AUTHORIZATION ANB SCOPE OF WOBSTi

This volume is one of a series of 14 reports presenting' iresuli& of 

measurements of flow made on; streams in the United States during 

tjxe year ending September 30, 1921.

jrtie data presented in these reports were collected by the United 

States Geological Survey under the following authority contain^ in' 

the organic law (20 Stat. L., p. 394); ' '

Provided, That this officer [the Director] shall have the .direction of the Geological Survey and the classification of public lands and examination' bf th<^ 

geological structure, mineral resources, and products of the national domain. '

The work was beguri in 1888 in cpnneqtion with special, studies 

relating to irrigation in the aricl -Wes.t. Since the fiscal y*ear endling 

June 30, 1895, sucessive sundry civil bills passed by Congress .have 

carried the following item and appropriations:, - ^ ,,,

1 $er gaging itae, sta-eams and deternaiBfaag ibhe water supply, of ;th^- yjE$»d 

States, and for the investigation of .underground currents and arterian weps^ 

and for the preparation of reports upon the best methods of utilizing the wafer 

resources.

daily discharge may be obtained -by' Averaging discharge at regular 

intervals during the day or by using the discharge integrator, , an 

instrument operating on the principle of the planjmeter 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 when the mean gage height waa 

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 headed 

"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 

average flow, computations recorded in the remaining columns, which 

are defined on pages 4 and 5, are based.

ACCURACY OP FIELD DATA AND COMPETED

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

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

observation of stage, measurements of flow, and interpretation ojt 

records. , f ,, r _ A paragraph in the description of the station or footnotes added to 

the tables gives information regarding (1) the permanence of the 

stage-discharge relation, (2) precision with which the discharge rating 

curve is defined, (3) refinement of gage readings, (4) frequency of 

gage readings, and (5) methods of applying daily gage heights to the 

rating table to obtain the daily discharge. V

For the rating tables "well defined" indicates, in general, that the 

rating is probably accurate within 5 per cent; "fairly well define^," 

within 10 per cent; "poorly defined," within 15 to 25 per <Qent. 

These notes are very general and are based on the plotting of tiie 

individual measurements with reference to the mean rating curve.

The monthly means for any station may represent with high accuracy the quantity of water flowing past the gage, but the figures 

showing discharge per square mile and depth of run-off in inches 

may be subject to gross erjors caused by the inclusion of large noncontributing districts in the measured drainage area, by lack of 

information concerning water diverted for irrigation or other useiv 

or by inability to interpret the effect of artificial regulation of, the 

flow of the river above the station- "Second-feet per square mile" 

and "run-off, in inches" are therefore not computed if such 

errors appear probable. The computations are also omitted fof 

stations on streams draining areas in which the annual rainfall is less

than 20 inches. All figures representing " second-rfeet per> aqpiare 

mile" and "run-off in inches" previously published %y^tlie 

should be u§ed wjth caution because of possible in^rent ^SiMiiWlkn 

sources of error. . HI r 1;

Many gfcging stations on streams in .the irrigated sections of the 

United States are located above most of the divenaionsifeotn those 

streams, and the discharge recorded does not show the water supply 

available for further development, as prior appropriations below the 

stations must,first be satisfied. To give; an idea of the amount ofi 

prior appropriations, a paragraph on diversions is.pj?esented in each 

station description. Where values are given thesei-can not be considered exact, hut as being the best information, available.

The table of monthly discharge gives 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, however, that 

the observations in each succeeding year may be expected to throw 

new light on data previously published.

PUBLICATIONS.

Investigation of water resources by the United States Geological 

Survey has consisted in large part of measurements 6f the volume of 

flow of streams and studie's of the conditions affecting that flow, but 

It has comprised also investigation of such closely allied subjects as 

irrigation, water storage, water powers, ground waters, and quality of 

"waters. Most of the results of these investigations -have beeti published in the series of water-supply papers, but some have appeared in 

the monographs, bulletins, professional papers, and annual reports.

The results of stream-flow measurements are now published annually in 12 parts, each part covering an area whose boundaries 

coincide with natural drainage features as indicated below:

The records at. the most of the stations discussed in these reports 

extend over a series of years, and miscellaneous measurements at 

maay :p0ints 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-Supply Paper 119. \

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

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

reports covering the. years durmg which the station was maintained.

LOCATION. A short distance below power house of St. Croix Paper Co. at 

Grand Falls, Baileyville Township, 3J miles east of Baileyville station of 

Maine Central Railroad, Washington County.

DRAINAGE AREA. 1,320 square miles.

RECORDS AVAILABLE. November 25, 1919, io September 30, 1921.

 fAGE.f--Friea water-stage recorder on right bank,referenced,to gage datum by

1 a hook gage inside well; an inclined staff is used for auxiliary readings. 

Recorder inspected by employee of the St. Croix Paper Co.

DISCHARGE MEASUREMENTS. Made from cable 300 feet belo;w gage.

CHANNEL AND CONTROL.' Bed covered with gravel and boulder's; control for 

low and medium stages formed by series of riffles near gage; control for high 

stiiges not clearly defined.

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

recorder, 5.61 feet at 8 p. m. March 29 (dischargej 7,360 second-feet); minimum stage recorded, 1.35 feet at 6 a. m. September 5 (discharge from 

extension of rating curve, 325 second-feet). ....'... 

.! 1919-4921: Maximum stage recorded,; 8.74 feet at noon April 15, 1920 

(discharge from extension of rating curve, 13,900 second-feet); minimum 

stage recorded, that of September 5, 1921. (

ICE. &iver *remains open throughout wmter; stage-discharge relation profe^ 

ably not affected by i^se or by logs; 'r

REGULATION. About 30 billion cubic feet of storage has been developed in 

lakes and ponds above the station. Variations in use of water at power 

' plant a short distance above gage cause some fluctuations in stage.

AccuRAeY.-7-Stage-discharge relation apparently permanent. Rating curve 

fairly well \deflned between 1,000 and 10,000 second-feet. Operation of 

water-stage recorder satisfactory except for short periods as indicated in 

footnote to da.ily'-discharge table. Daily discharge, October 1 to March 

31, ascertained by application of rating table to mean daily gage* height as 

determined by inspection of recorder sheets; April 1 to September 3Q, by 

use of discharge integrator. Records good.

200 feet below a storage dam arid 4 miles above Machias.

DRAINAGE AREA. 465 square miles (measured on State assessor's-map). ; 

AVAILABLE. October 17, 1903, to September,30^ 192L ;« 

Chain installed on the wooden highway bridge Ojtobei1 M), 1911; prf$r

DISCHARGE MEASUREMENTS. Made from, railroad bridge or by wading.

CHANNEL AND CONTROL. Bed sandy, with gravel and alluvial deposits; practically 

permanent. '-;-;

EXTREMES OF DISCHARGE. Maximuna stage recorded during year, 8.7 feet at 

3.45 p. m. December 16 (discharge, 4,470 second-feet); minimum stage 

: recorded, 2.9 feet August1 4 and September, 7-10 (discharge estimated-40 

second-feet; stage-discharge relation affected by logs). "

1903-1921: Maximum stage recorded, 14.7 feet September 30, 190% 

(discharge from extension of rating curve, 11,100 second-feet); minimum;^.' 

stage recorded, 2.5 feet October 6, 1906 (discharge from extension of rating 

curve, 10 second-feet).

ICE. River usually remains open at gage, but ice farther downstream affeete 

the stage-discharge relation.

REGULATION. Opening and closing of gates in storage dam immediately above 

station during low stages of the river cause considerable fluctuation; some 

log driving every year and jams of short duration occasionally occur.

ACCURACY. Two rating curves used during year; curve used before March 4 

being well defined above 100 second-feet, curve used subsequent tp March 4 

fairly well defined above 100 second-feet. Gage read to half-tenths once 

daily. Daily discharge ascertained by applying rating table to mean daily 

gage height with corrections for effect of ice and for log jams. Records fair.

PENOBSCOT RIVER BASIN. 

WEST BRANCH OF PENOBSCOT RIVER AT MILLINOCKET, MAINE.

LOCATION. At Quakish Lake dam and Millinocket mill of Great Northern Paper 

Co., at Millinocket, Penobscot County.

DRAINAGE ABEA. 1,910 square miles (measured on map compiled by Maine 

Water Power Commission).

BECQRDS AVAILABLE. January 11, 1901, to September 30, 1921.

GAGES. Water-stage recorder at Quakish Lake dam and gages in forebay and 

tailrace at mill.

CHANNEL AND CONTROL. Crest of concrete dam.

DISCHABGE. Flow computed by considering flow over the dam, the flow through 

the wheels, and the water used through the log sluices and filters. The 

wheels were rated at Holyoke, Mass., before being placed in position and , were tested later by numerous tube-float and current-meter measurements; 

Ratings for four new wheels installed in 1917 are based on acceptance test 

on one unit after installation; the discharge at various gate openings being 

measured by the use of pitot tubes. When the flow of the river is less than 

3,000 second-feet, all the water generally flows through the wheels of the mill*

ICE. Determination of discharge not seriously affected by ice," Ferguson Pond, 

just above entrance to canal, eliminates effect from anchor- ice.

REGULATION. Dams at outlet of North Twin and Ripogenus lakes store water 

on a surface of about 73 square miles, with a capacity of about 41.5 billion 

cubic feet. Except for a short time during the spring, run-off Is regulated

.'''* by storage. Records corrected for storage., ; , i

COOPERATION. Records furnished by engineers of Great Northern Paper Co.

WEST BRANCH OF PEKOBSOOT RIVER WEAR MED WAY, HAIBTE.

LOCATION. Just above Nichatou Rapids, half a mile above mouth of East 

Branch of Penobscot River and town of Medway, Penobscot County, and 2 

miles below East Millinocket.

DRAINAGE AREA. 2,120 square miles (measured on map compiled .by Main« 

Water Power Commission).

RECORDS AVAILABLE. February 20, 1916> to September 30, 1921.

GAGES. Gurley 7-day watersstage recorder on left bank; inspected by Scott 

Nadeau.

DISCHARGE MEASUREMENTS. Made from cables

CHANNEL AND CONTROL. Bed fairly smooth at measuring section; covered 

with rocks and boulders above and below gage. Channel divides a few 

hundred feet below gage, but practically entire flow passes to left of Nichatou 

Island. Control formed by Nichatou Island and head of Nichatou Rapids; 

'somewhat shifting. n ' ' 

EXTREMES oi1 DISCHARGE. Maximum stage during year from water^sftage 

recorder, 7.21 feet at 6 p. m. April 29 (discharge from extension of rating 

curve, 11,900 second-feet); minimum discharge, by current-meter measurement, 1,060 second-feet, 8 to 9 a. m. July 10.

1916-1921: Maximum stage recorded, 9.88 feet at 1 p. m. June 18, 1917 

(discharge from extension of rating curve, 20,000 second-feet); minimum 

stage recorded, 1.45 feet at 9.45 a. m. January 7, 1917 (discharge from 

extension of rating curve, 585 second-feet). . , .. >

ICE. Ice forms along both banks, but the main channel remains open; stftgfdischarge relation not seriously affected.

REGULATION. Flow at ordinary stages completely regulated by dams iandi 

storage reservoirs above station. . j

ACCURACY. Stage-discharge relation practically permanent during year. Rating 

curve well defined between 1,000 and SyOQO second-feet. Daily discharge 

ascertained, by application of rating table to mean daily gage height determined by inspection of recorder sheets, except for days of large fluctuations 

in stage when the mean of 12 two-hour periods was used. Records good.

GAGES.-^-Charn and ftaff gages on left ban]k; froia October 1, 1915, to September 30, 1917, chain and staff gages on right bank half a mile below highway 

bridge; read by F. A. Lord.

DISCHABGE MEASUREMENTS. Made from cable near gage. ! ! - - ^

CHANNEL AND CONTBOL. Channel rough and somewhat irregular; control'about 

100 feet below gage, subject to shift owing to collection of logs and debris 

from pulp mill.

EXTREMES OF DISCHARGE. Maximum opem-water stage recorded during year, 

3.7 feet at 9 a.-in. April 24 (discharge; 1,960 second-feet); a stage of 4.7 

feet was recorded January 20, but the stage-discharge relation was affected 

by iee at the time; minimum discharge estimated at 5 second-feet several 

times in July and September, when gates at dam were closed.

1916-1921: Maximum stage recorded, 4.8 feet April 19, 2$, and 21, 1920 

(discharge*, 3,390 second-feet); minimum discharge same as in 1921.

ICE. Stage-discharge relation usually affected by ice from December to April.

RBGULATfoN. Distribution of flow somewhat affected ;by use of storage reservoirs above station. -A small dam and mill 400 feet above gage cause diurnal fluctuations in stage when mill is in operation.

ACCTJBACY. Stage-discharge relation seriously affected by logs and de*bris from 

pulp'mill and by -ice during winter. Gage read to quarter-tenths once daily. 

Rating curve well defined below 2,600 second-feet. Daily discharge ascertained by applying rating table to gage height, with corrections for effect 

of iee, log jams, and debris. Records poor.

RECORDS AVAILABLE. April 1, 1895, to September 30, 1921. t ( ,

GAGE. Staff at end of boat landing j two datums have been used at 

the first (or original datum) is 1,011.198 feet above mean gea^ level 

proximately 10 feet below sills of outlet gates; gage is readl to this 

the second, to which all gage readings .published to and including 19J1 ,1-ik 

been referred, is '10 feet higher; that is, the zero is at the sill of the gates; 

as it is believed that low water, may go jbelow the sill of the gates (201:9 j of 

second datum), gage heights since 1912 are published as read, ih^^^to 

original datum. ( , ;

REGULATION. The lake is regulated to a capacity of 23^733 mplion puijic, 

The dam at the east outlet is controlled by 39 gafesb tl^e ^Ul^ Of^jttif 

being .at elevation varying from 8.0 feet to 11.4 feet. « At extreme Ipw, stages 

the flow from the lake is" controlled not by the gates but b^ a ba^. above" the 

dam at an approximate gage height of 9 feet. The records, $^w( flj^ fluctuations in the level of the lak*e and are used in the stucBes of regul^tiqn of the 

lake and in computing the natural flow of Kennebec River a.$ Tt

SURFACE WATER SUPPLY, 1921, PART I.

, KENNEBEC RIVER AT THE FORKS, MAINE.

LOCATION. Half a mile above highway bridge and 1 mile above mouth of 

Dead River at the Forks, Somerset County.

DRAINAGE AREA. 1,570 square miles.

RECORDS AVAILABLE. September 28, 1901, to September 30, 1921.

GAGES. Gurley 7-day recorder on right bank half a mile above highway bridge; 

chain on bridge and water-stage recorder on left abutment used prior to 

October 18, 1919. Recorder inspected by S. C. Durgin.

DISCHARGE MEASUREMENTS. Made from bridge.

CHANNEL AND CONTROL. Channel at bridge is subject to slight changes. Control for new location is well defined by riffles a short distance below gage; 

at old location stage-discharge relation was occasionally affected by backwater from Dead River.

EXTREMES OP DISCHARGE. Maximum stage during year from water-stage 

recorder, 6.36 feet at 7 p. m. April 18 (discharge, 9,440 second-feet) ; minimum stage from water-stage recorder, 1.92 feet at 8 p. m. August 2 (discharge, 532 second-feet).

1901-1921: Maximum stage recorded, 10.1 feet by water-stage recorder 

from 4 to 12 p. m. June 18, 1917 (discharge from extension of rating curve 

23,700 second-feet) ; minimum stage recorded, 0.3 foot at 7 a. m. October 

27, 1911 (discharge, 215 second-feet).

ICE. Stage-discharge relation seriously affected by ice for several months.

REGULATION. Flow regulated by storage in Moosehead Lake. During May, 

June, July, and August the operation of Indian Pond for log driving causes 

a large diurnal fluctuation. Records of monthly dispharge have been 

corrected for storage by adding or subtracting a discharge corresponding 

to the amount of water stored in or released from Moosehead Lake.

ACCURACY. Stage-discharge relation at present location apparently permanent 

except when affected by ice. Rating curve well defined between 500 and 

12,500 second-feet. Operation of water-stage recorder satisfactory, except 

for short periods shown in footnote to daily-discharge table. Daily discharge October 1 to March 31 ascertained by application of rating table 

to mean gage height determined by inspection of recorder sheets, with 

corrections for effect of ice during winter; daily discharge April 1 to September 30 ascertained by use of discharge integrator. Records good.

ANDROSCOGGIN RIVER BASIN. 

ANDROSCOGOIH RIVER AT 1RROL DAM, W. H.

LOCATION. At Errol dam, 1 mile above Errol, Coos County.

DRAINAGE AREA. 1,095 square miles.

RECORDS AVAILABLE. January 1, 1905, to September 30, 1921.

GAGE. Movable rod gage; readings taken daily from sill of deep gate No. 6; 

elevation of zero of gage or sill of gate, 1,231.3 feet above mean sea level.

DISCHARGE. Computed from discharge through 14 gates in the dam by means 

of coefficients determined from a few discharge measurements.2

leas. Stage-discharge relation little affected by ice.

REGULATION. Errol dam regulates the storage of Umbagog Lake, the lower of 

the Rangeley series of lakes, comprising the principal storage of Androscoggin River and amounting to nearly 20 billion cubic feet, and also a developed storage site on Magalloway River created by the Aziscohos dam, 

which amounts to about 9.6 billion cubic feet, thus making the total storage 

about 29.6 billion cubic feet. Errol dam is about 5 miles* below outlet of 

Umbagog Lake and about 3.5 miles below mouth of Magalloway River, thus 

making this stream one of the feeders of Umbagog Lake. Records not 

corrected for storage.

COOPERATION. Records obtained and computations of daily discharge made 

undef direction of Walter'H. Sawyer, agent for Union Water Power Co.,, 

Lewiston, Maine.

PRESUMPSCOT RIVER BASIN.

PEESTJMPSCOT SIVEH. AT OUTLET OF SEBAGO LAKE, MAINE,

LOCATION. At outlet dam at Sebago Lake and hydroelectric plant at Eel Weir 

Falls, 1 mile below lake outlet.

DRAINAGE ABBA. 436 square miles.

RECORDS AVAILABLE. January 1, 1887, to September 30, 1921.

GAGES. On bulkhead of gatehouse at outlet dam, and in forebay and tailrace 

of power plant.

DISCHARGE. Prior to March, 1904, discharge was determined from records of 

opening of gates in dam; since March, i904, flow from lake has been recorded 

by three Alien meters, one on each of three pairs of 30-inch Hercules wheels; 

wheels and recording meters cheeked by current-meter measurements, 

brake tests of wheels, arid;electrical readings of the generator output. Water 

wasted at regulating gates is measured from records of gate openings afed 

coefficients determined from current-meter measurements. Water taken

NOTE. The monthly discharge does not represent the natural flow from the basin because of artiflcia 

storage. The yearly discharge and run-off probably represent more nearly the natural flew, because comparatively little stored water is held over from year to year.

SAGO RIVER AT CORNISH, MAINE.

i-At highway bridge at-Cornish, York County, half a mile below 

mouth of Ossipee River.

DRAINAGE AREA. 1,300 square miles. -..

RECORDS AVAILABLE. June 4, 1946, to September 30, 1921. 

{ GAGES. Friez water-stage recorder on ^eft bank about 300 feet above highway 

bridge, installed October 30, 1919; recorder referenced to gage datum by 

hook gage inside of well; chain on highway bridge used from June 4, .1916, £o 

October 29, 1919. Datum, of ,well gage is at a different elevation" than that 

of chain gage; at low water the well gage reads L17 feet higher than chain 

gage. Recorder inspected by A. H. Guimont.

DISCHARGE MEASUREMENTS. Made from bridge. , - ' :

ipHANNEi* Atfj> CONTROL. 4Bed covered withis&nd arid botilders; channel brokejn 

by one pier at bridge.

EXTREMES QF DISCHARGE'. ^-Maximum stage during year from water-stagje 

recorded, 9.5l feet at &'"a. m. March 28 (discharge, 12,^00 second-feet) J 

minimum stage during year recorded by-chaia,gage, 0.15 foot at 6 a. m. 

September 3 (discharge from extension of rating curve, 100 second-feet).

1916^-1921: Maximuj^ stage recorded, 9.4 feet by chain f age at 6.30 a. to. 

June 18, 1917 (discharge from extension of rating curve, 17,400 second-feetj; 

minimum open-water stage recorded, that of September 3,1921.

ICE. Ice forms to a cbnsi(|erabl§ thickness; stage-discharge relation seriously 

affected duritig most winters., t '';

REGULATION.- Distribution ; df flow somewhat affected by power development 

at Great Falls 3J^ miles above the gage.

ACCURACY. Stage-discharge relation shifts slightly at infrequent intervals; 

present rating curve well defined between 600 and 13^000' second*feet. 

Operation of water-stage recorder satisfactory, except for short periods as 

indicated in footno'tJe ^<Ji|aiiy-dischatge taple. ' Daity discharge ascertained 

by applying rating table to mean daUy gage height determined by inspection of recorder sheetir;'for days When fl&totuation was large, the mean of 

12 bi-hourly gage heights was used, with corrections for effect of ice during 

winter. Records good. ' :i' ''

OSSIPEE RIVER AT CORNISH, MAINE.

-IxjCAtioN. At highway bridge itf Cornish, York County, miles above confluence with Saco River.

'DRAINAGE AREA. 455 square miles (measured on map compiled by Maine 

Water Power Commission).

RECORDS AVAILABLE. July 5, 1916, to September 30, 1921.

GAGE. Chain attached to bridge; read by O, W. Adams: '

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL; Channel covered with sand and gravel; may shift 

slightly; broken by one pier at bridge.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.0 feet at 

8 a. m. December 15 (discharge, 4,160 ;gecond-f eet) ; minimum stage rer 

corded, 0.20 foot at 6 p.! pa. July 3 (discharge from extension of rating curve, 

76 second-feet).

1916-1921: Maximum stage recorded, 7.25 feet June 18, 1917 (discharge 

from extension of rating eurve, 6,480 second-feet); minimum open-water

; stage recorded, that of July 3; 1921.

ICE. Ice forms ta considerable thickness and stage-discharge relation is seriously 

affected during most winters.

REGULATION. Flow regulated by dam at outlet of Great Ossipee Lake. Power 

developments, at Kezar Falls, 5 miles above the gage, may have some effect 

on distribution of flow.

ACCURACY. Stage-discharge relation shifts occasionally at times of high water. 

Two rating curves used during the year; curve used prior to March 13 well 

defined between 400 and 5,000 second-feet; curve used subsequent to 

March 13 well defined between 200 and 5,000 second-feet. Gage read to 

hundredths twice a day. Daily discharge ascertained by applying rating 

table to mean daily gage height with corrections for ice effect. Records good.

MEBRIMACK RIVER BASIN.

PEHIGEWASSET RIVEB. AT PLYMOUTH, N. H.

LOCATION. At two-span highway bridge in Plymouth, Grafton County, threefourths of a mile below mouth of Bakers River.

DRAINAGE AREA. 615 square miles.

R&CORDS AVAILABLE. Jjaivuary 1, 1886, to September ,30, JJ921.

GAGES. Vertical staff gage in thtee sections; two lower sections about 40 feet 

above the bridge; upper section on bridge abutment; pead by, A- F- Morse.

IJISCHA^GE MEASTIREMENT^. Made from" upstream Bide 0f bridge at ordinary 

and high stages^ At extremely low stages measui«emeftts made by wading.

CHANNEL AND CONTROL. Right channel is rocky and practically permanent; 

left channel cpvered with fin$'gravel which shifts occasionally. Control, 

section for low stages is gravel, bed of river and has shifted slightly at various 

times. At high stages banks are overflowed below,the bridge, and the control is somewhat indefinite.

EbtTREMEfs OF DISCHARGE. Maximum open-water stage recorded during the

year, 11.5 feet at 2 p. m. October 1 (discharge, 13,500 second~feet); a stage

of 11.6 feet was "observed at 7 a. m. March 10, but the channel was park , tially obstructed by ice at the time; minimum stage recorded, 0.33 foot on

i July 6, 7, and 9 (discharge, 122 second-feet). ,

1903-1921: Maximum opeji-water stage recorded, 15.42 feet at 7 a. m. 

March 28, 1913 (discharge from extension of rating curve, 18,700 secondfeet); a gage height of 18.17 feet was recorded at 4 p. m. February ?5> 

1915, but stage-disch&rge relation was probably affected by ice at the time. 

Minimum discharge'60 second-feet on September 21, 1913, and August 12, 

1919.

I^E. Eiver freezes over, and stage-discharge relation is affected by ice usually 

from December to Marelu

REGULATION. Several small ponds on Bakers River and other tributaries but 

practically no storage regulation. At very low stages the paper mill at 

Livermore Falls is obliged to shut down several times daily and at these 

times the ponding of water affects the distribution of flow at Plymouth.
SURFACE WATEB .SUPPLY, J.9£l,; PART I.

ACCURACY. Stage^difscharge relation for low stages has, ehanged at various,* 

times and several different rating corves have been used, these different 

rating curves all coinciding for stages above 2,000 second-feet, above which 

point the stage-discharge relation is apparently permanent. Rating curves 

well defined below 15,000 second-feet. Gage read twice daily to half 

inches. Daily discharge ascertained by applying rating table to mean 

daily gage height, with corrections for effect of ice during winters. Records 

good.

F DigCfiAEQis.-^Acpurate record is JkepJ ,ofh,thji_fibw over the 

and through the various 'wheels and gates. Tnis flow includes the

water wasted into, the Merrimack from the Nashua, Sudbury, and Cochituate

drainage basins. Estimates of the quantity wasted from these basins is

furnished by the Metropolitan Water and Sewerage Board of Boston, and

subtracted from the quantity measured at Lawrence to obtain the. n0t

flow from the net drainage area of 4,452 square miles. 

DIVERSIONS. Practically the entire flow of the South Branch of Nashua River,

Sudbury River, and Lake Cochituate is diverted for use by the Metropolitan

water district of Boston. 

RJBQUI/ATION. Flow Regulated to some extent by storage in Lake Winnepeaaukee.

The lo;w--water fldw of the stream is affected by operation of various power

DISCHARGE MEASOTBEMBNTS -^-tMade from bridge or by wading. .

CHANNEL AN» CONTROL. Stream bed is covered with boulders and gravel, 

Ccmtrol at low stages is rock ledge about 50 feet below gage and is well 

defined; at high stages control is probably at a storage dajm about 3 miles 

downstream. . . EXTREMES OF DISCHARGE. Maximum open-wa^er stage iiecordfed during year^ 

10,0 feet at 4 p. m. .December 14 (discharge, by extension^of rating curve, 

2,940 secondTfeet); a stage of 11.9 feet was recorded at noon March 10, but

 ".. the channel wm obstructed by ice; minimum stage, recorded, 1.65t feet at

4 p. m. September 5 (discharge, 27^second-feet). s ' ' ' 

r 1917-1921: Maximum discharge recorded that of i December 14,»i^92^» 

minimum stage recorded, 1.48 feet August 23, 1918 (discharge, 19 secondfeet.) . v - '

ICE. River is usually coyered with, ice for several months during winter.

REGULATION. Considerable storage has been developed in Nubanusit Lake 

 and other reservoirs on the main river and tributaries^ Water power is 

used at various places on the river above the station, the first dam above the 

gage is at North Peterboro, 4 miles upstream. Results obtained from use 

of self-registering gage during August and September, 1921, showed, v^ry 

little diurnal fluctuation. "

ACCURACY. Stage-discharge relation practically permanent, .except when 

affected by ice.. Rating curve fairly well defined between 50 and li?00 

second-feet. Gage read twice daily to hundredths, except during winter 

when it Was read once daily. Daily discharge ascertained by applying rating 

table to mean daily gage height, with corrections for effect of ice duritig 

winter. Records fair.

SUNCOOK RIVER AT NORTH CHICHESTER, XT. H.

LOCATION. 100 feet below highway bridge and 500 feet from Chichester depot, 

North Chichester, Merrimack County, 2J^j miles above mouth of Little 

Suncook River.

DBAINAQE ABBA. 157 square miles (measured on topographic maps).
J. May 21, 1918, to September 30> 1930,'aad June 15 t4

September 30, 1921. 

GAGE. Gurley water-stage recorder on left bank, referred to gage datum by a

book gage inside the well; a vertical staff gage is used for auxiliary readings.

Kecorder inspected by M. H. Gamage.

DISCHARGE MEASUREMENTS. Made from bridge or by wading. 

Gfi&NNEi, ANB CONTROL. Stream bed covered with gravel arid other alluvial

deposits^ Low-water control at head of rapids about 150 feet below gage;

at high water the control is probably formed by crest of an old dam near

Epsom. 

»£XTKEMES-OF DISCHAKGE. - Maximum stage June 15 to September 30,1921, front

water-stage recorder, 3.1 feet at 8 a. m. June 30 (discharge, 344 second-feet);

minimum stage from water-stage recorder, 1.05 feet at 8 a. m. August 29

(discharge 7 second-feet)^ : ., * ? vj *- ,

1918-1921: Maximum stage during periods of record, about 9.1 feet 

'.,.. jMarch 27-28, 1920 (discharge from extension of rating curve, 1,840 secofidfeet); minimum stage, that of August 29, 1921.' . 

ICE. River is covered with ice for several months during winter. 

REGULATION. Storage has been developed at seyerW points above Pittsfieldf

The operation of mills at Pittsfield causes a large variation in discharge

during days when the mills are in operation. 

ACCUBAGY. Stage-discharge relation apparently permanent except when

affected by ice. Rating curve well denned between 10 and 800 secondrfeet.

Daily discharge ascertained by discharge integrator. Records good.

SOTTHEGAN RIVER AT MERRIMACK, IT. H.

LOCATION. At head of Atherton Falls, 7 miles below mouth of Beaver Brook and 

1| miles above confluence of Souhegan and Merrimack rivers at Merrimack, Hillsboro County!

DRAINAGE AREA. 168 square miles.

RECORDS AVAILABLE. July 13, 1909, to September 30, 1921.

GAGES. Gurley printing water-stage recorder on left bank about 350 feet above 

falls installed October 15, 1913; vertical staff and chain gages used prior to 

installation of water-stage recorder. Inspected by employee of W. H. 

McElwain Co.

DISCHARGE MEASUREMENTS. Made by wading below the falls at low stages or 

from cable at high stages.

CHANNEL AND CONTROL. The channel opposite the gage is a pool in which velocity is very low. The control of this pool is a rock ledge at the head of 

Atherton Falls and is permanent.

ICE. Ice forms on control for short periods in the winter; probably no effect 

, from ice during winter of 1920-21.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage recorder> ft. 18 feet at 2 p. m. December 15 (discharge from extension of rating 

curve, 4,550 second-feet); minimum stage from water-stage recorder, 2.03 

feet at 7.30 p. m. September 9 (discharge, 25 second-feet).

1909-1921: Maximum stage recorded, 9.6 feet on August 5, 1915 (discharge from extension of rating curve, 4,936 second-feet); minimum stage 

recorded, 1.90 feet at 8 a. m. September 8,1909 (discharge, 15second-feet).

REGULATION. Flow affected by the operation of the mills at .Milford, about 8 

miles above.

ACCURACY. Stage-discharge relation permanent except when affected by ice for 

short periods. Rating curve well defined below 2,000 second-feet. Operation of water-stage recorder satisfactory except for periods noted in footnote 

to daily-discharge table. Daily discharge ascertained by applying rating 

table to mean daily gage height. Records good for periods when water1 - 

stage recorder was in operation.

ACCURACY. Stage-discharge relation apparently permanent except when affected 

by ice. Rating curve well defined between 200 and 3,400 second-feet, and 

fairly well defined between 100 and 200 second-feet. Gage read to hundredths

PAWTUXET RIVER .BASIN. 

PAWTTnOET RIVER A* FISKZVIUUC, R. t

LOCATION. At an unused mill dam in Fiskeville, Providence County.

DRAINAGE AREA. 101.8 square miles.3 , , ,

RECOBDS AVAILABLE. January 1, 1916, to September 30, 192i;

DETEBMINATION OF DISCBEABQE. Discharge determined from records of stage 

obtained by Gurley water-stage recorder. The dam, which is about 140 feet 

long, has been rated by laboratory tests on a full-size model and by currentmeter measurements made at bridge a short distance upstream. Eating 

curve well defined below 1,400 second-feet. ;

REGULATION. Previous to April, 1919, there were four reservoirs in the basin 

with a capacity of 385 million cubic feet; s»ice April, 1919, there have been 

five reservoirs with a total capacity of 441 million cubic feet. Monthly 

discharge has been corrected for gain or loss in amount of water held in storage* 

A few small mill ponds near Fiskeville hold back water Saturday afternoons 

and Sundays, when the stage of the river is low.

DIVBBSIONS. 'The Pawtuxet Valley Water Go. diverts part of the flow from 1.3 

square miles just above Fiskeville, correction for which has been made.

COOPERATION. Data collected and compiled under the direction of Frank K. 

Winsor, chief engineer, <eity of Providence Water Supply Board.,

* Includes a water area of 2.5 square miles and a swamp area of 2 square miles. Prior to filling one of 

the existing reservoirs in April, 1919, the water area was 2.1 square miles.

QTTINNEBATTG RIVER AT JEWETT CITT, CONK.

LOCATION. About 1,000 feet below railroad bridge and 570 feet below outlet of 

canal from Slater mills (mouth of Pachaug River), in Jewett City, town of 

Griswold, New London County.

DRAINAGE AREA. 712 square miles (measured on topographic maps). 

RECORDS AVAILABLE. July 17, 1918, to September 30, 192L ' '..,' 

GAGES. Gurley 7-day water-stage recorder on left bank referenced to gage 

datum by hook gage inside well; an inclined staff is used for auxiliary read- 

' ings. Recorder inspected by A. B. Ambot. ; 

DISCHARGE MEASUBBMENTS. 'Made from cable. , CHANNEL AND CONTROL. Bed composed of gravel and alluvial deposits. Control 

for low stages is fairly well defined riffle a few hundred feet below ^he gage; 

at high stages the control is at head of rapids 2J^ miles below the gage. 

EXTREMES oS* DISCHARGE. ' Maximum- stage during yea? from water-stage 

recorder, 12.1 feet at 2.30 a. m. December 15 (discharge, 6^050 second-feet); 

minimum stage from water-stage recorder, 4.04 feet at 8 p. m. October 25 

(discharge by extension of rating curve, 52 second-feet, water held back by 

dams).

1918-19£l; Maximum stage, about 16.3 feet during high water of Marc'tn 

14-19, 1920 (discharge from extension of rating curve/ 10,800 second-feet),; 

minimum stage from water-stage recorder; 3.88<feet August 23, 1919 (discharge from extension of rating curve, 30 second-feet; water held back by 

', dftms)., ' :.; '[ ; -; -' ^ 

ICE. Probably little if any effect from ice. REGULATION. The flow of Pachaug River, which, drains $9.7 square miles and 

enters Quinnebaug River through the canal 570 feet above the gage, is under 

almost complete regulation. Numerous small reservoirs and power developments on the main river and tributaries above the station also affect the 

distribution of flow. The operation of mills at Jewett City causes a large 

variation in discharge.

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

defined between 200 and 6,000 second-feet. Operation of water-stage recorder

was satisfactory' except fbr September 3-30, wnen n'b records were obtained.

- -Daily discharge ascertained by use of discharge integrator. Records good

from October to August.

LOCATION. -At outlet of S*irst JfJake, 6 miles northeast of Pittsburg, Coos County.

DRAINAGE AJ^JA. ^31.4 sguare miles (from surveys, by ConnecUcut Valley 

Lumber Co.).

RECORDS AVAJLABJJ$. April 1,1917, to September '30,1921:

GAGEs/--Guiiey Tf-day 'watewstage recorder on right bank about one-fourth 

mile below ths :outlat dam, referred to gage datum by hook,-gage inside thja 

well; an inclined staff gage is used for auxiliary readings. Recorder inspected by H.H. Young. ! fl

DISCHARGE MEASUEEMENTS Made from cable; 200 feet above the gage or by

't , widing. , ' ', . : '' ' . ':.

CHANNEL AND CONTROL Bed rough with rock bottom; channel at cable 

> seetaon Jbas bieen improved by removal of! rocks and ledg^u Control for,

'; river gage is rock ledge extending completely across stream; about 3 feet

' ' of fall immediately belowledge. ;

EXTREMES OF DI&CHAIUP:. Maximum stage during year from water-stage

':: recorder:, 4.02 feet at 1.45 a. m. April 9 (discharge from extension of rating 

curve, 1,460 second-feet, water being released from storage); minimumdischarge during year 5 second-feet during several dayis in Novembet 

(gates closed at dam)

1917-1921: Maximum discharge during period, that of April 9, 1921; 

minimum discharge during period, 3 second-feet during several days in 

April, 1917 (gates closed at dam).

ICE. During extremely cold weather, when stage of river is low, ice occasionally 

: forms on rocks at the control for a few hours eaeh day. Gage heights corrected by comparison of recorder graph with records of gate openings at 

dam.

REGULATION. About 4.1 billion cubic feet of storage has been developed in 

 lakes and ponds above the gage; records of monthly discharge have been 

corrected, for effect of storage in First Lake siKce April, 1917, and for effect 

of storage in Second Lake since .October, 1919.

ACCURACY. Stage-discharge relation subject to occasional changes by reason 

of gravel deposits on bank, opposite gage, and temporarily affected at tunes 

by presence of logs. Rating curve well defined below 800 second-feet. 

Operation of water-stage recorder satisfactory throughout the year. Daily 

discharge ascertained by applying rating table to mean daily gage height, 

using weighted mean discharge for days when variations occurred from 

opening and closing gates at dam. Records good. 

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

WHITE RIVER AT WEST HARTFORD, VT.

LOCATION. 500 feet above highway bridge in West Hartford, Wmdsor Cbunty, 

and 7 miles above mouth of river.

DRAINAGE AREA. 687 square miles.

RECORDS AVAILABLE. June 9, 1915, to September 30, 1921. ' GAGE. Inclined staff on left bank; read by F. P. Morse.

DISCHARGE MEASUREMENTS. Made from cable 1,500, feet Taelow gage or by 

wading.

CHANNEL AND CONTROL. Channel wide and of fairly uniform cross-section at 

measuring section; covered with gravel, and small boulders. Control 

formed by rock ledge 100 feet below gage; well defined. 

EXTREMES OP DISCHARGE; Maximum open-water stage recorded during year, 

12.5 feet at 7 a. m. Msirch 10 (discharge from extension of rating curve, 

15,200 second-feet); minimum stage recorded, 2.55 feet at 6 p. m. September 

10 (discharge from extension of rating curve, 82 second-feet).

1915-1921: Maximum stage recorded, 15.0 feet at 6 p. m. March 28, 

1919 (discharge from extension of rating curve, 20,500 second-feet); minimum stage recorded, 2.33 feet at 6 &L m. August 29, 1916, (discharge from 

extension of rating curve, 26 second-feet). The high water of March 27, 

1913, reached a stage of 18.9 feet, as determined from reference point on 

scale platform opposite gage (discharge not determined.)

ICE. River freezes over at gage; control usually remains partly open, although 

ice on rocks and along shore affects stage-discharge relation.

REGULATION. There are several power plants on main stream and tributaries 

above station, the nearest being thftt of the Sharqn Power Co. (Vermont 

Copper Co., lessee) at Sharori; when this plant is in operation it causes 

some diurnal fluctuation in discharge at low stages. The effect of'.power 

plants farther up-stream is practically eliminated by the large > amount of 

pondage at Sharon.

ACCURACY, Stage-discharge relation practically-, permanent,,exejept wfifeii affected 

by ice. Rating curve fairly well denned between 150 and 5,000 second-feet. 

Staff gage read to quarter-tenths twice daily. Daily discharge ascertained 

by applying rating table to mean daily gage height, with corrections for 

effect of ice during winter. Records good.

SECOND BRANCH OF WHITE RIVER AT NORTH RANDOLPH, VT.

LOCATION. Near school house a quarter of a mile below North Randolph, 

Orange County.

DRAINAGE AREA. Approximately 27, square miles. (Estimated from sketch 

map.)

RECORDS AVAILABLE. October 16, 1920, to September 30, 1921.

GAGE.- Inclined staff on right bank; vertical staff on left bank for high stages.

DISCHARGE, MEASUREMENTS. Made by wading or from farm bridge.

CHANNEL AND -CONTROL. Stream bed covered with gravel and alluvial deposits; 

control formed by ledge rock and gravel, probably permanent.

EXTREMES o# DISCHARGE. Maximum stage recorded during period, 4.6 feet 

at 5 p. m. March 21 (discharge from extension of rating curve, 650 secondfeet) ; minimum stage recorded, 0.9 foot at 6.30 a. m. and 5 p. m. September 

11 (discharge from extension of rating curve, 0.8 second-foot).

ICE. Channel seriously obstructed by ice during winter; stage-discharge rela* 

tion,seriously affected.

REGULATION.-^ Operation of sawmill at North Randolph causes large fluctuation 

in discharge at low stages. As the mill has but a small amount of pondage, 

the flow during the morning hours probably corresponds to natural conditions.

ACCURACY. Stage-discharge relation probably permanent, except when affected 

by ice. Rating curve fairly well defined between 5 and 300 second-feet. 

Gage read to half-tenths twice a day. Daily discharge determined by application of rating table to mean daily gage height, except for periods when 

sawmill caused fluctuations in stage the rating table was applied to morning 

gage height only. Records fair.

ASHTTELOT RIVER AT HINSDALE, ST. H.

LOCATION. At lower steel highway bridge in Hinsdale, Cheshire County, a

quarter of a mile below dam of Fisk Paper Co. and 1| miles above mouth

of river.

DRAINAGE AREA. 440 square miles. 

RECORDS AVAILABLE. February 22, 1907, to December 31, 1909, and July 11,

1914, to September 30, 1921.

GAGE. Chain gage on downstream side of bridge; read by Teresa Golden. 

DISCHARGE MEASUREMENTS. Made from highway bridge. 

CHANNEL AND CONTROL. Channel covered with coarse gravel and boulders.

Control is a short distance below the gage; practically permanent. 

EXTREMES OF DISCHARGE. Maximum stage recorded -during year, 7.25 feet,at

4 p. m. March 12 (discharge from extension of rating curve, 4,810 second-'

feet); minimum stage recorded, 2.51 feet at 8 a. m. June.24 (discharge, froni,

extension of rating curve, 54 seconds-feet).

1914-1921: Maximum stage recorded, 9.98 feet March 29, 1920 (discharge

from extension of rating curve, 8,940 second-feet); minimum stage recordedt

2.0 feet at 4 p. m. October 4, 1914 (discharge from extension of rating curve,

10 second-feet). 

ICE. Ice forms below bridge on control, affecting stage-discharge relation for

short periods. 

REGULATION. The mills immediately above station are operated continuously

except Sundays and holidays, but cause little fluctuation in stage. Several

reservoirs and ponds on the river and tributaries have some effect pit the.

distribution of flow. The effect of power regulation was studied by a,'

temporary installation of water-stage recorder during July, and August, iSlfci 

ACCURACY. Stage-discharge relation practically permanent except when affected!

by ice. Rating curve fairly well defined below 4,000 second-feet. Gage

read to. hundredths twice daily. Daily discharge ascertained by applying!

rating table to mean daily gage'height, with corrections for effect of ice

during winter. Records good.
96 SURFACE WATER SUPPLY, 1921, PART I.

The following discharge measurement was made by Lamson and Armstrong: 

Apr. 21, 1921: Gage height, 4.84 feet; discharge, 1,390 second-feet.

CONNECTICUT RIVER BASIN,

MUTNEWAWA BROOK AT HARLBORO, H. H.

LOCATION, In Marlboro, Cheshire Cotmty, 300 feet from Marlboro-Keene town 

line and 1 mile above confluence with East Branch of Ashuelot River.

DRAINAGE AREA. 31.7 square miles.

RECORDS AVAILABLE. July 25, 1919, to September 30, 1921.

GAGE. Gurley 7-day water-stage recorder on left bank, referenced to gage 

datum by a hook gage inside the well; an inclined staff is used for auxiliary 

readings. Recorder inspected by Edwin S. L'heureux and F. V. Perry.

DISCHARGE MEASUREMENTS. Made by wading or from highway bridge 500 feet 

above gage.

CHANNEL AND CONTROL. Channel rough with steep slope; control somewhat 

shifting.

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

recorder, 8.22 feet at 7.30 p. m. March 9 (channel may have been obstructed 

by temporary ice jam, discharge not determined); practically no discharge 

at various times when water was held back by dams.

1919-1921: Maximum stage recorded, 8.3 feet March 14, 1920 (channel 

probably obstructed by ice, discharge not determined); practically no discharge at various times when water was held back by dams.

ICE. Ice forms on rocks and at the control; channel fills with slush ice, and 

occasional ice gorges occur; stage-discharge relation seriously affected.

REGULATION. Flow at ordinary stages is under complete regulation by power 

plants in Marlboro; several small reservoirs also affect the distribution of 

flow.

ACCURACY. -Stage discharge-relation .subject to occasional changes. Rating 

curves fairly well defined between 8 and 340 second-feet. Operation of waterstage recorder satisfactory, except for short periods mentioned in footnote 

to daily-discharge table. Daily discharge ascertained by applying rating 

table to mean daily gage height, with corrections for ice during winter. 

Records fair.

CONNECTICUT EIVEE BASIN. 99

PRATT BROOK AT CHESHAM, N. H. 

y

LOCATION. At ruins of old dam just below highway bridge on Marlboro-Chesham 

road, a quarter of a mile above confluence with Minnewawa Brook and half 

a mile from Chesham railroad station in Harrisville Township, Cheshire 

County.

DKAINAGE ABE A. 11.2 square miles (measured on topographic map).

RECORDS AVAILABLE. July 8, 1919, to September 30, 1921, when station was 

discontinued.

GAGE. Inclined staff near right end of old dam; read by E. G. Russell.

DISCHARGE MEASUREMENTS. -Made by wading or from highway bridge.

CHANNEL AND CONTROL. Formed by mud-sill of old dam and by ledge rock.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.8 feet at 

7.30 a. m. March 10 (discharge from extension of rating curve, 900 second 

feet); minimum stage recorded during year, 1,09 feet several times during 

September (discharge from extension of rating curve, 0.4 second-foot). 

1919-1921: Maximum and minimum stages same as in 1921.

ICE. Ice forms on rpcks below the gage but is cleared away by observer so that 

stage-discharge relation is not seriously affected1.

REGULATION. Flow regulated by storage in Howe reservoir; gates changed at 

infrequent intervals.

ACCURACY. Stage-discharge relation practically permanent. Rating curve 

well defined by discharge measurements between 2 and 20 second-feet and 

at 154 second-feet; curve between 20 and 150 second-feet and above 160 

second-feet based on logarithmic extension. Gage read to hundredths 

twice daily except from December 20 to March 6, when it was read once a 

day. Daily discharge ascertained by applying rating table to mean daily 

gage height. Records good.

CONNECTICUT, KIVEE BASIN. 101

SOUTH BRANCH OF ASHTTELOT RIVER AT WEBB, NEAR MARLBORO, N. H.

LOCATION. At highway bridge on State road between Iteene and Troy, a quarter 

of a mile from Webb railroad station, Marlboro, Cheshire County.

DRAINAGE AREA. 36.6 square miles (measured on topographic map.)

RECORDS AVAILABLE. November 16,1920, to September 30,1921.

GAGES. Friez water-stage recorder on right bank, downstream side of bridge, 

referenced to gage datum by hook gage inside the well; an inclined staff Is 

used for auxiliary .readings. Recorder inspected by O. J. Bemis.

DISCHARGES MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Large pool opposite gage, water swift above and 

below. Control is formed by boulders 50 feet below gage; probably permanent.

EXTREMES OF DISCHARGE. Maximum open-water stage during period from 

water-stage recorder, 5.0 feet at 5 p. m. December 5 (discharge from extension of rating curve, 780 second-feet), a stage of 5.8 feet was recorded at 

10 p. m. March 9, but the channel was obstructed by ice at the time; minimum stage from water-stage recorder, 1.00 foot on several days in September 

(discharge from extension of rating curve, 3 second-feet).

ICE. Channel obstructed by ice during winter.

REGULATION. Distribution of flow affected by operation of mills at Troy, 

4 miles upstream; several- small storage ponds on main stream and tributaries above gage.

ACCURACY. Stage-discharge relation probably permanent except when affected 

by ice. Rating curve fairly well denned between 8 and 400 second-feet. 

Operation of water-stage recorder .generally satisfactory except for periods 

indicated in footnote to daily-discharge table. Daily discharge ascertained 

by application of rating table to mean daily gage height, as determined from 

inspection of recorder sheets, with correction for effect of ice during winter. 

Records fair.

CONNECTICUT RIVER BASIN. 103

MILLERS RIVER NEAR WINCHENDON, MASS.

LOCATION. At steel highway bridge known SB Nolan-s Bridge, half a mile below 

mouth of Sip Pond Brook and 2 miles west of Winchendon, Worcester 

County.

DRAINAGE AHEA. 80.0 square miles.

RECORDS AVAILABLE. June 5, 1916, to September 30, 1921,

GAGES. Water-stage recorder on right bank below highway bridge installed 

July 4, 1917; referenced to gage datum by hook gage inside well. Staff on 

bridge abutment used for auxiliary readings. Recorder inspected by H. D. 

Sawyer.

DISCHARGE MEASUREMENTS. ;Made from highway bridge or by wading.

CHANNEL AND CONTROL. Channel covered with gravel and alluvial deposits 

Control for low and medium stages is gravel bar about 80 feet below gage.

EXTREMES OP DISCHARGE. Maximum stage during year, from water-stage recorder, 7.85 feet at 11 a. m. May 1 (discharge from extension of rating curve 

1,040 second-feet); minimum stage from water-stage recorder, 2.94 feet at 

7 a. m. September 19 (discharge, 15 second-feet).

1916-1921: Maximum stage recorded, 8.3 feet at noon May 23, 1919 

(discharge from extension of rating curve, 1,160 second-feet); minimum stage 

recorded, 2.02 feet at 5 a. m. September 20, 1918 (discharge, practically 

zero; water held back by dams).

ICE. Ice cover usually forms during winter and owing to large diurnal fluctuation caused by operation of power plants near Winchendon, water frequently 

overflows the ice. -,

REGULATION. The distribution of flow is affected by operation of power plants 

at and below Winchendon and by storage in Lake Monomonac and other 

reservoirs.

ACCURACY. Stage-discharge relation apparently permanent during year. Rating curve fairly well defined. Operation of water-stage recorder was satisfactory throughout year. Daily discharge ascertained by applying rating 

table to mean daily gage height as determined from recorder sheets from 

October 1 to April 15 and August 27 to September 30, with corrections for 

effect of ice during winter; discharge integrator used for period April 16 to 

August 26. Records good.

CONNECTICUT RIVER BASIN.

MILLERS RIVER AT BUYING, MASS.

105

LOCATION. A quarter of a mile below dam at Erving, Franklin County, 8 miles 

above confluence of Millers River with Connecticut River and below all 

important tributaries.

DRAINAGE AREA. 372 square miles.

RECORDS AVAILABLE. August 1, 1914, to September 30, 1921.

GAGE. Stevens water-stage recorder on right bank near downstream end of 

old chair factory; hook gage in well; vertical staff attached to downstream 

end of factory wall is used for auxiliary readings. Water-stage recorder 

inspected by Napoleon Lemire.

DISCHARGE MEASUREMENTS. Made from cable near gage or by wading.

CHANNEL AND CONTROL. Channel covered with coarse gravel and boulders; 

control section is a short distance below gage; practically permanent.

EXTREMES or DISCHARGE. Maximum stage during year from water-stage 

recorder, 5.54 feet at 1.45 p. m. May 2 (discharge, 5,300 second-feet); 

minimum stage from water-stage recorder, 1.03 feet at 3 p. m. September 19 

(discharge, 12 second-feet).

1914-1921: Maximum open-water stage recorded, 5.74 feet at 10 a. m. 

March 28, 1920 (discharge, 5,800 second-feet); a stage of 5.97 feet was 

recorded at 8.30 a. m. February 27, 1918, but stage-discharge relation was 

affected by ice; minimum discharge, practically zero at times during 1915 

and 1916, when water was held back by dams above gage.

ICE. River freezes over below the gage at various times; ice considerably 

broken by rising and falling stages due to power operations; stage-discharge 

relation is seriously affected.

REGULATION. Distribution of flow affected by operation of various power 

plants and storage reservoirs above station.

ACCURACY. Stage-discharge relation practically permanent except when affected 

by ice. Rating curve well defined below 4,000 second-feet. Operation of 

water-stage recorder was satisfactory except for short period as indicated 

in footnote to daily discharge table. Daily discharge ascertained by use 

of discharge integrator, with corrections for effect of ice during winter. 

Records good.

GG2OTECTICUT RIVER BASEST.

 . SIP POND BKOOK NEAR WINCHENDON, MASS.

LOCATION. 600 feet above highway bridge, a quarter of a mile below Massachusetts-New Hampshire State line, If miles below outlet of Sip Pond, and 

3 miles northwest of Winchendon, Worcester County.

DKAINAQE AREA. 18.8 square miles.

KECORDS AVAILABLE. May 29, 1916, to September 30, 1921.

GAQES. Gurley graph water-stage recorder on left bank 500 feet above highway bridge, with hook gage inside well; a vertical staff is used for auxiliary 

readings. Prior to June 26, 1917, an inclined staff on right bank 50 feet 

above highway bridge was used. Recorder inspected by Mary N. Greenall.

DISCHARGE MEASUREMENTS. Made from footbridge, 15 feet below vertical 

staff gage, or by wading.

'CHANNEL AND CONTROL. Channel rough with boulders. Control clearly 

defined.

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

recorder, 8.88 feet at noon December 6 (discharge, 259 second-feet); minimum stage from water-stage recorder, 4.95 feet at noon, September 11 

(discharge, 1.2 second-feet).

1916-1921: Maximum stage recorded, 9.34 feet at 1 p. m. May 23, 1919 

(discharge from extension of rating curve, 339 second-feet); minimum 

discharge, 1.1 second-feet, at 6 p. m. August 16, 1919.

ICE. Channel usually remains open during winter; ice occasionally forms in 

float well, interfering with operation of water-stage recorder.

KEGULATION. The distribution of flow is considerably affected by operation 

of mills at State Line, N. H., and by storage in Pearly and Srp Ponds.

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

defined below 250 second-feet. Operation of water-stage recorder fairly 

satisfactory, except during winter when it was affected by ice in flpat well. 

Daily discharge ascertained by applying rating table to mean daily gage 

height with corrections for effect of ice during winter. Records good 

during open-water periods, and fair during winter.

section and gravel bottom. Control is formed by the foundation of an old

dam 30 feet below gage and is practically permanent. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.9 feet at

8 a. m. May 1 (discharge from extension of rating curve, 288 second-feet);

minimum stage recorded, 2.02 feet at 8 a. m. August 21 (discharge, 0,4

second-foot).

Maximum stage during the periods May 25, 1916, to September 30, 1917,

and July 18, 1918, to September 30, 1921, estimated as 6.5 feet (water over

top of gage) at 7 a. m. March 28, 1919 (discharge from extension of rating

curve, 700 second-feet); minimum stage recorded during periods, that of

August 21, 1921. 

ICE. Brook freezes over at gage, but usually remains open at control; stage-?

discharge relation seldom affected by ice. 

REGULATION. Flow not appreciably affected by regulation. 

ACCURACY. Stage-discharge relation has changed at infrequent intervals.

Rating curves fairly well defined below 200 second-feet. Gage read to

hundredths twice daily. Daily discharge ascertained by applying rating

table to mean daily gage heights. Records good.

DEEBFIELD BIVER AT CHARLEMOUT, MASS.

LOCATION. One mile below village of Charlemont, Franklin County.

DBAINAGE ABEA. 882 square miles.

RECOBDS AVAILABLE. June 19, 1913, to September 30, 1921.

GAGES. Friez water-stage recorder on left bank, referenced to gage datum by a 

, hook gage inside the well; an inclined staff gage is used for auxiliary readings. 

Recorder inspected by C. H. Haskins and E, F. Spear.

DISCHARGE MEASUREMENTS. Made from cable or by wading*

CHANNEL AND CONTROL. Channel covered with coarse gravel and boulders; 

fairly uniform section; control practically permanent.

EXTBEMKS OF DISCHABGE. Maximum stage during year from water-stage recorder, 13.35 feet at 7 p. m. March 9 (discharge from extension of rating 

curve, 32,400 second-feet); minimum stage during year from water-stage 

recorder, 0.70 foot at 11 p. m. June 17 (practically no discharge, water held 

back by dams at power stations above the gage).

1913-1921: Maximum stage recorded, 15.7 feet on July 8, 1915 (discharge 

from extension of rating curve, 45,000 second-feet); minimum stage recorded, 

that of June 17, 1921,

ICE. River usually frozen over during greater part of whiter; ice jams occasionally form below gage causing several feet of backwater.

REGULATION. Flow during low and medium stages largely regulated by a storage 

reservoir at Somerset, Vt. Several power plants above the station cause 

diurnal fluctuation. Monthly discharge corrected for storage at Somerset.

ACCUBACT. Stage-discharge relation practically permanent, except when affected by ice. Rating curve well defined below 10,000 second-feet. Operation of water-stage recorder satisfactory except for short intervals as shown 

in footnote to daily-discharge table. Daily discharge Oct. 1 to Jan. 17, and 

Mar. 27 to June 15, ascertained by discharge integrator; during remainder of 

year by applying rating table to mean daily gage height from recorder sheets 

with corrections for effect of ice during winter. Records good.

CONNECTICUT BIVEE

WARE RIVER AT GIBBS GROSSING, MASS.

LOCATION. Between highway and electric railway bridges at Gibbs Crossing, 

three-quarters of a mile above mouth of Beaver Brook and 3 miles below 

Ware, Hampshire County.

DRAINAGE AREA. 201 square miles.

RECORDS AVAILABLE. August 20, 1912, to September 30, 1921.

GAGES. Gurley 7-day water-stage recorder on right bank referred to gage datum 

by a hook gage inside of well; an inclined?staff gage is used for auxiliary 

readings. Recorder inspected by Marion G. Moore.

DISCHARGE MEASUREMENTS. Made from electric railway bridge* or by wading.

CHANNEL ,AND CONTROL. Channel rough and subject to a growth of aquatic 

vegetation during summer. Control free from weeds and at ordinary 

stages well defined at a section near gage; shifts occasionally; at high stages 

the control is probably at the dam at Thorndike, 4 miles below gage.

EXTREMES OF DISCHARGE. Maximum stageduring year from water-stage recorder,, 

4.90 feet at 11 p. m. May 1 (discharge, 2,200 second-feet); minimum stage 

from water-stage recorder, 1.32 feet at 10 a. m. September 30 (discharge, 21 

second-feet).

1912-1921: Maximum open-water stage recorded, 6.00 feet on March 27, 

1920 (discharge, 2,820 second-feet); minimum stage recorded, 1.20 feet on 

October 26, 1914 (discharge, 5 second-feet).

ICE. River usually freezes over, and the stage-discharge relation is affected by 

ice during most winters.

REGULATION. Flow affected by operation of mills at Ware, which at low stages 

causes a large variation in discharge on days when the mills are in operation, 

and a low discharge on Sundays and holidays.

ACCURACY. Stage-discharge relation apparently permanent throughout year 

except when affected by ice; probably not affected during present year. 

Rating curve well defined below 1,800 second-feet, and fairly well defined 

below 2,700 second-feet. Operation of water-stage recorder was satisfactory 

throughout year. Daily discharge ascertained by use of discharge integrator. Records good.

SWIFT BJVER AT WEST WARE, MASS.

LOCATION. 1,000 feet below old wooden dam opposite West Ware station of 

Boston & Albany Railroad, in Hampshire County, 6 miles downstream from 

Enfield, and 3 miles below confluence of East and We^t branches of Swift 

River.

DRAINAGE AREA. 186 square miles.

RECORDS AVAILABLE. July 15, 1910, to September 30, 1921. .

GAGES. Gurley 7-day water-stage recorder on left bank, referenced to gage 

datum by a hook gage inside of well} an inclined staff is used for auxiliary 

readings. Recorder inspected by H. C. Davis. *

DISCHARGE MEASUREMENTS. Made from cable or by wading.

CHANNEL AND CONTROL. Gravel and alluvial deposits; some aquatic vegetation in channel during summer. Control has shifted slightly at times, the 

greatest change occurring during high water of April 3, 1916, when dam 

above gage was washed out; at high stages the control is probably at the dam 

at Bondsville, 4 miles below gage.

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

recorder, 8.80 feet at 1 a. m. May 2 (discharge^ from extension of rating 

curve, 2,280 second-feet); minimum stage from water-stage recorder, 2.07 

feet at 1 a. m. September 7 (discharge, 89 second-feet).

1910-1921: Maximum discharge recorded, 2,340 second-feet (from extension of rating curve) on September 28, 1920; minimum discharge recorded 

22 second-feet on September 22, 1914.

ICE. River usually freezes over; discharge relation is affected by ice for short 

periods during most winters.

REGULATION. Operation of mills at Enfield 6 miles above station has at times 

affected the distribution of flow at low and medium stages; not seriously 

affected during present year.

ACCURACY. Stage-discharge gelation has changed at infrequent, intervals, 

practically permanent during present year. .Rating curve well defined 

below 1,500 second-feet. Operation of water-stage recorder was satisfactory 

throughout year. Daily discharge ascertained by applying rating table to 

mean daily gage height determined by inspection of gage-height graph, 

with corrections for effect of ice during winter. Records good.

QTTABOAG RIVER AT WEST, BRIMFIELD, MASS.

LOCATION. At two-span highway bridge near West Brimfield station of Boston 

& Albany Railroad in Hampden County, one-third mile above mouth of 

Blodgett MiU Brook.

DRAINAGE ABBA. 150 square miles.

RECORDS AVAILABLE. August 23, 1909, to September 30, 1921.

GAGES. Gurley 7-day water-stage recorder at downstream end of center pier 

of bridge, referenced to gage datum by means of a hook gage inside well; 

a vertical staff on upstream side of right abutment of bridge is used for 

auxiliary readings. Recorder inspected by Mrs. G. G. Alien.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading near 

bridge.

PHANNEL AND CONTROL. Stream bed covered with boulders, gravel, and alluvial deposits; slight shifts in control have occurred at times.

EXTREMES OF DISCHARGE. Maximum open-water stage during year from waterstage recorder, 3.95 feet at 7.30 a. m. May 3 (discharge, 970 second-feet); 

a stage of 4.03 feet occurred at 2 p. m. January 29, but channel obstructed 

by ice; minimum stage from water-stage recorder, 1.78 feet at 5 a. m. September 7 and 7 a. m. September 8 (discharge, from extension of rating 

curve, 10 second-feet).

1909^-1921: Maximum open-water stage recorded, 5.3 feet at noon March 

17, 1920 (discharge, 1,980 second-feet); minimum stage recorded, 1.40 feet 

on September 17 and 18, 1910 discharge, 2.5 second-feet (water held back 

by dams).

ICE. River usually freezes over; stage-discharge relation affected during most 

winters.

REGULATION. Flow affected by operation of power plants at West Warren, 

3 miles above station, which at low stages causes a large variation in discharge 

on days when mills are in operation and a low discharge on Sundays and 

holidays.

ACCURACY. Stagerdischarge relation has changed slightly at times. Rating 

curves used October 1 to February 28 and March 1 to September 30, well 

defined. Operation of water-stage recorder satisfactory throughout year, 

except for short periods as indicated in footnote to daily-discharge table. 

Daily discharge ascertained by applying rating table to mean daily gage 

height as taken from record sheets, with corrections for ice during winter. 

Records good.

WESTFIELD RIVER HEAR WESTFIELD, MASS.

J/OCATION. At Trap Rock Crossing, 3 miles east of Westfield, Hampden County, 

1 mile below mouth of Big Brook, and 2 miles below mouth of Westfield 

Little River.

DRAINAGE AREA. 496 square miles.

RECORDS AVAILABLE. June 27, 1914, to September 30, 1921.

GAGES. Stevens continuous water-stage recorder on right bank, referenced to 

gage datum by means of a hook gage inside well; an inclined staff gage is 

used for auxiliary readings. Recorder inspected by Andrew Kelly.

DISCHARGE MEASUREMENTS. Made from cable or by wading.

CHANNEL AND CONTROL. Bed covered with gravel and alluvial deposits; riffle 

of boulders about 200 feet below gage forms control at low and medium 

stages. At high stages control is probably formed by crest of storage dam at 

Mittineague, 3 miles below station.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage recorder, 15.9 feet at 1.30 a. m. December 15 (discharge from extension of rating 

curve, 15,200 second-feet); minimum stage from water-stage recorder, 3.20 

feet at 4 p. m. September 4 (discharge, 90 second-feet). 

1914-1921: Maximum stage recorded, 17.4 feet on August 4, 1915, and 

May 22, 1919 (discharge from extension 6f rating curve, 17,400 second-feet); 

minimum stage recorded, 3.02 feet on September 24, 1914 (discharge, 46 

second-feet). -

ICE. Stage-discharge relation slightly affected by ice for short periods during 

some winters. !

DIVERSIONS. Water is diverted from Westfield Little River and carried to 

Springfield for municipal use. Monthly discharge corrected for diversion.

REGULATION. There are several power plants above station, but diurnal fluctuation is small; the nearest dam is at Westfield.

ACCURACY. Stage-discharge relation practically permanent; probably not 

affected by ice during winter of 1920-21. Rating curve well defined below 

7,500 second-feet. Operation of water-stage recorder satisfactory except 

for periods shown in footnote to daily-discharge table. Daily discharge 

ascertained by application ol rating table to mean daily gage height, as 

determined from recorder sheets. Records good.

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

August 3, 1921: Gage height, 3.57 feet; discharge, 205 second-feet.

LOCATION. At highway bridge in Goes Heights, Hampshire County, If miles 

above village of Huntington ajid half a mile above confluence of Middle and 

North branches of Westfield River.

DEAINAGE ABBA. 53 square miles.

RECORDS AVAILABLE. July 14, 1910, to September 30, 1921.

GAGES. Water-stage recorder on upstream side of bridge abutment on right 

bank, referenced to gage datum by means of a hook gage inside of well; an 

inclined staff is used for auxiliary readings. Recorder inspected by Doric© 

Cady.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Channel covered with coarse gravel and boulders. 

Control somewhat shifting.

EXTREMES OP DISCHARGE. Maximum stage during year from water-stage recorder, 6.35 feet at 8.15 p. m. March 9 (discharge from extension of rating 

curve, 3,650 second-feet); minimum stage from water-stage recorder, 0.76 

foot August 7 (throughout the 24 hours) (discharge, 14 second-feet).

1910-1921: Maximum open water stage recorded, 7.33 feet on July 8, 

1915 (discharge from extension of rating curve, 4,500 second-feet); minimum 

stage recorded, 0.70 foot on October 26-27, 1914 (discharge, practically 

zero.

ICE. River usually frozen over during greater part of winter; ice jams occa» 

sionally form below gage, causing several feet of backwater.

REGULATION. Flow somewhat affected at times by operation of small powerplant about 2 miles above station. ;.

ACCURACY. -Stage-discharge relation for stages below 40 second-feet changed 

slightly during high water of March, 1921. Rating curves used before and 

after the change well defined below 1,000 second-feet. Operation of water- 

. stage recorder not entirely satisfactory. Daily discharge ascertained by 

applying rating table to mean daily gage height determined by inspection, of 

gage-height graph, except for periods as noted in footnote to daily-discharge 

' tablet Gage'heights corrected for -effect of ice dtuihg winter. Record^. 

good October 1 to December I, January 6 to March 9, and May 28 to September 30; records fair for other periods. .

WESTFIELD LITTLE BIVER NEAR WESTFIELD, MASS. r 1

LOCATION. At diversion dam of Springfield waterworks, in town of Russell, 

Hampden County, 3 miles below confluence of Pebble and Borden Brooks 

and 3 mfies west of Westfield. Originally (July, 1905, to December, 1909) 

a short distance below Borden Brook, near Cobble Mountain.

DRAINAGE ARK A. 43 square miles at original site; 48.5 square miles at present 

site. * : :

RECORDS AVAILABLE. July 13, 1905, to September 30, 1921.

DBTEEMINATION OF DISCHARGE. At the original site below Borden Brook (used 

1905-1909) the discharge was determined by methods commonly employed 

at current-meter gaging stations. From August, 1906, to September, 1907, 

a 30-foot weir was maintained a short distance below the gage.*

Since March 1, 1910, high-water flow determine^ from eonlfintuous record** 

of head on concrete diversion dam (crest length, 155.4 feet), for which' 

coefficients have been deduced from experiment^ at Cornell Universityj! 

low-water flow, less than 163 second-feet, determined from continuous, 

record of head on a 12-foot sharp-crested weir without end contractions, the; 

crest being 2.5§,feet beloW that of the dam. Water Mverte|l to city of,!

! Springfield is measured by a 54«mch Venturf meter,-using continuous record*-

CHANNEL AND CONTROL. Stream bed covered with gravel and deposits of 

manufacturing waste and sediment; control is at well-defined riffle 200 

feet below gage.

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

recorder, 4.34 feet at 7 p. m. December 5 and at 4 a. m. December 15 (discharge, 623 second-feet); practically no discharge at times when water 

was held back by dams.

1919-1921: Maximum stage recorded, 8.1 feet at 5 p. m. March 13, 1920 

(discharge from extension of rating curve, 1,450 seeond-feet); practically no 

discharge at times when water was held back by dams.

ICE. Some ice forms along river banks but not; fa sufficient quantities to affect; 

stage-discharge relation. ! ;

REGULATION. Distribution of flow affected by operation of mills above gage 

and by storage in Shenipsit Lake. j L .

ACCURACY. Stage-discharge relationMs apparently permanent. ,l! Rating curve 

fairly well defined between lObiand 500 second-feet;*extended above 50Q 

second-feet as a tangent. Operation of water-stage recorder was satisfactory throughout year except for period indicated in footnote to dafly-dischafge' 

table. Daily discnarge^asceirtemed by use

HOUSATONIC RIVER AT FALLS VILLAGE, CONN.

LOCATION. Half a mile below power plant of Connecticut Power Co. at Falls Village, Litchfield County, 23 miles north of Gaylordsville. 

DRAINAGE AREA. 644 square miles. 

RECORDS AVAILABLE. July 11, 1912, to September 30, 1921.
HQUSATONIC EIVBB BASIN.

GAGES. Stevens continuous water-stage recorder on left bank, referenced to 

gage datum by hook gage inside well; a vertical staff on river bank 25 feet 

'upstream and chain gage 300 feet upstream are used for-auxiliary readings. 

Recorder inspected by an employee of the Connecticut Power Co.

DISCHAKGE MEASUREMENTS. Made from cable 150 feet above gage or by wading.

CHANNEL AND CONTROL. Channel deep and fairly uniform in cross-section; one 

channel at all stages. Control not clearly defined except at low stages; 

probably permanent.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage recorder, 9.8 feet at 5 p. m. March 11 (discharge, 5,490 second-feet); minimum 

stage from" water-stage recorder, 0.72 foot at midnight September 30 (discharge, 42 second-feet; water held back by dam).

1912-1921: Maximum stage recorded, 13.3 feet on March 29, 1914 (discharge, 8,830 second-feet); zero flow at times owing to storage of water above 

power plant. ;

ICE. Stage-discharge relation affected by ice during some winters.

REGULATION. Low-water flow is completely regulated by power plant at Falls

' Village.

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

defined between 200 and 7,000 second-feet. Operation of water-stage recorder satisfactory except for short periods as shown in footnote to dailydischarge table. Daily discharge ascertained by use of discharge integrator. 

Records good. i . :

The following discharge measurement wasinade by E.'E. R. EJornbacfai 

Feb. 14, 1921: Gage height, 2.38 feet; discharge, 583 seeond-feet. *

MIANUS RIVER BASIN. 

MIAUTTJS RIVER AT NORTH MIAHTJS, CONK.

LOCATION. At Palmer dam, 1 mile north of Mianus, Greenwich Township, and 

2 miles west of Stamford, Fairfield County.

DRAINAGE AREA. 29.9 square miles.

RECORDS AVAILABLE. February 4, 1920, to September 30, 1921.

GAGE. Friez water-stage recorder on right bank about halfway between dam 

and highway bridge; referenced to gage datum by hook gage inside well. 

Recorder inspected by E. N. Sampson.

DISCHARGE MEASUREMENTS. Made at cable section about one-fourth mile above 

gage, and also at highway bridge.

CHANNEL AND CONTROL. The old rm}\ pond extends back to the highway bridge; 

water opposite gage is smooth, with low velocity at ordinary stages. Control is formed by crest of 6-foot sharp-crested weir without end contractions 

built in old canal at right end of dam; water begins to go over crest of dam 

at gage height 1.85 feet; dam has a spillway length of 79.2 feet, with smooth 

rounded crest.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage recorder,. 3,40 feet at 1 a. in. October 1 (discharge from extension of rating 

curve, 675 second-feet); minimum stage from water-stage recorder, 0.25 

feet from 1 to 8 a. m. August 30 (discharge, 1.4 se&md^foot).

1920-1921: Maximum stage recorded, 3.67 feet at 5 p. m. September 

30, 1920 (discharge from extension of rating curve, 810 second-feet); minimum stage recorded, that of August 30,1921.

ICE. Weir remains clear of ice, stage-discharge relation not affected.

REGULATION. Operation of a mill 1 mile above gage causes large fluctuations 

in discharge at ordinary stages.

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

defined below 260 second-feet. Operation of water-stage recorder satisfactory. Daily discharge ascertained by averaging discharge for 12 twohour periods. Records excellent.

No discharge measurements were made during the year.

HUDSON RIVER BASIN.

HUDSON RIVER AT GOOLEY, HEAR INDIAN LAKE, K. Y.

LOCATION*. 1 mile above Gooley, Essex County, 1 mile below mouth of Cedar 

River, 1% miles above mouth of Indian River, and 6 miles northeast of 

Indian Lake village, Hamilton County.

DRAINAGE AREA. 418 square miles (measured.on topographic maps).

RECORDS AVAILABLE. August 30, 1916, to September 30, 1921,

GAGE. Gurley printing water-stage recorder on right bank; inpected by John

- A. Bolton and Earle Husson.

DISCHARGE MEASUREMENTS. Made from cable 100 yards below gage or by wading.

CHANNEL AND CONTROL. Solid ledge overlain with coarse gravel; probably 

permanent.

EXTREMES OP DISCHARGE. Maximum stage during year, from water-stage 

recorder, 8.30 feet at 12.30 a. m., March 22 (discharge, 9,600 second-^eet) J 

minimum stage, from water-stage recorder, 1.41 feet from 4 a. m. to 10 p. m., 

September 10 (disqharge, 63 second-feet).

1916-1921: Maximum stage, from water-stage recorder, 9.87 feet at

x 11 a, m. June 12, 1917 (discharge, 13,500 second-feet); minimum discharge, 

56 second-feet, from 11 a. m. September 11 to 8 a. m. September 13, 1916.,

ICE. Stage-discharge relation affected by ice.

REGTTLATioN.-^-Large diurnal fluctuation due to logging operations during spring, 

Seasonal distribution of flow slightly affected by storage.

ACCURACT. Stage-discharge relation changed at time of spring break-up. Rating 

curve used before March 10 fairly well defined between 70 and 600 second r 

feet and well defined between 600 and 6,000 second-feet; rating curve use<i 

thereafter very well defined between 200 and 7,500 second-feet. Stagedischarge relation affected by ice from December to March and by logs 

during April. Operation of water-stage recorder satisfactory except for 

periods indicated in footnote to daily-discharge table. Daily discharge 

ascertained by applying to rating table mean daily gage height obtained 

by averaging hourly gage heights, or for day of considerable variation in 

stage, by averaging the hourly discharge. Records good except those for 

periods of ice and log effect, which are fair.

NOTE. Discharge, Dec. 27 to Mar. 9, determined from gage-heights corrected for ice effect by means of 

three discharge measurements, study of gage-height graph and weather records, and comparison with records 

of flow for the stations on Hudson River at North Creek and Indian River near Indian Lake. Water-stage 

recorder did not operate Dec. 27 to Jan. 2, Jan. 11-14,and March 8; discharge determined by comparison 

with records as stated above. Stage-discharge.relation affected by logs Apr. 1-26; discharge estimated on 

basis of one discharge measurement and comparison with the record at North Creek.

HUDSON RIVER AT NORTH CREEK, N. 7.

LOCATION. At two-span steel highway bridge in village of North * Creek, 

Warren County, immediately above mouth of North Creek.

DRAINAGE AREA. 804 square miles.

RECORDS AVAILABLE. September 21, 1907, to September 30, 1921.

GAGE. Chain on upstream side of left span of the bridge; read by William 

Alexander.

DISCHARGE MEASUREMENTS. Made from the upstream side of the highway 

bridge.

CHANNEL AND CONTROI,. Heavy gravel; fairly permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 8.20 feet at 

5.30 p. m., March 21 (discharge, 12,800 second-feet); minimum stage 

recorded, 2.05 feet at 7.30 a. m.; July 4 (discharge, 210 second-feet).

1907-1921: Maximum stage recorded, 12.0 feet during the evening of 

March 27, 1913 (discharge, about 30,000 second-feet); minimum discharge, 

168 second-feet at 7.05 a. m., September 30, 1913.

ICE. -Stage-discharge relation affected by ice.

REGULATION, The numerous lakes and ponds in the basin of the upper Hudson 

especially the reservoir at Indian Lake, have a decided effect on the lowwater flow. Many of the reservoirs are used to make flood waves in the 

spring in connection with log driving.

AcctrRApT.-^Stagerdischarge relation practically permanent; .affected by ice 

from January to March. Rating curve well defined between 250 and 6,000 

second-feet. Gage jead to half-tenths twice daily. Daily discharge ascerr 

taiued by applying mean' daily'gage height to rating table. Open-water 

records good except for log-driving season when mean daily gage height 

computed from two gage readings each day may be in error owing to large 

variations in stage caused by operation of sluice gates in logging dams above

. station. -Winter recordsvf-air.. .-- .^ .

146 SURFACE WATER SUPPLY, 1921, PART I.

HUDSON RIVER AT HADLEY. N. Y.

LOCATION. In Hadley, N. Y., one-fourth of a mile above mouth of Sacandaga 

River and dam of Neura Paper Co. and just below mouth of Lake Luzerne 

outlet.

DRAINAGE AREA. 1,660 square miles (from Fourth Annual Report of New York 

State Water-Supply Commission).

RECORDS AVAILABLE. July 15 to September 30, 1921. Comparable records at 

station at Thurman, 13 miles above, September 1, 1907, to September 30, 

1920.

GAGE. Gurley 7-day graph water-stage recorder installed August 9, 1921, in 

timber well and shelter on right bank; prior to August 9 temporary vertical 

staff gage about 200 feet upstream. Temporary gage read by engineers 

during construction of automatic gage installation. Water-stage recorder 

inspected by J. F. Kelly.

DISCHARGE MEASUREMENTS. Made from cable 100 yards above gage.

CnANNBii AND CONTROL. Solid ledge about 200 feet below gage, with some large 

boulders; probably permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during period, 4.31 feet 

(temporary staff gage reading) at 9 a. m. July 15 (discharge, 2,920 secondfeet); minimum stage from water-stage recorder, 2.12 feet at midnight September 5 (discharge, 724 second-feet).

ICE. Stage-discharge relation affected by ice.

REGULATION, Discharge regulated to some extent by storage reservoirs at 

Indian, Schroon, and Brant lakes and by mills on Schroon River.

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

between 600 and 30,000 second-feet. Operation of water-stage recorder 

satisfactory except as indicated in footnote to daily-discharge table. Daily 

discharge ascertained by applying to rating table mean daily gage height 

determined from staff gage readings or by inspection of gage-height graph, 

or for days of considerable fluctuation, by averaging discharge for intervals 

of the day. Records good.

HUDSON RIVER AT SPIER FALtS, N. Y.

LOCATION. Half a mile below Spier Falls dam and power plant of Adirondack 

Electric Power Corporation, Saratoga County, and 111 miles below mouth of 

Sacandaga River.

DRAINAGE AREA, 2,800 square miles (measured on topographic maps).

RECORDS AVAILABLE. October 7, 1912, to September 30, 1921.

GAGE. Gurley 2-day water-stage recorder on right bank; inspected by T. F* 

Malone, chief operator of power plant.

DISCHARGE MEASUREMENTS. Made from cable 1,000 feet below gage.

CHANNEL AND CONTROL. Bed composed of coarse gravel and boulders. Control probably permanent.

EXTREMES OP DISCHARGE. Maximum stage during year, from water-stage 

recorder, 11.79 feet at 1.15 p. m., March 22 (discharge, 32,800 second-feet); 

minimum stage, 0.98 foot at 2 a. m. and 4.30 to 5.30 a. m., September 30 

(discharge, '152 second-feet).

1912-1921: Maximum stage from water-stage recorder, 18.59 feet at 

12.25 a. m. March 28, 1913 (discharge, about 89,100 second-feet); minimum, 

stage, 0.12 foot at 4 p. m. September 23, 1917 (discharge, about 5.5 

secondnfeet).

ICE. Stage-discharge relation affected by ice during extremely cold periods.

REGULATION. Large diurnal fluctuation is caused by operation of Spier Falls, 

power plant. Seasonal flow affected by storage at Indian Lake and many 

small lakes and reservoirs in the upper part of drainage basin.

DIVERSIONS. Water is diverted from Hudson River through the Glens Falls 

canal. A portion flows north into Lake Champlain. No correction haa 

been made for this diversion.

ACCURACY. Stage-discharge relation practically permanent; not affected by 

ice during year. Rating curve well denned for all stages except in vicinity 

of 9 feet, where curve may be 4 or 5 per cent too large. Operation of waterstage j-ecorder satisfactory throughout year. Daily discharge ascertained 

by averaging the results obtained by applying hourly gage height to rating 

table. Records good.

COOPERATION. Record of hourly discharge computed by engineers of International Paper Co.

HTTDSOir AT MEdBAHICVILLfc, IT. Y.

LOCATION. 'At Duncan dam of , West Virginia Pulp & Paper Co. in Mechanicville, Saratoga County^ 3)700 feet above mouih of Anthony JCUl, 1| miles 

below mouth of Hoosic Eiver, and 9 miles above;ihouth of Mohawk River.

DRAINAGE ABBA. 4,500 square miles.

RECOEDS AVAILABLE. 1888 to September 30, 1921.

GAGE. Water-stage recorder at the dam, installed in 1910; previous to that 

date, staff gage.

COMPUTATIONS OF DISCHABGE. Discharge over spillway determined from a 

rating curve based on coefficients derived by United States Geological 

Survey for dams of ogee section; Discharge through turbines computed from 

records of their operation. Discharge at lock and through Barge Canal 

turbines at lock computed from records of the number of lockages a day.

EXTBEMES OF DISCHARGE. Maximum daily discharge during year, 33,000 secondfeet, March 22; minimum daily discharge, 715 second-feet, June 26.

1888-1921 : Maximum discharge recorded, 120,000 second-feet at 6 a. m. 

March 28, 1913. The plant is occasionally shut down and the now of the 

river stored in the pond so that the discharge below the station at these times 

becomes practically zero.

DIVEBSIONS, Water is diverted from Hudson River through the Glens Falls feeder 

and the old Champlain Canal into the summit level of the Barge Canal. 

A portion flows north into Lake Champlain. No correction has been made 

for this diversion.

COOPERATION. Discharge over the spillway and through turbines of the West 

Virginia Pulp & Paper Co. furnished by Mr. W. J. Barnes, engineer of the 

company. Record of lockages from office of State superintendent of public 

works.

HUDSON BIVEB BASIN. 151

OPALESCENT RIVES BELOW FLOWED LAND, NEAR TAHAWTJCS, N. Y.

LOCATION. In Newcomb Township, Essex County, one-eighth mile below dam 

at outlet of Flowed Land, 8 miles above confluence with Hudson River, and 

14 miles northeast of Tahawus post office.

DRAINAGE AREA. 9.0 square miles (measured on topographic maps).

RECORDS AVAILABLE. November 25, 1920, to September 30, 1921.

GAGE. Staff gage in two sections on left bank; the lower inclined, the upper 

vertical.

DISCHARGE MEASUREMENTS. Made by wading above gage at low and medium 

stages; no equipment installed for high-stage measurements.

CHANNEL AND CONTROL. Channel very rough, with many boulders; precipitous 

below gage. Control is a rock ledge overlain by large boulders a few feet 

below1 gage.

EXTREMES OF DISCHARGE. Maximum stage recorded during period, 7.8 feet 

at 4 p. m. March 21 (discharge not determined); minimum stage recorded, 

1.35 feet at 9.30 a. m. May 11 and 9 a. m. June 4 (discharge, 0.8 second-foot).

ICE. Stage-discharge relation probably not seriously affected by ice.

REGULATION. Flow regulated by storage in Flowed Land. Flow in spring 

frequently affected by flood waves caused by releasing water from Flowed 

Land during log-driving operations.

DIVERSIONS. None, except that at high stages of Flowed Land there may be 

some leakage through dam at head of Calamity Brook and out of the 

drainage area. No record of leakage available.

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

between .5 and 150 second-feet; extended above and below. , Gage read to 

half-tenths once daily. Daily discharge ascertained by applying daily 

gage height to rating table. For days of great fluctuation mean daily gage 

height was determined from hydrographs. Records good except for stages 

below 5 and above 150 second-feet when they are subject to error.

COOPERATION. Gage readings made by employees of New York State Conservation Commission.

Precipitation records for this vicinity are being obtained at a station including 

standard shelter,, maximum and minimum thermometers, rain gage, snow tube 

and stake, density bucket, and scales. Part of this equipment was furnished by 

United States Weather Bureau.

natural flow from the basin, because of artificial storage in Flowed Land.
HUDSON EIVEB BASIN.

INDIAN LAKE RESERVOIR NEAR INDIAN LAKE, N. T.

LOCATION. At masonry dam at outlet of Indian Lake, 2 miles south of Indian 

Lake village, Hamilton County, and 7£ miles above mouth of Indian 

Biver.

DRAINAGE AREA. 131 square miles, including about 9.3 square miles of water 

surface of Indian Lake at the elevation of crest of spillway (measured on 

topographic maps).

EECORDS AVAILABWE. Records of stage and gate openings from July 22,1900, to 

September 30, 1921.

GAGES. Elevation of water surface in reservoir is determined by chain gage 

on dam near gate house; prior to November 17, 1911, a staff gage was used 

at same site. Mean elevation of crest of spillway is at gage height 33.38 

feet. Widths of sluice gate openings determined by gage scales at sides of 

gate stems inside gate house. Gages read by Lester Sevarie.

EXTREMES OP STAGE. Maximum elevation of water surface in reservoir, 35,35 

feet April 18; minimum elevation, 13.75 feet October 27 and 28.

1900-1921: Maximum elevation recorded, 38.8 feet March 28, 1913; 

minimum elevation, 2.0 feet March 9-18, 1907, and January 3-17, 1910.

REGULATION. At ordinary stages the discharge is completely regulated by the 

operation of the sluice gates. Water is held in storage until needed to supplement the flow of the upper Hudson during the low-water period. The 

storage capacity is about 4.7 billion cubic feet, equivalent to a flow of about 

600 second-feet for 90 days.

INDIAN RIVER NEAR INDIAN LAKE, N. Y.

LOCATION. Three-fourths of a mile below dam at outlet of Indian Lake, 2 miles 

south of Indian Lake village, Hamilton County, 1 mile above mouth of 

Big Brook, and 6| miles above mouth of Indian River.

DRAINAGE AREA. 132 square miles (measured on topographic maps).

RECORDS AVAILABLE. July 1, 1912, to June 30, 1914; June 5, 1915, to September 30, 1921; also miscellaneous measurements in 1911.

GAGE. Gurley 7-day graph water-stage recorder; installed August 30, 1916, on 

right bank at same datum as staff gage previously used. Recorder inspected 

by Lester Sevarie.

DISCHARGE MEASUREMENTS. Made from cable 75 feet below gage or by wading.

CHANNEL AND CONTROL. Control is a reef of coarse gravel; permanent.

EXTREMES OP DISCHARGE. Maximum -stage during year, from water-stage 

recorder, 5.76 feet at 3.30 p. m. May 21, during a log drive (discharge, 1,990 

second-feet); minimum stage, from water-stage recorder, 0.33 foot from 6 

p. m. November 8 to 8 a. m. November 9 (discharge, 7.9 second-feet).

1912-1921: Maximum stage recorded, 7.8 feet at 4 p. m. March 28, 1913 

(discharge, 3,460 second-feet); minimum stage from water-stage recorder, 

0.04 foot at 5 a. m. October 2, 1918 (discharge, 1.3 second-feet).

ICE. Stage-discharge relation not affected by ice.

REGULATION. Discharge is regulated by operation of the sluice gates at Indian 

Lake dam.
HUDSOH RIVEB BASIN.

ACCUHACY. Stage-discharge relation permanent. Rating curve fairly w*U defined between 5 and 15 second-feet, and well defined between 15 and 1,500 

second-feet. Operation of water-stage recorder satisfactory except for 

periods indicated in footnote to daily-discharge table. Daily discharge 

ascertained by applying to rating table mean daily gage height determined 

by inspection of recorder graph, or for days when there were changes in 

openings of sluice gates at Indian Lake dam, by averaging the discharge for 

bi-hourly intervals of the day. Records good except for periods for which 

recorder did not operate satisfactorily.

The following discharge measurement was made by Currier and Harrington: 

January 16, 1921: Gage-height, 0.49 foot; discharge 18.1 second-feet.

LOCATION. Half a mile below Walloomsac River and 1J^ miles above Owl Kill

and Eagle Bridge, Rensselaer County.

DRAINAGE AREA.^512 square miles (measured Oft topographic maps). 

RECORDS AVAILABLE. August 13, 1910, to September 30, 1921. September 25,

1903, to December 31,1908, comparable record at Buskirk, 4 i$Dtes below. 

GAGE. Chain gage on left bank near farm house of James Russell. Gage read

by Dennis Mironowiez and Michael Murrane. ; 

DISCHARGE iiEAS^^S|*N*s.-^Miftde from cable half a mile betow gage or by

CHANNEL AND CON.TROL. Gravel; somewhat shifting.

EXTREMES OF DISCHARGE. ^Maximum stage recorded during year, 11.05 feet 

at 7 a. m. March 10 (discharge, 11,300 second-feet) ; minimum stage recorded, 

, 2.30 feet at 7 a. m. September 26 (discharge^ 66 second-feet) . 

1910-1921: Maximum stage recorded, 13.5 feet at 7.30 a. m. July 9, 1915 

(discharge, 16,700 second-feet); possibly higher stage previous to August 17, 

1914, as gage was Inaccessible at extremely high water. Minimum discharge i 

recorded, practically zero at 5 p. m. September 14, 1913.

ICE. Stage-discharge relation affected by ice during most years.

REGULATION. Flow affected by storage on Walloomsac River and at Hoosick 

FallSj 2 miles above gage.

ACCURACY. Stage-discharge relation practically permanent during year except 

as i affected by ice, January arid February. Rating curve well defined 

between 150 and 9,000 second-feet. Gage read to half-tenths twice daily. 

Daily discharge ascertained by applying mean daily gage height to rating 

table. Records good, except for periods of low water, when semidafly gage 

height may not indicate the true mean, owing to abnormal fluctuation in 

stage, and for periods of ice effect, for which records are fair.

and surveyor. A tape gage at highway bridge was used 1905 to 1913.

DISCHARGE MEASOREMENTS*. Made from downstream side of .highway bridge 

or by wading, *

CHANNEL AND CONTROL. Small boulders and coarse gravel; probably permanent under present regulated flood flows.

EXTREMES OF DISCHARGE. -Maximum stage dur-ing yfear, from water-staife 

recorder, 5.27 feet at 9 a. m. March 22 (discharge, 6,400 second-feet); minimum stage from water-stage recorder, 1.25 feet at 3 a. m. June 27 and 3 

a..m. July 11 (dischfarge, 164 second-?feet),,

ICE. Stage-discharge relation prob>bly not affected by ice.

REGULATION. Seasonal flow regulated by storage in Hinckley, reservoir, Consolidated Water Cq.'s reservoir on Black Creek at Gray, and several small 

lakes. Diurnal fluctuation caused by operation of mills -and power plants 

upstream.

DIVERSIONS. Water supply for tJtica is diverted from Hinckley reservoir by 

Consolidated Water Co. Water is diverted below Trenton Falls power 

plant during navigation season, through Nihemile feeder and Ninemile 

Creek, into toe Barge Canal. See record for Ninemile feeder (p. 170).

ACCURACY. Stage-discharge relation permanent. Rating curve very well defined between 300 and 3,000 second-feet. Operation of water-stage recorder 

satisfactory except for few short periods. Daily discharge ascertained by 

use of discharge integrator. Records good.

RECORRS AVAiLABLE.-i-'Januaa:y, 1898, to Septeniber, 1920.

DETERMINATION OF DISCHARGE. Actual flow at Paterson determined by engineers of the Society for Establishing Useful Manufactures. This consists 

of discharge over spillway computed from a theoretic formula, discharge 

through turbines, determined from manufacturers' ratings, discharge through 

the Dyers' pipeline, metered, and the discharge through the old race measured 

twice daily by current meter.

DiVERSIONS. Water is diverted from Passaic River above Paterson by Newark 

waterworks, Jersey City waterworks, Commonwealth Water Co., Eas t 

Orange waterworks, and Morris canal. Diversion by Newark and Jersey 

City measured by Venturi meter; diversion by'.Commonwealth Water Qb. 

and East Orange waterworks measured by piston; displacement; diversion 

by Morris canal estimated.

REGULATION. -Correction:has been made for s/fcorage in Newark and Jersey City 

storage reservoirs and in Greenwood Lake, which is a storage reservoir for 

Morris canal. No correction has been made for evaporation from the surface of the various reservoirs, which comprise about 1 per cent of the total 

drainage area.

COOPERATION. Base data furnished by John H. Cook, hydraulic engineer of the

iyi Society for Establishing Useful Manufactures, Newark waterworks, Jersey 

City waterworks, Commonwealth Water Co., and East Orange waterworks.

SOTTTH BRANCH OF RARITAN RIVER AT STAHTOIT, N. J.

LOCATION. At highway bridge near Lehigh Valley Railroad station in Stanton 

Hunterdon County, half a mile above mouth of Prescott Brook and 5 miles 

below mouth of Cakepoulin Creek.

DBAINAGE AREA. 158 square miles.

RECORDS AVAILABLE. July 2, 1903, to December 3i, 1906; and July 1, 1919, 

to September 30, 1921.

GAGE. Chain gage on downstream side of bridge near left end; read by E. H. 

Smith. Datum same as for gage used 1903-1906.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge or by 

wading.

CHANNEL AND CONTROL. Gravel bed and banks. Banks are overflowed at high 

stages. Control is slight riffle about 100 feet below bridge.

EXTREMES OF DISCHARGE. Maximum stage recorded during the period July 1, 

1919, to September 30, 1921, about 10 feet at 8 p. m. July 21 and midnight 

July 22, 1919, estimated from hydrograph (discharge not determined).; minimum stage recorded, 1.85 feet at 5 p. m. September 16, 1921 (discharge, about 

24 second-feet).

1903-1906 and 1919-1921: Maximum stage recorded 10.5 feet, October 9, 

1903 (discharge not determined). The stage of 11.0 feet March 7, 1904, probably caused by backwater from ice. Minimum stage, that recorded in 1921.

ICE. Stage-discharge relation affected by ice.

REGULATION. Daily distribution of flow slightly affected by small water powers 

above.

ACCURACY. Stage-discharge relation probably permanent except when affected 

by ice. Rating curve well defined between 35 and 1,200 second-feet. Gage 

read to quarter-tenths twice daily. Daily discharge ascertained by applying 

daily mean gage height to rating table. Records fair.

Kline. Elevation of gage zero, 188.50 feet, United States Geological 

Survey datum.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

CHANNEL AND CONTROL. Right bank high and not subject to overflow; left low 

and stream begins to overflow the canal towpath at stage of 6.8 feet. Bed 

composed of gravel. Low-water control is a slight riffle 700 feet below gage; 

may shift occasionally. Control for high stages is probably at the Pennsylvania Railroad bridge 900 feet below gage; probably permanent.

EXTREMES OP DISCHARGE. Maximum stage during year, estimated from hydrograph, 6.6 feet at 10 a. m. May 5 (discharge, 11,900 second-feet) minimum 

stage, -0.64 foot on September 5, 6, and 10 (discharge, 255 second-feet).

ICE. Stage-discharge relation usually affected by ice.

DIVERSIONS. During navigation season water is diverted past the gage through 

the Schuylkill Navigation Co.'s canal, which follows along the left bank.

ACCURACY. Stage-discharge relation permanent throughout year. Rating 

curve fairly well defined below 15,000 second-feet. Gage read to hundredths 

twice daily. Daily discharge ascertained by applying mean daily gage 

height to rating table. Records good, except for low stages, for which 

they are fair.

230 SURFACE WATER SUPPLY, 1921, PART I.

BRANDYWINE CREEK AT CHADDS, FORD, PA.

LOCATION. At two-span steel bridge of Pennsylvania Railroad at Chadds Ford, 

Delaware County.

DEAINAGE AREA. 285 square miles.

RECORDS AVAILABLE. 'August 1, 1911, to September 30, 1921. Records prior 

to October 1, 1918, are contained in annual reports of the Water Supply 

Commission of Pennsylvania.

GAGE. -Chain gage attached to upstream side of bridge; read by H. W. Guest. 

Elevation of gage zero, 150:18 feet, United States Geological Survey datum. 

A Sanborn water-stage recorder on upstream end of pier, is referred to the 

chain gage datum.

DISCHARGE MEASUREMENTS. Made from upstream side of bridge.

CHANNEL AND CONTROL. Right bank is low and the stream begins to overflow 

a flat 700 feet wide at a stage of about 6 feet. Left bank high and not subject to overflow. Bed is composed of mud, gravel, and stones. Control is 

the first of a series of low riffles, where the bed is composed of gravel, extending downstream from about 150 feet below gage; practically permanent.

EXTREMES OP DISCHARGE. Maximum stage during year, estimated from hydrograph, 6.0 feet at 1 p. m. December 1 (discharge, 2,260 second-feet); minimum 

stage 0.48 foot at 6 p. m. September 3 and 10 (discharge, 69 second-feet).

ICE. Stage-discharge relation usually affected by ice.

REGULATION. Fluctuations in stage during low water are caused by the operation 

of a mill above station.

ACCURACY. Stage-discharge relation permanent throughout year. Rating 

curve well defined between 100 and 2,000 second-feet. Chain gage read to 

hundredths twice daily. Daily discharge ascertained by applying to rating 

table mean daily gage height, computed from chain gage readings. Records 

good.

LOCATION. If miles below Tioughnioga River, 2 miles by road below Chenango 

Forks post office, Broome County, and llf miles above Binghamton and 

mouth.

DRAINAGE AREA. 1,420 square miles (measured by State Conservation Commission of New York). See "Diversions,"

RECORDS AVAILABLE. ^November 11, 1912, to September 30, 1921.

GAGE. Stevens water-gage recorder on left bank on the farm, of Erastus Ingraham June 13 to September 30, 1921. October 1 to June 13, a Gurley 

7-day graph water-gage recorder was in use.

DISCHARGE MEASUREMENTS. Made from cable 300 feet above gage or by 

wading.

CHANNEL AND CONTROL. Sand, gravel, and small cobblestones; practically 

permanent.

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

recorder, 9.60 feet at 3 a. m. March 10 (discharge, 17,600 second-feet); 

minimum stage, 2.49 feet from 4 to 7 p. m. September 10 and from 8 to 10 

p. m. September 11 (discharge, 225 second-feet).

1912-1921: Maximum stage recorded, 13.7 feet on afternoon of March 

27, 1913 (discharge, 35,500 second-feet); minimum stage recorded, 2.20 

feet several times in August and September, 1913 (discharge, 92 second-feet))'

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. The run-off from 87.3 square miles at head of Chenango River 

and from 15.7 square miles at head of Tioughnioga River is stored in reser* 

voirs and, except for discharge over the spillways, is diverted out of the 

drainage area to the Erie Canal. The drainage area given for Chenango 

River does not include these two areas.

ACCURACY. Stage-discharge relation practically permanent. Revised rating 

curve, fairly welVdefined between 200 and 20,000 second-feet, used throughout year. Record from Gurley gage unsatisfactory owing to the clock

 stopping frequently. Discharge estimated during these periods. Operation of Stevens water-stage recorder satisfactory. Daily discharge ascertained by applying to rating table, mean daily gage height, determined by 

inspecting gage-height graph or for days of considerable fluctuation, by 

. averaging the. discharge for intervals of the day. Records good except 

for periods of estimates and when stage-discharge relation was affected

 i by>uce, for which they are fair.

WAPWALLOPEKT CREEK NEAR WAPWALLOPEK, PA.

LOCATION. At single-span steel highway bridge known as Harts Bridge, 3i miles 

southeast of Wapwallopen, Luzerne County, and 3| miles above mouth 

of creek.

DRAINAGE AREA. 46 square miles.j

RECORDS AVAILABLE. October 24, J1919, to September 30,1921.

GAGE. Chain gage attached to downstream side of bridge; read by Calvin P. 

Readier.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge or by 

wading.

CHANNEL AND CONTROL. Left bank is high and not subject to overflow; right 

is of medium height and is overflowed at extremely high stages. Bed is 

composed of gravel and boulders. Control is a riffle about 1,000 feet below 

gage, where bed is composed 4>f a compact formation of coarse gravel and 

boulders; probably permanent.

EXTREMES OP DISCHARGE. Maximum stage during year, estimated from hydrograph, 4.2 feet at 9 p. m. March 3 (discharge, 580 second-feet); minimum 

stage, 0.90 foot at 6 p. m. July 26 and several times in September (discharge, 

5 second-feet.)

ICE. Stage-discharge relation usually affected by ice.

REGULATION. Operation of gristmills above station may cause variation in 

stage during low stages. Theife is very little storage at mill dam 1J miles 

above gage; at dam 3| miles iabove gage there is some storage, and flow 

during part of day at time of lovtf water can probably be stored.

ACCURACY. Stage-discharge relation permanent throughout year except when 

affected by ice. Rating curve i airly well defined between 15 and 300 secondfeet. Gage read to hundredth twice daily. Daily discharge ascertained 

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

for extreme stages, for which they are fair.

COOPERATION. Station is maintained in cooperation with M. O. Leighton, 

consulting engineer, Washington, D. Ci ?

The following discharge measurement was made by H. J. Mclntyre: 

May 12,1921: Gage height, 1.80 feet; discharge, 68 Second-feet.

SURFACE WATER SUPPLY, 1921, PART I. 283

POTOMAC RIVER BASIN.

POTOMAC RIVER AT POINT OF ROCKS, MD.

LOCATION. At steel highway bridge at Point of Rocks, Frederick County, onethird mile below Catoctin Creek and 6 miles above Monocacy River.

DRAINAGE AREA. 9,650 square miles.

RECORDS AVAILABLE. February 17, 1895, to September 30, 1921.

GAGE. Chain attached to downstream side of left span of bridge; read by W. W. 

Compher. Datum constant since September 2, 1902; prior to this date 

datum was 0.45 foot higher than at present. Sea-level elevation of gage 

datum, 200.54 feet.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Practically permanent. Control is a ledge a few 

hundred feet below station, the ledge extending completely across the river 

except for one relatively unimportant channel.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 13.6 feet at 

10 a. m. May 6 (discharge, not determined); minimum stage, 0.84 foot at 

10 a. m. September 1 (discharge, not determined).

1895-1921: Maximum stage recorded, 29 feet on March 2, 1902 (discharge, 219,000 second-feet); minimum stage, 0.38 foot on September 10, 

1914 (discharge, 540 second-feet).

The crest of the flood of June 2, 1889, as determined by the U. S. Army 

Engineers from high-water marks, reached a stage of 40.2 feet (discharge, 

325,000 second-feet).

ICE. Stage-discharge relation' seldom affected by ice.

DIVERSIONS. The Chesapeake & Ohio Canal parallels the Potomac on the 

Maryland side. The average discharge of the canal is 75 to 100 second-feet. 

The discharge is not included in the following tables.

REGULATION. Fluctuation at extreme low stages has been noted and is probably 

caused by the operation of power plants on the upper Potomac and tributaries.

ACCURACY. Stage-discharge relation below gage height 2.0 feet, changed last

part of August owing to construction of a fish trap; affected by ice from

> January 19-28. Daily discharge withheld pending making of additional

discharge measurements. Gage read to hundredths once daily; during

high water read oftener.

RAPPAHANNOCK RIVER BASIN.

RAPPAHANNOCK RIVER NEAR FREDERICKSBURG, VA.

LOCATION. At rear of MeWhirt farm, li miles above dam of Spottsylvania 

Power Co. and 3J miles above Fredericksburg. Spottsylvania County.

DRAINAGE AEEA. 1,590 square miles.

RECORDS AVAILABLE. September 19, 1907, to September 30, 1921.

GAGE. Vertical staff on right bank; installed November 4, 1913, to replace 

chain gage destroyed October 31, 1913. Original gage was a vertical staff 

which was destroyed February 14, 1908, and replaced February 20, 1908, 

by a chain gage under the cable. All three gages at practically the same 

location and referred to same datum. Gage read by Charles Perry.

DISCHARGE MEASUREMENTS. Made from cable at gage or by wading, about 1 

mile above gage.

CHANNEL AND CONTROL. Bed composed of boulders; somewhat rough. One 

channel. Banks wooded; water overflows right bank at stage about 15 

feet and left bank at about 12 feet. Current sluggish at extremely low 

water. Control is a rocky section a few hundred feet below the gage; 

practically permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 7.17 feet at 

9 a. m. May 13 (discharge, 16,800 second-feet); minimum stage, 0.54 foot 

at 11.30 a. m. August 29 (discharge, 123 second-feet).

1907-1921: Maximum stage recorded, 11.45 feet at noon April 11, 1918 

(discharge, 38,500 second-feet); minimum stage recorded, 0.30 foot at 3 

p. m. August 21, 1914 (discharge, 72 second-feet).

ICE. Ice forms near gage but seldom in sufficient quantity at control to affect 

stage-discharge relation.

ACCURACY. Stage-discharge relation practically permanent; not affected by 

ice during year. Rating curve well denned between 100 and 27,000 secondfeet; extended beyond these limits. Gage read to hundredths once daily; 

gage heights July 1 to September 20 may be subject to some error owing to 

unstable condition of gage during this period. Daily discharge ascertained 

by applying gage height to rating table. Records good except those from 

July 1 to September 20, which" are fair.
