The work was begun in 1888 in cojtnection ^ith special s 

relating to irrigation in the arid West7 Since the fisdal year ending 

June 3D, 1895, successive sundry civil bills passed by Congress have 

carried the following item and appropriatioi^ ; .

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.

WATfeB SUPPLY, 1921, KABT H ; ;

made in conDyection with the description of each station affected; 

cooperation of the second kind is acknowledged on page 10. v 

Measurements of. stream flow have been made at about 5,200 points 

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

Ilawaiian: Islinis* , Jn $M& i9?l,/l;S50 gaging stations- wer^efRg 

maintained by: tW pu^fey; *&dj the cooperating oifganizationj-M plany 

miscellaneous discharge measurements are made at other pfin^sL,; In 

connection with this, work data were also collected in regard to * 

cipitation, evaporation, storage reservoirs, river profiles, and 

power in'malay sections bf'tne country andwill be niader available in 

;water-supply papers frpjn time to time.

The volume of water fldwiri^in. a stream the "run-off" or "discharge" is'expressed in various[terms,each pi which has become 

associated with a certain class of work; The terms may be divided 

into' two groups (1) those that represent a rate of flow, as:seeondfeet, gallons per minute;; miners' inches, and discharge itt sedpiif(ifeet per square mile, and (2) those that represent the actual ^i^ri^f 

of water, as run-off in inches, acre-feet, and millions of cubic, feet. 

Tne principal terms' used in this series of reports are seeoricl-' 

secphd-feet per square mU,e, ^run-'on* ill inches, an'd 4cre-feel. if! 

may be defined as fpjjp^^ , « .

" Second-feet" is an aoDreviation for'" cubic feet per 

A second-foot is the rate '$£ diseh'arge'''of water flowing in a channel 

of rectangular bro^^sebtii'bh'i'^^^id^ ah& 1 foot deep at wti'at^e 

velocity of 1 foot per second. It is generally used as a i 

unit from which others are computed.

"Second-feet per square mile" is the average,iiumber of ctibic 

of water flowing per second .from each, square mile of ares; drained$ I 

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

regards'time and area. " ^

"^un-pff in inches" is the depth to which an area wdul^be covered if all the water flowing £rpm it in a given period werefpiiformly 

distributed . 01 Jthe, surface. It, is used for comparing run«off 

rainfell^ which is usually expressed in inohes. >"' .

An '* acre-foot," equivalent to 43,560 cubic feet, is thf; tfua 

required to cover an acre to the depth of 1 foot. The terra* is commonly, use4 i» connection^ with storage for irrigation. - ;f

f xlaily discharge gives, to g^rieifftly1 the discharge fe

day, At sta&cta8 OI1 ^steeams .subject to sudden or rapid 'diirnal 

fluctuations fee discharge obtained from the rating table and? *h© 

mean daily gage -height may not be the true mean discharge fo® the 

day. If such stations are equipped wittx water-stage recorders the 

mean daily discharge may be obtained by averaging disctiarge at 

regular intervals during the day or by using the discharge inte^aftoy, 

an instriament operating on the principle of the planimeter and containing as an essential element the rating curve of the station. '

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

gives the mean flow for the day wheti the mean gage height was 

highest. As the gage height is the mean for the day it does iSot 

indicate :cbrrectly the stage when the water surface was at crest 

heigh* and the corresponding discharge was consequently larger 

than given in the maximum Column; tike wise, in 'the column 

headed "Minimum" the quantity given is the mean flow for the day 

when the meaii gag6 height was lowest. The column headed 

'^Mean" is the average flow in cubic feet for each se^bntf1 (luting 

the month. On this average flow commutations recdifded ln; the 

remaming columns which" are defined ott pages 2 and S, s arer bas&l.

accuracy of stream-flow data depends primarily (1) ott tne 

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

of observation of stage, measurements of flow, and intef pretAtibi^ of 

records.

A paragraph in the description of the station or footnotes added 

to the tables gives information regarding (1) the permanence oi the 

sta^-discharge relation, (2) precision with which the discharge 

i*ating curve is defined, (3) refinement of gage readings, (4) i, re- 

<|«ency of gagci reading, and (5) methods of applying daily 

heists to the rating table to obtain the dkily discharge.1

The records at most of the stations discussed in these reports 

extend over a series of years, and miscellaneous measurements at 

many points other than regular gaging stations have been made 

each year. An index of the reports containing records obtained 

prior to 1904 has been published in Water-rgupply Paper 119.

The following table gives, by years and drainage basins, the numbers of the papers on surface-water supply published from 1899 to 

1921. The data for any particular station will be found in the 

reports covering the years during which the station was maintained.

of Thelma, and 2% miles above mouth of Deep Creek. 

DBAINAGE ABEA. 8,350 square mil^s. " 

 EECQBDS AVAILABLE. December 7, Ifttl,, to September 80,1921. 

0AGB,r Chain gage attached to outside guard .timber on dowijstream side of

second span from right end of deck railroad bridge; read by E. A. BtoweH.
16 SURFACE WAT1B SUPPLY, 1921, PART II

DISCHARGE MEASUREMENTS. Made from downsteeam side of the bridge. 

Measuring section broken by 11 bridge piers. This bridge has been floored 

over and equipped with handrails. It is now a combined toll highway 

and railroad bridge.

CHANNEL AND CONTROL, Channel practically permanent Control about 1 milebelow gage is of rocks and probably permanent Left bank subject to 

overflow in extreme floods, bat a fair determination can be made of the 

overflow discharge around bridge.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 9.7 feet at 

7.25 a. m. December 3 (discharge, 59,700 second-feet) ; minimum stage, 

1.00 foot at 7.30 at, m. August 27, 28, 30, 31, September 1-3 and 8 (discharge, 890 second-feet).

1911-1921: Maximum stage recorded, 16.6 feet at 7 a. m. March 18,. 

1912 (discharge, 210,000 second-feet) ; minimum stage, 0,95 foot at 6 a. m. 

October 1, 1914 (discharge, 790 second-feet).

ICE. Ice forms to considerable thickness at this station during severe winters, 

and the stage-discharge ^relation is seriously affected.

REGULATION. During periods of low water there are variations in flow, probably due to weekly (Sunday) shutdown of large power plants farther upstream. These variations are observable at power plants at Roanoke 

Rapids and Welcton on Tuesdays or Wednesdays.

ACCURACY. Stage-discharge relation practically permanent; not affected by iceduring the year. Rating curve revised slightly on basis of recent measurements atid is well defined below 33,000 second-feet and fairly well defined 

to 200,000 second-feet Gage read to tenths once daily. Daily discharge 

ascertained by applying daily gage height to rating table. Records

The following discharge measurement was made by Stevens and Dirzulaitist 

June 21, 1921: Gage height, 2.38 feet; discharge, ,4,410 second-feet

AT DONKAHA, **(«.,» *,< ;4 ^-, : i ^^'u^;',

LOCATION. One-fourth mile upstream from railroad station at Donnaha, 

Forsyth County, Just below site of old toll bridge whicft was washed 

away by a flood in 1916, 6 miles downstream from Ararat River, which 

enters from left ...

DBAINACW: ABEA. 1,600 square miles. ;

Rtecoms ' AVAn^REJk April 11, 1913, to September 30, 1918, and October ,1,

1920, to September 30, 1921. : 

' GAGE. -Vertical gage in four sections on left bank, 160 feet downstream frojai 

left «nd of remains of old toll bridge1 ; read by 3. F. Goolsby. Section <£ 

gage below 10 .feet, which was carried away by ice in February, 1918, was 

replaced April 23, 1920.

DISCHARGE MEASUEEMENTS. Prior to flood in July, 1916, measurements were 

made from toll bridge. Bridge washed out |n July, 1910. After that 

date no measurements were made until April 23, 1920, when a new; bridge 

had been erected 1 mile downstream. Since July, 1920, measurements 

have been made from a cable erected 400 feet upstream jfrom gage by 

North Carolina Geological & Economic Survey.

CHANNEL AND CONTEOL. Bed composed of sand and bedrock; probably permanent Current slightly obstructed by two old steel trusses one of 

which is opposite and the other 300 feet below gage; obstruction probably 

permanent Control is a rock ledge extending across river and forming a 

shoal 450 feet below gage.

EXTREMES OF DISCHARGE, Maximum stage recorded during year, 14.5 feet lit

 10 a. m. April 17 (estimated discharge, 19,200 second-feet); minimum

stage recorded, 5.4 feet numerous periods in September (discharge,

second-feet).

1913-1921: Maximum stage recorded, 40.0 feet at 8 a. m., J^y 3^ 

(determined hy observer who measured from flood marks down to wa<;er 

surface at lower stage; discharge not determined); minimum stage, 4.65 

feet at 4 p. m. September 30, 1914 (discharge, 678 second-feet).

ICE. Stage-discharge relation not Effected by ice.

DIVEESION. None.

REGULATION. None except for a few small mill dams on tributary streams.

ACCTJBACT. ^Stage-discharge relation practically permanent. Eating curve 

well defined below 2,500 second-feet and fairly well defined between 2,500 

and 15,000 second-feet; extended above 15,000 second-feet Gage read to 

tenths twice daily. Daily discharge ascertained by applying mean, daily 

gage height to rating table. Records fairly good.

From the date of establishment'to Hay&31, 1899, the gage -was at the

, been, at-., the highway bridge; the datum originally established there in

l§90vtiae never knowingly been changed; bjjt it is, probable that there has

been a variation of about 0.1 foot owing to settlement of bridge or other

cause. On Jttly 19, 1921, gage was moved from middle of long span to a

ARARAT RIVER NEAR PILOT MOUNTAIN, N. C.

LOCATION. At steel highway bridge on Ararat Road, R D. route 3,1 mile below 

mouth of Tom's,Creek} 1% miles upstream from old Douglas Ford, and 5* 

miles west of Pilot Mountain, Surry County. ;./

DEAINAGE ABEA. 250 square miles. .... . '': ....'_ ......

RECOEDS AVAILABIJE, Jfuly 28,1920, to September SO,1Q21. , ;

GAGE. Enameled staff .gage fastened to downstream side of pier at left bankr 

..read by Martin A. Fulk, . . .

DISCHARGE MSASUEEMENTS. Made from downstream side of highway bridge to* 

which gage is attached.

CHANNEL AND CONTBOL. Channel is straight and. smooth above and below gagec 

Banks are about 10 feet high and rarely overflowed. Control is a rode 

shoal about 75 feet downstream from gage; excellent for stages below 10» 

feet. Rock bluffs farther downstream make high-water control.

EXTREMES OF DISCHABGE. Maximum stage recorded during period of records, 

6.2 feet at 7 a. m. December 14, 1920 (discharge, 5,040 second-feet) r 

minimum stage, 0.30 foot at 8 a. m. September 20, 1921 (discharge, 70* 

second-feet).

ICE. Probably not enough to affect stage-discharge relation. '

REGULATION.-*-TWO hydroelectric power plants above station may seriously 

affect the low-water flow; their storage however is relatively small.

ACCUBACY. Stage-discharge relation permanent. Rating, curve well defined! 

between 1 5 and 2,550 second-feet and extended beyond these limits. Gage* 

read to httndredths twice daily. Daily discharge ascertained by applying; 

mean daily gage height to rating table. Records good. ;

OCMULGEE RIVEK AT JtTLIETTE, GA.

LOCATION. 1 mile below Juliette railroad station, I mile below Juliette cotton 

'' mills, which are on left Side of river opposite Juliette, and 2^ miles 

below mouth of Towaliga River.

DRAINAGE ABEA. 2,10Q square miles (measured on pt>st-rcfate map).

BECOB0S AVAILABLE. June 3, 1916, to September 12, laS!!^ when station was 

discontinued.

GAGE. Stevens continuous water-stage recorder; in concrete stilling well on 

left tank of river. , ;' :

DISCHABGK MEASUREMENTS. Made from a cable 150 feet, upstream from gage.

CHANNEL ANO CONTROL. Bed composed of sand and solid rock at gage section. 

Banks high; subject to overflow at gage height of about 16 feet. Control 

is a rock ledge across bottom of river 600 feet below; jfage, and a rock 

shoal about half a mile downstream forms a control which keeps stagedischarge relation permanent. , EXTREMES os* DISCHARGE. Maximum stage recorded during year 22.84 feet at 

12.15 a. m. February 11 (discharge, 38,800 second-feet) ; minimum stage, 

3.60 feet at 1.80 p. m. May 2 (discharge, 710 seco^f^ettr). . (

1916-1921: Maximum stage recorded 30.8 feet from 9 to 11 a. m. December 11, 1919 (discharge, 52,900 second-feet) ; minimum stage from 

water-stage recorder, 2.74 feet from 4 to 5 p. m. November 4, 1918 (discharge, 270 second-feet from extension of rating curve). Minimum stage 

caused by regulation at Jackson dam.

A stage of 82 feet was probably reached by the*1 flood in 1886. This 

stage was determined by marks pointed out by residents and may be subject to error. Discharge corresponding to this stage is about 55,800 

second-feet.
32 SURFACE WATER SUPPLY, 1921, PART H

DIVEBSIONS. None.

REGULATION. Considerable fluctuations in stage are caused by operation of 

the hydroelectric plant about 20 miles upstream, near Jackson, Ga. Minor 

diurnal fluctuations are caused by operation of Juliette mills, 1 .mile upstream, and the hydroelectric plant on Towaliga River at High Falls, 

about 15 miles away.

ACCTTBACY. Stage-discharge relation probably permanent. Rating curve well 

defined between 600 and 25,000 second-feet and fairly well defined between 25,000 and 45,000 second-feet; extended above 45,000 second-feet. 

Gage did not operate satisfactorily during periods indicated in footnote 

to daily-discharge table. Daily discharge determined by use of discharge 

integrator. Records good. ;.'

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

Hall, jr.: 

May 25, 1921: Gage height, 4.87 feet; discharge, 1,700 second-feet.

HECOBDS AVAILABLE. July 25, 1903, to September 30, 1921.

^AGE. Chain gage attached to bridge; read by N, T. Oakes. Since July 21, 

1919, when bridge was repaired, gage has read 0.1 foot too high, but readings have been corrected for this error.

DISCHABGE MEASUBEMENTS. Made from downstream si&e of bridge. .,

CHANNEL AJ*B CONTBOL. Bed composed chiefly of saad, slightly shifting. Control section not known, but practically permanent.

EXTBEMES OF DISCHABGE. Maximum stage recorded during year, 20.6 feet, at 4 

p. m. February 11 (discharge, 25,400 second-feet); mlnimrim stage recorded, 

0.5 foot at 4 p. m. September 16 (discharge, 205 second-feet).

1903-1921: Maximum stage recorded, 85.4 feet August 26, 1908 (discharge, about 70,000 second-feet; revised determination) ; minimum stage, 

0.2 foot in forenoon ,of July 15, 1918 (discharge, 141 second-feet).

ICE. None.

DIVERSION s. None.

jREGUtATiON. Considerable diurnal fluctuation caused by operation of power 

plants.

ACCURACY. Stage-discharge relation practically. permanent No discharge 

measurements have been made since 1919. Eating curve well defined 

between 250 and 6,000 second-feet; extended above 6,000 second-feet "on 

basis of area and mean velocity curves and the discharge for crest of flood 

on December 11, 1919, as computed, using concrete dam at Athens as 

weir and correcting for difference in drainage area. Bating curve has 

not been checked by current-meter measurements since July 26, 1019. 

Gage read to tenths twice daily. No corrections for possible elongation, 

of gage chain since July 26, 1919, have been made. Daily^ discharge 

ascertained by applying mean daily gage height to Tatlng'table. Records 

fair. . /

APALACHICOLA RIVER BASIN 

CHATTAHOOCHEE EIVER NEAR WOROROSS, GA.

At Medlock's Bridge, 1% miles upstream from mouth of John 

Creek, 4% miles north of Norcross, Gwinnett County, 5 miles below 

Suwann^e Creek, 17 miles upstream from Bull Sluice dam, 30 miles below 

mouth of Chestatee River, and 35 miles below Dunlap dam.

DBAINAGE ABEA. 1,1TO sqsare miles.

RECOBDS AVAILABLE. January 9, 1903, to September 30, 1921.

GAGE. Chain gage on toll bridge; read by W. O. Medlock. January 1 to September 30, 1916, a Dexter waiter-stage recorder on right bank just above 

bridge, and referred to chain gage without change in datum, was also used 

for recording stages below 7 feet. See "Regulation."

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

CHANNEL AND CONTBOL. Bed sandy; shifts. Control is a rock shoal about 2% 

miles downstream and is more pronounced for higher stages than for low. 

Medium stages are affected somewhat by shifting bottom conditions 

between gage and rock shoal. However at extremely low stages control 

seems 'to be practically permanent.

EXTBEMES OF DjscHABGB. Maximum stage recorded during year, 20.4 feet at 

6 p. m. February 10 (discharge, 33,300 second-feet) ; minimum stage, 1.4 

feet at 7 a. m. September 25 (discharge, 720 second-feet).

1903-1921: Maximum stage recorded, 27.1 feet at 3 p.. m. December 10, 

1919 (discharge, 54,700 second-feet) ; minimum stage, 1.02 feet October 21, 

1911 (discharge, 294 second-feet). It is believed that this low stage was 

caused by shutting off flow at the two power dams near Gairiesville, Ga.
BASIH

ICE. Never enough to affect stage-discharge Delation. ,; f 

KEGULATION. Diurnal fluctuation is caused by operation of hydroelectric 

plants on Chattahoochee and Chestatee rivers near Gainesville, Ga. 

Monthly discharge, January to September, 1916, determined" froia jeeeords 

of water-stage -recorder, agreed very closely with that obtained by using 

.mean daily gage heights from two readings of chain per day, indicating 

that monthly discharge obtained by using records from chain gage is not 

seriously in error. See Water-Supply Paper 472, p. 34.

AcctJEAcrr. Stage-discharge relation practically permanent during the year. 

Rating curve well defined between 800 and 55,000 second-feet. Gage rf^Ml 

to hundredths twice daily. Daily discharge ascertained by applying meatf 

daily g^ge height to rating table. Records good. '.- Vi/

CHATTAHOOCHEE RIVER AT WEST POINT, OA.

LOCATION. At West Point waterworks pumping plant, just below Oseligee 

Creek, one-fourth mile east of Alabama-Georgia State line, in Troup^ 

County, and 1 mile upstream from West Point railroad station. Prior to 

October 20, 1912, station was at Montgomery Street Bridge in West Point.

DRAINAGE ABEA. 3,300 square miles.

RECORDS AVAILABLE. July 30, 1896, to September 30, 1921.

GAGE. Original gage was a chain on downstream handrail of Montgomery 

Street Bridge. On October. 20, 1912, the gage was moved 1 mile upstream 

to a point opposite city pumping plant. A staff gage (0-18 feet) was 

placed on left bank. This gage was read from October 20, 1912, to December 10, 1919, by using a telescope from pumping station which is on 

right bank. The flood of December 10, 1919, put the gage out of commission. On January 14, 1920, the rod on left bank was replaced but 

could not be read below 6 feet because of a sand bar formed by flood. 

A short section of rod (0-6.7 feet) was located on right bank. Both rods, 

were set to same datum but the right-bank section reads slightly higher 

than the left-bank section. Since January 14, 1920, the observer has read 

right-bank gage during stages below 6 feet and left-bank gage for stages 

above 6 feet. The observer is Mr. J. H. Miller.

DISCHARGE MEASUREMENTS. Made from the Montgomery Street Bridge 1 mile 

downstream. No tributaries enter between gage and bridge. Bridge 

washed away December 10, 1919, and replaced by a new one before this 

year's measurements were made. Measurements have sometimes been 

made from the Atlanta & West Point Railroad bridge.

CHANNEL AND CONTROL. Bed rough and rocky; fairly permanent. Banks sub5 

ject to overflow at high stages. Control is a rock ledge extending across 

river just below gage and is not affected by Langdale dam 5 miles downstream.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 19.3 feet at 

5 p. m. February 10 (discharge, 53,000 second-feet) ; minimum stage 

recorded, 2,25 feet at 7 a. m. September 21 (discharge, 1,OBO second-feet). 

1896-1921: Maximum stage recorded, 30.0 feet at 2 p. m. December 10, 

1919 (discharge, 134,000 second-feet) ; minimum stage recorded (old 

gage), 0.8 foot September 18-21, 1896 (discharge, 780 second-feet).
ICE. None.

DIVERSIONS. None.

BEGULATION. Operation of power plants a great distance upstream causes 

some diurnal fluctuation.

AcctrnACY. Stage-discharge relation permanent since December 10, 1919. 

Eating curve well defined between 1,000 and 60,000 second-feet; above 

60,000 second-feet the curve is extended on basis of the discharge computed for the crest of the flood on December 10, 1919, using the Goat 

Hock dam, 12 miles above ColumBus, as a weir and correcting for difference in drainage area. Gage read to tenths twice daily; during high 

water oftener. Daily discharge ascertained by applying mean daily gage 

height to rating table. Records good.

FLINT RIVER NEAR WOODBTJRY, GA.

LOCATION. At Macon & Birmingham Railroad bridge one-fourth mile downstream from mouth of Blkins Creek, one-third mile upstream from mouth 

of Cane Creek, and 3 miles east of Woodbury, Pike County.

DRAINAGE AREA. 1,090 square miles;

RECORDS AVAILABLE. March 29, 1900, to September 30, 1921.

GAGE. Chain gage attached to guardrail on downstream side of Macon & Birmingham Railroad bridge; installed May 24, 1918. Prior to that date gage 

was a vertical staff in four sections on left bank about 300 feet above 

present gage. Gages set to same datum. Slope between gages negligible 

at low and medium stages since the low wagon bridge immediately below 

the old staff gage was washed out in July, 1916. Zero of gage, 660 feet 

above sea level. Gage read twice daily by E!. T. Riggins.

DISCHARGE MEASUREMENTS. Made from downstream side of railroad bridge 

which does not make a right angle with the current.

CHANNEL AND CONTROL. Bottom consists chiefly of rock; rough; current irregular. Control formed by a shoal 1 mile downstream; shifts occasionally.

EXTREMES OP STAGE. Maximum stage recorded during year, 10.0 feet at 5 p. nu 

February 11; minimum stage recorded, 0.18 foot at 7 a. m. and 5 p. m. 

September 26.

1900-1921: Maximum stage recorded, 17.1 feet at 7 a. m. December 11, 

1919 (discharge, 38,400 second-feet) ; minimum stage recorded, 0.4 foot 

October 8-10, 1911 (discharge, 86 second-feet).

J<:E. None.

DIVERSIONS. None.

RTEGXJLATION. Some slight diurnal fluctuations caused by operation of small 

mills on tributary streams. '

, No determinations of discharge have been made, as the rating curve has not 

Neen verified by discharge measurements since September 20, 1919.

FLINT RIVER NEAR CULLODEN, GA.

LOCATION. At Grays Ferry, Upson County, 1% miles upstream, from mouth 

of Auchumpkee Creek and 14 miles southwest of Culloden.

DRAINAGE AREA. 2,000 square miles.

KECORDS AVAILABLE,' July 1, 1911, to September 30, 1921.

GAGE. Original gage was a staff in four sections on left bank at old ferry 

landing. In August, 1918, a Stevens continuous water-stage recorder 

with a standard wooden well and shelter was installed on left bank about 

100 feet upstream from old rod gage; the Stevens gage was replaced by a 

Gurley 7-day graph recorder on May 29, 1919. Gage inspected by Arthur 

Preston.

DISCHARGE MEASUREMENTS. Made from rowboat held in place by a small galvanised cable stretched taut across river.

CHANTSEL ANii cQNTKOL.-^Channel sandy and shifting at gage. Control is a rock 

ledge half a mile downstream; fairly permanent. /

EXTREMES OF DISCHARGE. Maximum stage during year, 19.4 feet at 8 a. m. 

February 11 (discharge, 29,800 second-feet) ; minimum stage, 1.34 feet 

from 2 p. m. September 27 to 2 a. m. September 28 (discharge, 270 secondfeet).

1911-1921: Maximum stage recorded, 33.3 feet during night of July 9, 

1916 (discharge not determined); minimum stage recorded, 1.0 foot 

October 8, 1911 (discharge, 165 second-feet).
46 SUBFACE WATEE SUPPLY, 1921, PART II

ICE. None. . ,

DIVERSIONS. None.

ACCURACY. -Stage-discharge relation practically permanent. Rating curve 

well defined between 250 and 5,000 second-feet; extension above 5,000 

second-feet based on discharge at crest of floods,at Woodbury corrected 

for difference in drainage area. Operation of water-stage recorder unsatisfactory owing to frequent stopping of clock, but observer read rod gage 

when clock was not running. Diurnal fluctuation at this station is negligible. Daily discharge ascertained by applying mean daily gage height to 

rating table. Records good except for extremely high stages.

No discharge measurements were made at this station during the year.

FLINT RIVER AT ALBANY, OA.

LOCATION. At Dougherty County highway .bridge in Albany, 700 feet below 

Atlantic Coast Line Railroad bridge and 2 miles downstream from mouth 

of Muckafoonee Creek.

DRAINAGE AREA. 5,000 square miles.

RECOBDS* AVAILABLE. April 10, 1893, to June 30, 1921, when station was discontinued. (United States Weather Bureau gage heights). Discharge 

measurements were begun by the Geological Survey in 1901 and determinations of daily discharge have been made since January 1, 1902.

<*AGE. Chain gage installed at the bridge April 20, 1904; read daily by D. 

W. Brosnan. Original staff gage washed out in 1898. It was again damaged in 1902 and on June 18 of that year a new gage was installed by 

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

of the former gage. All gage heights published for 1902 by the United 

States Weather Bureau and the United States Geological Survey refer 

to the new datum. Present gage contorms with the United States Weathetf 

Bureau gage.

DISCHABGE MEASUREMENTS. Fairly accurate measurements can be obtained at 

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

and train switching in the 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.

CHANNEL AND CONTEOL. Channel at and below gage may shift slightly but 

control is such that conditions of flow are practically permanent. The 

river overflows both banks but only under approaches to the bridge.
48 SURFACE WATER SUPPLY, 1921, PART II

EXTREMES OF BISCHABGE. Maxtmram stage during year, 17.3 feet February i8t 

(discharge, 26,200 second-feet) -, minimum stage, 0.0 foot October 21, 

June 14 and 21 (discharge, 2,180 second-feet).

1902-1921: Maximum stage recorded, 30.3 feet at 7 a. m. March 21, 

1913 (discharge, 53,700 second-feet) ; minimum stage recorded, 1.1 feet 

October 9-12, 1911 (discharge, 1,110 second-feet).

A stage of 32.4 feet occurred on March 25, 1897 (discharge, GS.OOO' 

second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

REGULATION. Power development on Muckalee Creek, which joins Flint Biter 

about 2 miles above the station, causes considerable diurnal fluctuation, 

especially at low stages. The flow is probably also affected by other powe* 

plants farther tip the river.

ACCURACY. Stage-discharge relation practically permanent. Rating curve 

well defined between 1,800 and 00,000 second-feet. Gage read to tenths 

once daily. Daily discharge ascertained by applying daily gage height 

to rating table. Records fair; discharge for low stages as determined 

from one reading of gage daily ma^ be somewhat in error owing to fluctuations in stage caused br operation of power plants on tributary streams 

above the station.

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

March 29, 1921: Gage height, 2.87 feet; discharge, 4,520 second-feet.,

Daily discharge, in second-feet, of Flint River at Albany, Oa., for the period 

Oct. 1, 1920, to June SO, 1921 '

is swift and broken. Banks fairly high but subject to overflow during 

extremely high stages. Bed of stream mostly rock and gravel.

EXTBEMES OP DISCHARGE. Maximum stage recorded during year, 27.5 feet at 

4 p. m. February 10 (estimated discharge, 20,100 second-feet, determined 

from rating curve extended above 6,000 second-feet) ; minimum stage, 

1.50 feet at 7 a. m. September 5-7, 9-11, 14-17, 25, and 30 (discharge, 

505 second-feet).

ICE. Practically none.

DIVERSIONS. None.

REGULATION. Operation of a few small mills on tributaries probably has no 

effect on stage at the gage.

ACCURACY. Stage-discharge relation probably permanent but no measurement* 

have been made since February 6, 1920. Rating curve previously developed fairly well defined between 500 and 3,000 second-feet; extended 

above 6,000 second-feet. Gage read to tenths once daily. Daily discharge ascertained by applying daily gage height to rating table. Records 

fair except those for stages above 6,000 second-feet which are subject

C008A RIVER AT CHILDERSBTTRG, ALA.

LOCATION. At Central of Georgia Railway bridge half a mile west of Childersburg, Talladega County, 35 miles above site of Lock 12, and 75.3 miles 

above Wetumpka. v

DBAINAGE ABEA. 8,390 square miles (determined by Alabama Power Co.).

RECORDS AVAILABLE, February 22,' 1914, to September 30, 1921.

GAGE. Gurley printing water-stage recorder attached to downstream end of, 

second pier from right bank of river; installed May 5, 1914. Prior to that 

date readings were taken from a vertical staff gage fastened to upstream 

side of same pier to which Gurley gage is now attached. Datum of Gurley 

gage Is about 0.1 foot higher than that of the staff gage. This difference 

in datum is believed constant since 1914. All records from 1915 to 1921 

are referred to datum of Gurley gage. Sea-level ^elevation of zero of staff 

gage is 421,00 feet (United States Engineer Corps datum).

DISCHARGE MEASUREMENTS. Made from bridge.

CHANNEL AND CONTROL. Channel straight for half a mile below gage. Left 

bank high; right bank subject to overflow at extremely high stages. Control not well defined; bed of stream probably permanent.

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

corder, 20.3 feet at 6 a. m. February 12 (discharge, 92,500 second-feet); 

minimum stage, 1.3 feet at 11 a. m. September 24 (discharge, 2,520 second1914-1921: Maximum stage from water-stage recorder, 24.7 feet from 

3 to 9 and 11 to 12 p. m. July 11, 1916 (discharge, 121,000 second-feet); 

minimum discharge, 2,370 second-feet, September 20, 1914.

REGULATION. None.

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

defined between- 3,000 and 70,000 second-feet; extended above 70,000 secondfeet Operation of water-stage recorder satisfactory except as indicated 

Jn footnote to table of daily discharge. Daily discharge ascertained %.; 

applying to rating table mean daily gage height obtained by averaging
60 SURFACE WATER SUPPLY, 1921, PART II

hourly gage height. Records good below 70,000 second-feet; fair above 

that point. 

COOPEEATION. Gage-height record furnished by Alabama Power Co.

No discharge measurements were made at this station during the year.

Daily discharge, in, second^feet, of Coosa River at Childersbwg, Ala., for the 

year ending Sept. 80, 1921

LONGSWAMP CREEK NEAR BALL GROUND, GA. '

LOCATION. At wooden wagon bridge half a mile upstream from mouth of 

creek that enters Etowah River one-fourth mile above gaging station on 

that river. Bridge is 2 miles southeast of Ball Ground, Cherokee,H County.

DRAINAGE AREA. 74 square miles (measured on topographic maps).

RECOEDS AVAILABLE. November 30, 1018, to June 80, 1921, When' the Station 

was discontinued.

GAGE. A vertical rod with enameled face, spiked to downstream post of lefthand bridge bent; read by Mrs. H. J. Wheeler.

DISCHABGE MEASUREMENTS. Made from downstream side of 3-span wooden 

wagon bridge to which gage is attached.

CHANNEL AND CONTROL. Channel straight for several hundred feet above and 

below bridge. Bed smciioth and sandy; section very shallow at low water; 

current swift. Control is formed by a gravel and boulder shoal 300 feet 

downstream. Though gage is only half a mile above junction with Etowah 

River it is believed that there is seldom backwater from the river, as 

there seems to be considerable fall on creek below gage.

EXTREMES OF DISCHABGE. Maximum stage recorded during year, 17.3 feet at 

8 a. m. February 9 (discharge, 3,490 second-feet) ; minimum stage recorded, 

0.7 foot at 8.30 a. m. June 10 (discharge, 70 second-feet).

1919-1921: Maximum, stage recorded, 17,5 feet at 7 a. m. December 

22, 1918 (discharge, 8,&40 second-feet) ; minimum stage recorded, 0.18 foot 

at 7 a. m. September 26-30, 1919 (discharge, 22 second-feet). .,

ICE. None. : > ' ' . . . :,: DIVERSIONS. None. .,' . < , 

REGULATION. Though there is one or ntore small water-power plants upstream; 

the daily fluctuation seems to be negligible. ' 

ACCURACY. Stage-discharge relation j^obably permanent. Rating curve welt 

defined between 30 attd 800 second-feet; extended above 800 second-feet 

on basis of run-off of Etowah River near Ball Ground. Gage read to 

hundredth^ once dally. Daily discharge ascertained by applying daily 

, gage height :to rating table. Recdrds good except those for stages 

800'second-feet'Which are subject to error.

JSAGE. Vertical staff, 0-24 feet, on right bank 2,000 feet upstream from 

Bridge; installed August 20, 1906; read by A. L. Stow. Original gage, a 

staff attached to pier of railroad bridge and later a chain gage on railroad 

bridge, was read Until July, 1905, when the present gage was substituted 

for the chain gage because it was impossible to obtain an observer for 

gage at bridge. From August 21, 1906, to,September 30, 1915, readings on 

the present staff gage were reduced to datum of original gage by means' 

, of comparative readings. Since October 1, 1915, gage heights have beeiii! 

obtained from readings on the present staff gage without reference tcr 

datum of old gage which has been removed, and a new rating has beent 

made based on presold; gage datum. ; . -,,.

DISCHABGE MEAStTEEiiENTS. Made from a plank walk resting on lower members of deck of railroad bridge.

CHANNEL AND CONTBOIJ. Bed rough and rocky; permanent. At extremely high, 

stages water overflows-banks but is confined entirely under bridge. COB* 

trol is a series of rock ledges, shoals, and bluffs below bridge; permanent*.

October 25-29, 1904 (discharge, 250 second-feet).

ICE. Stage-discharge relation not affected by ice.

REGULATION. Practically none.

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

between 300 and 30,000 second-feet; extended above 8^,000 second-feet on 

basis of crest run^bff of Chattahoochee River during flood of December 11, 

1919. Gage read to hundredths twice daily. Daily discharge ascertained 

by applying mean,daily gage height to rating table. Records good.
