SURFACE WATER SUPPLY OF PACIFIC COAST 

CALIFORNIA, 1910.

By W. B. CLAPP, F. F. HENSHAW, and H. D. MCGLASHAN.

INTRODUCTION.

AUTHORITY FOR INVESTIGATIONS.

This volume contains results of measurements of the flow of certain 

streams in the United States. The work was performed by the waterresources branch of the United States Geological Survey, either independently or in cooperation with private or State organizations. The 

organic law of the Geological Survey (Stat. L., vol. 20, p. 394) 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 structures, mineral resources, and products of the national domain.

As water is the most abundant and most valuable of the minerals,, 

the investigation of water resources is authorized under the provision 

for examining mineral resources. The work has been supported since 

the fiscal year ending June 30, 1895, by appropriations in successive 

sundry civil bills passed by Congress under the following item:

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.

The appropriations that have been made for this purpose are as 

follows:

Annual appropriations for the fiscal year ending June 30 

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

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

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

SCOPE OF INVESTIGATIONS.

These investigations are not complete nor do they include all the 

streams that might purposefully be studied. The scope of the work 

is limited by the appropriations available. The field covered is the 

widest and the character of the work is believed to be the best possible 

under the controlling conditions. The work would undoubtedly have 

greater scientific importance and ultimately be of more practical value 

if the money now expended for wide areas were concentrated on a few 

small drainage basins; but such a course is impossible because general 

appropriations made by Congress are applicable to all parts of the 

country. Each part demands its proportionate share of the benefits.

It is essential that records of stream flow shall be kept during a 

period of years long enough to determine within reasonable limits the 

entire range of flow from the absolute maximum to the absolute 

minimum. The length of such a period manifestly differs for different 

streams. Experience has shown that the records for some streams 

should cover 5 to 10 years and those for other streams 20 years or even 

more, the limit being determined by the relative importance of the 

stream and the relation of the results to other long-time records on 

adjacent streams.

In the performance of this work an effort is made to reach the highest degree of precision possible with a rational expenditure of time 

and a judicious expenditure of a small amount of money. In all engineering work there is a point' beyond which refinement is needless and 

wasteful, and this statement applies with especial force to stream-flow 

measurements. It is confidently believed that the stream-flow data 

presented in the publications of the Survey are in general sufficiently 

accurate for all practical purposes. Many of the records are, however, of insufficient length, owing to the unforeseen reduction of appropriations and consequent abandonment of stations. All persons 

are cautioned to exercise the greatest care in using such incomplete 

records.

Records have been obtained at nearly 2,000 different points in the 

United States. The surface water supply of small areas in Seward 

Peninsula and the Yukon-Tanana region, Alaska, and in Hawaii has 

also been investigated. During 1910 regular gaging stations were 

maintained by the survey and cooperating organizations at about 

1,100 points in the United States, and many discharge measurements 

were made at other points. Data were also obtained 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 surface water-supply papers and in special papers from 

time to time.
INTRODUCTION.

PUBLICATIONS.

The data on stream flow collected by the United States Geological 

Survey have appeared in the annual reports, bulletins, and watersupply papers. Owing to natural processes of evolution and to 

changes in governmental requirements, the character of the work and 

the territory covered by these different publications have varied 

greatly. For the purpose of uniformity in the presentation of reports 

a general plan has been agreed upon 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 certain natural drainage lines. The areas 

so described are indicated by the following list of papers on surface 

water supply for 1910. The dividing line between the north Atlantic 

and south Atlantic drainage areas lies between York and James

rivers.

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

The records at most of the stations discussed in these reports extend 

over a series of years. An index of the reports containing records 

prior to 1904 has been published in Water-Supply Paper 119.

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

the numbers of the papers on surface water supply published from 

1899 to 1909. Wherever the data for a drainage basin appears in 

two papers the number of one is placed in parentheses and the portion of the basin covered by that paper is indicated in the second 

table. For example, in 1904 the data for .Missouri River were published in Water-Supply Papers 130 and 131, and the portion of the 

records contained in Water-Supply Paper 131, as indicated by the 

second table, is that relating to Platte and Kansas rivers.

The order of treatment of stations in any basin in these papers is 

downstream. The' main stem of any river is determined by measuring or estimating the drainage area; that is, the headwater stream 

having the largest drainage area is considered the continuation of the 

main stream and local changes in name and lake surface are disregarded. Records for all stations from the source to the mouth of the 

main stem of the river are presented first, and records for the tributaries in regular order from source to mouth follow, all records for each 

tributary basin being given before those of the next basin below.
12 SURFACE WATER SUPPLY, 1910, PART XI.

The exceptions to this rule occur in the records for Mississippi River, 

which are given in four parts, as indicated above, and in the records 

for large lakes, where it is simpler to take up the streams in regular 

order around the rim of the lake than to cross back and forth over 

the lake surface.

DEFINITION OF TERMS.

The volume of water flowing in a stream the "run-off" or "discharge" is expressed in several 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 run-off 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-foot, second-feet per square mile, and 

run-off in inches and acre-foot. They may be defined as follows:

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

the rate of discharge of water flowing in a stream 1 foot wide, 1 foot 

deep, at a rate of 1 foot per 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:

"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 in inches" is the depth to which the drainage area would

inches.

EXPLANATION OF DATA *

For each drainage basin there is given a brief general description 

covering such items as area, source, tributaries, topography, geology, 

forestation, rainfall, irrigation, storage, power, and other interesting 

or important facts.

For each regular current-meter gaging station the following data 

so far as available are given: Description of station, list of discharge 

measurements, table of daily gage heights, table of daily discharges,
14 SURFACE WATER SUPPLY, 1910, PART XI.

table of monthly and yearly discharges and run-off. For stations 

located at weirs or dams the gage-height table is omitted.

In addition to statements regarding the location and installation of 

current-meter stations the descriptions give information in regard 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 discharge-measurement table gives the results of the discharge 

measurements made during the year, including the date, name of 

hydrographer, width and area of cross section, gage height, and 

discharge in second-feet.

The table of daily gage heights records the daily fluctuations of 

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

taken each day. At most stations the gage is read 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 daily gage 

heights and daily discharges for the purpose of verifying the published results as follows:

First plot the discharge measurements for the current and earlier 

years on cross-section paper, with gage heights in feet as ordinates 

and discharge in second-feet as abscissas. Then tabulate a number 

of gage heights taken from the daily gage-height table for the complete range of stage given and the corresponding discharges for the 

days selected from the daily discharge table and plot the values on 

cross-section paper. The last points plotted will define the rating 

curve used and will lie among the plotted discharge measurements. 

After drawing the rating curve, a table can be developed by scaling 

off the .discharge in second-feet for each tenth foot of gage height.

INTRODUCTION. 15

These values should be so adjusted that the first differences shall 

always be increasing or constant, except for known backwater 

conditions.

The table of daily discharges gives the discharges 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 page 12, are based.

The field methods used in the collection of the data presented in 

this series of reports are described in the introductory sections of 

Water-Supply Papers 261 to 272, inclusive, "Surface water supply 

of the-United States, 1909." Plate I shows typical gaging stations. 

Plate II shows the various types of current meters 1 used in the work.

ACCURACY AND RELIABILITY OF FIELD DATA AND COMPARATIVE

RESULTS.

The accuracy of stream flow 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 of discharge to stage. Errors of the second group 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 data.

Practically all discharge measurements made under fair conditions 

are well within 5 per cent of the true discharge at the time of observation. Inasmuch as the errors of meter measurements are largely 

compensating, the mean rating curve, when well defined, is much 

more accurate than the individual measurements. Numerous experiments made to test the accuracy of current-meter work show that 

it compares very favorably with the results from standard weirs and, 

owing to simplicity of methods, usually gives results that are much

16 SURFACE WATER SUPPLY, 1910, PART XI.

more reliable than those from stations at dams where the coefficient 

may be uncertain and conditions of flow are complicated.

The work is, of course, dependent on the reliability of the gage 

observers. With relatively few exceptions, the observers perform 

their work honestly. The records are, however, closely watched and 

the cause of any discrepancy is investigated. It is obvious that one 

gage reading a day does not always give the mean height for that 

day. As an almost invariable rule, however, errors from this source 

are compensating and virtually negligible in a period of one month, 

although a single day's reading may, when taken by itself, be considerably in error.

An effort is made to visit every station at least once each year for 

the purpose of making a measurement to determine the constancy of 

conditions of flow since the last measurement made in the preceding 

year, and also to check the elevation of the gage. On account of 

lack of funds or for other causes some stations were not visited during 

the current year. If conditions of flow have been reasonably permanent up to the time of the last preceding measurement, it is considered best to publish estimates of discharge based on the latest 

verified rating curve rather than to omit them altogether, although 

it should be distinctly understood that such records are at" times 

subject to considerable error. This is also true, although to a less 

degree, of the period of records since the date of the last measurement of the current year. As a rule, the accuracy notes are based 

on the assumption that the rating curve used is strictly applicable 

to the current year.

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 monthlydischarge 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" or 

"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.
INTRODUCTION. 17 

USE OF THE DATA.

In general the base data which are collected in the field each year 

by the Survey engineers are published, not only to comply with the 

law, but also for the express purpose of giving to any engineer the 

opportunity of examining the computed results and of changing and 

adjusting them as may seem T?est to him. Although it is believed 

that the rating tables and computed monthly discharges are as good 

as the base data up to and including the current year will warrant, it 

should always be borne in mind that the additional data collected at 

each station from year to year nearly always throw new light on data 

already collected and published, and hence allow more or less improvement in the computed results of earlier years. It is therefore expected 

that the engineer who makes use of the figures presented in these 

papers will verify all ratings and make such adjustments for earlier 

years as may seem necessary. The work of compiling, studying, 

revising, and republishing data for different drainage basins for 5 or 10 

year periods or more is carried on by the United States Geological 

Survey so far as the funds for such work are available.

The estimates in the table of monthly discharge are so arranged 

as to give only a general idea of the conditions of flow at the station, 

and it is not expected that they will be used for other than preliminary 

estimates.

The daily discharges are published to allow a more detailed study 

of the variation in flow and to determine the periods of deficient flow.

*

COOPERATIVE DATA.

Cooperative data of various kinds and data regarding the run-off 

at many stations maintained wholly by private funds are incorporated 

in the surface water-supply reports of the United States Geological 

Survey.

Many stations throughout the country are maintained for specific 

purposes by private parties who supply the records gratuitously to 

the United States Geological Survey for publication. When such 

records are furnished by responsible parties and appear to be reasonably accurate, they are verified, so far as possible, and estimated 

values of accuracy are given. As it is, however, impossible to verify 

completely all such records furnished because of lack of funds or 

for other causes they are published for what they are worth, as they 

are of value as a matter of record and afford at least approximate 

information regarding stream flow at the particular localities. The 

Survey does not, however, assume any responsibility for inaccuracies 

found in such records, although most of them are believed to be 

reasonably good. Records that are clearly worthless or misleading 

are not published.

SOUTH PACIFIC OCEAN DRAINAGE BASINS. 23 

SOUTH PACIFIC OCEAN DRAINAGE BASINS. 

GENERAL FEATURES.

The South Pacific Ocean drainage basins include all streams south 

of San Francisco Bay that drain the western slope of the Coast 

Range and enter the Pacific either directly or indirectly. The 

average width of the region thus drained is nearly 50 miles and its 

total area is 23,000 square miles. The low-water flow of the streams 

of this area is very small, and in many of them all the water disappears 

in the sand and gravel beds below the canyons. In the winter, 

however, the streams are torrential and discharge large volumes of 

water. North of Santa Barbara the general course of the streams 

is northwestward; south of Santa Barbara, however, which is approximately opposite the intersection of the Coast Range by the Tehachapi 

Range, the general direction is southwestward.

TIA JtTANA RIVER BASIN. 

COTTONWOOD CREEK AND DULZURA CANAL NEAR JAMUL, CAL.

Tia Juana River discharges into the Pacific Ocean below San Diego 

Bay, near the Mexican boundary. Its principal tributary, Cottonwood Creek, rises in the Laguna Mountains of the Coast Range, and 

flows south and west for about 20 miles, where it is joined by Pine 

Valley Creek from the north; it then flows southwestward 12 miles 

to its junction with Tia Juana River at the Mexican boundary, about 

22 miles east of the coast line. The total drainage area of Cottonwood Creek above its junction with Tia, Juana River is approximately 

340 square miles. It lies south of the Sweetwater and Otay River 

basins and is the most southerly stream in San Diego County. Pine 

Valley Creek is its only important tributary.

The gaging station, which was established December 14, .1905, 

is at the Barrett dam site, in SW. \ sec. 15, T. 17 S., R. 3 E., 6 miles 

above the San Diego Campo road, and 12 miles east of Jamul.

Pine Valley Creek enters Cottpnwood Creek 1 mile 'and Lyons 

Creek half a mile above the gaging station. The drainage area above 

the station, including Pine Valley Creek, is 270 square miles.

The Southern California Mountain Water Co. diverts water from 

Pine Valley and Cottonwood creeks about half a mile above their 

junction, by way of Dulzura canal (13.4 miles long) to the headwaters of Dulzura Creek, whence it flows 12 miles to lower Otay 

reservoir, which supplies water to the city of San Diego. The 

capacity of the canal is about 60 second-feet. The amount diverted is 

measured in the diversion flume about 1^ miles below the intake and 

one-fourth mile below the station on Cottonwood Creek. A staff gage 

is located at the measuring section in the flume.
24 SURFACE WATER SUPPLY, 1910, PART XI.

Several gages with independent datums have been installed at this 

station. Two vertical staff gages are now used. The upper one is 

on the left bank near the end of the dam and reads the depth of the 

water on the crest of the dam. The lower gage is on the upstream 

side of the dam near the right bank, and its datum is 2.50 feet lower. 

Gage heights for 1909 and 1910 are referred to lower gage datum.

Discharge measurements to determine the excess water not diverted 

to the lower Otay reservoir are made at the low concrete dam, b'ack 

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 

opening 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 water, when floats are used.

The gage height records are furnished by the Southern California 

Mountain Water Co. The results obtained are only fair.

SWEETWATER RIVER BASIN. 

SWEETWATER RIVER NEAR DESCANSO, CAL.

Sweetwater River rises in the south and east slope of the Cuyamaca 

Mountains of the Coast Range, flows nearly due south for a distance 

of 15 miles, then turns to the west and southwest and discharges 

into San Diego Bay south of National City. Its length is 45 miles 

and its area comprises approximately 215 square miles, the greater 

part of which is in mountainous country. The basin is extremely 

narrow. It lies directly south of San Diego River and north of the 

Otay and Cottonwood Creek basins.

A record of run-off kept at the Sweetwater reservoir from 1888 to 

1905 by the San Diego Land & Town Co. was published in WaterSupply Paper 251, 1910, page 106.

The gaging station, which is located at the Ellis ranch, 1£ miles 

below Descanso post office, in the SE. £ sec. 25, T. 15 S., R. 3 E., 

was established November 21, 1905.

Guatay Creek enters the river from the east about 2 miles above 

the gaging station. About one-fourth second-foot of water is 

diverted above the station for irrigation on the Ellis ranch. About 

20 miles below water for irrigation is pumped from wells along the 

banks of the stream.

The staff gage is in three sections on the left bank. No change 

has been made in the datum of the gage since the station was established. Discharge measurements are made from a cable or by 

wading near the gage.

Discharge for 1910 was estimated by the indirect method for 

shifting channels and from rating tables covering short periods. The 

record may be considered fair.

SOUTH PACIFIC OCEAN DRAINAGE BASINS. -31

i

SAN DIEGO RIVER BASIN. 

SAN DIEGO RIVER AND FLUME NEAR LAKESIDE, OAL.

San Diego River rises in the Cuyamaca Mountains on the western 

slope of the Coast Range and flows in a southwesterly direction, 

discharging into Pacific Ocean through False Bay at the northern 

boundary of San Diego City. Its length is about 50 miles, half of 

which lies in the mountains above the town of Lakeside. The San 

Diego basin lies directly south of the Santa Ysabel basin and north of 

Sweetwater River basin.

The San Diego has several small tributaries, the most important 

being Coleman, Cedar, Boulder, South Fork, and Chocolate creeks, 

all of which enter from the east and south above Lakeside. San 

Vicente Creek, the only important tributary from the north, enters 

the river at Lakeside.

The gaging station, which is located about 1 mile above the San 

Diego, Cuyamaca & Eastern Railway station, at crossing of the road 

from Lakeside to Padre Barona Valley, on the El Cajon land grant, 

was established December 3, 1905.

Chocolate Creek enters the river from the south 7 miles above, and 

San Vicente Creek from the north 1 mile below the gaging station. 

The drainage area at this point is 208 square miles.

The San Diego flume diverts water from the river at a point onehalf mile below the junction of Boulder Creek and about 15 miles 

above the gaging station. This flume diverts all the low flow of the 

river and a sufficient amount of the winter flow to fill La Mesa storage 

reservoir. The present capacity of the flume is about 16 second-feet. 

In addition, there are five pumping plants, located from 1 to 3 miles 

above the station, that obtain water for irrigation from wells along 

the banks of the stream. Their capacity ranges from about one-half 

to 2^ second-feet. There are several similar pumping plants below 

the station.

The staff gage is in three sections on the left bank at the cable 

from which discharge measurements are made. The gage datum has 

remained unchanged since the station was established.

The gaging station on the San Diego flume is located at the trestle 

crossing at Los Coches Creek, 3£ miles southeast of Lakeside. The 

gage heights are furnished by the San Diego Flume Co.

The conditions at the river station are extremely bad for procuring 

accurate estimates of discharge. The channel is wide and is composed of sand, which is constantly shifting and changing the position 

of the stream. Many discharge measurements are necessary to procure reliable estimates of discharge.
32 SURFACE WATER SUPPLY, 1910, PART XI.

The discharge for 1910 was determined by the indirect method for 

shifting channels and from rating tables covering short periods of 

time. The record may be considered fair.

SAN DIEGTJITO RIVER BASIN.1 

SANTA YSABEL CREEK NEAR ESCONDIDO, CAL.

San Diegaito River, or Santa Ysabel Creek, as it is known from its 

source to the San Pasqual Valley, rises in the Volcan Mountains on the 

western slope of the Coast Range and flows westward through San 

Pasqual Valley, below which it takes its true name, and empties into 

the Pacific Ocean midway between Oceanside and San Diego. Its 

length is 50 miles, and the maximum width of the drainage basin about 

15 miles. The total drainage area is approximately 340 square miles. 

It lies south of San Luis River and north of the San Diego River 

basin.

Numerous small tributaries enter San Ysabel Creek between its 

source and San Pasqual Valley, the most important being Black 

Canyon and Temescal creeks from the north and Santa Maria Creek 

from the south. Above San Pasqual Valley the creek maintains a 

light flow throughout the year, but below that point the channel is 

dry during the summer months.

The gaging station, which is located below the mouth of the narrow 

canyon at the upper end of the San Pasqual Valley, in the SW. J 

sec. 31, T. 12 S., R. 1 E., 10 miles southeast of Escondido, was established Dec. 17, 1905.

Roden Canyon Creek and Temescal Creek, tributaries from the 

north, enter the Santa Ysabel Creek 1£ and 5 miles, respectively, 

above the gaging station. Santa Maria Creek enters from the south 

4 miles below the gaging station.

i Called Bernardo Biver in previous reports.
SOUTH PACIFIC OCEAN DRAINAGE BASINS. 37

No water is diverted from this stream above the gaging station. 

Within half a mile below the station, in the San Pasqual Valley, are 

two small irrigation canals. A third canal, with a capacity of about 

45 second-feet, heads about 1 mile below the station, and about 2 

miles below is a fourth, with a capacity of about 25 second-feet.

The gage is an inclined staff on the left bank. The datum of the 

gage has not been changed since the station was established.

At high stages discharge measurements are made from a cable 

at the gage.

The conditions for obtaining accurate discharge data at this station are extremely poor. The channel is composed of shifting sand 

which scours out at high stages of the stream and immediately fills 

in again as the flow decreases. Frequent measurements of discharge 

are necessary to procure reliable estimates.

The discharge for 1910 was estimated by the indirect method for 

shifting channels and from rating curves covering short periods of 

time. The record is approximate.

SAN LUIS BEY RIVER BASIN. 

SAN LUIS REY RIVER NEAR PALA, CAL.

San Luis Rey River drains an area about 575 square miles in 

extent lying wholly in the northern part of San Diego County and 

extending from the crest of the Coast Range to the Pacific Ocean, 

a distance of 65 miles, with a maximum width of about 16 miles.

The river is formed by many small streams which have their 

sources in the higher elevations of the Coast Range and come together 

at the lower or west end of what is known as Warner's Valley. 

Below this point the river flows for a distance of 10 miles through 

a deep, narrow canyon with a heavy grade, then over a sandy and 

gravelly bed with light grade for some 40 miles, finally discharging 

into the Pacific Ocean at Oceanside.

This station, which is located at the road crossing to Sickler's 

mill, 4 miles above Pala, in the NW. i sec. 31, T. 9 S., R. 1 W., was 

established October 9, 1903.

No tributaries enter the river near the gaging station. Water is 

diverted from the river during the winter and spring months at a 

point in the rough canyon about 11 miles above the station to a 

storage reservoir, and is used during the summer period for irrigation 

and municipal supply at Esconiddo and the surrounding country. /' / 

About 3 miles below this point there is a diversion for irrigation 

on the Rincon Indian Reservation. One mile above the station a 

small amount is diverted for use on the Sickler ranch. The only 

diversion below the station is that used for irrigation on the Pala 

Indian Reservation. There are several pumping plants between 

Pala and the mouth, which obtain water from wells along the banks 

of the stream. The drainage area above the station is 318 square 

miles.

The staff gage is in two sections on the left bank at the cable 

from which discharge measurements are made. The datum of the 

gage was lowered 4.66 feet on November 13, 1906.

Conditions for obtaining accurate discharge data are poor. The

channel is wide, is composed of sand, gra 

subject to constant change. The current

The estimates of discharge were prepared from rating curves 

covering short periods of time and by interpolation on the days

when the gage was not read. The record may be considered good.

SANTA ANA RIVER BASIN.

SANTA ANA EIVBR AND MBNTONB POWER CO.'s CANAL NEAR

MENTONE, CAL.

Of the three important streams' Santa Ana, San Gabriel, and Los 

Angeles rivers that traverse the valley of southern California, the 

Santa Ana is the most important. Its drainage basin, lying south 

of the San Bernardino Mountains and the Sierra Madre and taking 

waters from their southern slopes, is the most' eastern and comprises 

by far the largest area, including the northern part of Orange County, 

the northwestern part of Riverside County, and the southwestern 

part of San Bernardino County. Of the total drainage area, covering between 1,800 and 1,900 square miles, about two-thirds are in 

the valley, but only a few hundred yield much run-off.

The Santa Ana rises in the heart of the San Bernardino Mountains, 

about 30 miles east of Highland, and flows westward for about 25 

miles to the mouth of its upper canyon; thence southwest ward 

across San Bernardino Valley, through the lower canyon in the

Santa Ana Mountains, and across the Coastal Plain to the Pacific 

Ocean at Newport Beach. Although the course of the stream measures about 100 miles, there is continuous surface flow from mountain 

to sea only during winter floods.

Many small streams from the southern slope of the San Bernardino 

Mountains and a few from the Sierra Madre west of the Cajon Pass 

flow toward the Santa Ana, but some of these discharge water to 

the main stream only in the flood seasons, the ordinary flow either 

being diverted or sinking into the sand and gravel of San Bernardino 

Valley. The principal tributaries are Bear, Alder, Mill, Lytle, and 

Chino creeks.

This station, which is located at the road crossing opposite Warm 

Spring Canyon, about three-fourths of a mile below the headworks 

of the Mentone Power Co.'s canal, 5 miles northeast of Mentone, in 

the SW. | sec. 34, T. 1 N., R. 2 W., S. B. M., was established in 

June, 1896, and is about 2 miles below the mouth of Alder Creek.

Practically all the low-water flow is diverted above the station 

into the power canal. After leaving the power house this water is 

carried across the river to an irrigation canal. The flow in the canal 

is measured by a weir and is added to that at the station in order to 

obtain the total for the stream. The acquired water rights exceed 

the low-water flow.

The original staff gage was fastened to the left bank about 100 

feet above the ford. The gage datum was lowered June 30, 1903. 

January 1, 1910, a severe flood carried away both gage and the car 

and cable from which discharge measurements were made and 

destroyed existing bench marks. The channel was completely 

changed. A new inclined staff gage was installed January 23,1910, on 

the left bank, 50 feet above the former location, and set at a new 

datum. On February 25, 1910, however, it was found desirable to 

install a gage in the right channel, which carried most of the water. 

All gage heights prior to Februarf 25 have been corrected to the 

datum of the west gage from a relation curve obtained from synchronous readings of the two gages.

Discharge measurements are made by wading at low and medium 

stages. As it is very difficult to reach the station at high stages the 

cable has not been replaced.

Conditions for obtaining accurate discharge data are fair. The 

stream has a rocky bed and is subject to slight change. At high 

stages the current is swift and it is difficult to get accurate gagings. 

The records are fairly satisfactory.

SOUTH PACIFIC OCEAN DRAINAGE BASINS. 47

SAN GABRIEL RIVER BASIN. 

SAN GABEIEL EIVEE AND POWEE CANAL NEAR AZUSA, CAL.

San Gabriel River is one of the three most important streams 

traversing the valley of southern California. Its drainage basin lies 

wholly in Los Angeles County west of the Santa Ana basin and east 

of the Los Angeles basin, and stretches from the crest of the Sierra 

Madre to the Pacific, a distance of about 50 miles. Its total drainage 

area is approximately 700 square miles, about one-third of which 

consists of mountain slopes, which contribute practically all of the 

run-off except in heavy storms. The remaining two-thirds is 

embraced in the San Gabriel Valley at the base of the mountains 

and in the coastal plain southeast of the city of Los Angeles.

The main stream is formed by the junction of two principal forks, 

one from the north and east and the other from the west. Each of 

the branches receives many tributaries from the crests of the surrounding ranges. The headwaters come from the western slope of 

San Antonio Peak (Old Baldy), altitude 10,080 feet, and from the 

southern slope of other high peaks at the north, such as North Baldy 

and Islip mountains. - The west fork drains the northern slope of 

Mount Wilson, the eastern and northern slopes of San Gabriel Peak, 

and a portion of the southern slopes of the main range to the north. 

It joins the main stream about 8 miles above the mouth of the canyon. The general course of the stream is southwestward. After 

leaving the mountains it traverses San Gabriel Valley in a wide wash 

of sand, gravel, and bowlders, then breaks through the range of foothills separating San Gabriel Valley from the coastal plain at a point 

called The Narrows, about 5 miles northwest of Whittier, and enters 

the coastal plain, across which it flows to its mouth in Alamitos Bay, 

a few miles east of Long Beach. The total length of the stream is 

about 65 or 70 miles.

The principal tributaries of San Gabriel River are Fish Fork and 

Cattle Creek from the east and Iron and West forks from the west.

The basin is rather poorly forested, having a sparse timber growth 

on the higher slopes and brush with some scattering timber on the 

middle and lower elevations.

This station, which is located just above the road crossing at the 

mouth of the canyon, about one-fourth mile above the Pacific Light 

& Power Co.'s power house and 2 miles north of Azusa, in the NW. | 

sec. 23, T. 1 N., R. 10 W., S. B. M., was established in 1896. Estimates of flow were very unsatisfactory until after the completion of 

the power canal in 1898.

The station is well below all tributaries and is several miles below 

the power and irrigation diversions.

The gage is an inclined staff in several sections, on the left bank.
48 SURFACE WATER SUPPLY, 1910, PAET XI.

Discharge measurements are made from a cable at the gage.

The flow in the canal is measured by a weir and is added to that at 

the station to obtain the total flow of the stream. Various temporary 

diversions for irrigation just above the station affect the discharge. 

The acquired water rights greatly exceed the low-water flow of the 

stream.

The channel is composed of gravel and bowlders and is subject to 

considerable change, especially above and below the measuring section. The current is swift, and measurements at flood stages are 

difficult.

The rating curve for 1910 is fairly well defined for low and medium 

stages. The record for high stages is approximate.

LOS ANGELES RIVER BASIN. 

ARROYO SECO NEAK PASADENA, CAL.

Los Angeles Kiver is formed by Tujunga, Pacoima, and other small 

creeks, whose sources lie in the Sierra Madre northeast of the city of 

Los Angeles. These streams leave the mountains at a point about 25 

miles above the city and enter the comparatively flat country of tKe 

San Fernando Valley, where, except at times of excessive flood, the 

waters disappear in the sand and gravel washes. At the lower end of 

this valley is a secondary range of hills, extending from east to west, 

and bed-rock obstruction forces the waters to the surface to form what 

is known as Los Angeles Kiver. Below this point the river flows 

through the flat country of the Los Angeles Valley arid enters the 

Pacific near the town of Long Beach.

At the city of Los Angeles it is joined by Arroyo Seco, which drains 

an area comprising 21 square miles of the Sierra Madre. This stream 

issues from the mountains on the west side of Pasadena Mesa, and 

passes through an opening in a granite spyr known as Devils Gate. 

Between the point where it leaves th«enountain and Devils Gate lies a 

broad river bottom 2 miles long, composed of coarse material. In 

passing over this the water sinks rapidly, diminishing in volume of 

flood water from the mouth of the canyon to Devils Gate.

During the summer months the entire flow of Los Angeles Kiver 

is diverted at a point about 5 miles above Los Angeles for the supply 

of the city, only a small amount of water passing this point except 

during flood periods.
52 SURFACE WATER SUPPLY, 1910, PART XI.

The gaging station, which is located in the SE. f sec. 30, T. 2 N., 

R. 12 W., S. B. M., at the ranger's camp in the Angeles National 

Forest, about 4 miles north of Pasadena, was established December 1, 

1910.

The staff gage is in two sections, fastened to an alder tree on the 

right bank, 300 feet southeast of the ranger's cabin. Discharge measurements are made by wading near the gage.

This station is maintained in cooperation with the United States 

Forest Service.

No estimate has been prepared for 1910.

The following discharge measurement was made by W. V. Hardy, 

by wading about 50 feet below gage:

December 1, 1910: Width, 3.5 feet; area 1.4 square feet; gage height, 3.44 feet; discharge, 1.4 second-feet.

SANTA YNEZ RIVER BASIN.

GENERAL FEATURES.

Santa Ynez River is the only important stream lying wholly in 

Santa Barbara County. Its drainage basin lies north of the Santa 

Ynez Mountains, extending for a distance of about 80 miles parallel 

to the coast line, and comprising approximately 900 square miles. 

Four-fifths of this area is mountainous, including the north slope of 

the Santa Ynez and the south slope of the San Raf ael Mountains, and 

furnishes practically all of the run-off.

Santa Ynez River rises near the boundary line between Ventura and 

Santa Barbara counties, where*the Santa Ynez and San Rafael 

ranges merge, flows nearly due west, and enters the Pacific Ocean 

at Surf, about 8 miles north of Point Arguello lighthouse, where 

the coast line makes a sharp turn to the north.

Small tributaries are numerous, but the only one of Importance is 

Mono Creek, which drains 120 square miles of the southern slope of 

the San Rafael Mountains, and joins the Santa Ynez River about 13 

miles below its source.
SOUTH PACIFIC OCEAN DRAINAGE BASINS. 53

SANTA YNEZ EIVER NEAR SANTA BARBARA, CAL.

This station was originally established on November 21, 1902, 

above the mouth of Mono Creek. On November 1, 1903, the station was moved downstream about 5 miles to a point about onefourth mile below the Gibraltar dam site, in the NE. £ NE. £ sec. 15, 

T. 5 N., R. 27 W., S. B. M., and about 12 miles north of Santa Barbara.

Mono Creek enters about 3£ miles above the station. No 'water 

is diverted above the gage. Water rights far exceed the mean lowwater flow of the stream. The drainage area above the station is 

about 207 square miles.

The staff gage, in three sections, is on the right bank, about 300 

yards below the north portal of the Santa Barbara city waterworks 

tunnel now under construction. The gage datum at the new station 

has not been changed. No records were obtained during 1909.

The channel is composed of sand and gravel and is fairly permanent. As no discharge measurements have been made recently, no 

estimates of daily discharge have been prepared for 1910.

The station is maintained by the city of Santa Barbara. The gageheight record has been furnished by the board of water commissioners 

through their engineer, Lee M. Hyde.

54 SURFACE WATER SUPPLY, 1910, PART XI.

SANTA YNEZ RIVER NEAR LOMPOC, CAL.

This station, which was established November 10, 1906, was 

originally located at the wagon bridge 1J miles east of Lompoc, in 

La Mision Vieja de la Purisima land grant. Early in January, 1907, 

the bridge was destroyed by heavy floods. A new bridge was built 

during the summer of 1907, and the station was reestablished September 25, 1907, at the same location.

No tributaries enter the stream in the vicinity of the station and 

no diversions have been made above since the station was established. 

The headworks of canals previously diverting water were destroyed 

by floods and have not been reconstructed. Acquired water rights 

exceed the low flow of the stream. The drainage area above the 

station is about 785 square miles. There are several pumping plants 

above the station that obtain water for irrigation from wells along 

the banks of the stream.

The gage is a vertical staff on the pier of the bridge from which 

discharge measurements are made. The datum of the gage has 

remained unchanged since the station was established.

The conditions at this station are extremely unfavorable for accurate results. The channel is wide and the stream shifts constantly.

The estimates for 1910 can be considered fair for low stages and 

only approximate for high, as no high water measurements were 

obtained.

SAUNAS RIVER BASIN.1 

ARROYO SECO NEAR SOLEDAD, CAL.

The Salinas River basin lies almost wholly in Monterey and San 

Luis Obispo counties, and comprises an area about 4,780 square 

miles in extent, having a length of 150 miles northwest-southeast 

and a maximum width of about 45 miles.

The Salinas rises on the eastern slope of the Santa tucia Range, 

near the southern end of the basin and flows northwestward, parallel 

to the coast, to its mouth, about 4 miles southwest of Castroville.

.The river has many tributaries, all as torrential and erratic as the 

Sah'nas itself, which has a very heavy discharge in winter and no 

surface run-off in summer ordinarily except below Soledad. The 

most important tributaries from north to south are Arroyo Seco, 

San Antonio River, and Nacimiento River from the west and San 

Lorenzo and Estrella creeks from the east. The tributaries from the 

west are peculiar in that they lie west of secondary ranges parallel 

to the main range and flow southeastward for the greater part of 

their length, parallel but in a course directly opposite to the general 

course of Salinas River.

The gaging station on Arroyo Seco was established January 1, 1901, 

at Pettitt's ranch, about 15 miles south of Soledad, in sec. 21, T. 19 

S., R. 6 E.

No water is diverted above the station. The dark Colony 

Water Co., irrigating about 4,000 acres, and the Spreckles Sugar 

Co. about 3,500 acres, divert water 1^ and 3 miles, respectively, below 

the station. These canals head above the broad wash of gravel 

and sand into which the low-water sinks and disappears, and from 

which the stream receives the name Arroyo Seco.

The staff gage is in two sections on the right bank.

1 For a detailed discussion of the water resources of Salinas Valley see Water-Supply Paper 89.
SOUTH PACIFIC OCEAN DRAINAGE BASINS. 57

Discharge measurements are made from a cable 300 feet below the 

The channel shifts more or less during high water, and the 

current is very swift. Measurements made at such stages may be 

considerably in error.

The 1910 rating curve is fairly well defined and the record may be 

considered fair.

SAN FRANCISCO BAY DRAINAGE BASINS.

The great central valley of California, including an area about 

64,000 square miles in extent lying between the Coast Range on the 

west and the Sierra Nevada on the east, is drained by two trunk 

streams. From the north comes the Sacramento; from the south the 

San Joaquin; both discharge their waters into Suisun Bay, whence 

they find outlet through Carquinez Strait and San Pablo Bay into 

San Francisco Bay, passing finally through the Golden Gate into the 

Pacific Ocean.

SAN JOAQTJIN RIVER SYSTEM.

GENERAL FEATURES.

The San Joaquin drainage basin is the southern lobe of the great 

central basin of California and lies southeast of an imaginary line 

drawn from San Francisco Bay to Lake Tahoe. The rim of the 

basin is determined by the crest of the Sierra Nevada at the east, the 

Tehachapi Range at the south, and the Coast Range at the west. 

The basin is somewhat larger than the Sacramento Basin, with which 

it merges at the north. It has a length of about 280 miles northwestsoutheast and a width of about 125 miles. It is roughly rectangular 

in shape, and comprises a total area of about 32,700 square miles.

San Joaquin River rises in the high Sierra south of the Yosemite 

National Park, about halfway between the north and south ends of 

the basin, and flows southwestward to the trough of the San Joaquin 

Valley, whence it takes a northwestward course to its mouth. It has 

a total length of approximately 350 miles 125 miles in the mountains 

and 225 in the valley. It discharges into Suisun Bay, about 50 miles
60 SURFACE WATER SUPPLY, 1910, PART XI.

by water from San Francisco. It is navigable as far as Stockton, 

about 50 miles above its mouth.

All the important tributaries of San Joaquin drain parts of the 

western slope of the Sierra, take a course parallel to the upper San 

Joaquin that is, southwestward and enter from the east. In order 

from south to north they are Fresno, Chowchilla, Merced, Tuolumne, 

Stanislaus, Calaveras, and Mokelumne rivers. The principal streams 

from the Sierra south of the upper San Joaquin, in order from north 

to south, are Kings, Kaweah, Tule, and Kern rivers. These lastnamed streams, however, are not directly tributary to the San 

Joaquin, for they are lost in the Tulare Lake depression, which, under 

normal conditions, has no suface outlet to the San Joaquin. Kings 

River discharges partly into Tulare Lake and partly into the San 

Joaquin. Besides the North, Middle, and South forks, the upper San 

Joaquin has many smaller tributaries.

SAN JOAQUIN RIVER NEAR FRIANT, CAL.1

This station, which is located in the SE. i sec. 34, T. 10 S., R. 21 E., 

at the Fort Miller ranch house, about 4 miles above the town of Friant, 

was established Oct. 18, 1907.

No important tributaries enter near the station and no water is 

diverted above except for water-power development, all such diverted 

water being returned to the river channel above the station. The 

entire flow of the stream is controlled by existing water rights, 

involving all irrigable lands tributary to San Joaquin River.

The staff gage is in two sections on the left bank; no change has 

been made in the gage datum since the station was established. 

Discharge measurements are made from a cable near the gage.

Conditions for obtaining accurate discharge data are fair. At low 

stages the current is very sluggish, but at such times check measurements can be made from the bridge at Friant. The channel is subject to slight changes which may somewhat affect the accuracy.

The 1909 curve was slightly revised for 1910 and is well defined. 

The record may be considered excellent.

SAN JOAQUIN RIVER AT HERNDON, CAL.

This station is at the Southern Pacific Railroad bridge, in sec. 31, 

T. 12 S., E. 19 E., about 12 miles northwest of Fresno and 20 miles 

below Friant. In 1879 the engineering department of the Southern 

Pacific Co. set a staff gage on the old trestle bridge, which was used 

for the regular gaging station established at the beginning of 1895. 

In 1899 the trestle was replaced by a steel bridge, to the center pier 

of which a new vertical staff gage was placed at the datum of the old 

gage. Meter measurements were discontinued at the end of 1901, 

because of the continual change in the section due to shifting sand'. 

Since that date only a gage record has been kept.

Gage records will no longer be published for this station, since 

without frequent discharge measurements they do not accurately 

indicate the discharge.

TULARE LAKE BASIN. 

GENERAL FEATURES.

The Tulare Lake basin is situated near the south end of the San 

Joaquin Valley and embraces that part of the valley bounded by the 

Kings Elver delta at the north and the Kern Eiver delta at the south.

Its lowest area lies in the trough of the valley and for several 

hundred years has been covered most of the time by a shallow freshwater lake, the depth and extent of which have fluctuated with the 

season and the caprice of the delta rivers supplying it. Probably 

within the last hundred years the entire flow of Kern, Tule, and 

Kaweah rivers has entered this lake and a large part, if not all, of 

that of Kings Eiver; but at the present time only the Kaweah and the 

Tule, south of Kings and north of Kern Eiver, are wholly tributary
SAN FRANCISCO BAY DBAINAGE BASINS. 63

to the Tulare basin. At high stages Kings River discharges in part 

into this basin, and at times overflow may reach it from the Kern 

basin at the south.

TULARE LAKE IK KINGS COUNTY, GAL.

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.1

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., M. D. B. and M. 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. The datum on this gage is 171.0 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.

Below is the gage record, showing the actual depth of the water in 

the lowest point of the lake bed, for 1910.

i The fluctuations in level of Tulare Lake are described in Water-Supply Paper U. S. Geol. Survey No. 

271,1911, pp. 171-174.

KERN RIVER BASIN.

GENERAL FEATURES.

The Kern River basin, the largest and most southern of all the areas 

tributary to the San Joaquin Valley from the Sierra, also extends 

farther east than any of the other basins and differs from them in 

that its main axis is north and south instead of east and west. It is 

long and comparatively narrow, and lies west of the main high Sierra 

divide, which separates it from the basins of Kaweah and Tule rivers 

and southern foothill streams at the west. It is separated from Kings 

River basin at the north by a cross range about 15 miles long, known 

as( the Kings-Kern divide. To the east of this basin is the southern 

part of Owens Valley basin and the rough arid region south of Owens 

Lake and north of the Mohave Desert. The basin is about 85 miles 

long and 25 to 30 miles wide.

Kern River has its source in numerous glacial lakes nestling in the 

shadow of many high peaks on the main Sierra divide and on the 

Kings-Kern and the Great Western divides. The main stream flows 

directly southward for about 70 miles, then southwestward to the 

mouth of its canyon, a few miles northeast of Bakersfield, where it 

enters Kern basin, at the southern end of the San Joaquin Valley. 

No water from Kern River has reached the San Joaquin in recent 

years. The total length of Kern River from its source to Bakersfield 

is about 140 miles. Its total drainage area above the valley rim is 

about 2,570 square miles.

The chief tributary of Kern River is South Fork. Above the point 

of confluence the two streams have about equal lengths and drainage 

areas, and are parallel to each other and to the marginal rims. Each 

receives many short tributaries from the east and the west. The most 

important ones, however, Big Arroyo and Rattlesnake creeks and
SAN FRANCISCO BAY DRAINAGE BASINS. 65

Little Kern River from the west, and Gold Trout Creek from the east, 

enter the main stream above North Fork.

KERN RIVER AT ISABELLA, CAL. '

This station was established October 5, 1910, at the wagon bridge 

about half a mile north of Isabella, in the SW. J sec. 17, T. 26 S., R. 

33 E.

Cowell Creek enters about 6 miles above and the South Fork joins 

the main river one-half mile below the station. Several small canals 

take water for irrigation above Isabella. To determine the total discharge of the river it is necessary to add the flow of the Kern River 

Power Co.'s canal. The intake of this canal is one-fourth mile below 

Kernville and about 3^ miles above the station.

The gage is a vertical staff fastened to a large cottonwood tree on 

the left bank. Discharge measurements are made from the bridge 

100 feet above the gage.

The right bank is high; the left bank is overflowed during extreme 

high water. The channel is composed of gravel and cobblestones and 

appears permanent.

This station is maintained in cooperation with the United States 

Forest Service.

No estimates of daily or monthly discharge have been prepared for 

1910.

KERN RIVER NEAR BAKERSFIELD, CAL.

This station, which has been maintained by the Kern County Land 

Co. to furnish a basis for the equitable division of the water of Kern 

River between different appropriators, is located at the mouth of the 

lower canyon, about 5 miles northeast of Bakersfield, at what is 

known as the "first point of measurement," in sec. 2, T. 29 S., R. 28 E. 

It was established September 29, 1893, by Walter James, chief .engineer of the Kern County Land Co.

No tributaries enter below the station and only a few unimportant 

ones for 50 miles above.

Water diverted for power development above the station is returned to the river. Except for local irrigation in the valleys 

around Kernville no water is diverted for irrigation above the station. 

Below the point of measurement, however, the total flow of the river, 

except at flood stages, is diverted by the Kern County Land Co. and 

the Miller & Lux interests, which own all the water rights on lower 

Kern River.

The gage height record is obtained by an automatic water-stage register. Discharge measurements are made from the footbridge near 

the gage.

Determinations of daily discharge are published as furnished by the 

Kern County Land Co. through its engineer, A. K. Warren. Frequent 

discharge measurements are made and the record is excellent.

SOUTH FORK OF KERN RIVER AT ISABELLA, CAL.

This station, which is located at the highway bridge at Isabella, 

in the NW. J sec. 20, T. 26 S., R. 33 E., was established October 5,1910.

Fay Creek and Kelso Creek enter about 10 miles above the station 

and the South Fork joins the main river about half a mile below 

Isabella. The station is below all diversions and the low-water flow 

is entirely used for irrigation. Twenty-eight ditches, ranging in 

capacity from 8 to 40 second-feet, divert water from this stream for 

irrigation in South Fork Valley. The upper ditches head about 20 

miles above the mouth of the river.

The gage is a vertical staff fastened to the piling of the middle bent 

of the bridge.

Discharge measurements are made from the bridge.

Both banks are high and wooded and not subject to overflow. The 

channel, which is composed of sand, is somewhat shifting and the 

current is moderately swift.

This station is maintained in cooperation with the United States 

Forest Service.

No estimate of daily or monthly discharge has been prepared for 

1910.

WHITE RIVER BASIN.

DEER CREEK AT HOT SPRINGS, CAL.

White River and Deer Creek, its principal tributary, which drain 

an area in Tulare County south of Tule River, rise on the Greenhorn 

Mountains, a spur of the Sierra Nevada, in the Sequoia National 

Forest and flow westward. At flood stages their waters reach the 

lower part of the valley immediately south of Tulare Lake; during 

the low-water season both streams sink into the sand near the foothills.

Several ranches divert a small amount of water from both streams 

for irrigation, but as the amount of tillable land is small, the agricultural products are sufficient only to supply the local demand.

On Deer Creek, in the vicinity of Hot Springs, hot sulphur water 

issues from several large springs which have become noted for their 

curative properties.

The gaging station, which is located half a mile below Hot Springs 

post office in the Sequoia National Forest, and about 2^ miles above 

the mouth of Tyler Creek, was established October 7, 1910.

The gage is a vertical staff fastened to a tree on the left bank of 

the stream, 100 feet above the highway bridge from which discharge 

measurements are made at high water.

The banks are.high and there is but one channel at all stages. The 

channel is composed of sand, gravel, and bowlders, and conditions 

favor good results.

This station is maintained in cooperation with the United States 

Forest Service.

No estimates of daily or monthly discharge have been prepared for 

1910.

The following discharge measurement was made by Stewart and 

Tompkins by wading 200 feet below gage:

October 7, 1910; width, 6.3 feet; area, 5 square feet; gage height, 0.39 foot; discharge, 2.2 second-feet.

TITLE RIVER BASIN.

GENERAL FEATURES.

Tule Kiver drains a small, somewhat rectangular area lying south 

of the Kaweah basin, west of the Kern basin, and north of the Deer 

Creek basin. Its length north and south averages about 25 miles 

and its width averages about 15 miles. The total drainage area 

above the rim of the valley is about 370 square miles.

Tule Kiver rises at an altitude of about 9,000 feet above sea level. 

The main stream is formed by the junction of North and Middle 

forks about 1 mile above Daunt post office and about 15 miles northeast of Portersville. It takes a southwesterly course to the point 

where it leaves the foothills about 5 miles east of Portersville, and 

has a length of about 30 miles. South Fork joins the main stream 

about 8 miles below Daunt. The flood water passes westward 

through old channels in the river's alluvial fan to Tulare Lake, which 

it enters south of Corcoran.

TULE RIVER NEAR PORTERSVILLE, CAL.

This station, which is located in the NW. i NW. i sec. 25, T. 21 S., 

K. 28 E., M. D. B. and M., 100 feet below the wagon bridge near 

McFarland's ranch, about 1 mile above the mouth of South Fork, 

about 8 miles east of Portersville, and about 9 miles below the junction of North and Middle forks, was established April 8, 1901.

A few small irrigation ditches divert water above the point of 

measurement. Below the station canals divert water for use chiefly 

in irrigating citrus fruits in the vicinity of Portersville. The acquired 

water rights exceed the minimum flow of the stream.

The staff gage is in two sections on the right bank. No change has 

ever been made in the gage datum.

Discharge measurements are made from the bridge about 100 feet 

above the gage.
70 SURFACE WATER SUPPLY, 1910, PART XI.

The channel is practically permanent and the velocity moderate. 

Conditions favor accuracy of discharge data. The 1910 rating 

curve is well defined and the record may be considered excellent.

SOUTH PORK OF TULE RIVER NEAR SUCCESS, CAL.

This station, which is located at the Indian school on the Tule 

Indian reservation, 7 miles southeast of Success, was established 

October 10, 1910.
SURFACE WATER SUPPLY, 1910, PART XI.

Rocky Creek enters about 2 miles above and the South Fork joins 

the main river about 10 miles below the gage. Thirteen small 

ditches, with an aggregate capacity of about 11 second-feet, divert 

water from the South Fork and tributaries above the station for irrigation -on the reservation. The South Tule ditch heads about 4 

miles below the station.

The gage is a vertical staff fastened to an alder on the left bank 

directly opposite the Indian school.

Discharge measurements are made by wading at medium and low 

stages. A--«ar and cable for high-stage measurements have not yet 

been installed.

The bed of the stream, which is composed of bowlders, is rough, 

and the course of the channel is probably permanent. The current is 

swift at medium and high stages. Both banks are high and wooded 

and not liable to overflow.

This station is maintained in cooperation with the United States 

Office of Indian Affairs.

No estimates of daily or monthly discharge have been prepared for 

1910.

The following discharge measurement was made by Stewart and 

Tompkins by wading about -J mile below gage:

October 11,1910: Width, 9 feet; area, 9 square feet; gage height, 0.33 feet; discharge, 

2.9 second-feet.

Daily gage height, in feet, of South Fork of Tule River near Success, Cal., for 1910.

KAWEAH RIVER BASIN. 

GENERAL FEATURES.

Kaweah River drains an area comprising about 715 square miles, 

lying on the western slope of the Sierra in the northern part of Tulare 

County, south and west of the Kings River basin, north of the Tule 

River basin, and west of the upper Kern River basin.

The main stream is formed 10 or 15 miles above the head of its delta 

by the confluence of East and Middle forks, which rise in numerous
FRANCISCO BAY DKA1NA&E BASINS.

small lakes nestling among high peaks on or near the divide, at an 

altitude of about 12,000 feet above sea level, and its course is southwestward throughout its length. Below the foothills it divides into 

several distributaries which cross the delta fan and enter Tulare Lake 

near Corcoran. Its total length above the delta is about 45 miles.

KAWEAH RIVER NEAR THREE RIVERS, CAL.

This station, which is located in the SE. £ sec. 27, T. 17 N., R. 28 E., 

M. D. B. and M., about 1 mile southwest of Three Rivers post office 

and about one-fourth mile back of J. O. Carter's ranch house on the 

wagon road from Lemon Cove to Three Rivers, about three-fourths of 

a mile below the mouth of the South Fork and 3 miles below the 

mouth of the North Fork was established April 29, 1903.

No important tributaries enter below the point of measurement.

Some water is diverted above the station for power, particularly on 

Middle and East forks, but it is returned to the stream above Three 

Rivers. A few small ditches divert water for local irrigation and 

domestic uses in the small valleys above Three Rivers. The acquired 

water-rights on this stream probably exceed low-water flow.

The staff gage, the datum of which has not been changed since the 

station was established, is in two sections.

Discharge measurements are made from a cable at the gage.

The conditions for obtaining accurate discharge data are fairly 

good. The stream is confined to its channel except at very high 

stages, when the right bank is overflowed somewhat. The bed, 

though composed of fine gravel and sand, is not subject to much 

change. The current is somewhat sluggish at very low stages and 

rather swift at high stages, though not excessively so.

The 1910 rating curve is well defined and the record may be considered good.

NORTH PORK OF KAWEAH RIVER AT KAWEAH, CAL.

This station, which is located at the highway bridge half a mile 

above Kaweah and about 2 miles above the mouth of the North 

Fork, was established October 12, 1910.

Sheep Creek enters 2| miles above and Manikin Creek one-fourth 

mile below the gage. Several small ditches divert water for irrigation above the station. The total amount of water used is estimated 

at about 20 second-feet.

The vertical staff gage is fastened to the right abutment of the 

bridge from which discharge measurements are made.

Both banks are high and wooded and not subject to overflow. 

The bed of the stream is bed rock and sand. At low water the current is sluggish at the bridge.

This station is maintained in cooperation with the United States 

Forest Service.

No estimates of daily or monthly discharge have been prepared 

for 1910.

KINGS RIVER BASIN. 

GENERAL FEATURES.

Kings River drains an area comprising about 1,840 square miles, 

lying on the western slope of the Sierra, south of the upper San 

Joaquin basin and north of Kaweah and upper Kern basins.

The main stream is formed well up in the mountains by the confluence of the North, Middle and South forks, which rise in numerous 

glacial lakelets nestling at the foot of glaciers and perpetual snow 

banks which protrude from the summits of high peaks on and near 

the crest of the Sierra. It flows south westward to the mouth of its 

canyon, about 10 miles northeast of Sanger, and across its delta fan 

to the trough of San Joaquin Valley, about 6 miles west of Lemoore. 

From this point most of the low-water flow passes northwestward 

through Kings Slough to San Joaquin River about 3 miles north of 

Mendota, but most of the flood flow passes southward to Tulare Lake. 

The total length of the river from its source to the mouth of its canyon is about 85 miles. Besides the three forks and their tributaries, 

the other principal tributaries are Dinkey and Big creeks from the 

north and Mill Creek from the south.

KINGS RIVER NEAR SANGER, CAL.

This station, which is located in the NW. I sec. 8, T. 13 S., R. 24 E., 

M. D. B. and M., just below a big bend in the river near the mouth of 

the canyon, about 15 miles northeast of Sanger and southwest of Red 

Mountain, was established September 3, 1895.

No tributaries enter below the station. Mill Creek enters from the 

south about 3 miles above the point of measurement. Big and 

Dinkey creeks enter from the north about 10 and 15 miles, respectively, above the station. The forks unite 20 or 25 miles above.

No water is diverted immediately above the place of measurement. 

Many miles above, however, a small quantity of water is diverted from 

tributary streams into a flume used for transporting lumber from the
SAN FRANCISCO BAY DRAINAGE BASINS. 77

mountains to Sanger. The total flow of the river at low and moderate stages is diverted into irrigation canals only a short distance 

below the station. The acquired water rights greatly exceed the 

low-water flow.

A Friez automatic water-stage register is used for obtaining gage 

heights at this station, because of the remarkable diurnal fluctuations 

of stage, especially during the spring and early summer when the snow 

is melting rapidly. Not uncommonly the weekly record sheet shows 

a notably regular sinusoidal curve indicating an hourly change and a 

daily range of nearly 2 feet. (See fig. 1.) No change has ever been 

made in the gage datum.

Discharge measurements are made from a cable about 500 feet 

below the gage.

FIGUBE 1. Gage-height record of Kings River near Sanger, Cal., May 22-29,1910.

The conditions for obtaining accurate discharge data at this station 

are very good. The stream is confined to its channel at all stages 

and the current is never too sluggish nor too swift. The channel has 

a gravel bottom but changes very little. The 1910 rating curve is 

well defined except at the lower stages and the record is excellent.

DINKEY CREEK NEAR OCKENDEN, CAL.

This station was established September 17, 1910, at the Dinkey 

ranger station in the Sierra National Forest, in sec. 20, T. 10 S., 

K. 26 E., M. D. B. and M., 9£ miles southeast of Ockenden.

Rock Creek enters 3 miles above and Bear Creek 1^ miles below 

the gage. A small unnamed tributary joins the stream at Dinkey 

Meadows 100 feet above the station.

The vertical staff gage is on the right bank about 400 feet below 

the ranger's station.

Discharge measurements are made by wading at low and medium 

stages. A car and cable for making gagings at high water will be 

installed.

There is but one channel at all stages as both banks are high. 

The bed of the stream is composed of gravel and small bowlders and 

the current is swift. Conditions are fairly satisfactory for making 

accurate measurements.

This station is maintained in cooperation with the United States 

Forest Service.

No gage heights were observed in 1910, and no estimates of daily 

or monthly discharge have been prepared.

RUSH CREEK NEAR OCKENDEN, CAL.

Rush Creek is tributary to Big Creek, which enters Kings River in 

T. 12 S., R. 25 E.

This station, which is located at Peterson's sawmill, about 3 miles 

southeast of Ockenden, in the Sierra National Forest, was established 

September 22, 1910.

Taylor Creek enters 1 mile above the gage. No water is at present 

diverted for irrigation.

The gage is a vertical staff fastened to a large cedar tree, on the right 

bank, 200 feet above the wagon bridge. At high stages discharge 

measurements are made from the bridge; at low stages by wading 

above the gage.

Both banks are high and wooded and not subject to overflow. The 

channel is composed of sand and will shift at high stages.

This station-is maintained in cooperation with the United States 

Forest Service.

No estimates of daily or monthly discharge have been prepared 

for 1910.

SAN FBANCISCO BAY DEAINAGE BASINS. 81

FEESNO EIVEE BASIN. 

GENERAL FEATURES.

Fresno Kiver rises on the west slope of the Sierra Nevada, in the 

Sierra National Forest, near the headwaters of the South Fork of 

Merced River, flows in general southwestward, but its waters reach 

the San Joaquin only during the high-water season. At other times 

the excess water not used for irrigation sinks in the sand of the river 

channel near Madera.

The principal tributaries, all small except during the rainy season, 

are Lewis Fork, North Fork, China, Crooks and Coarse Gold creeks 

in the foothills, and Willow Creek, which joins the main river below 

Madera.

Near the head of the river (locally known as Redwood Creek), is a 

grove of big trees (Sequoia gigantea) known as the Nelder or Fresno 

grove.

Water is diverted from the headwater streams to feed the Madera 

Sugar Pine Lumber Co.'s flume, which is used to float lumber to 

Madera. Irrigation ditches take water at an altitude of about 4,500 

feet, in the vicinity of Miami Mills, but only a small amount of water 

is used until the stream reaches the fertile valley land in the vicinity 

of Madera. A part of the flood waters could be stored by constructing 

a reservoir at Windy Gap near the mouth of Crooks Creek. The river 

below this point has considerable fall and power development is practicable.

FRESNO RIVER 1 NEAR FRESNO FLATS, CAL.

This station, which is located near the Salt Springs-Crane Valley 

highway bridge, in SE ^ sec. 36, T. 6 S., R. 21 E., Mount Diablo base 

and meridian, 1^ miles above the junction with Lewis Fork, and about 

4 miles northeast of Fresno Flats in the Sierra National Forest, was 

established September 23, 1910.

The station is below all important tributaries and above all diversions. Just above the bridge, water is diverted to a flume feeder of 

the Madera Sugar Pine Lumber Co.

The gage is a vertical staff fastened to an alder on the left bank 

about 400 feet above the bridge. Discharge measurements are made 

by wading.

There is but one channel at all stages as both banks are high: The 

bed of the stream is sandy and will shift at high stages.

This station is maintained in cooperation with the United States 

Forest Service.

No estimates of daily or monthly discharge have been prepared 

for 1910.

NORTH FORK OF FRESNO RIVER, * NEAR SUGAR PINE, CAL.

This station was established September 26, 1910, at the old mill at 

the Miami forest ranger's camp 3 miles southwest of Sugar Pine 

and 35 miles northwest of Raymond.

The gage is a vertical staff fastened to an alder on the left bank 

about 200 feet north of the ranger's station.

Discharge measurements are made by wading.

The stream bed, which is composed of sand and small bowlders, 

is smooth. Both banks are high and wooded and will not overflow.

No gage heights were observed during 1910 and no estimates of 

daily or monthly discharge have been prepared. .

MERCED RIVER BASIN. 

GENERAL FEATURES.

The drainage basin of Merced River lies on the western slope of 

the Sierra, north of the upper San Joaquin basin and south of the 

Tuolumne basin. It does not extend so far east as the other two 

basins, and it touches the Sierra divide in only one point Mount

i Known locally as Miami Creek.
SAN FRANCISCO BAY DRAINAGE BASINS. 83

Lyell (elevation, 13,090 feet) which is common to the three basins. 

The mountainous part of the basin lies almost wholly in Mariposa 

County; the foothill and valley parts are in Merced County. The 

basin is about 65 miles long from the rim of the valley to the crest and 

20 to 25 miles wide, and its total area above the valley border is about 

1,200 square miles.

Merced River has its source in numerous small glacial lakes in the 

region about Mount Lyell and flows southwestward to its junction 

with the lower San Joaquin, about 5 miles northeast of Newman. 

It has a total length of about 135 miles, two-thirds of which is in 

the mountains. Its chief tributaries are Tenaya and Yosemite 

creeks from the north and Illilouette and Bridal Veil creeks and 

South Fork from the south.

MERCED RIVER NEAR MERCED FALLS, CAL.

This station, which is located in the NW. lsec.ll,T.5S.,R.15E.., 

M. D. B. and M., about 1 \ miles east of Merced Falls, was established 

April 6, 1901.

No important tributaries enter for 25 miles above or below the 

station.

The water diverted for power development above the station 

returns to the river. Below Merced Falls, however, the combined 

capacity of irrigating canals in the vicinity of Snelling exceeds the 

low-water flow. All acquired water rights above Merced Falls are 

for power or mining development.

The staff gage, the datum of which has not been changed since the 

station was established, is in several sections on the right bank.

Discharge measurements are made from a cable near the gage.

The flow at the station is doubtless somewhat affected at times by 

artificial regulation at some of the power dams, several miles above? 

but pondage from the dam at Merced Falls probably has no appreciable effect at the station. The bed of the stream at the station is 

composed of gravel, and is subject to some changes at high water. 

The velocity is also very great at flood stages.

The 1909 rating table, which is well defined, has been used for 

1910. The record is excellent.

SOUTH FORE OF MERCED RIVER AT WAWONA, CAL.

This station was established December 15, 1910, at the upper foot 

bridge, opposite the United States military camp 1 mile below 

Wawona, in the SE. J sec. 33, T. 4 S., R. 21 E., M. D. B. and M., 

in the Sierra National Forest.

Big Creek enters one-fourth mile above and Rush Creek threefourths mile below the station. The ranch of the Wawona Co. at 

Wawona is irrigated from a tributary of the South Fork.

The gage is a vertical staff fastened to the center pier of the footbridge. At low and medium stages discharge measurements are made 

by wading below the bridge; a car and cable will be installed for 

high-stage measurements.

The channel, which is composed of gravel and small boulders, is 

straight for some distance above and below the station. The left 

bank is high; the right bank is more sloping. There is but one 

channel at all stages.

This station is maintained in cooperation with the United States 

Forest Service.

No estimates of daily or monthly discharge have been prepared 

for 1910.

BIG CREEK NEAR WAWONA, CAL.

This station, which is located at the highway bridge on the old 

Madera-Yosemite toll road at Summerdale (an abandoned post 

office), in sec. 23, T. 5 S., R. 21 E., 4 miles south of Wawona, was 

established September 25, 1910.

Several miles above the station water is diverted from Rush Creek, 

the principal tributary of Big Creek, for use in the flume of the 

Madera Sugar Pine Co. for floating lumber from Sugar Pine to Madera.

The gage is a vertical staff fastened to the downstream end of the 

left abutment of the bridge.

At high stages discharge measurements are made from the bridge.

No gage heights were observed during 1910 and no estimates of 

daily or monthly discharge have been prepared.

This station is maintained in cooperation with the United States 

Forest Service.

TUOLUMNE EIVER BASIN. 

GENERAL FEATURES.

Tuolumne River drains an area on the western slope of the Sierra, 

north of the Merced basin and south of the Stanislaus basin. For a 

distance of about 50 miles the Sierra divide separates this basin from 

Mono Lake and Walker River basins to the east. The length of the 

basin is about 105 miles, two-thirds of which is in the mountains. 

The total area of the mountainous part of the drainage basin is about 

1,680 square miles almost wholly in Tuolumne County.
U. S. GEOLOGICAL SURVEY

A TUOLUMNE RIVER NEAR MOUTH OF CONNESS CREEK.

WATER-SUPPLY PAPER 291 PLATE III

B. FALLS OF RANCHERIA CREEK, HETCH HETCHY VALLEY.

SAN FRANCISCO BAY DEAINAGE BASINS. 87

The Tuolumne rises in numerous glacial lakes on or near the Sierra 

divide, and flows south westward to its junction with the San Joaquin, 

10 miles west of Modesto. Its principal headwaters come from the 

glacier and lakes on the northern slope of Mount Lyell to the north 

and east of the headwaters of Merced River. The course of the river 

is through beautiful upland meadows in its upper part, then through 

a canyon nearly 80 miles long, which has been cut out of solid granite. 

The upper part of this canyon, for a distance of about 25 miles, is 

from 3,000 to 4,000 feet deep, and is known as the Grand Canyon of 

the Tuolumne. At the lower end of the Grand Canyon is Hetch 

Hetchy Valley, which is smaller than Yosemite Valley, but in every 

other way resembles it very much. (See PI. III.) Finally, the river 

passes through the lower canyon into the San Joaquin Valley, which 

it enters near Lagrange. Its total length is about 150 miles.

Nearly all the tributaries of Tuolumne River enter from the north. 

In order from east to west, the principal ones are Return, Rancheria, 

Falls, and Cherry creeks, Clavey River, North Fork of Tuolumne 

River, and Woods Creek. Eleanor Creek is tributary to Cherry 

Creek. South Fork of Tuolumne River is tributary to the main 

stream from the south. Middle Fork is tributary to South Fork.

TUOLUMNE RIVER NEAR LAGRANGE, CAL.

This station was established August 29, 1895, at the wagon bridge 

at Lagrange, about 2 miles below the Lagrange dam and headworks 

of Turlock and Modesto canals, and half a mile below the power house 

of the Lagrange Water & Power Co. in NW. % sec. 20, T. 3 S., R. 14 

E., M. D. M. Since April 1, 1908, the station has been maintained 

at the dam in SE. \ sec. 17 T. 3 S., R. 14 E., M. D. M., and flow 

has been determined by considering the dam as a weir.

Woods Creek unites with the main stream from the north about 20 

miles above Lagrange. No other tributaries of importance enter 

near the station.

Three important diversion systems take water from Tuolumne 

River above Lagrange: The Turlock and Modesto canals take water 

at Lagrange dam from the left and right banks, respectively, for 

irrigation in the San Joaquin Valley. The Lagrange Water & 

Power Co.'s canal takes water from the left bank about 17 miles 

above Lagrange. The diverted water is used chiefly for power 

development and all water so used is returned to the river below 

the dam. Water rights already acquired on this stream are considerably in excess of the low-water flow. It is practically impossible 

to determine the minimum flow of the stream very closely because of 

the diversions. During the late summer and fall the power and irrigation canals take the total flow and no water passes over the dam 

for several months at a time. Regular stations are maintained on
88 SURFACE WATER, SUPPLY, 1910, PART XI.

the three canals, but the minimum flow is appreciably affected by 

water that seeps around and through the dam and from the canals.

The gage is painted on a rock ledge on the right bank, 80 feet above 

the dam. The zero of the gage is at the average elevation of the crest 

of the dam. The gage at the original station is a vertical staff on the 

pier of the bridge from which occasional discharge measurements are 

made for checking the rating of the dam. The original datum of this 

gage is still maintained.

In general, conditions for obtaining accurate discharge data at 

Lagrange dam are very good, andj, except for minimum flow, full 

reliance can be placed on the records at this station.

MODESTO CANAL NEAR LAGRANGE, CAL.

The Modesto canal, which diverts water from the right bank of 

Tuolumne River, is owned by the Modesto irrigation district. The 

water is taken through a concrete bulkhead at the end of Lagrange 

dam and is used for irrigating 81,200 acres of land around Modesto 

in Stanislaus County. The district has filed on 640 second-feet, but 

the maximum capacity of the canal at present is less than 600 secondfeet.

The principal part of the construction work on this canal was done 

prior to 1892, but on account of litigation the canal was not finished 

until April, 1903. A gage-height record has been kept since April 26, 

1903, when a gage was installed in Indian Hill flume, near Lagrange, 

Cal. On July 12, 1904, the station was moved to the flume near the 

intake, in SE. J sec. 17, T. 3 S., R. 14 E., M. D. M., in order that 

more gage readings could be made and their fluctuations better interpreted. The gage is an iron staff in a concrete well about 50 feet 

below the waste gates. Measurements are made from a footbridge 

at a concrete section about 500 feet below the headworks.

This station is well rated and the record is excellent.

TTTRLOCK CANAL NEAR LAGRANGE, CAL.

The Turlock canal, which is owned by the Turlock irrigation district, diverts water through a short tunnel from the left bank of Tuolumne River. The head gates are only a few feet above Lagrange 

dam. The diverted water is used for irrigating 176,000 acres of fertile land in the vicinity of Turlock and Ceres in Stanislaus County. 

The district has filed on 1,500 second-feet, but the maximum capacity 

of the canal at present is somewhat less than 1,000 second-feet.

The first water was turned into the canal in small quantities in 1898 

and was used for puddling. A record of the gage height has been 

kept from July, 1899, to the present time. The gage is a staff float 

in a concrete well a few feet below the waste gates. The gage is 

located at the head of the canal of the Turlock irrigation district, in 

the SW. \ sec. 16, T. 3 S., R. 14 E., M. D. B. and M. Measurements 

are made in a board flume about half a mile below the gage well.

The 1910 rating curve is well defined and the record is excellent.

Canal, and Modesto Canal, but do not include the flow in the power canal.

LAGRANGE WATER & POWER CO.'S CANAL NEAR LAGRANGE, CAL.

The Lagrange Water & Power Co.'s canal takes water from the 

south side of Tuolumne River at Indian Bar, about 17 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 it 

is now locally known as the "old mining ditch." Recently it has 

been thoroughly repaired and is now used as a supply canal for the 

new hydro-electric plant which was installed in the latter part of 1907. 

The power house is situated on the bank of the river about half a 

mile above the town of Lagrange and is below the dam and headworks of the Turlock and Modesto irrigation canals. Gage heights 

are depths of water in the flume.

No discharge measurements were made in 1910,

STANISLAUS RIVER BASIN. 

GENERAL FEATURES.

Stanislaus River drains a long, narrow basin lying on the western 

slope of the Sierra, north of the Tuolumne basin, south of the Calaveras and Mokelumne basins, and west of the Walker, River basin, 

from which it is separated for a distance of about 25 miles by the 

Sierra divide. The length of the basin from the valley rim to the 

crest of the divide is about 75 miles; its width averages about 12 

miles in the foothills and less than 25 miles near the eastern border. 

North Fork above and the main stream below form the boundary 

between Calaveras and Tuolumne counties. The total drainage area 

above the valley is about 950 square miles.

Stanislaus River has its source in small glacial lakes and on high 

peaks of the Sierra divide, and flows southwestward to its junction 

with the lower San Joaquin about 15 miles west of Modesto. It has a 

total length of about 120 miles, of which about 80 miles is in the 

mountains and 40 miles in the valley. The main stream is formed 

by the confluence of its three principal forks heading well back in the 

mountains. Middle Fork, the largest and most important, unites 

with North Fork about 12 miles north of Sonora and 30 or 35 miles 

above the valley rim; South Fork joins the main stream about 8 

miles below the junction of North and Middle forks.

STANISLAUS RIVER AT KNIGHTS FERRY, CAL.

A gaging station was established on Stanislaus River May 3, 1895, 

at the railroad bridge half a mile north of Oakdale. On July 30, 1898; 

a cable was placed about 1,000 feet below the railroad bridge, and the 

station was maintained at this point until February 16, 1901, when 

it was discontinued.
102 SUEFACE WATEB SUPPLY, 1910, PART XI.

The present station, which is located in the NE. £ sec. 29, T. 1 S., 

K. 12 E., M. D. B. and M., at Knights Ferry, about 12 miles northeast of Oakdale, was established May 19, 1903.

No important tributaries enter below the station or for many miles 

above. South Fork joins the main stream about 25 miles above the 

station.

 Numerous ditches divert water from Stanislaus River for mining 

operations, but most of the water is returned to the river. Some 

water, however, is diverted from the South Fork and turned into the 

Tuolumne basin. Water which is not returned to Stanislaus River is 

also diverted from North Fork for use in the vicinity of Murphy and 

Angels.

The Stanislaus Water Co. diverts water about 3 miles above 

Knights Ferry for power development and also for irrigating land 

between Knights Ferry and Stockton. The amount used for power 

is returned to the river through the power house about 1,000 feet 

above the gaging station. The developed and acquired water rights 

probably exceed the low-water flow of the stream.

The staff gage, the datum of which has not been changed since the 

station was established, is in several sections on the right bank.

Discharge measurements are made from a cable 25 feet above the

The conditions for obtaining accurate discharge data at this station 

are not the best, on account of excessive velocities at high stages and 

changing conditions of control at low and moderate stages. About 

800 feet above the station the stream is divided into two channels by 

an island, and a low dam spans each channel at the head of the island. 

On the right bank below one of these dams is a power house which 

operates with water taken from behind the dam, and also from the ditch 

heading about 3 miles above. The tail water returns to the river, 

and varies with the load at different hours of the day, thus affecting 

the gage height somewhat at low stages. The channel section at the 

station is also subject to slight change, and both banks overflow to 

some extent in high floods.

The 1910 rating curve is well defined and the record is good.

STANISLAUS WATER CO.'S CANAL NEAR KNIGHTS FERRY, CAL.

This canal diverts water from the right bank of Stanislaus River 

at a point about 3 miles above Knights Ferry. At some distance 

below the intake the Schell ditch diverts a small quantity of water 

from the main canal for irrigation. The flow in the ditch, as determined by measurement in 1909, is about 6 second-feet and is assumed 

to be constant. About half a mile above Knights Ferry is another 

diversion from the main canal through a pressure pipe to the power 

house on the bank of the river, and the water thus diverted is used 

for power and then returned to the river about 1,000 feet above 

the gaging station.

The gagijig station, which is on the main canal below all diversions, is on the Oakdale road about one-half mile from Knights 

Ferry and about 200 feet below the point where the canal passes 

under the flume of Schell ditch, in the NW. J sec. 29, T. 1 S., R. 

12 E., M. D. B. and M. It was established June 11, 1904.

The gage is a vertical staff on the left bank at a private bridge 

across the canal about 20 feet below the foot bridge from which discharge measurements are made.

The rating curve for 1910 is well defined and the record is excellent.

ROSE CREEK NEAR JUPITER, CAL.

This station, which is located just above the bridge at the trail 

crossing, about 2 miles northwest of Jupiter, in the SE. J sec. 17, 

T. 3 N., K. 15 E., M. D. B. and M., was established September 8, 

1910,

Eagle Creek enters 1J miles above and Knight Creek 2£ miles 

below the station. The area drained by Kose Creek is rough and is 

covered chiefly with brush with some merchantable timber.

The gage is a vertical staff fastened to a tree on the right bank, 

100 feet above the bridge.

Discharge measurements are made by wading near the gage.

The channel is composed of gravel and small bowlders and the 

current is swift. At low and medium stages the stream is confined 

to one channel. At extreme high water the left bank is overflowed 

and a second channel is formed.

This station is maintained in cooperation with the United States 

Forest Service.

No estimates of daily or monthly discharge have been prepared for 

1910.

SAN FRANCISCO BAY DRAINAGE BASINS. 109

SOUTH FORK OF STANISLAUS RIVER NEAR COLUMBIA, CAL.

This station, which is located at the highway bridge at Italian Bar, 

in the SE. £ sec. 33, T. 3 N., R. 15 E., M. D. B. and M., about 5 miles 

northeast of Columbia, was established September 6, 1910.

Deer Creek enters about 4J miles above and Fivemile Creek 1^ 

miles below the gage. About 11 miles above the station water is 

diverted for domestic use at Sonora and Tuolumne. The low-water 

flow at the station is controlled by storage.

The gage is a vertical staff fastened to the middle pier of the bridge.

Discharge measurements at low and medium stages are made by 

wading about 200 feet below the gage. At high stages fair measurements can be made from the bridge.

The banks are high and wooded and not subject to overflow. The 

channel is composed of gravel, bed rock, and bowlders and appears 

permanent.

This station is maintained in cooperation with the United States 

Forest Service.

No estimates of daily or monthly discharge have been prepared for 

1910.

110 SURFACE WATER SUPPLY, 1910, PART XI.

CALAVEEAS RIVER BASIN. 

CALAVERAS RIVER AT JENNY LIND, CAL.

Calaveras River drains an area on the western slope of the Sierra, 

north of the Stanislaus basin and south of the Mokelumne basin. 

The total area of this basin above the border of San Joaquin Valley 

is about 500 square miles.

Calaveras River is formed by the confluence of its North and South 

forks near San Andreas, and flows southwestward to its junction with 

the lower San Joaquin, a few miles west of Stockton. Its total length 

is about 80 miles, of which 35 miles are in the valley and 45 miles in 

the mountains.

The basin is almost wholly a foothill region. The hills are low, 

and here and there they are separated by small, irregular valleys. 

The highest point in the basin is 6,000 feet in altitude, but only a very 

small part exceeds 4,000 feet.

The gaging station, which is located at the wagon bridge on the 

Milton road, about one-fourth mile from Jenny Lind post office, in 

the SE. i sec. 22, T. 3 N., R. 10 E., M. D. B. and M., was established 

December 1,1906, by the United States Weather Bureau, and has been 

rated by the Geologic al Survey. The records are of greatest immediate 

value in devising protective measures against the flooding of the city 

of Stockton during the winter.

The station is well up in the foothills, and there are a few small 

intermittent tributaries below. Cosgrove, Slate, and Bear creeks 

enter about 5 miles above the station. North and South forks unite 

about 15 miles above.

No water is diverted immediately above the station. The acquired 

water rights are for mining and power operations.

The gage, the datum of which has not been changed since the station was established, is a vertical staff in two sections on the right 

bank.

Discharge measurements are made from the bridge near the gage.

The conditions for obtaining accurate discharge data are not very 

good. At low stages the stream at the station is about 100 feet wide 

and 2 feet deep, and the current is very sluggish. A considerable 

change in flow makes very little difference in the gage height, so that 

more or less error arises from the fact that the gage record is only to 

tenths of feet. At low stages measurements can be made at other 

sections by wading, thus eliminating inaccuracies from that source. 

At flood stages the current is very swift and the channel, which is 

composed of gravel and cobblestones, shifts slightly.

The 1910 rating curve is well defined and the record is fairly 

satisfactory.
SAN FRANCISCO BAY DRAINAGE BASINS. Ill

NOTE. Daily discharge determined from a rating curve fairly well denned. Discharge estimated June 

2 to 24 and July 6 to 13. Channel probably dry during the greater part of August and September. There 

was probably little change in conditions of flow during October.

SAN FRANCISCO BAY DRAINAGE BASINS. " 113

MOKELUMNE RIVER BASIN. 

GENERAL FEATURES.

The Mokelumne River basin lies on the western slope of the Sierra, 

north of the Calaveras and Stanislaus River basins, and south of 

American River basin. Strictly speaking the area drained by Cosumnes River, and several other small tributaries which enter many 

miles west of the valley border, should be considered as a part of the 

Mokelumne basin, but this area contributes nothing to the flow of 

Mokelumne River above the lower Sacramento and San Joaquin 

delta region. The total area of the basin above the valley rim, 

exclusive of that drained by the Cosumnes, is about 640 square miles.

The Mokelumne rises in glacial lakelets in Alpine County at an 

altitude of nearly 10,000 feet above sea level, and flows southwestward to its junction with the lower San Joaquin, about 25 miles 

northwest of Stockton. It has a total length of about 140 miles, of 

which approximately 90 miles are in the mountains. For the greater 

part of its course it forms a boundary between Amador County on 

the north and Calaveras County on the south. The principal 

branches are North, Middle, and South forks, which unite about 

5 miles above Electra and nearly 40 miles above the rim of the 

valley. Bear River is tributary to North Fork from the north.

MOKELUMNE RIVER NEAR CLEMENTS, CAL.

This station, which is located at the highway bridge about 1 mile 

north of Clements, in the NW. J sec. 15, T. 4 N., R. 8 E., M. D. B. 

and M., was established October 28, 1904.

No important tributaries enter for many miles above or below the 

station. The three forks unite about 30 miles above Clements, and 

Cosumnes River enters from the north about 30 miles below Clements.

Several ditches take water for use in mining and in power development in the Mokelumne basin, but most of the water is returned to 

the river. No water is diverted immediately above the station, 

except for local irrigation on the bottom lands adjacent to the river. 

In the upper part of the basin some water is probably diverted into 

contiguous basins. The acquired water rights on the lower part of 

the stream probably take the larger part, if not all, of the minimum 

flow.

The low-water section of the gage is an inclined staff, the upper 

portion is painted on the pier near the right end of the bridge. No 

change has ever been made in the gage datum.

Discharge measurements are made from the bridge.

114 SURFACE WATER SUPPLY, 1910, PART XI.

The channel, which is composed of sand and gravel, is subject to 

slight changes during high water. The 1910 rating curve is well 

defined and the record is good.

116 SUKPACE WATER SUPPLY, 1910, PAET XI.

COSUMNES RIVER AT MICHIGAN BAR, CAL.

Cosumnes River rises on the western slope of the Sierra at an 

altitude of 7,700 feet, and flows southwestward to its junction with 

the Mokelumne, about 6 miles east of Walnut Grove. Its total 

length is about 90 miles. The main stream is formed by the confluence of its three forks, about 45 miles above its mouth and 20 miles 

above the valley border.

The gaging station, which is located at the Michigan JBar bridge, 

about 8 miles southwest of Latrobe and not far from the Michigan 

Bar post office, in the NW. \ SE. \ sec. 36, T. 8 N., R. 8 E., M. D. 

B. and M., was established October 29, 1907.

No tributaries enter below the station. Big Canyon Cr,eek joins 

the main stream from the north about 6 miles above Michigan Bar, 

and the junction of the three forks is about 14 miles above.

Some water is diverted from the south side of the stream above 

the station and used for hydraulic mining near Michigan Bar. It is 

probable that all acquired water rights are for mining operations. 

Some water is also diverted from North Fork basin to the South 

Fork of American River.

The gage, the datum of which has not been changed since the 

station was established, is a vertical staff on the middle pier of the 

bridge.

Discharge measurements are made from the bridge.

The river bed is composed of sand and gravel and is subject to 

slight changes. At low stages the current is sluggish at the bridge. 

Very satisfactory measurements may be made at medium and high 

stages. No measurements have been made on the diversion ditch. 

The drainage area above the station is 524 square miles.

SACRAMENTO RIVER SYSTEM. 

GENERAL FEATURES.

The mountain torrent that forms the head of Sacramento River 

issues from a small lake, unnamed on the map, lying 6,600 feet above 

sea level, on Mount Eddy, one of the peaks of the Trinity Mountains. 

About 8 miles east of this lake, or 12 miles following the course of the 

stream, it receives Wagon Valley Creek, which is fed by springs emerging from the lava beds at the southwest base of Mount Shasta, springs 

that are frequently referred to as the source of the Sacramento. 

About 370 miles south of its junction with Wagon Valley Creek the 

river unites with the San Joaquin and enters Suisun Bay, 50 miles 

from San Francisco.

The river is joined by numerous tributaries from the east and west. 

Those coming from the Sierra Nevada flow almost southwest; those 

from the Coast Range flow in a general easterly direction. The broad 

western slope of the Sierra furnishes by far the larger part of the 

drainage and all the important tributaries. Few of the streams from 

the Coast Range reach the Sacramento directly but become lost u in 

the intricate plexus of sloughs which meander through the tule lands 

bordering the main river. Oil the east, also, only the larger tributaries reach the Sacramento by a definite channel, and often that becomes exceedingly tortuous." *

Of the total fall of the river 6,600 feet from source to sea level 

5,913 feet occurs in the 56 miles above the mouth of Pit River and 447 

feet more in the 67 miles between Pit River and Red Bluff, leaving 

only 240 feet of fall for the remaining 250 miles of course.

Above the mouth of Pit River the Sacramento is a comparatively 

small stream, flowing swiftly in a well-defined channel; below the

» Ransome, F. L., The Great Valley of California: Bull. Univ. California, vol. 1,1893-1896, p. 379.
SAN FBANCISCO BAY DRAINAGE BASINS. 119

Pit its magnitude increases, and at Red Bluff, where it enters Sacramento Valley, it becomes a sluggish stream, of small slope and small 

capacity. It is navigable to Red Bluff, 250 miles above its mouth.

Below the mouth of Stony Creek, for about 100 miles of its 

lower course, the Sacramento occupies a ridge 5 to 20 feet higher than 

the troughs of the nearly parallel flood basins on each side, which are 

2 to 7 miles from the river. The channel capacity throughout this 

distance is less than one-third that necessary to carry ordinary floods. 

The levees that have been constructed to lessen or prevent overflow 

all fail at one or more places during extreme floods and some fail during ordinary floods. A large amount of water may thus pass from the 

river into the flood basins and be stored for a time, thus reducing the 

maximum rate of flow of the Sacramento and increasing the flood 

period.

The large overflow area on the west side of the Sacramento is 

divided into two basins Colusa basin on the north and Yolo basin on 

the south by a ridge of detritus brought down by Cache Creek. The 

flood area on the east side of the river is divided into four basins 

(called, from north to south, Butte, Sutter, American, and Sacramento) by Marysville Buttes and Feather and American rivers. 

The total area of these big flood basins is approximately 900 square 

miles and their combined storage capacity is equivalent to three days' 

continuous flood flow of all the streams discharging into the valley. 

When full these basins hold sufficient water to cover the entire valley 

to a depth of 1.38 feet.

SACRAMENTO RIVER AT CAS.TELLA, CAL.

This station, which is located at the private highway bridge at 

Castella, in sec. 22, T. 38 N., R. 4 W., M. D. B. and M., was established 

October 15, 1910. Castle Creek enters the river about one-half mile 

above the station.

The gage is a vertical staff on the downstream end of the right 

abutment of the private highway bridge from which discharge measurements are made.

No estimates of daily or monthly discharge have been prepared for 

1910.

The following discharge measurement* was made by W. V. Hardy 

from the highway bridge:

Octobers, 1910: Width, 75 feet; area, 106 square feet; discharge, 190 second-feet.

1 Gage not in position when measurement was made.

This station, which is located at the highway bridge at Antler, 

200 feet above the mouth of Gregory Creek, in S. E. J sec. 13, T. 35 

N., R. 5 W., about 22 miles below the gaging station at Castella, was 

established November 19, 1910.

Middle Salt Creek enters the Sacramento about 2 miles above and 

Salt Creek about 3 miles below the station. Pit River, the main tributary of the upper Sacramento, enters about 14 miles below Antler.

The gage is a vertical staff on the downstream end of the pier at 

the right end of the bridge.

Discharge measurements are made from the bridge.

No estimates of daily or monthly discharge have been prepared for 

1910.

SAN FRANCISCO BAY DRAINAGE BASINS. 121 

SACRAMENTO RIVER NEAR RED BLUFF, CAL.

This station, which was established January 28, 1902, to take the 

place of the gaging station maintained at Jellys Ferry since April 30, 

1895, is located in lot 4, sec. 34, T. 28 N., R. 3 W., at the lower end 

of Iron Canyon, 4 miles above Red Bluff and about 3 miles, by river, 

below the proposed Iron Canyon dam site, at the location used for 

stream gaging by the State engineer in 1879, and by the commissioner of public works in 1893 to 1894. Discharge measurements 

were made in 1901 before the station was regularly established.

The river at this point is straight for 2 or 3 miles. The width 

between the banks at low water is about 500 feet. The depth of 

water at low stages averages 6 feet, with a maximum depth of 9 feet. 

The banks are steep and firm. The river flows in a bed of coarse 

gravel and cobblestones, with here and there small bowlders. The 

bedrock is lava.

Discharge measurements are made from a car and cable (830 feet 

span), 30 feet above the gage.

No important tributaries enter within several miles of the station, 

above or below. Antelope and Redbank creeks come in about 7 miles 

and Mill Creek about 16 miles below the station. Paines Creek 

enters about 3 miles and Battle and Cottonwood creeks about 10 

miles above the station. Pit River enters about 40 miles above and 

Feather River about 100 miles below.

No diversions of any kind are made above the station, and it is 

believed that no appropriations of nor filings on water have been 

made.

The flow at the station is not affected by artificial storage.

The gage used by the commissioner of public works was still in 

place at the cable site and was used from January 28, 1902, the 

date upon which observations were begun, until December 31, 1903. 

A second gage was placed on the right bank, 3,200 feet below the 

cable, January 1, 1904, as no observer could be obtained to continue 

readings, at the cable gage, and it was read until September 28, 1904. 

On this date the gage was removed to the left bank about 4,000 feet 

below the gaging station and read until February 12, 1906. Since 

February 14, 1906, the cable gage has been read. By synchronous 

readings of the lower gage with that at the cable, all readings have 

been reduced to equivalent readings for the cable gage. The datum 

of the cable gage which is read twice a day has remained unchanged.

The rating curve now in use is applicable since the station was 

established. The record is considered excellent.

PIT RIVER BASIN. 

GENERAL FEATURES.

Pit River drains an area in the northeastern part of California, 

chiefly in Modoc, Lassen, and Shasta counties. The river is formed 

by the union of its North and South forks. The South Fork rises 

on the western slope of the Warner Mountains about halfway between 

Warren and Eagle mountains, at an altitude of 8,000 feet above sea 

level, flows southwestward 10 miles, passing through Eagle Lake, 

then westward about 10 miles, then turns abruptly and flows northward through a swampy valley to Alturas, where it is joined by the 

North Fork, which rises about half a mile south of Goose Lake and 

flows irregularly southward about 16 miles to the junction. The 

length of South Fork above the junction is about 36 miles, in which 

distance it falls 3,550 feet; 3,400 feet of this fall is made in the first 

15 miles.
124 SURFACE WATER, SUPPLY, 1910, PART XI.

Topographically the basin of the North Fork includes the area 

tributary to Goose Lake and is therefore larger than the basin of the 

South Fork. Goose Lake is an alkaline water body, 28 miles long 

and 10 miles in maximum width, lying about two-thirds in California 

and one-third in Oregon. It is fed by 16 streams in California with 

an aggregate drainage area of 250 square miles, by annual rainfall 

on the open surface of the lake (estimated at 14 inches), by 6 streams 

in Oregon, and probably also by subsurface springs. Normally the 

lake does not overflow, but for a short time in 1869 it sent a stream 

southward to the North Fork of the Pit, and it is reported to have 

overflowed to Pit River in 1881 for more than two hours during a 

severe storm from the north. The lower end of the lake is bordered 

by lava beds through which some water may be lost by percolation. 

Drews Creek, Cottonwood Creek, and Thomas Creek, the principal 

streams flowing into Goose Lake, drain the southeast slope of a high, 

timbered ridge near tne southern corner of Lake County.

Below Alturas the Pit flows, in general, southwestward to its junction with the upper Sacramento about 12 miles north of Redding.

At Alturas the Pit is 4,500 feet above sea level; at its mouth it is 

687 feet; the total fall below the fork is therefore 3,818 feet.

Below the forks the principal tributaries are McCloud River, Squaw 

Creek, and Fall River from the north, and Burney, Hat, Beaver, Ash, 

and West Valley creeks from the south. McCloud and Fall rivers 

are the largest, having a minimum flow of 1,200 to 1,500 second-feet. 

Hat and Burney creeks also have a minimum flow of several hundred 

second-feet.

PIT RIVER AT HENDERSON, CAL.

This station, which is located at the ferry, one-third mile above 

Henderson, in sec. 36, T. 37 N., R. 1 W., was established September 

28, 1910.

Nelson Creek enters the river about 1 mile above the station, and 

Kosk Creek about 1 mile below.

The gage is a vertical staff attached to an alder on the left bank. 

Discharge measurements are made from a cable 95 feet below the 

gage.

No estimates of daily or monthly discharge have been prepared for 

1910.

PIT RIVER NEAR YDALPOM, CAL.

This station which is located at Silverthorne Ferry, in sec. 32, T. 34 

N., R. 3 W., about If miles below Ydalpom, about 1 mile below the 

mouth of Squaw Creek, about 5 miles above the mouth of McCloud 

River, and 7 miles above the junction with the Sacramento, was 

established November 16, 1910. By combining these data with the 

record on the McCloud at Baird, the total flow of Pit River may be 

determined.

The gage is a vertical staff on an ash tree on the left bank near the 

ferry.

Discharge measurements are made from a boat a short distance 

above the ferry cable.

No estimates of daily or monthly discharge have been prepared

126 SURFACE WATER SUPPLY, 1910, PART XI. 

GOOSE LAKE BASIN.

COTTONWOOD CREEK NEAR LAKEVIEW, OREGON.

Cottonwood Creek is tributary to Goose Lake. This station, 

which is located at a site for a storage dam in sec. 29, T. 38 S., K. 19 E., 

about 10 miles west of Lakeview, was established November 22, 1908. 

A dam at this site will store about 30,000 acre-feet of water and in 

connection with the proposed dam on Drews Creek will afford water 

sufficient to irrigate about 60,000 acres of land.

A 10-foot Cippoletti weir was installed at the dam site in November, 

1908, and a gage was placed above it to measure the head. On 

January 19, 1909, the weir was lengthened to 15 feet, a footbridge 

was installed about 1,000 feet below it, and an inclined gage was set 

on the left bank. Measurements were made by a current meter from 

the bridge, as the weir had been so damaged by a flood that the abutments leaked. The damage was, however, repaired and comparative readings on both gages were made during most of 1909.

A small channel to the right of the measuring section caTries water 

at high gtages; both banks are woodsd and are overflowed at flood 

times. The channel at the lower station is evidently permanent1 and 

a good discharge rating curve has been developed. As far as available the records derived from observations of the lower gage have 

been used in constructing the curve. The weir records used for the 

earlier period are somewhat uncertain, as the weir may have leaked.

The relation between gage height and discharge is affected by ice 

during extremely cold weather but evidently only for short periods, 

so that the accuracy of the determinations of the yearly run-off is not 

materially impaired.

The creek shows large, diurnal fluctuations during the spring, and, 

as the gage has been read only once or twice daily, the records for the 

spring season are subject to considerable error.

The station is maintained in cooperation with the Oregon Valley 

Land Co., which has furnished the weir data and gage heights.

DREWS CREEK NEAR LAKEVIEW, OREGON.

Drews Creek is tributary to Goose Lake. This station, which is 

located at a highway bridge below the proposed dam site of the Oregon 

Valley Land Co., about 23 miles west of Lakeview, in sec. 5, T. 40 S., 

K. 18 E., was established March 1, 1910. The point is below all 

important tributaries and is designated as station No. 3, as two other 

sites near by had previously been used. Station No. 1, located at the 

dam site, was established January 16, 1909. The gage was an inclined 

staff and discharge measurements were made from a footbridge 

near by. This gage was read until May 31, 1909. Station No. 2 

was located at a dump-car bridge 100 feet below the dam site and was 

used from November 20, 1909, to February 28, 1910, when it was 

abandoned in favor of the present site, which affords conditions more 

favorable for good results.

The gage is read twice daily and the readings indicate that the 

diurnal fluctuation is not strongly marked except at extreme high 

40183° WSP 291 12 9

stages. Some ice forms occasionally during the winter, but allowance has been made for its effect, and the accuracy of the record of 

total run-off is not impaired. The stream bed is usually dry for two 

or three months; no records have been obtained during the summer, 

for which period the discharge has been estimated.

Practically all records for this station have been collected by the 

Oregon Valley Land Co. Final computations have been made and 

the results prepared for publication by the engineers of the United 

States Geological Survey.

NOTE. Daily discharge computed by engineers of United States Geological Survey chiefly from data 

furnished by the Oregon Valley Land Co. Discharge Jan. 1-15, 1909, estimated by a comparison with 

Cottonwood Creek records. Discharge Jan. 16-May 31,1909 (station No. 1), determined from discharge 

rating curve well defined between 100 and 900 second-feet. Discharge Nov. 19 to Dec. 3,1909 (station No. 

2), determined from a curve fairly well defined between £00 and 1,200 second-feet; uncertain below 500 

second-feet. Discharge Dec. 4, 1909, to Feb. 28, 1910 (station No. 2), obtained from a curve fairly well 

defined between 70 and 1,500 second-feet; approximate below 50 second-feet. Discharge Mar. 1 to Dec. 

31, 1910 (except Dec. 1-7 and 18-31. which was estimated), (station No. 3) determined from a curve well 

denned below 1,200 second-feet. Discharge interpolated for other days on which the gage was not read.

Johns Creek, and about 2 miles above the mouth of the McCloud, 

was established December 22, 1910.

The discharge at this station plus the discharge of Pit River at 

Silverthorne Ferry, represents the discharge of Pit River at its mouth.

The gage is a vertical staff fastened to an alder tree on the right 

bank about 600 feet above the hatchery.

Discharge measurements are made from a boat about 100 feet 

below the gage.

COTTONWOOD CREEK BASIN. 

NORTH FORK OF COTTONWOOD CREEK AT ONO, CAL.

Cottonwood Creek is formed by the junction of its North and Middle 

forks, of which Middle Fork may be considered the continuation of 

the main stream. Middle Fork rises on the eastern slope of Trinity 

Mountains in the southeastern part of T. 30 N., R. 10 W., and winds 

eastward; it is about 30 miles long and drains an area comprising 

261 square miles. North Fork rises on the eastern slope of Bully 

Choop Mountain and flows very irregularly southeastward to its 

junction with Middle Fork, a short distance below Gas Point; it is 

about 20 miles long and drains an area 112 square miles in extent. 

Below the junction the main creek flows eastward and joins the Sacramento about 5 miles east of the town of Cottonwood opposite the 

mouth of Battle Creek. The principal tributary below the junction 

is the South Fork, which in turn receives the Cold Fork. The total 

area drained by Cottonwood Creek is 929 square miles.

A gaging station was established October 27, 1907, on the North 

Fork near the center of sec. 11, T. 30 N., R. 7 W., at the highway bridge one-fourth mile west of Ono, a short distance below the 

mouth of Byron Creek and about 1 mile above the mouth of Eagle 

Creek.

The gage, the datum of which lias not been changed since the 

station was established, is a vertical staff fastened to the left face 

of the middle pier of the bridge.

The channel is rather rough and subject to slight change.

At high stages the current is swift and is somewhat obstructed by 

the center bridge pier. Discharge measurements are made from the 

bridge.

Several small ditches divert water from the creek above the gaging 

station. In September, 1908, these ditches carried 14 second-feet. 

Acquired water rights greatly exceed the low-water flow of the creek.

The 1910 discharge rating curve is fairly well defined and represents an average of all the measurements that have been made since 

the station was established. The records may be considered very 

good.

MILL CREEK BASIN. 

MILL CREEK NEAR LOS MOLINOS, CAL.

Mill Creek rises in Shasta County just south of Lassen Peak, at an 

altitude of about 8,000 feet above sea level, and flows in a general 

southwesterly direction to its junction with Sacramento River, 1£ 

miles above Los Molinos.
SAN FRANCISCO BAY DRAINAGE BASINS. 139

The drainage basin lies west of Sacramento River and between the 

drainage basins of Antelope and Deep creeks.

The gaging was established September 28, 1909, by the Los Molinos Land Co., by which it is maintained. It is located one-fourth 

mile east of the company's dam, one-fourth mile west of the northeast corner of sec. 1, T. 25 N., R. 2 W., 4^ miles northeast of Los 

Molinos, and 5 miles east of Tehama, Cal.

No water is diverted from the creek above the station. At the 

dam below the station water is diverted by the company for use on 

its project in the vicinity of Los Molinos.

The gage is an inclined staff on the right bank. Only an occasional 

gage height has been obtained at this station as no regular observer 

is available.

The channel, which is composed of cemented gravel, is practically 

permanent. The current is swift at medium and high stages. Both 

banks are high and will not overflow.

Discharge measurements are made from the foot-bridge near the

gage.

STONY CREEK BASIN. 

GENERAL FEATURES.

Stony Creek drains an area comprising 828 square miles, lying on 

the eastern slope of the Coast Range, north of the Cache Creek 

drainage basin, and south of the Thomes Creek basin, which lies 

between it and the Cotton wood basin on the north. Of this area 

about 600 square miles is embraced in an irregular parallelogram 

which is 10 to 15 miles wide and touches the crest of the range for a 

distance of 50 or 60 miles. The creek rises in the south end of this
140 STJBFACE WATEK SUPPLY, 1910, PART XI.

area and flows northward along its eastern border for a distance of 

about 35 miles, then westward for about 15 miles, and finally southeastward to its junction with the Sacramento near St. John. The 

total length of the creek is about 90 miles, and its fall about 4,000 or 

5,000 feet.

The principal tributaries of Stony Creek are Little Stony Creek 

from the south end of the area, Briscoe Creek from its middle, Grindstone Creek from its north end; and North Fork, which enters the. 

main creek about 10 miles northwest of Orlaiid.

STONY CREEK NEAR FRUTO, CAL.

This station, which is located at Julian's ranch, in the SW. i 

NE. i sec. 14, T. 21 N., R. 6 W., about 7 miles northeast of Fruto 

and If miles above the proposed mill dam site, was established January 30, 1901.

The only inportant tributary near the gaging station is Grindstone Creek, which drains an area of 173 square miles and enters from 

the west a short distance above the station. Salt, Elk, and Briscoe 

creeks enter the creek some distance above the station from the south. 

North Fork of Stony Creek, which has a drainage area of about 90 

square miles, enters about 12 miles below.

The gage, the datum of which has not been changed since the 

station was established, is in two sections on the left bank and is 

read daily, with occasional extra readings during flood periods. 

The high-water portion is a vertical staff set in a rock excavation 

about 200 feet above the cable. A sloping auxiliary staff gage, 

bolted to rock, is read at low stages.

Discharge measurements are made from a car and cable.

The channel is composed of gravel which shifts more or less during 

high water, when the current is very swift and the stream is several 

hundred feet wide. The creek is not liable to overflow until it 

reaches the 15-foot stage on the gage.

The 1910 rating curve is fairly well defined for medium and low 

stages, but poorly defined for high water. The records are fair.

LITTLE STONY CREEK NEAR LODOGA, CAL.

This station, which was established by the United States Reclamation Service in March, 1907, for the purpose of determining the 

quantity of flood water available for storage in the East Park Reservoir for use on the Orland project, is located at the East Park dam 

site, 3| miles northwest of Lodoga, in the NW. | NE. | sec. 3, T. 

17 N., R. 6 W., and is about 4 miles above the mouth of the creek. 

Indian Creek enters Little Stony Creek from the east a short distance 

above the station. Two small ditches divert water for irrigation, 

one 4 miles above and the other 1 mile below the station. The total 

amount diverted is about 5 second-feet.

Since the station was first established several gages at different 

locations and with independent datums have been used. During 

the first part of 1910 the gage was an inclined staff on the left bank, 

20 feet below the cable from which discharge measurements are 

made. Since August, 1910, the gage in the East Park reservoir has 

been used to determine the discharge of the creek.

As the channel is somewhat shifting, the record for high stages is 

approximate. For medium and low stages the records are fairly 

good.

FEATHER RIVER BASIN. 

GENERAL FEATURES.

Feather River heads on the crest of the Sierra and takes a general 

southerly course to its union with the Sacramento about 30 miles 

south of Marysville and about 15 miles northwest of Sacramento. 

Its total length is about 175 miles and its drainage area comprises 

approximately 6,590 square miles, lying on the western slope of the 

Sierra Nevada, south of the Pit River basin, and north of the American River basin.

The basin is naturally subdivided into three other comparatively 

large basins: North Fork basin at the north and west, with a total 

drainage area of about 2,220 square miles; Middle Fork basin in the 

center and at the east, with a total drainage area of about 1,340 square 

miles; and Yuba River basin at the south, with a total drainage area 

of more than 1,300 square miles.

The drainage basin of the North Fork, here regarded as the main 

stream, includes the eastern part of Butte, the greater part of Plumas, 

and the southwestern corner of Lassen counties. The junction of 

North and Middle forks is in Butte County, about 6 miles northeast 

of Oroville. The length of North Fork basin does not exceed 75 

miles, and its width in Plumas County is about 65 miles. Middle 

Fork basin is long but comparatively narrow except at its east end, 

where it broadens out and includes Sierra Valley, a large meadow 

valley at an altitude of 5,000 feet. Beckwith Pass, which opens into 

this valley from the east, is the lowest pass in the Sierra Nevada, and 

has an elevation of about 5,200 feet above sea level. Sierra Valley 

and the surrounding country are very dry in the summer. The greatest elevation in the Middle Fork basin is about 8,500 feet.

Butt Creek joins North Fork from the west about 12 miles south 

of Prattville. It has a total drainage area of 74 square miles. Indian 

Creek enters North Fork from the east about 20 miles southwest of 

Prattville, and has a total drainage area of about 1,020 square miles.

SAN FRANCISCO BAY DRAINAGE BASINS. 145

Yuba River rises near the crest on the western slope of the high 

Sierra and flows southwest ward to its junction with Feather River 

at Marysville. The total length of the stream is about 90 miles. 

Its basin lies south of the Middle Fork of Feather River basin, west 

of the Truckee River basin and north of the American and Bear 

River basins, is chiefly in Yuba, Sierra, and Nevada counties, and is 

one of the principal subdivisions of the Feather River basin. It 

comprises an area of more than 1,300 square miles in extent. Its 

extreme length from the mouth of the Yuba to the crest of the Sierra 

is about 70 miles, and its greatest width is about 35 miles. The most 

important tributaries are North Fork of Yuba, South Fork of Yuba, 

and Deer Creek from the east, and North Fork of North Fork and 

Canyon Creek from the north. A dam on the South Fork of the 

Yuba is shown on Plate IV, A.

Bear River, the principal tributary of the Feather befow the Yuba, 

drains a narrow strip comprising 300 square miles, lying on the western slope of the Sierra below an altitude of 5,500 feet. The river rises 

near Emigrant Gap, in the extreme northeastern part of its basin, 

and flows south westward to its junction with Feather River about 

15 miles south of Marysville. It is the boundary line between Nevada 

and Placer counties and closely parallels the Bear-American divide, 

which is 1 to 2 miles south of it. Its principal tributaries are Steep 

Hollow Creek, Greenhorn River, and Wolf Creek, all from the north.

NORTH FORK OF FEATHER RIVER BELOW PRATTVILLE, CAL.

This station, which is located in the canyon at the proposed dam 

site of the Great Western Power Co., about 3 miles below the Meadow 

View bridge crossing on the Prattville-Greenville road, and about 5 

miles southeast of Prattville, was established by the power company 

November 22, 1905. (See PI. IV, £.)

Butt Creek enters from the west about 5 miles below the station, 

and Indian Creek from the east about 15 miles below; North Fork and 

Hamilton Branch unite about 5 miles above.

Thin sheet ice forms occasionally, but does not materially affect the 

relation between gage height and discharge.

The bed is rocky^and is not likely to change greatly. The carrent 

is swift at high water, but its velocity is moderate at other stages. At 

low water the stream is about 60 feet wide and has a maximum depth 

of 9 feet.

A staff gage is located 700 feet above the cable section. Gage 

heights are recorded by automatic register. The datum of the gage 

has remained unchanged.

Measurements were made from a boat until November 22, 1905, 

since which time they have been made from a cable and car.

SAN FRANCISCO BAY DRAINAGE BASINS. 147

NORTH FORE OF FEATHER RIVER NEAR BIO BEND, CAL.

This station was established June 13,_ 1905, and is located about 

300 feet above the head of Big Bend tunnel and about 20 miles north 

of Oroville.

No important tributaries enter for many miles above the station. 

West Branch enters from the west about 10 miles below the station 

by river, and Middle Fork comes in from the east about 20 miles below.

The datum of the staff gage remained unchanged from 1905 to 

1907. During 1908 the gage was changed several times, owing to 

construction work about the head of Big Bend tunnel.

Discharge measurements are made by means of a boat when the 

stage is below 11 feet. For higher stages float measurements are 

made at this point and check measurements are made 2 miles downstream, from the cable of the Golden State Power Co.

The stream has a rock channel which is practically permanent. At 

low water the stream is about 85 feet wide and 19 feet deep and has 

a sluggish but uniform current.

Determinations of daily discharge are published as furnished by 

the Great Western Power Co., which has maintained this station 

since its establishment.

NOTE. Estimates were computed by the Geological Survey from the daily discharge table furnished 

by the Great Western Power Co.

FEATHER RIVER AT OROVILLE, CAL.

This station, which is located near the Oroville highway bridge, in 

sec. 8, T. 19 N., R. 4 E., about 6 miles below the junction of North 

and Middle forks, and about 30 miles above the mouth of Yuba 

River, was originally established January 1, 1902. No important 

tributaries enter near the station.

No water is diverted immediately above the station, and all 

acquired water rights above are probably for power development. 

An irrigation project for lands in the vicinity of Biggs, Gridley, and 

Live Oak, is under construction. Water filings equal to the entire 

low-water flow have been made by the company interested in this 

reclamation. The point of diversion is a short distance below 

Oroville.

The United States Weather Bureau gage, located at the bridge, 

was read from 1902 to 1905. All gage heights for those years refer 

to a datum 2 feet lower than that used by the United States Weather 

Bureau in order to avoid minus readings. Discharge measurements 

were made from a boat about 500 feet above the bridge.

In December, 1905, the station was moved about 1,000 feet above 

the bridge, a staff gage was installed on the left bank, and a cable 

erected near the gage. The bridge gage was read from January 1 to 

February 28, 1906, and from September 5 to December 31; the cable 

gage from March 1 to July 24, 1906. No readings were made from 

July 25 to September 4, 1906. All gage heights for 1906 were 

reduced to the datum of the cable gage by means of a table of comparative readings on the two gages. The station was completely 

destroyed by the flood of March, 1907, which took away the gage
SAN FRANCISCO BAY DRAINAGE BASINS. 149

and the cable. From March 19 to April 7, 1907, the United States 

Weather Bureau gage on the bridge was read and the readings 

corrected to the datum of the cable gage.

On April 8, 1907, a new staff gage in several sections, referred to 

the old datum, was installed on the left bank, 1,000 feet above the 

highway bridge. 'A new cable was placed across the river October 

10, 1907, about 125 feet below the old one and 20 feet below the new 

gage.

When the station on Feather River was established at the new 

location above the Oroville Bridge the section was thought to be 

fairly permanent, but measurements made during the last four years 

show changes in the gaging section, or in the stream channel below 

the gaging section, which have made it impossible to obtain a permanent rating curve. The construction of the Western Pacific Railway 

through the canyon of the Feather resulted in washing large amounts 

of heavy debris into the river channel. Undoubtedly this debris is 

constantly being brought down tha river during periods of flood 

discharge.

There are many uncertainties in the past records on account of 

the washing out of gages, unreliable observers, and shifting channel.

Conditions for obtaining accurate measurements at high stages are 

poor. At other stages the discharge data are fairly reliable, though 

the channel is subject to change and frequent measurements are 

necessary. At low stage the stream is about 280 feet wide and 10 to 

15 feet deep, and the current is sluggish. The records for 1910 may 

be considered good.

BUTT CREEK AT BTTTTE VALLEY, CAL.

Butt Creek rises in the extreme western part of Plumas County and 

flows eastward, discharging into North Fork of Feather River about 

9 miles south of Prattville. The creek is about 25 miles long, and its 

drainage area comprises 74 square miles. It has an approximate fall 

of 3,000 feet, and is well adapted for power development.

The gaging station was established June 14, 1905, about 2 miles 

above the mouth of the creek and 100 feet below the footbridge at 

the lower end of Butte Valley. The bottom of the channel is composed of coarse gravel and shifts somewhat during extreme floods.

Measurements are made by wading at low stages and from the 

footbridge at high water. The staff gage is nailed to a post 15 feet 

below the measuring section and its datum has remained unchanged.

The records are good, as the changes in channel have been well 

covered by measurements.

Determinations of daily discharge are published as furnished by 

the Great Western Power Co., which has maintained this station since 

its establishment. .

Daily discharge, in second-feet, of Butt Creek at Butte Valley, Cal.,for 1910.

MIDDLE FORE OF FEATHER RIVER AT CROMBERG, CAL.

This station, which is located in the N. -J sec. 24, T. 23 N., R. 11 E. 

at the California White Pine Co.'s log chute, 600 feet west o'f the post 

office at Cromberg, about 4 miles below the mouth of Jamison Creek 

and half a mile above the mouth of Jackson Creek, was established 

November 3, 1910.

No water is diverted in the vicinity of the station.

The gage is a vertical staff fastened to a pier of the log chute near 

the right bank.
SAN FRANCISCO BAY DRAINAGE BASINS. 153

Discharge measurements are made by wading, as a car and cable 

have not yet been installed/

The drainage area above the station is well forested.

The station is maintained in cooperation with the United States 

Forest Service.

No estimates of daily or monthly discharge have been prepared 

for 1910.

The following discharge measurement was made by F. G. Wood, 

150 feet above log chute:

November 3, 1910: Width, 56 feet; area, 50 square feet; gage height, 2.45 feet; 

discharge, 54 second-feet.

MIDDLE FORK OF YTJBA RIVER NEAR NORTH SAN JTJAN, CAL.i

This station, which is located one-fourth mile below the highway 

bridge at Freeman's Crossing, 3 miles northeast of North San Juan, 

in the N. % NW. I sec. 23, T. 18 N., K. 8 E., in the Tahoe National 

Forest, was established October 27, 1910.

Oregon Creek enters three-fourths mile above and Moonshine Creek 

one-fourth mile below the station. The North Fork joins the Middle 

Fork about 4 miles below Freeman's Crossing.

The gage is a vertical staff wedged between two large bowlders on 

the right bank, one-fourth mile below the bridge.

As a car and cable have not yet been installed, discharge measurements are made by wa'ding or from the highway bridge.

This station is maintained in cooperation with the United States 

Forest Service.

No estimates of daily or monthly discharge have been prepared for 

1910.

YTTBA RIVER NEAR SMARTSVILLE, CAL.

This station, which is located 1 mile north of Smartsville and 20 

miles above Marysville, Cal., at a point in the foothills called The 

Narrows, in sec. 22, T. 16 N., R. 6 E., was established June 2, 1903.

Deer Creek (draining about 89.6 square miles) enters from the east 

about 1 mile above the station. South Fork of Yuba (draining 360 

square miles) and North Fork of Yuba (draining 492 square miles) 

enter from the east and north about 8 and 15 miles, respectively, 

above the station. Dry Creek (draining area 106 square miles) enters 

'from the north about 7 miles below the station.

No water is diverted immediately above the station. Extensive 

water rights have been acquired throughout this basin, and practically the entire flow of the South Fork has been preempted by filings.

The Colgate power plant of the Pacific Gas & Electric Co., located 

about 12 miles above the station, diverts water from the North Fork 

of the Yuba about 1J miles below Bullards Bar. Water is also 

diverted from the South Fork of Yuba River to the Bear River 

Basin. The records at this station do not, therefore, show the 

natural run-off from the Yuba River Basin.

At the point of measurement the channel is straight for several 

hundred feet and is filled to a great depth with gravel and sand 

tailings from hydraulic mining which are continually shifting, alternately filling and scouring. On this account frequent discharge 

measurements are made in order to determine the discharge closely. 

The banks are high and rocky and confine the river at all stages. 

The current is swift. After the rains of 1904 it was found that the 

bed of the stream had been lowered for an average depth of 2 feet. 

During recent years the bed of the stream has been lowering, and 

on August 1, 1906, the gage datum was lowered 10 feet.

The gage is a vertical staff in two sections and is read daily. The 

low-water portion is bolted to a rock wall on the left bank; the highwater portion is bolted to the wall on the right bank at the cable from 

which discharge measurements are made.
SAN FBANCISCO BAY DRAINAGE BASINS. 155

The shifting of the bed and the torrential nature of the stream 

render conditions for obtaining accurate discharge data poor. At 

high stages only float velocities can be measured. The record for 

1910 may be considered good.

NORTH FORK OF YUBA RIVER AT GOODYEAR BAR, CAL.i

This station, which is located at the highway bridge at Goodyear, 

Bar, in the E. % SW. \ sec. 5, T. 19 N., K. 10 E., was established 

October 31, 1910.

This stream is locally known as North Yuba River.
SAN FRANCISCO BAY DRAINAGE BASINS. 157

The first important tributary above the station is the North Fork 

of the North Fork at Downieville, "4 miles upstream. Rock Creek 

enters about one-eighth mile and Goodyear Creek about one-fourth 

mile below the station.

In the early days Goodyear Bar and Downieville were large placermining camps. At Downieville the entire low-water flow of the 

North Fork was diverted into a flume which extended along the side 

of the canyon for several miles. Each miner connected with this 

enterprise was allotted 30 feet of the river channel, which was carefully worked to bedrock. This section of the North Yuba was one 

of the richest placer districts in California. There is now considerable 

activity in quartz mining in this district.

The gage at this station is a vertical staff in two sections on the 

left bank: The low-water section is fastened to the old piling under 

the bridge, and the main gage is fastened to the left pier.

Discharge measurements are made from the bridge.

This station is maintained in cooperation with the United States 

Forest Service.

No estimates of daily or monthly discharge have been prepared 

for 1910.

north of the North Yuba bridge in the W. \ SW. J sec. 5, T. 19 N., 

R. 10 E., in the Tahoe National Forest, on October 30, 1910.

Although only about 300 feet above the mouth of the creek, the 

gage is believed to be above backwater from the North Yuba.

Three small ditches, having a total maximum capacity of about 

7^ second-feet, head above the station. One of these, Andrew 

Bachel's ditch, diverts water from the main creek about 1 mile above 

the mouth. Of the others, the Morgan-Casserly ditch takes water 

from Eureka Creek 3^ miles above its mouth, and the Casserly ditch 

from ^Collins Ravine 2^ miles above its mouth.

BEAR RIVER AT VAN TRENT, CAL.'

This station, which is located in the SE. i sec. 21, T. 14 N., R. 6 E., 

about 800 feet below the bridge near the Dairy Farm mine, Van 

Trent post office, and 8 miles above Wheatland, was established 

October 8, 1904, to obtain data regarding the run-off from a deforested 

drainage basin.

No tributaries enter near the station. Wolf Creek, which enters 

from the north about 20 miles above, drains about 76 square miles. 

Rock Creek, a very small stream, enters about 1 mile below. Some 

water is stored on the headwaters of Bear River, and water is also 

diverted from the South Fork of Yuba River to this basin. Hence 

the records at this station do not show the natural run-off from the 

basin. During the low- water period nearly the entire flow is used 

for irrigation above the station.

i Formerly known as "above Wheatland." Van Trent is a new post office.

The staff gage, the datum of which has not been changed since the 

station was established, is in three sections on the left bank about 

600 feet below the bridge.

In November, 1909, the car and cable were removed; since then 

measurements have been made by wading.

The rough channel and the torrential nature of the stream render 

conditions for obtaining accurate discharge data poor. The lowwater portion of the 1909 curve has been slightly revised for 1910.

The following discharge measurement was made by J. E. Stewart 

by wading:

August 4, 1910: Width, 35 feet; area, 24 square feet; gage height, 0.96 foot; discharge, 26 second-feet.

164 SURFACE WATER SUPPLY, 1910, PART XI.

AMERICAN RIVER BASIN. 

AMERICAN RIVER NEAR FAIROAKS, CAL.

American River drains an area comprising about 2,000 square 

miles lying on the western slope of the Sierra, south of Bear and 

Yuba River basins, west of Lake Tahoe and the Truckee River basin, 

and north of the Cosumnes and Mokelumne River basins.

The river is formed by the union of three principal forks, which 

rise in the high Sierra at an altitude of 9,000 to 10,000 feet. North 

and Middle forks drain areas of 349 and 640 square miles, respectively. 

Each is about 60 miles long and has a total fall of nearly 8,000 feet. 

South Fork is also 60 miles long, falls nearly 9,000 feet, and drains 

an area comprising 861 square miles. North and Middle forks unite 

near Auburn, about 20 miles above the mouth of South Fork, which 

is only a few miles above Folsom. Each of the forks has many other 

forks, branches and tributaries. The river flows southwestward to 

its junction with the Sacramento.

The gaging station, which is located in the San Juan land grant at 

the Fairoaks highway bridge, about 1,000 feet north of the railroad 

station, was established November 3, 1904.

No important tributaries enter American River above or below 

Fairoaks, except the South Fork, which joins the main stream about 

3 miles above Folsom and about 10 miles above the station.

The discharge from the South Fork of American River is affected 

by storage from Silver Lake and Echo Lake and by water diverted 

from the North Fork of Cosumnes River basin. The natural outlet 

of Echo Lake is into the Lake Tahoe drainage basin. By a court 

decree, the Sierra Water Supply Co. has secured permission to turn 

the water into the American River basin.

Water is diverted also above Placerville just below the mouth of 

Silver Fork for irrigation, mining, power, and municipal supply.

The position of the gage has been changed several times during the 

continuance of the station, but no change has been made in the datum. 

The present gage is located on the right bank at the highway bridge. 

A low-water staff gage is fastened to a pile 10 feet below the concrete 

pier on which the upper section of the gage is painted.

The old bridge was destroyed by flood in March, 1907, after which 

time measurements were made from a temporary bridge until the 

end of 1908. This temporary bridge was washed out January 13, 

1909. A new. steel bridge was completed early in 1909, and measurements are now made from it except at low water, when wading 

measurements can be made.

The current is sluggish at low water and swift at medium and high 

stages. During floods the river overflows'the left bank for several
SAN FRANCISCO BAY DRAINAGE BASINS. 165

hundred feet, but all the water passes under the bridge. On account 

of this increase in the width of the stream the mean velocity tends 

to decrease at extreme high water and hence fairly good flood measurements may be made.

The rating curve for 1910 is well defined and the estimates may be 

considered excellent.

CACHE CREEK BASIN. 

GENERAL FEATURES.

The Cache Creek, the only known outlet of Clear Lake, drains an 

area comprising 1,290 square miles, lying on the eastern slope of the 

Coast Range in Lake, Colusa, and Yolo Counties, immediately south
SAN FRANCISCO BAY DRAINAGE BASINS. 167

and west of the south end of the Stony Creek basin and north of the 

Putah Creek basin.

From the lake Cache Creek flows southeastward to Yolo basin and 

ultimately discharges into Sacramento River through sloughs. Its 

total length is about 80 miles.

The largest and most important tributary of Cache Creek is the 

North Fork, which drains 250 square miles in the eastern part of 

Lake County. The only other tributary of much importance is 

Bear Creek, which drains the western part of Colusa County. These 

creeks are very small in the summer, but rarely become dry. Al 

the tributaries are torrential.

CACHE CREEK AT LOWER LAKE, CAL.

This station was established January 1, 1901, to determine the oui - 

flow of Clear Lake. The gage and measuring section were originally 

located at the wagon bridge just below the outlet of Clear Lake, 

about 1 mile from Lower Lake, Cal., and below Siegler Creek. On. 

March 26, 1903, a cable was installed 300 feet above the bridge and 

above Siegler Creek, and a new staff gage was set 100 feet above the 

cable on the left bank in the SE. \ SE. \ sec. 34, T. 13 N., R. 7 W. 

On March 26, when this gage was set, the reading was 5.7 feet, the 

old gage reading being 4.4 feet. The gage is read daily. The gage 

datum has remained unchanged.

No tributaries enter above the station except those which come 

into Clear Lake. Siegler Creek enters about 300 feet below the 

station. North Fork joins the main creek about 14 miles below the 

lake.

The flow at the station is regulated by Clear Lake, which diminishes 

the intensity of floods and prolongs the summer flow.

Conditions at this station are peculiar. The stream bed at this 

point forms a gravel bank which controls the outlet of Clear Lake. 

The grade of the creek down to Siegler Creek is small. When Cache 

Creek is low and Siegler Creek high, the current of Cache Creek is 

reversed, and part of the water from Siegler Creek finds its way 

upstream into Clear Lake, the rest flowing downstream into Cache 

Creek. This phenomenon happens at extreme flood stages and 

causes backwater at the gage above the cable. The flow from 

Siegler Creek is very small, except at these flood periods, which are 

usually of short duration.

No discharge measurements were made during 1910. As the 

channel is firm gravel, it is practically permanent and the recorcs 

are considered good.

CACHE CREEK NEAR YOLO, CAL.

This station was established January 1, 1903, on the Rio Jesus 

Maria land grant, at the old wagon bridge on the road from Woodland to Yolo, about three-fourths mile from Yolo, and about 1,000 

feet above the railroad bridge. In the fall of 1904 a new bridge was 

constructed, and the gage record was interrupted from September 11 

to October 1, 1904.

No important tributaries enter within 12 or 15 miles of the station.

Many ditches take water from Cache Creek above the station for 

use in irrigation around Yolo and Woodland. The irrigating ditches 

usually take all the late summer flow. All available water in this 

basin has been filed upon and all lands embraced within storage 

reservoirs are held in private ownership.

The original staff gage was nailed to the upstream side of the right 

abutment of the old wagon bridge and was read twice each day. On 

October 2, 1904, a new staff gage was installed. It is in four sections, three of which are above the bridge and the fourth is bolted to 

the face of the concrete abutment on the right bank. The datum of 

the gage has been unchanged during the life of the station.

Discharge measurements have been made from the downstream 

side of the bridge.

Considered as a whole the records from January 1, 1903, to December, 1910, are good. The bed of the stream is composed of earth and 

gravel and is subject to some change. The banks are steep and well 

wooded, and their height has been increased by levees which are 

overtopped at extremely high water. The current is swift at moderate and high stages. The creek is dry at the station almost every 

summer or fall.

PITTAH CREEK BASIN.

PTTTAH CREEK AT WINTERS, CAL.

Putah Creek drains an area comprising about 810 square miles 

and lying on the eastern slope of the Coast Range south of the Cache 

Creek basin and north of Napa Valley. It includes the southern 

part of Lake County, the northern half of Napa County, and small 

parts of Yolo and Solono counties.

The creek rises in the northwestern corner of the basin, in the St. 

Helena Range, and flows southeastward into the Yolo basin near 

Davis, and thence into Sacramento River through Cache Slough. 

The total length of the creek is about 80 miles. It has numerous 

tributaries which have a heavy flood discharge in the winter but are
172 SURFACE WATER SUPPLY, 1910, PART XI.

practically dry during the summer. The chief tributaries are Soda 

Creek from the north and Pope Creek from the west.

The gaging station, which is located in the Rio de los Putos land 

grant, about 450 feet below the railroad bridge and 800 feet southeast 

of the railroad station at Winters, was established September 26, 

1905.

No important tributaries enter the creek within several miles of the 

station. No water is diverted above the station, but a small quantity 

is diverted at the station for irrigation by pumping. Recent filings 

have been made on water in this basin, and all reservoir sites are 

embraced within lands held by private ownership.

The gage consists of a series of timbers painted white and located 

under the cable. The first or low-water section is on the right bank 

and is nailed vertically to the truck of a cottonwood tree; it has a 

range of about 6 feet. The second section is on the left bank and is 

nailed vertically to the stump of a cottonwood tree. The third 

section is an inclined rod anchored on the left bank with posts. The 

fourth section is on an eucalyptus tree on top of left bank. The gage 

has been read daily.

The channel is straight and the main portion is clear. At very 

high stages the water spreads out over the left bank for about 150 

feet, reaching nearly to the foot of the left cable support. At ordinary stages, however, the water remains within the high banks.

Measurements are made during low water by wading at a point 

about 400 feet above the bridge, but at higher stages they are made 

by means of a car and cable. For float measurements a course 250 

feet long has been marked off by setting posts painted white 250 feet 

above and parallel with the cable. Floats can be dropped from the 

railroad bridge above and timed from these posts to the cable.

The records are good except at very low stages, when, owing to the 

width of channel and its tendency to shift, gage heights are not a 

reliable index of the flow.

The 1910 rating curve developed after the January flood is fairly 

well defined and the estimates may be considered good.

NORTH PACIFIC OCEAN DRAINAGE BASINS.

RUSSIAN RIVER BASIN. 

RUSSIAN RIVER AT GEYSERVILLE, CAL.

Russian River rises in the eastern part of Mendocino County on 

the west slope of the Coast Range and flows southeastward to its 

junction with Santa Rosa Creek in Sonoma County, where it turns 

westward and enters the canyon through which it flows to the Pacific 

Ocean. The total length of the main river is about 100 miles.

The principal tributaries of Russian River are East Fork, Big 

Sulphur Creek, Dry Creek, Santa Rosa Creek, and Austin Creek all 

very small, except during the rainy season.

Russian River Valley, in Sonoma County, is fertile and well 

cultivated. The climate is very equable throughout the year and 

fruit-raising is the important industry. As the climate and soil are 

especially favorable for the growing of grapes, this valley has become 

one of the most important wine-producing districts of California.

The gaging station, which is located at the highway bridge on 

the Tzabaco Spanish land grant, half a mile east of Geyserville, was 

established December 5, 1910.

As water is diverted from the South Eel to the East Fork of Russian 

River for power development, the record at this station does not 

show the natural run-off from the basin but indicates the amount of 

water available for irrigation.

The gage is painted on the lower caisson of the sixth pier from the 

right end of the bridge.
NORTH PACIFIC OCEAN DRAINAGE BASINS. 175

Discharge measurements are made from the highway bridge. 

The following discharge measurement was made by W. V. Hardy, 

from bridge:

December 4, 1910: Width, 219 feet; area, 846 square feet; gage height, 10.04 feet; 

discharge, 354 second-feet.

EEL RIVER BASIN. 

GENERAL FEATURES.

Eel River is formed by the junction of its two headwater tributaries, South Eel and Middle Eel rivers, which rise on the west slope 

of the Coast Range in the California National Forest, and together 

with the main Eel drain parts of Lake, Trinity, Mendocino, and 

Humboldt counties. The principal tributaries below Two Rivers are 

the North Fork, South Fork, and Van Duzen rivers.

The lower portion of the drainage area, below the mouth of the 

South Fork, is in the redwood (Sequoia sempervirens) belt. The 

remainder of the area is semi-open and contains very little merchantable timber except on a small tract near Grizzly Mountain. 

The lowlands are very fertile and well cultivated. The rolling and 

hlUs lands are covered with grass and are used only for grazing.

The precipitation throughout the drainage area is very heavy 

during the winter months.

SOUTH EEL RIVER AT HEARST, CAL.

This station, which is located at the highway bridge at Hearst, 

about 3 miles below the mouth of Sanhedrin Creek, in sec. 20, T. 19 

N., R. 12 W., was established December 7, 1910.

Water is diverted above the station, and is conducted through a 

tunnel to the basin of the East Fork of Russian River, where it is 

used by the Snow Mountain Power Co. for power development.

A staff gage in two sections is bolted to the bed rock on the left 

bank at the bridge, and a third section is painted on the lower caisson 

of the bridge at the left end.

EEL RIVER NEAR SCOTIA, CAL.

This station, which is located in sec. 18, T. 1 N., R. 1 E., at Wildwood Ferry, half a mile below Scotia, was established December 

15, 1910.

Van Duzen River enters the Eel about 7 miles below and Laribee 

Creek about 14 miles above the station.

The staff gage is in four sections on the left bank of the river. The 

first three sections are 70 feet above the ferry; the upper section is at 

the mouth of Dean Creek, about 150 feet farther upstream.

Discharge measurements are made from the ferry or a small boat.

No estimates of daily or monthly discharge have been prepared 

for 1910.

HAD RIVER BASIN. 

MAD RIVEE NEAR ARCATA, CAL.

Mad River rises in the southern part of Trinity County and flows 

northwestward across Humboldt County to the Pacific Ocean. The 

total length of the stream is about 90 miles.

The basin is very narrow and tributaries are unimportant. The 

upper and lower parts contain good agricultural land; the middle 

part is suitable only for grazing.

During the rainy season the river is turbulent. In the upper part 

of its course its channel is practically dry during the summer months,. 

the water standing in pools; farther down flow continues throughout 

the year, but is insufficient to irrigate all the land that is improved.

The lower course of the river is through the famous redwood 

(Sequoia, semperwrens) belt. The remainder of the basin has only a 

fair forest cover consisting of grass and scrubby timber without much 

brush.

The gaging station, which is located in sec. 14, T. 6 N., R. 1 E., at 

the Oregon & Eureka Railroad bridge, 5 miles northeast of Arcata 

and 1 mile below Warren Creek, was established December 28, 1910.

The gage is a vertical staff in two sections on the right bank at the 

railroad bridge.

Discharge measurements are made from a highway bridge just 

above the railroad bridge.

KLAMATH RIVER BASIN.

GENERAL FEATURES.

Klamath River drains a territory lying east of the Cascade Range 

in south-central Oregon and south of the Siskiyou Mountains in California. The river rises in upper Klamath Lake, flows generally 

southward, and reaches the Pacific Ocean at Requa, on the coast of 

northern California. Only that part of the basin lying in Oregon has 

been studied in detail. The drainage from this portion of the area is 

collected in large lakes whose margins are wide shallow marsh lands 

covered with tules and aquatic plants. From upper Klamath Lake, 

which stands 4,141 feet above sea level, flows Link River, a stream 1£ 

miles long, discharging into Lake Ewauna at an elevation of 4,080 feet. 

Klamath Falls, the principal city of this section, is located on Link 

River. From Lake Ewauna to the town of Keno, Klamath River 

flows through a flat marshy country a distance of 20 miles. A^out 5 

miles above Keno the river is connected with lower Klamath Lake by 

a channel known as Klamath Straits. During high stages water flows 

from Klamath River into lower Klamath Lake, and during low water 

the direction of the flow is reversed. About half a mile below Keno 

the river breaks over a rocky ledge, and here begins its precipHous 

fall of 100 to 200 feet per mile to its mouth. The drainage area above 

Keno, exclusive of lower Klamath Lake, is 3,150 square miles. The 

streams draining into upper Klamath Lake head about 6,000 feet 

above sea level. The elevation of Klamath Falls is 4,100 feet.

The principal tributaries of Klamath River are Sprague River, 

which drains the southwestern rim of the Great Basin divide in Oregon; 

Anna River, which heads in a large spring supposed to be fed by the 

waters of Crater Lake; Scott River, which drains a rich agricultural 

valley extending from Fort Jones to French Gulch; and Trinity River, 

which drains a portion of the western slope of Trinity Mountain. 

Williamson River, which drains the northern part of the Klamath 

Indian Reservation, is tributary to Sprague River. Lost River, 

although not a tributary of the Klamath, is usually considered with 

it, as a slough connects the two. Water formerly flowed in either 

direction, depending on which stream was higher, but the flow is now 

stopped by an artificial dike.

The chief tributary of Trinity River is the South Fork, which joins 

the main river a few miles below Hawkins Bar.

UPPER KLAMATH LAKE NEAR KLAMATH FALLS, OREG.

Upper Klamath Lake is to be used by the United States Keclaination Service as a source of water supply to irrigate large areas of 

land. The main canal of the Klarnath project has its intake at the 

lake.

A gage was installed on this lake near Klamath Falls, Oreg., May 28, 

1904. The elevation of the zero of the gage is 4,136.13 feet above 

sea level. The daily records since February 16, 1906, are the mean 

daily heights obtained from a Friez automatic water gage.

The winds have a marked effect on the level of the water surface 

of this lake. The water is lowered as much as 6 inches near the outlet 

when the wind blows from the south, and is raised as much over its 

nornial level when the wind is in the opposite direction. Differences 

of a foot are frequently noticeable within a few hours. If the wind 

effect were eliminated the lake heights would show much more gradual 

changes than indicated by the accompanying records,

Data for this station are furnished by the United States Reclamation Service.

180 SURFACE WATER SUPPLY, 1910, PART XI. 

LINK RIVER AT KLAMATH FALLS, OREG.

This station, which is located in sec. 32, T. 38 S., R. 9 E., at the 

county bridge over Link River at Klamath Falls, 1£ miles below the 

outlet of Upper Klamath Lake and immediately at the head of Lake 

Ewauna, was established May 15, 1904. The river has a fall of 70 

feet in the \\ miles between the lakes, a portion of which is utilized 

for water power.

The records prior to June 6, 1908, especially the individual daily 

records, are not reliable. It is probable that for longer periods a 

month or more the total flow as determined is not greatly in error. 

This condition is accounted for by the effect of wind on the flow of 

water at this station. The original gage was located at the bridge 

at the upper end of Lake Ewauna. At the outlet of Upper Klamath 

Lake the river breaks over a rather shallow ledge. A strong wind 

upstream blows the water back from this outlet and at the same time 

increases the height of water on the gage by backing the water in 

Lake Ewauna. So great is this wind effect that the river has been 

known to go entirely dry for a few hours at a time. When the wind 

is downstream the flow of Link River is greatly increased; but owing 

to the large surface of Lake Ewauna this increase in flow is not shown 

by the gage heights. In the long run these wind effects are no 

doubt compensatory, but little dependence can be placed in the 

published daily records prior to March 7, 1908. On this date an 

anemometer was installed on the bridge and a ship's taffrail log was 

trailed in the water under the bridge. It was hoped that the daily 

reading from this log would afford some indication of the velocities 

with the anemometer records. Although the records obtained by 

this device were much more reliable during 1907 than previously, 

even they were not all that could be desired. It became evident that 

owing to the sudden changes of the wind complete data could not be 

obtained without automatic recording devices on both the log and 

anemometer. The method was effective, however, in reducing the 

probable error of the estimates from about 15 per cent to within less 

than 5 per cent. On June 6, 1908, a Friez gage was installed in the 

rapids, where it could be affected only by change in flow, measurements being made at the bridge as formerly.

For the remainder of 1908 and for 1909 the records obtained are 

reliable. During 1910 water was diverted around the Friez gage in 

the rapids, for use by the power plant operated by Moore Bros. 

This water was returned to the river between the Friez gage and the 

gage at the bridge. No daily record was kept of the amount of 

water thus diverted around the Friez gage, although several measurements of the amount of water in Moore Bros.' flume were made. 

Only one measurement was referred to the Friez gage during the
NOBTH PACIFIC OCEAN DEAINAGE BASINS. 181

year. The Friez gage readings were also somewhat affected by backwater from log jams. The daily discharge for 1910 must therefore 

be determined from the gage at the bridge, subject to all the uncertainties noted above.

This station was maintained during 1910 by the United States 

Reclamation Service, but the daily and monthly discharge tables 

were computed by the United States Geological Survey.

KLAMATH RIVER AT KENO, OREG.

This station, which is located at the county bridge at Keno, in 

sec. 31, T. 39 S., R. 8 E., at the lower end of the lakes and marshes 

that form the headwaters of Klamath River, was established May 

31, 1904. The United States Reclamation Service is reclaiming 

lands for irrigation in two ways by diverting waters from Klamath 

Lake and by draining the large swamp areas Bordering this stream 

and the lakes which are tributary to it. Immediately below the 

station the river breaks over.a rocky ledge with a fall of about 200 

feet to the mile.

During the winter the river usually freezes over, but as the water 

is comparatively deep and the ice is not very thick the accuracy of 

records has not been greatly affected by the ice. At low stages a 

growth of aquatic plants clogs the section and to some extent lessens 

the accuracy of the results. An additional source of error has 

resulted from the effect of wind on the wide expanse of water above 

the station. A strong upstream wind will blow the water back from 

the outlet and diminish the flow, but as the gage is located at the 

bridge, 1,000 feet above the gaging site, gage heights are not always 

affected to a corresponding degree. The datum of the gage has not 

been changed since it was installed.

Discharge measurements are made from a cable 1,000 feet below 

the gage.

This station was not visited in 1910, but conditions seem to be 

fairly permanent, and the 1909 discharge rating curve is believed to 

give reasonably close results. The station was maintained during 

1910 by the United States Reclamation Service, but the daily and 

monthly discharge tables were computed by the United States 

Geological Survey.

KLAMATH RIVER NEAR REQUA, CAL.

This station, which is located at JSTye's ranch in sec. 29, T. 13 N., 

R. 2 E., 9 miles above Requa, was established December 25, 1910. 

It is 30 miles below the mouth of Trinity River and 10 miles above the 

mouth of Klamath River.

The staff gage is in four sections on the right bank near the ferry.

Discharge measurements are made from the ferry or a small boat.

186 SURFACE WATER SUPPLY, 1910, PART XI.

WILLIAMSON RIVER NEAR KLAMATH AGENCY, OREG.

This station, which is located 13 miles northeast of the Klamath 

Agency, in the NW. | sec. 1, T. 33 S., R. 7 E., at a point locally 

known as Rocky Ford, at the lower extremity of Klamath Marsh, 

was established March 26, 1908, in cooperation with the United 

States Office of Indian Affairs, and discontinued June 26, 1910, as the 

observer moved away and no other was obtainable.

The nearest tributary is Spring Creek, 11 miles below the station. 

Owing to the inaccessibility of the station, it has not been practicable 

to obtain continuous records of discharge. During the winter months 

it is almost impossible to reach the station on account of snow.

Discharge measurements are made from a cable and car.

The staff gage was originally located about 1,000 ieet above the 

cable. On October 17, 1908, a Bristol self-registering gage was 

installed, and as this required only weekly visits by the observer, 

continuous records were obtained during the remainder of the year. 

The gage was moved May 30, 1909, to a point 100 feet downstream 

at the location of the cable. It was set to read the same as at the 

former location, but on account of the slope of the river there is no 

constant relation. The datum of the gage as reset is at an elevation 

of 4,622.19 feet above sea level. On November 10, 1909, an auxiliary 

staff gage was installed below the mouth of Spring Creek to be used 

when the regular station is inaccessible. Simultaneous readings 

were made on both gages from November, 1909, to June, 1910. The 

upper gage was washed out during the high water of March, 1910, 

and was replaced April 15, with a Bristol self-recording gage.

In the meantime weekly readings were continued on the lower 

gage. The relation between the two gages has been determined 

and the gage heights for the missing period have been estimated.

Owing to the large storage capacity in Klamath Marsh the river 

is not subject to great fluctuations. It is probable that weekly 

observations will give sufficient data for an estimate of the flow.

The accuracy of the results is somewhat affected by the growth of 

aquatic plants in the river channel during the season, and' a comparatively large number of measurements will be necessary in order 

to secure reliable results. The data herewith were obtained by 

usual methods, using a mean curve. The following measurement 

was made by Leland Moser 1 August 11, 1910: Width, 80 feet; area of 

section, 150 square feet; gage height, 0.54 feet; discharge, 55.2 secondfeet.

i The results of this measurement are very uncertain, as the velocity was very low and the whole river 

bed was covered with grass and tules.

NOTE. Gage heights Apr. 15 to June 26, obtained by means of a Bristol automatic pressure gage. The 

river was frozen most of the time during January and February. The ice was breaking up Feb. 27, and the 

channel probably cleared soon after. Gage heights for Mar. 13 to April 10 have been estimated from those 

observed below Spring Creek.

NOTE. Daily discharge determined by means of the gage heights at Rocky Ford and a fairly well-defined 

discharge rating curve the same as that used for 1909. The measurement made during 1910 is believed not 

to be reliable. Discharge for January and February reduced by varying amounts to allow for effect of ice 

as indicated by the observer's notes; discharge interpolated between dates when gage was read.

LOST EIVEE AT OLENE, OEEG.

This station was originally established May 24, 1904, at the county 

bridge at Olene in sec. 14, T. 39 S., R. 10 E., and was maintained until 

July 30 of that year, when the bridge at which measurements were 

made was destroyed and the station was discontinued. It was 

reestablished May 20, 1907, and the records have been continuous 

since that date. This station replaces the one at Merrill, simultaneous
NOBTH PACIFIC OCEAN DBAINAGE BASINS. 189

records being kept a sufficient length of time to make a comparison 

between the two. The difference of flow is largely accounted for by 

the inaccuracy of the data obtained at Merrill station.

A slough connecting Lost River with Klamath River joins Lost 

River 5 miles below the Olene station and Klamath River 2 miles 

below Lake Ewauna. Through this slough it ie proposed to divert 

part of the waters from Lost River into Klamath River, and thus 

reclaim lands bordering Tule Lake. At present, however, the slough 

has been artificially closed and the flow has been shut off for several 

years. Before it was diked no water flowed except during high water, 

the direction depending upon whether Klamath or Lost River was the 

higher.

There is a small amount of inflow below Olene. One spring was 

measured April 14, 1908, giving a discharge of 2.9 second-feet, and 

during the irrigating season there is probably some waste water from 

irrigation. Nuss Lake is situated half a mile from the left bank of 

Lost River and 1 mile below Olene. It has no surface outlet except at 

flood time, but it is possible that a little water passes underground 

from this lake to the river during the summer months.

A hook gage has been used since April 23, 1909, in order to insure 

more accurate readings, the datum having remained the same.

Measurements are made from the highway bridge to which the gage 

is attached or at low water by wading. In defining the discharge 

curve the wading measurements have been given greater weight than 

low-water measurements at the bridge.

This station was maintained during 1910 by the United States 

Reclamation Service, but the tables of daily and monthly discharge 

were computed by the United States Geological Survey.

«Including area above Clear Lake reservoir dam, 550 square miles, which strictly should be deducted, 

as no water was allowed to escape during 1910.

TULE LAKE NEAR MERRILL, OREG.

This station, which is located at J. F. Adam's ranch near the mouth 

of Lost River, in sec. 9, T. 41 S., JR. 11 E., about 3 miles east of 

Merrill, was established May 17, 1904.

The elevation of the zero of the gage has been taken as 4,048.21 

feet above sea level. When the station was established the gage was 

referred to a bench mark on a juniper post near by. The bench 

mark at that time was 13.7 feet above the zero of the gage. On 

October 21, 1904, this elevation was verified. On May 11, 1907, the 

elevation of the same bench mark was found to be 12.87 feet above 

zero of the gage, and was independently verified on June 11, 1907, 

and again on November 27, 1908. It appears, therefore, that sometime between October, 1904, and May, 1907, gage was raised 0.87 

foot. This change was probably due to action of ice in the lake, 

although nothing of this kind has been observed since that time. 

Just when it occurred it has been impossible to ascertain, and a 

graph of the heights has failed to reveal any critical points that would 

account for a sudden change. It is therefore likely that the gage was 

raised 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 refined studies.

The data for this station are furnished by the United States 

Reclamation Service.

MILLER CREEK NEAR LORELLA, OREG.

This station, which was established August 10, 1904, was originally located in sec. 13, T. 39 S., R. 13 E., at the lower end of 

Horsefly Valley. On April 1, 1909, it was moved to an old highway 

bridge in sec. 7, T. 40 S., R. 14 E., 3 miles south of Lorella post office 

and 1 mile east of the Swingle ranch in Langell Valley. All measurements in 1909 were referred to this gage. Both points are below all 

tributaries and the results should be comparable, although the drainage area at the lower station is 50 square miles greater than at the 

upper, the areas being 270 and 220 square miles, respectively.

A small amount of water is diverted for irrigation by a dam about 

one-fourth mile above the present station.

A vertical staff gage is attached to the bridge, and its datum has 

remained unchanged since the station was re-established. A Bristol 

self-recording pressure gage was installed May 2, 1909; the records 

obtained from it have been used during high water, but during low 

stages it was too much affected by temperature changes and the 

weekly readings of the staff gage have been used. The Bristol gage 

was replaced by a Friez recording gage on January 30, 1910, and since 

that time the gage heights have been fully reliable.
NORTH PACIFIC OCEAN DRAINAGE BASINS. 193

Discharge measurements are made from the highway bridge or by 

wading at low water.

During the winter months the river freezes over completely, and 

the data obtained at such periods are not reliable, but a large error 

during such periods is admissible without affecting the total annual 

flow. At flood stages, even during the winter, the relation between 

gage height and discharge is probably not affected by ice.

The conditions at the station during the open season are favorable 

for good results. A riffle that controls the flow just below the station 

seems to have shifted slightly during the spring flood of 1910.

High water measurements made 1911 indicate that the computed 

flood discharge of November, 1909, is considerably too small, but the 

yearly total is not materially affected thereby.

The 1911 measurements are published herewith, as they have been 

used in constructing the discharge rating curve.

This station was maintained during 1910 by the United States 

Reclamation Service, but the tables of daily and monthly discharge 

were computed by the United States Geological Survey.

NOTE. Gage heights obtained from a Bristol automatic pressure gage until January 30, and from a Friez 

gage thereafter. The low readings for January 9 to 20 were probably caused by the low temperature and 

not by low stage of water. No ice noted; the creek freezes over at the bridge, but probably not at the riffle 

control, so that gage readings may not be materially affected.

The low water readings are not very accurate as the pen of the Friez gage was evidently set only to the 

nearest tenth of a foot.

EAST FORK OF SCOTT EIVEE NEAR CALLAHAN, CAL.

Scott Kiver rises in the Scott Mountains in the southern part of 

Siskiyou County, and flows northwestward to its junction with Klamath Kiver near Hamburg Bar. The length of the main river from 

the junction of the South and East forks near Callahan is about 50 

miles. The basin is narrow and the tributaries are small. Scott 

Valley, extending from Fort Jones to French Gulch, is a rich agricultural vaUey. Below this vaUey the river enters a canyon in which 

it continues to its mouth.

The gaging station, which is located 500 feet west of W. Schneider's 

ranch house, 6 miles east of CaUahan, in sec. 18., T. 40 N., R. 7 W., in 

the Shasta National Forest, was established November 1, 1910.

The gage is a vertical staff fastened to a willow tree on the left bank.

Discharge measurements are made from the foot log 30 feet below 

the gage.

This station is maintained in cooperation with the United States 

Forest Service.

No estimates of daily or monthly discharge have been prepared for 

1910.

TRINITY RIVER NEAR TRINITY CENTER. CAL. » '

This station, which is located 500 feet below the highway bridge 

2 miles southeast of Trinity Center, in the NE. | sec. 16, T. 36 N., 

R. 7 W., in the Shasta National Forest, was established December 15, 

1910.

Brush Creek enters about one-half mile and Coffee Creek about 6J 

miles above the station. Swift Creek enters 1 mile below. The 

East Fork of Trinity River joins the main stream about three-fourths

The gage is a vertical staff on the right bank.

Discharge measurements are made from the bridge 500 feet above 

the gage.

A small amount of water, diverted from the North Fork of Swift 

Creek for placer mining, enters a short distance above the station. 

Otherwise the record at this point represents the natural run-off from 

this drainage area.

This station is maintained in cooperation with the United States 

Forest Service.

The following discharge measurement was made by F. G. Wood, 

from bridge. December 15, 1910:

Width, 134 feet; area, 151 square feet; gage height, 3.47 feet; discharge, 509 second 

feet.

COFFEE CREEK AT COFFEE, CAL.

This station, which is located at a private bridge at Coffee, 6 miles 

above the mouth of the Creek, in the NW. i sec. 4, T. 37 N., R. 8 W., 

in the Shasta National Forest, was established December 16, 1910. 

Boulder Creek enters 400 feet above and Little Boulder Creek 1| 

miles below the station.

The gage is a vertical staff on the right support of the bridge.

Discharge measurements are made from the bridge.

This stream is utilized by the Trinity Gold Mining & Reduction Co. 

to operate the mine near Carrville. At certain times of the year the 

operation of two "self-shooter" dams above the station may affect 

the accuracy of the records. Each of these dams is controlled by a 

gate which opens when the desired head is reached. As soon as the 

reservoir is emptied, (the larger one in about half an hour) the gate 

closes automatically. These dams are used in connection with the 

placer mining.

This station is maintained in cooperation with the U. S. Forest 

Service.

The following discharge measurement was made by F. G. Wood. 

December 16, 1910:

Width, 41 feet; area, 148 square feet; gage height, 4.17 feet; discharge, 176 second feet.
