SURFACE WATER SUPPLY OF WESTERN GULF OF 

MEXICO BASINS, 1916.

AUTHORIZATION AND SCOPE OP WORK.

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

measurements of flow made on streams in the United States during 

the year ending September 30, 1916.

The data presented in these reports were collected by the United 

States Geological Survey under the following authority contained in 

the organic law (20 Stat. 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 bills passed by Congress have 

carried the following item and appropriations:

For gaging the streams and determining the water supply of the United Str.tes, and 

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

Annual appropriations for the fiscal years ending June 30, 1895-1917.

In the execution of the work many private and State organizations 

have cooperated either by furnishing data or by assisting in collecting 

data. Acknowledgments for cooperation of the first kind are made 

in connection with the description of each station affected; cooperation of the second kind is acknowledged on page 12.

Measurements of stream flow have been made at about 4,100 points 

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

Hawaiian Islands. In July, 1916, 1,290 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, 1916, PART VIII.

connection with this work data were also collected in regard to precipitation, evaporation, storage reservoirs, river profiler, 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 of inches, acre-feet, and millions of 

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

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

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

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

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

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

velocity of 1 foot per second. It is generally used as a fundamental 

unit from which others are computed by the use of the factors given 

in the tables of convenient equivalents (pp. 7 to 9).

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

of water flowing per second from each square mile of srea 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 ar 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 of inctes.

An "acre-foot," equivalent to 43,560 cubic feet, is the quantity required to cover an acre to the depth of 1 foot. The term is commonly used in connection with storage for irrigation.

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

in reservoirs, most frequently hi connection with studies of flood 

control.

The following terms not in common use are here defir.ed:

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

of gage height to discharge."

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

stream below the gage which determine the stage-discharge relation 

at the gage. It should be noted that the control may not be the same 

section or sections at all stages.
CONVENIENT EQUIVALENTS.

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

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

fall if there were no flow.

CONVENIENT EQUIVALENTS.

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

computations:

EXPLANATION OF DATA.

The data presented in this report cover the year beginning October 

1, 1915, and ending September 30, 1916. 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 Fin-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.
10 ST7BFACE WATEB SUPPLY, 1916, PART VIII.

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 measurer lents rating tables are prepared that 

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

to the gage heights, give the disc harge from which the daily, monthly, 

and yearly mean discharge is determined.

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

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

of discharge measurements, a table showing the daily discharge of 

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

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

tables giving daily gage heights and results of discharge measurements are published.

The description of the station gives, in addition to statements 

regarding location and equipment, information in regard to any conditions that may affect the constancy of the 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 amc1 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 diurnalfluctuation the discharge obtained from the rating table and the mean 

daily gage height may not be the true mean discharge for the day. 

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 for each second during the month. On this 

average flow computations recorded in the remaining columrs, which 

are defined on page 8, are based.

The deficiency table presented for some of the gaging stations 

shows the number of days hi 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 trble and, 

also by sub traction, 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 abo given. 

For convenience the theoretical horsepower per foot of fall corresponding to the discharge is given in the table on page 8. In using the 

table for studies of power, allowance should be made for the various 

losses, the most important being wheel loss and head loss.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS.

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

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

observation of stage, measurements of flow, and interpretation of 

records.

A paragraph in the description of the station or footnotes added to 

the tables gives information regarding the (1) permanence of the stagedischarge 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 heigl ts to the 

rating table to obtain the daily discharge.1

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

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

within 10 per cent; "poorly defined," within 15 to 25 per cent. 

These notes are very general and are based on the plottir^ 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 ti^e gage, but the figures 

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

may be subject to gross errors caused by the inclusion of large noncontributing districts in the measured drainage area, by lack of 

information concerning water diverted for irrigation or other use, 

or by inability to interpret the effect of artificial regulaticn 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

1 For a more detailed discussion of the accuracy of stream-flow data see Grover, N. C., and Hoyt, J. C., 

Accuracy of stream-flow data: U. S. Geol. Survey Water-Supply Paper 400, pp. 53-59,1916.
12 SURFACE WATER SUPPLY, 1916, PART VIII.

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 possi^e inherent 

sources of error not known to the Survey.

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

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

estimates; the tables of daily discharge allow more detailed studies 

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

the observations in each succeeding year may be expected to throw 

new light on data previously published.

COOPERATION.

During the year ending September 30, 1916, the work of measuring 

streams in Texas was carried on under cooperative agreement with 

the Director of the Federal Survey and the Board of Wate^ Engineers 

for the State of Texas, consisting of J. C. Nagle, chairman, John 

Wilson, and E. B. Gore.

Special acknowledgments are due to the United States Reclamation 

Service and the United States Weather Bureau for equipment used 

and assistance rendered in Pecos River valley, upper Trinity and 

Brazos River basins, and Colorado River basin. The United States 

Weather Bureau furnished a large part of the equipment for the 

evaporation station near Austin.

The United States Indian Office paid the greater part of the observer's salary at the stations near Taos.

The following cities, organizations, private companies, and railroads 

have aided in the collection of records by furnishing funds or otherwise assisting: City of San Angelo; city of Corpus Christi; Cuero 

Commercial Club; San Marcos Utilities Co.; Barstow Irr^ation Co.; 

Imperial Irrigation Co.; Arlington Land Co.; Kansas City, Mexico & 

Orient Railroad; San Antonio, Uvalde & Gulf Railroad Co.; Pecos 

Valley Lines; Texas & Pacific Railway; Gulf, Colorado & Santa Fe 

Railway; and International & Great Northern Railway.

DIVISION OF WORK.

The data for stations in Texas were collected and prepared for 

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

who was assisted by H. J. Dean, assistant engineer; R. C. Pierce and 

William Kessler, junior engineers; and R. C. Thaxton, Russell J. 

Hank, Victor Lieb, and W. C. Dodd, State hydrographerp.

The data for stations in the Rio Grande drainage brsin in New 

Mexico were collected and prepared for publication under the direction of Robert Follansbee, district engineer, who was assisted by

GAGING-STATION RECORDS.

TRINITY RIVER BASIN.

TRINITY RIVER AT BRIDGEPORT, TEX.

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

Rock Island & Gulf Railway Co. pumping plant, and 1 mile below mouth of 

Gentry Creek. *

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

RECORDS AVAILABLE. October 1, 1914, to September 30, 1916. Record of stage has 

been obtained by United States Weather Bureau from August 16, 1908, to October 16, 1915.

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

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

DISCHARGE MEASUREMENTS. Made fipm downstream side of bridge or by Trading.

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

slightly wooded, and are overflowed at a stage of 25 feet. Channel straight 

above and below station for 100 feet. Control is a rock outcrop three-quarters 

of a mile below station.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 22.70 feet at 

6 p. m. April 2 (discharge, 10,800 second-feet); no flow October 8-11.

1908-1916: Maximum stage recorded, .28.9 feet June 8, 1915 (disci %rge not 

determined); no flow October 8-11, 1915.

ICE. None reported during year.

DIVERSIONS. None above station for power development; extensive irrigation not 

required, as ordinarily the precipitation in the drainage bas|n is sufficient to 

mature crops. The operation of the few small pumping plants' along tl 3 stream 

produces little noticeable effect. j

REGULATION. Flow unaffected by water-power plants, dams, or| reservoirs above 

or immediately below the station. ;

ACCURACY. Stage-discharge relation changes slightly. Rating cuirve well defined. 

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

mean-daily gage heights to rating table, except for periods during whi"h stagedischarge relation was affected by shifting control. Results good except, for low 

water for which they are fair.

Timmons.

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

CHANNEL AND CONTROL. Channel straight above and below station. Bed 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 stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 9.50 feet at 6 p. m. 

April 2 (discharge, 4,100 second-feet; result obtained from extension cf rating 

curve and possibly subject to considerable error); no flow March 29 and 30, and 

August 10-31.

ICE. Slight amount of ice reported in 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-height record does 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 heights to rating table 

except for periods during which stage-discharge relation is affected by shifting 

control. Determinations of discharge above 2,000 second-feet obtained from an 

extension of rating curve and subject to considerable error. Results poor.

BRAZOS RIVER AT BRAZOS, TEX.

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

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

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

RECORDS AVAILABLE. October 1, 1914, to September 30, 1916. Records o* stage

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

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

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

pier; read by L. W. Boyett. 

DISCHARGE MEASUREMENTS. Made from three-span highway bridge about 6"^ feet

below railway bridge. 

CHANNEL AND CONTROL. Bed composed of sand and gravel; skifts slightly at low

water. Right bank high, rocky, wooded, and not subject to overflow; left bank

composed of sand, gravel, and clay, wooded, 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, 9.60 feet at 7

a. m., April 2 (discharge, 42,500 second-feet; result obtained from extension of

rating curve and possibly subject to considerable error); minimum stage, no flow

August 25 to September 1. 

1908-1916: Maximum stage recorded, 22.0 feet May 24, 1908 (discharge not

determined); no flow for several periods within limits of observations. 

ICE. None reported during year. 

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 irrmediately below station. Swamps and natural lakes are rare in the drainage basin

above the station. 

ACCURACY. Stage-discharge relation not permanent. Two rating curves each

fairly well defined below 18,000 second-feet, were used during the year. Gage

read to half-tenths once daily. Daily discharge ascertained by applying daily

gage heights to rating tables. Results fair. Determinations for extremely high

stages obtained from extension of the rating curve and may be consic'erably

in error. 

COOPERATION. Record of gage height October 1-19 furnished by the United States

Weather Bureau.

BRAZOS RIVER AT WACO, TEX.

LOCATION. At suspension bridge on Bridge Street, in city of Wa?o, McLennan 

County, just below Southern Traction Co.'s bridge, 2J miles b?low mouth of 

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

lock No. 8, now under construction.

DKAINAGE ABEA, 25,500 square miles (revised).
BRAZOS RIVEE, BASIIST. 19

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

to September 30, 1916. 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.

DISCHARGE MEASUREMENTS. 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.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 33.8 feet at 8 a. m. 

April 2 (discharge, 113,000 second-feet; result obtained from extension of rating 

curve possibly subject to large error); minimum stage, 5.48 feet August 30 and 

31 and September 1 and 2 (discharge, 119 second-feet).

1889-1916: Maximum stage recorded, 39.7 feet December 3, 1913 (discharge not 

determined); minimum stage, 2.00 feet March 8-10, 1902 (discharge, 20 secondfeet).

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. Lock No. 8 will eventually control flow at this station; flow only 

slightly controlled at present.

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

ascertaining discharge by indirect method is fairly well defined. Gage read to 

quarter-tenths once daily. Slight errors may be introduced by taking one daily 

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

method for shifting control. Results fair.

COOPERATION. Record of gage heights October 1-23 furnished by United States 

Weather Bureau.

CLEAR FORK OF BRAZOS RIVER NEAR ELIASVILLE, TES.

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

Young County, 4J miles southwest of South Bend, 6 milea above oouth of 

stream, and below all tributaries.

DRAINAGE AREA. 5,650 square miles.

RECORDS AVAILABLE. November 12, 1915, to September 30, 1916.

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

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

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

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

dhannel straight above and below station. A shoal about 600 feet belo'w station 

serves as control for low and medium stages; control shifts slightly durir.s changEXTREMES OF DISCHARGE. Maximum stage recorded during year, 18.2 feet 

6 p. m. May 2 (discharge, 7,800 second-feet; result obtained from extension of 

rating curve and possibly subject to considerable error); no flow August 23 to 

September 30.

ICE. None reported during year.

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

counties. Two diversions are made for irrigation between station and confluence 

of Clear Fork with Brazos River. Quantity of water diverted unknoTi. According to the First Report of the Board of Water Engineers for the State of 

Texas, the Sweetwater Light & Power Co. has filed on 100 acre-feet of water for 

storage in the headwater region.

REGULATION. No large reservoir above or below station. The operation of a waterpower gristmill 5 miles upstream produces some effect at the station.
22 SURFACE WATER" SUPPLY, 1916, PART VIII.

ACCURACY. Stage-discharge relation not permanent. Rating curve fairly well defined beiow 2,000 second-feet and poorly defined above. Gage read to hundredtlis 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 heigl t to rating table 

except for periods during which stage-discharge relation is affected by shifting 

control. Results fair.

COLORADO RIVER BASIN. 

COLORADO RIVER NEAR BRONTE, TEX.

LOCATION. At wagon bridge 400 feet below Kansas City, Mexico & Orient Railroad 

bridge 1J milea above mouth of Kickapoo Creek and below mouth of Live Oak 

Creek, 2J miles south of Bronte, Coke County.

DRAINAGE AREA. 5,550 square miles.

RECORDS AVAILABLE. September 19, 1915, to September 30, 1916.

GAGE. Chain gage attached to downstream side of bridge near left bank; read by 

R. W. Legg. A vertical staff gage attached to left bent of railroad bridge 400 feet 

above present site and referred to same datum was used from September 19, 1915, 

to October 29, 1915.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge or by \rading.

CHANNEL AND CONTROL. Bed composed of a clay hardpan mixed with gravel; shifts. 

Channel straight about 500 feet above and below station. Right bank wooded, 

sloping, and subject to overflow at extreme stages; left bank high, clean, and not 

subject to overflow. Control probably at shoal 300 feet below gage.

EXTREMES OF DISCHARGE. 1915-16: Maximum stage recorded during year* 15.0 feet 

at 2 a. m. September 25, 1916 (discharge not determined); no flow M?y 13-29, 

June 8 to July 29, and August 6-21.

ICE. None reported during year.

DIVERSIONS. Some water is diverted for irrigating small areas in Coke and Mitchell 

counties and for municipal use of the city of Robert Lee. No large irrigation 

projects in drainage basin above station. The First Report of the Board of Water 

Engineers for the State of Texas records a filing at Robert Lee on a small quantity 

of water for storage, but this storage will not influence flow at station.

REGULATION. Flow not affected by water-power plants or controlling works.

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

below 400 second-feet and is an extension above 450 second-feet. Gag? read to 

hundredths twice daily. Daily discharge ascertained by applying mean daily 

gage heights to rating table except for periods during which stage-discharge 

relation is affected by ice. Results fair.

COLORADO EIVEE BASIN.

COLORADO RIVER AT BALLINGER, TEX.

LOCATION. At Hutcliins 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, 1916. Records of stage 

have been obtained by the United States Weather Bureau since July 1, 1903. 

Current-meter measurements were begun May 29, 1915.

GAGE. Chain gage attached to downstream handrail of bridge; read by E. M. Eubank.

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

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 f?et below 

gage; subject to change.

ICE. None reported during year.

EXTREMES OP DISCHARGE. Maximum stage recorded during year 9 feet al 9 a. m. 

September 25 (discharge, 6,300 second-feet; result obtained from extension of 

rating curve and possibly subject to considerable error). No flow July 3 to August 

26 and September 16-24.

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

by gravity or by pumping, but the quantity diverted is small in comparison with 

tke total run-off.

REGULATION. No artificial regulation above station.

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

defined below 600 second-feet and is an extension above that discharfe. Gage 

read to hundredths once daily; readings for some days questionable. Daily discharge ascertained by applying daily gage heights to rating table except for 

periods during which stage-discharge relation is affected by shifting control. 

Results below 1,000 second-feet are fair; above 1,000 second-feet they may be 

subject to considerable error.

COLORADO RIVER BASIN. 27

COLORADO RIVER NEAR CHAD WICK, TEX.

LOCATION. At the 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 county line between San Saba and Lampasas counties, and 2£ miles below 

mouth of San Saba River.

DRAINAGE AREA. 26,400 square miles.

RECORDS AVAILABLE. October 21, 1915, to September 30,1916.

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

feet upstream from railroad 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.

DISCHARGE MEASUREMENTS. Made from cable 400 feet below gage.

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, 

wpoded, 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 OF DISCHARGE. Maximum stage recorded during year, 15.0 feet at 7 a.m. 

May 2 (discharge, 16,900 second-feet; result obtained from extension of rating 

curve and possibly subject to considerable error); minimum stage, 0.6" foot at 8 

a. m. August 27 and 28 (discharge 30 second-feet).

ICE. None reported during year.

DIVERSIONS. No large irrigatioa 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 Sf.ba 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 c'Trve well 

defined between 80 and 4,000 second-feet. Gage read to hundredths once daily. 

Daily discharge ascertained by applying daily gage heights to rating table. 

Results good below 4,000 second-feet; above 4,000 second-feet may be subject to 

error due to lack of current-meter measurements.

COLORADO RIVER BASIF. 29

COLORADO RIVEE. AT AUSTIN, TEX.

LOCATION. At the Congress Avenue concrete viaduct in Austin, Travis County, 

half a mile below Shoal Creek and above mouth of Waller Creek 3J miles below 

Austin dam.

DRAINAGE AREA. 34,200 square miles (revised).

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

September 30,1916; September 1,1895, to April 7,1900, at Austin Dam. Records 

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

1903.

GAGE. Dexter water-stage recorder, installed June 18, 1915, at left end of concrete 

viaduct. Record of depth of water on crest of dam 3J miles above Austin was 

kept 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 b^nk 150 

feet above Congress Avenue Bridge; during this period high-stage readirgs 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 Mcntopolis 

highway bridge, 4 miles downstream.

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

station. 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 bekrw gage; 

changes during high water and also during low water because of the removal of 

sand for municipal use.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 13.1 feet at 4 a. m., 

May 22 (discharge, 46,000 second-feet); minimum stage, 0.30 foot at 7 a. m., 

September 21 (discharge, 80 second-feet).

1898-1911; 1914-1916: Maximum stage recorded, 33.5 feet April 7, 1900 (discharge, 122,000 second-feet); minimum stage, 0.50 foot December 13-17, 1914 

(discharge, 2 second-feet).

ICE. None reported during year.

DIVERSIONS. The first report of the Board of Water Engineers for the State cf Texas 

shows that approximately 35,000 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, 144 acre-feet per annum for Winchell waterworks, QQ,Q'V) acr»- 

feet per annum for power from two reservoirs in Burnet County, and an unknown 

amount for Marble Falls waterworks, all above station. Much of the area irrigated 

is in the upper basim of the main stream and adjacent to large tributaries

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

miles upstream.

ACCURACY. Stage-discharge relation not permanent. Numerous discharge n^asurements are necessary to determine changes in stage-discharge relation. Standard 

rating curve is well defined below 40,000 second-feet. Error in determinations 

of mean daily discharge due to regulation of flow eliminated by use of s. waterstage recorder. Mean daily gage heights, to half-tenths, obtained by inspecting 

the recorder graph, or, for days of considerable fluctuation, by averaging hourly 

gage heights. Daily discharge ascertained by indirect method for shifting 

control. Results good.

COLORADO RIVER AT COLUMBUS, TEX.

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

Galveston, Harrisburg & San Antonio Railway bridge in eastern edg^ of Columbus, 

Colorado County.

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

RECORDS AVAILABLE. August 2, 1902, to December 31, 1911; May 22, 1916, to September 30, 1916. Records of stage have been obtained by the United States 

Weather Bureau since January 1, 1903.

GAGE. Mott tape-and-weight gage, property of the United States Weather Bureau, 

installed December 17, 1907, on downstream handrail of bridge; read by W. E. 

Bridge. 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.

DISCHARGE MEASUREMENTS. Made from upstream side of bridge, or I y wading.

CHANNEL AND CONTROL. Channel straight above and below statior 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 OP DISCHARGE. Maximum stage recorded during year, 24.7 feet from 9.50 

a. m. to 2.30 p. m. May 23 (discharge, 36,800 second-feet); minimum stage, 6.38 

feet at 7 a. m. and 6 p. m. September 25 (discharge, 278 second-feet).

1902-1911; 1916: 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.

DrvEMsiONS. Considerable water is diverted for irrigation in the drajuage bw*

Austin, bnt between Austin and Columbus little water is pumped or diverted by 

gravity. The station is above file irrigated rice belt, which comprise several 

thousand acres. Filings have been made with the Board of Water JBngiae«~«for the 

State of Texas far continuous use of water for Smithville, Bastrop, and LJV Grange 

waterworks, all above station.

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

Austin.

AOCUBACT. -Stage^iseharge reJajfcbn not permanent. Rating curve i*@U defined 

below 46,080 geeond-i@et. Gage read to hundredtha twice a day. Mean of two 

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

station. Daily discharge ascertained by applying mean daily gage heights torating table except lor periods during which stage-discharge relatipn is affected 

by shifting control. Besmltsfood.

for 800 feet above and 400 feet below gage. Banks are sloping, clean, composed 

of rock and clay, and not subject to overflow except during high fl*x>ds. About 

20 feet below g^ge and at downstream side of viaduct is a concrete dam 4) 

feet high, which, before the viaduct was constructed, served as js**fc .of a lowwater crossing; this dam forms an artificial control and insures a pern&aent stagedischarge relation.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 1.9^ feet at 5.25 

p. m. April 14 (discharge, 465 second-feet; result obtained from extension of rating 

curve and possibly subject to some error); no flow June 5-14 arid Jrne 22 to September 30.

ICE. None reported during year.

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

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

REGULATION. Flow not regulated by water-power plants or i*serw&iM

ACCURACY. Stage-discharge relation permanent. Rating curse wett jf^fiawl below 

but possibly subject to error above 200 second+fgejt. Gage read t- hundredth^

CONCHO RIVER NEAR SAN ANGELO, TEX.

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

If miles southeast of San Angelo, Tom Green County.

DRAINAGE AREA. 10,800 square miles.

RECORDS AVAILABLE. September 17,1915, to September 30,1916.

GAGE. Vertical staff in several sections attached to trees on left bank about 1,500 

feet below an old ford; read by Mrs. B. H. Cummins.

DISCHARGE MEASUREMENTS. Made by wading or from cable 80 fee4; below 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 higl stages. Rapids 

about 100 feet below the gage serve as control for medium and low stages; do not 

shift; position of control for high stages not known.

EXTREMES OF DISCHARGE. 1915-16: Maximum stage recorded, 135 feet during the 

night of September 24, 1915 (discharge not determined); minimum stage, 0.50 

foot at 11 a. m. June 24,1916 (discharge, 2.3 second-feet).

ICE. None reported during year.

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

immediately below. First Report of the Board of Water Engineers for the State 

of Texas shows a total of 25,000 acre-feet per annum is taken from the stream. 

About a mile above mouth of South Concho River a storage dam has been constructed by the San Angelo Light & Power Co. for waterworks, frit 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 & Pov^r Co. has slight 

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

ACCURACY. Stage-discharge relation practically permanent. Rating curve welldefined below 250 second-feet. Gage read to hundredths once daily. 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 heights to rating table. Results are good during medium stages, 

fair during extreme low stages, and poor during h|gh stages; determinations of 

discharge above <WO second-feet may be considerably in error.

40 SUBFACE WATEB SUPPLY, 1016, PABT.

GAGE. Chain gage attached to floor on downstream aide of highway t ~idge; read by 

Henry Patton.

DISCHARGE MEASUREMENTS. Made by wading or front downstream sHe of bridge.

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

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

obstructed by reeds and grass, but below thk gage it is clean and the flow is unobstructed. Bight bank composed of gravel a»d clay, wooded, sloping, high, and 

not subject to overflow; left bank similar in material, wooded, lew, 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, b'it shifts at extremely high stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 3 feet at 9 a. m. 

April 1 (discharge, 195 second-feet; result obtained by extension of rating curve 

and possibly subject to considerable error); minimum stage recorded, 1.76 feet 

at 6 p. m. August 16 and 4.20 p. m. August 17 (discharge, 6.8 serond-feet), obtained by extension of rating curve; determinations possibly sul *ect to considerable error. 

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

 (discharge not determined); minimum stage August 16 and 17, 1816 (see preceding paragraph).

ICE. None reported during year.

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

station. Noyes canal, on right side of river, carries water that is c1 *verted a short 

distance above gage. Several pumping plants are above and be?ow gage. The 

First Eeport of the Board of Water Engineers for the State of Texas shows that 

approximately 2,400 acres are declared irrigated above die station by 4,800 acrefeet of water per annum.

REGULATION. Flow unregulated by storage or water-power plants.

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

stages, but changes during high water. Rating curve well defined between 10 

and 100 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 table. Results excellent except for extreme st'flses, for which 

they may be considerably in error.

to September 30,1916. Miscellaneous discharge measurements previous to 1904.

GAGE. Vertical and inclined staff on right bank; read by J; M.Walker. FromDecember 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 kno^n.

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 only during high floods. Lef *, 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 75 feet below gage serves as control during 

medium and low stages; control is free from vegetation and doe? not shift during 

low and medium stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 15.7 feet during 

night of May 1 (discharge not determined); minimum stage, 1.10 feet at times 

during afternoon of July 5, 12, 13, and 15 (discharge, 20 second-feet).

1904-1906; 1915-16: Maximum stage recorded, 31.7 feet August 7, 1906 (discharge not determined); minimum flow, December 20, 1904, when discharge 

measurement showed 15 second-feet (gage not read).

ICE. None reported during year.

DIVERSIONS. Considerable water is diverted or pumped from the a*waa& and tributaries above station. There are also diversions below the etat'-m, I>ut none in 

the vicinity of the station. The First Report of the Board of Water Engineers 

for the State of Texas shows that 4,360 acres of land were declar^ irrigated,-and 

that approximately 8,700 acre-feet of water is used each year above station. Flood 

water from Brady Creek at Brady is stored for municipal uses; capacity of reservoir not known but probably small.

BEGTTLATION. Flow not regulated by dams or resermra.

ACCURACY. Stage-discharge relation permanent during low aad medium stages. 

Bating curve well defined between 20 and 300 second-feet; determinations above 

300 second-feet possibly subject to considerable error. Gag* read to hundredths twice daily; oftener during high water. Daily discharge ascertained by 

applying mean daily gage heights to rating table. Results excellent; -except 

during periods of high water.

LOCATION. One hundred feet north 6f KerrviHe^unctie& road, a quar^r of a mile 

noribeaB&d^fiteef^faseh bowse, 3 mles below eorttwwet-of NortVsnd South 

Llano rivers, -34 Jnilea east of Junction, Kimble Ckmnty, -4 miles above Johnson's Fork- Greek entering ^iver ffomihe south.

DRAINAGE AREA. 1, TOO square miles^

RECORDS AVAILABLE. September 13, 1915, to September 30, >1916.

GAGE. -^-Vertical staff, reading from 0 to 7.5 feet, attached to tree on rigl t 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 station.

CHANNEL AND CONTROL. Bed composed of solid rock, 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 is 

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 tint leaves the 

river a short distance above the gage, passes to the south of Oliver's ranch house, 

and «hters the main stream below the gage. Such* conditions do no*, occur, however, at intervals more frequent than 10 to 15 years and will not greatly affect 

results. Rock ledge about 75 feet below gage, forming a fall of approximately 

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

EXTREMES OF DISCHARGE. Maximum stage 'recorded during year, 8.F feet during 

night of May '21 (discharge not determined); minimum stage, 1.50 fe^tat 2 p. m. 

July 1, and 6 p. in. September 25 (discharge,! 46 second-feet).

1915-16: Maximum stage recorded, 26.3 feet at 3 a. m. September 16, 1915 (discharge not determined); minimum stage July 1 and September 25, 1916 (see preceding paragraph).

ICE .-"-None reported during year.

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

Texas shows that 4,281 acres of land have been declared irrigated requiring 8,562 

acre-feet of water annually from Llano River above the station on the assumption that the duty of water is 2 acre-feet per acre. Available datr, show that a 

large part of this land is in the vicinity of Junction", near the confluence of North 

and South Llano rivers, A filisg-of 600 second-feet for coettauotts use in connection with 'hydraulic fwwer <forite' Junction Gin and Waterworks is also listed in

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

AceiraACY.-+~St%e-discMarge relation practically permanent. Rating carve* weft^ 

defined between 40 and 300! second-feet. Gage read to hundredth^ once dafiyj 

during high, water oftener. Determinations of discharge above 401 second-feetmay be subject to error. Daily discharge ascertained by applying mean daily 

gage heights to rating table. Results excellent for medium and lor* stages.

GTTADALUPE RIVER BASIN. 

GUADALTTPE RIVER AT HEW BRAUHFELS, TEX.

LOCATION. Just below highway bridge on San Antonio-Austin pc«t road 700 feet 

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

Comal River, 1 mile northeast of center of New Braunfelfl, Coma1 County.

DRAINAGE AREA. 1,760 square miles.

RECORDS AVAILABLE. March 13, 1898, to December 30, 1899; Janr<wy 27, 1915, to 

September 30,1916.

GAGE. Vertical staff; three sections attached to trees on left ban! 200 feet below 

highway bridge and one section on east side of left pier of highv^y bridge; read 

by J. F. Willman. Gage used from March 13,1898, to December 30,1899, was an 

inclined staff gage near the present highway bridge; relation between datum of 

inclined gage and that of present gage not known.

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 sutfect to overflow. 

Rock and gravel shoal just below gage serves as control; subject t«> slight changes.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 20.8 feet at 7 p. m. 

May 22 (discharge, determined from extension of rating curve, 28,500 second-feet); 

minimum stage, 1.68 feet September 23 and 24 (discharge, 370 second-feet).

1898-99 and 1915-16: Maximum stage recorded, 27.2 feet at 9.f> p. m. September 17,1915, determined by leveling from flood marks (discharge not determined); 

minimum stage recorded, 1.70 feet September 27 to October 20, 1899 (discharge 

not determined, but according to discharge measurement of March 16, 1899, the 

flow was less than 358 second-feet).

ICE. None reported during year.

DIVERSIONS.- Some water diverted for irrigation above station in Kerr and Comal 

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 ef power plants. m

ACCURACY. Stage-discharge relation subject to slight changes. Br ting curve well 

denned below 7,000 second-feet. Gage read to tenths once da^'y October 1 to 

November 9 and to hundredths twice daily thereafter. 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 plants. Daily disci >rge ascertained 

- by applying mean daily gage heights to rating table, except fcr periods during 

which stage-discharge relation was affected by shifting control. Results good.

GTTADALTTPE RIVEIt HJE4SIJBOJKZAJJSS, TEX.

LOCATION. Just below Guadalupe highway bridge, 1J mites 8-mtb, of Gonzales, 

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

miles below mouth of San Marcos Biver.

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

RECORDS AVAILABLE. July 1, 1915, to September SO, 1916. 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 belor bridge; read by 

Albert Garcia. Relation between this gage and that of Unit ^d States Weather 

Bureau not known.

DISCHARGE MEASUREMENTS. Made from downstream side of lighway bridge or 

from cable one-fourth mile below gage.

CHANNEL AND CONTROL. Bed composed of gravel and sand; cl^a. but somewhat 

shifting; channel below station is straight for 500 feet, but abo^e is broken by an 

island and is straight for not more than 50 feet. Banks mad? up of grave! and 

clay; medium height; wooded along water's edge on the light and for some 

distance back on the left; subject to overflow only during extremely high stages. 

Position of control not known.

EXTREMES OF DISCHARGE. 1915-16: Maximum stage recorded, 2? 25 feet at 7 a. m. 

May 25, 1916 (discharge, 22,800 second-feet; result obtained from extension of 

rating curve and possibly subject to error); minimum stage, 1.07 feet August 

16 and 17 and September 18, 1916 (discharge, 452 second-fee*).

ICE. None reported during year.

DIVEBSIONS. -Some water diverted for irrigation above this point by gravity or 

pumping, but amount is small in comparison with the total rrn-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 ibis point regulated to a large extent by operation of waterpower plants in the drainage above. Construction work at tin dam of the Gonzales Water Power Co. causes a slight unnatural fluctuation.

ACCURACY. Stage-discharge relation not permanent. Standard rating curve fairly 

well-defined below 7,000 second-feet. Gage read^tohundredths 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 heights to rating table and by indirect 

method for shafting control. Results are fair except tfcev* t,4Jfl0 second-feet 

when they may be considerably in error because of poorly defined rating carve.

LOCATION. At Schleicher Bridge, 300 feet below San Antonio & Arcnsas Pass Railway bridge 2 toiles southwest of Cuero, Dewitt County, 4 miles below a dam used 

for power development.

DRAINAGE ARBA.-*-5,020 square ntO$8 (revised).

GAGE. Vertical statff; low-water section attached to piling under righ*; end of railway 

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

M. D. Alhiight. Gage used from December 26,1902, to July, 1903. was a verticalstaff gage at Carl Buchel's powerhouse, 3 miles north of Cuero. In July, 1903, 

the station was moved downstream to the San Antonio & Arams s Pass Railway 

bridge, and gage heights were obtained by measuring with a tagged line the 

distance from a reference point on the bridge to the water surface. Gage used 

from 1904 to 1906 was a chain gage at the railway bridge and was referred to the 

datum of the reference point, but. the relation between that datum and the datum 

of the present gage is not known.

DISCHARGE MEASUREMENTS. Made from upstream side of highway I ridge.

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

Bed composed oi rock, gravel, and sand; shifts. Left bank wooded, high, and 

not subject to overflow; right bank is of medium height, wooded, and is overflowed at extremely high stages. Position of control not known.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 19.5 feet 7 a. m. 

May 27 (discharge not determined); minimum stage, 3.1 feet at 7 a. m. April 30 

(discharge not determined).

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

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

ICE. None reported during year.

DIVERSIONS. Flow at this point not greatly affected by diversions above, as water 

is diverted in small amounts only.

KE&OTIATION. Flow regulated by operation of water-power plants uis**ream, ehiefiy 

by a plant about 4 miles above.

ACCURACY. Stage-discharge relation not permanent. Rating curve not developed. 

Gage read to huadredths twice daily. Mean daily gage height based on two 

readings may not be a true index ©f mean daily diachafg^iWcausr oi fluctuations 

caused by operation of pow#r plitots. Daily discharge not de*e£rined.

CHANITKB ANB CONTROL. Bed composed of gravel and sand; some vegetation in the 

flowing water. Channel straight for 280 feet above and below the station. 

Water very clear, deej>, and with scarcely any sediment except daring floods 

caused by local rains, Left bank wooded, high, and not subject to ov*> ow; 

right bank wooded, low, and subject to overflow, the water spreading bt «k 100 

feet to a second bank. Position of control not known; "current-meter measurements indicate that it changes slightly. x

EXTREMES or DISCHARGE. 1915-16: Maximum stage, from water-stage recorder 

4.05 feet at 2 a. m. April 16 (discharge, 365 second-feet), minimum stag© recorded, 

0.5S foot at 6 p. m. August 1 (discharge, 55 second-feet), determHiatkffle of both 

maximum and minimum discharge obtained from extension of rating cur^e and 

possibly subject to considerable error.

ICE. None reported during year.

DIVERSIONS. A concrete 4am just above the Saa 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 die water for irrigation and the wat T 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 is pumped to the south bank lands. Only pumping i %nt or 

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

gage. The First Report of the Board of Water Engineers for the State of Texas 

shows a fifing for this plant for a capacity of diversion works of 3 second-fe ->t, and 

irrigable area of 100 acres. This report also shows filings in Hayes County, which 

axe believed to be above the gage, of 789 acres declared irrigated by beneficial 

use of 1,578 acre-feet per annum. Beckman dam, just below mouth of Blanco 

River, ia used to impound water for irrigation. During ordinary stages in San 

.. Marcos and Blanco rivers this dam backs water up San Marcos River, a d^tance 

~ of three-quarters of a mile, but flood stages in Blanco River create bac1rwater 

at the station.

RBGTOAH0N.-*-F!ow>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 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 Cap? Ginning Co.'s mill during ginning season.

ACCURACY, Stage-discharge delation changes slightly; rating curve is fair}}* well 

defined from 100 to 240 second-feet. The periods of backwater from Blanco 

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

daily gage height determined by averaging 24-hourly readings .from recorder 

charts. Discharge determined by the indirect method for shifting t^uferol. 

Results good from March 13 to September 30, but poor prior to that period. The 

fluctuating stage and grass growth in the channel introdued large errors in results 

obtained previous to March 13.

SAN ANTONIO BIVEB BASIN. 

SAW A3TTOKZO HIVER AT SAN AKTONZO, 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 ABBA. Indeterminate. 

RECOBDS AVAILABLE. October 23, 1914, to September 30, 1916, SfaceUaneouB 

diachaige measurements -were made from 1895 to 1906,
SAJF 59

GAGE. Vertical staff attached- to upsttem^ttde of second beat of bridge ftor* right 

bank; read by E. L. Wilson. Gage used from October 23,1914, to Febrvwy 28, 

1916, was a vertical staff gage attached to downstream side of mMdle J»l^ pier, 

Commerce Street Bridge^ relation of the datums of these gages not knew? <,.

Di8CHAB<JB MKASUEBMENTS. Hade from downstream side of Market Street Bridge, 

first bridg* above station. .

CHANNSI. AK» ex)NTapL. bAnnel straight for & short distance abe*re and below 

static btit the general course is v«y crooked. Bed coaqMied »f g»we?> sand, 

and silt; shifts sl%htly. Banks h%h «ad dean; sot 8tib|e£t to #rerfi&r except 

during extremely high stages, at which time the river spnoda o^«r ft wk*^ area, 

A rock and gravel fihqal just below the station, free from vegetation and n-^t subject to extareme shiMag, serves as a control. i

EXTREMES of DI^HABGB.- Maximum stage recorded daring year, $40 feet rfc 10.45 

a. m,, September 25 (discharge, 2,650 second-feet), determined ft&a extern of 

rating curve and possibly subject to considerable error; miaimom stag"* 1.30 

feet March 15 to 23 (diBcharge, 72 second-feet).

1914-1016: Maximum stage recorded, 14.0 feet at 5.30 p. m,, October r 1914 

(discharge, 4,700 second-feet), determined from extension of rating cur"e and 

possibly subject to considerable error; imnfimBprn stage, 1.3Q feet, March 15 to 23, 

1916 (discharge, 72 second-feet). ,

ICE. None reported during year.

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

the city; quantity of water diverted not definitely known.

ACCURACY. Stage-discharge relation was affected during various period T from 

October 1,1915, to February 28,1916, by backwater from a small loose roe^ dam; 

on February 29 the gage was moved to its present location, where the relation ts 

subject only to slight changes. Eating curve well defined for first location and 

well defined below 360 second-feet for present location. Gage read to hundredth^ 

trice dafly. Bafly discharge ascertained by applying gage heights to rating 

tables except during periods when stage-discharge relation was affected by backwater. Results are good from March 1 to September 30,1016, and fair j^nor to 

that period. The normal flow of San Antonio River comes from springs within 

the city limits, but two tributaries from the north furnish considerable nr»-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, as it is thought that th" wells. 

draw from the underground reservoir that feeds the river by springs.

LOCATION. At suspension high way bridge near Oswald's ranch, 2milraeastof 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, 1916. 

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

bridge; read by C. C. Oswald. 

DISCHARGE MEASUREMENTS. Made by wading 100 feet below bridge or from downstream side of bridge. 

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

shifts. Banks high and wooded and not subject to overflow, .Channel straight

above and below station. Position of control not known, Th^ stage-discharge

relation has been seriously affected at times by collection of logs, leaves, and

brush below gage. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, If .2 feet at 7 p. m.

August 19 (discharge not determined); minimum stage, 1.85 feet from July 1 to

July 5 (discharge, 3.8 second-feet).

(discharge not determined); minimum stage, July 1-5, 1916 (see preceding 

paragraph).

ICE. None reported during year.

DIVERSIONS. Considerable water diverted above station for irrigation; amount not 

known. - : .? , t; ,,_ :,% ,-_ ,,: ._ .-.-,.

REGULATION. Available data indicate no regulation abov^f^fciw^ -;. ,t ; ,

ACCURACY. Stage-discharge relation no*- permanent. R|t%g;.cmJ"w well defined 

below 200 second-feet. Gage read to half -tenths twice daily ; ^* heights subject 

to error because of careless observations. Daily discharge ascert^w^d by applying' 

mean gage heights to rating table except during periods for wMd** stage-discharge 

relation was affected by shifting control. Discharge for high iNspe determined 

from extension of rating curve, and may be considerably in error. Results fair.

Backwater from a dam 40 feet high, constructed about 20 mil^-i 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, ar«i returns 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.

Irvin Peoples. ,. . ^ !'.!' ~ .^t .'; J. /

DISCHARGE M^ASUB^^BN*^. Made%waiii^b^wscl*n. l?#fadait"*8 for measurements at medium and high stages.

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

above and below station. Banks wooded, medium in height, and1 not subject to 

overflow. Long concrete dam just below gage serves as a contra1 ; crest of dam 

irregular.

EXTREMES OF DISCHARGE. 1915-16: Maximum stage recorded, 6.50 fret August 22, 

1916 (discharge, 23,000 second-feet; results obtained from extension of rating 

curve and possibly subject to considerable error); no flow during a 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 First 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 of 95.0 and 6.65 secord-feet, respectively.

REGtrLAiTON.^-Flow at station regulated by storage reservoirs and pimping plants 

above.

ACCURACY. Stage-discharge relation practically permanent. Ratinnr 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 hrudredths once 

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

Results poor.

HTTECES HIVER KXAE THBKE BXVXXS, TEX.

LOCATION. At San Antonio, Uvalde-A Gulf Railroad bridge 1 mill west of Kittie, 

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

Frio River.

DRAINAGE ABBA. 15,600 square mike.

'RECORDS AVAILABLE. July 1, 1915, to September 30,1916.

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

DISCHARGE MEASUREMENTS. Made, by wading or from highway bridge half a mile 

below gage.

CHANNEL AND CONTROL. Bed composed of adobe shale; clean; does not change 

greatly. Chamnel straight above and below station. Banks wooded, high, and 

not subject to overflow. Position of high-water control not k^own; shoal just 

below gage probably forms low-water control.

EXTREMES OP DISCHARGE. 1915-16: Maximum stage recorded, 30 feet August 25, 

1916 (discharge, 15,500 second-feet); no flow from March 16 to Jt>ril 5, 1916.

ICE. None reported during year.

DIVEBSIONS. 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 propably small.

ACCURACY. Stage-discharge relation changes slightly. Rating cu~ve well defined 

below 7,000 second-feet. Gage read to half-tenths twice dail"; oftener when 

fluctuations of stage are rapid or extreme. * Daily discharge ascertained by applying gage heights to rating table except during periods for which discharge relation' 

is affected by shifting control.

6§ ,SUBFACE WATER SUPPLY, 1916, PAET VIII. 

NTJECES RIVER AT CALAZJLEH, TEX,

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

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

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

DRAINAGE ABBA. 16,700 square miles.

RECORDS AVAILABLE. August 12,1915, to September 30,1916.

GAGE. Vertical staff attached to pipe-line support of old pump houso; 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. Chanr^l straight above 

and below station. Left bank wooded, low, and bordered by levee constructed 

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

overflow. The breakwater, which is a loose rock fill half a mile below, serves as 

control.

EXTREMES OF DISCHARGE. 1915-16: Maximum stage recorded, 8.38 feet September 

5, 1916 (discharge, §,190 second-feet); minimum stage, 0.65 f^ot March 14 to 

April 6,1916 (discharge, 9.0 second-feet).

ICE. None reported during year.

DIVERSIONS. Considerable water taken from river for irrigation immediately above 

station. The city of Corpus Christi pumps water just below the gage for municipal 

supply and has made a filing with the Board of Water Engineer1 for the State of 

Texas for a continuous use of 0.93 second-foot and a storage of 675 acre-feet per 

annum. The pumping plant is between the breakwater and cab Je and gage, and 

during low stages corrections are made for the amount pumped during currentmeter measurements. A second small pump for private use installed between city 

intake and breakwater is seldom operated. The quantities prmped arte 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 leaJNere through the 

breakwater dam. Rating curve is f airly wefl defined: Gageresdtohundredths 

twice daily. Daily discharge ascertained by applying gage heights to rating table 

except during periods for which stage-discharge relation is affected by shifting 

control. Allowance made for rising and falling stages ia computing discharge. 

Results fair.

FB.IO BIYSK AT FOWTJSBTOH, TEC.

LOCATION. At Frio River dam, about half a mile northeast of Fowlerton, Lasalle 

County, 1| miles below divemon for Frio Lake storage reservois, i miles below 

mouth of Jahuey Greek.

DRAINAGE AREA. 4,350 square miles.

RECORDS AVAILABLE. July 1,1915, to September SO, 1916.

GAGS. Vertical staff attached to tree on right bank about 30 feet above danv read 

by Joe McMains.

DISCHARGE MEASUREMENTS. Made by wading below dam or from railroad bridge 

about a mile above.

GHANNKL 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. Coaerejte dam about 20 feet below gage serves 

as permanent control at all stages. Point of zero flow, gage height 0.05 feet.

EXTREMES OF DISCHARGE. -1915-16; Maximum stage recorded, 3.9 feet at 6 a. m., 

April 19,1916 (discharge, 4,120 second-feet); no flow for extended periods

ICE. None reported during year.

DIVERSIONS . Some -water diverted for irrigation above station. A divera'-m for 

the Frio Lake reservoir is made 1£ miles above; other diversions are scattered; 

amount diverted and areas irrigated not known. A large part of the iHgftted 

land in the 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. Gage read one1* daily 

to hundredths; slight error may be introduced by the assumption that oj*» reading gives the mean stage for the day. Rating curve Well defined belo^ 4,50ft 

second-feet. Daily discharge ascertained by applying the gage heights to rating 

table. Results fair.

Frio Lake is a storage reservoir fed by a diversion from. Frio Riv?r. The 

diversion is made 1J miles above the Frio River dam and the gaging elation on 

the river. The water released from the lake is used for irrigation. Thin station 

is maintained in conjunction with that on Frio River at Fowlerton to show the 

total run-off at that point.

Pole Co.'s bridge, a few hundret^ feet below the Denver & Rio Grand® Paiboad 

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

thfrsoutbeasterm part of Bio Arriba County. Nearest tributary, "Embudo Greek, * 

joins the Rio Graade about 3 miles above station.

DKAINA<JE ASEA. Approximately 10,100 square miles.

EBCORDS AVAiiABLiSi December 21, 1888, to December 31, 1903; September 8,1912, 

to September 30,1916,

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

1889, MI inclined staff gage was maintained 1 mile above Embudo, bu4; it was 

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

March 1, 1889, and used until December 31, 1903; relation of datum of these 

gages unknowB, but the datum remained unchanged from March 1, 1889. to December £tj ;1903. A. Friez water-stage recorder, referred to a new dtttr"n, was 

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

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

was moved to the present site; datum unchanged since station was reestablished 

in 1912.

DISCHARGE MEASCBRMEIWS. Made by wading or from cable just below gago.

CHANNEL AND cosfjibi,. Bed composed of rock, gravel, and sand; shifte at extremely 

high stages. Banks high and not subject to overflow. A shoal just below station serves as a control. '

EXTREMES OF DISCHARGE. ^-Maximum stage during year, from water-stage r-^corder, 

9.9feet at 6 a/m. May 13 (discharge, 16,000 second-feet); minimum stage, 2.28 feet 

at 2 p. m. October 14 (discharge, 393 second-feet).

(discharge, 65 second-feet).

ICE. Stage-discharge relation not seriously affected by ice*

DIVEBSIONS. Considerable water diverted for irrigation above station. Between 

the Colorado-New Mexico State line and Embudo the river flows though a 

canyon and water is diverted for irrigation only in the small areas of bottom 

lands bordering the stream. Above the State line and along the tributaries 

entering the Bio Grande in the canyon large areas of land are irrigated by 

diversions.

REGULATION. The operation of storage reservoirs in Colorado affect the d'^harge 

to slight extent.

ACOTEACY. Stage-discharge relation practically permanent, except for one temporary change; not affected by ice during year. Rating curve well defined ber 

tween 400 and 7,000 second-feet. Operation of water-stage recorder satisfactory. 

Daily discharge ascertained by applying to rating table mean daily gag1* hgigfai

DIVERSIONS, The Carlsbad project of the United States Beclamation Service, with 

reservoirs of a capacity of 58,500 acre-feet, diverts a/ large part, of the jwtT-ml runoff above Carlabad, N. Mex. During the season of irrigation coneiderabl* water is 

returned to the sti^un by seepage from the laMs in the vicinity of Cartel-<d. In 

Itdditibn tx> the- water ased by the Carlsbad project, some diversions are made lor 

irrigation in the basin above the storage reservoirs of the Gattebad prefect.

RBOULATION. The operation of a water-power plant of 300 horsepower capacity above 

station, just below Carlsbad," N. Hex., does not materially regulate Sow at gage. 

The flow is, however, regulated to a large extent by watera stored in tbe ni«»ervoir8 

of the Carlsbad project. In the season of irrigation the effect of the regulation is 

decreased by return seepage waters, but during tike winder the flow depends on 

water released at the reservoirs.

ACCURACY. Stage-discharge relation not permanent. Standard rating curre, used 

lot computing daily discharge by indirect method for shifting control, faMy well 

' d^ned betweea ;140 and 4,500 second-feet. Gage heightjrecord mot continuous 

flue to imperfect operation of recorder. Mean daily gage heights obtained by 

inspecting recorder graph; or, for days of considerable fluctuation, by a">-firaging 

the hourly gage heights. Daily discharge ascertained by indirect method for 

control. Results fair.

 PECOS RIVKR ABOVE BAJISTOW, TEX. - »-r-.v^:=» \-<*,y'

l.oe^isoif. 'rJaee^uarters of a mile below head gate of Biggs irrigatiaa fHfec*, 1 

mile east of Patrole siding on Pecos Valley Railway, 1} miles above h^* gate of 

Barstow Irrigation Co., 14 miles nbrthweit of Barstow, Beeves County, 10 miles 

northwest of Pecos.

DRAINAGE AREA. Not measured.

RECORDS AVAmiU8iji.--rPet>ruary 1, 1916, to September 30,1910.

GA0E. Stevens water-stage recorder on right bank.

DISCHARGE MEASUREMENTS.- Made by wading or from eabfef 156. feet below gage.

CHANNEL AND CONTROL. Channel straight 100 feet above and 300 feet below station. 

Bed composed of gravely clay, and sand; not permanent. Bight bank is clay, 

clean, and fairly permanent; left bank loose sand 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, 

12.1 feet at 6 a. m. August 10 (discharge not determined); minimum stage, 0.88 

foot morning of J»iy 10 (discharge, 36 second-feet).

lea. None reported during year. s

DIVERSIONS. In addition to the 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 First Report of the Board of Water 

Engineers for the State of Texas shows that 26,200 acres were declared irrigated 

above the station, the quantity of water necessary, under an assumed d*-ty of 2 

feet, being 78,600 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.

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

below 700 second-feet and poorly defined above. Mean daily gage heigl *. determined by inspecting the gage-height graph, or, for days of considerable fluctuation, 

by averaging the hourly pge height. Breaks in gage4ieight record caused by 

collections of silt in float box. Daily discharge ascertained by applying mean 

daily gage height to rating table, except from March 26 to May 13, and M^y 22 to 

August 23, when obtained by indirect method for shifting control. Determination 

of discharge during extremely high stages subject to error caused by water flowing over both banks. Results for periods during which water-stage recorder 

operated satisfactorily are good for low and medium stages and fair for big] stages.

DISCHARGE MEA*raais®im.-^IMkki0!by wading 200 feet below^^ageotfrom highway 

bridge. ,

CHANNEL ANJD C&Nraattt,. Bed composed of gravel and rock. Channel straight above 

and below station for 200 feet. Bight bank is rock, medium in height, and subject to overflow faring- esteem© stages; left bank wndy, high, clean and not 

subject to overflow. Shori 200 feet befow-aerves as control for tew and nedium 

stages but is likely to shift; potation of high- water control not known.

EZTOEHBS OF jfflScsASsS'E. Maximum, stage during year, from water-stage r <*order, 

12.8 feet at 8 &. m. August 29 discharge, 4,370 second-feet; result obtained from 

extension of rating curve and possibly considerably in error; minimunr stage, 

0.38 foot 1 a. m. April 17 (discharge not determined).

ICE. None repotted during year.

DIVERSIONS. Statioa i« 3J mites below, diversion of silt-line canal of ImperM Imgatiefi Co., 29 miles below diversion for the Imperial reservoir {capacity 17,000 

acre-feet), 17 miles below diversion for Grandfalla project, and 3 miles above 

diversion for Zimmennan project. Available data show that tracts aggravating 

approximately 143,060 acres are irrigable between station and lower Emits of 

Carlsbad project of United States Bedamation Service. Mrst 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 57,300, the aiflount of water required 

under an aasamed dtffey of 2 acre-feet per acre, being 171,900 acre-feet. The 

effect of diversions is somewhat counterbalanced by water returned to stream by 

seepage.

KEGOTjmoN . None.

ACCURACY. Stage-discharge relation not permanent. Rating curve well c^fined 

below 3,200 second-feet. Gage-height record somewhat fragmentary due to 

-Stoppage of water-stage recorder. Mean daily gage heights obtained by ir<?peeting gage-height graph, or, for days of considerable fluctuation, by use of piani*neter. 

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

except for periods during which stage-discharge relation was affected by shifting

DISCHARGE MEASUEasMBJ?rs.-4ia<ie from cable 1,000 feet above bridge.

CHANNEL AND ooNtROt.^&uaks 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 are not subject to overflow. Stage-discharge relation at the lower stages 

changes slightly.

EXTBBMES or DiseaASSE. Maximum stage recorded during year, 33.0 feet et 10 p. m. 

September 1 (discharge not determined); minimum stage, 0.30 loot fwm 6 p. m. 

June 24 to 6 p, m. lane 25 (discharge, 205 second-feet).

1900-1916: Maximum stage recorded, 35.75 feet April 6, 1900 (dfec^rge not 

determined); mimn»im discharge recorded, 110 second-feet Ifey 13, 14, 1904 

(gage height, Q,$ foot).

ICE, None report^ during year.

DIVERSIONS. Considerable water is diverted and stored above the station for irrigation. I&ke ItcMillan and Lake Avalon, ot 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 

stoeed in New, Mexico, water from Pecos River is used to irrigate larjp 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 diversion'* 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 opemted in the drain^^e basin, 

except a public utility plant of about 300 horsepower, near Carlsbad, N. Mex, 

which does not control the flow at this point.

. Stage-discharge relation subject to slight changes. Gage reai to hundredths twice daily; mean of two readings may not be a true index of zrean daily 

discharge. Hating carve well defined between 200 and 4,<^seeond-fert. D^ily 

dischaige ascertained by applying mean daily gage heights to rating tat *e except 

diiring periods for which the stage-discharge relation is affected by sbiftii ''control.

INTRODUCTION.

Investigation of water resources by the United States 

Survey has consisted in large part of measurements of the vo'unae of 

flow of streams and studies of the conditions affecting that fhw, but 

it has comprised abo investigation of such closely allied subiecip as 

irrigation, water storage, water powers, underground w&te^a, 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, and annual reports, and 

monographs.

The result® 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 eastern Gulf of Mexico basins.

III. Ohio Hirer baan. /

IV. St. Lawrence River basin.

V. Upper Mississippi Eiver and Hudson Bay basins.

VI. Missouri Eiver basin.

VII. Lower Misiaanppi River basin.

VIII. Western Gulf of Mexico basins.

I.. Colorado River basin.

X. Great Basin.

XI. Pacific basins in California. 

XII. North Pacific basins (in three volumes).

HOW GOVERNMENT REPORTS MAY BE OBTAINEI>X OR CONSULTED.

No data regarding stream Bow are given in the 15th and 17th annual reports.

The records at most of the stations discussed in these reports 

extend over aperies of years, and miscellaneous measurements at 

many points other than regular gaging stations hare keen made 

each year. Am index of the reports containing records obtained 

prior to 1904 has been published in Water-Supply Paper 119.

The table below gives, by years and drainage basins, the numbers of the papers on surface-water supply published from 1899 to 

1913. The data for any particular station will in general be found 

in the reports covering tibe years during which the station was maintained. For exaniple, data for Maehias Kiver at WMtoeyvilh, Me., 

1903 to 1913, are published in Water-Supply Papers 57, 124, 165^ 

201, 241, 261, 281, 301, 321, 351, 381, 401, and 431, which contain 

records for the New England streams from 1903 to IMS. P*?sults 

of miscellaneous measurements are published by drainage barms. .

In these papers and in the following lists the stations are arranged 

in downstream order. The main stem of any river is detei'T1dned 

by measuring or estimating its drainage area that is, the headwater 

stream hawing the largest drainage area is considered the cortinuation of the main stream, and local changes in name and lake nirface 

are disregarded* -JU1 stations from the source to the fflouth of the 

main stem of the river are presented first, and the tribi&anes in 

regular order from source to mouth follow, the glflpesto^i^ each 

tributary basin being listed before those of tfee Ba^BlSsffl below.

The exceptions to this rule occur in the records for Mississippi 

Biver, which are givea in four parts, as indicated on page in, and in 

the records for large lakes, where it is simpler to take up the streams, 

in regular order around the rim of the lake than to cross back and 

forth over the lake surface.

GEOLOGIC FOLIOS.

Under the plan adopted for the preparation of a geologic map of the United States 

the entire area is divided into small quadrangles, bounded by certain meridians and 

parallels, and these quadrangles, which number several thousand, are separately 

surveyed and mapped. 1 The unit of survey is also the unit of publication, and the 

maps and description of each quadrangle are issued in the form of a folio. When all 

the folios are completed they will constitute the Geologic Atlas of the United States.

A folio is designated by the name of the principal town or of a prominent natural 

feature within the quadrangle. Each folio includes maps showing the topography, 

geology, underground structure, and mineral deposits of the area mapped and several 

pages of descriptive text. The text explains the maps and describes the topographic 

and geologic features of the country and its mineral products. The topographic map 

shows roads, railroads, waterways, and, by contour lines, the shapes of the bills 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 areas mapped warrant their publication. The folios are of special interest to 

students of geography and geology and are valuable as guides in the development and 

utilization of mineral resources.

The folios numbered from 1 to 163, inclusive, are published in only one form (18 

by 22 inches), called the library edition. Some of the folios that bear numbers higher 

than 163 are published also in an octavo edition (6 by 9 inches). Owing to a fire in 

the Geological Survey building May 18, 1913, the stock of geological folios was more 

or less damaged by fire and water, but 80 or 90 per cent of the folios are usable. They 

will be sold at the uniform price of 5 cents each, with no reduction for wholesale 

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.
