridge at gage.

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

Diversions. Water is diverted from Butt Creek above the station into Yellow Creek 

watershed through Wallack ditch by the Oro Light & Power Co. The ditch has 

a capacity of from 15 to 20 second-feet. Pending litigation with the Great Western Power Co., only a small amount of water is diverted. From July 5 to 15? 

1912, about 15 second-feet were diverted. There are no other diversions above 

the station.

Cooperation. Station maintained and complete data furnished by Great Western 

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

NOTE. Monthly values computed by engineers of United States Geological Survey. 

INDIAN CREEK NEAR CRESCENT MILLS, CAL.

Location. At the lower end of Indian Valley, in the SW. J eec. 25, T. 26 N., R. 9 E., 

about 2,000 feet below Arlington Bridge and 1J miles below Crescent Milk. Spanish Creek enters 4 miles below the station.

Records available. January 1, 1906, to December 31, 1909, and September 10,

1911. to September 30, 1912. 

Drainage area. 740 square miles.

Gage. Vertical staff in three sections on right bank near observer's house. 

Channel. Fairly permanent. At low stages water is deep and sluggish at gage. 

Discharge measurements. Made from Arlington Bridge or by wading during

1912. Impossible to make measurements from the bridge at flood.stages. The 

car and cable, which were destroyed by the flood of 1907, were replaced, about 30 

feet below the gage, in September, 1912.

Diversions. Water is diverted from Indian Creek for irrigation in Indian and Genesee 

valleys.

Estimates are withheld until additional measurements are available.

NOTE. On Jan. 29, 30, 31; Feb. 1, 2.12,15; and Mar. 18,19, 27, and 28, the water was turned out of the 

canal during a portion of the day, which accounts for the low mean gage height. On Apr. 10 and May 20 

the observer noted: "Water turned out on account of heavy rain."

YUBA RIVER NEAR SMARTSVILLE, CAL.

Location. At The Narrows, in sec. 22, T. 16 N., R. 6 E., 1 mile north of Smartsville 

and 18 miles above the junction with Feather River, 6£ miles below mouth of 

South Fork, 1 mile below mouth of Deer Creek, 7 miles above mouth of Dry 

Creek.

Becords available. June 2, 1903, to September 30,-1912.

Drainage area. 1,220 square miles.

Gage. Staff in three sections, bolted to solid rock on left bank. On account of the 

gradual erosion of the channel the gage datum was lowered 10 feet on August 1, 

1906.

Channel. Gravel and small bowlders, and is shifting. As the result of extensive 

placer 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 more than 80 

feet.

Discharge measurements. Made from car and cable at gage.

Diversions and storage. Water is diverted for power and irrigation above the 

station. Several small glacial lakes near the headwaters of the South Fork of 

Yuba are utilized as storage reservoirs. A part of this water is^ diverted into the 

Bear and American river drainage basins.

Accuracy. Conditions for obtaining accurate discharge data at high stages are poor, 

owing to the shifting of the channel and the torrential nature of the stream. 

Results at low and medium stages are good; at high water they should be considered approximate.

SACRAMENTO RIVER BASIN. 309

BEAR RIVER NEAR COLFAX, CAL.

Location. At Pacific Gas & Electric Co.'s diversion dam in sec. 22, T. 15 N., R. 9

E.,. about half a mile below mouth of Greenhorn River and 3 miles north of Colfax. 

Records available. November 1, 1911, to September 30, 1912. 

Drainage area. Not measured. 

Gage. A vertical staff in three sections, on the left bank, 50 feet above the dam,

installed January 1, 1912, to replace the gage which was installed October 20,

1911, on left bank, about 500 feet above the dam, and was read during November

and December, 1911. The records from this gage give only the flow over the

dam.

Channel. Gravel; will shift. 

Discharge measurements. Made from car and cable 500 feet above dam or by

wading. 

Diversions and storage. A small amount of storage has been developed above the

station. Some stored water from South Fork of Yuba River is diverted into

this drainage above the station. 

Accuracy. Rating curve is fairly well defined and results are good. Discharge of

Pacific Gas & Electric Co.'s canal must be added to obtain total flow of river. 

Cooperation. Gage-height record furnished by Pacific Gas & Electric Co., through

James H. Wise, assistant general manager.

Discharge measurements of Bear River and Pacific Gas & Electric Co.'s power canal near

Colfax, Cal., in 1911-12.

Diversions and storage. Water is diverted above station for power and irrigation.

A small amount of storage is developed on the headwaters of this stream. Some

stored water from South Fork of Yuba River is diverted into this drainage above

the Colfax station. 

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

are approximate, as rating curve is not well denned.

AMERICAN RIVER AT FAIROAKS, CAL.

Location. At highway bridge, 1,500 feet northwest of Southern Pacific Co.'a railroad 

station at Fairoaks Bridge and half a mile southeast of Fairoaks.

Records available. November 3, 1904, to September 30, 1912.

Drainage area. 1,910 square miles.

Gage. Painted on right abutment of bridge near downstream end, with a vertical 

staff for low water. The position of the gage has been changed several timee 

since the station waa established, but no change has been made in its datum,
318 SURFACE WATER SUPPLY, 1912, PART XI.

Channel. Gravel and small bowlders; shifts slightly at high water.

Discharge measurements. Made from downstream side of bridge and by wading.

Diversions. Water is diverted and stored for power and irrigation above the station.

Accuracy. Readings made by a new observer October 1 to December 31, 1911, 

are about 2 feet too high as compared with gage heights at Folsom and estimates of discharge at Placerville, Colfax, and East Auburn, and accordingly 

are not published. The rating curves developed for 1911 and 1912 are good. 

The mean discharge October, November, and December, 1911, is the combined 

discharge of North Fork of American River near Colfax, Middle Fork of American 

River near East Auburn, and South Fork of American River near Placerville, 

plus an assumed inflow of 20 to 30 second-feet.

The intake of this canal is on Gerle Creek about If miles above the mouth; the 

course of the ditch is south until it crosses the Little Rubicon. It then flows down 

the valley to a point in the main Rubicon canyon, where it is carried by a tunnel 

into the Pilot Creek drainage area, a total distance of about 10 miles.

The South Fork ditch is used from June to November for conveying the stored 

water from Loon Lake to Pilot Creek, where the water is diverted into a ditch and 

used for irrigation on Georgetown divide. The ditch serves as a reservoir supply to 

Pilot Creek and is used only when Pilot Creek flow is not sufficient to supply the 

demand.

Daily discharge, in second-feet, of Little South Fork ditch at sawmill near Quintette, Cal.,

Creek is deducted when measurements are made from bridge.

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

Creek. This results in a small bar which somewhat affects the control. At low 

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

lake. This happened 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.

PUTAB CREEK AT WINTERS, CAL.

Location. Just below Southern Pacific Co.'s railroad bridge at Winters, in the Rio

de los Putos grant.

Records available. September 26,1905, to September 30, 1912. 

Drainage area.j 805 square miles. 

Gage. Staff in five sections on left bank, 600 feet below bridge. An auxiliary

vertical staff on right bank is used for low water. The original gage datum has

been maintained.
SACRAMENTO RIVER BASIN. 337

Channel. Sand and gravel and somewhat shifting. Two channels at low water. 

Discharge measurements. Made from car and cable at gage or by wading. 

Diversions. With the exception of a small amount of water pumped for irrigation,

there are no diversions above the station. 

Accuracy. On May 13, 1912, a temporary dam was constructed 500 feet below the

station. This produced ponded water at the gage. From June 10 to September

11,1912, a temporary gage, fastened to the downstream side of the dam was read.

Discharge estimated May 13 to June 9, 1912. Results are fair.

EAST FORK OF RUSSIAN RIVER NEAR UKIAH, CAL.

Location. At suspension footbridge in the Yokayo grant, about three-fourths mile 

above junction with Russian River and 3 miles northeast of Ukiah.

Records available. August 19, 1911, to September 30, 1912.

Drainage area. Not measured.

Gage. Staff in two sections on left bank, 40 feet below bridge.

Channel. Sand and gravel; shifts during high stages.

Discharge measurements. Made from footbridge above gage or by wading.

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

the South Eel for use in power development at Potter Valley. This water enters 

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

power plant causes a noticeable fluctuation in the discharge. On this account 

the low-water record is subject to some error, as only two gage readings are reported 

each day.

Accuracy. Rating curves are fairly well defined and results are fair.

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 milea northwest of Klamath Falls.

Records available. May 28, 1904, to September 30, 1912.

Gage. A Friez automatic register.

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. 

The staff gage to which the automatic gage is referred was in poor condition during 

1911, and as a result the 1911 record is subject to much uncertainty. The gage 

was repaired late in 1911, and the records obtained since that time are more reliable.

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

States Reclamation Service but the results have been worked up by the Survey.

NOTE. During 1911 the Friez automatic gage was not working well. The published values have been 

obtained by careful study of the gage sheets and comparison with readings on the staff gage. The breaks 

in the record were caused by the stopping of the automatic register or the loss of the record sheets. Lake 

probably frozen from Jan. 1 to about the middle of February, 1912.

LINK RIVER AT KLAMATH FALLS, OREG.

Location. In sec. 32, T. 38 S., R. 9 E., at the county bridge over Link River at 

Klamath Falls, 1J miles below the outlet of Upper Klamath Lake and immediately at the head of Lake Ewanna.

Records available. May 15, 1904, to Sept. 30, 1912.

Drainage area. 3,110 square miles.

Gage. Chain gage at bridge. Since June 6, 1908, a Friez automatic gage has also 

been maintained in the rapids above the bridge. The location of the Friez gage 

was changed September 5, 1912.

Channel. Fairly permanent at both gages; water swift at upper gage, sluggish at 

lower gage.

Discharge measurements. Made at the county bridge.

Winter flow. Gage height seldom if ever affected by ice.

Diversions. Since about Sept. 1, 1908, water has been diverted around the Friez 

gage in the Keno canal on the west side of the river. This water after being used 

in the Moore Bros, power plant, has been returned to the river between the Friez 

gage and the bridge. The measurements and records of the United States Reclamation Service have made possible a fairly accurate estimate of this diversion. 

It has been measured at times, and has been maintained fairly constant between 

changes. Some water has been wasted over a spillway just above the power 

flume, probably averaging not more than 5 second-feet. Water has also been 

diverted in the main canal of the Klamath project on the east Bide of the river. 

Monthly discharges for this canal are given on page 371.
KLAMATH RIVER BASIN. 365

Accuracy. The relation of gage height to.discharge at the bridge is seriously affected 

by wind, and the discharge varies so materially, owing to surging of Upper Klamath Lake, that reliable estimates can not be computed from readings on this 

gage. A detailed account of the difficulties encountered and of the methods used 

in attempting to overcome them is given in Water-Supply Paper 311. From 

June 6,1908, until some time during the summer of 1909 the records given by the 

Friez gage were reliable, but since that time on account of diversions, damage 

resulting from logs striking the gage well, backwater from logs, and failure to keep 

the gage always at proper datum, the records are subject to some uncertainty, but 

are still more reliable than can be secured from gage readings at the bridge.

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

States Reclamation Service, the Survey working up and publishing the data.

KLAMATH KIVEK AT KENO, OKEG.

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

Records available. May 31, 1904, to September 30, 1912.

Drainage area. 3,150 square miles (excluding Lower Klamath Lake drainage 

area).

Gage. Vertical staff nailed to bridge. The datum has not been changed since the 

station was established.

Channel. Sand and clay. Fairly permanent. A growth of aquatic plants accumulates during low water. Immediately below the station the river breaks over 

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

Discharge measurements. From standard cable and car about 1,000 feet below

Winter flow. River usually freezes over in winter, but as water is deep and the 

ice never very thick, gage-height records are not seriously affected.

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

the growth of weeds. Wind also has an effect at times. No measurements have 

been secured since 1909, and later estimates are somewhat uncertain.

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

States Reclamation Service.

KLAMATH RIVER NEAR HAPPY CAMP, CAL.

Location. At Evans Ferry, in the NW. J sec. 16, T. 16 N., R. 8 E., and about 4 

miles southeast of Happy Camp. Indian Creek enters 3£ miles below the station.

Records available. September 10,1911, to September 30, 1912.

Drainage area. Not measured.

Gage. Vertical staff in two sections on left bank. Low-water section is 60 feet and 

upper section 1,200 feet below ferry cable.

Channel. Bowlders and gravel; probably permanent.

Discharge measurements. Made from suspension bridge about 2,000 feet above

Diversions. Water is diverted from main river and tributaries above the station 

for use in irrigation, placer mining, and power development.

Accuracy. Rating curve is well defined for low and medium stages. Results, 

except at high stages, are good.

Mr. Gordon, at Evans Ferry, has kept a record of the maximum floods on Klamath 

River. These records, reduced to the datum of the United States Geological Survey 

gage, are as follows:

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, 1911, to September 30, 1912.

Drainage area. Not measured.

Gage. Vertical staff.

Charm el. Sand and gravel; probably permanent.

Discharge measurements. By wading and from foot logs.

Accuracy. Limited by the frequency of gage readings. At present it is impossible 

to secure more than one reading a week. The creek 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. On this account it is impossible to place the gage in a 

more accessible place than at present.

Cooperation. This station is maintained in cooperation with the Hunter Land Co.

KLAMATH EIVER BASIN. 381

SYCAN EIVER NEAR YAINAX, OREG.

Location. Sec. 3, T. 36 S., R. 12 E., at the house of David Chocktoot, 2J miles above

the junction of Sycan and Sprague rivers and about 13 miles above Yainax. 

Records available. November 25, 1911, to September 30, 1912. 

Drainage area. 527 square miles. 

Gage. Vertical staff.

Channel. Sand and gravel, somewhat shifting. 

Discharge measurements. Made from a standard car and cable about 3 miles

above the gage. 

Accuracy. On account of the shifting nature of the channel and the inaccessibility

of this station, it will be difficult to get accurate results. It may be necessary

later to move the gage up nearer the cable. 

Cooperation. This station is maintained in cooperation with the United States

Indian Service.

Estimates of daily and monthly discharge are withheld until additional data are 

secured.

FOURMILE CREEK NEAR ODESSA, OREG.

Location. In sec. 9, T. 36 S., R. 5 E., just below the outlet of Four Mile Lake,

about 15 miles northwest of Odessa. 

Records available. April 6,1912, to August 8,1912. 

Drainage area. Not measured. 

Gage. A vertical staff 10 feet below dam at outlet. 

Channel. Rocks and gravel; probably permanent. 

Discharge measurements. Made from a footbridge near the gage or by wading.
KLAMATH RIVER BASIN. 383

Artificial control. A dam has been built at the outlet of the lake and a gate for 

controlling the flow has been constructed. This gate has been kept open since 

the station has been maintained and therefore there has been no artificial control.

Accuracy. Fair results should be obtained at this point.

Cooperation. This station is maintained in cooperation with the Rogue River Valley

Canal Co., which furnishes part of the gage readings. 

Estimates of daily and monthly discharge are withheld until additional data are

obtained.

LOST EIVEB AT OLENE, OREG.

Location. In sec. 14, T. 39 S., R. 10 E., at the highway bridge at Olene.

Itecords available. May 24 to July 30, 1904; May 20, 1907, to March 16, 1912.

Drainage area. 1,290 square miles.

Gage. Vertical staff.

Channel. A permanent rocky riffle, 200 feet below the gage, controls the gage

heights. 

Discharge measurements. Made from highway bridge except during extreme

low water, when the river can be better waded at the riffle. 

Winter flow. Gage heights have never been seriously affected by ice. 

Diversions. At a point 5 miles below this station a dam has been built to divert

the water of Lost River through a slough into Klamath River and thus reclaim

lands bordering on Tule Lake. Backwater from this dam drowned out the Olene

station about March 16, 1912, and the readings were discontinued. 

Accuracy. The conditions at this station have been favorable for good results. 

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

States Reclamation Service but the records have been worked up by the U. S.

Geological Survey.

LOST RIVER AT WILSON BRIDGE, NEAR OLENE, OREG.

Location. In sec. 32, T. 39 S., R. 10 E., at Wilson Bridge, about one-fourth mile

below the diversion dam and about 5 miles below Olene. 

Records available. March 14, 1912 to May 11, 1912. 

Drainage area. Not measured. 

Gage. Vertical staff attached to highway bridge. 

Channel. Clean sand and rocks.

Discharge measurements. Made from the highway bridge. 

Diversions. This station is located just below the dam at which water is at present

diverted into Lost River Slough and thence into Klamath River. During low

water all the water will be diverted from Lost River. 

Accuracy. During the period when there was no diversion the records at this

station should be fairly reliable as a good rating has been determined. 

Cooperation. This station is maintained by the United States Reclamation Service

and the records worked up and published by the Survey.

NOTE. Discharge determined from a fairly well defined rating curve. May 12 to Sept. 30,1912, all flow 

was diverted above the dam, but there was more or less seepage through the nashboards. During Augusr 

this seepage was estimated by the United States Reclamation Service engineers to be about 30 aore-feet.

TITLE LAKE NEAE MEEEILL, 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.

Eecords available. May 17, 1904, to July 31, 1912.

Gage. Vertical staff fastened to post driven in lake bed. The datum of the gage 

at present is 0.83 foot higher than when originally established.

Accuracy. In May, 1907, the gage was found to be 0.83 foot higher than when last 

checked in October, 1904. This was verified in June, 1907, and again in November, 1907. 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. 

On account of this error the gage heights prior to May, 1907, should not be used 

for detailed studies.

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

States Reclamation Service and the records have been prepared for publication 

by the Survey.

MILLER CREEK NEAR LORELLA, OREG.

Location. In sec. 7, T. 40 S., R. 14 E., at the highway bridge 3 miles south of 

Lorella and 1 mile east of the Swingle ranch in Langell Valley. August 10,1904, 

to December, 1908, at station in sec. 12, T. 39 S., R. 13 E., 9 miles northeast of 

Lorella at the lower end of Horsefly Valley.

Records available. April 1, 1909, to September 30, 1912, at present site.

Drainage area. At old station 220 square miles. At new station 270 square miles.

Gage. Friez automatic register. No change in datum.

Channel. Rocky and fairly permanent.

Discharge measurements. During medium and high water, from highway bridge. 

Low-water measurements are made by wading at riffle.

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

the present station.

Winter flow. During the winter months the river freezes over completely, and the 

data obtained at such periods are not reliable. As the total annual flow, however, 

is the important feature, a large error during such periods is admissible without 

affecting the desired results.

Accuracy. The records at this station were somewhat fragmentary until the Friez 

gage was installed January 30,1910, but estimates have been made for all missing 

periods and the resulting values of total run-off have been fairly accurate.

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

States Reclamation Service, and the records computed by the U. S. Geol. Survey. 

No measurements have been secured since 1911.

NOTE. Discharge determined from a fairly well defined rating curve applicable Jan. 1.1911. to June 30, 

1912. On days when gage was not read the discharge was interpolated? or estimated from hydrographs 

of neighboring streams. Discharge below 10 second-feet are only approximate. Owing to lack of recent 

measurements and uncertainties in gage-height record, it was not considered advisable to make estimates 

after June 30,1912.

TRINITY RIVER AT HOOPA, CAL.

Location. At Hoopa Indian Agency, in the NW. £ sec. 25, T. 8 N., R. 4 E., about

1 mile above Hoopa Ferry, and about 11 miles above junction with Klamath

River.

Records available. September 3,1911, to September 30,1912. 

Drainage area. Not measured.

Gage. Staff in three sections on left bank 800 feet above mouth of Supply Creek. 

Channel. Sand and gravel; fairly permanent. 

Discharge measurements. Made from ferry 1 mile below gage. As Supply Creek

enters between gage and ferry, it is necessary to deduct discharge of this stream

from measurements made at ferry to obtain flow at gage.

Estimates are withheld until additional high-water measurements are made.

COFFEE CREEK AT COFFEE, CAL.

Location. At private highway bridge at Coffee, in the NW. J Bee. 4, T. 37 N., R. 8 

W., in the Shasta National Forest, and 5 miles above junction with Trinity River. 

Boulder Creek enters 400 feet above and Little Boulder Creek 1J miles below 

the station.

Records available. December 16, 1910, to September 30, 1912.

Drainage area. Not measured.

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

Channel. Gravel and bowlders; fairly permanent.

Discharge measurements. Made from downstream side of bridge at gage or by 

wading.

Winter flow. Slightly affected by ice during December and January.

Artificial control. From April to July, inclusive, and occasionally throughout the 

remainder of the year, two dams with automatic or "self-shooting" gates are 

operated about 10 miles above the station. The Nash mine operates a dam 

having a working capacity of about 125 acre-feet. The Holland mine, on the 

East Fork, operates 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 the self-shooting 

dam, is subject to some error. Otherwise the results are good.

Cooperation. Gage-height record furnished by United States Forest Service.

EAST FORK OF TRINITY RIVER NEAR TRINITY CENTER, CAL.

Location. At highway bridge, 2J miles southeast of Trinity Center, in the SW.

J sec. 15, T. 36 N., B. 7 W., in the Shasta National Forest, and one-fourth mile

above junction with Trinity River.

Records available. December 15, 1910, to September 30, 1912 (fragmentary). 

Drainage area. Not measured. 

Gage. Vertical staff on downstream end of left abutment of bridge.
KLAMATH RIVER BASIN. 407

Channel. Gravel and small bowlders; appears permanent. The section at the 

bridge is poor for measurements at low stages because of ponded water.

Discharge measurements. Made from downstream side of bridge or by wading.

Diversions. About 400 acres are irrigated from this stream. The principal diversion is the Trinity Farm & Cattle Co.'s canal, which heads about 4 miles above 

the station. Some water is also used for mining purposes.

Accuracy. Eating curve is fairly well denned and results are fair.

Cooperation. Gage-height record furnished by United States Forest Service.

FLUCTUATIONS IN GROUND-WATER LEVELS IN THE 

VALLEY OP SOUTHERN CALIFORNIA.

By W. C. MENDENHALL.

Measurements of fluctuations in ground-water levels were made in 

a series of selected wells in southern California at various times 

during the years 1904 to 1908, inclusive, as an incident in general 

studies of the origin, quantity, and use of the ground-water resources 

of that part of California, and the results were published in WaterSupply Papers 213 and 251. A few additional measurements were 

made in 1909 and 1910 and in the summer of 1912, the latter under 

the direction of Mr. Charles H. Lee in connection with a study for 

the California Conservation Commission of the results of certain 

measures for the conservation of water taken by the larger water 

companies of the San Bernardino Valley.

Results of the later measurements are here assembled as records 

for future comparison and for the use of students of this important 

resource, on which the prosperity of southern California has come to 

depend in so large a measure.

The decade preceding 1904 was a period of very low rainfall in 

this region, so that the ground-water levels at the end of this drydecade the beginning of the period during which measurements 

have been made were presumably lower than at any time since 

settlement began. Since 1904 the precipitation has been somewhat 

above the general average, the three winters of 1904-5, 1905-6, and

1906-7 having yielded an excess of about 25 per cent. During

1907-8, 1909-10, and 1910-11 there was some deficiency, and in the 

winter of 1908-9 precipitation was above the average. On the 

whole, this period of seven seasons has been somewhat more favorable for the maintenance of ground-water levels than can be expected 

as a general average and very much more favorable than the preceding decade.
426 SURFACE WATER SUPPLY, 1912, PART XI.

As is to be expected, the wells that have been measured do not 

exhibit uniform behavior nor even uniform tendencies. Those situated near large streams are restored to their normal level each 

winter, no matter how severely they may have been taxed during 

the preceding irrigation season. Others, remote from sources of 

supply and heavily drawn upon, have exhibited decrease even during the most favorable seasons. In some important districts the 

ground-water level is now (autumn, 1912) well above the alarmingly 

low level of 1904; in others the latest measurements are near, and 

in still others definitely below the lowest level of that period. Two 

important areas in which new low levels are recorded are in the 

vicinity of Los Angeles and at Penis Valley. The condition in and 

about Los Angeles, however, will be cured by the completion of the 

aqueduct and the introduction of Owens Valley water supplies.

Generally speaking, except near the larger streams the ground 

waters have not regained and can not be expected to regain their 

original average level. Where developments are extensive and 

increasing and sources of supply are remote and inadequate the 

present levels the lowest yet attained will be still further lowered.

It is true, however, that one winter of heavy and well-distributed 

rainfall may do much to counteract the depletion of ground-water 

levels that results from several dry seasons, with their necessary 

accompaniment of severe pumping drafts required to supply the 

deficiency in surface waters that is the first and most direct result 

of meager rainfall.

As the data furnished by a series of measurements such as this 

are essential to conclusions as to the amount of water that can be 

taken from underground reservoirs without too greatly depleting the 

supply the Geological Survey has arranged to continue the work by 

making at least two measurements of each well annually, one about 

the time of maximum recharge in the spring and the other at the 

time of maximum depletion in the autumn.
