o 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.

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 reportsiipon the best methods of utilizing the water resources.

Annual appropriations for the fiscal year ending June 30:

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

8 SURFACE WATEE SUPPLY, 1911, PART IX.

In the execution of the work various private and State organizations have cooperated. Acknowledgments for such cooperation are 

made on page 15, and also in connection with the description of 

each station affected by the cooperative work.

PUBMCATIONS.

Measurements of stream flow have been made at more than 2,000 

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

in Seward Peninsula and the Yukon-Tanana region, Alaska, and in 

the Hawaiian Islands. During 1911 gaging stations were maintained 

by the Survey and the cooperating organizations at about 1,500 

points in the United States, 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 surface water-supply papers 

from time to time. A complete list of the gaging stations maintained 

by the Survey to and including 1910 and a list of the papers relating 

to the water supply of the country has been published by the Survey 

as Water-Supply Paper 280. An index to the reports containing 

stream-flow measurements prior to 1904 has been published as WaterSupply Paper 119.

For each calendar year there has been prepared a report embodying 

the stream-flow data collected during that year, which has been published either as a part of the annual report of the Director, as a bulletin, or as a water-supply paper, as shown by the following table:

DEFINITION OF TERMS.

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

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

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

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

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

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

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

follows:

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

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

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

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

of the factors given in the following table of equivalents.

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

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

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

regards time and area.

" Eun-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.

EXPLANATION OF DATA.

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

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

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

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

In addition to statements regarding the location and installation 

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

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

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

channels, and backwater; also information regarding diversions 

which decrease the total flow at the measuring section. Statements 

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

The 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

EXPLANATION OF DATA. 13

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 J>e determined from the tables of daily gage 

heights and daily discharge, as follows:

First plot the discharge measurements for the current and earlier 

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

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

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

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

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

curve used and will lie among the plotted discharge measurements. 

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

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

These values should be so adjusted that the first differences shall 

always be increasing or constant, except for known backwater 

periods.

The table of daily 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 at " 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 secondduring the month. On this the computations for the remaining columns, which are defined on page 10, are based.

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

this series of reports are described in the introductory sections of 

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

the United States, 1909." Plates I and II show the average precipitation and run-off in the United States as determined from the

records of rainfall collected by the Weather Bureau; Plate III 

shows typical gaging stations, indicating the method of suspending 

the current meter; Plate IV shows current meters* used in the work.

ACCURACY AND RELIABILITY OF FIELD DATA AND 

COMPARATIVE RESULTS.

The accuracy of steam-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 noncontributing districts or 

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

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

as a rule not feasible to make adequate correction.

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

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

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

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

The determinations of daily discharge allow more detailed studies of 

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

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

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

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

COOPERATION AND ASSISTANCE.

GREEN RIVER NEAR ELGIN, 1 UTAH.

Location. At the highway bridge 200 feet upstream from the Denver & Rio Grande 

Railroad bridge at Green River railroad station near Elgin, Utah, in sec. 15, T. 21 

S., R. 16 E., Salt Lake base and meridian.

Becords available. October 21, 1894, to October 15, 1899; February, 1905, to 

December 31,1911.

Drainage area. 38,200 square miles.

Gage. Chain gage attached to bridge.

Channel. Somewhat shifting; divided by the highway bridge into three sections, 

each 168 feet wide.

Discharge measurements. Formerly made from the railroad bridge and from a 

near-by ferry; now they may be made from the highway bridge, where measuring 

conditions are very favorable.

Winter flow. Ice usually exists at the station during December, January, and February, and affects the relation of gage height to discharge.

Diversions. The gaging station is located below all important diversions.

Accuracy. Fair only, owing to shifting character of stream bed.

Cooperation. Maintained in cooperation with the State of Utah.

i Described in the earlier reports as near "Blake." The name of the post office was later changed to Elgin.

and Dec. 10-20 were computed from a study of records at Elgin and the Little Valley stations. The gage 

heights given are the means of the gage heights for the periods at Elgin station, and the discharges are the 

means of the computed discharges at the Little Valley station for the same periods, except that the means 

of the computed discharge for the periods Sept. 18-26 and Nov. 8-12 were used in obtaining mean discharges 

for the gage-height periods at Elgin.

NOTE. Daily discharge determined as follows: Jan. 1-10, estimated 1,200 second-feet; Jan. 11-16, estimated 2,600 second-feet; Jan. 17 to June 20, and Dec. 21 to Dec. 31, from a well-defined curve; June 21 

to July 31 from a fairly well-defined curve; Aug. 1 to Dec. 20 by indirect method for shifting channels. 

Thecurves are partly denned by study of discharge data at Little Valley (7 miles below Elgin) during 1911.

GREEN RIVER AT LITTLE VALLEY, NEAR GREEN RIVER, UTAH.

Location. At Little Valley Ferry, 4 miles downstream from Green River railroad 

station (7 miles by wagon road) in sec. 5, T. 22 S., E. 16 E., Salt Lake meridian. 

Records available. December 18,1910, to December 31,1911. 

Drainage area. Not accurately known.
22 SURFACE WATER SUPPLY, 1911, PART IX.

Gage. Staff, in four sections three inclined and one vertical.

Channel. Shifts at measuring section; fairly permanent at control.

Discharge measurements. Made from car on ferry cable.

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

months of December, January, and February.

Diversions. Below all important diversions.

Accuracy. Gage height data for 1911 are unreliable for first three months and 

fragmentary for the rest of the year. For this reason and as there is a complete 

and reliable record available at Elgin (only 6 miles by river above Little Valley) 

no estimates are published for 1911. Engineers and others interested are referred 

to the record at the Elgin station for 1911.

Cooperation. Maintained in cooperation with the State of Utah.

River.

Records available. April 1, 1878, to December 31, 1911. 

Drainage area. 225,000 square miles. 

Gage. Vertical staff in two sections at the bridge; the zero of the gage is 102.79 feet

above sea level. 

Channel. Shifting sand.

Discharge measurements. Made from car and cable 600 feet below the gage. 

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

station.

Accuracy. Results are considered good. 

Cooperation. Complete record is furnished by the United States Reclamation

Service through F. L. Sellew, project engineer.

TRIBUTARY BASINS.

NEW FORK RIVER BASIN. 

NEW FORK KIVEK NEAR CORA, WTO.

Location. At Alexander's ranch in sec. 29, T. 36 N., K. 110 W., 3J miles below the 

outlet of New Fork Lake and 10 miles northwest of Cora post office.

Records available. July 29, 1910, to September 30, 1911. From May 23 to August 

31, 1905, a station described under the same name was maintained 12 miles below 

the present site. The records at the two points are not comparable, as several 

tributaries enter between and several diversions are made.

Drainage area. Not measured.

Gage. Vertical staff; datum was raised 7.12 feet September 23, 1910; all readings 

refer to the present datum.

Channel. Data too meager to determine.

Discharge measurements. Made by wading.

Diversions and storage. The natural storage afforded by New Fork Lake and other 

lakes in the basin gives the New Fork a fairly uniform flow. New Fork Lake will 

probably be used for storage in connection with irrigation. Only one small ditch 

takes out above the station.

Winter flow. Ice causes backwater during the winter months.

Accuracy. Owing to insufficient data no estimates of discharge are available.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

NOTE. From Jan. 1 to Apr. 10 gage heights were affected by ice; average thickness of ice in January, 12. 

feet; in February, 1.2 feet; in March, 0.9 foot; from Apr. 1 to 10,0.6 foot.

PINE CKEEK NEAR PINEDALE, WYO.

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

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

Records available. July 22, 1910, to December 16, 1911. From April 2, 1905, to 

October 31, 1906, a station described under the same name was maintained onehalf mile below the present station. The records at the two points are not comparable, as two ditches divert water between the two.

Drainage area. 130 square miles (measured from Land Office map).

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 gives Pine Creek a fairly 

uniform flow.

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

Accuracy. On account of the scattering gage heights the records can not be considered better than fair.

Winter flow. Ice causes backwater at the station, and the records are discontinued 

during the winter months.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

BIG SANDY CHEEK; BASIN.

BIG SANDY CREEK NEAR BIG SANDY, WYO.

Location. At Leckie's ranch, in sec. 18, T. 30 N., R. 104 W., about 4 miles east of 

Big Sandy post office, Wyo.; below all mountain tributaries.

Records available. July 26, 1910, to August 31, 1911.

Drainage area. Not measured.

Gage. Chain gage installed September 27, 1910. All data for 1910 derived from 

readings on a staff gage referred to a different datum.

Channel. Apparently permanent.

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

wading at ordinary stages.

Diversions and storage. The Eden Irrigation Co., which has a project in T. 26 N., 

R. 105 W., is building a reservoir at the present gaging station site. Prior to July 

1, 1912, there were adjudicated diversions from Big Sandy River of 37 secondfeet. It is not known what portion of this is above the station.

Accuracy. Owing to the meager data the records can not be considered better than 

fair.

Cooperation. Station maintained in cooperation with the United States Foreet 

Service.

ASHLEY CHEEK BASIN. 

ASHLEY CHEEK NEAR VEKNAL, UTAH.

Location. In see. 13, T. 3 S., R. 20 E., Salt Lake base and meridian, about 1 mile

below the Ashley Creek power plant and about 15 miles north of Vernal, Utah;

2£ miles above the mouth of Dry Fork. 

Records available. March 18, 1900, to December 31, 1904, at a point below the

mouth of Dry Fork; October 8, 1911, to December 31, 1911, at present site. 

Drainage area. 107 square miles. 

Gage. Vertical staff on the right bank. 

Channel. Shifting.

Discharge measurements. Made by wading. 

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

part of the winter months. 

Diversions. Above all diversions. 

Artificial control. The operation of the power plant probably has no effect on the

flow at the station. 

Accuracy. Poor, because of lack of discharge measurements. As only one discharge

measurement was made during 1911 and one in 1912 (taken at the same gage height

as the 1911 measurement) a rating curve can not be constructed. 

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

The following discharge measurement was made by E. C. La Rue: 

October 8, 1911: Gage height, 1.68 feet; discharge, 108 second-feet.

Daily gage height, in feet, and discharge, in second-feet, of Ashley Creek near Vernal,

Utah, Jor 1911.

LAKE FORK CREEK NEAR MYTON, UTAH.

Location. About 100 yards below a county highway bridge in sec. 21, T. 3 S., E.

2 W., Uinta special base and meridian, 3 miles above Myton, Utah, about half a

mile above the junction of Lake Fork Creek and Duchesne River. 

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

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

Drainage area. Not measured. 

Gage. Chain gage. Several different gages and datums have been used previous to

1910. See Water-Supply Paper 289. The datum used in 1911 Is 0.03 feet lower

than that in 1910. 

Channel. Fairly permanent.

Discharge measurements. Made from car and cable 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 some privately

owned canals take water from this stream above the station for irrigation. 

Accuracy. Excellent. 

Cooperation. Maintained in cooperation with the State of Utah.

WHITE RIVER BASIN. 

NORTH FORK OF WHITE RIVER NEAR BTJFORD, COLO.

Location. At Genier's ranch, 1J miles above Buford, about sec. 3, T. 1 S., R. 91 W. 

No important tributary enters between the station and the mouth of the South 

Fork.

Records available. -May 24, 1910, to December 31, 1911. From July 18, 1903, to 

October 31,1906, a gaging station was maintained by the United States Geological 

Survey just below Ute Creek, 5 miles above the present station. The records at 

the two points are very nearly comparable, as no important tributaries enter 

between.

Drainage area. 240 square miles (State engineer's report).

Gage. Vertical staff.

Channel. Practically permanent.

Discharge measurements. Made from footbridge.

Diversions. There is a court decree for a diversion of 1.6 second-feet from the North 

Fork above the station, but none below. There are decrees for diversions of 33 

second-feet from tributaries entering above.

Cooperation. Station is maintained and records are furnished complete for publication by the State engineer.

PRICE RIVER AT WOODSIDE, UTAH.

Location. At the Denver & Rio Grande Railroad bridge crossing Price River at 

Woodside, in sees. 9 and 16, T. 18 S, R. 14 E., Salt Lake base and meridian, about 

8 miles below a proposed diversion dam for an irrigation project, and about 15 

miles above the junction with Green River.

Records available. October 1, 1909, to December 31, 1911.

Drainage area. 1,500 square miles.

Gage. Distance from a fixed point on the bridge to water surface is measured daily.

Channel. Composed largely of quicksand.

Diversions. A few small tributaries enter Price River between the dam site and the 

station.

Discharge measurements. Made from upper side of railroad bridge.

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

the winter months.

Accuracy. Because of the shifting character of the stream bed and as only two measurements were made during 1911, estimates of daily and monthly discharge can 

not be made.

Cooperation. Data for this station supplied by Mr. Horace W. Sheley, consulting 

engineer, Salt Lake City, Utah. The location of station and methods of collecting 

data and making estimates have been approved by the United States Geological 

Survey.

HUNTINGTON CREEK NEAR HUNTINGTON, UTAH.

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, 1911. 

Drainage area. 158 square miles. 

Gage. Vertical staff in two sections. 

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. 

Point of zero now. On September 4 it was determined that there would be no

flow past the station if the stage were to fall below about 1.5 feet. Control will

change. 

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

months.

Diversions. Above all diversions (except Cunha's ditch) and below all main tributaries. 

Artificial control. A small storage reservoir on Huntington Creek above the station

COTTONWOOD CREEK NEAR ORANGEVILLE, UTAH.

Location. At Johnson's ranch, in sec. 9 or 10, T. 18 S., R. 7 E., Salt Lake base and

meridian, about 5 miles northwest of Orangeville. 

Records available. May 1, 1909, to December 31, 1911. 

Drainage area. 240 square miles. 

Gage. Inclined staff. 

Channel. Shifting. 

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

car at high stages.

Floods. Short, severe floods occur at this station during August and September. 

Point of zero flow. On August 22, 1911, it was determined that there would be no

flow past the gage if the stage were to fall below about 3 feet. Control will change. 

Winter flow. Relation of gage height to discharge affected by ice at times during

FEKRON CHEEK (UPPEE, STATION) NEAE, FEKRON, UTAH.

Location. At the Peterson (formerly Christensen's) ranch, in sec. 35, T. 19 S., R. 6

E., Salt Lake base and meridian, about 5 miles northwest of Perron and 1J miles

above the flour mill.

Records available. May 6 to December 31, 1911. 

Drainage area. Not measured. 

Gage. Vertical staff and sloping gage. New sloping gage installed September 13,

1911,150 feet below the staff, was used for records after that date. 

Channel. Probably shifts at high stages.

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

Point of zero flow. On September 13 and October 8 it was determined that there

would be no flow past the station if the stage were to fall below about 1 foot on

the sloping gage. Control will probably change. 

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

the winter months. 

Diversions. Above all diversions. 

Accuracy. Fair. 

Cooperation. Maintained in cooperation with the State of Utah.

FEERON CREEK NEAR FEREON, UTAH.

Location. At Westenskow's ranch, about half a mile below the headgates of the 

North and South canals, and about 2£ miles above the town of Ferron, Utah; 

probably in sec. 7, T. 20 S., R. 7 E., Salt Lake base and meridian.

Records available. April 28, 1909, to October 7, 1911.

Drainage area. 153 square miles.

Gage. Gage readings are obtained by measuring down to the water surface from a 

fixed point on the footbridge.

Channel. Practically permanent at medium stages.

Discharge measurements. Made from a footbridge at gage during high water and 

by wading at low water.

Point of zero flow. On September 12 it was determined that there would be no 

flow past the station if the stage were to fall below about 4 foot. Control may 

change.

Winter flow. Ice forms at times during winter months.

Diversions. Two large canals, the North and South, with a combined capacity of 100 

second-feet, divert water above the station, and many small ditches take water 

both above and below the station.

Accuracy. The discharge curve is fairly well defined but the estimates can be considered only fair because of diversions made above gage.

Cooperation. Maintained in cooperation with the State of Utah.

FERRON CHEEK NEAR, CASTLEDALE, UTAH.

Location. About 8 miles below the town of Ferron, Utah, and 4 miles south of

Castledale, Utah, at a point known locally as Paradise, in sec. 35, T. 19 S., K.

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, 1911. 

Drainage area. Not measured. > 

Gage. Inclined staff on left bank. 

Channel. Shifting.

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

Point of zero flow. On September 12 it was determined that there would be no

flow past the station if the stage were to fall below about 4.2 feet. Control will

change. 

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

months.

Diversions. Below all diversions, except the Fred Anderson ditch. 

Accuracy. Fair only, because of shifting character of stream bed. 

Cooperation. Maintained in cooperation with the State of Utah.

GRAND RIVER BASEST. 

NORTH FORK OF GRAND RIVER NEAR GRAND LAKE, COLO.

Location. Three miles southwest of Grand Lake, Colo., in sec. 13, T. 3 N., R. 76 W.

Nearest tributary, Grand Lake outlet, enters some distance below; no tributaries

for several miles above the station. 

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

December 31, 1911.

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 estimates of discharge, which have been made only for days when the

gage was read, should be reliable. 

Cooperation. During 1911 the station was maintained in cooperation with the

United States Forest Service and the State engineer.

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 Creek3 enters the river 2 miles below the station.

Records available. July 22,1904, to September 30, 1909; September 23, 1910, to 

December 31, 1911.

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.
96 SURFACE WATER SUPPLY, 1911, PART IX.

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 character of the channel the estimates of discharge 

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

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

Service and the State engineer.

NOTE. Daily discharge determined from a fairly well defined rating curve. Estimates made only for 

days when gage was read.

GRAND RIVER NEAR KREMMLING, COLO.

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

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

Records available. July 24, 1904, to December 31, 1911.

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 freezes entirely across at the station, there was 

little if any backwater during 1911, as shown by discharge measurements made 

during the winter. Rapids below the station remained open and thus prevented 

backwater from ice.

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.

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

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

State engineer.

GRAND RIVER AT GLENWOOD SPRINGS, COLO.

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

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

above Hie station, and Roaring Fork enters one-half mile below.

Records available. May 12, 1899, to December 31, 1911.

Drainage sjrea. 4,520 square miles (measured from Wells map of Colorado).

Gage. Automatic recording gage. Datum unchanged since 1900.

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 flo\ir. Ice never forms at the station, as the hot water from the springs keeps 

the water above the freezing point.
100 STJBFACE WATBE SUPPLY, 1911, PAET IX.

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. Except at high water, when the swiftness of the current makes it difficult

to secure accurate discharge measurements, conditions are favorable for accurate

results, and the records are considered excellent. 

Cooperation. During 1911 the station was maintained in cooperation with the

United States Forest Service and the 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 November 30, 1911.

Drainage area. 8,550 square miles.

Gage. Chain gage; location and datum unchanged.

Channel. Practically permanent.
102 SURFACE WATER SUPPLY, 1911, PART IX.

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 of 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 favor accurate results, and the estimates should be reliable.

Cooperation. During 1911 station was maintained in cooperation with the United 

States Reclamation Service, which furnished most of the field data.

GRAND RIVER NEAR, FRUITA, COLO.

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

Ute 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. May 4, 1911, to November 30, 1911.

Drainage area. 16,800 square miles (measured from Hayden's atlas).
104 SUEFACE WATER SUPPLY, 1911, PART IX.

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

Channel. Apparently permanent, although the data are not sufficient to confirm

this definitely.

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. This station is not completely rated as yet, and estimates of discharge are

not available. The base data p should be reliable. 

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

States Weather Bureau.

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

December 31, 1911. 

Drainage area. 62 square miles (measured from Hay den's Atlas).
GRAND EIVEE BASIN. 107

Gage. Vertical etaff; 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 coming 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 excellent, but on account of the natural regulation of Grand Lake,

the flow is uniform. This uniformity of flow and permanence of channel indicate

that the estimates are good. 

Cooperation. Since its reestablishment in 1910 the station has been maintained in

cooperation with the United States Forest Service and the State engineer.

SURFACE WATER SUPPLY, 1911, PART IX. 109

FRASER RIVER BASIN. 

FRASER RIVER NEAR FRASER, COLO.

Location. Two miles south of Spruce Lodge ranger station, in the Arapahoe National 

Forest, 10 miles from Fraser post office. Current Creek enters 2 miles above the 

station, and Jim Creek 3 miles below.

Records available. May 1, 1908, to September 17, 1911.

Drainage area. Approximately 9 square miles.

Gage. An automatic recording gage installed June 29, 1911. A staff gage was used 

during 1908. July 7, 1909, a second staff gage was installed at a different datum 

which has remained unchanged. The recording gage reads to the same datum 

as the second staff gage.

Channel. Somewhat shifting.

Discharge measurements. Made from a footbridge.

Winter flow. No data.

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

River above the station into Clear Creek on the eastern slope. There is also a 

provisional decree for a similar diversion of 700 second-feet, which has not yet 

been made.

Accuracy. Data insufficient for estimates of discharge.

Cooperation. Station maintained and records furnished through the courtesy of the 

Denver Reservoir Irrigation Co.

The following discharge measurement was made by Stanley Krajicek: 

June 30, 1911: Gage height, 0.91 foot; discharge, 30.8 second-feet.

Daily gage height, in feet, of Fraser River near Fraser, Cola., for 1911.

110 SURFACE WATER SUPPLY, 1911, PART IX.

FRASER RIVER 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 December 31, 1911.

Drainage area. 16 square miles (measured from Forest atlas).

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

Diversions. There are no court decrees for diversions between Fraser and Arrow, 

but below there is a decree for diversion of 72 second-feet from Fraser River.

Accuracy. With the exception of some uncertainty in the records derived from 

application of the upper part of the rating curve the records can be considered 

fair or possibly good.

WILLIAMS FORK BASIN. 

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.

Records available. September 22, 1910, to December 31, 1911.

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. As no winter measurements have been made, it is not known if ice 

causes backwater.

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, estimates of discharge can 

not be made.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

The following discharge measurement was made by H. B. Waha: 

September 14, 1911: Gage height, 1.50 feet; discharge, 91.2 second-feet.

Daily gage height, in feet, of Williams Fork near Scholl, Colo., for 1911.

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 small stream that enters 

from the west 2 miles below the station.

Records available. July 25, 1904, to December 31, 1911.

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

Gage. Vertical staff; location and datum unchanged.

Channel. Shifting after high water.

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 1911 were taken in the afternoon.

Diversions. There are court decrees for the diversion of 502 second-feet from Williams Fork between this station and the one near Scholl, and 25 second-feet from 

tributaries. There is also a storage decree for 80,700 acre-feet from Williams Fork.

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

be reliable.

Cooperation. During 1911 station was maintained in cooperation with the State 

engineer.

BLUE RIVER BASIN. 

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, 1911.

Drainage area. 110 square miles (Forest Service 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 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.

Accuracy. Owing to the high altitude of this station there are liable to be appreciable diurnal fluctuations at certain seasons, due to alternate melting and freezing, 

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 or possibly good.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

TENMILE CREEK AT DILLON, COLO.

Location. At the highway bridge in Dillon, Colo., in eec. 18, T. 5 S., B,. 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 December 31, 1911.

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.

Winter now. 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. As the station has not been completely rated, estimates of discharge can 

not be made.

Cooperation. Station is 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 December 31, 1911.

Drainage area. 92 square miles (Forest Service Atlas.)
120 SUBFACE WATEE SUPPLY, 1911, PAET IX.

Gage. Vertical staff; location and datum unchanged.

Channel. Practically permanent.

Discharge measurements. Made by wading above the bridge.

Winter flow. Ice gorges cause backwater of varying amount. Discharge measurements are made to determine the flow.

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 there are liable to be appreciable diurnal fluctuations at certain seasons, due to alternate melting and freezing, and themeandailygageheightbased on onegage reading maybe considerably 

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

better than fair or possibly good.

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, 1QO yards above mouth of Turkey Creek, and 1 mile above the

mouth of Homestake Creek.

Records available. January 1, 1911, to December 31, 1911. 

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

Gage. Chain gage, location and datum unchanged. 

Channel. Practically permanent. 

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

reliable.

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 December 11, 1911, at

present site.

Drainage area. 580 square miles (measured from Forest atlas). 

Gage. Vertical staff. Referred to the same datum as the Weather Bureau gage

nearby.

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. Owing to the small number of gage heights the records can not be considered better than fair. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

GORE CREEK NEAR MINTURN, COLO.

Location. In sec. 22, T. 5 S., E. 81 W., 200 feet above the mouth of the creek, 1 mile

northwest of Minturn. Nearest tributary, Willow Creek, enters 2 miles above the

station.

Records available. July 15, 1911, to December 31, 1911. 

Drainage area. 98 square miles (measured from Forest atlas). 

Gage. Inclined staff. 

Channel. Apparently permanent. 

Discharge measurements. Made from the railroad bridge near by during high

water and by wading during ordinary stages. 

Winter flow. Ice causes backwater during winter months; discharge measurements

are made to determine the winter flow. 

Diversions. There are court decrees for diversion of 5.7 second-feet from Gore

Creek, and 2.5 second-feet from a tributary entering above. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

BRUSH CREEK 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 1, 1911, to December 31, 1911.

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 some 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. Although gage heights are scattering, good results have been obtained by 

means of comparison with flow at other streams and from climatologic data.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

NO NAME CREEK BASIN. 

NO NAME CREEK NEAR GLENWOOD SPRINGS, COL.O.

Location. In sec. 5, T. 5 S., R. 88 W., 4 miles from Glenwood 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 December 31, 1911.

Drainage area. Not measured.

Gage. Vertical staff.

Channel. Practically permanent.

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

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. As the station has not yet been completely rated, estimates of discharge 

can not be made.

Cooperation. Station maintained in cooperation with the United States Forest 

Service and the Glenwood Light & Water Co.

ROARING FORK BASIN. 

ROARING FORE AT ASPEN, COLO.

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

creeks.

Records available. January 1, 1911, to December 31, 1911.

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

Gage. Vertical staff.

Channel. Practically permanent.

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

are made from bridge near gage.

Winter flow. Ice causes backwater during the winter months, and 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 from the middle of May to the middle of September.

Accuracy. Fairly good results have been obtained at thia station.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

ROARING FORE AT GLENWOOD SPRINGS, COLO.

Location. On bridge 500 feet above the mouth of the river in Glenwood 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 31,1911.

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

Gage. Chain gage; location and datum unchanged. 

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

may cause backwater at the gage.

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, and the estimates should be

reliable. 

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

United States Forest Service.

HUNTER CREEK AT ASPEN, GOLD.

Location. On the railroad bridge in Aspen, in see. 7, T. 10 S., R. 84 W., about 500 

feet above the mouth. No tributary enters within several miles of the mouth.

Records available. February 17 to December 31, 1911.

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

Gage. Vertical staff.

Channel. Shifting after high water.

Discharge measurements. Made by wading.

CASTLE CREEK NEAR ASPEN, COLO.

Location. On the highway bridge 4 miles above Aspen, in sec. 35, T. 10 S., R. 85 W., 

in the Sopris National Forest. No tributary is between the station and the mouth 

of the creek except small gulches that carry spring run-off. Nearest tributary 

above, Conundrum Creek, enters about 6 miles upstream.

Records available. February 16 to December 31, 1911.

Drainage area. 72 square miles (measured from topographic sheets).

Gage. Vertical staff.

Channel. Somewhat shifting.

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; there is a court decree for 2 

second-feet below the station.

Accuracy. As the station has not yet been completely rated estimates of discharge 

can not be made. The base data should be reliable.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

MAROON CREEK NEAR ASPEN, COLO.

Location. In see. 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 Aepen, Oolo.

Nearest tributary, Willow Creek, enters just below the station. 

Records available. January 1 to December 31, 1911. 

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

Gage. Vertical staff. 

Channel. Shifting after high water. 

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

are mule from a footbridge. 

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

at this station. 

Diversions. So far as known, no water is diverted above the station; the Roaring

Fork Light & Power Co. diverts water just below. 

Accuracy. Estimates made are reliable, but snowslides upstream sometimes choke

the channel and hold the water back. 

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., R. 86 W., a 

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

mouth of the creek.

Records available. February 21 to December 31, 1911.

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

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. Chere are also decrees for 

diversions of 73 second-feet from tributaries entering above.

Accuracy. Estimates of discharge are considered fair.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

148 SURFACE WATER SUPPLY, 1911, PART IX.

FRYING PAN CREEK AT THOMASVILLE, COLO.

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

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

Creek, enters 100 yards above.

Records available. January 2 to December 31, 1911.

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 are favorable for accurate results, and the results are 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 Sopris National 

Forest, about 1 mile from Norrie. No tributaries between the station and the 

mouth of the creek.

Records available. February 18 to December 31, 1911.
150 SURFACE WATER SUPPLY, 1911, PART IX.

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

Gage. Vertical staff.

Channel. Permanent.

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

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

Diversions. No water is diverted above the station.

Accuracy. Owing to the scattered gage heights the records can not be considered 

better than fair or possibly good.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

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. The channel at the original site was so unstable that the discharge could

not be computed. The rating for the present site has not been completed. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

WEST DIVIDE CREEK AT RAVEN, COLO.

Location. At Ewer's ranch, three-fourths of a mile north of Raven, Colo., about sec.

13, T. 7 S., R. ^2 W. Nearest tributary, Halls Gulch, enters between the station

and Raven. 

Records available. July 27, 1909, to July 30, 1910, at Raven; September 20, 1910,

to March 31, 1911, at present site. The records at the two stations are practically

comparable, as only Halls Gulch intervenes.

Drainage area. 101 square miles (measured from Hayden's atlas). 

Gage. Vertical staff. 

Channel. Slightly shifting. 

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

during ordinary stages.

Winter flow. Ice causes backwater during a part of the winter period. 

Diversions. There are court decrees for diversions of 174 second-feet from West

Divide Creek above the station, and for 114 second-feet between the station and

the mouth. 

Accuracy. Data insufficient to warrant estimates of discharge.

Daily gage height, in feet, of West Divide Creek at Raven, Colo., for 1911.

Creek, enters about 1 mile below.

Records available. November 27, 1910, to December 31, 1911.

Drainage area. 963 square miles (measured from Hayden's atlas).

Gage. Chain gage.

Channel. Somewhat shifting.

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

at ordinary stages.

Winter flow. Ice causes backwater during the winter months, but no measurements 

have been made to determine the variation in amount.

Diversions. There are court decrees for diversions of 250 second-feet from Gunnison 

River between this station and the forks at Almont, and diversions of 270 secondfeet from intervening tributaries.

Accuracy. Estimates are considered only fair.

Cooperation. Station maintained in cooperation with the State engineer, by whom 

the field data are furnished.

GTTNNISON- RIVER AT RIVER PORTAL, COLO.

Location. About 300 feet above the portal of the Gunnison tunnel of the United 

States Reclamation Service, about sec. 10, T. 49 N., R. 7 W., New Mexico principal 

meridian, 21 miles northeast of Montrose. Nearest tributary, Crystal Creek, enters 

about 4 miles above.

Records available. April 7, 1905, to November 6, 1911. September 18, 1903, to 

December 17, 1905, a station was maintained at Cimarron, about 12 miles above. 

The records at the two points are not directly comparable as Cimarron River and 

Crystal Creek enter between.

Drainage area. 4,140 square miles (measured from Land Office map).

Gage. Staff. The original staff gage, which was bolted to the cliff on the right bank 

of the river, was dislodged by driftwood June 4, 1909; prior to this time there had 

been no change in location or datum. From June 5 to 19 an old high-water gage, 

100 feet upstream, with its datum 10.08 feet lower than that of the original gage, 

was used, and readings were reduced to the original datum. August 9, 1909, a 

new staff gage was installed at the original site and datum. This gage was 

destroyed November 20,1909, but replaced in 1910, by the gage at present in use.

Channel. Slightly shifting. Debris from the Gunnison tunnel is dumped into the 

river below the station.

Discharge measurements. Made from car and cable near the station.

Winter flow. Ice covers the river and records are discontinued for about 4 months 

each year; the ice attains a thickness of 1 to 2 feet.

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

for the diversion of 55 second-feet from the Gunnison and 580 second-feet from the 

intervening tributaries. Just below the station is the entrance of the Gunnison 

tunnel through which 1,300 second-feet will be diverted into TIncompahgre 

Valley.

Accuracy. Although the channel shifts slightly, sufficient measurements have been 

obtained to make the estimates reliable.

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

EAST RIVER AT ALMONT, COLO.

Location. At highway bridge at Almont, 200 feet above the junction of East and

Taylor rivers. 

Becords available. April 15 to October 8, 1905; July 27, 1910, to December 31,

1911.

Drainage area. 295 square miles (measured from Forest atlas). 

Gage. Vertical staff. No determined relation between datum of present gage and

that of gage used in 1905. 

Channel. Practically permanent. 

Discharge measurements. Made from bridge. 

Winter flow. Ice causes backwater during the winter months but no measurements

have been made to determine the variation in amount. 

Diversions. There are court decrees for 78 second-feet from Eas_t River above the

station, and 52 second-feet from tributaries. 

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

reliable.

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

BASIN. 169

CEMENT GREEK NEAR CRESTED BTTTTE, COLO.

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

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

Records available. November 23, 1910, to December 14, 1911. 

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

Gage. Vertical staff.

Channel. Somewhat shifting after high water. 

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. Conditions are favorable for accurate results but because of missing gage

heights the estimates can not be considered better than fair. 

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

Service.

UNCOMPAHGRE RIVER BASIN.

TraCOMPAHORE RIVER AT OTJRAY, COLO.

Location. Near highway bridge in sec. 31, T. 44 N., B. 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 31,1911. 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. 

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 to approximately 6 second-feet and is returned to the river

below the station. 

Accuracy. Records for stages below 55 second-feet are good, but those above that

point are somewhat uncertain. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

TJNCOMPAHGRE RIVER NEAR FORT CRAWFORD, COLO.

Location. On the north line of sec. 23, T. 48 N., R. 9 W., New Mexico principal 

meridian, 2 miles north of Fort Crawford, Colo. Nearest important tributary, 

Happy Canyon Creek, enters about 8 miles downstream.

Records available. July 11, 1910, to October 31, 1911. From October 2, 1907, to 

October 31, 1910, a station waa maintained half a mile west of Fort Crawford, but 

the records at the two stations are not directly comparable as diversions amounting 

to 200 second-feet and more during the irrigation season are made between the 

two points.

Drainage area. 197 square miles.

Gage. Vertical staff.

Channel. Somewhat shifting; frequent measurements necessary.

Discharge measurements. Made from the bridge.

Winter flow. During the winter months observations are discontinued because of 

ice.

Diversions. Beside the diversions mentioned previously many other diversions are 

made above and below the station. Uncompahgre River is so overappropriated 

that the United States Reclamation Service is constructing a tunnel and canal to 

divert 1,300 second-feet from Gunnison River into Uncompahgre River above this 

point.

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

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

TTNCOMPAHGRE RIVER AT MONTROSE, OOLO.

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

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

Records available. April 22,1903, to October 31,1911.

Drainage area. 565 square miles.

Gage. Vertical staff; location and datum unchanged.

Channel. Extremely shifting.

Discharge measurements. Made from the bridge.

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 overappropriated 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. Sufficient discharge measurements were made during 1911 to enable 

computation of discharges by indirect method for shifting channels; the estimates 

may be considered fair.

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

TTNCOMPAHGRE RIVER NEAR DELTA, COLO.

Location. At highway bridge on range line between R. 95 and R. 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 October 31, 1911.

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 now. 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 of discharge must be rated as fair or, possibly, for certain 

periods, good, as sufficient measurements have not been made to give data for 

using the indirect method for shifting channels to the fullest extent.

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

Discharge measurements of Uncompahgre River near Delta, Colo., in 1911.

FREMONT RIVER BASIN. 

FBEMONT BIVEB NEAR THURBEB, UTAH.

Location. At the ranch of John Smith, in see. 6, T. 29 S., R. 4 E., Salt Lake meridian.,

2 mileB below the town of Thurbe?.

Records available. May 13,1909, to December 31, 1911. 

Drainage area. 720 square miles. 

Gag«k Vertical staff. 

CfcanneL Shifts during high water. 

Discharge measuxement»»7--3$«l» 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 control. 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 are only approximate at times, because of the shifting character

of the stream bed and probable effect of backwater at gage. 

Cooperation. Maintained in cooperation with the State of Utah.

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

August 7, 1911: Gage height, 5.13 feet, discharge, 60.8 second-feet.

Daily gage height, in feet, of Fremont River near Thurber, Utah, for 1911.

MUDDY CREEK NEAR EMERY, UTAH.

Location. At Jacobsen's ranch, about 1 mile above the boundary line of the Manti 

Forest Reserve, in the NE. J NE. J sec. 21, T. 21 S., E. 6 E., Salt Lake base and 

meridian.

Records available. May 1 to July 31,1909; July 23,1910, to December 31,1911.

Drainage area. 87 square miles.

Gage. Inclined staff.

Channel. Shifting.

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

and medium stages.

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

the months of December, January, and February.

Diversions. The station is above the headgates of the Emery, Independence Co., 

and Lower canals, and is near a proposed reservoir site; records indicate the 

natural flow of the stream and the amount of water available for storage.

Accuracy. Poor because of shifting character of the stream bed.

Cooperation. Maintained in cooperation with the State of Utah.

IVIE CREEK NEAE EMERY, UTAH.

Location. In sec. 5 or 6, T. 24 S., R. 5 E., Salt Lake base and meridian, about 1^

miles from Oak Spring ranch, 15 miles southwest of Emery and 3 miles below the

confluence of Red Creek and Clear Creek. 

Records available. May 3 to December 31, 1911. 

Drainage area. Not accurately known. 

Gage. Vertical staff on left bank. 

Channel. Shifting.

Discharge measurements. Made by wading about 50 feet below the gage. 

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

February; at times the creek is frozen to the bottom. 

Diversions. Oak Spring ranch ditch, 1^ miles above the gage, diverts practically

all the flow of Ivie Creek except during two or three weeks of high water in the

spring and occasional periods of short floods.

Accuracy. Measurements and gage heights insufficient for estimates of discharge. 

Cooperation. Maintained in cooperation with the State of Utah.

ESCALANTE RIVER BASIN. 

ESCALANTE CREEK NEAR ESCALANTE, UTAH.

Location. About 2 miles below the town of Escalante, Utah, in sec. 9, T. 35 S., R. 3 

E. Salt Lake meridian; just below the mouth of Winslow or Pine Creek.

Records available. August 5, 1909, to December 31, 1911.

Drainage area. 315 square miles.

Gage. Vertical staff.

Channel. Shifts during the sudden short flooods to which the stream is subject.

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

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

winter months.

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

records at this point show the amount of unappropriated and waste waters.

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

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

daily and monthly discharge during certain periods is apt to be in error to a greater 

amount than this.

Cooperation. Maintained in cooperation with the State of Utah.

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

August 10, 1911: Gage height, 2.42 feet; discharge, 10.85 second-feet.

Daily gage height, in feet, of Escalante Creek near Escalante, Utah, for 1911.

SAN JUAN BIVEB BASIN. 

SAN JUAN RIVER 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 to December 31, 1911.

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

Gage. Vertical staff. The gage was originally Iqcated 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 and a new gage installed November 23 

100 yards below the new highway bridge. The relation between the different 

gages is not known.

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.

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, 1J feet on bottom, and 1J feet deep. There are court decrees for diversions of 20 second-feet above the station and 175 second-feet from 

tributaries entering above.

Accuracy. As the station has not yet been completely rated, estimates of discharge 

can not be presented.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

SAN JUAN RIVER NEAR BLOOMFIELD, N. NEX.

Location. At suspension bridge, 1J miles below Bloomfield, N. Mex., in T. 29 N., 

K. 11 W., New Mexico principal merdian. Nearest tributary, Canyon Largo, 

enters 10 miles above.

Records available. September 28, 1909, to October 3, 1911. From December 9, 

1908, to October 31,1910, a station was maintained at Blanco, 11 miles upstream. 

The records at Bloomfield and Blanco are very nearly comparable, as the only 

intervening tributary is Canyon Largo, and this carries water only during a small 

portion of the year.

Drainage area. 5,190 square miles (measured from Land Office map).

Gage. Automatic recording gage installed February 11, 1910, which was washed out 

July 22,1911, replaced August 12, 1911, about 150 feet below its former location, 

and again washed out October 4, 1911. The original gage was of the wire type, 

attached to the bridge and referred to the same datum.

Channel. Very shifting.

Discharge measurements. Made from suspension bridge.

Diversions. Considerable water diverted for irrigation above the station.

Winter flow. Ice causes some backwater during the winter months.
202 SURFACE WATER SUPPLY, 1911, PART IX.

Floods. On October 6, 1911, the river reached a stage of 12 feet, which was the 

highest leached sice the station was established. It is estimated that the flow 

was about 80,000 second-feet at the maximum stage. A flood stage was reached 

September 8,1909, but it was not of such magnitude as that of October 6,1911.

Accuracy. On account of the shifting of the channel the estimates have been prepared by the indirect method, and can not be considered better than fair.

Cooperation. Station maintained in cooperation with the Territorial engineer.

Discharge measurements of San Juan River near Bloomfield, N. Mex., in 1911.

SAN JUAN RIVER AT SHIPROCK, N. MEX.

Location. At highway bridge one-fourth mile south of Shiprock Indian agency, 

about sec. 13, T. 12 N., R. 2 W. Navajo principal meridian. The nearest tributary, Chaco River, which enters a short distance above, is an intermittent stream 

carrying water only during certain portions of the year. /

Records available. January 14 to October 6, 1911, when the station was discontinued.
204 SURFACE WATER SUPPLY, 1911, PART IX.

Drainage area. 13,070 square miles (from Land Office map).

Gage. Chain gage.

Channel. The measurements made do not indicate any change, but it is probable

that changes occur during high water.

Discharge Measurements. Made from bridge and by wading. 

Winter now. Practically no ice.

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

Floods. During the first week of October, 1911, the most severe flood of many years

occurred. The crest of this flood was approximately 22 feet on the gage. 

Accuracy. Prior to the flood of October conditions were favorable for reliable results. 

Cooperation. Station was maintained in cooperation with the Territorial engineer

and the United States Indian Service.

ANIMAS RIVER AT DURANGO, COLO.

Location. At the footbridge at the foot of Fourteenth Street in Durango. Nearest

tributary, Lightner Creek, enters just above. 

Records available. From June 20, 1901, to December 31, 1905, at a point above

Lightner Creek; January 1, 1910, to September 2, 1911. 

Drainage area. 694 square miles (Hayden's atlas). 

Gage. Automatic recording gage. 

Channel. Liable to shift during high water. 

Discharge measurements. Made from bridge.

Winter flow. Little if any backwater from ice during the winter months. 

Diversions. Water is diverted above the station for irrigation. 

Floods. The severest flood in many years occurred in the first week of October, 1911,

when the river reached a maximum stage of 13.6 feet. 

Accuracy. Estimates for 1911 based on measurements during 1911 are fair, but no

estimates have been made for 1910 as no measurements were made during that

year. 

Cooperation. Records furnished through the courtesy of the San Juan Water &

Power Co.

QOOOOOOO

ANIMAS RIVER AT AZTEC, N. MEX.

Location. At the highway bridge in sec. 9, T. 30 N., R. 11 W., one-half mile west 

of Aztec. No important tributaries between the station and the mouth of the 

river, about 12 miles below.

Records available.-"-June 21 to December 14, 1904; June 8, 1907, to December 31, 

1911.

Drainage area. 1,300 square miles (measured from Land Office map).

Gage. Vertical staff. The gage was originally placed at a wooden bridge one-half 

mile below the present site, but was transferred to its present position September 

13, 1908. There is no determined relation between the two gage datums.

Channel. Shifting during high water, but fairly permanent at other times.

Discharge measurements. Made from bridge and by wading.
SAN" JTJAN RIVEE BASIN.

Winter flow. Ice forms to a considerable depth along the edges during the greater 

part of the winter months, but the river seldom freezes across. Slush ice is of 

frequent occurrence.

Diversions. Between Durango and Aztec many ditches divert water for irrigation.

flood discharge. Two severe floods have occuired on the Animas since records 

have been maintained. That of September 6, 1909, reached a maximum stage of 

11 feet with a corresponding discharge of 16,000 second-feet; that of October 6, 

1911, a stage of 13.5 feet with an approximate discharge of 30,000 second-feet. 

The latter flood is the severest that has occurred in many years.

Accuracy. Prior to the October flood, conditions \were favorable for reliable results. 

A change in the channel was caused by the flood, and for the remainder of the year 

the estimates can not be considered better than fair.

Cooperation. During 1911 station was maintain ad in cooperation with the Territorial engineer and W. G. Black, Aztec, N. Mex.

SAN JUAN BIVEE BASIN. 221

LA PLATA RIVER NEAR LA PLATA, N. MEX.

Location. At highway bridge in sec. 3, T. 31 N., R. 13 W. New Mexico principal

meridian, 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 July 21, 1911. 

Drainage area. Approximately 340 square miles. 

Gage. Chain gage; location and datum unchanged. 

Channel. Extremely shifting.

Discharge measurements. Made from the bridge and 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 ditches take water below. 

Accuracy. Measurements insufficient for estimates of discharge. 

Cooperation. During 1911 this station was maintained in cooperation with the

Territorial engineer.

GILA RIVER BASIN. 

GILA RIVER NEAR REDROCK, N. MEX.

Location. Four miles northeast of Bedrock post office, near the eastern edge of T. 

18 N., B. 18 W., New Mexico principal meridian, in the Middle Box Canyon. 

Nearest important tributary is Mancos Draw, an intermittent stream which enters 

12 miles above the station. A number of large washes come into the river above 

and below the station, and during flood stages carry large quantities of water.

Records available. May 14, 1908, to December 31, 1911.

Drainage area. 3,500 square miles (measured from Land Office map).

Gage. Automatic recording gage. The original staff gage was located at the mouth 

of the canyon. On July 16, 1909, readings on this gage were discontinued and a 

Friez automatic gage, reading to a new datum was installed at the present site. 

The Friez gage was washed out by the flood of July 23, 1911, and a Barrett and 

Lawrence automatic gage, reading to the same datum, was established in its place 

October 3, 1911, but was not put into operation until December 1, 1911. All 

gage heights July 23, to November 30,1911, were read on a staff gage attached to 

the automatic float box and refer to the datum of the automatic gages.

Channel. Extremely shifting.
GILA EIVEE BASIN. 229

Discharge measurements. Made from car and cable 400 feet below the gage, and

at low stage by wading. 

Winter flow. Except for a fringe of ice along the edges of the river, ice does not

interfere with the accuracy of the results. 

Diversions. A number of large irrigation ditches and reservoirs divert water above

the station. 

Flood flow. On July 23, 1911, a very severe flood occurred in the valley. Owing

partly to a log jam the maximum stage at the station was about 22 feet with a

discharge of about 18,000 second-feet. 

Accuracy. Owing to the extremely shifting character of the channel and to lack of

sufficient discharge measurements, reliable estimates of discharge for 1911, can

not be made. 

Cooperation. Station maintained in cooperation with the Territorial engineer and

Thomas Lyons, Gila, N. Mex.

Location. Below Arizona & Eastern Railroad bridge on San Carlos Indian Reservation, about 1 mile east of San Carlos, and one-half mile above mouth of Saa Carlos 

River.

Records available. 1899 to 1905 at a point about 1 mile below present site; August 

17, 1910, to February 5, 1911, when station was discontinued.

Drainage area. Not measured.

Gage. Vertical staff fastened to west pier of railroad bridge. On September 7,1910, 

a staff gage was installed at old trestle bent, 600 feet below bridge, at an independent datum. The relation between these gages has been established and all 

gage heights are referred to the datum of the new gage.

Channel. Shifting sand.

Discharge measurements. Made from railroad bridge and by wading.

Accuracy. Estimates of discharge not prepared, as results have not been satisfactory.

Daily gage height, in feet, ofGila River at San Carlos, Ariz.,for 1911.

GILA RIVER AT KELVIN, ARIZ.

Location. About half a mile below mouth of Mineral Creek, 1 mile below Kelvin, 

Ariz., 1 and 25 miles above Florence, Ariz.

Records available. January 26 to December 31, 1911.

Drainage area. Not measured.

Gage. Inclined staff bolted to basalt ledge on right bank opposite observer's home. 

This gage was destroyed by the March flood and was replaced by painting the 

section directly on the rock about 10 feet downstream from original gage. On 

November 23 an inclined staff for low water was bolted to the rock to which the 

first gage was attached. The original datum has been maintained.

Channel. Shifting sand.

Discharge measurements. Made from the public car and cable about threefourths of a mile above gage, and by wading.

Diversions. About 7,000 acres of land irrigated from this stream above the station.

Accuracy. Although channel shifts, the control is fairly permanent between floods. 

Results are considered good for a station of this type. Estimates have been 

prepared from curves covering periods between floods.

SAN FRANCISCO RIVER AT ALMA, N.

Location. About half a mile southwest of Alma, in sec. 4, T. 11 N., R. 20 W.

Nearest tributary, Mineral Creek, enters a short distance above. 

Records available. October 18, 1904, to December 31,. 1907; January 1, 3909, to

August 12, 1911, when the station was discontinued. 

Drainage area. 1,670 square miles (from Land Office map).

Gage. Vertical staff; site and datum differ somewhat from those of the original gage. 

Channel. Extremely shifting.

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

Winter flow. The flow of this river is practically unaffected by ice. 

Diversions. A few small ditches divert water above the station. 

Accuracy. Owing to the shifting character of the channel and lack of sufficient

measurements, estimates of discharge can not be made. 

Cooperation. From its reestablishment in 1909 the station was maintained in

cooperation with the Territorial engineer.

SAN FRANCISCO RIVER AT DAM ABOVE CLIFTON, AEIZ.

Location. At the diversion dam of the Arizona Copper Co., and 6$ miles above junction with Gila Kiver. Station was moved upstream January 16, 1911.

Records available. October 24, 1910, to December 31, 1911.

Drainage area. Not measured.

Gage. Painted on inclined crest of dam and on vertical face of right abutment. 

From October 24, 1910, to January 16, 1911, observations were made on vertical 

staff fastened to retaining wall on left bank just above the highway bridge at 

Clifton. On the latter date it was removed to the diversion dam 1J miles farther 

upstream. The original gage at the dam was a vertical staff in two sections bolted 

to the upstream face of dam and right abutment. The vertical staff was damaged 

by high water, and the paiated gage was installed at the same datum November 

13, 1911.
GILA EIVEE BASItf. 235

Discharge measurements. Made from highway bridge at Clifton and by wading.

Diversions. A email amount of water is used for irrigation one-fourth mile above 

Arizona Copper Co.'s dam. At the dam, about 14 second-feet is diverted to 

develop power and is returned to the river above the bridge at Clifton.

Accuracy. The station was moved to the diversion dam because the channel at the 

bridge is somewhat shifting. On account of frequent repairs to the dam and difficulty of obtaining gage readings the results have not been satisfactory, and estimates of daily or monthly discharge have not been prepared.

WHITEWATER CREEK NEAR MOGOLLON, N. MEX.

Location. At the power house of the Socorro Mines Co., 3 miles south of Mogollon, 

500 feet below the confluence of north and south forks, in sec. 4, T. 11 S., B. 19 

W., below all tributaries.

Records available. October 1, 1909, to December 31, 1911.

Drainage area. 34 square miles (measured from topographic sheet).

Gage. Vertical staff gage on right bank, half a mile below the old weir gage, installed May 30, 1911.

Channel. Fairly permanent except during high water.

Discharge measurements. Made by wading at nearly all stages.

Winter flow. Little if any backwater from ice during the winter months.

Diversions. All water used in the power plant is returned above the gage.

Accuracy. Owing to the shifting character of the channel during high water and to 

lack of discharge measurements, no estimates of discharge have been made from 

the staff gage readings. The estimates made prior to September 30, 1911, are by 

weir.

Cooperation. From October 1, 1909, to September 30, 1911, records of daily diecharge over a weir installed at this point by the Socorro Mines Co. were kept and 

furnished through their courtesy.

The following discharge measurement was made by G. H. Russell. 

May 30,1911: Gage height, 1.08 feet (old weir gage read 0.65); discharge, 10.4 eecondfeet.

Daily gage height, in feet, of Whitewater Creek near Mogollon, N. Mex.,for 1911.

SANTA CRUZ RIVER NEAR NOGALES, ARIZ.

Location. Just below proposed dam site on Yerba Buena ranch, about 7 miles northeast of Nogales, half a mile above the city pumping plant.

Records available. March 22, 1907, to December 31, 1911; fragmentary. .

Drainage area. Not measured.

Gage. Inclined staff fastened to large cottonwood tree on right bank a short distance 

below intake of small irrigation ditch.

Channel. Shifting sand.

Discharge measurements. Made from car and cable about 100 feet above gage, 

and by wading.

Diversions. About 140 acres of land irrigated from this stream above the station. A 

small ditch takes water just above the station for irrigation a short distance below. 

At low stages a temporary ditch is built on the right bank; when this ditch is in 

operation the gage shows only the height of the water in the ditch.

Accuracy. Because of the effect of the temporary ditch and the extremely shifting 

character of the stream bed, no estimates of discharge can be prepared from the 

data obtained.

Cooperation. Gage height record furnished by officials of Santa Cruz County and 

the Nogales Board of Trade.

244 SURFACE WATEB SUPPLY, 1911, PAET IX.

AGUA FRIA BIVEB NEAR GLENDALE, ABIZ.

Location. At old diversion dam of the Beardgley irrigation project at Camp Dyer, 

in sec. 28, T. 6 N., K. 1 E., Gila and Salt Eiver base and meridian, 4 miles below 

mouth of Castle Creek and 22 miles northwest of Glendale.

Records available. November 10, 1910, to December 31, 1911.

Drainage area. Not measured.

Gage. Painted on the upstream face of the dam at the right of the opening for each 

channel. At low and medium stages the stream flows through the larger opening, 

which is near the right bank. The openings in the dam were made during the 

flood of 1895, when a portion of the masonry near each end was washed out.

Channel. Shifting sand.

Discharge measurements. Made by wading.

Accuracy. Measurements insufficient for estimates of daily and monthly discharge 

for 1911. Full reliance can not be placed on the gage-height record after January 

26,1011.

Cooperation. Gage-height record is furnished by the Beardsley Irrigation Co., A. L. 

Harris, engineer, through the watchman at the dam.

FLOOD OP OCTOBER, 1911, IN THE REGION OF THE SAN 

JUAN, SAN MIGUEL, AND LA PLATA MOUNTAINS.

By G. H. RUSSELL and G. A. GRAY.

From September 25 to October 6, 1911, rain was general over a 

large portion of the Rocky Mountain region and was heavy, increasing 

with the elevation, on the slopes of the San Juan, San Miguel, and 

La Plata Mountains, from which flow the headwaters of San Juan, 

Dolores, Chama, Rio Grande, and Gunnison Rivers. Until October 

5, however, the fall had at no time been excessive, and the rivers and

i White River flows southward into Mexico and discharges into the Gulf of California.
FLOOD OF OCTOBER, 1911. 247

their tributaries were easily carrying the run-off within their banks, 

But on that day a very heavy downpour occurred on the higher slopes 

of the ranges, above altitude 7,000 feet.

At Gladstone, Colo., elevation 10,500 feet, the United States 

Weather Bureau recorded 8.05 inches for the day. Below this elevation the precipitation diminished, although as far down as Pagosa 

Springs it amounted to 3.67 inches and at Uncompahgre 3.70 inches.

All the precipitation was in the form of rain, which carried with it 

to the streams any snow that had previously fallen on the upper 

slopes. The exceptionally heavy run-off -caused by such a combination of phenomena, poured into streams already full to their banks, 

resulted in extraordinarily high stages on all rivers heading in the 

region.

Chama River overflowed its banks, inundated all bottom lands, 

and caused considerable damage to ranches and bridges along its 

course. At Chama, N. Mex., the Denver & Rio Grande Railroad 

bridge and several hundred feet of track were taken out.

Conejos River also left its banks and did considerable damage. 

The channel at Jacob's ranch shifted entirely away from the gage 

and bridge to which the gage was attached. The maximum discharge 

at this point was probably close to 6,000 second-feet.

The Rio Grande at Wason and Del Norte, Colo., reached a height 

never before recorded. At Del Norte the State engineer's gage registered a maximum of 5.9 feet, the estimated maximum discharge 

being 12,000 second-feet. At Wason the State's automatic gage registered 7.05, the maximum discharge being close to 8,000 second-feet.

Some damage was done to ranches and also irrigation in the 

vicinity of Del Norte and Monte Vista, Colo. The roadbed of the 

Creede branch of the Denver & Rio Grande Railroad was so damaged 

that traffic was delayed for several days.

Dolores River at Dolores reached a height of 10.2 feet on the State 

engineer's gage, or about 8 feet above low-water stage. The estimated discharge at this stage is about 10,000 second-feet. The Rio 

Grande Southern Railroad suffered the greatest loss in this valley, 

much of its track being entirely destroyed and all more or less damaged 

for a stretch of 35 miles. Agriculturists along the course also sustained severe losses.

On San Miguel and Uncompahgre rivers conditions were similar to 

those on the other streams, but the damage was probably not so great.

The San Juan and its upper tributaries reached stages that exceeded 

any in memory or tradition. The Animas at Durango registered 13.6 

feet on the State engineer's gage, or 11.5 feet above low water. At 

Aztec, N. Mex., flood marks showed the river to have reached a 

height of 13.5 feet, or 10.5 feet above normal. The maximum dis-
