SUKFACE WATER SUPPLY OF WESTERN GULF OF 

MEXICO BASINS, 1915.

AUTHORIZATION AND SCOPE OP WORK.

This volume is one of a series of 14 reports presenting results of 

measurements of flow made on streams in the United States during 

the year ending September 30, 1915.

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 years ending June 30, 1895-1916.

In the execution of the work many private and State organizations 

have cooperated, either by furnishing data or by assisting in collecting data. Acknowledgments for cooperation of the first kind are 

made in connection with the description of each station affected; 

cooperation of the second kind is acknowledged on pages 11 and 12.

Measurements of stream flow have been made at about 3,800 points 

in the United States and also at many points in Alaska and the 

Hawaiian Islands. In July, 1915, 1,350 gaging stations were being 

maintained by the Survey and the cooperating organizations. Many 

miscellaneous discharge measurements were made at other points.

6 SURFACE WATER SUPPLY, 1915, PART VIII.

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. 

Information in regard to publications relating to water resources is 

presented in the appendix to this report.

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 that represent a rate of flow, as secondfeet, gallons per minute, miner's inches, and discharge in secondfeet per square mile, and (2) those that represent the actual quantity 

of water, as run-off in depth in inches, acre-feet, and millions of 

cubic feet. The principal terms used in this series of reports are 

second-feet, second-feet-per square mile, run-off in inches, acre-feet, 

and millions of cubic feet. They may be defined as follows:

"Second-feet" is an abbreviation for "cubic feet per second." 

A second-foot is the rate of discharge of water flowing in a channel 

of rectangular cross-section 1 foot wide and 1 foot deep at an average 

velocity 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 tables of convenient equivalents (p. 7).

"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 an area would 

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

uniformly distributed on the surface. ' It is used for comparing runoff with rainfall, which is usually expressed in depth of inches.

An "acre-foot," equivalent to 43,560 cubic feet, 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.

"Millions of cubic feet" is applied to quantities of water stored in 

reservoirs, most frequently in connection with studies of flood 

control.

The following terms not in common use are here defined:

"Stage-discharge relation," an abbreviation for the expression 

"relation of gage height to discharge.

"Control," a term used to designate the section or sections of 

the stream below the gage which determine the stage-discharge relation at the gage. It should be noted that the control may not be the 

same section or sections at all stages.
CONVENIENT EQUIVALENTS.

The "point of zero flow" for a gaging station is that point on the 

gage the gage height to which the surface of the river would 

fall if there were no flow.

CONVENIENT EQUIVALENTS.

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

computations:

EXPLANATION OF DATA.

The data presented in this report cover the year beginning October 

1, 1914, and ending September 30, 1915. At the 1st of January 

in most parts of the United States much of the precipitation in the 

preceding three months is stored as ground water, in the form of 

snow or ice, or in ponds, lakes, and swamps, and this stored water 

passes off in the streams during the spring break-up; at the end of 

September, on the other hand, the only stored water available for 

run-off is possibly a small quantity in the ground; therefore the runoff for the year* beginning October 1 is practically all derived from 

precipitation within that year.

The base data collected at gaging stations consist of records of 

stage, measurements of discharge, and general information used 

to supplement the gage heights and discharge measurements in 

determining the daily flow. The records of stage are obtained either 

from direct readings on a staff gage or from a water-stage recorder 

that gives a continuous record of the fluctuations. Measurements 

of discharge are made with a current meter by the general methods 

outlined in standard textbooks on the measurement of river discharge. (See Pis. I and II.)

From the discharge measurements rating tables are prepared tha{ 

give the discharge for any stage, and these rating tables, when applied 

to the gage heights, give the daily discharge from which the monthly 

and yearly mean discharge is determined.

- The data presented for each gaging station in the area covered by 

this report comprise a description of the station, a table giving results 

of discharge measurements, a table showing the daily discharge of 

the stream, and a table of monthly and yearly discharge and run-off.
10 SUEFACE WATEB SUPPLY, 1915, PART VIII.

If the base data are insufficient to determine the daily discharge, 

tables giving daily gage heights and results of discharge measurements 

are published.

The description of the station gives, in addition to statements 

regarding location and equipment, information in regard to any conditions that may affect the constancy of the stage-discharge relation, 

covering such subjects as the occurrence of ice, the use of the stream 

for log driving, shifting of channel, and the cause and effect-of backwater; it gives also information as to diversions that decrease the 

flow at the gage, artificial regulation, maximum and minimum 

recorded stages, and the accuracy of the records.

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

corresponding to the mean of the gage heights read each day. At 

stations on streams subject to sudden or rapid diurnal fluctuation the 

discharge obtained from the rating table and the mean daily gage 

height may not be the true mean discharge for the day. When such 

stations are equipped with water-stage recorders, the true mean daily 

discharge may be obtained by computing the mean daily gage height 

and applying it to the rating table, by averaging quantities of discharge for regular intervals during the day, or by means of a discharge integrator, an instrument operating on the principle of the 

planimeter and containing as an essential element the rating curve 

of the station.

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

gives the mean flow 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 that 

given in the maximum column. Likewise, in the column headed " Mini- 

. mum," 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 average flow computations recorded in the remaining columns, which are 

defined on pages 7-9, are based.

ACCURACY OP FIELD DATA AND COMPUTED RESULTS.

The accuracy of stream-flow data depends primarily (1) on the 

permanence of the discharge relation and (2) on the accuracy of 

observations of stage, measurements of flow, and interpretation of 

records.

Footnotes added to the daily-discharge tables give information 

regarding the probable accuracy of the rating tables used, and an 

accuracy column is inserted in the monthly-discharge table. For tl}e 

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," 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 letter in the column headed "Accuracy," in the monthly-discharge table, rates the accuracy of the monthly mean and not that 

of the estimate of maximum or minimum discharge or the discharge 

for any one day. The rating is determined by considering the accuracy of the rating curve, the probable reliability of the observer, the 

number of gage readings per day, the range of the fluctuation in stage, 

and local conditions. In this column A indicates that the determination of 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.

The monthly means for any station may represent with high accuracy the quantity of water flowing past the gage, but the figures 

showing discharge per square mile and depth of run-off in inches may 

be subject to gross errors caused by the inclusion of large noncontributing districts in the measured drainage area, by lack of information concerning water diverted for irrigation or other use, or by 

inability to interpret the effect of artificial regulation of the flow of 

the river above the station. "Second-feet per square mile" and 

"run-off (depth in inches)" are therefore not computed if such errors 

appear probable. The computations are also omitted for stations on 

streams draining areas in which the annual rainfall is less than 20 

inches. All figures representing "second-feet per square mile" and 

"run-off (depth in inches)" previously published by the Survey 

should be used with caution because of possible inherent sources of 

error not known to the Survey.

The table of monthly discharge gives only a general idea of the 

flow at the station and should not be used for other than preliminary 

estimates; the tables of daily discharge allow more detailed studies 

of the variation in flow. It should be borne~in mind, however, that 

the observations in each succeeding year may be expected to throw 

new light on data previously published.

COOPERATION.

The work, in Texas was carried on in cooperation with the State 

Board of Water Engineers of Texas, consisting of J. C. Nagle, chairman; John Wilson, and E. B. Gore. Stations in Nueces and Guadalupe River basins were established and maintained prior to September 

1, 1915, by the Board of Water Engineers.

The work in New Mexico to January 1, 1915, was carried on in 

cooperation with the State through James A. French, State engineer.

The United States Reclamation Service paid the salaries of gage 

readers at three stations in the Rio Colorado, Rio Hondo, and Rio 

Taos drainage basins and furnished a large part of the money expended in the lower Pecos River valley to June 30, 1915. After that
12 SURFACE WATER SUPPLY, 1915, PART VIII.

date the Service continued cooperation in the lower Pecos River 

Valley by furnishing the equipment.

The United States Forest Service aided by furnishing gage readers 

at stations on Rio Colorado, Rio Vallecitos, and South Fork of Gallinas 

River.

The United States Indian Office furnished water-stage recorders and 

paid the salaries of gage readers at stations on Rio Pueblo and Rio 

Lucero.

The stations on the Rio Grande from El Paso to Eagle Pass, Tex., 

were maintained and the records furnished by the Commission for the 

Equitable Distribution of the Waters of the Rio Grande.

Equipment and financial assistance in maintaining stations in 

Chama River basin were given by the Arlington Land Co., through 

its chief engineer, H. I. Reid.

DIVISION OF WORK.

Previous to September 1, 1915, the data for stations in eastern 

Texas were collected under the direction of Warren E. Hall, district 

engineer; after September 1, 1915, data were collected under the 

direction of Glenn A. Gray, district engineer, who was assisted by 

R. C. Pierce, junior engineer, and R. J. Hank and R. C. Thaxton, 

State hydrographers.

For stations on Colorado River at Austin, Guadalupe River at 

New Braunfels, and San Antonio River at San Antonio, Tex., the data 

were prepared for publication by Warren E. Hall, assisted by B. J. 

Peterson. Data for the remaining stations in Texas were prepared 

for publication under the direction of Glenn A. Gray, district engineer, 

assisted by William Kessler, junior engineer.

Prior to June 30, 1915, field data for stations in New Mexico and 

western Texas were collected under the direction of Glenn A. Gray, 

district engineer, assisted by W. R. King and C. J. Emerson, junior 

engineers, and J. E. Powers, E. L. Redding, R. S. Watrous, and R. J. 

Hank, State hydrographers. After June 30, 1915, field data for New 

Mexico were collected under the direction of Robert Follansbee, district engineer, assisted by W. R. King, and field data for western 

Texas under the direction of Glenn A. Gray, district engineer.

Ratings and computations were made by Glenn A. Gray, assisted 

by W. R. King, C. J. Emerson, R. J. Hank, and William Kessler.

The manuscript was prepared by Lasley Lee and reviewed by G. C.

Stevens.

TRINITY RIVER BASIN. 

TRINITY RIVER AT BRIDGEPORT. TEX.

LOCATION. At the suspension bridge on Balsora-Bridgeport road, half a mile southwest of the center of Bridgeport, Wise County, a quarter of a mile above the 

Chicago, Rock Island & Gulf Railway Co.'s pumping plant, and 1 mile below 

mouth of Gentry Creek. I
TRINITY RIVER BASIN. 13

DRAINAGE ABEA. 1,060 square miles (revised).

RECORDS AVAILABLE. October 1, 1914, to September 30, 1915. Record of stage has

been obtained by the United States Weather Bureau since August 16, 1908. 

GAGE. Weight and tape gage of the Mott type fastened to downstream side of bridge,

56 feet from north end of guard rail; read by U. E. Byers.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge or by wading. 

CHANNEL AND CONTROL. Bed of stream composed of clay, gravel, and sand. Banks

are high, slightly wooded, and are overflowed at a stage of 25 feet. One channel

at ordinary stages; several after the water has overflowed the banks. Control is

a rock outcrop three-quarters of a mile below bridge. 

EXTREMES OF STAGE. Maximum stage recorded during year, 28.9 feet June 8;

minimum stage, 0.80 foot February 13 to 19.

1908-1915: Maximum stage, 28.9 feet June 8,1915, minimum stage, 1.80 feet

on several dates.

WINTER PLOW. Stage-discharge relation not seriously affected by ice. 

DIVERSIONS. None above the station for power development; extensive irrigation

not required as ordinarily the precipitation in the drainage basin is sufficient to

mature crops. The operation of the few small pumping plants along the stream

produces little noticeable effect. 

REGULATION. So far as is known there are no water-power plants, dams, reservoirs,

lakes, or swamps above or immediately below which influence the flow at this

point. 

COOPERATION. Gage-height record furnished by United States Weather Bureau.

Data inadequate for determination of daily discharge.

The following discharge measurement was made by M. R. Hall:

May 26, 1915: Gage height, 9.85 feet; discharge, 2,000 second-feet.

Pinto County, 1$ miles above the mouth of Palo Pinto Creek.

DRAINAGE AREA. 20,200 square miles (revised).

RECORDS AVAILABLE. October 1, 1914, to September 30, 1915. Record of stage has 

been obtained by United States Weather Bureau since August 16, 1908.

GAGE. Vertical staff reading from 0 to 4.0 feet attached to right side, near upstream 

end of pier near middle of bridge; stages above 4.0 feet read on gage painted on 

pier. Gage read daily by L. W. Boyett.

DISCHARGE MEASUREMENTS. Made from three-span highway bridge about 600 feet 

below railway bridge.

CHANNEL AND CONTROL. Bed of stream composed of sand and gravel; probably 

shifts. Channel straight above and below for several thousand feet. Right 

bank high, wooded, rocky, and not subject to overflow; left bank wooded, composed of sand, gravel, and clay, medium in height, and subject to overflow at 

extreme stages. Position of control not known.

EXTREMES OF STAGE. Maximum stage recorded during year, 20 feet at 5.30 p. m. 

June 8; minimum stage, 0.80 foot October 15 and 16.

1908-1915: Maximum stage recorded, May 24,1908, 22.0 feet; minimum stage, 

zero on several dates.

WINTER FLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. A few pumping plants installed along stream take water to irrigate small 

areas, but quantity so pumped is too small to appreciably affect flow at this station.

REGULATION. So far as is known there are no water-power plants, dams, reservoirs, 

lakes, or swamps above or immediately below which affect the flow at this point. 

The area drained by Brazos River contains few swamps and natural lakes.

COOPERATION. Gage-height record furnished by United States Weather Bureau.

Data inadequate for determination of daily discharge.

BRAZOS EIVEE BASIN. 15

BRAZOS RIVER AT WACO, TEX.

LOCATION. At the suspension bridge on Bridge Street, in the city of Waco, KcLennan 

County, just below the Southern Traction Co.'s bridge, 2£ miles below the mouth 

of Bosque River, 4J miles above the mouth of Cottonwood Creek, about 10 miles 

above Lock No. 8, now under construction.

DRAINAGE AREA. 25,500 square miles (revised).

RECORDS AVAILABLE. September 14, 1898, to December 31, 1911; October 1, 1914, 

to September 30, 1915. Records of stage have been obtained by United States 

Weather Bureau since August 9, 1900.

GAGE. Chain gage attached to downstream guard rail of bridge, about 70 feet from 

the southwest pier; read to tenths once daily by A. E. Howell. Gage used from 

September 14, 1898, to February 29, 1908, was an inclined staff gage under the 

left end of bridge. In 1902 a gage agreeing with the inclined gage was marked 

off on the north pier of a new single-span highway bridge about 300 feet above the 

suspension bridge and was used during high water. From August 9, 1900, to 

May 21, 1902, the United States Weather Bureau used a vertical gage painted on 

the pier nearest the center of the St. Louis Southwestern Railway bridge. From 

September 25,1914, to March 23, 1915, during the reconstruction of the suspension bridge, the chain gage was on the one-span highway bridge. All gages 

were installed at the same datum, but readings probably differ slightly because 

 of differences in position.

DISCHARGE MEASUREMENTS. Made from downstream side of first one-span highway 

bridge above station.

CHANNEL AND CONTROL. Bed of stream composed of sand and gravel; shifts. Banks 

are clay, medium in height, have been improved by the city, and are overflowed 

at extreme high water. Channel straight above and below for several thousand 

feet. Position of control not known.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 26.0 feet at 6.40 

p. m., April 26 (discharge, 104,000 second-feet; determined from extension of 

rating curve and possibly subject to large error); minimum stage, 5.8 feet August 

11 and 12 (discharge, 250 second-feet).

1898-1915: Maximum stage recorded, 39.7 feet December 3, 1913 (discharge 

not determined); minimum stage, 2.00 feet March 8-10, 1902 (discharge, 20 

second-feet).

WINTER BLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. So far as is known there are no diversions of any magnitude above the 

station.

REGULATION. Lock No. 8 will eventually control the flow at this point; flow only 

slightly controlled at present. Small areas of land are irrigated above station, 

but the quantity of water diverted is only a small percentage of the total flow.

ACCURACY. Results poor; stage-discharge relation not permanent. Slight errors 

may be introduced by using one daily gage reading as the mean for the day.

COOPERATION. Gage-height record furnished by United States Weather Bureau and 

results of some discharge measurements by the State Board of Water Engineers.

COLORADO RIVER (OF TEXAS) BASIN. 

COLORADO RIVER AT AUSTIN, TEX.

LOCATION. At Congress Avenue Bridge in Austin, in Travis County, half a mile 

above Waller Creek, half a mile below Shoal Creek, a mile below Barton Creek, 

and 3i miles below the Austin dam.

AREA. 84,200 square miles (revised).
COLOEADO EIVEE (OF TEXAS) BASIN. 17

RECORDS AVAILABLE. February 15, 1898, to December 31,1911; October 1, 1914, to 

September 30,1915; September 1,1895, to April 7,1900, at Austin dam. Record 

of stage has been obtained by United States Weather Bureau since July 1, 1903.

GAGE. Dexter water-stage recorder installed on left bank at bridge, June 18, 1915. 

Before that date staff gage 150 feet above bridge was used at low water, and a chain 

gage and a gage cut and painted on bridge pier at higher stages. A new low-water 

section on the left bank at the bridge is now in use. Datum of gages unchanged.

DISCHARGE MEASUREMENTS. Made from bridge or by wading at bar below bridge.

CHANNEL AND CONTROL. Channel straight above and below the station; water under 

bridge deep; bottom very irregular and shifting. Banks clean and of medium 

height. Control is a gravel and rock shoal about 500 feet below gage; shifts at 

high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 21.0 feet September 

17 (discharge, 84,000 second-feet); minimum stage recorded, 0.5 foot December 

13-17 (discharge, 2 second-feet).

1898-1911; 1914-15: Maximum stage recorded, 33.5 feet April 7, 1900, when 

Austin dam failed (discharge, 122,000 second-feet); minimum stage recorded, 

 0.5 foot December 13-17, 1914 (discharge, 2 second-feet).

WINTER FLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. The first report of the State Board of Water Engineers shows that 

approximately 35,000 acres of land were declared irrigated in the drainage basin 

above Austin. If each acre requires 2 acre-feet per annum, 20,000 acre-feet of 

water would be diverted or pumped from the stream. In Bulletin No. 43 (p. 29), 

of the Texas Department of Agriculture it is reported that approximately 18,600 

acres of land are irrigated above the gaging station; the use of 2 acre-feet per 

annum would require 37,200 acre-feet of water. In comparing these data it must 

be borne in mind that the first acreage is declared irrigated by the users of the 

water and the last is an estimate of the number of acres actually irrigated.

REGULATION. The flow at this point is entirely regulated by the operation of Austin 

dam, about 3J miles upstream. The first report of the State Board of Water 

Engineers shows a filing by the city of Austin for municipal uses of 4,000 acre-feet 

per annum, with a storage of 30,000 acre-feet. This report also shows filings of 

144 acre-feet per annum for Winchell waterworks, 60,000 acre-feet per annum for 

power from two reservoirs in Burnet County, and an unknown amount for Marble 

Falls waterworks, all above the gaging station at Austin.

ACCURACY. Results fair.

COOPERATION. Gage heights prior to June 18, 1915, furnished by United States 

Weather Bureau. Many of the discharge measurements furnished by the State 

Board of Water Engineers.

GTJADALTTPE RIVER NEAR GONZALES. TEX.

LOCATION. Just below the Guadalupe highway bridge, 1J miles south of Gonzales,

Gonzales County, 1 mile below power house of Gonzales Water Power Co., 2£

miles below mouth of San Marcos River. 

DRAINAGE AREA. 3,620 square miles (revised). 

RECORDS AVAILABLE. July 1 to^ September 30, 1915. The United States Weather

Bureau has obtained records from a gage at power house of Gonzales Water Power

Co. since September 1, 1904.
GUADALUPE RIVER BASIN.

GAGE. Vertical staff in three sections on both banks just below the bridge; read to 

half tenths once daily by L. B. Davis; relation between this gage and that used 

by United States Weather Bureau not known.

DISCHARGE MEASUREMENTS. Made from downstream side of highway bridge.

CHANNEL AND CONTROL. Bed composed of gravel and sand; clean and not subject to 

extreme shifting. Channel below station straight for 500 feet, but above is broken 

by an island and is straight for not more than 50 feet. Banks are of medium height, 

wooded along the water's edge on the right bank and for some distance back on 

the left bank; composed of gravel and clay and not subject to overflow except 

during extremely high stages. Position of control not known.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.00 feet at 11 a. m. 

June 14 (discharge, 1,620 second-feet); minimum stage, 2.05 feet at 9.20 a. m. 

September 14 (discharge, 930 second-feet). High-water stages were reached 

August 26 and 27 and September 19-22, but gage was not read on those dates.

WINTER FLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. Some water is diverted by gravity or pumped for irrigation above this 

point, but the quantity is small in comparison with the total run-off. Irrigation 

is practiced intermittently, as rainfall is nearly sufficient for general farming, and 

it is extremely difficult to estimate the acreage irrigated and water used.

REGULATION. Flow at station regulated to a large extent by water-power plants in 

basin above. Construction at the dam of the Gonzales Water Power Co. caused 

a slight unnatural fluctuation.

ACCURACY. Results approximate. Determinations subject to considerable error, due 

to the assumption that one gage reading per day gives the mean at a fluctuating 

stage. Stage-discharge relation not permanent; gage readings subject to large 

errors, due to careless observations.

COOPERATION. Station established and records prior to September 1 collected by 

State Board of Water Engineers.

GUADALUPE RIVER NEAR CUERO, TEX.

LOCATION. At the Schleicher Bridge, 300 feet below San Antonio & Aransas Pass 

Railway bridge. 2 miles southwest of Cuero, Dewitt County, 4 miles below a 

dam used for power development

DRAINAGE AREA. 5,020 square miles (revised).

RECORDS AVAILABLE. December 26,1902, to December 31,1906; August 19 to September 30, 1915.

GAGE. Vertical staff; low-water section attached to piling under right end of railway 

bridge; high-water section bolted to left pier of highway bridge; read to tenths 

daily by M. D. Albright. Gage used December 26, 1902, to July, 1903, was a 

vertical staff gage at Carl Buchel's power house, 3 miles north of Cuero. In July, 

1903, the station was moved downstream to the San Antonio & Aransas Pass 

Railway bridge, and stage was determined by measuring with a tagged line from 

a reference point on the bridge. From 1904 to 1906 a chain gage at the railway 

bridge was used. The chain gage was referred to the reference point on the 

bridge, but the relation between it and the present gage is not known.

DISCHARGE MEASUREMENTS. Made from upstream side of highway bridge.

CHANNEL AND CONTROL. Channel straight for 300 feet above and 1,500 feet below. 

Left bank high, wooded, and not subject to overflow; right bank medium in 

height, wooded, and subject to overflow at extremely high stages. Bed composed of rock, gravel, and sand; shifts. Position of control«not known.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 29.5 feet at 7 

a. m. September 22 (discharge not determined); minimum stage, 3.5 feet at 

7 a. m. September 16 (discharge not determined).

1902-1906: Maximum stage recorded, 43.0 feet March 1, 1903 (discharge, 71,300 

second-feet); minimum stage, 5.4 feet June 20, 1906 (discharge, 370 second-feet).

WINTER FLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. The flow at this point is not greatly affected by diversions above. 

Water is diverted in small amounts only.

REGULATION. The flow is regulated by the operation of power plants upstream, 

chiefly one about 4 miles above.

COOPERATION. Station established and records prior to September 1 collected by 

the State Board of Water Engineers.

Data inadequate for determination of discharge.

The following discharge measurement was made by R. C, Thaxton:

August 19, 1915: Gage height, 5.40 feet; discharge, 928 second-feet.

SAN MARCOS RIVER AT SAN MARCOS, TEX.

LOCATION. At sewer trestle of the San Marcos Utilities Co., in San Marcos, Hays 

County, 1,000 feet below Austin-San Antonio highway bridge, half a mile above 

Rodger's Resort, 2J miles above junction with Blanco River.

DRAINAGE AREA. Indeterminate.

RECORDS AVAILABLE. July 1 to September 30, 1915.

GAGE. Vertical staff attached to sewer trestle near the right bank; read twice daily 

by A. F. Wilson.

DISCHARGE MEASUREMENTS. Made by wading.

CHANNEL AND CONTROL. Both banks of medium height and subject to overflow 

during extremely high stages. Bed composed of gravel and sand; changes 

slightly. Position of control not known, but a growth of weeds and grass in the 

channel seriously affected the stage-discharge relation.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.85 feet August 

7 and 9 (discharge, 341 second-feet); minimum stage, 2.50 feet September 30 

(discharge, 206 second-feet).

WINTER PLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. None for irrigation above station, but water is stored for use by power 

plants.

REGULATION. Flow at station regulated by the San Marcos Utilities Co. for a municipal power plant. Much of the flow comes from springs a short distance above 

station, and water is stored and released as needed.

ACCURACY. Results poor. Stage-discharge relation seriously affected in September 

by backwater due to growth of weeds in channel. Determinations subject to 

error resulting from the assumption that one gage reading gives the mean for a 

day. Regulation for power causes fluctuations in stage.

COOPERATION. Station established and records prior to September 1 collected by 

State Board of Water Engineers.

SAN MARCOS RIVER AT OTTINE, TEX.

LOCATION. Just above highway bridge a quarter of a mile southwest of Ottine, 

Gonzales County, 4 miles below mouth of Plum Creek, 10 miles above confluence of San Marcos and Guadalupe rivers.

DRAINAGE AREA. Indeterminate.

RECORDS AVAILABLE. June 22 to September 30, 1915.

GAGE. Vertical staff in four sections attached to trees on left bank about 200 feet 

above the highway bridge; read to hundredths once daily by J. H. Kaine. From 

June 22 to October 12, 1915, a vertical staff under the highway bridge was used. 

Gage heights June 22 to October 12, 1915, have been reduced to present datum 

by means of a curve of relation.

DISCHARGE MEASUREMENTS. Made by wading at shoal 200 feet above gage, or from 

downstream side of highway bridge.

CHANNEL AND CONTROL. Both banks high and wooded; not subject to overflow 

except during extremely high stages. Channel straight above and below the 

station for 150 feet. Bed composed of sand, rock, and gravel; not subject to 

extreme shifting. Position of control not known. For a few days each year during high stages in Guadalupe River backwater seriously affects the stage-discharge 

relation.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.01 feet at 6.30 

a. m. June 22 (discharge, 375 second feet); minimum stage, 2.07 feet at 7 a. m. 

August 14 and 15 (discharge, 192 second-feet).

WINTER FLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. Some water is diverted or pumped for irrigation above station, but 

quantity used is only a small percentage of the total run-off.

REGULATION. A short distance above the station is a small cotton gin that is operated 

by water power, regulating the flow to some extent. The operation of several 

small water-power plants in the upper part of the drainage basin, near San Marcos 

and Martindale, does not materially affect the distribution of the flow at this 

point.

ACCURACY. Results fair; stage-discharge relation permanent. Base data reliable. 

Determinations subject to errors due to the assumption that one gage reading 

daily gives the mean for the day although flow is artificially regulated.

COOPERATION. Station established and records prior to September 1 collected by 

State Board of Water Engineers.

SAN ANTONIO RIVER BASIN.

SAN ANTONIO RIVER AT SAN ANTONIO, TEX.

LOCATION. At Commerce Street Bridge in San Antonio, Bexar County, 3 miles below 

San Antonio Springs, the source of trie river.

DRAINAGE AREA. Indeterminate..

RECORDS AVAILABLE. January 26 to September 30, 1915.

GAGE. Vertical staff attached to concrete bridge post nearest to right bank at downstream side of bridge.

DISCHARGE MEASUREMENTS. Made from Market Street Bridge, 300 feet below gage.

CHANNEL AND CONTROL. Below a stage of 3 feet water is confined between vertical 

rock walls 38 feet apart; at stages between 3 and 4.5 feet water spreads over flat 

berms on both banks for about 30 feet; above 4.5 feet water is again confined? 

between vertical rock walls. Moss grows on the silt of which the bottom of lowwater channel is composed and by clogging meter causes some trouble in making 

discharge measurements. Control is gravel and boluder shoal about 600 feet 

below gage; shifts at high water.

EXTREMES OP DISCHARGE. Maximum stage recorded 14.0 feet at 5.30 p. m. October 23, 1914. (discharge, 4,700 second-feet); minimum stage recorded, 2.0 feet 

January 28 and 10 days in February (discharge, 100 second-feet).

WINTER FLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. No information.

REGULATION. Diurnal fluctuations in low-water flow are caused by pumping deep 

wells for city water works.

ACCURACY. Rating curve well defined; results good.

COOPERATION. Some discharge measurements furnished by the State Board of Water 

Engineers.

NTJECES RIVER BASIN. 

NUECES RIVER NEAR CINONIA, TEX.

LOCATION. At suspension highway bridge near Oswald's ranch, 2 miles east of Cinonia, Zavalla County, 8 miles northeast of Crystal City, 20 miles above the Winter 

Garden ranch dam.

DRAINAGE AREA. 2,060 square miles.

RECORDS AVAILABLE. July 5 to September 30, 1915.

GAGE. Vertical staff, in several sections, on both banks, just below the highway 

bridge; read twice daily by C. C. Oswald.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge or by wading 

about 100 feet below bridge.

CHANNEL AND CONTROL. Bed composed of clay and gravel; free from vegetation; 

shifts. Both banks high and wooded; neither is subject to overflow. Channel 

straight above and below station. Position of control not known. Stage-discharge relation seriously affected at times by backwater due to logs, leaves, and 

brush that collect below the gage.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 20.0 feet at 6.30 

a. m. September 19 (discharge not computed); minimum stage, 2.0 feet at. 6.30 

a. m., September 14 (discharge, 10 second-feet).

WINTER FLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. Considerable water diverted from stream above station for irrigation; 

amount not known.

REGULATION. Records indicate that flow above station is not regulated, but a dam 

40 feet high has been constructed about 20 miles below, and backwater from this 

dam, when the reservoir is full, extends to a point 2 miles below the station. A 

large part of the flow of the river sinks into the bed just below Uvalde and returns 

to the surface just above the station. The condition of the underground waters 

may have an effect upon this return water, and thus produce a regulating effect.

ACCURACY. Results fair; condition of stage-discharge relation somewhat uncertain; 

gage-height record subject to errors due to careless observations.

COOPERATION. Station established and records prior to September 1 collectedby 

State Board of Water Engineers.

The following discharge measurement was made by R. C. Thaxton: 

June 18, 1915: Gage height, 3.04 feet; discharge, 30 second-feet.

Daily discharge, in second-feet, of Nueces River near Cinonia, Tex., for the year ending

28 SUBFACE WATIEE SUPPLY, 1915, PAET VIII.

NUECES RIVER NEAR COTULLA, TEX.

LOCATION. At Hargus dam, 4 miles west of Cotulla, La Salle County.

DRAINAGE AREA. 5,030 square miles.

RECORDS AVAILABLE. July 1 to September 30, 1915.

GAGE. Vertical staff attached to trees on right bank; just above the dam; read daily 

by J. L. Hutchason.

DISCHARGE MEASUREMENTS. Made by wading below dam.

CHANNEL AND CONTROL. Bed composed of gravel, rock, and sand; general channel 

straight above and below the (station. Both banks wooded, of medium height, 

and not subject to overflow. Long concrete dam just below gage serves as control.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.2 feet at 1.40 

p. m. August 29 (discharge, 5,040 Becond-feet). No flow July 1 to August 8, 

August 15 and 16, and September 12-15.

WINTER FLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. Much of normal flow above station pumped or diverted for irrigation. 

Station is in upper end of section near Cotulla, in which considerable land is 

irrigated. In the First Report of the State Board of Water Engineers of Texas, 

two large filings are listed in the name of Winter Garden Irrigation Co. and 

Nueces Valley Irrigation Co., in Zavalla and Dimmit counties, the irrigable area 

under each system comprising 10,000 acres, the capacities of diversion works 

being 95.0 and 6.65 second-feet, respectively.

REGULATION. Flow regulated by storage reservoirs and pumping plants above station. No water-power plants above station.

ACCURACY. Results poor. Discharge measurements can not be made at high stages. 

Rating curve based on low-water discharge measurements and discharge determined by considering the dam as weir and using weir formula. Stage-discharge 

relation permanent; determination of discharge probably within 20 per cent of 

true discharge.

COOPERATION. Station established and records prior to September 1 collected by 

State Board of Water Engineers. .

The following discharge measurement was made by R. C. Thaxton: 

August 17, 1915: Gage height, 0.22 foot; discharge, 10 second-feet.

2 miles southeast of Three Rivers, Live Oak County, half a mile below mouth of 

Frio River.

DRAINAGE AREA. 15,600 square miles.

RECORDS AVAILABLE. July 1 to September 30, 1915.

GAGE. Vertical staff attached to center pier of railroad bridge, left abutment; read 

once daily by J. B. Smith.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge or by wading 

below bridge.

CHANNEL AND CONTROL. Bed composed of adobe shale; clean and not subject to 

extreme shifting. Channel straight above and below station. Banks high and 

 Wooded and not subject to overflow. Position of high-water control not known; 

shoal just below station is believed to be low-water control.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 10.3 feet at 6 p. m. 

September 23 (discharge, 2,170 second-feet); minimum discharge estimated 

0.2 second-foot, August 14 (gage height not accurately determined).

WINTER FLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. Considerable land is irrigated above station, but there is apparently 

no irrigable land immediately above.

REGULATION. Flow regulated somewhat by storage reservoirs and pumping in drainage basin above station, but the effect is not so pronounced as at stations in upper 

part of drainage basin. Existing water-power plants in drainage basin above 

station probably small.

ACCURACY. Results fair; rating curve fairly well defined. Recorded gage heights 

slightly erroneous because of the assumption that one daily reading represents 

the mean stage and also because of carelessness on part of gage reader.

COOPERATION. Station established and records prior to September 1 collected by the 

State Board of Water Engineers.

NOTE. Discharge determined from a fairly well defined rating curve developed in 1916. Discharge 

July 2 and Aug. 11-14 estimated from information furnished by hydrographers. Gage not read Aug. 27-29: 

information furnished by gage reader indicates that discharge exceeded 2,000 second-feet. Mean discharge 

for July, -7.67 second-feet; run-off, 470 acre-feet. Mean discharge for September, 914 second-feet; run-off, 

54,400 acre-feet.

NUECES RIVER AT CALAIXEN, TEX.

LOCATION. At the old pump house for the city of Corpus Ohristi, half a mile northwest 

of Calallen, Nueces County, 18 miles west of Corpus Christi, 8 miles above Nueces 

Bay, half a mile above edge of tidewater and the breakwater dam.

DRAINAGE AREA. 16,700 square miles.

RECORDS AVAILABLE. August 12 to September 30, 1915.

GAGE. Vertical staff attached to pipe-line support at old pump house; read twice 

daily by Henry Wagner.

DISCHARGE MEASUREMENTS. Made by wading at the breakwater or from cable 125 

feet below gage.

CHANNEL AND CONTROL. Channel straight above and below station, Left bank 

wooded, low, and bordered by levee constructed to prevent overflow; right bank 

wooded, of medium height, and not subject to overflow. Bed composed of clay 

and gravel. The breakwater, which is a loose rock fill half a mile below gage, 

serves as a control.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 3.70 feet at 4 p. m. 

August 31 and at 9.15 p. m. September 1 (discharge, 2,010 second-feet); minimum 

stage, 0.60 foot August 20-22 (discharge, 18 second-feet).

WINTER PLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. Considerable water diverted for irrigation just above station. The 

city of Corpus Christi pumps water at the gage for municipal supply and has 

made a filing with the State Board of Water Engineers for continuous use of 

0.93 second-foot and a storage of 675 acre-feet per annum. This pumping plant 

is between the breakwater and gage, and at low stages corrections are made for 

the amount pumped during current-meter measurements. A second small pump 

for private use is installed between the city intake and the breakwater but it 

is seldom operated. The quantity pumped is small and does not greatly affect 

the natural flow at ordinary stage.

REGULATION. Some water is diverted or pumped for irrigation above station; flow 

slightly regulated thereby. No water-power plants of consequence above station.

ACCURACY. Results fair. Base data reliable and accurate. Leakage through breakwater slightly changes the stage-discharge relation. Low-water discharge 

measurements are made with great difficulty on account of poor measuring sections. In determining daily discharge consideration has been given the effect 

of rising and falling stages.

COOPERATION. Station established and records prior to September 1 collected by 

State Board of Water Engineers.

NOTE. Discharge determined as follows: Aug. 12-25 by indirect method for shifting control; Aug. 26 to 

Sept. 30 from two well-defined rating curves based on discharge measurements made in 1916 during rising 

and falling stages. Mean discharge Aug. 12-31,341 second-feet (13,500 acre-feet); September,895second-feet 

(53,300 acre-feet).

FRIO RIVER NEAR DERBY, TEX.

LOCATION. At International & Great Northern Railway bridge 900 feet below mouth 

of Leona River, 4 miles south of Derby, Frio County.

DRAINAGE AREA. 3,500 square miles.

RECORDS AVAILABLE. August 1 to September 30, 1915.

GAGE. Vertical staff attached to railway bridge pier; read twice daily by John Speed.

DISCHARGE MEASUREMENTS. Made from railway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of rock, sand, and gravel; channel curved 

above and below station but straight at gage for 150 feet. Both banks high, 

wooded, and not subject to overflow. A concrete dam about 50 feet below the 

gage serves as a control during low and medium stages; position of high-water 

control not known. Point of zero flow, gage height 0.12 foot.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 7.9 feet at 8 a. m. 

September 18 (discharge, 3,020 second-feet). No flow August 1-28 and September 5-17.

WINTER FLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. Small areas are irrigated by diversion and pumping at headwaters, 

but so far as known water is not taken from stream immediately above station.

REGULATION. None above station.

ACCURACY. Results fair. Determinations subject to error due to the assumption 

that one gage reading daily represents the mean for the day. Stage-discharge 

relation practically permanent.

COOPERATION. Station established and records during August collected by State 

Board of Water Engineers.

No discharge measurements were made during the year.

BIO GRANDE BASIN. 

RIO GRANDE AT EMBTJDO, N. MEX.

LOCATION. Near sec. 27, T. 23 N., R. 9 E., 100 feet below the Santa Barbara Tie & 

Pole Co.'s bridge, a few hundred feet below the Denver & Rio Grande Railroad 

eating house at Embudo, a short distance above the mouth of the box canyon, in 

the southeastern part of Rio Arriba County. Nearest tributary, Embudo Creek, 

joins the Rio Grande about 3 miles above the station.

DRAINAGE AREA. Approximately 10,100 square miles.

RECORDS AVAILABLE. December 21, 1888, to December 31, 1903; September 8, 1912, 

to September 30, 1915.

GAGE. Friez water-stage recorder on right bank. From January 1 to February 28, 

1889, an inclined staff gage was maintained 1 mile above Embudo, but it was 

moved to a point 1,500 feet above the Santa Barbara Tie & Pole Co.'s bridge 

March 1, 1899, and used until December 31, 1903. The relation of these gages is 

unknown, but the datum remained unchanged from March 1, 1889, to December 

31, 1903. A Friez water-stage recorder, referred to a new datum, was installed 

September 8, 1912, on the downstream side of the Santa Barbara Tie & Pole 

Co.'s bridge pier, and this gage was operated until June 20, 1914, when it was 

moved to the present site. The datum has remained unchanged since the station was reestablished in 1912. Observer, H. W. Wallace. 

* DISCHARGE MEASUREMENTS. Made by wading or from cable just below gage.

CHANNEL AND CONTROL. Bed composed of rock, gravel, and sand; shifts at extremely 

high stages. Both banks high and not subject to overflow. Shoal just below gage 

serves as control.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 8.5 feet May 19 

(discharge, 10,000 second-feet); minimum stage recorded, 2.26 feet August 28 

(discharge, 386 second-feet). 

1888-1903; 1912-1915: Maximum stage recorded, 15.8 feet June 19, 1903 (discharge 15,900 second-feet); minimum stage recorded, 6.6 feet June 13, 1899 (discharge, 65 second-feet).

WINTER FLOW. Stage-discharge relation not seriously affected by ice.

DIVERSIONS. Between the Colorado-New Mexico State line and Embudo the river 

flows through a canyon and water is diverted only for irrigation in the small areas 

bordering the stream; above the State line and along the tributaries entering the 

Rio Grande in the canyon large areas of land are irrigated by diversions.
36 SURFACE WATER SUPPLY, 1915, PART VIII.

REGULATION. Low-water flow slightly regulated by diversions for irrigation above 

station. No storage is used in connection with the mill operated at Glenwoody, 

and the flow at the station is not regulated from that plant.

ACCURACY. Results good. Rating curve well defined. Stage-discharge relation not 

seriously affected by changes in control, and errors from that source are believed 

to be small.

COOPERATION. Discharge measurements made in January, February, and on March 

19 furnished by the State engineer of New Mexico.

RIO GRANDE NEAR BUCKMAN, N. MEX.i

LOCATION. About sec. 18, T. 19 N., R. 8 E., at the Denver & Rio Grande Railroad 

bridge 2 miles below the Indian village of San Ildefonso, 4 miles above Buckman, 

in the northwestern part of Santa Fe County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. February 1, 1895, to December 31, 1905; June 22, 1909, to 

December 31, 1914, when station was discontinued.

GAGE. Stevens water-stage recorder attached to downstream side of right bridge pier. 

An inclined staff gage for low-water readings and vertical staff gage for high-water 

readings were installed February 3,1895, on left bank about 180 feet above railroad 

bridge. On March 30, 1904, this gage was replaced by a vertical staff attached to 

downstream side of north bridge pier and referred to a datum 2.02 feet higher 

than original datum. On October 29, 1904, a chain gage, referred to second gage 

datum, was installed on the downstream side of the railroad bridge. During 1904, 

owing to changes in channel, readings were made on old and new gages at irregular 

intervals. The chain gage was read during 1905. From June 22, 1909, to June, 

1910, readings were made on the vertical staff gage attached to bridge pier. A 

Friez water-stage recorder was installed at the site of the vertical staff gage and 

referred to same datum in June, 1910, and was operated until April 16,1911; May 

4,1911, it was replaced by a Barrett & Lawrence water-stage recorder. On October 

13, 1914, a Stevens water-stage recorder was installed in place of the Barrett & Lawrence recorder at the same site. The datum has remained unchanged since 1904.

DISCHARGE MEASUREMENTS. Made by wading or from cable 3 miles below gage. 

No diversions or important tributaries between the two points.

CHANNEL AND CONTROL. Both banks high and not subject to overflow. Bed composed of sand and gravel; subject to change during low stages. Shoal about 500 

feet below gage serves as a control.

EXTREMES OP DISCHARGE. Maximum discharge during the year, 2,560 second-feet, 

October 5; minimum stage recorded, 2.95 feet December 13 and 14 (discharge, 428 

second-feet).

1895-1905; 1909-1914: Maximum stage recorded, 11.4 feet May 23, 1912 (discharge, 23,800 second-feet); minimum stage recorded, 0.60 foot August 23 and 24, 

1905 (discharge, 40 second-feet).

WINTER PLOW. Stage-discharge relation not seriously affected by ice.

1 In previous reports this station was designated as "near Rio Grande" and "at Watertank."
SURFACE WATER SUPPLY, 1915, PART VIII.

DIVERSIONS. Between Embudoand this station the bottom lands in Espanola Valley 

are irrigated extensively, quantity of water diverted not known. Considerable 

water is also diverted from tributaries above station for irrigation of valley lands.

REGULATION. The operation of mill at Glenwoody has no effect on the flow at the 

station. Flow is somewhat regulated by diversions for irrigation, especially 

during the summer.

ACCURACY. Results good. Stage-discharge relation permanent during high and 

medium stages and changes in low-water channel have been determined by 

frequent current-meter measurements.

RIO GRANDE NEAR SAN MARCIAL, N. MEX.

LOCATION. In sec. 19, T. 7 S., R. 1 W., at the Atchison, Topeka & Santa Fe Railway 

bridge 1 mile south of San Marcial, in the eastern part of Socorro County. No 

important tributaries enter in the immediate vicinity of the station.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. January 29, 1895, to September 30, 1915.
RIO GRANDE BASIN. 39

GAGE. Stage is measured from the bridge deck to the water surface with a graduated 

rod. An inclined staff gage established January 29, 1895, was carried away by a 

flood in 1896. A wire gage, referred to same datum, waa established soon after 

this flood but was abandoned. Datum unchanged since station was established.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

CHANNEL AND CONTROL. Bed composed of sand and gravel; no apparent control.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 14.2 feet April 18 

(discharge, 12,615 second-feet); minimum stage recorded, 8.6 feet September 16 

(discharge, 5 second-feet).

1895-1915: Maximum stage recorded, 13.75 feet October 11, 1904 (discharge, 

33,000 second-feet). The records show that there was no flow in the river during 

several extended periods since the station was established.

WINTER PLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. Large areas of bottom lands below Embudo, especially in the vicinity 

of Albuquerque, are irrigated; quantity of water diverted not known.

REGULATION. No controlling works above station that affect flow at this point.

ACCURACY. Owing to the shifting channel, determinations of discharge are based 

almost entirely on frequent current-meter measurements.

COOPERATION. Records furnished by the United States Reclamation Service.

RIO GRANDE NEAR EL PASO, TEX.

LOCATION. At Courchesne's limekiln, 1 mile upstream from pumping house of the

Smelter Co., 3 miles north of El Paso, in El Paso County. 

DRAINAGE AREA. Not measured. 

RECORDS AVAILABLE. May 10, 1889, to June 30, 1893, for station at old Fort Bliss,

about 1,500 feet above the Mexican dam; January 25, 1895, to May 1, 1897, for

station at pumping house of the Smelter Co.; May 1, 1897, to June 8, 1915, for

present site.
EIO GRANDE BASIN. 41

GAGE. A number of inclined gages have been used, located at slightly different points 

but referred to same datum. Gage at original site a vertical staff.

DISCHARGE MEASUREMENTS. Made from cable.

CHANNEL AND CONTROL. Extremely shifting; banks subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during period October 1, 1914, 

to June 8, 1915, 12.0 feet June 8 (discharge, about 5,000 second-feet); minimum 

stage recorded, 7.9 feet March 19 (discharge, 65 second-feet).

1889-1893,1895-1915: Maximum mean daily discharge, 23,680 second-feet, June

. 12, 1905. River reported dry nearly every year.

WINTER FLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. Many small diversions above station. The United States Reclamation 

Service has constructed a reservoir at Elephant Butte, N. Mex., to store water to 

be used in irrigating land in the Rio Grande Valley and storage of water was begun in March, 1915. The capacity of this reservoir is 2,627,700 acre-feet. The 

entire project was dedicated in October, 1916.

ACCURACY. Owing to the shifting channel, determinations of discharge are based 

almost entirely on current-meter measurements made very frequently.

COOPERATION. From May 1, 1897, to March 31, 1914, station maintained and records 

furnished by United States section of the International Water Commission; since 

August 1,1914, by Commission for the Equitable Distribution of the Waters of the 

Rio Grande.

RIO GRANDE BELOW PRESIDIO, TEX.

LOCATION. At the west end of the canyon section of the Rio Grande, 6 miles below 

Presidio, in Presidio County, and 7 miles below mouth of Bio Conchos.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 1, 1900, to July 31, 1915.

GAGE. Inclined staff in main channel and vertical staff at the gravel hills to measure 

overflow.

DISCHARGE MEASUREMENTS. Made in main channel from cable and in overflow 

section from boat.
EIO GRANDE BASIN. 43

CHANNEL AND CONTROL. Shifting sand. An intermittent stream, called Alamito 

Creek, which reaches the river a quarter of a mile below station, is subject to 

torrential floods which bring into the Rio Grande large quantities of boulders 

and gravel. The material forms a temporary dam that remains and causes backwater at the gage until it is scoured out by a flood in the river. At gage height 

13 feet the water overflows the banks and spreads to the gravel hills, reaching an 

extreme width of 750 feet.

EXTREMES OP DISCHARGE. Maximum stage recorded October 1, 1914, to July 31, 

1915, 12.1 feet October 1 (discharge about 6,000 feet); minimum stage recorded, 

7.2 feet April 26-28 (discharge, 65 second-feet).

1900-1915: Maximum stage recorded, 26.35 feet September 11,1904 (discharge,

149,200 second-feet); minimum mean daily discharge May 4-14,1904,5 second-feet.

Below the mouth of the Rio Conchos the Rio Grande is subject to severe floods

from that tributary. On September 11,1904, the discharge above the Rio Conchos

was only 2,600 second-feet.

DIVERSIONS. No data.

ACCURACY. Owing to shifting control, determinations of daily discharge are based 

almost directly on frequent current-meter measurements.

COOPERATION. Station maintained and records furnished by United States section 

of the International Water Commission until March 31,1914; after August 10,1914, 

by Commission for the Equitable Distribution of the Waters of the Rio Grande.

Discharge measurements of Rio Grande below Presidio, Tex., during the year ending

SURFACE WATER SUPPLY, 1915, PART VIII.

RIO PUEBLO DE TAGS NEAR TAGS, N. HEX.

LOCATION. Near sec. 2, T. 25 N., R. 13 E., at Glorietta Grove, 2 miles above Taos 

Pueblo, 4| miles northeast of Taos, near center of Taos County. A number of 

intermittent tributaries enter above and below station.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. December 19, 1910, to September 30, 1915. Fragmentary 

records March to December, 1910.

GAGE. Bristol water-stage recorder on right bank a short distance above Glorietta 

Grove; installed December 19, 1910. Vertical staff gage installed April 7, 1910, 

was destroyed by flood before July 12, 1910, and on October 12, 1910, a new gage 

was installed at same site at a datum 0.27 foot lower than that of original gage; 

water-stage recorder at same datum as second gage.

DISCHARGE MEASUREMENTS. Made by wading.

CHANNEL AND CONTROL. Bed composed of rock and gravel; water flows through a 

series of pools and rapids. Banks low but are seldom overflowed as discharge is 

small. Control appears to be subject to slight changes, especially during high

EXTREMES OP DISCHARGE Maximum stage recorded during year, 3.55 feet May 14

and 15 (discharge, 260 second-feet); minimum stage recorded, 0.90 foot February

13; discharge, 5.0 second-feet. 

1910-1915: Maximum stage recorded, 4.55 feet May 22, 1912 (discharge, 440

second-feet); minimum discharge, 5.0 second-feet several days during January,

1914, and February 13, 1915. 

WINTER PLOW. Stage-discharge relation seriously affected by ice; flow estimated

from current-meter measurements, obesrver's notes, and records of precipitation

and temperature i

DIVERSIONS. None above station but several just below. 

REGULATION. None. 

ACCURACY. Results good. The slight changes in stage-discharge relation do not

greatly affect accuracy of determinations. 

COOPERATION. Records of current-meter measurements made in February furnished

by State engineer of New Mexico.

58 SURFACE WATER SUPPLY, 1915, PART VIII.

RIO LTJCERO HEAR TAGS, K. MEX.

LOCATION. In sec. 11, T. 26 N., R. 13 E., just above head gate of Seco ditch, at 

mouth of canyon, 9 miles above Taos, near center of Taos County. No important 

tributaries near station.

DRAINAGE AREA. 17 square miles (measured by United States Indian Service).

RECORDS AVAILABLE. December 17, 1910, to September 30, 1915. Fragmentary 

records from March to October, 1910. 

GAGE. Bristol water-stage recorder installed on right bank December 17, 1910, at 

same site and datum as original gage installed April 7, 1910.

DISCHARGE MEASUREMENTS. Made by wading.

CHANNEL AND CONTROL. Bed composed of rock, gravel, and sand; water flows through 

a series of pools and rapids. Banks of medium height but not subject to overflow as discharge is email. Position of control unknown but shifting.

EXTREMES OP DISCHARGE. Maximum stage recorded during the year and the period 

1910-1915, 2.25 feet June 12, 1915 (discharge, 174 second-feet); minimum stage 

recorded, 0.25 foot (ice) March 7 and 8, 1915 (discharge, 4.5 second-feet).

WINTER FLOW. Stage-discharge relation seriously affected by ice; flow estimated 

from current-meter measurements, observer's notes, and records of precipitation 

and temperature.

DIVERSIONS. None above station; below station water is diverted for irrigation.

REGULATION. No power plants or controlling works above station.

ACCURACY. Results fair. Changes in stage-discharge relation, due to effect of ice, 

impair accuracy of winter records. Gage should be read to hundredths to insure 

accurate determination of discharge of a stream the size of this, but water-stage 

recorder will not give readings closer than half-tenths.

COOPERATION. Record of current-meter measurement made in February furnished 

by State engineer of New Mexico.

60 SURFACE WATER SUPPLY, 1915, PART VIII.

RIO FERNANDO DE TAOS NEAR TAOS, N. HEX.

LOCATION. In sec. 21, T. 25 N., R. 13 E., 200 yards upstream from the head gate of 

E.G. Randall's ditch, at mouth of canyon, 2 miles southeast of Taos, near center 

of Taos County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 5, 1912, to July 31, 1915, when station was discontinued. Fragmentary records April 6, 1910. to October 4, 1912.

GAGE. Vertical staff on left bank just above wagon-road ford; read daily by Sadie 

Witt.

DISCHARGE MEASURMENTS. Made by wading.

CHANNEL AND CONTROL. Bed composed of gravel and sand; shifts during high 

stages; water flows in a series of pools and rapids. Banks not likely to overflow 

as discharge of stream is small. Position of control not known.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.20 feet at 6 p. m. 

April 30 (discharge, 118 second-feet); minimum stage recorded, 0.88 foot December 3 (discharge, 1.2 second-feet).

1910-1915: Maximum stage recorded April 30,1915 (see preceding paragraph); 

minimum determined discharge, 0.2 second-foot, Augxist 30, 1913.

WINTER FLOW. Stage-discharge relation not seriously affected by ice, formation of 

which is prevented by springs just above gage.

DIVERSIONS. Only very small quantities of water diverted above station; several 

diversions below.

REGULATIONS. No water-power plants or controlling works above station.

ACCURACY. Results good. Stage-discharge relation subject to change during high 

stages, but usually the change is not great, as the ordinary flow is small. The 

stream being unregulated, one gage reading each day under normal conditions 

shows the mean stage and flow within the necessary degree of accuracy.

COOPERATION. Record of current-meter measurements made in January, February, 

and March furnished by State engineer of New Mexico.

Discharge measurements of Ftio Fernando de Taos, near Taos, N. Mex., during the year

ending Sept. 30, 1915.

62 SURFACE WATER SUPPLY, 1915, PART VIII.

CHAMA RIVER NEAR GHANA, N. MEX.

LOCATION. In sec. 25, T. 31 N., R. 3 E., in the northern part of Rio Arriba County, 

at highway bridge on main road from Chama to Tierra Amarilla, 200 feet above 

mouth of Little Chama River, 2£ miles southeast of Chama.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 27, 1914, to September 30, 1915. From September 23, 

1912, to May 26,1914, a station was maintained on Chama River at Chama, 2 

miles upstream; intervening tributaries unimportant.

GAGE. Stevens water-stage recorder attached to downstream side of right pier of 

bridge.

DISCHARGE MEASUREMENTS. Made by wading or from highway bridge.

CHANNEL AND CONTROL. Bed composed of sand, gravel, and rock; shifts only during 

extremely high stages. Banks are of medium height and are overflowed at 

extremely high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.95 feet at 11 

p. m., May 15 (discharge, computed from extension of rating curve, 1,430 secondfeet); minimum stage recorded, 1.75 feet (ice) December 9 (discharge, 19 secondfeet).

WINTER FLOW. Stage-discharge relation seriously affected by ice; flow estimated 

from current-meter measurements, observer's notes, and records of precipitation and temperature.

DIVERSIONS. The city ditch diverts approximately 2 second-feet above the station 

from June to September.

REGULATION. None.

ACCURACY. Results fair for open season and poor for winter period. Flow is somewhat erratic at this point, but stage-discharge relation is permanent during 

ordinary stages and changes cause little error in determinations.

COOPERATION. Record of current-meter measurements made in January and February furnished by State engineer of New Mexico.

Discharge measurements of Chama River near Chama, N. Mex., during the year ending

Sept. 30, 1915.

SURFACE WATER SUPPLY, 1915, PART VIII.

CHAMA RIVER AT PARK VIEW, N. MEX.

LOCATION. In sec. 7, T. 29 N., R. 4 E., at highway bridge half a mile northwest of 

Park View, about 800 feet below confluence of Brazos and Chama rivers in northcentral part of Rio Arriba County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. November 25, 1912, to September 30, 1915.

GAGE. Friez water-stage recorder attached to downstream side of right pier of bridge. 

During 1912 and 1913 the recorder was attached to the downstream side of right 

abutment of bridge, but it was moved to the present site because of changes in 

channel in 1914. Original datum remains unchanged.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Bed composed of large cobblestones, sand, and gravel; 

shifts extremely during high stages. Right bank high and not subject to overflow; 

left bank is low and is overflowed during extremely high stages. Control is at 

rapids 100 feet below gage.

EXTREMES or DISCHARGE. 1912-1915: Maximum stage recorded, 6.03 feet at 11 p. m. 

May 16, 1915 (discharge, computed from extension of rating curve, 3,290 secondfeet); minimum stage recorded, 3.05 feet September 24, 1915 (discharge, 16 

second-feet).

WINTER FLOW. Stage-discharge relation seriously affected by ice; flow estimated 

from current-meter measurements, observer's notes, and records of precipitation 

and temperature.

DIVERSIONS. Between Chama and Park View approximately 8 second-feet diverted 

from Chama River and 16 second-feet from intervening tributaries during 

irrigation season.

REGULATION. No water-power plants above station.

ACCURACY. Results poor for winter period and fair for open-water season. Accuracy 

of determinations impaired by changes in stage-discharge relation due to severe 

effect of ice and shifts in control during extremely high stages.

COOPERATION. Record of current-meter measurement made in January and February furnished by State engineer of New Mexico.

66 SURFACE WATER SUPPLY, 1915, PART VIII.

CHAMA RIVER NEAR EL VADO.i N. MEX.

LOCATION. At the mouth of box canyon below El Vado Valley, 1 mile southeast 

of El Vado, 15 miles southwest of Tierra Amarilla, near center of Rio Arriba 

County. Nutrias Creek, which is the south line of the Tierra Amarilla land 

grant, joins Chama River from the north 4 miles below station.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 28, 1913, to September 30, 1915.

GAGE. Stevens water-stage recorder attached to rock wall on right bank.

DISCHARGE MEASUREMENTS. Made by wading or from cable just above gage.

CHANNEL AND CONTROL. Bed composed of solid rock and gravel; changes are very 

slight. Both banks high and not subject to overflow. Control is rock reef just 

below gage.

EXTREMES OF DISCHARGE. 1913-1915: Maximum,"8.30 feet at 2.30 a. m. May 17, 

1915 (discharge, 4,030 second-feet, estimated from extension of rating curve); 

minimum stage recorded, 0.10 foot September 20-24,1915 (discharge, 28 secondfeet).

WINTER FLOW. Stage-discharge relation seriously affected by ice; flow estimated 

from current-meter measurements, records of flow at near-by stations, and records 

of temperature and precipitation.

DIVERSIONS. Between Park View and this station approximately 3 second-feet 

diverted from Chama River and 2 second-feet from intervening tributaries during irrigation season.

REGULATION . None.

ACCURACY. Results for open-water season good; those for winter period poor, as 

stage-discharge relation is seriously affected by ice. Small errors introduced 

by the slight changes in channel probably do not materially affect the determinations.

COOPERATION. Record of current-meter measurements made in January furnished 

by State engineer of New Mexico.

BRAZOS RIVER NEAR BRAZOS, N. HEX.

LOCATION. At mouth of box canyon 3 miles east of Brazos, 15 miles southeast of 

Chama, in northern part of Rio Arriba County, 1J miles above mouth of Little 

Brazos River.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 18, 1913, to September 30, 1915.

GAGE. Friez water-stage recorder on left bank.

DISCHARGE MEASUREMENTS. Made by wading or from cable near gage.

CHANNEL AND CONTROL. Bed composed of rock, gravel, and sand; changes slightly 

at high stages. Both banks of medium height and not subject to overflow except 

during extremely high stages.

WINTER FLOW. Stage-discharge relation seriously affected by ice; flow estimated 

from current-meter measurements, records of flow at near-by stations, and records 

of precipitation and temperature.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.39 feet at 8 p. m. 

May 14 (discharge computed from extension of rating curve, 3,240 second-feet); 

minimum discharge obtained, 25 second-feet during parts of December.

1913-1915: Maximum stage recorded May 14,1915; minimum, 0.49 foot October 

26, 1913 (discharge, 18 second-feet). The stream also carried 18 second-feet during parts of December, 1913, but the stage-discharge relation was affected, by ice.

DIVERSIONS. None above station; approximately 8 second-feet diverted below during irrigation season.

REGULATION . None.

ACCURACY. Results good for open-water season, as stage-discharge relation is per 

manent during low and medium stages; results for winter season poor.

COOPERATION. Record of current-meter measurements made in January and February furnished by State engineer of New Mexico.

RIO VALLECITOS AT VALLECITOS, N. MEX.

LOCATION. In sec. 17, T. 26 N., R. 8 E., at Vallecitos, in the Carson National Forest, 

eastern part of Rio Arriba County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. June 17, 1911, to December 31, 1914, when station was discontinued.

GAGE. Vertical staff attached to tree on left bank; read occasionally by D. G. 

Darrah, forest ranger.

DISCHARGE MEASUREMENTS. Made by wading.

CHANNEL AND CONTROL. Bed composed of rock, gravel, and sand; permanent. 

Shoal below gage probably serves as control.

EXTREMES or DISCHARGE. 1911-1914: Maximum stage recorded, 4.65 feet May 21, 

1912 (discharge, 970 second-feet); minimum stage recorded, 0.83 foot September 

17, 1914 (discharge, 2.3 second-feet).

WINTER FLOW. Stage-discharge relation seriously affected by ice; flow estimated 

from observer's notes and records of precipitation and temperature.

DIVERSIONS. Small quantities of water are diverted for irrigation for a distance of 6 

miles above station.

REGULATION. None at this point.

ACCURACY. Results poor. Estimates of discharge for days on which gage was read 

considered good, but the error introduced by interpolation for those days on 

which gage heights are missing lowers the accuracy of results as a whole. Stagedischarge relation practically permanent. 

No current-meter measurements made during year.

SANTA FE CHEEK ABOVE RESERVOIR NEAR SANTA FE, N. MEX.

LOCATION. In sec. 22, T. 17 N., R. 10 E., a quarter of a mile above Santa Fe Water 

& Light Co.'s diversion for water supply, 1J miles above reservoir, 5 miles east of 

Santa Fe, in eastern part of Santa Fe County.

DRAINAGE AREA. 22.5 square miles (measured on topographic map).

RECORDS AVAILABLE. April 24, 1913, to December 31, 1914, when station was discontinued. Fragmentary records May 12, 1910, to April 23, 1913, from a station 

one mile below present gage and below diversion of Santa Fe Water & Light Co.

GAGE. Stevens water-stage recorder attached to rock wall on right bank, installed 

April 24, 1913.

DISCHARGE MEASUREMENTS. Made by wading or from cable just above old site 1 mile 

downstream.

CHANNEL AND CONTROL. Bed composed of sand and gravel. Banks high and not 

subject to overflow. An artificial concrete control was constructed October 24, 

1913, just below the gage, with zero flow at gage height 1.0 foot; stage-discharge 

relation constant during low and medium stages since that date. Position of highwater control unknown. Prior to installation of artificial control stage-discharge 

relation was subject to change.

EXTREMES OF DISCHARGE. Maximum stage recorded 1913 and 1914, 2.82 feet (maintained for 30 minutes), June 16, 1914 (discharge computed from slope and cross 

section applied to Kutter's formula, 226 second-feet); minimum stage recorded, 

1.18 feet January 27, 1914 (discharge, 1.7 second-feet).

WINTER FLOW. Stage-discharge relation affected by ice; flow estimated from currentmeter measurements, gage-height record, and records of precipitation and temperature.

DIVERSIONS. None above station but considerable water is diverted below.

REGULATION. None at this point.

ACCURACY. Results excellent for open-water season and fair for winter period; the 

artificial control is effective throughout the ordinary range of flow; change in 

stage-discharge relation at higher stages small.

RIO PUERCO AT RIO PUERCO, N. MEX.

LOCATION. In sec. 31, T. 7 N., R. 1 W., at Atchison, Topeka & Santa Fe Railway 

bridge between Dalies and Rio Puerco, in eastern part of Valencia County. Nearest tributary, a small stream entering from west just below station; San Jose River 

enters about 8 miles above.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. August 9, 1912, to December 31, 1914, when station was discontinued; fragmentary records September 7,1910, to October 2,1911.

GAGE. Vertical staff gage attached to railway retaining wall on left bank directly 

under railway bridge; read morning and evening, by Goldie Barber. Previous to 

1913, Friez and Barrett & Lawrence water-stage recorders were used at various 

times. Vertical staff gages were used at site of water-stage recorder without change 

in datum until August 21,1914, when datum was lowered 3.14 feet.
RIO GRANDE BASIF. 79

DISCHAEGE MEASUREMENTS. Made by wading or from cable about 200 feet above

gage. 

CHANNEL AND CONTROL. Bed composed of clay and sand; subject to extreme changes.

Banks consist of clay; nearly vertical and not subject to overflow. Position of

control not known. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 5.90 feet October

4 (discharge, 1,230 second-feet); no flow October 1,16, and 17.

1910-11; 1912-1914: Maximum stage recorded, 9.50 feet October 5, 1913 (discharge not computed). Channel dry at various times throughout period of record. 

WINTER FLOW. Stage-discharge relation not seriously affected by ice. 

DIVERSIONS. Some water diverted above station for irrigation; amount not known. 

REGULATION . None. No water-power plant above station. 

ACCURACY. Results approximate. The stage-discharge relation changes constantly

because of the erratic flow. The assumption that average of two observations a

day is the mean stage for that day also leads to error.

SAN JOSE RIVER NEAR SUWANEE, N. MEX.

LOCATION. Near sec. 29, T. 8 N., R. 2 W., 2 miles below Suwanee railroad station, 

about 6 miles above mouth of river, 3 miles below Bio Lucero, in eastern part of 

Valencia County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. August 30, 1910, to December 31, 1914, when station was 

discontinued. Records prior to October 1, 1912, fragmentary.

GAGE. Stevens water-stage recorder attached to rock wall on left bank, April 1,1914, 

replacing a Barrett & Lawrence water-stage recorder installed in 1911 and operated until that date. Friez water-stage recorder was installed September 6,1910. 

Datum and site unchanged since station was established.

DISCHARGE MEASUREMENTS. Made by wading or from cable a short distance above

CHANNEL AND CONTROL. Bed composed of large bowlders, gravel, and sand; water

flows through a series of pools and rapids. Banks high and not subject to overflow.

The channel confined by a large rock, causing rapids, just below the gage serves

as a control, but is subject to slight changes during extreme stages. 

EXTREMES OF DISCHARGE. 1910-1914: Maximum stage recorded, 6.20 feet August 17,

1911 (discharge not computed); no flow March 1-9, 1912, and December 17-31,

1912. 

WINTER FLOW. Stage-discharge relation not affected by ice, the formation of which

is prevented by springs above gage. 

DIVERSIONS. Station is below all important diversions; amount of water diverted

unknown. y 

REGULATION. Low-stage flow derived from springs. No water-power plants above

station indicated by records. 

ACCURACY. Results good; slight changes in stage-discharge relation do not greatly

affect accuracy of determinations.

PECOS RIVER NEAR COWLES, N. MEX.

LOCATION. About sec. 28, T. 18 N., R. 12 E., at highway bridge three-fourths mile 

below old Cowles post office, 5 miles below present Cowles post office, midway 

between Espiritu Santo and Mora creeks, about half a mile below mouth of Willow Creek, in northwestern part of San Miguel County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. March 9, 1910, to December 31, 1914, when the station was 

discontinued.

GAGE. Friez water-stage recorder installed on left bank April 18, 1913. Friez 

recorder March 9, 1910, to June 4, 1912; Bristol recorder June 5, 1912, to April 

9, 1913. Site and datum unchanged since station was established.

DISCHARGE MEASUREMENTS. Made by wading or from highway bridge.

CHANNEL AND CONTROL. Bed composed of gravel and rock; permanent at ordinary 

stages. Banks high and not subject to overflow. Stage-discharge relation 

changes slightly during high water.

EXTREMES OP DICHARGE. 1910-1914: Maximum stage recorded, 5.30 feet May 27, 

1912 (discharge, 1,800 second-feet); minimum stage recorded, 1.00 foot (ice) January 20, 1913 (discharge, 18 second-feet).

WINTER PLOW. Stage-discharge relation seriously affected by ice; flow estimated 

from current-meter measurements, observer's notes, and records of precipitation 

and temperature.

DIVERSIONS. Little, if any, water diverted above station.

REGULATION. None at this point.

ACCURACY. Results poor for winter and good for open-water season. Slight changes 

in stage-discharge relation during open-water season are caused by high water. 

Accuracy of determination of winter flow impaired by uncertainty of operation 

of the water-stage recorder when ice forms.

PECOS RIVER AT SANTA ROSA, N. HEX.

LOCATION. In sec. 11, T. 8 N.} R. 21 E., at highway-bridge at Santa Rosa, 1 mile 

above mouth of Rio Agua Negra Chiquita, 6 miles above Canyon Pintada, in northcentral part of Guadalupe County.

DRAINAGE AREA. 2,780 square miles (measured on land office map).

RECORDS AVAILABLE. February 1, 1910, to July 31, 1911; September 21, 1912, to 

December 31, 1914, when station was discontinued. From May 5, 1903, to 

December 31, 1906, records were obtained by United States Reclamation Service 

at a station 400 feet upstream.

GAGE. Chain gage attached to downstream side of highway bridge; installed February 3, 1910, and set to read the same as the staff gage on the pier of the Chicago, 

Rock Island & El Paso Railway bridge 400 feet farther upstream, which was used 

by the United States Reclamation Service from May 5, 1903, to December 31, 

1906. Datum of gages differed by an unknown amount, equal to slope of water 

surface at that time. Gage read morning and evening by George H. Smith, jr.

DISCHARGE MEASUREMENTS. Made by wading or from highway bridge.

CHANNEL AND CONTROL. Bed composed of sand and gravel; extremely shifting. 

Position of control unknown. Banks high and not subject to overflow.

EXTREMES OF DISCHARGE. 1903-1906,1910-11,1912-1915: Maximum stage recorded, 

23.0 feet September 30,1904 (discharge not computed); minimum stage recorded, 

1.45 feet April 5-8, 1910 (discharge, 5.0 second-feet).

WINTER FLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. No information.

REGULATION. No power plants above station.

ACCURACY. Results fair. Stage-discharge relation changes constantly; frequent 

current-meter measurements necessary to insure accurate determination.

Low and medium stage flow at this point depends on return seepage; at such stages 

the water disappears some distance above station, reappearing in the vicinity of gage 

from springs in the bed and banks.

PECOS RIVER NEAR GUADALUPE, N. MEX.

*

LOCATION. In sec. 34, T. 5 N., R. 24 E., 500 feet below l mouth of Alamo Gordo Creek, 

half a mile above the Alamo dam site, 4 miles west of Fort Sumner-Santa Rosa 

road, 8 miles above Guadalupe post office, 17 miles northwest of Fort Sumner, in 

southeastern part of Guadalupe County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 11, 1912, to December 31, 1914. when station was 

discontinued.

GAGE. Friez water-stage recorder on left bank; replaced a Barrett & Lawrence 

water-stage recorder in 1913

DISCHARGE MEASUREMENTS. Made by wading or from cable a short distance downstream from gage.

CHANNEL AND CONTROL. Bed composed of rock, sand, and gravel; shifting; a shoal 

exists just below gage. Banks high and not subject to overflow. Apparently 

no permanent control.

EXTREMES OF DISCHARGE. 1912-1914: Maximum stage recorded, 15.5 feet May 1, 

1914 (discharge, computed from extension of rating curve, 42,000 second-feet); 

minimum stage recorded, 0.51 foot August 14, 1913 (discharge, 57 second-feet).

WINTER PLOW. Stage-discharge relation slightly affected by ice at times.

DIVERSIONS. Large quantities of water diverted for irrigation above station; effect 

reduced to a small extent by water returned by seepage above station.

REGULATION. No water-power plants above station.

ACCURACY. Results good. Changes in stage-discharge relation, due to changes in 

channel, probably do not greatly impair the accuracy of the determinations.

PECOS RIVER NEAR DAYTON, N. HEX.

LOCATION. In sec. 13, T. 18 S., R. 26 E., 3 miles east of Dayton, half a mile above 

mouth of Penasco River, in northwestern part of Eddy County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. March 24, 1905, to September 30, 1915.

GAGE. Stevens water-stage recorder installed on right bank August 27, 1914, at same 

site and datum as staff gage installed September 7, 1905. Original gage 100 feet 

below the mouth of Penasco River, half a mile below present gage was destroyed 

September 6, 1905.

DISCHARGE MEASUREMENTS. Made from cable.

CHANNEL AND CONTROL. Bed composed of sand and gravel; shifting, especially during high stages. Right bank is clay and left bank sand; both banks are subject 

to overflow during extremely high stages. No well-defined control.

EXTREMES OF DISCHARGE. Maximum discharge obtained during year, 42,000 secondfeet April 18; gage height not known. Minimum stage recorded, 2.42 feet October 13; discharge, 74 second-feet.

1905-1915: Maximum discharge obtained, 50,300 second-feet July 25, 1905 

(gage height not known). Minimum stage recorded, 2.40 feet October 16, 1908 

(discharge, 28 second-feet).

WINTER PLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. Considerable water diverted above station for irrigable valley lands; 

quantity so diverted not known, but the diversion does not conflict with the 

rights of the Carlsbad project of the United States Reclamation Service, which 

serves about 20,000 acres in the vicinity of Carlsbad and stores a portion of the 

water used near Carlsbad in Lake McMillan; 10 miles below the gage.

REGULATION . None.
BIO GEANDE BASIN. 89

ACCURACY. Results fair. Frequent current-meter measurements are necessary to 

insure accurate determinations, as stage-discharge relation is changeable.

COOPERATION. Records April 15 to 19 and July 1 to September 30 furnished by United

PECOS RIVER AT CARLSBAD, N. HEX.

LOCATION. In the SE. i sec. 6, T. 22 S., R. 27 E., at Green Street Bridge in Carlsbad, 300 feet downstream from Atchison, Topeka & Santa Fe Railway station, 

1,500 feet above mouth of Dark Canyon, 2,000 feet below Hagerman dam, near 

center of Eddy County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 28, 1903, to March 31, 1908; May 18, 1914, to September 

30, 1915.

GAGE. Vertical staff, attached to the upstream side of middle bridge pier, installed 

May 18, 1914; read twice daily by D. Armendariz. Gage used from May 28,

1903. to October, 1904, was an inclined staff gage, and that used from October,

1904. to March 31,1908, a vertical staff gage at same site.

DISCHARGE MEASUREMENTS. Made by wading or from bridge.

CHANNEL AND CONTROL. Bed composed of gravel and rock; nearly permanent, 

though changes may occur after high stages, and slight changes have taken place 

during lower stages. Position of control not known. Banks of medium height; 

not subject to overflow.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 20.5 feet April 

17 (discharge not computed); minimum stage recorded, 0.80 foot January 10-12 

and 21 (discharge, 60 second-feet).

1903-1908 and 1914-15: Maximum stage recorded, April 17, 1915; minimum 

stage recorded, zero (no flow), May 9, 1904.

WINTER FLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. Water stored by United States Reclamation Service in Lakes McMillan 

and Avalon, a few miles above station, is used to irrigate lands near Carlsbad. 

Capacity of storage reservoirs in connection with the Carlsbad project, 58,500 

acre-feet. Water is also diverted for irrigation in the valleys adjacent to the 

river above Lake McMillan.

REGULATION. Flow at this point completely controlled by the storage reservoirs of 

the Carlsbad project.

ACCURACY. Results fair. Considerable water seeps into river between the reservoirs 

and gaging station, the quantity depending on the quantity of water being used for 

irrigation between the two points. Stage fluctuates with quantity of water released at the reservoirs and returned by seepage, so that the assumption that 

the average of two gage readings a day is the mean stage for that day probably 

subjects the determination to considerable error. Stage-discharge relation practically permanent, but no current-meter measurements were made during latter 

part of year.

EVAPORATION NEAR CARLSBAD, N. HEX.

A station to determine evaporation was established July 31, 1914, at the head gates 

on Lake Avalon, on the Carlsbad project of the United States Reclamation Service, 

about 6 miles north of Carlsbad and 3,200 feet above sea level.

The equipment consists of a standard rain gage and a heavy galvanized iron pan, 3 

feet square and 18 inches deep, floating on the reservoir. The water surface in the 

pan is kept at approximately the same level as that outside the pan, the quantity of 

water that must be added to the pan daily to preserve that level being used as a 

measure of evaporation, allowance being made for the amount of rainfall.

RIO GEANDE BASIN. 93

PECOS RIVER NEAR ANGELES, TEX.

LOCATION. In T. 26 S., R. 29 E., just below the Pecos Valley Railroad Bridge across 

Delaware Creek at its mouth, 2 miles north of New Mexico-Texas State line, 2J 

miles southeast of Red Bluff, N. Mex., 8J miles northwest of Angeles, Tex., near 

south line of Eddy County, N. Mex.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 27, 1914, to September 30, 1915.

GAGE. Stevens continuous water-stage recorder over a vertical float box driftbolted 

to the first outcrop of rock on right bank about 600 feet below railroad bridge and 

mouth of Delaware Creek.

DISCHARGE MEASUREMENTS. Made by wading or from cable about half a mile 

below gage.

CHANNEL AND CONTROL. Bed and banks of the river composed of sand, gravel, and 

rock; banks are not subject to overflow. Control is formed by a series of rapids 

about 200 feet below the gage; shifts slightly.

EXTREMES OF DISCHARGE. Maximum stage during 1914 and 1915 from water-stage 

recorder, 15.45 feet at 11 a. m. April 17, 1915 (discharge, 54,900 second-feet), 

computed from extension of rating curve and may be subject to considerable 

error; minimum stage recorded, 0.24 foot at 10 p. m. July 6, 1915 (discharge, 128 

second-feet).

WINTER FLOW. Stage-discharge relation not seriously affected by ice; open-channel 

rating curve assumed applicable.

DIVERSIONS. The Carlsbad project of the United States Reclamation Service, with 

reservoirs of a capacity of 58,500 acre-feet, diverts a large part of the natural run-off 

above Carlsbad, N. Mex. During the season of irrigation considerable water is 

returned to the stream by seepage from the lands in the vicinity of Carlsbad. In 

addition to the water used by the Carlsbad project, some water is diverted for 

irrigation in the basin above the storage reservoirs of the Carlsbad project.

REGULATION. The operation of a 300-horsepower water-power plant above the station 

just below Carlsbad does not materially affect the flow at the gage. The flow is, 

however, regulated to a large extent by water stored in the reservoirs of the Carlsbad project, and during the winter the flow is dependent on the water released at 

those reservoirs. During the season of irrigation return seepage waters decrease 

the effect of regulation.

ACCURACY. Results good; channel and control subject to slight changes; station well 

rated for low and medium stages.

EIO GEANDE BASIN. 95

PECOS RIVER NEAR BARSTOW, TEX.

LOCATION. Near northeast corner of water tract No. 10, sec. 34, Ward County, 2J 

miles above mouth of Toyah Creek, 4 miles southeast of Barstow, 5 miles above 

diversion for Big Valley project and 7 miles downstream from Texas & Pacific 

Railway bridge.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 27, 1914, to August 11, 1915, when station was discontinued.

GAGE. Stevens water-stage recorder on left bank used April 27, 1914, to May 16, 

1915; May 17 to August 11, 1915 vertical staff gage 100 feet below recorder, and at 

same datum; read daily by C. P. Maulding.

DISCHARGE MEASUREMENTS. Made by wading or from cable 100 feet below gage.

CHANNEL AND CONTROL .---Bed composed of sand and gravel. Banks clay; subject 

to overflow at extremely high stages, so that the stream spreads over an area 

about a mile in width. No permanent control; discharge relation changes continually during changes in stage.

EXTREMES OF DISCHARGE. 1914-15: Maximum stage recorded, 12.5 feet during 

afternoon of April 20, 1915, determined by leveling from flood marks (discharge 

not computed); minimum stage recorded, less than 20 second-feet from July 1 to 

28, 1915.

WINTER FLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. Water in large quantities is stored in the reservoirs of the Carlsbad 

project of the United States Reclamation Service, having a total capacity of 

58,500 acre-feet, and also utilized by direct diversion from river above station. 

Large areas are irrigated in the vicinity of Barstow.

REGULATION. Flow regulated to a large extent by storage reservoirs in the drainage 

area above the station. The return of water to the stream by seepage above and 

below the station during the irrigating season tends to reduce partly the direct 

effect of regulation. The operation of a 300-horsepower water-power plant on 

Pecos River below Carlsbad, N. MexM produces no observable effect at the station.

ACCURACY. Results poor; stage-discharge relation changeable; gage-height record 

not complete.

EIO GRANDE BASIN. 97

PECOS RIVER NEAR COMSTOCK, TEX.'

LOCATION. At the Pecos high bridge of Galveston, Harrisburg & San Antonio, Railway Co. (Southern Pacific lines). 11 miles west of Comstock, 18 miles east of 

Langtry, 14 miles by stream above confluence with Rio Grande, in western part 

of Valverde County; below all tributaries.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 1, 1900, to September 30, 1915. Also gage heights for 

1898.

GAGE Vertical staff attached to the downstream side of bridge pier on left bank; 

read twice daily by W. A. Clare.

DISCHARGE MEASUREMENTS. Made from cable 1,000 feet above bridge.

CHANNEL AND CONTROL. Banks and bed composed of rock and gravel; stream flows 

through a series of rapids and pools in a canyon aboat 300 feet deep. The stagedischarge relation at the lower stages changes frequently.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 19.0 feet, October 

23 (discharge, 36,700 second-feet); minimum stage recorded, 0.80 foot during parts 

of July, August, and September (discharge. 366 second-feet).

1900-1915: Maximum stage recorded, 35.75 feet, April 6, 1900 (dircharge not 

computed); minimum stage recorded, 0.50 foot, May, 1904 (discharge, 110 secondfeet).

WINTER PLOW. Stage-discharge relation not affected by ice.

DIVERSIONS AND STORAGE. Consideraole water is diverted and stored above the 

station for irrigation. Lake McMillan and Lake Avalon, on the Carlsbad project 

of the United States Reclamation Service, with a combined capacity of 58,500 

acre-feet, are on Pecos River a few miles above Carlsbad, N. Mex. Large areas 

of land are irrigated by water diverted from Pecos River in the vicinity of Barstow 

and Grandfalls, Tex. No diversions below station.

REGULATION. Yearly run-off at this point controlled by storage and diversions for 

irrigation above, but return waters eliminate a partial effect of the diurnal change 

in the lower part of the drainage. No large water-power plants in the drainage 

basin except a public-utility plant of about 300 horsepower, near Carlsbad, 

N. Mex., which does not affect the flow at this point.

ACCURACY. Results fair. Determinations are subject to slight errors due to diurnal 

fluctuation and the assumption that the average of two readings a day is the 

mean for that day, but the largest errors are due to changes in stage-discharge 

relation at low stages.

GALLINAS RIVER NEAR LAS VEGAS, N. HEX.

LOCATION. Near sec. 1, T. 16 N., R. 15 E., at Las Vegas Hot Springs, 6 miles northwest of Las Vegas, in northwestern part of San Miguel County. No tributaries 

between station and Las Vegas nor for several miles above.

DRAINAGE AREA. 89 square miles (measured on topographic map).

RECORDS AVAILABLE. August 13,1903, to May 31,1912; December 1,1912, to December 31, 1914, when station was discontinued.
RIO GRANDE BASIN. 99

GAGE. Vertical staff attached to retaining wall on right bank at the Hot Springs; 

read morning and evening; installed October 19, 1904, to replace a vertical staff 

at same site destroyed September 29, 1904. Datum was lowered 0.71 foot October 19, 1904.

DISCHARGE MEASUREMENTS. Made by wading or from footbridge 600 feet below gage.

CHANNEL AND CONTROL. Bed composed of rock and gravel; water flows through a 

series of pools and rapids. Banks high and not subject to overflow. Control 

shifts especially during the higher stages; position not known.

EXTREMES OP DISCHARGE. 1903-1914: Maximum discharge obtained, .11,600 second-feet September 29, 1904, computed by Kutter's formula from measurements 

of slope and cross section; no flow during several periods.

WINTER PLOW. Stage-discharge relation not affected by ice; channel kept open by 

hot springs.

DIVERSIONS. The Agua Pura Co. has diverted waters at a point about 1J miles above 

station, for storage since February, 1913. Water is also furnished by this company 

at a second small diversion to the city of Las Vegas and the Santa Fe Railway. 

A short distance above the station is a timber dam formimg a pond from which ice 

is cut; this dam has slight effect on the flow. A mile below the station is a dam 

at which the flood flow of the Gallinas is diverted to the San Guyillo basin. The 

fall of the river is so great that the gaging station is above backwater from this dam.

REGULATION. No power plants above station.

ACCURACY. Results good. Stage during the period of record is well covered by current-meter measurements, and the stage-discharge relation has been permanent. 

Fluctuations in stage during the irrigation season introduce errors due to the 

assumption that the average of two readings per day is the mean for that day, but 

such errors probably do not materially impair the accuracy of the determinations 

here published.

SOUTH FORK OF GAIXINAS RIVER NEAR EL FORVENIR, N. HEX.

LOCATION. Near sec. 14, T. 17 N., R. 14 E., at the Gallinas planting station of the 

United States Forest Service, in the Pecos National Forest, 1 mile south of El 

Porvenir post office, 2| miles above junction of North and South Forks, in northwestern part of San Miguel County. Nearest tributary is a small stream entering 

from the north a short distance above.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 9, 1911, to December 31, 1914, when station was discontinued.

GAGE. Vertical staff, read morning and evening by Herman Krauch.

DISCHARGE MEASUREMENTS. Made by wading.

CHANNEL AND CONTROL. Bed composed of rock.and gravel; shifts slightly. Banks 

not subject to overflow, as discharge is small. Position of control unknown.

EXTREMES OP DISCHARGE. 1911-1914: Maximum stage recorded, 4.24 feet, October 

5, 1911 (discharge, 226 second-feet); minimum stage recorded, 1.15 feet, June 26 

and 29, 1911 discharge, 1.2 second-feet).

WINTER PLOW. Stage-discharge relation seriously affected by ice; flow estimated from 

current-meter measurements, observer's notes, and records of precipitation and 

temperature.

DIVERSIONS. No diversions above, except an intermittent one of less than half a 

second-foot. Just below the gage the United States Forest Service maintains a 

ditch of 3 second-feet capacity.

REGULATION. None at this point.

ACCURACY. Results good for the open-water season and fair for the winter season. 

Effect of ice on stage-discharge relation greatly impairs the accuracy of determination of winter discharge. Errors introduced by the slight changes in stagedischarge relation during the open-water period are small.

BLACK RIVER NEAR MALAGA, N. MEX.

LOCATION. In the NW. i NE. J sec. 10, T. 24 S., R. 28 E., at highway bridge on the 

Malaga-Loving road, 400 feet downstream from Pecos Valley Lines (Santa Fe 

Route), 1 mile north of Malaga, about 1£ miles above confluence with Pecos River, 

in the southern part of Eddy County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 1, 1914, to June 30, 1915, when station was discontinued.

GAGE. Inclined staff, for low stages, fastened to left bank, and vertical staff attached 

to left abutment of bridge for high stages; read morning and evening by Frank 

Beeman.

DISCHARGE MEASUREMENTS. Made by wading or from highway bridge.

CHANNEL AND CONTROL. Bed composed of sand, gravel, and rock; water flows in 

series of pools and rapids; bed not subject to extreme changes though stagedischarge relation varies slightly. Banks high and not likely to overflow. Rapids 

a short distance below gage serve as control.

EXTREMES OP DISCHARGE. 1914-15: Maximum stage recorded, 11.0 feet April 17, 

1915 (discharge not computed); minimum stage recorded, 0.85 foot May 3 and 27, 

and October 7, 1914, and May 7, 27, and 29, 1915 (discharge, 3.5 second-feet).

WINTER PLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. Considerable water diverted above station; amount not known; no 

diversions below station.

REGULATION. No power plants in the drainage basin.

ACCURACY. Results fair. Stage-discharge relation is practically permanent, but 

determinations are subject to errors arising from the assumption that the average 

of two readings a day is the mean stage for that day.

DELAWARE RIVER NEAR ANGELES, TEX.

LOCATION. In T. 26 N., R. 29 E. New Mexico principal meridian, 1 mile above 

confluence with Pecos River, 2J miles south of Red Bluff, N. Mex., about 3 miles 

north of New Mexico-Texas State line, 10 miles northwest of Angeles, Tex., in 

the southern part of Eddy County, N. Mex.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 26, 1914, to June 19, 1915, when station was discontinued.

GAGE. Stevens water-stage recorder on right bank.

DISCHARGE MEASUREMENTS. Made by wading or from cable half a mile below gage.

CHANNEL AND CONTROL. Bed composed of sand and gravel through which rock 

outcrops. Banks high and not subject to overflow. A shoal about 100 feet below 

the gage serves as a control but it shifts during extremely high stages.

EXTREMES OF DISCHARGE. 1914-15: Maximum stage recorded, 4.21 feet April 17, 

1915 (discharge not computed); minimum discharge, 0.1 second-foot May 18-20 

and May 28 to June 4, 1915.

WINTER PLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. A large part of the flow is diverted above station for irrigating lands 

of Coad's ranch. No diversions below.

REGULATION . None.

ACCURACY. Results fair for first part of the year but poor during latter part, as 

changes in channel prevented the proper operation of the water-stage recorder.

MIMBRES RIVER BASIN. 

MIMBRES RIVER NEAR FAYWOOD, N. MEX.

LOCATION. In sec. 7, T. 20 S., E. 10 W., 400 feet below dam site of Rio Mimbres 

reservoir, about 6 miles northeast of Faywood Hot Springs, 10 miles north of 

Faywood, a station on the Silver City branch of the Atchison, Topeka & Santa 

Fe Railway, in northeastern part of Grant County.

DRAINAGE AREA. Approximately 450 square miles.
INTERIOR BASINS IN NEW MEXICO. 105

RECORDS AVAILABLE. April 8,1908, to December 31, 1914, when station was discontinued.

GAGE. Friez water-stage recorder on right bank. From April 8, 1908, to August 12, 

1909, readings were taken with a chain gage on right bank 200 feet downstream. 

On July 8, 1909. datum of chain gage was lowered 4 feet. The recorder was 

installed August 13, 1909, at a datum 1 foot lower than original datum.

DISCHARGE MEASUREMENTS. Made by wading or from cable a short distance below

CHANNEL AND CONTROL. Bed composed of sand and gravel; shifts. Banks clay and 

gravel; right bank high and not subject to overflow; left bank is sloping and is 

overflowed at extremely high stages. Position of control not known.

EXTREMES OP DISCHARGE. 1908-1914: Maximum discharge estimated at 2,200 secondfeet, July 23, 1914; no flow for extended periods since establishment of station.

WINTER PLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. Some water diverted for irrigation above and below station; amount 

unknown.

REGULATION. None at this point.

ACCURACY. Results poor, errors being introduced into the determinations by changeability in the stage-discharge relation and also by rapid fluctuations in stage during current-meter measurements.

The following discharge measurement was made by E. L. Redding: 

November 5, 1914: Gage height, 0.50 foot; discharge, 25.1 second-feet.

106 SURFACE WATER SUPPLY, 1915, PART VIII.

LAMPBRIGHT DRAW NEAR SANTA RITA, N. MEX.

LOCATION. In sec. 19, T. 18 S., R. 11 W., at mouth of box canyon, 5| miles southeast 

of Santa Rita, in eastern part of Grant County. Rustlers Canyon enters Lampbright Draw about 2 miles above station and Martin Canyon about 3J miles Lelow.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. August 20, 1912, to December 31, 1914, when station was 

discontinned.

GAGE. Friez water-stage recorder attached to rock wall on right bank.

DISCHARGE MEASUREMENTS. Made by wading or from cable just below gage.

CHANNEL AND CONTROL. Bed composed of solid rock with pockets of sand and 

gravel; shifts. Both banks high and not subject to overflow. Position of control 

unknown.

EXTREMES OP DISCHARGE. 1912-1914: Maximum stage recorded, 6.1 feet July 20, 

1914 (discharge not computed). Discharge 0.10 second-foot during parts of July, 

1913, and November, June, and July, 1914.

WINTER PLOW. Stage-discharge relation not affected by ice.

DIVERSIONS. Only small quantities of water diverted from stream above station.

REGULATION. None at this point.

ACCURACY. Results poor. Stage-discharge relation is changeable and the erratic 

flow of the stream made it difficult to obtain the data necessary for a complete 

rating.

The following discharge measurement was made by E. L. Redding: 

December 22, 1914: Gage height 0.92 foot; discharge, 186 second-feet.

Daily discharge, in second-feet, of Lampbright Draw near Santa Rita, N. Mex., for the

year ending Sept. 30, 1915.

RIO TULAROSA BASIN.

RIO TULAROSA NEAR TULAROSA, N. MEX.

LOCATION. In sec. 21, T. 14 S., R. 10 E., about half a mile above the head gate of

Tularosa irrigation ditch, 3 miles above Tularosa, in northern part of Otero County. 

DRAINAGE AREA; Not measured. 

RECORDS AVAILABLE. December 2, 1912, to December 31, 1914, when station was

discontinued. 

GAGE. Vertical staff on left bank. Read twice daily by Fred Montoya. July 17,

1914, datum of gage was lowered 2 feet to avoid negative readings. 

DISCHARGE MEASUREMENTS. Made by wading. 

CHANNEL AND CONTROL. Bed composed of sand, gravel, and rock, with a shoal

just below the gage; shifts. Banks consist of rock; not subject to overflow.

Control apparently unstable. 

EXTREMES OP DISCHARGE. 1912-1914: Maximum stage recorded, 8.00 feet July 2,

1914 (discharge not computed); minimum stage recorded, 1.20 feet July 15, 1913

(discharge, 2.5 second-feet).

WINTER PLOW. Stage-discharge relation not seriously affected by ice. 

DIVERSIONS. Some water diverted for irrigation above station; amount not known. 

REGULATION. Flow slightly regulated by diversions for irrigation above station. 

ACCURACY. Results fair; impaired by changeable stage-discharge relation.

The following discharge measurement was made by R. J. Hank: 

December 5, 1914, gage height, 1.15 feet; discharge, 14.0 second-feet.

STREAM-GAGING STATIONS

AND

PUBLICATIONS RELATING TO WATER RESOURCES

PART VIII WESTERN GULF OF MEXICO 

DRAINAGE BASINS
\
STREAI-GAGING STATIONS AND PUBLICATIONS RELATING TO WATER RESOURCES.

INTRODUCTION.

Investigation of water resources by the United States Geological 

Survey has consisted in large part of measurements of the volume 

of flow of streams and studies of the conditions affecting that flow, 

but it has comprised also investigation of such closely allied subjects 

as irrigation, water storage, water powers, underground waters, and 

quality of waters. Most of the results of these investigations have 

been published in the series of water-supply papers, but some have 

appeared in the bulletins, professional papers, annual reports, and

NOTE. No data regarding stream flow are given in the 15th and 17th annual reports.

The records at most of the stations discussed in these reports 

extend over a series of years, and miscellaneous measurements at 

many points other than regular gaging stations have been made 

each year. An index of the reports containing records obtained 

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

The table below gives, by years and drainage basins, the numbers of the papers on surface-water supply published from 1899 to 

1913. The data for any particular station will in general be found 

in the reports covering the years during which the station was maintained. For example, data for Machias River at Whitneyville, Maine, 

1903 to 1915, are published in Water-Supply Papers 97, 124, 165, 

201, 241, 261, 281, 301, 321, 351, 381, and 401, which contain records 

for the New England streams from 1903 to 1915. Kesults of miscellaneous measurements are published by drainage basins.

In these papers and in the following lists the stations are arranged 

in downstream order. The main stem of any river is determined 

by measuring or estimating its drainage area that is, the headwater 

stream having the largest drainage area is considered the continuation of the main stream, and local changes in name and lake surface 

are disregarded. AH stations from the source to the mouth of the 

main stem of the river are presented first, and the tributaries in 

regular order from source to mouth follow, the streams in each 

tributary basin being listed before those of the next basin below.

The exceptions to this rule occur in the records for Mississippi 

River, which are given in four parts, as indicated on page in, and in 

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

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

forth over the lake surface.

PART VIII. WESTERN GULF OF MEXICO DRAINAGE

BASINS.

PRINCIPAL STREAMS.

The western Gulf of Mexico drainage basins include all streams 

draining into the Gulf of Mexico west of the mouth of the Mississippi and into the Rio Grande. The largest streams flowing into the 

Gulf of Mexico north of the mouth of the Rio Grande are Sabine, 

Trinity, and Brazos rivers, Colorado River of Texas, and Guadalupe 

River. The principal tributaries of the Rio Grande are Chama 

River, Rio Puerco, and Pecos River in the United States and Rio 

Salado and Rio San Juan in Mexico. The streams drain wholly or 

in part the States of Colorado, Louisiana, New Mexico, Texas, and 

northern States of Mexico.

In addition to the list of gaging stations and annotated list of publications relating specifically to the section, these pages contain a 

similar list of reports that are of general interest in many sections 

and cover a wide range of hydrologic subjects, and also brief references to reports published by State and other organizations. (See 

pp. xvi-xvn.)

GEOLOGIC FOLIOS.

Under the plan adopted for the preparation of a geologic map of the United States 

the entire area is divided into small quadrangles, bounded by certain meridians and 

parallels, and these quadrangles, which number several thousand, are separately 

surveyed and mapped. 1 The unit of survey is also the unit of publication, and the 

maps and description of each quadrangle are issued in the form of a folio. When all 

the folios are completed they will constitute the Geologic Atlas of the United States.

A folio is designated by the name of the principal town or of a prominent natural 

feature within the quadrangle. Each folio includes maps showing the topography, 

geology, underground structure, and mineral deposits of the area mapped and several 

pages of descriptive text. The text explains the maps and describes the topographic 

and geologic features of the country and its mineral products. The topographic map 

shows roads, railroads, waterways, and, by contour lines, the shapes of the hills and 

valleys and the height above sea level of all points in the quadrangle. The arealgeology map shows the distribution of the various rocks at the surface. The structuralgeology map shows the relations of the rocks to one another underground. The economic-geology map indicates the location of mineral deposits that are commercially 

valuable. The artesian-water map shows the depth to underground-water horizons. 

Economic-geology and artesian-water maps are included in folios if the conditions 

in the areas mapped warrant their publication. The folios are of special interest to 

students of geography and geology and are valuable as guides in the development and 

utilization of mineral resources.

The folios numbered from 1 to 163, inclusive, are published in only one form (18 

by 22 inches), called the library edition. Some of the folios that bear numbers higher 

than 163 are published also in an octavo edition (6 by 9 inches). Owing to a fire in 

the Geological Survey building May 18, 1913, the stock of geological folios was more 

or less damaged by fire and water, but 80 or 90 per cent of the folios are usable. They 

will be sold at the uniform price of 5 cents each, with no reduction for wholesale

1 Index maps showing areas in the western Gulf of Mexico basins covered by topographic maps and by 

geologic folios will be mailed on receipt of request addressed to the Director, U. S. Geological Survey,
