AUTHORIZATION AND SCOPE OF WORK

/

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

measurements of streams in the United States during the years 

ending September 30, 1923.

The data presented in these reports were collected by the United 

States Geological Survey under authority implied in the organic law 

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

Provided, That this officer [the director] shall have the direction of the Geological Survey and the classification of public lands and examination of the 

geological structure, mineral resources, and products of the national domain.

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

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

1895, successive appropriation bills passed by Congress have carried 

the following item:

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.

2 SURFACE WATER SUPPLY, 1923, PAET VIH

Measurements of stream flow have been made at about 4,800 

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

the Hawaiian Islands. In July, 1923, 1,590 gaging stations were 

being maintained by the survey and the cooperating organizations. 

Many miscellaneous discharge measurements were made at other 

points. In connection with this work data were also collected in 

regard to precipitation, evaporation, storage reservoirs, river profiles, 

and water power in many sections of the country and will be made 

available in the 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 work of a certain class. These terms may be divided 

into two groups (1) those that represent a rate of flow, as secondfeet, gallons per minute, miner's inches, and discharge in secondfeet per square mile, and (2) those that represent the actual quantity 

of water, as run-off in 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, and acre-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 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 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 jjjfttjjpn is that point 

on the gage the gage height at which water CfHHfe ^ow over 

control.

EXPLANATION OP

The data presented in this report cover the year 'ending September 

30,1923. At the first 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 by the general methods outlined in standard textbooks on the measurement of river discharge. 

(See Pis. I-III.)

From the discharge measurements rating tables are prepared that 

give the discharge for any stage. The application of the daily gage 

heights to these rating tables gives the daily discharge from which 

the monthly and yearly mean discharge are computed.

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

this report comprise a description of the station, a table giving results of discharge measurements, a table showing the daily discharge, 

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 permanence of the stage-discharge 

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

the stream for log driving, shifting of channel, and the cause and 

effect of backwater. It gives also information as to diversions that 

decrease the flow at the gage, artificial regulation, maximum and 

minimum recorded stages, and the accuracy of the records.
4 SURFACE WATER SUPPLY, 1923, PAET VIII

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

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

stations on streams subject to sudden or rapid diurnal fluctuation 

the discharge^M^fed from the rating table and the mean daily 

gage heights ^ jit be the true mean discharge for the day. If 

such stationsWBpPljjipped with water-stage recorders, the mean 

daily discharge mar 'be obtained by weighting discharge for parts of 

the day or by use of 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 that given in the 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 " 

gives the average flow in cubic feet for each second during the month. 

On this average flow computations recorded in the remaining 

columns which are defined on pages 2 and 3 are based.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

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

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

of observations 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 

stage-discharge relation, (2) precision with which the discharge 

rating curve is defined, (3) refinement of gage readings, (4) fre-. 

quency of gage readings, and (5) methods of applying daily gage 

heights to the rating table to obtain the daily discharge.

For the rating curves " 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 pitting 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 

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

mation concerning water diverted for irrigation or other use, or by
DIVISION OF WOBK 5

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 in inches " are therefore not computed if such errors appear 

probable, and 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 in inches" 

previously published by the Geological Survey should be used withcaution because of possible inherent sources of error not known to 

the survey.

Many gaging stations on streams in the irrigated sections of the 

United States are located above most of the diversions from those 

streams, and the discharge recorded does not show the water supply 

available for further development, as prior appropriations below the 

stations must first be satisfied. To give an idea of the amount of 

prior appropriations, a paragraph on diversions is presented in each 

station description. The figures given can not be considered exact, 

but represent the best information available.

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 records previously published.

LOCATION. In see. 31, T. 6 S., R. 5 W., at Gulf Coast Railroad bridge, threefourths mile below mouth of Whiskey Chitto Creek and 4 miles west of 

Kinder.

DRAINAGE AEEA. 1,760 square miles (measured on post-route map and project 

map of Louisiana Gravity Canal Co., scale 1: 380,000).

RECORDS AVAILABLE. August 23, 1922, to September 30, 1923.

GAGE. Gurley eight-day water-stage recorder attached to downstream side of 

railroad bridge pier; inspected by J. L, Joseph or J. M. Forrest.

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

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

Banks medium in height, composed of sand and clay, heavily wooded, and 

subject to overflow. Several channels at high stages. Bed .composed of 

fine sand; clean; fairly permanent. No well-defined control.

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

recorder, 19.23 feet at 5 p. m. April 14 (discharge, 46,500 second-feet, determined from extension of rating curve and subject to error) ; minimum 

stage, 1.01 feet from 12 to 2 p. m. October 25 (discharge, 370 second-feet). 

1922-1923: Maximum and minimum stages same as given above.

DIVERSIONS. Kinder Canal Co.'s pump diverts water 2 miles upstream and 

above mouth of Whiskey Chitto Creek. About 7,000 acres of rice were 

irrigated in 1922.

REGULATION. Operation of Kinder Canal Co.'s pump affects flow at low stages.

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

defined for all stages. Operation of water-stage recorder satisfactory, 

except as noted in footnote to daily-discharge table. Daily discharge determined by applying to rating table mean daily gage height obtained from 

recorder graph by inspection or by use of planimeter, except as noted in 

footnote to daily discharge table. Records good.

WEST FORK OF TRINITY RIVER AT BRIDGEPORT, TEX.

LOCATION. At suspension bridge on Balsora-Bridgeport road, half a mile 

southwest of center of Bridgeport, Wise County, a quarter of a mile above 

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

below mouth of Gentry Creek.

DBAINAGE AEEA. 1,010 square miles (revised measurement on topographic maps 

and map of Texas, scale 1: 500,000).

RECORDS AVAILABLE, October 1, 1914, to September 30, 1923. Records of stage 

have been obtained by the United States Weather Bureau since August 

12, 1908.

GAGE. Weight and tape gage of the Mott type, on downstream side of bridge; 

read by Eugene Hembree.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge or by 

wading.

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 rock outcrop, 

three-quarters of a mile below station. A low dam was built on the control during the first week in November, 1922.

EXTREMES op DISCHARGE. Maximum stage recorded during year, 25.7 feet at 

6 p. m. April 25 (discharge, 14,700 second-feet, determined frtom extension 

of rating curve and subject to error) ; no flow October 1 to November 11 

and December 9 to January 6.

1908-1923: Maximum stage recorded, 28.9 feet June 8, 1915 (discharge 

not determined) ; no flow during several periods.

DIVERSIONS. Practically the only diversion above station is by city of Bridgeport, which diverts a small amount for municipal uses.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent, except for change caused by 

construction of a low dam below gage during period of no flow in November. Rating curves fairly well defined below 11,000 second-feet and 

extended above that point. Gage read to hundredths once daily, and oftener 

during floods. Daily discharge ascertained by applying mean daily gage 

height to rating table. Records fair.

WEST FORE OF TRINITY RIVER AT FORT WORTH, TEX.

LOCATION. At old intake pump house of the Fort Worth Power & Light Co.'s 

plant, in Fort Worth, Tarrant County, one-fourth mile below mouth of 

Clear Fork of Trinity River and 150 feet above Paddock viaduct.

DRAINAGE AREA. 2,430 square miles (revised measurement on topographic 

maps and map of Texas, scale 1: 500,000).
12 SURFACE WATEE SUPPLY, 1923, PART VIH

RECORDS AVAILABLE. October 11, 1920, to September 30, 1923. Records of 

stage have been kept by United States Weather Bureau at Paddock 

viaduct since March 1, 1910.

GAGE. Gurley graph water-stage recorder, located in the old pump house of 

Fort Worth Power & Light Co.; attended by employee of the city.

DISCHARGE MEASUREMENTS. Made by wading from highway bridge 1,000 feet 

above, or from North Twelfth Street Bridge, 2 miles below gage.

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

below gage. Right bank high, brushy, and not subject to overflow. Left 

bank low, with a protection levee, but subject to overflow at high stages. 

Bed composed of rock, gravel, and clay. Control is a concrete dam just 

below gage and is permanent.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage recorder, 16.25 feet at 11 a. m. June 11 (discharge, 16,300 second-feet); 

minimum stage, 0.87 foot at 11 p. m. August 17 and from 4 to 11 p. m. 

August 22 (discharge, 0.8 second-foot).

1910-1923: Maximum stage recorded, 23.95 feet at 12.20 p. m. April 25, 

1922 (discharge, 85,000 second-feet) ; no flow during several periods.

DIVERSIONS. The city of Fort Worth diverts for municipal use about 15 

second-feet from storage reservoir on West Fork known as Lake Worth.

REGULATION. Flow is partly regulated by storage at Lake Worth, which has 

a capacity of about 30,000 acre-feet.

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

from 0 to 14,000 second-feet and extended above by use of one slope 

measurement at a stage of 23.95 feet (85,000 second-feet). Operation of 

water-stage recorder not satisfactory. Daily discharge ascertained by 

applying to rating table mean daily gage height determined from recorder 

graph by inspection, by use of planimeter, or by averaging discharge for 

fractional parts of a day, except as noted in footnote'to daily-discharge 

table. Records good, except those for low stages which are fair.

TRINITY RIVES AT DALLAS, TEX.

LOCATION. At Commerce Street viaduct in Dallas, Dallas County, 800 feet 

below Texas & Pacific Railroad bridge and 5 miles by river below confluence of Elm and West Forks of Trinity River.

DRAINAGE AREA. 6,000 square miles (revised measurement on topographic 

maps and map of Texas, scale 1:500,000).
14 SUKPA'CE WATER SUPPLY, 1923, PART vin

RECORDS AVAILABLE. October 1, 1898, to December 31, 1899 (discharge not 

computed) ; July 1, 1903, to December 31, 1906; and October 1, 1920, to 

September 30, 1923. Gage readings by United States Weather Bureau 

available since 1903.

GAGE. Chain gage attached to downstream handrail of Commerce Streat viaduct; read by C. J. Anderson.

DISCHAEGE MEAStrEEMENTS. Made by wading, from upstream side of Commerce Street viaduct, or from " Miller's Ferry" bridge, about 6 miles 

downstream from gage.

CHANNEL AND CONTBOL. Channel practically straight for 1,000 feet above and 

600 feet below station. Right bank medium in height, composed of clay 

and gravel, wooded, and subject to overflow. Left bank fairly clean and 

not subject to overflow, except at extremely high stages. Bed is composed 

of clay and gravel and is fairly permanent. Low-water control is a gravel 

and clay shoal about 300 feet below gage. High-water control is not 

known. A lock and dam, 13 miles below gage, will back water at station 

to a gage height of 11.65 feet when wickets are closed. This, however, 

rarely occurs.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3T.45 feet at 

4.45 p. m. June 12 (discharge, 37,900 second-feet) ; minimum discharge, 

8.8 second-feet at 4.50 p. m. November 29.

1898-1899; 1903-1906; 1920-1923: Maximum stage recorded, 42.35 feet 

at 5.15 a. m. April 27, 1922 (discharge, 75,100 second-feet) ; minimum 

discharge, that of November 29, 1922.

Maximum flood on record from United States Weather Bureau records, 

52.6 feet at 6 p. m. May 26, 1908 (discharge not determined). During 

drought of 1917-1918 discharge was practically zero.

DIVERSIONS. Only known diversions are for municipal uses. No irrigation of 

importance above.

REGULATION. Low-water flow is partly regulated by municipal dams on West 

Fork, 40 miles above, and on Elm Fork, 6 miles above gage.

ACCURACY. Stage-discharge relation changed November 20, 1922. Rating 

curves used before and after change well defined from 20 to 75,000 secondfeet. Gage read to hundredths twice daily, except December 15-25 and 

April 19-21, when Weather Bureau gage heights of one reading daily were 

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

rating table. Records good except for extremely low stages, for which 

they are fair.

The following discharge measurements were made by T. A. Slack: 

December 27, 1922: Gage height, 4.86 feet; discharge, 33.6 second-feet. 

August 16, 1923: Gage height, 4.71 feet; discharge, 26.1 second-feet.

16 SUEPACE WATEE SUPPLY, 1923, PAET VIII

ELM FORK OF TRINITY RIVER NEAR DALLAS, TEX.

LOCATION. At city »f Dallas pumping plant and dam (known as Record 

Crossing plant), 300 feet above Record Crossing highway bridge, 2,800 

feet above Rock Island Railway bridge, 1.2 .miles above confluence with 

West Fork, and 5 miles northwest of Dallas, Dallas County.

DRAINAGE AREA. 2,660 square miles (revised measurement on topographic 

maps and map of Texas, scale 1 :500,000).

RECORDS AyATr.ABr.ie. October 17, 1920, to September 30, 1923.

GAGE. Vertical staff in three sections, attached to pump house; read by W. 

J. Selby.

DISCHARGE MEASUREMENTS. Made from Record Crossing highway bridge, 200> 

feet below gage, from Rock Island Railway bridge half a mile below, or 

by wading just below gage.

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

is concrete dam; permanent. Left bank high, wooded, and not subject 

to overflow, except at extremely high stages. Right bank medium inheight, wooded, and subject to overflow.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, -15.05 feet 

at 8 a. m. April 29 (discharge not determined on account of backwater) ; 

a higher stage probably occurred some time in June, when gage was not 

read. No flow during several periods.

1920-1923: Maximum stage recorded, 20.20 feet at 10 a. m. April 27. 

1922 (discharge not determined; backwater from Trinity River existed 

this day, which affected gage height). No flow during several periods,

DIVERSIONS. No diversion except for. municipal use, the largest being at the 

Record Crossing plant. The sum of all the diversions is believed to be 

but a small percentage of the total run-off during years of ordinary flow.

REGULATION. During extremely low stages flow regulated by city of Dallas 

Reservoir at Carrolton.

ACCURACY. Stage-discharge relation permanent, except during periods of backwater. Rating curve well defined below 1,100 second-feet and fairly 

well defined from 6,200 second-feet to 16,000 second-feet. No measurement between 1,100 and 6,200 second-feet, and this portion of the rating 

may be slightly in error. Gage read to hundredths twice daily and oftener 

during floods, except May 13 to July 8, when there were no readings. 

Daily discharge ascertained by applying mean daily gage height to rating 

table. Records fair.

24 SURFACE WATER SUPPLY, 1923, PART VIII

GAGE. Vertical staff on right bank, opposite pumping plant; read by pump 

man.

DISCHARGE MEASUREMENTS. Made by wading or from highway bridge, 500 feet 

below gage.

CHANNEL AND CONTROL. Right bank high and fairly clean; left bank wooded 

and is overflowed during extremely high stages. Control is formed by 

concrete dam about 800 feet below gage.

EXTREMES OF DISCHARGE. Maximum stage during year, 14.10 feet at 6 a. nu 

April 26 (discharge not determined). No flow for long periods.

1921-1923: Maximum stage, 18.25 feet" at 10.30 p. m. April 30, 1922 

(discharge not determined). No flow for several periods each year.

DIVERSIONS. Large part of ordinary flow diverted for municipal use and. 

mining purposes.

REGULATION. Low-water flow partly regulated by dam above gage.

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

defined from 0 to 3,200 second-feet. Gage read to hundredths twice dailyDaily discharge ascertained by applying mean daily gage height to rating 

table, except when stage was beyond limits of rating curve, as noted in 

footnote to daily-discharge table. Records for low and medium stagegood.

No discharge measurements were made during the year.

LITTLE RIVER AT CAMERON, TEX.

LOCATION. At McCowan Bridge at Cameron-Rockdale highway crossing, 1 mile 

above Gulf, Colorado & Santa Fe Railroad bridge, 2 miles southeast of 

Cameron, and 6% miles below mouth of San Gabriel River.

DRAINAGE AEEA. 7,030 square miles (revised measurement on topographic maps, 

map compiled by United States Geological Survey, scale 1:500,000, and 

progressive military map of United States Army).

RECORDS AVAILABLE. November 1, 1916, to September 30, 1923.

OAOE. Chain gage attached to upstream handrail of bridge, installed September

* 30, 1922; prior to that date a vertical and inclined staff attached to trees 

on left bank 200 feet below city pumping plant. Gage read by Tracy Hobson. Relation between gages not known except at a 4-foot stage by new 

gage; old gage reads 2.0 feet less.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNELL AND CONTROL. Bed composed of rock, boulders, sand, gravel, and 

clay; fairly permanent. Right bank, rock, high and overflowed at extremely 

high stages. Left bank, clay and gravel, slightly wooded, and water flows 

through a draw at a stage of 27 feet and over the road at a stage of 31.5 

feet. A rough rock and gravel shoal 20 feet below gage serves as control 

for low and medium stages; may shift. 

Brazos River backwater may reach gage.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 33.2 feet at 

8.35 a. m. April 13 (discharge, 21,500 second-feet, determined by extension 

of rating curve and estimated flow in overflow channel and subject to 

error) ; minimum stage 3.22 feet, August 22 (discharge, 29 second-feet, 

determined from extension of rating curve and subject to error).

1917-1923: Maximum stage recorded, 49.5 feet at 2.30 p. m. September 10, 

1921 (discharge, 647,000 second-feet, determined by slope method, using 

value of Oi035 for " n" in Kutter's formula) ; minimum discharge, 2.6 

second-feet at 7 a. m. September 3, 5, and 7, 1918.

DIVERSIONS. Numerous small diversions are made for irrigation and 

municipal uses, but such diversions have little effect on flow at station, 

except during extremely low stages. Records of the Board of Water Engineers for the State of Texas show that about 2,500 acres have been declared irrigated above station. No diversions of consequence below station. 

During time of low flow water pumped by Cameron Power & Light Co. 

affects flow at this station.

During extremely high stages on
26 SURFACE WATER SUPPLY, 1923, PART VIII

REGULATION. Slight effect by pumping for city.of Cameron.

ACCURACY. Stage-discharge relation permanent, except that extremely high 

stages of Brazos River may cause backwater at this point. Rating curve 

well defined from 150 to 11,500 second-feet; extended below 150 second-feet 

by estimation and above 11,500 second-feet on basis of a slope measurement at gage height 49.5 feet (647,000 second-feet). Gage read to hundredths twice daily. Daily discharge determined by applying mean daily 

gage height to rating table, except as noted in footnote to daily discharge 

.table. Records for medium stages good, and only fair for low and high 

stages.

 stage have heen obtained at Hutchins Avenue gage by the United States 

Weather Bureau since July 1, 1903.

GAGE. Staff gage in five sections on right bank, read by Lennis Brown, installed December 20, 1922, half a mile downstream from chain gage 

previously used at Hutchins Avenue highway bridge. Gage at present 

site read by Lennis Brown; former gage read by A. J. Voelkel. Relation 

between present and former gages not known.

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, gravel, and rock; shifting. Control is rock shoal onethird mile below gage; permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during years, 24.81 feet at 

7 a. m. April 25 (discharge not determined) ; minimum discharge, 0.50 

second-foot August 10-12 and 17-19.

1916-1923: Maximum stage recorded, 26.0 feet during night of April 

26, 1922 (discharge, 28,000 second-feet, determined from extension of 

rating curve and subject to large error). No flow during several periods.

DIVERSIONS. During low stages a large part of flow is diverted a few miles 

above station for irrigation. Records of. the Board of Water Engineers 

for the State of Texas show that about 6,900 acres have been declared 

irrigated above station.
28 SUBFACE WATEE SUPPLY, 1923, PAET VTH

EEGTTLATION. None of consequence.

ACOUEACY. Stage-discharge relation not permanent prior to December 19, when 

station was moved downstream. Rating curve used October 1 to December 

18 is fairly well defined below 16,000 second-feet, and curve used December 19 to September 30 is fairly well defined below 1,000 second-feet and 

poorly defined from 1,000 to 14,000 second-feet. Gage read to hundredths 

twice daily. Daily discharge determined by applying mean daily gage 

height to rating table; shifting-control method used October 29 to December 18. Records poor prior to December 18; records after that date good 

for low and medium stages and poor for high stages.

COLORADO RIVER AT MARBLE FALLS, TEX.

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

Burnet County, and 10 miles below mouth of Sandy Creek.

DRAINAGE AREA. 36,100 square miles (revised measurement on topographic map 

and map compiled by United States Geological Survey, scale 1:500,000).

RECORDS AVAILABLE. October 1, 1916, to September 30, 1923. Miscellaneous 

discharge measurements were made in 1902. Records of stage have been 

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

GAGE. Chain gage on upstream side of bridge. United States Weather Bureau 

weight and1 tape gage on upstream side of bridge was used from October 1, 

1916, to October 5, 1922. Both gages to same datum. Read by M. M. 

Galloway.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

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

gravel, and clay; wooded, and not subject to overflow. Rapids just below 

gage serve as fairly permanent control, except at times when sand and 

gravel collect.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 14.25 feet at 

6.40 a. m. May 5 (discharge not determined) ; minimum stage, 0.59 foot at 

6 a. m. August 20 (discharge, 55 second-feet, subject to error due to 

influence of wind on tape).

1900-1923: Maximum stage,1 23.9 feet April 7, 1900 (discharge not determined). No flow August 7, 8, and 11-25, 1918, caused by storing water 

above gage. x

DIVERSIONS. Several large projects have been proposed in the drainage basin 

above station, but none has been developed. Numerous small' diversions for 

irrigation and municipal uses are made above station. Total amount 

diverted not known. Records of the Board of Water Engineers for the 

State of Texas show that about 36,000 acres have been declared irrigated 

by diversions above station. Little water is diverted between Marble Falls 

and Austin.

REGULATION. None of importance, except possibly during extremely low stages.

1 United States Weather Bureau " Daily River Stages." 

4241 27 WISP 568 3
30 SUBFACE WATER SUPPLY, 1923, PAET VIII

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

from below 6,000 second-feet and poorly defined above, owing to inability 

to read gage accurately on account of surge and inaccuracies in measurements due to high velocities and submerged drift. Gage read to hundredths 

twice daily, though influence of wind on the long gage chain and surge 

of water at high stages probably introduce some error. Daily discharge 

below 6,000 second-feet determined by applying mean daily gage height to 

rating table. Records fair for low stages. Discharge above 6,000 secondfeet as published in previous reports i$ subject to large error and should be 

used with caution.

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

a mile below Snoal Creek and above mouth of Waller Creek, 3% miles 

below Austin dam.

DRAINAGE AREA. 38,200 square miles (revised measurement on topographic 

maps and map compiled by United States Geological Survey, scale 

1:500,000).

RECORDS AVAILABLE. February 15, 1898, to September 30, 1923.

GAGE. Stevens water-stage recorder installed April 26, 1918, used to February 

28, 1923, when an Au recorder installed March 1, 1923, on downstream 

side of pier of viaduct; inspected by engineers from United States Geological Survey.

DISCHARGE MEASUREMENTS. Made by wading or from upstream side of 

Montopolis highway bridge, 4 miles below gage.

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

below gage. Bight bank of medium height, composed of clay and gravel, 

improved by city, and subject to overflow; left bank resembles right bank, 

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

rock, gravel, and sand; shifts. Control is gravel and rock shoal 500 

feet below gage; changes during high water, and also during low water 

because of removal of sand for municipal use.

EXTREMES OF DISCHARGE. Maximum stage from water-stage recorder, 13.04 

feet at 5.30 a. m. May 1 (discharge, 50,200 second-feet) ; minimum discharge, 92 second-feet at 4.15 a. m. August 22.

1898-1923: Maximum stage recorded, 33.5 feet a few minutes after 

failure of dam, which occurred at 11.30 a. m. April 7, 1900 (discharge, 

236,000 second-feet, determined from extension of rating curve and subject 

to considerable error). At time of failure depth of water over crest of 

dam was 11.07 feet, with a computed discharge of 151,000 second-feet. 

According to information obtained from people living near Congress 

Avenue Bridge, water rose 6.1 feet as result of failure of dam. Therefore gage height corresponding to discharge of 151,000 second-feet was 

27.4 feet. According to a statement by Mr. W. P. Johnson, who was in 

charge of power plant at dam, flood appeared to be practically at its crest 

when dam failed. Minimum stage, 0.18 foot at 6 p. m. August 18, 1918 

(discharge, 13 second-feet).

DIVERSION. Records of the Board of Water Engineers for the State of Texas 

show that approximately 36,000 acres of land have been declared irrigated 

by diversions above station. Most of the area irrigated is in the upper 

basin of the main stream and adjacent to large tributaries. Little water is 

diverted between Austin and Columbus.
32 SURFACE WATER SUPPLY, 1923, PART VIII

REGULATION. Flow entirely regulated at times by operation at Austin Dam, 

about 3y2 miles upstream. Neither sluice gates, crest gates, nor power 

plant at dam were in operation during years ending September 30, 1919- 

1923. Capacity of reservoir about 24,000 acre-feet.

ACCURACY. Stage-discharge relation not permanent. Numerous measurements 

made throughout year. Rating curve well defined for all stages. Operation of water-stage recorder satisfactory, except for short breaks in 

record, as noted in footnote to daily discharge table. Daily discharge 

ascertained by applying to rating table mean daily gage height obtained 

from recorder charts by inspection or by use of planimeter, except as 

noted in footnote to daily discharge table; shifting-control method used 

August 31 to September 30. Records good.

34 SURFACE WATER SUPPLY, 1923, PART VIII 

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 

edge of Columbus, Colorado County.

DRAINAGE AREA. 40,800 square miles (revised measurement on topographic 

maps, map compiled by United States Geological Survey, scale 1:500,000, 

and progressive military maps of United States Army).

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

September 30, 1923.

GAGE. Gurley graph water-stage recorder, inspected by J. H. Hastedt or L. 

Hastedt.

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 and is overflowed above a gage height 

of 34 feet. Bed of stream sandy; shifts. A sand and gravel section 350 

feet below gage may serve as low-water control; stage-discharge relation 

during medium and high stages may be controlled by a bend in river 

below bridge.

EXTREMES OF DISCHARGE. Maximum stage during year, estimated from graph 

drawn from Weather Bureau records, 28 feet on the afternoon of May 2 

(discharge, 44,600 second-feet) ; minimum discharge, 260 second-feet December 29 and 30.

1902-1911; 1916-1923: Maximum stage, from water-stage recorder, 38.3 

feet at 3 p. m. May 5, 1922 (discharge, 79,500 second-feet, determined from 

extension of rating curve and subject to error) ; 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 

diverted. Station is above irrigated rice belt, which comprises several 

thousand acres. Records of the Board of Water Engineers for the State 

of Texas show that about 36,000 acres have been declared irrigated above 

Austin.

REGULATION. Flow at Columbus during low stages partly controlled by storage at Lake Austin.

ACCURACY. Stage-discharge relation not permanent. Rating curve used October 1 to April 17 fairly well defined below 65,000 second-feet, and curve 

used April 18 to September 30 well defined from 100 to 65,000 second-feet. 

Operation of water-stage recorder not satisfactory, owing to changes in 

channel. Mean daily gage heights obtained from recorder graph by inspection or by use of planimeter, except October 1 to July 10 and July 

15-17, which were obtained from graph based on one reading1 daily by 

the United States Weather Bureau. Daily discharge ascertained by 

shifting-control method. Records poor.

COOPERATION. Record of gage heights furnished by United States Weather 

Bureau October 1 to July 10 and July 15-17.

36 SUEFACE WATEE SUPPLY, 1923, PART VIII

COLOEADO EIVEE AT WHABTON, TEX.

LOCATION. At highway bridge in western edge of Wharton, Wharton County, 

200 feet below Galvcston, Harrisburg & San Antonio Railway bridge.

DRAINAGE AREA. 41,200 square miles (revised measurement on topographic 

maps, map compiled by United States Geological Survey, scale 1:500,000, 

and progressive military maps of United States Army).

RECORDS AVAILABLE. July 12 to August 31, 1916, July 3 to August 18, 1917, 

July 11 to August 4, 1918, and April 19, 1919, to September 30, 1923.

GAGE. Gurley graph water-stage recorder attached to pier of highway bridge 

near left bank, installed March 19, 1919,

DISCHARGE MEASUREMENTS. Made from highway or railway bridge.

CHANNEL AND CONTROL. Channel straight above and below station for a few 

hundred feet. Bed composed of sand and clay, and subject to shift. 

Banks medium in height, composed of clay, and subject to overflow during 

extremely high stages. At a gage height of 34 feet water enters a channel above station known as Caney Creek and flows thence to Gulf of 

Mexico. The Colorado River raft, several miles below station, probably 

serves as control for all stages.

EXTREMES OP DISCHARGE. Maximum stage, from water-stage recorder, 29.5 

feet at 4 p. m. May 3 (discharge, 29,300 second-feet, determined from extension of rating curve) ; minimum stage, 6.62 feet from 3 to 7 p. m. 

August 25 (discharge, 176 second-feet, ascertained from extension of 

rating curve and subject to error).

1916-1923: Maximum stage recorded during periods of record, 40.7 

feet from 9 a. m. to 6 p. m. May 6, 1922 (discharge not determined) ; 

minimum stage, 4.35 feet at 12.46 p. m. August 27, 1921 (discharge, 45 

second-feet, ascertained from extension of rating curve and subject to 

error).

DIVERSIONS. Station is in area of rice irrigation, roughly estimated to cover 

75,000 acres, about one-third of which is irrigated by diversions from 

Colorado River between Columbus and Wharton, and the remaining 

two-thirds by diversions below Wharton. During periods of maximum 

Remands practically the entire flow is diverted, unless the river is above 

ordinary stage.

REGULATION. Flow at low and medium stages is regulated to some extent 

by storage in Lake Austin at Austin, Tex.

ACCURACY. Stage-discharge relation not permanent. Rating curve fairly welldefined from 500 to 4,000 second-feet, and extended parallel to the old 

curve to cover range of stage. Operation of water-stage recorder satisfactory, except for short breaks in record. Mean daily gage heights 

determined from recorder graph by inspection or by use of planimeter. 

Daily discharge determined by shifting-control method, except as noted 

in footnote to daily discharge table. Stage-discharge relation affected 

by backwater from the "raft." Records fair.

NORTH CONCHO HIVES AT SAN ANGKELO, TEX.

I

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

above confluence of North Concho and South Concho Rivers.

DRAINAGE AREA. 1,800 square miles (revised measurement on topographic maps 

and maps compiled by United States Geological Survey, scale 1:500,000).

RECORDS AVAILABLE. October 27, 1915, to September 30, 1923. 

4241 27- WSP 568 4
38 SUBFACE WATER SUPPLY, 1923, PART VIII

GAGE. Stevens continuous water-stage recorder attached to left side of web 

of third pier of viaduct from left bank, installed September 1, 1920; inspected by B. W. Wynn.

DISCHABQE MEASUREMENTS. Made from second highway bridge upstream from 

gage or by wading.

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

covered in high-water channel with grass and inoss; permanent. Channel 

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

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 4% feet high, which before the viaduct was constructed served as part of low-water crossing. This dam forms an artificial 

control and insures a permanent stage-discharge relation. Backwater 

probably occurs at this station when Concho River reaches a stage of 25 

feet.

EXTBEMES OF DiscHABGE. Maximum stage during year ending September 30, 

1923, from water-stage recorder, 2.55 feet at 11 a. m. April 24 (discharge, 

1,730 second-feet, partly estimated and subject to error). No flow for 

several periods.

1916-1923: Maximum stage from water-stage recorder, 19.3 feet at 7.30 

p. m. April 26, 1922 (discharge not determined; backwater from North 

Concho River probably existed). No flow for several periods during record.

DIVEBSIONS. Records of the Board of Water Engineers for the State of Texas 

show that about 600 acres have been declared irrigated by diversions from* 

North Concho River, all above station.

REGULATION. None of consequence.

ACCURACY. Stage-discharge relation permanent during year ending September 

30, 1923, except from January 16 to May 5, when part of control was 

temporarily removed. Rating curve well defined for all stages. Operation 

of water-stage recorder satisfactory during period that control was intact. 

Daily discharge ascertained by applying to rating table mean daily gage 

height obtained from recorder graph by inspection or by use of a planimeter, or by averaging discharge for fractional parts of a day, except as 

noted in footnote to daily discharge table. Records fair.

Revised records of daily discharge for years ending September 30, 1918-1922, 

and monthly discharge for entire period of record are given in the tables which 

follow. The changes in the records are due principally to a revision of the 

rating curve for high stages.

NOTE. Mean discharge Nov. 17, 1918, to Jan. 10, 1919, estimated because of unreliable gage readings. Braced figures for other periods show estimated mean discharge 

when no gage readings were obtained. Part of dam forming control was removed 

and discharge estimated Jan. 16 to May 5, 1923, on basis of one discharge measurement and several measurements of depth of water passing through opening in dam. 

Discharge also interpolated or estimated for following days: June 20, 21, Nov. 8, 9, 

1919, Jan. 1, 2, Sept. 6-12, 1920, April 13-18, July 9-12, 1922, Aug. 23-28, 1923. No 

flow during periods for which no discharge is given in the years ending Sept. 30, 1918, 

1921, 1922, and 1923.

CONCHO RIVER NEAR SAN ANGELO, TEX.

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

Rivers, 1% miles southeast of San Angelo, Tom Green County.

DBAINAGE AEEA. 4,490 square miles (revised measurement on topographic maps 

and map compiled by United States Geological Survey, scale 1:500,000).

RBOOBDS AVAILABLE. September 17, 1915, to September 30, 1923.
44 SUKFACE WATER SUPPLY, 1923, PART VIII

GAGE. Stevens continuous water-stage recorder, installed August 9, 1917, on 

right bank, 1,500 feet below an old ford; inspected by B. W. Wynn.

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 rocky, wooded, 

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

and gravel, covered with scattered trees, subject to overflow at high 

stages. Rapids just below gage serve as contrbl for medium and low 

stages, but affected by moss; location of control for high stages not known.

EXTBEMES OF DISCHARGE. Maximum stage during year ending September 30, 

1923, from water-stage recorder, 9.6 feet at noon April 23 (discharge, 

5,800 second-feet) ; minimum stage, 0.23 foot at 6 p. m. November 6 (discharge, 0.7 second-foot).

1915-1923: Maximum stage, 36.8 feet, April 26, 1922 (discharge, 139,000 

second-feet, determined from extension of rating curve); no flow November

29. 1921.

DIVERSIONS. Flow at low stage materially affected by diversions above station. 

About a mile above mouth of South Conehp River a storage dam has been 

constructed by the San Angelo Light & Power Co. for waterworks. 

Records of the Board of Water Engineers for the State of Texas show 

that about 11,000 acres have been declared irrigated by water diverted 

above station and about 3,500 acres by diversions below station.

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

effect on flow at station; no regulation of consequence on North Concho 

River.

ACCURACY. Stage-discharge relation permanent during year ending September

30. 1923. Rating curve well defined for all stages. Operation of waterstage recorded not satisfactory, as shown in footnote to daily discharge 

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

gage height obtained from recorder graph by inspection or by means of 

planimeter, or by averaging discharge for fractional parts of a day. 

Records for 1923, fair.

Discharge for certain high-water periods in years ending September 30, 1915- 

19^22, have been revised as result of revision of rating curve on basis of recent 

high-water discharge measurements. The tables of daily discharge which follow give the revised discharge for the periods affected in the years ending 

September 30, 1915-1918, and complete records for 1919-1922.

DIVERSIONS. Records of the Board of Water Engineers for the State of Texas 

show that about 11,000 acres have been declared Irrigated by diversions 

from Concho River, practically all of which are above station. Flow during low stages is materially affected by diversions.

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

San Angelo. An abandoned dam 12 feet in height, 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 station. None of the 

dams appreciably affects the flow by storing water, except during extremely 

low stages.

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

below 6,000 second-feet and poorly denned between 6,000 and 19,000 secondfeet. Operation of water-stage recorder satisfactory, except as noted in 

footnote to daily discharge table. Daily discharge ascertained by applying to rating table mean daily gage height obtained from recorder graph 

by inspection or by use of planimeter; shifting-control method used 

November 17 to December 16. Records good.

Owing to revision of rating curve for high stages, the records of discharge 

for certain periods of high water in the years ending September 30, 1919 and 

1920, have been revised and are given in the tables which follow.

* Mean discharge, May I and 2, estimated 6,000 second-feet.

 Mean discharge, July 3-28, estimated 600 second-feet.

NOTE. Monthly discharge for years ending Sept. 30,1919 and 1920, supersede those published in WaterSupply Paper 503, because of a revision of records for certain high-water periods as shown in table on page 

50. Monthly discharge for years ending Sept. 30, 1921 and 1922, republished without change except that 

the records for certain periods in April, May, and July, 1922, were completed, as shown in the above table-
COLORADO BIVEB BASIN 53

SAN SABA RIVER AT HENARD, TEX.

LOCATION. At steel highway bridge in Menard, Menard County.

DRAINAGE AREA. 1,150 square miles (revised measurement on topographic 

maps and map compiled by United States Geological Survey, scale 

1:500,000).

RECORDS AVAILABLE. September 14, 1915, to September 30, 1923.

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

read by Haskell Howell or Horace Wilson.

DISCHARGE MEASUREMENTS. 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 

somewhat obstructed by reeds and grass. 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. A sand and 

gravel ford just below gage forms a control during low stages; shifts.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 10.10 feet 

at 6.30 p. m. September 5 (discharge, 3,900 second-feet, determined from 

poorly defined curve and subject to error) ; minimum discharge, 0.2 second-foot August 18.

1915-1923: Maximum stage recorded, 13.6 feet at 2.30 a. m. September 

16, 1915 (discharge, 8,610 second-feet, determined from extension of rating 

curve and subject to large error). No flow July 12-14 and 19-31, August 

1-4 and 26-31, 1918.

DIVERSIONS. Considerable land is irrigated with water diverted above sta 

tion. Noyes Canal, on right side of river, which serves a considerable 

area, diverts a short distance above gage. Records of Board of Water 

Engineers for the State of Texas show that about 4,300 acres have been 

declared irrigated by diversions above station and about 7,700 acres by 

diversions below station.

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

largely controlled at low stages during irrigation season by diversion to 

Noyes Canal.

ACCURACY. Stage-discharge relation not permanent. Rating curve well defined below 270 second-feet and poorly defined above, being based on one 

slope measurement at a stage of 12.1 feet with discharge of 6,640 secondfeet, using values of 0.050 and 0.030 for n in Kutter's formula, for two 

parts of the channel. Gage read to hundredths twice daily. Daily discharge determined by shifting-control method. Records fair.

COLOKADO KIVER BASIN 55

SAN SABA EIVEE NEAR SAN SABA, TEX,

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

China Creek, and 2 miles northwest of San Saba, San Saba County, 4 

miles above mouth of Simpson Creek.

DRAINAGE AREA. 3,040 square miles (measured on topographic maps and map 

compiled by United States Geological Survey, scale 1:500,000).

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

1915, to September 30, 1923. Miscellaneous discharge measurements previous to 1904.

GAGE Vertical and inclined staff, on right bank; read by G. M. Pool.

DISCHARGE MEASXTREMENTS. Made by wading or from downstream side of 

bridge.

CHANNEL AND CONTROL. Channel straight for 100 feet above and below station. Bed composed of rock and gravel; shifts. Left bank composed of 

gravel and clay, wooded, 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 shifts.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 29.0 feet during morning of September 17, determined from floodmarks on gage (discharge not determined) ; minimum stage, 1.12 feet at 6.50 p. m. August 

7 (discharge, 11 second-feet).

1904-1906; 1915-1923: Maximum stage recorded, about 37.0 feet April 

26 or 27, 1922, determined from floodmarks on gage (discharge not 

determined). No flow August 9 and 10, 1918.

DIVERSIONS. Considerable water is diverted from stream and tributaries above 

station. There are also diversions below station, but none near station. 

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

capacity of reservoir not known, but probably small. Records of the 

Board of Water Engineers for the State of Texas show that about 9,300 

acres have been declared irrigated by diversions above station and about 

2,700 acres by diversions below station.

REGULATION. None.

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

from 5 to 6,500 second-feet. Gage read to hundredths twice daily. Daily 

discharge determined by applying mean daily gage height to rating table, 

except September 17, when stage was beyond limits of rating curve and 

discharge estimated. Records fair.

COLORADO RIVER BASIN 57

NORTH LLANO RIVER HEAR JUNCTION, TEX.

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

of Bear Creek, 3 miles northwest of Junction, Kimble County, 4 miles 

above confluence of North Llano and South Llano Rivers.

DRAINAGE AREA. 914 square miles (revised measurement on topographic 

maps and map compiled by United States Geological Survey, scale 1:500,- 

000).

RECORDS AVAILABLE. September 14, 1915, to September 30, 1923.

GAGE. Overhanging chain gage on left bank; read by W. M. Keen.

DISCHARGE MEASUREMENTS. Made by wading or from highway bridge, 2% 

miles below station.

CHANNEL AND CONTROL. Bed composed of solid rock. Channel straight above 

and below for 400 feet, with a series of pools and rapids. Left bank not 

subject to overflow. Right bank wooded and subject to overflow during 

high stages. A solid rock ledge having about 2-foot vertical fall at site 

of old dam is a permanent control for medium and low stages, except for 

slight effect from growth of moss during low stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 23 feet about 

midnight April 24 (discharge, 43,100 second-feet, determined from extension of rating curve) ; minimum stage, 1.08 feet from 8 a. m. to 6.45 

p. m. August 16 (discharge, 0.4 second-foot).

1915-1923: Maximum stage recorded, that of April 24, 1923. No flow 

during several periods.

DIVERSIONS. Records of the Board of Water Engineers for the State of Texas 

show that about 1,200 acres have been declared irrigated by diversions 

above the station. During low stages such diversions materially reduce 

flow at station.

REGULATION. No indication that flow at station is regulated.

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

defined below 360 second-feet and extended above on basis of two slope 

measurements at gage heights of 12.9 and 19.03 feet. Gage read to hundredths twice daily, and oftener during floods. Daily discharge determined 

by applying mean daily gage height to rating table; shifting-control method 

used October 1 to November 13. Except for estimated periods, records good 

for low and medium stages and poor for high stages.

Revised records of daily discharge for certain high-water periods in 1915 and

1918. and unpublished records for periods in the years ending September 30,

1919. 1920, and 1922, contained in table on page 58.

NOTE. Monthly discharge for April and June, 1918, supersede the" figures published in Water-Supply 

Paper 478. Discharge for many months in 1915,1918,1919,1920, and 1922 not previously published because 

of lack of definition of rating curve for high stages, as indicated in footnote to table on page 58 giving the 

daily discharge for certain periods in these years. Monthly discharge for the remaining months republished in order to complete the record.
COLORADO RIVER BASIF 61

LLANO RIVER NEAR JUNCTION, TEX.

LOCATION. 100 feet north of Kerrville-Junction road, 3 miles below confluence 

of North Llano and South Llano Rivers, and 3^ miles east of Junction, 

Kimble County.

DRAINAGE AREA. 1,760 square miles (revised measurement on topographic maps 

and map compiled by United States Geological Survey, scale 1: 500,000).

RECOBDS AVAILABLE. September 13, 1915, to September 80, 1923.

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

bank, and inclined staff, reading from 7.0 to 14.7 feet, and a vertical 

staff, reading from 14.6 to 20.3, the two latter gages 100 feet upstream 

from low-water vertical staff; read by Bonnie 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; permanent. Channel 

straight for 700 feet above and 350 feet below gage. Left bank slightly 

wooded and subject to overflow during high water; right bank not subject to overflow. One channel at all stages, except above a stage of 11.3 

feet, when a small part of the flow may follow a slough that leaves the 

river a short distance above gage and enters the main stream below 

gage. Control for low and medium stages is a rock ledge 75 feet below 

gage, having a fall of about 3 feet.

EXTREMES or DISCHARGE. Maximum stage recorded during year, 17.0 feet 

on September 18 (discharge, 35,700 second-feet; see "Accuracy"); minimum stage, 1.50 feet August 15-21 (discharge, 52 second-feet).

1915-1923: Maximum stage recorded, 26.3 feet at 3 a. m. September 16, 

1915 (discharge, 98,800 second-feet, determined from extension of rating 

curve) ; minimum stage, 1.32 feet August 23-28, 1918 (discharge, 13 secondfeet).

DIVERSIONS. Records of the Board of Water Engineers for the State of Texas 

show that about 2,500 acres have been declared irrigated by diversions 

above station and about 1,300 acres below station. Diversions materially 

reduce flow at station during low stages.

REGULATION. Slight regulation for water-power plant on South Llano River 

at Junction.

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

from 24 to 1,700 second-feet, and extended above on basis of one slope 

measurement at a stage of 24.83 feet and discharge of 85,500 second-feet 

on October 29, 1923, using a value of 0.0375 for n in Kutter's formula. 

Gage read to hundredths once daily. One reading dally for medium 

and.high stages may not be true index to discharge owing to rapid fluctuations. Daily discharge ascertained by applying daily gage height to 

rating table. Records good for low stages and poor for high stages.

Revised records of daily discharge for certain high-water periods in 1915, 

1916, and 1918, and unpublished records for periods in the years ending Sep-. 

tember 30, 1919,1920, and 1922, contained in-the table on page 62.

in the years ending Sept. 30, 1919, 1920, and 1&22 not previously published because o* 

lack of definition of rating curve at high stages. Monthly discharge for the remaining 

months from 1915 to 1922 republished in order to complete the record.
GUADALUPB KIVER BASIN 65

BARTON SPRINGS AT AUSTIN, TEX.

LOCATION. Barton Springs issue from channel of Barton Creek, 1,600 feet above 

Austin-Bee Cave highway bridge, half a mile above confluence of Barton 

Creek with Colorado River, half a mile southwest of Austin, Travis County.

RECORDS AVAILABLE. October 1, 1918, to September 30, 1923. Daily records of 

flow of Barton Creek, which closely approximate flow of Barton Springs, as 

the ordinary flow of the creek is from the springs, have been published 

from April 25, 1917, to September 30, 1918. Miscellaneous discharge measurements of Barton Creek made from 1894 to 1906, and during 1916 and

GUADALUPE RIVER BASIN 

GUADALUPE RIVER NEAR COMFORT, TEX.

LOCATION. On Comfort-Kerrville road, 100 feet upstream from Boerner 

Crossing and 3 miles west of Comfort, Kerr County.

DRAINAGE AREA. 916 square miles (revised measurement on topographic maps, 

progressive military maps of United States Army, and map compiled by 

United States Geological Survey, scale 1:500,000),

RECORDS AVAILABLE. December 16, 1917, to September 30, 1923.

GAGE. Vertical staff in two sections on left bank; read by Robert W. Faust.

DISCHARGE MEASUREMENTS. Low-water measurements made by wading. No 

suitable section available for high-water measurements.

CHANNEL AND CONTROL. Bed composed of rock, sand, and gravel. Left bank 

composed of clay, slightly wooded, and subject to overflow at high stage. 

Right bank low, wooded, and subject to overflow at medium stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 17.2 feet at 

5.30 p. m. September 18 (discharge not determined) ; minimum discharge, 6.2 second-feet August 20.

1917-1923: Maximum stage about 41 feet on August 21, 1919, determined from floodmarks near gage (discharge not determined) ; minimum stage 0.80 foot August 2, 1918 (discharge 0.4 second-foot, probably 

due to diversions above gage).

DIVERSIONS. Few pumping plants along stream about 7 miles above station. 

Records of the Board of Water Engineers for State of Texas show that 

a total of about 400 acres has been declared irrigated by diversions above 

station.
66 SURFACE WATER SUPPLY, 1923, PART VIII

REGULATION. At Kerrville and Center Point dams are constructed and 

water used for mill purposes, but effect of regulation is slight, except 

during low stages.

ACCURACY. Stage-discharge relation not permanent Rating curve well defined below 400 second-feet, and extended above that point on basis of 

one slope measurement at a stage of 8.5 feet, discharge 3,120 second-feet, 

using a value of 0.040 for n in Kutter's formula. Gage read to hundredths 

once daily except Sundays. One reading a day may not be a true index to 

daily discharge at low stages, owing to storage and intermittent pumping, and at high stages, owing to rapid fluctuations. Daily discharge 

ascertained by shifting-control method October 1 to December 1 and 

July 24 to August 31, and by applying mean daily gage height to rating table for remainder of year. Records poor.

GUADALUPE RIVER NEAR SPRING- BRANCH, TEX.

LOCATION. At New Braunfels-Blanco City highway bridge, known as Esser 

Bridge, 4 miles below Spring Branch, Comal County, 6 miles below mouth 

of Curry Creek, and 22 miles by road above New Braunfels.

DRAINAGE AREA. 1,430 square miles (measured on topographic maps, map compiled by United States Geological Survey, scale 1:500,000, and progressive 

military map of United States Army).

RECORDS AVAILABLE. June 28, 1922, to September 30, 1923.

GAGE. Stevens continuous water-stage recorder, attached to downstream side 

of pier on right bank; attended by E. L. Jonas.

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

bridge.

CHANNEL AND CONTROL. Channel straight for 200 feet above and 700 feet 

below gage. Bed composed of solid rock and gravel; permanent. Right 

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

clay'and gravel, covered with grass and brush, and subject to overflow 

at a stage of about 46 feet. Low-water control is a rock and gravel riffle 

350 feet below gage, and is probably permanent.

EXTREMES OF DISCHARGE. Maximum stage from water-stage recorder, 19.75 

feet at 6.40 p. m. September 19 (discharge, 18,200 second-feet) ; minimum 

stage, 1.74 feet during period of missing record, August 18 (discharge, 

4.7 second-feet).

DIVERSIONS. None.

REGULATIONS. None.

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

below 1,000 second-feet, and fairly well defined from 1,000 to 18,000 

second-feet. Operation of water-stage recorder satisfactory, except for 

short breaks in record. Daily discharge determined by applying to rating 

table mean daily gage height ascertained from recorder graph by inspection or by use of planimeter, or by averaging discharge for fractional 

parts of a day. Records fair.

1898-99; 1915-1923: Maximum stage recorded, 28.6 feet at 3 a. m. 

September 10, 1921 (discharge, 56,600 second-feet, determined from extension of rating curve and subject to error). No flow for two hours on each 

of several days in August and September, 1922, and for three hours on 

October 10, 1923, owing to regulation at dam under construction 300 feet 

above gage.

DIVERSION. 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 entirely regulated at times by operation of 

power plants on Comal River and by plant 300 feet above.

4241 27 WSP 568 6
70 SUEFACE WATER SUPPLY, 1923, PART VIII

ACCTIRACY. Stage-discharge relation not permanent, owing to dredging operations on the channel. Rating curve well defined for all stages. Operation 

of water-stage recorder satisfactory, except for short breaks in record. 

Mean daily gage heights determined from recorder graph by inspection or 

by use of planimeter. Daily discharge determined by shifting-control 

method; for days of large range in stage, discharge averaged for intervals 

of a day. Records good.

GUADALTJPE RIVER BELOW CUERO, TEX.

LOCATION. Three-fourths mile upstream from Heards Bridge on Arneckville road and 2% miles southeast of Cuero, Dewitt County.

DRAINAGE AREA. 5,070 square miles (revised measurement on topographic maps, 

map compiled by United States Geological Survey, scale 1:500,000, and 

progressive military maps of United States Army).

RECORDS AVAILABLE. August 6, 1916, to September 30, 1923. (Fragmentary 

from May 29, 1919, to August 10, 1920.) From December 26, 1902, to 

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

was maintained at Schleicher's Bridge, 4 miles above this point. Discharge at two sites practically same.

GAGE. Stevens water-stage recorder on left bank; inspected by E. B. Dietze.

DISCHARGE MEASUREMENTS. Made from cable 40 feet upstream from gage, 

from Schleicher highway bridge 4 miles upstream, from San Antonio 

& Aransas Pass Railway bridge 6 miles upstream, or by wading.

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

feet. Bed composed of gravel and small rock; shifts slightly. Left 

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

and is overflowed at stages above a gage height of 20 feet, the water 

submerging an area for 1 mile back from river. Right bank composed 

of sand and dirt, covered with brush and trees on sloping side and 

cultivated land on top, high, and not subject to overflow. Rock and 

gravel rapid 250 feet below gage serves as a control during low and medium 

stages; shifts slightly.

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

recorder, 13.45 feet at 5 p. m. March 3 (discharge, 9,980 second-feet) ; 

minimum stage, 0.75 foot at 8 a. m. September 4 (discharge, 170 secondfeet).

1916-1923: Maximum stage occurred about October 20, 1919, when recorder was not in operation, and reached a height of about 32.2 feet, 

as determined from floodmarks on gage house (discharge not determined) ; 

minimum stage from water-stage recorder, approximately 0.58 foot from 

9 to 10 a. m. November 1, 1917 (discharge, 80 second-feet, determined 

from extension of rating curve and possibly slightly in error).
72 SURFACE WATEE SUPPLY, 1923, PART VIII

DIVERSIONS. There are numerous small diversions above station for irrigation and municipal uses, but flow is probably not materially affected thereby, except possibly during extremely low stages.

REGULATION. Flow partly regulated during low and medium stages by operation of water-power plants upstream, chiefly by a plant about 8 miles 

above.

ACCURACY. Stage-discharge relation for the year permanent. Curve well 

defined from 200 to 15,000 second-feet and fairly well defined to 36,000 

second-feet. Operation of water-stage recorder satisfactory, except for 

breaks in the record, as noted in footnote to daily discharge table. Daily 

discharge ascertained by applying to rating table mean daily gage height 

obtained from recorder graph by inspection or by use of planimeter, or by 

averaging discharge for fractional parts of a day. Records good.

8 a. m. February 22 (discharge, 16,700 second-feet, determined from extension of rating curve and subject to slight error). No flow at 6.30 p. m. 

July 29.

1915-1923: Maximum stage recorded, 37.5 feet at 7.30 a. m. May 

16, 1920 (discharge not determined) ; minimum stage that of July 29, 

1923.

DIVERSIONS. Small amounts of water are diverted above station for irrigation 

and municipal uses, but only a small part of total run-off is used. Little 

water, if any, is diverted below station.

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

above station. 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. Stagfr-discharge relation not permanent. Rating curve well defined 

from 70 to 15,000 second-feet, and extended beyond these limits to cover 

range in stage for year. Gage read to hundredths twice daily, but mean 

of two readings daily may not be true index to discharge owing to regulation. Daily discharge ascertained by shifting-control method. Records 

fair.

GUADALUPE RIVER BASIN 75

SAN ANTONIO KIVEE. AT SAN ANTONIO, TEX.

LOCATION. At South Alamo Street Bridge in San Antonio, Bexar County, 4 

miles below San Antonio Springs, source of normal flow of river, and iy^ 

miles above mouth of San Pedro Creek.

DRAINAGE ASEA. Indeterminate.

RECORDS AVAILABLE. January 26, 1915, to September 30, 1923. Miscellaneous 

discharge measurements were made from 1895 to 1906.

GAGE. Gurley graph water-stage recorder on right bank at downstream side 

of bridge.

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

CHANNEL AND CONTROL. Channel is straight for 100 feet below gage and 

curved above. Bed composed of sand, gravel, and silt. Control formed 

by gravel bar; shifts.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage recorder, 3.22 feet at 8 a. m. July 21 (discharge, 390 second-feet) ; minimum 

stage, caused by power regulation, 0.97 foot at 10.30 a. m. August 19 

(discharge not determined).

1914-1923: Maximum stage recorded, 20.14 feet about 3 a. m. September 10, 1921, determined from floodmarks on gage (discharge, 

15,300 second-feet, determined by slope method, using value of 0.035 and 

0.050 for n in Kutter's formula) ; minimum stage, 0.58 foot on several 

days during November and December, 1918 (discharge, 7.0 second-feet).

DIVERSIONS. Quantity of water diverted above gage not known, but is probably small. Considerable land is irrigated from diversions below gage.

REGULATION. Operation of water wheels at the Guenther flour mill, just above 

gage, causes sharp fluctuations in stage.

ACCURACT. Stage-discharge relation not permanent. Two well-defined rating 

curves used during year, one applicable October 1 to March 2, the other 

one from March 3 to September 30. Operation of water-stage recorder not 

satisfactory for a few periods noted in footnote td daily-discharge table. 

Daily discharge ascertained by applying to rating table mean daily gage 

height obtained from recorder graph by inspection or by use of planimeter; 

shifting-control method used February 1 to April 30. Records fair.

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

but two tributaries from north furnish considerable run-off at times of heavy 

precipitation. Changes in mean daily 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 probably wells draw 

from underground reservoir that feeds river by .springs.

GUADALUPE EIVEB BASIN 77

SAN ANTONIO BIVEB AT CALAVERAS, TEX.

LOCATION. One-fourth mile south of San Antonio & Aransas Pass Railway 

station in Calaveras, Wilson County, 1 mile below mouth of Calaveras 

Creek.

DRAINAGE ABEA. 1,780 square miles (revised measurement on topographic 

maps, progressive military maps of United States Army, and map of 

Texas, scale 1:500,000),

RECOBDS AVAILABLE. March 12, 1918, to September 30, 1923.

GAGE. Vertical staff in five sections on left bank near old brick plant; read 

by I. M. Smith.

DISCHARGE MEASUREMENTS. Made from highway bridge, half a mile upstream 

from gage, or by wading.

CHANNEL AND CONTROL. Bed composed of sand and clay; shifts. Channel 

straight above and below station for 150 feet. Left bank wooded and not 

subject to overflow; right bank steep, wooded, and subject to overflow only 

at extremely high stages. Old bricks piled into channel form a semipermanent low-water control.

EXTBEMES OF DISCHARGE. Maximum stage recorded during year, 16.55, feet 

at 5.10 p. m. September 7 (discharge, 2,340 second-feet) ; minimum discharge, 48 second-feet August 31, September 1 and 2.

1918-1923: Maximum stage recorded, 42.0 feet at 4 a. m. September li, 

1921| (discharge not determined) ; minimum discharge, 15 second-feet at 

8.30 a. m. September 14, 1918.

DIVERSIONS. The Medina Dam and Reservoir, with a storage capacity of 254,000 

acre-feet, is on Medina River about 50 miles above its confluence with the 

San Antonio. Four miles below Medina Dam are the diversion works, with 

a capacity of 850 second-feet. There were probably about 5,000 acres 

under irrigation in this project in 1922.

REGULATION. The ordinary flow may be slightly affected by storage and 

diversions on Medina River.

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

between 30 and 1,500 second-feet, and extended above by means of the 

AJd method based on a measurement at a discharge of 11,000 secondfeet and subject to error. Gage read to hundredths twice daily, but mean 

of two readings a day may not be a true index to discharge, owing to rapid 

fluctuations. Daily discharge ascertained >by shifting-control method. 

Records fair for low and medium stages and poor for high stages.

SAN PEDBO CREEK AT SAN ANTONIO, TEX.

79

LOCATION. At south end of Missouri, Kansas & Texas Railway culvert, 50 feet 

west of tracks, 700 feet south of its terminal, 200 feet south of Arsenal 

Street crossing, 1 mile above mouth of galsamora and Martinez Creeks, 

2 miles below San Pedro Springs, its source, and 2% miles above confluence 

with San Antonio River.

DRAINAGE AEEA. Indeterminate.

RECORDS AVAILABLE. July 20, 1916, to September 30, 1923.

GAGE. Gurley seven-day water-stage recorder installed March 14, 1921; 

attended by engineers of city of San Antonio.

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

CHANNEL AND CONTROL. Bed and banks composed of smooth concrete; permanent. Low-stage control is a 4 by 4 inch timber bolted across bed of flume.

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

recorder, 3.55 feet at 8.20 a. m. August 28 (discharge, 404 second-feet) ; 

minimum stage, 0.35 foot at 6.40 p. m. March 23 (discharge, 1.9 second-feet). 

1916-1923: Maximum stage recorded, 8.6 feet at 11.30 p. m. September 

9, 1921, when backwater from Alizan Creek existed (discharge not determined) ; minimum stage, 1.30 feet December 10-11, 1918 (discharge, 

0.7 second-foot).

ICE. None reported.

DIVERSION s. None.

REGULATION. Flow partly regulated by small dam at swimming pool in San 

Pedro Park, a few miles above.

ACCURACY. Stage-discharge relation permanent. Bating curve well defined 

from 7 to 11 second-feet and poorly defined from 11 to 200 second-feet, 

and extended above by use of Kutter's formula with a value of 0.014 for n 

at gage height 6.0 feet. Daily discharge ascertained by applying to rating 

table mean daily gage height obtained from recorder graph by inspection 

or by use of planimeter, except as noted in footnote to daily discharge 

table. Records good.

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.

GUADALUPE RIVER BASIN

MEDINA RIVEE NEAB PIPE CEEEK, TEX.

81

LOCATION. 2 miles below mouth of Privilege Creek, 2 miles above backwater 

from, Medina Dam, 3% miles above mouth of Pipe Creek, 4 miles southwest of Pipe Creek post office, Bandera County, and 8 miles east of 

Bandera.

DRAINAGE AEEA. 412 square miles (measured on progressive military map of 

United States Army).

RECORDS AVAILABLE. December 6, 1922, to September 30, 1923.

GAGE. Stevens eight-day water-stage recorder on left bank; inspected by R. E. 

Buck.

DISCHARGE MEASUREMENTS. Made by wading.

CHANNEL AND CONTROL. Bed of stream consists of rock and gravel and some 

moss. Channel is straight for 1,000 feet above and below gage. Bight 

bank rocky, and not subject to overflow. Left bank has gentle incline, 

is sparsely covered with small trees, and begins to be overflowed at 

gage height of 9 feet. Low-water control is a concrete weir 100 feet below 

gage. Weir is about 1.5 feet high for a distance of 95 feet, with abutments 

4 feet higher than crest. A rock riffle 600 feet below gage serves as control during medium stages.

EXTREMES OF DISCHARGE. Maximum stage during period of record from waterstage recorder, 15.36 feet at 1 p. m. April 25 (discharge not determined) ; 

minimum stage, 0.62 foot August 27-29 and September 4 (discharge, 5.4 

second-feet).

DIVERSIONS. None above. Medina Dam and Reservoir, with storage capacity 

of 254,000 acre-feet, is 19 miles below gage. Diversion works have a capacity of 850 second-feet, but only a small per cent of this capacity was 

used in 1923.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent. Hating curve fairly well 

defined below 300 second-feet, and extended above to cover mean daily 

stage during year by means of the formula Q=Clh! with a value for 

C derived from current-meter measurements made at the station. Operation of water-stage recorder satisfactory, except for short breaks in the 

record. Daily discharge determined by applying to rating table mean 

daily gage height obtained from recorder graph by inspection or by use 

of planimeter. Records for low stages good and poor for high stages.

GUABALUPE EIVEE BASIN

MEDINA RIVER NEAR RIOMEDINA, TEX.

83

LOCATION. Just above Medina Valley Irrigation Co.'s diversion dam, 1 mile 

above Haby's crossing, 4 miles below company's main dam, 6 miles northwest of Riomedina, Medina County.

BRAIN AGE AREA. 606 square miles (measured on progressive military map of 

United States Army).

RECORDS AVAILABLE. January 21, 1922, to September 30, 1923.

GAGE. Gurley graph water-stage recorder attached to right upstream side of 

diversion dam; attended by J. B. Milam.

DISCHARGE MEASUREMENTS. Made from cable 2,000 feet below gage, or by 

wading near Haby's crossing 1 mile below gage.

CHANNEL AND CONTROL. Channel composed of rock and gravel; permanent. 

Banks high and not subject to overflow. Control is concrete spillway of 

dam; permanent. Point of zero flow over dam is gage height 0.60 foot.

EXTREMES OF DISCHARGE. No flow over dam during year.

1922-23: Maximum stage from water-stage recorder, 0.74 foot from 4 

p. m. May 5 to 11 p. m. May 6, 1922 (discharge, 28 second-feet, determined 

by subtracting seepage past dam from a measurement made 1 mile below 

dam). No flow over dam, except May 4 to 12, 1922.

DIVERSIONS. Water is diverted to Medina Canal just above gage. About 5,000 

acres irrigated in 1922. Maximum capacity of canal, 850 second-feet. See 

" Medina Canal near Riomedina."

REGULATION. Flow regulated by main storage dam, 4 miles upstream, except 

when main reservoir is full and water flows over spillway.

ACCURACY. Stage-discharge relation permanent. No flow over dam this year. 

A seepage curve, giving relation between height of water behind dam and 

seepage past dam measured 1 mile below, is fairly well defined for all lake 

levels this year. Mean monthly seepage past dam determined by applying to 

seepage rating table mean monthly lake levels obtained by averaging daily 

gage readings. Records fair.

COOPERATION. Daily gage readings of lake level furnished by Medina Valley 

Irrigation Co.

MEDINA CANAL NEAR RIOMEDINA, TEX.

LOCATION. Just above upper end of flume No. 1 on Medina Valley Irrigation 

Co.'s main canal, one-third mile below head of canal and 6 miles north of 

Riomedina, Medina County.

RECORDS AVAILABLE. March 30, 1922, to September 30, 1923. Station maintained during irrigation seasons of 1920 and 1921 by United States Department of Agriculture in cooperation with Texas Board of Water Engineers for seepage studies.

GAGE. Gurley graph water-stage recorder, with inside and outside staff gages.

DISCHAEGE MEASUREMENTS. Made by wading or from foot plank just above 

gage.

CHANNEL AND CONTROL. Metal flume and concrete-lined canal; permanent.

EXTREMES OF DISCHARGE. Maximum stage from water-stage recorder, 2.07 feet 

from 8 a. m. to noon June 26 (discharge, 128 second-feet). No flow during several periods.

1922-23: Maximum stage, that of June 26, 1923. No flow for several 

periods.

DIVERSIONS. Above all diversions from canal.

REGULATION. Flow controlled by head gates. Canal ordinarily carries a small 

flow during nonirrigation season for domestic and stock water uses.

ACCURACY. Stage-discharge relation permanent. Rating curves fairly well defined. Operation of water-stage recorder satisfactory. Daily discharge 

ascertained by applying to rating table mean daily gage height determined from recorder graph by inspection or by use of planimeter, except 

as noted in footnote to daily discharge table. Records good.

Canal diverts from right bank of Medina River, 

near Lacoste and Natalia.

NUECES RIVER BASIN 

NTJECES RIVER NEAR CINONIA, TEX.

LOCATION. Just below suspension bridge, near Oswald ranch, 2 miles east 

of Cinonia, Zavalla County, and 8' miles northeast of Crystal City.

DRAINAGE AEEA. 2,150 square miles (revised measurement on topographic maps, 

progressive military maps of United States Army, and map of Texas, scale 

1:500,000).

RECORDS AVAILABLE. July 5, 1915, to September 30, 1923.

GAGE. Vertical staff in six sections, installed May 6, 1918, on right bank, 200 

feet below highway bridge; read by C. C. Oswald.

DISCHABGE MEASUREMENTS. Made from downstream side of bridge or by 

wading.

CHANNEL AND CONTROL. Bed composed of clay and gravel. Banks wooded; 

not subject to overflow, except at extremely high stages. Channel 

straight above and below station. A concrete control was completed at 

site of gage on September 23, 1917; point of zero flow, gage height 0.85 

foot.

EXTREMES OF DISCHARGE. Maximum stage during year, by leveling to floodmarks, 48.2 feet on September 19 (discharge not determined) ; minimum 

stage, 0.95 foot September 3 (discharge, 0.3 second-foot).

1915-1923: Maximum stage recorded, 49.1 feet September 23, 1919, 

determined by leveling from floodmarks (discharge not determined). 

According to residents, the greatest flood on record occurred in 1913, 

when river reached a stage of about 53.2 feet by present gage datum. 

No flow during several periods of record.
NTJECES RIVER BASIN 87

DIVERSIONS. Considerable water diverted above station for irrigation; amount 

not known.

REGULATION. None.

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

below 700 second-feet and extended above by means of area-velocity curves, 

but does not cover range of stage during year. Gage read to hundredths 

twice daily. Daily discharge determined by applying mean daily gage 

height to rating table, except as noted in footnote to daily discharge table. 

Records for low and medium stages good and for high stages poor.

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 flow of river 

is known to seep into bed just below Uvalde and return to surface just above 

station. Condition of underground water may have an effect on this return 

water and thus help to equalize flow.

The following discharge measurement was made by C. B. Ellsworth: 

July 20, 1923: Gage height, 1.10 feet; discharge, 2.5 second-feet.

NUECES RIVER NEAR THREE RIVERS, TEX.

LOCATION. At San Antonio, Uvalde & Gulf Railroad bridge, 1 mile west of 

Kittie, 2 miles southeast of Three Rivers, Live Oak County, and half a 

mile below inouth of Frio River.

DRAINAGE ABBA. 15,600 square miles (measured on topographic maps, progressive military maps of United States Army, and maps of Texas, scale 

1:500,000).

RECORDS AVAILABLE. July 1, 1915, to September 30, 1923.

GAGE. Vertical staff in four'sections, attached to piers of railroad bridge; 

read by M. L. Mouser or Eldon Gullett.

DISCHARGE MEASURMENTS. Made by wading or from highway bridge half a 

mile below gage.

CHANNEL AND CONTROL. Bed composed of adobe shale and sand; does not 

change greatly. Channel straight above and below station. Banks wooded 

and not subject to overflow, except at extremely high stages. Location of 

high-water control not known; shoal just below gage probably forms lowwater control; shifts.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 41.6 feet 

February 24 (discharge, 16,400 second-feet, determined from extension of 

rating curve and subject to large error) ; minimum discharge, 0.1 second- 

' foot August 27.

1915-1923: Maximum stage recorded, 46.0 feet at 5 a. in. September 18, 

1919 (discharge not determined; probably backwater caused by Gulf 

storm). No flow during several periods of record.

DIVERSIONS. Records for the Board of Water Engineers for the State of Texas 

show that about 10,000 acres have been declared irrigated by diversions 

from stream above station.

REGULATION. None of consequence.

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

defined below 7,000 second-feet and extended above by use of area-velocity 

curves and subject to error. Gage read to nearest tenth or half-tenth once 

daily, and oftener during floods. Daily discharge determined by shiftingcontrol method. Records fair for low and medium stages and poor for 

high stages.

90 SURFACE WATER SUPPLY, 1923, PART VIII 

NUECES 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, half a mile 

above edge of tidewater and breakwater dam.

DRAINAGE AREA. 16,900 square miles (revised measurement on topographic 

maps, progressive military maps of United States Army, and map of Texas, 

scale, 1:500,000).

RECORDS AVAILABLE. August 2, 1915, to September 30, 1923.

GAGE. Vertical staff attached to pipe-line support of old pump house; read by 

John W. Cunningham.

DISCHARGE MEASUREMENTS. Made by wading at backwater 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. Breakwater dam, which is a loose rock fill 

half a mile below, serves as control. It leaks badly and is subject to change 

during floods. Flood damage is repaired by dumping loose rock on crest.

EXTREMES OF STAGE. Maximum stage recorded, 10.90 feet from 4 p. m. February 27 to 8 a. m. February 28; minimum stage, 1.15 feet 4 p. m. August 4, 

and 4 p. m. August 25 to 8 a. m. August 28.

1915-1923: During September, 1919, the river reached a stage of about 

12 feet, as determined from floodmarks on gage. This was not only the 

highest stage reached during period covered by records, but probably 

exceeds any that occurred for many years prior to the establishment of 

this station. Discharge indeterminate, because of lowlands on left bank 

overflowing for a width of several miles. No flow August 23-28, 1918.

DIVERSIONS. Considerable water taken from river for irrigation immediately 

above station, and river water is also used for irrigation throughout drainage above. City of Corpus Christi pumps water just below gage for 

municipal supply. They reported a consumption of 922 acre-feet during 

1918.

REGULATION. None of consequence.

ACCURACY. Stage-discharge relation not permanent, because of leakage through 

and repair to breakwater dam. Rating curve poorly defined. Gage read 

to hundredths twice daily. Daily discharge not computed, because of 

changing control and insufficient discharge measurements. Records poor.

No discharge measurements have been made at this station since 1919.

FRIO RIVER NEAR DERBY, TEX.

LOCATION. At International & Great Northern Hallway bridge, 900 feet below 

mouth of Leona River, 400 feet below highway bridge, 4 miles south of 

Derby, Frio County.

DEAINAGE AEEA. 3,490 square miles (revised measurement on topographic maps, 

progressive military map of United States Army, and map of Texas, scale 

1:500,000).

RECORDS AVAILABLE. August 1, 1915, to September 30, 1923.

GAGE. Vertical staff attached to railway bridge pier; read by C. B. Harris.

DISCHARGE MEASUREMENTS. Made from railway bridge, highway bridge, or by 

wading.

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

curved above and below station, but straight at gage for 150 feet. Banks 

wooded, high, and subject to overflow at extremely high stages. A concrete dam 50 feet below gage serves as control during low and medium 

stages; location of high-water control not known. Point of zero flow, gage 

height 0.07 foot, except when affected by moss on control.
92 SURFACE WATER SUPPLY, 1923, PART VIII

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 9.0 feet froir 

9 p. m. to midnight September 20 (discharge, 5,600 second-feet). No flo\r 

for several periods.

1915-1923: Maximum stage recorded, 18.5 feet September 18, 1919 (discharge, 34,400 second-feet). No flow during several periods of each year.

DIVERSIONS. Small areas are irrigated by diversions in headwaters, but available information does not show that water is taken from stream immediately above station.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent during year ending September 

30, 1923. Bating curve well defined for all stages. Gage read twice daily 

to hundredths. Daily discharge determined by applying mean daily gage 

height to rating table. Records good.

Owing to revision of rating curve for high stages, the records for the 

years ending September 30, 1915, 1916, and 1918-1922, have been revised 

and are published in the tables which follow.

September 9; minimum mean daily discharge, 1,393 second-feet June 22 

and 23.

1900-1914, 1922-23: Maximum stage recorded, 25.75 feet September 16, 

1904 (discharge, 96,900 second-feet, determined from poorly denned rating curve and subject to considerable error) ; minimum mean daily discharge 810 second-feet March 28 and 29, 1912.

On June 22, 1922, a stage of 32.4 feet, present gage datum, was reached 

(from levels by the International Boundary Commission, Mexican Section) 

and the discharge, as determined by United States Geological Survey engineers by the slope method, was 240,000 second-feet.

DIVERSIONS. Considerable water diverted in Colorado, New Mexico, Texas, and 

Mexico ; amount not known.

REGULATION. Flow partly regulated by storage at Elephant Butte Darn, 120 

miles above El Paso. Slight storage on Pecos and Mexican tributaries.

LOCATION. Opposite Matamoros, Tamaulipas, Mexico; half a mile above international railroad bridge and 1 mile above Brownsville, Cameron County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 29, 1900, to March 31, 1914 (discharge not computed) ; October 1, 1922, to September 30, 1923.

GAGE. Vertical staff in two section on right bank 40 feet below cable; read by 

Pablo Guerra. All gages to same datum.
114 SURFACE WATER, SUPPLY, 1923, PART VIII

DISCHARGE MEASUREMENTS. Made from cable near gage.

CHANNEL AND CONTROL. Bed of stream composed of sand; shifting. Channel 

is straight for 500 feet above and 2,000 feet below station. Banks subject 

to overflow at extremely high stages. Control is a stretch of channel.

EXTBEMES OF DISCHARGE. Maximum mean daily discharge, 25,500 second-feet 

September 12 and 13; minimum mean daily discharge, 386 second-feet 

May 25.

DIVERSIONS. Considerable water diverted in Colorado, New Mexico, Texas, and 

Mexico; amount not known.

Between Roma and Brownsville many lagoons '( old river channels) takeriver water during moderate floods, and a large area is overflowed deeply 

in large floods. Much of this water returns slowly to the river as thefloods subside, thus making the flow more uniform at Brownsville than at 

Roma. During extremely high stages large quantities also leave the river 

entirely, reaching the Gulf of Mexico by other channels.

REGTTLATION. Flow partly regulated by storage at Elephant Butte Dam, 120 

miles above El Paso.

ACCURACY. Stage-discharge relation not permanent. Gage read to half-tenths 

twice daily. Discharge determined principally from ..frequent discharge 

measurements.

PECOS BIVEB NEAR DAYTON, N. HEX.

LOCATION. In sec. 13, T. 18 S., R. 26 E., 3 miles east of Dayton, Eddy County, 

half a mile above mouth of Penasco River.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. March 24, 1905, to September 30, 1923.

GAGE. Stevens water-stage recorder on right bank; installed August 27, 1914.

DISCHARGE MEASUREMENTS. Made from cable.

CHANNEL AND CONTROL. Bed composed of sand and gravel; shifts, especially 

during high stages. Right bank consists of clay; left bank of sand. 

Banks are overflowed at stage of about 11.5 feet. Control not well 

defined.

EXTREMES OF DISCHARGE. Maximum mean daily stage, 10.60 feet on June 10 

(discharge, 2,130 second-feet) ; minimum mean daily discharge, 20 secondfeet August 16 and 18.

1905-1923: Maximum stage recorded, 15.9 feet for five or six hours 

during morning of September 18, 1919 (discharge not determined; probably exceeded previous maximum of 50,300 second-feet on July 25, 1915, 

which was derived from discharge at Lake McMillan and included flow 

of Penasco River) ; minimum stage, that of August 16 and 18, 1923.

ICE. None reported.

DIVERSIONS. Considerable water is diverted above station for irrigation; 

quantity not known, but not in conflict with rights of Carlsbad project of 

the United States Bureau of Reclamation, which serves about 20,000 

acres near Carlsbad and stores part of the water used near Carlsbad in 

Lake McMillan, 10 miles below gage.

REGULATION. None.

ACCURACY. Stage-discharge relation not permament, but periods of change 

are covered by discharge measurements. Curve well defined from 30 to 

1,100 second-feet, and extended parallel to former curves to cover range 

of stage. Operation of water-stage recorder satisfactory, except as noted 

in footnote to daily discharge table. Mean daily gage heights determined 

from recorder graph by inspection or by averaging gage heights for fractional parts of a day. Daily discharge ascertained by shifting-control 

method, using mean daily gage height except for days of considerable 

range in stage, when discharge was averaged for fractional parts of the 

day. Records good.

FECOS KIVEK NEAR MALAGA, N. MEX.

LOCATION. In sec. 18 or 19, T. 24 S., R. 29 E., 3% miles southeast of Malaga, 

Eddy County, and 4% miles below mouth of Black River.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 1, 1920, to September 30, 1923.

GAGE. Stevens seven-day water-stage recorder installed on right bank, with 

staff gage attached to still well; inspected by W. F. Gerlach.

DISCHARGE MEASTJBEMENTS. Made from cable or by wading.

CHANNEL AND CONTROL. Bed composed of solid rock covered with sand; shifts. 

Right bank solid rock and steep. Left bank sand and high. Control is 

rock ledge overlain with sand 500 feet below gage; Shifts.

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

recorder, 8.83 feet at 11.50 a. m. August 28 (discharge 4,640 second-feet); 

minimum stage, 3.42 feet at 9 p. m. April 7 (discharge, 36 second-feet, 

determined from extension of rating curve and subject to error).

1920-1923: Maximum stage from water-stage recorder, 12.85 feet at 

1 a. m. June 8, 1921 (discharge, 22,000 second-feet, determined from extension of curve and subject to error) ; minimum stage that of April 7, 1923.

In September, 1919, river reached a stage of 26.4 feet (discharge not 

determined).

DIVERSIONS. The Carlsbad project of United States Bureau of Reclamation, 

with reservoirs that have a capacity of 58,500 acre-feet, diverts a large 

part of the natural run-off above Carlsbad, N. Mex. During season of 

irrigation considerable water is returned to the stream by seepage from 

lands near Carlsbad. In addition to water used by the Carlsbad project, 

some diversions are made for irrigation in the basin above storage 

reservoirs of the Carlsbad project.

REGULATION. Operation of the water-power plant of 300 horsepower capacity 

above station, just below Carlsbad, N. Mex., owned and operated by Carlsbad Electric Light & Power Co., 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 water, but during 

the winter the flow depends on water released at the reservoirs.
120 SURFACE WATER SUPPLY, 1923, PART VIII

ACCURACY. Stage-discharge relation not permanent. Two rating curves used; 

one applicable from October 1 to December 31 and the other from January 

1 to September 30, both of which are well defined for all stages. Operation of water-stage recorder satisfactory. Mean daily gage height obtained 

from recorder chart by inspection or by averaging gage heights for fractional parts of a day. Daily discharge determined by shifting-control 

method, using mean daily gage height except for days of considerable range 

in stage, when discharge was averaged for fractional parts of the day. 

Records good.

COOPERATION. Most of discharge measurements and records of daily dischargefurnished by United States Bureau of Reclamation.

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

banks not subject to overflow. Control formed by a series of rapids 

200 feet below gage; shifts.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage recorder, 6.84 feet at 2.15 a. m. September 16 (discharge, 12,400 second-feet, 

determined from extension of curve parallel to curve for 1921) ; minimum 

discharge, 68 second-feet August 19 and 20.

1914-1923: Maximum stage recorded, 21.5 feet at 10 a. m. August 8, 1916, 

measured by leveling from floodmarks (discharge not determined) ; minimum discharge, that of August 19 and 20, 1923.

ICE. Stage-discharge relation not seriously affected by ice; open-channel 

rating assumed applicable.

DIVERSIONS. The Carlsbad project of the United States Bureau of Reclamation, 

with reservoirs that have 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 

lands near Carlsbad. In addition to the water used by the Carlsbad 

project some diversions are made for irrigation in the basin above the 

storage reservoir of the Carlsbad project.

REGULATION. Operation of a water-power plant of 300 horsepower capacity 

above station, just below Carlsbad, N. Mex., owned and operated by Carlsbad Electric Light & Power Co., 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 winter 

flow depends on water released at the reservoirs.
122 SURFACE WATER SUPPLY, 1923, PART VIII

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

above 90 second-feet, and extended below to cover range of stage for year. 

Operation of water-stage recorder not satisfactory. Mean daily heights 

obtained from recorder graph by inspection or by use of planimeter. 

Daily discharge determined by shifting-control method, using mean daily 

gage heights except for days of large range in stage, when discharge was 

averaged for fractional parts of a day, and as noted in footnote to daily 

discharge table. Records fair.

FEC08 RIVER NEAR PORTERVILLE, TEX.

LOCATION. At highway bridge on Pecos-Porterville road, half a mile east of 

Arno station on Santa Fe Railway, 2 miles west of Porterville, Loving 

County.

DRAINAGE ABEA. Not measured.

RECORDS AVAILABLE. February 1, 1922, to September 30, 1923.

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

Tom Wright.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Bed composed of silt, sand, and gravel; shifts.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 10.05 feet at 

5.25 p. m. September 16 (discharge, 4,110 second-feet) ; minimum discharge, 

58 second-feet, July 4, 5, and August 2.

1922-23: Maximum and minimum stages same as given above.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. The Carlsbad project of the United States Bureau of Reclamation, 

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 considerabfe water is returned to stream by seepage from lands near 

Carlsbad. In addition to the water used by the Carlsbad project, some 

diversions are made for irrigation in the basin above storage reservoir of 

Carlsbad project.

REGULATION. Operation of a water-power plant of 300 horsepower capacity 

above station, just below Carlsbad, N. Mex., owned and operated by Carlsbad Electric Light & Power Co., 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 winter 

flow depends on water released at reservoirs.

ACCURACY. Stage-discharge relation not permanent. Rating curve well defined from 60 to 400 second-feet and fairly well defined above 400 secondfeet. Gage read to hundredths once a day; reading may not be a true 

index to mean daily discharge at high stages, owing to rapid fluctuations. 

Daily discharge determined by shifting-control method, except as noted 

in footnote to daily discharge table. Records fair.

County.

DRAINAGE AEEA. Not measured.

EECOBDS AVAILABLE. February 1, 1916, to May 11, 1921; March 22, 1922, to 

September 30, 1923.

GAGE. Stevens continuous water-stage recorder on left bank. Prior to March 

4, 1923, Gurley eight-day water-stage recorder on left bank; attended by 

R. G. Hamilton or engineers of United States Geological Survey. Gage 

used 1916-1921 was a Stevens continuous water-stage recorder at a site 4 

miles upstream.

DISCHARGE MEASUREMENTS. Measurements made by wading or from cable near 

gage, or from Texas Pacific Railroad bridge near Pecos.

CHANNEL AND CONTROL. Channel straight for several hundred feet above and 

below station. Bed composed of rock; permanent. Banks of silt and sand, 

steep; shift. Left bank not subject to overflow. Right bank subject to 

overflow at extremely high stages. Low-water control is rock ledge 150 

feet below gage; permanent. Point of zero flow is gage height 1.3 feet.

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

7.50 feet at 5.20 a. m. September 17 (discharge, 2,900 second-feet) ; minimum discharge, 0.2 second-foot April 27-29, June 25 to July 10, July 13-20, 

and July 24 to August 21.

1915-1923: Maximum stage from water-stage recorder, 12.1 feet from 

gage (at original site) at 6 a. m. August 10, 1916 (discharge not determined) ; minimum stage same as given above.

DIVERSION. In addition to water diverted in New Mexico by the Carlsbad 

project, the three principal diversions in Texas are the Farmers Independent, Cedarvale (formerly Biggs), and Barstow Canals. Small amount 

diverted by Boxley and Porterville irrigation systems. According to records 

of the Board of Water Engineers for the State of Texas, these projects 

have declared a total of 17,500 acres irrigated.

REGULATION. Flow during low and medium stages regulated by storage 

reservoir on Carlsbad project in New Mexico and by diversion dams in 

Texas. Flood flow partly regulated by reservoirs on Carlsbad project. 

4241 27 WSP 568 9
126 SURFACE WATER SUPPLY, 1923, PAET VIII

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

below 1,000 second-feet and fairly well defined from 1,000 to 3,000 secondfeet. Operation of water-stage recorder not satisfactory prior to March 3, 

principally due to improper attendance. Daily discharge determined by 

shifting-control method, using mean daily gage height except for days of 

considerable range in stage, when discharge was averaged for fractional 

parts of the day, except as noted in footnote to daily discharge table.

PECOS BITER NEAR GEANDFALLS, TEX.

LOCATION. At site of old highway bridge where Grandfalls-Fort Stockton road 

formerly crossed Pecos River, 1% miles upstream from present GrandfallsFort Stockton road crossing at iron bridge, 2 miles below diversion dam 

for the low-line (silt-line) canal of the Imperial Irrigation Co., about 3 

miles south of Grandfalls, Ward County, and 4% miles above diversion 

dam of Zimmerman project.

DRAINAGE ABEA. Not measured.

RECOEDS AVAILABLE. August 4, 1917, to September 30, 1923, at present site; 

November 6, 1915, to August 3, 1917, at iron bridge, 1% miles downstream 

from present site. Discharge at both points believed to be the same.

OAGE. Stevens water-stage recorder installed August ,9, 1917, on downstream 

side of old bridge pier near left water's edge; inspected by engineers of 

United States Geological Survey.

DISCHABGE MEASTTBEMENTB. Made by wading near gage, from cable 50 feet above 

gage, or during extremely high stages at iron bridge.

CHANNEL AND CONTBOL. Bed of stream solid rock and permanent, except for 

small deposits of sand and gravel. Channel straight for 100 feet above and 

below station. One channel below gage height of 8 feet; above this stage 

banks, which are dirt and wooded, are subject to overflow. Rock ledge 

extends diagonally across stream just below gage and serves as low-water 

control; shifts, due to clogging of crevices.

EXTBEMES OP DISCHABGE. Maximum stage during year from water-stage recorder, 3.72 feet at 4.30 p. m. September 18 (discharge, 1,990 secondfeet) ; minimum discharge, 0.80 second-foot at 5 a. m. July 18, determined 

from extension of rating curve and subject to error.

1915-1923: Maximum stage from water-stage recorder, 9.6 feet from 

2 to 6 a. m. September 25, 1919 (discharge 13,000 second-feet) ; minimum 

discharge, less than 0.7 second-foot April 17, 1916.

DIVEBSIONS. Station is 2 miles below diversion of low-line (silt-line) canal 

of the Imperial Irrigation Co., 18% miles below diversion for the Imperial 

Reservoir (capacity, 17,000 acre-feet), 25% miles below diversion for Ward 

County Water Improvement District No. 2 (of which the old Grandfalls 

project is a part), and 4% miles above diversion for Zimmerman project 

Available data show that tracts aggregating about 143,000 acres are irrigable between station and lower limits of Carlsbad project of the United 

States Bureau of Reclamation. Records of the Board of Water Engineers 

for the State of tfexas show total number of acres declared irrigated in
128 SUEFAOE WATER SUPPLY, 1923, PART VIII

Texas above station to be about 58,000. The effect of diversions is somewhat counterbalanced by water returned to stream by seepage. The only 

diversion of importance below the station is that for the Zimmerman project, which has been declared an irrigated area of 2,005 acres.

REGULATION. Slight regulatory effect caused by operation of storage reservoirs 

on Carlsbad project.

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

from 2 to 15,000 second-feet. Operation of water-stage recorder satisfactory, except for short breaks in record. Daily discharge determined by 

shifting-control method, using mean daily gage height except for days of 

considerable range in stage, when discharge was averaged for fractional 

parts of a day, and as noted in footnote to daily discharge table. Records fair.

PECOS RIVER NEAR BUENA VISTA, TEX.

LOCATION. At highway bridge on Fort Stockton-Midland road, 4% miles east 

of Buenavista, Pecos County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. December 5, 1921, to September 30, 1923.

GAGE. Stevens continuous water-stage recorder, attached to left abutment 

at downstream side of bridge.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Bed composed of silt, sand, and gravel; shifts. 

Banks are overflowed during extremely high stages.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage recorder, 4.14 feet at 2 p. m. September 19 (discharge, 992 second-feet, determined from extension of rating curve and subject to error) ; minimum 

discharge, 15 second-feet July 17 to 18.

1921-1923: Maximum and minimum stages occurred in 1923 as given 

above.

DIVERSIONS. Station is below all diversions. During much of time practically 

the only flow past station is waste and seepage water from the irrigated 

area above gage.

REGULATION. Flow regulated by storage and diversion dams in New Mexico 

and Texas.

ACCURACY. Stage-discharge relation not permanent. Rating curve well defined from 25 to 600 second-feet, and extended above and below this to 

cover range of stage for the year. Operation of water-stage recorder satisfactory, except for short breaks in record. Daily discharge ascertained 

by applying to rating table mean da.ily gage height determined from 

recorder graph by inspection, by use of planimeter, or by averaging discharge for fractional parts of a day; shifting-control method used April 

28 to September 30. Records good.

FECOS RIVER NEAR SHEFFIELD, TEX.

LOCATION. At highway bridge on Fort Stockton-Ozona road, 3% miles east 

of Sheffield, Pecos County, and 41 miles west of Ozona.

DRAINAGE AKEA. Not measured.

RECORDS AVAILABLE. October 10, 1921, to September 30, 1923.

GAGE. Chain gage attached to upstream side of bridge; read by Kyle Smith. 

Auxiliary staff gage attached to pier near left bank.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

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

bank not subject to overflow; left bank is overflowed during extremely 

high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.32 feet at 

6.30 p. m. September 7 (discharge, 2,360 second-feet, determined from extension of rating curve and subject to error) ; minimum discharge, 15 

second-feet at 6 p. m. August 15, determined from extension of rating 

curve and subject to error.

DIVERSIONS. Station is below all diversions. During much of the time practically the only flow past station is waste and seepage water from irrigated 

area above.

REGULATION. Flow partly regulated by storage and diversion dams in New 

Mexico and Texas.

ACCURACY. Stage-discharge relation not permanent. Rating curve poorly defined from 100 to 700 second-feet, and extended to cover range of stage 

for year". Gage read twice daily to hundredths, but readings were unreliable and it was necessary to estimate most of the year. Daily discharge, March 4-31 and May 18 to September 30, determined by shiftingcontrol method; discharge for remainder of year estimated. Records of 

daily discharge not sufficiently accurate to warrant publication. Records 

poor.

PECOS RIVER NEAR COMSTOCK, TEX.

LOCATION. At Pecos High Bridge of Galveston, Harrisburg & San Antonio 

Railway Co., 11 miles west of Comstock, Val Verde County, and beltnv 

all tributaries.

DRAINAGE AEEA. Not measured.

RECORDS AVAILABLE. May 1, 1900, to September 30, 1923. (Also gage heights 

for 1898).

GAGE. Vertical staff attached to downstream side of bridge pier on left bank; 

read by W. A. Clare. Datum of section of gage below 6.7 feet as used 

January 10, 1917, to September 30, 1922, was 0.05 foot higher than presenl 

datum; no change in datum of gage above 6.7 feet.

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.

EXTREMES OP DISCHARGE. Maximum stage recorded, 2.60 feet at 7 a. m. 

September 17 (discharge, 1,500 second-feet) ; minimum stage, 0.13 foot 

August 6-8, 10-13, 15, 16, and 19-22 (discharge, 149 second-feet).

1900-1923: Maximum stage recorded, 35.75 feet April 6, 1900 (discharge 

not determined) ; minimum discharge recorded, 106 second-feet July 29 

to August 1, 1918.

ICE. None reported.

DIVERSIONS. Considerable water is diverted and stored above station for 

irrigation. Lakes McMillan and Aval on of the Carlsbad project of th« 

United States Bureau of Reclamation, 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 near Barstow and Grandfalls, Tex. 

No diversions below station. Return waters tend to equalize effects of 

diversions in lower part of drainage basin.
EIO GRANGE BASIN 133

REGULATION. Flow partly 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 30u horsepower, 

near Carlsbad, N. Mex.

ACCURACY. Stage-discharge relation permanent during year. Rating curve 

well denned for all stages during year. Gage read to hundredths twice 

daily, but observer's work doubtful. Daily discharge determined by applying mean daily gage height to rating table. Records fair.

CEDARVALE CANAL NEAR BARSTOW, TEX.

LOCATION. At head gates of canal, 1% miles above Ward County Irrigation 

District, District No. 1 (Barstow) Dam and 10 miles northwest of Barstow, Ward County. Prior to August 21, 1923, station was at highway
136 SURFACE WATER SUPPLY, 1923, PART VIII

bridge across canal near Barstow Canal head gates, below Boxley Canal 

pumping plant, 1% miles above present site.

RECORDS AVAILABLE. February 12, 1922, to September 30, 1923.

GAGE. Stevens eight-day water-stage recorder; attended by R. G. Hamilton or 

engineer from United States Geological Survey Office.

DISCHARGE MEASUREMENTS. Made by wading near gage.

EXTREMES OP DISCHARGE. Maximum stage not known. No flow for several 

periods.

DIVERSIONS. The Boxley Canal diverts water from this canal between river and 

lower location of gage, but only at times when there is no flow past lower 

location of gage.

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

Operation of water-stage recorder not satisfactory. Daily and monthly discharge not determined on account of poor gage-height record and backwater conditions. Total discharge for year estimated at 12,800 acre-feet 

from incomplete gage-height record, comparison with records for other 

stations, and discharge measurements. Records poor.

Canal diverts from left bank of Pecos River between Farmers Independent 

Canal and Barstow Canal.

DISCHARGE MEASUREMENTS. Made by wading or from a bridge 300 leet above 

gage.

CHANNEL AND CONTROL. Bed composed of coarse gravel. Point of zero flow, 

0.20 foot gage datum.

EXTREMES OF DISCHARGE. Maximum stage during year, from marks on recorder 

well, was 6.85 feet September 18, during period when recorder was not 

operating properly (discharge not determined). No flow ;for several 

periods.

1922 and 1923: Maximum stage, that of September 18, 1923. No flow 

for several periods.

DIVERSIONS. Above all diversions. Sand gates 300 feet above are opened occasionally for a short time to clean canal.

ACCURACY. Stage-discharge relation not permanent. Rating curve well defined from 0 to 150 second-feet, and extended to cover range of stage for 

year. Operation of water-stage recorder not satisfactory. Mean dally 

gage heights determined from recorder graph by inspection or by use of 

planimeter. Daily discharge determined by shifting-control method, except as noted in footnote to daily discharge table. Records poor.

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 result of stream-flow measurements xire 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 (St. John River to York River).

II. South Atlantic and eastern Gulf of Mexico basins (James River to the 

Mississippi).

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.

HOW GOVERNMENT REPORTS MAY BE OBTAINED OR CONSULTED

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 prjor 

to 1904 has been published in Water-Supply Paper 119.
148 SURFACE WATEE SUPPLY, 1923, PART VIII

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

1923. 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 Kiver at Whitneyville, 

Maine, 1903 to 1921, are published in Water-Supply Papers 97, 124, 

165, 201, 241, 261, 281, 301, 321, 351, 381, 401, 431, 451, 471, 501, and 

521, which contain records for the New England streams from 1903 

to 1921. Results of miscellaneous measurements are published by 

drainage basins.

150 SURFACE WATER SUPPLY, 1923, PART VIII

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 145, and the records for 

large lakes are taken up in order of streams around the rim of the 

lake.

PBINCIPAL STBEAMS

The western Gulf of Mexico drainage basins include all streams 

draining into the Gulf of Mexico west of the mouth of the Mississsippi 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 

p. 162.)

162 SURFACE WATER SUPPLY, 1923, PAET VIII

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.2 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 areal-geology map shows 

the distribution of the various rocks at the surface. The structural-geology 

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
