SURFACE WATER SUPPLY OF COLORADO RIYER BASIN,

1912.

By ROBERT FOLLANSBEE, E. A. PORTER, and H, D. PADGETT.

AUTHORIZATION AND SCOPE OF WORK.

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

measurements of flow made on streams in the United States during 

the calendar year 1912.

The data presented in these reports were collected by the United 

States Geological Survey under authority implied in the organic law 

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

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

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

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

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

1895, successive sundry civil bills passed by Congress have carried the 

following item and appropriations:

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

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

Annual appropriations for the fiscal year ending June 30 

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

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

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

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

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

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

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

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

In the execution of the work many private and State organizations 

have cooperated, either by furnishing data or by assisting financially 

in collecting the data. Acknowledgments for cooperation of the first 

kind are made in connection with the description of each station 

affected and of the second kind on page 16.

8 SUEFACE WATER SUPPLY, 1912, PAET IX.

Measurements of stream flow have been made at about 2,000 points 

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

Peninsula and the Yukon-Tanana region, Alaska, and hi the Hawaiian 

Islands. During 1912 gaging stations were maintained by the Survey 

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

discharge measurements were made at other points. In connection 

with this work data were also collected in regard to precipitation, 

evaporation, storage reservoirs, river profiles, and water power in 

many sections of the country and will be made available in the regular 

water-supply papers from time to time.

PUBLICATIONS.

A report for each calendar year has been prepared embodying the 

stream-flow data collected during that year. An index to the reports 

containing stream-flow measurements prior to 1904 has been published 

as Water-Supply Paper 119. Circulars are also available giving complete lists of the gaging stations maintained by the Survey to date, 

and a list of the reports relating to the water supply of the country.

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

discharge in annual reports; since 1902 both classes of data have been 

published in water-supply papers, and they are now being published 

hi 12 parts, as shown in the following table:

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

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

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

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

of the report.

DEFINITION OP TERMS.

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

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

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

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

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

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

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

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

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

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

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

the factors given in the following table of equivalents.
12 SURFACE WATER SUPPLY, 1912, PART IX.

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

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

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

regards time and area.

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

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

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

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

depth in inches.

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

commonly used in connection with storage for irrigation work.

CONVENIENT EQUIVALENTS.

computations:

EXPLANATION OF DATA.

For each regular current-meter gaging station the following data 

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

table of daily gage 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
14 SURFACE WATEE SUPPLY, 1912, PART IX.

channels, and backwater; also information regarding diversions 

which decrease the total flow at the measuring section. Statement® 

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

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, usually in the morning and in the evening. The gage height 

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

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

of ice in the streams or by backwater from obstructions are published 

as recorded, with suitable footnotes. The rating table is not applicable for such periods unless the proper corrections to the gage 

heights are known and applied. Attention is called to the fact that 

the zero of the gage is placed at an arbitrary datum and has no relation to zero flow or the bottom of the river. In general the zero is 

located somewhat below the lowest known flow, so that negative readings shall not occur.

The discharge measurements and gage heights are the base data 

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

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

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

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

ordinates and discharge in second-feet as abscissas.

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

corresponding to the observed gage heights as determined from the 

rating tables.

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

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

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

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

water surface was at crest height, and the corresponding discharge 

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

flow for the day when the mean gage height was lowest. The column headed "Mean" is the average flow in cubic feet for each second 

during the month. On this the computations for the remaining 

columns, which are defined on page 12, are based.

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

description of station, have been collected by the methods commonly 

used at current-meter gaging stations and described in standard textbooks.

meter 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.

In order to give engineers and others information regarding the 

probable accuracy of the computed results, footnotes are added to the 

daily discharge tables, stating the probable accuracy of the rating 

tables used, and an accuracy column is inserted in the monthly discharge table. For the rating tables "well defined" indicates, in general, that the rating is probably accurate within 5 per cent; "fairly 

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

are based on the plotting of the individual measurements with reference to the mean rating curve.

The accuracy column in the monthly discharge table does not 

apply to the maximum or minimum nor to any individual day, but to 

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

probable reliability of the observer, and knowledge of local conditions. 

In this column, A indicates that the mean monthly flow is probably 

accurate within 5 per cent; B, within 10 per cent; C, within 15 per cent; 

D, within 25 per cent. Special conditions are covered by footnotes.

Even though the monthly means for any station may represent 

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

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

omitting estimates of water diverted for irrigation or other use, and 

they should, therefore, be considered as only approximate, particularly for periods of irrigation or of low water. For these errors it is 

as a rule not feasible to make adequate correction.

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

afford any engineer the means of examining an|d adjusting to his own 

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

station and should not be used for other than preliminary estimates. 

The determinations of daily discharge allow more detailed studies of 

the variation in flow by which the period of deficiency may be determined
16 SURFACE WATER SUPPLY, 1912, PART IX.

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

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

 and published, and the engineer who makes use of the figures presented in these papers should verify all ratings and make such adjustments for earlier years as may seem necessary.

COOPERATION AND ASSISTANCE.

Work in New Mexico, in Utah, and in Arizona was carried on tinder 

cooperative agreement between the United States Geological Survey 

and the States.

In New Mexico, as a result of cooperation with Mr. James A. 

French, State engineer, a suboffice was opened at Santa Fe, and work 

actively resumed* The greater part of the field expense was paid by 

the State.

Special acknowledgments are also due to Mr. Caleb Tanner, State 

engineer of Utah.

In 1912 the State of Arizona passed an act providing that "The 

director of the Arizona Agricultural Experiment Station is hereby 

authorized and directed to formulate and enter into such agreements 

with the Director of the United States Geological Survey * * * 

as shall insure economy of expenditure and promptness of publication, and secure avoidance of duplication of work and other embarrassments incident to the operation of State and Federal agencies in 

the same field." On August 1, 1912, a joint cooperative agreement 

was signed by the Director of the United States Geological Survey 

and R. H. Forbes, director of the Arizona Agricultural Experiment 

Station. All work is carried on under the direct supervision of the 

United States Geological Survey, subject to the approval of the 

director of the Arizona Agricultural Experiment Station.

DIVISION OF WORK.

The field data in the Grand River drainage basin were collected 

under the direction of Robert Follansbee, district engineer, by H. B. 

Waha, J. L. Mathias, Raymond Richards, and R. H. Fletcher.

The work in New Mexico was under the general supervision of 

Robert Follansbee. Beginning with August, the work was in the 

direct charge of G. A. Gray, assistant engineer, who was assisted 

by F. O'Brien, J. E. Powers, C. J. Emerson, and E. L. Redding.

Field data in the Colorado drainage basin in Utah were collected 

under direction of E. C. La Rue, and E. A. Porter, district engineers, 

by J. C. Dort, G. H. Russell and Leonard Tanner.

Field data in Colorado drainage basin in Arizona were collected under 

the direction of H. D. McGlashan, by C. C. Jacobs and W. Richins.

NEW FORK RIVER BASIN. 

PINE CREEK NEAR PINED ALE, WYO.

Location. At an old Indian ford in sec. 22, T. 34 N., R. 109 W., one-third mile below 

the outlet of Fremont Lake and 4J miles north of Pinedale post office.

Records available.--July 22,1910, to June 30,1912. From April 2,1905, to October 

31, 1906, a station described under the same name was maintained half a mile 

below the present station. The records at the two points are not comparable, as 

two ditches divert the water between the two.

Drainage area. 130 square miles.

Gage. Chain gage; datum was raised 0.63 foot September 20, 1910; all readings 

have been referred to the present datum.

Channel. Apparently permanent.

Discharge measurements. Made from car and cable during high water and by 

wading during ordinary stages.

Storage. The natural storage afforded by Fremont Lake and various other small 

lakes on its headwaters gives Pine Creek a fairly uniform flow.

Winter flow. Ice causes backwater at the station during the winter months and the 

records are discontinued.

Diversions. Prior to July 1, 1912, there were adjudicated diversions of 77 secondfeet from Pine Creek. One ditch takes water above the station.

Accuracy. No measurements were made during 1912, but previous measurements 

indicate permanency of channel and therefore the 1911 rating curve has been 

used. Estimates believed reliable.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

Cooperation. Station maintained in cooperation with Eden Irrigation & Land Co.

Daily gage height, in feet, and discharge, in second-feet, of Little Sandy Creek near

Eden, Wyo., for 1912.

2£ miles above the point at which Dry Fork enters the creek.
ASH LEY CREEK BASIN. 57

Records available. October 8, 1911, to December 31, 1912. Records are also 

available for a point below the mouth of Dry Fork from March 18,1900, to December 31, 1904.

Drainage area. 107 square miles.

Gage. Vertical staff on right bank.

Channel. Shifts during high water.

Discharge measurements. Made by wading.

Winter flow. Very little ice forms at this station.

Diversions. Above all diversions.

Artificial regulation. Operation of power plant probably has no effect on flow at 

station.

Accuracy. Poor, owing to infrequent gage readings and lack of discharge measurements.

Cooperation. Maintained in cooperation with the United States Forest Service.

The following discharge measurement was made by J. C. Dort: September 6: 

Gage height, 1.81; discharge, 62.7 second-feet.

Daily gage height, in feet, of Ashley Creek near Vernal, Utah, for 1912.

LAKE FORK NEAR MYTON, UTAH.

Location. In sec. 21, T. 3 S., B. 2 W. f TJinta special base and meridian, 3 milesabove 

Myton, Utah, about one-half mile above the junction of Lake Fork and Duchesne 

Biver, and about 100 yards below a county highway bridge.
DUCHESNE EIVEE BASIN. 61

Records available. July 3, 1900, to December 31, 1903; June, 1907, to November

30, 1910; July 26, 1911, to December 31, 1912. 

Drainage area. Not known. 

Gage. Chain gage. Several different gages and data have been used during the life

of the station. Inclined staff at same datum as chain gage used after September

8, 1912.

Channel. Fairly permanent.

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

Winter flow. Ice affects the relation of gage height to discharge for practically the

entire winter period. 

Diversions. Several canals of the United States Indian Service and also some

privately owned canals take water from this stream above the station for

irrigation. 

Accuracy. Excellent.

PRICE RITER NEAR HELPER, UTAH.

Location. In sec 25 or 36, T. 13 S., R. 9 E., Salt Lake base and meridian, at settlement known locally as Spring Glenn, 2J miles south of Helper, Utah; about 2 

miles above the diversion dam of the Price River Irrigation Co., and 300 feet west 

of the main line of the Denver & Rio Grande Railroad, 4 miles below mouth of 

White Creek.

Records available. February 21, 1904, to December 31, 1912.

Drainage area. 530 square miles.

Gage. Vertical staff on left bank.
PRICE BIVER BASIN. 69

Channel. Shifting during sudden floods.

Discharge measurements. Made from cable and car.

Winter flow. Relation of gage height to discharge is affected by ice during the 

winter.

Diversions. Records indicate the amount of water available for the Price River 

Irrigatipn Co. and for the canals for the town of Price, which divert a few miles 

below the station. No important diversions above the station.

Regulation. The Price River Irrigation Co. haa a reservoir with a capacity of about 

24,000 acre-feet (ultimately to be increased to 30,000 acre-feet) on Gooseberry 

Fork of Price River about 40 miles above the station. Stored water is turned out 

of this reservoir during the irrigation season and passes the gaging station on its 

way to the canal below.

Accuracy. Good.

NOTE. Dafly discharge determined as follows: Feb. 1 to 10, estimated because of ice; Mar. 13 to May 31. 

from a well-defined rating curve; June 1 to Oct. 27, from a fairly well-defined curve; Oct. 28 to 31, by indirect 

method for shifting channels; Nov. 1 to Dec. 19, from a fairly well-defined curve; Dec. 20 to 31. estimated 

because of ice. Discharge for periods, August to November, when gage was covered with silt, based on 

observer's notes regarding depth of water in river and comparison with records on the streams in Castle 

Valley, which unite to form tne San Rafael. Mean discharge January to March estimated.

PERRON CREEK NEAR CASTLEDALE, UTAH.

Location. About 8 miles below the town of Ferron, Utah, at a point known locally 

as Paradise, in sec, 35, T. 19 S., R. 8 E., Salt Lake base and meridian; 2 miles 

below the point of diversion of the Paradise canal.

Records available. June 12, 1911, to December 31, 1912.
SAN RAFAEL BIVEE BASIN. 77

Drainage area. Not measured.

Gage. Inclined staff on left bank.

Channel. Shifting during flood periods.

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

Winter flow. Ice affects the relation of gage height to discharge during the winter 

months.

Diversions. Below all diversions except the Fred Anderson ditch.

Artificial regulation. Flow is affected at times as the result of manipulating the 

head gates of the various canals above the station.

Accuracy. Fair only, owing to shifting character of stream bed and diurnal fluctuations at certain seasons of the year.

Location. At Cunha ranch, about 7 miles northwest of Huntington, Utah, in sec. 6,

T. 17 S., R. 8 E., Salt Lake base and meridian. 

Records available. May 3, 1909, to December 31, 1912. 

Drainage area. 158 square miles.
SAN EAFAEL KIVER BASIN. 79

Gage. Vertical staff in two sections, and sloping gage, both at same datum, used 

during 1912.

Channel. Shifting at extreme high stages.

Discharge measurements. Made by wading at low stages and from a cable and 

car at high stages.

Floods. Extremely high floods occasionally occur at this station in July and August.

Winter flow. The stream is frozen entirely over during the greater part of the winter. 

Estimates of winter flow are approximate.

Diversions. Above all diversions (except Cunha's ditch) and below all main tributaries except Fish Creek. Several small ditches divert from tributaries above 

the station.

Artificial regulation. A small storage reservoir on Huntington Creek above the 

station controls the distribution of the flow to a slight extent.

Accuracy. Fair except for high stages.

for several miles above the station. 

Records available. July 29, 1904, to September 30, 1909; September 20, 1910, to

November 30,1912.
GRAND EIVEE BASIN. 83

Drainage area. 107 square miles (measured from Forest atlas).

Gage. Vertical staff.

Channel. Practically permanent.

Discharge measurements. Made from highway bridge at the gage.

Winter flow. Ice forms along the edges, but springs keep the river open.

Diversions and storage. There are court decrees for diversions of 716 second-feet 

from the headwaters above the station. Of this amount 525 second-feet are for 

diversion across the divide into the headwaters of the Cache la Poudre. There 

is also a reservoir decree for 19,000 acre-feet from the flood water.

Accuracy. The meager gage heights for the greater part of the year make the estimates of discharge only fair or, possibly, good.

Cooperation. During 1912 the station was maintained in cooperation with the 

United States Forest Service.

GRAND RIVER AT SULPHUR SPRINGS, COLO.

Location. At the bridge connecting the Denver, Northwestern & Pacific Railway 

station with the town of Sulphur Springs, in sec. 2, T. 1 N., R. 78 W. Nearest 

tributary, Beaver Creek, enters the river 2 miles below the station.

Records available. July 22, 1904, to September 30, 1909, a station was maintained 

at this point by the United States Geological Survey; September 23, 1910, to 

November 30, 1912.
GRAND EIVER BASIN. 85

Drainage area. 946 square miles (measured from Hayden's atlas).

Gage. Chain gage; datum the same as that of the gage used originally.

Channel. Somewhat shifting.

Discharge measurements. Made from bridge during high and ordinary stages 

and by wading during low water.

Winter flow. The river is frozen over during the winter months and discharge 

measurements are made to determine the winter flow.

Diversions. Between this station and that near Granby there are court decrees for 

diversions of 100 second-feet from Grand River and 662 second-feet from intervening tributaries. There is also a reservoir decree for 31,300 acre-feet from the 

flood waters of Grand River.

Accuracy. Owing to the shifting of the channel, the estimates of discharge can not 

be considered better than fair or possibly good. Estimates have been made only 

for days on which the gage was read.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

GRAND RIVER NEAR KREMMLING, COLO.

Location. At the entrance to Gore Canyon, 3 miles southwest of Kremmling, in 

sec. 23, T. 1 N., R. 81 W. Nearest tributary, Blue River, enters a mile below 

Kremmling.

Records available. July 24, 1904, to November 30,1912.

Drainage area. 2,380 square miles.

Gage. Automatic recording gage, except during the winter months when a staff 

gage is read.

Channel. Somewhat shifting; the bed scours at high stages and silts during low.

Winter flow. Although the river is frozen entirely across at the station, there is 

little, if any, backwater, as shown by discharge measurements made during the 

winter. Rapids below the station remain open and thus prevent backwater except 

for short periods when ice jams on the rapids.

Kremmling reservoir site. The station is located at the site of the proposed 

Kremmling reservoir of the United States Reclamation Service. With a 200-foot 

dam at the mouth of Gore Canyon the capacity of the reservoir would be 2,200,000 

acre-feet.

Diversions. Between this station and that at Sulphur Springs there are court decrees 

for diversions of 34 second-feet from Grand River and 2,315 second-feet from 

intervening tributaries exclusive of diversions for placer mining in the Blue River 

drainage.
GBANB RIVER BASIN. 87

Accuracy. Although the channel is somewhat shifting, sufficient discharge measurements have been made to form a basis for fairly reliable estimates of flow.

Cooperation. During 1912 the station was maintained by State engineer, who 

furnished records complete for publication.

a Estimated. 

GRAND RIVER AT GLENWOOD SPRINGS, COLO.

Location. At Glen wood Springs, at the point where the discharge from the hot 

springs enters the river. No Name Creek enters Grand River about 2 miles above 

the station and Roaring Fork enters one-half mile below.

Records available. May 12, 1899, to December 31, 1912.

Drainage area. 4,520 square miles (measured from Nell's map of Colorado).
GRAND EIVEB BASIN. 89

Gage. Chain gage originally installed at the railroad bridge just above the Roaring 

Fork, but in 1900 a staff gage was installed at the present location. Since 1902 a 

number of automatic gages referred to the staff gage datum have been used, the 

present one being a Friez gage.

Channel. Slightly shifting.

Discharge measurements. Made from a car and cable stretched beneath the State 

Street Bridge, which crosses the river one-third mile below the gage.

Winter flow. Ice never forms at the station, as the hot water from the springs keeps 

the water above the freezing point.

Artificial control. The Shoshone power plant of the Central Colorado Power Co., 

6 miles above Glenwood Springs, has sufficient pondage to withhold the flow of 

the river for a portion of the day during low-water periods.

Diversions. Between this station and the one near Kremmling there are court 

decrees for a diversion of 13 second-feet from Grand River and 1,508 second-feet 

from the intervening tributaries.

Accuracy. Conditions are favorable for accurate results and the estimates are considered reliable.

Cooperation. Station maintained in cooperation with the United States Forest 

Service and Central Colorado Power Co.

GRAND RIVER NEAR PALISADES, COLO.

Location. At the State bridge 2 miles above Palisades, about sec. 3, T. 11 S., R. 98 

W. Nearest important tributary, Plateau Creek, enters about 6 miles above the 

station.

Records available. April 9, 1902, to December 5, 1912.

Drainage area. 8,550 square miles.

Gage. Chain gage; location and datum unchanged.

Channel. Practically permanent.
GRAND BIVER BASIN.

Discharge measurements. Made from bridge to which the gage is attached. 

Prior to 1906 measurements were made from the suspension bridge at Palisades, 

where conditions were less favorable for accurate determination of discharge.

Winter flow. The river usually freezes over a portion of the year, but except for 

slush and ice and an occasional thin ice cover the effect on the gage heights is 

slight.

Diversions. There are court decrees for diversions of 420 second-feet from Grand 

River and 2,500 second-feet from intervening tributaries between Palisades and 

the Glenwood Springs station. The proposed high line canal of the United States 

Reclamation Service will divert 700 second-feet 7 miles above the Palisades 

station. Below the station the Grand Valley Irrigation Co. has a diversion of 

400 second-feet.

Accuracy. Conditions are favorable for accurate results, and the estimates should 

be reliable.

Cooperation. Field data furnished by the United States Reclamation Service.

GRAND RIVER NEAR FRUITA, COLO.

Location. At highway bridge 1J miles south of Fruita, in sec. 20, T. 1 N., R. 2 W., 

TJte principal meridian. Nearest important tributary, Little Salt Wash, enters 

a mile below the station; Gunnison River enters at Grand Junction, about 12 

miles above.

Records available. Flood records during 1908,1909, and 1910; May 4,1911 (station 

established), to December 5, 1912.

Drainage area. 16,800 square miles (Hayden's Atlas).

Gage. Chain gage; datum was raised 0.05 foot May 3,1911.

Channel. Practically permanent.
GRAND RIVER BASIN. 93

Discharge measurements. Made from the highway bridge.

Winter flow. The river is frozen over during a portion of the year and readings

are taken to water surface through a hole in the ice. 

Diversions. Between the Palisades station and Fruita nearly 500 second-feet are

diverted during the irrigation season. 

Maximum stage. Since the establishment of the station the maximum stage has

been 15.0 feet, which occurred June 9,1909. The highest stage known was about

18.5 feet on July 4, 1884. 

Accuracy. Owing to insufficient high-water measurements, estimates of discharge

have not yet been made. The base data are considered reliable. 

Cooperation. The gage heights are furnished through the courtesy of the United

GRAND LAKE OUTLET AT GRAND LAKE, COLO.

Location. At the footbridge at the outlet of Grand Lake, in sec. 6, T. 3 N., R. 75 W.,

half a mile south, of Grand Lake post office. No tributary between Grand Lake

and the North Fork of Grand River. 

Records available. July 3, 1904, to September 30, 1909; September 20, 1910, to

November 30, 1912.

Drainage area. 62 square miles (measured from Hayden's atlas). 

Gage. Vertical staff; location and datum unchanged. Being so close to the outlet,

the gage heights represent the level of the water surface in Grand Lake. 

Channel. Somewhat rough but permanent.

Discharge measurements. Made by wading at various points below the gage. 

Winter flow. 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 coining out of

Grand Lake. 

Diversions. No water is diverted below the station on the North Inlet. There are

court decrees for diversion above that point. 

Artificial control. As the area of Grand Lake is only 700 acres, or a little more than

1 square mile, its effect as a natural reservoir on the run-off is not great. 

Accuracy. Owing to the scarcity of gage heights the records at this station can not

be considered better than fair or possibly good. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

FEASEB BIVEB NEAR ARROW, COLO.

Location. One-fourth mile from Idlewild ranger station, in the Arapahoe National 

Forest, in sec. 3, T. 2 S., R. 75 W., sixth principal meridian, 2 miles from Arrow.

Records available. September 23, 1910, to November 27, 1912.

Gage. Vertical staff whose location and datum have remained unchanged.

Channel. Shifting after high water.

Discharge measurements. Made from log bridge to which the gage is attached.

Winter flow. The control remains open during the greater part of the winter and 

there is little if any backwater at the gage except for short periods.

Diversions. There is a court decree for the diversion of 53 second-feet across the 

divide from the headwaters above the station. There are court decrees for diversions of 72 second-feet from Fraser River below.

Accuracy. Owing to the high altitude of the drainage basin it is probable that at 

certain seasons there are diurnal fluctuations caused by the alternate melting and 

freezing. Therefore the mean daily gage height as determined by one or two 

readings may be considerably in error, and the estimates of discharge can not 

be considered better than fair.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

NOTE. Daily discharge computed from two fairly well defined rating curves as follows: Jan. 1 to June 5 

the curve for 1911 was applicable; from July 2 to Nov. 21 a curve was used which was based on one measurement in 1912 and one in 1913. Discharge interpolated for days for which gage heights are missing in July 

and October. Gage observations infrequent during January, June, and November, and estimates of daily 

discharge are published only for days of such observations. Interpolated values for days for which gage 

heights are missing during this period were used in estimating monthly discharge.

WILLIAMS FORK NEAR SCHOLL, COLO.

Location. About 5 miles southeast of Scholl, Colo., in sec. 3, T. 2 S., R. 78 W., at 

the Horseshoe ranger station in the Arapahoe National Forest. Nearest important 

tributary, the South Fork, enters from the east 1 mile below the station.

Becords available. September 22, 1910, to June 30, 1912.

Drainage area. 141 square miles (measured from Forest Atlas).

Gage. Vertical staff.

Channel. Data too meager to determine.

Discharge measurements. Made by wading a short distance below the gage.

Winter flow. Ice causes some backwater during the winter months.

Diversions. There are court decrees for the diversion of 858 second-feet from Williams Fork above the station. Of this amount 700 second-feet are to be diverted 

to the eastern slope. This latter diversion has not yet been made.

Accuracy. As the station has not been completely rated no estimates of discharge 

are available.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

WILLIAMS FORK NEAR SULPHUR SPRINGS, COLO.

Location. On highway bridge at Field's ranch, 4 miles above the mouth of the 

river, about sec. 36, T. 1 N., R. 79 W. Nearest tributary is a email stream that 

enters from the west 2 miles below the station.

Becords available. July 25, 1904, to December 7, 1912.

Drainage area. 185 square miles (measured from Forest Atlas).

Gage. Vertical staff; location and datum unchanged.

Channel. Practically permanent.

Discharge measurements. Made from bridge to which the gage is attached.

Winter flow. The main channel is kept open by springs, but ice forms along the 

edges and slush ice frequently forms. The morning readings are usually affected 

by backwater from ice, but the afternoon readings are practically unaffected. 

The winter gage heights during 1912 were taken in the afternoon.

Diversions. There are court decrees for the diversion of 502 second-feet from Williams Fork between the station near Scholl and Sulphur Springs. There are also 

two storage decrees for 80,700 and 1420 acre-feet, respectively, from Williams 

Fork.

Accuracy. Conditions are favorable for accurate results and the estimates should be 

reliable.

Cooperation. Since 1911 this station has been maintained in cooperation with the 

State engineer.

BLUE RIVER AT DILLON, COLO.

Location. At the cemetery bridge on the outskirts of Dillon, in sec. 18, T. 5 S., 

R. 77 W., on the edge of the Leadville National Forest, a short distance above the 

mouth of Snake River. Tenmile Creek also enters below the station.

Records available. October 15, 1910, to December 31, 1912.

Drainage area. 110 square miles (measured from Forest Atlas).

Gage. Vertical staff; location and datum unchanged.

Channel. Practically permanent.

Discharge measurements. Made by wading near by.

Winter flow. Ice causes backwater during the winter and discharge measurements 

are made to determine the flow.

Diversions. There are court decrees for diversions of 2.3 second-feet from Blue 

River above the station and 68 second-feet below. There is an unadjudicated 

diversion from the headwaters of the Blue across Boreas Pass to Tarryall Creek. 

There are also decrees for diversions of 5 second-feet from tributaries entering 

above. In addition, there are decrees for placer mining, where practically all of 

the water used is returned to the river.
GRAND EIVEB BASIN. 103

Accuracy. Owing to the high altitude of this Btation alternate melting and freezing 

is likely to cause considerable diurnal fluctuations at certain seasons of the year, 

and the mean daily gage height based on one gage reading may be considerably 

in error. For this reason it is probable that the estimates can not be considered 

better than fair for certain months.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

TENMELE CREEK AT DILLON, COLO.

Location. At the highway bridge in Dillon, Colo., in sec. 18, T. 5 S., E. 77 W., 300 

yards above the mouth of the creek. Nearest tributary, Canon Creek, enters 

from the west about 4 miles above the station.

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

Drainage area. 113 square miles (measured from Forest Atlas).

Gage. Vertical staff; location and datum unchanged.

Channel. Practically permanent.

Discharge measurements. Made by wading near the bridge.
GRAND BIVER BASIN. 105

Winter flow Ice causes backwater during the winter months, and discharge measurements are made to determine the flow during that period.

Diversions. There are court decrees for diversions of 3.7 second-feet from Tenmile 

Creek above the station and 14.5 second-feet from tributaries entering above.

Accuracy. Owing to the high altitude of this station alternate melting and freezing 

are likely to cause considerable diurnal fluctuations at certain seasons of the year, 

and the mean daily gage height based on one gage reading may be considerably 

in error. For this reason it is probable that the estimates can not be considered 

better than fair for certain months.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

SNAKE RIVER AT DILLON, COLO.

Location. At a highway bridge 200 yards above the mouth of the river in sec. 18, 

T. 5 S., R. 77 W. Nearest tributary is a small stream that enters from the north 

1 mile above the station.

Records available. October 15, 1910, to November 25, 1912.

Drainage area. 92 square miles (measured from Forest Atlas).

Gage. Vertical staff; location and datum unchanged.

Channel. Practically permanent.

Discharge measurements. Made by wading above the bridge.
GBAND BIVEE BASIN. 107

Winter flow. Ice gorging causes backwater of varying amount. During 1912 the

control remained open most of the winter. 

Diversions. There are court decrees for diversions of 4.5 second-feet from Snake

River above the station and 11 second-feet from tributaries entering above. 

Accuracy. Owing to the high altitude of this station, alternate melting and freezing

are likely to cause considerable diurnal fluctuations at certain seasons of the year,

and the mean daily gage height based on one gage reading may be considerably

in error. For this reason it is probable that the estimates can not be considered

better than fair. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

EAGLE RIVER AT RED CLIFF, COLO.

Location. In sec. 30, T. 6 S., R. 80 W., in the town of Red Cliff, in the Holy Cross 

National Forest, 100 yards above mouth of Turkey Creek, and 1 mile above the 

mouth of Homestake Creek.

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

Drainage area. 74 square miles (measured from topographic sheet).

Gage. Chain gage; location and datum unchanged.

Channel. Shifting after high water.
GRAND RIVER BASIN. 109

Discharge measurements. Made from highway bridge at station during high 

water and by wading at ordinary stages.

Winter flow. Little if any ice forms at this station.

Diversions. There are court decrees for diversions of 22 second-feet from Eagle 

River and tributaries above the station; 18.5 second-feet of this amount for diversion to the Arkansas basin.

Accuracy. Owing to the high altitude of the drainage basin, alternate melting and 

freezing possibly cause diurnal fluctuations of stage at certain seasons; therefore, 

the mean daily stage as determined from two readings per day may be somewhat 

in error. For that reason the estimates can not be considered better than good.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

NOTE. Channel open during winter months. Increased stage Jan. 24, Feb. 15 and 16, was due to melting snow. The rise May 25 was caused by the opening of the gates of the Pando ice pond, located above 

the station, and the low stages, Sept. 28 to 30, were caused by the filling of the Pando ice pond. Rise of 

Nov. 17 due to slush ice.

EAGLE EIVEE AT EAGLE, COLO.

Location. At the highway bridge at Eagle, in Eagle County, Colo., three-fourths of

a mile above the mouth of Brush Creek. 

Records available. March 12, 1905, to February 10, 1907, at site a short distance

below the mouth of Brush Creek; January 17, 1911, to November 30, 1912, at

present site. 

Drainage area. 630 square miles (measured from Forest Atlas). Revised since

publication of 1911 report.
GRAND EIVEE BASIN. Ill

Gage. Vertical Btaff.

Channel. Practically permanent.

Discharge measurements. Made from highway bridge at ordinary and high stages

and by wading during low water. 

Winter flow. Ice causes backwater during the winter. Discharge measurements

are made to determine the winter flow. 

Diversions. Between Eagle and the station at Red Cliff there are court decrees for

diversions of 50 second-feet from Eagle River and for diversions of 286 second-feet

from intervening tributaries. Between Eagle and the mouth there are decrees

for 28 second-feet from Eagle River. 

Accuracy. Except for the meager gage heights, which make the estimates for the

later part of the year somewhat uncertain, the records are considered good. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

NOTE. Daily discharge computed from a fairly well-defined curve. Estimates of discharge Jan. 1 

to Mar. 15 based on one measurement in February and comparison with almost uniform flow at Red Cliff, 

where Eagle River remains open. Mean discharge Mar. 1 to 15, estimated, 90 second-feet, Nov. 23 to 30, 

180 second-feet. Discharge interpolated for days on which gage was not read. During August discharge 

is given only for days on which gage was read owing to scarcity of gage readings and to the variation of 

The mean monthly discharge for August has been estimated from these interpolated discharges.

HOMESTAKE CREEK AT RED CLIFF, COLO.

Location. In sec. 30, T. 6 S., R. 80 W., one-fourth mile above the mouth of the

creek and three-fourths of a mile from Red Cliff; below all tributaries. 

Records available. January 8, 1911, to November 12,1912. 

Drainage area. 64 square miles (measured from topographic sheet).
GEAND RIVER BASIN. 113

Gage. Vertical staff.

Channel. Apparently permanent.

Discharge measurements. Made by wading near by.

Winter flow. Ice causes backwater, and discharge measurements are made to 

determine the winter flow. 

Diversions. There are court decrees for diversions of 1.2 second-feet from Homestake

Creek. 

Accuracy. Owing to the high altitude of the drainage basin, alternate melting and

freezing may cause diurnal fluctuations in stage during certain seasons. Therefore

the mean daily gage height as determined from one reading may be considerably

in error. In view of the foregoing, and of. the many interpolated discharges, the

estimates can not be considered better than fair. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

GRAND EIVEB BASIN. 117

BRUSH CBEEK AT EAGLE, COLO.

Location. At railroad bridge in sec. 6, T. 5 S., R. 84 W., three-fourths of a mile west 

of Eagle and 300 yards above the mouth of the creek. Nearest tributary a small 

stream that enters from the south half a mile above the station.

Records available. January 18, 1911, to November 21,1912.

Drainage area. 146 square miles (measured from Forest Atlas).

Gage. Vertical staff.

Channel. Shifting.

Discharge measurements. Made from footbridge and by wading near by.

Winter flow. Ice causes backwater during the winter months. Measurements are 

made to determine the discharge.

Diversions. There are court decrees for diversions of 115 second-feet from Brush 

Creek and 27 second-feet from tributaries all above the station.

Accuracy. Owing to the meager gage heights during the summer months, estimates 

can be made only when gage heights are available; daily estimates for the remainder of the year are not considered better than fair.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

NOTE. Discharge determined as follows: Jan. 1 to May 31, from a fairly well defined curve; June 1 to 

30, by the indirect method of shifting channels. Discharge interpolated for days on which gage was not 

read and for days when gage heights are distorted by ice. Mean monthly discharge July to November 

estimated from daily discharge obtained by indirect method and from a curve based on 1 measurement 

made Sept. 24,1912. The interpolated values for this period, July to November, are not published, owing 

to infrequency of gage heights and measurements.

NO NAME CREEK NEAE GLENWOOD SPEINGS, COLO.

Location. In sec. 5, T. 5 S., R. 88 W., 4 miles from Glen wood Springs, and 1J miles 

above the mouth of the creek. Nearest tributary, a small stream that enters some 

distance below the station.

Records available. January 5, 1911, to October 26, 1912.
GRAND RIVER -BASIN. 119

Drainage area. Not measured.

Gage. Vertical staff.

Channel. Shifting.

Discharge measurements. Made by wading near by or from footbridge.

Winter flow. Gage heights at this station show slight effect of ice.

Diversions. No water is diverted above the station, but the records do not represent 

the natural run-off of the drainage basin, as about half the run-off of Grizzly Creek 

is diverted into No Name Creek above the station. A short distance below the 

station are the head works of the Glenwood Light & Water Co. canal, which has 

a decree for 12 second-feet.

Accuracy. Owing to the shifting channel and insufficient discharge measurements, 

no estimates of discharge have been made. The base data are considered reliable.

Cooperation. Station maintained in cooperation with the United States Forest 

Service and the Glenwood Light & Water Co.

GRAND EIVEE BASIN. 121

ROARING FORK AT ASPEN, COLO.

Location. In sec. 7, T. 10 S., R. 84 W., at Aspen, Colo., above Castle, Maroon, and

Hunter creeks.

Records available. January 1, 1911, to December 5, 1912. 

Drainage area. 109 square miles (measured on topographic sheet). 

Gage. Vertical staff.

Channel. Very rough and slightly shifting. 

Discharge measurements. Made by wading, except during high water, when

bridge is used. 

Winter flow. Ice causes backwater during the winter; discharge measurements are

made to determine the winter flow. 

Diversions. The Salvation ditch, which has a decree for 42 second-feet, diverts

water above the station usually from the middle of May to the middle of

September. 

Accuracy. Owing to the high altitude of the drainage basin, alternate melting and

freezing probably cause diurnal fluctuations in stage at certain season s. Therefore

the mean daily stage, as determined from one reading, may be somewhat in error.

For this reason the estimates can not be considered-better than fair. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

ROARING FORK AT GLENWOOD SPRINGS, COLO.

Location. On bridge 500 feet above the mouth of the river in Glen wood Springs.

Nearest important tributary enters about 3 miles above the station. 

Records available. April 6, 1906, to September 30, 1909; September 21, 1910, to

December 31, 1912.

Drainage area. 1,450 square miles (Nell's map of Colorado, 1903). 

G-age. Chain gage; location and datum unchanged.
GRAND RIVER BASIN. 123

Channel. Practically permanent, but rough. Extremely high water in Grand River 

may cause backwater at the gage. Measurements made at stages as high as 5.7 

feet on Roaring Fork and 9.2 feet on Grand River have shown no backwater effect.

Discharge measurements. Made from highway bridge.

Winter flow. Surface ice rarely forms entirely across the river, but slush and anchor 

ice frequently occur. Discharge measurements sometimes" show backwater from 

ice.

Diversions. There are court decrees for diversions of 196 second-feet from Roaring 

Fork above the station, and 795 second-feet from the various tributaries.

Accuracy. Conditions are favorable for accurate results; estimates should be reliable.

Cooperation. Since. 1910 the station has been maintained in cooperation with the 

United States Forest Service.

CASTLE CREEK NEAR ASPEN, COLO.

Location. In see. 35, T. 10 S., R. 85 W., in the Sopris National Forest, on the highway 

bridge 4 miles above Aspen. No tributary between the station and the mouth of 

the creek except small gulches that cany spring run-off. Nearest tributary above, 

Conundrum Creek, enters about 6 miles upstream.

Records available. February 16, 1911, to December 5, 1912.

Drainage area. 72 square miles (measured on topographic sheets).
GRAND RIVER BASIN. 127

Gage. Vertical staff. On February 29, 1912, the gage was moved to the opposite

side of the creek and to the lower side of the bridge. The datum was lowered

1.00 foot, but the difference in gage readings varies. All 1912 gage heights are

referred to the latter datum. 

Channel. Apparently permanent. 

Discharge measurements. Made from the bridge during high water and by wading

at ordinary stages. 

Winter flow. Ice causes some backwater at this station, and discharge measurements

are made to determine the flow. 

Diversions. No water is diverted above the station. The Roaring Fork Light &

Power Co. and the Newman mine divert water from Castle Creek below the

station. 

Accuracy. Owing to a lack of high-water measurements no estimates of discharge

have yet been made. The mean daily stage as determined from one reading may

be somewhat in error, as a result of the high altitude of the station, and, therefore,

the gage heights can not be considered better than fair. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

MAROON CREEK NEAR ASPEN, COLO.

Location.-T-In sec. 22, T. 10 S., R. 85 W., in the Sopris National Forest, just above

the headgate of the Roaring Fork Light & Power Co., 5 miles above Aspen, Colo.

Nearest tributary, Willow Creek, enters some distance below the station. 

Records available. January 1, 1911, to December 2,1912. 

Drainage area. 42 square miles (measured from topographic sheet). 

Gage. Vertical staff. 

Channel. Shifting. 

Discharge measurements. Made by wading, except during high water, when

they are made from a footbridge. 

Winter flow. Discharge measurements indicate that ice does not cause backwater

at this station. 

Diversions. There are one or two very small diversions for meadow irrigation above

the station; the Roaring Fork Light & Power Co. diverts water just below. 

Artificial control. Snowslides upstream sometimes choke the channel, holding the

water back temporarily. 

Accuracy. Owing to meager gage heights, diurnal fluctuation of stage, and shifting

channel estimates can only be considered fair. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

SNOW MASS CREEK AT SNOW MASS., COLO.

Location. On a private bridge at Stewart's ranch, in sec. 27, T. 8 S., H. 86 W., 

half a mile from Snow Mass, Colo. No tributaries between the station and the 

mouth of the creek.

Records available. February 21, 1911, to November 25, 1912.

Drainage area. 89 square miles (measured from topographic sheet and Forest 

Atlas).

35658° WSP 329 14 9
130 SURFACE WATEE SUPPLY, 1912, PART IX.

Gage.- -Vertical staff.

Channel. Practically permanent.

Discharge measurements. Made from the bridge during high water and by 

wading at other times.

Winter flow. Ice causes backwater during the winter months, and discharge measurements are made to determine the flow.

Diversions. There are court decrees for diversion of 29 second-feet from the main 

stream above the station and 7 second-feet below. There are also decrees for 

diversions of 73 second-feet from tributaries entering above.

Accuracy. Owing to the meager gage heights, estimates have been made only for 

the days when the gage was read, except during the last half of the year, when the 

flow was gradually decreasing. These estimates are considered fair.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

FRYING PAN CREEK AT NORRIE, COLO.

Location. At the highway bridge in Nome, in sec. 28, T. 8 S., R. 83 W., in the

Sopris National Forest, 1 mile above the entrance of the North Fork. 

Records available. February 18, 1911, to November 30, 1912. 

Drainage area. 112 square miles (measured from topographic sheet). 

Gage. Vertical staff.

Channel. Slightly shifting after high water. 

Discharge measurements. Made from the bridge. 

Winter flow. Ice probably causes backwater during the winter months. 

Diversions. No water is diverted from this creek either above or below the station.
132 SURFACE WATER SUPPLY, 1912, PART IX.

Accuracy. Owing to the high altitude of the drainage basin, alternate melting and 

freezing causes diurnal fluctuations of stage at certain season; therefore the mean 

daily stage as determined from one reading may be considerably in error and the 

estimates can not be considered better than fair or, possibly, good.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

NOTE. Daily discharge computed from two well-defined curves which merge at gage height 4.2 feet. 

The high water of May to July caused the change in the low-water part of curve. Mean discharge January 

to March estimated as 27 second-feet, from two discharge measurements and comparison with the constant 

flow at Thomasville, where stream remains open. Discharge interpolated for days for which gage heights 

are missing.

FRYING PAN CREEK AT THOMASVILLE, COLO.

Location. At a private bridge in sec. 12, T. 8 S., R. 84 W., in the Sopria National 

Foreat, three-fourths of a mile below Thomasville. Nearest tributary, Jakeman 

Creek, entera 100 yards above.

Records available. January 2, 1911, to November 30, 1912.
134 SUEFACE WATER SUPPLY, 1912, PAET IX.

Drainage area. 190 square miles (measured from Forest Atlas).

Gage. Vertical staff.

Channel. Practically permanent.

Discharge measurements. Made from bridge during high water and by wading 

at ordinary stages.

Winter flow. Ice causes backwater during the winter months and discharge measurements are made to determine the flow.

Diversions. As there are no court decrees for diversion of water above the station, it 

is probable that the records represent the natural run-off from the drainage basin.

Accuracy. Conditions favorable for fairly accurate determination of discharge; 

results should be reliable.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

NORTH FORK OF FRYING PAN CREEK NEAR NORRIE, COLO.

Location. On a highway bridge in sec. 21, T. 8 S., R. 83 W., in the Sopria National 

Foreat, about 1 mile from Norrie. No tributaries between the atation and the 

mouth of the creek.

Records available. February 18, 1911, to December 31, 1912.

Drainage area. 42 square miles (measured from topographic sheet).

Gage. Vertical staff.

Channel. Practically permanent.
136 SURFACE WATER SUPPLY, 1912, PART IX.

Discharge measurements. Made from the bridge during high water and by

wading at ordinary stages.

Winter flow. Ice causes little if any backwater during the winter months. 

Diversions. No water is diverted above the station, so the records represent the

natural run-off. 

Accuracy. Owing to the scattering gage heights and the probable error in mean

daily stage as determined from one reading, the estimates can not be considered

better than fair. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

miles above the entrance of East Elk Creek, a stream so small that it carries very

little water except possibly during the spring. 

Records available. January 19, 1911, to December 31, 1912. 

Drainage area. 122 square miles, including the area drained by West Elk Creek

(measured from Forest Atlas). 

Gage. Vertical staff. The gage was originally placed 300 yards farther downstream,

but was moved to its present position September 23, 1911; relation between the

datums of the two gages not determined. 

Channel. Data too meager to determine. 

Discharge measurements. Made from a near-by bridge during high water and

by wading below the mouth of West Elk Creek at ordinary stages. 

Winter flow. Gage heights at this station during the winter months little affected

by ice. 

Diversions. There are court decrees for the diversion of 42 second-feet above the

station and 35 second-feet from the main stream below. 

Accuracy. At the original site the channel was so shifting that no estimates of

discharge are possible. The present site has not been completely rated and no

estimates are available. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

EAST ELK CREEK NEAR NEW CASTLE, COLO.

Location. At the highway bridge on line between sees. 24 and 25, T. 5 S., R. 91 W.,

2£ miles northwest of New Castle, Colo. No tributaries between the station and

the mouth.

Records available. January 19, 1911, to December 31, 1912. 

Drainage area. 60 square miles (measured from Forest Atlas). 

Gage. Vertical staff.

Channel. Permanent prior to high water of 1912, when it shifted. 

Discharge measurements. Made from the bridge during high water and by

wading during ordinary stages. 

Winter flow. Little backwater from ice at this station during the winter except for

short periods. 

Diversions. There are court decrees for diversion of 43 second-feet from East Elk

Creek, chiefly above the station. 

Accuracy. Owing to the very meager gage heights, estimates have not been made

other than for the days having gage heights. These estimates should be reliable

prior to high water, but are somewhat uncertain for the later part of the year,

owing to a shift in the channel. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

been made to determine this.

Diversions. There are court decrees for diversion of 78 second-feet from East River 

above the station and 52 second-feet from tributaries.

Accuracy. Conditions are favorable and therefore the results should be reliable.

CEMENT CREEK NEAR CHESTED BUTTE,, COLO.

Location. At Ahren's ranch, in sec. 22, T. 14 S., B. 85 W., about 7 miles southeast

of Crested Butte. No tributaries between the station and the mouth. 

Records available. November 23, 1910, to December 31, 1912. 

Drainage area. 32 square miles (measured from Forest Atlas). 

Gage. Vertical staff. 

Channel. Somewhat shifting after high water.
GRAND RIVER BASIN. 149

Discharge measurements. Made by wading except during extreme flood stage,

when they are made from a footbridge. 

Winter flow. Ice causes little if any backwater at this station, owing to hot springs

above. 

Diversions. There are court decrees for diversions of 8.5 second-feet from Cement

Creek above the station. 

Accuracy. Estimates for periods prior to the high water are considered reliable;

after that period, when a shift occurred, they were obtained by the indirect

method and are only fair. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

QUARTZ CREEK NEAR PITKIN, COLO.

Location. On highway bridge in sec. 8, T. 50 N., R. 4 E., New Mexico principal 

meridian, 1 mile southwest of Pitkin. Nearest tributary enters about 2 miles 

below the station.

Records available. December 12, 1910, to December 31, 1912.

Drainage area. 53 square miles (measured from Forest Atlas).
GRAND RIVER BASIN, 151

Gage. Vertical staff.

Channel. Apparently permanent.

Discharge measurements. Made by wading.

Winter flow. Ice causes little if any backwater at this station.

Diversions. No water is diverted above the station. Below the station there are

court decrees for 30 second-feet. 

Accuracy. Owing to the high altitude of the drainage basin, alternate melting and

freezing may cause diurnal fluctuations in stage at certain seasons; therefore the

mean daily stage as determined from one reading may be considerably in error.

For this reason the estimates can not be considered better than fair or, possibly,

good.

Channel. Shifting after high water.

Discharge measurements. Made from bridge during high water and by wading

at ordinary stages.

Winter flow. Ice causes backwater during the winter months. 

Diversions. Water sufficient to irrigate approximately 300 acres is diverted above

the station. 

Accuracy. Owing to the shifting channel and the infrequency of gage heights and

measurements the estimates can not be considered better than approximate or fair. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

UNCOMPAHGRE RIVER AT OUR AY, COLO.

Location. Near highway bridge in sec. 31, T. 44 N., R. 7 W. New Mexico principal 

meridian, half a mile south of Ouray, Colo. Nearest tributary, Canon Creek, 

enters 150 feet below; nearest tributary above is Bear Creek.

Records available. January 25, 1911, to December 31, 1912. January 7 to March 

17,1908, records were kept at the power plant of the Ouray Electric Light & Power 

Co., 1 mile south of Ouray, and were furnished through the courtesy of Wheeler 

& Whinnerah.

Drainage area. 44 square miles (measured on topographic sheet).

Gage. Vertical staff.

Channel. Permanent except at time of high water, when channel scours and fills.
GRAND RIVER BASIN- 155

Discharge measurements. Made from bridge during high water and by wading

at ordinary stages. 

Winter flow. Little if any backwater from ice at this station, as channel remains

open during the year. 

Diversions. Water is diverted 2 miles above the station by the Ouray Light & Power

Co. This amounts approximately to 8 second-feet and is returned to the river

below the station. 

Accuracy. Owing to the high altitude of the drainage basin, alternate melting and

freezing may cause diurnal fluctuations in stage at certain seasons. Therefore the

mean daily stage as determined from one reading may be considerably in error.

For this reason the estimates can not be considered better than fair or, possibly,

good. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

UNCOMPAHGRE RIVER AT MONTROSE, COLO.

Location. At highway bridge, one-fourth mile west of Montrose. 

tributary, Happy Canyon Creek, enters about 2 miles below. 

Records available. April 22, 1903, to September 30, 1912. 

Drainage area. 565 square miles. 

Gage. Vertical staff; location and datum unchanged. 

Channel. Extremely shifting. 

Discharge measurements. Made from the bridge.

Nearest important
GRAND EIVEE BASIN. 157

Winter flow. Although ice forms along the edges of the river during the winter 

months the river does not freeze over. Observations of gage heights are, however, 

discontinued during November, December, January, February, and March.

Diversions. Uncompahgre River is so over-appropriated that the United States 

Reclamation Service is constructing a tunnel and canal to divert 1,300 secondfeet from Gunnison River into the Uncompahgre above Uncompahgre.

Accuracy. Although the channel is extremely shifting, sufficient discharge measurements were made during 1912 to afford data for estimates by the indirect method, 

and these estimates may be considered reliable.

Cooperation. Station maintained in cooperation with the United States Reclamation Service, by which the field data are furnished.

UNCOMPAHGRE RIVER NEAR DELTA, COLO.

Location. At highway bridge on township line between Tps. 95 and 96, 2 miles 

south of Delta; no tributaries between the station and the mouth and no important 

tributaries for several miles upstream.

Records available. April 29, 1903, to September 30, 1912.

Drainage area. 1, 130 square miles.

Gage. Vertical staff. The gage was originally located at a highway bridge onefourth mile above the Denver & Rio Grande Railroad bridge. On November 17, 

1903, it was moved to the railroad bridge, where it was read until April 21, 1904. 

An inclined gage was installed near the bridge on April 21, 1904, which was used 

until November, 1906, when a staff gage was installed at the present site. April 

16,1910, a new gage was installed at a datum slightly different from the preceding. 

The relation between the gages at the various sites was not determined.

Channel. Extremely shifting.

Discharge measurements. Made from the bridge.

Winter flow. The flow is probably not materially affected by ice, although ice 

forms along the edges and slush ice frequently occurs. Observations are discontinued during the winter months.

Diversions. The normal flow is diverted during the irrigation season by ditches 

above the station, so that the records represent largely return seepage water.

Accuracy. Estimates only fair or, for certain periods, possibly good, measurements 

being insufficient to permit use of indirect method for shifting channels to fullest 

extent.

Cooperation. Station maintained in cooperation with the United States Reclamation Service, which furnishes the field data.

CANYON CREEK AT OURAY, COLO.

Location. At Ouray, Colo., in sec. 31, T. 44 N., R. 7 W., New Mexico principal 

meridian, in the Uncompahgre National Forest, 200 feet above the mouth of the 

creek. Nearest tributary, a small stream, enters from the east some distance 

above.

Records available. January 25, 1911, to December 31, 1912.
160 SURFACE WATER SUPPLY, 1912, PART IX.

Drainage area. 26 square miles (measured on topographic sheets).

Gage. Vertical staff.

Channel. Shifting.

Discharge measurements. Made from near-by footbridge during highwater and

by wading at ordinary stages.

Winter flow. Ice causes practically no backwater at this station. 

Diversions. No water is diverted above the station, so the records represent the

natural run-off. 

Accuracy. Owing to the high altitude of the drainage basin, alternate melting and

freezing causes diurnal fluctuations of stage at certain seasons. Therefore the

mean daily stage as determined from one reading may be considerably in error.

For this reason the estimates of discharge, in general, can not be considered better

than fair. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

FREMONT RIVER BASIN. 

FREMONT RIVER NEAR THURBER, UTAH.

Location. In sec. 6, T. 29 S., R. 4 E., Salt Lake Meridian, at the ranch of John Smith 

2 miles be!6w the town of Thurber.

Records available. May 13, 1909, to December 31, 1912, when station was discontinued.

Drainage area. 720 square miles.

Gage. Vertical staff.

Channel. Shifts during high water.
166 SURFACE WATER SUPPLY, 1912, PART 1X1

Discharge measurements. Made by wading at low stages and from a cable and

car during high stages. 

Winter records. Ice affects relation of gage height to discharge at times during the

winter months. 

Diversions. Nearly all of the low-water flow of the river above Thurber is diverted

and used for irrigation, most of the water in the channel at such periods being

derived from springs southwest of Thurber. Mill ditch and the Torrey Canal

head about 500 feet below the station. 

Artificial regulation. The flow of the river is regulated by Johnson Reservoir

(capacity, 4,800 acre-feet), which is located about 4 miles north of Fish Lake, the

source of Fremont River. 

Accuracy. Records approximate at times, owing to shifting of the stream bed and

possible backwater at gage from dam below.

NOTE. Relation of gage height to discharge probably slightly affected by ice Jan. 1 to Feb. 29 and Nov. 

22 to Dec. 31. Water over top of gage (7.0) during period Apr. 9 to 12. Gage height on Apr. 10 estimated 

by observer. During period May 12 to 20 the stream bed washed so badly that the water fell below the 

bottom of the gage, the recorded gage heights being estimated by the observer from observations of the 

water level one-fourth mile upstream. Diversion dam rebuilt below the gage May 20.

Sept. 1 to Nov. 20, the other May 21 to Aug. 21. Indirect method for shifting channels used May 12 to 20 and 

Aug. 22 to 31. Discharge estimated Apr. 9,11, and 12 because water was over gage and Nov. 22 to 30 because 

of ice. Daily discharge May 12 to about June 25 approximate, owing to shifting stream bed and possible 

backwater effect from dam below.

MUDDY CREEK NEAR EMERY, UTAH.

Location. In the NE. \ NE. J sec. 21, T. 21 S., R. 6 E., Salt Lake base and meridian, 

at Jacobsen's ranch, about 1 mile above the boundary line of the Manti National 

Forest and about 6 miles from Emery.

Records available. May 1 to July 31, 1909; July 23, 1910, to December 31, 1912.
168 SURFACE WATER SUPPLY, 1912, PART IX.

Drainage area. 87 square miles.

Gage. Inclined staff.

Channel. Shifting.

Discharge measurements. Made from cable during high water and by wading

during low and medium, stages. 

Winter flow. Ice affects relation of gage height to discharge for long periods during

the winter months. Estimates of winter flow are approximate only. 

Diversions. The station is located above the head gates of the Emery, Independence

Co., and Lower canals. It is near a proposed reservoir site. Records indicate

the natural flow of the stream at this point and the amount of water available for

storage in the above-mentioned reservoir. 

Accuracy. Fair during the open-water season of 1912.

NOTE. Discharge determined from several rather poorly defined curves and indirect method for shifting 

channels. Discharge for days on which gage was not read estimated from records at upper station. Gage 

heights at this station give no indication of the floods that occurred at the upper station July 21 and 28, 

probably because the observer read the gages at different times of day.

ESCALANTE RIVER BASIN.

ESCALANTE CREEK NEAR ESCALANTE, UTAH.

Location. In sec. 9, T. 35 S., R. 3 E., Salt Lake meridian, just below the mouth of

Winslow or Pine Creek and about 2 miles below the town of Eecalante. 

Records available. August 5, 1909, to December 31, 1912.
172 SURFACE WATER SUPPLY, 1912, PART IX.

Drainage area. 315 square miles.

Gage. Vertical staff.

Channel. Shifting.

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

Winter flow. Ice affects the relation of gage height to discharge for periods during

the winter months. 

Diversions. All the low-water flow is used for irrigation above the station; the

records at this point indicate unappropriated and waste waters. 

Floods. This stream is subject to sudden floods of short duration, with resulting

changes in the character of the stream bed and control. 

Accuracy. Poor, owing to shifting character of stream bed and lack of discharge

measurements. Yearly total is probably correct within an accuracy of C, but

daily discharge and monthly means during certain periods are apt to be in error

by a greater amount than this.

SAN JTJAN RIVER BASIN. 

SAN JUAN EIVER AT PAGOSA SPRINGS, COLO.

Location. At Pagosa Springs, in sec. 13, T. 35 N., R 2 W., New Mexico principal 

meridian. Nearest tributary is a stream that enters from the north a mile below.

Records available. January 24, 1911, to June 30,1912.

Drainage area. 287 square miles (measured from Forest Atlas).

Gage. Vertical staff. The gage was originally located at a highway bridge above 

Pagosa Springs. On March 7, 1911, the gage was moved half a mile downstream. 

It was washed out by a flood October 5,1911, and a new gage installed November 

23 at the present site. The relation between datums of the different gages is not 

known.
174 SURFACE WATER SUPPLY, 1912, PART IX.

Channel. Apparently permanent.

Discharge measurements. Made from near-by bridge during high water and by 

wading at ordinary stages.

Winter flow. Ice causes backwater at this station for short periods.

Diversions. Small irrigation ditches divert water above the station. Between 

sec. 17, T. 37 N., R. 1 E., and sec. 28, T. 36 N., R. 2 W., there are seven ditches 

averaging 2 feet wide on top, 1£ feet on bottom, and l£ feet deep. There are 

court decrees for diversions of 20 second-feet above the station and 175 secondfeet from tributaries entering above.

Accuracy. Conditions are favorable for fairly accurate results; the estimates are 

considered reliable.

Cooperation. Station is maintained in cooperation with the United States Forest 

Service.

SAN JUAN RIVER AT ARBOLES, COLO.

Location. At Arboles, Colo., a quarter of a mile above the mouth of Piedra River, 

near the center oi T. 32 N., R. 5 W.

Records available. 1895 to 1899; August 21, 1910, to December 31, 1912.

Drainage area. 1,394 square miles.

Gage. Chain gage.

Channel. Probably permanent.

Discharge measurements. Made from car and cable and by wading.

Winter flow. Severe ice effect.

Diversions. There are court decrees for the diversion of 23 second-feet between 

Arboles and the station at Pagosa Springs, and 61 second-feet from intervening 

tributaries.

Flood discharge. Two severe floods have occurred on the San Juan since the 

station has been maintained. The maximum stage of the flood, September 6, 

1909, although very high, was less than that of October 1, 1911, when the river 

rose 17 'feet, with a maximum discharge of about 40,000 second-feet.

Cooperation. Records from August 21, 1910, to October 1, 1912, were furnished by 

the State engineer of Colorado, by whom the station was maintained. After that 

date the station was maintained in cooperation with the State engineers of Colorado and New Mexico.

Location. In sec. 17, T. 29 N., R. 13 W., half a mile southwest of Farmington, at

an old bridge site near Bentleys Ferry, 1,500 feet below the confluence of the San

Juan and Animas rivers.

Records available. September 19, 1912, to December 31, 1912. 

Drainage area. Not measured. 

Gage. Vertical staff. 

Channel. Shifting. 

Discharge measurements. By wading at low stages and from cable at high and

medium stages.

Winter flow. Little affected by ice.

Diversions. Considerable water is diverted for irrigation above this station. 

Accuracy. Because of the shifting character of the stream daily estimates of the

discharge can be considered only fair.

182 SURFACE WATER SUPPLY, 1912, PART IX.

PIEDRA RIVER AT PIEDRA, COLO.

Location. At Piedra post office, Colo., in sec. 8, T. 34 N., R. 4 W. New Mexico principal meridian, in the San Juan National Forest. Nearest tributary, Yellow 

Jacket Creek, enters one-fourth mile below.

Records available. November 26, 1911, to July 22, 1912.

Drainage area. 376 square miles (measured from Hayden's Atlas).

Gage. Vertical staff. On June 8, 1912, a gage reading to a different datum was 

placed on bridge 100 yards upstream from original gage; the exact relation between 

the two gages was not determined.

Channel. Apparently permanent.

Discharge measurements. Made by wading.

Winter flow. Ice causes little if any backwater at this station.

Diversions. A number of small ditches divert water above the station for irrigation.

Accuracy. Sufficient measurements have been made to establish a well-defined 

curve, but owing to infrequency of gage readings monthly estimates have not been 

made.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

188 SURFACE WATER SUPPLY, 1912, PART IX.

ANIMAS RIVEE AT AZTEC, N. HEX.

Location. In eec. 9, T. 30 N., R. 11 W., about half a mile west of Aztec, 200 feet 

upstream from suspension bridge on main wagon road to Farmington and La Plata, 

20 miles above the mouth of the river and below all important tributaries.

Records available. June 21,1904, to December 14,1904; June 8,1907, to December 

31, 1912.

Drainage area. Approximately 1,300 square miles.

Gage. Inclined staff. From June 21, 1904, to September 13, 1908, readings were 

taken from a gage about half a mile downstream from the present gage. Gage 

datum remained unchanged from September 14, 1908, to December 31, 1912. 

The gage was washed out June 1, 1912, and not replaced until September 16, 

1912.

Channel. Subject to shift during high water.

Discharge measurements. Made by wading at low stages and from suspension 

bridge at high stages.

Winter flow. Ice causes slight backwater at times during the winter months.

Diversions. Considerable water is taken out above and below this point for irrigation.

Accuracy. The discharge estimates for the first part of 1912 can be considered only 

fair, but those for the last part of 1912 can be rated as good.

Cooperation. Maintained in cooperation with W. G. Black, Aztec, N. Mex.

HERMOSA CREEK NEAR HERMOSA, COLO.

Location. In sec. 34, T. 37 N., R. 9 W. New Mexico principal meridian, in the San 

Juan National Forest, 1J miles above Hermosa post office, 200 yards below the 

mouth of Buck Creek, 1J miles above the mouth of Hermosa Creek. No tributaries between the station and mouth.

Records available. November 28, 1911, to September 17, 1912.

Drainage area. 172 square miles (measured from topographic sheets).

Gage. Vertical staff.

Channel. Practically permanent.

Discharge measurements. Made from a bridge 1 mile below station during high 

water and by wading at ordinary stages.

Winter flow. So far as known, ice causes little if any backwater at this station.

Diversions. The station is above all diversions.

Accuracy. Owing to infrequency of gage readings, estimates of monthly discharge 

have not been made. Daily discharge for days when gage height was read may 

be considered good for stages below about 1,200 second-feet.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

LA PLATA EIVEK NEAR LA PLATA, N. MEX.

Location. At highway bridge in sec. 14, T. 31 N., K. 13 W., New Mexico principal 

meridian, 18 miles northwest of Aztec, at Williams Ranch house, and 1 mile 

south of La Plata post office. No important tributary between the station and 

the mouth of the river, 15 miles below.

Records available. May 25, 1905, to December 31, 1912.

Drainage area. Approximately 340 square miles.

Gage. Chain gage; on September 15, 1912, the present chain gage was established 

300 feet above the bridge which was washed out in October, 1911. This gage 

was referred to the old datum, but there was 1.2 feet fall in the stream between 

the two points. Gage heights have been corrected to original datum. 

35658° WSP 329 14 13
194 ^SURFACE WATER SUPPLY, 1&12, PART IX.

Channel. Extremely shifting.

Discharge measurements. By wading.

Winter flow. Thin ice frequently forms across the stream during the winter and

thick ice forms along the shore. 

Diversions. Nearly all the normal flow of the river is diverted above the station

during the irrigation season; a few small ditchea take water below. 

Accuracy. Data too meager for estimates of daily discharge.

SANTA CLARA CREEK NEAR CENTRAL, UTAH.

Location. In sec. 14, T. 39 S., R. 16 W., Salt Lake base and meridian, at R. H. 

Hunt's ranch, 6 miles below Pine Valley, and about 1 mile southeast of Central 

post office. Hunts' Spring, which has a fairly constant discharge of about 3 secondfeet, enters just below the station.

Records available. April 21, 1909, to December 31, 1912.

Drainage area. 84 square miles.

Gage. Vertical staff.

Channel. Shifts during flood stages.

Discharge measurements. Made by wading at low stages and from a footbridge 

at high stages.

Winter flow. Ice does not form to any great extent.

Diversions. The Eightmile Flat Canal, which has a maximum capacity of about 

10 second-feet, is the only diversion above the station.

Artificial regulation. None at present. After making allowance for the Eightmile 

Flat Canal, records will indicate the amount of water available for storage in the 

Pine Valley reservoir site.

Accuracy. Records fair except for periods of shifting channels.

SANTA CLARA CREEK NEAR ST. GEORGE, UTAH.

Location. In sec. 27, T. 42 S., R. 16 W., Salt Lake base and meridian, about 2 miles

west of St. George and 3 miles above mouth of creek. 

Records available. April 16, 1909, to December 31, 1912. 

Drainage area. 540 square miles. 

Gage. Inclined staff. 

Channel. Shifting.

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

Winter flow. Ice affects relation of gage height to discharge at times during the

winter months. 

Diversions. The Bloomington and Seep canals divert water from Santa Clara Creek

below the station; except for these canals the records indicate the amount of

unappropriated water flowing from Santa Clara Creek into Virgin River. 

Accuracy. Poor, owing to shifting stream bed, lack of discharge measurements, and

proper gage readings.

The following discharge measurement was made by Leonard Tanner: 

December 12: Gage height, 4.76 feet; discharge, 34.6 second-feet.
VIBGIN EIVEE BASIN. 199

Daily gage height, in feet, of Santa Clara Creek near St. George, Utah, for 1911-12.

NOTE. Daily discharge determined from a number of poorly defined curves and by the indirect method 

for shifting channels. Discharge Mar. 1 to 13,1911, estimated 50 second-feet. Discharge for days on which 

gage was not read estimated by comparison with records at the upper station. Discharge for days when 

depth of water was recorded instead of gage heights determined from a relation of depth to discharge as 

observed on Dec. 9,1912. Discharges obviously approximate.

BILL WILLIAMS RIVER BASIN. 

BILL WILLIAMS RIVER NEAR SWANSEA, ARIZ.

Location. In the canyon, 1 mile below Planet mine, 9 miles northwest of Swansea,

and 28 miles north of Bouse.

Records available. September 26, 1910, to December 31, 1912. 

Drainage area. Not measured. 

Gage. Staff in four sections. The two low-water sections are on right bank a short

distance above cable. Upper sections are bolted to cliffs on left bank just above

cable.

Channel. Shifting sand. 

Diversions. A ranch diverts water for irrigating a few acres about 1 mile above the

station. Desert claims of about 500 acres 20 miles above the station have been

partly irrigated, principally from flood waters. Other small ranches above the

station pump water from the river sands.

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

Data insufficient for estimates of daily and monthly discharge.

GILA RIVER BASIN. 

GILA RIVER NEAR SILVER CITY, N. MEX.

Location. 45 miles northeast of Silver City, 2J miles below Lyon's hunting lodge, 

1 mile below the XSX ranch house, 500 feet below the confluence of East and 

West Forks of the Gila River, in northwestern corner of T. 13 S., R. 13 W.

Records available. June 20, 1912, to December 31, 1912.

Drainage area. Not measured.

Gage. Automatic recording.

Channel. Subject to a shift during high stages.

Discharge measurements. Made by wading at low stages and from cable at high

Winter flow. Practically no backwater from ice during the winter months. 

Diversions. The flow at this point approximates the natural run-off, as there are

practically no diversions above the station.

Accuracy. Estimates of daily discharge in 1912 considered good. 

Cooperation. Maintained in cooperation with Boulware, Johnson & Converse,

Silver City, N. Mex.

GILA RIVER NEAR REDROCK, N. MEX.

Location. About 40 miles west of Silver City, 4 miles northeast of Redrock post 

office, one-fourth mile above the mouth of the box canyon near Connor's ranch, 

near the eastern edge of T. 18 S., R. 18 W. Mancos Draw, the first large tributary 

upstream from the station, joins the Gila about 12 miles above.

Records available. May 14, 1908, to December 31, 1912.

Drainage area. Approximately 3,500 square miles.

Gage. Automatic recording. Records from May 14, 1908, to July 16, 1909, are from 

a gage one-eighth mile downstream from the present gage. The datum of the gage 

has remained unchanged since the gage was installed at the present site on July 

16, 1909.

Channel. Shifting.

Discharge measurements. Wading at low stages and from cable at flood stages.

Winter flow. The relation between the gage height and discharge is not impaired 

by backwater from ice during the winter months.

Diversions. Many diversions for irrigation are made above this station.

Accuracy. Owing to the lack of discharge measurements, daily estimates of the 

discharge were not made for the first part of 1912. The estimates of daily discharge 

for the last part of 1912 can not be considered better than fair.

NOTE. High water of July 24 and 25,1911, caused a decided scour and estimates of discharge for these 

days are rather uncertain. As no high-water discharge measurements were made during 1912, estimates of 

discharge have not been made for Mar. 11 and 12 and July 23 to 25. Dally discharge estimated Aug. 14 to 26.

GILA RIVER AT KELVIN, ARIZ.

Location. About one-half mile below mouth of Mineral Creek, 1 mile below Kelvin, 1

and 25 miles above Florence.

Records available. January 26, 1911, to December 31, 1912. 

Drainage area. Not measured.

Bay Junction on Arizona & Eastern Railroad.
GILA RIVER BASIN. 209

Gage. The original inclined staff was fastened to basalt ledge on right bank opposite 

observer's home. It was destroyed by the flood of March 8, 1911, and replaced 

by painting the section directly on the rock about 10 feet downstream. On November 23, 1911, an inclined staff for low water was fastened to the rock at the same 

location as first gage. On September 20, 1912, an auxiliary vertical staff for low 

water was installed on left bank opposite gage. Original datum has been maintained.

Channel. Sand and somewhat shifting.

Discharge measurements. Made from public car and cable about three-fourths 

mile above gage or by wading.

Diversions. See Gila River at Guthrie.

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

NOTE. Daily discharge 1911-12 computed from several rating curves which are fairly well defined. 

Discharges have not been computed for period June 1 to July 25, as this period is not covered by measurement, and it appears that the nigh water of June 14,1911, scoured out the low-water channel. No highwater measurements were secured during 1912, therefore above stages of 8 feet discharge are rath,er uncertain.

SAN FRANCISCO RIVER NEAR ALMA, N. MEX.

Location. 1£ miles south of Alma, about 90 miles northwest of Silver City, 5 miles

northwest of Glenwood, at the mouth of the box canyon, 4£ miles above the

mouth of Whitewater Creek, and about 1J miles below the mouth of Mineral

Creek, in sec. 4, T. 11 S., E. 20 W.

Records available. August 11, 1912, to December 31,1912. 

Drainage area. Not measured. 

Gage. Vertical staff. The present gage bears no relation to the datum and location

of the gages previously used at the station 1 mile upstream.

Channel. Fairly permanent at low stages but subject to shift during the flood stages. 

Discharge measurements. By wading at low water and from a cable during high

stages.

Winter flow. Practically no backwater from ice during the winter months. 

Diversions. Some water is diverted for irrigation above this station. 

Accuracy. Because of lack of high-water measurements, estimates of the daily

discharge were not made. Estimates of daily discharge will be made at a later

date, when high-water measurements become available.

SAN FRANCISCO RIVER AT DAM ABOVE CLIFTON, ARIZ.

Location. At Arizona Copper Co.'s diversion dam, 1£ miles above Clifton and about 

6£ miles above junction with Gila River.

Records available. January 16, 1911, to June 29, 1912 (incomplete).

Drainage area. Not measured. .

Gage. Original gage was a vertical staff in two sections bolted to upstreaufface of 

dam and right abutment. On November 13, 1911, the upper section was painted 

on inclined crest of dam and on vertical face of right abutment near vertical staff 

damaged by high water. Original datum has been maintained.

Channel. Sand and gravel; somewhat shifting. Dam acts as a partial control, but 

record is affected by the accumulation of sand at intake of canal on right bank.

Discharge measurements. Made from highway bridge at Clifton or by wading.

Diversions. A small amount of water is used for irrigation one-fourth mile above 

dam. At the dam 12 to 14 second-feet are diverted for use in power development 

at Arizona Copper Co.'s smelter. This water is returned to the river above the 

station at Clifton.

Accuracy. Estimates have been prepared from rating curves covering short periods 

and by indirect method for shifting channels. Results are fair.

SAN PEDRO RIVER NEAR FAIRBANK, ARIZ.

Location. At Boquillas diversion dam, in southern part of San Juan de IOB Boquillas

grant, about 2J miles above Fairbank.

Records available. November 15, 1911, to September 28, 1912. 

Drainage area. Not measured. 

Gage. Painted on vertical face of wing wall at left end of dam. Auxiliary gages

were also placed in the canals and wasteways at each end of the dam. 

Channel. Shifting sand above and below dam.
GILA BIVEE BASIN. 219-

Discharge measurements. Made from suspension footbridge 600 feet below dam

or by wading. 

Diversions. Some water is used for irrigation above Charleston. Nearly the entire

low-water flow is diverted at the dam for irrigation on Boquillas ranch.

On account of the many changes in conditions at this station, due to placing and 

removing sand bags on crest of dam and adjustment of wasteways, it is impracticable 

to prepare estimates, and discharge measurements only are published.

Discharge measurements of San Pedro River and of canals and sluices near Fairbarik, Ariz.,

in 1912.

GILA RIVER BASIN. 229

AGUA FRIA RIVER NEAR GLENDALE, ARIZ.

Location. At old diversion dam of the Beardsley irrigation project at Camp Dyer, 

in sec. 28, T. 6 N., R. 1 E., 4 miles below mouth of Castle Creek, and 22 miles 

northwest of Glendale.

Records available. November 10, 1910, to December 31, 1912.

Drainage area. Not measured.

Gage. The diversion dam failed during the flood of 1895, when a portion of the 

masonry near each end was washed out. At low and medium stages the entire 

stream flows through the larger opening, which is near the right bank. The gage 

for each channel is painted on upstream face of dam at right of opening. On September 18, 1912, a vertical staff for low water was installed on upstream face of 

dam at the left of right opening.

Channel. Sand, and shifting.

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

Accuracy. Full reliance can not be placed in the gage-height records observed by 

watchman at the dam. Data insufficient for estimates of daily and monthly 

discharge.

Cooperation. Gage-height record furnished by Beardsley Irrigation Co., through 

A. L. Harris, engineer.

NOTE. Stream was dry July 1 to 20, Aug. 5 to 11,22 to 23, Sept. 4 to 29, and Oct. 6. No records obtained 

after Oct. 6. Mean gage heights for Aug. 30,31, and Sept. 30 were determined from graphs based on several 

additional readings. Maximum observed height Aug. 30 was 9.3 feet at 6.30 a. m.; same for Sept. 30 was 

11.5 feet at 6.30 a. m.

Daily discharges computed from a rating curve which is well defined between 120 and 1,400 second-feet, 

and fairly well defined between 8 and 120 second-feet. Maximum discharge Aug. 30, 1,120 second-feet; 

Sept. 30, 2,060 second-feet.
