SURFACE WATER SUPPLY OF COLORADO RIVER BASIN,

1910.

By W. B". FREEMAN, E. C. LA RUE, and H. D. PADGETT.

INTRODUCTION.

AUTHORITY FOR INVESTIGATIONS.

This volume contains results of measurements of the flow of certain 

streams in the United States. The work was performed by the 

United States Geological Survey, either independently or in cooperation with private or State organizations. The organic law of the 

Geological Survey (Stat. L., vol. 20, p. 394) contains the following 

paragraph:

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

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

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

the investigation of water resources is authorized under the provision for examining mineral resources. The work has been supported 

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

successive sundry civil bills passed by Congress under the following 

item:

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

for the investigation of underground currents and artesian wells, and for the preparation of reports upon the best methods of utilizing the water resources.

The various appropriations that have been made for this purpose 

are as follows:

Annual appropriations for the fiscal year ending June 30 

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

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

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

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

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

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

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

1911..... - .... ..................... ......................... 150,000

SCOPE OF INVESTIGATIONS.

These investigations are not complete nor are they inclusive of all 

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

work is limited by the appropriations available. The field covered 

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

best possible under the controlling conditions. The work would 

undoubtedly have greater scientific importance and ultimately be of 

more practical value if the money now expended for wide areas were 

concentrated on a few small drainage basins; but such a course is 

impossible because general appropriations made by Congress are 

applicable to all parts of the country. Each part demands its proportionate share of the benefits.

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

period of years long enough to determine within reasonable limits 

the entire range of flow from the absolute maximum to the absolute 

minimum. The length of such a period manifestly differs for different streams. Experience has shown that the records for some 

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

years or even more, the limit being determined by the relative 

importance of the stream and the interdependence of the results 

with other long-time records on adjacent streams.

In the performance of this work an effort is made to reach the 

highest degree of precision possible with a rational expenditure of 

time and a judicious expenditure of a small amount of money. In 

all engineering work there is a point beyond which refinement is 

needless and wasteful, and this statement applies with especial force 

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

stream-flow data presented in the publications of the Survey are in 

general sufficiently accurate for all practical purposes. Many of the 

records are, however, of insufficient length, owing to the unforeseen 

reduction of appropriations and consequent abandonment of stations. 

All persons are cautioned to exercise the greatest care in using such 

incomplete records.

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

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

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

also been investigated. During 1910 regular gaging stations were 

maintained by the Survey and cooperating organizations at about 

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

were made at other points. Data were also obtained in regard to 

precipitation, evaporation, storage reservoirs, river profiles, and water 

power in many sections of the country, and will be made available in 

the regular surface water-supply papers and in special papers from 

time to time.

PUBLICATIONS.

The data on stream flow collected by the United States Geological 

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

changes in governmental requirements the character of the work 

and the territory covered by these different publications have varied 

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

a general plan has been agreed upon by the United States Reclamation 

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

Bureau, and the United States Geological Survey, according to which 

the area of the United States has been divided into twelve parts, 

whose boundaries coincide with certain natural drainage lines. The 

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

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

Atlantic and south Atlantic drainage areas lies between York and 

James rivers.

NOTE. No data regarding stream flow are given in the fifteenth and seventeenth annual reports.

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

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

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

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

the numbers of the papers on surface-water supply published from 

1899 to 1910. Wherever the data for a drainage basin appear in two 

papers the number of one is placed in parentheses and the portion 

of the basin covered by that paper is indicated in the second table. 

For example, in 1904 the data for Missouri River were published in 

Water-Supply Papers 130 and 131, and the portion of the records 

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

table, is that relating to Platte and Kansas rivers.

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

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

having the largest drainage area is considered the continuation of the 

main stream, and local changes in name and lake surface are disregarded. Eecords for all stations from the source to the mouth of the
12 SURFACE WATER SUPPLY, 1910, PART IX.

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

The exceptions to this rule occur in the records for Mississippi 

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

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

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

over the lake surface.

DEFINITION OF TERMS.

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

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

into two groups (1) those which represent a rate of flow, as secondfeet, gallons per minute, miner's inches, and run-off in second-feet per 

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

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

this series of reports are second-feet, 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 rate of discharge of water flowing in a stream 1 foot wide, 1 foot 

deep, at a rate of 1 foot per second. It is generally used as a fundamental unit from which others are computed by the use of the factors 

given in the following table of equivalents.

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

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

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

regards time and area.

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

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.

"Acre-foot" is equivalent to 43,560 cubic feet, and is the quantity 

required to cover an acre to the depth of 1 foot. It is commonly used 

in connection with storage for irrigation work.

EXPLANATION OF DATA.

For each drainage basin there is given a brief general description 

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

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

or important facts.

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

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

measurements, table of daily gage heights, table of daily discharges, 

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

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

In addition to statements regarding the location and installation 

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

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

gage height to discharge, covering such points as ice, logging, shifting 

channels, and backwater; also information regarding diversions 

which decrease the total flow at the measuring section. Statements 

are also made regarding the accuracy and reliability of the data.

The discharge-measurement table gives the result of the discharge 

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

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

discharge in second-feet.

The table of daily gage heights records the daily fluctuations of 

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

taken each day. At most stations the gage is read in the morning 

and in the evening. The gage height given in the table represents 

the elevation of the surface of the water above the zero of the gage. 

All gage heights affected by the presence of ice in the streams or 

by backwater from obstructions are published as recorded, with 

suitable footnotes. The rating table is not applicable for such 

periods unless the proper corrections to the gage heights are known 

and applied. Attention is called to the fact that the zero of the gage 

is placed at an arbitrary datum and has no relation to zero flow or 

the bottom of the river. In general the zero is located somewhat 

below the lowest known flow, so that negative readings shall not 

occur.

The discharge measurements and gage heights are the base data 

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

The rating table gives, either directly or by interpolation, the 

discharge in second-feet corresponding to every stage of the river 

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

heights and daily discharges for the purpose of verifying the published 

results as follows:

COLORADO RIVER BASIN. 15

First plot the discharge measurements for the current and earlier 

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

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

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

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

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

curve used and will lie among the plotted discharge measurements. 

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

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

These values should be so adjusted that the first differences shall 

always be increasing or constant, except for known backwater periods.

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 in page 12, are based.

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

this series of reports are described in the introductory sections of 

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

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

and Plate II shows the various types of current meters * used in the 

work.

ACCURACY AND RELIABILITY OF FIELD DATA AND COMPARATIVE

RESULTS.

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

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

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

degree of permanency of channel and of permanency of the relation 

between discharge and stage.

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

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

errors due to misinterpretation of stage and flow data.

i See Hoyt, J. C., and others, Use and care of current meter as practiced by the United States Geological 

Survey: Trans. Am. Soc. Civil Eng., vol. 66, 1910, p. 70,

16 SUEFACE WATEE SUPPLY, 1910, PAET IX.

Practically all discharge measurements made under fair conditions 

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

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

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

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

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

more reliable than those from stations at dams, where the coefficient 

may be uncertain and conditions of flow are complicated.

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

observers. With relatively few exceptions the observers perform 

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

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

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

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

source are compensating and virtually negligible in a period ofone 

month, although a single day's reading may, when taken by itself, be 

considerably in error.

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

the purpose of making a measurement to determine the constancy 

of conditions of flow since the last measurement made in the preceding 

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

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

current year. If conditions of flow have been reasonably permanent 

up to the time of the last preceding measurement, it is considered 

best to publish estimates of discharge based on the latest verified 

rating curve rather than to omit them altogether, although it should 

be distinctly understood that such records are at times subject to considerable error. This is also true, although to a less degree, of the 

period of records since the date of the last measurement of the current 

year. As a rule, the accuracy notes are based on the assumption that 

the rating curve used is strictly applicable to the current year.

In order to give engineers and others information regarding the 

probable accuracy of the computed results, footnotes are added to 

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

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

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

well denned," within 10 per cent; "poorly denned " 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
COLORADO RIVER BASIN. 17

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.

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

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

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

opportunity of examining the computed results and of changing and 

adjusting them as may seem best to him. Although it is believed 

that the rating tables and computed monthly discharges are as good 

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

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

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

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

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

these papers will verify all ratings and make such adjustments for 

earlier years as may seem necessary. The work of compiling, studying, revising, and republishing data for different drainage basins for 

5 or 10 year periods or more is carried on by the United States Geological Survey so far as the funds for such work are available.

The estimates in the table of monthly discharge are so arranged as 

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

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

estimates.

The daily discharges are published to allow a more detailed study 

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

COOPERATIVE DATA.

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

at many stations maintained wholly by private funds are incorporated 

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

Survey.

Many stations throughout the country are maintained for specific 

purposes by private parties who supply the records gratuitously to 

the United States Geological Survey for publication. When such 

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

values of accuracy are given. Kecords clearly worthless or misleading are not published. As it is, however, impossible to completely 

verify all such records furnished because of lack of funds or for 

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

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

information regarding stream flow at the particular localities. The 

survey does not, however, assume any responsibility for inaccuracies 

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

reasonably good.

GENERAL FEATURES OF COLORADO RIVER BASIN.

Colorado River is formed in the southeastern part of Utah by the 

junction of Grand and Green rivers. The Green is larger than^ the 

Grand and is the upward continuation of the Colorado. Including 

the Green, the Colorado is about 2,000 miles long. The region drained 

is about 800 miles long, ranges in width from 300 to 500 miles, and 

contains about 300,000 square miles. It comprises the southwestern 

part of Wyoming, the western part of Colorado, the eastern half of 

Utah, practically all of Arizona, and small portions of California, 

Nevada, New Mexico, and old Mexico. Most of this area is arid, 

the mean annual rainfall being about 8^ inches. The streams receive 

their supply from the melting snows on the high mountains of Wyoming, Utah, and Colorado.

The basin comprises two distinct portions. The lower third is but 

little above;the, level of the sea, though here and there ranges of mountains rise to elevations of 2,000 to 6,000 feet. This part of the valley 

is bounded on the north by a line of cliffs which present a bold and in 

many places vertical step of hundreds or thousands of feet to the tableland above. The upper two-thirds of the basin stands from 4,000 

to 8,000 feet above sea level and is bordered on the east, west, and 

north by ranges of snow-clad mountains, which attain altitudes ranging from 8,000 to 14,000 feet above sea level. Through this plateau 

the Colorado and its tributaries have cut narrow gorges or canyons 

in which they flow at almost inaccessible depths. At points where 

lateral streams enter, the canyons are broken by narrow transverse 

valleys, diversified by bordering willows, clumps of box elder, and 

small groves of cottonwood. The whole upper basin of the Colorado 

is traversed by a labyrinth of these canyons, most of which are dry 

during the greater portion of the year and carry water only during 

the melting of the snow and the brief periods of the autumnal and 

spring rains.
COLORADO BJVER BASIN. 25 

GREEN RIVER AND THE MAIN COLORADO RIVER. 

GENERAL FEATURES OF ABBA DRAINED.

Green River and its tributaries * drain an area rudely triangular 

in outline, bounded on the north and east by the Wind River Mountains and the ranges forming the Continental Divide, on the south 

.and east by the White River Plateau and the Roan or Book Cliffs, 

and on the north and west by the Gros Ventre and Wyoming mountains and the great Wasatch Range. The greatest length of the 

basin, north and south, is about 370 miles. In an east-west direction it measures at the widest part about 240 miles. The total 

drainage area is approximately 41,000 square miles. Altitudes 

range from 14^000 feet in the high mountains to about 3,800 feet 

at the mouth of the Grand.

The area includes a large part of western Wyoming, northwestern 

Colorado, and eastern Utah. The Uinta and Uncompahgre Indian, 

reservations are located in this basin in northeastern Utah.

Green River heads on the western slope of the Wind River Mountains in western Wyoming, its ultimate source being a number of 

small lakes fed by the glaciers and immense snow deposits always to 

be found on Fremont and neighboring peaks. For perhaps 25 miles 

the river flows northwestward through the mountains; it then turns 

abruptly and runs in a general southerly direction across western 

Wyoming and Utah. A few miles below the Wyoming-Utah boundary another sharp turn carries the river eastward near the east end 

of the range. It then flows southward in Colorado for about 25 

miles, turns back into Utah, and continues to flow in a southwesterly 

and southerly direction until it unites .with the Grand to form the 

Colorado. Its length, measured roughly along the course, is approximately 425 miles.

In its upper course the Green receives as tributaries numerous 

streams heading in the Wind River, Gros Ventre, and Wyoming 

ranges, some1 of them extending so far back into the abrupt, ragged 

canyons that they dovetail with streams flowing in the opposite 

direction. The most important of these tributaries are New Fork 

River, Big Sandy Creek/ Labarge Creek, Fontenelle Creek, Black 

Fork, and Henry Fork. South of the Uinta Mountains the first 

large stream flowing into the Green is the Yampa, which comes in 

from the east at the point where the Green turns westward to reenter 

Utah after its southward journey in Colorado. Farther south Ashley 

Creek and Duchesne and White rivers discharge their waters into 

the Green, Ashley Creek and the Duchesne from the west and the 

White from the east. Below this point the only tributaries of

The geology of this basin is described in the Eleventh Ann. Rept. U. S. Geol. and Geog. Survey Terr., 

for 1877, pp. 509-646. ^Information in regard to the hydrography is contained in the first to fourth annual 

reports of the Reclamation Service and in the United States Geological Survey reports.
26 SURFACE WATER SUPPLY, 1910, PART IX.

importance are Price, Minnie Maud, and San Kafael rivers, which 

enter from the west, the San Kafael at a point about 32 miles above 

the junction of the Green and the Grand.

Over the plains portion of the basin, which includes considerably 

over half of it, the average annual precipitation is probably less than 

10 inches annually; over much of the remainder the rainfall averages 

between 10 and 15 inches, and in only a very small area in the high 

mountains does the annual precipitation exceed 20 inches.

Throughout this basin the winters are severe and most of the 

streams have a heavy ice cover for several months. There is usually 

an abundance of snow in the high mountains, but the winters on the 

plains are frequently open.

The waters of the Green and its tributaries are practically unused 

except for irrigation. From Wells, Wyo., to the Wyoming State line, 

a distance of 225 miles, the stream has an average fall of 11 feet to 

the mile; and from the Wyoming State line to the mouth of Minnie 

Maud Creek, a distance of 200 miles, the average fall is 7 feet to the 

mile. Along these two sections of the river and on the headwaters 

there are many unutilized power sites.

From the junction of Green and Grand rivers the Colorado flows 

southwestward, passes across the northwestern corner of Arizona, 

then turns to the south, and for the remainder of its course forms a 

part of the southeastern boundary of Nevada and California and the 

western boundary of Arizona. It empties into the Gulf of California 

about 60 miles below Yuma, Ariz. The canyons through which it 

flows are world famed and need not here be described.

The Colorado has been called the Nile of America, and, like the Nile, 

it is subject to an annual summer rise which .comes at the time the 

water is most needed for irrigation. It is of interest to compare the 

Colorado with the Nile and the Susquehanna. The Nile is similar in 

type; the Susquehanna shows the difference in flow between arid and 

humid regions. In the comparison a normal year, based on a 10- 

year record for Colorado and Susquehanna rivers and such data as 

could be found in regard to the Nile, have been used. The Colorado 

has been taken as the standard of comparison.^

The Nile has 5.7 times the drainage area and the Susquehanna 

about one-eighth the area of the Colorado.

The rainfall in the Nile basin is 3.8 times greater; that in the Susquehanna basin is 4.5 times greater. The run-off per square mile from 

the Nile basin is 1.9 times greater; that from the Susquehanna basin 

is 37 times greater. The ratio of run-off to rainfall in the Nile basin 

is 2 times smaller; that of the Susquehanna basin is 8.2 times greater.

The discharge of the Nile is 10.8 times greater; that of the Susquehanna is 4.5 times greater.
COLORADO RIVER BASIH. 27

The maximum flow of the Colorado is from 50,000 to 150,000 

second-feet and occurs in May, June, or July; for the Nile it is about 

353,000 second-feet and occurs about the first of September; for the 

Susquehanna it is from 150,000 to 550,000 second-feet and occurs 

during March, April, and May.

The minimum flow of the Colorado is from 2,500 to 3,000 secondfeet and occurs during January and February; that of the Nile is 

about 14,500 second-feet and occurs about the end of May; for the 

Susquehanna it is from 2,200 to 11,000 second-feet and occurs in 

September and October.

The mean flow of the Colorado for the period 1894-1903 is 10,700 

second-feet, as previously published. The mean flow for the period 

1904-1910, however, is 25,400 second-feet; for the Nile it is about 

115,800 second-feet; for the Susquehanna it is about 41,000 secondfeet.

GREEN RIVER NEAR, KENDALL, WYO.

This station, which is located just above the mouth of Gypsum 

Creek and at the Kendall forest ranger station, was established August 

3, 1910.

Gage heights are obtained from chain gage.

Discharge measurements are made from a cable and car.

The stream bed is composed of small rounded bowlders and is 

probably permanent.

During the winter the relation between gage heights and discharge 

is probably affected by slush ice which collects on a riffle below the 

station.

This station is maintained in cooperation with the Forest Service, 

by which the gage heights are furnished.

GKREEN RIVER AT GREEN RIVER, UTAH.

This station, which is located at the highway bridge 200 feet 

upstream from the Rio Grande Western Railway bridge at Green 

River railroad station, near Elgin post office (originally called Blake), 

was established October 21, 1894, discontinued October 15, 1899, and 

reestablished in February, 1905. The gage was moved December 2, 

1910, from the railroad bridge to the highway bridge, 200 feet 

upstream. Its datum is the same as that of the old gage at 5.53 feet.

A new bridge was erected at this point between the periods of maintenance of the original station and the present one. The datum of 

the gage maintained up to December 2,1910, as near as can be learned, 

is 1.68 feet below the original datum and has remained the same since 

its establishment; but owing to the change in conditions of flow 

caused by the relocation of the bridge piers, it is impossible to utilize 

the early measurements in studies of new discharge curves.

Price River enters from the west about 16 miles above the station. 

Several irrigation projects are completed and being promoted in this 

drainage basin. The last ditch above the station on the right bank 

is about 6 miles upstream and on the left bank about 3 miles upstream.

Discharge measurements, which were formerly made from the railroad bridge and from a ferryboat, are now made from the highway 

bridge, where conditions favor accurate measurements. This bridge 

divides the measuring section into three parts, each 168 feet wide. 

The channel is somewhat shifting.

A careful determination, in 1909, of the angle which the bridge 

makes with the main current, necessitated a correction of 15 per cent 

in all discharge measurements made at the bridge from 1905 to 1910. 

The daily and monthly estimates of discharge for 1905 to 1909 have 

been revised and supersede those previously published.1

Ice usually exists at the station during December, January, and 

February. Monthly estimates during these periods have been 

obtained by considering the general behavior of the river at this station and by the aid of climatologic data.

GREEN RIVER AT LITTLE VALLEY, UTAH.

This station, which is located at Little Valley, Utah, 6 miles downstream from the old station at Green River railroad station, near 

Elgin post office, was established December 18,1910. No tributaries 

enter between these two stations except a few washes which carry 

water during floods.

Measurements are made from a ferry cable (PI. Ill, A).

The gage is on the left bank, 100 feet upstream from the ferry, and 

is in two sections, a vertical staff for low-water and a slope gage for 

high-water readings.

The stream bed consists of loose sand overlying gravel and is liable 

to change during high water.

The following discharge measurement was made by G. H. Canfield:

December 18, 1910: Width, 310 feet; area, 1,030 square feet; gage height, 0.90 feet; 

discharge, 2,180 second-feet.

The following additional gage heights were obtained: 

December 19, 0.9 foot; December 20, 0.75 foot; December 21, 0.6.

COLORADO RIVER AT YUMA, ARIZ.

This station, which is located in the town of Yuma, Ariz., 1J miles 

below the mouth of Gila River and 10 miles by river above the Mexican border, furnishes information concerning the amount of water 

available for irrigation along tne lower Colorado River. Records of 

river height have been kept by the Southern Pacific Co. since April 1, 

1878.

At Laguna dam, 14 miles above the station, approximately 60 

second-feet is diverted for irrigation on the California side. At

A. GAGING STATION ON GREEN RIVER AT LITTLE VALLEY, UTAH.

B. UPSTREAM VIEW OF GILA RIVER FROM RAILROAD BRIDGE AT GUTHRIE, ARIZ. 

About 500 feet below the gaging station.
COLORADO RIVER BASIN, 31

Yuma below the station, an average of 100 second-feet is pumped from 

the river for irrigation in the Yuma Valley. At the Imperial canal 

headworks, 6 miles below Yuma, approximately 1,500 second-feet is 

diverted for use in Imperial Valley.

The records given herewith are furnished by the United States 

Reclamation Service, through F. L. Sellew, project engineer, Yuma, 

Ariz.

The gage is a vertical staff, in two sections, the upper section, reading above 24 feet, being the original gage established in 1876. It is 

located at the railroad bridge, 600 feet above the cable station. The 

elevation of the zero of the gage is 102.79 feet above sea level.

As the bed of the stream is composed of silt and sand and is very 

unstable, frequent measurements are necessary to properly determine 

the daily discharge. Neither bank is subject to overflow. Previous 

to May 31, 1903, discharge measurements were made from the railroad bridge". On that date a cable station was established at a point 

600 feet below the bridge, and all measurements are now made from 

a car, except during highest floods, when a boat is used. At flood 

stages a large part of the water flows through an old channel and 

does not pass under the cable. At such times this overflow water is 

measured at the point where it passes under the railway trestle, onethird mile north of the main channel.

TRIBUTARY BASINS. 

NEW FORK RIVER BASIN. 

GENERAL FEATURES.

New Fork River and its tributaries drain a portion of the western 

slopes of the Wind River Range, extending from Fremont Peak 

southeastward to Mount BonnevUIe, Mount Geikie, and Twin Buttes. 

The main stream flows in a general southerly course to a point near 

Cora, Wyo., where it turns sharply to the southwest, joining Green 

River about 40 miles below.

Pine, Pole, and Boulder creeks and East Fork River are the chief 

tributaries of the Newfork. These are all small streams, heading far 

back among the high peaks of the range and fed by the numerous 

springs and small mountain lakes with which the region is dotted. 

Fremont, Boulder, Fayette, Half Moon, Burnt, and Meadow lakes 

are the largest and most important of these. Fremont Lake, through 

which Pine Creek flows, has an area of approximately 2,500 acres.

The upper portions of the valleys of all these streams are forested 

and the valleys and rolling bench lands are covered with sagebrush 

and a sparse growth of nutritious grasses. The soil of the foothill 

region is sandy and gravelly in character, gradually becoming a rich 

loam at the lower levels.

NEW FORK RIVER NEAR CORA, WYO.

This station, which is located at the ranch of Eugene Alexander, 

3J miles below the outlet of New Fork Lake, was established July 29, 

1910. A station was maintained on this stream 12 miles below the 

present site during 1905, but, as several tributaries enter and several 

ditches take water between the two sites, the records are not comparable.

Practically no water is diverted between the present station and 

New Fork Lake, and the records therefore indicate the amount of 

water available for storage'in the lake.

The gage is a vertical staff. Discharge measurements are made by 

wading.

The following measurement was made by G. C. Baldwin:

September 23, 1910: Width, 24 feet; area, 11 square feet; gage height, 1.21 feet; 

discharge, 6.6 second-feet.

PINE CREEK NEAR PINEDALE, WYO.

Pine Creek, designated Fremont Creek on the earlier maps, rises 

on the southern slope of Fremont Peak, near the top, and flows 

southwestward about 25 miles to its junction with New Fork River. 

Its drainage area comprises 130 square miles, about 60 square miles 

being covered with forest. From its source to a point about 2 miles
36 SURFACE WATER SUPPLY, 1910, PART IX.

beyond Fremont Lake, through which it flows, it is a winding stream 

descending by a series of falls and rapids, almost impassable even at 

low water.

The gaging station, which is located at an old Indian fording place 

below the outlet of Fremont Lake, about 4£ miles by wagon road from 

Pinedale and 115 miles from Rock Springs station, on the Union 

Pacific Railroad, was established July 22, 1910. A station described 

under the same name was maintained during 1904-1906 at a point 

about 1£ miles below the present station. Two ditches divert water 

from the stream between the old and the new sites.

A staff gage was installed July 22, 1910, and was reset September 

26, 1910, at a different location. On September 20, 1910, a permanent chain gage was installed on the left bank.

tligh-stage measurements are made from a cable 50 feet below the 

chain gage; low-stage measurements are made by wading.

Gage heights are furnished by the Forest Service.

The following discharge measurement was made by G. C. Baldwin:

September 20, 1910: Width, 71 feet; area, 45 square feet; gage height, 1.72 feet; 

discharge, 36 second-feet.

POLE CREEK NEAR PINEDALE, WYO.

Pole Creek rises on the southwestern slope of New Fork Peak, 

flows southwestward, and unites with New Fork River about midway 

between the points at which that stream is joined by Pine Creek and 

East Fork River. It is fed by numerous small lakes, of which Fayette and Half Moon lakes are the largest.

The gaging station, which is located just below the mouth of Fall 

Creek and about 5 miles from Pinedale, Wyo., was established 

July 25, 1910.

One ditch diverts water from Pole Creek above the present station.

A chain gage is fastened to the right bank of the stream.

Measurements are made by wading at all stages. ^
COLORADO RIVER BASIN.

From 1904 to 1906 a gaging station was maintained on Pole Creek 

about 1£ miles above the present site and above the mouth of Fall 

Creek, the outlet of Burnt Lake. During 1904 and 1905 a station 

was maintained on Fall Creek three-fourths of a mile above its 

mouth. The records obtained at the present station indicate the 

amount of water flowing from Pole Creek and Burnt Lake and 

available for power development.

the State engineer.

A vertical staff gage is spiked to an old bridge abutment.

A sandstone outcrop immediately below the station gives good control 

to the section. The stream channel is practically dry part of the year.

Low-stage measurements are made by wading. High-stage discharge is computed by means of Kutter's formula.

YAMPA RIVER BASIN. 

GENERAL FEATURES.

Yampa River rises in Egeria Park, in the southeastern part of 

Routt County, Colo., runs in a general northerly direction to Steamboat Springs, and thence westward to its point of junction with 

Green River, just east of the Colorado-Utah State boundary. 

Through almost its entire course it flows in a succession of open 

valleys alternating with deep, narrow canyons, the longest and 

deepest of the canyons being that through which it enters the Green.

The drainage basin of the river lies for the most part within the 

boundaries of Routt County, which is a little larger than the State of 

Massachusetts and comprises about 6,000 square miles. Its eastern 

limit is formed by the Park Mountains. Westward from the mountains the basin is largely the eroded and dissected Yampa Plateau, 

whose wide terraces, abrupt cliffs, and deep-cut gulches and arroyos 

are the striking features of the region. The general level is over 6,000 

feet above sea.

Elk River, Fortification Creek, Elk Head Creek, William River, and 

Little Snake River are the most important tributaries of the Yampa. 

The upper basins of these streams are within the forested region, but 

along their lower courses are many cultivated areas.

YAMPA RIVER AT YAMPA, COLO.

This station, which is located at the footbridge on the road between 

Yampa River and the Denver, Northwestern & Pacific Railway station, was established May J7, 1910, by the State engineer of Colorado, 

by whom the records are furnished.

A vertical staff gage is spiked to the upstream side of the footbridge.

The current makes an angle of about 15 degrees with the bridge. 

The bed of the stream affords fair conditions for discharge measurements.
42 SURFACE WATER SUPPLY, 1910, PART IX.

Discharge measurements are made from the downstream side of 

the wagon bridge just above the footbridge.

The relation between gage height and discharge is affected by ice 

during the winter months.

YAMPA EIVEE AT STEAMBOAT SPEINGS, COLO.

This station, which is located at the lower steel bridge at the Denver, Northwestern & Pacific Railway station, Steamboat Springs, 

Colo., was established March 3, 1910, by the State engineer of Colorado, by whom the records are furnished.

A standard chain gage and a Bristol automatic gage, both referred 

to the same datum, are attached to the bridge.

The bed of the stream is composed of cobbles and bowlders and is 

permanent. Conditions favor accurate measurements.
44 WATER SUPPLY, 1910, PART IX.

Discharge measurements are made at the steel bridge between the 

railroad station and the town.

The relation between gage height and discharge is little affected by 

ice, as the hot springs above the station tend to keep the river open 

most of the winter.

During 1904, a station was maintained on the Yampa at a highway bridge about three-quarters of a mile above the present station, 

and in 1905 a station was maintained at a point half a mile below 

the present site. The gages are, however, not referred to the same 

datum and the records are not comparable.

YAMPA RIVER NEAR MAYBELL, COLO.

This station, which is- located at the Thornberg bridge, about 9 

miles below Maybell, Colo., was established by the United States 

Geological Survey April 17, 1904, and discontinued October 31, 1905; 

it was reestablished June 12,1910, by the State engineer of Colorado, 

by whom the records are furnished.
48 SURFACE WATER SUPPLY, 1910, PART IX.

The chain gage is attached to the downstream handrail of the 

bridge. The datum of the new gage is identical with that of the old.

Discharge measurements are made from the bridge.

During the winter the relation of gage height to discharge is 

affected by ice.

TROUT CREEK AT PINNACLE, COLO.

This station, which is located at a wagon bridge one-fourth mile 

above Pinnacle, 11 miles fiom Dunkley, and 17 miles from Yampa, 

Colo., was established April 9, 1910, by the State engineer of Colorado and is maintained by the State in cooperation with the Williams 

River High Line Irrigation Co.

A rod gage is fastened to the left bank 10 feet below the bridge.

High-stage measurements are made from the bridge; low-stage 

measurements are made by wading at various sections.

During the winter the relation between gage height and discharge 

is affected by ice.

SODA CREEK AT STEAMBOAT SPRINGS, COLO.

This station, which is located at a road bridge on Main Street, 

Steamboat Springs, was established June 8, 1910, by the State engineer of Colorado, by whom the records are furnished.

A chain gage is fastened to the bridge.

The bed of the stream is composed of cobbles and is permanent. 

The current makes an angle of 35° with the bridge; a coefficient of 

0.81 has been used in correcting the discharge estimates. The measuring section is good.

Discharge measurements are made from the bridge.

The relation of gage height to discharge is affected by ice during the 

winter.

ELK RIVER NEAR TRULL, COLO.

This station, which is located at the steel bridge about 2 miles southeast of Trull on the road between Steamboat Springs and Hayden, 

Colo., was established May 2, 1904, by the United States Geological 

Survey, discontinued August 16, 1906, and reestablished March 24, 

1910, by the State engineer of Colorado, by whom the records are 

furnished.

The original gage, a vertical rod, was replaced by a chain gage, 

installed at the same datum, June 22, 1904. The present chain gage 

is the same as that used by the United States Geological Survey. It 

is attached to the bridge, no change having been made either in the 

location or in the datum.

Discharge measurements are made from the bridge.

During the winter months the relation between gage height and 

discharge is affected by ice.

FISH CREEK AT DUNKLEY, COLO.

This station, which is located at the wagon bridge, one-fourth 

mile below Dunkley's ranch and one-half mile above Dunkley's 

reservoir dam site, was established April 8, 1910, by the State engineer 

of Colorado, and is maintained by the State in cooperation with the 

Williams Kiver High Lane Irrigation Co. The records are furnished 

by the State engineer.

High-stage measurements are made from the bridge; low-stage 

measurements are made by wading at various sections.

During the winter months the relation between gage height and 

discharge is affected by ice.

ELK HEAD CREEK NEAR CRAIG,, COLO.

This station, which is located at a wagon bridge at Harrison's ranch, 

about 6 miles above Craig, Colo., on the road from Steamboat Springs 

to Craig, was established by the United States Geological Survey, 

April 27, 1906, discontinued September 2, 1906, and reestablished 

April 15, 1910, by the State engineer of Colorado, by whom the 

records are furnished.

A chain gage is attached to the bridge. The location and datum 

of the present gage are identical with those of the original gage.

High-stage measurements are made from the bridge; low-stage 

measurements are made by wading at various sections.

During the winter months the relation between gage height and 

discharge is affected by ice.

WILLIAMS RIVER NEAR PYRAMID, COLO.

This station, which is located at a footbridge at Dunston's ranch, 

3 miles below Pyramid post office, was established April 14, 1910, 

by the State engineer of Colorado in cooperation with the Williams 

River High Line Irrigation Co. The records are furnished by the 

State engineer.

A vertical staff gage is bolted to the crib pier of the footbridge.

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

probably permanent. The left bank is overflowed at high water. 

The measuring section is good.

Discharge measurements are made from the bridge.

The relation between gage height and discharge is affected by ice 

during the winter months.

WILLIAMS RIVER AT HAMILTON, COLO.

This station, which is located on the steel wagon bridge on the 

stage road between Craig and Meeker, three-fourths of a mile north 

of Hamilton post office, about 14 miles from Craig, Colo., was 

established by the United States Geological Survey April 29, 1904, 

discontinued October 31, 1906, and reestablished April 15, 1910, 

by the State engineer of Colorado, by whom the records are furnished.

A standard chain gage is attached to the bridge. The datum of 

the present gage is 0.18 foot lower than the datum of the original 

gage.

The bed of the stream consists of gravel and some small bowlders 

and is probably permanent. The measuring section is good.

Discharge measurements are made from the downstream side of 

the bridge.

The relation between gage height and discharge is affected by ice 

during the winter.

LITTLE SNAKE RIVER AT DIXON, WYO.

This station, which is located at the steel highway bridge 1 mile 

west of Dixon, Wyo., was established May 28, 1910, by the State 

engineer of Colorado, by whom the records are furnished.

A chain gage is attached to the upstream handrail of the bridge.

High-stage measurements are made from the bridge; low-stage 

measurements are made by wading at various sections. Discharge 

measurements must be corrected to eliminate errors caused by the 

angle at which the current passes beneath the bridge.

The relation between gage height and discharge is affected by ice 

during the winter months.

DTTCHESNE RIVER BASIN. 

GENEEAL FEATUEES.

Duchesne River rises in the high peaks of the Uinta and Wasatch 

mountains in northeastern Utah, flows for about 100 miles in a general 

southeasterly direction, and enters Green River at Ouray, Utah, about 

3 miles above the mouth of White River. The stream has a total 

drainage area of 4,000 square miles. Altitudes range from 4,700 feet 

at the mouth of the river to more than 13,000 feet at the summits of 

the highest peaks.

The principal tributaries of the Duchesne are Rock (East) Creek, 

Strawberry River, Lake Fork, and Uinta River.

The drainage basin of the upper Duchesne proper is mountainous. 

The stream emerges from the mountains at the mouth of Rock Creek, 

at an elevation of a,bout 6,000 feet. From the mouth of Strawberry 

River down to Lake Fork the valley of the Duchesne is about 2 miles 

 in average width and is bordered by sandstone bluffs approximately 

200 feet high. Along the lower course of the stream the plateaus on 

each side of the stream valley are comparatively low and can be easily 

reached by irrigation canals from the main stream.

Strawberry River, the main upper tributary of the Duchesne, rises 

in the Uinta Mountains and enters the Duchesne at Theodore. It 

drains an area comprising about 1,200 square miles. The upper 

stream basin has numerous tributaries, particularly from the north 

and west. Among the most important may be mentioned Indian 

Creek, Bryant's Fork, Mud Creek, Horse Creek, Sugar Springs, and 

Co-op Creek. All are short and all fall rapidly until they reach Strawberry Valley, through which they flow sluggishly in well-defined 

channels. The main stream traverses the valley from north to south 

and is very sluggish. As its average elevation is 7,500 feet above sea 

level, Strawberry Valley is not well suited for agricultural develop-
COLORADO BIVER BASIN. 71

ment, but it is excellently adapted to grazing. At the mouth of the 

river, about 35 miles below Strawberry Valley, the elevation is about 

5,500 feet, and the fall in that distance is, therefore, nearly 2,000 feet.

Rock Creek, Lake Fork, and the Uinta and its most important 

tributary, the Whiterocks, head in a series of small snow-fed lakes in 

the Uinta Mountains and drain areas mountainous and difficult of 

access, and emerge from their canyons at an elevation of about 

7,000 feet.

The drainage area of the Duchesne includes about 1,400 square 

miles of forest reserve, of which about 1,000 square miles may be 

classed as timbered land. The timbered land is distributed through 

the areas of the tributaries about as follows: Upper Duchesne, 120 

square miles; Rock Creek, 130 square miles; Strawberry River, 380 

square miles; Lake Fork, 190 square miles; Uinta (above Whiterocks) 

120 square miles; Whiterocks, 70 square miles.

In the plains area the average rainfall is probably less than 10 

inches; in the middle part comprising considerably over half the area, 

it probably averages between 10 and 15 inches; in only a small 

part in the high mountains is there an annual precipitation in excess 

of 20 inches, and at Fort Duchesne, at an elevation of 5,000 feet, a 

record extending over several years shows a mean annual rainfall of 

only 7 inches. The winters are very severe. In the high mountains 

the snowfall is heavy, and in many places the snow lies through the 

whole year. AH the streams in this region are usually covered with 

thick ice from about December 1 to April 1 of each year.

At the present time the water in these streams is unused except for 

irrigation. Practically no storage is used in connection with any of 

the irrigation systems now in operation or under construction, but 

as the mountain drainage areas of all the main tributaries are studded with lakes, reservoir sites can easily be found where water can 

be stored for the irrigation of the valley lands.

The United States Reclamation Service is constructing a tunnel, 

with a capacity of 500 second-feet, which will divert water from a 

100,000-acre reservoir on the upper Strawberry across the divide to 

the headwaters of the Spanish Fork, there to be used for irrigation.

Very little water will be diverted for irrigation above an elevation 

of 6,500 feet, and as most of the reservoir sites are at an elevation 

of 8,000 feet or more, and some of the streams fall 100 to 150 feet 

or more to the mile in their upper stretches, good opportunities for 

power development exist above irrigation ditches.

DUCHESNE RIVER AT MTTON, UTAH. 1

This station, which was located at the highway bridge at Myton, 

Utah, about 3 miles below the mouth of Lake Fork and about 15

i Described in the earlier reports as the Price Road Bridge station.
SURFACE WATER SUPPLY, 1910, PART IX.

miles above the mouth of Uinta River, was established October 26, 

1899. The records show practically the entire run-off of the Duchesne 

basin above the mouth of Uinta River.

The datum of the gage remained practically constant from the 

establishment of the station until June 6, 1909, when the river cut a 

new channel around the bridge and the bridge station was abandoned. 

A new chain gage was established July 9, 1909, about one-fourth of a 

mile upstream from the bridge and at a different datum. This gage 

was replaced on August 9, 1909, by another chain gage 100 feet 

downstream on right bank, at the same datum.

A chain gage was installed August 6, 1910, on the new single-span 

steel bridge across the river. This bridge is located near the northwest boundary of the Myton town site, about one-fourth of a mile 

upstream from the old gage and half a mile upstream from the original 

location at the wooden bridge.

There was no bridge or cable from which discharge measurements 

could be made during the latter part of 1909 and first part of 1910.

Discharge measurements are also made from the new bridge.

Ditches built by the United States Indian Office divert water from 

this stream and its tributaries for irrigation on the Uinta Reservation. Water is also diverted by private enterprise for irrigation outside the limits of the reservation.

Observations at this station are affected by ice for about four 

months each year, and during this period it is usually impossible to 

apply open-channel ratings.

NOTE. Gage established at new location and datum Aug. 6, 1910; the reading that day was 2.10 feet. 

For measurements from Aug. 6 to Oct. 22, both gages were read and the new gage was found to read about 

2.7 feet lower than the old gage, which was established Aug. 9,1909. For the measurements made Nov. 6 

and Nov. 19, the new gage only was read, so the readings were made to conform to the old gage by adding 

2.7 feet.

STRAWBERRY RIVER ABOVE MOUTH OF INDIAN CREEK, IN STRAWBERRY VALLEY, UTAH.

A station was established on Strawberry River September 15, 

1909, in the narrows about 3 miles above the mouth of Indian 

Creek and about one-quarter mile below the dam site of the Strawberry Valley project, to determine the amount of water available for 

storage from Strawberry River for the Strawberry Valley project of 

the United States Reclamation Service. The station takes the place 

of the one previously maintained below Indian Creek. The new 

station is about 35 miles northeast of Thistle, Utah, the nearest railroad point. The drainage area above this station is 132 square miles.

The vertical staff gage is on the right bank directly underneath the 

cable from which discharge measurements are made.

Neither bank is likely to be overflowed except at extreme high 

water. The stream bed consists of coarse gravel and although rough 

is believed to be fairly permanent. The conditions for measuring 

during the open-water season are good.

The river is frozen and deeply covered with snow about five months 

of the year. The flow during the winter is, however, fairly constant 

and a fair estimate of it may be made.

This station was discontinued November 15, 1910.

STRAWBERRY RIVER *AT THEODORE, UTAH.

This station, which is located at the west boundary of the Theodore 

town site, along the wagon road to Heber, about 1| miles above the 

junction of-the Strawberry with Duchesne River, about half a mile 

upstream from the mouth of Indian Canyon, and about 18 miles 

below the mouth of Currant Creek, was established June 10, 1908, 

and discontinued November 30, 1910. The drainage area above the 

station is 1,060 square miles.

The chain gage was located about 50 feet downstream from cable 

from which discharge measurements were made. The datum of the 

gage remained constant during the maintenance of the station.

The results obtained from observations at this station were good 

except at extremely high stages, when the stream overflows the left 

bank, rendering it impossible to make measurements.

INDIAN CREEK IN STRAWBERRY VALLEY, UTAH.

This station, which is located about 1 mile above the mouth of 

the creek and 500 feet below Trail Hollow Creek, the principal tributary, was established April 5, 1905, discontinued July 12, 1906, 

reestablished October 1, 1909, and again discontinued NovemberlS, 

1910. The station was originally located about 250 feet above the 

mouth of the creek, but was reestablished in 1909 about half a mile 

farther upstream, in T. 4 S., R. 11 W. It is about 25 miles northeast of Thistle, Utah.

This point is below all tributaries, Trail Hollow Creek entering a 

few hundred feet above the new station. No water is diverted above 

the station. The drainage area above this station is 50 square miles. 

The records are of value to the United States Reclamation Service in 

connection with the Strawberry Valley project, which will divert the 

waters of Indian Creek across a low pass into the Strawberry Valley 

reservoir. The point of diversion is above this station and below 

Trail Hollow Creek.

The staff gage is driven vertically into the bed of the creek and 

braced to the right bank about 10 feet above a new footbridge from 

which measurements are made.

The river is frozen over and covered with a deep layer of snow 

during about five months of the year. The winter flow, however, 

is fairly constant and a fair estimate may be made. The openwater measuring conditions are excellent.

TRAIL HOLLOW CREEK IN STRAWBERRY VALLEY, UTAH.

This station, which is located just above the mouth of the stream, 

was established October 1,1909, and discontinued November 15,1910. 

No water is at present diverted above the station. The records indicate the portion of the flow of Indian Creek that can not be diverted 

into Strawberry Valley in connection with the Strawberry Valley 

project. The drainage area above this point is 21 square miles.

The staff gage was driven vertically into the bed of the stream 

and braced to the left bank.

High-stage measurements were made from a log bridge 15 feet above 

the gage; at low and ordinary stages measurements were made by 

wading.

The stream is frozen over and deeply covered with snow during 

about five months of the year.

LAKE FORK BELOW FORKS, NEAR WHITEROCKS, UTAH.

This station, which is located about 500 feet downstream from the 

junction of the East and West forks, on the old Indian trail from 

Spanish Fork to Whiterocks, Utah, about 30 miles west of Whiterocks, was established on May 10, 1907, but a fragmentary record 

was maintained at the same place during 1904.

No important tributaries enter between this station and the mouth 

of the stream, and none on either branch for some distance above. 

The station is above all present diversions.

The flow of this stream could doubtless be equalized at comparatively small expense by utilizing the storage facilities afforded by a 

number of small lakes and reservoir sites found on both branches of 

the stream above the station. As both of the main tributaries have 

rapid fall, opportunities for power development are presented above 

all irrigation diversions. The drainage area above the station is 331 

square miles.

The stream is icebound for several months each year.

The chain gage established May 10, 1907, has no relation whatever 

to the 1904 gage. Still another chain gage and datum have been 

used since September 1, 1907. This gage is located about 100 feet 

upstream from the cable from which discharge measurements are 

made.

As the stream bed is rough and the current is swift at high and 

moderate stages, the results obtained at this station can be considered only fair or approximate except at low stages, when they are 

fairly good.

LAKE FOEK NEAE MYTON, UTAH. 1

This station, which is located about 3 miles above Myton, Utah, 

about half a mile above the junction of the s'tream with Duchesne 

River, was established July 3, 1900, discontinued at the end of the

1 Described in early reports as "Lafce Fork at mouth,"
COLORADO RIVER BASIN. 85

season of 1903, reestablished in June, 1907, and again discontinued 

November 30, 1910.

In connection with the records obtained at the station on Lake 

Fork below the forks, which is about 20 miles upstream and above 

all present diversions, the records indicate the amount of water 

diverted for irrigation along the stream. No important tributaries 

enter between the two stations.

Several canal systems built by the United States Indian Office 

take water from this stream above the station for irrigation. Some 

private canal systems are proposed or in operation. The stream is 

icebound for several months during the winter season.

The gage was in the same position and the same datum was used 

from 1900 to 1904, inclusive. During 1907 and 1908 three distinct 

gages and datums were used from June 13 to 30, 1907, from August 

18 to December 31, 1907, and during 1908. Very satisfactory results 

were obtained during 1908 and 1909, but previous records are not so 

good. On June 22, 1909, the gage was removed to the opposite bank 

and reinstalled at a different datum. Gage heights, beginning June 

22, 1909, are therefore not comparable with those of previous dates.

UINTA RIVER NEAR WHITEROCKS, UTAH.

This station, which is located at the highway bridge on the Government road up Uinta Canyon (usually known as the sawmill road), 

about 8 miles northeast of the Indian agency at Whiterocks, was 

established September 16, 1899, discontinued the latter part of 1904, 

reestablished August 13, 1907, and again discontinued November 30, 

1910.

Pole Creek enters about 5 mile above the station and Whiterocks 

comes in several miles below.

No water is diverted from the stream above the station, but the 

United States' Indian Office has constructed a series of irrigation 

canals which divert water at various points below.

The same gage was used from 1899 to 1904, inclusive. The gage that 

was established in August, 1907, was located a short distance upstream 

from the old gage and. at a different datum. The present chain gage 

has no determined relation to this last gage. It was established on 

October 22, 1907, on the bridge about a mile downstream from the 

other gate.

The gage was read only when the hydrographer visited the station 

to make discharge measurements, and the discharge for intermediate 

days is estimated by comparison with the hydrographs of other 

streams in that locality.

As the stream bed is rough and the current swift at high and 

moderate stages, the discharge measurements, except at low stages, 

are apt to be considerably in error.

The relation between gage height and discharge is affected by ice 

during the winter season. Winter measurements are usually taken 

at riffles or open places in the channel.

UINTA RIVER AT FORT DUCHESNE, UTAH. ^

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

road to Vernal, one-fourth of a mile from Fort Duchesne, Utah, was 

originally established on September 4, 1899, and continued until the 

end of 1904. It was also maintained for a brief period during 1906. 

The station was reestablished April 9, 1907, and again discontinued 

November 30, 1910.

The data obtained at this point show the "amount of water contributed by this stream to Duchesne River, except the comparatively 

small amount diverted for irrigation below, and in connection with the 

records of the stations above on the Whiterocks and the Uinta they 

show the amount of water taken for irrigation by the numerous 

ditches on the Uinta and Whiterocks above the station. The upper 

tributaries, above irrigation diversions, afford excellent opportunities 

for storage and power development.

Practically the same datum was used for the gage up to and 

including 1906. The chain gage established April 9, 1907, has an 

entirely different datum. This gage was fastened to the bridge from 

which discharge measurements were made.

The flow of the stream is affected by ice for about four months 

during the winter season, and the accuracy of the results is somewhat 

impaired by eddies around the crib piers and by deposits of sediment 

brought down by Deep Creek during floods.

WHITEROCKS RIVER NEAR WHITEROCKS, UTAH.

This station, which is located at the mouth of the canyon, at the 

foot of "Dugway," on the road from the plateau to the river bottom, 

about 10 miles above the Indian agency at Whiterocks, and below
92 SURFACE WATER SUPPLY, 1910, PART IX.

all important tributaries of the Whiterocks, was established April 18, 

1899, aild continued until the end of 1904. On April 11, 1907, it was 

reestablished at practically the same place and was again discontinued on November 30, 1910.

The nearest irrigation ditch is about 3 miles below the station. 

Excellent storage and power sites exist above all irrigation diversions.

The same gage and datum were used from the establishment of the 

station until the end of 1904. A new chain gage and datum were 

used from April 11, 1907, to May 8, 1908, and a second chain gage 

at a still different datum from May 9, 1908, to November 30, 1910.

Owing to the remoteness of this gage from any dwelling, daily gage 

observations have not been made, and the daily and monthly discharge tables have been computed by comparing the relatively frequent discharge measurements with the hydrographs of other streams 

in that section.

Measurements were made from a cable about 100 feet downstream 

from the gage. 

As the stream bed is rather rough and the current is swift, measurements at high or medium stages are not very accurate. Tfre daily and 

monthly discharge estimates, computed by the method outlined 

above, are necessarily only approximate.

Like other streams in this region, the river is icebound for several 

months in the winter.

WHITE BIVEB BASIN. 

GENERAL FEATURES.

White River rises in Trappers Lake, which lies 9,500 feet above 

sea level in a small mountain basin of the White River Plateau in 

eastern Garfield County, Colo., and flows westward to its junction 

with Green River in west-central Uinta County, Utah. Throughout 

its course it occupies a narrow mountainous valley, with alternating 

parks and canyons, entering the longest and deepest of the canyons, 

in which it continues to its mouth, about 8 miles east of the ColoradoUtah State line.

The basin comprises an arid, broken, and much eroded plateau 

region, which topographically is a continuation of the Grand River 

Mesa south of Grand River. The headwater portion covers the greater 

area and is called the White River Plateau; below this and to the 

south is the Roan or Book Cliffs Plateau. Fragmentary plateaus also 

occur along the northern side of the river.

Numerous small streams, among which are Marvine Creek and 

South Fork, join the White in the upper, mountainous portion of 

the basin. Douglas, Piceance, and Evacuation creeks, draining the 

Book Cliffs Plateau, enter White River from the south. In the 

spring these creeks carry considerable water, derived mainly from 

melting snow, but in the summer they are very nearly dry.

The mean annual precipitation recorded at Meeker is 15.9 inches; 

farther west and at lower elevations it is undoubtedly much less.

NORTH FORK OF WHITE RIVER NEAR BUFORD, COLOThis station, which is located at Genier's ranch, about 1£ miles 

above Buford, was established May 24, 1910, by the State engineer 

of Colorado, by whom the records are furnished. The station is 

about 5 miles below the site of a station established by the United 

States Geological Survey July 28, 1903, and discontinued October 

31, 1906. No large tributaries enter between the former and the 

present site.

A staff gage is spiked to the support of a footbridge.

The bed of the stream is composed of cobbles and bowlders and is 

permanent. The right bank is overflowed at extreme high stages. 

The measuring section is good.

Discharge measurements are made from the bridge.

The relation between gage height and discharge is affected by ice 

during the winter months.

and discontinued October 31, 1906.

A vertical staff gage is spiked to a pier of the road bridge. From 

May 29 to June 24, 1910, the State engineer's gage was located at a 

highway bridge one-half mile below Shephard's ranch. The relation 

between the two gages has not been determined.

The bed of the stream is composed of gravel and is fairly permanent. The left bank is overflowed at extreme high stages. The 

measuring section is good.

High-stage measurements are made from the bridge; low-stage 

measurements are made by wading.

The relation between gage height and discharge is affected by ice 

during the winter.

PRICE RIVER BASIN. 

GENERAL FEATURES.

Price River rises in the Wasatch Mountains in the southeastern part 

of Utah County, flows southeastward, and unites with Green River 

at a point about 14 miles above Green River, Utah. The main source 

of supply is the snow in the upper reaches of the basin, where elevations range from 8,000 to 9,000 feet. The basin comprises about 1,500 

square miles of extremely rough and rugged country. The predominant rock is a loose and badly disintegrated sandstone. The soil is 

scanty and supports practically no vegetation except small groves of 

scrubby cedar and a few scattered pines. The original sparse underbrush and grass have been almost entirely tramped out by sheep and 

cattle.

The river is subject to floods in the spring and early summer, during 

which time it carries immense quantities of sediment. Gordon and
OOLOEAIK) RIVER BASIN. 101

Pleasant creeks, the principal tributaries, are both short, steep 

streams and enter from the west almost at right angles.

PRICE RIVER NEAR HELPER, UTAH.

This station, which is located at an old ford crossing in the settlement of Spring Glen, about 3 miles south of Helper, Utah, and about 

350 feet west of the tracks of the Denver & Rio Grande Railroad, was 

established February 21, 1904.

This station is below Pleasant Creek and White River, the two 

principal tributaries above, and is above Gordon Creek, which enters 

about 5 miles below, and Grassy Trail Creek, which enters about 35 

miles below. There are no important diversions above.

The datum of the original chain gage remained unchanged until the 

gage was washed out by high water April 11, 1907. It was replaced 

by a temporary gage June 23, 1907, and by a permanent gage July 

16, 1907. All gage heights after June 22, 1907, are referred to a new 

datum 0.7 foot above the original datum.

Discharge measurements are made from a car and cable.

A fair estimate may be made of winter flow, though ice is usually 

rather heavy. The bed of the stream is somewhat shifting, but the 

records may, on the whole, be considered good.

PRICE RIVER AT WOODSIDE, 'UTAH.

This station is located at the Denver & Rio Grande Railroad 

bridge crossing Price River at Woodside, about 8 miles downstream 

from a proposed diversion dam for an irrigation project and about 15 

miles above the junction of the Price with Grand River. By-making 

due allowance for a few small tributaries entering the river between 

the dam site and station the records at this point will indicate the 

available water supply for that project.

Gage heights are obtained by measuring from a fixed point on the 

bridge to water surface.

These data are published as furnished by Mr. H. W. Sheley, a 

consulting engineer of Salt Lake City, Utah.

NOTE. All measurements during 1909 and that on Nov. 13,1910, were made with floats; other measurements in 1910 were made with a current meter. All float measurements have been reduced by applying a 

coefficient varying from 0.85 to 1.0. Gage heights represent depths of water surface below a fixed point on 

Denver & Rio Grande Railroad bridge.

SAN RAFAEL RIVER BASIN.

GENERAL FEATURES.

San Rafael River is formed in the western part of Emery County, 

crosses the central part of the county in a general southeasterly direction, and enters Green River about 36 miles below the mouth of the 

Price. The river has three principal branches, Ferron, Cottonwood, 

and Huntington creeks, which rise in the Wasatch Plateau at altitudes of about 10,000 feet above sea level. These streams fall rapidly 

in their upper courses and leave the plateau through almost impassable canyons cut in its eastern wall overlooking Castle Valley. They 

unite below Castledale, and the stream formed by their combined 

waters flows southeastward through the San Rafael Swell in a deep, 

narrow canyon, from which it emerges to flow across a low, broken 

country to its junction with the Green. The water of this river is 

derived chiefly from the melting snow on the high plateau. The 

drainage area of this basin is 2,390 square miles.

SAN RAFAEL RIVER NEAR GREEN RIVER, UTAH.

This station, which is located at the county bridge on the road from 

Green River to Hanksville, about 16 miles southwest of Green River, 

Utah, and about three-fourths of a mile below the Morris ranch dam, 

was established May 5, 1909. It is below all important tributaries 

and diversions.

The staff gage is nailed securely to the southwest pier of the bridge 

from which discharge measurements are made. The gage datum has 

remained unchanged since the station was established.
COLORADO RIVER BASIN, 105

The winter flow is affected by ice, and as the bed of the stream 

shifts somewhat frequent measurements must be made in order to 

get satisfactory records.

COTTONWOOD CREEK NEAR ORANGEVILLE, UTAH.

This station, which is located at Johnson's ranch in the canyon 

about 5 miles northwest of Orange ville, Utah, and about 35 miles 

southwest of Price, the nearest railway point, was established May 1, 

1909.

The station is below all important tributaries and above all diversions except Johnson's ditch, which takes out a small amount of 

water a short distance above the station.

Previous to August 22, 1909, the stage was recorded by measuring 

to the water surface from a reference point on a cottonwood tree 60 

feet above the cable. A staff gage was installed August 22, 1909, at 

the same point, and all previous observations were corrected to the 

datum of this gage. During the flood of August 31 this gage was 

washed out. From September 1 to 17 the record was kept of the
COLOEADO'BIVEB BASIN. 107

water depth at the gage site. From September 20 observations were 

made of the distance to water surface from a mark on a rock at the 

site. All gage heights for 1909 have been reduced to the datum of 

the staff gage. On March 22, 1910, a slope gage was installed at a 

datum 0.8 foot lower than that used in 1909.

Discharge measurements at high stages are made from a cable 60 

feet below the gage site. At low stages by wading at various sections above and below gage.

As the stream bed shifts, accurate determination of discharge is 

difficult. Heavy ice forms at this station during the winter months.

NOTE. Gage heights Jan. 1 to Mar. 31 are not published, as they are very uncertain. During part of this 

period the observer recorded distances to water surface from a mark on a rock, and later recorded the 

depth of water at some point not indicated. The date on which he changed from one method to the 

other is not known.

A slope gage was installed Mar. 22 at a datum 0.8 foot lower than that used in 1909, but this gage was not 

read until Apr. 1.

FERRON CREEK NEAR FERRON, UTAH.

This station, which is located at Westingskow's ranch, about half 

a mile below the headgates of North and South canals, near the 

mouth of the canyon, about 2J miles above the town of Ferron, Utah, 

and below all important tributaries, was established April 28, 1909.

The drainage area is 153 square miles.
COLORADO RIVER BASIN. 109

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

station by the North and South canals, only enough water passing 

to supply one or two small ditches that take out below.

Several gages were used during 1909, all located in the same section. All gage heights were referred to- one datum until August 31, 

when a flood destroyed the gage and bench mark and greatly changed 

the section. From September 1 to December 31 all gage heights 

refer to a new gage which was installed September 18, 1909, at a 

new datum.

Discharge measurements are made from a footbridge about 10 

feet above the gage or by wading. Shifting of the stream bed 

makes it difficult to obtain accurate discharge records. The stream 

is icebound during the winter.

HUNTINGTON CREEK NEAR HUNTINGTON, UTAH.

This station, which is located at Cunha's ranch, in the canyon 

about 7 miles northwest of Huntington, Utah, was established May 

3, 1909.

The ditch for the Cunha ranch diverts a small amount of water a 

short distance above the station; practically all the normal low-* 

water flow is diverted for irrigation by canals heading near Huntington. This station is located below all principal tributaries and above
COLORADO RIVER BASIN. Ill

all the main diversions. A storage reservoir above the station controls the distribution of the flow to a considerable extent.

The vertical staff gage is in two sections. The low-water part is 

nailed to an old bridge abutment on the right bank about 3 feet from 

the cable; the high-water section is nailed to the west face of a cottonwood tree near the low-water section. The gage datum has remained 

unchanged since the station was established.

Discharge measurements are made from a cable.

The relation between gage height and discharge at this station is 

not seriously affected by ice. The shifting of the stream bed during 

the spring high water and summer floods impairs the reliability of 

the records.

Apr. 17 to May 21, indirect method for shifting channels used; May 22 to Dec. 31, rating curve well defined 

below 20 second-feet. Discharge estimated Aug. 1 to 14. Discharge interpolated for days of missing gage 

heights.

Ice not reported in 1910, but may have existed in January and February, and the use of the open-water

COLORADO RIVER BASIN. 113 

GRAND RIVER BASIN. 

GENERAL, FEATURES.

Grand River and its tributaries drain an area comprising approximately 26,000 square miles, of which 22,300 is in Colorado and the 

rest in eastern Utah. On the east and southeast the basin is bounded 

by the high ranges of the Continental Divide^ which separate it from 

the basins of Platte and Arkansas rivers; on the north it is limited 

by the White River and Book Cliffs Plateau, on the west by the 

canyon district of the Colorado.

Rising among the high peaks of the Rocky Mountains in the northcentral portion of Colorado, the Grand flows southwestward to its 

junction with Green River, traversing approximately 350 miles. 

Its tributaries include Fraser, Blue, Eagle, Williams, and Roaring 

forks and Gunnison and I)olores riyers, all of which enter from the 

south.

In most respects the Grand is a typical mountain stream, flowing 

throughout its course in a succession of deep canyons, whose precipitous or even perpendicular walls range in height up to 3,000 feet 

above the water's edge, alternating with long, narrow fertile valleys. 

The headwater region, comprising approximately 50 per cent of the 

basin, is extremely rugged, elevations ranging from 7,000 to 14,000 

feet above sea level. Stream channels are numerous, tributaries are 

rapid, and gradients are steep, the fall ranging from 20 to 150 feet 

to the mile. The intermediate or middle portion of the basin that 

portion immediately east and west of the Colorado State line is a 

dry, broken, much eroded region.

The precipitation ranges from 5 to 10 inches in the lower basin, 

10 to 20 inches in the intermediate region, and 2D to 30 inches in the 

headwater region. By far the greater part of the precipitation is 

in the form of snow.

The greater part of the timbered area in the Grand River basin 

above the Gunnison is included in the Arapahoe and Holy Cross 

national forests. These reserves in the Grand drainage basin include 

about 1,400 square miles of merchantable timberland, 900 square 

miles of woodland, and about 800 square miles of burned area.

In the middle basin, from the lower end of Gore Canyon to about 

Rifle, 30,000 to 35,000 acres will be irrigated under half a dozen small 

projects now contemplated. In the lower basin the Reclamation 

Service has underway the Grand Valley project, to cover an irrigable area of 60,000 to 70,000 acres. Under other schemes, 40,000 to 

50,000 acres more will be irrigated. The Uncompahgre Valley 

project, which diverts water from the Gunnison, has finished structures capable of irrigating about 50,000 acres. The completed 

project will serve about 150,000 acres. 

43924° WSP 280 12 8
114 SURFACE WATER SUPPLY, 1910, PART IX.

Natural storage within the basin is restricted to a few high mountain lakes, of which Grand Lake is the largest. There are, however, 

reservoir sites along the Grand and its tributaries which, if utilized, 

would make possible a development of 1,000,000 horsepower. The 

Kremmling reservoir site is by far the best in the drainage basin. 

It is located near the upper end of Gore Canyon and with a 230-foot 

dam would impound about 2,200,000 acre-feet of water. A standardgage railroad now runs through this site.

Until recently the splendid power resources of this drainage basin 

have remained practically untouched. The estimated available 

power, including that on Dolores and Gunnison rivers, is as follows:

Minimum horsepower...................................... 540, 000

Minimum horsepower, six high months...................... 1, 000, 000

Horsepower from storage, six months' period................ 1, 600, 000

Of this amount less than 40,000 horsepower has so far been developed.

Hot sulphur springs are located along Grand River at two points, 

Hot Sulphur Springs and Glen wood Springs, Colo., and in both 

localities they increase the temperature of the river water, but probably all these springs together add less than 20 second-feet to the 

flow of the river. .

Since 1899 the year of maximum run-off in this basin was 1909. 

The year of minimum run-off was 1902.

NORTH FORK OF GRAND RIVER NEAR GRAND LAKE, COLO.

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

between Grand Lake and Granby, about 12 miles from Granby 

station, on the Denver, Northwestern & Pacific Railway, about 3 

miles southwest of Grand Lake post office, Colo., and about 2 miles 

above Grand Lake outlet, the most important tributary of this fork 

of the Grand, was established July 29, 1904, discontinued September 

30, 1909, and reestablished September 21, 1910. The drainage area 

at this point comprises about 125 square miles.

One large ditch above the station diverts water into the headwaters 

of the Cache la Poudre, in the South Platte basin.

A staff gage is attached to the bridge. Its datum has remained 

unchanged during the maintenance of the station.

Winter records at this station are more satisfactory than at the 

other stations on the headwaters of the Grand, as near-by springs, 

tend to keep the stream at the gaging section more or less open.

Fairly good results have been obtained at this station, though 

low-stage measurements, because of sluggish current, are not entirely 

satisfactory.

GRAND RIVER NEAR GRANBY,' COLO.

This station, which is located at a highway' bridge that crosses 

the river about 4 miles from Granby on the road to Grand Lake, 

was established June 10, 1908. During 191:0 it was maintained in 

cooperation with the State engineer of Colorado.

The station is about 4 miles below the junction of North and 

South forks, about the same distance above the mouth of Fraser 

River, and is above the mouth of Willow Creek. The drainage area 

is -484 square miles.

No important diversions are made on the South Fork or on the 

main stream above the station. Several filings for power development have been made above this station, but additional opportunities for filing no doubt exist. A small power plant is located on a 

tributary of the South Fork.

Measurements of discharge are made from a cable 300 feet downstream from the bridge.

Thick ice covers the river for about four months each year and 

anchor ice also occurs.

The location and datum of the gage have remained unchanged 

during the maintenance of the station.

GRAND RIVER AT SULPHUR SPRINGS, COLO.

This station, which was originally located at the highway bridge 

one-eighth mile below Sulphur Springs and later removed to the new 

highway bridge about 1,000 feet above the old site, was established 

July 27, 1904, discontinued September 30, 1909, and reestablished 

September 23, 1910, in cooperation with the State engineer of Colorado and the United States Forest Service.

Grand River is joined by Eraser River about 10 miles above Sulphur 

Springs and by Williams Fork a few miles below.

A standard chain gage installed near the station was moved to the 

new bridge April 17, 1906, and has been used at the same location 

and datum since the reestablishment of the station. The chain gage 

bears no determined relation to the original gage.

A number of small private ditches divert water for meadow irrigation along the tributaries above the station and along the Grand.

The river freezes across for about four months each year, the ice 

sometimes reaching a depth of 2 feet during the winter months, and 

temporary gages have been maintained in the canyon one-quarter 

mile below the station, where the river is open and where measurements can be made by wading.

GRAND RIVER NEAR KREMMLING, COLO.

This station, which is located at the upper end of Gore Canyon, 

about 3 miles west of Kremmling, near the Kremmling reservoir 

dam site and about 2 miles below the mouth of Blue River, was 

established July 24, 1904, and is maintained in cooperation with the 

State engineer of Colorado.

Between this station and the station at Sulphur Springs, Williams 

Fork and Troublesome and Muddy rivers enter the Grand, and a 

number of private ditches divert water for meadow irrigation for 

both the main stream and its tributaries.
COLiOBADG EIVEB BASIN. 119

On October 18, 1906, a slope gage was established on the opposite 

side of the river from the old chain gage. The zero of the slope gage 

is about-0.70 feet above the chain gage zero. On July 28, 1910, a 

Friez automatic gage was installed by the State engineer, presumably 

at the same datum and at practically the same location as the slope

Discharge measurements are made from a cable a few feet downstream from the gage.

The river is frozen completely across at the station for about 

four months each year; anchor ice also forms in the riffles just below 

the gage.

The channel is scoured out during high stages and silt is deposited 

at low stages. High and medium stage data are good but lowstage data are not so accurate.

COLORADO RIVER BASIN.

GRAND RIVER AT GLENWOOD SPRINGS, COLO.

This station, which is located at Glenwood Springs, about onefourth mile above the mouth of Roaring Fork, was established May 

12, 1899, discontinued July 17, 1899, and reestablished January 7, 

1900. It is now maintained in cooperation with the State engineer 

of Colorado and the Central Colorado Power Co.

The original gage, of the float type, was located at the plant of the 

Glenwood Light & Power Co. about one-fourth mile above the State 

bridge, and was replaced May 10, 1910, by a Friez automatic gage 

installed at the same location and datum.

Discharge measurements are made from a cable underneath the 

State bridge.

A few minor irrigation ditches divert water from the river between 

this station and the station at Kremmling. The Shoshone plant of 

the Central Colorado Power Co., utilizing a head of 170 feet, was 

practically completed in 1908. The tail water from this plant is 

returned to the river above the gaging station. During 1907 and 

1908 the debris from the Shoshone plant was deposited in the river 

bed and the discharge rating curve of the stream was thereby changed. 

Except during this period the channel has been permanent. 

 Even in the most severe weather hot water from the near-by 

springs keeps the water in the river above the freezing point. The 

winter records are, therefore, of special value as they furnish a basis 

for estimating approximately the discharge of the streams at other 

stations in the basin during that period.

Results of observations at this station were trustworthy prior to 

the latter half of 1910, when the new automatic gage gave unsatisfactory results.

NOTE. Daily discharge Jan. 1 to June 11 determined from a fairly well defined discharge rating curve 

by direct application Jan. 1 to Apr. 30, and by the indirect method for shifting channels May 1 to June 

11. Gage heights from June 11 to Dec. 31 are practically useless, as the trough connecting float well with 

the river became clogged, and therefore they have not been published. Discharge May 15,16, and 18 to 21 

and June 12 to Dec. 31, used in computing monthly means, obtained from hydrographs of discharge at 

Kremmling, Palisades, and Roaring Fork stations and current-meter measurements at this station.

COLORADO RIVER BASIN.

GRAND RIVER NEAR PALISADES, COLO.1

This station, which is located at a steel highway bridge 2 miles 

above Palisades, Colo., at a point where the river enters Grand Valley, 

was established April 9, 1902, and during 1910 was maintained in 

cooperation with the United States Reclamation Service.

The station is below all important tributaries except Gunnison and 

Dolores rivers ana is a.bove all the irrigating ditches supplying water 

for irrigation in Grand Valley, except a ditch for one pumping plant 

which diverts about 80 second-feet for irrigation one-fourth mile 

above the gage. The proposed high-line canal of the United States 

Reclamation Service will take its water about 7 miles above Palisades.

The gage has been permanently located at the highway bridge 

above Palisades and no change in datum has been made. The 

original wire gage was replaced by a chain gage April 5, 1904. The 

river usually freezes over a portion of the year, but except for the 

interference of slush ice and an occasional thin ice cover the winter 

records are good.

Conditions for current meter measurements at the gage are poor, 

especially at high water. Beginning September 27, 1905, the measurements were made from a suspension bridge in the town of Palisades. Measurements are now made from the new steel bridge 

opened in the spring of 1909. Conditions at both these bridges are 

about the same. The sections are permanent, but at flood stages the 

velocities are high and the interference of bridge piers 'somewhat 

impairs the accuracy of results. Flood measurements prior to 1906 

made at the upper bridge, where the gage is located, are less reliable 

than those made at the lower bridges.

NOETH INLET TO GI^AND LAKE AT GEAND LAKE, COLO.

Two streams, known as the North and East inlets, flow into Grand 

Lake, North Inlet being the larger. Elevations of the basin in the 

North Inlet range from 8,000 to 11,000 feet above sea level and the 

fall of the stream is very great. The basin comprises 36.5 square 

miles.

The gaging station on the North Inlet, which is located at the foot 

bridge across the stream, 300 yards east of the Grand Lake post 

office and about 100 yards north of the mouth, was established 

August 3, 1905, discontinued September 30, 1909, and reestablished 

September 20, 1910.

No water is diverted above the station, but filings have been made 

on sites for power development.

A staff gage, unchanged in datum during the maintenance of the 

station, is attached to the bridge. The records are fragmentary, as 

the gage has not been read continuously.

The stream is covered with thick ice for about four months, and 

winter gage readings are therefore of little value. The accuracy of 

the records is impaired by the roughness of the stream bed and by the 

effect of ice.

Since the reestablishment of the station gage heights have been 

furnished by the Forest Service.

GRAND LAKE OUTLET AT GRAND LAKE, COLO.

This station, which is located at a footbridge at the west end of 

Grand Lake, about half a mile south of Grand Lake post office, Colo., 

in sec. 6, T. 3 N., R. 75 W., was established July 31, 1904, discontinued September 30, 1909, and reestablished September 20, 1910. 

Granby, about 15 miles distant, on the Denver, Northwestern & 

Pacific Railway, is the nearest railroad point.
COLORADO EIVER BASINV 127

The drainage area at the station is 62 square miles.

A staff gage, unchanged in location or datum, is installed at the 

footbridge.

Discharge measurements have been taken at various sections, 

more usually at a ford one-fourth mile downstream from the footbridge.

Shore ice forms at the station for about four months, but the 

stream does not freeze over because of the higher temperature of the 

water coming down Grand Lake.

During low stages the accuracy of the results is to a considerable 

extent impaired by the rough bottom and sluggish character of the 

stream.

Since the reestablishment of the station gage heights have been 

furnished by the Forest Service.

WILLIAMS FORK NEAR SULPHUR SPRINGS, COLO.

This station, which is located near the mouth of the stream, at the 

wagon bridge on the ranch of F. A. Field, about 9 miles west of Hot 

Sulphur Springs, Colo., was established July 25, 1904. The nearest 

railroad point is Parshall, a station on the Denver, Northwestern & 

Pacific Railway.

The drainage area is about 200 square miles.

The station is below all tributaries. A number of irrigation ditches 

divert water below the station. Some work has been done toward 

the construction of a reservoir and power plant a couple of miles 

downstream from the station.

Springs keep the ice from getting very thick at this station, but 

slush ice occurs frequently throughout the winter. The morning* 

gage readings are usually distorted as the result of ice at the gage, 

but the afternoon readings indicate the open-water stage closely.

No change has been made in the location or in the datum of the 

staff gage at the bridge during the maintenance of the station.

Results are satisfactory. During low stages in the winter the flow 

is constant, being nearly all from springs.

BLUE RIVER BASIN. 

BLUE RIVER AT DILLON, COLO.

Blue River rises among the peaks of the Continental Divide in the 

extreme southeastern part of Summit County, Colo., and flows in a 

general northwesterly direction to its junction with Grand River 

above the point where the latter stream enters Gore Canyon.

This station, which is located at the second bridge on the road past 

the depot from the town to the cemetery, was established October 15, 

1910.

The gage is a vertical rod fastened to the right abutment on the 

downstream side of the bridge.

High-stage measurements are made from the bridge. At ordinary 

and low stages measurements are made by wading just below the 

bridge.

No water is diverted above this station.

Gage heights are furnished by the Forest Service.

The following discharge measurement was made by S. T. Harding:

October 15, 1910: Width, 31 feet; area, 41 square feet; gage height, 1.50 feet; discharge, 41 second-feet.

Daily gage height, in feet, of Blue River at Dillon, Colo., for 1910.

ROARING FORK BASIN. 

ROARING FORK AT GLENWOOD SPRINGS, COLO.

Roaring Fork, one of the largest tributaries of*the Grand, drains 

an area lying chiefly in Pitkin County and reaches to the summit 

of the Continental Divide. Frying Pan and Crystal rivers are its 

most important branches.

This station, which is located on a single-span wooden road bridge 

about four blocks west of Grand Avenue, Glenwood Springs, and 

about 500 feet above the junction of Roaring Fork with Grand 

River, was established April 6, 1906, discontinued September 30, 

1909, and reestablished September 21, 1910.

A number of small irrigation ditches divert water from the stream 

and its tributaries. Three important power plants, located on 

Crystal River, Yule Creek, and Maroon and Castle creeks, develop 

2,100 horsepower. A number of smaller plants are also in operation 

in this basin. The drainage area above this station is 1,450 square 

miles.

A chain gage, unchanged in location or datum, is attached to the 

bridge.

As the stream bed is very rough conditions are unfavorable for 

accurate measurements. The channel is, however, fairly permanent.

Slush and anchor ice are common at this station, but solid ice 

rarely covers the river. At extremely high stages in Grand River 

backwater from that stream may somewhat affect the relation 

between gage height and discharge at this station.

In general the results of observations at this station are satisfactory.

Since the reestablishment of the station gage heights have been 

furnished by the Forest Service.

DIVIDE CREEK BASIN. 

GENERAL FEATURES.

Divide Creek enters Grand River from the south about 6 miles 

below Newcastle, Colo. It is formed by East and West Divide creeks, 

which unite a few miles below the mouth of the stream. The run-off 

in this basin is derived chiefly from melting snows and from rain.

WEST DIVIDE CREEK AT BEARD'S RANCH, NEAR RAVEN CREEK, COLO.

This station, which is located at Beard's ranch, 1^ miles below the 

head gates of the High Line ditch, was established April 28, 1910, and 

replaces the station maintained from July 27 to September 20, 1909, 

at Hostutler's ranch, one-fourth mile below the head gates of the 

ditch.

The drainage area above this station is 82 square miles.

The gage is a vertical rod fastened to an overhanging tree on the 

left bank 100 yards upstream from the ranch house.

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

shift somewhat.

At low and medium stages discharge measurements are made by 

wading at selected sections; at high stages they are made from a foot 

log 50 yards upstream from the gage.

MAMM CREEK BASIN. 

WEST MAMM CREEK NEAR RIFLE, COLO.

Mamm Creek, which enters Grand River from the south about 

4 miles upstream from Rifle, Colo., is formed by the junction of 

West Mamm, East Mamm, and Middle Mamm creeks, all of which 

rise on the north side of Battlement Mesa.

The flow of this stream is supplied by melting snow in the spring 

and by rains. Its channel is usually dry or nearly so during the late 

summer and fall.

The gaging station was established July 26,1909, and discontinued 

September 19, 1910. It was located just south of J. T. Selby's 

ranch house, 9 miles south of Rifle, Colo., about half a mile above 

the mouth of Quakenasp Gulch Creek, and three-fourths of a mile 

above the dam site of a proposed irrigation reservoir.

One ditch of less than 10 second-feet capacity diverts water above 

the station. The waste water from this ditch is returned to the 

creek a few feet above the staff gage.

From November 16, 1909 to March 6, 1910, a 24-inch trapezoidal 

sharp-edge weir, with end contractions, was used to measure the
COLORADO KIVEK BASIN. 141

flow of the stream. This weir is located about 50 feet downstream 

from the gage. Current-meter measurements were made at several 

sections in the vicinity of gage.

Ice exists to some extent for an extended period during the winter 

season. Conditions at this station are not conducive to the most 

accurate results, especially during the higher stages, when gage 

heights show great fluctuations and measurements are difficult to 

make.

GUNNISON RIVER BASIN. 

GENERAL FEATURES.

Gunnison River is formed in Gunnison County, Colo., by East and 

Taylor rivers, two streams that rise among the snow-covered peaks 

and on the slopes of the Continental Divide in the northeastern part 

of the county, descend through narrow mountain valleys, and unite 

about 12 miles above Gunnison. From the junction of these rivers 

the Gunnison flows west and southwest to the point where it enters 

Grand River at Grand Junction, in the central part of Mesa County, 

Colo.

The upper course of the river lies through a broad, mountainous 

valley, but near the mouth of Lake Fork the valley narrows and the 

river enters Black Canyon of the Gunnison, through which it winds 

in a tortuous course for 56 miles between granite walls that rise precipitously 3,000 feet above the water's edge. A short distance below 

the mouth of North Fork, the largest tributary of the river, the canyon 

walls break abruptly, and the stream enters a broad and fertile valley. 

Below Delta the river enters another canyon, with walls averaging 

800 feet in height, and this continues irregularly to Grand Junction, 

only a few tracts of narrow bottom land lying between the channel 

and the canyon walls.

The soil of the lower valleys is chiefly adobe, and the higher mesas 

contain much gravel and sand. Groves of quaking aspen interspersed 

with large, open grazing plots cover broad areas of this plateau region. 

On the top of the Grand Mesa are forests of pine and aspen, and along 

the foothills grow pinon and cedar. In the valleys chico and sagebrush form the principal vegetation, except along the streams, which 

are bordered in places by cottonwood, willow, and undergrowth.

The chief tributaries of the Gunnison are Ohio, Tomichi, Lake Fork, 

and Cimarron creeks, and Smith, North Fork, and Uncompahgre 

rivers, North Fork being the largest. All the tillable lands of the 

North Fork and its tributaries have been brought under cultivation, 

and irrigation is practiced to such an extent that the entire flow is 

needed for existing systems. Ohio, Tomichi, Lake Fork, and Cimarron creeks are perennial streams, but almost their entire volume is
COLORADO RIVER BASIN. 143

diverted for irrigation during the growing season, so that very little 

water reaches the Gunnison except at times of heavy storms or during 

spring floods.

Precipitation records for the Gunnison are meager. Those which 

exist show a range from 9 inches in the plateau region to about 25 

inches in the mountains.

The run-off of the Gunnison drainage basin is conserved to a large 

extent by four national forests, which have a total area of about 5,700 

square miles, of which approximately 3,800 square miles are located 

within the basin. About 65 per cent of this area is in standing timber, the remainder being classified as sagebrush, barren, and burned. 

Investigation of the headwaters of East River and other tributaries 

in Gunnison County several years ago discovered that many of the 

hills had been almost entirely denuded of their timber, a discovery 

to which may be attributed the setting aside of the areas as forests.

Along Gunnison River proper above the mouth of Lake Fork a 

number of ditches divert water for meadow irrigation, and irrigation 

is extensively practiced in the vicinity of Delta. The largest irrigated 

area in the Gunnison drainage basin is the Uncompahgre Valley. (See 

p. 150.)

The country is not adapted for large reservoirs, the meadows having so much fall and the valleys being so narrow that construction 

would be expensive in proportion to reservoir capacity. However, a 

large number of small reservoirs exist on the Gunnison and its tributaries, which can be advantageously utilized for power.

Power plants at present in operation in this basin develop about 

2,200 horsepower, and there are many sites unutilized. The fall 

along some of the streams is heavy, ranging from 50 to 150 feet to the 

mile. Along the Uncompahgre, from its source to the 8,000-foot 

contour, the fall is almost 300 feet to the mile. At the present time 

the waters in this basin are being used for domestic purposes, irrigation, and power. By utilizing all the available storage it would 

theoretically be possible to develop about 200,000 horsepower. 

Along the South canal of the United States Reclamation Service, 

which receives the water from .the Gunnison tunnel and carries it 

into Uncompahgre River, a series of drops will make possible the. 

development of 5,000 to 10,000 horsepower.

Since 1903 the wettest year was 1909 and the driest 1904. "By 

comparison with other drainage basins adjacent to the Gunnison, 

however, it is evident that 1902 was a drier year than 1904.

TAYLOR RIVER AT ALMONT, COLO.

This station, which is located at the wagon bridge at Almont, 100 

yards above the confluence of Taylor and East rivers, in sec. 22, 

T. 51 N\, R. 1 E., New Mexico principal meridian, was established 

July 27, 1910, by the United States Reclamation Service.
144 SURFACE WATER SUPPLY, 1910, PART IX.

The gage is a vertical rod spiked to the downstream* side of the 

center pier.

Discharge measurements are made from downstream side of the 

bridge.

A station was maintained on Taylor River 14 miles above Almont 

from April 17 to November 24, 1905.

GTTNNISON RIVER AT RIVER PORTAL, COLO.i

This station, which is located about 300 feet above the portal of 

the Gunnison tunnel, about 21 miles northeast of Montrose, about 8 

miles below the mouth of Crystal Creek, and above North Fork and 

Uncompahgre River, was established April 7, 1905, replacing the 

station at Cimarron, about 12 miles above.

A number of small ditches divert water for meadow irrigation above 

the station. The largest diversion along the river, and also in Colorado, is the recently completed Gunnison tunnel, with a capacity of 

about 1,300 second-feet, which diverts the water from the Gunnison 

into the Uncompahgre Valley.2

The original staff gage, which was bolted to the cliff on the right 

bank of the river, was dislodged by driftwood on June 4, 1909. 

Prior to this date no change occurred in the location or datum of 

this gage. From June 5 to 19 an old high-water gage, about 100 

feet upstream on the left bank, was read. The datum of this gage 

is 10.08 feet lower than that of the original gage. The readings were 

reduced to the original datum. This auxiliary gage could not be 

used after June 19, as the water surface had fallen too low. On

1 This station was referred to in previous reports as "at east portal of Gunnison tunnel."

2 The Gunnison tunnel and Uncompahgre project are described in the reports of the United States 

Reclamation Service.

146 SURFACE WATER SUPPLY, 1910, PART IX.

August 9, 1909, a new staff gage was installed at the same location 

and datum as the original gage. This gage was broken off by ice 

November 20, 1909, and reestablished at same location and datum 

March 16, 1910.

Discharge measurements were made from a cable a few feet downstream from the original gage site.

Ice covers the river about four months each year, attaining a 

thickness of 1 to 2 feet. No winter records of discharge have been 

obtained.

This station is maintained under the supervision of the United 

States Reclamation Service. Computations of discharge have been 

made by engineers of the United States Geological Survey.

CEMENT CREEK NEAR CRESTED BUTTE, COLO.

This station, which is located 200 feet south of R. Ahrne's ranch 

house, 1J miles above the mouth of the creek, 1J miles northeast 

of Glaciers Landing, a flag station on the Colorado & Southern 

Railway, and about 7 miles southeast of Crested Butte, the nearest 

post office, was established November 23, 1910. The station is 

8,200 feet above sea level.

The gage is a vertical rod nailed to an 8-inch pine tree on the 

right bank.

Discharge measurements are made by wading at various sections, 

except at extreme high water, when they may be made from a foot 

bridge a short-distance above the gage.

Inflow from a warm spring a short distance above the station 

tends to keep the channel open. Opportunity is thus afforded for 

accurate determination of winter run-off.

Gage heights are furnished by the Forest Service.

The following discharge measurement was made by G. H. Russell:

November 23, 1910: Width, 19.5 feet; area, 20 square feet; gage height, 0.36 feet; 

discharge, 17 second-feet.

The following gage heights have been observed:

November 23, 0.4, November 24-26, 0.3, November 27, 0.4, December 1-31, 0.3.

TOMICHI CREEK NEAR GTJWWISOW, COLO.

This station, which is located at a highway bridge about 1J miles 

south of Gunnison and about l\ miles above the mouth of the creek, 

was established November 25, 1910.

A vertical rod gage is spiked to the downstream end of the left 

abutment of the bridge.

Discharge measurements at high stages are made from the bridge, 

which makes an angle with the current; at normal stages measurements are made by wading at various sections.

The stream bed is composed of small rocks and gravel and may 

shift somewhat.

Gage heights are furnished by the Forest Service.

The following discharge measurement was made by G. H. Russell:

November 25, 1910: Width, 34 feet, area, 92 square feet; gage height, 0.63 feet; 

discharge, 106 second-feet.

QUARTZ CREEK AT PITKIH, COLO.

This station, which is located at the second wagon bridge crossing 

the creek on the road from Pitkin to Gunnison, near the Colorado & 

Southern Railway tracks, was established December 12, 1910.

No water is diverted above this station and no tributaries enter 

below.

The gate is a vertical rod fastened to an abutment of the bridge.

Measurements can be made by wading at low stages and from 

the bridge at high stages.

No discharge measurements were made during 1910.

Gage heights are furnished by the Forest Service.

TTNCOMPAHGRE RIVER BASIN.

GENERAL FEATURES.

Uncompahgre River, the principal tributary of the Gunnison from 

the south, rises among the snowy peaks of the highly serrated 

Uncompahgre Mountains and flows a little west of north to its junction with the Gunnison at Delta. The basin embraces a mountainous 

plateau and valley area of 1,130 square miles, oblong in shape, the 

width increasing slightly at the lower end. The mountain area 

occupies only a small part of the basin but contributes the perennial 

waters of the stream. The plateau area is greatest in extent and 

borders the valley on both sides, the larger Uncompahgre Plateau 

lying to the southwest. Escarpments are conspicuous features of 

this plateau. The relief features are terraced mesas flanked by 

buttes and ridges and trenched by deep, narrow canyons.

Uncompahgre Valley proper begins at a point near Eldredge siding, 

on the Denver & Rio Grande Railroad. In addition to the lands 

being irrigated by large private ditches, this valley contains about 

150,000 acres, which are being reclaimed under the Uncompahgre 

project of the United States Reclamation Service. The greater part 

of the water for this* land is diverted from Gunnison River by means 

of the Gunnison tunnel, which has a capacity of 1,300 second-feet. 

The construction of the tunnel was begun in January, 1905, and the 

actual opening through the tunnel was completed July 6, 1909. The 

present water rights consume the normal flow of Uncompahgre River, 

and the Uncompahgre Valley project will divert all the available 

water from Gunnison River during normal stages.

UNCOMPAHGRE RIVER AT AND NEAR PORT CRAWPORD.

A gaging station was established on Uncompahgre River at a highway bridge about half a mile west of Fort Crawford, in sec. 36, T. 48 N., 

R. 9 W., October 2, 1907, and discontinued October 31, 1910. On 

July 2, 1910, a station was established 2 miles below Fort Crawf ord 

on the north line of sec. 23, T. 48 N., R. 9 W., New Mexico principal 

meridian. The upper station was established to replace the station 

nearColona, which was maintained from August 10, 1903, to May 31, 

1906.

The upper station is located just below the mouth of Horsefly 

Creek. A number of large irrigation ditches divert water above the 

station and existing power plants generate about 1,800 horsepower.

The rod gage which was established October 2, 1907, was washed 

out June 21, 1908. A temporary chain gage, the zero of which was 

placed 1.95 feet below the zero of the rod gage, was installed July 7, 

1908. On July 23, 1908, a permanent rod gage was installed, the zero

on the chain gage. During 1909 the chain gage established July 7, 

1908, was read. In the early part of 1910 a new rod gage was established with a datum 3.20 feet lower than that of the chain gage. The 

readings for 1909 were reduced to this datum.

Thick ice forms along the edges of the river during the winter 

months. The channel remains open at the station, but the relation 

between gage height and discharge is at times affected by slush ice. 

The channel scours during high stages and silts during periods of low 

water.

The records derived from the observations at the upper station are 

rather poor.

At the lower station the gage is a vertical rod fastened to the 

upstream side of the single-span wooden highway bridge.

Discharge measurements are made from the bridge.

The record derived from the observations at the lower station is 

very good, as the stream bed at this point is permanent and sufficient 

measurements were made to enable the construction of a-well-defined 

curve for the period from July 11 to October 31.

As the amount of water diverted daily between the upper and the 

lower stations during the period July 11 to October 31 is known, the 

discharge at the upper station for this period can probably be more 

accurately determined by adding the amount diverted to the flow at 

the lower station.

The following tables give the data for the upper and the lower 

stations, the diversions between, and the flow at the upper station as 

computed from the lower station flow plus diversions above.

Both stations have been maintained under the supervision of the 

United States Reclamation Service.

UNCOMPAHGRE RIVER AT MONTROSE, COLO.

This station, which is located at the iron highway bridge just west 

of Montrose, one-quarter mile west of the Denver & Rio Grande 

Railroad, about 2 miles above Happy Canyon Creek and also above 

Cedar and Springs creeks, was established April 22, 1903.

Large irrigation ditches divert water between this station and that 

at Fort Crawford. The normal flow of this river is controlled for 

irrigation by existing water rights above the diversions, although 

opportunities exist for storage and power development. Established 

plants generate about 1,800 horsepower.

The staff gage, unchanged in location or datum during the maintenance of the station, is 20 feet upstream from the bridge.

Thick ice forms along the edges of the river in winter, but the 

channel usually remains open. The relation between gage height 

and discharge is at times affected by slush ice and anchor ice. The 

results obtained are good except for the winter periods and at times 

of extremely low water. The flow at this point will be affected by 

inflow of the South canal of the United States Reclamation Service.

UNCOMPAHGRE RIVER NEAR DELTA, COLO.

This station, which is located on the second highway bridge 2 miles 

south of Delta, Colo., was originally established April 29, 1903, at a 

highway bridge one-fourth mile above the Denver & Rio Grande 

Railroad bridge. On November 17, 1903, it was removed to the railroad bridge one-fourth mile northwest of the depot at Delta. A vertical gage at this bridge was read until April 21, 1904, when an inclined 

gage was installed on the right bank near the bridge. This gage was 

read until November, 1906, when a staff gage was installed at the present site, but observations at this gage were not begun until April 21, 

1907. It was washed out September 6, 1909, and reestablished April 

19, 1910, approximately on the site of the old gage. The plotting of 

the 1910 discharge measurements indicates that the datum of the last 

gage is about 0.2 foot higher than that of the preceding gage. The 

relation between the datum of the last gage and the several earlier 

gages has not been determined, and the datum of the gage used from 

April 22, 1904, to November, 1906, differs from that of the previous 

gage.

The station is near the junction of the Uncompahgre with the Gunnison and is below all tributaries and diversions. At ordinary stages 

the flow of the river at this point is nearly all seepage water from the 

irrigation ditches above. During the irrigating season the ditches 

consume all the normal flow.

The relation between gage height and discharge is probably not 

materially affected by ice, as thick ice does not form except along the 

edges of the stream; slush ice frequently occurs.

Records derived from observations at this station are good except 

for periods of extreme low water.

The station is maintained under the supervision of the United 

States Reclamation Service.

160 SURFACE WATER SUPPLY, 1910, PART IX.

DOLORES RIVER BASIN.

GENERAL FEATURES.

Dolores River rises in the La Plata and San Miguel mountains, 

whose highest peak, Mount Wilson, attains an elevation of over 

14,000 feet above sea level. It flows southwestward about 50 miles, 

then almost due north for nearly 100 miles, then again westward, and 

enters Grand River about 15 miles west of the Colorado-Utah line. 

For the greater part of its course the river flows through deep canyons, and comparatively little irrigation is practiced along the stream 

itself. In the vicinity of Dolores, however, the valley broadens, and 

for about 40 miles has a width of half a mile to a mile. A considerable 

part of this area is cultivated. In Paradox Valley, also, considerable 

land is cultivated, chiefly from small tributaries running into the 

main stream. By far the greater part of the Dolores River water is 

used for irrigation in the San Juan drainage basin, to which it is 

diverted by means of a tunnel and a great cut into the Montezuma 

Valley.

San Miguel River, the most important tributary of the Dolores, 

which drains an area immediately west of the" headwaters of the. 

Uncompahgre River, rises in San Miguel County, Colo., and enters 

the Dolores about 12 miles east of the Colorado-Utah line, at an elevation of about 5,000 feet. In general the stream and its tributaries 

flow northeastward. Considerable land along the San Miguel is 

irrigated.

The mean annual run-off of Dolores River above the mouth of the 

San Miguel is about 400,000 acre-feet, and the San Miguel furnishes 

at least half that amount.

Probably 600 square miles of the Dolores River basin is covered 

with merchantable timber and as much more is woodland. The total 

area of this basin is about 4,500 square miles.

The basin contains several small storage reservoir sites, a few of 

which have been developed, both for power and irrigation.

The river has an average fall of over 20 feet to the mile throughout 

almost its entire course, and a great stretch of the San Miguel has an 

average fall of more than 50 feet to the mile. Several water-power 

plants are in operation along the upper San Miguel and its tributaries, 

the development aggregating nearly 10,000 horsepower, of which 

about 7,500 horsepower is developed at the Ames, Howard Fork, and 

Illium plants of the'Telluride Power Co. One plant on Bridal Veil 

Creek is utilizing a head of 2,000 feet to develop 1,200 horsepower.

DOLORES RIVER AT DOLORES, COLO.

This station, which is located at the wagon bridge about a quarter 

of a mile southwest of Dolores depot and abqut half a mile above the 

original site, was established June 25, 1895, discontinued October 31,
COLORADO RIVER BASIN. 161

1903, and was reestablished August 27, 1910, by the State engineer 

of Colorado, by whom the records are furnished.

A vertical staff gage is bolted to the bridge abutment, and a Bristol 

automatic gage was installed November, 1910. Both gages are 

referred to the same datum. The relation between the new gages and 

the gage at original section has not been determined.

The bed of stream consists of sand, cobbles, and some small bowlders, and is apparently permanent. At high stages the river may 

overflow the left bank.

Low-water measurements are made by wading; high-stage 

measurements are made from the bridge.

The relation between gage height and discharge is somewhat 

affected by ice during the winter months.

SAN MIGTJEL RIVER AT FALL CREEK, COLO.

A gaging station was established on San Miguel River at Fall 

Creek, Colo., by the State engineer August 26, 1910, and was abandoned about a month later in favor of a site near Placerville, where 

the observations would indicate the run-off from the drainage areas 

of Leopard and Fall creeks, as well as that of the San Miguel.

The following discharge measurement was made by Christiansen 

and Ferguson:

August 26, 1910: Width, 30 feet; area, 41 square feet; gage height, 1.00 foot; discharge, 107 second-feet.

SAN MIGTJEL RIVER AT PLACERVILLE, COLO.

This station, which is located at the corduroy bridge three-fourths 

of a mile below Placerville, was established September 13, 1910, by 

the State engineer, by whom the records are furnished.

A vertical staff gage is fastened to the abutment of the bridge.

The channel consists of gravel and some bowlders and is fairly 

permanent, affording a very good measuring section.

Measurements are made from the lower side of the bridge or by 

wading at various sections.

The relation between gage height and discharge is affected by ice 

during the winter.

FREMONT RIVER BASIN.

GENERAL FEATURES.

Fremont River heads in the eastern slopes of the Wasatch Mountains in Sevier County, Utah, one of the sources being Fish Lake. It 

flows in a general southerly direction to Thurber, from which point 

it traverses the central portion of Wayne County in a general easterly 

direction to Hanksville, where it turns southward; it joins Colorado 

River about 8 miles above Hite, Utah. It receives one important 

tributary, Curtis Creek,1 from the north and a number of smaller 

streams, including Tantalus and Lewis creeks, from the south. 

The lower half of its course is through two deep canyons separated 

by a valley. On the upper stretch of the main river is what is 

known as Rabbit Valley. Both Fremont River and Curtis Creek 

are considerably augmented in volume by springs in their canyons, 

but they derive the greater part of their waters from melting snows 

on the plateau.

FREMONT RIVER NEAR THURBER, UTAH.

This station, which is located about 2 miles (by road) south of 

Thurber, Utah, was established May 13, 1909.

Pine Creek enters about 2 miles above the station. This creek 

and springs in the valley just above the station furnish much of the 

low-water flow. Most of the normal low-water flow is diverted above 

and below the station for irrigation.

The staff gage is on the left bank about 2,000 feet above a gristmill. The gage-height records are probably not much affected by 

ice.

Discharge measurements are made from a cable at the gage during 

high stages, and by wading at low stages.

As the bed of the stream shifts somewhat, frequent measurements 

are necessary for reliable estimates of daily and monthly discharge.

MUDDY CREEK NEAR EMERY, UTAH.

Muddy Creek rises in the eastern slopes of the Wasatch Mountains in 

the extreme southern corner of San Pete County, and joins Curtis 

Creek about 8 miles below Emery, Utah. Curtis Creek flows southeasterly across Emery County and enters Fremont River near Hanksville, Utah.

The station, which is located at Jacobsen's ranch, about 7 miles 

above and northwest of the town of Emery, Utah, was originally 

established April 29, 1909.

The station is below all tributaries and above all diversions.

Prior to August 25, 1909, records were obtained by measuring down 

to the water surface from a reference point on a flume in which discharge measurements were made. A staff gage was installed at the 

same location and datum on August 25. During August great variations in discharge were caused by heavy rains which washed out the 

gage and so altered the section that the station had to be reestablished September 18 at a new site several hundred feet upstream. An 

inclined staff gage was installed at a different datum and a cable erected 

from which discharge measurements will be made.

ESCALANTE RIVER BASIN. 

ESCALANTE CREEK NEAR ESCALANTE, UTAH.

Escalante River rises in the southern part of Garfield County, 

Utah, under the walls forming the east face of the Table Cliff Plateau; 

flows first northeast, then east, and finally southeast, and enters the 

Colorado in Kane County about 12 miles above the mouth of the San 

Juan. The river is 90 miles long, and in the lower three-fourths of its
168 SUEFACE WATER SUPPLY, 1910, PART IX.

course sweeps through a narrow canyon whose vertical walls range in 

height from 900 to 1,200 feet, in places filling the whole space from 

wall to wall, in places winding from side to side in a flood plain of sand 

and shifting its position more or less with every freshet.

In the upper part of its course it is joined by several tributaries, all 

of which flow through close canyons.

The gaging station, which is located on Escalante Creek, one of 

the headwaters of Escalante River, at the head of the canyon, about 

2 miles below the town of Escalante, Utah, was established August 

5, 1909. The records show the total amount of water available for 

storage in an excellent reservoir site at this point.

The principal tributaries above are Birch Creek, entering about 6 

miles upstream, and Pine Creek, which enters just above the station. 

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

for irrigation in and near Escalante, the run-off at the station representing only the surplus water.

The first gage used was located about 20 feet below the mouth of 

Pine Creek. It was washed out by a severe flood August 31, whicli 

scoured out the bed of the creek about 3 feet and changed the location 

of the channel. From September 1 to November 12, 1909, records 

were kept of the depth of water at a point near the gage site. On 

November 13, 1909, a new gage was set 35 feet above the old one and 

the observer's readings for the intervening period referred to the new 

datum. The records for this period are only approximate. On 

September 16, 1910, a new gage was established, the datum of which 

is 1 foot lower than that of the old gage.

Estimates of winter discharge are very unreliable. The shifting of 

the stream bed makes accurate interpretation of the result difficult.

SAN JUAN RIVER BASIN. 

GENERAL FEATURES.

San Juan River rises among the snow masses that crown the high 

peaks of the San Juan Mountains in southwestern Colorado, flows 

southwestward into New Mexico, then swings to the west and northwest, passing from San Juan County, N. Mex., across the extreme 

southwestern corner of Colorado into San Juan County, Utah, in the 

southwestern part of which it unites with the Colorado.

For the first 75 miles of its course the San Juan is a typical mountain 

stream, but at Canyon Largo, N. Mex., where it turns westward, its 

character changes, and it occupies a broad, winding, sandy channel 

in an arid valley, bordered on each side by terraced mesas. Below 

the mouth of Mancos River the valley narrows, and the river bottom 

is bounded by abrupt bluffs, broken and cut by dry water channels, 

and merging farther on into the walls of a deep, narrow, box canyon, 

in which the river flows to its end.

The headwater areas are protected by fine forests of spruce and 

yellow pine and at lower elevations large areas of aspen. The lower 

basin is practically barren except for an extensive growth of sagebrush, scattered cedars, pifions, and range grasses.

The principal tributaries of the San Juan are Navajo, Piedra, Pine 

(Los Pinos), Florida, Animas, and La Plata rivers, the Anitnas being 

the most important.

Animas River rises in the region above Silverton, and drains portions of the Needle and La Plata mountains, the former being the 

most rugged of the Rocky Mountain ranges. The river flows southward to the Colorado-New Mexico line and thence southwestward to 

the point where it joins the San Juan at Farmington, N. Mex.
COLORADO RIVER BASIN. 171

Most of the region above Durango is well timbered with pine, 

spruce, and aspen, but large areas consist of naked granite peaks. 

Immediately above and below Durango the valley broadens and is 

bordered by mesas and bluffs cut by narrow canyons and covered 

with sagebrush and scattered pines and pinons; along the stream 

channels cottonwoods predominate. The rocks of this region are 

chiefly of sedimentary origin. The soils of the lower valleys consist 

of sandy loam and are very fertile.

La Plata Eiver rises in the La Plata Mountains, about 25 miles 

northwest of Durango, Colo., and flows southward to its point of 

junction with the San Juan. Its drainage basin is a narrow strip 

parallel to and adjoining the Animas basin. The upper portion of 

the basin is a well-watered and forest-clad mountain region which 

merges southward into an arid mesa, plateau, and canyon coumtry. 

La Plata Valley proper is a narrow, shallow depression from Hesperus 

down, bounded on both sides by high, broken table-lands and deeply 

eroded mountains. The lower mountain slopes are covered with 

pinon, scrub oak, and cedar; the lower valleys support heavy growths 

of sagebrush and chico; the upper mountain slopes were at one time 

heavily timbered with spruce and yellow and white pine, but these 

forests have been largely removed by lumbermen.

The other tributaries of the San Juan need not here be described. 

Those mentioned are perennial streams, but much of their water is 

diverted for irrigation and never reaches the main river. In addition 

to the perennial streams are many intermittent creeks throughout 

New Mexico which contribute large volumes of water during heavy 

storms.

The altitudes in the San Juan basin range from over 13,000 feet in 

the highest mountains to between 6,000 and 7,000 feet at the Colorado-New Mexico line. The San Juan at the mouth of the Animas 

has an elevation of about 5,300 feet; at its junction with Colorado 

River the elevation is about 3,500 feet.

Most of the timbered land in the San Juan drainage basin is included in the San Juan National Forest, which contains nearly 2,000 

square miles of merchantable timber, 100 square miles of woodland, 

300 square miles of sagebrush, and 200 square miles of barren and 

burnt area.

In a small area in the high mountains the annual precipitation 

exceeds 25 inches, and over a considerable area the average exceeds 

20 inches; but for the remainder of the area the average in Colorado 

seems to be about 15 inches, that in New Mexico about 10 inches, 

and in Utah about 15 inches.

Above an altitude of 7,500 feet the winters are severe and snowfalls are heavy; below an elevation of 6,000 feet the winters are comparatively open and mild. The upper mountain streams flow under a
172 SURFACE WATER SUPPLY, 1910, PART IX.

thick ice cover, but in the more open country, in the vicinity of Aztec, 

it is rather unusual for the rivers to freeze over entirely, though much 

ice forms along the edges, and slush ice is often seen.

Much land along the valleys of San Juan, Animas,Pine (Los Pinos), 

Florida, and La Plata rivers and the smaller tributaries in Colorado 

is now under cultivation, and also a few thousand acres of valley land 

in New Mexico. Up to this time irrigation has largely been confined 

to the bottom land. The greatest opportunities for future development are in San Juan County, N. Mex., where exceptionally large 

areas, aggregating probably a million acres of fertile lands, are excellently adapted to irrigation. The rivers there are bordered by broad 

mesas and benches, sloping back for miles in many places and easily 

reached by irrigation canals, and the water supply is ample.

Numerous small lakes, high up in the mountains, tend to equalize 

the flow of some of the tributaries, and many large and small storage 

reservoir sites are available. Among others may be mentioned the 

Turley reservoir site, on San Juan River below the mouth of the Pine 

(Los Pinos), which has a storage capacity of about one and a half 

million acre-feet.

Excellent opportunities for power development are presented. 

Theoretically, with proper storage, it will be possible to develop nearly 

300,000 horsepower. Falls of 100 to 300 feet per mile are common 

on the upper reaches of the stream. The San Juan has an average 

fall of about 13 feet to the mile from the mouth of the Piedra to the 

mouth of the Mancos, a distance of about 115 miles, while the fall 

above the mouth of the Piedra is very much greater. The Animas 

has a fall of over 70 feet to the mile from Silverton to Durango, a 

distance of about 40 miles, and from Durango to its mouth the average fall is over 20 feet to the mile. Present developments are practically limited to two power plants on Animas Eiver, of 6,000 and 

1,000 horsepower.

The largest deposits of lignite and bituminous and coking coal in 

the West are in this drainage area.

SAN JUAN RIVER AT ARBOLES, COLO.

This station, which is located about 1,000 feet west of Arboles station, was established August 21, 1910, by the State engineer of Colorado, by whom the records are furnished.

An inclined staff gage is bolted to a high rocky bank on right side 

of stream.

Measurements are made from car and cable during high water, and 

by wading at various sections during low water.

The bed of the stream consists of mud, gravel, and small bowlders, 

and shifts somewhat, but the measuring section is fair.

Relation between gage height and discharge is slightly affected by 

ice during the winter months.
COLORADO BIVEB BASIN. 173

A station was maintained at this point from June 19, 1895, to 

September 30, 1899, by the United States Geological Survey, but 

the relation between the datum of the present gage and that of the 

original gage has not been determined.

SAN JUAN RIVER AT BLANCO, N. MEX.

This station, which was located at a new suspension bridge crossing the San Juan at Blanco, about 4 miles below Turley post office, 

16 miles southeast of the Denver & Rio Grande Railroad at Aztec, 

N. Mex., and about half a mile above the mouth of Canyon Largo, 

which carries large quantities of water only during floods, was established December 9, 1908, to take the place of the station at Turley 

(abandoned Nov. 30, 1908), and was discontinued October 31, 1910.

The suspension bridge and chain gage were washed out by a flood 

on September 6, 1909, and on September 29, 1909, a temporary staff 

gage was established about 30 feet upstream from site of the bridge 

and at a new datum. Discharge measurements after September 6, 

1909, were taken at the suspension bridge at Bloomfield, about 11 

miles downstream, where a wire gage was installed on September 28, 

1909.

The flow of the river at Blanco and Bloomfield should be the same, 

except for the inflow of Canyon Largo.

Daily gage height, in feet, of San Juan River at Blanco, N. Mex., for 1910.

SAN JUAN RIVER NEAR BLOOMFIELD, N« MEX.

This station, which is located at the suspension bridge about 1^ 

miles below Bloomfield and about 11 miles below the station at 

Blanco, where bridge was destroyed by the flood of September 6> 

1909, was established September 28, 1909.

A wire gage was installed, but records were very fragmentary 

until a Friez automatic gage, for a 10-foot stage, installed February 

11,1910, on a 16-inch pile on the right bank just above the suspension 

bridge, was put in operation April 3, 1910. No gage heights were 

observed during 1909.

Discharge measurements are made from the downstream side of 

the bridge.

PIEDRA RIVER AT ARBOLES, COLO.

This station, which is located about one-third mile west of Arboles 

station, Colo., was established August 21, 1910, by the State engineer 

of Colorado, by whom the records are furnished. A station was 

maintained at this point from June 19, 1895, to September 30, 1899, 

by the United States Geological Survey, but the relation between the 

datum of the original gage and that of the present gage has not been 

determined.

A standard chain gage is attached to lower side of railway bridge, 

and a vertical staff gage is fastened to the old cofferdam at the bridge 

abutment. Both gages are at the same datum.

The bed of the stream is composed of mud and gravel and is liable 

to shift during floods. The channel is fairly straight, and the section 

below the bridge affords fair conditions for measurements.

High-water stage measurements are made from the railroad bridge; 

low-stage measurements are made by wading below bridge.

The relation between gage height and discharge is slightly affected 

by ice during the winter.

LOS PINOS KIVEK NEAR IGNACIO, COLO.

This station, which is located at the steel wagon bridge at the 

Ignacio Indian agency, about 2 miles above Ignacio, Colo., was 

established August 31, 1910, by the State engineer of Colorado, by 

whom the records are furnished. The station maintained during 

1899 and 1900 by the United States Geological Survey was probably 

a short distance below the present site. The old bridge to which 

gage was spiked has been washed out. The relation between the 

datum of the old gage and that of the present gage has not been 

determined.

A standard chain gage is attached to the bridge and an auxiliary 

slope gage is fastened to the left bank about 500 feet below the bridge. 

Both gages are referred to the same datum.

The bed is composed of mud, sand, and bowlders, and is somewhat 

shifting. At high stages the river overflows its banks. The measuring section at bridge is only fair.

High-water measurements are made from the bridge. Low-water 

measurements, however, are made by wading at various sections.

The relation between gage height and discharge is only slightly 

affected by ice during the winter months.

ANIMAS RIVER AT DURANGO, COLO.

This station, which is located on the Rio Grande Southern Railroad bridge at Durango, Colo., was established August 22, 1910, by 

the State engineer of Colorado, by whom the records are furnished. 

From June 20, 1895, to December 31, 1905, a station was maintained 

by the United States Geological Survey at the wagon bridge 200 feet 

above the present site. The relation between the original and the 

present gages has not been determined. Lightner Creek enters the 

Animas between the two localities. ^
COLORADO BTVER BASIN. 181

A standard chain gage is fastened to the bridge and a Bristol 

automatic gage was installed November 3, 1910, with datum the 

same as that of the chain gage. The automatic gage was removed 

November 27, 1910, because of some necessary construction work on 

the bridge and was replaced February 9, 1911.

The bed of the stream consists of sand, gravel, and bowlders, and 

shifts somewhat. Both banks are subject to overflow. The measuring section at the bridge is only fair.

Low-stage measurements are made by wading; high-stage measurements are made from the bridge.

The relation between gage height and discharge is affected by ice 

during the winter months.

ANIMAS KIVEK AT AZTEO, N. MEX.

This station, which is located about one-third mile west of Aztec, 

N. Mex., on the main wagon road to Farmington and La Plata, was 

originally established June 21, 1904, at the wooden truss highway 

bridge about three-eighths of a mile west of Aztec, was discontinued 

December 14, 1904, and reestablished at the same location June 8, 

1907. On September 13, 1908, it was moved to a new suspension 

bridge about half a mile above the old bridge, which was torn down 

on completion of the new bridge. The station, although 20 miles 

above the mouth of the river, is below all important tributaries.
182 SURFACE WATER SUPPLY, 1910, PART IX.

The drainage area comprises about 1,300 square miles.

Between Durango and Aztec many large ditches divert water for 

irrigation, and the discharge at the station does not represent the 

total run-off of the stream. Notwithstanding the numerous existing 

water rights, an ample supply of water is available for future development.

No change in the staff gage or gage datum was made during the 

maintenance of the station at the old site. Beginning September 13, 

1908, an inclined staff gage was read, installed a few feet downstream 

from the suspension bridge at an arbitrary datum.

Ice forms to a considerable depth along the edges during the greater 

part of the winter, but the river seldom freezes across. Slush ice 

frequently occurs during the winter months.

FLORIDA RIVER NEAR DURANGO, COLO.

This station, which is located at the wagon bridge at Cash ranch, 

about 7J miles from Durango, was established September 18, 1910, 

by the State engineer of Colorado, by whom the records are furnished. 

From May 19 to July 31,1899, and from April 1, 1901, to October 

31, 1903, the United States Geological Survey maintained a station
184 SURFACE WATER SUPPLY, 1910, PART IX.

on the Florida near Durango. The present station is believed to be 

at the original site, but the relation between the gages has not been 

determined.

A vertical staff gage is bolted to the abutment of the bridge.

The bed of the stream is composed of large and small bowlders, 

sand, and mud and probably shifts but slightly. The measuring 

section at the bridge is only fair.

Discharge measurements are made from the bridge at high water.

The relation between gage height and discharge is affected by ice 

during the winter months.

LA PLATA KIVEK AT HESPERUS, COLO.

This station, which is located at the Rio Grande Southern Railroad trestle at Hesperus, Colo., was established August 24, 1910, by 

the State engineer of Colorado, by whom the records are furnished. 

From June 14, 1904, to August 18, 1906, the United States Geological Survey maintained a station about 100 feet above the present site. 

No water is diverted and no tributaries enter between the two localities. The relation between the gages used has not been determined.

A vertical staff gage is bolted to one of the trestle bents.

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

shifts. Both banks are subject to overflow. The measuring section 

is fair.

Measurements are made by wading.

The relation between gage and discharge is somewhat affected by 

ice during the winter months.

LA PLATA RIVER AT LA PLATA, N. MEX.

This station, which is located at a wooden, single-span highway 

bridge, about 16 miles northwest of Aztec, N. Mex., and 1 mile south 

of La Plata post office, in sec. 3, T. 31 N., R. 13 W., New Mexico 

principal meridian, was established May 25, 1905. This station is 

below all tributaries and is about 15 miles above the mouth of the 

river. The drainage area is about 340 square miles.

Nearly all the normal flow of this stream is diverted for irrigation 

above the station, and there are a few small diversions below.
COLORADO KIVEE BASIN. 187

On December 9, 1908, a chain gage was installed on the bridge 

and is read in place of the rod gage, as the latter does not record 

low stages. The datum remained unchanged.

Thin ice frequently forms across the stream during the winter 

period, thick ice forms along the edges, and slush ice at times interferes with winter measurements.

Because of shifting conditions of channel and the uncertainty of 

some of the gage heights, the results obtained at this station are not 

good.

WEST MANCOS RIVER NEAR MANCOS, COLO.

This station, which is located at Crane's ranch, about 4 miles above 

the town of Mancos, Colo., was established September 16, 1910, by the 

State engineer of Colorado, by whom the records are furnished.

A vertical staff gage is attached to a tree on right bank.

The be.d of the stream is composed of gravel and small bowlders. 

The section is fair.

All measurements are made by wading.

The relation between gage height and discharge is somewhat 

affected by ice during the winter.

190 SURFACE WATER SUPPLY, 1910, PART IX.

VIRGIN RIVER BASIN. 

GENERAL FEATURES.1

Virgin River rises in the Colob Plateau, in the southwestern part 

of Utah, at an altitude ranging from 8,000 to 10,000 feet above sea 

level, flows in a general southerly course across the southwestern corner of Arizona into Nevada, where it turns and flows southward to its 

junction with the Colorado at Rioville, just above Boulder Canyon. 

The smaller creeks that drain the eastern portion of the plateau unite 

after descending to an altitude of 5,500 feet above the sea and form 

what is called Parunuweap Fork of the Virgin. At and below the 

junction of these creeks the canyon valley in which they flow widens 

into what is known as Long Valley. Below Long Valley the East 

Fork enters Parunuweap Canyon and is simply a series of cascades 

for 15 miles, descending in this distance from 5,000 to 3,500 feet above 

sea level. Emerging from this canyon it enters the valley of the 

Virgin. This valley is 44 miles long. Its upper portion is only an 

enlargement of the canyon; its lower portion is a broader valley, 

much broken by low basalt-covered mesas and sharp ridges of tilted 

sedimentary rocks. In the upper part of the valley the river receives 

several tributaries, the principal ones being Little Zion, North Fork, 

La Verkin, and Ashe creeks. Midway of the valley two streams enter 

from the Pine Valley Mountains, and near the foot Santa Clara River 

joins the Virgin, the united streams leaving the valley by a deep 

canyon cut through the Beaver Dam Mountains. The valley of the 

Virgin is at a lower altitude and has a warmer climate than any other 

portion of Utah. The soil of the irrigable lands is usually good, and 

wherever irrigation can be practiced it produces abundant crops.

VIRGIN RIVER AT VIRGIN, UTAH.

This station, which is located about half a mile east of and above 

the town of Virgin, Utah, about 1,000 feet below the mouth of North 

Creek and about 8 miles above Ashe and La Verkin creeks, was 

established April 18, 1909.

There are no diversions of any importance above the station.

The first gage was used until August 7, when the section was 

changed by a flood which caused the water to leave the gage. On 

August 31 the gage, cable, and bench marks were washed out and the 

section materially altered. On October 13 a new gage was installed 

at a different datum. Owing to the marked change in the channel, 

there can be no determined relation between the old and new gages.

i Abstracted from report on the lands of the arid region of the United States, with a more detailed account 

of the lands of Utah, by J. W. Powell, 1878: Chapter 9, Irrigable lands of that portion of Utah drained by 

the Colorado River and its tributaries, by A. H. Thompson, pp. 151-163.
COLORADO EIVER BASIN. 191

The accuracy of the records is unaffected by ice or by artificial 

control above or below the station.

SANTA CLARA RIVER NEAR CENTRAL, UTAH.

This station, which is located about 1^ miles southeast of Central, 

Utah, the nearest post office, and about 6 miles west from the settlement of Pine Valley, Utah, about one-fourth mile from R. H. Hunt's 

ranch house, in a small valley known as Eightmile Flat, was established April 21, 1909. The records show the total amount of water 

available for storage in the Pine Valley reservoir site, a few miles 

above the station.
COLORADO EIVEE BASIN. 193

The station is below all important tributaries except Mountain 

Meadows Creek, which enters about 10 miles below. A small canal, 

whose maximum capacity is about 3.5 second-feet, takes out water 

a short distance above the station.

The gage was destroyed by a flood on January 1, 1910. On 

January 20, 1910, a new gage was established at the same location 

but with its datum 0.45 foot higher.

The bed of the stream is somewhat shifting, but fairly accurate 

results have been obtained.

Discharge measurements are made from the gaging bridge.

The relation between gage height and discharge is not affected 

by ice.

SANTA CLARA RIVER NEAR ST. GEORGE, UTAH.

This station, which is located about 3 miles southwest of St. George, 

Utah, and about 3 miles above the mouth of the river, was originally 

established April 16, 1909.

The station is below all tributaries and diversions except two canals 

which head near the mouth of the river.

The original gage which was located about 1 mile below the present 

location was destroyed by flood about January 1, 1910. The present
COLORADO RIVER BASIN". 195

gage, which was set January 21, 1910, is located on the right bank 

below the cable from which discharge measurements are made. »

The relation between gage height arid discharge is not affected by 

ice, but the bed of the stream shifts to a considerable extent. A fair 

record of run-off has, however, been obtained.

MUDDY EIVJEE AT MOAPA, NET.

This station, which is located just below the Narrows about 7 

miles from Moapa, was originally established January 1, 1904, near 

the crossing of the San Pedro, Los Angeles & Salt Lake Railroad, 

about 6 miles downstream from Moapa, Nev., and above the Narrows. 

It was removed to the present site, 1J miles below the old station, 

January 1, 1909.

Discharge measurements are made in a flume, which carries the 

entire flow of the river except during floods produced by cloudbursts.

BILL WILLIAMS RIVER NEAR SWANSEA, ARIZ.

Bill Williams River rises in the St. Cloud Mountains, in the western 

part of Yavapai County, Ariz., and flows westward to its junction 

with the Colorado at Aubrey Landing.

The station, which is located at a narrow place in the canyon, 

about 1 mile below the Planet mine, 28 miles north of Bouse, and 

about 9 miles northwest of Swansea, the nearest post office, was 

established September 26, 1910.
COLORADO RIVER BASIN. 199

No water is diverted above the station, but water is pumped from 

wells for irrigation on several ranches along the river.

The staff gage is in three sections. The low-water section is fastened to a cottonwood tree on the right bank; the remainder of the 

gage is bolted to the rocks on the left bank.

The channel is straight for several hundred feet above and below 

the station. At the gage the canyon is narrow and the banks are 

high and rocky. The bed of the stream is composed of sand, which 

is constantly shifting.

Discharge measurements at low water are made by wading near 

the "gage. High-stage measurements will be made by means of car 

and cable not. yet installed.

GILA RIVER BASIN. 

GENERAL FEATURES.

Gila River rises in southwestern New Mexico, near the Arizona 

line, and flows southwestward through Arizona to its confluence with 

Colorado River at Yuma. Its total length, exclusive of the many 

windings, is fully 500 miles. The principal tributaries of the Gila 

are San Pedro and Santa Cruz rivers from the south and Salt, Agua 

Fria, and Hassayampa rivers from the north.

The floods of the upper Gila and its tributaries are commonly 

short and violent, highest water occurring during the months of Janu-
200 SURFACE WATER SUPPLY, 1910, PART IX.

ary and February. A period of high water occurs also during the 

late summer or early fall. During freshets the river may rise 8 to 10 

feet above the normal stage and increase in width from 300 feet to 

a mile and a half. It is sometimes impassable for weeks and has the 

appearance of a sea of muddy water. The season of low water 

occurs in June and July, the river bed then being dry in places. 

Elevations in this basin range from 8,000 feet at the headwaters to 

140 feet at Yuma. At Florence, 180 miles below the point at which 

it enters Arizona, it is about 1,500 feet above sea level.

Good storage sites exist at several places along San Francisco and 

Gila rivers, among which may be mentioned the reservoir site on the 

San Francisco near Alma and that on the Gila near Redrock, N. Mex.

Because of the torrential character of the Gila, waterpower development is not feasible except where stored, water is used.

The drainage basin of the Gila includes 7,000 square miles of 

merchantable timberland, 11,000 square miles of woodland, of 

which the San Francisco basin has 1,000 square miles of timberland, 

45,000 square miles of land upon which there is no timber, 1,300 

square miles of scattered timber, and 300 square miles of open land.

The average annual precipitation over the greater part of the 

contributary drainage area of Gila and San Francisco rivers in New 

Mexico is between 10 and 15 inches, and in the high mountains of the 

headwater region it rises above 20 inches. The winters are mild 

except in the mountainous sections, and very little ice forms on the 

rivers.

GILA EIVEE NEAR REDROCK, N. MEX.

This station, which is located in Middle Box Canyon, about oneeighth mile upstream from the mouth and about 2 miles east of Redrock post office, N. Mex., was originally established at the mouth of 

the canyon May 14, 1908. It was moved to its present site July 16, 

1909. The nearest railroad points are Silver City, about 36 miles 

east of Redrock, and Lordsburg, about 30 miles south.

Mancos River, an intermittent stream, the first large tributary 

upstream from the station, joins the Gila about 12 miles above. A 

number* of large washes come into the river above and below the 

station, and at flood times carry a large amount of water. The 

drainage area at the station is about 3,500 square miles. A number 

of large irrigation ditches divert water above the station.

The gage installed May 14, 1908, was bolted to a rock bluff on the 

left bank, a few feet above the mouth of the canyon. This gage was 

abandoned July 16, 1909, when a Friez automatic gage was installed 

on the left bank about one-eighth mile upstream and at a different 

datum. The bed of the stream is composed of sand, which is con-

tinually shifting, and measurements by wading are rendered more or 

less difficult and of uncertain accuracy by quicksand.

Except for fringfe ice along the edges of the stream, the relation 

between gage height and discharge is not affected by ice.

The accuracy of the records derived from observations at this 

station is impaired by the adverse natural conditions.

GILA RIVER NEAR GUTHRIE, ARIZ.

This station, which is located above the Arizona & New Mexico 

Railway bridge (see PL III, B, p. 34) at Guthrie, in sec. 3, T. 6 S.r 

R. 30 E., Gila and Sait River base and meridian, was established 

November 6; 1910.
COLOEADO RIVER BASIN. 203

No important tributaries enter for several miles above the station. 

San Francisco River adjoins Gila River 8 miles below. Approximately 7,000 acres are irrigated above Guthrie. Water is also diverted 

for irrigation below the station. Two reservoir sites in the vicinity 

of the station have been investigated one at Guthrie and the other 

near the mouth of San Francisco River.

The gage is an inclined staff bolted to the conglomerate bluff on 

the right bank about 500 feet above the railroad bridge.

The channel is straight for some distance above and below the 

station. The right bank is high and rocky; the left bank is lower, 

is covered with brush, and is subject to overflow at extreme high 

water. The bed of the stream is composed of shifting sand and silt.

High-stage measurements are made from a car and cable 50 feet 

below the gage. At lower stages measurements are made by wading 

above the gage, as the current at the cable section is very sluggish.

GILA RIVER AT SAN CARLOS, ARIZ.

This station, which is located at the Arizona & Eastern Railroad 

bridge, about 1 mile east of San Carlos on the San Carlos Indian 

Reservation, was established August 17, 1910. From 1899 to 1905 

a gaging station was maintained on Gila River at San Carlos, about 

1 mile below the present station.

San Carlos River enters from the north about one-half mile below 

the station. No other important tributaries enter within several 

miles above or below San Carlos.
204 SURFACE WATER SUPPLY, 1910, PART IX.

The original gage was a vertical staff fastened to the west pier 

of the railroad bridge. On September 7, 1910, a gage, with independent datum, was installed at the old railroad trestle about 200 

yards below the bridge. A curve of relation was determined for 

these gages, and all gage heights for 1910 are referred to the datum 

of the new gage.

The channel has a slight curve above the station, but is straight 

for 1,500 feet below. Both banks are high and not subject to overflow. The bed of the stream is wide and composed of shifting 

sand.

Discharge measurements are made from the railroad bridge, 

except at low water, when they may be made by wading.

NOTE. All gage heights refer to new gage installed on bent of old railroad trestle Sept. 7, 1910, at an 

arbitrary datum. All gage heights prior to this date have been reduced to this datum by a relative 

curve constructed from simultaneous readings of the gage at the railroad bridge and the new gage.
COLORADO IMVER BASIN. 205

FRANCISCO RIVER BASIN. 

GENERAL FEATURES.

San Francisco River rises in the southwestern part of Socorro 

County, N. Mex., and flows southwestward into Graham County, 

Ariz., where it unites with the Gila. The basin comprises about 

2,600 square miles, of which 1,800 square miles are in New Mexico 

and 800 in Arizona. The area drained in New Mexico is high and 

mountainous, the principal ranges being the San Francisco and Tularosa and the western slope of the Mogollon, with peaks ranging from 

8,000 to 10,000 feet above sea level. The average fall of the stream 

is 35 to 40 feet to the mile. The side slopes of the valley descend 

even more steeply and the valleys below, which range in length from 

2 to 3 miles and average about a quarter of a mile in width, are of 

the nature of mesa lands, the leveler portions being 30 to 100 feet 

below the bed of the river. The principal tributaries of the San 

Francisco are Blue and Tularosa rivers. The waters of the San Francisco and its tributaries are used to some extent for mining, and a few 

small ditches take water for irrigation on the bottom lands.

SAN FRANCISCO RIVER AT ALMA, N. MEX.

This station, which is located about half a mile southeast of Alma, 

N. Mex., a short distance below the mouth of Mineral Creek, about 

5 miles above the mouth of Whitewater Creek, and 85 miles northwest of Silver City, the most accessible railway point, was established 

October 18, 1904, by the United States Reclamation Service, discontinued December 31, 1907, and reestablished by the United States 

Geological Survey January 1, 1909.

A few small ditches take water out above the station for the irrigation of the bottom lands.

The rod gage established in 1909 differs in location and datum 

from the previous gage. It was washed out September 6, 1909, and 

replaced October 10, 1909, by another slope gage 100 feet upstream 

but at the same datum. In the intervals between regular gages, 

observations were made on a temporary gage installed by the observer 

and later reduced to the datum of the new gage.

High-water measurements have been made from a cable 300 feet 

upstream from the location of the last gage. (See PL IV, A.) The 

flow of the stream is very little affected by ice, though thin ice sometimes forms on the edges.

As the channel of the stream is composed of materials that shift, 

it is necessary to make frequent discharge measurements in order to 

obtain good results.

SAN FRANCISCO RIVER AT CLIFTON, ARIZ.

This station, which is located at the highway bridge at Clifton (see 

PL IV, B), in sec. 19, T 4 S., R. 30 E, Gila and Salt River base and 

meridian, about 5 miles above the mouth of the river and below all 

important tributaries, was established October 24, 1910.

Water is diverted for irrigation by a small ditch If miles above 

the bridge. At the dam of the Arizona Copper Co., 1| miles above

208 SURFACE WATEK SUPPLY, 1910, PAUT IX.

Clifton, about 14 second-feet is diverted for power development, but 

the water used at the power plant is returned to the river above the 

station.

The gage is a vertical staff fastened to the board retaining wall 

just above the bridge.

The bed is sandy and somewhat shifting. The banks are high and 

not likely to be overflowed. At very low stages there are two channels at the bridge.

High-water measurements are made from the highway bridge. At 

medium and low stages measurements may be made either from the 

footbridge one-half mile below the gage or from the footbridge onefourth mile above. When made at the upper footbridge the discharge 

of the canal must be added to that of the river.

SAN CAKLOS EIVEE BASIN. 

SAN CARLOS RIVER AT SAN CARLOS, ARIZ.

San Carlos River rises in the mountainous section of the San Carlos 

Indian Reservation and takes a general southwesterly course to its 

junction with the Gila at San Carlos. It is an intermittent stream 

and delivers water to the Gila only at times of flood.

The gaging station, which is located at the Arizona & Eastern 

Railway bridge, near the mouth of the river, half a mile east of San 

Carlos, was established August 17, 1910.

The gage is a vertical staff fastened to the west pile of the bridge.

The bed of the stream is composed of shifting sand and silt. The 

left bank is high and rocky. The right bank is low and subject to 

overflow. At the bridge from which discharge measurements are 

made the stream is confined by earth embankments.

SAN PEDRO RIVER BASIN. 

SAN PEDRO RIVER NEAR LEWIS SPRINGS, ARIZ.

San Pedro River rises in the northern part of the Mexican State of 

Sonora, flows northward more than 100 miles, and joins the Gila a few 

miles below the town of Dudleyville, 45 miles above Florence, Ariz. 

Rising in a region of very light snowfall, the river derives the greater 

part of its water from the frequent showers of the rainy season. It 

flows through a sandy bed between high, steep banks, and during the 

dry season it shrinks to an insignificant stream of clear water, which 

rises and sinks into the sand with the varying depths of the bedrock. 

The basin is long and narrow and is bordered by mountains that rise 

6,000 feet above sea level.

The gaging station, which is located half a mile below Charleston 

station on the El Paso & Southwestern Railroad, in sec. 2, T. 21 S., 

R. 21 E., Gila and Salt River base and meridian, and about 5 miles 

below Lewis Springs, was originally established about half a mile 

west of Charleston, 6 miles above Fairbank, on January 27, 1904. 

The station was discontinued August 31, 1906, and reestablished 

at the present site October 18, 1910.

The records derived from observations at this station show the 

amount of water available for storage at the Charleston reservoir site, 

which has been surveyed by the United States Reclamation Service. 

The low-water flow of the San Pedro is not sufficient to irrigate the 

lands now under cultivation.

The gage is an inclined staff on the right bank at the proposed dam 

site.

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

bed of the stream is composed of sand and is shifting.

SANTA CRUZ RIVER BASIN. 

GENERAL FEATURES.

Santa Cruz River rises in the northern part of the Mexican State of 

Sonora; west of the head of San Pedro River, and flows northward 

into Arizona. In its upper part the stream flows in a region of rocky 

canyons and narrow valleys and carries an ample water supply. The 

waters of the lower portion are finally lost in the sands not far from 

Tucson. Elevations in the headwater region range from 4,000 to 

5,000 feet above sea level.

SANTA CRUZ RIVER NEAR NOGALES, ARIZ.

This station, which is located just below the dam site on Yerba 

Buena ranch, about 7 miles northeast of Nogales, was established 

March 22, 1907.

Nearly the entire low-water flow of the Santa Cruz is diverted for 

irrigation above the station. A small ditch takes out water just 

above the gage.

The gage is an inclined staff, in two sections, fastened to a large 

cottonwood tree on the right bank.
COLORADO RIVER BASIN. 213

The channel is straight for some distance above and below the 

station. Both banks are of medium height and not likely to be 

overflowed. At low water the conditions are very unsatisfactory, 

as the bed is shifting sand.

Discharge measurements at medium and high stages are made from 

a cable 100 feet below the gage.

The following discharge measurement was made by C. C. Jacob in 

canal below gage:

November 10, 1910: l Width, 1 foot; area, 0.40 square foot; gage height, 3.50 feet; 

discharge, 0.35 second-foot.

SANTA CRUZ RIVER AND DITCHES AT TUCSON, ARIZ.

This station, which is located at Congress Street Bridge, Tucson, 

Ariz., was established October 15, 1905. The gage-height records 

were discontinued November 12, 1907, but discharge measurements 

have been made since then by the students of the University of 

Arizona under the direction of Mr. G. E. P. Smith, by whom the station is now maintained.

The Manning and Farmers ditches divert practically the entire 

flow during the low period of Santa Cruz River. These ditches are 

taken out just above the gaging station, and their flow is determined 

by current-meter or weir measurements, supplemented by daily 

records, kept by the ditch managers, of the amount of water contained in each. On April 16 and 17, 1908, a permanent Cippoletti 

weir was established on the Manning-ditch 3 miles below the head 

gate. This water is used to irrigate lands on the north and south 

sides of Santa Cruz River in and about Tucson.

Conditions of flow are changeable.

i All water diverted from river into canal by earth levee at gage.

SALT RIVER BASIN. 

SALT RIVER AT ROOSEVELT AND SALT AND VERDE RIVERS AT McDOWELL, ARIZ.

Salt River, though considered a tributary of the Gila, is larger both 

in catchment area and in volume of water carried. It receives the 

drainage from central Arizona, its principal tributary, the Verde, 

flowing in a general southeasterly direction from the mountains and 

tablelands south of Colorado River. The Verde Valley is in Yavapai 

County, Ariz., on the headwaters of the stream, and extends from a 

canyon above Camp Verde to a point about 10 miles below the fort. 

About a mile below the junction of the Verde and 30 miles above 

Phoenix, the Salt enters the plains of the Gila Valley.

The Salt River project of the United States Reclamation Service 

provides for the storage of water in a reservoir controlled by the 

Roosevelt dam, on Salt River at Roosevelt, Ariz., about 78 miles 

northeast of Phoenix. The diversion of water from Salt River by the 

Granite Reef dam, about 4 miles below the mouth of Verde River, 

into the old Arizona canal on the north side of the river and into the 

South canal on the south side of the river; the enlargement of the
COLORADO EIVEE BASIN. 215

Arizona canal; and the consolidation of the canal systems in the Salt 

River valley in the vicinity of Phoenix and Mesa into two systems 

receiving water from the Arizona and South canals. A power plant 

at the storage dam generates power from stored water in the reservoir and from water delivered from a power canal heading at a diversion dam in Salt River about 19 miles above the storage dam. Other 

power plants will be established on Salt River below Roosevelt and at 

drops in canals. A part of the power developed will be used for 

pumping water for extending the irrigated area and a part will be sold 

for industrial purposes.

The power-canal diversion dam, the power canal, the power plant, 

the Roosevelt dam, and the Granite Reef dam are completed; the 

improvements of the Arizona canal system and the wells for underground pumping are still under construction.1

Until the Roosevelt dam was completed (March, 1910) gaging 

stations were maintained at two points in Salt River basin by the 

United States Reclamation Service, as follows:

A station on Salt River at McDowell, Ariz., which is located onethird mile above the junction of Salt and Verde rivers, 30 miles northeast of Phoenix, 15 miles northeast of Mesa, and If miles above the 

Arizona canal diversion dam, was established April 30, 1897.

A station on Verde River at McDowell, 2 $ miles above the Arizona 

canal diversion dam and three-fourths of a mile above the mouth of 

the river, was established April 20, 1897.

The estimates of monthly discharge for 1910 have been computed from the reservoir records, based on amounts stored and 

amount drawn for this period. These estimates have been furnished 

by the United States Reclamation Service.

AGUA FRIA RIVER BASIN. 

AGFA FRIA RIVER NEAR GLENDALE, ARIZ.

Agua Fria River rises in the Prescott National Forest, Ariz., south 

of the Black Hills, and flows southward to its junction with the Gila, 

a short distance below the mouth of Salt River. New River, its 

principal trib.utary, enters about 11 miles above its mouth. During 

the greater part of the year New River is a dry wash. From the 

mountains the Agua Fria flows southward as a clear mountain torrent, 

but as it enters the plains of the Gila its waters sink into the broad 

sandy channel. In flood times great volumes of muddy waters pour 

through the usually dry channel into the Gila.

The gaging station, which is located at the old diversion dam of 

the Beardsley irrigation project at Camp Dyer, in sec. 28, T. 6 N., 

R. 1 E., Gila and Salt River base and meridian, 22 miles northwest of 

Glendale, was established November 10, 1910. The records derived 

from the observations at this point will show the amount of water 

available for storage at the proposed reservoir, a short distance above 

Camp Dyer.

Castle Creek enters about 4 miles above the station.

The diversion dam failed during the flood of 1895 when a portion 

of the masonry at each end was washed out.

At low and medium stages the stream flows through the larger 

opening, which is near the right bank. The gage for each channel is 

painted on the upstream face of the dam at the right of the opening.

At low water the channel changes slightly on account of the shifting 

sand in the bed of the stream. At high stages the dam acts as a 

permanent control.

At low and medium stages discharge measurements are made by 

wading near the dam. No equipment has yet been installed for 

making measurements at high water.

HASSAYAMPA RIVER BASIN. 

HASSAYAMPA RIVER NEAR WICKENBERG, ARIZ.

Hassayampa River rises south of the Sierra Prieta in the Prescott 

National Forest, and flows southward to its junction with the Gila 

about 25 miles below the mouth of the Agua Fria.

The mean annual precipitation at the headwaters of Hassayampa 

and Agua Fria rivers is about 18 inches; at the junction of these 

rivers with the Gila it is about 6 inches. The high slopes of the basin 

usually support a small amount of pine, fir, juniper, and oak having 

some commercial value. On the lower foothills there is a scattered 

growth of cacti, chaparral, and palo verde. Like the Agua Fria the 

Hassayampa is subject to violent freshets, whose waters reach the 

Gila only at times of flood; at other times the stream sinks into the 

sands.

The gaging station, which is located half a mile below Brill station 

on the Atchison, Topeka & Santa Fe Railway, about 4 miles below 

Wickenberg, in sec. 20, T. 7 N., R. 4 W., Gila and Salt River base 

and meridian, was established November 23, 1910.

A small ditch diverts water for irrigation at Wickenberg. No 

important tributaries enter below the station, which is about 45 

miles above the mouth of the river.

A vertical staff gage is bolted to the bedrock on the west bank of 

the stream about half a mile below the Brill ranch house.

The channel is straight for some distance above and below the 

station. The banks are low, and at high stages the river spreads to 

the base of the foothills. The bed of the stream is composed of 

sand and gravel and is very unstable. The location of the low-water 

channel changes with each flood.

Discharge measurements are made by wading near the gage..
