SURFACE WATER SUPPLY OF WESTERN GULF OF

MEXICO BASINS, 1917.

AUTHORIZATION AND SCOPE OF WORK.

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

measurements of flow made on streams in the United States during 

the year ending September 30, 1917.

The data presented in these reports were collected by the United 

States Geological Survey under the following authority contained in 

the organic law (20 State. L., p. 394):

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 

relating to irrigation in the arid west. 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 SO, 1895-1918.

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

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

1911 to 1918, inclusive.....-................................. 150,000

In the execution of the work many private and State organizations 

have cooperated either by furnishing data or by assisting in collecting 

data. Acknowledments 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 page 9.

Measurements of stream flow have been made at about 4,240 points 

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

Hawaiian Islands. In July, 1917, 1,180 gaging stations were being 

maintained by the Survey and the cooperating organizations. Many 

miscellaneous discharge measurements are made at other points. In

5
6 SURFACE WATER SUPPLY, 1911, PART VIII.

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 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, miners' 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, and acre-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.

"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 

run-off with rainfall, which is usually expressed in depth in 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.

The following terms not in common use are here defined:

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

of gage height to discharge."

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

stream channel 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.

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

on the gage the gage height to which the surface of the river falls 

when the discharge is reduced to zero.

SURFACE WATER SUPPLY, 1911, PART VIII. 7 

EXPLANATION OF DATA.

The data presented in this report cover the year beginning October 

1, 1916, and ending September 30, 1917. At the beginning 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 

run-off 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. (See Pis. I, II.) The general 

methods are outlined in standard textbooks on the measurement of 

river discharge.

From the discharge measurements rating tables are prepared that 

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

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

and yearly means of discharge are determined.

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

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

of discharge measurements, a table showing the daily discharge of 

the stream, and a table of monthly and yearly discharge and run-off.

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

tables giving daily gage height and records 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 permanence of the stage-discharge relation, 

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

for log driving, shifting of control, 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, in general, 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.
8 SURFACE WATER SUPPLY, 1917, PART VIII.

If such stations are equipped with water-stage recorders the mean 

daily discharge may be obtained by averaging discharge at regular intervals during the day, or by using the 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 

given in the maximum column. Likewise, in the column headed 

"Minimum" the quantity given is the mean flow for the day when 

the mean gage height was lowest. The column headed '' Mean'' is the 

average flow in cubic feet per second during the month. On this 

average flow computations recorded in the remaining columns, which 

are defined on pages 6, are based.

The deficiency table presented for some of the gaging stations 

shows the number of days in each year on which the mean daily 

discharge was less than the discharge given in the table. By subtraction the table gives the number of days each year that the mean 

daily discharge was between the discharges given in the table and, 

also by subtraction, the number of days that the mean daily discharge 

was equal to or greater than the discharge given. If one discharge 

rating table was used throughout the period covered by the deficiency 

table, gage heights that correspond to the discharges are also given.

ACCURACY OF FIELD DATA AND COMPUTED RECORDS.

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

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

of observation of stage, measurement of flow, and interpretation of 

records.

A paragraph in the description of the station gives information 

regarding the (1) permanence of the stage-discharge relation, (2) 

precision with which the discharge rating curve is defined, (3) refinement of gage readings, (4) frequency of gage readings, and (5) 

methods of applying daily gage height to the rating table to obtain 

the daily discharge.

For the rating tables "well defined" indicates, in general, that the 

rating is probably accurate within 5 per cent; "fairly well defined," 

within 10 per cent; "poorly denned," 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 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
OF WORK. 9

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.

COOPEBATION.

The work of measuring streams in Texas during the year ending 

September 30, 1917, was carried on in cooperation with the State 

through the Board of Water Engineers, consisting of James C. Nagle, 

chairman; John Wilson, and E. B. Gore.

The United States Reclamation Service and the United States 

Weather Bureau gave assistance to the work in Pecos River valley, 

Brazos River, and Colorado River basin, and upper Trinity basin by 

furnishing equipment, records, and giving general assistance. A 

large part of the equipment for the evaporation station near Austin 

was furnished by the United States Weather Bureau.

The cities of Corpus Christi, Brownwood, and Austin, the Cuero 

Commercial Club, the county of Comal, the San Marcos Utilities Co., 

the Imperial Irrigation Co., the Winter Garden Irrigation Co., the 

Arlington Land Co., the Kansas City, Mexico & Orient Railroad, the 

Pecos Valley lines, the Texas & Pacific Railway, the Gulf, Colorado 

& Sante Fe Railroad, and the International & Great Northern Railway have aided in collecting records by furnishing funds, or giving 

general assistance.

DIVISION OF WORK.

The data for stations in Texas and southeastern New Mexico, in 

the Pecos River basin, were collected and prepared for publication 

under the direction of Glenn A. Gray, district engineer, assisted by 

William Kessler, Russell J. Hank, Edgar O. Francisco, Edward P. 

Congdon, junior engineers; and R. C. Thaxton, Victor Lieb, and W. 

C. Dodd, State hydrographers.
10 SURFACE WATER SUPPLY, 191*7, PART VIII.

The field data for the Rio Grande drainage basin in New Mexico 

were collected under the direction of Robert Follansbee, district 

engineer, by G. S. Cowdrey, jr. Ratings and computations were 

made by S. B. Soule" and P. V. Hodges.

The manuscript was assembled and reviewed by W. E. Dickinson.

SURFACE WATER SUPPLY, PART VIII.

BRAZOS RIVER BASIN. 

BRAZOS RIVER NEAR GRAHAM, TEX.

LOCATION. At two-span steel highway bridge on Murray road, 6 miles above mouth 

of Clear Fork, 10 miles west of Graham, Young County.

DRAINAGE AREA. 12,900 square miles.

RECORDS AVAILABLE. November 13, 1915, to September 30, 1917.

GAGE. Vertical staff on left downstream corner of middle pier; read by Mrs. John 

Timmons.

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

CHANNEL AND CONTROL. Channel straight above and below station. Bed is composed of sand and clay; free from vegetation; shifting. Left bank high and not 

subject to overflow; right bank is of medium height and is overflowed during high

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 9.00 feet at 8 a. m. 

October 17 (discharge, 3,600 second-feet; determined from extension of rating 

curve and possibly subject to considerable error); no flow during several periods. 

1916-1917: Maximum stage recorded, 9.50 feet at 6 p. m. April 2, 1916 (discharge, 4,100 second-feet, determined from extension of rating curve, and possibly subject to considerable error); no flow during several periods.

ICE. Slight amount of ice reported in December and January.

DIVERSIONS. No information available to show that water is diverted above station 

in any large quantity for irrigation; no diversions between station and mouth of 

Clear Fork.

REGULATION. Number of power plants and controlling works above station not 

known; gage heights do not indicate that flow is regulated.

ACCURACY. Stage-discharge relation not permanent; not affected by ice during the 

year. Rating curve poorly defined. Gage read to hundredths twice daily. 

Daily discharge ascertained by applying mean daily gage height to rating table 

directly October 17 to July 4; and by shifting-control method October 1-16 

and July 5 to September 30. Discharge determinations above 2,000 second-feet 

obtained from an extension of rating curve; subject to considerable error. Records poor.

14 SUKFACE WATEK SUPPLY, 1917, PART VIII.

BRAZOS RIVER AT BRAZOS, TEX.

LOCATION. At Texas & Pacific Railway bridge half a mile northeast of Brazos, Palo 

Pinto County, 1J miles above mouth of Palo Pinto Creek.

DBAINAGE AREA\ 20,200 square miles (revised).

RECORDS AVAILABLE. October 1, 1914, to September 30, 1917. Records of stage 

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

GAGE. Vertical staff on northwest side of and one foot from upstream edge of pier 

nearest the middle of the railway bridge; graduations above 4 feet painted on the 

pier; read by L. W. Boyett.

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

below railway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of sand and gravel; shifts slightly. Right 

bank high, rocky, wooded, and not subject to overflow; left bank composed of 

sand, gravel, and clay, wooded, and medium in height, and subject to overflow 

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

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 6.50 feet at 6 p. m. 

October 18 (discharge, 9,400 second-feet); no flow April 7-14 and August 15-18. 

1908-1917: Maximum stage recorded, 22.0 feet May 24, 1908 (discharge not 

determined); no flow for several periods within period of records.

ICE. Slight amount of ice reported in December, January, and February.

DIVERSIONS. A few pumping plants have been installed along the stream for the 

purpose of irrigating small areas, but water so pumped will not greatly affect the 

flow of the stream.

REGULATION. Flow unaffected by power plants, dams, or reservoirs above or immediately below station. Swamps and natural lakes are rare in the drainage basin 

above the station.

ACCURACY. Stage-discharge relation not permanent. Two rating curves, fairly well 

denned below 2.8 feet gage height were used for the year, applicable respectively, 

October 1-16 and October 17 to September 30; high-water curve fairly well 

defined below 18,000 second-feet. Gage read to half-tenths twice daily. Daily 

discharge ascertained by applying daily gage height to rating table. Records fair.

16 SURFACE WATER SUPPLY, 1917, PART VIII.

BRAZOS RIVER AT WACO, TEX.

LOCATION. At suspension bridge on Bridge Street, in Waco, McLennan County, 

just below Southern Traction Co.'s bridge, 2J miles below mouth of Bosque 

River, 4J miles above mouth of Cottonwood Creek, about 9 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, 1917. Record of stage has 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 

southwest pier; read by A. E. Howell. Gage used from September 14, 1898, to 

February 29,1908, was an inclined staff gage under left end of bridge. In 1902 a 

gage agreeing in datum 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 for high-water readings. 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 reconstruction of suspension bridge, chain gage 

was on the one-span highway bridge. All gages were installed at same datum, 

but readings probably differ slightly because of differences in position.

DISCHARGES MEASUREMENT. Made from downstream side of first one-span highway 

bridge above station.

CHANNEL AND CONTROL. Bed 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. Lock No. 8 will eventually form the control; effect at present is very slight.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 14.32 feet at 

6.45 a. m. October 19 (discharge, 17,600 second-feet); minimum stage, 4.88 feet 

6.50 a. m. April 19 (discharge, 49 second-feet).

1898-1917: Maximum stage recorded, 39.7 feet December 3, 1913 (discharge 

not determined); minimum stage, 0.80 foot several days during February, June, 

and July, 1911 (discharge, 4 second-feet).

ICE. None reported during year.

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

station. Small areas of land are irrigated above station, but quantity of water 

diverted is only a smalL percentage of the total flow.

REGULATION. None of importance.

ACCURACY. Stage-discharge relation not permanent. Rating curve used as basis 

for ascertaining discharge by shifting-control method is fairly well defined. Gage 

read to quarter-tenths once daily. Slight error may be introduced by taking 

one daily gage reading as the mean for the day. Daily discharge ascertained by 

applying daily gage height to rating table directly, February 23 to April 29; by 

shifting-control method, October 1 to February 22, and April 30 to September 

30. Records fair.

CLEAR FORK OF BRAZOS RIVER NEAR ELIASVILLE, TEX.

LOCATION. At new suspension highway bridge 2J miles northeast of Eliasville, Young 

County, 4J miles southwest of South Bend, 6 miles above mouth of stream, and 

below all tributaries.

DRAINAGE AREA. 5,650 square miles.

RECORDS AVAILABLE. November 12, 1915, to September 30, 1917.

GAGE. Chain gage attached to downstream side of bridge; read by Alice Vaughn.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Banks high, wooded, composed of clay and gravel, and not 

subject to overflow. Bed composed of sand and gravel; free from vegetation. 

Channel straight above and below station. A shoal about 600 feet below station 

serves as control for low and medium stages; control shifts during changing stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 10.8 feet 5.15 p. m. 

October 18 (discharge, 2,710 second-feet); no flow during a large part of the year.

1916-17: Maximum stage recorded, 18.2 feet 6 p. m. May 2, 1916 (discharge, 

6,630 second-feet); no flow for extended periods.

ICE. None reported during year.

DIVERSIONS. Much of the land now irrigated above the station is in Jones and Taylor' 

counties; two diversions are made for irrigation between station and confluence of 

Clear Fork with Brazos River. Quantity of water diverted unknown. According 

to the Second Report of the Board of Water Engineers for the State of Texas, the 

Sweetwater Light & Power Co. has declared a storage of 216 acre-feet, and 

Abilene Water Co. a continuous use of 1.5 second-feet of water in the headwater region.
BKAZOS RIVER BASIN.

REGULATION. No large reservoirs above or below station. The operation of a water; 

power grist mill 5 miles upstream produces some effect at the station.

ACCURACY. Stage-discharge relation not permanent. Rating curve fairly well denned below 9,000 second-feet. Rating curve previously used for 1915-16 has 

been revised on account of high-water measurements made in 1918. Gage read 

to hundredths twice daily; observer's work not entirely satisfactory; mean daily 

gage height may not be true index of daily flow because of regulation for power. 

Daily discharge ascertained by applying mean daily gage heights to rating table: 

directly, November 12, 1915 to April 1, 1916, and May 2 to September 30, 1916 

by shifting control method, April 2 to May 1, 1916, and October 1, 1916 to September 30,1917. Records fair. 

Records of daily and monthly discharge for 1915-16, based on revised rating curve,

are published herewith, and supersede those previously published.

BRAZOS RIVER BASIN.

LITTLE RIVER AT CAMERON, TEX.

LOCATION. 200 feet below city pumping plant, half a mile south of Cameron, Milam 

County, 1 mile above Gulf, Colorado & Santa Fe Railway bridge, 6 miles below 

mouth of San Gabriel River, and 25 miles above confluence with Brazos River.

DRAINAGE AREA. 7,010 square miles (measured on topographic maps, Hill's map of 

Texas, and Post Route maps).

RECORDS AVAILABLE. November 1, 1916, to September 30, 1917.

GAGE. Vertical and inclined staff; three sections, attached to trees on left bank a 

short distance below home of pump man; read by Bert Petty.

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

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

normal flow and free from vegetation. Banks clay and gravel; medium height; 

wooded; subject to overflow only during extreme stages. Rock and gravel shoal 

100 feet below gage serves as control for low and medium stages; subject to change 

during flood stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 16.50 feet at 7 a. m. 

September 7,(discharge, 5,860 second-feet); minimum stage, 0.93 foot at 7 a. m. 

September 1 (discharge, 6.5 second-feet).

ICE. None reported during year.

DIVERSIONS. Small areas are irrigated in the upper drainage basin, but such diversions have little effect on flow at station. Second Report of the Board of Water 

Engineers for the State of Texas lists a filing by Cameron Power & Light Co. for 

continuous use of 5 second-feet with a declared consumption of 3,650 acre-feet 

per aTmum for waterworks, light, and power in Cameron. During times of low 

flow, water pumped by Cameron Power & Light Co. will affect the flow at this 

station.

REGULATION. None apparent beyond slight effect of pumping for city of Cameron.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined below 

13,000 second-feet by discharge measurements made in 1917 and 1918. Gage 

read to hundredths twice daily. Daily discharge ascertained by applying mean 

daily gage height to rating table. Records good.

COLORADO RIVER BASIN. 25

COLORADO RIVER AT BALLINGER, TEX.

LOCATION. At Hutchins Avenue highway bridge, 800 feet below Gulf, Colorado & 

Santa Fe Railway bridge in Ballinger, Runnels County, 1 mile above mouth 

of Elm Creek.

DRAINAGE AREA. 6,460 square miles (revised).

RECORDS AVAILABLE. December 11, 1915, to September 30, 1917. Records of 

stage have been obtained by the United States Weather Bureau since July 1, 

1903; current-meter measurements were be*gun May 29, 1915.

GAGE. Chain gage attached to downstream handrail of bridge; read by A. J. Voelkel.

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

CHANNEL AND CONTROL. Banks consist of clay and gravel; medium height and 

wooded; subject to overflow at extremely high stages. Bed composed 'of hard 

clay, sand and gravel; somewhat shifting. Control is shoal about 1,000 feet 

below gage; subject to change.

ICE. None reported during year.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 11.50 feet at noon 

October 17 (discharge not determined). No flow during several periods throughout year.

1916-17: Maximum stage recorded, October 17, 1916 (see preceding paragraph); 

minimum stage, no flow during several periods.

DIVERSIONS. During low stages a large part of the flow is diverted above the station 

by gravity or pumping. The Second Report of the Board of Water Engineers 

for the State of Texas shows 3,307 acres in Runnels County, above the station, 

to have been declared irrigated by use of 6,614 acre-feet of water. This report 

also shows filings by cities of Ballinger and Winters for continuous use of 1 and 

4 second-feet, respectively, for waterworks. The city of Ballinger started 

to pump water from river just above station the last of April, 1917, and continued to pump part of its supply therefrom throughout the summer.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent. Rating curve fairly well 

defined below 600 second-feet and extended above. Gage read to hundredths 

twice daily. Daily discharge ascertained by applying mean daily gage height 

to rating table: directly, June 3 to September 4; by shifting-control method, 

October 1 to June 2, and September 5-29. Discharge interpolated September 30. 

Records below 1,000 second-feet are fair; above that they may be subject to 

considerable error.

Sept. 30, 1917.

COLOBADO RIVER BASIN.

COLOBADO RIVER NEAR CHADWICK, TEX.

LOCATION. At Gulf, Colorado & Santa Fe Railway bridge half a mile below Chadwick dam, 1 mile above mouth of Elliott Creek, 2 miles west of Chadwick, on 

line between San Saba and Lampasas counties, 2J miles below mouth of San 

Saba River.

DRAINAGE AREA. 26,400 square miles.

RECORDS AVAILABLE. October 21, 1915, to September 30, 1917.

GAGE. Inclined staff in three sections, attached to rock ledge on left bank about 75 

feet upstream from railway bridge; read by A. G. Walker. A high-water section 

is painted on left face of left bridge pier. A vertical staff on right bank directly 

opposite inclined gage is used during low water. Gages refer to same datum.

DISCHARGE MEASUREMENTS. Made from cable 400 feet below gage, or by wading.

CHANNEL AND CONTROL. Bed composed of rock and gravel; not likely to shift. 

Channel straight above and below station for 1,000 feet. Left bank high, rocky, 

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

composed of clay and gravel, ,and subject to overflow during extreme stages. 

Position of control not known, but current-meter measurements indicate that it 

is practically permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 17.0 feet at 3 p. m. 

September 4 (discharge, 15,300 second-feet; determined from extension of rating 

curve and possibly subject to slight error); minimum stage, 0.34 foot July 20 

and 21 and August 20 (discharge 18 second-feet). 

1916-1917: Maximum and minimum stages occurred in 1917.

ICE. None reported during year.

DIVERSIONS. No large irrigation works have been completed in drainage basin above 

station, but tracts ranging in size from 5 to 1,500 acres adjacent to the main river 

and tributaries are irrigated by diversion. A large part of the irrigated area is 

in Runnels, Brown, and Mills counties and along Concho and San Saba rivers. 

Several small dams have been constructed in the drainage basin above station. 

Chadwick dam, half a mile above, creates a small pond and serves only to divert 

to a water wheel that has not been operated for some time.

REGULATION. Flow not regulated by dams or reservoirs.

ACCURACY. Stage-discharge relation practically permanent. Rating curve well 

denned between 10 and 13,000 second-feet. Rating curve previously used for 

1915-16 has .been revised on account of high-water measurements secured in 

1918. Gage read to hundredths once daily. Daily discharge ascertained by 

applying daily gage height to rating table. Records good.

Records of daily and monthly discharge for 1915-16 based on revised rating curve, 

are published herewith, and supersede those previously published.

LOCATION. At steel highway bridge one-fourth mile south of Marble Falls, Bumet 

County, 10 miles below mouth of Sandy Creek, 16 miles below mouth of Llano 

River, and 23 miles above mouth of Pedernales River.

DRAINAGE AREA. 32,200 square miles.

RECORDS AVAILABLE. October 1, 1916, to September 30, 1917. Miscellaneous discharge measurements were made in 1902. Records of stage have been obtained 

by the United States Weather Bureau since January 1, 1908.

GAGE. Weight-and-tape gage of the Mott type/ fastened to steel post on upstream side 

of bridge, 60 feet south of middle bridge pier; read by M. M. Berry.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Bed composed of solid rock. Banks, rock, gravel, and 

clay, wooded, high, and not subject to overflow. Rapids just below gage serve 

as permanent control for low and medium.stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 8.0 feet at 7.30 

a. m. October 20and September 5 (discharge, 17,100second-feet); minimum stage, 

zero several times during July and August (discharge, 14 second-feet).

. and tributaries are irrigated by diversion. A large part of the irrigated land in 

the basin is along Concho, San Saba, and Llano rivers. The Second Report of 

the Board of Water Engineers for the State of Texas shows a filing by the Llano 

Milling & Mining Co. for continuous use of 833 second-feet for hydraulic power 

and waterworks, and a filing of an unknown amount (believed to be small) by 

M, H, Reed for waterworks of Marble Falls,
30 SURFACE WATER SUPPLY, 1917, PART VIII.

REGULATION. Flow regulated somewhat by diversions for irrigation and power in 

the basin immediately above station.

ACCURACY. Stage-discharge relation permanent. Rating curve well denned between 

10 and 52,000 second-feet. Gage read to hundredths twice daily, July 1 to September 30; to tenths, once daily, October 1 to June 30. Daily discharge ascertained by applying daily gage height to rating table. Records good.

COOPERATION. Record of gage height October 1 to June 30 furnished by United 

States Weather Bureau.

from September 1,1895, to April 7,1900. Gage used February 15,1898, to December 31,1911, was a vertical gage attached to bathhouse on left bank 150 feet above 

Congress Avenue bridge; during this period high-stage readings were made by 

means of a staff gage painted on first pier from left end of bridge and a chain 

gage attached to bridge. All gages at or near the bridge have been referred to the 

same datum.

DISCHARGE MEASUREMENTS. Made by wading or from upstream side of Montopolis 

highway bridge, 4 miles downstream.

CHANNEL AND. CONTROL. Channel straight for 1,000 feet above and 500 feet below 

statidn. Right bank of medium height, composed of clay and gravel, clean, 

improved by city, and not subject to overflow; left bank resembles right bank 

except that it is high and nearly vertical in places. Bed composed of rock and 

gravel, clean; shifts. Control is a gravel and rock shoal 500 feet below gage; 

changes during high wa^er and also during low water because of the removal of 

sand for municipal use.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 5.20 feet at 6 

a. m. October 21 (discharge, 11,100 second-feet); minimum stage, 0.04 foot at 3 

p. m. August 28 and 10 a. m. August 29 (discharge, 51 second-feet).

1898-1911; 1914-1917: Maximum stage recorded, 33.5 feet April 7, 1900 (discharge, 122,000 second-feet); rm'nirmiTn stage, 0.50 foot December 13-17, 1914 

(discharge, 2 second-feet). 

ICE. None during year.
32 SURFACE WATER SUPPLY, 1917, PART VIII.

DIVERSIONS. The Second Report of the Board of Water Engineers for the State of 

Texas shows that about 36,000 acres of land were declared irrigated by diversions from Colorado River above station. The report also 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; 160 acre-feet per annum for Winchell waterworks; 2,000 acrefeet for waterworks for city of Brown wood; and an unknown amount for Marble 

Falls waterworks, all above station. An annual consumption in millions of 

gallons was reported to Board of Water Engineers, in 1916, by the city of Brownwood of 310, and city of Austin, 946. Much of the area irrigated is in the upper 

basin of the main stream and adjacent to large tributaries.

REGULATION. Flow entirely regulated by operations at the Austin dam, about 3J 

miles upstream. June 18, gates at Austin dam were opened and water released 

for rice irrigation in lower Colorado drainage until July 20, when gates were closed 

to maintain a low stage in reservoir. High water of September 5 and 6 filled the 

reservoir and water started to flow over crest of dam 4.30 p. m. September 6.

ACCURACY. Stage-discharge relation not permanent; numerous discharge measurements necessary to determine changes. Standard rating curve well defined below 

12,000 second-feet. Error in determinations of mean daily discharge due to regulation of flow eliminated by use of a water-stage recorder. Mean daily gage height, to 

half tenths, obtained by inspecting the recorder graph, or, for days of considerable 

fluctuation, by averaging hourly gage heights. Daily discharge ascertained by 

applying mean daily gage height to rating table directly, October 5-30, November 

14-30, December 9 to February 19 and March 22 to September 14; by shifting 

control method, October 1-4, October 31 to November 13, December 1-8, February 20 to March 21, and September 15-30. Records good.

30, 1917.

EVAPORATION NEAR AUSTIN, TEX.

LOCATION. At reservoir on Hill's ranch, about 1,000 feet from ranch house, 5 miles 

south of Austin, Travis County. Elevation, 475 feet above sea level.

RECORDS AVAILABLE. April 1,1916, to September 30,1917.

EQUIPMENT. Two evaporation pans, one floating on surface of reservoir and the other 

on land about 30 feet from reservoir; auxiliary equipment consists of hook gage, 

rain gage, anemometer, maximum and minimum thermometers, and psychrometer.

ACCURACY. Moss and weed growth in reservoir may at times affect results. Record 

from land pan more accurate than that from floating pan. Observations made 

daily at 8 a. m. Observer's work good.

COLOEADO KTVEK BASIN. 35

COLORADO RIVER AT COLUMBUS, TEX.

LOCATION. At county highway bridge half a block from county jail, 400 feet below 

the Galveston, Harrisburg & San Antonio Kailway bridge, in eastern edge of 

Columbus, Colorado County.

DRAINAGE AREA. 37,000 square miles (revised).

KECORDS AVAILABLE. January 1, 1903, to December 31, 1911; May 22, 1916, to 

September 30, 1917; occasional discharge measurements beginning August 2, 

1902. Records of stage have been obtained by the United States Weather 

Bureau since January 1, 1903.

GAGE. Chain gage attached to downstream bridge railing; read by A. S. Lowrey. 

From August 2, 1902, to December 16,1907, gage heights were obtained by measuring with, a tagged chain and lead weight from point on top of bridge pier to 

water surface. Mott tape and weight gage on downstream handrail of bridge, 

property of the United States Weather Bureau was read from December 17, 1907, 

to February 9, 1917, when chain gage was installed. Mott gage and chain gage 

were referred to same datum.

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

CHANNEL AND CONTROL. Channel straight above and below station for 400 feet. 

Right bank composed of firm earth; high and not subject to overflow; left bank 

of medium height; overflow likely. Bed of stream clean and sandy; shifts during 

high stages. A sand and gravel section about 350 feet below gage serves as lowwater control, but the stage-discharge relation during medium and high stages 

may be controlled by a bend in river below bridge.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 12.14 feet at 

7 a. m. May 7 (discharge, 4,520 second-feet); minimum stage, 5.41 feet from 9 

to 10.30 a. m. August 28 (discharge, 101 second-feet).

1902-1911; 1916-1917: Maximum stage recorded, 35.8 feet April 27, 1908 

(discharge, 43,100 second-feet); minimum stage, 4.2 feet September 9 and 10, 

1910 (discharge, 10 second-feet).

ICE. None reported during year.

DIVERSIONS. Considerable water is diverted for irrigation in the drainage basin 

above Austin, but between Austin and Columbus little water is pumped or 

diverted by gravity. The station is above the irrigated rice belt, which comprises several thousand acres. Filings have been made with the Board of Water 

Engineers for the State of Texas for continuous use of water for Smithville, Bastrop, and La Grange waterworks, all above station. Smithville reported to the 

Board of Water Engineers a consumption of 193,000,000 gallons during 1916.

REGULATION. Flow at Columbus during ordinary stages controlled by storage at 

Lake Austin.

ACCURACY. Stage-discharge relation not permanent. Rating curve well defined 

below 45,000 second-feet. Gage read to hundredths twice a day. Mean of two 

readings may not be a true index of daily discharge because of regulation above 

station. Daily discharge ascertained by applying mean daily gage height to 

rating table directly, October 23 to December 5, February 4 to March 25, and 

April 13 to September 30; by shifting-control method October 1-22, December 6 

to February 3, and March 26 to April 12. Records good.

COOPERATION. Morning gage readings furnished by United States Weather Bureau.

COLORADO RIVER BASIN. 37

DISCHARGE MEASUREMENTS. Made from highway bridge..

CHANNEL AND coNTROL.-rChannel straight above and below station for a few hundred feet. Bed of stream composed of sand and clay. Both banks medium in 

height, composed of clay, and subject to overflow during extreme stages. Discharge measurements show control to be fairly permanent but at times subject 

to shift.

EXTREMES OP DISCHARGE. 1916-1917: Maximum stage recorded during periods of 

record, 3.27 feet at 3.30 p. m. July 25, 1916 (discharge, 1,680 second-feet); minimum stage, 0.90 foot at 7 a, m. August 1, 1917 (discharge, 62 second-feet).

ICE. None reported.

DIVERSIONS. Considerable water is diverted above station for irrigation of rice. 

Station is in area of rice irrigation. The Second Report of the Board of Water 

Engineers for the State of Texas shows that 51,126 acres were declared irrigated 

in Colorado and Wharton counties by means of 102,252 acre-feet of water. A large 

part of this area is irrigated by means of water pumped from Colorado River above 

the station.

REGULATION. Flow is regulated by diversions for rice irrigation and storage in 

Austin Lake.

ACCURACY. Stage-discharge relation subject to change. Rating Curves fairly well 

denned. Gage read to hundredths twice daily. Mean of two readings may not 

be a true index of daily discharge because of regulation above station. Daily 

discharge ascertained by applying mean daily gage height to rating table directly, 

July 12-30, 1916, and July 3 to August 18, 1917; by shifting-control method, 

July 31 to August 10, 1916; and from parallel curve August 11 to 31, 1916. Discharge interpolated August 14, 1916, and July 18, 1917. Records good.

NORTH CONCHO RIVER AT SAN ANOELO, TEX.

LOCATION. At county concrete viaduct in San Angelo, Tom Green County, 1 mile 

above confluence of North Concho and South Concho rivers.

DRAINAGE AREA. 7,530 square miles.

RECORDS AVAILABLE. October 27, 1915, to September 30, 1917.

GAGE. Vertical staff attached to web of third pier of viaduct from left bank; auxiliary 

staff on left bank 75 feet upstream from bridge referred to same datum; read during 

stages 0 to 6.8 feet; read by T. R. Lyle and L. E. Gage.

DISCHARGE MEASUREMENTS. Made by wading 400 feet below viaduct.

CHANNEL AND CONTROL. Bed composed of solid rock which is to some extent covered 

in high-water channel with grass and moss; permanent. Channel straight for 500 

above and 400 feet below gage. Both banks are sloping, clean, composed of rock 

and clay, and not subject to overflow except during high floods. About 20 feet 

below gage and at downstream side of viaduct is a concrete dam about 4J feet 

high, which before the viaduct was constructed, served as part of a low-water 

crossing. This dam forms an artificial control and insures a permanent stagedischarge relation.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 4.90 feet at 8.30 

a. m. April 18 (discharge, 1,900 second-feet; determined from extension of rating 

curve and possibly subject to considerable error). No flow during several periods 

throughout year. 

1916-1917: Maximum and minimum stages recorded in 1917.

ICE. None reported during year.

DIVERSIONS. According to Second Report of the Board of Water Engineers for the 

State of Texas some water is diverted; amount diverted above station not known.

REGULATION. Flow not regulated by water-power plants or reservoirs.

ACCURACY. Stage-discharge relation permanent. Rating curve well denned below 

but possibly subject to error above 200 second feet. Gage read to hundredths 

daily; oftener during high water. Daily discharge ascertained by applying mean 

daily gage height to rating table. Records good.

40 SURFACE WATER SUPPLY, 1917, PART VIII.

CONCHO RIVER HEAR SAN AHOELO, TEX.

LOCATION. Half a mile below confluence of North Concho and South Conqho rivers, 

If miles southeast of San Angelo, Tom Green County.

DRAINAGE AREA. 10,800 square miles.

RECORDS AVAILABLE. September 17, 1915, to September 30, 1917.

GAGE. Stevens water-stage recorder installed August 9, 1917, on right bank, 1,500 

feet below an old ford. B. H. Cummins, observer. Prior to August 9, 1917, a 

vertical staff gage in several sections attached to trees on left bank opposite waterstage recorder was read by Mrs. B. H. Cummins. Water-stage recorder and vertical staff gage referred to same datum.

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

CHANNEL AND CONTROL. Bed composed of solid rock and gravel. Channel straight 

for 1,000 feet above and below station. Right bank high, rocky, wooded, and 

not subject to overflow; left bank of medium height, composed of clay and 

gravel, covered with scattering trees, and subject to overflow at high stages. 

Rapids just below gage serve as control for medium and low stages; do not shift. 

Position of control for high stages not known. Stage-discharge relation affected 

by moss at low stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 13.7 feet at 9 

a. m. April 18 (discharge not determined); minimum stage, 0.44 foot from 1 to 3 

p. m. August 11 (discharge, 1.0 second-foot).

1915-1917: Maximum and minimum stages recorded in 1917

ICE. None reported during year.

DIVERSIONS Considerable water is diverted above station, and pumping plants are 

immediately below. Second Report of the Board of Water Engineers for the 

State of Texas shows that a total of 22,000 acre-feet per annum is taken from the 

stream for beneficial use. About a mile above mouth of South Concho River a 

storage dam has been constructed by the San Angelo Light & Power Co. for 

waterworks, but as the capacity of the reservoir is small and the height of the 

dam constant, a large part of the natural flow of the stream that enters the reservoir will join the water of the North Concho at confluence of the two streams.

REGULATION. Storage at the dam of the San Angelo Light & Power Co. has slight 

effect on flow at station; no regulation by storage on North Concho River.

ACCURACY. Stage-discharge relation practically permanent. Rating curve well 

defined below 400 second-feet. Gage read to hundredths once daily prior to 

August 9, 1917; after that date water-stage recorder in operation; one reading 

daily may not be a true index of the mean daily discharge because of regulation 

and rapid fluctuation during floods. Daily discharge ascertained by applying 

daily gage height to rating table. Mean daily gage height determined from 

recorder chart by use of planimeter. Records good for medium and low stages, 

and poor for high stages; determination of discharge above 500 second-feet may 

be considerably in error.

42 SUEFACE WATER SUPPLY, 1911?, PART VIII.

CONCHO RIVER NEAR PAINT BOCK, TEX.

LOCATION. At Concho, San Saba & Llano Valley Railroad bridge a quarter of a mile 

below mouth of Kickapoo Creek, 2 miles northwest of Paint Rock, Concho County.

DRAINAGE AREA. 11,800 square miles.

RECORDS AVAILABLE. September 20,1915, to September 30,1917.

GAGE. Vertical staff attached to downstream end of middle railroad bridge pier; 

read by Bob Word.

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

CHANNEL AND CONTROL. Bed composed of solid rock, smooth, clean, free from 

vegetation, and permanent. Channel straight for 500 feet above and below gage. 

Right bank 30 feet high, solid rock, clean, and not subject to overflow; left bank 

of medium height, sloping, wooded, and subject to overflow during high water. 

Permanent control during low and medium stages at a shoal in solid rock 400 feet

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 8.5 feet at 5.20 

p. m. April 18 (discharge, 7,150 second-feet); no flow June 21-24, and July 6 to 

August 18.

1915-1917: Maximum stage recorded, 8.6 feet 11.30 a. m. September 24, 1915 

(discharge, 7,300 second-feet); no flow July 4 to September 1, 1916, June 21-24, 

1917, and July 6 to August 18, 1917.

ICE. None reported during year.

DIVERSIONS. Station is above a large part of the irrigable area in the vicinity of 

Paint Rock, but considerable water is diverted from the stream in that part of 

the basin above San Angelo; quantity of water diverted between San Angelo and 

this station not known, but during low stages the flow is affected thereby.

REGULATION. Ten storage dams of small capacity are located between this station 

and San Angelo. An abandoned dam, 12 feet high, known as "Four-Mile dam" 

is 4 miles below San Angelo, and a small dam, 8 feet in height, has been constructed for storage on Sims ranch just above the station. An 11-foot concrete 

dam was constructed during the summer for storage at a point 12 miles above 

gage, but the high water of September destroyed it. None of the dams appreciably affect the flow by storing water except during extremely low stages.

ACCURACY. Stage-discharge relation permanent. Rating curve fairly well denned 

below 6,500 second-feet; determination above 6,500 second-feet possibly subject 

to slight error. Rating curve previously used for 1915-16 has been revised on 

account of high water measurements secured in 1918. Gage read to hundredths 

once daily; oftener during high water. Daily discharge 1915-1917 ascertained 

by applying mean daily gage height to rating table. Records good.

Records of daily and monthly discharge for 1915-16, based on revised rating curve, 

are published herewith, and supersede those previously published.

PECAN BAYOU AT BROWNWOOD, TEX.

LOCATION. Near city pumping plant of Brownwood, 600 feet above lower city dam, 

at City Park, 1 mile north of Brownwood, Brown County, 2 miles above mouth of 

Adams Branch, 30 miles above confluence with Colorado River.

DRAINAGE AREA. 1,560 square miles.

RECORDS AVAILABLE. May 24, to September 30,1917.

GAGE. Vertical staff attached to two trees on right bank about 200 feet below pumping plant; read by C. N. Davis. From May 24 to June 3 readings were taken 

from an inclined and vertical staff gage located at right end of lower dam. This 

gage was destroyed June 4 and present gage installed June 8. Present gage referred 

to datum 1.04 feet lower than original one to avoid negative readings.

DISCHARGE MEASUREMENTS. Conditions will not allow measurements at low stages, 

but high and medium stage measurements can be made from upstream side of 

highway bridge located 800 feet below lower city dam.

CHANNEL AND CONTROL. Bed composed of mud and clay, free from vegetation. 

Channel straight above and below station. Banks wooded; subject to overflow 

during extreme high stages. When stream is nearly bank full, water is likely to 

flow through a slough that leaves the river a short distance above the gage and connects with Adams Branch. One channel at all stages when flow is confined by 

banks of main stream. City dam, 600 feet below gage, serves as a control when 

flow is confined within banks; dam has opening of 140 feet; crest regular. Position 

of control when banks are submerged not known.
COLORADO RIVER BASIN. 45

EXTREMES OF DISCHARGE. Maximum stage recorded during period of record, 

4.40 feet at 6 p. m. September 3 "(discharge, 3,340 second-feet: determined by 

formula using the dam as a weir; possibly subject to considerable error); no flow 

June 13 to August 19, August 26 to September 2, and September 16-30.

ICE. None reported.

DIVERSIONS. The Second Report of the Board of Water Engineers for the State of 

Texas shows that 590 acres were declared irrigated by a beneficial use of 1,179 

acre-feet of water diverted from Pecan Bayou above the station. This report also 

lists a filing by the city of Brownwood for a storage of 2,000 acre-feet for waterworks. The city of Brownwood reported a consumption of 310 million gallons 

during 1916, pumped from stream just above station. Two pumping plants are 

operated below the control dam near Brownwood, but the amounts pumped are 

not known.

REGULATION. Flow at station regulated during normal flow by storage reservoir and 

pumping plants above. Two miles above the station the city of Brownwood has 

constructed a dam to impound water for municipal use. Water is released from 

this reservoir when the supply is short in pond at the gage from which the city 

supply is pumped. Backwater from the lower dam extends to the upper dam.

ACCURACY. Stage-discharge relation practically permanent. Rating curve based 

on discharge computed by formula, using the dam as a weir, and one low-water 

discharge measurement; possibly subject to error. Length of dam makes station 

sensitive. Gage read to hundredths twice daily; of tener during high stages. Daily 

discharge ascertained by applying mean daily gage heights to rating table. Records poor.

SAN SABA RIVER AT MENARD, TEX.

LOCATION. At steel highway bridge in Menard, Menard County, about 80 miles 

above mouth of stream.

DEAINAGE AREA. 1,140 square miles.

RECORDS AVAILABLE. September 14, 1915, to September 30, 1917.

GAGE. Chain gage attached to floor on downstream side of highway bridge; read 

by Henry Patton.

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

CHANNEL AND CONTROL. Channel straight 800 feet above and 100 feet below station; 

water flows through a series of shoals and ponds, channel above gage somewhat 

obstructed by reeds and grass, but below the gage the flow is only slightly obstructed at times. Right bank composed of gravel and clay, wooded, sloping, 

high, and not subject to overflow; left bank similar in material, wooded, low, 

and subject to overflow during high stages. A sand and gravel ford just below 

gage forms a practically permanent control during low and medium stages but 

shifts during high stages.

EXTREMES or DISCHARGE. Maximum stage recorded during year, 3.90 feet at 8.20 

a. m. June 3 (discharge, 425 second-feet; determined from extension of rating 

curve and possibly subject to considerable error); minimum stage recorded, 

1. 61 feet at 6 p. m. July 30 (discharge, 0.6 second-foot, determined from extension 

of rating curve; possibly subject to considerable error).

1915-1917: Maximum stage recorded, 13.6 feet at 2.30 a. m. September 16, 

1915 (discharge not determined); minimum stage July 30, 1917.

ICE. None reported during year.

DIVERSIONS. Considerable land is irrigated with water diverted or pumped above 

station. Noyes canal, on right side of river, which serves a considerable area 

of land carries water that is diverted a short distance above gage. Several pumping plants are above and below gage. The Second Report of the Board of 

Water Engineers for the State of Texas shows that 5,807 acres are declared 

irrigated with 11,614 acre-feet of water per annum in Schleicher and Menard 

counties. More than half of this area is above the station.

REGULATION. Flow unregulated by storage or water-power plants but is largely 

controlled by diversion to Noyes canal.

ACCURACY. Stage-discharge relation practically permanent during low and medium 

stages, but changes during high water; changed somewhat during period October 

6-12. Rating curve well denned between 1 and 90 second-feet. Determinations 

of discharge above 100 second-feet may be subject to considerable error. Gage 

read to hundredths twice daily; oftener during high water. Daily discharge 

ascertained by applying mean daily gage heights to rating tables directly 

October 1-5, October 13 to April 20, and June 3 to September 30; by shiftingcontrol method October 6 to 12 and April 21 to June 2. Records good except 

for extreme stages for which they may be considerably in error.

SAN SABA RIVER NEAR SAN SABA, TEX.

LOCATION. 200 feet above Beveridge highway bridge, 1 mile below mouth of China 

Creek, 2 miles northwest of San Saba, San Saba County, 3 miles below mouth of 

Richland Creek, 4 miles above mouth of Simpson Creek.

DRAINAGE AREA. 3,000 square miles.

RECORDS AVAILABLE. December 30, 1904, to December 31, 1906; September 11, 

1915, to September 30, 1917. Miscellaneous discharge measurements previous 

to 1904.

GAGE. Vertical and inclined staff, on right bank; read by G. M. Pool. From December 30, 1904, to December 31, 1906, gage heights were obtained by measuring 

with a tape from a reference point on the bridge to the water surface; Relation 

between datum used 1904-1906 and that of present gage is not known.

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

CHANNEL AND CONTROL. Channel straight above and below station for 100 feet. 

Bed composed of rock and gravel; shifts. Left bank composed of gravel and 

clay, wooded, high, and not subject to overflow; right bank consists of clay and 

gravel, wooded, sloping, medium in height, and subject to overflow during high 

water. A shoal at a ford about 75 feet below gage serves as control during medium 

and low stages; control is free from vegetation and is fairly permanent during low 

and medium stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 21.5 feet 1.30 

p. m. June 3 (discharge not determined); minimum stage, 0.84 foot during July 

13 (discharge, 6.8 second-feet).

1904-1906; 1915-1917: Maximum stage recorded, 31.7 feet August 7, 1906 (discharge not determined); minimum flow July 13, 1917.

ICE. None reported during year.

DIVERSIONS. Considerable water is diverted or pumped from the stream and tributaries above station. There are also diversions below the station, but none in the 

vicinity of the station. The Second Report of the Board of Water Engineers for 

the State of Texas shows that about 11,000 acres of land were declared 

irrigated, and that about 23,000 acre-feet of water is used each year from 

San Saba River. A large part of this amount is diverted above the station. 

Flood water from Brady Creek at Brady is stored for municipal uses; capacity of 

reservoir not known but probably small. City of Menard uses small amount for 

waterworks.

REGULATION. Flow not regulated by dams or reservoirs.
COLOKADO KIVEK BASIN. 49

ACCURACY. Stage-discharge relation fairly permanent during low and medium 

stages. Rating curve fairly well denned between 15 and 1,200 second-feet; determinations above 1,200 second-feet possibly subject to considerable error. 

Rating curve previously used for 1915 and 1916 has been revised in accordance 

with measurements at higher stages subsequently made. Gage read to hundredth^ 

twice daily; oftener during high water. Daily discharge ascertained by applying mean daily gage height to rating table as indicated in footnote to table of 

daily discharge. Records excellent except for periods of high water.

Records of daily and monthly discharge for 1915 and 1916, based on revised rating 

curve, are published herewith and supersede those previously published.

Sept. 30, 1917.

COLORADO RIVER BASIN. 51

NORTH LLANO RIVER NEAR JTTNCTION, TEX.

LOCATION. About 500 feet above remains of old Wilson dam, 1 mile below mouth of 

Bear Creek, 2J miles above North Llano highway bridge, 3 miles northwest of 

Junction, Kimble County, 4 miles above confluence of North Llano and South 

Llano rivers.

DRAINAGE AREA. 803 square miles.

RECORDS AVAILABLE. September 14, 1915, to September 30, 1917.

GAGE. Overhanging chain gage on left bank; read by W. T. Hardesty.

DISCHARGE MEASUREMENTS. Made by wading or from highway bridge 2J miles 

below station.

bank high, clean, and not subject to overflow; right bank low, wooded, and subject to overflow during high stages. One channel at all stages; current sluggish 

at gage during low and medium stages. A solid rock ledge of approximately 

2 feet vertical fall at site of old dam serves as a permanent control for medium 

and low stages; control clean and free from vegetation.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.96 feet at 7.30 

a. m. May 21 (discharge, 700 second-feet, determined from extension of rating 

curve and possibly subject to some error); nm'TvimnTn stage, no flow July 16 to 

September 2 and September 30.

1915-1917: Maximum stage recorded, 18.0 feet during nightof September 15,1915

COLORADO RIVER BASIN.

LLANO RIVER NEAR JUNCTION. TEX.

LOCATION. 100 feet north of Kerrville-Junction road, a quarter of a mile northeast 

of Oliver's ranch house, 3 miles below confluence of North Llano and South 

Llano rivers, 3J miles east of Junction, Kimble County, 4 miles above creek 

entering river from south.

DRAINAGE AREA. 1,700 square miles.

RECORDS AVAILABLE. September 13, 1915, to September 30, 1917.

GAGE. Vertical staff, reading from 0 to 7.5 feet, attached to tree on right bank, and 

inclined staff, reading from 7.6 to 19.5 feet, a few feet upstream from vertical 

staff; read by Sadie Oliver.

DISCHARGE MEASUREMENTS. Made by wading at Mason road crossing a quarter of 

a mile above gage, or from cable 400 feet above gage.

CHANNEL AND CONTROL. Bed composed of solid rock, 1 clean, and permanent. 

Channel straight for 700 feet above and 350 feet below the gage. Left bank of 

medium height, slightly wooded, and subject to overflow during high water; 

right bank clean, high, and not subject to overflow. One channel at all stages 

except during extreme floods, when a small part of the flow may follow a slough 

that leaves the river a short distance above the gage, passes to the south of Oliver's 

ranch house, and enters the main stream below the gage. Such conditions do 

not occur, however, at intervals more frequent than 10 to 15 years and will not 

greatly affect records. Rock ledge about 75 feet below gage, forming a fall of 

about 3 feet, serves as permanent control for low and medium stages.

EXTREMES OF DISCHARGE.Maximum stage recorded during year, 1.88 feet during 

night of May 11 (discharge, 192 second-feet); minimum stage 1.34 feet during 

August 24 and 25 (discharge, 17 second-feet).

1915-1917: Maximum stage recorded, 26.3 feet at 3 a. m. September 16, 1915 

(discharge not determined); minimum stage August 24 and 25, 1917.

TCE. None reported during year.

DIVERSIONS. The Second Report of the Board of Water Engineers for the State of 

Texas shows that 4,741 acres of land have been declared irrigated requiring 9,482 

acre-feet of water annually from Llano River and tributaries above the station 

* on the assumption that the duty of water is 2 acre-feet per acre. Available data 

show that a large part of this land is in the vicinity of Junction, near the confluence 

of North Llano and South Llano rivers. A filing of 500 second-feet for continuous 

use in connection with hydraulic power for the Junction Gin & Water Co. is also 

listed in the same report.

REGULATION. No apparent regulation of the flow at this point. '.:--

ACCURACY. Stage-discharge relation practically permanent. Rating curve well defined between 20 and 300 second-feet. Gage read to hundredths once daily; 

during high water oftener. Daily discharge ascertained by applying mean daily 

gage heights to rating table. Records excellent for medium and low stages; 

determination of discharge above 400 second-feet may be subject to error.

COLOBADO BIVEB BASIN. 55

BARTON CREEK AT AUSTIN, TEX.

LOCATION. 500 feet below Barton Springs, 1,100 feet above Bee Cave highway 

bridge, half a mile above confluence with Colorado River, half a mile southwest 

of Austin, Travis County.

DRAINAGE AREA. Indeterminate. Normal flow at station comes from Barton 

Springs; drainage area of stream not applicable.

RECORDS AVAILABLE. April 25, to September 30, 1917. Miscellaneous discharge 

measurements have been made from 1894 to 1906, and during 1916 and 1917.

GAGE. Vertical staff, two sections, reading from 0 to 10.1 feet and 10. 2 to 20.3 feet, 

attached to large tree on left bank; read by M. L. Farquhar. April 25 to May 

23, gage readings from a vertical staff gage 300 feet downstream. Relation between datums not known.

DISCHARGE MEASUREMENTS. Made by wading about 800 feet below gage.

CHANNEL AND CONTROL. Bed composed of rock, gravel, and sand. Banks high, 

wooded, and not subject to overflow. One channel at all stages. Shoal just below 

gage serves as a control during ordinary flow, but weed growth in channel affects 

stage-discharge relation. Flood stages in Colorado River cause backwater at the 

station.

EXTREMES OF DISCHARGE. Maximum flow during period of record, June 1 to 4 

(discharge, 19 second-feet, or 11,300,000 gallons per day); minimum flow, May 

20 and 21, and August 2-20 (discharge, 13 second-feet, or 8,400,000 gallons per day). 

1894-1906; 1916-1917: Maximum flow recorded August 31,1900, and June, 1903 

(discharge, 69 second-feet, or 44,600,000 gallons per day); minimum flow, May 

20 and 21, 1917, and August 2-20, 1917.

ICE. None reported.

DIVERSIONS. So far as known no diversions above or below station.

REGULATION. Flow not affected by water power plants or controlling works. Discharge of Barton Springs regulates flow during ordinary conditions. Flow is 

perennial at station, but from a point 3 miles northeast of Oak Hill to Barton 

Springs, is erratic, occurring only during heavy precipitation.

ACCURACY. Stage-discharge relation affected by growth of weeds in channel. Rating 

curve poorly defined; discharge determined by interpolation between discharge 

measurements. Gage read to hundredths twice daily. Constant flow does not 

require additional readings. Frequent discharge measurements increase accuracy of records. Records good.

GTTADALTJPE RIVER BASIN.

GTTADALTTPE RIVER AT NEW BRATJNFELS, TEX.

LOCATION. At highway bridge on San Antonio-Austin post, road 700 feet below 

International & Great Northern Railway bridge, 1 mile below mouth of Comal 

River, 1 mile northeast of center of New Braunfels, Comal County.

DRAINAGE AREA. 1,760 square miles.

RECORDS AVAILABLE. March 13, 1898, to December 30, 1899; January 27, 1915, 

to September 30, 1917.

GAGE. Stevens water-stage recorder referred to staff gage in well, attached to downstream side of middle pier of highway bridge. A vertical staff gage in three sections attached to trees on left bank 200 feet below highway bridge and one section 

on east side of left pier of highway bridge was read from January 27,1915, to September 28, 1917, when recorder was installed. Gage used from March 13, 1898, 

to December 30, 1899, was an inclined staff gage near present highway bridge; 

relation between datum of earlier gage and that of present gage not known. During normal flow levels show 0.08 foot fall between intake of recorder and vertical 

staff gage location. Vertical staff gage in well of recorder set to read same as vertical staff downstream.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

CHANNEL AND CONTROL. Bed composed of solid rock with pockets of coarse gravel; 

banks gravel, clay, and rock, slightly wooded, high, and not subject to overflow. 

Rock and gravel shoal just below gage serves as control; permanent.
GUADALUPE RIVER BASIN. 57

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.60 feet at 

6 a. m. September 7 (discharge, 2,370 second-feet); minimum stage, 1.50 feet 

August 26 to September 2 (discharge, 305 second-feet).

1898-1899 and 1915-1917: Maximum stage recorded, 27.2 feet at 9.30 p. m. September 17, 1915, determined by leveling from flood marks (discharge not determined); minimum stage recorded, August 26 to September 2, 1917.

ICE. None reported during year.

DIVERSIONS. Some water diverted for irrigation above station in Kerr and Coma! 

counties, and for water power, waterworks, and other municipal uses in Kerr, 

Kendall, and Comal counties; amount not known.

REGULATION. Flow at this point slightly regulated by operation of power plants.

ACCURACY. Stage-discharge relation practically permanent. Rating curve well 

denned below 7,000 second-feet. Gage read to hundredths twice daily prior to 

September 28. Mean daily gage height obtained from two readings may not be 

a true index of mean daily flow because of fluctuation caused by operations of 

power plant. Gage heights from recorder chart determined by planimeter. Daily 

discharge ascertained by applying mean daily gage height to rating table. Records good.

GTTADALUPE RIVER NEAR GONZALES, TEX.

LOCATION. Just below 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, 1915, to September 30, 1917. The United States 

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

Water Power Co. since September 1, 1904.

GAGE. Vertical staff in three sections on right bank just below bridge; read by 

Albert Garcia. Relation between this gage and that of United States Weather 

Bureau not known.

DISCHARGE MEASUREMENTS. Made from cable one-fourth mile below gage, or by 

wading below cable.

CHANNEL AND CONTROL. Bed composed of gravel and sand; channel below station 

is straight for 500 feet, but above is broken by an island and is straight for not 

more than 50 feet. Banks composed of gravel and clay; medium height; wooded 

along water's edge on the right and for some distance back on the left; subject to 

overflow onjy during extremely high stages. Position of control not known.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 15.14 feet from 

8 to 9.30 a. m. May 8 (discharge, 7,800 second-feet); minimum stage, 0.62 foot at 

6.30 p. m. August 25 (discharge, 350 second-feet).

1915-1917: Maximum stage recorded, 23.25 feet at 7 a. m. May 25, 1916 (discharge, 22,800 second-feet; determined from extension of rating curve and possibly subject to error); minimum stage, August 25, 1917.

ICE. None reported during year.

DIVERSIONS. Some water diverted for irrigation above this point by gravity or pumping, but the amount is small in comparison with the total run-off. As rainfall is 

nearly sufficient for general farming, irrigation is intermittent and it is extremely 

difficult to estimate the amount of water used.

REGULATION. Flow at this point regulated somewhat by operation of water-power 

plants in the drainage above. Power house of Gonzales Water Power Co. is 

located one mile above station.

ACCURACY. Stage-discharge relation practically permanent during the year. Rating 

curve fairly well denned below 9,000 second-feet. Gage read to hundredth^ 

twice daily. Mean daily gage height based on two readings may not be true 

index of mean daily discharge because of fluctuation caused by power operations. 

Daily discharge ascertained by applying mean daily gage height to rating table. 

Records fair.

60 SURFACE WATER SUPPLY, 1917, PART VIII.

GUADALTTPE RIVER BELOW CUERO, TEX.

LOCATION. Three-fourths mile upstream from Heard's bridge on Arneckville road, 

1 mile south of Dietze farmhouse, 2 miles below Clinton bridge, 2J miles southeast of Cuero, Dewitt County, 4 miles below Schleicher bridge, 8 miles below 

dam used for power development.

DRAINAGE AREA. 5,020 square miles.

RECORDS AVAILABLE. August 6, 1916, to September 30, 1917. From December 26, 

1902, to December 31, 1906, and August 19, 1915, to August 6, 1916, a station was 

maintained at Schleicher bridge, 4 miles above this point. Discharge at two 

sites practically the same.

GAGE. Stevens water-stage recorder on left bank.

DISCHARGE MEASUREMENTS. Made from cable 40 feet upstream from gage or by 

wading below low-stage control.

CHANNEL AND CONTROL. Channel straight above and below station for 1,000 feet. 

Bed composed of gravel and small rock; clean and not subject to shift. Left 

bank composed of sand and dirt, covered with brush and open timber and is 20 

feet high, but at stage above a gage height of 20 feet is overflowed, the water submerging an area extending one-fourth mile back from the river; right bank composed of sand and dirt, covered with brush and trees on sloping sides and 

cultivated land on top; high and not subject to overflow. Rock and gravel rapids 

250 feet below gage serves as a permanent control during low and medium stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, from water-stage 

recorder, 9.58 feet at 3 p. m. May 9 (discharge, 6,930 second-feet); minimum 

stage, from water-stage recorder, about 0.60 foot at 9 a. m. September 27 (discharge, 80 second-feet); exact stage not determined because of sand in float well; 

discharge determined from extension of rating curve and possibly slightly in error. 

1916-1917 Maximum and minimum stages recorded in 1917.

ICE. None reported during year.

DIVERSIONS. Diversion of small quantities of water for irrigation in upper part of 

Guadalupe River basin does not greatly influence flow at station. The second 

report of the Board of Water Engineers for the State of Texas shows filings for 

730 acre-feet per annum for the city of Cuero, 4,277 second-feet for continuous 

use for municipal and manufacturing plants, 2,145 acre-feet per annum for New 

Braunfels, Seguin, and Gonzales, and 2,900 acre-feet storage per annum in the 

drainage basin above station.

REGULATION. Flow regulated by operation of water-power plants upstream, chiefly 

by a plant about 8 miles above.

ACCURACY. Stage-discharge relation practically permanent. Rating curve well 

defined between 200 and 7,500 second-feet. Operation of the water-stage recorder 

unsatisfactory, resulting in breaks in the gage-height record. Daily discharge 

ascertained by applying to rating table mean daily gage height determined by 

use of planimeter. Records good.

SAN MARCOS RIVER AT SAN MARCOS, TEX.

LOCATION. Just below Cape Ginning Co.'s mill, 300 feet southwest of main San 

Marcos-Luling highway, 1 mile southeast of San Marcos, Hayes County, 1J miles 

above mouth of Blanco River, 1J miles below dam of San Marcos Utilities Co., 

and the large springs that furnish a constant supply for the stream.

DRAINAGE . Indeterminate,
62 SURFACE WATER SUPPLY, 1917, PART VIII.

RECORDS AVAILABLE. June 10, 1915, to January 19, 1916; March 13, 1916, to September 30, 1917. Miscellaneous measurements made from 1894 to 1903.

GAGE. Stevens water-stage recorder on left bank, 300 feet below Cape Ginning Co.'s 

mill. Gage used June 10, 1915, to January 19, 1916, was a vertical staff gage 

attached to the sewer trestle of San Marcos Utilities Co., 1,000 feet below AustinSan Antonio highway bridge, 1J miles above present site. No known relation 

between datum of staff gage and that of water-stage recorder.

DISCHARGE MEASUREMENTS. Made by wading.

CHANNEL AND CONTROL. Bed composed of gravel and sand; some vegetation in the 

flowing water. Channel straight for 200 feet above and below the station. Water 

very clear, deep, and with scarcely any sediment except during floods caused by 

local rains. Channel was cleaned and dredged above and below gage June 21-29 

to increase head for Cape Ginning Co.'s mill. Left bank wooded, high, and not 

subject to overflow; right bank wooded, low, and subject to overflow, the water 

spreading back a short distance to a second bank. Position of control not known; 

current-meter measurements indicate that it changes slightly.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, from water-stage 

recorder, 8.05 feet (no backwater from Blanco River) at 1 p. m. May 6 (discharge 

not determined); minimum stage recorded, 0.38 foot at 4.30 p. m. August 22 

(discharge, 20 second-feet; determined from extension of rating curve and possibly in error). 

1915-1917: Maximum and minimum stages recorded in 1917.

ICE. None reported during year.

DIVERSIONS. A concrete dam just above the San Marcos-Luling road bridge makes 

a pond for Roger's resort and serves as a diversion dam for an irrigation plant on 

left bank; diversion intermittent, but when used takes about 95 second-feet 

from river. A water wheel is used to pump the water for irrigation and the water 

that passes through it is returned to the river above Cape Ginning Co.'s dam. 

About 1,000 feet above the station is a dam constructed for the purpose of creating 

a pond from which water was pumped to the south-bank lands. Only pumping 

plant or diversion between station and mouth of Blanco River is about 250 feet 

below gage. Beckman dam, just below mouth of Blanco River, is used to 

impound water for irrigation. During ordinary stages in San Marcos and Blanco 

rivers this dam backs water up San Marcos River a distance of three-quarters of 

a mile, but flood stages in Blanco River produce backwater at the station. The 

Second Report of the Board of Water Engineers of Texas shows a declared acreage 

of 989 acres in Hayes County being irrigated from San Marcos River by means 

of 1,978 acre-feet of water per annum. A large part of this area is above the 

station. The Report of the Board of Water Engineers also shows a filing of 

1,120 acre-feet per annum for waterworks by San Marcos Utilities Co.

REGULATION. Flow at station entirely regulated by dams above, the greatest effect 

being that produced by the power dam of the San Marcos Utilities Co. in the 

upper part of the city of San Marcos, near the springs. This dam backs water 

over the springs that form the source of supply of the river during ordinary stages. 

Water is stored at this point throughout the afternoon and evening and released 

during the morning. Large fluctuations are also caused by operation of water 

wheel at Cape Ginning Co.'s mill.

ACCURACY. Stage-discharge relation changes slightly; rating curve fairly well 

defined from 35 to 200 second-feet. The periods of back-water from Blanco River 

are of short duration only and the constant flow of San Marcos River allows estimates of the discharge to be made without material reduction in accuracy. 

Mean daily gage height determined by use of planimeter. Discharge determined 

by shifting-control method. Records good.

SAN MARCOS RIVER AT OTTINE, TEX.

LOCATION. Above highway bridge one-fourth 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, 1915, to September 30, 1917.

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

above bridge; read by J. H. Kaine. Gage used from June 22 to October 12,1915, 

was a vertical staff under the highway bridge, but gage heights have been reduced 

to datum of present gage by means of a curve of relation.

DISCHARGE MEASUREMENTS. Made by wading at shoal 100 feet below gage or from 

downstream side of highway bridge.

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

great shifting. Both banks high and wooded; not overflowed except by extremely 

high water. Channel straight above and below the station for 150 feet. Low-stage 

control formed by shoal 100 feet below gage; during high stages in Guadalupe 

River backwater changes stage-discharge relation; backwater did not exist from 

this cause during 1917.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 26.5 feet at 1 

p. m., May 7 (discharge, 7,480 second-feet). Minimum stage, 1.06 feet at 7 p. m., 

August 26 and 27 (discharge, 26 second-feet). 

1915-1917: Maximum and minimum stage recorded in 1917.

ICE. None reported during year.

DIVERSIONS. Small amounts of water are diverted by gravity or pumping for irrigation in drainage basin above station, but only a small part of the total run-off is so 

used.

REGULATION. Flow regulated by the operation of a small cotton gin a short distance 

above station. The operation of several small water-power plants in the upper 

drainage basin near San Marcos and Martindale does not materially affect the 

flow at this station.

ACCURACY. Stage-discharge relation practically permanent. Gage read once daily 

to hundredths, October 1 to June 30, and twice daily, July 1 to September 30. 

Owing to regulation of the flow the assumption that one gage reading or the mean 

of two daily readings gives the mean for the day causes errors in the determination. Daily discharge ascertained by applying daily gage height to rating table. 

Records good.

66 SURFACE WATER SUPPLY, 1917, PART 'VIII.

SAN ANTONIO RIVER BASIN. 

SAN ANTONIO RIVER AT SAN ANTONIO, TEX.

LOCATION. At Presa Street Bridge, just below-office of San Antonio Water Supply 

Co., in San Antonio, Bexar County, 3 miles below San Antonio Springs, the source 

of the river.

DRAINAGE AREA. Indeterminate.

RECORDS AVAILABLE. October 23, 1914, to September 30, 1917. Miscellaneous 

discharge measurements were made from 1895 to 1906.

GAGE. Vertical staff in two sections attached to upstream side of second bent of 

bridge from right bank and right abutment of bridge; read by E. L. Wilson and 

E. H. Elder. Gage used from October 23,1914, to February 28, 1916, was a vertical staff gage attached to downstream side of middle pier, Commerce Street 

bridge; relation of the datums of these gages not known.

DISCHARGE MEASUREMENTS. Made from downstream side of Market Street bridge, 

(first bridge above station) or by wading just below gage.

CHANNEL AND CONTROL. Channel straight for a short distance above and below 

station, but the general course is very crooked. Bed composed of gravel, sand, and 

silt. Banks high and clean; not subject to overflow except during extremely 

high stages, at which time the river spreads over a wide area. A rock and gravel 

shoal, and remains of old concrete dam just below the station serve as a control. 

Vegetation collects in channel and on control at times, but stage-discharge relation was not affected thereby during 1917.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 1.80 feet March 

24 and 25, and early morning of May 20 (discharge, 147 second-feet) j minimum 

stage recorded 0.76 foot several days during June, July and September (discharge, 23 second-feet).

1914-1917: Maximum stage recorded, 14.0 feet at 5.30 p. m. October 23, 1914 

(discharge, 4,700 second-feet; determined from extension of rating curve and 

possibly subject to considerable error); minimum stage, during June, July and 

September, 1917.

ICE. None reported during year.

DIVERSIONS. Considerable land is irrigated in San Antonio and vicinity south of the 

city; quantity of water diverted not definitely known.

REGULATION. Flow not regulated by permanent dams or controlling works, but at 

times temporary works constructed in improving the channel have regulated the 

flow. Flow at station is dependent on discharge of San Antonio Springs.

ACCURACY. Stage discharge relation practically permanent. Rating curve well defined below 350 second-feet. Gage read to hundredths twice daily. Gage readings prior to April 8 are doubtful. Daily discharge ascertained by applying mean 

daily gage height to rating table. Records fair October 1 to April 10, and good 

April 11 to September 30.

The normal flow of San Antonio River comes from springs within the city limits, 

but two tributaries from the north furnish considerable run-off at times of heavy precipitation. Changes in stage during low flow are believed to be due to pumping from 

deep wells for the city water supply and the use of artesian water for irrigation in areas 

adjacent to the river for it is thought that the wells draw from the underground reservoir that feeds the river by springs.

below San Pedro Springs, source of creek, 3 miles above confluence with San 

Antonio River.

DRAINAGE ABBA. Indeterminate.

RECORDS AVAILABLE. July 20,1916, to September 30,1917.

GAGE. Vertical staff, attached to wall of building No. 713 Commerce Street, on upstream side of bridge on left bank, read by E. L. Wilson and E. H. Elder.

DISCHARGE MEASUREMENTS. Made by wading below gage.

CHANNEL AND CONTROL. Bed composed of rock, gravel and mud; shifting. Channel 

straight above and below station. Both banks formed by walls of buildings. 

City improvements have confined the stream to a small channel during low and 

medium Stages, but during floods the streets are covered with water for several 

blocks. A shoal subject to shift, about 100 feet below gage, serves as control.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.00 feet at 5.10 

p. m. December 30, and during December 31 (discharge 24 second-feet; determined by extension of rating curve and subject to considerable error); minimum 

stage recorded, 1.36 feet during September 11, 12,.and 13 (discharge 2.2 secondfeet).

1916-1917: Maximum stage recorded, 6.25 feet at 7.40 a. m. September 25,1916 

(discharge not determined); minimum stage recorded during September 11, 12, 

and 13,1917.

ICE. None reported during year.

DIVERSIONS . None.

REGULATION. No dams, reservoirs, or controlling works that permanently regulate 

the flow. Fluctuations were caused during year by improvement work along the 

channel above and below the gage.

ACCURACY. Stage-discharge relation not permanent. Rating curve poorly defined. 

Gage read to hundredths twice daily. Daily discharge for 1916 and 1917 determined by indirect method for shifting control. Records poor.

Entire flow of San Pedro Creek, except during times of heavy precipitation, is 

furnished by San Pedro Springs, and the flow at this station is believed to be that 

which reaches San Antonio River. Martinez and Salsamora creeks carry no water 

except during heavy local rains, and have been known to be dry for several years at a 

time.

NUECES RIVER BASIN. 

HTJECES RIVER NEAR CINCHTA., TEX.

LOCATION. Just below suspension highway bridge near Oswald's ranch, 2 miles qast 

of Cinonia, Zavalla County, 8 miles northeast of Crystal City, 20 miles above 

Winter Garden ranch dam.

DRAINAGE AREA. 2,060 square miles.

RECORDS AVAILABLE. July 5, 1915, to September 30, 1917.

GAGE. Dexter water-stage recorder, on right bank, 250 feet below highway bridge. 

Gage readings were taken by C. C. Oswald from vertical staff gage in several sec1- 

tions, on both banks, just below bridge from July 5, 1915, to September 22,1917, 

when recorder was installed.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge by wading 100 

feet below bridge or by wading on crest of concrete control.

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

Banks high and wooded and not subject to overflow. Channel straight above and 

below station. September 23, 1917, a concrete artificial control was completed 

at the site of water-stage recorder installation; point of zero flow, 0.85 foot. The 

stage-discharge relation has been seriously affected at times prior to installation 

of artificial control by collection of logs, leaves, and brush below gage.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.30 feet at 11 

a. m. May 20 (discharge, 90 second-feet); minimum stage, no flow August 4-18 

and 25-28.

1915-1917: Maximum stage recorded, 20 feet at 6.30 a. m. September 19, 1915 

(discharge not determined); minimum stage, no flow August 4-18 and 25-28,1917.

ICE. None reported during year;

DIVERSIONS. Considerable water diverted above station for irrigation; amount not 

known.

REGULATION. Available data indicate no regulation above station.
NUECES RIVEE BASIN. 71

ACCTJBACY. Stage-discharge relation not permanent previous to September 23; per 

manent after that date. Rating curve well defined below 150 second-feet. Gage 

read to half-tenths twice daily October 1 to September 22; gage heights subject 

to error because of careless observations. Mean daily gage height for period of 

recorder record determined by averaging hourly readings from recorder charts. 

Daily discharge ascertained by applying mean daily gage height to rating table 

as indicated in footnote to table of daily discharge. Records fair.

Backwater from a dam 40 feet high, about 20 miles below station, extends within 2 

miles of station when reservoir is full. A large part of the flow of the river is known 

to seep into the bed just below Uvalde and return to the surface just above the station. 

The condition of the underground waters may have an effect on this return water and 

thus help to equalize the flow.

NTJECES RIVER NEAR COTtTLLA, TEX.

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

DRAINAGE AREA. 5,030 square miles.

RECORDS AVAILABLE. July 1, 1915, to September 30, 1917.

GAGE. Vertical staff attached to trees on right bank just above dam; read by Irvin 

Peoples and William Peoples.

DISCHARGE MEASUREMENTS. Made by wading below dam. No facilities for measurements at medium and high stages except at highway bridge 4 miles below gage.

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

above and below station. Banks wooded, medium in height, and not subject to 

overflow. Long concrete dam just below gage serves as a control; crest of dam 

irregular.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 1.10 feet at 10 

a. m. September 4 (discharge, 1,180 seeond-feet, determined from extension of 

rating curve and possibly subject to considerable error); no flow during a large 

part of the year.

1915-1917: Maximum stage recorded, 6.50 feet August 22, 1916 (discharge, 

23,000 second-feet, determined from extension of rating curve and possibly subject to error). No flow during large part of each year.

ICE. None reported during year.

DIVERSIONS. Large part of ordinary flow above station pumped or diverted for irrigation. The station is in upper end of an irrigated section near Cotulla. Two 

large filings are listed in the Second Report of the Board of Water Engineers for 

the State of Texas, in the name of Winter Garden Irrigation Co. and Nueces 

Valley Irrigation Co., in Zavalla and Dimmit counties; irrigable area under each 

system, 10,000 acres; capacities of diversion works 95 and 66 second-feet, respectively.

REGULATION. Flow at station regulated by storage reservoirs and pumping plants 

above.

ACCURACY. Stage-discharge relation permanent. Rating curve based on low-water 

discharge measurements and discharge computed by formula using the dam as a 

weir; possibly subject to considerable error. Because of the length of the dam 

(600 feet) the station is non-sensitive. Gage read to hundredths once daily. 

Daily discharge ascertained by applying daily gage height to rating table. Reo* 

 ords poor.

74 SURFACE WATER SUPPLY, 1917, PART VHI.

NUECES RIVER NEAR THREE RIVERS, TEX.

LOCATION. At San Antonio, JJvalde & Gulf Railroad bridge 1 mile west of Kittle, 

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 1,1915, to September 30,1917.

GAGE. Vertical staff, attached to center pier of railroad bridge; read by P. H. Jank 

and A. J. Sharpley.

DISCHARGE MEASUREMENTS. Made by wading or from highway bridge half a mile 

below gage.

CHANNEL AND CONTROL. Bed composed of adobe shale; does not change greatly. 

Channel straight above and below station. Banks wooded, high, and not subject 

to overflow. Position of high-water control not known; shoal just below gage 

probably forms low-water control. ^

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 13.05 feet at 6 p.m. 

November 10 (discharge, 2,960 second-feet); no flow April 2-21, May 30 to July 21 

and July 31 to August 29.

1915-1917: Maximum stage recorded, 30 feet August 25, 1916 (discharge, 15,500 

second-feet); no flow during large part of each summer.

ICE . None reported during year.

DIVERSIONS. Considerable land irrigated above station but there appears to be no 

irrigable land immediately above.

REGULATION. Flow regulated somewhat by storage reservoirs and pumping in the 

drainage basin above, but the effect is not so pronounced as at the stations in 

the upper part of the drainage basin. Such water-power plants as exist in the 

area above the station are probably small.

ACCURACY. Stage-discharge relation changes slightly. Rating curve well defined 

below 7,000 second-feet. Gage read to hundredths twice daily; oftener when 

fluctuations of stage are rapid or extreme. Daily discharge ascertained by 

applying mean daily gage height to rating table directly October 1-16, and 

November 9 to September 30; by shifting-control method October 17 to November 8. Records good.

NTTECES RIVER AT CALALLEN, TEX

LOCATION. At old pump house for city of Corpus Christi, 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 breakwater dam.

DRAINAGE AREA. 16,700 square miles.

RECORDS AVAILABLE. August 12,1915, to September 30, 1917.
76 SURFACE WATER SUPPLY, 1917, PART VHI.

GAGE. Vertical staff attached to pipe-line support of old pump house; read by Henry 

Wagner.

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

feet below gage.

CHANNEL AND CONTROL. Bed composed of clay and gravel. Channel straight above 

and below station. Left bank wooded, low, and bordered by levee constructed 

to prevent overflow; right bank wooded, medium in height, and not subject to 

overflow. The breakwater, which is a loose rock fill half a mile below, serves as 

control. May 11 and 12 loose rocks were placed below the breakwater, causing 

change in control.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 3.00 feet at 

4 p. m. October 20 (discharge, 1,930 second-feet); minimum stage, 0.40 foot 

at 4 p. m. July 25 (discharge, 0.6 second-foot).

1915-1917: Maximum stage recorded, 8.38 feet September 5, 1916 (discharge, 

6,190 second-feet); minimum stage July 25, 1917.

ICE. None reported during year.

DIVERSIONS. Considerable water taken from river for irrigation immediately above 

station; water also used for irrigation throughout the drainage basin above. 

The city of Corpus Christi pumps water just below the gage for municipal supply 

and has made a filing with the Board of Water Engineers for the State of. Texas 

for a continuous use of 0.93 second-foot and a storage of 675 acre-feet per annum; 

they reported a consumption of 218 million gallons during 1916. A second "small 

 pump for private use installed between city intake and breakwater is seldom 

operated. The quantities pumped are small and do not greatly affect the natural 

flow during ordinary stages.

REGULATION. No water power plants of consequence above station.

ACCURACY. Stage-discharge relation not permanent because of leakage through and 

repair to the breakwater dam. Low-water discharge measurements made at 

breakwater are poor because of leakage through dam. Eating curve fairly well 

defined. Gage read to hundredths twice daily. Daily discharge ascertained by 

applying mean daily gage height to rating table as indicated in footnote to table 

of daily discharge. Allowance made for rising and falling stages in computing 

discharge. Records poor.

FRIO BIVER AT FOWLERTON, TEX.

LOCATION. At Frio River dam, about half a mile northeast of Fowlerton, LaSalle 

County, 1J miles below diversion for Frio Lake storage reservoir, 8 miles below 

mouth of Jahuey Creek.

DRAINAGE AREA. 4,350 square miles.

RECORDS AVAILABLE. July 1,1915, to September 30,1917.

GAGE. Vertical staff attached to tree on right bank about 30 feet above dam; read by 

Joe McMains.

DISCHARGE MEASUREMENTS. Made by wading below dam or from railroad bridge 

about a mile above.

CHANNEL AND CONTROL. Channel straight for some distance above the station, but 

slightly curved below; banks about 5 feet high and not subject to overflow; right 

bank cultivated; left bank wooded. Concrete dam about 20 feet below gage 

serves as permanent control at all stages. Point of zero flow, gage height 0.05

. ^ foot.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 1.3 feet at 5 p. m. 

September 6 (discharge, 470 second-feet); no flow for extended periods.

1915-1917: Maximum stage recorded, 3.9 feet at 6 a. m. April 19, 1916 (discharge, 4,120 second-feet); no flow during parts of each year.

ICE. None reported during year.

DIVERSIONS. Some water diverted for irrigation above station. A diversion for the 

Frio Lake reservoir is made 1J miles above; other diversions are scattered; amount

drainage basin above the station is watered by wells.

REGULATION. Flow regulated by the diversion into Frio. Lake a short distance above 

gage; extent of regulation above Frio Lake diversion not known but probably 

small.

ACCURACY. Stage-discharge relation practically permanent. Rating curve well 

defined below 4,500 second-feet. Gage read once daily to hundredths; slight error 

may be introduced by the assumption that one reading gives the mean stage for 

the day. Daily discharge ascertained by applying daily gage height to rating 

table. Records fair.

DIVERSIONS. Lake is used for storage; capacity not known.

REGULATION. Flow controlled at intake on Frio River, some distance above; flow of 

Frio River above this diversion probably not regulated.

ACCURACY. Stage-discharge relation practically permanent. Rating curve fairly 

well defined below 5,000 second-feet. Gage read to hundredths once daily; one 

daily gage reading may not be a true index of the mean daily discharge. Daily 

discharge ascertained by applying daily gage height to the rating table. Records 

good.

Frio Lake is a storage reservoir fed by a diversion from Frio River. The diversion 

is made 1J miles above the Frio River dam and the gaging station on the river. The 

water released from the lake is used for irrigation. This station is maintained in conjunction with that on Frio River at Fowlerton to show the total run-off at that point.

RIO OBANDE NEAR SAK MARCIAL, H. HEX.

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

bridge 1 mile-south of San Marcial in Socorro County. No large tributaries enter 

near station.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. January 29, 1895, to September 30, 1917.

GAGE. Inclined staff established January 29, 1895, and destroyed by flood in 1896. 

Wire gage established in its place, at same datum, was soon abandoned and 

gage heights have since been obtained by measuring with a graduated rod from 

bridge deck to water surface. Gage datum unchanged.

DISCHARGE MEASUREMENTS. Made from three-span bridge.

CHANNEL AND CONTROL. Bed sandy and very shifting; broken by two bridge piers. 

No well-defined control.

EXREMES OP DISCHARGE. Maximum mean daily discharge during year, 11,000 

second-feet on October 15; no flow August 16 to 18, August 22 to September 15, 

September 24 to 30.

DIVERSIONS. Considerable water diverted for irrigation above station.

ACCURACY. Stage-discharge relation not permanent; not affected by ice. Owing to 

shifting control determinations of daily discharge are based almost entirely on 

frequent current-meter measurements.

COOPERATION. Records furnished by United States Reclamation Service and reduced to three significant figures by United States Geological Survey.

Aug. 2,1908, not included. Figures given for discharge above 90 secondPECOS HIVES AT CARLSBAD, N. HEX.

LOCATION. In SE. i sec f 6, T. 22 S., R. 27 E., at Gr^en Street Bridge in Carlsbad,

Eddy County, 300 feet downstream from Atchisori, Topeka & Santa Fe Railway

station, 1,500 feet above mouth of Dark Canyo4, 2,000 feet below Hagerman

dam.

DRAINAGE AREA. Not measured. 

RECORDS AVAILABLE. May 28,1903, to March 31,190fe; May 13,1914, to September

30, 1917. 

GAGE. Vertical staff attached to upstream side of middle bridge pier, installed May

18, 1914; gage used from May 28, 1903, to October, 1904, was an inclined staff

gage at the present site. From October, 1904, to March 31, 1908, vertical staff

gage at the same site was used.

DISCHARGE MEASUREMENTS. Made by wading or frorn bridge. 

CHANNEL AND CONTROL. Bed composed of gravel ind rock; nearly permanent,

but changes may occur after high stages and slight changes have taken place

during the lower steges. Banks of medium height; not subject to overflow.

Position of control not known. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.0 feet October

14 (discharge, 5,910 Second-feet); minimum stage, 0.50 foot July 24 (discharge,

26 second-feet). 

1903-1908, 1914-1017: Maximum stage recorded, about 21.0 feet August 7,

1916 (discharge, 85,700 1 second-feet); minimum ijitage, July 24,1917.

1 Discharge at Avalon dam; reported by engineers of United States Reclamation Service.
92 SURFACE WATER SUPPLY, 1917, PART VIII.

ICE. None reported during year.

DIVERSIONS. Large quantities of water are stored a few miles above station in Lakes 

McMillan and Avalon by the United States Reclamation Service for irrigating 

lands near Carlsbad. Water is also diverted for irrigation in valleys adjacent to 

river above Lake McMillan. Capacity of storage reservoirs in connection with 

the Carlsbad project, 58,500 acre-feet. Considerable water seeps into the river 

between the storage reservoirs and the gaging station, the quantity depending 

on the quantity being used for irrigation between the two points.

REGULATION. Flow at this point completely controlled by storage reservoirs of the 

Carlsbad project.

ACCURACY. Stage-discharge relation not permanent. Standard rating curve fairly 

well defined below 8,000 second-feet. Gage read to half-tenths once daily. One 

daily reading may not be a true index of the mean daily discharge because of 

fluctuation due to operation of storage reservoirs. Daily discharge ascertained 

by indirect method for shifting control. Records fair.

COOPERATION. Gage-height record furnished by United States Reclamation Service.

FEGOS RIVER NEAR ANGELES, TEX.

LOCATION. In T. 26 S., E. 29 E., just below Pecos Valley Railroad bridge crossing 

Delaware Creek at its mouth, 2 miles north of New Mexico-Texas State line, 2J 

miles southeast of Red Bluff, Eddy County, N. Mex., 8J miles northwest of 

Angeles, Reeves County, Tex.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 27,1914, to September 30,1917.

GAGE. Stevens continuous water-stage recorder, at first outcropping of rock on the 

right bank about 600 feet below railroad bridge and mouth of Delaware Creek.

DISCHARGE MEASUREMENTS. Made by wading or from cable half a mile downstream. 

Cable washed down in August, 1916; new cable installed in March, 1917.

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

not subject to overflow. Control formed by a series of rapids about 200 feet 

below the gage; shifts.

EXTREMES OP DISCHARGE. Maximum stage during year, from water-stage recorder, 

3.6£feet 3 p. m. October 14 (discharge, 3,860 second-feet); minimum discharge, 

June 20, 104 second-feet (gage height from water-stage recorder, 0.38 foot).

1914-1917: Maximum stage recorded, 21.5 feet 10 a. m. August 8,1916, measured 

by leveling from flood marks (discharge not determined); minimum discharge 

June 20,1917.

ICE. Stage-discharge relation not seriously affected by ice; open channel rating 

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 diversions are 

made for irrigation in the basin above the storage reservoirs of the Carlsbad project.

REGULATION. The operation of a water-power plant of 300 horsepower capacity above 

station, just below Carlsbad, N. Mex., does not materially regulate flow at gage. 

The flow is, however,, regulated to a large extent by waters stored in the reservoirs 

of the Carlsbad project. In the season of irrigation the effect of the regulation 

is decreased by return seepage waters, but during the winter the flow depends 

on water released at the reservoirs.
94 SURFACE WATER SUPPLY, 1917, PART VIII.

ACCTTRACY. Stage-discharge relation not permanent. Standard rating curve, used 

for computing daily discharge by shifting-control method, fairly well denned 

between 140 and 4,500 second-feet. Gage-height record not continuous due to 

imperfect operation of recorder. Mean daily gage height obtained by inspecting 

recorder graph, or, for days of considerable fluctuation, by averaging the hourly 

gage heights. Records fair October 1, to February 28, and August 26 to September 14; good, March 1 to August 25, and September 15-30.

Discharge for September, 1916, has been revised by means of measurements 

made in 1917. The determinations published herewith supersede those published in Water-Supply Paper 438.

PECOS RIVER ABOVE BARSTOW, TEX.

LOCATION. Three-quarters of a mile below head gate of Biggs irrigation project, 1 mile 

east of Patrole siding on Pecos Valley Railway, 1J miles above head gate of Barstow 

Irrigation Co., 14 miles northwest of Barstow, Reeves County, 10 miles northwest 

of Pecos.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. February 1, 1916, to September 30,1917.

GAGE. Stevens water-stage recorder on right bank.

DISCHARGE MEASUREMENTS. Made by wading or from cable 150 feet below gage.

CHANNEL AND CONTROL. Channel straight 100 feet above and 300 feet below station. 

Bed composed of gravel, clay, and sand; not permanent. Right bank is clay, 

clean, and fairly permanent; left bank loose and covered with salt cedar; both 

banks are overflowed at gage height about 10 feet. Shoal 250 feet below gage serves 

as control; shifts during high water.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage recorder, 

9.7 feet October 15 (discharge, 2,820 second-feet); minimum discharge June 24, 

22 second-feet (gage height from water-stage recorder, 0.88 foot).

1916-1917: Maximum stage, from water-stage recorder, 12.1 feet at 6 a. m. 

August 10, 1916 (discharge not determined); minimum discharge, June 24, 1917.

ICE. None reported during year.

DIVERSIONS. In addition to water stored and lands irrigated in New Mexico by the 

Carlsbad project of the United States Reclamation Service, some lands in Texas 

are irrigated just above the station. Considerable water is returned to the river 

by seepage below the reservoirs. The Second Report of the Board of Water Engineers for the State of Texas shows that 28,800 acres were declared irrigated above 

the station, the quantity of water necessary under an assumed duty of 3 acre-feet 

per acre being 86,400 acre-feet.

REGULATION. Storage in connection with the Carlsbad project controls the run-off 

during parts of the year. The operation of a water-power plant of 300-horsepower 

capacity, below Carlsbad, does not affect the flow at this point.
96 STJEFACE WATER SUPPLY, 1917, PAET VIH.

ACCURACY. Stage-discharge relation not permanent. Standard rating curve well 

defined below 700 second-feet and poorly defined above. Mean daily gage height 

determined by inspecting recorder graph or, for days of considerable fluctuation, 

by averaging the hourly gage height. Breaks in gage-height records caused by 

collections of silt in float box. Daily discharge ascertained by shifting-control 

method. Determinations of discharge during extremely high stages is subject to 

error caused by water flowing over both banks. Records good for periods during 

which water-stage recorder operated satisfactorily.

PECOS RIVER NEAR GRANDFALLS, TE3C.

LOCATION. At site of old highway bridge where Grandfalls-Fort Stockton road formerly crossed Pecos River 1$ miles upstream from present Grandfalls-Fort Stockton road crossing at Iron Bridge, 2 miles below diversion dam for silt-line canal 

of Imperial Irrigation Co., about 3 miles south, of Grandfalls, Ward County, 4$ 

miles above diversion dam of Zimmennan project, 21 miles south of Monahans.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. November 6,1915, to September 30,1917. Records were taken 

at Iron Bridge, 1J miles downstream, from November 6, 1915, to August 3, 1917. 

Discharge at both points believed to be the same.

GAGE. Stevens water-stage recorder, installed August 9, 1917, on downstream side 

of old bridge pier near left water's edge. Prior to August 3 a Stevens waterstage recorder at Iron Bridge. Backwater from Zimmennan dam compelled the 

relocation of the station.

DISCHARGE MEASUREMENTS. Made by wading 500 feet above station, from cable 50 

feet above gage, or during extremely high stages, at Iron Bridge.

CHANNEL AND CONTROL. Bed of stream solid rock, clean, smooth, and permanent. 

Channel straight for 100 feet above and below station. One channel below gage 

height of 8 feet; above this stage both, banks which are dirt and wooded are subject 

to overflow. Rock ledge extending diagonally across stream just below gage serves 

as low-water control.

EXTREMES OF DISCHARGE. Maximum stage recorded during the year, from waterstage recorder, 8.10 feet, 6 p. m. October 16 (discharge, 1,640 second-feet); minimum discharge, 3.9 second-feet, May 31 (gage height from water-stage recorder, 

2.49 feet).

1915-1917: Maximum stage, from water-stage recorder, 12.8 feet at 8 a. m. 

August 29, 1916 (discharge, 4,370 second-feet; determined from extension of 

rating curve and possibly subject to considerable error); minimum stage, 0.38 

foot at 1 a. m. April 17, 1916 (discharge not determined, but less than 0.7 

second-foot).

ICE. None reported during year. 

93838° 19 WSP 458 1
98 SURFACE WATER SUPPLY, 1917, PART VIII.

DIVERSIONS. Station is 2 miles below diversion of silt-line canal of the Imperial 

Irrigation Co., 18| miles below diversion for the Imperial reservoir (17,000 

acre-feet capacity), 15| miles below diversion for Grandfalls project and 4J miles 

above diversion for Zimmerman project. Available data show that tracts aggregating approximately 143,000 acres are irrigable between station and lower limits 

of Carlsbad project of United States Reclamation Service. Second Report of 

Board of Water Engineers for the State of Texas shows total number of acres 

declared irrigated in Texas above the station to be about 58,000, the amount of 

water required under an assumed duty of 3 acre-feet per acre being 174,000 acrefeet. The effect of diversions is somewhat counterbalanced by water returned 

to stream by seepage.

REGULATION. None.

ACCURACY. Stage discharge relation permanent at present site, but subject to 

changes in control and effect of backwater at former site. Rating curve well 

defined below 3,200 second-feet for Iron Bridge station and below 75 second-feet 

feet at present site. Gage-height record somewhat fragmentary, owing to stopping of water-stage recorder. Gage read once daily to hundredths; November 9 

to January 9, recorder not in working order. Mean daily gage height obtained 

by inspecting recorder graph or, for days of considerable fluctuations, by use 

of planimeter. Daily discharge ascertained by applying mean daily gage height 

to rating table as indicated in footnote to table of daily discharge. Records fair, 

October 1 to May 11, and August 9 to September 30; poor May 12 to August 8.

100 SURFACE WATER SUPPLY, 1917, PART VIII.

PEOOS RIVER NEAR COMSTOCK, TEX.

LOCATION. At Pecoe high bridge of Galveston, Harrisburg & San Antonio Railway 

Co., 11 miles west of Comstock, Val Verde County, 18 miles east of Langtry, 14 

miles by stream above confluence with Rio Grande, and below all tributaries.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 1, 1900, to September 30, 1917. (Also gage heights for 

1898.)

GAGE. Vertical staff attached to the downstream side of bridge pier on left bank, 

read by W. A. Clare.

DISCHARGE MEASUREMENTS. Made from cable 1,000 feet above bridge.

CHANNEL AND CONTROL. Banks and stream bed composed of rock and gravel; water 

flows through a series of rapids and pools in a canyon approximately 300 feet deep; 

banks not subject to overflow. Stage-discharge relation at the lower stages 

changes slightly.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.65 feet at 8 a. m. 

May 12 (discharge, 1,590 second-feet); minimum stage, 0.01 foot several days in 

August (discharge, 145 Second-feet).

1900-1917: Maximum stage recorded, 35.75 feet April 6, 1900 (discharge not 

determined); minimum discharge recorded, 110 second-feet May 13, 14, 1904 

(gage height 0.5 foot).

ICE. None reported during year.

DIVERSIONS. Considerable water is diverted and stored above the station for irrigation. Lake McMillan and Lake Avalon of 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. In addition to the water stored 

in New Mexico, water from Pecos River is used to irrigate large areas of land in 

the vicinity of Barstow and Grandfalls, Tex. There are no diversions below the 

station. Return waters tend to equalize effects of diversions in lower part of 

drainage basin.

REGULATION. Yearly run-off at this point controlled by storage and diversions for 

irrigation above station. No water-power plants of any consequence operated in 

the drainage basin, except a public utility plant of about 300 horsepower, near 

Carlsbad, N. Mex.

ACCURACY. Stage-discharge relation subject to changes. Rating curve well defined 

between 100 and 4,000 second-feet. Gage Tead to hundredths twice daily; mean 

of two readings may not be a true index of mean daily discharge. Daily discharge 

ascertained by applying mean daily gage height to rating table as indicated in 

footnote to table of daily discharge. Records good.

Sept. 30, 1917.

STREAM-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 

monographs.

The results of stream-flow measurements are now published annually in 12 parts, each part covering an area whose boundaries 

coincide with natural-drainage features as indicated below:

Part I. North Atlantic basins.

II. South Atlantic and esatern Gulf of Mexico basins.

III. Ohio River basin.

IV. St. Lawrence River basin.

V. Upper Mississippi River and Hudson Bay basins.

VI. Missouri River basin. 

VII. Lower Mississippi River basin. 

VIII. Western Gulf of Mexico basins. 

IX. Colorado River basin. 

X. Great basin.

XI. Pacific basins in California.

XII. North Pacific slope basins, in three volumes:

A. Pacific slope basins in Washington and Upper Columbia River basin.

B. Snake River basin.

C. Lower Columbia River basin and Pacific slope basins in Oregon.

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 

1917. 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, Me., 

1903 to 1917, are published in Water-Supply Papers 97, 124, 165, 

201, 241, 261, 281, 301, 321, 351, 381, 401, 431, and 451, which contain records for the New England streams from 1903 to 1917. Results 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. All 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.

In exception to this rule the records for Mississippi River are 

given in four parts, as indicated on page iii, and the records for 

large lakes are taken up in order of streams around the rim of the 

lake.

PART VUL 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

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 descriptions 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 geological 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 levels 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 area 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 

orders. This rate applies to folios in stock from 1 to 184, inclusive, also to the library 

edition of folio 186. The library edition of folios 185, 187, and higher numbers sells 

for 25 cents a copy, except that some folios which contain an unusually large amount 

of matter sell for 50 cents a copy. The octavo edition of folio 185 and higher numbers 

sells for 50 cents a copy. If 34 folios selling at 25 cents each (or their equivalent in 

higher-priced folios) are ordered at one time a discount of 40 per cent is allowed; 

$5.10 is the minimum amount accepted at this rate.

All the folios contain descriptions of the drainage of the quadrangles. The folios 

in the following list contain also brief discussions of the underground waters in connection with the economic resources of the areas and more or less information concerning the utilization of the water resources.

An asterisk (*) indicates that the stock of the folio is exhausted.

i 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, Washington, D. C.
