SURFACE WATER SUPPLY OF THE NORTH ATLANTIC 

COAST BASINS, 1912.

By C. C. BABB, C. C. COVERT, and J. G. MATHEES.

AUTHORIZATION AND SCOPE OF WORK.

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

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

the calendar year 1912.

The data presented in these reports were collected by the United 

States Geological Survey under authority implied in the organic law 

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

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

survey and the classification of public lands and examination of the geological structure, mineral resources, and products of the national domain.

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

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

1895, successive sundry civil bills passed by Congress have carriecj, 

the following item and appropriations:

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

for the investigation of underground currents and artesian wells, and for the preparation of reports upon the best methods of utilizing the water resources. 

Annual appropriations for the fiscal year ending June 30 

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

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

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

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

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

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

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

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

In the execution of the work many private and State organizations 

have cooperated, either by (a) furnishing data or (b) by assisting in 

collecting the data. Acknowledgments for cooperation under class 

u a" are made in connection with the description of each station 

affected, and for class "b" on page 16.

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

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

7
8 SUBFACE WATER SUPPLY, 1912, PAST I.

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

Hawaiian Islands. During 1912, gaging stations were maintained by 

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

and many discharge measurements were made at other points. In 

connection with this work data were also collected in regard to 

precipitation, evaporation, storage reservoirs, river profiles, and 

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

available in the regular water supply papers from time to time.

PUBLICATIONS.

For each calendar year there has been prepared a report embodying 

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

reports containing stream-flow measurements prior to 1904 has been 

published as Water-Supply Paper 119. Circulars are also available 

giving complete lists of the gaging stations maintained by the Survey 

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

country.

Prior to 1902, gage heights and discharge measurements were 

published in water-supply papers or bulletins and estimates of 

monthly discharge in annual reports; since 1902, both classes of data 

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

published in 12 parts, as shown in the following table:

DEFINITION OF TERMS.

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

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

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

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

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

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

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

follows:

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

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

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

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

factors given in the following table of equivalents.

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

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

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

regards time and area.
12 SUEPACB WATER SUPPLY, 1912, PAET I.

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

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

period were conserved and uniformly distributed on the surface. It 

is used for comparing run-off with rainfall, which is usually expressed 

hi depth in inches.

An "acre-foot" is equivalent to 43,560 cubic feet, and is the quantity required to cover an acre to the depth of 1 foot. The term is 

commonly used in connection with storage for irrigation.

CONVENIENT EQUIVALENTS.

The following is a list of convenient equivalents for use in hydraulic 

computations:

EXPLANATION OF DATA.

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

so far as available, are given: Description of the station, list of discharge measurements, table of daily gage heights, table of daily discharge, table of monthly and yearly discharge and run-off. For stations located at weirs or dams the gige-height table is omitted.

In addition to statements regarding the location and installation of 

current-meter stations the descriptions give information in regard to 

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

height to discharge, covering such points as ice, logging, shifting channels, and backwater; also information regarding diversions which
14 STTKFACE WATEI, SUPPLY, 1912, PABT I.

decrease the total flow at the measuring section. Statements are also 

made regarding the accuracy and reliability of the data.

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

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

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

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

water above the zero of the gsge. All gage heights affected by the 

presence of ice in the streams cr by backwater from obstructions are 

published as recorded, with suitable footnotes. The rating table is

not applicable for such periods unless the proper corrections to the

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

that the zero of the gage is placed at an arbitrary datum and has no 

relation to zero flow or the bottom of the river. In general the zero 

is located somewhat below the lowest known flow, so that readings 

of negative values shall not occur.

The discharge measurements and gage heights are the base data 

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

The rating table gives, either directly or by interpolation, the discharge in second-feet corresponding to every stage of the river recorded 

during the period for which it is applicable. It is not published in 

this report, but can be determined from the tables of daily gage 

height and daily discharge by plotting gage height in feet as ordinates and discharge in second-feet as abscissas.

The table of daily discharge gives the discharge in second feet 

corresponding to the observed gage heights as determined from the 

rating tables.

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

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

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

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

water surface was at crest height, and the corresponding discharge 

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

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

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

which are defined on pages 11 and 12, are based.

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

description of station, have been collected by the methods commonly 

used at current-meter gaging stations and described in standard textbooks. Plate I shows typical gaging stations. Plate II shows current meters used in the work.

ACCURACY AND RELIABILITY OF FIELD DATA AND 

COMPARATIVE RESULTS.

The accuracy of stream-flow data depends primarily on the natural 

conditions at the gaging station and on the methods and care with 

which the data are collected. Errors of the first group depend on the 

degree of permanency of channel and of permanency of the relation 

between discharge and stage.

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

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

due to misinterpretation of stage and flow data.

In order to give engineers and others information regarding the 

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

daily discharge tables, stating the probable accuracy of the rating 

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

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

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

The accuracy column in the monthly discharge table does not 

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

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

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

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

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

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

Even though the monthly means for any station may represent 

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

gage, the figures showing discharge per square mile and depth of runon8 in inches may be subject to gross errors which result from including in the measured drainage area large noncontributing districts or 

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

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

as a rule not feasible to make adequate correction.

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

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

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

station and should not be used for other than preliminary estimates.
16 SURFACE WATER SUPPLY, 1912, PART I.

The determinations of daily discharge allow more detailed studies of 

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

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

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

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

COOPERATION.

All gaging stations in Maine were maintained in cooperation with 

the Maine State Water Storage Commission, William T. Haines, 

Governor, chairman, and Cyrus C. Babb, chief engineer.

Hydronietric work in Vermont and Massachusetts has been carried 

on under a cooperative agreement between the governors of the States 

and the Director of the United States Geological Survey.

In New York hydrometric work is carried on in cooperation with 

the State Conservation Commission and also with the State engineer

and surveyor.

DIVISION OF WORK.

The field data for Maine were collected by Cyrus C. Babb, chief 

engineer, Maine State Water Storage Commission, assisted by F. E. 

Pressey, assistant engineer; the ratings and special studies were made 

by C. C. Babb, assisted by F. E. Pressey and by H. J. Jackson, assistant engineer. Data were "prepared for publication and the estimates of flow during the period when the relation of gage height to 

discharge was affected by ice were made by H. J. Jackson. The computations were made under the direction of H. J. Jackson by C. L. 

Batchelder, G. A. Wallace, and M. I. Walters.

The field data for New York and New England, outside of Maine, 

were collected under the direction of C. C. Covert, district engineer, 

by G. K. Larrison, O. W. Hartwell, C. S. DeGolyer, G. H. Canfield, 

Frank Weber, J. G. Mathers, and R. S. Barnes. The ratings and 

studies of completed data were made by O. W. Hartwell, C. H. Pierce., 

and J. G. Mathers. The computations and ice estimates were ma~^> 

under the direction of O. W. Hartwell by C. H. Pierce, J. G. Mathe?^ 

R. S. Barnes, and W. S. Easterly. "jg

The field data for the Middle Atlantic States were collected undes 

the direction of R. H. Bolster by J. G. Mathers.

STATION RECORDS.

ST. JOHN RIVER BASIN.

ST. JOHN RIVER AT FORT KENT, MAINE.

Location. At the suspension footbridge in the town of Fort Kent, a short distance 

above the mouth of Fish River and about 15 miles below the mouth of St. Francis 

River.

Records available. October 13, 1905, to December 31, 1912. Data also in annual 

reports Maine State Water Storage Commission.

Drainage area. 4,880 square miles.

Gage. Inclined staff, 22 feet long, in two sections, attached to the new concrete pier 

nearest the New Brunswick shore of the river. The lower part of the gage is 

placed in a groove in the side of the pier; the upper part is fastened to the downstream end of the same pier. The gage datum has remained unchanged during 

the maintenance of the station.

Channel. Practically permanent; both banks high, rocky, cleared, and not subject 

to overflow except in extreme freshets.

Discharge measurements. Made from footbridge. None made during 1912.

Winter flow. Affected by ice.

Artificial control. A few dams on the upper headwaters are used for log driving; 

the operation of these dams only slightly affects the flow past the gage. No corrections applied in 1912 data.

Accuracy. Relation between gage height and discharge is occasionally affected by 

backwater caused by logs jamming on the bridge piers and, during the winter, 

by ice; otherwise the conditions for accurate determination of discharge are fair. 

A fairly good discharge rating curve has been developed.

NOTE. Daily discharge computed from a fairly well defined rating curve. Discharge Jan. 1 to Apr. 19 

estimated, because of ice, from weekly gage heights, observer's notes, climatologic records, and discharge 

of other drainage areas. It should be noted that these estimates are only approximate and may be 50 

percent or more in error. Estimated mean discharge January, 1.400 second-feet; February, 900 secondfeet; March, 1,600 second-feet; Apr. 1 to 19,3,500 second-feet. Daily discharge May 26 and Sept. 22 estimated by comparison with flow at Van Buren. Daily discharge June 16 and 30 interpolated.

ST. JOHN EIVEE BASIN. 19

ST. JOHN RIVEK AT VAN BUKEN, MAINE.

Location. At new International Bridge at Van Buren, Maine, about 14 miles above 

Grand Falls, New Brunswick.

Records available. May 4,1908, to December 31,1912. Data also in annual reports 

Maine State Water Storage Commission.

Drainage area. 8,270 square miles.

Gage. Painted vertically on second pier from Van Buren side of bridge; zero of gage 

ia 407.69 feet above sea level; daily gage heights for 1910 and 1911 were read on a 

vertical rod attached to the pier of the sawdust carrier of Hammonds mill, about 

700 feet below the International Bridge, but as published they are reduced to the 

bridge datum. Daily gage heights for 1912 were read on the gage at the International Bridge and no reduction was necessary.

Discharge measurements. Made from the International Bridge. None made 

during 1912.

Winter flow. Affected by ice.

Artificial control. The little storage above for log driving probably does not affect 

the discharge.

Accuracy. Relation between gage heights and discharge is probably not materially 

affected by the control of the stream for log driving; for the winter months an ice 

rating curve has been developed. A good open-channel discharge rating curve 

has also been constructed.

Cooperation. Station established by the International Commission, River St. John, 

but maintained since May 6, 1912, by the Maine State Water Storage Commission.

Daily gage height, in feet, of St. John River at Van Buren, Maine, for 1912.

ST. CROIX RIVER BASIN.

WEST BRANCH OF ST. CROIX RIVER NEAR BAILEYVILLE, MAINE.

Location. At highway bridge 1 mile from Baileyville railroad station, about 4 miles 

below Princeton, and about half a mile above the mouth of Tomah Stream.

Records available. May 10, 1910, to October 24, 1912, when station was discontinued. The dam under construction at Grand Falls, 3 miles below, will flood 

this station out probably early in the spring of 1913.

Drainage area. 509 square miles.
ST. CBOIX RIVEB BASIN. 21

Gage. Standard chain, attached to the floor of the bridge on the easterly span.

Channel. Practically permanent; broken by four piers of the bridge; during extreme 

high stages water is liable to flow around abutments of the bridge.

Discharge measurements. Made from downstream side of bridge.

Winter flow. River generally does not freeze completely over.

Artificial control. The lake system on West Branch is extensive and is largely 

under artificial regulation. The dams are operated both for log driving and 

storage powers below.

Accuracy. Relation between gage height and discharge probably somewhat affected 

by ice during the winter and to some extent also by backwater from log jams. 

Results of discharge measurements are too discordant to warrant publishing estimates of discharge based thereon. Discordant results may be due to effect of 

log jams, but there are no data available upon which to base an interpretation of 

the results.

NOTE. Relation of gage height to discharge probably affected by ice Tan. 1 to about Apr. 15.
SURFACE WATER SUPPLY, 1912, PART I.

MACHIAS RIVER BASIN. 

MACHIAS RIVER AT WHITNEYVILLE, MAINE.

Location. Wooden highway bridge in the town of Whitneyville; 4 miles above 

Machias; 200 feet below a storage dam.

Records available. October 17, 1903, to December 31, 1912. Data also in annual 

reports Maine State Water Storage Commission.

Drainage area. 465 square miles.

Gage. A standard chain gage installed on the wooden highway bridge October 10} 

1911. Prior to October 3, 1905, a chain gage was located on the Washington 

County railroad bridge. Backwater was occasionally experienced here, however, 

from the dam at Machias, and on October 3, 1905, a staff gage was installed on 

the highway bridge three-fourths mile farther up stream. The datum of the 

present chain gage is the same as that of the staff gage on the highway bridge.

Channel. Practically permanent.

Discharge measurements. Still made at the railroad bridge, as the section there 

is better than above. Low-water measurements may be made by wading at a 

point 200 feet above the railroad bridge.

Winter flow. River does not ordinarily freeze over at the gage, although the relation 

of gage height to discharge is more or less affected by ice.

Log driving. There is a certain amount of log driving every year and jams of short 

duration occasionally occur.

Artificial control. The gates in the storage dam immediately above the station are 

opened and closed each day during low stages of the river; as a result considerable fluctuation occurs at such times.

Accuracy. A fair rating curve has been developed except at low stages, when 

quantities are somewhat uncertain. The operations of the gates of the storage 

dam also render results somewhat uncertain.

The following discharge measurement was made by F. E. Pressey: 

March 21, 1912: Gage height, 8.25 feet; discharge, 2,850 second-feet. Considerable 

anchor ice was running during the measurement.

Daily gage Jieight, in feet, of Machias River at Whitneyville, Maine, for 1912.

road to Bangor, about a mile below the highway bridge at the old tannery dam.

Records available. July 25, 1909, to December 31, 1912. Data also in annual 

reports Maine State Water Storage Commission.

Drainage area. 140 square miles.

Gage. Standard chain, established June 2, 1910, and placed at same datum as old 

vertical gage nailed to log abutment.

Channel. Gravel, but not liable to change except in an unusual flood.

Discharge measurements. Made from downstream side of the bridge.

Winter flow. Affected by ice.

Artificial control. A few log-driving dams above the station, but the regimen of 

stream is only slightly affected by them.

Accuracy. Helation between gage height and discharge is affected by ice and to a 

certain extent, but for short periods, by backwater from log jams. A good rating 

curve has been developed under 700 second-feet. Discharge values above that 

point should be used with caution. No corrections have been made for possible 

backwater from log jams.

Discharge measurements of Union River at Amherst, Maine, in 1912.

NOTE. Daily discharge computed from a rating curve well defined between 15 and 700 second-feet. 

The curve is simply an extension above 700 second-feet and discharge values above that point should be 

used with caution. Discharge Dec. 4,1909, to Mar. 9,1910, Dec. 4,1910, to Apr. 10,1911, Dec. 4 to 9 and 

19 to 26.1911, and Dec. 30,1911, to Apr. 17,1912, estimated, because of ice, from discharge measurements, 

gage heights, gage observer's notes, climatologic records, and discharge of adjacent drainage areas:

GREEN LAKE STREAM AT LAKEWOOD, MAINE.

Location. At highway bridge half a mile below dam at outlet of Green Lake, half

a mile from Lakewood post office, and 8 miles from Ellsworth. 

Records available. July 1, 1909, to December 31, 1912. Data also in annual

reports Maine State Water Storage Commission. 

Drainage area. 47 square miles.

Gage. Seven-foot staff, nailed to right-hand abutment, upstream side of bridge. 

Channel. Practically permanent; banks not subject to overflow. 

Discharge measurements. Made from lower side of bridge. 

Winter flow. Ice does not affect the relation of gage height to discharge every year

at this station. 

Artificial control. The dam half a mile above the station at the outlet of the lake

controls the storage of the lake, and records do not show the natural flow.

The following discharge measurement was made by F. E. Pressey: 

March 22: Gage height, 3.60 feet; discharge, 206 second-feet. Relation of gage 

height to discharge affected by ice.
30 SURFACE WATEE SUPPLY, 1912, PART I.

BRANCH LAKE STREAM NEAR ELLSWORTH, MAINE.

Location. At email highway bridge immediately below the sawmill at outlet of 

Branch Lake, 5 miles from Ellsworth.

Records available. July 1, 1909, to December 31, 1912. Data also in annual 

reports Maine State Water Storage Commission.

Drainage area. 31 square miles.

Gage. Seven-foot staff nailed to right abutment downstream side of bridge. Lake 

levels are taken on 8J-foot staff nailed to corner of mill near intake of wheel.

diannel. Gravelly and permanent in natural condition; fills up with sawmill 

waste, but generally clears itself during spring freshets,

Discharge measurements. Made from highway bridge.

Winter flow. Relation between gage height and discharge affected by ice.

Artificial control. The flow from the lake is regulated in the interest of the sawmill and power plants of Ellsworth.

Accuracy. Estimates of discharge for 1912 are withheld because of uncertainty of 

the discharge rating curve after about May 15.

The following discharge measurement was made by F. E. Pressey: 

March 22, 1912: Gage height, 4.50 feet; discharge, 64 second-feet.

NOTE. Observer noted the following: Nov. 14 and 15, sawing all day 9 hours. Dec. 22 and 29, stream 

clear of ice except edges.

PENOBSCOT BIVEB BASIN. 

WEST BBANCH OF PENOBSCOT BIVEB AT MILLINOCKET, MAINE.

Location. Quakish Lake dam and the Millinocket mill of the Great Northern Paper 

Co. at Millinocket, Maine.

Records available. January 11, 1901, to December 31, 1912. Data also in annual 

reports Maine State Water Storage Commission.

Drainage area. 1,880 square miles.

Gage. Automatic recording gage at Quakish Lake dam and gages in the forebay and 

tail races at the mill.

Channel. Crest of concrete dam.

Determination of discharge. The flow is computed by considering the flow over 

the dam, the flow through the wheels, and the water used from time to time 

through the log sluices, filters, etc. The wheels were rated at Holyoke, Mass., 

before being placed in position. As the head under which they work, averaging 

about 110 feet, is much greater than the head under which they were tested, numerous tube-float measurements of flow in the channel leading to the mill have been 

made by engineers of the company, in order to determine just how much water 

the mill used under different conditions of gate opening. In addition to this, a 

series of current-meter measurements were made by the United States Geological 

Survey to check the float measurements. It is believed that by means of the 

various checks on measurements, the estimates of discharge through the wheels 

are excellent. When the flow of the river is less than 2,500 second-feet, all of the 

water generally flows through the wheels of the mill. 

29761° WSP 321 14 3
34 SUBFACE WATEB SUPPLY, 1912, PABT I.

Winter flow. No difficulty is experienced in the winter on account of ice affecting 

the estimates of discharge or the running of the wheels. Ferguson Pond, just 

above the entrance to the canal, eliminates effect from anchor ice.

Artificial control. Storage dams at the outlet of North Twin Lake and at the outlet 

of Chesuncook Lake store water on a surface of about 65 square miles with a 

capacity of about 32,000,000,000 cubic feet. Except during the time (usually in 

August) when excess water has to be supplied for log driving on the river below 

Millinoqket and for a short time during the spring freshet, run-off is regulated by 

storage.

Cooperation. Results obtained and computations made by engineers of the Great 

Northern Paper Co., who furnish these data to the Survey. For 1912 the company 

has preferred to furnish values of monthly discharge only.

PENOBSCOT RIVER AT WEST ENFIELD, MAINE.

Location. At the steel highway bridge 1 mile below the village of West Enfield, 

Maine; 1,000 feet below the mouth of Piscataquis River.

Records available. January 1, 1902, to December 31, 1912. Data also in annual 

reports of the Maine State Water Storage Commission.

Drainage area. 6,600 square miles.

Gage. Standard chain; datum unchanged.

Channel. Practically permanent; broken by four bridge piers; banks high and rocky 

and not subject to overflow.

Winter flow. Affected by ice.

Artificial control. Flow of the river since about 1900 largely controlled by storage, 

principally in the lakes tributary to the West Branch. About 1 mile above the 

station is the dam of the International Paper Co., and the Piscataquis is dammed 

near its entrance into the Penobscot. Considerable water is held above these 

two dams at night. At low stages daily fluctuations in gage heights are caused 

by variations in wheel gate openings.

Accuracy. Conditions favor the accurate determination of discharge.

Cooperation. Many of the discharge measurements are made by the students of 

the University of Maine under the direction of Prof. H. S. Boardman.

EAST BRANCH OF PENOBSCOT RIVER AT GRAND LAKE DAM, MAINE.

Location. At the dam at the outlet of Grand Lake, T. 6, Rs. 8 and 9, about 47 miles 

above the mouth of the river.

Records available. April 18 to July 12, 1912. Records simply show fluctuation of 

the level of the lake.

Drainage area. 496 square miles. Includes Chamberlain Lake drainage area, 270 

square miles.

Gage. Staff gage at the dam.

Channel. The dam at the outlet of Grand Lake is a timber crib about 185 feet long 

between ledge abutments and affords a head of 14 feet. There are five gates 8 

feet wide and one sluice gate 17 feet wide. The elevation of gate sills is about 

641.2 feet.

Discharge measurements. None made at this station.

Artificial control. The dam at this station, as well as the one at the outlet of Chamberlain Lake, is operated in the interests of log driving. The gates are generally 

closed down in the spring as soon as the ice goes out, and the spring freshet flow 

is thus stored. The gates are subsequently manipulated when running logs, and 

at the end of the drive are left open for the balance of the season. During the 

fall of the year the flow from Grand Lake and the lower course of the East Branch 

is generally the natural flow.

Cooperation. Records are furnished by Mr. George H. Hamlin, of Orono, through 

the office of the Maine State Water Storage Commission.

PENOBSCOT EIVEB BASIN. 37

EAST BRANCH OF PENOBSCOT EIVEE AT GRINDSTONE, MAINE.

Location. Bangor & Aroostook Railroad bridge half a mile south of railroad station 

at Grindstone, one-eighth mile above Grindstone Falls, and about 8 miles above 

the mouth at Medway.

Records available. October 23, 1902, to December 31, 1912. Data also in annual 

reports Maine State Water Storage Commission.

Drainage area. 1,100 square miles.

Gage. Standard chain; datum unchanged.

Channel. Practically permanent; stream confined by abutments of bridge and 

broken by one pier at ordinary stages; velocity of current medium at moderate 

and high stages, but sluggish at low water.

Discharge measurements. Made from railroad bridge.

Winter flow. Affected by ice.

Artificial control. Several dams are maintained at the outlets of a number of lakes 

and ponds near the source of the river and regulated in the interests of log driving. 

During the summer and fall gates are generally left open. The basin of the 

East Branch since about 1840 includes about 270 square miles of additional 

territory draining into Chamberlain Lake that formerly drained into the St. John 

Elver basin. This diversion is made through what is known as the Telso canal.

Accuracy. The relation between gage height and discharge is materially affected 

by backwater from log jams that form at the station and at Grindstone Falls 

immediately below and during the winter months by ice. Besults believed to 

be fair for moderate and high stages, but uncertain for low water. 

The following discharge measurement was made by F. E. Pressey: 

March 7, 1912: Gage height, 5.64 feet; discharge, 375 second-feet. Relation of gage

height to discharge affected by ice.

Daily gage height, in feet, of East Branch ofPenobscot River at Grindstone, Maine, for 1912,

NOTE. Relation of gage height to discharge affected by ice Jan. 1 to about Apr. 18; average thickness 

of ice from 0.7 to 2.1 feet. Gage observer reported anchor ice in river on Dec. 10; river partly frozen over 

Dec. 21 and river frozen over Dec. 30. Relation of gage height to discharge may have been affected by ice 

during these periods in December, but effect is not considered sufficient to warrant correction.

NOTE. Daily discharge computed from a rating curve fairly well defined between 400 and 10,000 secondfeet. Discharge Jan. 1 to Apr. 18 estimated, because of ice, from one discharge measurement, gage heights, 

observer's notes, and climatologic records: January, 750 second-feet; February, 480 second-feet; March, 

1,000 second-feet, varying from about 350 to 1,800 second-feet; Apr. 1-18, 2,800 second-feet, varying from 

about 2.000 to 6,000 second-feet. See footnotes to table of daily gage heights relative to possible ice effect 

during December.

PENOBSCOT BIVEE BASIN. 39

MATTAWAMKEAG EIVER AT MATTAWAMKEAG, MAINE.

Location. At Maine Central Railroad bridge at the village of Mattawamkeag, half

a mile above the mouth of the river. 

Records available. August 26, 1902, to December 31, 1912. Data also in annual

reports Maine State Water Storage Commission. 

Drainage area. 1,500 square miles. 

Gage. Standard chain; datum unchanged. 

Channel. Practically permanent; broken by two bridge piers. 

Discharge measurements. Made from the bridge, which is slightly oblique to

the current; low-water measurements made by wading at a point about 1 mile

above the station. 

Winter flow. Affected by ice. 

Artificial control. Dams are maintained at the outlets of several large lakes and

ponds, but the stored water is used only for log driving. 

Accuracy. Relation between gage height and discharge is at times affected by

backwater from log jams that form during short periods in the log-driving season,

and, during the winter months, by ice. A very good open-channel discharge

rating curve has been developed.

PISOATAQUIS RIVER NEAR FOXCROFT, MAINE.

Location. At Low's highway bridge, about halfway between Guilford and Poxcroft, three-fourths of a mile above the mouth of Black Stream and 3 miles below 

Mill Stream.

Records available. August 17, 1902, to December 31,1912. Data also in annual 

report of the Maine State Water Storage Commission.
PENOBSCOT EIVEE BASIN. 41

Drainage area. 286 square miles.

Gage. Staff, attached to left abutment of bridge; datum unchanged.

Channel. Practically permanent; banks high and overflowed only during extreme 

floods.

Discharge measurements. At medium and high stages made from the bridge; 

at low stages made by wading either above or below the bridge, where the bed is 

of fine gravel but the velocity is greater than at the bridge.

Winter flow. Affected by ice during some years.

Artificial control. The stream is used to develop power at several manufacturing 

plants above the station.

Accuracy. The relation between gage height and discharge at low stages is considerably affected by the irregular use of the water at the mills; during some 

winters it is also affected by ice; little if any affected by backwater from log 

jams, as little log driving is now done on the river. A very good rating curve 

has been developed for medium stages, but the curve for high and low stages is 

not yet accurately defined.

KENDUSKEAG STREAM NEAR BANGOR, MAINE.

Location. At Mghway bridge at Sixmile Falls, about 6 miles northwest, of Bangor. 

Records available. September 15,1908, to December 31,1912. Data also in annual 

reports of Maine State Water Storage Commission.
PENOBSCOT KIVEE BASIN. 43

Drainage area. 191 square miles.

Gage. Standard chain; datum unchanged.

Channel. Practically permanent; broken by one pier; banks high and not subject 

to overflow.

Discharge measurements. Made from the bridge.

Winter flow. Affected by ice.

Artificial control. A number of years ago an artificial cut was made for log driving 

through a low divide between Souadabscook Stream and Black Stream, the latter 

a tributary to the Kenduskeag, entering about 7 miles above the gaging station. 

During high stages of the Souadabscook a portion of its waters finds its way through 

the artificial cut into the Kenduskeag; at low stages of the Souadabscook all the 

flow continues down its own channel. Black Stream probably sends its waters 

only to the Kenduskeag.

Accuracy. A good discharge rating curve has been developed, although more measurements are needed at high stages.

NOTE. Dally discharge computed from a rating curve well defined between 10 and 300 second-feet, and 

fairly well defined throughout the remainder of the range of stage during 1912.

Discharge Jan. 1 to Apr. 15 estimated, because of ice, from one discharge measurement, gage heights, 

observer's notes, climatologic records, and discharge of adjacent drainage areas: January. 250 second-feet; 

February, 150 second-feet; March, 400 second-feet, varying from about 80 to 1,000 second-feet; Apr. 1-15, 

1,000 second-feet, varying from about 700 to 1,500 second-feet.

SURFACE WATER SUPPLY, 1912, PART I. 45

KENNEBEG RIVER BASIN. 

MOOSE RIVER NEAR ROCKWOOD, MAINE.

Location. At a deserted cabin one-fourth mile above the house of Edilbert

Arsenault, 2 miles above the mouth of the river; reached by steamer or rowboat

from Kineo. 

Records available. September 1, 1902, to December 31, 1908; May 16, 1910, to

September 18, 1912. Data in annual reports of Maine State Water Storage

Commission.

Drainage area. 680 square miles. 

Gage. Standard chain; datum unchanged. 

Channel. Practically permanent. 

Discharge measurements. Made from a car suspended from a steel cable or, at

low stages, by wading at a section a short distance downstream. 

Winter now. Affected by ice. 

Artificial control. Dams are maintained at the outlets of several of the lakes above

the station, but all such stored water is used for log driving and the effect on the

regimen of flow is but temporary. 

Accuracy. The relation between gage height and discharge is at times affected

by backwater from log jams, and during the winter by ice; otherwise conditions

favor accurate determination of discharge, and a good discharge rating curve

has been developed except for extremely low stages.^

Daily gage height, infect, of Moose River near Rockwood, Maine, for 1912.

KENNEBEC KIVEE BASIN. 47

MOOSEHEAD LAKE AT EAST OUTLET, MAINE.

Location. At the wharf at the east outlet of the lake, about 8 miles from Kineo.

Records available. April 1, 1895, to December 31, 1912.

Drainage area. 1,240 square miles.

Gage. Staff, at end of boat landing; two daturas have been used at the east outlet; 

the original datum is at elevation 1,011.30 feet above mean sea level and approximately 10 feet below the sills of the outlet gates; gage is read to this datum; the 

m second, to which all gage readings published to and including 1911 have been 

referred, is 10 feet higher; that is, the zero is at the eill of the gates. It is believed 

that low water may go below the sill of the gates (zero of second datum) and so 

gage heights in this report are published as read; that is, to the original datum 

1,011.30 feet above mean sea level.

Artificial control. The lake is regulated to a capacity of 23,735,000,000 cubic feet. 

The dam at the east outlet is controlled by 35 gates; 15 old gates are at gage height 

10 feet (original datum) and 20 gates at sill-gate height 8 feet (original datum). 

At extreme low stages the flow from the lake is controlled not by the gates but 

by a bar above the dam at an approximate gage height of 9 feet (original datum). 

The records show only fluctuations in the level of the lake, and are used in the 

studies of regulation of the lake and in computing the natural flow of the Kennebec 

at The Forks station.

Storage capacity. Approximately equal to a discharge of 124 eecond-feet for one 

month (30 days) for each tenth foot of depth over the surface of Moosehead Lake.

Cooperation. Record kept and furnished for publication by the Hollingsworth & 

Whitney Co.

48 SURFACE WATER SUPPLY, 1912, PART I.

KENNEBEC RIVER AT THE FORKS, MAINE.

Location. At wooden highway bridge across river about 2,000 feet above the mouth 

of Dead River.

Records available. September 28,1901, to December 31,1912. Data also in annual 

reports of Maine State Water Storage Commission.

Drainage axea. 1,570 square miles.

Gages. Standard chain, attached to bridge, a staff gage attached to timber retaining 

wall on left bank 75 feet above the bridge, and an automatic gage installed June 

21, 1912, on the left abutment. Datum of gages unchanged.

Channel. Practically permanent; unbroken by piers.

Discharge measurements. Made from the bridge.

Winter flow. Affected by ice.

Artificial control. The flow of the Kennebec above The Forks is controlled through 

Moosehead Lake (see p. 47); Indian Pond, about 12 miles above the station, is 

under regulation for log driving from about May 1 to July 31 of each year.

Accuracy. The relation between gage height and discharge is affected by the regulation of the stream for log driving and for the extensive water-power plants below 

and, during the winter, by ice. The operation of the gates at Indian Pond Dam 

(from about May 1 to July 31 of each year) causes fluctuations in daily gage heights 

at The Forks ranging from 2 feet to more than 5 feet. A good rating curve has been 

developed for the station. The variations in gage heights have been closely 

noted, record being kept of the maximum and minimum heights for each day 

during the log-driving season, the length of time that the driving head continues, 

and the hours at which the gates at Indian Pond are opened and closed each day. 

Although set to the same datum in practically the same cross section, the automatic gage does not read the same as the chain gage above about 1.2 feet, as shown 

by the table of relation below. A careful determination of the cross section of the 

water surface at chain-gage height 5.5 feet clearly showed the transverse slope 

and checked the table of relation at that stage. It should be noted that the left 

abutment is on the concave side of a distinct bend in the river and that the chain 

gage is about 90 feet from the left abutment. A discharge rating curve referred 

to automatic gage heights was developed from the discharge rating curve referred 

to chain-gage heights by meafts of the table of gage relation. Discharge for each 

4-hour period, June 21 to December 31, was computed from this rating curve and 

the daily discharge as published is the mean of the discharge for six periods and 

therefore more accurate than the discharge obtained by entering the rating table 

with the published mean daily gage height.

NOTE. Relation of gage height to discharge affected by ice Jan. 1 to Apr. 15. Probably no material 

effect during December. Gates at Indian Pond were closed June 10. Gage heights June 10 to 20 are not 

true indices of discharge, owing to the effect of regulation for the purpose of log driving. Gage heights 

missing July 2 to 8, July 27, Aug. 16 to 20, Nov. 3, and Dec. 5, 22, and 29 because automatic gage did not 

work satisfactorily and no observations were made with chain gage. Gage heights Jan. 1 to June 9, from 

chain gage, and June 21 to Dec. 31, from automatic gage. See Accuracy in station description.

NOTE. Daily discharge determined from two well-defined discharge rating curves. (See Accuracy In 

station description.) The determinations for June 10 to 20 are approximate, however, as a result of possible 

errors in computed discharge caused by controlled flow for flushing logs down the river and backwater from 

log jams. The daily discharge for this period was computed by applying the rating table to the several 

gage readings taken during any given day. and weighting the values in accordance with the proportional 

part of the day to which each gage height is applicable. Daily discharge estimated for days when gage 

heights are missing. No correction was made for possible effect of backwater from i ce during December. 

Discharge Jan. 1 to Apr. 15 estimated, because of ice, from one discharge measurement, observer's notes, 

climatologic records, discharge of adjacent drainage areas, and storage in Moosehead Lake:

KENNEBEC KIVER AT WATERVILLE, MAINE.

Location. At the dam and mill of the Hollingsworth & Whitney Co., at Waterville, 

2 miles above the mouth of Sebasticook River and about 3J miles above the 

mouth of Messalonskee Stream.

Records available. March 22, 1892, to December 31, 1912. Data also in annual 

reports Maine State Water Storage Commission.

Drainage area. 4,270 square miles.

Gage. Rod gages in the pond above the dam and in the tailrace of the mill.

Determination of discharge. The discharge is computed from the flow over the 

dam, through the logway, and through 18 wheels of the mill. Most of the wheels 

were rated at Holyoke, Mass., under practically the same head as that used at 

Waterville about 23 feet. Methods and diagrams for estimating the flow have 

been developed by the company, and the amount lost by leakage and used for 

washing and various purposes in the mill is estimated. When; the flow of the 

river is less than about 3,500 second-feet all the water is used through the wheels.

Winter now. As la rule, not affected by ice. During most years the winter flow 

passes through the wheels of the mill.

Artificial control. Numerous power plants and much storage above the station.

Accuracy. Results are considered fair only, as many wheels are in operation and 

only one reading a day is made for each wheel, but the record is valuable because 

of its length and continuity.

Cooperation. Records are obtained and estimates of daily discharge are fruniehed 

by the Hollingsworth & Whitney Co.

Gage. Inclined staff bolted to large bowlder on the left bank, a short distance from

observer's house; datum unchanged. 

Channel. Practically permanent; banks medium high; overflowed only at extreme

high water.

Discharge measurements. Made from a car suspended from a cable a short distance above the gage. 

Winter flow. Affected by ice. 

Artificial control. A number of dams on the lakes above; used solely for log

driving. 

Accuracy. Relation between gage height and discharge affected by ice during

the winter and by the control of the stream for log driving during May and June.

Special note is made of the length and time of the drive and of the maximum

and minimum head used.

NOTE. Daily discharge computed from a rating curve well defined between 50 and 2,000 second-feet. 

Above 2,000 second-feet curve is simply an extension and estimates of daily discharge should be used with 

caution. Discharge Jan. 1 to Apr. 17, 1911, Dec. 29, 1911. to Apr. 11, 1912, and Nov. 29 to Dec. 1,1912, 

estimated, because of ice, from gage observer's notes, weeKly gage heights, climatologic records, and discharge of adjacent drainage areas: January, 1911, 100 second-feet; February, 1911, 80 second-feet; March, 

1911, 130 second-feet; Apr. 1-17, 1911. 600 second-feet; January, 1912. 170 second-feet; February, 1912, 130

NOTE. See footnotes to table of daily discharge.

SEBASTICOOK RIVER AT PITTSFIELD, MAINE.

Location. At steel highway bridge just above the Maine Central Railroad bridge 

in the town of Pittsfield.

Records available. July 27, 1908, to December 31, 1912. Data also in annual 

reports of Maine State Water Storage Commission.

Drainage area. 320 square miles.

Gage. Standard chain; datum unchanged.

Channel. Practically permanent; banks high and rocky and not subject to overflow; stream confined between the abutments of the bridge.

Discharge measurements. Made from the highway bridge.

Winter flow. Not generally affected by ice, as the rapid fall and proximity of the 

power plant immediately above the station tend to keep the river open.

Artificial control. About 800 feet upstream from the station is the dam of the 

Robert Dobson Co. and the Smith Wooden Co.; about half a mile farther upstream is the dam of the Waverly woolen mill. About 5 miles below the station 

and 2 miles from Burnham is the dam of the Sebasticook Power Co., but the fall 

of the stream prevents backwater from the lower dam.

Accuracy. The accuracy of the mean daily gage height given in the table below 

is more or less affected by fluctuations in stage caused by the operation of the 

dams above the station for night storage. Conditions favor the accurate determination of discharge, and a fair rating curve has been developed; a few more 

measurements are needed to closely determine the flow at extreme high and 

extreme low stages.

COBBOSSEECONTEE STEEAM AT GAEDINEE, MAINE.

Location. At the dam of the Gardiner Water Power Co., in the city of Gardiner.

Records available. June 16, 1890, to December 31, 1912.

Drainage area. 220 square miles. Measured on recently completed topographic 

sheets. Value given in previous reports about 10 per cent too large. See Accuracy.

Gages. One in pond above dam and one in tailrace of power house.

Determination of flow. The discharge is determined by considering (1) the flow 

over the dam, usually nothing except for a short time in the spring; (2) the flow 

through two gates; and (3) the flow through a 39-inch Hercules wheel. The computations of daily discharge are made by the engineers of the S. D. Warren Co. 

from tables of discharge based on careful experiments.

Winter flow. Not affected by ice.

Artificial control. The extensive lakes in the basin are controlled by storage dams 

and the stream affords a remarkable example of the regularity of flow that can 

be obtained with proper storage. Except for a short time in the spring no water 

is wasted.

Accuracy. Results are considered good for a station of this type. Run-off per square 

mile and depth in inches on drainage area, as published in earlier reports, should 

be recomputed by means of new value for drainage area.

Cooperation. Station maintained by the S. D. Warren Co., which furnished the 

records of daily discharge for publication.

Daily discharge, in second-feet, of Cobbosseecontee Stream at Gardiner, Maine, for 1912.

ANDBOSCOGGIN RIVER BASIN. 

ANDBOSCOGGIN BIVEB AT EEEOL BAM, N. H.

Location. Errol dam, 1 mile above the town of Errol, N. H.

Records available. January 1, 1905, to December 31, 1912. Data also in annual

reports Maine State Water Storage Commission. 

Drainage area. 1,095 square miles. 

Gage. Movable rod gage; readings taken each day from the sill of deep gate No. 6;

elevation of zero of gage or sill of gate is 1,231.3 feet above mean sea level.
AFDBOSCOGGIF RIVER BASIN. 61

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

coefficients determined from a few discharge measurements.

The dam is a wooden structure completely housed over, about 175 feet between 

abutments. Extensive repairs were made on the dam during November and 

December, 1912. The entire flow passes through gates of different sizes, 14 in all. 

There is no provision for overflow besides the gates. Beginning at the left end, 

the gates are as follows:

One gate 10 feet deep by 15 feet wide, seldom used; three gates 10J feet deep 

by 15 feet wide, open most of the time; nine gates 15 feet deep by 7 feet wide in 

the clear (so-called deep gates), open a portion of the time only; one gate 15 feet 

deep by 5 feet wide, gristmill gate and used only occasionally. The cap of all the 

14 gates is one continuous beam and on the same level, thus mfrlHTig the bottom 

of the various gates at different levels.

A "deadhead" of 2.66 feet exists a short distance above the present dam, this 

point at present controlling the low flow.

The depth on the deep gates does not indicate the true height of water in Umbagog Lake on account of this "deadhead " formed by the old dam and by the bar at 

"Quick Water Point," the lowest point of which is about 4 feet above the sill of 

the present dam.

Winter flow. Little affected by ice.

Artificial control. Errol dam controls the storage of Umbagog Lake, the lower of 

the Rangeley series of lakes, comprising the principal storage of the Androscoggin 

River and amounting to about 19 billion cubic feet, and also a recently developed 

storage site on Magalloway River created by the Azicohos dam, which amounts 

to about 8 billion cubic feet, thus making the total storage about 28 billion cubic 

feet. Errol dam is located about 5 miles below the outlet of Umbagog Lake and 

about 3.5 miles below the mouth of Magalloway River, thus making this latter 

stream one of the feeders of Umbagog Lake.

Accuracy. The discharge is derived from coefficients applied to the various gate 

openings as determined from a number of current meter gagings. The ratings, 

however, are not as thorough as could be desired, and the results are considered 

very roughly approximate.

Cooperation. Records are obtained and computations of daily discharge made 

under the direction of Mr. Walter H. Sawyer, agent for Union Water Power Co., 

who furnished data to the survey.

Daily discharge, in second-feet, of Androscoggin River at Errol dam, N. H.,for 1912.

a Estimated from probable discharge at the Ponticook dam (about 18 miles below), which is used as a 

regulating dam for the mills of Berlin, N. H.

ANDROSCOGGIN RIVER AT RUMFORD FALLS, MAINE.

Location. Dam of the Rumford Falls Power Co., at Rumford Falls.

Records available. May 18, 1892, to December 31, 1912. Data also in annual 

reports Maine State Water Storage Commission.

Drainage area. 2,090 square miles.

Gage. One located in pond above dam and one in tailrace of power house.

Discharge. Computed from discharge over the dam, using the customary Francis 

weir formula with modified coefficient, and the quantities passing through the 

various wheels of the power house, which have been thoroughly rated.

Winter flow. Little affected by ice.

Artificial control. The storage in the Rangeley system of lakes at the headwaters 

of Androscoggin River, aggregating 28,000,000,000 cubic feet, is largely under 

complete control. The stored water is regulated in the interests of the waterpower users below and is under such excellent management that this is one of 

the best water-power streams in the country.

Accuracy. Results are believed to be excellent.

Cooperation. Records are obtained and computations made by Mr. Charles A. 

Mixer, engineer Rumford Falls Power Co., who furnishes the data through the 

district office.

64 SURFACE WATER SUPPLY, 1912, PART I.

PRESTJMPSCOT RIVER BASIN. 

PRESUMPSCOT RIVER AT OUTLET OF SEBAGO LAKE, MAINE.

Location. Outlet dam at Sebago Lake and the hydroelectric plant at Eel Weir 

Falls, 1 mile below lake outlet.

Records available. January 1, 1887, to December 31, 1912. Data also in annual 

reports Maine State Water Storage Commission, in the second of which reports 

are published results of a recomputation of all data from 1887 to 1911.

Drainage area. 436 square miles.

Gages. On the bulkhead of the gatehouse at the outlet dam and in the fore bay 

and tailrace of the power plant.

Discharge. Prior to March, 1904, the discharge was deduced from the records of 

the opening of the gates in the dam, the discharge capacity of which under different conditions of head has been determined and tabulated by Mr. Hiram F. Mills, 

of Lowell.

In March, 1904, a hydroelectric plant was completed at Eel Weir Falls, the 

water being brought directly from the outlet dam to the plant by means of a 

canal about a mile long. This new plant has necessitated a different method of 

recording the flow from the lake. The water passes through three pairs of 30-inch 

Hercules wheels, the amount being recorded by three Alien meters, one on each 

pair. These meters were rated by the result of a test at Holyoke, Mass., of one 

pair of wheels. Since the station was finished the performance of the wheels and 

of the recording meters has been checked by current-meter measurements, brake 

tests of the wheels, and electrical readings of the generator output. It is usually 

desired to keep a constant flow through the canal, and when demands for power 

are not sufficient to utilize the entire flow through the wheels, the excess of 

water is run off through a pair of regulating gates at the power station. A record 

of the opening of these gates is kept and the flow computed from a coefficient 

determined from current-meter tests.

At times the flow from the lake may be greater than is safe to carry through the 

canal, though this has not yet happened. At such times it will be necessary to 

draw a part of the water through the old regulating gates in the main dam.

Winter flow. No trouble from ice.

Artificial control. Sebago Lake, with an area of 46 square miles, is under complete control for storage. It is a magnificent natural storage reservoir and its 

utilization for this purpose has made the flow of the Presumpscot extremely 

regular.

Accuracy. Results very good for a station of this type.

Cooperation. Records obtained and computations of daily discharge made and 

furnished by the S. D. Warren Co.

Daily discharge, in second-feet, of Presumpscot River at outlet of Sebago Ldket Maine,

for 1912.

SACO RIVER BASIN.

SACO EIVEE NEAE CENTEE CONWAY, N. H. 

Location. At the wooden highway bridge between Center Conway and Redstone,

N. H., about 2 miles from each place, about 3 miles below the mouth of Swift

River, and 2 miles above the outlet of Conway Lake. 

Records available. August 26, 1903, to June 30, 1912. Data also in annual reports

of the Maine State Water Storage Commission. 

Drainage area. 385 square miles. 

Gage. Chain attached to bridge; datum unchanged. 

Channel. Recent measurements indicate radical changes in conditions of flow; but

insufficient measurements have been taken to define the new discharge rating

curve. Channel broken by one pier.

Discharge measurements. Made from the bridge or by wading. 

Winter flow. So affected by ice that gage-height observations are discontinued.

SAGO RIVER AT WEST BUXTON, MAINE.

Location. At hydroelectric plant of the Portland Electric Co. at West Buxton, Maine. 

Records available. October 19, 1907, to December 31, 1912. Data also in annual

reports Maine State Water Storage Commission. 

Drainage area. 1,550 square miles.

Gages. One in pond above dam and one in tailrace of power house. 

Channel. Crest of the concrete dam, about 300 feet long. 

Discharge. The flow over the dam and through the rated wheels of the power

plant is determined by means of gage readings taken every hour. 

Winter flow. No trouble from ice. 

Artificial control. There are dams on numerous although comparatively small

lakes in the basin above the station. Regulation of storage probably has some

effect on the regimen of the stream but not to the extent that obtains in the other

basins in the State of Maine, where natural storage facilities are better and more

fully developed.

Accuracy. Results believed to be good for a station of this type. 

Cooperation. Records obtained and computations of daily discharge made and

furnished by the Cumberland County Power & Light Co.

Daily discharge, in second-feet, ofSaco River at West Buxton, Maine, for 1912.

JMERRIMAC RIVER BASIN. 

MIDDLE BRANCH OP PBMIGEWASSBT RIVER AT NORTH WOODSTOCK, N. H.

Location. At a dam about half a mile upstream from the North Woodstock post 

office.

Records available. September 18, 1911, to October 31, 1912.

Drainage area. 28.6 square miles.

Gage. Vertical staff, attached to wall of forebay, near the racks; an automatic gage 

was eet on a shelf over the forebay April 4 to October 31,1912.

Channel. Gage heights at thie station indicate the head on the crest of the spillway 

at the dam. The spillway is 110.85 feet long and has an ogee section. The 

crest is comparatively level, having a mean gage height of 0.1 foot. The dam is 

constructed for the installation of two wheels, neither of which has yet been 

put in. There is no leakage through the dam or through the unfinished penstocks.

Discharge measurements. Made by wading below the dam.

Winter flow. The crest of the dam was cleared of ice before the gage heights were 

obtained, so that open water prevailed for the entire period of the record.

Accuracy. Estimates for the extreme low flow at this station are good. No measurements were made at the high stages to check up a coefficient for the spillway.

Cooperation. Maintained in cooperation with the Department of Agriculture in 

connection with the intensive studies for the acquisition of lands for the protection of watersheds of navigable streams.

N. H., in 1912.

NOTE. Discharge for periods for which gage records are missing determined by interpolation and by 

use of climatologic data.

PEMIGEWASSET RIVER AT PLYMOUTH, N. H.

Location. In the town of Plymouth, about 40 feet above the covered wooden highway bridge three-fourths of a mile below the mouth of Bakers River.

Records available. 1886 to December 31, 1912.

Drainage area. 615 square miles.

Gages. Two gages have been maintained at this station. From September 4,1903, 

to June 30, 1907, readings were taken with the chain gage established by the 

"United States Geological Survey on the upstream side of the bridge; the datum 

of this gage has remained the same during the maintenance of the station. Since 

June 30, 1907^ gage heights have been furnished by the Locks & Canals Co., 

of Lowell, Mass., from readings taken on the staff gage, the low and medium 

stage sections of which are about 40 feet above the bridge and on the same side of 

the river as the chain gage. The high-stage section is bolted to the upstream side 

of the right abutment; the datum of this gage is 1.11 feet higher than that of the 

chain gage. All gage readings prior to 1910 were reduced to chain-gage datum. 

At low stages the difference in readings between the two gages is 1.11 feet; at 8.1 

feet on the staff gage the difference is 0.99 feet. Owing to the slight difference 

in the relation of stage to discharge at the locations of the two gages and to the 

fact that gage readings are now taken on the staff gage, it is considered advisable 

to publish all gage heights beginning with 1910 exactly as received from the 

Locks & Canals Co., namely, as referred to the staff-gage datum.

Channel. Eocky and probably fairly permanent in the right channel; fine gravel, 

shifting occasionally at times of high floods, in the left channel.

Discharge measurements. Made from the bridge at ordinary and high stages. 

At low. stages the right channel is measured from the bridge and the left channel 

by wading.

Artificial control. The nearest dam upstream is at the pulp mills at Livermore 

Falls, 3 miles above; downstream the nearest dam is at Franklin, 25 miles distant. 

The control of the flow at Livermore Falls and also at the dam at Woodstock, 17 

miles upstream, affects the low-water discharge slightly.
MEREIMAC EIVEB BASIN. 71

Winter flow. Affected by ice, which forms on the control about 300 feet below the 

bridge. Discharge from sewer entering a short distance above the gage usually 

keeps the river open on right bank near the staff gage.

Accuracy. Estimates of discharge covering the period from 1886-1903 were made and 

published in Water-Supply Paper 124, pages 97-101. At the time these estimates 

were published it was believed that conditions of flow were stable, but two quite 

radical changes have since occurred, one in 1905 and one in 1910, the discharge 

at a stage of 1.2 feet (chain gage) having varied as follows: 1904, discharge 110 

second-feet; 1905, discharge 158 second-feet; 1910, discharge 213 second-feet. 

Hence, these earlier estimates of discharge should be used with caution for low 

stages, although they are probably essentially correct for medium and high 

stages. For the period since 1903 good discharge rating curves have been developed. Conditions for obtaining accurate discharge data are good, except at low 

stages, when the control of the flow at Livermore Falls affects the accuracy of 

the computed values of daily discharge.

Cooperation. Gage heights since June 30, 1907, furnished by the Locks & Canala 

Co., of Lowell, Mass.

NOTE. Daily discharge Jan. 27 to Mar. 13, inclusive, computed by correcting gage heights according to 

the amount of backwater from ice indicated by discharge measurements made during that period; this 

effect is so consistent that the discharge values should be good. Discharge interpolated for days on which 

gage was not read.

MERRIMAC RIVEE BASIN. 73

MERRIMAC RIVEK AT FRANKLIN JUNCTION, N. H.

Location. At covered wooden bridge of the Boston & Maine Railroad near Franklin 

Junction, N. H., about 1 mile below the confluence of PemigewaBset and Winnepeeaukee rivers.

Records available. July 8,1903, to December 31, 1912.

Drainage area. 1,460 square miles.

Gage. Standard chain fastened to floor of bridge on upstream side over the righthand channel. A gage painted on the downstream right-hand Bide of the center 

pier is used by the United States Weather Bureau for high-water readings.

Channel. Coarse gravel and bowlders; fairly permanent.

Discharge measurements. Made from upstream side of the bridge.

Winter flow. Ice usually affects the relation between gage height and discharge 

for short periods during the winter months.

Artificial control. Several dams above the station on both Pemigewasset and 

Winnepesaukee rivers affect the discharge. The operation of the mills above 

the station causes more or less fluctuation in stage each working day. It is not 

known how much this affects the reliability of the records. Winnepesaukee, 

Squam, and New Found lakes also offer opportunities for storage and are under 

more or less regulation.

Accuracy. During open-water periods the results are believed to be fairly good.

Cooperation. All of the data published by the United States Geological Survey 

are based on chain gage readings which have been furnished by the Locks & 

Canals Co., of Lowell, Mass., since June 30, 1907. 

No discharge measurements were made during 1912.

made during 1912 to verify this curve. Discharge Oct. 25 to 28, inclusive, estimated by comparison with 

records of Pemigewasset River at Plymouth, N. H., assuming a constant rate of flow during this period 

from Lake Winnepesaukee. Discharge interpolated for other days on which gage was not read.

MERRIMAC RIVER BASIN. 75

MEEEIMAC RIVER AT GARVINS FALLS, N. H.

Location. At the dam of the Manchester Traction, Light & Power Co., 4 miles 

below Concord, N. H. The Garvins Falls plant is one of a system including 

three water-power plants and one steam-power plant operated by this company. 

The Garvins Falls site, one of the best on Merrimac River, has been utilized 

since 1815, first in connection with Old Bow Canal and later to furnish power for 

a pulp mill.

Records available. 1904 to 1912.

Drainage area. 2,340 square miles.

Dam. During 1903^4 an overfall dam of the ogee type, somewhat similar in cross 

section to the dam at Holyoke, was completed. This dam is 550 feet long between 

abutments, and about 800 feet over all, including the head gates, and is'of stone 

masonry, substantially built. The new dam and head gated are situated about 

800 feet downstream from the old dam, which was destroyed on the completion 

of the new structure.

Canal and wasteways. A canal has been completed which is about 500 feet long 

and 74 feet wide at the water line; in the sides of this canal wasteways are provided, one 90 feet long at elevation 102 feet (the main crest of the dam being taken 

as elevation 100) and another 45 feet long at elevation 103 feet. A waste gate, 

10 feet wide and capable of being lowered to elevation 93 feet, is also provided 

for use in floating out any obstructions which lodge against the racks.

Turbines. There are six triplex turbines, of somewhat more than 1,000 horsepower 

each, and one small duplex turbine of 75 horsepower used in running exciters; 

each large unit has three 39-inch runners mounted on a horizontal shaft which 

revolves at 180 revolutions a minute. Two of the wheels in each set discharge 

through a common T center and draft tube near the forebay wall. The third 

wheel is set opposite a quarter turn at the downstream end of the casing and 

discharges through this quarter turn into a smaller draft tube. The top of the 

penstock opening is at elevation 95.5; the lower ends of the draft tubes are 

horizontal and are about 2 feet below the elevation of usual tail water. The 

gates for the runners are of the plain cylindrical pattern, without fingera, and 

are controlled by governors. The average head on the wheels is about 29 feet, 

and there are six 650-Mlowatt 3-phase generators directly connected with the 

turbines.

Utilization of power. The power developed ia transmitted at 12,000 volts tension 

to Manchester, about 14 miles away, where it enters a substation and is transformed to a lower voltage and utilized through a distributing switchboard for 

light and power.

Computations of discharge. Careful records of the pond and tailrace levels, 

wheel openings, etc., have been kept by the company since completion of the 

dam in 1904 and have been furnished for computations of flow by J. Brodie Smith, 

manager. A number of current-meter measurements have been made from time 

to time by engineers of the United States Geological Survey for the purpose of 

rating turbines and to assist in computing the flow over the dam.

Winter flow. The flow over the dam is somewhat affected by ice during the winter.

Accuracy. Conditions at this station favor accurate determinations of discharge.

Cooperation. Records furnished for publication by Hollis French and Alien 

Hubbard.

MERRIMAC RIVER AT LAWRENCE, MASS.

Location. At the dam of the Essex Water Power Co. in Lawrence.

Records available. 1890-1912.

Diversions. Water is diverted from the drainage basins of Sudbury and Nashua 

rivers for use by the Metropolitan district in the vicinity of Boston, but during 

a portion of the year water is wasted into the Merrimac at these diversion dams; 

consequently the drainage area is somewhat variable.

' Computations of discharge. Careful record is kept of the flow over the dam and 

through the various wheels and gates in connection with the sale of power, and 

the quantity measured at Lawrence includes the water wasted into the Merrimac 

from the Sudbury, Nashua, and Cochituate drainage basins. In getting the 

absolute yield of the river this fact should be considered in reference to the 

drainage areas, either by deducting it from the Merrimac flow and using the net 

area and the net flow of the Merrimac, or by getting the total yield of both Sudbury and Nashua rivers with the Merrimac and using the total area. The estimate 

of the quantity wasted from Sudbury and Nashua drainage basins into the Merrimac 

is based on data furnished by the Metropolitan Water and Sewerage Board of Boston. 

Accuracy. Such care is taken in procuring the base data used and in making computations that the records are regarded as excellent.

Cooperation. Records furnished for publication by R. A. Hale, principal assistant 

engineer of the Essex Water Power Co.

SOUHEGAN RIVER AT MERRIMAC, N. H.

Location. Just above Atherton Falls, about 1| milea above the dam of the W. H. 

McElwain Co., below the mouth of Stony Branch, and just above the junction of 

the Souhegan with the Merrimac.
MERRIMAC EIVER BASIN. 79

Records available. July 13, 1909, to December 3i; 1912.

Drainage area. 168 square miles.

Gages. Vertical staff on the left bank 40 feet above the falls, used until April 11, 

1911, when it was washed, out. On April 12, 1911, a chain gage was attached to 

a tree about 300 feet upstream from the staff gage. Both gages refer to the same 

datum.

Channel. One at all stages. Not liable to shift.

Discharge measurements. At high stages from bridges above and below the station; at low stages by wading at a section below the gage.

Artificial control. Flow affected by the operation of mills at Milford, about 8 to 

10 miles above, which causes a few hundredths of a foot difference between the 

morning and afternoon readings. In determining the daily discharge, it is 

assumed that the average of these readings gives essentially the true 24-hour 

mean. No information is available regarding night storage at Milford.

Winter flow. Relation of gage height to discharge is not greatly affected by ice.

Accuracy. Discharge rating curve quite well developed.

Cooperation. Established and maintained in cooperation with the W. H. McElwain 

Co.

SOUTH BRANCH OF NASHUA RIVER, (WACHUSETT DRAINAGE AREA) AT

CLINTON, MASS.

Location. At Clinton, Mass.

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

Drainage area. 118.19 square miles.

Computations of discharge. A large reservoir, storing about 8,500,000,000 cubic 

feet, was constructed at Clinton, Mass., and has stored water since 1903. Beginning with 1897 the estimates of discharge have been corrected for gain and loss 

of storage in reservoirs and mill ponds, so that the results show the natural flow 

of the stream.

The yield reported per square mile is the yield of the drainage area, including 

the water surfaces. In the Wachusett basin this water surface for the years 

1897 to 1902, inclusive, amounted to 2.2 per cent of the whole area; in 1903, 2.4
MERBIMAC RIVER BASIN. 81

per cent; in 1904, 3.6 per cent; in 1905, 4.1 per cent; in 1906, 5.1 per cent; in 1907, 

6.0 per cent; and in 1908 and subsequent years, 7.0 per cent.

The accompanying tables give data on discharge and precipitation for 1912? 

also the average for the years 1897-1912, inclusive, precipitation averages being 

based on records at several stations in the Nashua drainage basin.

SUDBURY RIVER AT FRAMINGHAM AND LAKE COCHITUATE AT 

COCHITUATE, MASS.

Location. On Sudbury River at Framingham and on Lake Cochituate at Cochituate.

Records available. Sudbury River and Lake Cochituate have been studied by the 

engineers of the city of Boston, the State Board of Health of Massachusetts, and 

the Metropolitan Water and Sewerage Board; records of rainfall have been kept 

in the Sudbury basin since 1875 and in the Cochituate basin since 1852, but the 

latter are considered of doubtful accuracy previous to 1872.

Storage reservoirs. Storage reservoirs have been constructed by the city of Boston 

and the Metropolitan Water and Sewerage Board controlling the greater part of the 

flow from these basins. Lake Cochituate, which drains into Sudbury River a 

short distance below Framingham, is controlled as a storage reservoir by the 

Metropolitan Waterworks. In the Sudbury River basin the water surfaces 

exposed by evaporation have been increased from time to time by the construction of additional storage reservoirs. From 1875 to 1878, inclusive, the 

water surface amounted to 1.9 per cent of the total area; from 1879 to 1884, to 

3.0 per cent; 1885 to 1893, to 3.4 per cent; 1894 to 1897, to 3.9 per cent; 1898 and 

subsequent yeara, 6.5 per cent.

82 SURFACE WATER SUPPLY, 1912, PART I.

Determinations of discharge. The recorded yields of both the Sudbury and 

Cochituate drainage areas are somewhat affected by the fact that the towns of 

Framingham, Natick, and Weetboro draw public water supplies from within the 

basins and discharge the sewerage outside. Although the quantities diverted 

are taken into consideration in determining the run-off, the results are probably 

less accurate since the sewerage diversion works were constructed. 

The public water and sewerage works were installed in these towns as follows:

Water

1885

1874

1879

Sewerage 

works.

1889

1896

1892

All the water drawn from the Wachusett drainage area is passed through the 

reservoirs in the Sudbury basin, and as the measurement of these quantities must 

be used in determining the yield of the Sudbury basin, the unavoidable email 

percentages of error in the measurement of large quantities of water render less 

accurate the figures giving yields of the Sudbury water supply during months of 

low yield for years subsequent to 1897.

Cooperation. Data furnished for publication by the Metropolitan Water and 

Sewerage Board, Dexter Brackett, chief engineer.

BLACKSTONE RIVER BASIN. 

BRANCH RIVER AT BRANCH VILLAGE, R. I.

Location. At Branch Village, just below the mill of James Pitts & Son, threequarters of a mile from Forestdale and about 2 miles from Woonsocket.

Becords available. September 2, 1909, to December 31, 1912.

Drainage area. 93 square miles.

Gages. Staff, bolted to a ledge about 500 feet below the dam and mill; also a chain 

gage attached to a tree on top of the ledge. Gage heights referred to the staff gageChannel. Fairly favorable for accurate measurements.

Discharge measurements. At low and medium stagea made by wading; at high 

stages from the bridge above the dam or from a boat.

Artificial control. Gage heights are affected by the mill control directly above the 

station and also by one farther up the river. The available storage above the 

Pitts Mill is small, and water passes over the dam much of the time.

Winter flow. Relation between the gage heights and discharge affected by ice only 

in severe weather.

Accuracy. Accurate computation of the diurnal fluctuation of discharge caused by 

the operation of the mills above the station has been rendered impossible by 

insufficient funds.

Cooperation. Established and maintained in cooperation with the Natural Resources Survey of the State of Rhode Island. Gage heights furnished by Jamea 

Pitts & Son.

SURFACE WATEK SUPPLY, 1912, PART I. 85

CONNECTICUT RIVER BASIN. 

CONNECTICUT RIVER AT ORFORD, N. H.

Location. At covered highway bridge between Orford, N. H., and Fairlee, Vt. 

Approximately 10 miles downstream (by river) from the mouth of Waits River.

Records available. August 6, 1900, to December 31, 1912.

Drainage area. 3,300 square miles.

Gage. Chain attached to the bridge; read once daily, datum unchanged.

Channel. Wide and deep; gravelly bottom; subject to change.

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

working through the open space near roof.

Artificial control. There are numerous power plants on the tributaries of the Connecticut River and also on the main stream above the station which may have a 

slight effect on the variation of the daily discharge. The nearest dam downstream is at Wilder, 18 miles below the station. Backwater from this dam is 

believed to reach within a few miles of Orford.

Winter flow. The relation of daily gage height to discharge is affected by ice during 

the winter months, usually from the first part of December to the last part of 

March, and sometimes well into April.

Accuracy. Discharge rating curve fairly well defined. Open-water estimates considered fairly good. The upper part of the rating curve is defined by measurements made by the vertical velocity curve method and is considered stable. 

Frequent changes in the lower part of the curve have been necessitated during 

recent years by changes in the relation of gage height to discharge. Numerous 

measurements made under ice cover have defined fairly good rating curves for 

use in the periods during which ice existed. Owing to the smooth ice cover 

which forms at this station each year and the freedom from ice jams or needle 

ice, curves developed in earlier years are considered fairly good indexes of discharge in later years.

Cooperation. Station maintained in cooperation with several New England power 

companies.

NOTE. Discharge Jan. 7 to Apr. 7, estimated from one discharge measurement, climatologic data and 

comparison records at Sunderland, Mass.

CONNECTICUT RIVER AT SUNDERLAND, MASS.

Location. At the five-span steel highway bridge at Sunderland, Mass., on the road 

leading to South Deerfield, about 18 miles in a direct line and about 26 miles by 

river above the dam at Holyoke. Deerfield River enters the Connecticut from 

the west about 8 to 10 miles above the station.

Records available. March 31, 1904, to December 31, 1912. From 1880 to 1899 a 

record of the discharge of this stream was maintained at Holyoke, Mass.

Drainage area. 7,700 square miles.

Gage. Chain gage attached to highway bridge; read twice daily.

Channel. Deep; coarse gravel; subject to change.

Discharge measurements. Made from highway bridge..

Artificial control. The first dam is about 12 miles above the station at Turners 

Falls, Mass.; the next about 29 miles above, near Hinsdale, N. H. There are 

others farther upstream and also on Deerfield, Millers, and other tributaries that 

operate to affect, more or less, the normal flow of the stream.

Winter flow. During portions of December and up to early March relation of gage 

height to discharge is considerably affected by ice.

Accuracy. Discharge rating curve fairly well defined; open-water estimates considered good.

Cooperation. Station maintained in cooperation with several New England power 

companies.

Discharge measurements of Connecticut River at Sunderland, Mass., in 1912.

NOTE. Discharge Jan. 11 to Mar. 19, inclusive, estimated from two discharge measurements, climatologlc 

data and comparison with records at Orford, N. H.

PASSTJMPSIC EIVEE NEAR ST. JOHNSBUEY, VT.

Location. At suspension footbridge just below dam of Pierce's mills, about 5 miles 

above St. Johnsbury, 2 miles below the mouth of Sheldon Branch, 4 miles above 

the mouth of Moose River, and 5 miles above the mouth of Sleepers River.

Records available. May 26,1909, to December 31,1912. A station was established 

June 29,1903, on Passumpsic River at St. Johnsbury Center, but was discontinued 

November 30 of the same year because of backwater from the dam at St. Johnsbury.

Drainage area. 237 square miles.

Gage. Staff, in two sections; low-water section a vertical staff bolted to ledge just 

above bridge; high-water section an inclined staff bolted to ledge just below 

bridge.

Channel. Semipermanent; bed composed chiefly of gravel, but near right bank 

consists of a rock ledge.

Discharge measurements. At high stages made from downstream side of bridge; 

at low stages, by wading 200 feet below.

Winter flow. River freezes over under the bridge and at control point 300 feet 

below; relation of gage height to discharge is therefore affected by ice.

Artificial control. Discharge affected by the operation of Pierc'e's mills, just above 

station, and by other mills farther upstream. The storage at Pierce's mills is small 

and the use of water nearly uniform during the day and night, so that the daily 

gage readings are fairly accurate indices of the daily discharge.

Accuracy. The discharge rating curve is well denned.

WHITE RIVER NEAR SHARON, VT.

Location. About 1,500 feet below the dam of the Vermont Copper Co., near Sharon, 

Vt., and about 800 feet above the Central Vermont Railway bridge.

Becords available. May 13, 1909, to December 31, 1912.

Drainage area. 686 square miles.

Gage. An inclined staff reading to 10 feet, attached to a large rock on the left bank. 

A chain gage for use at high stages is nailed to trees about 80 feet upstream from 

the .staff gage.

Channel. Divided by an island above the gages.

Discharge measurements. Formerly made from two suspension bridges which 

connect the island with the banks. These bridges were washed out in 1911 and 

were not replaced.

Artificial control. There are several power plants above the station, but it was 

assumed that fluctuations in daily stage caused by operation of these plants was 

sufficiently equalized at the dam of the Vermont Copper Co., until 1912, when 

the power plant was put into operation.

Winter flow. Affected by ice.

Accuracy. A fairly good rating curve has been established for thia station, so that 

the accuracy of the computed discharge depends entirely on the accuracy of 

mean daily gage heights. The published gage heights do not represent the 

mean, as the gage was read but once a day, and the discharge figures represent 

the flow only at the tune the gage was read.

NOTE. Relation of gage height to discharge affected by ice Jan,

_. 12 to Mar. 28. Daily discharge obtained 

the staff gage below the dam. See "Accu-
CONNECTICUT EIVEE BASIN. 93

DEERFIELD RIVER AT HOOSAC TUNNEL, MASS.

Location. At wooden highway bridge near Hoosac Tunnel railroad station, about 

4J miles below the mouth of Dunbar Brook, 4 miles above Pelham Brook, and 

4 miles above Cold Brook.

Records available. August 8, 1909, to December 31, 1912. A measurement was 

made at the bridge October 29, 1906.

Drainage area. 257 square miles.

Gage. Chain, fastened to left-hand downstream side of bridge; datum unchanged.

Channel. Permanent. The bed is of coarse gravel and is very rough.

Discharge measurements. At high stages made from upstream side of highway 

bridge; at low stages by wading.

Winter flow. Relation of gage height to discharge is affected by ice, as the river 

freezes completely over.

Artificial control. The operation of numerous mills on the main river and its 

tributaries above the station completely controls the flow of the river except at 

high stages and causes considerable fluctuations in gage heights during the day. 

The nearest mill is at Monroe Bridge about 7 miles upstream. For this reason it 

is not advisable to attempt to estimate the mean daily discharge from semidaily 

gage readings. The gage reader's observations are being published, together 

with the rate of flow corresponding to each.

Records available. June 1, 1907, to December 31, 1912.

Drainage area. 501 square miles.

Dam and power plant. The dam is of concrete, of ogee section, and is similar in 

form to one that has been rated. The height of the dam was increased 3 feet in 

the fall of 1908. Two units are now installed. Ratings of one of these units have 

been made by the Survey for use in conjunction with the Holyoke ratings of the 

wheels.

Computations of discharge. The flow through the wheels is computed from the 

gate openings and from power readings made at half-hour intervals. The height 

of water on the dam, in the fore bay, in the tailrace, and at the wasteways is read 

three times daily. The total electrical output is measured twice a day.

Accuracy. Owing to the extreme care with which the readings are made, winter 

and summer, the records at this station are considered good, particularly so since 

the dam was raised in 1908.

Cooperation. Records furnished by H. K. Barrows, Boston, Mass.

Daily discharge, in second-feet, of Deerfield River at Shelburne Falls, Mass., for 1912.

WARE RIVER AT GIBBS CROSSING, MASS.

Location. Between the highway bridge and the electric railway bridge, about 3 

miles below Ware, at the point known as Gibbs Crossing. Muddy Brook (drainage 

area, about 30 square miles) enters from the right at Ware; Beaver Brook (drainage area of about 29 square miles) enters from the right about 2£ miles below the 

station.

Records available. August 20 to December 31, 1912.

Drainage area. 201 square miles.

Gage. Automatic gage, protected by a wooden shelter 5 feet square, on the right 

bank just above the highway bridge, is set over a plank well 30 by 40 inches, 

the well being connected with the stream by a 4-inch cast-iron pipe. A sloping 

staff gage is set in the bank almost over the intake pipe to serve as a check on the 

automatic gage.

Channel. Rough but practically permanent.

Discharge measurements. Made from the downstream side of the highway 

bridge at extreme high stages, from the upstream side of the electric railway 

bridge at medium stages, and by wading at low stages.

Winter flow. Relation between gage height and discharge somewhat affected by 

ice during the coldest weather.

Artificial control. The operation of mills at points upstream causes a large diurnal 

fluctuation at this station and makes automatic records necessary.

Accuracy. The rating curve is well defined and estimates based on continuous 

records of gage height are good.

SWIFT EIVEE NEAE WEST WAEE, MASS.

Location. Just below the wooden dam opposite the West Ware station of the Athol 

branch of the Boston & Albany Railroad, about 6 miles by river downstream 

from Enfield.

Records available .-^July 15, 1910, to December 31, 1912.

Drainage area. 191 square miles.

Gages. Standard chain gage attached to downstream side of footbridge, about 400 

feet below the dam; in use July 15, 1910, to August 25, 1912; staff gage fastened 

to the headworks of the flume; and an automatic gage (used August 25 to December 

31, 1912) on the left bank, about 600 feet below the dam. The automatic gage is 

protected by a wooden shelter 5 feet square, and set over a timber well 3 feet 

square. The well is far enough back from the bank to protect it from the frost and 

is connected with the river by a 4-inch cast-iron pipe.

Discharge measurements. Made from cable 50 feet above the automatic gage 

during high and medium stages and by wading at low stages.

Artificial control. Mills and power plants above the station cause a very marked 

diurnal fluctuation in the flow at this point. For this reason it is not advisable 

to attempt to estimate the daily discharge from semidaily gage readings at present. Therefore the gage reader's observations prior to the installation of the 

automatic gage are being published, together with the flow corresponding to 

each.

Accuracy. A fairly good rating curve has been developed for this station and estimates based on continuous records of gage height are good.

QUABOAG BIVEE AT WEST BEIMFIELD, MASS.

Location. At the highway bridge near the West Brimfield station on the Boston & 

Albany Railroad.

Records available. August 23, 1909, to December 31, 1912.

Drainage area. 150 square miles.

Gages. Staff, attached to the upstream side of the right abutment of the bridge; 

read twice daily, August 23, 1909, to August 19, 1912. An automatic gage 

is set over a well just behind the center pier of the bridge. The automatic 

gage is sheltered by a wooden house 5 feet square over a timber well about 

3 feet square/ A staff gage on the outside of the gage well serves as a check 

on the automatic gage. The automatic gage and the original staff gage have 

the same datum and read the same at low stages. At high stages a perceptible 

slope in the river causes the automatic gage heights to read slightly lower than 

observations on the original staff.

Discharge measurements. Made from the bridge during high stages and by 

wading near the bridge at low stages.

Winter flow. Affected by ice.
110 SURFACE WATER SUPPLY, 1912, PART I.

Artificial control. Mills above the station cause,a very decided diurnal fluctuation 

in the discharge at this point. For this reason it is not advisable to attempt to 

estimate the daily discharge from semidaily gage readings at present. Therefore the gage reader's observations prior to the installation of the automatic gage 

are being published together with the flow corresponding to each.

Accuracy. A good rating curve has been developed for this station, and estimates 

based on continuous records of gage height are good.

MIDDLE BRANCH OF WESTFIELD RIVER AT GOSS HEIGHTS, MASS.

Location. At a single-span highway bridge in the hamlet of Goes Heights, about 

1J miles above the village of Huntington and half a mile above the confluence 

of the Middle Branch and the North Branch of Westfield River.

Records available. July 14, 1910, to December 31, 1912.

Drainage area. 53 square miles.

Gages. Standard chain gage attached to the upstream side of the bridge, read twice 

daily from July 14, 1910, to September 7, 1912. Beginning September 8, 1912, 

an automatic gage on the right bank at the upstream side of the bridge abut-
CONNECTICUT EIVER BASIN. 121

ment was used. The automatic gage is protected by a wooden shelter about 5 feet 

square and set over a timber well about 3 feet square. The well is connected 

with the river by a 4-inch cast-iron pipe, having its outer end immediately under 

the chain gage. A sloping staff gage is set in the bank of the river practically 

over the intake to serve as a check on the automatic and chain gages.

Channel. Coarse gravel and permanent.

Discharge measurements. Made by wading at low and medium stages and from 

the highway bridge at high stages.

Artificial control. The operation of a power plant about 2 miles above the station 

causes some diurnal fluctuation in the flow of this stream at low stages.

NOTE. Daily discharge tables for 1910-11 here published supersede those published in Water-Supply 

Papers 281 and 301. Measurements made during 1912 indicate that the rating curve is quite different from 

the one computed from 1910-11 measurements and is fairly well defined above 5 second-feet.

Mean daily discharge, Sept. 9, to Dec. 31,1912, computed by scaling discharge for each hour from the 

automatic bydrograph. Twenty-four hourly discharges were then averaged -to obtain the mean daily 

discharge. The gaps in this record are caused by stoppage of the clock before it was in proper adjustment.

Monthly discharge of Middle Branch of Westfield River at Goss Heights, Mass., for

1910-1912.

NOTE. Figures represent the natural flow of the stream, excepting that no correction is made for evaporation and seepage from the reservoir.

Discharge figures furnished by Mr. Lochridge, in million gallons per day; converted into second-feet by 

engineers of United States Geological Survey.

HOTJSATONIC RIVER BASIN. 

HOTJSATONIC RIVER AT GATLORDSVILLE, CONN.

Location. At the covered wooden highway bridge at Gaylordsville, about 2 miles 

below the mouth of Tenmile River.

Records available. October 24, 1900, to December 31,1912.

Drainage area. 1,020 square miles.

Gage. Chain attached to bridge; read once each day; datum unchanged.

Channel. Conditions for obtaining accurate discharge data are good.

Discharge measurements. Made from a cable 1J miles below the gage, as the 

erosa section at the bridge is unfavorable for accurate measurements.

Artificial control. Upstream, the nearest dam is at Bulls Bridge. Downstream, the 

nearest dam is at New Milford, about 7 miles below ihe station. At high stages 

backwater from the dam below may slightly affect the relation between gage 

height and discharge. Operation of power plants above the station causes a very 

marked diurnal fluctuation in the flow at this point. For this reason it is not 

advisable to attempt to estimate the daily discharge from daily gage heights, 

but the rate of flow corresponding to each gage reading is published. How near 

this rate approaches the mean for the day can not be stated at present.

Winter flow. Affected by ice for short periods.

Accuracy. A good discharge rating curve has been developed so that accuracy of 

records at this point depends entirely upon the accuracy of the gage heights.

Cooperation. Gage heights from November to April, inclusive, are furnished by 

United States Weather Bureau.

HUDSON RIVER AT NORTH CREEK, N. T.

Location. At the highway bridge in the village of North Creek, immediately above 

the mouth of North Creek, which enters the Hudson from the right.

Records available. September 21,1907, to December 31, 1912. Data also in annual 

reports of the State Water Supply Commission and the State engineer and surveyor, and in the 1911 report of the State of New York Conservation Commission.
132 SURFACE WATER SUPPLY, 1912, PART I.

Drainage area. 804 square miles.

Gage. Chain, read twice daily; datum, unchanged.

Channel. Heavy gravel; considered fairly permanent.

Discharge measurements. Made from the two-span steel highway bridge.

Artificial control. The numerous lakes and ponds in the basin of the upper Hudson have a decided effect on the low-water flow; especially is this true of Indian 

Lake.1 The use of these storage reservoirs in the spring in connection with log 

driving tends to vitiate the daily records at this station. Where possible, allowance is made for the effect of logging operations.

Winter flow. Winters are severe in the northern part of the State and determinations of flow for the winter months are approximate because of ice.

Accuracy. Discharge rating curve very well defined. Determinations of discharge 

for open-water periods considered excellent.

HUDSON RIVER AT THURMAN, N. Y.

Location. At the Delaware & Hudson Railroad bridge leading from Thurman to 

Warrensburg, about 950 feet below the highway bridge to Warrensburg, about 

2,000 feet below the mouth of Schroon River, and about 13 miles above the mouth 

of Sacandaga River, which enters from the right.
134 SUEFACE WATEE SUPPLY, 1912, PAET I.

Records available. September 1, 1907, to December 31, 1912; data also in annual 

reports of the New York State Water Supply Commission, the State engineer 

and surveyor, and the State Conservation Commission of New York.

Drainage area. 1,550 square miles.

Gage. Chain; read three times daily; datum unchanged.

Channel. Sand and gravel; liable to shift.

Discharge measurements. Made from the bridge.

Artificial control. The influence of storage at Indian Lake and of mill control on 

Schroon River is observable at this station.

Winter flow. Winter flow estimated from the determinations of combined flow at 

Eiverbank and North Creek plus an estimated inflow between the two stations.

Accuracy. Accuracy of the determinations to some extent impaired as the result 

of accumulations of logs at the control point below the section and also around 

the piers of the bridge. Discharge rating curve very well defined, and determinations of flow during the open-water season are considered fairly accurate.

Cooperation. Gage heights, January to March and December, furnished by Albany 

office of United States Weather Bureau.

NOTE. Relation of gage height to discharge affected by ice Jan. 1 to about Apr. 5. A log jam formed 

June 17 and caused some backwater at the gage for the remainder of the year. There were other log jams 

before June 17, but apparently they did not affect the gage heights.

NOTE. Discharge Jan. 1 to Apr. 5 estimated from the combined discharge of Schroon River and Hudson

Mean discharge Apr. 1 to 5 estimated 3,110 second-feet.
136 SURFACE WATER SUPPLY? 1912, PART I.

HUDSON RIVER AT CORINTH, N. Y.

Location. One-half mile upstream from highway bridge crossing the Hudson at 

Corinth and one-half mile north of the Corinth post office, at the mouth of the 

second brook, upstream, tributary to the Hudson from the right; 5 miles by 

river below the village of Luzerne and 1J miles above the dam of the International Paper Co. at Palmer Falls.

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

Drainage area. 2,760 square miles. 1

Gage. Vertical staff bolted to the left-hand abutment on the downstream side of 

the highway bridge over the brook. The gage is about 25 feet from low-water 

line in Hudson Eiver, but as there is practically no elope to the tributary stream 

low-water [readings can be considered fair. The zero of the gage, unchanged 

since established, is at the same elevation as the crest of the Palmer Falls dams, 

which is assumed as 100 feet.

Channel. Permanent; composed of coarse gravel and bowlders; fairly straight for 

upward of 2 miles above the gage, and current sluggish. The river begins to 

bend to the left almost at the gage and in the next 1,000 feet turns nearly 90°, 

then flows straight for 200 or 300 feet to the head of a rocky reef, which is practically a control for the gage. In the 1,000 feet between the point of control and 

the three-span steel highway bridge that crosses the Hudson at this point the 

river falls 3 or 4 feet.

Discharge measurements. At low and medium stages made from a boat or by 

wading just above the point of control and about 1,100 feet downstream from 

the gage; at high stages from the upstream side of the highway bridge. None 

made during 1912.

Winter flow. Ice forms in the river to a thickness of 2 or 3 feet in the vicinity of 

the gage and down to within 500 feet of the control. In a section at the control, 

however, the river is usually open and it is believed that there ia no very marked 

effect from ice.

Artificial control. The low-water flow is modified by release of stored water from 

Indian Lake and to some extent by release of water from other small ponds on 

the upper Hudson. The only dam on the main stream above the station is that 

which furnishes power to a paper mill at Luzerne, 5 miles above. Below the 

bridge and on the left-hand side of the stream is a low dam built in November, 

1905, by the Corinth Electric Power Co., to divert water to a small electric plant 

which furnishes light and power for the villages of Corinth and Palmer Falls. 

In September, 1909, a temporary brush dam was built at this point by the same 

company. The dam of the International Paper CD. is about one-half mile farther 

downstream. Neither dam affects the records at the gage.

Point of zero flow. Soundings near the point of control indicate that there would 

be no flow past the gage if the water fell below 123 feet on the gage.

Accuracy. Conditions are not entirely favorable for accurate determination of flow. 

During the greater part of the time log jams rest against the two bridge piers and 

often extend upstream above the point of control, causing back water at the gage. 

Construction work on the temporary brush dam in the fall of 1909 may have 

produced a slight effect at the gage. The discharge curve has been developed 

from measurements made by engineers of the United States Geological Survey 

and probably represents the discharge at the station fairly well for conditions 

unaffected by log jams or ice.

Cooperation. Gage installed and gage heights furnished by the International 

Paper Co.

1 The figure formerly published was 2,728 square miles, but the new figure is probably more nearly 

correct.

HUDSON RIVER AT SPIER FALLS, N. Y.

Location. On the river road, half a mile below the Spier Falls dam, about 11J 

miles below the mouth of Sacandaga Kiver. This station is most easily acressible 

from Glens Falls, N. Y., a distance of 11 miles. (See PI. Ill, B.)

Records available. October 6 to December 31, 1912.

Drainage area. 2,800 square miles (from United States Geological Survey topographic sheets).

Gage. Kecording hydrograph and auxiliary sloping staff gage. The automatic gage 

is in a brick shelter 5 feet square inside dimensions. Underneath the shelter is 

a brick well 3£ feet square, 21 feet deep. This well is connected with the river 

by a 4-inch cast-iron water pipe 78 feet long. A shear gate valve is set at the 

inner end of the pipe for use in cleaning the well when necessary. The outer 

end is fastened firmly in a concrete anchorage and is submerged at all stages. 

Inside the well is a hook gage used for setting the automatic gage. The sloping 

staff gage is mounted on small concrete piers 10 feet upstream from the shelter.

Channel. Coarse gravel and bowlders.

Discharge measurements. Made from a cable and car located about 1,000 fee* 

downstream from the automatic gage. The cable is of 450 feet span, supported 

on the left bank by a pulley hung from a frame about 4 feet high; on the right 

bank by a pulley hung from a frame about 20 feet high.

Winter flow. Ice prevails during extremely cold weather. It is not known how 

much this will affect the relation between gage height and discharge. Efforts 

will be made to obtain frequent discharge measurements.

Artificial control. Control at the Spier Falls dam is indicated by the hydrograph.

Accuracy. Very consistent meter measurements have been made covering the 

range of gage heights for 1912 and the record is excellent.

Cooperation. Station maintained in cooperation with the Adirondack Electric 

Power Corporation, the International Paper Co., the Union Bag & Paper Co., 

and the Finch, Pruyn Paper Co.

HUDSON RIVER AT MECHANICVILLE, N. Y.

Location. At the Duncan dam of the West Virginia Pulp & Paper Co., in the village 

of Mechanieville, about 3,700 feet above the mouth of Anthony Kill (coming in 

from the right), 1J miles below the mouth of Hoosic River (coming in from the 

left), and about 19 miles above the mouth of the Mohawk River, which enters from 

the right at Cohoea.
140 SURFACE WATER SUPPLY, 1912, PART I.

Records available! 1892 to-1912. Data also in annual reports of the State engineer arid surveyor -of New York, of the State Water Supply Commission of New 

York, and (for 1911) the first annual report of the State .of New York Conservation Commission. The records which have been kept at this station are among 

the longest in the State^. They have been used as basic data in all studies of storage 

problems on the upper, Hudson.

Drainage area. 4,500 square miles.

Gage. Recording gage installed at the dam in the summer of 1910 for the purpose 

of obtaining a more accurate register of the daily flow over the crest of the dam; 

previous to 1910 two gage readings daily on the crest of the dam.

Discharge measurements. Determinations of discharge for periods previous to 

the summer of 1910 computed by using two daily gage readings on the crest of the 

dam and continuous record of the run of the wheels in the adjoining paper mill. 

In 1904 the dam was raised and a concrete crest and apron were added, so that it 

now has a rounded or ogee section. A discharge curve has been calculated by 

means of coefficients derived from the United States Geological Survey experiments on dams of ogee section.

Accuracy. Records at this station are very carefully made and may be considered 

good for this type of station. In using these records it should be remembered that 

water is diverted past this station in the Champlain Canal.

Diversions. Water is diverted past this station through the Champlain Canal. No 

correction has been made for this diversion. During 1912 the canal was in 

operation from about May 5 to Dec. 1. See Water Supply Paper 281, page 193.

Cooperation. Records are computed and furnished by Mr. R. P. Bloss, engineer of 

the West Virginia Pulp & Paper Co.

CEDAE RIVER NEAR INDIAN LAKE, N. Y.

Location. At the steel highway bridge about 2 miles west of Indian Lake village, 

on the road leading to Blue Mountain Lake, about 12 miles by river above its 

confluence with the Hudson, 8 miles by river above the mouth of Rock River 

(tributary from the left) and 10 miles by river below Cedar River Flow (Wakely 

dam).

Records available. July 15, 1911, to December 31, 1912. Published also in first 

annual report of State of New York Conservation Commission.

Drainage area. 85 square miles.

Gage. Standard chain and weight.

Channel. Coarse gravel and small bowlders, fairly permanent. Low-water control 

is gravel rift about 200 feet below the bridge.

Storage. The basin contains many lakes and swamps affording favorable sites for 

storage reservoirs which would be influential in regulating the discharge of Hudson 

River. Those that are important are Cedar Lakes and Cedar River Flow. Cedar 

River Flow is controlled by a lumberman's dam and is used principally during 

the logging season.

Accuracy. Discharge rating curve fairly well defined.

144 SURFACE WATER SUPPLY, 1912, PART I.

INDIAN LAKE RESERVOIR AT INDIAN LAKE, N. Y.

Location. At the masonry storage dam at the outlet of Indian Lake, about 7J miles 

above the confluence of Indian River with the Hudson and about 23J'miles 

above the village of North Creek.

Records available. July 22,1900, to December 31,1912. Data also in annual reports 

of the State engineer and surveyor, State Water Supply Commission, and State 

Conservation Commission.

Drainage area. 131 square miles, including about 9.3 square miles of water surface 

of Indian Lake at the elevation of the spillway of the dam.

Gage. Staff; read once daily. November 17, 1911, a chain gage was installed on 

the crest of the dam to replace the staff gage. Datum of both gages the same 

and unchanged since the establishment of the station.

Discharge measurements. The record of this station includes elevation of water 

surface in the reservoir, depth of water flowing over the spillway or flashboards, 

depth of opening, and the effective head on each of the 5-foot sluice gates. A 

meteorologic station has also been established at the dam by the United States 

Weather Bureau and records are kept of the rainfall, temperature, etc. The crest 

of the dam is 106.05 feet in the clear. To facilitate the calculation of discharge 

over the spillway, experiments were made at Cornell University in 1899 on a 

full-size model of the spillway section, 6.58 feet long, from which the coefficient 

of discharge has been determined. No computations of discharge have been 

made pending current meter measurements to rate discharge through gates. At 

present, records of reservoir level and gate openings are available. The elevation 

of the crest of the spillway above mean tide is 1,650 feet.

Artificial control. The flow of the upper Hudson has been controlled to a considerable extent during the dry season by the use of Indian Lake reservoir since 

its completion in 1899. The storage provided, about 4,700,000,000 cubic feet, 

affording a discharge of nearly 600 second-feet for a period of 90 to 130 days 

each year.

Maximum and minimum gage heights. Maximum gage height at Indian Lake 

Reservoir since the establishment of the station recorded April 27, 1908, 37.00 

feet; minimum gage height, recorded March 9 to 18, 1907, and January 3 to 17, 

1910, 2.00 feet.

Daily gage height, in feet, of Indian Lake Reservoir at Indian Lake, N. Y.,for 1912.

a This date not recorded. Estimated from gage heights on Indian River at Indian Lake.

INDIAN RIVEE NEAE INDIAN LAKE, N. Y.

Location. About three-fourths of a mile below State dam, at the outlet of Indian 

Lake, 1 mile above the mouth of Big Brook (the only important tributary of 

Indian River below this station), and 8 miles above the point where it enters 

the Hudson.

Records available. Miscellaneous measurements, 1911; July 1 to December-31, 

1912.

Drainage area. 132 square miles.

Gage. Vertical staff, nailed to stump.

Channel. Pond of still water at head of rocky rapids; a well-defined, permanent, 

rock control exists below the station.

Artificial control. The flow of Indian River is controlled at the lake.

Discharge measurements. Made by wading at head of rapids about 150 feet 

below gage.

-Winter flow. Because of the swift current in the rapids the water probably never 

freezes on the control and, although ice will form around the gage in the still 

water, the relation of gage height to discharge will probably not be seriously 

affected.

Accuracy. The rating curve is not yet developed.

Discharge measurements of Indian River near Indian Lake, N. Y., in 1912.

HUDSON EIVEE BASIN. 147

SCHROON EIVEE AT BIVEEBANK, N. T.

Location. At the highway bridge 12 miles above the confluence of Schroon River 

with the Hudson, 9 miles below the mouth of Schroon Lake, about 3 J miles below 

the outlet of Brant Lake (coming in from the left), and 1 mile below Tumblehead 

Falle, which extend upstream about a mile farther. The station is about 9 miles 

north of Warrensburg, where there are several dams used for power development.

Records available. September 2,1907, ^o December 31,1912. Data also in annual 

reports of New York State Water Suppljy Commission, State engineer and surveyor, 

and State Conservation Commission.

Drainage area. 534 square miles.

Gage. Chain; read once daily; datum unchanged.

Channel. Gravel; smooth and permanen^.

Discharge measurements. Made from the bridge.

Artificial control. Since 1907 the regimen of flow of Schroon River, from the lowwater period to the high, has been pomewhat affected by storage in Schroon 

Lake. In September, 1907, a timber brib dam was constructed at Starbuckville 

about 6 miles above the station. This dam affords a head of about 8 feet and 

ponds water to Schroon Lake.

Winter flow. Affected by ice.

Accuracy. Open-water curve well developed. Measurements made through the 

ice have developed a fairly good ice-discharge curve.

Discharge measurements of Schroon fewer at Riverbank, N. Y., in 1912.

SACANDAGA RIVER NEAR HOPE, N. Y.

Location. About 3J miles above the post office at Hope, 4 miles below the village of

Wells, 12 miles above Northville (the nearest railroad station), and 1J miles below

the junction of the East and West branches of the Sacandaga. (See PI. Ill, A,

p. 138.)

Records available. September 15, 1911, to December 31, 1912. 

Drainage area. 494 square miles. 

Gage. Staff in two sections; a sloping staff reading from 1.00 foot to 4.30 feet, on a

slope of 2.5 to 1; a vertical staff (for high water records) attached to a rocky cliff

in line with the sloping gage. 

Channel. Very rough, but permanent; banks are fairly free from timber; high and

rocky; channel has been cleared of bowlders to some extent. 

Discharge measurements. Made from a cable with a span of 214 feet. 

Accuracy. The open-water rating curve is well defined and estimates for this period

are good.

152 SURFACE WATEE SUPPLY, 1912, PART I.

SACANDAGA RIVER AT HADLEY, N. Y.

Location. About half a mile west of the railroad station at Hadley, 1 mile above 

the confluence of Sacandaga River with the Hudson, and 4J miles below the 

site of the proposed storage dam at Conklingville. No tributaries between this 

station and the mouth of the river. Location selected to avoid inaccuracies in 

the records caused by backwater from log jams. This station replaces the upper 

bridge station and the lower bridge station.

Records available. September 13, 1907, to December 31, 1910, upper bridge 

station; September 24, 1909, to July 7, 1911, lower bridge station; January 1, 

1911, to December 31, 1912, present station. Data also in annual reports of the 

New York State Water Supply Commission, State Conservation Commission, 

and State engineer and surveyor.

Drainage area. 1,060 square miles.

Gage. Recording hydrograph 30 feet downstream from the cable, in a concrete well 

3 feet square, inside dimensions. The bottom of the well is about 2 feet below 

low water and 12 feet below ground surface. It is connected with the river by a 

4-inch castxiron water pipe 48 feet Icing, its intake end pointing downstream and 

protected by a fine wire screen. Inside the well and securely bolted to the side 

is a staff gage, its zero at elevation 573.36 and referred to a United States Geological Survey aluminum tablet set in the foundation wall of the Union Bag & 

Paper Co.'s mill at Hadley. On top of the well is a concrete shelter 6 feet high 

and 3 feet square, inside dimensions, for protecting the recording gage. The staff 

gage is used only as a reference gage.

Channel. Very rough but permanent. The channel at the cable was cleared of 

bowlders as far as feasible, so that fairly accurate discharge measurements can 

be made at medium and high stages. Low-water measurements are made at a 

section about three-fourths of a mile above the cable, where the bottom is smooth 

and gravelly.

Discharge measurements. At medium and high stages, made from cable; at low 

stages, made from a boat or by wading at a section about three-fourths of a mile 

above the cable.

Winter flow. The water in the well and in the intake pipe never freezes because 

its level^is below the frost line. The relation of gage^ height to discharge is, 

however, considerably affected by ice in the river.

Accuracy. The discharge rating curve which has been developed for this station is 

well denned.

NOTE. Relation of gage height to discharge affected by ice Jan. 9 to Apr. 3. On days having little fluctuation in stage the mean gage height was obtained by an inspection of the hydrograph traced by the gage; 

on days when the fluctuation was considerable the mean gage height is the average of 6 readings during 

each 24-hour period.

WEST BRANCH OF SACANDAGA RIVER AT BLACKBRIDGE, NEAR WELLS,

N. Y.

Location. On the highway bridge known as Blaokbridge, about 3 miles west of

Wells and 2 miles above the junction of the East and West branches of Sacandaga

River. Replaces station formerly located at Whitehouse. 

Records available. March 14, 1911, to December 31, 1912. 

Drainage area. 211 square miles. 

Gage. Chain, attached to upstream side of the highway bridge; read twice daily;

datum unchanged.

Channel. Rocky and practically permanent; two channels at extreme high water. 

Discharge measurements. Made from the bridge and by wading. Section

beneath the bridge was cleared of bowlders in September, 1911. 

Artificial control. Gage heights slightly affected by storage dams used for logging

in the spring. 

Winter flow. Probably little affected by ice. Stream open during greater part of

the winter. 

Accuracy. The open-water rating curve is very well defined. Estimates for this

period are good.

HUDSON EIVEE BASIN. 157

HOOSIC RIVER NEAR EAGLE BRIDGE, N. Y.

Location. 1£ miles above the village of Eagle Bridge and \ mile below the mouth 

of Walloomsac River coming in from the right. Owlkill Creek enters from the 

right at Eagle Bridge. Replaces station formerly maintained at Buskirk. The 

Buskirk station was abandoned because the relation between gage height and 

discharge was affected by backwater caused by the construction of a dam at 

Johnson ville.

Records available. August 13, 1910, to December 31, 1912. For the station formerly maintained at Buskirk, 4 miles below, records are available from September 25, 1903, to December 31, 1908. Data published also in annual reports 

af New York State engineer and surveyor.

Drainage area. 512 square miles.

Gage. Standard chain, supported by cantilever arm on a tree on the left bank about 

400 feet above the residence of James Russell. Datum unchanged.

Channel. Bed of river composed of gravel; liable to shift. Control point about 400 

'eet below the gage.

Discharge measurements. At low stages made by wading; at high stages formerly made from the highway bridge in the village of Eagle Bridge, \\ miles 

>elow. A cable was erected at this station during 1912, J mile below the gage 

'or high-water measurements.

Artificial control. The dam of Walter A. Wood & Co. is located at Hoosic Falls, 

about 2 miles above the gage. Walloomsac River is also partly controlled, and 

the effect of the operation of the mills is observable at the gage. On this account 

the gage heights should be used with caution.

Accuracy. Except for possible inaccuracies in gage heights due to artificial control 

: records are good.

EAST CANADA CHEEK AT DOLGEVILLE, N. Y.

Location. At the dam of the Herkimer County Light & Power Co. at High Falls, 

near Dolgeville, about 7 miles above the mouth. Spruce Creek, the principal 

tributary, enters from the right about 1 mile above Dolgeville.

Records available. 1898 to 1912. Data also in the report of the Board of Engineers 

on Deep Waterways (1900) and the annual reports of the New York State engineer 

and surveyor.
HUDSON KIVEB BASIN. 165

Drainage area. 256 square miles.

Computations of discharge. Discharge at this point consists of the flow over the 

spillway of the dam and the flow through the water wheels. The records have 

been computed from a discharge curve based on experiments with a full-sized 

model of this dam made at Cornell University. The flow through the turbines 

has been computed from current meter measurements made in the tailrace of 

the power plant.

Cooperation. Records furnished for publication by the State engineer and surveyor.

Daily discharge, in second-feet, of East Canada Creek at Dolgeville, N. Y1., for

Day.

166 SUEFACE WATEE SUPPLY, 1912, PAET I.

SCHOHAEIE CREEK AT PEATTSVILLE, N. Y.

Location. At the single-span steel highway bridge at Prattsville.

Records available. November 7, 1902, to December 31, 1912. Data also in reports 

of State engineer and surveyor, State of New York.

Drainage area. 240 square miles.

Gage. Standard Board of Water Supply chain gage attached to the floor of the bridge 

on the upstream side near the left bank; established May 7, 1907, to replace the 

old gage, which was dilapidated and unwieldy. The old datum, 1,130.03 feet 

(United States Geological Survey bench mark), was preserved. Gage was read 

morning and evening by Miss Edna M. Snyder, of Prattsville, N. Y., until September 30, 1910, and by her brother, Charles Snyder, after that date.

Channel. All the water passes between the abutments of the bridge except at the 

very highest stages.

Discharge measurements. Made from the bridge at high stages; at low stages 

measurements may be made by wading at a point about 500 feet below the bridge.

Winter flow. The winter record is obtained from a temporary gage established at a 

point about 500 feet below the bridge, where there is a sufficient velocity to 

prevent the channel from freezing over.

Artificial control. Flow probably practically unaffected by fluctuations of stage 

from storage above Prattsville.

Cooperation. Station assumed May 7, 1907, by the Board of Water Supply of the 

City of New York, by which data were furnished for publication.

Daily discharge, in second-feet, of Schoharie Creek at Prattsville, N. Y., for 1912.

KINDERHOOK CREEK AT ROSSMAN, N. Y.

Location. On highway bridge at Rossman, N. Y., 3J miles above the confluence of 

the creek, through Stockport Creek, with Hudson River, 1 mile above the mouth 

of Claversack Creek, which it joins to form Stockport Creek, and 9 miles by road 

above the village of Hudson.

Records available. March 17, 1906, to December 31, 1912. Data published also in 

annual reports of State engineer and surveyor, State of New York.

Drainage area. 331 square miles.

Gage. Tape and weight type attached to highway bridge; read twice daily; datum 

unchanged since established.

Channel. Rock with some soil on sides.

Discharge measurements. Made from single-span steel highway bridge.

Artificial control. Low-water flow practically controlled by several power plants 

and paper mills above the station. Several small lakes also tend to affect lowwater flow for short periods.

Winter flow. Considerably affected by ice.

Accuracy. Open-channel discharge rating curve very well defined. Accuracy of 

estimates depends entirely on accuracy of mean daily gage heights. '' See Special 

study" below.

Special study. A portable automatic gage was set up near the observer's gage and 

a continuous automatic record of gage heights was obtained from August 3 to 

August 12, and November 30 to December 5,1912, inclusive. The true mean daily 

discharge was determined from hourly gage heights from the continuous record 

and was compared with the discharge obtained from semidaily observations. It 

appeared that daily discharges computed from semidaily observations were 

fairly good for discharges above 100 second-feet. The mean daily gage heights 

obtained from semidaily observations are being published, together with estimates for the periods when the daily discharge is above 100 second-feet. Further studies will be made with a view to determining whether gage readings for 

low-water periods can be made more valuable.

ESOPUS CREEK NEAR OLIVEBRIDGE, N. Y.

Location. About 1 mile below Olivebridge post office, at a weir constructed for the 

purpose of determining the flow of the creek.

Records available. October 17, 1906, to December 31, 1912. Data also in annual 

reports of the New York State engineer and surveyor

Drainage area. 239 square miles.

Gage. Automatic water-stage register geared 1 to 1 and running 24 hours, in a 

well 24 inches in diameter, situated 53 feet upstream from the crest of the weir. 

Water is admitted to this well through a three-fourths-inch pipe extending 16 feet 

out into the stream in which, spaced 6 inches apart, are one-eighth-inch holes 

bored vertically through the pipe. The center of this pipe is 18 inches above the 

bed of the stream. The automatic gage was installed December 5, 1906. From 

October 17, 1906, to December 5, 1906, head of water on the weir was read three 

times daily and reduced in the usual manner.

Discharge measurement. Computations of discharge over the weir are made from 

a formula deduced from the results of experiments made by the United States 

Geological Survey in the hydraulic laboratory at Cornell University in series 30, 

described in Water-Supply Papers 150 and 200. The weir is of concrete, 193.90 

feet between abutments and 7.54 feet (average height for entire length) above 

the rock in which it is founded. To form a channel of approach the abutments 

have been extended upstream at right angles with the axis of the weir for a distance of 16 feet; area of channel of approach below crest of weir, 1,462 square 

feet. Abutments extend 14 feet above the level of the crest; it is estimated that 

a flow of 40,000 cubic feet per second can be taken care of.

Winter flow. The ice which forms between the wing walls which define the channel of approach is kept cut away during the winter so that there may be no change 

in conditions of flow caused by ice.

Artificial control. The effect of such slight fluctuations in daily stage as may 

result from power control above Olivebridge is practically eliminated from the 

records by the use of the automatic gage.

Cooperation. Weir constructed and operated and data furnished for publication by 

the Board of Water Supply of the city of New York.

ESOPUS CREEK AT MOUNT MARION, N. Y.

Location. At the single-span steel highway bridge at Pleasant Valley, on the 

Saugerties road, 1 mile east of Mount Marion station on the West Shore Railroad.

Records available. April 4, 1907, to December 31, 1912. Data also in annual 

reports of State engineer and surveyor, State of New York.

Drainage area. 378 square miles.
172 SUBFACE WATEK SUPPLY, 1912, PAET I.

Gage. Standard Board of Water Supply chain gage fastened to the downstream side 

of the bridge, read twice daily. In May, 1908^ the floor of the bridge was renewed, 

but provision was made for accurate gage readings during that period.

Channel. Straight for about 1,000 feet above the station and 600 feet below, one at 

all stages. Bed, ledge rock with strata steeply inclined, giving jagged corners 

and irregular but permanent cross section. Banks rocky and steep; right bank 

about 40 feet above water level; left bank at least 100 feet high.

Discharge measurements. At high stages made from the bridge; at low stages at 

a wading section three-fourths of a mile above the bridge and about three-fourths 

of a mile below Glenerie Falls; 200 feet from the Kingston-Saugerties road which 

parallels the creek on the right bank. At the wading section, which is used only 

when the water is less than 3 feet deep, the bed is gravelly and liable to some 

change, but the current is swift and good measurements are obtained. The banks 

at the wading section are of the same character as those at the bridge.

Winter flow. Affected by ice. Measurements through the ice; gage readings to ice 

and water.

Accuracy. Such slight fluctuation in daily stage as may result from the operation 

of the power plants above Mount Marion probably causes no material error in the 

estimates of daily discharge.

Cooperation. Established and maintained and records furnished for publication by 

Board of Water Supply, city of New York. Gage read morning and afternoon 

by John Sauer, of Saugerties.

Daily discharge, in second-feet, of Esopus Creek at Mount Marion, N. Y., for 1912.

EONDOUT CREEK AT ROSENDALE, N. Y.

Location. At single-span steel highway bridge at Rosendale.

Becords available. July 6, 1901, to December 31, 1912, except from November 7, 

1903, to December, 1905. Data also in annual reports of the State engineer and 

surveyor, State of New York.

Drainage area. 380 square miles.

Gage. Standard Board of Water Supply chain gage fastened to the middle panel of 

the downstream side of the bridge. This gage was established June 1, 1907, to 

replace the original gage.

Channel. One at all stages.

Discharge measurements. At high and medium stages made from the bridge; 

at low stages by wading at a point about 1,000 feet below the bridge.

Winter flow. The winter flow is obtained by actual measurements at selected 

stations on the creek through the ice and by wading, and by comparison with 

gage readings to water and ice at the bridge.

Diversions. A portion of the water of the creek is diverted by a dam below High 

Falls and sent through the Delaware & Hudson Canal, and is returned to the 

creek below the gaging station. At Rock Locks, about 1J miles below Rosendale, 

there is an overflow weir from which the discharge of the canal may be approximately determined. The weir, the crest of which is 3.8 feet in length, is at the 

left end of the lock and is equipped with a standard Board of Water Supply staff

Artificial control. Slight daily fluctuations in stage are caused by storage at Honk 

Falls, Napanoch, and to some extent at High Falls. Proper allowance is made 

in the daily discharge records for the water diverted to the Delaware & Hudson 

Canal.

Cooperation. Data furnished for publication by the Board of Water Supply of the 

City of New York, by which the station was assumed on June 1, 1907.

176 SURFACE WATER SUPPLY, 1912, PART I.

EAST BRANCH OP DELAWARE RIVER AT HANCOCK, N. Y.

Location. At the highway bridge Tialf a mile southeast of the Erie "Railroad station 

at Hancock, N. Y., about 1 mile above the junction of East and West branches of 

Delaware River and 10 miles below the mouth of Beaver Kill, the nearest tributary, which enters from the left.

Records available. October 14, 1902, to December 31, 1912. Data also in annual 

reports of New York State engineer and surveyor.

Drainage area. 840 square miles. 1

Gage. Standard chain, fastened to upstream left-hand end of bridge; read once 

daily; datum unchanged.

Channel. Both banks of medium height; not liable to overflow; bed composed of 

_ rocks and gravel.

Discharge measurements. Made from the bridge or by wading.

Winter flow. Affected by needle and cake ice which forms on the control point and 

produces backwater at the gage.

Accuracy. Conditions fairly good for accurate determinations of discharge. Highwater stage probably affected at times by backwater caused by gorging at junction 

with the West Branch. Low- water discharge controlled by riffles just below 

Erie Railroad bridge which sometimes shift and require many measurements and 

possibly a new discharge rating curve each year. Conditions, however, have been 

fairly permanent during the last two or three years.

Cooperation. Maintained since January 1, 1908, in cooperation with the United 

States Weather Bureau.

DELAWARE RIVER AT PORT JERVIS, N. Y.

Location. At the toll bridge at Port Jervis, 6 miles below the mouth of Mongaup 

River and 1 mile above the mouth of Neversink River, both entering from the

north.

Records available. October 12, 1904, to December 31, 1912. Data published also 

in the annual reports of the New York State engineer and surveyor.

Drainage area. 3,250 square miles.

Gage. Standard chain, fastened to downstream side of bridge; read once daily. 

Considerable difficulty has been experienced in maintaining the datum of the 

gage. On September 4, 1908, in order to avoid negative readings, a change of 

about 2 feet was made in the original datum, as nearly as could be determined. 

The elevation of the datum of .the gage is 414.89 feet above mean sea level. A 

correction varying from -f- 1.7 to +2.0 has been applied to gage heights previous 

to September 4,1908, so that all gage heights published by the Survey are referred 

to the same datum.

Channel. Bed composed of gravel; banks high; seldom overflowed.

Discharge measurements. Made from the highway bridge, except at low stages, 

when the left channel is sometimes measured by wading.

Winter flow. Relation of gage height to discharge is usually not greatly affected by 

ice, except during severe winters. Ice jams sometimes occur at this station and 

the left channel is particularly subject to effect from ice.

Accuracy. Conditions of flow at this point are constant and a good discharge rating 

curve has been developed for all stages. Careful comparison of records at this 

station with those obtained at Riegelsville and the two Hancock stations indicate 

that all the discharge data are reliable.

Cooperation. Station established for the United States Weather Bureau by Irving 

Righter, city engineer of Port Jervis. Gage heights supplied to the Geological 

Survey by the Weather Bureau.

NOTE. Discharge Jan. 13 to Mar. 13, inclusive, estimated by comparison with the station at Riegelsville, taking climatologic conditions into consideration.

DELAWARE RIVER AT RIEGELSVILLE,' N. J.

Location. At the toll suspension bridge between Riegelsville, N. J., and Riegelsville, Pa., 9 miles below the mouth of Lehigh River (entering from the west) and 

600 feet above the mouth of the Musconetcong (entering from the east).

Records available. July 3, 1906, to December 31, 1912.

Drainage area. 6,430 square miles.

Gage. Chain, attached to the bridge; datum unchanged.

Channel. The station is in a deep hole which extends about half a mile downstream 

to a permanent control composed of bowlders averaging 2 to 3 feet in diameter; 

immediately below the control are heavy rapids. Both banks are high and not 

subject to overflow.

Discharge measurements. Made from the bridge. No measurements in 1912.

Winter flow. Relation between gage height and discharge affected by ice only 

during severe winters.

Diversions. The Delaware division of the Pennsylvania Canal, running from 

Easton, Pa., to Bristol, Pa., diverts water from the Lehigh at its mouth and at 

low stages takes practically the entire discharge of this tributary. The water is 

turned out of this canal during the winter period, or from about the middle of 

December to the last of March, but throughout the remainder of the year the average discharge is 250 to 300 second-feet.

Accuracy. Conditions for obtaining accurate discharge data are very good, and an 

excellent discharge rating curve has been developed. The relation between gage 

height and discharge is affected by backwater from the Musconetcong only at 

rare intervals. Comparison of the records of flow with those at Port Jervis, N. Y., 

and Hancock, N. Y., show that full reliance can be placed on the estimates of 

monthly discharge at Riegelsville.

NOTE. In order to determine the discharge per square mile and the run-off depth in inches, 270 secondfeet were added Mar. 25 to Dec. 8, 1912, before computing the discharge per square mile: Hence the first 

three columns indicate the actual quantity of water available in the river, and the two remaining columns 

represent the actual run-off from the drainage area above Riegelsville, including the discharge of the canal.

WEST BRANCH Or DELAWARE RIVER AT HALE EDDY, N. Y.

Location. At highway bridge 400 feet west of the Erie Railroad station in the village 

of Hale Eddy, 8f miles above junction with East Branch at Hancock, 8 miles 

below the power dam of the Deposit Electric Co.

Records available. November 15 to December 31, 1912.

Drainage area. 611 square miles (Post Route Map).

Gage. A vertical staff gage in four sections.

Channel. Bed of stream consists of coarse gravel and bowlders. The control is 

about three-fourths mile below the gage and is apparently permanent. Between 

the control and the gage there is low land behind the left bank which is overflowed by extreme high water.

Discharge measurements. Made by wading across three channels above the 

bridge or one below, in low water. High-water measurements may be made 

from highway bridge.

Winter flow. Gage heights seriously affected by ice during the winter months.

Accuracy. Discharge rating curve well defined. Good conditions for meter measurements.

The following discharge measurement was made by Frank Weber: 

November 21, 1912: Gage height, 2.99 feet; discharge, 646 second-feet.

WEST BRANCH OF DELAWARE RIVER AT HANCOCK, N. Y.

Location. At the toll suspension bridge over Delaware River half a mile west of the 

Erie Railroad station at Hancock, N. Y., about 1 mile above the junction of the 

East and West branches of the Delaware, and about 10 miles below the mouth of 

Oquaga Creek, the nearest tributary, which enters from the right.

Records available. October 15, 1902, to December 31, 1912. Data published also 

in annual reports of the New York State engineer and surveyor.

Drainage area. 660 square miles. 1

Gage. Standard chain, fastened to the upstream side of the bridge; read once daily; 

datum unchanged.

Channel. Bed of river composed of gravel; one channel at all stages.

Discharge measurements. Made from the bridge or by wading.

Winter flow. Affected considerably by ice below the control point.

i Revised value.
184 SURFACE WATER SUPPLY, 1912, PART I.

Accuracy. Conditions for determination of discharge not good. High-water stage 

affected by backwater from East Branch; low-water stage controlled by rifflea 

about 800 feet below the bridge; frequent changes in the channel require many 

measurements and frequent new discharge rating curves.

Cooperation. Maintained since January 1, 1908, in cooperation with the United 

States Weather Bureau.

186 SUEFACE WATEE SUPPLY, 1912, PART I.

MONGAUP EIVER AT RIO, N. Y.

Location. At the steel highway bridge on Partridge ranch, near Rio, 6 miles above

Mongaup village and some 7 miles above the mouth of the stream. 

Records available. August 8, 1909, to December 31, 1912. Data also in annual

report of New York State engineer and surveyor. 

Drainage area. 189 square miles. 

Gage. Standard chain, attached to the downstream side of the bridge; read twice

daily; datum unchanged. 

Channel. At low and medium stages divided into two parts by an island just below

the bridge. Banks high and overflow only during high stages. 

Discharge measurements. At high stages made from the bridge; at low stages by

wading. 

Accuracy. Conditions fairly good except at low-water stages, when the current

becomes rather sluggish. A good discharge rating curve has been developed for

stages below 3 feet.

The following discharge measurement was made by Frank Weber: 

July 30, 1912: Gage height, 0.70 foot; discharge, 41.6 second-feet.

Daily gage height, in feet, of Mongaup River at Rio, N. Y.,for

NEVERSINK RIVER AT GODEFFROY,, N. Y.

Location. At the suspension bridge half a mile east of the post office at Godeffroy, 

half a mile below the mouth of Brasher Kill (entering from the left), and 8 miles 

above the confluence of Neversink and Delaware rivers.

Becords available. August 4 to October 9, 1903; August 21 to December 25, 1909. 

Data also in the annual reports of the State engineer and surveyor of New York.

Drainage area. 314 square miles.
188 SURFACE WATER SUPPLY, 1912, PART I.

Gage. Present gage, established August 1, 1910, standard chain, supported by a 

cantilever arm fastened to the left-hand downstream cable tower; datum of 

present gage (unchanged) is 0.98 foot lower than that of original gage washed out 

by flood October 9, 1903, and the same as that of second gage, an enameled staff 

bolted to the downstream end of left-hand abutment; destroyed by flood January 21, 1910; gage read twice daily, about 8 a. m. and 5 p. m.

Channel. Bed of sand and gravel; liable to shift.

Artificial control. There are several reservoirs in the upper part of the drainage area, 

two of which are now in use. The principal power plant is at Roses Point, near 

Cuddebackville, in the vicinity of the old Delaware & Hudson canal. About 

half a mile above this point a concrete dam diverts water through the old feeder 

ditch to the plant. This power plant supplies Port Jervis, Middletown, and 

other small places in the vicinity, with electric light and power. The low-water 

flow is controlled absolutely by the power plant. For this reason it is not advisable 

to attempt to estimate the daily discharge from semidaily gage readings at present. 

The gage reader's observations are being published, together with the rate of flow 

corresponding to each.

Accuracy. Conditions are good for making measurements, but the channel is liable 

to shift from time to time, thus impairing the accuracy of the discharge rating 

curve. The curve for 1911 and 1912 is fairly good, and the accuracy of the records 

for these years depends on the accuracy of mean daily gage heights.

NOTE. Relation of gage height to discharge affected by ice Jan. 1-7,1911, and Jan. 7-Mar. 9,1912. Discharge determined from a fairly well defined rating curve.

LEHIGH EIVEE AT SOUTH BETHLEHEM, PA.

Location. On the New Street Bridge connecting Bethlehem and South Bethlehem, Pa.

Records available. September 22, 1902, to February 13, 1905; April 26, 1909, to 

December 31, 1912. Complete data 1902 to 1909 are published in Water Supply 

Paper 261.

Drainage area. 1,235 square miles.

Gage. Chain and weight, similar to that employed when the station was first established; datum of the present gage 0.09 foot higher than that of the old one used 

prior to 1909; elevation of the zero of the present gage 210.64 feet above sea level.

Channel. Straight for one-third mile above and several hundred feet below the 

station. A low rubble dam crosses a portion of the channel a few hundred feet 

below the bridge. The construction of this dam caused an alteration in the rating 

curve for 1902 and certain changes in the dam caused a further slight change in 

the rating curve between 1905 and 1909. The river bed consists of sand, gravel, 

and bowlders, and seems to be fairly permanent. Velocity good at low stages. 

Left bank low and overflows at high stages; right bank is high and does not 

overflow.

Discharge measurements. Made from the bridge.

Winter flow. Relation between gage height and discharge at this station is little 

affected by ice.

Canal. Lehigh Canal follows the left bank and passes over Monocacy Creek and 

under the left span of the bridge. The creek also passes under the bridge and 

enters the river a short distance below. An ice plant and gristmill take water 

from the canal and return it to the river above the bridge. The canal is measured 

at Main Street Bridge, one-third mile above the station, and the discharge, reduced 

by the amount of tailrace- flow of ice plant and gristmill, is added to the river 

discharge. At high stages the river overflows into the canal and creek.

Accuracy. Good.

Cooperation. Since its reestablishment this station has been maintained by the 

Water Supply Commission of Pennsylvania, and many of the measurements 

have been made by students of Lehigh University, under the direction of the 

civil-engineering department.

SUSQUEHANNA EIVEE AT BINGHAMTON, N. Y.

Location. At the Washington Street Bridge in Binghamton, about 800 feet above 

the mouth of Chenango River. No important tributaries between the station 

and the mouth of Unadilla Creek, about 50 miles upstream.

Records available. July 31, 1901, to December 31, 1912. Data also in annual 

reports of State engineer and surveyor, State of New York.

Drainage area. 2,400 square miles.

Gage. Standard chain fastened to upstream side of bridge, read twice daily; datum 

unchanged.

Channel. Bed composed of rocks and gravel. -Current swift but somewhat irregular. 

Channel at times clogged with grass and bars.

Discharge measurements. Usually made at the Exchange Street Bridge, 1,900 

feet above the Washington Street Bridge.

Artificial control. 2,800 feet upstream from the bridge is a timber crib dam affording 6 feet head; used for power development. There is no material control of 

the water by this dam.

Winter flow. As a rule not greatly affected by ice.

Accuracy. Discharge rating curve for low and medium stages is not well developed. 

The measurements plot erratically due to changes in conditions of flow. Highstage gage heights liable to considerable error because of backwater from ice jams 

which form near Willow Bend and also by backwater from Chenango Eiver. 

Published data not very satisfactory.

Cooperation. Gage heights for 1912 furnished by the United States Weather Bureau.

SUSQUEHANNA RIVER AT WILKES-BARRE, PA.

Location. At the Market Street Bridge, Wilkes-Barre.

Records available. 1888 to December 31, 1912.

Drainage area. 9,810 square miles.

Gage. The Weather Bureau gage, on which readings were begun in 1888, was on 

the left pier of the bridge. A chain gage established by the United States 

Geological Survey in 1899 was fastened to the bridge and its datum was made 

4 feet lower than the datum of the Weather Bureau gage to avoid negative readings. This datum was soon after adopted by the Weather Bureau. Since April 

1, 1905, when the Survey discontinued reading the gage, the gage heights have 

been furnished by the Weather Bureau. On July 20, 1910, the Weather Bureau 

installed a Mott type gage in the same position and at the same datum as the 

chain gage. The datum adopted by the United States Geological Survey gage 

has remained constant. Records obtained by the Weather Bureau prior to the 

adoption of the Geological Survey gage datum should have 4 feet added to 

reduce them to the present datum.

Channel. The station is situated in a deep pool with steep high banks which seldom 

overflow.

Discharge measurements. Made from the bridge.

Winter flow. Relation between gage height and discharge at this station affected 

by ice during the winter. Water is often backed up many feet by ice gorges.

Accuracy. Conditions of flow subject to change at irregular intervals. A fairly good 

discharge rating curve has been developed.

Cooperation. Complete data for this station were furnished by the Water Supply 

Commission of Pennsylvania, but their computations were revised slightly by 

the Geological Survey.

The following measurement was made by Boehringer and Reckord: 

May 21, 1912: Gage height, 7.39 feet; discharge, 18,000 second-feet.
204 SURFACE WATER SUPPLY, 1912, PART I.

NOTE. Discharge Jan. 6-Feb. 25 estimated, on account of ice, from climatologic records, and the flow at 

adjacent stations. Mean discharge Jan. 6-31 estimated 6.400 second-feet; mean discharge Feb. 1-25 estimated 6,000 second-feet. Monthly discharge changed slightly to conform with survey computation rules.

SUSQUEHANNA RIVER AT DANVILLE, PA.

Location. At the Mill Street Bridge in Danville, 52 miles below Wilkes-Barre, and 

1 miles above the mouth of the West Branch of the Susquehanna. No important tributaries enter the Susquehanna within several miles of the station.

Records available. March 25, 1899, to December 31,1912.

Drainage area. 11,100 square miles.

Gage. Chain attached to the bridge March 24, 1905. On March 9, 1904, the bridge 

to which the gage was attached was carried away by an ice freshet and from that 

date until the spring of 1905, when the new steel bridge was completed, observations were made from temporary gages and were constantly liable to error for 

stages less than 5 feet. Except during this period, the datum of the chain gage 

has remained constant.

Channel. Practically permanent.

Discharge measurements. Made from the bridge.

Winter flow. Considerably affected by ice.

Accuracy. An excellent discharge rating curve has been developed.

Cooperation. Complete data for 1912 furnished by Water Supply Commission of 

Pennsylvania.

The following discharge measurement was made by Boehringer and Reckord: 

May 20, 1912: Gage height, 7.55 feet; discharge, 25,600 second-feet.

Daily gage height, in feet, of Susquehanna River at Danville, Pa., for 1912.

NOTE. Discharge Jan. 6 to Feb. 26 estimated by comparison with other stations in the Susquehanna 

River basin. Mean discharge Jan. 6-31 estimated 7,180 second feet. Mean discharge Feb. 1-26 estimated 

6,920 second-feet. Monthly discharge changed slightly to conform with survey computation rules.

SUSQUEHANNA EIVEE AT HAEEISBUEG, PA.

Location. At the Walnut Street Bridge at Harrisburg, 2 miles below the mouth of 

Conodoguiuet Creek and 1J miles above the mouth of Paxton Creek.

Records available. 1890 to December 31, 1912.

Drainage area. 24,000 square mile.

Gage. The original gage established in 1890 by E. Mather, president of the Harrisburg water board, is located in the pump well at the pump house of the city 

waterworks, the well being connected with the river by two large mains. On 

July 18, 1904, a chain gage was installed on the Walnut Street Bridge. The 

data of both gages have remained constant since their establishment.1

Channel. Fairly permanent. The river is divided into two channels by Foster 

Island which is overflowed at flood stages.

Discharge measurements. Made from the bridge. No measurement has been 

made since 1908.

Winter flow. Relation between gage height and discharge affected by ice.

Accuracy. Conditions of flow relatively permanent; a good discharge rating curve 

has been developed.

Cooperation. Complete data for 1912 furnished by the Water Supply Commission 

of Pennsylvania.

CHENANGO RIVER AT BINGHAMTON, N. Y.

Location. At the Court Street Bridge, Binghamton, N. Y., 300 feet below Noyes 

dam, about 2,500 feet above the junction with the Susquehanna, and 14 miles 

below the mouth of Tioughnioga River, coming in from the right.

Records available. July 31,1901, to December 31,1911, and five discharge measurements during 1912. Data also in annual reports of New York State engineer and 

surveyor.

Drainage area. 1,530 square miles.

Gage. Standard chain, fastened to the upstream side of the bridge; datum 

unchanged.

Channel. Bed of river composed of cobble and gravel; fairly permanent. Very 

little vegetation at the bridge except at the sides.

Discharge measurements. Made from the bridge.

Winter flow. As a rule not greatly affected by the presence of ice, although at times 

ice jams form on the control point below the gage.

Diversion. In estimating the run-off of the Chenango River basin the area directly 

tributary to the storage reservoirs from which water is diverted to supply the Erie 

Canal is deducted from the total natural drainage area. The diversion area of 

six reservoirs at the head of Chenango River, whose outflow is turned into the river 

canal through Limestone Creek, is 30 square miles. The diversion area of De 

Ruyter Reservoir at the head of Tioughnioga River, whose outflow is turned into 

Limestone Creek, is 18 square miles. These two drainage areas have been subtracted from the natural drainage area of 1,580 square miles, giving an effective 

area of 1,532 square miles. This estimate is approximate, as no allowance has 

been made for direct inflow to the feeder channels from additional areas nor for 

waste into the original stream. The gross area, from which more or less run-off 

is diverted, is about 105 square miles.

Accuracy. Relation between gage height and discharge at times affected by backwater from Susquehanna River (at high stage) and ice jams on control point. At 

ordinary stages a slight riffle a short distance downstream from the bridge cuts off 

backwater from the Susquehanna.

CHEMUNG RIVER AT CHEMUNG, N. Y

Location. About midway between Chemung, N. Y., and Willawana, Pa., about 

half a mile upstream from the State line, and about 10 miles above the junction 

with the Susquehanna.

Records available. September 7, 1903, to December 31,1912. Data also in annual 

reports of New York State engineer and surveyor.

Drainage area. 2,440 square miles.

Gage. Tape and weight, read twice daily; located at different points, as follows: 

September 7, 1903, to April 19, 1911, on the suspension bridge; April 20, 1911, to 

February 18, 1912, temporarily located about 250 feet upstream from the bridge 

while the bridge was being replaced; February 19 to December 31, 1912, gage on 

the new two-span steel truss bridge, on the site of the old bridge; datum same for 

all locations of the gage.

Channel. Right bank high, clear, and not subject to overflow; left bank of medium 

height, wooded, and overflowed at times of high water. Bed of river composed 

of sand and gravel; clear and fairly permanent.

Discharge measurements. Made from the bridge.

Winter flow. Affected by backwater caused by needle ice.

Artificial control. Largest water-power development on the river is at Elmira, N. Y. 

No dams on the river between Elmira and the mouth of the Chemung.

Accuracy. Conditions for accurate determinations of discharge during the open 

period only fair. Determination of discharge during the winter months liable to 

be considerably in error as a result of backwater caused by needle ice.

NOTE. Relation of gage height to discharge affected by ice Jan. 5 to Feb. 26,1912. There may have been 

some backwater from ice jams during March, 1912. On Apr. 20,1911, the gage was removed from the old 

bridge and installed on the bank of the river about 250 feet above the bridge. On Feb. 19, 1912, it was 

placed on the new bridge at about the same location it had on the old bridge. All gage heights corrected 

so as to be comparable with those taken with the gage in its original position.

NOTE. Daily discharge determined from a well-defined rating curve. Daily discharge for 1911 appears 

to be generally low, for reasons which have not yet been determined. It may be that construction work 

on the new bridge had some temporary effect on the relation of gage height to discharge.

NOTE. Discharge Feb. 8 to Mar. 10,1911, and Jan. 5 to Feb. 26,1912, estimated from chmatologic records 

and comparison with the flow at adj acent stations. Mean discharge Feb. 8 to 28,1911. estimated 1,480 secondfeet. Mean discharge Mar. 1 to 10,1911, estimated 1,170 second-feet. Mean discharge Jan. 4 to 31,1912, 

estimated 660 second feet. Mean discharge Feb. 1 to 26,1912, estimated 1,000 second feet. Discharge for 

1911 appears to be low throughout the year. No definite reason can be assigned for this.
214 SURFACE WATER SUPPLY, 1912, PART I.

. WEST BRANCH OF SUSQUEHANNA EIVER AT WILLIAMSPORT, PA.

Location. At the Market Street Bridge in Williamsport, 2 miles below the mouth

of Lycoming Creek and about 2 miles above the mouth of Loyalsock Creek. 

Records available. March 1, 1895, to December 31, 1912. 

Drainage area. 5,640 square miles.

Gage. Standard chain, fastened to the bridge August 16, 1901; datum unchanged. 

Channel. Permanent. 

Discharge measurements. Made from the bridge or by wading. No measurement

has been made since 1908. 

Artificial control. There is a dam about one-half mile above the station, but the

operation of this dam probably has no effect on the daily gage height. 

Winter flow. Affected by ice. 

Accuracy. Conditions of flow at this point are constant, and a good discharge rating

curve has been developed. 

Cooperation. Complete data for 1912 furnished by the Water Supply Commission

of Pennsylvania.

Daily gage height, in feet,.of West Branch of Susquehanna River at Williamsport, Pa.,

for 1912.

hundred feet below the station, the ledge extending completely across the river

except for one relatively unimportant channel. 

Discharge measurements. Made from the bridge. 

Winter flow. Little affected by ice. 

Canal. The Chesapeake & Ohio Canal parallels the Potomac on the Maryland side.

The average discharge of the canal is 75 to 100 second-feet. This discharge is not

included in the following tables. 

Accuracy. Present discharge rating curve considered very accurate.; should require

relatively little change in the future.

GOOSE CREEK NEAR LEESBURG, VA.

Location. At Evergreen Mills about 7 miles directly south of Leesburg (the most 

convenient railroad station), about 1 mile below the mouth of Little Eiver and 

10 miles above the mouth of Goose Creek.

Records available. July 12, 1909, to December 31, 1912.

Drainage area. 338 square miles.

Qage. Vertical staff, spiked to a tree on the left bank immediately below the tailrace of the mill.

Channel. Fairly permanent.

Discharge measurements. Made between the mill and the dam, either by wading 

or from the highway bridge. The discharge of the mill race is also measured and 

added to the discharge between the mill and the dam.
224 SURFACE WATER SUPPLY, 1912, PART I.

Artificial control. The dam at this point is of timber and rock and at low stages 

most of the water passes through it. The mill race carries water at all times, 

three or four times more when the mill is running than when it is idle. This 

variation in flow causes variation in the gage heights ranging from a few hundred ths to about 0.15 foot; but as the mill is run only four or five hours a day 

the fluctuation has a relatively small effect on the accuracy of estimates.

Daily gage height, in feet, of Goose Creek near Leesburg, Va.,for 1912.

SURFACE WATER SUPPLY, 1912, PART I. 233

RAPPAHANNOCK RIVER BASIN. 

RAPPAHANNOCK RIVER NEAR FREDERICKSBURG, VA.

Location. About 3J miles above Fredericksburg, and about 1J miles above the dam

of the Fredericksburg Power Co.

Records available. September 19, 1907, to December 31, 1912. 

Drainage area. 1,590 square miles. 

Gage. Original gage and station located at a pool a few hundred feet above a rocky

control. This gage was destroyed February 14, 1908, and was replaced February

20, 1908, by a chain gage under the cable. Datum for both gages the same and

unchanged.

Channel. Probably permanent. Current sluggish at extreme low water. 

Discharge measurements. Made from car and cable. 

Winter flow.1 Not often affected by ice. 

Accuracy. Accurate discharge measurements at low stages are difficult. A good

low-water rating curve has been developed. 

Cooperation. Established in cooperation with the Fredericksburg Power Co., by

which the cable and equipment were furnished.

The following discharge measurement was made by J, G. Mathers: 

May 13, 1912: Gage height, 4.97 feet; discharge, 26,700 second-feet.

Daily gage height, in feet, of Rappahannock River near FredericJcsbury, Va.,for 1912.

a Complete ice cover below gage.

6 Distance reference point to water surface. Reference point is cross on top of lower chcrd eyebar, second 

panel from right end of bridge, and 2 feet from right end of bar. Gage at Indian Lake dam read 14.45 feet. 

Discharge from Big Brook was 10 second-feet; discharge from other sources, including leakage through 

dam, was 5 second-feet. Therefore discharge through gates at dam was 507 second-feet. Gate A was open 5 

feet and gate B 3 feet.

c Made in the tail race of the Adirondack Electric Power Corporation near Mechanicville and includes 

only the flow through the wheels of that plant.

SUMMARY OF DISCHARGE PER SQUARE MILE.

The following summary of discharge per square mile is given to 

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

areas in the north Atlantic coast drainage basins. It shows in a general way the seasonal distribution of run-off and the effect of snow, 

ground, surface, and artificial storage; but the most important fact 

worth noting is the almost entire lack of uniformity or agreement 

between any two streams. This indicates that the discharge of each 

stream is a law unto itself, and that all projects dependent upon 

stream flow, if they are to be developed along the safest and most 

economical lines, must be based on records of stream flow collected 

with great care over a long series of years as near the location of 

the project under consideration as possible.
