SURFACE WATER SUPPLY OF THE SOUTH ATLANTIC

COAST AND EASTERN GULF OF MEXICO

BASINS, 1912.

By W. E. HALL and C. H. PIERCE.

AUTHORIZATION AND SCOPE OF WORK.

This volume is one of a series of twelve reports presenting results 

of measurements of flow made on streams in the United States 

during the calendar year 1912.

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 

Burvey 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 sundry civil bills passed by Congress have carried 

the following item and appropriations:

For gaging the streams and determining the water supply of the United States, 

and for the investigation of underground currents and artesian wells, and for the 

preparation of reports upon the best methods of utilizing the water resources. 

Annual appropriations for the fiscal year ending June 30 

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

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

1897 to 1900,inclusive................................... 50,000

1901 to 1902,inclusive................................... 100,000

1903 to 1906, inclusive................................... 200,000

1907..................................................... 150,000

1908 to 1910,inclusive.-................................. 100,000

1911 to 1913,inclusive................................... 150,000

In the execution of the work many private and State organizations 

have cooperated, either by furnishing data or by assisting in collecting 

data. Acknowledgments for cooperation of the first kind are made 

in connection with the description of each station affected, and of 

the second kind on page 14.

Measurements of stream flow have been made at about 2,000 points 

in the United States and also at many points in small areas in Seward

Peninsula and the Yukon-Tanana region, Alaska, and in the Hawaiian 

Islands. During 1912 gaging stations were maintained by the 

Survey and the cooperating organizations at about 1,500 points, 

and many 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 regular water supply papers from time to time.

PUBLICATIONS. 

A report has been prepared for each calendar year embodying the 

steam-flow data collected during that year. An index to the reports 

containing stream-flow measurements prior to 1904 has been published as Water-Supply Paper 119. Circulars are also available 

giving complete lists of the gaging stations maintained by the Survey 

to date, and a list of the reports relating to the water supply of the 

country.

Prior to 1902 gage heights and discharge measurements were 

published in water-supply papers or bulletins and estimates of 

monthly discharge in annual reports; since 1902 both classes of 

data have been published in water-supply papers and they are now 

being published in twelve parts, as shown in the following table:

DEFINITION OF TERMS.

The volume of water flowing in a stream the "run-off" or "discharge" is expressed in various terms, each of which has become 

associated with a certain class of work. These terms may be divided 

into two groups (1) those which represent a rate of flow, as secondfeet, gallons per minute, miner's inches, and discharge in second-feet 

per square mile, and (2) those which represent the actual quantity 

of water, as run-off in depth in inches, and acre-feet. The units used 

in this series of reports are second-feet, second-feet per square mile, 

run-off in depth in inches, and acre-feet. They may be denned as 

follows:

"Second-foot" is an abbreviation for cubic foot per second and is 

the unit for the rate of discharge of water flowing in a stream 1 foot 

wide, 1 foot deep, at a rate of 1 foot a second. It is generally used as 

a fundamental unit from which others are computed by the use of the 

factors given in the following table of equivalents.
10 SURFACE WATER SUPPLY, 1912, PART II.

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

of water flowing per second from each square mile of area drained, 

on the assumption that the run-off is distributed uniformly both as 

regards time and area.

"Run-off, depth in inches," is the depth to which the drainage 

area would be covered if all the water flowing from it in a given 

period were conserved and 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" is equivalent to 43,560 cubic feet, and 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.

CONVENIENT EQUIVALENTS.

EXPLANATION OF DATA.

For each regular current-meter gaging station the following data, 

so far as available, are given: Description of the station, list of discharge measurements, table of daily gage heights, table of daily discharge, table of monthly and yearly discharge and run-off. For 

stations located at weirs or dams the gage-height table is omitted.

In addition to statements regarding the location and installation 

of current-meter stations, the descriptions give information in regard 

to any conditions which may affect the constancy of the relation of 

gage height to discharge, covering such points as ice, logging, shifting
12 STJBFACE WATEB SUPPLY, 1912, PABT H,

channels, and backwater; also information regarding diversions 

which decrease the total flow at the measuring section. Statements 

are also made regarding the accuracy and reliability of the data.

The table of daily gage heights records the daily fluctuations of the 

surface of the river as found from the mean of the gage readings taken 

each day, usually in the morning and in the evening. The gage height 

given in the table represents the elevation of the surface of the water 

above the zero of the gage. All gage heights affected by the presence 

of ice in the streams or by backwater from obstructions are published 

as recorded, with suitable footnotes. The rating table is not applicable for such periods unless the proper corrections to the gage 

heights are known and applied. Attention is called to the fact that 

the zero of the gage is placed at an arbitrary datum and has no relation to zero flow or the bottom of the river. In general the zero is 

located somewhat below the lowest known flow, so that negative 

readings shall not occur.

The discharge measurements and gage heights are the base data 

from which rating tables, daily discharge tables, and monthly discharge tables are computed.

The rating table gives, either directly or by interpolation, the 

discharge in second-feet corresponding to every stage of the river 

recorded during the period for which it is applicable. It is not published in this report, but can be determined from the tables of daily 

gage heights and daily discharge by plotting gage heights in feet 'as 

ordinates and discharge in second-feet as abscissas.

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

corresponding to the observed gage heights as determined from the 

rating tables.

In the table of monthly discharge the column headed "Maximum" 

gives the mean flow, as determined from the rating table, for the 

day when the mean gage height was highest. As the gage height is 

the mean for the day, it does not indicate correctly the stage when 

the water surface was at crest height and the corresponding discharge 

was consequently larger than given in the maximum column. Likewise in the column at "Minimum" the quantity given is the mean 

flow for the day when the mean gage height was lowest. The column 

headed "Mean" is the average flow in cubic feet for each second during the month. On this the computations for the remaining columns, 

which are defined on pages 9 and 10, are based.

The base data presented in this report, unless otherwise stated in 

description of station, nave been collected by the methods commonly 

used at current-meter gaging stations and described in standard 

text books.

ACCTTBACY AND RELIABILITY OF FIELD DATA AND 

COMPARATIVE RESULTS.

The accuracy of stream-flow data depends primarily on the 

natural conditions at the gaging station and on the methods and 

care with which the data are collected. Errors of the first group 

depend on the degree of permanency of channel and of permanency of 

the relation between discharge and stage.

Errors of the second class are due, first, to errors in observation of 

stage; second, to errors in measurements of flow; and, third, to 

errors due to misinterpretation of stage and flow data.

In order to give engineers and others information regarding the 

probable accuracy of the computed results, footnotes are added to the 

daily discharge tables, stating the probable accuracy of the rating 

tables used, and an accuracy column is inserted in the monthly discharge table. For the rating tables, "well defined" indicates, in general, that the rating is probably accurate within 5 per cent; "fairly 

well defined," within 10 per cent; "poorly defined" or "approximate," within 15 to 25 per cent. These notes are very general and 

are based on the plotting of the individual measurements with reference to the mean rating curve.

The accuracy column in the monthly discharge table does not 

apply to the maximum or minimum nor to any individual day, but to 

the monthly mean. It is based on the accuracy of the rating, the 

probable reliability of the observer, and knowledge of local conditions, 

In this column, A indicates that the mean monthly flow is probably 

accurate within 5 per cent; B, within 10 per cent; C, within 15 per 

cent; D, within 25 per cent. Special conditions are covered by footnotes.

Even though the monthly means for any station may represent 

with a high degree of accuracy the quantity of water flowing past the 

gage, the figuies showing discharge per square mile and depth of runoff in inches may be subject to gross errors which result from including in the measured drainage area large noncontributing districts or 

omitting estimates of water diverted for irrigation or other use, and 

they should, therefore, be considered as only approximate, particularly for periods of irrigation or of low water. For these errors it is 

as a rule not feasible to make adequate correction.

In general, the base data collected each year by the Survey engineers are published, not only to comply with the law, but also to 

afford any engineer the means of examining and adjusting to his own 

needs the results of the computations. The table of monthly discharge is so arranged as to give only a general idea of the flow at the 

station and should not be used for other than preliminary estimates. 

The determinations of daily discharge allow more detailed studies of
14 SUBFACE WATER SUPPLY, 1912, PART II.

the variation in flow by which the period of deficiency may be determined.

It should be-borne in mind that the observations in each succeeding 

year may be expected to throw new light on data already collected 

and published, and the engineer who makes use of the figures presented in these papers should verify all ratings and make such adjustments for earlier years as may seem necessary.

JAMES RIVER BASIN.

JAMES RIVER AT BUCHANAN, VA.

Location. At the highway bridge near the Chesapeake & Ohio Eailway depot at 

Buchanan, Va.

Records available. August 18, 1895, to December 31, 1912.

Drainage area. 2,060 squtre miles.

Gage. A chain gage, attached to the highway bridge, was installed November 21, 

1903, to replace the original wire gage read from August 18, 1895, to that date. 

The datum of the gage was lowered 2 feet April 3, 1897, to avoid negative readings; subsequently the datum of the gage has remained constant.

Channel. The bed of the river under the bridge is composed of rock overlain with 

a deep deposit of mud. There is a rock control several hundred feet below the 

station.

Discharge measurements. Made from the downstream side of two-span highway 

bridge.

Winter flow. Occasionally affected by ice for short periods.

Accuracy. Bating curve well developed. Published data considered good. 

Cooperation. Previous to July 15, 1906, the observations of daily gage height were 

made by employees of the Geological Survey; since that time gage height records 

have been furnished by the United States Weather Bureau.

The following discharge measurement was made by Jackson and Batchelder. 

November 21, 1912, gage height, 2.21 feet; discharge, 560 second-feet.

JAMES RIVEE AT CAETEESVILLE, VA.

Location. At the highway bridge crossing James River between Pemberton and

Cartersville, about 50 miles above Richmond. 

Records available. January 1, 1899, to December 31, 1912. 

Drainage area. 6,230 square miles. 

Gage. A standard chain gage was attached to the highway bridge July 24, 1903, to

replace the wire gage which had been used from January 1, 1899, to that date.

The datum of the gage has remained the same since the station was established. 

Channel. The left bank overflows for several hundred feet at a stage of about 20

feet. The right bank does not overflow. 

Discharge measurements. Made from downstream side of six-span highway

bridge.

Winter flow. Occasionally affected by ice for short periods during severe winters. 

Accuracy. Rating curve well developed for ordinary stages. Above the overflow

point the discharge is uncertain.

Discharge measurements of James River at Cartersville, Fa., in 1912.

ROANOKE RIVER BASIN.

ROANOKE RIVER AT ROANOKE, VA.

Location. At the Walnut Street highway bridge at Roanoke, Va

Records available. July 10, 1896, to July 14, 1906; May 7, 1908, to December 31,

1912.

Drainage area. 388 square miles. 

Gage. A standard chain gage was attached to the Walnut Street Bridge November

28, 1903, to replace the wire gage which had been read from July 10, 1896, to that

date. The datum of the gage has remained unchanged since the station was

established. 

Channel. Nearly straight, 160 feet wide between bridge abutments; broken by one

pier. The bed of the stream is composed of coarse gravel and small bowlders.

The right bank is above high water but the left bank may overflow at extreme

flood stages. 

Discharge measurements. Made from the downstream side of two-span highway

bridge.

Winter flow. Occasionally affected by ice for short periods. 

Accuracy. Owing to varying conditions of flow frequent measurements are required

at low stages to adequately define the discharge curve from year to year. 

Cooperation. Gage-height records furnished through the courtesy of the Roanoke

Railway & Electric Co., J. W. Hancock, general manager.

ROANOKE RIVER AT OLD GASTON, N. C.

Location. At railroad bridge of Roanoke Railway Co. at Old Gaston, N. C., 1J 

miles north of Thelma, N. C., about three-fourths of a mile below mouth of Indian 

Creek and 2J miles above mouth of Deep Creek.

Records available. December 7, 1911, to December 31, 1912.

Drainage area. Not measured.

Gage. Standard chain gage attached to outside of guard timber on downstream side 

of second span from right end of decked plate girder railroad bridge of Roanoke 

Railway Co.

Channel. Fairly permanent. Point of control, about 1 mile below, is of rock and 

probably permanent.

Discharge measurements. Made from downstream side of bridge to which gage 

is attached. Measuring section broken by 11 bridge piers.

Floods. Flood of 1877 highest known in this locality. No definite marks preserved 

at Old Gaston, but from authentic information regarding the "crest height as 

obseryed in 1877* the approximate height has been determined as about 19 feet, 

refer/ed to present gage datum. The corresponding discharge is about 275,000 

second-feet. The crest height of the flood of March, 1912, is shown in Plate III.

Winter flow. Ice sometimes forms to considerable thickness at this station.

Artificial control. It has been stated by those engaged in the operation of power 

plants at Roanoke Rapids and Weldon that a weekly trough has been noticed to 

occur on Tuesday or Wednesday during periods of low water. Such troughs 

have been said to be due probably to the weekly shut down of large power plants 

farther upstream.

Accuracy. Gage observer considered reliable. The gage being situated about 1 

mile from' the lower end of a pool approximately 3 miles long, the station is not 

very sensitive. The left bank overflows in extreme floods but a fair determination can be made of the overflow discharge around the bridge.

Discharge measurements of Roanoke River at Old Gaston, N. C., in 1912.

ROANOKE RIVER AT WELDON3 N. C.

General statement. The Geological Survey entered into a study of this United 

States Weather Bureau station to ascertain whether or not a record of discharge 

could be obtained from the gage record for back years. The gaging station at 

Old Gaston, about 13 miles above Weldon, was established for comparative 

purposes. It has been found, upon brief study, that the Weldon gage record 

can not be utilized for discharge purposes without a disproportionate expenditure of funds if at all. The study therefore has been abandoned and the base 

data and information obtained are published herewith.

Location. At Seaboard Air Line Railway bridge, just north of Weldon, N. C., 

about 1 mile below mouth of Chockyott Creek and about 500 yards above the 

lower end of the "fall line."

Records available. Gage heights November 1, 1890, to December 31, 1912, in the 

publications of the United States Weather Bureau. The following corrections are 

necessary to the published records: December 13 to 31, 1907, and June 1 to 30, 

1908, subtract 4.0 feet, and January 1 to May 31, 1908, subtract 2.0 feet from 

the printed records. (See "Discharge measurements.") ^,

Drainage area. 8,420 square miles.

Gage. Property of the United States Weather Bureau, by which records are kept. 

The present gage is a chain gage attached to upstream guard timber in center 

panel of second 'through span from south end of bridge. The original gage is 

said to have been a staff gage in two sections, attached to a rock out in the channel 

and a tree on the right bank about 400 or 500 yards below the Seaboard Air Line 

Bridge. The zero of this gage is said to have been set at about low water, which 

was taken as the bottom of a hole in a large rock, familiarly known in the locality 

as "Cuba" rock. The first gage observer here was a Mr. Clark,and upon his 

death no record was kept for a time. A new gage, of the Missouri River wirecable type, was installed by the present observer, Mr. H. D. Alien, on April 1, 

1899. It was intended that this should read the same as the old gage, but the 

chain length and datum to which it was set are in question. This gage was just 

above the second rock pier from the south end of the bridge. In December, 

1907, the gage was destroyed and was replaced on December 13, 1907, by a chain 

It is questionable whether or not there was a change between 1899 and 1907.
EOAKOKE EIVER BASIN. 27

It was later discovered that this chain was 2 feet too long, and consequently 

on July 1, 1908, the new chain was shortened 2 feet. This chain was cut off 

on May 15, 1910, and a new chain, the present one, installed on May 25, 1910. 

During September or October, ^911, this gage was moved two bridge panels 

farther out into the river to its present location. On December 9, 1911, the 

chain length was found to be 67.60 feet (elongation probably due to stretch 

since installation) and was changed to the correct length, 66.30 feet. With the 

chain length correct the gage was found to read 0.60 foot low, by wye levels from 

the bench mark on the Bank of Weldon Building. (Elevation 64.20 feet above 

zero of gage.) See United States Weather Bureau publication "Daily river 

stages, principal rivers of the United States, Part X."

Channel. Sand, gravel, and small rocks. Probably shifting, especially at high 

stages.

Discharge measurements. Made from the foot walk on ^downstream side of Seaboard Air Line Railway bridge. Eleven discharge measurements were made at 

this station in 1911 and 1912 by the United States Geological Survey. (See 

table, p. 28.) Measurements Nos. 6 to 11 were made during the flood of March, 1912. 

If the Weldon measurements are plotted on cross section paper (gage heights 

in feet as ordinates, scale 4 feet to the inch, and discharge in second-feet as abscissas, scale 10,000 second-feet to the inch), it will be seen that a smooth curve can be 

drawn among the points representing measurements Nos. 1, 2, 3, 5, 6, and 7. 

This will be an approximate "free flow" or rising stage discharge curve for the 

March, 1912, flood at Weldon. Another smooth curve can be drawn among the 

.points representing measurements Nos. 1, 7, 8, 9, 10, and 11, and this will be a 

probable "backwater" or "falling stage" discharge curve for'the 'March, 1912, 

flood at Weldon. Measurement No. 4, made at the crest of the February, 1912, 

rise, will be found to be midway between the two curves. These curves may be 

used to determine the discharge at Weldon during the March, 1912, flood, using 

the curves over the proper periods of rising and falling stage as indicated by the 

measurements. The relation of gage height to discharge indicated by these 

curves, however, is probably not applicable to other periods and engineers making 

use of these data for discharge purposes should do so with caution. The discharge 

measurements at Old Gaston, made during the same periods (see p. 25), will be 

found to plot on a smooth curve, but the Survey has made no comparative study 

of these data.

Floods. The United States Weather Bureau publishes the maximum stage at Weldon 

as 60.3*leet, November 26, 1877, but from information obtained at Weldon in 

March, 1912, it seems probable that this value is about 7 feet too high namely, 

the 1877 flood readied a crest height of about 53 feet, referred to the present gage 

datum. The flood of March, 1912, reached a crest height of 50.3 feet (discharge 

about 162,000 second-feet) at 4.30 p. m. March 18, about 3 feet lower than the 

1877 flood. Plate IV, A, shows Roanoke River at Weldon during the flood of 

March, 1912 (gage height 47.9 feet, discharge about 120,000 second-feet), and 

Plate IV, B, a comparative view taken at medium low water. The horizontal 

lines and arrows on the piers show the crest height (gage height 50.3 feet) and the 

height at the time of the flood photograph.

Regulation. The Roanoke Rapids Power Co. has a series of low dams or wing walls 

that divert water from the river above Roanoke Rapids, about 8 miles above 

Weldon. It is probable that they cause little pondage. Officials of power companies at Roanoke Rapids and Weldon state that during seasons of low water they 

have noticed low periods about Tuesday evening or Wednesday morning each 

week, which they ascribe to the ponding of water from Saturday night to Monday morning by the power plants at Danville.
28 SUBFACE WATER SUPPLY, 1912, PAET II.

Diversions. The Roanoke Navigation & Water Power Co. diverts water from the 

river at Shaws Island, about 9 miles above Weldon. This company's canal is 

said to carry from 150 to 300 second-feet, with an average of about 250 second-feet. 

This water passes around the gaging section at Weldon, the outlet of the canal 

being about 200 yards below the bridge to which the gage is attached. Flow in 

. the canal is included in the discharge given in the table of discharge measurements.

Accuracy. The discharge measurements are accurate and reliable. The accuracy 

of the gage-height records for discharge purposes will best be determined by a 

detailed study of the data.

Cooperation. The work of the Survey at this station was done in cooperation with 

the Virginia-Carolina Power Co., William C. Whitner, president.

YADKIN OB PEEDEE BIVEB BASIN. 

YADKIN EIVEE, NEAR. SALISBURY, N. C.

Location. At the highway bridge known as the Piedmont Toll Bridge, 1,000 feet 

above the Southern Railway bridge, 6 miles east of Salisbury, and about 5 miles 

below the mouth of South Yadkin River.

Becords available. September 24,1895, to December 31, 1909; September 1, 1911, 

to December 31, 1912.

Drainage area. 3,400 square miles.

Gage. Standard chain gage attached to the highway bridge. From the date of 

establishment to May 31, 1899, the gage was at the Southern Railway bridge, 

and from the latter date it was at the highway bridge until moved jfeack to the 

railroad bridge early in the year 1903, where it remained until the end of the year 

1905. Since January 1, 1906, the gage has been at the highway bridge on the 

same datum as originally established there in 1899. The last gage at the railroad' 

bridge read the same as the gage at the highway bridge at gage height 3.2 feet 

but was not the same for higher and lower stages. There is some uncertainty as 

to the datum of the original gage at the railroad bridge.

Channel. Practically permanent; wide and rather rough.

Discharge measurements. Made from the highway bridge. During the time 

that the gage was at the railroad bridge most of the measurements were made 

from that bridge.

Winter flow. Ice or snow have little if any effect on the records of the station.

Artificial control. There are some developed powers on the river and tributaries 

above which may slightly affect the flow.

The following discharge measurement was made by W. E. Hall: 

October 28, 1912, gage height, 2.22 feet; discharge, 2,240 second-feet.

YADKIN RIVER NEAR PEEDEE, N. C.

Location. At a private ferry about 1,500 feet below the dam of the Rockingham 

 Power Co., half a mile below the mouth of Smith Creek and 1 mile above Partridge 

Creek.

Records available. August 9, 1906, to January 21, 1912.

Drainage area. Not measured.

Gage. Vertical timber gage on right bank above the ferry landing.

Channel. Wide, with rough bed, mostly rock, some of which projects from surface at 

low water. Current irregular. ' Discharge measurements. Made from the ferry boat.

Artificial control. The large power plant of the Rockingham Power Co., just above 

the station, was put into operation January 21, 1912, The tailrace of the plant 

empties into the river below the gage, so there is no flow past the gage at times 

when this plant is using all the flow of the river. There had not been much artificial regulation of the flow previous to January 21, 1912.

Accuracy. Owing to diurnal flictuations caused by the operations of the power plant 

above the station (see artificial control), two gage-height readings a day are not 

considered sufficient data upon which to base estimates of daily discfeirge subsequent to January 21,1912. No discharge measurements were made at this station 

during 1912.

Cooperation. All gage heights have been furnished by the engineers of the Rockingham Power Co.

NOTE. Daily discharge computed from a rating curve fairly well defined between 2,700 and 13,400 secondfeet. Below 2 500 and above 15,000 second-feet the rating is very uncertain and daily discharge has not 

been computed.

PEEDEE KIVEK AT CHEKAW, S. C.

Location. At the highway bridge in Cheraw, S. C., below the bridge of the Seaboard 

Air Line Kail way.

Records available. April 1,1891, to August 27,1908; November 2,1909, to December 31, 1912.

Drainage area. 6,670 square miles.

Gage. Vertical timber attached to bridge pier. The original gage and the bridge 

to which it was attached were washed away August 27,1908. The rating'for recent 

years would probably not apply to these old gage heights, and it is not certain that 

the new gage is set on the same datum as the former gage.

Discharge measurements. Made from the highway bridge to which the gage is 

attached. Some measurements have been made at the Seaboard Air Line Hallway 

bridge, one-half mile above.

Artificial control. Large Power plants at Buckingham, N. C., and at Whitney, N. C., 

put into operation early in 1912, seriously affect the flow at this station.

Accuracy. Estimates are based upon one gage-height reading a day and may be conconsiderably in error at low stages owing to diurnal fluctuations caused by the 

operation of power plants above. The 1912 estimate is based on the 1911 rating, 

which ie not developed for high stages. No discharge measurements were made 

at this station during 1912.

Cooperation. Gage heights are furnished by the United States Weather Bureau.

second-feet. The discharge was greater than 18,000 second-feet on days for which no estimates are given.
STTEFACE WATEE SUPPLY, 1912, PAET II. 33

SAVANNAH RIVER BASIN. 

TALLULAH EIVEE AT TALLULAH FALLS, GA.

Location. At the wagon bridge at Tallulah Falls, about one-fourth mile above the 

beginning of the falls proper, and 3J miles above the junction of Tallulah and Chattooga rivers. No important streams flow into Tallulah River below the station.

Records available. August 29 to October 19, 1900; January 18 to December 31, 

1901; July 15,1904, to September 30, 1912.

Drainage area. 191 square miles.

Gage. Standard chain gage attached to the bridge; datum same as that of the original 

vertical gage.

Channel. Rocky, rather deep; slow current at low stages, becoming very swift at 

high stages. Some change of rating has occurred, probably caused by bowlders 

lodging on or washing away from the shallow, rocky crest a short distance below.

Discharge measurements. Made from the upstream side of the wagon bridge.

Artificial control. The dam of the Georgia Railway & Power Co. at Tallulah Falls, 

about 1,000 feet below the station, was constructed during 1912. Backwater from 

this dam reached the gage about October 1,1912, necessitating the abandonment 

of the station.

Accuracy. For flood stages above gage height 6 feet the rating is not well developed.

Discharge measurements of Tallulah River at Tallulah Falls, Ga., in 1912.

TALLUIAH EIVEE AT MATHIS, GA.

Location. About one-fourth mile southeast of Mathis, Ga., railroad station on the

Tallulah Falls Railway and 500 feet below the mouth of Tiger Creek. The station

is about 5 miles above Tallulah Falls, Ga., and 1 mile below the Mathis storage

dam of the Georgia Railway & Power Co.

Records available. October 31 to December 31, 1912 (gage heights only). 

Drainage area. Not measured. 

Gage. Staff gage spiked to a big maple tree on the left bank. The present gage is

temporary and is to be replaced by a permanent gage at same place. 

Discharge measurements. Will be made by wading or from a cable. No discharge

measurements were made at this station during 1912. 

Artificial control. The storage dam of the Georgia Railway & Power Co., about 1

mile above the station, will, when completed, seriously interfere with the natural

conditions of flow at this place.

Daily gage height, in feet, of Tallulah River at Mathis, Ga.,for 1912.

BEOAD EIVEE (OF GEOEGIA) NEAE CAELTON, GA.

Location. At the Seaboard Air Line Railway bridge 3 miles east of Carlton, Ga., and

2 miles above the mouth of South Fork, Broad River. 

Records available. May 27, 1897, to December 31, 1912. 

Drainage 'area. 762 square miles.

Gage. Standard chain gage attached to the railroad bridge; datum unchanged. 

Channel. The bed of the stream is sand and gravel and may be slightly changeable.

The left bank overflows for about 400 feet at a gage height of 16 feet. 

Discharge measurements. Made from the upstream side of decked railroad bridge.

No discharge measurements were made at this station during 1912. 

Artificial control. The flow is affected little or not at all by artificial control. 

Accuracy. As no discharge measurements have been made at this station since 1910

it is not known what conditions may have affected the rating, and the estimates

for 1912 should be used with caution. 

Cooperation. Gage heights are furnished by the United States Weather Bureau.
36 SURFACE WATER SUPPLY, 1912, PART H.

ALTAMAHA RIVER BASIN. 

OCMULGKEE RIVER NEAR JACKSON, GA.

Location. At Pittmans Ferry, 8 miles southeast of Jackson, Ga., half a mile above 

the mouth of Yellow Water Creek and a short distance below Heards Creek. The 

station is 1J miles below the 100-foot dam and power plant of the Central Georgia 

Power Co.

Records available. May 18,1906, to December 31,1912.

Drainage area. 1,400 square miles.

Gage. Vertical staff in three sections, on right bank of river, upstream side of ferry 

landing; datum unchanged.

Channel. Bottom Bandy; shifts considerably, but the shifting has little, if any, 

effect on the rating, as the control is formed by a rocky ledge about 400 feet below

Discharge measurements. Made at the ferry, either from the ferryboat or a small

boat held in place by the ferry cable. 

Artificial control. Since the power plant of the Central Georgia Power Co. has been

in opja^Jon the artificial regulation has very greatly affected the normal low

water flow. 

Accuracy. The records are based on two gage-height readings a day, but as there is a

large diurnal fluctuation, due to the operation of the power plant above, it is

possible that the estimates of daily discharge may be considerably in error for

individual days, especially at low stages.

The following discharge measurement was made by W. E. Hall: 

December 11, 1912, gage height, 4.76 feet; discharge, 1,400 second-feet.
38 SURFACE WATER SUPPLY, 1912, PART II.

OCMULGKEE RIVER AT MACON, GA.

Location. At the Fifth Street bridge in the city of Macon, near Hie Southern Railway passenger depot and about 500 feet above the Central of Georgia Railway 

bridge.

Records available. October 18, 1895, to December 31, 1912.

Drainage area. 2,420 square miles.

Gage. The United States Weather Bureau gage originally used at this station is a 

heavy timber bolted to a pier of the Central of Georgia Railway bridge. A standard 

chain gage was installed October 9, 1905, on the downstream steel handrail of 

highway bridge, about 600 feet upstream from old gage. These gages have 

been referred to the same datum and have given practically the same readings. 

Since August 1,1912, the old relation of gage height to discharge has been considerably changed owing to the construction of a dock about 800 feet below 

the gage.

Channel. Both banks are high and neither is subject to overflow; bed soft and shifting; considerable change in the station rating curve has occurred as the result of 

changes in the river bed at and below the station.

Discharge measurements. Made from the downstream side of the highway bridge 

to which the gage is attached.

Artificial^omtrol. The natural condition of flow, especially at low stages, is likely 

to be considerably affected by the operations of the power dam near Jackson, Ga.

Accuracy. As the station is situated below the fall line, rapidly rising or falling stages 

are likely to be attended by variations in surface slope, causing greater or less 

discharge than for the normal rating. The possible error in mean gage heights 

due to artificial control may cause the estimates for individual days to be considerably in error, especially at low stages. No rating has been developed for the 

changed conditions due to the construction of the new dock about 800 feet below 

the gage, and, owing to the uncertainty as to the applicability of the old rating to 

observations made during the period of the construction of the dock, no estimates 

of daily discharge are given for 1912.

Cooperation. Since June 1,1899, all gage heights have been furnished by the United 

States Weather Bureau.

OCONEE RIVER NEAR GREENSBORO, GA. j^

Location. At the highway bridge, 5 miles west of Greensboro on the road to Madison, Ga., about 4 miles above the mouth of Apalachee River and JJ miles below 

Town Creek.

Records available. July 25, 1903, to December 31, 1912.

Drainage area. 1,100 square miles.

Gage. Standard chain gage attached to the bridge; datum unchanged.

Channel. Bed composed chiefly of sand; slightly shifting.

Discharge measurements. Made from the downstream side of the bridge.

Artificial control. In the spring of 1911 a new dam was completed near Athens, 

Ga., greatly increasing the storage capacity in that vicinity. The operation of 

this dam does not appear to cause very great daily fluctuation at Greensboro, but 

it does cause abnormally low daily discharge at times.

Accuracy. Owing to the operation of power plants above the station it is probable 

that the estimates of daily discharge may be somewhat in error for individual 

days, especially at low stages.

OCONEE RIVER AT DUBLIN, GA.

Location. At the Wrightsville & Tennille Railroad bridge at Dublin, Ga. 

Records available. February 11, 1898. to December 31, 1912; fragmentary records

prior to 1898.

Drainage area. 4,180 square mileB. 

Gage. Vertical timber attached to the downstream side of the central or turn-span

pier of the railroad bridge; also a short sloping section bolted to rock just above

the bridge on the right bank. The datum has not been changed. 

Channel. Rocky and nearly permanent at the wagon bridge, but shifting of the

bottom in the channel below causes slight changes in the discharge rating. At a

stage of about 20 feet the left bank overflows for 1,100 feet through an iron frame

trestle approach to the bridge. This ground is thickly covered with brushy

growth, which probably retards the flow of water over the overflow section. The

right bank does not overflow. 

Discharge measurements. Made from the downstream side of the wagon bridge,

500 feet above the railroad bridge. 

Artificial control. The only power plant of consequence is near Athens, Ga., and

is so far above the station that its operation probably does not affect the accuracy

of observations at Dublin. 

Accuracy. Lack of data covering changes in channel makes results at th|fcstation

uncertain prior to 1910. A good degree of accuracy may be obtained by making

frequent discharge measurements. 

Cooperation. Since 1898 the gage heights have been furnished by the United States

Weather Bureau.

The following discharge measurement was made by W. E. Hall: 

April 24, 1912, gage height, 19.98 feet; discharge, 32,300 second-feet.

EASTERN GULF OF MEXICO DRAINAGE BASINS.

APALACHICOLA RIVER BASIN. 

CHATTAHOOCHEE RIVER NEAR NORCROSS, GA.

Location. At Medlock's bridge, 4J miles north of Norcross, Ga., 1J miles above the 

mouth of John Creek, and about 5 miles above Suwanee Creek.

Records available. January 9, 1903, to December 31, 1912.

Drainage area. 1,170 square miles.

Gage. Standard chain gage on the toll bridge. The original gage was a vertical staff 

attached to an oak tree on the right bank, about 100 feet above the bridge. A chain 

gage, established March 14, 1903, was read in connection with the vertical gage 

until June 28, 1905, when the present gage was installed. The datum of the vertical staff gage originally used and that of the present chain gage has not been 

changed.

Channel. The right bank is high and overflows only slightly; the left bank will overflow for about 800 feet at a gage height of 16 to 18 feet. The bed of the stream is 

sandy and changeable, necessitating frequent discharge measurements and occasional changes in the rating.

Discharge measurements. Made from the downstream side of the bridge.

Artificial control. Dams near Gainesville, Ga., and on Chestatee Rive^Bfterfere 

with the natural flow. It is thought that the two readings a day give a good daily 

mean gage height.

Accuracy. Except for possible error in mean gage heights due to artificial control, 

the results at this station are considered excellent.

Cooperation. Since May 1,1910, the gage heights have been furnished by the United 

States Weather Bureau.

The following discharge measurement was made by W. E. Hall: 

June 14, 1912, gage height, 8.27 feet; discharge, 7,580 second-feet. 

Several measurements made early in 1913 were used in determining the discharge 

rating for 1912.

CHATTAHOOCHEE RIVER AT WEST POINT, GA.

Location. At the Montgomery Street Bridge, West Point, Ga., until October 21, 

1912; after that date at a point about a mile upstream, just below the mouth of 

Oseligee Creek, about 300 feet east of the West Point waterworks pumping plant, 

and about 4 miles above Long Cane Creek.

Records available. July 30, 1896, to December 31, 1912.

Drainage area. 3,300 square miles.

Gage. The new staff gage is at a'different datum from the chain gage formerly used 

and is in two sections; the lower section, reading from 0 to 6 feet, is near the right 

bank; the upper section, reading from 6 to 25 feet, is fastened to a tree on the 

left bank.

Channel. Rough, rocky bottom and fairly permanent section; banks are overflowed 

at high stages.

Discharge measurements. May be made from a boat at a section near the new 

gage, or from the highway bridge where the gage was formerly located; no tributaries enter between the two sections.

Artificial control. The operation of power plants at points above causes some 

diurnal fluctuation. The Langdale Dam, 5 miles below the station, forms a pond 

reaching back as far as West Point. This affected the gage heights at t|b> highway bridge, making the old rating valueless for 1912. The new gage established 

in October, 1912, is not affected by backwater.

Accuracy. A new rating was developed for the old gage at the highway bridge

applying to the changed conditions during 1912. A rating has also been developed

for the new staff gage covering low and medium stages. Discharges computed

' from the two ratings for the period October 21 to December 31, 1912, agree within

0.2 per cent.

Cooperation. Gage heights after October 21, 1912, have been furnished by the 

Columbus Power Co., of Columbus, Ga. The hydraulic engineer for that company has also assisted in making discharge measurements.

APALACHICOLA RIVEK BASIN. 51

CHATTAHOOCHEE EIVEE AT COLUMBUS, GA.

Location. Behind the Columbus Gas Works between Columbus, Ga., and Girard, 

Ala., just below mouth of Hollands Creek and about half a mile below Eagle and 

Phoenix dam.

Records available. September 3 to December 31, 1912.

Gate. Vertical staff on left bank 600 feet above new concrete highway bridge and 

about 800 feet above steamboat landing. Zero of gage, 185 feet above sea level.

Channel. Deep near left bank and gradually shallowing near the right bank; bed 

smooth and sandy and will probably shift at every flood; left bank high; overflows about 75 feet back to a secondary bank, which is not overflowed. At low 

stages the right bank is a large sand bar about 300 feet wide; the sand is deposited 

by Hollands Creek and the bar is changed at every flood. Current swift at all 

stages.

Discharge measurements. Made from boat. A light steel cable is stretched from 

the left bank to the sand bar; cable is fastened to trees on the left bank and rests 

on an A-frame on the sand bar; a tag line is stretched just below the cable.

Winter flow. Not affected by ice.

Artificial control. The operation of dams above the station causes constant fluctuation in gage heights.

Accuracy. Conditions very poor and many measurements must be made to insure 

accurate results.

Cooperation. The gage heights and discharge measurements have all been furnished by the Columbus Power Co.

FLINT RIVER NEAR WOODBTJRY, GA.

Location. At the Macon & Birmingham Railroad bridge, 3 miles east of Woodbury,

Ga., about one-third of a mile above the mouth of Cane Creek and one-fourth of

a mile below Elkins Creek.

Records available. March 29, 1900, to December 31, 1912. 

Drainage area. 1,090 square miles. 

Gage. Vertical staff, in two sections, on the left bank about 300 feet above the

railroad bridge. The datum of the gage, which is 660 feet above eea level, has

remained the same since the establishment of the station.
APALACHICOLA RIVER BASIN". 53

Channel. The bottom is rough, consisting chiefly of rock, and currents are irregular. Above gage height 10 feet the banks are subject to overflow for a width of 

about 360 feet, but all water passes beneath the bridge and its approaches.

Discharge : neasurements. Made from the downstream side of the railroad bridge, 

which does not make a right angle with the current.

Artificial c< mtrol. Power developments on tributary streams above affect the daily 

flow at low stages.

Accuracy. -Since July 1, 1910, the records are based on one gage height reading a 

day, and as the operation of the power plants above causes some diurnal fluctuation the estimates of daily discharge may be considerably in error for individual 

days, especially at low stages. The discharge rating was fairly constant for a 

number of years, but changed considerably in 1909 and 1910, probably due to 

conditions at the shoals one-half mile below. The highway bridge built a short 

distance below the gage in September, 1911, materially affected the conditions 

of flow and necessitated a new discharge rating.

Cooperation. Since July 1, 1910, the gage heights have been furnished by the 

United States Weather Bureau.

The following discharge measurement was made by W. E. Hall: 

August 24, 1912, gage height, 0.93 foot; discharge, 650 second-feet. 

An additional measurement made early in 1913 was used in determining the discharge rating for 1912.

Daily gage height, in feet, of Flint River near Woodbury, Ga.,for 1912.

APALACHICOLA RIVER BASIN. 55

FLINT RIVER NEAR CULLODEN, GA.

Location. At Grays Ferry, 14 miles southwest of Culloden, Ga., 1J miles above the

mouth of Auchumpkee Creek, and about 3 miles above the old gage near Musella,

Ga., which was read for a short time in 1907. 

Records available. July 1 to December 31, 1912. 

Drainage area. 2,000 square miles. 

Gage. Vertical timber attached to a willow stump on the left bank just below the

ferry landing; datum unchanged. 

Channel. Sandy and likely to shift at the station, but a rock ledge one-half mile below

will probably give a permanent control. 

Discharge measurements. Made from the ferryboat.

o Average daily discharge. Mar. 15-19, estimated at 16,000 second-feet. (Determined from observer's 

notes and by comparison with other Flint River stations.)

* Average daily discharge, Apr. 21-24, estimated at 14.000 second-feet. (Determined from observer's 

notes and by comparison with other Flint River stations.)

NOTE. Daily discharge computed from a rating curve fairly well defined below 2,700 second-feet. Above 

6,000 second-feet the estimates are only approximate.

ALTAMAHA RIVER BASIN. 57

FLINT RIVER NEAR MONTEZUMA, GA.

Location. At the iron highway bridge about 1 mile west of Montezuma This is the 

second or upper wagon bridge. It is above the mouth of Bucks Creel.

Records available. October 1, 1904, to December 31, 1912.

Drainage area. 2,700 square miles.

Gage. Chain gage attached to the upstream side of the bridge; datum unchanged.

Channel. The right bank will overflow for a great distance at a stage of about 12 feet. 

The overflowed portion is largely covered with a dense growth of brush. The left 

bank is not liable to overflow. The current toward the left bank becomes sluggish at low stages, and at times there is considerable back current near the bank. 

The bottom is somewhat shifting.

Discharge measurements. Made from the downstream side of the highway bridge.

Artificial control. The flow is not appreciably affected by artificial control.

Accuracy. A fairly good rating has been developed, but the gage heights are very 

uncertain and the data should be used with caution.

Cooperation. Gage heights are furnished by the United States Weather Bureau.

The following discharge measurement was made by W. E. Hall: 

April 27,1912, gage height, 13.84 feet; discharge, 10,500 second-feet.

Daily gage height, in feet, of Flint River near Montezuma, Ga.,for 1912.

APALACHICOLA BIVEB BASIN. 59

FLINT BIVER AT ALBANY, GA.

Location. At the Dougherty County highway bridge in the city of Albany, 700 

feet below the Atlantic Coast Line Railroad bridge.

Records available. April 10,1893, to December 31,1912. (United States Weather 

Bureau gage heights.) Discharge measurements were begun by the Geological 

Survey in 1901, and estimates of daily discharge have been made from January 1, 

1902, to December 31, 1912.

Drainage area. 5,000 square miles.

Gage. Standard chain gage installed at the bridge by the United States Geological 

Survey April 20, 1904. The original staff gage was washed out in 1898. It was 

again injured in 1902, and on June 18, 1902, a new gage was installed by the 

United States Weather Bureau at a datum 0.75 foot lower than that of the former 

gage. The 1902 gage heights, as published by the United States Weather Bureau 

and the United States Geological Survey, all refer to the new gage datum. The 

present standard chain gage has the same datum as and reads in conformity with 

the United States Weather Bureau gage.

Channel. The channel at and below the gage may shift slightly but the control is 

such that conditions of flow are practically permanent. The river overflows both 

banks but only under the approaches to the bridge.

Discharge measurements. Fairly accurate measurements can be made at the 

section at the Atlantic Coast Line bridge, although it is very rough, and train 

switching in the railroad yard interferes with the work. The section at the 

Georgia Northern Railway bridge, 1 mile above, at which measurements are 

sometimes made, is considered better, especially for medium and low stages.

Artificial control. Power developments on Muckalee Creek, which joins Flint 

River about 2 miles above the station, cause considerable diurnal fluctuation, 

especially at low stages. It is probable that the flow is also affected by other 

power plants farther up the river.

Accuracy. As the records are based on one gage reading a day, made at 7 a. m., it is 

probable that the estimates of daily discharge are somewhat in error, especially at 

low stages. The actual daily discharge is probably greater than that indicated 

by the 7 a. m. reading.

Cooperation. Gage heights are furnished by the United States Weather Bureau.

FLINT EIVEE AT BAINBEIDGE, GA.

Location. At the county wagon bridge half a mile from Bainbridge and about 25 

miles above the confluence of Flint and Chattahoochee rivers.

Records available. October 7,1904, to Decembers, 1912. (Weather Bureau gageheight readings.) Discharge measurements were begun by the Geological Survey June 11, 1908, and estimates of daily discharge have been made from January 1, 1908, to December 31, 1912.

Drainage area. 7,410 squafe miles. (United States Weather Bureau.)

Gage. Standard chain gage attached to the highway bridge. The datum haa not 

been changed since June 11, 1908, at which time it was adjusted to its original 

datum. During part of the time prior to this date the chain was wrongly adjusted. 

Gage heights for 1908 were all corrected before publication in Water-Supply 

Paper 242.

Channel. Bed is soit and likely to shift, but appears to have remained fairly permanent, as indicated by constancy of discharge ratings.

Accuracy. It is possible that daily discharge as determined by one gage-height reading^, day may be somewhat in error for individual days, otherwise the accuracy 

i^^od for low and medium stages.

Cooperation. Gage heights are furnished by the United States Weather Bureau.

The following discharge measurement was made by W. E. Hall: 

November 13, 1912, gage height, 11.57 feet; discharge, 14,000 second-feet.

/

CHOCTAWHATCHEE RIVER BASIN.

CHOCTAWHATCHEE RIVER NEAR NEWTON, ALA.

At the wagon bridge 1 mile west of Newton, Ala., and 1 mile below the

railroad crossing at Elba Junction, Ala., about 5 miles below the mouth of West

Choctawhatchee River. 

Records available. June 11 to October 13, 1906; April 22, 1907, to August 22, 1908;

October 20, 1911,to August 3, 1912. 

Drainage area. Not determined. 

Gage. Standard chain gage attached to the downstream side of the wagon bridge;

datum unchanged. The gage heights during 1906 were taken from a vertical gage

near Elba Junction, but they were reduced to agree with the chain gage. 

Channel. Both banks are high and not likely to overflow. Conditions of flow may

possibly be affected by dredging of channel. 

Discharge measurements. Made from the wagon bridge. 

Artificial control. Probably some effect from small power plant above. 

Accuracy. No rating was developed for the changed conditions of section in 1911-12.

No discharge measurements were made at this station during 1912.

PEA RIVER AT PERA, ALA.

Location. At the Elton wagon bridge half a mile west of Pera, Ala., about 10 miles 

above the mouth of Flat Creek; no tributary streams except very small ones come 

in nearer the station.

Records available. August 27, 1904, to December 31, 1912.

Drainage area. 1,180 square miles.

Gage. Standard chain gage attached to the bridge; datum unchanged.

Channel. In soft rock; nearly permanent. |fc.

Discharge measurements. Made from the downstream side of the wagon bridge 

to which the gage is attached.

Artificial control. Power plants on Whitewater Creek, a tributary stream above the 

station, cause diurnal fluctuations in the low-water flow. The gage is read twice a 

day to lessen the effect of such fluctuations.

Accuracy. The estimates of daily discharge may be considerably in error for individual days due to the operation of the power plants above the station. No discharge measurements were made at this station during 1912.

Creek, 8 miles west of Andalusia, Ala., a statiqn on the Central of Georgia and 

Louisville & Nashville railroads.

Records available. August 24, 1904, to December 31, 1912.

Drainage area. 1,290 square miles. &'

datum unchanged.

Channel. In soft bed rock and practically permanent.. Both banks are subject to 

overflow at high stages.

Discharge measurements. Made from the wagon bridge. No discharge measurements were made at this station during 1912.

Artificial control. The flow is probably not affected by artificial control, but at 

times may be affected by logging operations.

Accuracy. Conditions of flow at this station are practically permanent and a good 

rating has been developed in previous years. Estimates for 1912 are based on 

1911 rating.

MOBILE RIVER BASIN. 

OOSTANATJLA RIVER AT RESACA, GA.

Location. At the Western & Atlantic Railroad bridge in Resaca, Ga., 3 miles below 

the junction of Conasauga and Coosawattee rivers and 1 mile above the mouth of 

Camp Creek.

Records available. 1891 to 1898 (gage heights by the United States Weather Bureau 

and discharge measurements and gage heights by the United States Geological 

Survey); 1899 to 1904 partial records of gage heights; continuous records January 

1, 1905, to December 31, 1912.

Drainage area. 1,610 square miles.

Gage. Heavy vertical timber attached to the downstream side of the bridge pier in 

the middle of the river; datum unchanged.

Channel. Slightly shifting at and below the station. The left bank is low and 

overflows during high water for 480 feet.

Discharge measurements. Usually made from the downstream side of the railroad bridge but at times from a boat at the ferry, about 200 feet above, where the 

section is somewhat better. No discharge measurements were made at thiastation during 1912. W*

Artificial control. Except on the smaller tributaries there are very few milldams, 

and.these have little or no effect on the flow at the station. The channel is sometimes obstructed by logs under the left span of the bridge.

Accuracy. A good rating has been developed in previous years for low and medium

Cooperation. Gage heights are furnished by the United States Weather Bureau.

COOSA RIVER AT RIVERSIDE, ALA.

Location. At the Southern Railway bridge at Riverside, Ala., 1 mile above the 

mouth of Blue Eye Creek and about 7 miles above Choccolocco Creek.

Records available. September 25, 1896, to December 31, 1912.

Drainage area. 7,060 square miles.

Gage. Standard chain gage attached to the right-bank end of the downstream side 

of the railroad bridge. The original wire gage was located on the downstream side 

of the bridge near the middle of the river. The gage datum has not been changed 

since the station was established.

Channel. For a part of the width the current is broken by a ledge above. Both banks 

are! high and do not overflow, and the bed of the stream is rocky and permanent.

Discharge measurements. Made from the downstream side of the railroad 

bridge. No discharge measurements were made at this station during 1912.

Artificial control. The flow is not noticeably affected by artificial control at the 

comparatively few dams above. Four navigation locks have been constructed, 

the nearest of which is Lock 4, about 4 miles above the station.
MOBILE RIVER BASltf. 71

ALABAMA RIVER AT SELMA, ALA.

Location. At the highway bridge in Selma, Ala.

Records available. January 1, 1899, to December 31, 1912. The station was 

originally established by the United States Army Engineer Corps but in 1890 

gage height records were begun by the United States Weather Bureau. Although 

it ia not thought that the discharge rating can be accurately applied farther back 

than 1899, flow estimates based on earlier gage heights will probably be of some 

value.

Drainage area. 15,400 square miles.

Gage. Standard chain gage was installed by the United States Geological Survey 

March 22, 1906, on the downstream side of the highway bridge. The United 

States Weather Bureau gage formerly used was in two sections the low-water 

portion, reading from 3 to +5.1 feet, being fastened to the lower side of the 

cofferdam on the second pier, and the upper portion, reading from 5.1 to 55 feet, 

being fastened to the draw pier. All gages have had the same datum, but the 

bad condition of a short low-water section caused some error in the low-water 

readings prior to 1906, especially those of the year 1904.

Channel. In soft limestone, deep, with swift current, and difficult to sound <Jfen 

at ordinary stages. Both banks are high, but the left is subject to overflow at 

extreme high water.

Discharge measurements. Made from the highway bridge to which the gage is 

attached. No discharge measurements were made at this station during 1912.

Accuracy. Conditions of flow are somewhat changeable, but a fairly good rating 

has been developed for recent years.

Cooperation. Gage heights are furnished by the United States Weather Bureau.
MOBILE BIVER BASIN. 73

ETOWAH RIVER NEAR BALL GROUND, GA.

Location. At the iron wagon bridge about 3 miles southeast of Ball Ground, Ga., and 

one-fourth mile below the mouth of Longswamp Creek.

Becords available. May 16, 1907, to December 31, 1912.

Drainage area. 466 square miles.

Gage. A standard chain gage, attached to the upstream side of the bridge, was installed August 18, 1908, replacing the vertical staff gage, located 75 feet below 

the bridge. The chain gage was set to read with the vertical staff at low stages 

and will differ only very slightly at other stages.

Channel. The left bank does not overflow, but the right bank overflows about 500 

feet beyond the end of the bridge approach at high stages. The current is somewhat broken arfd is disturbed by a rough, rocky bed and curved channel above.

Discharge measurements. Made from the uptsream side of the wagon bridge. 

No discharge measurements were made at this station during 1912.

Artificial control. The operation of a number of mills above may cause slight variations in flow. On this account the gage is read twice a day.

Accuracy. The rating is somewhat affected by shifting of the stream bed some distance below the station. '"} *

ETOWAH RIVER NEAR ROME, GA.

Location. At Freemans Ferry, 5 miles above Rome, Ga., where Etowah and Oostanaula rivers unite to form Coosa River; 1 mile below mouth of Dikes Creek. 

Records available. August 17, 1904, to December 31, 1912. 

Drainage area. 1,800 square miles. 

Gage. Vertical gage in three sections, on left bank 250 feet below the ferry; datum

unchanged.

Charm el. Both banks are subject to overflow during high water. 

Discharge measurements. Made from the ferryboat or from a small boat held

in place by the ferry cable. No measurements can be made at high stages. No

discharge measurements were made at this station during 1912. 

Artificial control. The operation of the iew milldams above will seldom affect

the flow, but to provide for possible daily fluctuations the gage is read twice a

day. 

Accuracy. Conditions of flow are probably permanent, and an excellent rating has

been developed in previous years for low and medium stages.

Daily gage Jieight, in feet, of Etowah River near Rome, Ga.,for 1912. "jfc^

TALLAPOOSA EIVEE AT STUEDEVANT, ALA.

Location. At the Central of Georgia Railway bridge, one-fourth mile west of Sturdevant, Ala., and 5 miles below the mouth of Hillabee Creek.

Records available. July 19, 1900, to December 31, 1912.

Drainage area. 2,460 square miles.

Gage. A vertical staff gage on the right bank of the river about 2,000 feet above 

the bridge. The original gage was a staff in two sections attached to the pier of 

the railroad bridge. A standard chain gage, installed July 10, 1905, was read 

until the summer of 1906, when the present gage was installed. The readings of 

the new staff gage are all corrected to agree with the readings of the standard 

chain gage, referred to its original datum at the railroad bridge.

Channel. Rocky and permanent; one side deep and sluggish at low stages. Both 

banks overflow for about 200 feet at extreme high stages.

Discharge measurements. Made from a plank walk resting on the lower members 

of the decked railroad bridge. Some low-water measurements made from boat. 

No discharge measurements were made at this station during 1912.

Artificial control. The flow is under no artificial control except at a number of 

small mills a great distance upstream. .

Accuracy. A good rating has been developed in previous years and excellent resims 

are obtained from this station. Estimates for 1912 are based on 1911 rating.

Daily gage height, in feet, of Tallapoosa River at Sturdevant, Ala., for 1912. 

[C. J. Stowe, observer.]

TOMBIGBEE. RIVER AT COLUMBUS, MISS.

Location. At the county highway bridge at Columbus, Miss., 2 miles above the 

mouth of Luxapallila Creek and about 6 miles below the mouth of Tibbee Eiver.

Records available. July 13, 1905, to December 31, 1912. Also for 1900 to 1904, 

using the gage heights furnished by the United States Weather Bureau, some of 

which, especially for low stages, were very greatly in error.

Drainage area. 4,440 square miles.

Gage. Chain gage was installed by the United States Geological Survey on July 13, 

1905, at the highway bridge 1,000 feet above the original site of the gage of the 

United States Weather Bureau. The new gage was set to read the same as the first 

United States Weather Bureau gage at low water, which makes it practically on 

the same datum, as the low-water surface is almost level.

Channel. The right bank is high and seldom overflows. The left bank overflows 

only under the bridge approach at a gage height of about 20 feet. The bed of the 

stream is of soft limestone or chalk and conditions of flow are somewhat changeable

Discharge measurements. Made from the wagon bridge.

Accuracy. Estimates may be somewhat in error at low stages, due to changes at cocgto* 

trolling section.

The following discharge measurement was made by W. E. Hall: 

April 8, 1912, gage height, 17.78 feet; discharge, 24,500 second-feet.

Daily gage height, in feet, of Tombigbee River at Columbus, Miss., for 1912. 

[C. R. Snackelford, observer.]

TOMBIGBEE RIVER- AT EPES, ALA.

Location. At the Alabama Great Southern Railroad bridge just below the mouth of 

Jones Creek, about half a mile from Epes, Ala.

Records available. 1900 and 1901 (discharge measurements were made by the 

United States Geological Survey and a rating was developed for these years); 

November 29,1904, to December 31,1912. A record of approximate gage heights, 

based on a gage painted on one of the bridge piers, has been kept by the Alabama 

Great Southern Railroad for a number of years.

Drainage area. 8,830 square miles.

Gage. Standard chain gage attached to the railroad bridge; datum unchanged.

Channel. At flood stages gage heights of 38 feet and over the left bank overflows 

for about seven-eighths of a mile under the trestle approach to the bridge. Some 

changes in section have probably occurred since the station was established.

Discharge measurements. Made from the downstream side of the railroad bridge. 

No discharge measurements were made at this station during 1912.

Accuracy. Good results have been obtained at this station in the years when sufficient discharge measurements were made to fix the rating curve.

BLACK WARRIOR RIVER NEAR CORDOVA, ALA.

Location. At the Kansas City, Memphis & Birmingham Railroad bridge 1 mile east 

of Cordova and just below the mouth of Cane Creek; 12 miles below junction of 

Mulberry and Sipsey forks and 6 miles below the mouth of Blackwater Creek.

Records available. May 21, 1900, to December 31, 1912.

Drainage area. 1,900 square miles.

Gage. Staff gage in three sections, the lower one being a sloping timber bolted to 

bed rock, graduated from 0.6 to 10.0 feet; the other two sections are vertical 

timbers. All the sections are on the right bank near the railroad bridge. The 

datum of the gage has not been changed, but several gages at slightly different 

sites have been used.

Channel. The bed is rocky with a fair current except at low stages; at high stages 

the left bank overflows under the bridge.

Discharge measurements. Made from the railroad bridge. Some of the low-water 

measurements have been made by wading or from a boat at other sections nearby. 

No discharge measurements were made at this station during 1912.

Accuracy. The minimum flow is especially low per square mile of drainage area, 

and the rating at this stage is subject to considerable change.

Cooperation. Gage heights furnished by the United States Engineer Corps.

SUMMARY OF DISCHARGE PER SQUARE MILE.

The following summary of discharge per square mile is given to 

allow ready comparison of relative rates of run-off from different 

areas in the south Atlantic coast and eastern Gulf of Mexico drainage 

basins. It shows in a general way the seasonal distribution of run-off 

and the effect of snow, ground, surface, and artificial storage. But 

the most important fact worth noting is the almost entire lack of. 

uniformity or agreement between any two stations. It indicates 

that the discharge of each stream is a law unto itself and that all 

projects dependent upon stream flow, if they are to be developed 

along the safest and most economical lines, must be based on records 

of stream flow collected with great care over a long series of years as 

near the location of the project under consideration as possible.
