AUTHORIZATION AND SCOPE OF WORK.

This volume is one of a series of 12 reports presenting results of 

measurements of flow made on streams in the United States during 

 1913.

Six of the reports for 1913 contain data for the year ending September 30, and the other six for the calendar year, as indicated in 

the table on page 6.

The data presented in these reports were collected by the United 

States Geological Survey under authority implied in the organic law 

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

Provided, That this officer [the Director] shall have the direction of the geological 

survey and the classification of public lands and examination of the geological structure, 

mineral resources,, and products of the national domain.

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

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

1895, successive 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 years ending June 80, 1895-1914.

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

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

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

1911 to 1914,inclusive....................................... 150,000

In the execution of the work many private and State organizations 

have cooperated, either by furnishing data or by assisting financially 

in collecting the 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 15.

6 SURFACE WATER SUPPLY, 1913, PART II.

Measurements of stream flow have been made at about 3,000 points 

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

Peninsula and the Yukon-Tanana region, and in the Hawaiian Islands. 

On July 1, 1913, 1,388 gaging stations were being maintained by the 

Survey and the cooperating organizations and during the year many 

miscellaneous discharge measurements were made at other points. 

In connection with this work data were also collected in regard to 

precipitation, evaporation, storage reservoirs, river profiles, and water 

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

the regular water-supply papers from time to time.

PUBLICATIONS.

A report for each year has been prepared embodying the streamflow 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 1901 gage heights and discharge measurements were published in water-supply papers or bulletins and estimates of monthly 

discharge in annual reports; since 1901 both classes of data have 

been published in water-supply papers, and they are now being 

published in 12 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, acre-feet, and millions of 

cubic-feet. The units used in this series of reports are second-foot, 

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

of cubic-feet. They may be defined as follows:

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

is a unit of rate of discharge of water flowing in a stream. A second 

foot is the rate of discharge of water flowing in a channel of rectangular cross-section, 1 foot wide and 1 foot deep, at an average velocity of 1 foot per second. It is generally used as a fundamental
10 SURFACE WATER SUPPLY, 1913, PART II.

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

in the tables of convenient equivalents (p. 11).

"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 work.

"Millions of cubic-feet" is a unit used to express quantities of 

water stored in reservoirs and is most frequently used in studies of 

flood control.

The following terms used in these reports are not in very common 

use and may be defined as follows: 

"Discharge relation" is an abbreviation for the term "relation of 

gage height to discharge."

"Control," "control section," and "point of control" are terms 

used to designate that section or sections of the stream below the 

gage which determines the discharge relation at the gage. It should 

be noted that the control section may not-be the same at all stages.

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

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

would fall if there were no flow.

EXPLANATION OF DATA.

For each regular gaging station the following data (so far as available) are given: Description of the station, list of discharge measurements, table of daily gage height, table of daily discharge, table of 

monthly and yearly discharge and run-off. For stations at weirs or 

dams the gage-height table is usually omitted.

In .addition to statements regarding the location and equipment of 

stations, the descriptions give information in regard to any condition 

which may affect the constancy of the relation of gage height to discharge (the discharge relation, p. 10), covering such points as ice, 

logging, shifting channels, and backwater; also information regarding diversions which decrease the total flow at the gage. Statements 

are also made regarding the accuracy of the data.

The table of daily gage height shows 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, though 

at many stations only one reading is made each day. At a comparatively few stations automatic gages are used, some of which give a 

continuous record of river stage in the form of a hydrograph, and 

others a record printed' at regular intervals from which the mean 

daily gage height can be computed. The gage height given in the 

table represents the elevation of the surface of the water above the 

zero of the gage. When the discharge relation is affected by ice or 

by backwater from obstructions, all gage heights 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 locatecl somewhat below the lowest known flow, so that negative readings shall 

not occur.

In the tables of daily gage height the use of zeros in the hundredths 

place indicates the limits of accuracy to which the gage was read and 

to which the mean daily gage height was computed. If a gage is 

read to tenths or half-tenths once a day or to tenths twice a day no 

zeros appear in the hundredths place for any stage. If the gage is 

read .to half-tenths twice a day or to quarter-tenths or hundredths,

EXPLANATION OF DATA. 13

regardless of the number of readings a day, the gage heights are published to hundredths, and zeros appear in the hundredths place, below 

a certain limiting stage. This limiting stage is so selected that the 

average error in the mean daily discharge, resulting from not using 

tHe mean daily gage height to hundredths above that stage, shall 

not be greater than 2 per cent. For automatic gages the allowable 

average error of the daily discharge has been taken as 1 per cent. 

The selection of the percentage is arbitrary, but it should be noted 

that the maximum error will in all cases be twice the average error. 

In like manner half-tenths are used from the hundredths limit to 

another higher limit, above which only tenths are used. It is the 

aim to have the gage height observations at each gaging station 

recorded to the degree of refinement required by the above method 

of use, but in practice it is found necessary, in order to avoid confusion in the gage observer's record, to have the observations for all 

stages recorded to the degree of refinement required for low stages, 

which usually necessitates readings to hundredths of a foot.

The discharge measurements and gage heights are the base data 

from which rating tables, daily discharge tables, and monthly discharge tables are computed. The base data for the tables presented, 

in this report, unless otherwise stated in description of station, have 

been collected by the methods commonly used at current-meter gaging stations and described in standard textbooks.

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 height and daily discharge.

The table of daily discharge prepared from the rating table and 

gage-height table gives the discharge in second-feet corresponding to 

the mean of the gage readings observed each day.

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 of "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.

Plates I and II show typical gaging stations and current meters 

and gages used in the work.
14 SURFACE WATEE SUPPLY, 1913, PAST II. 

ACCURACY OF FIELD DATA AND COMPUTED BESUI/TS.

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

of channel and of the relation, between discharge and stage and (2) 

on the accuracy of observation of stage, measurements of discharge, 

and interpretation of 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 

curves used, and an accuracy column is inserted in the monthly discharge table. For the rating curves "well-defined" indicates, in 

general, that the rating is probably accurate within 5 per cent; 

"fairly well defined," within 10 per cent; "poorly defined" 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 

curve, the probable reliability of the observer, the number of gage 

readings per day, the range of the fluctuation in stage, 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 figures showing discharge per square mile and depth of 

run-off 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. For this reason the computations of "second-feet per square 

mile" and "run-off, depth in inches" have not been made for stations draining areas having an annual rainfall of less than 20 inches, 

nor for those stations draining areas of over 20 inches of rainfall for 

which it is believed that the computations would be uncertain and 

misleading because of the presence of large noncontributing districts 

in the measured drainage area, of omitting estimates of water 

diverted for irrigation or other use, or of artificial control or unusual 

natural control of the flow of the river above the gaging station. All 

values of "second-feet per square mile" and "run-off, depth in 

inches" previously published by the Survey should be used with 

extreme caution, and such values in this report should be used with 

care because of possible inherent sources of error not known to the 

Survey.
JAMES RIVER BASIN. 15

In general the base data collected eacli year by the Survey engineers 

are published, not only to comply with the law but also to afford any 

engineer the means of analyzing in detail 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 tables of daily discharge 

allow more detailed studies of the variation in flow. 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.

Records available. August 18, 1895, to December 31, 1913.

Drainage area. 2,060 square miles.

Gage. Chain gage attached to the highway bridge; installed November 21, 1903, to 

replace original wire gage read from August 18,1895, to that date. Datum of gage 

was lowered 2 feet April 3, 1897, to avoid negative readings; datum has since 

remained constant. A span of the bridge and the gage were destroyed by flood 

on the night of March 27, 1913. A temporary gage was used from April 22 to 

September 15, 1913, when a new chain gage was installed.

Channel and control. Bed of river under bridge composed of rock overlain with a 

thick deposit of mud. A rock control several hundred feet below station.

JAMES RIVER AT CARTERSVILLE, VA.

Location. At highway bridge crossing James River between Pemberton and Cartersville, about 50 miles above Richmond.

Records available. January 1,1899, to December 31, 1913. 

Drainage area. 6,230 square miles. 

Gage. Standard chain gage attached to the highway bridge July 24, 1903, to replace

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

Channel. Left bank overflows for several hundred feet at a stage of about 20 feet;

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. No measurement made in 1913, but one made

in 1914 indicated that the discharge relation, has remained constant.
JAMES RIVER BASIN. 19

ROANOKE RIVER BASIN. 

ROANOKE RIVER AT ROANOKE, VA.

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

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

1913.

Drainage area. 388 square miles. 

Gage. Standard chain gage was attached 'to Walnut Street Bridge November 28,

1903, to replace wire gage that had been read from July 10,1896, to that date. 

Channel and control. 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. Both banks may overflow at extreme flood stages. Control is loose

bowlders and shifts slightly. 

Discharge measurements. Made from 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. No

measurements were made in 1913, but measurements in 1914 indicate that the

discharge relation has remained constant. 

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

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

ROANOKE RIVER AT OLD GASTON, N. C.

Location. At 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

2£ miles above mouth of Deep Creek.

Records available. December 7, 1911, to December 31, 1913. 

Drainage area. 8,350 square miles. 

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

of second span from right end of deck-plate girder railroad bridge of Roanoke

Railway Co. 

Channel and control. Channel fairly permanent; point of control, about 1 mile

below gage, 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

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

referred to present gage datum. The corresponding discharge is about 275,000

second-feet.

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

Regulation. Persons engaged in the operation of power plants at Roanoke Rapids

and Weldon have observed on Tuesday or Wednesday during periods of low

water a trough probably due to the weekly shutdown of large power plants

farther upstream. 

Accuracy. 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.

NOTE. Daily discharge determined from a ratin? curve well defined below 33,300 second-feet and fairly 

well defined up to 181,000 second-feet. Above 194,000 second-feet the rating curve is assumed a tangent. 

Discharge Jan. 13-18,1912, estimated-because of ice. A measurement made in 1914 at a lower stage than 

any previous measurements, indicated that the curve used for discharges below 25,000 second-feet was 

not correct. Discharges for 1911-12 have therefore been recomputed and supersede those previously 

published.

NOTK. Discharge for 1911-12 supersedes that previously published.

PEEDEE RIVER BASIN. 

YADKIN EIVEE AT DONNAHA, N. O.

Location. At toll bridge in Donnaha on road between Donnaha and East Bend, 

N. C., about a quarter of a mile west of Donnaha railway station, and about 6 

miles downstream from mouth of Ararat River, which enters on left side of river. 

Station about 60 miles upstream from gaging station at Salisbury, N. C.

Records available. April 11 to December 31, 1913.

Drainage area. 1,600 square miles.

Gage. Vertical gage in four sections, on left bank 150 feet downstream from left 

end of toll bridge.

Channel and control. Channel, sand and bed rock, probably permanent. Current 

slightly obstructed by two old steel trusses lying about 150 and 400 feet, respectively, below bridge; obstructions probably permanent. Control, a rock ledge 

extending across river and forming a shoal about 450 feet below gage.

Discharge measurements. Made from 3-span toll bridge with two piers in stream 

and two on banks; bridge has steel trestle approaches at both ends. Flood water 

confined under bridge except during extreme floods above about 28 feet.

Winter flow. No ice of any importance forms at this station.

Regulation. None except for a few small milldams on tributaries.

Accuracy. Rating curve depends largely on three discharge measurements made 

early in -1914, and is moderately good between gage heights <? and 7 feet.

YADKEtf RIVER NEAR SALISBURY, N. C.

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

Southern Eailway bridge, 6 miles east of Salisbury, and about 5 miles below 

mouth of South Yadkin Eiver.

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

to December 31, 1913.

Drainage area. 3,400 square miles.
28 SURFACE WATER SUPPLY, 1913, PART II.

Gage. Standard chain gage attached to 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 back 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. Datum of the original gage at the railroad 

bridge somewhat uncertain.

Channel and control. Channel wide and rather rough; control, a rock ledge about 

500 feet below bridge, extending entirely across river.

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

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

bridge.

Winter flo-w. Ice has little if any effect at this station.

Regulation. Flow during low stages may be slightly affected by developed powers 

on the river and tributaries above station.

Accuracy. Owing to the fact that station has an excellent natural control the rating 

curve for low and medium stages is good.

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

February 21: Gage height, 2.71 feet; discharge, 3,550 second-feet.

Daily gage height, in feet, of Yadkin River near Salisbury, N. C.,for 1913.

30 SUBFACE WATER SUPPLY, 1913, PART II.

SAVANNAH RIVER BASIN. 

TALLULAH RIVER AT MATHIS, GA.

Location. About a quarter of a mile southeast of Mathis station on the Tallulah 

Falls Railway; about 900 feet below mouth of Tiger Creek, about 1 mile below 

the Mathis storage dam of the Georgia Railway & Power Co., now under construction, and about 5 miles upstream from Tallulah Falls, Ga., where a station was 

formerly located.

Records available. October 31, 1912, to December 31, 1913.

Drainage area. 186 square miles.

Gage. Step gage, composed of eight vertical sections on left bank in a line nermal 

to stream, installed March 27, 1913, about 400 feet below site of original gage 

but at same datum. Original gage had been moved 20 feet upstream February 1, 

1913, on account of construction work on bridge cribs, but was washed out during 

flood of March 16, 1913.

Channel and control. Channel fairly permanent, though owing to construction of 

bridge crib above, silt tends to collect around the gage. Bottom of sand, gravel, 

and bowlders. Control, bowlder and gravel bar about 150 feet below gage; 

practically permanent.

Discharge measurements. Usually made from a rough railroad trestle just above 

gage. Section is very rough and current irregular. One measurement was made 

by using a swinging bridge above mouth of Tiger Creek and adding measurement 

made of Tiger Creek, at a foot log half a mile above gage.

Floods. March 27, 1913; crest of flood 9.5 feet.

Winter flow. Little affected by ice.

Regulation. Small diurnal fluctuation caused by operation of small mills on Tiger 

Creek. When Mathis storage dam, 1 mile above on Tallulah River, is completed, 

the gage heights will be affected greatly.

Accuracy. Backwater from construction bridge cribs directly over original gage 

invalidates records from February 1 to March 15, 1913; readings reliable after 

March 27. Gage readings prior to February 1, 1913, probably valueless, as no 

rating curve had been made before that time.

Cooperation. Gage-height record furnished by Northern Contracting Co., builders 

of the Mathis Dam.

Discharge measurements of Tallulah River at Mathis, Ga., in 1913.

ALTAMAHA RIVER BASIN. 

OCMULGEE EIVEE NEAE JACKSON, GA.

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

mouth of Yellow Water Creek, and a short distance below Heards Creek; 1J miles 

below dam and power plant of the Central Georgia Power Co.

Records available. May 18, 1906, to December 31, 1913.

Drainage area. 1,400 square miles.

Gage. Automatic gage installed near the ferry landing on right bank by Central 

Georgia Power Co. The gage used previous to 1913 was a vertical staff In three 

sections on the right bank of river, upstream side of ferry landing. Both gages 

read the same and the staff gage is read twice a day as a check on the automatic

Channel and control. Bottom, sandy; shifts considerably but the shifting has little

if any effect on the rating curve, as the control is a rocky ledge about 400 feet

below the gage. 

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

boat held in place by the ferry cable. 

Regulation. Flow at low stages since 1911 greatly affected by operation of plant of

Central Georgia Power Co. 

Accuracy. Station fairly well rated; possible errors due to effect of power regulation

eliminated by means of automatic gage record. 

Cooperation. Gage heights furnished by Central Georgia Power Co.

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

Jun6r5: Gage height, 5.09 feet; discharge, 1,980 second-feet.

OCMULGEE RIVER AT MACON, GA.

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

bridge.

Records available. October 18, 1895, to December 31, 1913.

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 500 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 discharge relation has been considerably changed owing 

to the construction of a dock about 800 feet below the gage.

Channel and control. Both banks are high and neither is subject to overflow; bed 

soft and shifting.

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

to which the gage is attached.

Regulation. 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 curve. 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. Dredging and construction work 

below the station has so changed the discharge relation that no estimates can be 

made for 1913.

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

States Weather Bureau.

The following discharge measurement was made by B. M. Hall, jr.: 

April 3: Gage height, 7.34 feet; discharge 3,200 second-feet.

OCONEE RIVER NEAR GREENSBORO, GA.

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 1$ miles below Town 

Creek.

Records available. July 25, 1903, to December 31, 1913.

Drainage area. 1,100 square miles.

Gage. Standard chain gage attached to the bridge.

Channel and control. Bed composed chiefly of sand; slightly shifting.

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

Regulation. Flow affected by operation of power plants above station.

Accuracy. No discharge measurements made in 1913, but one made in 1914 indicated 

that there had been no change in discharge relation. Estimates of daily discharge, especially at low stages, may be somewhat in error for individual days 

. because of fluctuations due to operation of power plants.

OCONEE RIVER AT FRALEYS FERRY, NEAR MILLEDGEVILLE, GA.

Location. At Fraleys Ferry, 6 miles above Milledgeville, Ga., and about 4 miles 

below mouth of Little River.

Records available. May 23,1906, to December 31,1908; October 6, 1909, to December 31, 1913.

Drainage area. 2,840 square miles.

Gage. A combination sloping and vertical rod gage in four sections. Section 0 to 

8 feet is the old sloping gage bolted to solid rock on left bank above Fraley's Ferry. 

On November 13-14, 1913, vertical sections were added up to 20 feet.

Channel and control. Sandy and shifting at measuring section; rock control below.

Discharge measurements. Made from ferryboat.

Point of zero flow. Top of natural control is approximately 3 feet above zero of 

gage. The point of zero flow is therefore at about gage height 3 feet.

Regulation. None below vicinity of Athens, Ga., where storage may cause low 

daily discharge at this station at times.

Accuracy. Records excellent, except for high discharges, which can not be measured.

The following discharge measurement was made by Warren E. Hall and B. M. 

Hall, jr. 

November 14: Gage height, 5.39 feet; discharge, 1,370 second-feet.

OCONEE RIVER AT DUBLIN, GA.

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

Records available. February 11, 1898, to December 31, 1913; fragmentary records 

prior to 1898.

Drainage area. 4,180 square miles. .

Gage. Vertical timber attached to downstream side of central or turnspan-pier of 

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

on the right bank.

Channel and control. Rocky and nearly permanent at wagon bridge, shifting in 

bottom of channel below bridge. 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 downstream side of wagon bridge, 500 feet 

above railroad bridge.

Regulation. The only power plant of consequence is near Athens, Ga., and is so 

far above the station that its operation probably does not greatly affect the flow 

at Dublin.

Accuracy. Lack of data covering changes in channel makes results at this station 

uncertain. A good degree of accuracy may be obtained by making frequent 

discharge measurements.

Cooperation. Gage-height records since 1898 furnished by United States Weather 

Bureau.

Estimates of discharge for 1913 withheld.
FLORIDA EVERGLADES DRAINAGE CANALS. 

Daily gage height, in feet, o/Oconee River at Dublin, Ga.,for 1913.

FLORIDA EVERGLADES DRAINAGE CANALS.

During the summer of 1913 investigations of flow in the drainage canals of the Florida 

Everglades were made by the Florida Everglades Engineering Commission. In the 

course of the investigation engineers of the Commission made frequent measurements 

of Hillsboro canal, North New River canal, South New River canal, Miami canal, and 

Threemile canal, at points shown on the map (PI. III). The results of these measurements as furnished by the Commiasion are as follows:

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, 1913. 

Drainage area. 1,170 square miles. 

Gage. Standard chain gage on the toll bridge read twice daily. Original gage was

a vertical staff attached to oak tree on right bank about 100 feet above bridge.

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

gage until June 28, 1905, when present gage was installed. 

Channel and control. Bed of stream sandy and changeable; 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.

Discharge measurements. Made from downstream side of bridge. 

Regulation. Dams near Gainesville, Ga., and on Chestatee River interfere 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 excellent. 

Cooperation. Since September 1, 1912, morning gage heights have been furnished

by United States Weather Bureau.

CHATTAHOOCHEE EIVEE AT WEST POINT, GA.

Location. At Montgomery Street Bridge, West Point, Ga., until October 20, 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, 1913.

Drainage area. 3,300 square miles.

Gage. Staff gage 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; datum of staff gage different from that of chain gage formerly 

used.

Channel and control. Bottom rough, rocky, and fairly permanent; banks are overflowed at high stages; control, a rock ledge extending entirely across river just 

below gage.

Discharge measurements. Made from a boat at a section near staff gage, or from 

highway bridge to which chain gage was attached; no tributaries enter between 

the two sections.

Regulation. 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 the highway bridge. 

The new gage established in October, 1912, is not affected by backwater.

Accuracy. Rating curve well developed from low to medium flood stages. No 

records of discharge at extreme floods have yet been obtained. Diurnal fluctuation caused by hydroelectric plants above will cause some error in individual days, 

during low water.

Cooperation. Gage heights after October 20, 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.

SWEETWATER CREEK NEAR AUSTELL, GA.

Location. About 1J miles from Austell, Ga.; a quarter of a mile south of Lithia 

Springe Park; about 1£ miles downstream from Southern Railway bridge; 2 miles 

below Noses Creek; 1J miles above Stricklands bridge, and 6 miles above junction 

of Sweetwater Creek with Chattahoochee River.

Records available. May 6, 1904, to December 31,1905, and November 3 to December 27, 1913.

Drainage area. 245 square miles.

Gage. Staff gage in two sections; lower section, inclined, reading to 8 feet, is fastened 

to solid rock on right bank; upper section, reading 8 to 16 feet, fastened vertically 

to a tree on right bank about 100 feet upstream. Gage read twice daily.

Channel and control. A rocky shoal more than a mile below the gage is the apparent -control. The bottom between the gage and control is composed of silt 

which shifts and probably changes the discharge relation.

Discharge measurements. Made at Southern Railway bridge, Stricklands bridge, 

or by boat or wading near gage.

Regulation. Small water-power plants above cause considerable diurnal fluctuation 

during low stages.

Accuracy. Mean gage height for individual days, particularly during low-water 

periods, may be considerably in error owing to diurnal fluctuation.

Cooperation.- Station reestablished in the fall of 1913 by P. H. Whittier and F. K. 

McCullough, students in the Georgia School of Technology. Survey instruments 

were used and the work was directed by the district engineer.

FLINT RIVER NEAR WOODBURY, GA.

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

Ga., about a third of a mile above the mouth of Cane Creek and a quarter of a 

rnile below Elkins Creek.

Becords available. March 29, 1900, to December 31, 1913.

Drainage area. 1,090 square miles.

Gage. Vertical staff, in four sections, on the left bank about 300 feet above the railroad bridge. Datum of gage 660 feet above sea level.

Channel 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 

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

Discharge measurements. Made from downstream side of railroad bridge, which 

does not make a right angle with the current.

Regulation. The operation of power plants on tributary streams above the station 

affects the daily flow at low stages.

Accuracy. Since October 1,1912, the records are based on two gage-height readings 

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 curve was fairly constant 

for a number of years, but changed considerably in 1909 and 1910, probably owing 

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

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

of flow and necessitated the use of a new rating curve.

Cooperation. Since July 1,19J.O, morning readings have been furnished by United 

States Weather Bureau. Afternoon readings since October 1, 1912, have been 

furnished by Central Georgia Power Co.

NOTE. Daily discharge determined from a rating curve fairly well defined below 24,000 second-feet. 

Because of uncertainties due to power regulation and lack of measurements between discharges of 2,000 

and 12,000 second-feet, discharges for individual days should be used with caution.

54 SURFACE WATER SUPPLY, 1913, PART II.

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 old gage near Musella, Ga., 

 which was read for a short time in 1907.

Records available. July 1, 1911, to December 31, 1913.

Drainage area. 2,000 square miles.

Gage. Staff in four sections: Section reading 0.0 to 10.0 feet is a vertical timber well 

braced to a willow stump on left bank just below ferry landing; section reading 

10.0 to 12.0 feet is a vertical timber fastened to a sycamore tree on bank, 5 feet 

to left of lower section; section reading 12.0 to 20.0 feet is on a vertical timber 

attached to a large water oak about 50 feet to left of ferry landing; section reading 

. 20.0 to 21.0 feet is fastened directly to a large water oak 75 feet to left of ferry 

landing.

Channel and control. Bed sandy and likely to shift at station; control, rock ledge 

half a mile below; probably permanent.

Discharge measurements. Made from the ferryboat.

Accuracy. Rating curve defined by measurements for stages below 3.5 feet only; 

above that point it was extended by use of area and velocity curves; accuracy 

of estimates depends on permanence of discharge relation.

No discharge measurements were made in 1913.

Daily gage height, in feet, of Flint River near Culloden, Ga.,for 1913.

FLINT RIVER 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, 1913 (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, 1913. 

Drainage area. 5,000 square miles.
56 SUEFACE WATER SUPPLY, 1913, PART II.

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 and reads in conformity with the 

United States Weather Bureau gage.

Channel and control. Channel at and below 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.

Regulation. 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; accuracy of rating curve depends on permanence of discharge relation.

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

No discharge measurements were made during 1913.

Daily gage height, in feet, of Flint River at Albany, Ga.,for 1913.

58 SURFACE WATER SUPPLY, 1913, PART II.

FLINT RIVER AT BAINBRIDGE, GA.

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

above confluence of Flint and Chattahoochee rivers.

Records available.-^January 1, 1908, to December 31, 1913.

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

Gage. Standard chain gage attached to highway bridge.

Channel and control. Bed soft and likely to shift, but appears to have remained 

fairly permanent, as indicated by constancy of discharge relation.

Accuracy. It is possible that daily discharge as determined by one gage-height 

reading a day may be somewhat in error for individual days; otherwise the accuracy is good for low and medium stages; accuracy of rating curve depends on 

permanence of discharge relation.

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

No discharge measurements were made during 1913.

Daily gage height, infect, of Flint River at Bainbridge, Ga.,for 1913.

CHIPOLA EIVEE NEAK ALTHA, FLA.

Location. At Willis Bridge, 3J miles west of Altha, Fla., about 3 miles upstream 

from mouth of Tenmile Creek and about 1 mile upstream from Luck and Tremble 

Shoals at head of navigation.

Records available. November 21, 1912, to December 31, 1913-

Drainage area. 740 square miles.

Gage. On November 21, 1912, a vertical staff gage was placed on left bank of river 

about 75 feet upstream from bridge. On April 22, 1913, a chain gage was established on the upstream handrail of wagon bridge. Since April 22 the chain gage 

has been used.
60 SURFACE WATEB SUPPLY, 1913, PART II.

Channel and control. Rough, rocky bottom; no piers or obstructions in water. 

Current fairly swift and regular; bottom is composed mostly of soft limestone rock. 

During low and medium stages the rock shoal about 1 mile below forms an excellent control. At high stages this control is submerged and the discharge relation 

will probably be determined by the flat slope of river below the shoal. Both 

banks are steep and rocky and rarely overflow.

Discharge measurements. Made from downstream side of single span steel highway bridge. Both piers are out of water on steep banks. Measurements below 

a gage height of about 12.0 feet can be made from the bridge. Extreme floods 

can not be measured from the bridge.

Floods. Spring flood of 1912 reached gage height of about 30 feet (estimated).

Winter now. Not affected by ice.

Regulation. None.

Point of zero now. Not yet determined.

Accuracy. Data insufficient for construction of rating curve.

Cooperation. Gage heights furnished by Mr. B. H. Hardaway.

SURFACE WATER SUPPLY, 1913, PART II.

MOBILE RIVER BASIN. 

OOSTANAULA RIVER AT RESACA, GA.

65

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, 1913. 

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. 

Channel and control. 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 are made from a boat at the ferry, about 200 feet above, where

the section is somewhat better. 

^Regulation. 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 curve has been developed for low and medium stages. 

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

The following discharge measurement was made by Warren E. Hall and B. M. 

Hall, jr.: 

October 22: Gage height, 2.25 feet; discharge, 702 second-feet.

Daily gage height, in feet, of Oostanaula River at Resaca, Ga., for 1913.

MOBILE BIVEB BASIN. 67

OOOSA BIVEB AT BIVEBSIDE, ALA.

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

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

Records available. September 25, 1896, to December 31, 1913.

Drainage area. 7,060 square miles.

Gage. Standard chain gage attached to right-bank end of downstream side of railroad bridge. The original wire gage was located on the downstream side of bridge 

near middle of river.

Channel and control. Bed of stream rocky and permanent. For a part of the width 

the current is broken by a ledge above. Both banks high and do not overflow.

Discharge measurements. Made from downstream side of railroad bridge.

Regulation. 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.

No discharge measurements have been made since 1911. The accuracy of the rating 

curve depends on the permanency of the discharge relation.

Daily gage height, infect, of Coosa River at Riverside, Ala., for 1913.

ALABAMA RIVER AT SELMA> ALA

Location. At highway bridge in Selma, Ala.

Records available. January 1,1899, to December 31,1913. 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 is not thought that the discharge rating can be accurately applied further back 

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

value.
MOBILE RIVER BASIN. 69

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 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 and control. In soft limestone, deep, with swift current, and difficult to 

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

overflow at extreme high water. Discharge relation depends on an open channel 

below. No rock ledges or permanent control points are known to exist. The 

channel is mostly composed of marl, which does not shift easily, but work of 

Government dredge boats below may have some effect on the discharge relation,

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

attached.

Accuracy. As little field work has been done at this station in several years, the data 

should be used with caution.

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

No discharge measurements have been made since 1911.

Daily gage height, in feet, of Alabama River at Selma, Ala., for 1918.

NOTE. Daily discharge determined from a rating curve well defined by measurements made previous 

to 1911. As the accuracy of this rating curve depends on the permanency of the discharge relation, estimates of daily discharge should be used with caution.

MOBILE RIVER BASIN. 71

ETOWAH RIVER NEAR BALL GROUND, GA.

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

and a quarter of a mile below mouth of Longswamp Creek.

Records available. May 16, 1907, to December 31, 1913.

Drainage area. 466 square miles.

Gage. A standard chain gage, read twice each day, attached to the upstream side 

of bridge, was installed August 18, 1908, replacing the vertical-staff gage, located 

75 feet below bridge. The chain gage was set to read with the vertical staff at 

low stage, and will differ only very slightly at other stages.

Channel and control. The left bank does not overflow, but the right bank overflows about 500 feet beyond end of bridge approach at high stages. The current 

is somewhat broken and is disturbed by rough, rocky bed and curved channel 

above.

Discharge measurements. Made from upstream side of wagon bridge.

Regulation. The operation of a number of mills above may cause slight variations 

in flow.

Accuracy. The rating curve is somewhat affected by shifting of the stream bed some' 

distance below the station.

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

December 16: Gage height, 2.47 feet; discharge, 389 second-feet.

Daily gage height, in feet, of Etowah River near Ball Ground, Ga.,forW13.

ETOWAH RIVER NEAE 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, 1913. 

Drainage area. 1,800 square miles. 

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

twice each day.

Channel. Both banks subject to overflow during high water. 

Discharge measurements. Made from ferryboat or from a small boat held in place

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

Regulation. The operation of the few milldams above will seldom affect the flow. 

Accuracy. Conditions of flow are probably permanent; rating curve excellent for

low and medium stages.

No discharge measurements have been made since 1911.

Daily gage height, in feet, of Etowah River near Rome, Ga.,for 1913.

NOTE., Daily discharge determined from a rating curve well defined below 4,000 second-feet based on 

measurements made previous to 1912, Above 6,000 second-feet the rating curve is an extension. As the 

accuracy of this curve depends on the permanence of the discharge relation, estimates of daily discharge 

should be used with caution.

MOBILE BIVEB BASIN. 75

AMICALOLA EIVEE NEAE POTTS MOUNTAIN, GA.

Location. At a covered wagon bridge known as Steeles Bridge, 2 miles east of Potts 

Mountain post office, and a quarter of a mile above the mouth of Holley Creek; 

15 miles from Ball Ground, Ga., the nearest railroad station.

Records available. June 21, 1907, to December 31, 1908; June 7, 1910, to December 31, 1913.

Drainage area. 80 square miles.

Gage. Vertical staff attached to a tree on the left bank 30 feet below bridge.

Channel and control. Rocky and permanent at station, but may shift at a bar of 

small bowlders a short distance below.

Discharge measurements. Made from wagon bridge or by wading at low stages.

No discharge measurements have been made since 1911, and because of this fact 

and the possbility of change in discharge relation, estimates of discharge for 1913 are 

withheld.

76 SURFACE WATER SUPPLY, 1913, PART II.

TALLAPOOSA RIVER AT STURDEVANT, ALA.

Location. At the Central of Georgia Railway bridge a quarter of a mile west of 

Sturdevant, Ala., and 5 miles below mouth of Hillabee Creek.

Records available. July 19, 1900, to December 31, 1913.

Drainage area. 2,460 square miles.

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

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

standard chain gage installed July 10, 1905, was read until summer of 1906, when 

present gage was installed. The readings of new staff gage are all corrected to 

agree with readings of standard chain gage referred to its original datum at railroad 

bridge.

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

stage. Both banks overflow for about 200 feet at extreme high stages. Control, 

a rocky ledge across river just below bridge.

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

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

Regulation. 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 and excellent results secured at this 

station.

No discharge measurements made since 1911.

Daily gage height, in feet, of Tallapoosa River at Sturdevant, Ala., for 1913.

78 SURFACE WATER SUPPLY, 1913, PAET II.

LITTLE TALLAPOOSA RIVER NEAR WEDOWEE, ALA.

Location. Six miles northwest of Wedowee, Ala., and about 4 miles above mouth. 

Wedowee Creek enters from the south about 2 miles above station.

Records available. August 29, to December 31, 1913. Three discharge measurements were made in 1904 and referenced to a datum 0.22 foot lower than that of 

the present gage.

Drainage area. Not measured.

Gage. Vertical staff.

Channel and control. Probably slightly shifting. Control a rock ledge extending 

across the river about 1,000 feet below gage.

Point of zero flow. At about gage height 0.5 foot.

Discharge measurements. Made from a single span highway bridge about 20 feet 

below gage.

Regulation. Considerable fluctuation caused by small mills some distance above.

Data insufficient for estimate of daily discharge.

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

August 29, 1913: Gage height, 0.58 foot; discharge, 165 second-feet.

Daily gage height, in feet, of Little Tallapoosa River near Wedowee, Ala., for 1913.

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 to 1901 (discharge measurements were made by the United 

States Geological Survey and a rating was developed for those years); November 

29, 1904, to August 31, 1913. 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.

Channel and control. 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. 9

Discharge measurements. Made from downstream side of railroad bridge.

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

No discharge measurements made since 1911.

PEARL RIVER BASIN. 

PEARL RIVER AT JACKSON, MISS.

Location. At county highway bridge afc Jackson, one-eighth mile above Alabama 

& Vicksburg Railway bridge; about 5 miles above mouth of Richland Creek.

Records available. June 24,1901, to December 31, 1913.

Drainage area. 3,120 square miles.

Gage. Standard chain gage attached to highway bridge.

Channel. Channel is somewhat obstructed by old piles. Right bank high and does 

not overflow. Left bank is of clear ground and overflows for several hundred feet 

at a stage of aK,ut 20 feet. 

Discharge measurements. Made from highway bridge.

Regulation. Flow is subject to little or no regulation above or near station.

Accuracy. Some slight changes in controlling section may affect accuracy of lowwater estimates.

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

No discharge measurements made since 1911; because of this fact and the possibility

of change in discharge relation, estimates for 1913 are withheld.

SUMMARY OF DISCHARGE PER SQUARE MILE.

v

The following summary of discharge per square mile is given to 

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

areas in the south Atlantic and eastern Gu[lf of Mexico 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 0ntire 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 ba&ed 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.
