SURFACE WATER SUPPLY OF THE LOWER MISSISSIPPI 

RIYER BASIN, 1912.

By ROBERT FOLLANSBEE.

AUTHORIZATION AND SCOPE OF WORK.

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

measurements of flow made on streams in the United States during 

the calendar year 1912.

The data presented in these reports were collected by the United 

States Geological Survey under authority implied in the organic law 

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

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

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

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

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

1895, successive sundry civil bills passed by Congress have carried 

the following item and appropriations:

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

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

Annual appropriations for the fiscal year ending June 30 

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

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

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

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

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

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

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

1911 to 1914, inclusive................................... 150,000

In the execution of the work many private and State organizations 

have cooperated, either by furnishing data or by assisting financially 

in collecting the data. Acknowledgments for cooperation of the first 

kind are made in connection with the description of each station 

affected and of the second kind on page 14.

Measurements of stream flow have been made at about 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 1912 gaging stations were maintained by the Survey
6 SURFACE WATER SUPPLY, 1912, PART VII.

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

discharge measurements were made at other points. In connection 

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

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

many sections of the country and will be made available in the regular water-supply papers from time to time.

PUBLICATIONS.

A report for each calendar year has been prepared embodying the 

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

containing stream-flow measurements prior to 1904 has been published as Water-Supply Paper 119. Circulars are also available giving complete lists of the gaging stations maintained by the Survey to 

date and a list of the reports relating to the water supply of the 

country.

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

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

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

in 12 parts, as shown in 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 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,
10 SURFACE WATER SUPPLY, 1&12, PART vn.

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

regards time and area.

"Run-off (depth in inches)" is the depth to which the drainage 

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

period were conserved and uniformly distributed on the surface 

It is used for comparing run-off with rainfall, which is usually 

expressed in depth in inches.

An "acre-foot" is equivalent to 43,560 cubic feet and is the 

quantity required to cover an acre to the depth of 1 foot. The term 

is commonly used in connection with storage for irrigation work.

CONVENIENT EQUIVALENTS.

EXPLANATION OF DATA.

For each regular current-meter gaging station the following data 

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

table of daily gage heights, table of daily discharges, table of monthly 

and yearly discharges and run-off. For stations located at weirs or 

dams the gage-height table is omitted.

In addition to statements regarding the location and installation 

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

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

gage height to discharge, covering such points as ice, logging, shifting
12 SURFACE WATEB SUPPLY, 1912, PAET VII.

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 to the gage 

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

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

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

The discharge measurements and gage heights are the base data 

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

The rating table gives, either directly or by interpolation, the discharge in second-feet corresponding to every stage of the river recorded during the period for which it is applicable. It is not published in this report, but can be determined from the tables of daily 

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

ordinates and discharge in second-feet as abscissas.

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

corresponding to the observed gage heights as determined from the 

rating tables.

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

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

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

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

water surface was at crest height, and the corresponding discharge 

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

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

during the month. On this the computations for the remaining columns, which are defined on pages 9-10, are based.

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

description of station, have been collected by the methods commonly 

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

ACCURACY AND RELIABILITY OF FIELD DATA AND 

COMPARATIVE] RESULTS.

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

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

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

degree of permanency of channel and of permanency of the relation 

between discharge and stage.

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

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

due to misinterpretation of stage and flow data.

In order to give engineers and others information regarding the 

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

daily discharge tables, stating the probable accuracy of the rating 

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

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

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

The accuracy column in the monthly discharge table does not 

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

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

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

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

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

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

Even though the monthly means for any station may represent 

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

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

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

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

as a rule not feasible to make adequate correction.

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

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

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

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

The determinations of daily discharge allow more detailed studies of
14 SURFACE WATER SUPPLY, 1912, PART VII.

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.

The work in New Mexico was carried on in cooperation with J. A. 

French, State engineer, and was supervised from a suboffice established at Santa Fe. Other cooperative work in the lower Mississippi 

River basin is duly acknowledged in connection with the descriptions 

of the stations affected.

DIVISION OF WORK.

The field data for the Arkansas River drainage basin in Colorado 

were collected under the direction of Robert Follansbee, district 

engineer, assisted by G. A. Gray, Raymond Richards, R. H. Fletcher, 

H. B. Waha, and J. L. Mathias.

The work in New Mexico was under the general supervision of 

Robert Follansbee. After August 1, the work was in direct charge 

of G. A. Gray, assistant engineer, who was assisted by R. L. Cooper, 

J. E. Powers, and C. J. Emerson.

The ratings, special estimates, and computations for stations in 

Colorado were made and the completed data prepared for publication 

under the direction of Robert Follansbee by Raymond Richards, 

assisted by R. H. Fletcher.

The ratings, special estimates, and computations for stations in 

New Mexico were made by G. A. Gray and H. J. Dean.

The ratings and computations in the Yazoo River basin were made 

by Warren E. Hall and J. G. Mathers.

The report was edited by Mrs. B. D. Wood.

STATION RECORDS.

ARKANSAS RIVER BASIN. 

EAST FORK OF ARKANSAS RIVER NEAR LEADVILLE, OOLO.

Location. At highway bridge in sec. 16, T. 9 S., R. 80 W., about 300 yards above 

mouth of Tennessee Fork, 3 miles northwest of Leadville.

Records available. April to August 31, 1890; June 18 to September 29, 1903; June 

5, 1911, to November 14, 1912.

Drainage area. 52 square miles (measured on topographic sheet).

Gage. Vertical staff.

Channel. Somewhat shifting.
ABKANSAS EIVEE BASIN. 15

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

Winter flow. Ice causes backwater during the winter months.

Diversions. There is a court decree for a diversion of 2 second-feet from the East 

Fork above the station, but none below.

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

stage is subject to considerable diurnal fluctuation at certain seasons, due to the 

alternate melting and freezing. Mean daily gage heights based on one reading 

per day are therefore liable to considerable error. Estimates have only been 

made for the days on which the gage was read, and can only be considered fair.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

ARKANSAS RIVER AT GRANITE, COLO.

Location. At Granite, in sec. 31, T. 11 S., R. 79 W., below the mouth of Lake Creek 

and above Lost Canyon and Clear creeks.

Records available. May 1,1897, to September 10, 1899; April 6, 1910, to November 

30, 1912.

Drainage area. 425 square miles.

Gage. Automatic recording gage established in 1910; datum of recording gage bears 

no determined relation to that of the vertical staff gage which was used from 1897 

to 1899 and which was located at the highway bridge near the railroad station.

Channel. Practically permanent.

Discharge measurements. Made from car and cable.

Winter flow. Ice causes backwater during the winter months and the records are 

discontinued.

Artificial control. The discharge is affected by the operation of the Twin Lakes 

reservoir and by a flume used to carry water from Lake Creek to a point below the 

station.

Diversions. There are court decrees for diversions of 76 second-feet from the Arkansas between this station and the junction of Tennessee and East forks, and 

diversions of 22 second-feet from the intervening tributaries.

Cooperation. Since 1910 this station has been maintained and records have been 

furnished by the State engineer of Colorado.

NOTE. Values in the above table have been changed slightly from the State engineer's records to conform with the standard computation rules of the Geological Survey.

ARKANSAS RIVER AT CANON CITY, COLO.

Location. Just below the suspension bridge at Hot Springs Hotel, at the mouth of 

the canyon, and 1J miles above Canon City. Nearest important tributary is 

Grape Creek, which enters above.

Records available. May 1,1888, to November 30, 1912.

Drainage area. 3,060 square miles.

Gage. Automatic recording gage established by the State engineer in September, 

1909. The river shifted away from thia gage early in 1912, and a chain gage reading to the same datum was placed on the opposite side of the river and used during 

the year. The original Geological Survey gage was established April 17, 1889. 

On October 4,1895, a new staff gage was established on the left bank about 100 

feet below the original gage and referred to the same datum. At low stages it 

read 0.4 foot lower than the original gage, but at high stages the readings were the 

same. On August 26, 1902, a gage was established on the right bank near the 

first gage and referred to the same datum. The datum of the recording gage now 

used is 2.00 feet higher than that of the last gage.
ARKANSAS EIVER BASIN. 21

Channel. The channel shifts to such an extent during high water that at times it is 

necessary to move the gage in order to read the gage heights.

Discharge measurements. Made from car and cable.

Winter flow. Ice causes backwater during the winter months.

Diversions. There are court decrees for diversions of 131 second-feet from the Arkansas between the stations at Canon City and Salida, and diversions of 2,286 

second-feet from intervening tributaries.

Cooperation. During 1912 this station was maintained and records were furnished 

by the State engineer of Colorado.

NOTE. Values in the above table have been changed slightly from the State engineer's records to conform with the standard computation rules of the Geological Survey.

ARKANSAS RIVER AT PUEBLO, COLO.

Location. At Main Street Bridge in Pueblo, 2 miles above the mouth of Fountain

Creek, the nearest tributary. 

Records available. September 19, 1894, to December 31,1912. From May 1,1885,

to September 30, 1886, a station was maintained at Pueblo by the State engineer;

from June 1, 1887, to September 30, 1887, a station was maintained at a point 9

miles above Pueblo; from May 1,1889, to August 31, 1889, the Geological Survey

maintained the station 9 miles above Pueblo. 

Drainage area. 4,600 square miles.
ARKANSAS EIVER BASIN. 23

Gage. An automatic gage located 150 feet below Main Street Bridge has been used 

since March'22, 1911. It is referred'to the same datum as the chain gage on the 

Main Street Bridge, which was installed July 7, 1905, but the slope of the river 

between the two points causes differences in readings. A vertical staff placed 

at the Santa Fe Avenue Bridge on September 19, 1894, was used until July 10, 

1898, when a second gage was placed at Main Street Bridge, and used until March 3, 

1900. From that date until July 14, 1902, a vertical staff near the Union Avenue 

Bridge was used. From that date until July 7, 1905, when the present gage was 

placed in position, a staff gage referred to a different datum was used.

Channel. The channel shifts to such an extent during high water that it has been 

necessary to move the gage in order to read the gage heights.

Discharge measurements. Made from Main Street Bridge.

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

Diversions. There are court decrees for diversions of 637 second-feet from Arkansas 

River, between the station at Canon City and Pueblo, and diversions of 372 

second-feet from intervening tributaries.

Cooperation. From 1894 to 1908 this station was maintained by the United States 

Geological Survey. At present the station is maintained and records are furnished 

by the State engineer of Colorado.

NOTE. Values in the above table have been changed slightly from the State engineer's records to conform 

with the standard computation rules of the Geological Survey.

ARKANSAS RIVER NEAR NEPESTA, COLO.

Location. At the dam of the Oxford Farmers' Canal Co., in sec. 31, T. 21 S., E. 60 W. 

1J miles above Nepesta; about 6 miles below the mouth of Huerfano River, the 

nearest important tributary.

Becords available. September 8, 1897, to October 31, 1903; July 14, 1909, to November 30, 1912.

Drainage area. 9,130 square miles.

Gage. An automatic recording gage with ita zero coinciding with the lowest point 

of the diversion dam has been in use since 1910. There is no known relation 

between the present gage and that used in 1903.

Channel. The diversion dam ia the control point, and as the results show shifting 

conditions it is evident that the dam ia not permanent.

Discharge measurements. Made from the bridge at Nepesta except during low 

water, when measurements are made by wading. Between the gage and the 

measuring section is a wasteway from the canal. The flow at this point ia subtracted from the flow at the bridge in order to show the amount of water flowing 

over the dam.

Winter flow. Ice causes backwater during a portion of the winter months.

Diversions. There are court decrees for diversions of 1,552 second-feet from the 

Arkansas between Pueblo and Nepesta, and approximately 1,600 second-feet 

from intervening tributaries. The discharge recorda given in this report do not 

include the flow of the canal.

Cooperation. Since 1909 this station has been maintained and records have been 

furnished by the State engineer of Colorado.

ARKANSAS RIVER AT LA JUNTA, COLO.

Location. Half a mile below the east bridge at La Junta; no important tributary

within several miles. 

Records available. April 11, 1912, to December 7, 1912. From December 5, 1893,

to December 31, 1895, a station was maintained near the city pumping plant.

During 1899 and 1901 a station was maintained at the head of the Fort Lyon Canal

by the Great Plains Water Co. From April 7, 1903, to October 31, 1903, a station 

' was maintained 1 mile east of La Junta and a number of discharge measurements

were made during 1904. From August 27, 1908, to November 30, 1908, a station

was maintained half a mile northwest of La Junta, just below the mouth of

been referred to the same datum except those from October 25 to December 31, 

1911, when a different datum was used.

Channel. Very shifting.

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

at low stages.

Winter flow. Ice causes backwater during a portion of the winter months.

Diversions. There are court decrees for diversions of 1,072 second-feet from Arkansas 

River between the stations at La Junta and Holly, and diversions of 1,253 secondfeet from intervening tributaries. There are many diversions from Arkansas 

River below Holly, in Kansas.

TENNESSEE FORK NEAR LEADVILLE, COLO.

Location. At highway bridge in see. 16, T. 9 S., K. 80 W., a few hundred yards 

above the mouth of the stream and about 3 miles northwest of Leadville.

Records available. February 8, 1911, to November 20, 1912.

Drainage area. 45 square milea (measured on topographic sheet).

Gage. Vertical staff. 

Channel. Data too meager to determine.

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

at ordinary stages.

Winter now. Ice causes backwater during the winter months.

Diversions. There are court decrees for diversions of 24 second-feet above the 

station. There is also a decree for diversion of 18.5 second-feet from the headwaters of Eagle Eiver to Tennessee Fork above the station.

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

discharge have been made.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

HALF MOON CREEK NEAR LEADVILLE, COLO.

Location. In sec. 6, T. 10 S., E. 80 W., 1 mile above mouth of stream and 6 miles 

southwest of Leadville; no tributaries below the station.

Records available. April 10, 1911, to November 16, 1912.

Drainage area. 30 square miles (measured on topographic sheet).

Gage. Vertical staff.

Channel. Shifting.

Discharge measurements. Made by wading.

Winter flow. Ice causes backwater during the winter months and records are 

discontinued.

Diversions. There are court decrees for diversions of 12 second-feet above the 

station.

Accuracy. Owing to the high altitude of the drainage basin, the stage is likely to show 

considerable diurnal fluctuations at certain seasons of the year, due to alternate 

melting and freezing, and the mean daily gage height based on one reading for 

day may be considerably in error. For this reason the estimates can not be considered better than fair.

Cooperation. This station is maintained in cooperation with the United States 

Forest Service.

COTTON WOOD CREEK BELOW HOT SPRINGS, NEAR BUENA VISTA, COLO.

Location. In the Leadville National Forest, at bridge in sec. 22, T. 14 S., R. 79 W»,

half a mile below Hot Springs Hotel and 6 miles west of Buena Vista; 2 miles

below mouth of South Fork, the nearest tributary. 

Records available. April 9, 1911, to December 31, 1912. From September 25,

1910, to September 13,1911, a station was maintained in section 21,1 mile above 

' the present station.

 Drainage area. 72 square miles (measured on forest atlas). 

Gage. Vertical staff. 

Channel. Probably permanent, although the rough section makes the results

erratic.
ABKANSAS RIVEB BASIN.

Discharge measurements. Made from bridge or by wading.

Winter flow. The river is open during the winter months on account of hot springs 

above.

Diversions. There are court decrees for diversions of 133 second-feet from Cottonwood Creek, of which 28 second-feet are above the station.

Accuracy. Owing to the very rough condition of the stream bed, the estimates 

can not be considered other than fair or possibly good.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

NORTH COTTONWOOD CREEK NEAR BUENA VISTA, COLO.

Location. At highway bridge in sec. 10, T. 14 S., R. 79 W., 6 miles northwest of 

Buena Vista, just below a small stream enjbering from the west, and 1J miles below 

mouth of Silver Creek.

Records available. October 5, 1911, to November 30, 1912.

Drainage area. 50 square miles (measured on forest atlas).
ARKANSAS RIVER BASIN. 37

Gage. Vertical staff.

Channel. Permanent.

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

wading at ordinary stages.

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

Diversions. There are court decrees for diversions of 32 second-feet from North 

Cottonwood Creek.

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

river stage is subject to considerable diurnal fluctuations at certain seasons, due to 

the alternate melting and freezing. Therefore the mean daily gage height as 

determined from one reading per day may be considerably in error. This uncertainty in mean gage height and the many interpolated discharges make the estimates only fair.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

CHALK CREEK NEAR ST. ELMO, COLO.

Location. In the Leadville National Forest at highway bridge in Bee. 28, T. 15 S.,

R. 79 W., just below the cascades of Chalk Creek and 6 miles east of St. Elmo.

Nearest tributary is a small intermittent stream entering from the north just below. 

Records available. March 10, 1911, to December 31, 1912. From September 6 to

December 28, 1910, a station was maintained in sec. 24, T. 15 S., R. 79 W. 

Drainage area. 75 square miles (measured OD forest atlas). 

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 only slight backwater. 

Diversions. There are no court decrees for diversions from Chalk Creek above the

station, but below there are decrees for 132 second-feet. 

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

is considerable diurnal fluctuation of stage" at certain seasons, due to the alternate

melting and freezing, and that the mean daily gage height as based on one reading

per day may be considerably in error. The uncertain gage height and the many

interpolated discharges can make the estimates only fair. 

Cooperation. Station maintained in cooperation with the United States Forest

Service.

Discharge measurements of Chalk Creek near St. Elmo, Colo., in 191%.

SOUTH FORK OF AEKANSAS RIVER AT PONCHA, COLO.

Location. At highway bridge about half a mile from Poncha, in sec. 10, T. 49 N., 

R. 8 E. Nearest tributary, Poncha Creek, enters one-fourth mile below.

Records available. January 14, 1911, to December 31, 1912.

Drainage area. 140 square miles (measured from Forest atlas).

Gage. Vertical staff.

Channel. Permanent prior to the highwater of 1912, when it shifted.

Discharge measurements. Made from bridge during highwater and by wading at 

ordinary stages.

Winter flow. Springs keep this stream open during the winter months.

Diversions. There are court decrees for diversions of 113 second-feet from the South 

Fork above the station, and 66 second-feet below. There are also decrees for 

diversions of 76 second-feet from the North Fork which enters above.

Accuracy. The high altitude of the drainage basin causes diurnal fluctuations of 

stage during certain seasons, due to alternate melting and freezing. The mean 

daily gage height is based on three readings per day, the maximum stage, which 

occurs during the night, and readings at 6 a. m. and 6 p. m. The mean stage as 

determined in this manner may be somewhat in error, and therefore the estimates 

can not be considered better than good.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

44 SURFACE WATER SUPPLY, 1912, PART VH.

PONCHA CREEK AT PONCHA, COLO.

Location. At highway bridge in sec. 10, T. 49 N., R. 8 E., near Poncha, about onefourth mile above the mouth of creek.

Records available. January 14, 1911, to December 31, 1912.

Drainage area. 89 square miles (measured on Forest Atlas).

Gage. Vertical staff.

Channel. Shifting.

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

at ordinary stages.

Winter flow. Springs prevent the creek from freezing to any considerable extent.

Diversions. There are court decrees for diversions of 7 second-feet above the station, 

but none below.

Accuracy. Owing to the high altitude of this drainage basin, the stage is subject to 

considerable diurnal fluctuations at certain seasons of the year due to alternate 

melting and freezing, and the mean daily gage height based on morning and 

evening readings and the maximum stage for 24 hours may be somewhat in error. 

The uncertain mean gage height and the shifting conditions make the estimates of 

daily discharge only fair.

Cooperation. Station maintained in cooperation with the United States Forest 

Service.

WEST BEAVER CREEK NEAR VICTOR, CO1O.

Location. At the Skagway power station of the Arkansas Valley Railway, Light & 

Power Co., in sec. 30, T. 16 S., R. 68 W., about 7 miles southeast of Victor.

Becords available. January 1, 1905, to December 31, 1912.

Drainage area. 70 square miles.

Method of compiling records. The water used through the power house, which is 

brought by pipe line from the reservoir 3J miles upstream, is measured hourly by 

weir. To this amount is added or subtracted a quantity representing the gain or 

loss in the reservoir during the period. The seepage through the reservoir is 

measured by weir and added to the above to obtain the final result. The record 

therefore represents the flow of the stream (less evaporation from the stored water) 

as if there were no reservoir.

Diversions. Above the power reservoir the town of Victor has three reservoirs from 

which water is diverted for municipal purposes. Colorado Springs receives its 

water supply from four reservoirs in the upper basin. There are filings (which 

have not yet been adjudicated) for diversions from the basin of 52 second-feet by 

ditch and 5 second-feet by pipe line. This water is diverted into Lake Moraine 

and thence by natural channels to Colorado Springs. The town of Altman, for 

municipal supply, has filed on five reservoir sites in the upper basin, having a 

combined capacity of 2,300 acre-feet. Below the power plant there are adjudicated decrees for diversions of 57 second-feet from Beaver Creek, which is formed 

by East and West Beaver creeks. In addition, there is an irrigation reservoir in 

operation which has a filing for 4,760 acre-feet.
ARKANSAS RIVER BASIN. 47

, Cooperation. Records are furnished through courtesy of Arkansas Valley Railway 

Light & Power Co., which states that records are probably correct within 5 per 

cent.

NOTE. Values represent the actual flow of the stream if no water was consumed and were determined 

by adding the amount drawn from the reservoir plus the reservoir loss or gain plus the flow over the 

spillway to the amount used in the turbines.

HUERFANO RIVER AT BADITO, COLO.

Location. At the concrete bridge at Badito in sec. 4, T. 27 S., R. 68 W. The nearest tributary, Yellowstone Creek, enters a short distance above.

Becords available. August 28, 1912, to December 20, 1912.

Drainage area. Not measured.

Gage. Chain gage located at the bridge.

Channel. Shifting.

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

prdinary and low stages.

Winter flow. No data.

Diversions. Water is diverted from the Huerfano "above and below the station, but 

the exact amount is indeterminable, owing to conflicting court decrees.

Cooperation. Station maintained and records furnished by the State engineer of 

Colorado.

CANADIAN RIVER AT LOGAN, N. MEX.

Location. Three-fourths of a mile above the railroad bridge in sec. 15, T. 13 N., R. 

33 E., 1 mile south of Logan, 5 miles below mouth of Ute Creek, and about 5 miles 

above mouth of Arroyo Largo or Tucumcari Creek.

Records available. June 29, 1904, to February 26, 1905; December 22, 1908, to 

December 31,1912.

Drainage area. Approximately 12,000 square miles.

Gage. Automatic recording gage was installed August 5, 1910, at a point threequarters mile above bridge and referred to a datum different from that of gage 

previously used. The original gage was a staff. On the reestablishmerit of the 

station in 1908, a gage was painted on one of the bridge piers, but referred to a 

new datum. This gage was used.until August 5,1910, when the present gage was 

placed in position.
56 SURFACE WATEB SUPPLY, 1912, PART VIE.

Channel. Very shifting.

Discharge measurements. Flood measurements are made by floats, owing to the

great amount of drift carried in the stream. Measurements at ordinary stage are

made from a car and cable, and at low water by wading.

Winter flow. Ice causes slight backwater during a portion of the winter months. 

Diversions. Some water is diverted from the headwater streams, as irrigation is

carried on quite actively, but there are no diversions in the vicinity of this

station. 

Accuracy. The estimates of discharge made in 1912 can be rated as fair.

RAYADO EIVEE ABOVE ABEETTS EANCH, NEAE CIMAEEON, N. MEX.

Location. Six miles above Abreu's ranch house, at the mouth of the box canyon, 

15 miles southwest of Cimarron, near sec. 29, T. 25 N., R. 18 E.

Records available. May 4, 1911, to December 31, 1912.

Drainage area. 56 square miles; from private surveys made for George H. Webster, 

of Cimarron, N. Mex.
ARKANSAS RIVER BASIN. 63

Gage. Automatic recording gage, installed May 5,1911. A staff gage, located threefourths of a mile above Abreu's ranch house, was read from January 1,1909, until 

May 5, 1911, when the station was moved to its present site. No determined 

relation between the two gages. No streams enter between the two points, but it is 

possible that some of the flow is lost by sinking into the sand.

Channel. Slightly shifting.

Discharge measurements. Made by wading.

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

Diversions. No water is diverted above the station and the records represent the 

natural run-off.

Accuracy. Estimates of discharge can be considered good.

PAJARITO CREEK NEAR HANLEY, N. MEX.

Location. In sec. 26, T. 11 N., R. 28 E., 2 miles north of Hanley; one-fourth mile 

above mouth of Vigil Creek, the nearest tributary.

Records available. August 30, 1911, to May 20, 1912, when the station was discontinued.

Drainage area. 310 square miles.

Gage. Automatic recording gage.

Channel. Data too meager to determine.

Discharge measurements. Made by floats during high water and by wading at 

ordinary stages.

Winter flow. No data.

Diversions. No water is diverted above the station, and therefore the records represent the natural run-off.

Accuracy. Owing to the possibility of shift and the fact that the upper portion of 

the rating curve is determined by floats and slope measurements, no estimates of 

discharge have been made.

Cooperation. Gage heights are furnished through the courtesy of Mr. V. W. Moore, 

Tucumcari, N. Mex.

80 SURFACE WATER SUPPLY, 1912, PART VII.

BED BIVEB BASIN. 

MEDICINE BLUFF CREEK NEAR LAWTON, OKLA.

Location. At Medicine Park, in sec. 18, T. 3 N., R. 12 "W., 12 miles northwest of 

Lawton. The nearest tributary is Little Medicine Bluff Creek, which enters a 

few hundred yards above.

Records available. November 26 to December 31, 1912.

Drainage area. Approximately 110 square miles.

Gage. Vertical staff.

Channel. Should be practically permanent, as river bed is composed largely of 

rock, which is covered with some silt and gravel. The channel forms a pool a 

half mile or more in length, with a ledge-rock control point.

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

wading at low stages.

Controlled flow. The flow is controlled to a great extent by the reservoir of the 

Lawton waterworks, located a mile upstream, which has an area of 1,100 acres. 

The entire low-water flow is used by the waterworks.

Accuracy. Since the establishment of the station there has been practically no flow.

Cooperation. Station maintained in cooperation with the United States Reclamation Service.

The following estimate of flow was made on November 26, 1912: 

Gage height, 0.76 foot; discharge, 0.3 second-foot.

Daily gage height, in feet, of Medicine Bluff Creek near Lawton, Olda.,for 1912.
