WATER RESOURCES OF CALIFORNIA.

PART I. STREAM MEASUREMENTS IN SACRAMENTO

RIVER BASIN.

By H. D. MCGLASHAN and F. F. HENSHAW.

INTRODUCTION.

The great part which the water resources have had in the development of California is evident throughout its history.

Repairs to a mill race near Georgetown, Eldorado County, in 1848, 

led to the discovery of gold, and the development of the gold-mining 

industry was due largely to the location of the deposits near the 

water necessary for hydraulicking.

The water available for irrigation and domestic supply has been' 

the chief factor in the development of sputhern California, which 

now has a population of more than 1,000,000 people.

The growth of irrigation systems in the great interior valley is 

bringing about its subdivision into small ranches devoted to the 

intensive farming which affords almost limitless opportunities to the 

agriculturist.

An increased water supply for the city of San Francisco is one of 

its greatest necessities, and more water for Los Angeles is to be brought 

from Owens Valley a distance of more than 200 miles at. a cost of 

$23,000,000.

The many mountain streams of California afford abundant hydroelectric power, the utilization of which in manufacturing enterprises 

and in transportation has been made possible by the progress of 

electric-power transmission during the last decade; to-day California 

probably leads the country in the number and length of her powertransmission lines.

Information concerning the quantity of water carried by the 

streams has been and will continue to be an important factor in the 

development of these resources, for the fundamental importance of 

stream-flow data is now so thoroughly recognized that it is almost 

impossible to finance any project depending on stream flow without 

presenting authentic records of flow covering a period of years.

The measurement of the flow of streams in California was begun 

by the California State engineer in 1878, in accordance with the law

7

requiring him "to investigate the problems of the irrigation of the 

plains, the condition and capacity of the great drainage lines of the 

State, and the improvement of the navigation of rivers." The work 

was restricted to a few localities in the Sacuamento and San Joaquin 

River basins, the principal station being on the Sacramento at 

Collinsville.

The State engineer's office was discontinued in 1884, and practically 

no further stream studies were made until 1894, when engineers of 

the United States Geological Survey were sent into California and 

made a few measurements of streams in the semiarid parts of the 

State. The following year the Survey established a station on 

Sacramento River at Red Bluff and since that time has gradually 

extended the work until it now has available records of flow at 289 

points on California streams. Many records have also been collected 

by private parties. The first stations were located only on streams 

whose waters were to be used for irrigation, but records are now 

available on streams adapted to all uses, including navigation, 

domestic water supply, and power.

To make this information available six reports are being prepared. 

The reports are to be published as water-supply papers and will bear 

tthe following titles:

295. Gazetteer of surface waters of California, Part I, Sacramento River basin.

296. Gazetteer of surface waters t>f California, Part II, San Joaquin River basin.

297. Gazetteer of surface waters of California, Part III, Great Basin and Pacific coast 

streams.

298. Water resources of California,, Part I, Stream measurements in Sacramento 

River basin.

299. Water resources of California, Part II, Stream measurements in San Joaquin 

River basin.

300. Water resources of California, Part III, Stream measurements in Great Basin 

and Pacific coast river basins.

The gazetteers embrace descriptions of all the streams named on the 

best available maps; the stream-measurement reports describe the 

streams that have been measured and the stations at which the work 

has been carried on and present the results of the studies of stream 

flow.

The investigations of the quantity of Water in the streams have * 

been supplemented by studies of the climatic and other factors 

affecting stream flow, and a mass of valuable information has thus 

been collected affording data for all phases of hydraulic work.

COOPERATION AND ACKNOWLEDGMENTS.

Cooperation in stream measurements between the United States 

Geological Survey and State of California was first provided for by 

the State legislature in an act approved March 16, 1903. This act 

covered the period from July 3, 1903, to June 30, 1905, and was in 

substance as follows:
STREAM MEASUREMENTS IN SACRAMENTO BASIN. 9

The State board of examiners are hereby empowered to enter into contracts with the 

Director of the United States Geological Survey for the purpose of making topographic 

maps to the extent of twenty thousand dollars; also for the purpose of gaging streams; 

surveying reservoir sites and canal locations, for the conservation and utilization of the 

flood and storm waters of the State, to the extent of fifteen thousand dollars. * * *

Similar acts, approved March 20, 1905, and March 11, 1907, provided for the continuation of the work until June 30, 1909, with an 

increased biennial appropriation of $30,000 for topography and 

$20,000 for hydrography. The act of March 11, 1907, named the 

department of engineering of the State of California as the cooperating party.

An act placing cooperation between the State of California and the 

United States Geological Survey on a permanent basis was approved 

on April 22, 1909, and provided as follows:

The department of engineering is hereby empowered to carry on topographic surveys 

and investigations into matters pertaining to the water resources of the State along the 

lines of hydrography, hydro-economics and the use and distribution of water for agricultural purposes, and to that end, where possible and to the best interest of the State, 

shall enter into contracts for cooperation with the different departments of the Federal s 

Government in such amounts as may be an equitable and necessary division of the 

work. The State engineer, with the consent of the governor, may maintain and continue such investigations where there is available money not covered by cooperation 

contract. For the permanent maintenance of said surveys and investigations there is* 

hereby tontinuously appropriated out of the general fund of the State treasury for each 

and every fiscal year, commencing with the date upon which this act becomes effective, 

the sum of thirty thousand dollars.

Of this sum $9,000 is allotted annually to investigations of water 

resources.

In 1911 the California Legislature provided for a State board of 

control (water powers), to pass on matters pertaining to the appropriation of water for power development, and for a conservation 

commission to investigate and collect information concerning the 

subjects of forestry, water, and other natural resources and their use, 

for the purpose of revising the laws of the State relating thereto. 

The legislature of 1912 transferred the duties of the State board of 

control (water powers) to the State water commission.

In present work the State of California is represented by the department of engineering, State of California W. F. McClure, State 

engineer; by the conservation commission George C. Pardee (chairman), Francis Cuttle, and J. P. Baumgarten; and by the State water 

commission, Hiram W. Johnson, governor; Charles D. Marx, chairman; S. C. Graham; Harold T. Power, and W. F. McClure. Louis R. 

Glavis is secretary of both commissions.

The earliest stream gaging work in the State was carried on under 

the direction of Wm. Ham. Hall, State engineer, by C. E. Grunsky, 

who continued in charge until the State engineer's department was 

abolished. Work by the United States Geological Survey was begun
10 WATEB BESOUECES OP CALIFOBNTA PAET I.

in 1894, under the direction of F. H. Newell/ chief hydrographer, by 

Arthur P. Davis and Joseph B. Lippincott. On the establishment of 

the United States Reclamation Service, in 1902, Mr. Lippincott became supervising engineer for California, and the field work was continued under his direction by William B. Clapp and Samuel G. Bennett, until the separation of the Reclamation Service from the Geological Survey in 1906, when Mr. Clapp became district engineer. On 

Mr. Clapp's death in December, 1911, H. D.McGlashan was appointed 

district engineer. Numerous assistants have participated in the field 

work, and as their names appear in connection with the measurements 

which have been made they will not be repeated here. Special 

acknowledgment should, however, be made to W. F. Martin, who was 

Mr. Clapp's principal assistant from June, 1906, to November, 1909, 

when he was transferred to work in Hawaii, and to R. C. Rice and 

H. J. Dean, who have assisted in the work of compilation and computation. Many records have been collected in cooperation with 

private individuals, to whom credit is given in connection with the

published data.

TOPOGRAPHY.

California is traversed on the east and west by two approximately 

parallel ranges of mountains the Sierra Nevada and the Coast 

Range which converge at Mount Shasta on the north and ^at Tehachapi on the south and inclose the largest body of fanning land in 

the State, the area often spoken of as the Great Valley of California. 

This valley is a gently sloping and practically unbroken plain, about 

400 miles long and ranging in width from a few miles to 80 miles, 

with an average width of 40 miles. The total area of the valley proper 

is 15,700 square miles, or 10,048,000 acres; including mountains and 

minor valleys it comprises more than 58,000 square miles.

On the east side the valley has since the beginning of Cretaceous time been bordered 

by the Sierra Nevada; on the west side diastrophic processes have gradually built up 

the barrier of the Coast Ranges, changing the depression from a gulf of the sea to a lake 

and from a lake to a drained valley. From the beginning of the Cretaceous period the 

Great Valley has been the depository of enormous masses removed by erosion from the 

rising land on the east, and to a less degree also of the debris from the Coast Ranges. 1

The northern portion of the Great Valley is drained by Sacramento 

River; the southern portion is drained by the San Joaquin. The 

two rivers unite at the head of Suisun Bay, from which they pass 

through San Pablo and San Francisco bays and the Golden Gate to 

the Pacific Ocean.

The area drained by the Sacramento is divisible, according to elevation, into three parts (1) the central region, known as the Sacramento Valley, whose general elevation is less than 500 feet above sea

level; (2) the foothill region, made up of hills and ridges ranging in 

altitude from 500 to 2,300 feet and traversed by ravines and canyons 

of moderate depth; (3) the mountain region, in which altitudes 

exceed 2,300 feet above sea level. A general idea of the configuration 

of the land may be obtained from the relief map of northern California (PL I).

Sacramento Valley, which is by far the most important area in the 

drainage basin, lies along the lower course of Sacramento River for a 

distance of about 150 miles northward from its mouth. The elevation 

of the valley ranges from about 300 feet above sea level at Red Bluff 

to only a few feet at the mouth of the river. Except for Marysville 

Buttes, in its center, its slope is gentle and uniform, ranging from 

approximately 4 feet to the mile in the north to less than ; 6 inches 

to the mile in the south.

The monotonous surface of the alluvial plains of the Sacramento Valley is scarcely 

broken by any recognizable relief; the lowest depressions are covered with swamp 

grass and tule, among which are tortuous sloughs and sheets of standing water, widening 

in flood times to vast lakes. The only sharply salient features are the river banks of 

sand and clay, from a few feet to 20 feet high. The valley floor is the gently sloping 

surface of a Pleistocene lake bottom, only recently drained by constructive processes. 

The rivers are at their base-level and in their sluggish course deposit the loads of sand 

and clay brought down from the mountains, corrade their banks, and endeavor to 

establish new and changing channels. 1

The total area of Sacramento Valley is about 4,250 square miles, 

including 2,510 square miles of high lands not subject to oyerflow but 

requiring irrigation for successful farming; 450 square miles of lower 

lands, overflowed occasionally; 1,250 square miles of low lands, 

overflowed periodically and submerged for a considerable period of the 

year; and 38 square miles of perennial stream surface.2 It is thus evident that about 40 per cent of the valley suffers from floods and about 

60 per cent from drought. The valley as a whole suffers from an excess 

of water at one season and a deficiency at another. The problem 

of remedying these defects embraces three distinct phases the 

preservation and improvement of navigation, the reclamation of 

swamp and overflowed lands, and the development of irrigation for 

all the higher lands.

The floods occur in winter or early spring. The worst floods in 

recent years were those of 1904, 1907, and 1909. Each succeeding 

flood seems to cause more damage in proportion to the volume of 

water, partly because there is more property to be damaged and 

partly because of the effect of d6bris in the river channels. An account of the flood of March, 1907, prepared by W. B. Clapp, E. C. 

Murphy, and W. F. Martin, engineers of the United States Geological 

Survey, was published early in 1908. 3

From the rim of the valley there is a gentle rise across the zone of 

low-lying foothills, and steeper rise up the mountain side to the divide 

on the summit of the encircling ranges. The eastern watershed 

ranges in elevation from 10,000 feet in the south to 6,000 feet in the 

north; the western watershed ranges from 4,000 feet in the south to 

9,000 in the north; and the northern from 4,000 to 8,000 feet, exclusive of Mount Shasta, which rises 14,380 feet above sea level.

The mountain ranges surrounding the basin belong to the Cordilleran system. The Sierra Nevada has an average width of approximately 70 miles from the rim of the valley to the crest of the 

range, which lies only a few miles west of the eastern boundary of 

the State. The range terminates in the Warner Mountains, in the 

northeastern part of the State, a region presenting evidence of recent 

volcanic action. Vast beds of lava cover the western slope of the 

range, and many cones, craters, ash deposits, and lakes exist in the 

vicinity of Mount Shasta and Lassen Peak, which are themselves the 

cones of extinct volcanoes. The Coast Range has an average width 

of approximately 35 miles from the rim of the valley to the crest, 

which lies inland from the shore at a distance ranging from 30 miles 

at the south to nearly 100 miles at the north, where the range takes 

the name Trinitv Mountains.

DRAINAGE.

THE MAIN STREAM.

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 by 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. At a point 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. Most of the streams 

from the Coast Range do not reach the Sacramento directly but become 

lost "in the intricate plexus of sloughs which meander through the 

tule lands bordering the main river. On the east, also, only the 

larger tributaries reach the Sacramento by a definite channel, and 

often that becomes an exceedingly tortuous one." 1

Above the mouth of Pit River the Sacramentb is a comparatively 

small stream, flowing swiftly in a well-defined chjannel; below the Pit 

it is larger, and at Red Bluff, where it enters Sacramento Valley, 

it becomes a sluggish stream, of small slope and spiall capacity. It is 

navigable to Red Bluff, 250 miles above its moullh.

Below the mouth of Stony Creek, throughout a large part of its 

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 thr< >ughout 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 w[ater may thus pass 

from the river into the flood basins and be stdred for a time, thus 

reducing the maximum rate of flow of the Sacraijnento 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 r.orth 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 divic ed into four basins 

called, from north to south, Butte, Sutter, American, and Sacramento by Marysville Buttes and Feather a:id American rivers. 

The total area of these large 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.
14 WATEE EESOUBCES OF CALIFORNIA PART I.

The following data in regard to the area and capacity of these basins 

are taken from the Keport of the Commissioner of Public Works to 

the Governor of California for 1904:

Colusa Basin is 50 miles long, from 2 to 7 miles wide, and "has a 

capacity of 690,000 acre-feet at flood stage. It discharges into the 

Sacramento above Knights Landing through Sycamore Slough.

Yolo Basin is 40 miles long, 7 miles in average width, and its 

capacity at flood stage is 1,115,000 acre-feet. It discharges through 

Cache Slough into Steamboat Slough and thence into the Sacramento 

near the foot of Grand Island, about 25 miles above the head of 

Suisun Bay.

Butte Basin is north of Marysville Buttes and its area varies from 

30 to 150 square miles, depending on the river stage; its capacity at 

flood stage is 450,000 acre-feet. It discharges through Butte Slough 

into Sutter Basin.

Sutter Basin is south of Marysville Buttes and north of Feather 

River. Its area is 138 square miles, and its flood-stage capacity is 

895,000 acre-feet. It discharges into Sacramerto River through 

sloughs above'the mouth of Feather River.

American Basin is south of Feather River and north of the American. 

Its area is 110 square miles, and its capacity at flood stage is 571,000 

acre-feet. It discharges into the Sacramento north of the city of 

Sacramento, but owing to its great depth it is never free from water.

Sacramento Basin is a narrow strip south of American River, extending from the city of Sacramento to Walnut Grove. It is filled by 

overflow from Mokelumne River or the Sacramento, but not so frequently as the other basins are filled.

Many islands have been formed in the delta region between the 

lower courses of the Sacramento and the San Joaquin. Several 

sloughs carry the water of one river to the other among the islands, 

especially at higher river stages. The islands range in size from 1,600 

to 43,000 acres and are very fertile, but they are so low that those 

unprotected by levees are overflowed every year.

THE BRANCHES.

PIT RIVER.

Pit River is formed near Alturas, in Modoc County, by the union 

of its North and South forks. The South Fork rises on the western 

slope of Warner Mountains, about halfway between Warren and 

Eagle peaks, at an altitude 8,000 feet above sea level, flows southwestward 10 miles, westward about 10 miles, then turns and flows 

northward 16 miles through a swampy meadow to its junction with 

the North Fork. The North Fork flows southward from a point about 

half a mile south of Goose Lake but normally receives no overflow
STEEAM MEASUREMENTS IN SACRAMENTO BASIN-. 15

from that water body. As overflow has, however, been recorded,1 

and as it is possible that water from the lake may reach the river by 

underground channels in the porous lavas which characterize this 

section, the area tributary to the lake is considered a part of the Pit 

River basin. The principal direct tributaries of the North Fork of 

the Pit Swedrengen, Joseph, and Parker creeks rise on the western 

slopes of the Warner Mountains, 6,000 feet above sea level, and flow 

westward, descending 1,200 feet in courses that measure less than a 

dozen miles.

From Alturas the Pit takes a general southwesterly course to its 

junction with the Sacramento about 12 miles north of Redding. 

The total fall between the head of the South Fork and the mouth of the 

main stream is about 7,300 feet, of which 3,550 occurs on the South 

Fork in the first 18 miles of its course.

Physically tfre Pit basin is not tributary to the larger Sacramento 

basin, but is really its upper extension under a different name. It 

comprises about 7,000 square miles, equal to about 23 per cent of the 

total area of the Sacramento River basin. The greater part of the 

basin of the Pit exceeds 4,000 feet in elevation and consists chiefly of 

barren lava beds in the north and numerous small, flat, marshy 

meadow valleys in the south. The area contains also many volcanic 

buttes and peaks, of which Mount Shasta (14,380 feet above sea level) 

and Lassen Peak (10,437 feet above sea level) are the most important, 

but these peaks are on the Pit basin divide and are shared in common 

with the upper Sacramento and Feather River basins, respectively.

About 50 per cent of the Pit basin is devoid of forests, the timberless 

area lying chiefly in the northern and eastern parts. There are two 

well-forested areas in the basin one south of Pit River and north of 

Lassen Peak, and the other north of Pit River and south of Mount 

Shasta, extending westward from Fall River to the upper Sacramento 

River and including the McCloud basin. All the public land in the 

forested areas is included in national forests.

The principal tributaries of Pit River are McCloud River, Squaw 

Creek, and Fall River, from the northr, and Burney, Hat, Beaver, 

Ash, and West Valley creeks from the south. McCloud and Fall 

rivers are the largest, each having a minimum flow of 1,200 to 1,500 

second-feet. Hat and Burney creeks have a minimum flow of less 

than a hundred second-feet. Goose Lake, though topographically 

tributary to the Pit basin, has discharged water to it only once 

since 1869; it is said to have overflowed in 1881 for more than two 

hours during a severe storm from the north.

McCloud River drains an area comprising 649 square miles, lying 

just east of the upper Sacramento basin. The river rises in large

springs southeast of Mount Shasta, but its main water supply comes 

directly from the southern and eastern slopes of Mount Shasta 

through Squaw, Mud, Cold, and Ash creeks, its tributaries. The 

river flows southward, is about 60 miles long, and falls more than 

4,000 feet. It discharges into Pit River about 4 miles east of the 

confluence of the latter with the Sacramento.

The precipitation in Pit River basin is very unevenly distributed. 

In the upper eastern part, of the basin it is only about 10 inches 

annually and occurs largely as snow, which at moderate ~ altitudes 

soon melts. In the western and northwestern parts, however, the 

mean annual precipitation ranges up to 75 inches, according to 

altitude, and occurs principally as rain except on the upper slopes 

of Mount Shasta, Lassen Peak, and other high peaks. In the McCloud basin it is seldom less than 40 inches and occasionally reaches 

100 inches annually. Practically all the precipitation is confined 

to the rainy season from November to April of each year.

The valleys of the Pit basin are used chiefly for meadow lands 

and the growing of stock feed. Some of them are flooded artificially 

for the raising of wild hay. The uplands are used only for domestic, 

pasturage and for general stock raising, which is carried on extensively.

Numerous reservoir sites on the upper reaches of the Pit and its 

tributaries have been surveyed by the United States Reclamation 

Service. A reservoir at the Big Valley site, near Bieber, would 

store more water than the river furnishes at this point. Warm 

Spring reservoir, at Canby, would also have a large storage capacity.

The basin also affords exceptional opportunities for power development, especially below Fall River Mills, which is about half way 

between the source and mouth of the Pit. It is estimated that 

Fall River could develop more than 30,000 and McCloud River 

more than 200,000 horsepower continuously. Pit River and its tributaries could develop a total of about 1,000,000 horsepower continuously. About 50 per cent of this amount is commercially feasible 

of development, and only about 2 per cent has been developed.

Many perennial springs issue from crevices in the lava beds and 

some of them discharge several hundred second-feet. Fall River is fed 

by large springs about 10 miles above its mouth, which discharge 

approximately 1,500 second-feet. Hat and Burney creeks are fed 

largely by springs, and McCloud River draws heavily from numerous 

large springs on the southern slo'pe of Mount Shasta. Most of the 

smaller tributaries are also spring fed.

COTTONWOOD CREEK.

Cottonwood Creek has three principal forks North, Middle, and 

South forks. North Fork rises in Bully Choop Mountain, which 

reaches an elevation 7,073 feet above sea level, is about 20 miles
STKEAM MEASUBEMENTS IF SACRAMENTO BASIN. 17

long, drains an area of 112 square miles, and has a total fall of about 

4,200 feet. It unites with Middle Fork a short distance below Gas 

Point. Middle Fork is about 30 miles long, has a fall of 5,900 feet, 

and drains an area of 261 square miles. South Fork rises in the 

Yolla Bolly Mountains, which reach an elevation about 6,000 feet 

above sea level, and unites with the main creek a few miles west 

of the town of Cottonwood; it is about 45 miles long, drains an area 

of 395 square miles, and has a fall of 4,600 feet. The main creek 

flows eastward and empties into the Sacramento about 5 miles 

east of the town of Cottonwood and opposite the mouth of Battle 

Creek. The total drainage area is 929 square miles.

The crest of the Coast Range, which forms the western boundary 

of the basin for a distance of about 50 miles, ranges in elevation from 

6,000 to 8,000 feet above sea level. From the crest toward the east, 

the basin slopes rapidly to the foothills around the north end of 

the Sacramento Valley, and is regularly furrowed by numerous 

drainage ways. About two-thirds of the area is more than 1,000 

feet above sea level.

The basin is well timbered, but at the lower elevations the growth 

is more or-less scrubby. The upper part of the basins of Middle 

and South forks is included in the Trinity National Forest.

The mean annual precipitation ranges from 25 inches in the lower 

part, where it occurs as rainfall, to more than 50 inches along the 

crest of the Coast Range, where much of it occurs as snow.

Some irrigation on a small scale is carried on in this basin, especially 

in the northern part, along the North Fork, and there is opportunity 

for further development. Storage and power development are 

undoubtedly possible in this basin, but to what extent is not known.

STONY CREEK.

Stony Creek drains an area on the eastern slope of the Coast Range, 

north of the Cache Creek basin and south of the basin of Thomas 

Creek, which lies between it and the Cottonwood Creek basin on the 

north. The total drainage area comprises about 828 square miles, 

of which about 600 square miles is embraced in an irregular parallelogram, 10 to 15 miles wide, that touches the crest of the range for a 

distance of 50 or 60 miles. The creek rises in the south end of this 

area and flows northward along its eastern border about 35 miles, 

then northeastward about 15 miles, and finally southeastward to its 

junction with the Sacramento near St. John. The creek is about 90 

miles long and its fall is 4,000 to 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, Grind-^ 

stone Creek from its north end, and North Fork, which enters the 

main creek about 10 miles northwest of Orland, 

49685° WSP 298 12 2
18 WATER RESOURCES OF CALIFORNIA PART I.

The drainage basin of Stony Creek is somewhat peculiar, topographically and geologically. The main stream lies wholly in sedimentary 

rocks; the tributaries from the west come from the granitic crest of 

the range and have heavy gradients. At various points in the basin 

the streams intersect conglomerate ridges which, because of their 

resistance to erosion, have produced favorable sites for dams and 

reservoirs (PL II, A). The basin ranges in elevation from a few 

hundred feet in the valley to 6,000 feet or more at the summit of the 

range.

The basin is covered with a good growth of grass and dense brush at 

the lower elevations and heavy, commercially valuable timber on the 

mountain summits. About three-fourths of the upper basin is 

included in a national forest reserve.

The mean annual precipitation ranges from 18 inches in the valley 

to 40 inches or more on the mountain summits, where more or less 

of it occurs as snowfall. The heaviest freshets occur during the 

winter.

For years this creek has been used as a source of water for irrigation 

on a small scale in the northeastern part of Glenn County. The 

United States Reclamation Service now has under construction the 

Orland reclamation unit, which will take water from Stony Creek 

to irrigate 14,000 acres around Orland.

The most important reservoir sites on the main stream and its 

tributaries were surveyed several years ago by the United States 

Geological Survey. 1 Without storage only a comparatively small 

amount of power could be developed continuously in Stony Creek 

basin; with a comprehensive storage system many thousand horsepower could be developed.

CACHE CREEK.

The Cache Creek drainage basin lies on the eastern slope of the Coast 

Range in Lake, Colusa, and Yolo counties, immediately south and 

west of the south end of the Stony Creek basin and north of the Putah 

Creek basin. The upper part of the area, comprising about 824 

square miles, lies in the central part of Lake County, south of the 

divide separating the Eel River and Cache Creek basins. It is 

roughly rectangular in shape, and contains Clear Lake in its center. 

From Lake County the basin extends southeastward to the Sacramento Valley as a strip about 50 miles long and 10 miles wide. The 

total area of the basin is 1,290 square miles.

Cache Creek is the only known outlet of Clear Lake. The lake is 

very irregular in shape and has an area of 65 square miles and an 

elevation of 1,325 feet at mean level. Its length is 20 miles and its

greatest width 7 miles. The upper part, or main lake, has a maximum 

depth of 35 feet, but the lower neck has a few small areas as much as 

50 feet in depth. The drainage area tributary to the lake is about 

417. square miles, chiefly toward the south and west. The principal 

creeks flowing into the lake are Scotts, Middle, and Clover from the 

west, and Doba, Kelsey, and Cole* from the south. They are torrential during the rainy season, but are practically dry in the summer.

From the lake Cache Creek flows southeastward to Yolo basin and 

ultimately 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 important tributary is Bear Creek, which 

drains the western part of Colusa County. These creeks are very 

small in the summer, but rarely become dry. All the tributaries are 

torrential during the rainy season.

The upper part of the Cache Creek drainage basin in Lake County 

is mountainous and very rugged. Some of the peaks reach an altitude of 6,000 feet above sea level, and their slopes, as well as those of 

the lower ranges, are very steep. About 5 miles below the outlet the 

creek enters Cache Creek canyon, in which it flows for 25 miles on an 

average grade of 35 feet to the mile. In some places the canyon walls 

are vertical cliffs 300 feet high. Below the canyon the creek enters 

Capay Valley, from 1 to 3 miles wide and 20 miles long, through which 

it winds for a distance of nearly 30 miles before entering the Sacramento Valley.

On the northern slope of the ranges around Clear Lake are fine belts 

of fir, oak, and pine. Elsewhere on the high ranges the vegetation 

consists of a dense growth of greasewood and chaparral. A strip 

along the northern edge of the basin is included in a national forest.

The mean annual precipitation ranges from 17 inches in the Sacramento Valley to 40 inches or more on the mountainous summits in 

Lake County, where much of it occurs as snowfall in the winter season.

Cache Creek furnishes exceptional opportunities for irrigation development in Yolo County. At the present time many ditches take 

water from the creek for irrigating land in the vicinity of Woodland 

and Yolo.

Good storage sites ate also available in this basin. Clear Lak.e is a 

natural storage reservoir which is very powerful in regulating Cache 

Creek.2

The opportunities for water-power development on Cache Creek are 

excellent.

The upper part of this basin contains springs, a number of which, 

especially in the North Fork basin, have medicinal properties that attract hundreds of visitors during the summer. Bartlett Spiings are 

probably the best known.

FEATHEE RIVER AND ITS TRIBUTARIES. 

THE MAIN STREAM.

Feather River heads on the crest of the Sierra and takes a general 

southwesterly course to its junction with the Sacramento about 30 

miles south of Marysville and about 15 miles northwest of Sacramento. 

It is about 175 miles long 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 basin of American River.

The basin is roughly triangular in shape and is naturally subdivided 

into three other comparatively large basins: North Fork basin at the 

north and west, with a total drainage 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 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 continuation of the main stream, includes the eastern part of Butte, the 

greater part of Plumas, and the southwestern corner of Lassen counties. In length the 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 5,000 feet above sea level. Beckwith 

Pass, which opens into this valley from the east, is the lowest pass in 

the Sierra Nevada, its elevation being 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. The Middle Fork unites with the North Fork in Butte County, 

about 6 miles northeast of Oroville.

Above Prattville are two small basins of almost equal size, the eastern being drained by Hamilton Branch and the western by North 

Fork. The eastern basin ranges in elevation from 4,300 to 7,500 feet, 

has an area of 230 square miles, and includes the East Arm of Big 

Meadows and the large level area called Mountain Meadows. The 

western basin Has an area of 245 square miles, ranges in altitude from 

4,300 to 10,000 feet above sea level, and includes the West Arm of Big 

Meadows and the higher elevations about Lassen Peak. Hamilton 

Branch unites with North Fork about 3 miles east of Prattville, at the 

lower end of Big Meadows.

J>

The greater part of the Feather River basin is rough and mountainous and the slopes are deeply trenched by numerous stream 

channels. The rocks in the southern and eastern parts of the basin 

are principally granites; at the lower elevations some porous and 

deeply eroded slates and lavas are also found. The northern part of 

the basin is characterized by cones, craters, deposits of volcanic ash, 

and lakes, which indicate recent volcanic activity. The soil of the 

basin is porous, absorbs moisture readily, and serves to equalize the 

stream flow. The numerous meadows and valleys that exist in 

different parts of the area also help to maintain a steady flow in the 

streams during the dry season.

The basin is well forested. On the lower elevations the growth 

consists for the most part of brush and scrubby timber. The mountain sides, except around the summits of the highest peaks, like Lassen, 

are covered with merchantable timber. About two-thirds of the 

entire basin, 4,300 square miles in round numbers, is inclosed in 

national forest reserves, which include all the upper part of the basin 

except Sierra Valley on Middle Fork,'the meadows around Prattville 

on North Fork, and a few other very small valleys.

The mean annual precipitation in the Feather basin is about 30 

inches in the foothill belt, and increases toward the mountain summits. 

It ranges from 40 to 60 inches in the North and Middle Fork basins at 

the north and east, and from 40 to 75 inches at the Yuba basin at the 

south. In the winter much of it occurs as snowfall which does not 

disappear from the summits until summer.

Very little irrigation is practiced in the Feather basin, though some 

water is diverted for use in the small valleys and in the Sacramento 

Valley below the foothills. Considerable water is used for mining and 

power.

The basin affords many excellent storage sites, especially on the 

North and Middle forks. Surveys of a large number of reservoir sites 

in this area have been made by the United States Reclamation 

Service and many others have been made by private companies.

The minimum flow of the streams in the Feather River basin is 

sufficient to develop more than half a million horsepower, and this 

amount could be .almost doubled with storage. On North Fork alone 

about 300,000 horsepower could be developed at low water, and with 

storage half a million would be available. On Middle Fork only about 

66,000 could be developed at low water, and on Yuba River only about 

130,000. At the present time the Great Western Power Co. is engaged 

in developing sites in the North Fork basin (PL III, B}.

The basin has many large springs, especially in the lava districts, 

which supply a more or less steady flow throughout the year. In 

the North Fork basin, especially, are large perennial springs discharging 50 to 100 second-feet. One of the largest, Dotta Spring,
22 WATER RESOURCES OF CALIFORNIA PART I.

about 3 miles east of Prattville, has a maximum discharge of 100 

second-feet and a minimum of 70 second-feet. Many perennial 

springs are also found in the Yuba basin. The Feather basin also 

contains many small glacial lakes, chiefly in Yuba and North Fork 

basins.

YUBA RIVER.

Yuba River rises near the crest on the western slope of the high 

Sierra and flows southwestward 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 has an area 

of more than 1,300 square miles and is triangular in shape, the base of 

the triangle lying along the crest of the Sierra. Its extreme length 

from the mouth of the Yuba River to the crest of the Sierra is about 

70 miles, and its greatest width is about 35 miles. The river is 

formed by three principal forks Middle, North, and South. The 

Middle Fork, which is considered the continuation of the main 

stream, rises in Sierra and Nevada counties on the west and south 

slopes of Weber Peak and takes a general southwesterly course. It 

receives the North Fork in Yuba County, in the northeastern part of 

T. 17 N., R. 7 E., and the South Fork in Nevada County, in the 

southwestern part of T. 17 N., R. 7 E.

The topography of the Yuba basin is rugged and mountainous. 

From the edge of the Sacramento Valley the surface rises gently 

through the foothills and then more abruptly through rounded and 

broken mountains to the crest of the Sierras, which along the YubaTruckee divide has a mean elevation of about 8,000 feet and a few 

peaks exceeding 9,000 feet. The streams have cut deep canyons 

which head well up in the mountains. Slates and kindred rocks, 

much eroded, are found in the lower western part of the basin; in the 

higher eastern part the rocks are granites and lavas. A stratum of 

serpentine traverses the basin parallel to the crest but at a considerable 

distance from it.

The soil is deep in most places and supports a hardy growth of 

brush and timber, especially along the sides of the canyons. The 

North Fork basin has at present the best forest cover, and that of 

South Fork the poorest, but this difference is the result of lumbering 

operations. All the upper part of the Yuba basin, more than 800 

square miles, is now included in a national forest.

The mean annual precipitation ranges from 18 inches at Marysville to about 70 inches near the mountain crest. In the upper and 

central parts of the basin the precipitation ranges from 50 to 70
STREAM MEASUREMENTS IN SACRAMENTO BASIN. 23

inches and occurs principally as snow, which remains on the ground 

all winter and well into the summer. The North and South Fork 

basins probably receive the greatest precipitation.

Little irrigation is practiced in the Yuba River basin, but the 

main stream could undoubtedly be used for irrigating a part of the 

Sacramento Valley.

Storage sites in the Yuba River basin are not numerous, though 

considerable storage is feasible, particularly along the upper part of 

South Fork. Numerous small lakes near the headwaters of the 

South Fork are utilized as storage reservoirs. The stored water was 

originally used in hydraulic mining. At present this water is used 

for irrigation along the foothill fruit belt in the vicinity of Auburn 

and also for power development. The minimum flow of the streams 

is sufficient to develop about 1'25,000 horsepower without storage.

The principal power development on the Yuba River is that of the 

Pacific Gas & Electric Co. at its Colgate plant, about 12 miles above 

the gaging station at Smartsville. The water is diverted from North 

Fork below Bullards Bar.

Perennial springs are found in different parts of Yuba River basin, 

particularly along the North Fork. In the South Fork basin at the 

higher elevations are many small glacial lakes, and here also are 

many rounded, denuded summits and glacial valleys.

The channel of Yuba River for many miles above its mouth has 

been filled with enormous quantities of mining de"bris tailings from 

hydraulic mining. The depth of this de"bris is about 7 feet at the 

mouth, about 26 feet at Daguerre Point, 11 miles above the mouth, 

and about 84 feet in The Narrows, 18 miles above the mouth. An 

attempt has been made to restrain this de"bris from moving downstream b'y building barrier dams, but it has not been successful.

INDIAN GREEK.

Indian Creek rises in the Sierra divide and flows westward to its 

junction with North Fork of Feather River. The stream is about 

50 miles long and its drainage area, comprising 733 square miles,1 

is much greater than that of North Fork above the junction of the 

two streams. The basin is in the northeastern part of Plumas 

County, north of Middle Fork of Feather River and east of the upper 

par^t of North Fork. For about 45 miles it lies along the Sierra 

divide, which separates it from Honey Lake drainage basin at the 

east. The principal tributaries are Squaw, Red, Clover, Little 

Grizzly, and Spanish creeks from the south and Light and Wolf 

creeks from the north.

Practically all of the Indian Creek basin has an altitude exceeding 

5,000 feet, and much of it is a lava formation 6,000 to 7,000 feet in

i Fourth Ann. Rept. U. S. Reel. Service, 1906, p. 93.
24 WATER RESOURCES OF CALIFORNIA PART I.

altitude. The entire basin is included in a national forest reserve, 

except a few meadows, of which Indian and American valleys are 

the largest.

The mean annual precipitation is between 40 and 45 inches, and a 

large part of it occurs as snowfall. During the winter the streams 

freeze over occasionally.

The basin affords several good storage reservoir sites. Opportunities for power development are also good. With the available 

fall, the flow of the streams is sufficient to generate at least 20,000 

horsepower continuously, and by utilizing storage 60,000 horsepower could be developed.

BEAR RIVER.

Bear River drains a narrow strip on the western slope of the Sierra 

below elevation 5,500 feet. The basin is aboat 60 miles long and not 

more than 10 miles wide, and lies south of Yuba River basin and 

north of American River basin. Its total area is less than 300 square 

miles.

The river rises in the extreme northeastern part of the basin near 

Emigrant Gap, and flows southwestward 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.

The Bear River basin has very little forest, except on a small area 

in the upper part. The mean annual precipitation ranges from 21 

inches in the valley to 52 inches at the source of the river, where 

much of it occurs as snow that soon disappears.

Some irrigation is practiced in this basin. Storage is not feasible, 

and the minimum flow of the streams is not sufficient to develop 

much power.

AMERICAN KIVEK.

American River drains the area lying on the western slope of the 

Sierra, south of the Bear and Yuba River basins, west of Lake Tahoe 

and the Truckee River basin, and north of the Cosumnes and Mokelumne River basins. The area is triangular in shape, about 80 miles 

long, and has a maximum width of 50 miles along the crest of «the 

Sierra, and its total area is about 2,000 square miles.

American River is formed by the union of its three principal forks 

and flows southwestward about 110 miles to its junction with the 

Sacramento just above the city of Sacramento. North and Middle 

forks are about 60 miles long, with a fall of nearly 8,000 feet and 

drain areas measuring, respectively, 349 and 640 square miles.
STEEAM MEASUREMENTS IN SACRAMENTO BASIN. 5

South Fork, about 60 miles long, falls nearly 9,000 feet and drains an 

area of 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.

Almost half of the American drainage basin exceeds 5,000 feet in 

altitude and probably one-third of it ranges from 6,000 to 9,000 feet. 

The rocks of the upper part are chiefly granites, which have yielded 

to glacial and erosional action to such an extent as to form many 

regular ridges and drainage channels.

The lower elevations of the basin are barren or sparsely timbered, 

but the nigher elevations support a good growth of timber. All the 

upper part of the basin, amounting to considerably more than half 

of the total, is included in a national forest.

The mean annual precipitation ranges from 21 inches in the Sac* 

ramento Valley to probably 60 inches near the summit of the Sierra, 

where it occurs as snow which does not disappear till summer. In 

the foothill region it ranges from 25 to 30 inches and in the central 

region from 45 to 55 inches. It is probably somewhat greater in the 

northern than in the southern part of the basin. At the higher altitudes there is much snow and ice during the winter.

Some water is diverted from the American for irrigation, particularly in the Sacramento Valley, but further development is possible.

Storage on a big scale is not possible in the American basin, though 

considerable storage for power and mining is feasible, particularly on 

Middle and South forks.

American River is also the source of the water supply of the city 

of Sacramento.

The minimum flow of the streams in this basin, with the existing 

fall, is sufficient to develop about 100,000 horsepower without 

storage, of which about 40 per cent is on the South Fork and nearly 

30 per cent on the Middle Fork.

The upper part of the American basin shows evidence of glaciation, 

which has left many small lakes, some ,of which have been dammed 

and used for storage in connection with mining.

PUTAH CREEK.

The Putah Creek basin lies 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 Solano counties. The basin is 

rather long from northwest to southeast and comparatively narrow, 

being about 20 miles wide at the north and less than 10 miles at the 

east. It has a total area of about 810 square miles.
26 WATER RESOURCES OF CALIFORNIA PART I.

Putah 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 

practically dry during the summer. The chief tributaries are Soda 

Creek from the north and Pope Creek from the west.

The topography of the Putah Creek basin is very rugged. Much 

of the upper basin is rough and precipitous. The underlying rock is 

an impervious slate and serpentine with only a thin soil covering. 

There is very little tilled land in the basin except below the foothills. 

Altitudes range from about 100 feet in the valley to about 5',000 feet 

on the mountain summits.

The lower parts of the basin are comparatively barren of timber, 

though they support a considerable growth of grass and brush which 

extends down as far as the foothills. At moderate elevations timber 

grows scatteringly, and the mountain summits are covered by a 

fairly heavy timber growth. ' '

The mean annual precipitation varies widely in the different parts of 

the basin. Along the foothills it averages about 28 inches, in the 

central part about 40 inches, and along the crest of the divide, where 

some of it occurs as snowfall in the winter, about 65 inches. Helen 

Mine, on the northern slope of Mount St. Helena, receives almost 100 

inches annually.

Below the foothills is a large area of rich irrigable land, which 

could be supplied with water from Putah Creek. Some of this lancl 

is already irrigated and has been proved to be susceptible of the 

highest state of cultivation.

At least two good reservoir sites exist on the main stream, one near 

Winters and the other near Guenoc.

Only a small amount of power could be developed continuously in 

the Putah Creek basin without storage because of the torrential 

nature of the streams. By utilizing the storage sites, however, many 

thousands of horsepower could be developed.

CLIMATE AND VEGETATION.

PRECIPITATION.

With all its great diversity of climate, ranging from torrid heat to 

arctic cold, from aridity to heavy rainfall and equally heavy snowfall, 

one climatic characteristic is common to all parts of California there 

is a wet and a dry season, corresponding to the cold and warm, seasons 

of the Atlantic coast States. Of the annual precipitation in the Sacramento basin 83 per cent, or five-sixths of it, comes in the months 

November to April, inclusive.
STEBAM MEASUREMENTS IK SACBAMENTO BASIN. 27

The cause of this unequal distribution of precipitation lies in the 

presence of the Pacific Ocean and the direction of the prevailing 

winds. Water receives heat and parts with heat more slowly than 

the land. Hence in the same latitude the sea-is warmer than the land 

in winter and cooler in summer. Moreover, with its currents, tides, 

and waves, the sea maintains a more uniform temperature in different 

latitudes than does the land. The prevailing " westerlies" come from 

the Pacific laden with moisture. When such air currents reach a 

land which is cooler than they are, as happens in the winter season, 

they are chilled below the point of saturation and a part of their 

moisture is dropped as rain or snow. If, on the other hand, they 

meet a land warmer than they are, as is the case commonly in 

summer, they flow over it with little loss of moisture.

The mean relative humidity of the atmosphere , 4 

for the year in the Sacramento Valley ranges from 

69 per cent at Sacramento 3 

to 57 per cent at Red I

part of the valley to 25

inches in the northern part; in the foothills and mountain area it 

ranges from 20 to 60 inches with an occasional year of over 100 

inches. Snow begins to accumulate on the mountains in November 

and reaches a maximum depth of packed snow in March, when it 

begins to melt. Melting continues until the middle of June or first 

part of July. The storage of precipitation in the form of snow has 

had a great effect on the flow of streams, those streams that head 

in the crest of the high mountains having a much larger flow during June, July, and August than those that head at a lower altitude. 

The mean monthly precipitation in this valley determined from 

records at 18 places in it is shown in figure 1. January is the wettest 

month, having an average precipitation of about 4 inches. December 

has a little less than 3.5 inches. February and March have each a 

little less than 3 inches. The months of June, July, and August are 

almost rainless. The total for the six months April to September is
28 WATER RESOURCES OP CALIFORNIA PART I.

about 3.4 inches and for the six months October to March it is about 

16.9 inches.

The annual precipitation at Sacramento for the 60-year period 

September, 1849-August, 1909, is shown in figure 2. Each 12-month 

period extends from September 1 of one year to August 31 of the 

following year. The mean for the 60 periods of 12 months each is 

19.61 inches. It may be noted that there is a variation in the precipitation of these 12-month periods, or years, from 4.71 inches per 

year to 36.36 inches. The maximum precipitation is 1.85 times the 

mean for the 60 years and the mean is 4.16 times the minimum. The 

precipitation is above the mean for 27 years and below the mean 33 

years. Every fifth or sixth year is very dry, and there are periods 

of 8 years when the precipitation is each year below or very little 

above the normal. There may be two very dry years in succession.

FIGURE 2. Precipitation at Sacramento, Cal., September, 1849, to August, 1909.

During the 55-year period 1849-1903 the greatest monthly precipitation at Sacramento was 15.04 inches in January, 14.2 inches in 

April, and 13.4 inches in December. The greatest in August the 

month of least precipitation was 0.20 inch. The smallest monthly 

precipitation during this period was 0.15 inch in January, 0.04 

inch in February, 0.04 inch in March, and 0.0 or a trace each of the 

other nine months of the year. Fourteen times during these 55 years 

the hourly rate has been greater than 0.20 inch; three times the 

hourly rate has been greater than 0.40; and once it was 1 inch per 

hour for two hours.

The total rainfall in 24 hours or less has been 2 inches on nineteen 

occasions, 4 inches on four occasions, and 7.24 inches in 22 hours on 

one occasion. The increase of rainfall from Folsom, which is at the
STREAM MEASUREMENTS IN SACRAMENTO BASIN. 29

eastern edge of the Sacramento Valley, to Coif ax, is more than 1 inch 

per hundred feet rise in elevation, but increase, however, is variable 

for different storms. The rainfall at Sacramento (71 feet above sea 

level) during February, 1904, was 5.26 inches, or 70 per cent in excess 

of the normal; at Folsom (252 feet above sea level) it was 7.19 inches, 

or 100 per cent in excess of the normal; at Coif ax (2,421 feet above 

sea level) it was 20.10 inches, or 303 per cent in excess of normal.

TEMPER ATTIRE.

The mean annual temperature is 60° at Sacramento and 63° at 

Red Bluff (fig. 3). These stations represent fairly well the valley 

portion of the Sacramento basin in this respect. On the mountains 

east and west of the valley temperatures are lower; at Summit, 

for example, 7,000 feet 

above sea level, the 

mean annual temperature is 42°.

At Sacramento the 

mean summer temperature is 72°; that of winter 47°. In the warmest 

month, July, the mean 

temperature is 74°; in 

the coldest month, January, it is 46°. The

lowest 19°, showing an 

extreme range of 89°. 

These figures characterize the temperatures of the valley. The 

extreme temperatures of the mountainous portions of the area 

are characterized by the conditions at Summit. The mean summer 

temperature here is 58° and that of the warmest month, July, 61°; 

the mean winter temperature is 29° and that of the coldest month, 

January, is 28°. The highest temperature on record is 98°, and the 

lowest 12°, a total range of 110°.

Although the prevailing winds of California are westerly, the 

highly accented topography of the State locally modifies or changes 

the direction of the wind. The Sacramento basin, being sheltered 

by high coast ranges, is little affected by the sea breeze, which 

apparently gets but a short distance inland, and not infrequently 

it is visited by "northers" hot dry winds from the north which 

injure ripe fruit and wheat seriously. They occur most frequently 

in May, June, and July. Thunder storms and tornadoes are almost 

unknown in the valley.
30 WATEE EESOUECES OF CALIFOBFIA PART I.

FOBESTS.

The mountain and foothill slopes of the Sacramento basin are in 

general well forested. Coniferous trees constitute by far the greater 

portion of the forest growth, and oaks, ash, maple, mountain mahogany, aspen, cottonwood, California buckeye, western redbud, willows, 

alders, and other deciduous species the remainder. Much of the 

forest land is now held as national forests, but skirting the reserves 

are large areas of privately owned timber lands, extending from the 

Shasta National Forest on the north to the1 Stanislaus Forest on the 

south and containing probably over a million acres.

In the reserved lands are 11,451,565 acres of woodland, comprising 

the Shasta, Lassen, Plumas, Tahoe,1 Stanislaus, Sierra, and Sequoia 

national forests. It is estimated 2 that these national forests contain 

53,961,213,000 feet b. m. green saw timber, as well as about 35,000,- 

000 feet cordwood and over 375,250 feet dead saw timber. The 

private timber claims within the limits of the national forests mentioned contain about 28,542,350,000 feet b. m. merchantable timber.

POPULATION AND INDUSTRIES.

Twenty counties lie wholly or in part within the Sacramento River 

basin. The following table shows the population of these counties,

engineers of the Geological Survey by means of a current meter 

(PL IV), which is operated from a bridge, a car suspended on a cable, 

or a boat, or by wading, the method adopted depending on the 

location of the station (Pis. V and VI).

By plotting the results,of measurements, using the cischarges and 

corresponding gage heights as coordinates, rating curves are drawn 

from which a rating table giving the flow for any gage height can be 

prepared. From these rating tables and the daily gages heights daily 

estimates of flow are computed.

More detailed description of the methods used in ijollecting and 

preparing these data for publication may be found in the introductory 

sections of Water-Supply Paper 271, "Surface water supply of California, 1909." 2

DEFINITION OF TERMS.

The volume of water flowing in a stream the "ruii-off" or "discharge" is expressed in various terms, e&ch 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 jin second-feet 

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

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

32 WATER RESOURCES OF CALIFORNIA PART I.

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

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

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

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

wide, 1 foot deep, at a rate of 1 foot 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.

"Miner's inch" represents & rate of flow and varies in different

States, as noted in the table of convenient equivalents (p. 36). In

California it was legalized by an act approved March 23, 1901, as one-

. fortieth of a second-foot. Prior to the passage of this act the common

usage was one-fiftieth of a second-foot. The act reads as follows:

SECTION 1. The standard miner's inch of water shall be equivalent or equal to one 

and one-half cubic feet of water per minute, measured through any aperture or orifice.

SEC. 2. All acts or parts of acts inconsistent with the provisions of this act are hereby 

repealed.

SEC. 3. This act shall be in effect and force sixty days from and after its passage. *

"Run-off in inches" is the depth to which the drainage area would 

be covered if all the water flowing from it in a given period were 

conserved and uniformly distributed on the surface. It is used for 

comparing run-off with rainfall, which is usually expressed in depth 

in inches.

An "acre-foot" is equivalent to 43,560 cubic feet, and is the quantity required to cover an acre to the depth of 1 foot. The term is 

commonly used in connection with storage for irrigation.

EXPLANATION OF DATA.

The order of treatment of stations dn this paper is downstream. 

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.

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, 

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

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

STEEAM MEASUREMENTS IN SACRAMENTO BASIN. 33

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, gage height in feet, 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. Theigage 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 the readings shall not be of negative values.

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. In general 

rating tables are 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 takea 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 crosssection 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. These 

values should be so adjusted that the first differences shall always 

be increasing or constant, except for known conditions of backwater.

34 WATEE BESQVKQES OF CALIFOKNIA PABT I.

The table of daily discharge gives the discharge in second-feet 

corresponding to the observed gage heights as determined from the 

rating tables.

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

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

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

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

the water surface was at crest height and the corresponding discharge 

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

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

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

during the month. On this the computations for the remaining 

columns, which are defined on page 32, are based.

ACCURACY AND RELIABILITY OF FIELD DATA AND COMPARATIVE

RESULTS.

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

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

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

degree of permanency of channel and of permanency of the relation 

between discharge and stage.

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

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

due to misinterpretation of stage and flow data.

In order to give engineers and others information regarding the 

probable accuracy of the computed results, footnotes are added to 

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

tables used, and an accuracy column is inserted in the 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.

Even though the monthly means for any station may represent 

with a high degree of accuracy the quantity of water flowing past the
STEEAM MEASUREMENTS IN SACKAMENTO BASIN. 35

gage, the figures showing discharge per square mile and depth of 

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

including in the measured drainage area large noncontributing districts or omitting estimates of water diverted for irrigation or other 

use, and they should, therefore, be considered as only approximate, 

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

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

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

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

needs the results of the computations. The table of monthly discharge is so arranged as to give only a general idea of the flow at 

the station and should not be used for other than preliminary estimates. The determinations of daily discharge allow more detailed 

studies of the variation in flow by which the period of deficiency may 

be determined.

It should be borne in mind that the observations in each succeeding year may be expected to throw new light on data already collected and published, and the engineer who makes use of the figures 

presented in these papers should verify all ratings and make such 

adjustments for earlier years as may seem necessary.

STATION RECORDS. 

SACRAMENTO RIVER AT CASTELLA, 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 half a mile 

above the station.

The gage is a vertical staff on the downstream end of the bridge 

pier near the right bank.

Beginning March 8, 1912, discharge measurements were made at a 

highway bridge half a mile below the gage. Prior to this date they 

were made at the bridge at the gage.

SACRAMENTO RIVER AT JELLYS FERRY, CAL.

This station was established April 29, 1895, at Jellys Ferry, 12 miles 

above Red Bluff, CaL, and was maintained until June 30, 1902, when 

it was discontinued in favor of the Red Bluff station in Iron Canyon, 

where better measuring conditions existed.

The river is liable to overflow its left bank at a gage height of 25 

feet. The bed of the river is of gravel and is fairly permanent. A 

rapid occurs about one-half mile below the station. No canals of 

importance are taken out above. The gage heights are affected by 

the contraction of the river in Iron Canyon, some miles below. This 

causes, during high stages, a wide fluctuation on the gage at Jellys 

Ferry.

The gage, which is located at the ferry, consists of a vertical rod in 

three sections nailed to trees.

Auxiliary gages placed above and below the cable were used to 

determine the slope of the water surface. The gage datum remained 

unchanged during the life of the station. The gage was read twice 

a day.

Measurements were made from the ferry boat, held in place by the 

ferry cable. Beginning in 1896, high-water measurements were made 

from a car attached to the cable. During 1897 to 1899 the ferryman 

made frequent measurements. In the revision of the data for this 

report only those measurements made by the hydrographers of the 

Geological Survey have been used in the development of the rating 

curve. Monthly estimates for the entire record have been recom-
STEEAM MEASUREMENTS IN SACRAMENTO BASIN. 45

puted on the basis of a fairly well defined rating curve which averages 

these measurements. The original current-meter notes and the meter 

rating tables have been examined and measurements recomputed 

when necessary.

The maximum crest discharge recorded at this station was 166,000 

second-feet, for a gage height of 35.5 second-feet, February 25, 1902. 

This maximum has been far exceeded since records have been kept 

at Iron Canyon.

The lowest discharge recorded was 4,200 second-feet, September 6 

to 22, 1901. Lower discharges have since been recorded at Iron 

Canyon.

NOTE. This table is not applicable for obstructed channel conditions. It is based mainly on discharge 

measurements made during 1895 to 1901 byhydrographersof the U. S. Geological Surveyand is fairly well 

denned. Some of the measurements have been revised from a study of the original notes and the meter 

ratings. It is believed that this revised curve is fairly representative of the discharge during the period 

covered.

NOTE. Drainage area changed from 9,130 square miles to 10,200 square miles to include Goose Lake 

Basin, which is naturally a part of Sacramento River Basin.

SACRAMENTO RIVER NEAR RED BLUFF, CAL.

This station was established January 28, 1902, 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 previously 

used for stream gaging by the State engineer in 1879, and by the 

commissioner of public works in 1893 to 1894. Discharge measurements were begun in 1901 before the station was regularly established. 

The river at this point has a direct course 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 of about 700 feet span, which is anchored in the lava rock 

which forms the wall of the canyon (PL VII). The data collected are 

useful in connection with the maintenance of navigation below Red 

Bluff and in the consideration of reclamation problems in Sacramento 

Valley.

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
56 WATER RESOURCES OP CALIFORNIA PART I.

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.

The flow at the station is not affected by artificial storage. With 

the exception of a small amount of water diverted for irrigation 

from some of the minor tributaries the record at this station gives 

the natural run-off from this drainage basin.

The gage used by the commissioner of public works was still in 

place at the cable location and was used from January 28, 1902, the 

date upon which observations were begun, until December 31, 1903. 

A second set of gage rods were 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 these gage rods were removed' to a 

point on the left bank about 4,000 feet below the measuring section 

and read until February 12, 1906. Since February 14, 1906, the 

cable gage has been read. By synchronous readings of these lower 

gages with that at the cable all readings have been reduced to equivalent readings for the cable gage. The datum of the cable gage has 

remained unchanged. This gage is located in lot 4, sec. 34, T. 28 N.,

In revising the data for this report the gage heights have been compared with the original gage books and corrections made where necessary. The maximum crest discharge recorded since 1902 was 278,000 

second-feet for a gage height of 35.2 feet February 3, 1909. The 

flood of February 16, 1902, reached a gage height of about 31 feet 

during the night, the corresponding discharge being 224,000 secondfeet. The crest discharge of the flood of 1907, as nearly as can be 

determined, was 204,000 second-feet for a gage height of 29.4 feet 

at 5 p. m. March 20, 1907. The lowest recorded discharge 3,980 

second-feet lasted from September 7 to 28, 1903.

SACRAMENTO RIVER AT RED BLUFF, CAL.

The United States Weather Bureau has maintained a record of gage 

heights on Sacramento River at the highway bridge in Red BluflF, 

CaL, since December 15, 1878.

During 1894 to 1896 the United States Geological Survey attempted 

to develop a rating curve for this station in the hope of utilizing these
72 WATEE BESOITBCES OF CALIFOENIA PABT I.

long-time records, and to that end made several discharge measurements but with unfavorable results.

The Weather Bureau gage is located at the east end of the bridge 

from which the discharge measurements were made. The measuring 

section is badly broken by piers and the current is very swift. With 

the type of meter then used it was found impossible to accurately 

record the number of revolutions at flood stages, and the presence of 

piers greatly interfered with the accuracy of the results obtained. 

The United States Geological Survey abandoned this station in 1896 

in favor of a new location at Jellys Ferry, where more favorable measuring conditions existed.

SACKAMENTO KIVEE AT COLLINSVILLE, CAL. 1

The flow of Sacramento River at Collinsville, the point of its junction with the San Joaquin and entry into Suisun Bay up to 1886 had 

never been directly measured. Its flow past the city of Sacramento, 

57 miles above, had been determined by a number of low, mediumstage, and flood-water measurements in 1879 and 1880, and by lowwater measurements in 1885; and its fluctuations noted by daily rod 

observations from October, 1878, to 1886; occasional examinations 

of the channel were made in the interim.

From the results of the measurements a scale of discharge was projected for the channel at Sacramento, giving the probable quantity 

of water flowing for each foot of elevation of surface from lowest to 

highest observed stage. These deduced data, applied to the results 

of the daily rod observations, averaged generally for five-day or 

longer periods when the river was not in an active state of fluctuation, 

have afforded the estimated volumes from which the total for each 

month, as given in the following table, was determined.

The flow as given in the table is an estimate of the total discharge 

of Sacramento River and tributaries passing Collinsville.

PIT EIVEE NEAE CANBY, CAL.

This station, which was located at the highway bridge 3| miles 

southwest of Canby, Cal., was established December 26, 1903, and 

discontinued December 31, 1905. It was below the junction of 

North and South forks and above the mouth of Ash Creek. Data 

at this station are of importance as showing the amount of water 

available for storage in the proposed Warm Springs Valley reservoir.

The channel is straight for 150 feet above and 200 feet below the 

station and the current is moderate at all stages. The banks are 

high and are not subject to overflow. The channel is regular and is 

not subject to much change.

The datum of the vertical staff gage remained unchanged during 

the life of the station.

Discharge measurements were made from the bridge. The station 

was not maintained for a sufficient length of time to obtain maximum 

and minimum discharge values.

STREAM MEASUREMENTS SACRAMENTO BASIN. 79

PIT RIVER NEAR BIEBER CAL.

This station, which is located about 12 miles south of Bieber, near 

Holabird's ranch, in the gorge near the dam site at the lower end of 

Big Valley, was established January 22, 1904, to determine the 

quantity of water available for storage in the proposed Big Valley 

reservoir. It was discontinued September 30, 1908. No large tributaries enter Pit River near the station. Ash Creek comes in from 

the east about 16 miles above. Horse Creek enters from the south 

about 4 miles below, and Beaver Creek enters from the south at 

Pitville, about 12 miles below. Fall River, one of the chief tributaries, 

enters about 15 miles below the station. No diversions are made 

immediately above the station. A large part of the flow of the stream, 

however, is undoubtedly lost by evaporation from the surface of the 

numerous swamp valleys through which the stream flows. Many 

of the valleys are flooded artificially through the summer season. 

Many filings on the water and applications of right of way over public 

lands in this basin have been made. Most of the rights, however, 

have not been improved.

The stream is under no artificial control above or below the station 

that will affect the accuracy of the records. The channel conditions 

are, however, not of the best. The bed is rocky and rough, though 

not subject to change, and the current is very sluggish at low stages. 

The gage was a heavy wooden rod fastened to a large bowlder on the 

right bank of the stream, and was read daily. No change in the gage 

datum was made. Discharge measurements were made from a car 

and cable.

During the winter ice extends out from the banks 10 to 15 feet, and 

may affect the flow. The records are fairly reliable.

The maximum recorded discharge was 27,500 second-feet for a 

gage height of 16.4 feet, March 19, 1907. The river goes practically 

dry at times during the summer of low-water years. The lowest 

month was September, 1905, with a mean discharge of 1.23 secondfeet.

a Discharge estimated for days on which gage height was not recorded.

NOTE. Daily discharge 1904 to 1908, except as indicated, determined from rating curves applicable as 

follows:

1904: Well defined between 110 and 5,600 second-feet. Below 110 second-feet the curve is poorly defined 

because of the poor conditions for measuring.

1905: Well denned between 270 and 2,300 second-feet.

1906: Well defined between 39 and 5,200 second-feet.

1907-8: Fairly well defined between 29 and 5,200 second-feet.

PIT RIVER AT HENDERSON, CAL.

This station, which is located at the ferry one-fourth mile above 

Henderson, in sec. 36, T. 37 N., R. 1 W., was established September 

28, 1910,
STREAM MEASUREMENTS IK SACRAMENTO BASIN. 87

Nelson Creek enters the river about half a mile above the station, 

and Kosk Creek about 1 mile below.

The gage is a vertical staff attached to an aider on the left bank 

100 feet below the ferry. Discharge measurements are made from 

a cable just above the ferry.

Sufficient discharge measurements have not been made to define 

the rating curve at medium and high stages. The gage readings for 

1911 are not entirely satisfactory and are withheld pending the 

development of a rating curve, when comparisons with the record 

of discharge at Ydalpom will aid in the proper interpretation.

PIT RIVER NEAR YDALPOM, CAL.

This station which is located at Silverthorne Ferry, in the N. W. J 

sec. 32, T. 34 N., K. 3 W., about 1£ miles southwest of Ydalpom, 

about half a mile below the mouth of Squaw Creek, about 4 miles 

above the mouth of McCloud Kiver, 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 Kiver may be determined.

The gage is a vertical staff on an ash tree on the left bank 350 feet 

below the ferry.
88 WATER EESOUECES OF CALIFORNIA PART I.

Discharge measurements are made from a boat a short distance 

above the ferry cable, until October 1, 1911, when a car and cable, 

were installed 50 feet above the ferry cable.

STBEAM MEASUREMENTS IN SACRAMENTO BASIN. 91

COTTONWOOD CREEK NEAR LAKEVIEW, OREG.

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., R. 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 carries water 

at high stages; both banks are wooded and are overflowed at flood 

times. The channel at the lower station is evidently permanent 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.

NOTE. Ice probably existed at this station from about Jan. 1 to Mar. 10,1911; effect on the relation of 

gage height to discharge was not great during January, but was considerable during February and March. 

There was also ice at station from Dec. 20,1911, to Jan. 13,1912. Corrections have been applied on many 

of the gage readings from Mar. 17 to May 17,1911, and Mar. 24 to May 28,1912, to allow for diurnal fluctuation of stage.

NOTE. Discharge Jan. 31 to Mar. 10,1911, corrected for effect of ice; mean discharge Mar. 1 to 10,1911, 

estimated at about 8 second-feet; discharge Dec. 20,1911, to Jan. 13,1912, estimated. The accuracy rating 

of the records at this station is lowered Dy the diurnal fluctuations in stage.

DREWS CREEK NEAR LAKEVIEW, OREG.

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., R. 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 

49685° WSP 298 12 7
98 WATER RESOURCES OP CALIFORNIA PART I.

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 has been read twice daily part of the time and the 

readings indicate that the diurnal fluctuation is not strongly marked 

except at extreme high stages. Some ice forms occasionally during 

the winter. 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, 1910 (station No. 2), determined from a curve fairly well defined between 

500 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.

Daily discharge Mar. 1, 1910, to July, 1911, determined from a rating curve well defined below 1,200 

second-feet. Dally discharge for days on which gage was not read Interpolated or roughly estimated from 

the record of discharge of Cottonwood Creek.

No correction ior effect of ice.

SOUTH PORK OF PIT RIVER NEAR IVY, CAL.

This station, which was located about 3 miles west of Ivy post 

office, below the outlet of Jess Valley, was established January 11, 

1904, and discontinued November 15, 1905, West Valley Creek 

enters the South Fork from the south about 6 miles below the station.

The gage was a vertical plank fastened to a tree on the left bank 

50 feet above the station, and was read only at times when discharge 

measurements were made, as it was impossible to get an observer on 

account of its isolated location.

Discharge measurements were made from a cable and car.
STEEAM MEASUBEMENTS IN SACBAMENTO BASIN. 103

The channel is straight for 200 feet above and 80 feet below the 

station. The current is sluggish at low water stage. The right 

bank is low and subject to overflow in high water. The bed of the 

stream is composed of earth and is filled with vegetation at low-water 

stage.

During the winter there is some ice in the river. Monthly estimates 

based on the measurements have been computed for 1904 and 1905 

and give a rough approximation of the run-off. They should be 

used with caution.

NOTE. These values were obtained by interpolation between discharge measurements and by hydrograph comparison with other Pit River stations. They are only an approximate estimate of the monthly 

flow and should "be used with caution.

WEST VALLEY CREEK NEAE LIKELY, CAL.

This station, which was located 7 miles east of Likely, Cal., at the 

outlet of West Valley just above its confluence with the South Fork 

of Pit River, was established January 7, 1904, and discontinued 

-December 31, 1905.

Discharge measurements were made by a car and cable. Favorable 

measuring conditions existed, but owing to the inaccessibility of the 

cable gage a rod gage was placed 2 miles upstream near a ranch 

house, where an observer could be obtained. Numerous springs and 

swamps appear in the valley between the section and this upper 

gage, so this gage, as read, is not considered a satisfactory index of 

the flow at the cable. It, however, gives a general idea of the fluctuations in the flow of the stream.

After July 1, 1905, measurements were made at the ranch house 

near the upper gage. They give a smaller discharge than at the 

regular station. The gage datum remained unchanged.
STREAM MEASUREMENTS IN SACRAMENTO BASIN. 105

Monthly estimates have been computed from the measurements

o The gage heights recorded in 1904 were unreliable and have not been republished. Monthly estimates 

of flow for 1904 are based on the discharge measurements and are only approximate. They should be 

used with caution.

* Monthly estimates for 1905 are better than for 1904. Accuracy value for 1905 may be classed as follows: 

January to August, B; September and'October, C; November and December, D.

ASH CEEEK AT ADIN, CAL.

J*his station, which was originally located one-fourth mile above 

the town of Adin, was established March 13, 1904 and discontinued 

December 31, 1905. During the first summer the closing of waste 

gates in the dam at Adin above the gage interferred with the discharge to such an extent that on August 15, 1904, the gage was moved 

to a point 100 feet below the wagon bridge in the town of Adin, which 

was about 500 feet below the dam.

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

the stream and was read daily. Discharge measurements are made 

from a suspension footbridge. The channel is straight for 200 feet 

above and below the gage. The left bank is high but the right bank 

is subject to overflow from a side channel, which in flood diverts 

water from above. The bed of the stream is gravelly and not subject to change.

Discharge measurements of Ash Creek at Adin, Cal., in 1904-5.

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

This station, which is located at Hawkins ranch, in sec. 5, T. 

33 N., R. 5 E., 6 miles above the town of Hat Creek, was established August 15, 1911.

The irrigation canal, which heads about half a mile above the 

gage and diverts about 40 second-feet of water at irregular intervals, 

is the only important diversion for irrigation above the station.

The vertical staff gage is attached to the right support of the 

footbridge near the ranch house.

The channel is fairly smooth and probably permanent.

Discharge measurements are made from the downstream side of 

the bridge.

NOTE. Daily discharge determined from a fairly well defined rating curve; discharge Nov. 26 to 29,, 

Dec. 1, 2, 7, and 9 to 19,1910, estimated from records of discharge of Pit River near Ydalpom, and precipitation records.

For days on which gage was not read during April and May, 1911, the discharge was determined from 

hydrographic comparison with McCloud River at Baird. Daily discharge interpolated for other days 

on which gage was not read.

Estimates of daily discharge for days on which gage was not read are roughly approximate and should 

be used with caution.

MONTGOMERY CREEK AT MONTGOMERY CREEK, CAL.

This station, which is located just below the highway bridge in 

sec. 36, T. 35 N., R. 1 W., at Montgomery Creek post office and 2 

miles above its junction with Sacramento River, was established 

August 11, 1911.

About 5 miles above the station water is diverted from this creek 

to Little Cow Creek by the Terry Lumber Co. During the logging 

season June to December the quantity diverted is 8 to 10 second-feet; for the remainder of the year the amount is reduced to 

about 6 second-feet.

The gage is a vertical staff attached to a large alder tree on the left 

bank 70 feet below the bridge.

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

rough.

Discharge measurements are made by wading or from upstream 

side of highway bridge.

SQUAW CREEK NEAR YDALPOM, CAL.

This station, which is located at the highway bridge three-fourths 

of a mile southwest of Ydalpom (Copper City), in sec. 29, T. 34 N., 

R. 3 W., was established October 4, 1911.

The gage is a vertical staff on the upstream end of the right pier 

of the bridge.

Discharge measurements are made from the bridge or by wading.

The channel, which is composed of gravel and cobblestones, shifts 

slightly at high stages.

One small ditch diverts water for irrigation above the station.

STEEAM MEASUREMENTS IN SACBAMENTO BASIN. 127

M'CLOUD EIVEE NEAE GEEGOEY, CAI,.

This station, which is located at St. John's camp, near Hirze 

Mountain, by road about 14 miles east of Gregory post office, which 

is on. the upper Sacramento, just opposite Baird railroad station, was 

established March 23, 1902, in cooperation with the McCloud River 

Electric Co. The gaging station is 12 or 15 miles above the United 

States fishery at Baird post office, near the mouth of the river. It 

is about one-fourth mile below the mouth of Nosoni Creek. The 

station was discontinued June 30, 1908. Additional gage heights 

were observed from September 12 to 30, 1908, because of extreme 

low-water conditions.

No important tributaries enter below the station, which is only 

about 15 miles above the mouth, and no diversions have been made 

either above or below. Filings on water for power development 

and applications for rights of way over public lands have been made, 

and conflicting rights are still unadjudicated. The flow is not 

affected by artificial conditions above or below the station.

The channel is straight, the banks are high, and the river swift at 

all stages. The bed of the stream is composed of limestone covered 

with large river gravel and bowlders.

The location and the datum of the staff gage remained unchanged. 

Discharge measurements were made from a car and cable. The results at moderate stages are reasonably accurate. No discharge 

measurements were made during 1907 or 1908.

The maximum crest discharge was 55,000 second-feet for a gage 

height of 17.2 feet, February 16,1904. The lowest discharge recorded 

is 1,180 second-feet, September 12 to 16, 1908. No records were 

kept during the early part of the month, but it is probable that this 

stage lasted at least 10 days.

This station, which is,located at the United States fishery at 

Baird, in the NW. i sec. 23, T. 34 N., R. 4 W., about 2,000 feet below 

the mouth of Bailey Creek and about 2,000 feet above the mouth of

bank about 600 feet above the hatchery. The gage records are 

furnished by Capt. G. H. Lambson, superintendent of the fishery.

Discharge measurements are made from a boat about 100 feet 

below the gage until September 27, 1911, when a car and cable were 

installed at the gage.

LITTLE COW CEEEK AT PALO CEDED, CAL.

This station, which is located at the highway bridge in sec. 5, T. 

31 N., R. 3 W., one-fourth mile east of Palo Cedro, was established 

August 9, 1911.

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

and the stream receives water from the Terry Lumber Co.'s flume 

which takes water from Montgomery Creek. From June to December the flume delivers to the creek 8 to 10 second-feet of water; during 

the remainder of the year this quantity is reduced to about 6 secondfeet.

The gage is a vertical staff on the bridge pier near the right bank.

The bed of the stream is composed of gravel and cobblestones and 

the channel may shift slightly at high stages.

Low-water measurements are made by wading; at medium and high 

stages measurements are made from the bridge.

NORTH FORK OF COTTONWOOD CREEK AT ONO, CAL.

This station, which is located at the highway bridge one-fourth mile 

west of Ono in sec. 11, T. 30, N., R. 7 W., was established October 

27, 1907.

The gage is a staff fastened to the middle pier of the bridge near the 

upstream side; its datum has not been changed.

Byron Creek enters just above and Eagle Creek about 1 mile below 

the gage.

The channel is 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 downstream side of the 

bridge at high water and by wading at low water.

The maximum recorded discharge of this creek 4,040 second-feet 

(gage height 9.8 feet) occurred February 2, 1909; the minimum 

flow, / 3 second-feet, occurred during the period August 17, to September 3, 1908.

Several small ditches divert water from the creek above the 

gaging station.

In September, 1908, they carried a total of 14 second-feet. Acquired water rights greatly exceed the low-water flow.
STEEAM MEASUEEMENTS SACEAMEKTO BASIN. 149

The following miscellaneous discharge measurements were made 

of ditches which divert water from North Fork of Cottonwood Creek 

above the gaging station at Ono.

NOTE. Several small canals divert water from Cottonwood Creek above gaging station. Discharge 

measurements made during September, 1908, show a total of 14 second-feet diverted.

MILL CREEK NEAR LOS MOLINQS, 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, 1J 

miles above Los Molinos.

The drainage basin lies east of Sacramento River and between the 

drainage basins of Antelope and Deer creeks.

The gaging station 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.
156 WATEE BESOTJBCES OF CALIFOBNIA PABT I.

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 and bowlders, 

is practically permanent. The current is swift at medium and high 

stages. Both banks arc high and will not overflow:

Discharge measurements are made from the footbridge at the 

gage or by wading.

STONY CREEK NEAR FRUTO, CAL.

This station, which is located at Julian's ranch, about 7 miles northwest of Fruto, and If miles above the Mill Site dam site, in the 

SW. 1 N. E. i sec. 14, T. 21 N., R. 6 W., Mount Diablo base and 

meridian, was established January 30, 1901, to determine the quantity 

of water available for storage at the dam site below.

The only important tributary near the gaging station is Grindstone Creek, which has a drainage area of its square miles and which 

enters from the west 1J miles 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 is in two sections 100 feet above the present cable. The 

high-water portion is a vertical staff. A sloping section, bolted to 

rock, is used for low water. The gage datum has remained unchanged. 

Measurements are made from a car and cable or by wading.

The channel is composed of gravel which shifts more or less during 

the high water, when the current is very swift and the stream is several hundred feet wide. The creek is not liable to overflow until 

the 15-foot stage is reached. Gage heights have been compared 

with the original books and corrected when necessary. The records 

are fair except for very high stages. Estimates for flood flow are 

more or less approximate.

The greatest recorded crest discharge is 36,000 second-feet for a 

gage height of 16.3 feet, 5 p. m., February 2, 1909.

The lowest recorded discharge is 0.5 second-foot, August 21 to 

September 4, 1910.

LITTLE STONY CREEK NEAR LODQGA, CAL.

This station was originally established in March, 1907, by the 

United States Keclamation Service at the East Park dam site, 3J 

miles northeast of Lodoga, in the NW. i NB. i sec. 3, T. 17 N., 

R. 6 W., M. D. B. and M., a short distance below the mouth of Indian 

Creek, about 4 miles above the junction with Stony Creek, to determine the quantity of flood water available for storage in the East 

Park reservoir for use on the Orland project.1

1 For details of investigations made see Cole, Burt, Storage reservoirs oji Stony Creek, California: WaterSupply Paper U. S. Geol. Survey No. 86,1903, also Ninth Ann. Kept. U. g. Reel. Service, 1909-10, pp. 83-89.
176 WATER EESOUECES OF CALIFORNIA PART I.

The construction of the East Park reservoir, which is a concrete 

structure of the gravity type, built on an arch plan, was commenced 

in November, 1908, and was completed in June, 1910. The reservoir 

has a capacity of 46,000 acre-feet. It is planned to irrigate 14,000 

acres of land on both sides of Stony Creek, in the vicinity of Orland.

The gage datum was changed in the fall of 1907, and on June 1,

1909. the gage was moved half a mile downstream to a point a quarter 

of a mile below the reservoir, in sec. 34, T. 18 N., R. 6 W., M. D. B. 

and M., and installed at a different datum. Beginning December 1,

1910. the record is taken from the gage at the reservoir. The records 

at the former locations are only fair, owing to changes in channel.

Discharge measurements were made from a car and cable.

The highest daily discharge is 7,060 second-feet for a mean gage 

height of 11.8 feet, February 2, 1909.

The creek goes practically dry during the summer of low-water 

years.

Records have been furnished by the United States Reclamation 

Service, which maintained the gaging station.

given for estimates after Dec. 1,1910, as the discharge was furnished by the United States Reclamation 

Service.

NORTH FORK OF FEATHER RIVER ABOVE PRATTVILLE, CAL.1

This station which was established June 12, 1905, to determine 

the availability of the North Fork for power development, is located 

3 miles east of Prattville and about 1,300 feet above the junction 

with Hamilton Branch. The drainage area above the station is 245 

square miles. This station was discontinued July 1, 1907.

The channel has a shale bottom subject to slight change. At low 

water it is about 65 feet wide and 5 feet deep; at high water there is 

a diversion overflow around the station, leaving the main stream 

about 1| miles above the point of measurement.

A staff gage was nailed to a willow stump about 15 feet above the 

measuring section. The gage was read daily until October 16, 1905, 

and about once a week after that date.

The greatest discharge during the flood of 1907 is estimated as 

3,900 second-feet, March 19.

The minimum weekly flow of 317 second-feet occurred December 

8 to 14, 1905.

No discharge measurements have been furnished since 1906.
STREAM MEASUREMENTS IN SACRAMENTO BASIN. 183

The following record of gage heights and discharge measurements 

was furnished by Viele, Blackwell & Buck for the Great Western 

Power Co., which maintained the station from the date of its establishment.

Discharge measurements of North Fork of Feather River above Prattville, Cal., in 1905-6.

NOTE. Daily discharge for 1905-1907 was obtained from rating curves applicable as follows: 1905, well 

defined between 325 and 740 second-feet; 1906-7 well defined between 480 and 1,700 second-feet. Discharge 

for days on which gage height was not read interpolated or estimated by aid of a hydrograph comparison 

with the station below Prattville, where daily observations were made most of the time. See note at 

end of monthly discharge table.

NOTE. Computed by the United States Geological Survey from data furnished by the Great Western 

Power Co. The sum of the monthly means for this station and the one on Hamilton Branch has been compared with those for the station below Prattville and the ratios indicate that the values as a whole are good.

NORTH FORK OF FEATHER RIVER BELOW PEATTVILLE, 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 about 5 miles 

southeast of Prattville at J sec. corner on south line of sec. 21, T. 27 

N., R. 8 E., was established by the power company June 13, 1905.

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. The Great Western 

Power Co. probably owns all the water rights above this station.

The bed of the stream is rocky and is unlikely to change materially; 

the current is swift at high stages but moderate at other times. At 

low water the river is about 60 feet wide and its maximum depth is 

9 feet. Thin sheet ice forms occasionally but does not affect the 

relation of gage height to discharge.

Discharge measurements were made from a boat until November 

22, 1905, since which time they have been made from a cabl6 and car.
STBEAM MEASUREMENTS IN SACRAMENTO BASIN. 187

The staff gage is about 700 feet above the cable. The record is kept 

by an automatic gage at the staff gage site; its datum has remained 

unchanged.

The highest recorded daily discharge 9,850 second-feet occurred 

March 19,1907; the lowest flow recorded for any week was 567 secondfeet, December 17 to 23, 1908.

Records at this station are very good.

Power Co. No accuracy is given for 1910, as no base data was furnished to the United States Geologica' 

Survey.

NORTH FOEK OF FEATHEE EIVEE AT BIG BEND, NEAE OEOVILLE, GAL. 1

This station, which was established June 13, 1905, to determine the 

availability of the North Fork for power development, is located 

about 300 feet above the head of Big Bend tunnel at Intake, a station 

on the Western Pacific Railway, and about 15 miles northeast of Oroville, in SE. \ sec. 36, T. 22 N., R. 4 E.

i Formerly known as " near Big Bend."
STREAM MEASUREMENTS IN SACRAMENTO BASIN. 195

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 11 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.

On account of construction work at the station during 1909 no 

gage height record was kept, but estimates of daily discharge for the 

last half of the year have been furnished by the Great Western Power 

Co., which has maintained the station since its establishment.

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.

Discharge measurements are made by means of a boat when the 

stage is below 11.0 feet. For higher stages float measurements are 

made at this point and check measurements are made 2 miles down 

stream from the cable of the Golden State Power Co.

The highest recorded flood occurred at 1 a. m., March 19, 1907, 

when at a gage height of 36 feet the discharge is estimated at 

118,000 second-feet. The lowest weekly flow was 971 second-feet, 

September 10 to September 16, 1908.

Accuracy.

NOTE. Accuracy values for 1909 and 1910 are not published, as the data on which these estimates were 

based was not furnished the United States Geological Survey.

FEATHER RIVER AT OROVILLE, CAL.

This station, which is located about 6 miles below the junction of 

North and Middle forks and about 30 miles above the mouth of 

Yuba River, which enters at Marysville, was originally- established 

January 1, 1902, at the Oroville highway bridge, to obtain data for 

use in studies of flood and reclamation problems in Sacramento 

Valley. No other important tributaries enter near the station.

No diversions are made immediately above the station. All 

acquired water rights are probably for power development.

The United States Weather Bureau gage, located at the bridge, 

was read from 1902 to 1905. All gage heights for those years published herewith refer to a datum 2.0 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 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, 1906; 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
STEEAM MEASUBEMENTS IK SACBAMENTO BASIN. 203

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.

A new staff gage, referred to the old datum, was put in on April 8, 

1907,1,000. feet above the highway bridge and read until Decmber 31, 

1910. 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.

Beginning January 1, 1911 the United States weather gage has 

been used, the station at the cable having been discontinued.

It was hoped that when the station on the Feather River was 

established at the new location above the Oroville Bridge that a 

fairly permanent section was found, but measurements made duringthe past three 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 flood of March, 1907, 

brought down an immense amount of heavy debris and deposited it 

at a point about a quarter of a mile below the gaging section. This 

resulted in much higher gage heights during the following months 

for the same discharge than during the previous year. This debris 

deposit gradually moved out and the relation of gage height to discharge at the gage section began to assume conditions which existed 

prior to the March, 1907, flood. The construction of the Western 

Pacific Railway through the, canyon of the Feather River resulted 

in the wasting of large amounts of heavy debris into the river channel. 

Undoubtedly this d6bris is constantly being brought down the river 

during periods of flood discharge.

Conditions at this station differ from those on the Yuba River 

station. The channel at this station is fairly permanent except 

during flood stages, whereas that of Yuba River is constantly deepening, and the records show increase in discharge with the same gage 

height.

At low water the stream is about 280 feet wide and from 15 to 20 

feet deep, and the current is sluggish.

There are many uncertainties in the records on account of the 

washing out of gages, unreliable observers, and shifting channel 

conditions. The record is also more or less affected by power regulation above the station. Periods of unreliable record, as nearly as 

can be determined, are covered by suitable footnotes in the following 

tables.

The maximum recorded stage is a reading of 30.2 feet at the bridge 

gage, March 19, 1907. This corresponds to a reading of 39.3 feet on 

the gage at the cable and to a discharge of 187,000 second-feet. 

The maximum stage at the cable was estimated from high-water 

mark as 38.5 feet, giving 182,000 second-feet. The lowest recorded 

discharge is 940 second-feet, which occurred October 25, 1910.

» Gage heights for Jan. 1, Jan. 4 to Feb. 4,1902j are unreliable. The river stage was probably below the 

zero of the Weather Bureau gage. (See description.) The observer recorded gage heights to the nearest 

half foot until Mar. 1,1902. Gage heights Jan. 1 to Mar. 1 have since been adjusted, but the revised values 

are only approximate.

t> Gage washed out Apr. 14,1903, New gage set May 7,1903, at presumably the same datum

a Gage heights for 1906 refer to datum of cable gage. See description.

6 The gage was washed out Mar. 19,1907, and a new gage installed at same datum Apr. 8,1907. Gage 

heights observed on the Geological Survey gage for 1907 were evidently in error. Gage heights for these 

periods have been estimated from the Weather Bureau gage on Oroville bridge. The maximum stage 

at the cable was estimated from high-water marks at 38.5 feet; this is somewhat uncertain and the value 

of 39.3 feet obtained from the bridge reading is used.

NOTE. During the summer of 1903 the gage was washed out and later replaced at presumably the same 

datum. The low-water measurement made Nov. 3,1903, plots small of the revised curve. It is questionable whether the gage heights of this measurement is in error or not. Computations have been made on 

the basis of the revised curve, as it fits better the low-water measurements made in 1902 and after 1903. 

Monthly estimates for April, 1903, to about January, 1904, are liable to be too large. Possibly those given 

in Water-Supply Paper 100, p. 274, are better for this period.
STEEAM MEASTJBEMENTS IN SACEAMENTO BASIN. 219

HAMILTON BEANCH OF FEATHEE EIVEE NEAE PRATTVILLE, OAL.

TMs station, which was established June 12, 1905, to obtain data 

for studies of poVer available on North Fork of Feather River, is 

about 3 miles east of Prattville and 1£ miles above the junction with 

North Fork. The drainage area above the station is 230 square 

miles. This station was discontinued July 1, 1907.

The channel is straight and has a shale bottom subject to slight 

change.

Discharge measurements are made from a boat. The datum of 

the staff gage remained unchanged.

The highest daily discharge is estimated from the records below 

Prattville as 4.100 second-feet, March 19, 1907. The lowest weekly 

flow recorded was 168 second-feet in December, 1905, and January 1 

to 7, 1906, but the stage was probably lower in 1908.

The following records of discharge measurements and gage heights 

were furnished by Viele, Blackwell & Buck for the Great Western 

Power Co., which maintained the station since its establishment.

STREAM MEASUREMENTS IN SACRAMENTO BASIN. 223

BUTT CREEK AT BUTTE 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. Its datum has remained unchanged.

No discharge measurements were furnished since 1908.

Records are good, as the changes in channel conditions have been 

well covered by measurements.

The highest recorded daily discharge is 1,640 second-feet, January 

16, 1909. The lowest recorded discharge for one week is 21.3 secondfeet, August 2 to 8, 1908.

The following .data have been furnished by Viele, Blackwell & 

Buck for the Great Western Power Co., which has maintained the 

station since its establishment.

INDIAN CREEK NEAR CRESCENT MILLS, CAL.

This station, which is located about 1 \ miles below Crescent Mills, 

on the Greenville-Taylorsville road and about 2,000 feet below the 

Arlington bridge, in the SW. \ sec. 25, T. 26 N., R. 9 E., was established December 14, 1905, discontinued December 31, 1909, and 

reestablished September 10, 1911.

The station is at the lower end of Indian Valley, above which point 

nearly all the important tributaries enter. Spanish Creek joins In-
STEEAM MEASUREMENTS IN SACKAMENTO BASIN. 231

dian Creek about 4 miles below the station. Water is diverted for 

irrigation above the station.

The bed of the stream is practically permanent at low stages. 

The creek is deep and the current is very sluggish.

The gage is a vertical staff; its datum has remained unchanged.

At high stages discharge measurements were made from a cable and 

car about 20 feet below the gage. The cable was washed out in the 

flood of March, 1907. Since that time measurements are made from 

the bridge above the gage. Low-stage measurements are made by 

wading.

No discharge measurements were made at this station from September 9, 1906, to September 10, 1911. The station was not visited 

during this time, and the accuracy of the determinations of daily 

and monthly discharge from 1907 to 1909 is dependent on the permanency of conditions of flow and the constancy of the elevation 

of the gage.

The river was over the top of the gage March 18, 1907, 6.30 a. m. 

The highest recorded crest gage height is 20.2 feet, 6.30 a. m., March 

19, 1907; estimated discharge, 11,700 second-feet. The river was 

again over the top of the gage January 16, 1909. During the day 

the water had subsided and the observer recorded a gage height of 17 

feet. It is not known which of the two crests was the higher.

The lowest weekly discharge of 12 second-feet occurred August 9 

to 15, 1908. .

NOTE. No discharge measurements have been made from 1906 to 1911, and the estimates for accuracy 

for 1907,1908, and 1909 are dependent on the permanency of conditions of flow and the constancy of the elevation of the gage. Estimates for 1912 are withheld until further discharge measurements can be obtained.

SPANISH CREEK AT KEDDIE, CAL.

This station, which is located at the highway bridge at Keddie, in 

the SW. 1 sec. 22, T. 25 N., R. 9 E., was established October 22, 1911.

The main gage is painted on the left abutment of the bridge. A 

vertical low-water section is fastened to a stump on the left bank 20 

feet below the bridge.

Discharge measurements are made from the downstream side of 

the bridge or by wading.

Water is diverted above the station to irrigate the American Valley.

GRIZZLY CREEK NEAR BECKWITH, CAL.

Grizzly Creek is tributary to the Middle Fork of Feather Elver, 

which enters Feather Kiver above Thermalito, Cal.

The station, which was located at Reno Camp, about 4 miles west 

of Beckwith and 1 mile above Willow Glen Hotel, was established 

December 17,1905, and discontinued on account of lack of an observer 

September 30, 1906. It was maintained to determine the amount of 

water available for storage in the Grizzly Valley reservoir, a short 

distance above, under investigation by the United States Reclamation Service.
244 WATEK EESOTJKCES OF CALIFORNIA PABT I.

The staff gage was nailed to a large cottonwood tree about 800 feet, 

above cable.

Discharge measurements were made from a car on a cable or by 

wading.

The current is rather sluggish at low water but swift at high stages. 

The right bank is high and rocky, the left bank is low and overgrowr 

with cottonwoods near the water's edge, and may be overflowed at 

high water. The bed of the stream is rocky and not subject to 

material change.

The results are only fairly reliable.

Discharge measurements are made from the bridge or by wading.

The channel is composed of gravel and small bowlders.

The diversion dam of the Palermo Land & Water Co.'s canal is 

located 1 mile above the station. The discharge of the canal must 

be added to that of this station to obtain the total run-off from this

MIDDLE FORK OF YTJBA RIVEE AT fBEEMAIF's HBIDGE, NEAR NORTH

SAN JUAN-, CAL. 1

This station was established July 3, 1900

about 1J miles northeast of North San 

.with the California Water and Forest Association

Juan

at Freeman's bridge, 

< Cal., in cooperation 

for the purpose

This stream is locally known as Middle Yuba River.
250 WATEE RESOUECES OF CALIFORNIA PAET I.

of ascertaining the low-water flow during the midsummer season. 

This information was used in a reconnaissance of Yuba River and its 

tributaries. 1 The station was discontinued October 13, 1900. It 

was located a half mile below Oregon Creek and about three-fourths 

of a mile above Moonshine Creek, both of which enter the river from 

the north. It was about 4 miles above the junction with the North 

Fork.

There were no reservoirs storing water on the Middle Fork in 

1900. The only site of any importance is that of the Renyard or 

English reservoir, which has not been in use since the failure of the 

dam in June, 1883. The drainage area of the Middle Fork above 

the mouth of North Fork is 218 square miles.

The channel is composed of sand and gravel recently built up by 

debris from the mines above and is subject to change during floods. 

The precipitation during the wet season preceding the gagings was 

about two-thirds to three-fourths the mean annual rainfall; that 

during the two preceding wet seasons was still further below the 

normal. The records show, therefore, the low-water flow on this 

stream during a period of abnormally low rainfall.

The staff gage which is at the cable is made in two sections and 

Is read daily. The low-water portion is bolted to a rock wall on 

the left bank; the high-water portion is bolted to the wall on the 

right bank. (See PL VIII.) During recent years the bed of the 

stream has been lowering and on August 1, 1906, the gage datum 

was lowered 10.00 feet.

The maximum recorded daily discharge is 111,000 second-feet, for

YUBA RIVER AT PARKS BAR BRIDGE, NEAR SMARTSVILLE, CAL.

This station was established June 28, 1900, at Parks Bar Bridge, 

2 miles northwest of Smartsville, Cal., in cooperation with the 

California Water and Forest Association, to obtain data for a 

reconnaissance of Yuba River and its tributaries.1 It was discontinued October 14, 1900. The river at this point emerges from the 

confines of the steep valley above and spreads out below the station 

into numerous wide, shifting channels and sloughs that meander 

through the broad and gently sloping ranch lands to join the Feather 

Eiver at Marysville. The channel at the bridge has been filled with

sand, gravel, and d6bris brought down from hydraulic mining camps 

in the mountains above, and shifts during high stages.

The data on t*he stream flow in this vicinity have been collected 

from 1903 to 1912 at the Narrows station, about 3 miles above Parks 

Bar Bridge.

OREGON CREEK NEAR NORTH SAN JUAN, CAL.

This station, which is located 150 feet below the highway bridge, 

one-half mile above Freeman's Crossing, 2 miles northeast of North San 

Juan, in the N. £ SE. \ sec. 28, T. 18 N., R. 8 E., in the Tahoe National 

Forest, was established October 28, 1910.

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

150 feet below the bridge and about 500 feet above the mouth of the 

stream.

A car and cable were installed on November 8, 1911, 30 feet below 

the gage, as the section at the bridge is very rough. Low-water 

measurements are made by wading.

Discharge estimates are withheld until high-water measurements 

are secured at the cable section.

i Known locally as North Yuba River
272 WATER EESOTJECES OF CALIFORNIA PART I.

NORTH; FORK OF TUBA RIVER 1 AT GOODYEAR BAR, CAL.

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

Bar, in the E. £ SW. i sec. 5, T. 19 N., R. 10 E., was established 

October 31, 1910.

The first important tributary above the station is the North Fork 

of the North Fork, 4 miles upstream. Rock Creek enters about oneeighth mile and Goodyear Creek about one-fourth mile below the 

station.

In the early days Goodyear Bar and Downieville were large placerminirig 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 upper section 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.

NOETH rORK OF YUBA EIVEE NEAE NOETH SAN JUAN, CAL.

This station was established July 3, 1900, above the Yuba Power 

Co.'s dam, about 1| miles above the confluence of North Fork and 

Middle Fork and about 2 miles northwest of North San Juan, Cal., in 

cooperation with the California Water and Forest Association, for the 

purpose of obtaining the low-water flow during the midsummer season. 

The data were used in a reconnaissance of the power possibilities of 

the Yuba and its tributaries.1 It is below all large tributaries. The 

river at this point runs in a deep, wide canyon, whose channel is 

irregular, composed of gravel, sand, and clay, and which is subject 

to change during floods. The drainage area of the North Fork at its 

mouth is 492 square miles.

The precipitation during the wet season preceding the gagings 

was about two-thirds to three-fourths of the mean annual rainfall. 

Precipitation during the two preceding wet seasons was still further 

below the normal. The records show, therefore, the low-water 

flow on this stream during the period of abnormally low rainfall.

NORTH FORK OF NORTH FORK OF YUBA RIVER AT DOWNIEVILLE, CAL. 1

This station, which is located in the NE. J NW. J sec. 35, T. 20 N., 

R. 10 E., in the Tahoe National Forest, at upper highway bridge in 

Downieville, 500 feet above the dam and one-fourth mile above the 

mouth of the river, was established November 1, 1910.

The principal tributaries of this stream are Rattlesnake Creek, 

Middle Fork, and East Fork, all of which enter above the station.

A small ditch, which furnishes water for domestic uses at Downieville, heads above the station.

The gage is a vertical staff fastened to the left face of the right 

pier of the highway bridge.

Discharge measurements are made from this bridge and also from 

the bridge near the mouth.

The gage-height record is furnished by John T. Mason.

MEASUREMENTS IN SACRAMENTO BASIN.

ROCK CREEK AT GOODYEAR BAR, CAL.

This station, which is located near the footbridge at Goodyear 

Bar 600 feet above its junction with North Fork of Yuba River, in 

the W. i SW. | sec. 5, T. 19 N., R. 10 E., in the Tahoe National Forest, 

was established October 30, 1910.

The principal tributary is Woodruff Creek, which enters 350 feet 

above the station and about 600 feet above the mouth.

Three small ditches, having a total capacity of about 10 secondfeet, head above the station. Two of these, Paul BachePs ditch and 

Williams' ditch, divert water from Woodruff Creek about one-fourth 

mile above its junction with Rock Creek. The intake of the Kennedy 

ditch is about three-fourths mile above the mouth of Rock Creek. 

Paul Bachel's ditch, which supplies water for domestic use in the 

town of Goodyear Bar, carried 0.69 second-foot on October 31 and 

0.96 second-foot on December 8, 1910.

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

Discharge measurements are made from the bridge 40 feet above 

the gage or by wading.

This station is maintained in cooperation with the United States 

Forest Service.

GOODYEAR CREEK AT GOODYEAR BAR, CAL.

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

north of Goodyear Bar in the W. \ SW. J sec. 5, T. 19 N. ; E. 10 E., 

in the Tahoe National Forest, was established 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 

1\ 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 Moran-Casserly ditch takes water 

from Eureka Creek, 3J miles above its mouth, and the Casserly ditch 

from Collins Ravine, 2 J miles above its mouth.

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

Discharge measurements are made from the bridge, 200 feet below 

the gage or by wading.

This station is maintained in cooperation with the United States 

Forest Service.

BEAE EIVEE NEAE COLFAX, CAL.

This station, which is located at the Pacific Gas & Electric Co.'s 

dam, half a mile below the mouth of Greenhorn River, in sec. 22, T. 

15 N., R. 9 E., and about 3 miles north of Colfax, was established 

August 14, 1911.

Three gages at different locations and datums have been used. 

The first was a vertical staff installed at a highway bridge below the 

dam. This gage was read from August 14 to October 31, 1911. On 

October 20, 1911, a second gage was installed about 500 feet above 

the dam and read from November 1 to December 31, 1911. A third 

gage in three sections was installed December 9, 1911, on the left 

bank about 50 feet above the dam. This gage was read beginning 

January 1, 1912. The heights observed at the first gage were taken 

once daily and are not a true index of the 24-hour discharge, owing to 

regulation at the dam and at storage reservoirs above the station. 

Because of their unreliability these heights are not published. The 

second gage was above the backwater influence of the dam, but 

records at this point were affected by shifting channel conditions. 

The third gage is within the influence of the dam, which serves as a 

control for the gage heights. The crest of the dam is at an elevation 

of 5.21 feet on this gage.

Discharge measurements have been made by wading either above 

or below the dam, or from a cable, installed December 9, 1911, at the 

site of the second gage.

The channel at the bridge below the dam is composed of large 

bowlders and gravel. The channel above the dam is largely filled in 

with tailings from hydraulic mining and is quite shifting.
288 WATER RESOURCES OF CALIFORNIA PART I.

The Pacific Gas & Electric Co.'s power canal diverts water at the 

dam. The company has obtained records of the flow in the canal, 

the gage and gaging section being located in a flume about 750 feet 

below the headgate.

The flow at the station will have to be considered in two parts 

the flow over the dam and the flow in the power canal. Sufficient 

data and information to make reliable estimates are not yet available. 

Only river gage heights and discharge measurements of canal and 

river are published herewith.

Water is diverted into this drainage from South Fork of Yuba River - 

Storage has also been developed on the headwaters of this stream.

The station is maintained in cooperation with the Pacific Gas & 

Electric Co.

BEAR RIVER AT VAN TRENT/ CAL.

This station, which is located about 500 feet below the highway 

bridge at McCourtney crossing 1 mile below Van Trent post office, 

and 8 miles above Wheatland, was established October 8, 1904, in 

the SE. | sec. 2 , T. 14 N., R. 6 E.

No important tributaries enter near the station. Wolf Creek, 

tributary from the north about 30 miles above, drains an area comprising 76 square miles. Rock Creek, a very small stream, enters

1 Referred to in earlier water-supply pipers as " above Wheatland." Van Trent is a new post office.

about three-quarters of a mile below. No diversions are made immediately above the station.

The gage is a staff in five sections on the left bank below the bridge; 

its datum has remained unchanged.

The bed of the stream is solid rock, bowlders, and gravel, and the 

current is swift at all stages.

Discharge measurements have been made from a cable and car 300 

feet below the gage, except at low water, when they are made by 

wading. The cable equipment was removed in November, 1909. 

High-water measurements may be made from the bridge. The station 

is inaccessible at extreme high stages. Only float velocities can be 

taken in flood.

There are diversions above the station for power and irrigation. 

Storage is also developed in the headwaters of the stream.

The maximum gage height recorded is 18.9 feet at 8 a. m. January 

14, 1909; crest discharge, 29,600 second-feet. A crest discharge of 

28,200 second-feet for crest stage of 18.5 feet occurred February 2, 

1907. 'i'he minimum recorded weekly flow was 10 second-feet, 

November 13 to 19, 1905.

In general, conditions for determining discharge are poor, because 

of the rough channel and torrential nature of the stream.

AMERICAN RIVER AT FAIROAK$, (<3AL.

This station, which is located at the Fairoaks highway bridge 

about 1,500 feet north of the railroad station,'was established November 3, 1904, to obtain data for use in connection with studies of flood 

problems in the Sacramento Valley. The old bridge was destroyed
STEEAM MEASUREMENTS IN SACRAMENTO BASIN. 303

by flood March 19, 1907, after which time measurements were made 

from a temporary bridge until the end of 1908. This temporary 

bridge washed out January 13, 1909. A new steel bridge was completed early in 1909 and measurements are now made from it except 

at extreme low water, when wading measurements can be made.

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.

Some water is diverted for power and for irrigation at points above 

the station, but the quantity is not known. Water is also stored.

The present gage is located at the bridge section. A low-water 

staff gage is fastened to a pile 10 feet below the concrete pier on the 

right bank. This gage is graduated from 0 fo 6 feet. The concrete pier on the left bank is graduated from 5 to 40 feet. The 

gage is read twice daily. The position of the gage has been changed 

several times during the life of the station, but no change has been 

made in the datum.

The conditions for obtaining accurate discharge data are poor. 

The stream is torrential and has a changeable bed; the current is 

sluggish at low, and very swift at moderate, stages; the flow is disturbed by bars at low water and by concrete piers at other stages, 

and the channel conditions near the right bank are disturbed by a 

large eddy, which is very objectionable at all stages except the lowest.

The maximum crest discharge of 119,000 second-feet with a gage 

height of 30.4 feet occurred March 19, 1907. The lowest discharge is 

uncertain. Some extremely, low stages reported for the last part of 

December, 1908, have been discarded, and it is believed that the 

mean of 104 second-feet for the week of November 14 to 20, 1908, 

represents minimum conditions.

NOTE. Mean discharge October, November, and December, 1911, is the combined discharge (preliminary estimates) of North Fork of American River near Colfax, Middle Fork of American River near East 

Auburn, and South Fork of American River near Placerville, plus an assumed inflow of from 20 to 30 second1661.

MIDDLE FORK OF AMERICAN RIVER NEAR EAST AUBURN, CAL.

This station, which is located at the Mountain Quarry Co.'s plant, 

about 1^ miles above the junction with North Fork of American 

River and 3^ miles northeast of Auburn, was established October 22, 

1911.

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

pump house.

Discharge measurements are made by wading or from a car and 

cable 300 feet below the gage*.

The channel is composed of gravel and small bowlders and will 

shift at high stages.

RUBICON RIVER AT RUBICON SPRINGS, CAL.

This station is located in the SE. J sec. 31, T. 14 N., R. 16 E., at 

Rubicon Springs, about three-fourths of a mile above mouth of Miller 

Creek.

A staff gage is used. Discharge measurements are made from car 

and cable.

The channeUs composed of sand and gravel and is fairly permanent.

The drainage area above the station is 31.6 square miles.

During the winter the determination of discharge is rendered somewhat uncertain by the presence of ice. Results for the remainder 

of the year are excellent.

The following record was furnished by the Stone & Webster Engineering Corporation:

Daily discharge, in second-feet, of Rubicon River at Rubicon Springs, Cal., for 1910-11.

LITTLE SOUTH FORK DITCH AT SAWMILL NEAR QUINTETTE, CAL.

This station is located at the flume across Little South Fork of 

Kubicon River about half a mile above sawmill, and 15 miles northeast of Quintette.

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

mouth. The course of the ditch is south until it crosses the Little 

South Rubicon; it then follows down the valley to a point in the main 

Rubicon Canyon, where a tunnel carries it into the Pilot Creek 

drainage area a total distance of about 10 miles.

The following record was furnished by the Stone & Webster Engineering Corporation:

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

for 1910-11.

PILOT CREEK NEAR QUINTETTE, CAL.

This station is located at the Bacchi road crossing in the NW. i 

NW. | sec. 10, T. 12 N., R. 12 E., about three-fourths of a mile 

southwest of Bacchi and 4 miles east of Quintette.

A staff gage is used and discharge measurements are made from 

car and cable. The drainage area above the station is 18.7 square 

miles.

The flow of Pilot Creek ditch must be added to determine total 

run-off from the drainage area. The natural run-off from the Pilot 

Creek basin is increased by water diverted from Gerle Creek.

The channel is compact gravel and results are excellent.

Engineering Corporation:

STREAM MEASUREMENTS IN SACBAMENTO BASIN.

SOUTH FORK OF AMERICAN RIVER AT KYBURZ, CAL.

333

This station was located at Nielson's ranch (Kyburz post office), 

in the NE. \ sec. 28, T. 11 N., R. 15 E., half a mile above the junction with Silver Fork and half a mile below Slippery Ford.

The gage was a vertical staff on the right bank. Discharge measurements were made from a car and cable at the gage. Flow was 

practically controlled by storage at Echo Lake. The channel is 

composed of sand and gravel and fairly smooth. Results are good.

The following record was furnished by Duryea, Haehl & Oilman, 

of San Francisco, Cal.

SOUTH FORK OF AMERICAN RIVER NEAR KYBURZ, CAL.

This station was located about half a mile below the intake of the 

Eldorado canal and the mouth of Silver Fork, and 1 mile below 

Kyburz post office.

A recording gage was installed on the left bank and discharge 

measurements made from a car and cable.

The flow was partly regulated by storage at Echo and Silver 

lakes. The Eldorado canal, which supplies water for irrigation .and 

mining, carried about 60 second-feet during the irrigation season 

(June 15 to September 30) and about 30 second-feet during the 

remainder of the year. Results are good.

CLEAR LAKE IN LAKE COUNTY, CAL.

In 1889 the United States Geological Survey made a topographic 

survey of Clear Lake and its qutlet. A datum plane was taken 1.27 

feet above the low-water mark of 1873 and called 100. *Mr. Win. 

Ham. Hall compiled a number of tables for his report on this survey; 

one of which is given herewith.

In the following table is given the mean monthly and annual level 

of the surface of Clear Lake. The records up to 1888 were given to
STEEAM MEASTJEEMENTS IN SACEAMENTO BASIN. 339

Mr. Hall by Capt. Floyd, of Kono Tayee. The later records were 

obtained in 1900 from Mr. F. H. Porter, of Kono Tayee, and from 

Capt. Rumsey and Capt. Atherton, of Lakeport.

340 WATER RESOURCES OF CALIFORNIA PART I.

CACHE CEEEK AT LOWEE LAKE, CAL.

This station was established January 1, 1901, to determine the 

outflow 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 Seigler Creek. On 

March 26, 1903, a cable was installed 300 feet above the bridge and 

above Seigler Creek, and a new staff gage was iset 100 feet above the 

cable on the left bank. On March 26, 1903, 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. Seigler 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. Th.e stream bed at this 

point forms a gravel bar which controls the outlet of Clear Lake. 

The grade of the creek down to Seigler Creek is small. When Cache 

Creek is low and Seigler Creek high, the current of Cache Creek 

may be reversed, and part of the water from Seigler Creek finds its 

way up stream into Clear Lake, the rest flowing down stream into 

Cache Creek. This phenomenon happens at extreme flood stages 

and causes backwater at the gage above the cable. The flow from 

Seigler Creek is very small, except at these flood periods, which are 

usually of short duration.

The reading of the gage is believed to be at all times an index of the 

discharges below Seigler Creek.

In computing the revised estimates, measurement showing reduced 

discharges have been discarded. The values as given are therefore 

directly comparable with those obtained at the original location of 

the station at the bridge. v

The channel is subject to only slight changes. The station is well 

rated and results as a rule are excellent.

The maximum recorded gage height of 13.8 feet, crest discharge 

of 4,340 second-feet occurred February 20, 1909.

The lowest weekly flow is 3.71 second-feet, November 21 to November 27, 1910.

356 WATER RESOURCES OF CALIFORNIA PART I.

CACHE CREEK AT YOLO, CAL.

This station was established January 1, 1903, at the old wagon 

bridge on the road from Woodland to Yolo, about 1,000 feet above 

the railroad bridge, for the purpose of obtaining general statistical 

and comparative data regarding the flow of Cache Creek. The data 

are useful in connection with power and irrigation development and 

in studies of flood prevention in Sacramento Valley. In the fall of 

1904 a new bridge was constructed, and the gage record interrupted 

from September 11 to October 1, 1904.

No important tributaries enter within 12 or 15 miles of the station.

Many diversions are made from Cache Creek above the station, 

water being used for 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 up-stream side of the right 

abutment of the old wagon bridge and read twice each day. On 

October 2, 1904, .a new gage was installed. The gage at the new 

location 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 remained the same as before and has been 

unchanged during the life of the station. Discharge measurements 

have been made from the down stream side of the bridge.

A landslide occurred in Cache Creek .canyon above the station, on 

May 2, 1906, damming the flow. This dam was overtopped on May 

7, when the creek rose to the maximum gage height of 20.8 feet.

The records are good, considered as a whole. The bed of the stream 

is composed of earth 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 maximun crest 

discharge was 20,800 second-feet for a gage height of 27.8 feet, 

February 3, 1909. The creek is dry at the station almost every 

summer or fall.

a A landslide occurred in Cache Creek canyon, above the station, on May 2,1906, damming the flow. 

This dam was overtopped on May 7, when the creek rose to a maximum gage height of 20.8 feet. The 

measurements of this date were made at the crest of the flood.

6 The measurement on Mar. 21,1907, was made just after the big flood and was possibly affected by

PUTAH CREEK NEAR GUENOC, CAL.

This station was established February 12, 1904, at the Guenoc 

dam site, about 2 miles below the old town of Guenoc, near the Asbill 

ranch house, to determine the amount of water available for storage 

in the proposed reservoir near Guenoc. The nearest post office is 

in Middletown, Cal.. The station was discontinued July 31, 1906.

The gaging section was located in a narrow gorge at the lower end 

of a long, flat valley, which is flooded during high water. The channel 

will not allow the water to run off through the gorge fast enough 

49685° WSP 298 12 :24
370 WATEB BESOUKCES OF CALIFORNIA PART I.

to prevent backwater forming during flood periods. The bed of the 

stream is gravelly with a few bowlders above and below the section. 

Bed rock is laid bare on the right side of .the channel. The banks 

are not liable to overflow, but at extreme high water the right bank 

broadens out into a wide bench, increasing the section considerably. 

Meter measurements during high water are made from a car and 

cable. The cable was located directly opposite the ranch house at 

first, but on November 15, 1904, it was moved to a more favorable 

location, about 1,000 feet below. During low water measurements 

were made by wading. The gage established near the old section 

was read once a day during ordinary stages and twice a day during 

high water. It is a vertical staff in two sections. The low-water 

section was about 600 feet up stream from the high-water section. 

An auxiliary staff gage' was installed near the new cable location. 

The gage datum has remained unchanged.

The highest crest discharge recorded is 24,600 second-feet for a 

gage height of 20.1 feet, 11 a. m., March 10, 1904. The creek reached 

a minimum of 4 second-feet August 14 to 19, 1905.

PUTAH CREEK AT WINTERS, CAL.

This station, which is located 600 feet below the Southern 

Pacific Co.'s bridge at Winters, was established September 26, 1905, 

to determine the amount of water available for storage in the proposed reservoir near Winters. The data are very valuable for irrigation and power projects and for use in connection with any plan for 

flood prevention in the Sacramento Valley.

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 channelis straight, and the main portion is clear for the most part. 

At very high flood 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.

The records are good except at very low stages, when, owing to the 

width of channel and its tendency to shift somewhat, gage heights 

are not a reliable index of the flow.

The staff gage was originally installed on the south (right) channel. 

On August 15, 1906, a new staff gage, in five sections,* was installed in 

the north (left) channel at the same datum. Owing to sand bars at 

the station, the elevation of the water levels in the two channels did 

not read the same. Most of the water at medium and low water flows 

in the south (right) channel. All gage heights prior to 1911 have been
STREAM MEASUREMENTS IN SACRAMENTO BASIN. 375

adjusted to refer to the gage in the north (left) channel for which the 

rating curve applies. Beginning January 1, 1911, each channel has 

been rated separately. (See footnotes to gage heights.)

In the summer of 1911 and also in 1912 a temporary dam was built 

across the creek 500 feet below the gages. The pond created was used 

for recreation and extended from half to three-quarters of a mile upstream. The dams go out at the first high water. The gage heights 

during most of the period, May 17 to October 2, 1911, have been 

omitted, as frequent changes in the dam rendered them useless as an 

index of the discharge. The dam installed May 15, 1912, again 

affected the gage heights and a temporary gage was installed below 

the dam on June 10 for use during the summer.

Discharge measurements are made from a car and cable at the 

regular gage location or by wading at low water.

The maximum recorded crest discharge is 37,000 second-feet for a 

gage height of 29.0 feet, March 23, 1907. The lowest discharge was 

1 second-foot September 10 and 11,.1910.

NOTE. Gage heights Apr. 6 to May 31 and Nov. 22 to Dec. 31, 1909, have been adjusted to refer to the 

normal water level of the permanent gage In the north channel. Gage heights observed on north channel gage Jan. 1 to May 22,1911 (except Mar. 12 and 13, which were the same on both gages), and June 19 

to 24,1911. Gage heights observed on south gage May 23 to June 18 and June 25 to Dec. 31,1911. Gage 

heights about May 17 to Dec. 31.1911, affected by backwater from temporary dam constructed about 500 

feet below the station to form a boating and swimming pond. The gage heights during most of the period 

May 17 to Oct. 2.1911, were between 8 and 10 feet and are omitted, since frequent changes in the dam 

render them useless as an index of the discharge. There was relatively little backwater Oct. 3 to Dec. 

31. 1911. and the relation of gage height to discharge was stable. Gage heights Mar. 5 to 7,1911, determined from hydrograph.

Daily discharge, in second-feet, of Putah Creek at Winters, Cal., for 1905-1912.
