stage and contents of lakes and reservoirs have been made at about 11,680 gaging stations 

in the 48 States and also at many In the Territories of Alaska and Hawaii. On September 

30, 1949, 6,240 gaging stations, including those in Hawaii and Alaska were being maintained by the Geological Survey and cooperating organizations. Miscellaneous discharge 

measurements, were made during the water year at many other points.

In the execution of the work many State and private organizations have cooperated, 

either by furnishing data or by assisting In collecting data. Cooperation of the first 

kind Is acknowedged in connection with the description of each station affected; cooperation of the second kind is acknowledged, under the heading "Cooperation," In the Introductory matter that precedes the gaglng-station records In each volume. In the present 

volume, the section on cooperation of the second kind appears on page 13.

DEFINITION OP TERMS

The units In which stream-flow data are presented in this report and other terms used 

herein are defined as follows:

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

rate of discharge of a stream whose channel Is 1 square foot In cross-sectional area and 

whose average velocity is. 1 foot per second.

"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 ths runoff is distributed uniformly both as regards time and area.

"Runoff in Inches" is the depth to which an area would be covered If all the water 

draining from it In a given period were uniformly distributed on Its surface. It is used 

for comparing runoff with rainfall, which Is usually expressed In inches.

An "acre-foot" Is the quantity of water required to cover an acre to the depth of 

1 foot and is equivalent to 43,560 cubic feet. The term is commonly used In connection 

with storage for irrigation.

"Second-foot-day" is the volume of water represented by a flow of 1 second*-foot for 24 

hours. It Is equivalent to 86,400 cubic feet, 1.983471 acre-feet, or 646,317 gallonsand 

represents a runoff of 0.0378 inch from 1 square mile.

"Stage-discharge relation" Is an abbreviation for the t*rm "relation between gage Heigh' 

and discharge. 11

"Control" Is a term used to designate a feature downstream from the gage that determines the stage-discharge relation at the gage, This feature may be a natural section, 

a reach of the channel, or an artificial structure. " ' 
2 SURFACE WATER SUPPLY, 1949, PART 8

"Contents" is a term applied to the volume of water in a reservoir. Unless otherwise 

indicated, it is computed on the basis of a level pool and does not Include bank storage.

EXPLANATION OP DATA

The base data collected at gaging stations consist of records of stage, measurements 

of discharge, and general information used to supplement the records of stage and discharge 

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

direct readings on a nonrecording 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. Typical structures in use at gaging stations are shown in figure 1.

Rating tables giving the discharge for any stage are prepared from the discharge measurements. The application of the daily mean gage height to those rating tables gives the 

daily mean discharge, from which the monthly and the yearly mean discharge are computed. 

If the stage-discharge relation is subject to change because of frequent or continual 

change in the physical features that form the control, the daily mean discharge is determined by the "shifting-control method," in which correction factors based on individual discharge measurements and notes by engineers and observers are used in applying the 

gage heights to the rating tables. At times the stage-discharge relation for a station 

may be temporarily changed by the presence of aquatic growth or debris on the control. 

For such times the daily mean discharge is computed by what is essentially the "shiftingcontrol" method, described above.

At some gaging stations the stage-discharge relation is affected by backwater from 

reservoirs, tributary streams, or other sources, which necessitates the use of the "slope 

method," in which the slope or fall in a reach of the stream is a factor in the determination of discharge. Information requisite for determining the slope or fall is obtained 

by means of an auxiliary gage set at some distance from the base gage. At some stations 

the stage-discharge relation is affected by changing stage, and for them the rate of 

change of stage is used as a factor in the determination of discharge.

At most gaging stations in the northern part of the United States and at some in the 

mountainous regions of other parts the stage-discharge relation is affected by ice during 

the winter, which makes it impossible to compute the discharge in the usual manner. Discharge for periods of ice effect is computed on the basis of the gage-height record and 

occasional.winter discharge measurements, consideration being given to the available information on temperature and precipitation, notes by gage observers and engineers, and 

comparable records of discharge for stations in the same or nearby basins. For those 

stations at which the stage-discharge relation 1,8 affected by ice, the days included in 

the periods of ice effect either are indicated in the table by symbols referring to a 

footnote that states this fact or are given in a general note following the table. The 

days on which discharge measurements were made during or between periods of ice effect, 

shortly before the first period, or shortly after the last period are similarly indicated 

by a footnote.

For most of the gaging stations on streams in the area covered by this report the data 

presented comprise a description of the station, a table showing the daily discharge of

the stream, and a table of monthly and yearly discharge and runoff. Skeleton rating

tables are published for all stations except those at which the daily discharge for the 

greater part of the year was determined by the shifting-control method, the slope method, 

or other special methods.

The description of the station gives the type of gage, location, drainage area, records 

available, average discharge, extremes of discharge, general remarks, and notations of revisions of previously published record. The location of the gaging station and the drainage area are obtained from the most accurate maps available. Under "Average discharge" is 

given the average discharge for the number of years indicated. It is not given for stations having less than 10 complete years of record or for stations where changes in water 

development during the period of record cause the figure to have little significance. 

Under "Extremes" are given the maximum discharge and gage height; the minimum discharge if 

there is little or no regulation; the minimum daily discharge if there is extensive regulation (also the minimum discharge if useful); and. the minimum gage height (unless it is 

of no Importance). Unless otherwise qualified, the maximum discharge corresponds to the 

crest stage, obtained by use of a water-stage recorder or a nonrecording gage read at the 

time of the crest. Information pertaining to the accuracy of the records and conditions 

which affect the natural flow at the gaging station is given under "Remarks."

For some stations previously published records have been found to be in error on the 

basis of data or information obtained subsequently. Revisions of such records are usually 

published along with the current records in one of the annual reports. In order to make 

it easier to find such revised records, a paragraph headed "Revisions (water years)" has 

been added to the station description of all stations for which revised records have been 

published. Listed therein are all the reports in which revisions appear, each followed by 

the water years for which figures are revised in that report. In listing the report 

number, W. means Water-Supply Paper. In listing the years, water years are indicated by 

only 1-year, for instance, 1933 stands for the water year October 1, 1932, to September 30, 

1933. If there were no daily, monthly, or annual figures of discharge involved in the 

revision, that fact is brought out by notations after the year dates as follows: (M) means 

that only the instantaneous maximum discharge was revised; (m) that only the instantaneous 

minimum was revised; and (P) that only peak discharges were revised. If the drainage area 

has been .revised, the report in which the revised figure was first published is given. It 

should be noted that for all stations for which second-feet per square mile and runoff in 

inches are published, a revision of the drainage area necessitates corresponding revision 

of ail figures based on the drainage area. Revised figures of second-f«et per square mil*

d ^

and runoff in inches resulting from a revision of the drainage area only are usually noti^ 

published in the annual series of reports.

For stations equipped with water-stage recorders, except those on streams subject to 

sudden or rapid fluctuation, the table gives the discharge corresponding to the daily mean 

gage height. For stations subject to such fluctuation the dally mean gage height may not 

indicate the true daily mean discharge, which must be obtained by averaging the discharge 

for parts of the day or by using the discharge integrator, an instrument for obtaining the 

daily mean discharge from a continuous gage-height graph and containing as an essential 

element a curve representing the stage-discharge relation at the station. For stations 

.equipped with nonrecording gages, the table of daily discharge gives the discharge
ACCURACY OP FIELD DATA AP COMPUTED RESULTS 5

corresponding to either once-daily readings of the gage, the mean of twice-daily readings, 

or the mean gage .height determined from gage-height graphs based on gage readings. For 

periods of rapidly changing stage, the dally mean discharge Is determined from gage-height 

graphs based on gage readings, the frequency of which Is stated In the station description.

In the table of monthly discharge the column headed "Second-foot-days" gives the sum 

for each month of the figures given In the table of daily, discharge. The column headed 

"Maximum" gives the maximum dally discharge, not the momentary discharge when the water 

surface was at crest stage. Likewise, In the column headed "Minimum" the quantity given 

is the minimum dally discharge. The column headed "Mean" gives the average flow in cubic 

feet per second during the month.

Peak discharges with the times of their occurrence are listed below the table of monthly 

discharge for most stations. All Independent peaks above the selected base are given. The 

base discharge, which is given in parentheses, Is selected so that an average of about 

three peaks a year will be presented. Peak discharges are not published for canals, 

ditches, drains, or for any stream for which the peaks are subject"to substantial control 

by man.

For most gaging stations on lakes and reservoirs the data presented comprise a description of the station and a monthly summary table of stage and contents. For some reservoirs a table showing daily contents or stage is given. A skeleton table of capacity at 

given stages is usually given in the first report in which data for a station are published 

but is omitted from succeeding reports.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream-flow data depends primarily on (1) the permanency of the stagedischarge relation or, if the control is unstable, the frequency of discharge measurements 

and (8) the accuracy of observations of stage, measurements of flow, and interpretation of 

records.

The station description gives a statement in regard to the general accuracy of the records. "Excellent" indicates that, in general, the error in the daily records is believed, 

to be less than 5 percent; "good," less than 10 percent; "fair," less than 15 percent; and 

"poor," probably more than 15 percent. The records of monthly and yearly mean discharge 

and runoff are, In general, more accurate than the daily records.

Yield at some stations as indicated by monthly means may vary widely from natural yield, 

owing to diversion, consumption, regulation by storage, increase or decrease In evaporation 

due to artificial causes, or other factors. For such stations figures of "second-feet per 

square mile" and "runoff in Inches" are not published unless storage or diversion records 

are included indicating the extent of the regulation or diversion or unless satisfactory 

adjustments can be made for changes in contents or reservoirs or for other changes incident 

to use and control. Evaporation from a reservoir is not Included in the adjustments for 

changes in reaervoir contents, unless its inclusion is indicated,, Even at those stations 

where adjustments are made, in some Instances large errors in computed yields may,qeeur 

when relatively large negative adjustments are applied or when evaporation is large in 

comparison with the observed discharge. Figures of second-feet per square mile ^and runoff 

in inches are also omitted if the drainage area includes large noncontributing areas or if 

the average annual rainfall over the drainage area is less than 30 inches, ' ,
6 SURFACE WATER SUPPLY, 1949, PART 8

Many gaging stations on streams in the irrigated areas of the United States are situated 

above most of the diversions from those streams, and therefore the discharge recorded does 

not show the water supply available for further development, as prior appropriations below 

the station must first be satisfied.

The table of monthly discharge presents in summary the distribution of the flow past the 

station. The table of daily discharge affords opportunity for more detailed studies of the 

variation in flow. As further observations in each succeeding year may be expected to 

throw new light on data previously published, it should be borne in mind that such data are 

subject to revision in succeeding water-supply papers.

f Computed on basis of partly estimated gage-height record.

Note.- Ho recorder record June 21-23, June 29 to July 26; discharge computed from graph based on 

once-daily wire-weight gage readings. Baakwater from return flow from overbank storage Jan. 25-29, 

Feb. 26 to Mar. 1, Mar. 27-30, May 21-26, May 28 to June 8, June 16-20, 26-28; discharge computed on 

basis of loop curves.
54 TRINITY RIVER BASIN

Trinity River near Rosser, Tex.

Location.- Water-stage recorder, lat. 32°25'40", long. 96°27'50", at bridge on State High-

 Way 34, 1.4 miles downstream from Texas & New Orleans Railroad bridge, 1.9 miles downstream from East Pork, and 2.5 miles south of Rosser, Kaufman County. Datum of gage is 

302.6 feet above mean sea level, datum of 1929.

Drainage area.- 8,162 square miles (revised).

Records available.- November'1938 to September 1949. July 1924 to September 1925 (October

 19^4 to September 1925, gage heights only) at site 1.7 miles upstream.

Average discharge.- 10 years (1339-49), 3,635 second-feet.

Extremes.- Maximum discharge during year, 51,900 second-feet May 21 (gage height, 38.04

 feet); minimum, 133 second-feet Dec. 13 (gage height, 4.45 feet).

1924, 1938-49: Maximum discharge not determined, but occurred Apr. 23 or 24, 1942, 

following numerous breaks in levee system on both banks; maximum gage height, 41.55 feet 

Apr. 22, 1942, Just prior to levee breaks: minimum discharge, 34 second-feet Sept. 8-11, 

1924.

Flood of May 1908 reached a stage of about 33.0 feet, present site and datum, from 

information by Corps of Engineers (discharge believed to have been approximately the same 

as that of Apr. 23 or 24, 1942). 

Remarks.- Records good except those for period of no gage-height record, which are fair.

 Plow partly regulated by reservoirs above Dallas. Levee system constructed in 1916. 

Cities of Port Worth and Dallas divert considerable water for municipal supply. Several 

small diversions on West Fork above Port Worth.

bridge. Datum of gage is 2.22 feet below mean sea level, datum of 1929.

Drainage area.- 17,539 square miles (revised).

Records available.- October 1938 to September 1940 (gage heights, discharge measurements, 

ana some records of daily discharge), October 1940 to September 1949. U. S. Weather 

Bureau has collected gage-height records in this vicinity since 1903.

Extremes.- Maximum discharge during year, 28,100 second-feet Apr. 24 (gage height, 25.90 

reet, from graph based on gage readings); minimum not determined (affected by tides); 

minimum gage height observed, 4.03 feet Nov. 10.

1938-49: Maximum discharge, 114,000 second-feet May 12, 1942 (gage height, 29.38 

feet); minimum discharge not determined (affected by tides); minimum gage height 

observed, 2.5 feet Nov. 4, 1939.

A stage of 28.6 feet was reached May 8-11, 1922, from observation by U. S. Weather 

Bureau at chain gage on railroad bridge upstream.

Remarks.- Records good. Gage read once daily. Discharge not computed below 10-foot gage 

neight because tides affect stage-discharge relation.

Cooperation.- Gage readings furnished by U. S. Weather Bureau.

80 SAN JACINTO RIVER BASIN 

Barker Reservoir near Addicks, Tex.

Location.- Water-stage recorder, lat. 29°.46'05", long. 95°38'45", at dam on Buffalo Bayou,

 4b i'e'et upstream from reservoir outlet works, 1,160 feet upstream from Addicks-Howell 

county road, 1.1 miles south of Addicks, Harris County, and 1.2 miles upstream from 

South Mayde Creek. Auxiliary water-stage recorder, lat. 29°43'10", long. 95 44'00 , 

on Buffalo Bayou, 2.8 miles west of Clodine, Fort Bend County, 4.8 miles (2.7 miles 

by reservoir) upstream from Mason Creek, 9.0 miles (6.4 miles by reservoir) upstream 

from reservoir outlet works. Datum of both gages is 0.3 foot below mean sea level, 

datum of 1929, Galveston-Houston supplementary adjustment and Houston supplementary 

adjustment of 1943.

Drainage area.- 150 square miles at outlet works; 105 square miles at upper gage. 

Records available.- August 1945 to September 1949.

Extremes.- Maximum gage height at dam during year, 82.8 feet Apr. 24, 25 (contents, 222

 acre-feet); maximum at upper gage, 96.6 feet Apr. 23, 24.

1945-49: Maximum gage height at dam, 90.4 feet Aug. 30, 1945 (contents, 11,240 

acre-feet); maximum at upper gage, 98.6 feet Aug. 28, 1945.

Maximum stage known near site of upper gage prior to construction of reservoir, 98.1 

feet in December 1935, from floodmark about 1,100 feet to right of and 1,100 feet downstream from upper gage.

Remarks.- Reservoir is formed by rolled-fill earthen-type dam 72,844 feet long. Dam cora-

 plefed Feb. 3, 1946, but was first- used for flood control in spring of 1945. Reservoir 

is operated for flood protection of city of Houston. It is a detention reservoir with 

no provision for permanent storage. Outlet works consist of five concrete conduits, 

two of which are uncontrolled. The middle conduit is controlled by two vertical-lift 

steel gates; the two outer conduits are controlled by single vertical-lift steel 

gates, which were installed during spring of 1949. .All gates remain closed except 

during recession of large, floods or during emergencies. Capacity, 127,900 acre-feet 

between gage heights 75.0 feet (bottom of conduits) and 101.9 feet (top of design flood 

pool). No constructed emergency spillways; runoff considerably in excess of designed 

capacity will be discharged around ends of dam. Gage heights and contents not published for floods that do not produce a gage height of 82.0 feet (top of outlet structure) or higher at dam. Table given below shows gage heights at both gages and total 

contents, computed on basis of gage at dam, at indicated times for periods when flood 

runoff was partially stored in reservoir. Gage height at upper gage is given to show 

whether an existing stage at that site is due to normal stream flow or to flood storage 

in reservoir.

Cooperation.- Capacity table furnished by Corps of Engineers.

Gage height and contents, at indicated time when flood runoff was 

partly stored in reservoir, during period April to May 1949

SAN JACINTO RIVER BASIN 83

Addicks Reservoir near Addicks, Tex.

Location.- Water-stage recorder, lat. 29°47'30",. long. 95°37'25", at dam on South Mayde 

Creek, 65 feet upstream from reservoir outlet works, 2,700 feet upstream from U. S. 

Highway 90, 1.2 miles east of Addieks, Harris County, and 1.4 miles upstream from 

mouth. Auxiliary water-stage recorders: lat. 29°48'05", long. 95°41'30", on South 

Mayde Creek at Groesehke Road bridge, 3.2 miles west of Addieks, 4.6 miles (3..5 miles 

by reservoir) upstream from Langham Creek and 5.5'miles (4.2 miles by reservoir) upstream from reservoir outlet works; lat. 29C 50'10", long. 95 C 37'35", on Langham Creek 

at Clay Road bridge, 3.6 miles north of Addicks, 4.4 miles (2.7 miles by reservoir) 

upstream from mouth and 5.3 miles-(3.1 miles by reservoir) upstream from reservoir outlet works. Datum of all gages is mean sea level, datum of 1929, Galveston-Houston 

supplementary adjustment and the Houston supplementary adjustment of 1943.

Drainage area.- 129 square miles at outlet works; 30 square miles at gage on South Mayde 

ureek; ana 49 square miles at gage on Langham Creek.

Records available.- June 1948 to September 1949.

Extremes.- Maximum elevation at dam during year, 90.0 feet Apr. 23 (contents, 2,020 aerereet); maximum at gage on South Mayde Creek, 106.8 feet Apr. 22; maximum at gage on 

Langham Creek, 101.7 feet Apr. 22.

1948-49: Maximum elevation at dam, that of Apr. 23, 1949; maximum at gage on South 

Mayde Creek, that of Apr. 22, 1949; maximum of gage on Langham Creek, that of Apr. 22, 

1949.

Maximum stage known, 89.9 feet in December 1935 at U. S. Highway 90 bridge, 2,700 

feet downstream from outlet works, from information by Corps of Engineers. This 

flood, from floodmarks, from information by local residents, reached a stage of 109.3 

feet, 0.2 mile downstream, and 0.1 mile to right of gage on South Mayde Creek; and a 

stage of 104.5 feet, 1,900 feet to left and 700 feet upstream from gage on Langham Creek.

Remarks.- Reservoir is formed by rolled-fill earthen-type dam 61,166 feet long. Dam 

completed In fall of 1948. Reservoir is operated for flood protection of city of 

Houston. It is a detention reservoir with no provision for permanent storage. Outlet 

works consist of five concrete conduits, two of which are uncontrolled. The middle 

conduit is controlled by two vertical-lift gates; the two outer conduits are controlled 

by single vertical-lift-steel gates, which were installed during spring of 1949. All 

gates will remain closed except during recession of large floods or during emergencies. 

Capacity, 188,030 acre-feet between gage heights 73.0 feet (bottom of conduits) and 

113.0 feet (top of design flood pool). No constructed emergency spillways; runoff considerably in excess of designed capacity will be discharged around ends of dam. Elevations and contents not published for floods that do not produce an elevation of 79.0 

feet (top of outlet structure)- or higher at dam. Table given below shows elevations 

at all gages and total contents, computed on basis of gage at dam, at Indicated times 

for periods when flood runoff was partially stored in reservoir. Elevations at auxiliary gages are given to show whether an existing stage at that site is due to normal 

flow or to flood storage in reservoir.

Cooperation.- Capacity table furnished by Corps of Engineers.

90 BRAZOS RIVER BASIN

Double Mountain Fork Brazos River at Lubboek, Tex.

Location.- Water-stage recorder and masonry control, lat. 33°35'05", long. 101C 49'40", in 

Mackenzie State Park in Lubboek, Lubboek County, 1.9 miles downstream from Yellowhouse 

Creek. Datum of gage is 3,132.7 feet above mean sea level, datum of 1929.

Records available.- September 1939 to September 1949 (discontinued). 

Average discharge.- 10 years, 1.67 second-feet.

Extremes.- Maximum discharge during year, 3,150 second-feet May 7 (gage height, 7.43 feet), 

from rating curve extended above 120 second-feet on basis of slope-area determinations 

at gage heights 6.72 and 7.43 feet; no flow most of time.

1939-49: Maximum discharge, that of May 7, 1949; no flow most of time

Remarks.- Records good. Station is located in small pool (capacity, 29.5 acre-feet), 

figures of daily discharge represent inflow into pool computed on basis of outflow and 

change in contents with no correction for evaporation, transpiration, or seepage. Several dams form small pools above station which affect low flow.

BRAZOS RIVER BASIN 93

Brazos River near South Bend, Tex.

Location.- Water-stage recorder and wire-weight gage, lat. 33°01'30", long. 98°38'bO", at 

Bridge on State Highway 67, 0.3 mile upstream from Wichita Falls & Southern Railroad 

bridge, 1.6 miles downstream from Clear Fork Brazos River, and 2.0 miles northeast of 

South Bend, Young County. Datum of gage is 1,003.0 feet above mean sea level, datum 

of 1929.

Drainage area.- 21,600 square miles, of which 9,240 square miles is probably noncontributing.

Records available.- September 1938 to September 1949. 

Average discharge.- 11 years, 1,020 second-feet.

Extremes.- Maximum discharge during year, 14,300 second-feet May 17, June 12; maximum gage 

height, 11.94 feet May 17; no flow Oct. 7-10.

1938-49: Maximum discharge, 87,400 second-feet May 4, 1941 (gage height, 27.35 

feet); no flow at times.

Maximum stage known, 36.2 feet in 1876, from information by Texas State Highway 

Department and Corps of Engineers.

Remarks.- Records fair. Wire-weight gage read once daily and readings used for major 

portion of year when water-stage recorder record was not available. Flow partly regulated by reservoirs in Elm Creek Basin (see p. Ill), and Lakes Sweetwater and Trammel 

in Sweetwater Creek Basin, which have a combined capacity of about 105,000 acre-feet 

(revised). Many small diversions above station for municipal supply and oil-field 

operations.

Records available.- October 1923 to September 1949.

Average discharge.- 26 years, 1,631 second-feet.

.Extremes.- Maximum discharge during year, 96,200 second-feet May 17 (gage height, 26.7 

reet, from floodmark), from rating curve extended above 30,000 second-feet by logarithmic plotting; minimum, 81 second-feet Apr. 19.

1923-49: Maximum discharge, 97,600 second-feet May 18, 1935 (gage height, 23.68 

feet), from rating curve extended above 68,000 second-feet; no flow at times prior to 

construction of Possum Kingdom Dam.

Maximum stage known, about 30.0 feet May 8 or 9, 1922, from information by local 

residents.

Remarks.- Records good except those for May 17, 18, which are poor. Flow partly regulated by Possum Kingdom Reservoir (see p. 94) and several smaller reservoirs in Clear 

Pork Basin (see p.111). Many small diversions above station for irrigation, municipal 

supply, and oil-field operation.

Revisions (water years).- W 1058: 1932.

ao BRAZOS RIVER BASIN

Brazos River at Waco, Tex.

Location.- Water-stage recorder, lat. 31°33'40", long. 97°07'45", at Washington Avenue 

Bridge in Waco, McLennan County, 2| miles downstream from Bosq le River. Datum of gage 

is 356,80 feet above mean sea level, datum of 1929, supplementary adjustment of 1942.

Drainage area.- 28,500 square miles, of which 9,240 square miles is probably noncontributing.

Records available.- September 1898 to September 1949. (January 1912 to September 1914, 

monthly"records only, on Water-Supply Paoer 850). U. S. Weather Bureau has collected 

gage-height records in this vicinity since 1900.

Average discharge.- 51 years, 2,683 second-feet.

Extremes.- Maximum discharge during year, 71,400 second-reet May 18 (gage height, 27.27 

I'eet J; minimum, 82 second-feet Oct. 22.

1898-1949: Maximum discharge, 246,000 second-feet Sept. 27, 1936 (gage height, 40.90 

feet, levee on left bank was overtopped and broken by flood); minimum discharge for 

periods of daily record, 1898-1911, 1914-49, no flow Aug. 20, 21, 1918, and probably for 

several days in August 1923.

Maximum stage, 1854-97, 34.2 feet May 28, 1885. A stage of 39.7 feet was reached Dec. 

3, 1913, when levee on left bank was broken by flood, from information by U. S. Weather 

Bureau.

Remarks.- Records good except those below 200 second-feet which are fair. Flow partly 

regulated by Possum Kingdom Reservoir on Brazos River (see p. 94), several small reservoirs in Clear Fork Basin, and Lake Waco (capacity, 22,000 acre-feet) on Bosque River 

near Waco. A siltation survey of Lake Waco by the Soil Conservation Service of the U. S. 

Department of Agriculture in December 1947 indicates a 44.07 percent capacity loss from 

siltation since storage began in April 1930. Many small diversions above station for 

municipal supply, irrigation, and oil-field operation do not appreciably affect flow.

Revisions (water years).- W 850 and W 878: (monthly and yearly summaries only, 1899-1905,

Records available.- October 1938 to September 1949. 

Average discharge.- 11 years, 3,191 second-feet.

Extremes.- Maximum discharge during year, 61,600 second-feet May 19 (gage height, 22.9 

reet, from floodmark); minimum daily, 118 second-feet Oct. 23.

1938-49: Maximum discharge, 132,000 second-feet May 3, 1944 (gage height, 33.3 feet, 

from floodmark); minimum not determined.

Maximum stage known, 35.8 feet Dec. 3 or 4, 1913, from information by local residents. Flood of Sept. 28, 1936, reached a stage of 35.2 feet.

Remarks.- Records poor. Gage read twice daily, oftener during high stages. Plow partly 

regulated by reservoirs above Waco. Many small diversions, above station for Irrigation, 

municipal supply, and oil-field operation do not appreciably affect flow.

a Ho gage-height record; discharge computed on basis of records for stations near Whitney, at Waco, 

and near Bryan.

Hote.- Doubtful gage-height record Oct. 28-31, Nov. 2, 10, 12-14, 17-26, 28, Dec. 2, 7-10, Jan. 

30, Feb. 1; discharge computed on basis of records for stations near Whitney, at Waco, and near 

Bryan.
100 BRAZOS RIVER BASIN

Brazos River near Bryan, Tex.

Location.- Water-stage recorder, lat. 30 0 37', long. 96°29', 8.4 miles downstream from 

Little Brazos River and 9 miles southwest of Bryan, Brazos County. Datum of gage is 

192.3 feet above mean sea level, datum of 1929.

Drainage area.- 38,430 square miles, of which 9,240 square miles is probably noncontributing.

Records available.- September 1925 to September 1949. February 1918 to September 1925 at 

site near uoiiege Station, 7f miles downstream. August 1899 to December 1902 at site 

near College Station, ?J miles downstream, daily records published in U. S. Department of 

Agriculture, Office of Experiment Stations, Bulletins Nos. 104, 119, and 133.

Average discharge.- 30 years (1918-25, 1926-49), 5,968 second-feet.

Extremes.- Maximum discharge during year, 53,200 second-feet May 20 (gage height, 24.98 

reet); minimum, 221 second-feet Nov. 8.

1925-49: Maximum gage height, 46.1 May 20, 1930, present site and datum (discharge 

not determined); minimum discharge, 87 second-feet Aug. 24, 1934.

Maximum stage known, about 54.0 feet Dec. 5, 1913, present datum.

Remarks.- Records good except those for periods of no gage-height record, which are fair, 

flow partly regulated by reservoirs above Waco. Many small diversion? above station for 

irrigation, municipal supply, and oil-field operation do not appreciably affect flow.

Discharge, In second-feet, water year October 1948 to September 1949

Location.- Wire-weight gage, lat. 30°07'25", long. 96°11'00", at bridge on U. S. Highway 

 2yu, 4,500 feet upstream from Texas & New Orleans Railroad bridge, G.5 miles northwest

of Hempstead, Waller County, and 8 miles upstream from Caney Creek. Datum of gage is

117.99 feet (revised) above mean sea level, datum of 1929.

Drainage area.- 42,670 square miles, of which 9,240 square miles is probably noncontribut ing.

Records available.- October 1938 to September 1949. U. S. Weather Bureau has -collected 

gage-neiglTC records in this vicinity at intermittent periods since 1903.

Average discharge.- 11 years (1938-49), 8,169 second-feet.

Extremes.- Maximum discharge during year, 52,000 second-feet Apr. 29; maximum gage height, 

27.ia feet, from graph based on gage readings; minimum discharge, 324 second-feet 

Nov. 11 (computed from graph based on gage readings).

1938-49: Maximum discharge, 116,000 second-feet Nov. 30, 1940 (gage height, 44.04 

feet); minimum, 254 second-feet Nov. 8, 1939.

Maximum stage known, 56.1 feet Dec. 8, 1913, from data by engineers of Texas & New 

Orleans Railroad, obtained at bridge 4,500 feet downstream.

Remarks.- Records good. Flow partly regulated by reservoirs above Waco. Gage read twice 

dally, oftener during high stages. Many small diversions above station for irrigation, 

municipal supply, and oil-field operation do not appreciably affect flow.

108 BRAZOS RIVER BASIN 

Clear Pork Brazos River at Nugent, Tex.

Location.- Water-stage recorder, lat. 32°41', long. 99°40', at county highway bridge in 

nagent, Jones County, 4 miles upstream from Deadman Creek.

Drainage area.- 2,220 square miles

Records available.- February 1924 to September 1949.

Average discharge.- 25 years, 146 second-feet.

Extremes.- Maximum discharge during year, 3,120 second-feet Oct. 11 (gage height, 9.02 

reet); no flow at times.

1924-49: Maximum discharge observed, 47,000 second-feet Sept. 8, 1932 (gage height, 

27.05 feet, site then in use), from rating curve extended above 25,000 second-feet; no 

flow at times.

Maximum stage known, about 30.0 feet in 1876. from information by local residents.

Remarks.- Records good. Plow partly regulated by reservoirs in Elm Creek Basin (see p. Ill) 

ana Lakes Sweetwater and Trammel in Sweetwater Creek Basin, which have a combined 

capacity of about 105,000 acre-feet (revised). Diversions above station for municipal 

supply and oil-field operation materially affect low flow. Records of chemical analyses 

and water temperatures for water year 1949 are given in Water-Supply Paper 1163.

height, 35.99 feet); no flow Aug. 6, 1925 (result of pumping).

Maximum stage known, 38.9 feet, present datum, Dec. 8, 1913, from information by local 

residents; below Wharton floodwater combined with floodwater of Brazos River. Flood of 

about July 12, 1869, reached about same height. Flood of June 20, 1935, reached a stage 

of 38.2 feet, present datum (discharge, 159,000 second-feet,' from rating curve extended 

above 145,000 second-feet), furnished by U. S. Weather Bureau. Flood of July 30, 1938, 

reached a stage of 37.4 feet, present datum, observed by Geological Survey engineers 

(discharge, 145,000 second-feet).

Remarks.- Records fair. Gage read twice daily. Diversions above station for irrigation 

ana municipal supply. Regulation same as that for Colorado River at Austin. Records of

Barton Springs at Austin, Tex.

Location.- Lat. 30°16', long. 97°46'. Springs issue from channel and along banks of Barton 

creek for a distance of 1,000 feet in Zilker Park at Austin, Travis County. The main 

spring is near right bank of creek 500 feet upstream from concrete dam forming swimming 

pool, 1,800 feet upstream from bridge on Austin-Bee Cave Highway, and 0.6 mile upstrea-i 

from mouth of Barton Creek.

Records available - October 1918 to September 1926 and October 1940 to September 1949. 

November 1894 to September 1918, October 1926 to September 1940, discharge published 

as miscellaneous measurements. Daily discharge record of Barton Creek at Austin, 

published for period April 1917 to September 1918, closely represents flow of Barton 

Springs. Summary of all discharge measurements prior to October 1937 is contained in 

Water-Supply Paper 850.

Extremes.- Maximum discharge measured during year, 63.7 second-feet Apr. 30; minimum 

measured, 18.1 second-feet Nov. 23.

1894-1949: Maximum discharge measured, 166 second-feet May 10, 1941; minimom 

measured, 12.1 second-feet Feb. 26, 1918.

Remarks.- Discharge measurements represent total flow of springs including Old Mill JJpring 

which is on right bank and about 1,000 feet downstream from main spring. Springs emerge 

from Edwards limestone in Balcones fault zone and respond to rainfall on Edwards 'Plateau. 

Water used for recreational purposes.

feet June 30, 1340 (outflow, 1,670 second-feet); no flow most of time.

Remarks ._- Records good. Records given herein represent flow into Buescher Lake. No runoff 

except during and immediately following precipitation. Discharge below gage height 

22.27 feet (spillway crest), determined from change in contents of lake; that above gage 

height 22.27 feet determined by algebraic summation of flow over spillway (computed from 

spillway curve) and change in contents of lake (computed from capacity curve and reduced 

to equivalent second-feet). There was no flow over spillway during year. No adjustments made for evaporation or seepage losses. Capacity of lake, 255 acre-feet. No diversion above station or from lake.

200 NUECES RIVER BASIN

Nueces River at Cotulla, Tex.

Location.- Wire-weight gage, lat. 28°26', long. 99°16', at bridge on U. S. Highway 81, at 

uotuiia, La Salle County, a third of a mile upstream from International-Great Northern 

Railroad bridge. Datum of gage is 368.08 feet above mean sea level, datum of 1929.

Drainage area.- 5,260 square miles.

Records available.- October 1923 to September 1949. July 1915 to June 1918 at site 4 miles 

upstream.u. s. Weather Bureau has collected gage heights in this vicinity during 1914- 

17 and since 1922.

Average discharge.- 26 years, 315 second-feet.

Extremes.- Maximum discharge during year, 17,200 second-feet Mar. 3 (gage height, 20.45 

reet, rrom floodmark); no flow at times.

1923-49: Maximum discharge, 82,600 second-feet June 18, 1935 (gage height, 32.4 

feet, from floodmarks), by slope-area method; no flow at times.

Remarks.-Records good. Gage read once daily. Part of flow of Nueces River and its headwater tributaries enters Edwards limestone in Balcones fault zone which crosses basin 

just north of Uvalde. At low stages most of headwater flow enters this formation. Lowwater flow partly regulated by small storage reservoirs above station; most of it is 

diverted above station by pumping.

Cooperation.- Gage-height record furnished by U. S. Weather Bureau. 

Revision.- VJ 568: Drainage area.

Location.- Water-stage recorder, lat. 28°26'10". long. 98°11'10", 100 feet downstream from 

san Antonio, Uvalde & Gulf (Missouri Pacific) Railroad bridge, half a mile downstream 

from Frio River, and 2 miles southeast of Three Rivers, Live Oak-County. Datum of gage 

is 101.16 feet above msan sea level, datum of 1929.

Drainage area.- 15,600 square miles.

uecords available.- July 1915 to September 1949. U. S. V/eather Bureau has collected gageneisnt records in this vicinity since 1922.'

Average discharge.- 32 years (1915-18, 1920-49), 832 second-feet.

Extremes^- Maximum discharge during year, 22,000 seoond-feet Apr. 27 (gage height, 38.97 

feetJT minimum, 0.4 second-foot Oct. 15-17.

1915-49: Maximum discharge observed, 85,000 second-feet Sept. 18, 1919 (gage height, 

46.0 feet), from rating curve extended above 55,000 second-feet; no flow at times.

Remarks.- Records good. Part of flow 'of Nueces and Frio Rivers and their headwater trlbutaries enters Edwards limestone in Balcones fault zone which crosses'basin just north 

of Uvalde. At low stages most of headwater flow enters this formation. Diversions

Location.- Wire-weight gage, lat. 28°03', long. 97°52', at Mathis Dam on Nueces River, 

O.Y5 mile upstream from Texas & New Orleans Railroad bridge, 0.8 mile upstream from 

bridge on U. S. Highway 96, and 4 miles southwest of Mathis, San Patricio County. 

Datum of gage is 0.52 foot above mean sea level, datum of 1929.

Drainage area.- 16,660 square miles.

Records available.- September 1948 to September 1949. The Soil Conservation Service, 

U. b. Department of Agriculture, in cooperation with State Board of Water Engineers, 

has collected fragmentary gage-height records in connection with sedimentation studies 

since February 1942.

Extremes.- Maximum contents observed during year, 57,000 acre-feet Apr. 30 (gage height, 

Vv.Ub feet); minimum observed, 29,800 acre-feet Feb. 13-18, 25.

Remarks.- Reservoir is formed by a rolled-fill earthen-type dam containing an unregulated 

concrete service spillway 1,048 feet long, and five taintor gates, each 35 feet wide. 

Dam complete and storage began July 24, 1934. Capacity, 39,400 acre-feet at gage 

height 74 feet (top of taintor gates and service spillway). Dead storage is negligible. Reservoir used for municipal supply for city of Corpus Christ!. Water for city 

is released through sluice gate at gage height 43 feet. Figures given herein represent total storage. A siltatlon survey made by the Soil Conservation Service, U. S. 

Department of Agriculture, found the original capacity of reservoir to have been 

54,000 acre-feet, and capacity as of March 1942 as 43,400 acre-feet at spillway crest. 

A resurvey by that agency completed Mar. 31, 1948, found the capacity to be 39,400 

acre-feet at spillway crest.

Cooperation.- Capacity curve furnished by Soil Conservation Service, U. S. Department of 

Agriculture. Records of daily gage heights furnished by city of Corpus Christ!.

RIO GRANDE BASIN 229

Rio Grande near Bernardo, N. Mex.

Location.- Water-stage recorder, lat. 34°25'00", long. 106°47'50", in W^NW^ sec. 12, T.

N. , K. 1 E. (projected), at bridge on U. S. Highway 60, 2£ miles east of Bernardo and 

miles upstream from Rio Puerco. Auxiliary water-stage recorders on San Francisco 

riverside drain and Bernardo interior drain, each at different datum used during periods 

of overflow or levee breads.

Drainage area.- 19,230 square miles (includes 2,940 square miles in closed basin in 

nortnern part of San Luis Valley, Colo.).

Records available.- June 1936 to January 1939, October 1941 to September 1949. «

Extremes.- Maximum daily discharge during year, 9,810 second-feet June 24 (composite flow 

or a channels) ; minimum daily, 28 second-feet Oct. 25.

1936-39, 1941-49: Maximum discharge not determined, probably occurred Apr. 25, 1942; 

maximum daily discharge, 19,600 second-feet Apr. 25, 1942; minimum gage height, 6.90 

feet Apr. 25, 1942; minimum daily discharge, 8 second-feet Aug. 21, Sept. 29, 1946.

Remarks.- Records fair excepc those for periods of no gage-height record, which are poor. 

Kecords represent total discharge of river and are a summation of the discharge in the 

channels that carry river water. Many diversions above station for irrigation. Records of suspended sediment loads for water year 1949 are given in Water-Supply Paper 

1163.

Principal diversions from Rio Lucero, N. Hex.

Records of discharge are collected for five ditches that divert water from the Rio 

Lucero below gaging station on that stream near Arroyo Seco. Each of these ditches is 

equipped with a water-stage recorder for collecting gage-height records. Water diverted 

by these ditches is used for irrigation in the valley of Rio Lucero below gaging station 

near Arroyo Seco.

Tenorlo ditch diverts from right bank in sec. 10, T. 26 N., R. 13 E. (projected), 200 feet 

downstream from gaging station on Rio Lucero near Arroyo Seco. Records available, June 

1935 to September 1949 (irrigation seasons only).

between Nambe diversion dam, 2| miles upstream from Nambe, and confluence with Rio 

 Tesuque. Each of these ditches is equipped with a water-stage recorder for collecting 

gage-height records and each one, except Las Joyas, with a Parshall flume. Water-diverted 

by these ditches is used for irrigation in the valley of Nambe Creek, except that diverted 

by Jacona ditch, which is used for irrigation on the left bank of Rio Pojoaque below Rio 

Tesuque.

328 RIO GRAMDE BASIN 

Pecos River near Lake Arthur, N. Mex.

Location.- Water-stage recorder, lafc. 32 0 59'25", long. 104°19'10", on line between sees. 

2b ana 27, T. 15 S., R. 26 E., 1,100 feet upstream from highway bridge, 3 miles east of 

Lake Arthur, 10 miles upstream from Cottonwood Creek, and 11 miles northeast of Artesia.

Drainage area.- 14,760 square miles (contributing area). 

Records available.- August 1938 to September 1949. 

Average discharge.- 11 years (1938-49), 391 second-feet.

Extremes.- Maximum discharge during year, 12,700 second-feet July 15 (gage height, 12.7 

reet, from floodmarks); minimum daily, 6.9 second-feet Mar. 31.

1938-49: Maximum discharge, 49,600 second-feet Sept. 24, 1941 (gage height, 21.90 

feet), from rating curve extended above 16,100 second-feet on basis of slope-area 

determinations at gage height 21.77 feet and logarithmic plotting; no flow Aug. 21, 22, 

1947.

Flood of May 30, 1937, reached a stage of 21.77 feet (discharge, 51,500 second-feet, 

by slope-area method), but may have been exceeded by floods of 1904 and 1919.

Remarks.- Records good except those for periods of ice effect or no gage-height record, 

which are fair. Diversions above station for irrigation. Flow partly regulated by 

Alamogordo Reservoir, 150 miles above station (see p. 235).

RIO GRANDE BASIN 329

Pecos River near Artesia, N. Mex.

Location.- Water-stage recorder, lat. 32°50'05", long. 104°19 I 25", in W^NWi sec. 18, T. 

iv S., R. 27 E., at bridge on Artesia-Lovington highway, 4.3 miles east of Artesia, 

7.0 miles north Of mouth of Rio Penasco, and 17 miles north of McMillan Dam.

Drainage area.- 15,300 square miles (contributing area).

Keeords available.- March 1905 to September 1925, October 1931 to February 1936 (published 

as fecos Kiver near Dayton), and February 1936 to. September 1949 in reports of Geological Survey. March 1905 to December 1931 in reports of State engineer.

Average discharge.- 13 years (1936-49), 431 second-feet.

Extremes.- Maximum discharge during year, 5,550 second-feet July 16 (gage height, 12.01 

reet); minimum daily, 5.4 second-feet Apr. 2.

1905-49: Maximum gage height, 15.9 feet Sept. 18, 1919, site and datum then in use 

(discharge not determined). Flood of May 30, 1937, reached a gage height of 14.7 feet 

(discharge, 51,500 second-feet, by slope-area method); no flow Aug. 17-24, 1934, Aug. 

14-25, 1946, Aug. 1-22, 1947.

Remarks.- Records good except those for periods of ice effect or no gage-height record, 

and those for Aug. 10-20, which are poor. Diversions above station for irrigation. 

Flow partly regulated by Alamogordo Reservoir (see p. 235). Discharge represents inflow to Lake McMillan, which stores water for irrigation of about 25,000 acres of 

Carlsbad project. Records of chemical analyses, water temperatures, and suspended 

sediment loads for water year 1949 are given in Water-Supply Paper 1163.

21 b., R. 26 E., at dam site 3 of Carlsbad project of Bureau of Reclamation, about 1 

miles upstream from flow line of Lake Avalon, 1.3 miles downstream from Rocky Arroyo, 

and 8 miles northwest of Carlsbad. Datum of gage is 3,172.31 feet above mean sea level 

(Bureau of Reclamation datum).

Drainage area.- 17,620 square miles (contributing area).

Records available.- August 1939 to December 1940, August 1944 to September 1949.

Extremes.- Maximum discharge during year, 6,100 second-feet July 13 (gage height, 6.60 

reet;, from rating curve extended above 2,200 second-feet by logarithmic plotting; 

minimum daily, 27 second-feet Apr. 7.

1939-40; 1944-49: Maximum discharge, 18,200 second-feet May 31, 1948 (gage height, 

12.3 feet); minimum daily, 16 second-feet June 18-21, 1946, Oct. 11, 1947.

Flood of Oct. 2, 1904, was estimated at 82,000 second-feet at McMillan Dam (about 

10 miles upstream) by chief engineer of Pecos River Irrigation Co.

Remarks.- Records good except those for periods of no gage-height record and those above 

1,000 second-feet, which are poor. Flow regulated by storage in Alamogordo Reservoir 

and Lake McMillan (see p. 235). Many diversions above station for irrigation. Discharge represents inflow of Lake Avalon.

Principal diversions from Pecos River between Red Bluff Reservoir and Imperial, Tex.

Records of discharge are collected for eight canals that divert water from Pecos River 

between Red Bluff Reservoir and Imperial,,Tex. Each of these canals is equipped with a 

water-stage recorder for collecting gage-height records. All stations are located within 

2 miles of canal head gate except as noted herein. Water diverted by these canals is 

used for irrigation of lands on both sides of Pecos River in Reeves, Ward, and Pecos 

Counties. Stations prior to 1941 were published separately (daily discharge figures for 

the earlier records). Gage-height records collected in cooperation with Red Bluff Water 

Power Control District, Pecos, Tex.

Las Moras Springs at Brackettville, Tex.

Location.- Lat. 290 18', long. 100°25', at Brackettville> Kinney County, a quarter of a 

mile upstream from bridge on Brackettville-Fort Clark road.

Records available.- December 1895 to August 1938 (occasional miscellaneous discharge 

measurements), September 1938 to September 1949 (discharge measurements only).

Extremes.- 1895-1949: Maximum discharge measured, 60 second-feet (by Prof. T. U. Taylor) 

June ^0, 1899; minimum measured, 5.7 second-feet July 21, 1945.

Remarks.- Discharge measurements represent total flow of springs. Springs issue from

limestone in Balcones fault zone and respond to rainfall on Edwards Plateau. Elevation 

of spring pool is regulated by outlet gate which materially affects discharge. City of 

Brackettvills diverts water from spring pool1 for domestic and recreational uses.
