SCOPE OP WORK

This volume Is one of a series of 14 reports presenting results of measurements of 

stage and flow made on streams, lakes, and reservoirs In the United States during the 

water year ending September 30, 1950'. The work was begun In 1888 In connection with 

special studies relating to Irrigation. Measurements of the flow of streams and of the 

stage and contents of lakes and reservoirs have been made at about 12,060 gaging stations 

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

30, 1950, 6,54.0 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 gaging-statlon records in each volume. In the present 

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

DEFINITION OF 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 the 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 Tunorr 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 gallons and 

represents a runoff of 0.0372 Inch from 1 square mile.

"Stage-discharge relation" is an abbreviation for the term "relation between gage height 

and discharge."

"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.

"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.

.2 SURFACE WATER SUPPLY, 1950, PART 8

"Drainage area" of a stream at a specified location is that area, measured in a horizontal plane, which is enclosed by a topographic divide such that direct surface runoff from 

precipitation normally would drain by gravity into the river basin above the specified 

point. Figures of drainage area given herein include all closed basins or non-contributing 

areas within the area unless otherwise noted.

EXPLANATION OF 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 relat.ion 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 ^s 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 ie 

of no importance). Unlese otherwise qualified, the maximum discharge corresponds to the 

crest stage, obtained by use of a water-stage recorder, a crest-stage Indicator, or a nonre-cordlng 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 revlsipn of the drainage area necessitates corresponding.revision 

of all figures based on the drainage area. Revised figures of second-feet per square mile 

and runoff in Inches resulting from a revision of the drainage area only are usually not 

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 daily mean gage height may not 

indicate the true dally 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 

dally 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 dally discharge gives the discharge
ACCURACY OF FIELD DATA AND 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 daily 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 daily 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 daily 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 art 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 (2) 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 tnan IS percent; and 

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

and runoff are, in general, more accurate than the dally 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 reaervolr contents, unless its inclusion is indicated. Even at those stations 

where adjustments are made, in some instances large errors in computed yields may occur 

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 nonoontrlbuting areas or-lf 

the average annual rainfall over the drainage area is less than 20 inches.
6 SURFACE WATER SUPPLY, 1950, 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. x

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.

The records at most of the stations discussed in these reports extend over a series of 

years. Miscellaneous measurements at many points other than regular gaging stations have 

been made each year and are published under "Miscellaneous discharge measurements" at the 

end of each report, the streams and points of measurement listed appearing in the same 

relative order as the streams and gaging stations in the body of the report. An index of 

the records obtained prior to 1904 has been published In Water-Supply Paper 119.

Each of the reports on surface water supply for the year 1939, issued as Water-Supply 

Papers 871 to 884 (see table on p. 8), contains, for the area covered by that report, a 

sumaary of yearly discharge at gaging stations at which 10 or more complete years of record 

have been collected. These summaries are available also as separate reprints.

Reports have been published that are compilations of records for various areas, usually 

a single state or drainage basin. These reports contain records previously published 

(some of which have been revised), as well as some records not contained in the annual 

series of water-supply papers. The following table gives the numbers and titles of these 

reports, arranged alphabetically, some by States and some by drainage basins.

TRINITY RIVER BASIN 53

Trinity River at Dallas, Tex.

Location. Water-stage recorder, lat. 32°47', long. 96°48', at Commerce Street viaduct In

 Dallas, Dallas County, 5^'miles downstream from confluence of West and Elm Forks. Datum

of gage is 368.14 feet above mean sea level, datum of 1929. 

Drainage area.--6,120 square miles. 

Kecords available.--July 1903 to July 1930, October 1932 to September 1950 (January 1907

 to September 1920, monthly records only, in Water-Supply Paper 850). October 1898 to 

December 1899 (gage heights only) at site 2 miles upstream. July 1930 to September 

1932 at site 6 miles downstream. U. S. Weather Bureau has collected gage-height records 

in this vicinity since 1903.

Average discharge. 47 years (1903-50), 1,605 second-feet.

Extremes.--Maximum discharge during year, 28,800 second-feet May 4 (gage height, 38.10

 t'eet); minimum, 160 second-feet Oct. 17; minimum gage height, 12.48 feet Nov. 30.

1903-50: Maximum discharge, 184,000 second-feet May 25, 1908 (gage height, 52.6

feet), from rating curve extended above 109,000 second-feet; minimum observed for

periods 1903-6, 1920-50, 6.8 second-feet Sept. 11, 1924. 

Remarks. Records good except those for rapidly changing stage, which are fair. Flow

 partly regulated by Bridgeport, Eagle Mountain, Lake Worth, Mountain Creek, and Lake 

Dallas Reservoirs (combined capacity, 757,000 acre-feet). Cities of Fort Worth and 

Dallas divert water for municipal supply. During the current year city of Dallas 

diverted 56,600 acre-feet of water from the river above station and returned 38,900 

acre-feet of sewage effluent below station. Several small diversions on West Fork 

above Fort Worth.

minimum gage height observed, 4.95 feet Oct. 1.

1938-50: 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, present datum, was reached May 8-11, 1922, from observation 

by U. S. Weather Bureau at chain gage on railroad bridge upstream.

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

Heignt because tides affect stage-discharge relation. Flow partly regulated by reservoirs above Dallas.

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

SAN JACINTO RIVER BASIN 87

Barker Reservoir near Addlbks, Tex.

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

45 reet upstream from reservoir outlet works, 1,160 feet upstream from Addlcks-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 Clodlne, 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. ISO square miles at outlet works; 105 square miles at upper gage.

Hecoras available.--August 194S to September 1950.

Extremes. Maximum gage height at dam during year, 82.5 feet Oct. 9 (contents, 176 acrereet). This flood reached a stage of 96.5 feet on Oct. 8 at upper gage. Maximum gage 

height at upper gage, 96.9 feet June 6-8.

1945-50: 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

completed 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 acrefeet 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.

in Houston, Harris County, 0.41 mile upstream from Texas & New Orleans Railroad bridge, 

and 3.1 miles upstream from Whiteoak Bayou. Datum of gage Is 4.08 feet below mean sea 

level, datum of 1929.

Drainage area.--362 square miles.

Records available.--May 1936 to September 1950.

Average discharge.--14 years, 305 second-feet.

Extremes. Maximum discharge during year, 6,500 second-feet Oct. 8 (gage height, 27.85 

reet); minimum, 3.1 second-feet Aug. 17.

1936-50: Maximum discharge, 10,900 second-feet Aug. 30, 1945 (gage height, 34.23 

feet); minimum not determined.

Maximum stage known since 1935, 54-4 feet Dec. 9, 1935, present site and datum (discharge, 40,000 second-feet, furnished by engineer for Harris County). Flood of May 31, 

1929, reached a stage of 48.9 feet, present site and datum (discharge, 19,000 secondfeet at bridge on Capitol Avenue, 2 miles downstream, from rating curve extended above 

15,300 second-feet, stage-discharge relation materially affected by interference of 

bridge; furnished by city of Houston).

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

Flood flow partly regulated by Barker Reservoir (see p. 87) and Addicks Reservoir 

(see p. 90). Extreme low flow partly maintained by industrial waste water. No diversion above station

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

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

mouth. Auxiliary water-stage recorders: lat. 29"48'05^, long. 95°41i30" on South 

Mayde Creek at Groeschke Road bridge, 3.2 miles west of Addicks, 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. 29°50'10", long. 95°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 1950.

Extremes.--Maximum elevation at'dam during year, 90.5 feet Oct. 8, 9 (contents, 2,460 

acre-feet); maximum at gage on South Mayde Creek, 106.6 feet Oct. 8; maximum at gage 

on Langham Creek, 101.9 feet Oct. 8.

1948-50: Maximum elevation at dam, that of Oct. 8, 9, lr, 1 9; maximum at gage on 

South Mayde Creek, 106.8 feet Apr. 22, 1949; maximum at gage on Langham Creek, that

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

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 partly stored in reservoir. Elevations at 

auxiliary g. ges 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.

96 OYSTER CREEK BASIN

Oyster Creek near Angleton, Tex.

Location. Water-stage recorder, lat. 29°09'25", long. 95°28'35", at bridge on State Highway 35, 2-5- miles west of Angleton, Brazoria County, 4.0 miles upstream from Missouri 

Pacific Railroad bridge, 4j miles downstream from another Missouri Pacific Railroad 

bridge, and about 45 miles upstream from mouth at Gulf of Mexico. Datum of gage is 

1.31 feet below mean sea level, datum of 1929.

Records available.--October 1944 to September 1950.

Extremes.--Maximum discharge during year, 2,320 second-feet Oct. 12 (gage height, 28.92 

t'eet); minimum, 9.9 second-feet May 25.

1944-50: Maximum discharge, that of Oct. 12, 1949; minimum, 3.2 second-feet Nov. 21, 

1948.

Flood of December 1913 reached a stage of about 32 feet, from information by State 

Highway Department; flood of Dec. 5, 1940, reached a stage of 30.7 feet, from levels 

to floodmark on bridge to which gage is attached. At extreme high stages the Brazos 

River overflows into Oyster Creek above this station and there may be some relation 

between stage of Brazos River at East Columbia and stage at this station.

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

Diversions above station for irrigation. A large part of the low flow is water released 

from Harris Reservoir for industrial use below station. Harris Reservoir is supplied 

with water diverted from Brazos River during r>pi*ir>rts of flood flow.

BRAZOS RIVER BASIN 105

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, 2j miles downstream from Bosque 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 1950. (January 1912 to September 1914, 

montniy records only, in Water-Supply Paper 850.) U. S. Weather Bureau has collected 

gage-height records in this vicinity since 1900.

Average discharge. 52 years, 2,664 second-feet.

Extreme s.--Maximum discharge during year, 16,700 second-feet Peb. 13 (gage height, 15,67 

reet); minimum, 192 second-feet Apr. 13.

1898-1950: 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, 1914-50, 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. Plow partly regulated by Possum Kingdom Reservoir on Brazos River 

tsee" p. 101), several small reservoirs in Clear Pork 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,

19UY-1U).

Discharge, in second-feet, water year October 1949 to September I95o

Records available.--October 1938 to September 1950. 

Average discharge.--12 years, 3,082 second-feet.

Extremes. Maximum discharge during year, 19,200 second-feet Feb. 13 (gage height, 13.2 

reet, from floodmark); minimum daily, 262 second-feet Jan. 7.

1938-50: 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 fair. Gage read twice daily, oftener during high stages. Flow partly 

regulated by reservoirs above Waco. Many small diversions above- station for irrigation, municipal supply, and oil-field operation do not appreciably affect flow.

108 BRAZOS RIVER BASIN

Brazos River near Hempstead, Tex.

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

290, 4,500 feet upstream from Texas & New Orleans Railroad bridge, 6.5 miles northwest 

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

117.99 feet above mean sea level, datum of 1929, Houston supplementary adjustment of 

1943.

Drainage area. 42,670 square miles, of which 9,240 square miles is probably noncontributlng.

Records available.--October 1938 to September 1950. U. S. Weather Bureau has collected 

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

Average discharge.--12 years (1938-50), 7,955 second-feet.

Extremes. Maximum discharge during year, 49,400 second-feet Feb. 14; maximum gage height, 

iib.au feet Feb. 15, from graph based on gage readings; minimum discharge, 750 secondfeet Dec. 1 (computed from graph based on gage readings).

1938-50: 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. Gage read twice daily, oftener during high stages. Flow partly 

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

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

Records available. July 2-6, 1940 (in Water-Supply Paper 1046), April 1948 to September

 19bl). u. s. weather Bureau has collected gage-height records in this vicinity since 

1946.

Extremes. Maximum discharge during year, 24,800 second-feet June 4.(gage height, 30.51

 i'eet); minimum daily, 137 second-feet July 29.

1940, 1948-50: Maximum discharge, 83,300 second-feet July 4, 1940 (gage height, 48.2 

feet, present datum) at bridge on State Highway 35, observed by Corps of Engineers 

(stage, 46.6 feet, adjusted to present site); minimum daily, 16 second-feet June 5. 

1948.

Maximum stage known, about 56.1 feet Dec. 10, 1913. Flood of July 1869 probably 

reached about same stage. Stages of other floods as follows: May 8, 1922, 55.4 feet; 

June 1929, 55.0 feet; June 22, 1935, 54.6 feet; Oct. 5, 1936, 53.4 feet; Aug. 2, 1938, 

53.4 feet; Nov. 27, 1940, 47.6 feet. All above flood data from information by Texas 

& New Orleans Railroad and adjusted to present gage site.

Remarks. Records good except those below 300 second-feet and those for periods of no

 gage-height record, which are poor. Many diversions above gage for municipal and irrigation uses. Regulation same as that for Colorado River at Austin.

Discharge, In second-feet, water year October 1949 to September 195O

RIO GRANDE BASIN 

Principal diversions from Pecos River between Rod 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.

County Water Improvement District No. 1, in eastern outskirts of Port Stockton, Pecos 

County, a quarter of a mile upstream from bridge on U. S. Highway 290 and 0.5 mile 

downstream from head of springs. Datum of gage is 2,922.8 feet above mean sea level, 

datum of 1929.

Records available. February 1941 to September 1950. 1899, 1904, 1919, 1922, 1924-25. 

iyaa-41 (occasional discharge measurements published as miscellaneous measurements).

Extremes. Maximum daily discharge during year, 38 second-feet Jan. 2 to Mar. 11; minimum 

aally, 30 second-feet June 23 to Sept. 29.

1941-50: Maximum daily discharge, 54 second-feet Jan. 30, 1942: minimum daily, that 

of June 23 to Sept. 29, 1950.

Maximum discharge measured prior to 1941, 66 second-feet June 23, 1899; minimum 

measured, 38.7 secondrfeet July 14, 1936.

Remarks.--Records good. Discharge represents total flow of springs exclusive of surface 

runoff from precipitation. Spring flow fluctuates slowly and aquatic growth changes 

stage-discharge relation frequently; daily discharge determined from hydrograph based 

on discharge measurements. About 6,000 acres of land irrigated below station.

Las Moras Springs at Brackettville, Tex.

Location.--Lat. 29°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 1950 (discharge measurements only), discontinued.

Extremes.--1895-1950: Maximum discharge measured, 60 second-feet (by Prof. T. U. Taylor) 

June 30, 1899; minimum measured, 5.7 second-feet July 21, 1945.

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

limestone in the 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 Brackettville diverts water from spring pool for domestic and recreational 

uses.
