SURFACE WATER SUPPLY OF THE LOWER MISSISSIPPI 

RIVER BASIN, 1911.

By W. B. FKEEMAN and H. J. DEAN.

AUTHORIZATION OF WORK.

This volume is Part VII of a series of 12 reports presenting results 

of measurements of flow made on certain streams in the United 

States during the calendar year 1911. The reports are listed in the

a 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.

6 SURFACE WATEE SUPPLY, 1911, PAET VH.

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

In the execution of the work many private and State organizations 

have cooperated. Acknowledgement for such cooperation is made 

on page 13 and also in connection with the description of each station 

affected by the cooperative work.

PUBLICATIONS.

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 as Water-Supply 

Paper 280. An index to the reports containing stream-flow measurements prior to 1904 has been published as Water-Supply 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 run-off in second-feet 

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

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

used in this series of reports are second-feet, second-feet per square
LOWER MISSISSIPPI EIVEE BASIN.

mile, run-off in 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 accompanying table of equivalents.

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

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

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

regards time and area.

"Run-off, 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 I foot. The term is 

commonly used in connection with storage for irrigation.

CONVENIENT EQUIVALENTS.

The following is a list of convenient equivalents for use in hydraulic 

computations:

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 discharge, table of monthly and yearly discharge and run-off. For stations located at weirs or dams the gage^height table is omitted.
LOWER MISSISSIPPI KIVEE BASIN". 11

In addition to statements regarding the location and installation of 

eurrent-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 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 readings 

of negative values 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 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 discharge 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
12 SURFACE WATER SUPPLY, 1911, PAKT VII.

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 8-9, 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 measurements of stream flow 

made by the Geological Survey and records of rainfall collected by 

the Weather Bureau.

Plate III shows typical gaging stations.

Plate IV shows current meters l used in the work.

ACCURACY AND RELIABILITY OF FIELD DATA AND 

COMPARATIVE RESULTS.

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

conditions of 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; 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.

LOWER MISSISSIPPI EIVEE BASIN. 13

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 to afford any 

engineer the means of examining and adjusting to his own needs the 

results of the computations. The table of monthly discharge is 

so arranged as to give only a general idea of the flow at the station and should not be used for other than preliminary estimates. 

The determinations of daily discharge allow more detailed studies 

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

determined.

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

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

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

COOPERATION AND ACKNOWLEDGMENTS.

The work in Colorado was carried on in cooperation as follows:

The United States Forest Service furnished the services of a hydrographer for measuring the streams in the national forests, and also 

furnished the gage heights.

Mr. C. W. Comstock, State engineer, furnished the field data on a 

number of stations on Arkansas River and cooperated in the maintenance of other stations. He also furnished complete records at 

several stations.

The Central Land & Irrigation Co. paid the field expenses incurred 

at the stations in the Big Sandy basin.

The 'work in New Mexico was carried on in cooperation with Mr. 

C. D. Miller, Territorial engineer, who paid the field expenses incurred 

at most of the stations. Cooperation with the Atchison, Topeka & 

Santa Fe Railway Co. and with individuals was arranged by the 

Territorial engineer.

The work in Mississippi was carried on hi cooperation with the 

Tallahatchie Drainage Commission.

ARKANSAS RIVER AT CANON CITY, COLO.

*

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

of the canyon, and l| miles above Canon City. The nearest important tributary 

is Grape Creek, which enters above.

Records available. May 1,1888, to December 31, 1911.

Drainage area. 3,060 square miles.

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

1909. The original Geological Survey gage was established April 17, 1889. On 

October 4, 1895, a new staff gage was established on the left bank opposite 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.

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

is necessary to move the gage in order to obtain 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 secondfeet from intervening tributaries.

Cooperation. During 1911 this station was maintained and records were furnished 

by the State engineer of Colorado.

NOTE. Accuracy notes are not given as the entire record was furnished by the State engineer of Colorado.

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, 1911. 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.

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 

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

causes a difference in reading?. 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, a staff gage referred to a different datum waa 

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. Accuracy notes not given, as the entire record was furnished by the State engineer of Colorado. 

ARKANSAS RIVER NEAR NEPESTA, COLO.

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

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

the nearest important tributary.

Records available. September 8,1897, to October 31,1903; July 14,1909, to December 15, 1911.

Drainage area. 9,130 square miles.

Gage. An automatic recording gage with its 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 is the control point, and as the results show shifting 

conditions it is evident the dam is 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 is subtracted from the flow at the bridge in order to show the amount of water below 

the canal.

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 records 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.

NOTE. Accuracy notes not given, as the entire record was furnished by the State engineer of Colorado. 

ARKANSAS RIVER AT HOLLY, COLO.

Location. At highway bridge half a mile southeast of Holly, on line between sees.

14 and 15, T. 23 S., R. 42 W., 1 mile below the mouth of Wild Horse Creek, an

intermittent stream.

Records available. October 15, 1907, to December 31, 1911. 

Drainage area. Approximately 25,000 square miles. 

Gage. A number of gages have been used at the station, but the readings have all

been referred to the same datum, except readings subsequent to October 25, 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 1,047 second-feet from Arkansas

River between the stations at New Fort Lyons and Holly, and diversions of 753

second-feet from intervening tributaries. There are many diversions from

Arkansas River below Holly, in Kansas. 

Accuracy* Owing to the shifting character of the channels, the estimates can not be

considered better than fair. 

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

Colorado.

Discharge measurements of Arkansas River at Holly, Colo., in 1911.

WEST BEAVER CREEK NEAR VICTOR, COLO.

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.

Records available. Monthly estimates from January 1, 1905, to December 31,1911.

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 3$ 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.

Accuracy. Company states that records are probably correct within 5 per cent.

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

Light & Power Co.

LOWER MISSISSIPPI RIVEB BASIN. 41

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

at ordinary stages.

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

Diversions. There are court decrees for diversions of 112 second-feet from Purgatory 

River above Trinidad and 348 second-feet below. There are decrees for diversions of 110 second-feet from tributaries entering above the station.

Accuracy. Although the channel is somewhat shifting, sufficient measurements 

have been made to form a basis for estimates of flow, which may be considered 

good.

Cooperation. Station maintained in cooperation with the State engineer of Colorado.

CANADIAN RIVER AT LOGAN, N. MEX.

Location. Three-fourths of a mile above 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, 1911.

Drainage area. Approximately 12,000 square miles. 

Gage. Automatic recording gage was installed August 5, 1910, at a point three

quarters of a mile above bridge and referred to a datum different from that of gage

previously used. The original gage was a staff. On the reeetablishment 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. 

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 from the Canadian itself. 

Accuracy. As the station as referred to the datum established in 1910 has not been

completely rated, no estimates of discharge have been made. 

Cooperation. The station was maintained in cooperation with the Territorial

engineer of New Mexico.

Artificial control. A short distance above the station is a reservoir designed to

hold the flood water for use in irrigation farther down the valley. 

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

have been made. 

Cooperation. Station was maintained in cooperation with the Territorial engineer

of New Mexico and Mr. A. J. Meloche, of Raton, N. Mex., who furnished the

gage heights.

RAYADO RIVER NEAR ABREU'S RANCH, NEAR CIMARRON, N. MEX.

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

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

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

Drainage area. Not measured.

Gage. Automatic recording gage, installed May 5,1911. A staff gage, located threequarters of a mile above Abreu's ranch house, was read 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.

Cooperation. Prior to October, 1909, stations in the Rayado River basin were 

maintained by the New Mexico Hydrographic Survey, but since that time they 

have been maintained by the United States Geological Survey in cooperation 

with the Territorial engineer of New Mexico.

MOEA EIVEE AND LA CUEVA CANAL AT LA CUEVA, N. MEX.

Location. At highway bridge at La Cueva, a few miles above the mouth of the 

Cebolla and a short distance downstream from the intake of the La Cueva canal, 

and just below wasteway, about sec. 24, T. 20 N., R. 16 E.

Records available. August 25, 1903, to July 31, 1911, when the station was 

discontinued.

Drainage area. Not measured.

Gage. The original gage was washed out by a flood on September 29, 1904. A new 

staff gage, referred to a datum 1.32 feet above that of the original gage, was installed 

April 29, 1905, and has remained unchanged since that date. The canal gage 

is at a footbridge below the wasteway; its datum has remained constant.

Channel. Somewhat shifting, both in the river and the canal.

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

Winter flow. Ice causes slight backwater for a few days during the winter months.

Diversions. Above the station only a little water is diverted so that the combined 

flow of the river and canal represent closely the natural run-off from the drainage area.

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

the estimates of flow can not be considered better than fair.

Cooperation. Station maintained in cooperation with the Territorial engineer of 

New Mexico.

SAPELLO RIVER AT LOS ALAMOS, N. MEX.

Location. At Los Alamos post office near sec. 28, T. 18 N., R. 16 E. No important

tributary enters between this station and the mouth, a few miles east. 

Records available. August 22, 1903, to May 31, 1911, when the station was

discontinued.

Drainage area. 144 square milea. 

Gage. A chain gage installed in April, 1905, to replace the original gage which was

destroyed by flood September 29, 1904. 

Channel. Somewhat shifting. 

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

wading at ordinary stages.
58 SURFACE WATER SUPPLY, 1911, PART VH.

Winter flow. There is very little backwater from ice during the winter period.

Diversions. A considerable part of the normal flow is diverted for irrigation above 

the station.

Accuracy. Owing to the shifting channel and insufficient measurements, the estimates of flow can not be considered better than fair.

Cooperation. Station maintained in cooperation with the Territorial engineer of 

New Mexico.

The following discharge measurement was made by R. L. Cooper: May 10,1911, 

gage height, 0.04 foot; discharge, 1.3 second-feet.

Daily gage height, in feet, and discharge, in second-feet, of Sapello River at Los Alamos,

N. Mex., for 1911.

PAJABITO GREEK NEAR HANLEY, N. HEX.

Location. In sec. 26, T. 11 N., R. 28 E., 2 miles north of Hanley, a quarter of a mile 

above mouth*of Vigil Creek, the nearest tributary.

Records available. August 30, 1911, to December 31,1911.

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. Station maintained in cooperation with the Territorial engineer of 

New Mexico. The gage heights are furnished through the courtesy of Mr. V. W. 

Moore, Tucumcari, N. Mex.

The total discharge of floods in June is estimated as 300 acre-feet and in July 1,600 acre-feet. The discharge 

of flood on Aug. 23 is estimated as 2,000 acre-feet and on Aug. 28 as 2,400 acre-feet.

UTE CREEK NEAR LOGAN, N. MEX.

Location. Four miles above the mouth of Ute Creek in the northeastern corner of 

T. 13 N., R. 32 E. No important tributaries enter within several miles of the 

station.

Records available. August 12, 1904, to June 30, 1906; April 13, 1909, to December 31, 1911.

Drainage area. Not measured.

Gage. Automatic recording gage installed August 1, 1911, to replace original staff 

gage used since 1904. Datum of recording gage different from that of staff gage.

Channel. Very shifting.

i Maximum gage height 4.55 feet.
60 SUKFACE WATEK SUPPLY, 1911, PART VII.

Discharge measurements. Made by wading at ordinary stages. Estimates of 

flood discharge are made by elope measurements and the use of Kutter's formula.

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

Diversions. A small amount of water is diverted above the station for irrigation.

Accuracy. Owing to the shifting nature of the stream bed, the records can be considered only fair. The finding of an error in obtaining the cross section of the 

stream necessitated the revision of the back data which are published in this 

report.

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

Territorial engineer of New Mexico.

NOTE. The finding of an error in obtaining the cross section of the stream necessitated the revision of all 

high-water discharges for previous years. The corrected daily discharges are published above. These 

were determined from rating curves covering short periods of time and by the indirect method for shifting 

channels.

LOWEB MISSISSIPPI RIVER 79

BED RIVER BASIN. 

BED BIVEB AT ABTHUB CITY,

Location. At a bridge at Arthur City, Tex.

Records available. January 1, 1905, to December 31, 1911. The United States 

Weather Bureau has maintained a gaging station at this point since 1891.

Drainage area. Not measured.

Gage. Vertical staff, fastened to one of the piers of the bridge.

Channel. Composed of sand; shifting.

Discharge measurements. Made from the bridge.

Winter flow. Ice does not affect the flow.

Accuracy. The accuracy is uncertain. Discharge measurements made in 1905-6 

indicate a shifting channel. One measurement madej in 1911 checks the mean 

curve drawn through the previous measurement. No (aeasurement made during 

1907-1910. The rating table, used to work up the recjords, is the one published 

in Water Supply Paper 209, page 51, extended down ty> a gage height of 4.7 feet. 

Daily discharges are not published because of their unreliability, but the monthly 

values are considered fair.

Cooperation. Gage-height record furnished by the United States Weather Bureau.

The following discharge measurement was made at this station by T. U. Taylor: 

December 28,1911, gage height, 11.0 feet; discharge, 9,500 decond-feet.

Daily gage height, in feet, of Red River at Arthur City, \Tex.,for 1907-1911.
