SLOPE DRAINAGE BASINS, 1926

AUTHORIZATION AND SCOPE OF WORK

This volume is one of a series of 14 reports presenting results of 

measurements of flow made on streams in the United States during 

the year ending September 30, 1926.

The data presented in these reports were collected by the United 

States Geological Survey under the following authority contained in 

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

Provided, That this officer [the Director] shall have the direction of the Geological Survey and the classification of public lands and examination of the geological 

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

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

relating to irrigation. Since the fiscal year ending June 30, 1895, 

successive appropriation bills passed by Congress have carried the 

following items:

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.

In the execution of the work many private and State organizations have cooperated either by furnishing data or by assisting in 

collecting data. Acknowledgments for cooperation of the first kind 

are made in connection with the description of each station affected; 

cooperation of the second kind is acknowledged on pages 10 and 11.

Measurements of stream flow have been made at about 5,250 

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

the Hawaiian Islands. In July, 1924, 1,730 gaging stations were 

being maintained by the Geological Survey and the cooperating 

organizations. Many miscellaneous discharge measurements were

1
2 SURFACE WATER SUPPLY, 1927, PART I

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 water-supply papers from time to time.

DEFINITION OF TERMS

The volume of water flowing in & 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 that represent a rate of flow, as secondfeet, gallons per minute, miner's inches, and discharge in second-feet 

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

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

principal terms used in this series of reports are second-feet, secondfeet per square mile, run-off in inches, and acre-feet. They may be 

defined as follows:

"Second-feet" is an abbreviation for "cubic feet per second." A 

second-foot is the rate of discharge of water flowing in a channel of 

rectangular cross section 1 foot wide and 1 foot deep at an average 

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

unit from which others are computed.

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

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

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

regards time and area.

"Run-off in inches" is the depth to which an area would be covered if all the water flowing from it in a given period were uniformly 

distributed on the surface. It is used for comparing run-off with 

rainfall, which is usually expressed in depth in inches.

An "acre-foot," equivalent to 43,560 cubic feet, 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.

The following terms not in common use are here defined:

"Stage-discharge relation," an abbreviation for the term "relation 

of gage height to discharge."

"Control," a term used to designate the natural section or stretch 

of the channel or artificial structure below the gage which determines 

the stage-discharge relation at the gage. It should be noted that the 

control may not be the same section or sections at all stages.

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

gage the gage height at which water ceases to flow over the control.

EXPLANATION OF DATA

The data presented in this report cover the year beginning October 1, 1925, and ending September 30, 1926. At the beginning "of
EXPLANATION OF DATA 6

January in most parts of the United States much of the precipitation in the preceding three months is stored in the form of snow or 

ice, or in ponds, lakes, and swamps, or as ground water, and this 

stored water passes off in the streams during the spring break-up. At 

the end of September, on the other hand, the only stored water available for run-off is possibly a small quantity in the ground; therefore 

the run-off for the year beginning October 1 is practically all derived 

from precipitation within that year.

The base data collected at gaging stations consist of records of 

stage, measurements of discharge, and general information used to 

supplement the gage heights and discharge measurements in determining the daily flow. The records of stage are obtained either from

FIGURE 1. Typical gaging station

direct readings on a staff gage, chain gage, or from a water-stage 

recorder that gives a continuous record of the fluctuations. Measurements of discharge are made with a current meter. The general 

methods are outlined in standard textbooks on the measurements 

of river discharge. A typical gaging station, equipped with waterstage recorder and measuring cable and car, is shown in Figure 1.

From the discharge measurements rating tables are prepared that 

give the discharge for any stage. The application of the daily gage 

height to these rating tables gives the daily discharge from which 

the monthly and yearly mean discharge is determined.

The data presented for each gaging station in the area covered by 

this report comprise a description of the station, a table giving results 

of discharge measurements, a table showing the daily discharge of 

the stream, and a table of monthly and yearly discharge and run-off.
4 StJEPACE WATEK SUPPLY, 1926, PART I

If the base data are insufficient to determine the daily discharge, 

tables giving daily gage height and results of discharge measurements are published.

The description of the station gives, in addition to statements 

regarding location and equipment, information in regard to any condition that may affect the permanence of the stage-discharge relation, 

covering such subjects as the occurrence of ice, the use of the stream 

for log driving, shifting of control, and the cause and effect of backwater; it gives also information as to diversions that decrease the 

flow at the gage, artificial regulation, maximum and minimum recorded stages, and the accuracy of the records.

The table of daily discharge gives, in general, the discharge in 

second-feet corresponding to the mean of the gage heights read each 

day. At stations on streams subject to sudden or rapid diurnal 

fluctuation the discharge obtained from the rating table and the 

mean daily gage height may not be the true mean discharge for the 

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

mean daily discharge may be obtained by averaging discharge at 

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

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

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

gives the mean flow for the day 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 headed 

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

the mean gage height was lowest. The column headed "Mean" is 

the average flow in cubic feet per second during the month. On this 

average flow computations recorded in the remaining columns, which 

are defined on page 2, are based.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream-flow data depends primarily (1) on the permanence of the stage-discharge relation and (2) on the accuracy of 

observation of stage, measurements of flow, and interpretation of 

records.

A paragraph in the description of the station gives information 

regarding the (1) permanence of the stage-discharge relation, (2) 

precision with which the discharge rating curve is defined, (3) refinement of gage readings, (4) frequency of gage readings, and (5) methods 

of applying daily gage heights to the rating table to obtain the daily 

discharge.
PUBLICATIONS O

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

showing discharge per square mile and run-off in inches may be 

subject to gross errors caused by the inclusion of large noncontributing districts in the measured drainage area, by lack of information concerning water diverted for irrigation or other use, or by 

inability to interpret the effect of artificial regulation of the flow of 

the river above the station. "Second-feet per square mile" and 

"run-off in inches" are therefore not computed if such errors appear 

probable. The computations are also omitted for stations on streams 

draining areas in which the annual rainfall is less than 20 inches. 

All figures representing "second-feet per square mile" and "run-off 

in inches" published by the Geological Survey in earlier reports' 

should be used with caution because of possible inherent but unknown sources of error.

Many gaging stations on streams in the irrigated areas of the 

United States are located above most of the diversions from those 

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

available for further development, as prior appropriations below the 

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

prior appropriations, a paragraph on diversions is presented in each 

station description. The figures given can not be considered exact 

but represent the best information available.

The table of monthly discharge gives only a general idea of the 

flow at the station and should not be used for other than preliminary 

estimates; the tables of daily discharge allow more detailed studies 

of the variation in flow. It should be borne in mind, however, that 

the observations in each succeeding year may be expected to throw 

new light on data previously published.

PUBMICATIONS

Investigation of water resources by the United States Geological 

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

flow of streams and studies of the conditions affecting that flow, but 

it has comprised also investigations of such closely allied subjects as 

irrigation, water storage, water powers, underground waters, and 

quality of waters. Most of the results of these investigations have 

been published in the series of water-supply papers, but some have 

appeared 4n the bulletins, professional papers, monographs, and 

annual reports.

8 SURFACE WATER SUPPLY, 1926, PART I

The records at most of the stations discussed in these reports 

extend over a series of years and miscellaneous measurements at 

many points other than regular gaging stations have been made 

each year. An index of the reports containing records obtained 

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

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

1924. The data for any particular station will be found in the 

reports covering the years during which the station was maintained. 

For example, data from 1902 to 1922 for any station in the area 

-covered by Part III are published in Water-Supply Papers 83, 98, 

128, 169, 205, 243, 263, 283, 303, 323, 353, 383, 403, 433, 453, 473, 

503, 523, and 543, which contain records for the Ohio River Basin 

for those years.

GAGING-STATION RECORDS 

ST. JOHN RIVER BASIN

ST. JOHN RIVER AT TAN BUBEH, ME.

LOCATION. At international bridge at Van Buren, Aroostook County, 14 miles 

above Grand Falls.

DEAINAGE AREA. 8,270 square miles.

RECORDS AVAILABLE. May 4, 1908, to September 30, 1926.

GAGE. Gage painted vertically on second pier from Van Buren end of bridge; 

read by W. H. Scott.

DISCHARGE MEASUREMENTS. Made from bridge.

CHANNEL AND CONTROL. Control practically permanent. Banks high, rocky, 

cleared, and not subject to overflow except at very high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 22.7 feet at 

7.35 a. m. May 19 (discharge, 92,000 second-feet); minimum discharge, 

1,500 second-feet March 20-23 (stage-discharge relation affected by ice). 

1908-1926: Maximum stage recorded, 29.0 feet May 2, 1923 (discharge, 

by extension of rating curve, 134,000 second-feet); minimum discharge 

estimated at 720 second-feet March 18, 1923 (stage-discharge relation 

affected by ice).

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. The little storage that is used for log driving probably does not 

materially affect flow.

ACCURACY. Stage-discharge relation practically permanent except when affected 

by ice. Rating curve well defined. Gage read to tenths once daily, occasionally twice daily. Daily discharge ascertained by applying daily gage 

height to rating table with corrections for effect of ice during winter. Records 

good.

The following discharge measurement was made:

February 18, 1926: Gage height, 3.50 feet; discharge, 2,270 second-feet (stagedischarge relation affected by ice).

Daily discharge, in second-feet, of St. John River at Van Buren, Me., for the year 

ending September SO, 1926

ST. CROIX RIVER BASIN

ST. CEOIX RIVER HEAR BAIIEYVH1E, ME.

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

Grand Falls, Baileyville Township, 3>6 miles east of Baileyville station 

of Maine Central Railroad, Washington County.

DRAINAGE ABEA. 1,320 square miles.

RECORDS AVAILABLE. November 25, 1919, to September 30, 1926.

GAGE. Water-stage recorder on right bank; inspected by employee of St. 

Croix Paper Co.

DISCHARGE MEASUREMENTS. Made from cable.

CHANNEL AND CONTROL. Bed covered with gravel and boulders. Control for 

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

high stages not clearly defined.

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

recorder, 7.20 feet at 8 p. m. May 2 (discharge, 10,100 second-feet); minimum stage, 1.28 feet at noon October 4 (discharge, 470 second-feet).

1919-1926: Maximum stage recorded, 13.90 feet May 1, 1923 (discharge, 

by extension of rating curve, 23,300 second-feet); minimum discharge, 

estimated at 100 second-feet December 9, 1923, July 20 and 27, 1924 (water 

held back by dam).
14 SURFACE WATER SUPPLY, 1926, PART I

ICE. River remains open throughout winter; stage-discharge relation occasionally affected by ice or by logs.

REGULATION. About 30 billion cubic feet of storage has been developedfin 

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

plant a short distance above gage cause fluctuations in stage.

ACCTJKACY. Stage-discharge relation shifts occasionally. Rating curves used 

fairly well defined between 500 and 10,000 second-feet. Operation ^of 

water-stage recorder satisfactory except for short periods as indicatedjin 

footnote to daily-discharge table. Daily discharge ascertained by applying to rating table mean daily gage height as determined by inspection of 

recorder graph, except for days of considerable fluctuation when the average 

of 2-hour intervals were used. Records good.

PENOBSCOT RIVER BASIN

WEST BRANCH OF PENOBSCOT EIVER AT MILIINOCKET, ME.

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

Co., Millinocket, Penobscot County.

DRAINAGE AREA. 1,910 square miles.

RECORDS AVAILABLE. January 11, 1901, to September 30, 1926.

GAGES. Water-stage recorder at Quakish Lake Dam and gages in fore bay and 

tailrace of mill.

CHANNEL AND CONTROL. Crest of concrete dam.

DISCHARGE. Flow computed by considering the flow over the dam, the flow 

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

The wheels were rated at Holyoke, Mass., before being placed in position and 

were tested later by numerous tube-float and current-meter measurements. 

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

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

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

3,500 second-feet, all the water generally flows through the wheels of the 

mill.

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

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

REGULATION. Except for a short time during the high-water period, run-off is 

regulated by storage in North Twin and Ripogenus Lakes, the combined 

capacity of which is about 45 billion cubic feet. Records corrected for 

storage.

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

WEST BRANCH OF PENOBSCOT EIVEE NEAB MEDWAY, ME.

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

of Penobscot River and village of Medway, Penobscot County, and 2 miles 

below East Millinocket.

DRAINAGE AREA. 2,120 square miles.

RECORDS AVAILABLE. February 20, 1916, to September 30, 1926.

GAGE. Water-stage recorder on left bank; inspected by George M. Dow.

DISCHARGE MEASUREMENTS. Made from cable.

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

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

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

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

shifting.

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

recorder, 7.46 feet at 9 p. m. May 23 (discharge, 14,900 second-feet); minimum stage, 1.20 feet 8 a. m. September 19 (discharge, by extension of rating 

curve, 525 second-feet).

1916-1926: Maximum stage recorded, 9.88 feet June 18, 1917 (discharge 

by extension of rating curve, 20,000 second-feet); minimum discharge estimated at 100 second-feet at various times during 1923 and 1924, when water 

was held back by dams.

ICE. Ice forms along both banks, but main channel remains open; stage-discharge 

relation not seriously affected.

REGULATION. Flow at ordinary stages completely regulated by dams and storage 

'reservoirs above station.

ACCURACY. Stage-discharge relation probably shifted slightly at times of high 

water. Rating curve well defined between 1,000 and 8,000 second-feet. 

Daily discharge ascertained by applying to rating table mean daily gage 

height determined by inspection of recorder graph except for days of large 

fluctuations .in stage when the mean of 2-hour intervals was used. Records 

good.

18 SUEFACE WATER SUPPLY, 1926, PAET I

PEHTOBSCOT BIVER AT WEST EHTEIE1D, ME.

LOCATION. At steel highway bridge, 1,000 feet below mouth of Piscataquis 

River and 3 miles west of Enfield railroad station, Penobscot County.

DRAINAGE AREA. 6,600 square miles.

RECORDS AVAILABLE. November 5, 1901, to September 30, 1926.

GAGE. Water-stage recorder on left bank, downstream side of left abutment, 

used since December 11, 1912; inspected by Hai*vey Thompson.

DISCHARGE MEASUREMENTS. Made from bridge.

CHANNEL AND CONTROL. Channel at gage broken by four bridge piers; straight 

above and below gage. Banks high and rocky and not subject to overflow. 

Control is at Passadumkeag Rips, 5 miles below gage.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage recorder, 15.15 feet at 6 a. m. May 5 (discharge, 67,500 second-feet); minimum 

stage, 2.10 feet at 6 a. m. August 16 (discharge, 3,790 second-feet).

1902-1926: Maximum stage recorded, 25.15 feet May 1, 1923 (discharge 

by extension of rating curve, 153,000 second-feet); minimum stage, 1.0 

foot October 29, 1905 (discharge, 1,470 second-feet),

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

discharge ascertained by comparison with records at Sunkhaze Rips collected by Thomas W. Clark.

REGULATION. Flow largely controlled by storage, principally in lakes tributary 

to West Branch. Records not corrected for storage.

ACCURACY. Stage-discharge relation practically permanent except as affected 

by ice and occasionally by logs. Rating curve well defined. Operation of 

water-stage recorder satisfactory. Daily discharge ascertained by applying 

to rating table mean daily gage height taken from recorder graph, except 

for period of ice effect and at times of serious fluctuations in stage when the 

mean of 2-hour periods was used. Records good.

COOPERATION. Gage-height record furnished by Thomas W. Clark, hydraulic 

engineer, Old Town, Me. Occasional discharge measurements made by 

students of the University of Maine under direction of Prof. A. C. Lyon.

The following discharge measurement was made: 

 May 6, 1926: Gage height, 14.30 feet; discharge, 62,700 second-feet.

Daily discharge, in second-feet, of Penobscot River at West Enfield, Me., for the year 

ending September SO, 1926

LOCATION. At Bangor & Aroostook Railroad bridge half a mile south of railroad station at Grindstone, Penobscot County, one-eighth mile above Grindstone Falls, and Q% miles above confluence with West Branch at Medway.

DRAINAGE AREA. 1,070 square miles; includes about 240 square miles of Chamberlain Lake drainage (measured on maps compiled by Maine Water Power 

Commission).

RECORDS AVAILABLE. October 23, 1902, to September 30, 1926.

GAGE. Chain attached to railroad bridge; read by R. D. Porter.

DISCHARGE MEASUREMENTS. Made from railroad bridge or by wading.

CHANNEL AND CONTROL. 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.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 11.16 feet at 

4 p. m. May 4 (discharge, 13,700 second-feet); minimum fetage, 4.30 feet 

August 20 and 21 (discharge, 270 second-feet).

1902-1926: Maximum stage recorded, 16.5 feet April 30, 1923 (discharge, 

by extension of rating curve, 35,100 second-feet); minimum discharge estimated at 30 second-feet February 28, 1904, when stage-discharge relation 

was affected by ice.
20 SURFACE WATER SUPPLY, 1926, PART I

ICE. Ice forms to a considerable thickness at gage and down to head of Grindstone Falls, and although the falls usually remain open during greater part 

of winter, the stage-discharge relation is somewhat affected.

REGULATION. Dams maintained at outlets of a number of lakes and ponds 

near source of river are regulated for log driving; during the summer and fall 

gates are generally left open. The basin of the East Branch since about 

1840 includes about 240 square miles of territory draining into Chamberlain Lake that formerly drained into the St. John River Basin, the diversion 

being made through what is known as Telos Canal. Results not corrected 

for storage and diversions.

ACCURACY. Stage-discharge relation practically permanent except as affected 

by ice and occasionally by logs. Rating curve well defined. Gage read to 

hundredths twice daily, except on Sundays and during winter when it was 

read once a day. Daily discharge ascertained by applying mean daily 

gage height to rating table. Records good.

LOCATION. 1,000 feet below highway bridge and dam at outlet of Sebec Lake, 

Sebec, Piscataquis County.

DBAINAGE ABBA. 344 square miles.

RECORDS AVAILABLE. October 17,, 1924, to September 30, 1926.

GAGS. Water-stage recorder on left bank 1,000 feet below dam at outlet of 

Sebec Lake; inspected by E. W. Ames.

DISCHAHGE MEAStrREMENTs. Made from cable 50 feet below gage or by wading.

CHANNEL AND CONTBOL. Bed covered with gravel and small boulders. Control 

for low and medium stages is well-defined riffle 100 feet below gage; control 

for high stages at head of falls 4 miles below gage.

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

recorder, 7.25 feet at 10 p. m. November 16 (discharge, 3,670 secondfeet); minimum stage, 1.92 feet on several days during October, 1925, and 

September, 1926 (discharge, 106 second-feet).

1924-1926: Maximum stage recorded, that of November 16, 1925; 

minimum stage, 1.36 feet January 25, 1925 (discharge, from extension of 

rating curve, 20 second-feet).

ICE. Stage-discharge relation not affected by ice.

REGULATION. Flow at ordinary stages completely regulated by dams and 

storage reservoirs above station. Records not corrected for storage.

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

between 70 and 3,000 second-feet. Operation of water-stage recorder 

satisfactory except for short periods indicated in footnote to daily-discharge 

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

gage height determined by inspection of recorder sheets, except on days 

when fluctuations were large, the mean of 2-hour periods, or the discharge 

integrator was used. Records good.

The following discharge measurements were made: 

June 3, 1926: Gage height, 3.00 feet; discharge, 541 second-feet. 

June 24, 1926: Gage height, 2.76 feet; discharge, 411 second-feet.

ICE. Stage-discharge relation affected by ice.

REGULATION. Distribution of flow somewhat affected by use of storage reservoirs above station. A small dam and mill half a mile above gage cause 

diurnal fluctuations in stage when mill is in operation, usually from May to 

November.

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

denned below 3,500 second-feet. Operation of water-stage recorded satisfactory throughout year. Daily discharge ascertained by applying to rating 

table mean daily gage height determined by inspection of recorder graphs. 

For days when fluctuation in stage was large the mean discharge of two-hour 

periods was used. Records good.

MOOSEHEAD LAKE AT EAST OUTLET, ME.

LOCATION. At wharf at east outlet of lake at Moosehead, Piscataquis County.

DKAINAGE ABE A. 1,240 square miles.

RECOKDS AVAILABLE. April 1, 1895, to September 30, 1926.

GAGE. Staff at end of boat landing. Two datum planes have been used at east 

outlet. The first, or original datum is 1,011.20 feet above mean sea level 

and about 10 feet below sills of outlet gates; gage is read to this datum.

The second datum, to whi all gage readings published to and including

1911 have been referred, is

REGULATION. The lake is regu 

The dam at the east outlet 

being at elevations varyin

10 feet higher; that is, the zero is at the sill of

the gates. As it is believed that low water may go below the sill of the 

gates (zero of second datum), gage heights since 1912 are published as read; 

that is, to original datum.

.ated to a capacity of 23,735 million cubic feet, 

is controlled by 39 gates, the sills of the gates

from 8.0 feet to 11.4 feet. 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. The records show 

only fluctuations in the level of the lake and are used in the studies of regulation of the lake and in ccmputing the natural flow of Kennebec River at 

The Forks.

KENNEBEC RIVER AT MOOSEHEAD. ME.

LOCATION. At Canadian Pacific Railway bridge one-fourth mile below east outlet dam on Moosehead Lake, half a mile northwest of Moosehead railroad 

station in Big Squaw Mountain Township, Piscataquis County, and 4.4 

miles from Somerset Junction.

DRAINAGE AREA. 1,240 square miles (measured on map compiled by Maine 

Water Power Commission).

RECORDS AVAILABLE. October 1, 1919, to September 30, 1926.

GAGE. Water-stage recorder on west bank 250 feet above railroad bridge installed October 8, 1924; inspected by Frank Haggan. Chain gage on 

bridge used prior to this time at datum about 1.3 feet lower than present

DISCHARGE MEASUREMENTS. Made from bridge.

CHANNEL AND CONTROL. Channel composed of large boulders and gravel. 

Control is a series of rapids; practically'permanent.

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

recorder, 8.88 feet from noon to 10 p. m. November 17 (discharge by extension of rating curve, 12,700 second-feet); minimum stage, 2.23 feet from 

1 p. m. April 23 to 11 p. m. April 24 (discharge by extension of rating curve, 

156 second-feet).

1919-1926: Maximum discharge recorded, 13,400 second-feet (by extension of rating curve) May 12 and 13, 1920; minimum discharge recorded, 

about 62 second-feet April 7-15, 1923.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Leakage through west outlet dam and occasional opening of 

gates in this dam allow some water to pass down the west channel which is 

not included in records of flow at this station.

REGULATION. Discharge is regulated by operation of gates at Moosehead Lake; 

large diurnal fluctuations occur during log-driving season.

34 STJBFACE WATER SUPPLY, 1926, PART I

KENNEBEC RIVEK AT THE FORKS, HE.

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

River at The Forks, Somerset County.

DRAINAGE AREA. 1,570 square miles.

RECORDS AVAILABLE. September 28, 1901, to September 30, 1926.

GAGE. Water-stage recorder on right bank half a mile above highway bridge; 

inspected by S. C. Durgin and S. F. Durgin.

DISCHARGE MEASUREMENTS. Made from bridge.

CHANNEL AND CONTROL. Channel at bridge subject to slight changes; control 

well defined by riffles a short distance below gage.

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

recorder, 8.30 feet at 4 p. m. November 17 (discharge, 15,500 second-feet); 

minimum stage, 2.24 feet at 2 p. m. April 24 (discharge, 766 second-feet).

1901-1926: Maximum stage recorded, 10.1 feet June 18, 1917 (discharge 

by extension of rating curve, 23,700 second-feet); minimum stage, 0.3 foot 

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

ICE. Stage-discharge relation seriously affected by ice.

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

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

a large diurnal fluctuation. Records of monthly discharge have been corrected for storage in Moosehead Lake.

ACCURACY. Stage-discharge relation permanent; affected by ice. Rating curve 

well defined below 10,000 second-feet. Operation of water-stage recorder 

satisfactory throughout year. Daily discharge ascertained by applying to 

rating table mean daily gage height determined by inspection of recorder 

graph, except for the period May 1 to August 9 when discharge integrator 

was used. Records good.

NOTE. The monthly discharge in second-feet per square mile and the run-off in inches do not represent 

the natural flow from the basin because of artificial storage. The yearly discharge and run-off doubtless 

represent more nearly the natural flow, for comparatively little stored water is held over from year to year.

across the river 150 feet below gage. At high stages control is probably at

upper dam at North Anson which is not in use. 

EXTREMES OF DISCHARGE. Maximum stage during period August 23, 1925, to

September 30, 1926, from water-stage recorder, 10.57 feet at 1 p. m. May 3,

1926 (discharge, 8,590 second-feet); minimum stage, 2.18 feet at 8 a. m.

September 15, 1926 (discharge, 25 second-feet).

COBBOSSEECONTEE STREAM AT GARDINER, DIE.

LOCATION. At dam of Gardiner Water Power Co. in Gardiner, Kennebec 

County.

DRAINAGE AEEA. 220 square miles.

RECORDS AVAILABLE. June 16, 1890, to September 30, 1926.

GAGES. Staff in pond above dam and in tailrace of power house. There are 

also gages to indicate water wheels gate and waste gate openings.

DETERMINATION OF DISCHARGE. Discharge determined by considering flow over 

dam, usually nothing except for a short time in spring; flow through two 

gates; flow through 39-inch Victor wheel installed in 1907; flow through 

39-inch Hercules wheel installed in 1895; and leakage. Daily discharge 

 computed from tables based on coefficients and experiments. The accuracy 

of these tables was verified by a series of weir measurements in August, 1921. 

Corrections have been made for leakage.

ICE. Stage-discharge relation not affected by ice.

REGULATION. Numerous lakes in the basin are regulated by dams at the outlets. 

Results npt corrected for storage.

COOPERATION. Computation of daily discharge made by engineers of S. D. 

Warren Co., Cumberland Mills, Me.

Daily discharge, in second-feet, of Cobbosseecontee Stream at Gardiner, Me., for the 

year ending September SO, 1926

44 SURFACE WATER SUPPLY, 1926, PART I

DISCHAEGB. Prior to March, 1904, discharge was determined from records 

of opening of gates in dam; since March, 1904, flow from lake has been recorded by three Alien meters, one on each of three pairs of 30-inch Hercules 

wheels; wheels and recording meters checked by current-meter measurements, brake tests of wheels, and electrical readings of the generator output. 

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

and coefficients determined from current-meter measurements. Water taken 

from Sebago Lake for supply of Portland Water District and water leaking 

through reservoir dam, a total of about 1§ second-feet, not included in tables 

of discharge.

REGULATION. Sebago Lake (area, 46 square miles) is under complete regulation. 

Results not corrected for storage.

COOPERATION. Record in cubic feet per minute furnished by S. D. Warren Co.; 

computations on basis of cubic feet per second made by engineers of the 

Geological Survey.

NOTE. Monthly discharge in second-feet per square mile and run-ofl in inches do not represent the natural 

flow from the basin because of artifical storage. The yearly discharge and run-ofl doubtless represent more 

nearly the natural flow, for comparatively little stored water is held over from year to year.

SACO RIVER BASIN

SACO RIVER AT CORNISH, ME.

LOCATION. At highway bridge at Cornish, York County, half a mile below mouth 

of Ossipee River.

DRAINAGE AREA. 1,300 square miles.

RECORDS AVAILABLE. June 4, 1916, to September 30, 1926.

GAGE. Water-stage recorder on left bank 300 feet above highway bridge; installed October 30, 1919; inspected by A. H. Guimont.

DISCHARGE MEASUREMENTS. Made from bridge.

CHANNEL AND CONTROL. Channel covered with sand and boulders; broken by 

one pier at bridge.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage recorder, 9.49 feet at 7 p. m.May 6 (discharge, 12,600 second-feet); minimum 

stage, 1.23 feet at 7.30 a. m. September 16 (discharge, 205 second-feet; water 

held back by dams).

1916-1926: Maximum stage recorded, 14.72 feet May 2, 1923 (discharge, 

by extension of rating curve, 23,000 second-feet); minimum discharge about 

90 second-feet October 1, 1921 (water held back by dams).

ICE. Ice forms to a considerable thickness; stage-discharge relation seriously 

affected during most winters.

REGULATION. Distribution of flow somewhat affected by power development at 

Great Falls, 3J4 miles above gage.

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

Rating curve well defined above 450 second-feet. Operation of water-stage 

recorder satisfactory. Daily discharge ascertained by applying to rating 

table mean daily gage height as determined by inspection of recorder graphs. 

Discharge for days of large fluctuation is mean of 2-hour periods. Records 

good.

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

Power Commission).

RECORDS AVAILABLE. July 5, 1916, to September 30, 1926.

GAGE. Chain gage attached to bridge; read by O. W. Adams.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Channel covered with sand and gravel; possibly somewhat shifting; broken by one pier at bridge.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.60 feet 

April 26 (discharge, 4,690 second-feet); minimum stage, 0.26 foot at 7 a. m. 

September 23 (discharge, 89 second-feet).

1916-1926: Maximum stage recorded, 8.76 feet April 30, 1923 (discharge, 

by extension of rating curve, 6,740 second-feet); minimum stage, 0.15 foot 

October 18, 1923 (discharge, by extension of rating curve, 66 second-feet).

ICE. Ice forms to considerable thickness and stage-discharge relation is seriously affected during most winters.

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

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

distribution of flow.

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

above 200 second-feet. Gage read to hundredths twice a day. Daily discharge ascertained by applying to rating table mean daily gage height. 

Records good.

SURFACE WATER SUPPLY, 1926, PART I

MERRIMACK RIVER BASIN

PEMIGEWASSET RIVER AT PIYMOUTH, N. H.

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

DRAINAGE AREA. 615 square miles.

RECORDS AVAILABLE. January 1, 1886, to September 30, 1926.

GAGES. Water-stage recorder on right bank; installed September 11, 1926. 

Vertical staff gage in three sections; two lower sections 40 feet above bridge, 

upper section on bridge abutment, about 600 feet above, used prior to that 

date. Staff gage read and recorder inspected by A. F. Morse.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

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

channel covered with fine gravel which shifts occasionally. Control section 

for low stages is gravel bed of river which shifts occasionally. At high 

stages banks are overflowed below bridge and control is somewhat indefinite.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 11.50 feet at 

7 a. m. May 4 (discharge, 14,200 second-feet); minimum stage, 0.29 foot 

at 7 a. m. September 2 (discharge, 84 second-feet).

1903-1926: Maximum stage recorded, 18.17 feet April 29, 1923 (discharge from extension of rating curve, 22,400 second-feet); minimum discharge, 45 second-feet several times during August, September, and October, 

1923.

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

from December to March.

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

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

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

times the ponding of water affects distribution of flow at Plymouth.

ACCURACY. Stage-discharge relation not permanent. Rating curves well defined below 9,000 second-feet and fairly well defined between 9,000 and 

15,000 second-feet. Gage read to half-inches three times a day. Daily 

discharge ascertained by applying rating table to mean of three daily gage 

heights. Records fair.

recorder, 15.12 feet at 3 a. m. April 26 (discharge, by extension of rating 

curve, 20,600 second-feet); minimum stage, 3.49 feet at 6.30 p. m. September 

5 (discharge, 684 second-feet).

1903-1926: Maximum stage recorded, 23.5 feet April 30, 1923 (discharge, 

by extension of rating curve, 41,000 second-feet); minimum discharge, by 

extension of rating curve, 250 second-feet October 4, 1903.

ICE. Stage-discharge relation affected by ice.

REGULATION. Flow affected by storage in Winnepesaukee, Squam, and New 

Found Lakes and by operation of mills above station.

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

Rating curve well defined. Recorder operated satisfactorily except for 

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

ascertained by use of discharge integrator. Records excellent for openwater period and good for period of ice effect.

MERRIMACK RIVER AT LAWRENCE, MASS.

LOCATION. At dam of Essex Co., in Lawrence, Essex County.

DRAINAGE AREA. Total of Merrimack River Basin above Lawrence, 4,663 square 

miles; net drainage area, exclusive of diverted parts of Nashua and Sudbury 

Rivers and Lake Cochituate Basins, 4,452 square miles.

RECORDS AVAILABLE. January 1, 1880, to September 30, 1926.

COMPUTATIONS OP DISCHARGE. Accurate record is kept of_ the flow over the 

dam and through the various wheels and gates. This flow includes the 

water wasted into the Merrimack from the Nashua, Sudbury, and Cochituate drainage basins. Estimates of the quantities wasted from these basins 

are furnished by the Metropolitan Water & Sewerage Board of Boston and 

subtracted from the quantity measured at Lawrence to obtain the net flow 

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

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

at gage slightly. There are several small storage ponds between Contoocook Pond and the gage, but these do not affect the flow.

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

Rating curve well denned below 50 second-feet and poorly denned above. 

Slope gage read to hundredths twice daily. Daily discharge ascertained by 

applying mean daily gage height to rating table. Records fair.

SOUHEGAN EIVEK AT MERKIMACK, H. H.

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

and \}i miles above confluence with Merrimack River, Hillsb,orough County.

DRAINAGE AREA. 168 square miles.

RECORDS AVAILABLE. July 13, 1909, to September 30, 1926.

GAGE. Water-stage recorder on left bank 350 feet above falls installed October 

15, 1913; inspected by employee of W. H. McElwain Co.

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

cable at high stages.

CHANNEL AND CONTROL. Channel opposite gage is pool in which velocity is 

very low. Control of this pool is rock ledge at head of Atherton Falls and 

is permanent.

ICE. Ice forms on control for short periods during some winters.

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

recorder, 6.93 feet at noon December 5 (discharge, 2,590 second-feet); minimum discharge, 13 second-feet from 11 a. m. to 5 p. m. September 9.

1909-1926: Maximum stage recorded, 11.82 feet April 8, 1924 (discharge 

by extension of rating curve, 7,120 second-feet); minimum discharge, that of 

September 9, 1926.

REGULATION. Flow slightly affected by operation of mills at Milford, 8 miles 

above.

ACCURACY. Stage-discharge relation permanent; not affected by ice. Rating 

curve well defined below 2,000 second-feet and extended above. Operation 

of recorder satisfactory except as noted in footnote to daily-discharge table. 

Daily discharge ascertained by applying mean daily gage height to rating 

table. Records excellent.

The following discharge measurements were made:

October 8, 1925: Gage height, 2.26 feet; discharge, 40.8 second-feet.

August 19, 1926: Gage height, 2.06 feet; discharge, 21.5 second-feet.

SOUTH BRANCH OF NASHUA RIVER BASIN NEAR CLINTON, MASS.

LOCATION. At Wachusett Dam, near Clinton, Worcester County.

DRAINAGE AREA. 119 square miles 1896-1907; 118.19 square miles 1908-1913;

108.84 square miles 1914-1926. 

RECORDS AVAILABLE. July, 1896, to September, 1926.
64 SURFACE WATER SUPPLY, 1926, PART I

REGULATION. Flow affected by storage in Wachusett Reservoir and other 

ponds. Beginning with 1897, the determinations of discharge have been 

corrected for gain or Iocs in the reservoir and ponds, so that the record 

shows approximately the natuial flow of the stream.

The yield per square mile is the'yield of the drainage area including the 

water surfaces. For the years 1896 to 1902, inclusive, the water surface 

amounted to 2.2 per cent of the total area; 1903, 2.4 per cent; 1904, 3.6 

per cent; 1905, 4.1 per cent; 1906, 5.1 per cent; 1907, 6.0 per cent; 1908 

and subsequent years, 7.0 per cent.

COOPERATION. Record furnished by the water division of the Metropolitan 

District Commission; rearranged in form of climatic year by engineers of 

the Geological Survey.

SUDBURY RIVER AND LAKE COCHITUATE BASINS NEAR FRAMINQHAM AND COCHITUATE, MASS

DRAINAGE AREA. Area of Sudbury Basin from 1875 to 1878, inclusive, was 

77.8 square miles; 1879-80, 78.2 square miles; 1881-1926, 75.2 square miles. 

Area of Cochituate Basin from 1863 to 1909, inclusive, was 18.87 square 

miles; 1910, 17.8 square miles; and 1911-1926, 17.58 square miles.

RECORDS AVAILABLE. Of Sudbury River, January, 1875, to September, 1926; 

of Lake Cochituate, January, 1863, to September, 1926. Records of rainfall have been kept in the Sudbury Basin since 1875 and in the Cochituate 

Basin since 1852, but the accuracy of the latter is considered doubtful 

previous to 1872.

REGULATION. The greater part of the flow from these basins is controlled by 

storage reservoirs operated by the Metropolitan Water and Sewerage Board. 

Lake Cochituate, which drains into Sudbury River a short distance below 

Framingham, is controlled as a storage reservoir for the Metropolitan 

waterworks system. In the Sudbury River Basin the water surfaces exposed 

to evaporation have been increased from time to time by the construction 

of additional storage reservoirs. From 1875 to 1878, inclusive, the watei 

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

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

and subsequent years, 6.5 per cent.
MERRIMACK RIVER BASIN

DETERMINATION OF DISCHARGE. In determining the run-off of the Sudbury 

and Cochituate drainage areas the water diverted for the municipal supply 

of Framingham, Natick, and Westboro, which discharge their sewage 

outside the basins, is taken into consideration; the results, however, are 

probably less accurate since the sewage diversion works were constructed. 

Water from the Wachusett drainage basin also passes into the reservoirs 

in the Sudbury Basin and must be measured to determine the yield of the 

Sudbury Basin; the small errors unavoidable in the measurement of large 

quantities of water decrease the accuracy of the determination of the Sudbury water supply during the. months of low yield for years subsequent 

to 1897.

COOPERATION. Records furnished by the water division of the Metropolitan 

District Commission; rearranged in form of climatic year by engineers of 

the Geological Survey.

66 SURFACE WATER SUPPLY, 1926, PART I

PROVIDENCE RIVER BASIN

BLACKSTONE RIVER AT WORCESTER, MASS.

LOCATION. 150 feet below highway bridge on Webster Street, Worcester, 

Worcester County, three-quarters of a mile above mouth of Tatnuck Brook 

and 1 mile below Kettle Brook.

DKAINAGE AREA. 31.5 square miles, including 6.3 square miles from which water 

is diverted to water-supply system of Worcester (measured on topographic 

maps).

RECORDS AVAILABLE. August 14, 1923, to September 30, 1926.

GAGE. Water-stage recorder on right bank; inspected by H. C. Merritt.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Channel smooth, subject to growth x>f aquatic vegetation during summer. Control for low stages at riffles 200 feet below gage; 

at high stages control is in vicinity of railroad bridge, half a mile below gage.

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

recorder, 3.60 feet at 12.30 p. m. March 25 (discharge, 400 second-feet); 

minimum stage, 0.35 foot from 2 a. m. to 2 p. m. September 25 (discharge, 

4.8 second-feet).

1924-1926: Maximum discharge recorded, 740 second-feet April 7, 1924; 

minimum discharge, 2.2 second-feet October 13, 1924, and August 5, 1925.

ICE. At times of very low temperature ice forms along banks of river; stagedischarge relation not affected.

DIVERSIONS. Water is diverted from 7.0 square miles as a part of the water 

supply of Worcester. During low and medium stages practically the entire 

flow from this area is diverted.

REGULATION. Operation of several storage reservoirs above gage affects distribution of flow; diurnal variation in stage is also caused by operation of 

small mill 200 feet above gage.

ACCURACY. Stage-discharge relation not permanent. Rating curve well defined 

below and fairly well above 20 second-feet. Operation of water-stage 

recorder satisfactory except for periods indicated in footnote to dailydischarge^table. Water diverted into the water-supply system of Worcester 

is measured by Venturi meters. Table of daily discharge shows flow past 

gage without correction for diversion. Daily discharge ascertained by applying mean daily gage height by inspection to rating table. Records good.

THAMES RIVER BASIN

QUINEBAUG KIVER AT JEWETT CITY, CONN.

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

from Slater Mills (mouth of Pachaug River); Jewett City, town of Griswold, 

New London County.

DKAINAGE ABBA. 712 square miles (measured on topographic maps).

RECOBDS AVAILABLE. July 17, 1918, to September 30, 1926.

GAGE. Water-stage recorder on left bank; inspected by Theodore Da vis.
68

DISCHARGE MEASUREMENTS. Made from cable.

CHANNEL AND CONTROL. Channel of gravel and alluvial deposits. Control for 

low stages is fairly well defined riffle a few hundred feet below gage, at high 

stages control is at head of rapids 2% miles below gage.

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

recorder, 11.67 feet sometime during period March 6-10 (discharge, 5,620 

second-feet); minimum stage, 3.58 feet at 10 a. m. September 25 (discharge, 

41 second-feet; water held back by dams).

1918-1926: Maximum stage, about 16.3 feet during high water March 

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

minimum discharge, 30 second-feet August 23, 1919 (water held back by 

dams).

ICE. Stage-discharge relation not affected by ice.

REGULATION. Flow of Pachaug River, which drains 59.7 square miles and enters 

Quinebaug River through the canal 570 feet above gage, is under almost 

complete regulation. Numerous small reservoirs and power developments 

on the main river and tributaries above station also affect distribution of flow. 

Operation of mills at Jewett City causes a large variation in discharge.

ACCURACY. Stage-discharge relation practically permanent; unaffected by ice. 

Rating curve well defined above 200 second-feet. Operation of water-stage 

recorder satisfactory except for periods indicated in footnote to dailydischarge table. Daily discharge ascertained by use of discharge integrator. 

Records good.

The following discharge measurements were made: 

October 14, 1925: Gage height, 5.97 feet; discharge, 826 second-feet. 

May 29, 1926: Gage height, 7.36 feet; discharge, 1,720 second-feet. 

July 28, 1926: Gage height, 4.85 feet; discharge, 309 second-feet.

CONNECTICUT RIVER AT FIRST CONNECTICUT LAKE, NEAR PITTSBURG, N. H.

* ;

LOCATION. At outlet of First Connecticut Lake, 6 miles northeast of Pittsburg, 

Coos County. *

DRAINAGE AREA. 81.4 square miles.

RECORDS AVAILABLE. April 1, 1917, to September 30, 1926.

GAGE. Water-stage recorder on right bank one-fourth mile below outlet dam; 

inspected by H. H. Young.

DISCHARGE MEASUREMENTS. Made from cable 200 feet above gage, from highway bridge 3 miles below, or by wading.

CHANNEL AND CONTROL. -Bed rough, with rock bottom; channel at cable section has been improved by removal of rocks and ledges. Control for river 

gage is rock ledge extending completely across stream; 3 feet of fall immediately below ledge.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage recorder, 3.73 feet at 3 p. m. March 14 (discharge, about 1,220 second-feet; 

water being released from storage); minimum discharge, 7 second-feet April 

14 and 15 (gates closed at dam).

1917-1926: Maximum discharge recorded, about 3,870 second-feet May 

5, 1925 (water being released from storage); minimum discharge during 

period 3 second-feet during several days in April, 1917 (gates closed at dam).

ICE. Stage-discharge relation occasionally slightly affected by ice.

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

ponds above gage; records of monthly discharge have been corrected for 

effect of storage in First Lake since April, 1917, and for effect of storage in 

Second Lake since October, 1919.

ACCURACY. Stage-discharge relation permanent; not affected by ice. Rating 

curve fairly well defined below 800 second-feet. Operation of water-stage 

recorder satisfactory except as noted in footnote to daily-discharge table. 

Daily discharge ascertained by applying mean daily gage height to rating 

table, except on days of considerable fluctuation when discharge for portions 

of days were weighted to obtain mean. Records good.

The following discharge measurement was made:

September 4, 1926: Gage height, 3.28 feet; discharge, 871 second-feet.

CONNECTICUT RIVER BASIN 73

* CONNECTICUT EIVEB AT SOUTH NEWBUBY, VT.

LOCATION. At covered highway bridge between South Newbury, Orleans

County, Vt., and Haverhill, Grafton County, N. H., half a mile below

Oliverian Brook, and 4 miles above mouth of Waits River 

DRAINAGE AREA. 2,830 square miles. 

RECORDS AVAILABLE. July 22, 1918, to December 20, 1921, and August 19,

1922, to September 30, 1926. 

GAGE. Chain gage on downstream side of bridge; read by Mrs. M. W. Dickey.

Datum is 8.8 feet higher than datum of gage at Orford. 

DISCHARGE MEASUREMENTS. Made from downstream side of highway bridge

\% miles above gage.

CHANNEL AND CONTROL. Channel wide and deep, with gravelly bottom. Control not clearly denned, except that several distinct riffles appear between

South Newbury and Orford. 

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 26.90 feet at

6 p. m. May 5 (discharge, by extension of rating curve, 37,200 second-feet);

minimum stage, 0.50 foot at 8 a. m. August 23 (discharge, 540 second-feet). 

1918-1926: Maximum stage recorded, 30.65 feet May 1, 1923 (discharge,

by extension of rating curve, 43,600 second-feet); minimum stage 0.30' foot

September 24, 1921 (discharge, 460 second-feet). 

ICE. Stage-discharge relation affected by ice, usually from December to March;

ice cover generally remains in place throughout winter. 

REGULATION. About 4,100 million cubic feet of storage has been developed at

First and Second Connecticut Lakes and tributary streams above Pittsburg.

There are several power developments above station, but their operation

does not seriously affect distributipn of flow. 

ACCURACT. Stage-discharge relation permanent except when affected by ice.

Rating curve well defined below 28,000 second-feet and extended above.

Gage read to hundredths twice daily. Daily discharge ascertained by

applying mean daily gage height to rating table with correction for effect of

ice during winter. Records good during open-water period and fair for

periods affected by ice.

The following discharge measurements were made:

January 30, 1926: Gage height, 3.94 feet; discharge, 1,570 second-feet (stage 

discharge relation affected by ice).

May 21, 1926: Gage height, 10.03 feet; discharge, 10,300, second-feet. 

September 15, 1926: Gage height, 2.44 feet; discharge, 1,840 second-feet.

Daily discharge, in second-feet, of Connecticut River at South Newbury, Vt., for the 

year ending September SO, 1926

CONNECTICUT EIVEE AT WHITE EIVEE JUNCTION, VT.

LOCATION. At railroad bridge between Westboro, Lebanon Township, Grafton 

County, N. H., and White Rivei Junction, Hartford Township, Windsor 

County, Vt. Mascoma River enters from east 1 mile below gage.

DRAINAGE AREA. 4,120 square miles.

RECORDS AVAILABLE. November 1, 1911, to September 30, 1926.

GAGE. Chain gage over west channel installed June 16, 1918; read by F. H. 

Chipman.

DISCHARGE MEASUREMENTS. Made at highway bridges one-fourth mile above 

gage, the flow in White River and in Connecticut Rivei above confluence of 

two streams being measured separately, the sum of the two being the discharge at gage.
CONNECTICUT RIVER BASIN 75

CHANNEL, AND CONTROL. Channel deep, bed covered with alluvial deposits, 

gravel, and rock ledge; control formed by rock outcrop extending across the 

river at several places below gage; control for high water is probably at 

Quechee Falls, 7 miles downstream.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 20.4 feet at 

4 p. m. April 25 (discharge, 57,100 second-feet); minimum stage, 3.2 feet at 

8 a. m. August 22 (discharge, 820 second-feet).

1912-1926: Maximum stage recorded, 30.0 feet at 9 p. m. Maich 27, 1913 

(discharge, by logarithmic extension of rating curve, 113,000 second-feet); 

minimum stage, 2.8 feet September 8, 1913 (discharge, 560 second-feet).

ICE. River covered with ice each winter, usually from December to March; 

stage-discharge relation seriously affected.

REGULATION. Distribution of flow not seriously affected by power plants, except 

for low water on Sundays caused by Sunday shutdown of paper mill at 

Wilder, 2 miles above gage. About 4,100 million cubic feet of storage at 

Connecticut Lakes and tributary streams above Pittsburg, N. H., has some 

effect on low-water discharge.

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

Rating curve well defined. Gage read to tenths twice daily. Daily discharge ascertained by applying mean daily gage height to rating table, with 

correction for effect of ice during winter. Records good for open-water 

period and fair foi periods affected by ice.

COOPERATION. Gage-height record furnished by New England Power Co.

The following discharge measurements were made:

February 1, 1926: Gage height, 8.18 feet; discharge, 3,990 second-feet.

May 22, 1926: Gage height, 9.15 feet; discharge, 12,300 second-feet.

Daily discharge, in second-feet, of Connecticut River at White River Junction, Vt., 

for the year ending September SO, 1926 ,

CONNECTICUT RIVER AT SUNDERIAND, MASS.

LOCATION. At five-span steel highway bridge at Sunderland, Franklin County, 

on road leading to South Deerfield, 18 miles in direct line and 24 miles by 

river above dam at Holyoke. Deerfield River enters from west 8 miles 

above station.

DRAINAGE AREA. 8,000 square miles.

RECORDS AVAILABLE. March 31, 1904, to September 30, 1926.

GAGE. Water-stage recorder on left bank, near downstream side of bridge; 

inspected by P. J. Hogan.

DISCHARGE MEASUREMENTS. Made from highway bridge.

CHANNEL AND CONTROL. Channel deep, with bottom of coarse gravel and 

alluvial deposits. Control at low stages not well defined but practically 

permanent. At high stages the control is at crest of dam at Holyoke.

EXTREMES OF DISCHARGE; Maximum stage during year, from water-stage 

recorder, 24.90 feet at 1.30 p. m. April 26 (discharge, 83,700 second-feet); 

minimum stage, 0.08 foot at 6 a. m. September 27 (discharge, 490 secondfeet).

1904-1926: Maximum stage recorded, 30.7 feet during night of March 

28, 1913, determined by leveling from floodmarks (revised discharge, by 

extension of rating curve, 135,000 second-feet); minimum stage, 0.0 foot 

August 29, 1921 (discharge, by extension of rating curve, 450 second-feet).

ICE. River usually freezes over early in winter, but ice is likely to break up at 

times of sudden rises in stage and at those times it occasionally forms ice 

jams at Northampton, 10 miles below station causing several feet of backwater at gage.

REGULATION. Distribution of flow affected by operation of power plants at 

Turners Falls, and by regulation of Deerfield River (see Deerfield River at 

Charlemont, Mass.). Effect of regulation is shown by low water at gage on 

Sundays and Mondays. Records of monthly discharge corrected for 

storage in First and Second Connecticut Lakes and in Somerset and Davis 

Bridge Reservoirs.
CONNECTICUT RIVER BASIN 77

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

Eating curve well defined below 75,000 second-feet. Chain gage read to 

hundredths twice daily. Operation of recorder satisfactory except foi 

period as noted in footnote to daily-discharge table. Owing to partly clogged 

intake pipe mean daily gage height as determined from recorder graph by 

inspection was corrected by amount as determined from chain gage readings. 

Daily discharge ascertained by applying corrected mean daily gage height to 

rating table, with corrections for effect of ice during winter. Records fair 

for open-water conditions; during ice period, subject to error.

.The following discharge measurements were made:

April 13, 1926: Gage height, 12.44 feet; discharge, 34,100 second-feet.

July 17, 1926: Gage height, 5.86 feet; discharge, 9,840 second-feet.

Daily discharge, in second-feet, of Connecticut River at Sunderland, Mass., for the 

year ending September 30, 1926

WHITE RIVEB AT WEST HARTFORD, VT.

LOCATION. 500 feet above highway bridge in West Hartford, Windsor County, 

7 miles above mouth of river.

DRAINAGE AREA. 687 square miles.

RECORDS AVAILABLE. June 9, 1915, to September 30, 1926.

GAGE Inclined staff on left bank; read by F. P. Morse.

DISCHARGE MEASUREMENTS. Made by wading.

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

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

by rock ledge 100 feet below gage; well defined.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 13.20 feet 

at 7 a. m. April 25 (discharge, 16,700 second-feet); minimum stage, 2.78 

feet at 6 p. m. September 22 (discharge, 126 second-feet).

1915-1926: Maximum stage recorded, 16.9 feet April 12, 1922 (discharge 

by extension of rating curve, 24,500 second-feet); minimum stage, 2.05 feet 

June 27, 1923 (discharge, 19 second-feet).

The high water of March 27,1913, reached a stage of 18.9 feet as determined 

from reference point on scale platform opposite gage (discharge, about 

30,000 second-feet).

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

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

REGULATION. There are several power plants on the main stream and tributaries above station, the nearest being that of Vermont Copper Co. at 

Sharon. When this plant is in operation it causes some diurnal fluctuation 

in discharge at low stages. The effect of power, plants farther upstream is

, practically eliminated by the large amount of pondage at Sharon.

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

Rating curve well defined. Gage read to hundredths twice daily. Daily 

discharge determined by applying mean daily gage height to rating table. 

Records good for open-water period; fair for ice period.
CONNECTICUT RIVER BASIN 79

The following discharge measurements were made:

January 31, 1926: Gage height, 4.36 feet; discharge, 611 second-feet (stagedischarge relation affected by ice).

September 14, 1926: Gage height, 3.01 feet; discharge, 160 second-feet. 

September 14, 1926: Gage height, 3.11 feet; discharge, 201 second-feet.

MASCOMA RIVER AT MASCOMA, N. H.

LOCATION. 250 feet below railroad bridge and 1,500 feet below outlet of Mascoma Lake, in Mascoma, Grafton County.

DRAINAGE AREA. 148 square miles (measured on Walker map).

RECORDS AVAILABLE. August 16, 1923, to September 30, 1926.

GAGE. Water-stage recorder on left bank; inspected by Frances Greeley.

DISCHARGE MEASUREMENTS. Made from railroad bridge or by wading.

CHANNEL AND CONTROL. Channel opposite gage is pool in which velocity is very 

low. Control well denned at head of rapids 200 feet below gage.

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

recorder, 5.57 feet at noon April 26 (discharge, by extension of rating curve, 

2,680 second-feet); minimum stage, 1.15 feet at 4 a. m. and noon September 

6 (discharge, by extension of rating curve, 2.4 second-feet).

1923-1926: Maximum stage recorded, 6.25 feet March 30, 1925 (discharge, 

by extension of rating curve, 3,700 second-feet; minimum stage, 1.03 feet 

June 28, 1925 (discharge, 1.2 second-feet).

ICE. Stage-discharge relation not affected by ice.

REGULATION. Operation of gates in storage dam 1,500 feet above gage causes 

considerable fluctuation in discharge during ordinary stages. About 1.5 

billion cubic feet of storage has been developed in ponds and lakes in drainage 

basins above gage.

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

below 1,700 second-feet. Operation of water-stage recorder satisfactory. 

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

or using weighted mean discharge for days when variation occurred from, 

opening and closing gates at dam. Records excellent.

The following discharge measurements were made:

February 1, 1926: Gage height, 2.33 feet; discharge, 148 second-feet.

May 24, 1926: Gage height, 2.44 feet; discharge, 168 second-feet.

ASHUELOT RIVER NEAR GILSUM, N. H.

LOCATION. At stone-arch highway bridge on Keene-Newport road, 1 mile belowGilsum and 8 miles north of Keene, Cheshire County.

DRAINAGE AREA. 68.5 square miles (measured on Hitchcock map).

RECORDS AVAILABLE. August 18, 1922, to September 30, 1926.

GAGE. Water-stage recorder on right bank 60 feet above bridge; inspected by 

employee of Keene Gas & Electric Co.

DISCHARGE MEASUREMENTS. Made by wading or from highway bridge.

CHANNEL AND CONTROL. Channel rough with steep slope. Control formed by 

rocks and boulders near gage.

EXTREMES OP DISCHARGE. Maximum stage during year, from water-stage recorder, 8.33 feet at 10.30 a. m. April 25 (discharge, 1,490 second-feet); 

minimum stage, 1.17 feet at 5 a. m. July 3 (discharge, 5.4 second-feet).

1922-1926: Maximum stage recorded, that of April 25, 1926; minimum 

discharge about 1 second-foot October 6, 1922, and July 10, 1923 (water 

held back by dam).

ICE. Ice forms on rocks and along banks, occasionally affecting stage-discharge 

relation.

REGULATION. Flow affected by operation of mills at Gilsum. Several lakes and 

ponds above gage provide opportunity for storage, but little if any utilization of these possibilities has been made.

ACCURACY. Stage-discharge relation changed, probably during high water April 

25. Rating curves well defined below 70 second-feet and fairly well defined 

from 70 to 1,000 second-feet. Operation of water-stage recorder satisfactory. 

Daily discharge ascertained by applying mean daily gage height to rating 

table with correction for effect of ice during winter. Records good.

CONNECTICUT RIVER BASIN 83

ASHUELOT RIVER AT HINSDAIE, N. H.

LOCATION. At lower steel highway bridge a quarter of a mile below dam of

Fisk Paper Co. and \% miles above mouth of river at Hinsdale, Cheshire

County.

DRAINAGE AREA. 440 square miles. 

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

1914, to September 30, 1926.

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

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading. 

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

Control is a short distance below gage; practically permanent. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.79 feet at

4 p. m. April 26 (discharge, 4,140 second-feet); minimum stage, 2.02 feet at

8 a. m. August 30 (discharge, 11 second-feet).

1914-1926: Maximum stage recorded, 9.98 feet March 29, 1920 (discharge by extension of rating curve, 8,940 second-feet); minimum stage,

1.87 feet August 12, 1923 (discharge, 5 second-feet). 

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

short periods. 

REGULATION. The mills immediately above station are operated continuously

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

reservoirs and ponds on river and tributaries have some effect on distribution

of flow. 

ACCURACY. Stage-discharge relation probably permanent except when affected

by ice. Rating curve well defined. Gage read to hundredths twice daily.

Daily discharge ascertained by applying mean daily gage height to rating

table. Records fair.

The following discharge measurements were made:

January 24, 1926: Gage height, 3.99 feet; discharge, 611 second-feet (stagedischarge relation affected by ice).

May 25, 1926: Gage height, 3.53 feet; discharge, 354 second-feet. 

September 22, 1926: Gage height, 2.90 feet; discharge, 112 second-feet.

REGULATION. Two small mills above gage, the nearest at East Sullivan, 3 miles 

upstream, cause slight diurnal fluctuation in discharge. Several lakes and 

ponds above gage provide opportunity for storage, but little if any utilization has been made of these possibilities.

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

Rating curve well denned. Operation of recorder satisfactory except as noted 

under footnote to daily-discharge table. Daily discharge ascertained by 

applying mean daily gage height to rating table. Records good except for 

estimated period and when stage-discharge relation was affected by ice, for 

which they are subject to considerable error.

The following discharge measurements were made:

January 25, 1926: Gage height, 4.79 feet, 33.3 second-feet (stage-discharge 

relation affected by ice.)

April 29, 1926: Gage height, 3.60 feet, 242 second-feet. 

May 25, 1926: Gage height, 2.57 feet, 33.3 second-feet.

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

LOCATION. At highway bridge on State road between Keene and Troy, onefourth mile from Webb railroad station, Marlboro, Cheshire County.

DBAINAGE AREA. 36.6 square miles.

RECOBDS AVAILABLE. November 16, 1920, to September 30, 1926.

GAGE. Water-stage recorder on right bank; inspected by W. L. Goodell.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

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

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

permanent

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

recorder, 4.02 feet at 3 p. m. April 25 (discharge, 565 second-feet); minimum 

discharge, 0.4 second-foot September 15-17.

1920-1926: Maximum stage recorded, 5.53 feet February 12, 1925 (discharge, about 1,150 second-feet); minimum discharge, that of September, 

1926.

ICE. Stage-discharge relation affected by ice.

REGULATION. Distribution of flow affected by operation of mills at Troy, 4 miles 

upstream; several small storage ponds on main stream and tributaries 

above gage.

ACCURACY. Stage-discharge relation not permanent. Rating curves well defined 

below 200 second-feet and fairly well defined between 200 and 500 second-feet. 

Operation of water-stage recorder satisfactory except for periods indicated 

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

discharge integrator, with correction for effect of ice during winter, except 

where mean gage height could be obtained accurately by inspection and for 

period January 28 to March 7, when discharge was estimated. Records good 

for open-water period and poor for winter.

88 SURFACE WATER SUPPLY, 1926, PART I

MILLERS RIVER NEAR WINCHENDON, MASS.

LOCATION. At steel highway bridge known as Nolans Bridge, half a mile below 

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

County.

DRAINAGE AREA. 80.0 square miles. 

RECORDS AVAILABLE. June 5, 1916, to September 30, 1926.

GAGE. Water-stage recorder on right bank below highway bridge; inspected by 

Robert Sawyer.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Channel covered with gravel and alluvial deposits. 

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

EXTREMES OP DISCHARGE. Maximum stage during year, from water-stage recorder, 7.37 feet at 4.45 p. m. April 26 (discharge, 902 second-feet); minimum discharge, 10 second-feet September 16-20 (water held back by dams). 

1916-1926: Maximum discharge recorded, about 1,280 second-feet June 

25, 1922; minimum discharge recorded, practically zero at 5 a. m. September 20, 1918, and at 9 p. m. January 14, 1925 (water held back by dams).

ICE. Ice cover usually forms during the winter and, owing to large diurnal 

fluctuation caused by operation of power plants near Winchendon, water frequently overflows ice.

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

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

reservoirs.

ACCURACY. Stage-discharge relation not permanent. Rating curves fairly well 

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

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

by applying mean daily gage height to rating table or by discharge integrator 

with corrections for effect of ice during winter. Records good for open-water 

periods when water-stage recorder was in operation and fair for other times.

DEERFIE1D RIVER AT CHARIEMONT, MASS.

LOCATION. 1 mile below Charlemont, Franklin County.

DRAINAGE AREA. 362 square miles.

RECORDS AVAILABLE. June 19, 1913, to September 30, 1926.

GAGE. Water-stage recorder on left bank; inspected by E. F. Spear.

DISCHARGE MEASUREMENTS. Made from cable or by wading.

CHANNEL AND CONTROL. Channel of coarse gravel and boulders; fairly uniform 

section; control practically permanent. >

'EXTREMES OF DISCHARGE. Maximum stage during year from water-stage recorder, 6.87 feet at 3.30 a. m. April 25 (discharge, 7,980 second-feet; 

water held back by storage reservoirs); minimum stage, 1.51 feet at noon 

September 13 (discharge, 50 second-feet; water held back by dams at power 

stations above gage).

1913-1926: Maximum stage recorded, 15.7 feet-July 8, 1915 (discharge 

by extension of rating curve, 45,000 second-feet); minimum stage, 0.70 foot 

June 17, 1921 (practically no flow; water held back by dams).

ICE. Since extensive regulation on river, stage-discharge relation seldom affected

: by ice.

REGULATION. Flow regulated by storage reservoirs at Somerset and Whitingham, Vt. Several power plants above station cause diurnal fluctuation.

ACCURACY. Stage-discharge relation changed slightly during high water in 

April; not affected by ice. Rating curve well defined. Operation of waterstage recorder satisfactory except as noted in footnote to daily-discharge 

table. Daily discharge ascertained from recorder graph by means of discharge integrator. Records excellent except for estimated periods, for 

which they are fair.

The following discharge measurements were made:

January 19, 1926: Gage height, 3.61 feet; discharge, 1,520 second-feet.

July 16, 1926: Gage height, 3.31 feet; discharge, 1,220 second-feet.

stage, 1.27 feet from 5 a. m. to 11 a. m. September 20 (discharge, 15 secondfeet).

1912-1926: Maximum stage recorded, 6.25 feet April 8, 1924 (discharge, 

2,950 second-feet); minimum discharge, 5 second-feet October 26, 1914 

(water held back by dams).

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

ice during most winters.

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

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

and a low discharge on Sundays and holidays.

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

Rating curve well defined. Operation of water-stage recorder satisfactory 

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

discharge ascertained by use of discharge integrator with corrections for 

effect of ice during winter. Records good for open-water period and fair 

for ice period.

in channel during summer. Control shifts slightly at various times; at 

high stages control is probably at dam at Bondsville, 4 miles below gage.
CONNECTICUT RIVEB BASIN 101

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

6.03 feet at 10 p. m. April 11 (discharge, 1,250 second-feet); minimum stage, 

1.91 feet from 8 p. m. September 24 to 8 p. m. September 25 (discharge^ 

52 second-feet). -

1910-1926: Maximum stage recorded, 9.08 feet April 7, 1923 (discharge,- 

2,390 second-feet); minimum discharge, 22 second-feet September 22, 1914.

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

during most winters.

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

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

during present year.

ACCURACY. Stage-discharge relation not permanent. Rating curves fairly well 

defined. Water-stage recorder operated satisfactorily except for periodsindicated in footnote to daily-discharge table. Daily discharge ascertained 

by applying mean daily gage height to rating table, with corrections for iceeffect during winter. Records good for open-water period and fair for iceaffected period.

QUABOAG RIVER AT WEST BRIMFIEID, MASS.

LOCATION. At two-span highway bridge near railroad station of Boston & 

Albany Railroad, West Brimfield, Hampden County, one-third mile above 

mouth of Blodgett Mill Brook.

DRAINAGE AREA. 150 square miles.

RECORDS AVAILABLE. August 23, 1909, to September 30, 1926.

'GAGE. Water-stage recorder on left bank, upstream side of bridge; inspected 

by Mrs. G. G. Alien.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

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

slight shifts in control have occurred at various times.

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

recorder, 4.40 feet at 8 a. m. April 9 (discharge, 890 second-feet); minimum 

stage, 1.59 feet at 5 p. m. July 12 (discharge, 4 second-feet).

1909-1926: Maximum discharge recorded, 1,980 second-feet March 17, 

1920; minimum discharge, 2.5 second-feet September 17 and 18, 1910 (water 

held back by dams).

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

most winters.

REGULATION. Flow affected by operation of power plants at several places 

above gage. At low stages this causes a large variation in discharge on days 

when mills are in operation and a low discharge on Sundays and holidays.

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

Rating curve well defined between 15 and 600 second-feet. Operation of 

water-stage recorder satisfactory except for periods mentioned in footnote 

to table of daily discharge. Daily discharge ascertained by discharge 

integrator. Records good for open-water period and fair for period of ice 

effect.

WESTFIELD RIVER NEAR WESTFIELD, MASS.

LOCATION. At Trap Rock Crossing, 1 mile below mouth of Big Brook, 2 miles 

below mouth of Westfield Little River, and 3 miles east of Westfield, 

Hampden County.

DRAINAGE AREA. 496 square miles.

RECORDS AVAILABLE. June 27, 1914, to September 30, 1926.

GAGE, Water-stage recorder on right bank; inspected by Andrew Kelly.

DISCHARGE MEASUREMENTS. Made from cable or by wading.

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

aquatic vegetation in channel during summer. Riffle of boulders 200 feet 

below gage forms control at low and medium stages. At high stages control is probably formed by crest of storage dam at Mittineague, 3 miles 

below station.

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

recorder, 11.75 feet at 9 a. m. April25 (discharge, about 8,880 second-feet); 

minimum stage, 3.13 feet at 8.45 a. m. July 20 (discharge, 77 second-feet). 

1914-1926: Maximum stage recorded, 22.13 feet April 7, 1924 (discharge 

by logarithmic extension of rating curve, 32,500 second-feet); minimum 

stage, 2.78 feet October 2, 1921 (discharge by extension of rating curve, 9 

second-feet).

ICE. Stage-discharge relation seldom, if ever, affected by ice. River freezes 

over above and below gage, but control remains open throughout winter.

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

Springfield for municipal use.

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

ACCURACY. Stage-discharge relation for low stages subject to slight changes. 

Rating curves fairly well defined between 100 and 7,500 second-feet. Operation of water-stage recorder satisfactory. Daily discharge ascertained by 

applying mean daily gage height by inspection of recorder sheets to rating 

table. Records good.

CONNECTICUT KIVER BASIN 107

MIDDLE BRANCH OF WESTFIELD RIVER AT GOSS HEIGHTS, MASS.

LOCATION. At highway bridge in Goss Heights, half a mile above confluence 

with Westfield River, and \% miles above Huntington, Hampshire County.

DRAINAGE AREA. 53 square miles.

RECORDS AVAILABLE. July 14, 1910, to September 30, 1926.

GAGE. Water-stage recorder on right bank upstream side of bridge abutment; 

inspected by Chester W. Cady.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

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

Control somewhat shifting.

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

recorder, 4.43 feet at 4 a. m. April 25 (discharge, 1,660 second-feet); minimum 

stage, 0.68 foot August 11 and September 25 (discharge, 3.4 second-feet).

1910-1926: Maximum stage recorded, 7.33 feet July 8,1915 (discharge by 

extension of rating curve, 4,500 second-feet); minimum discharge, practically zero October 26 and 27, 1914.

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

REGULATION. Flow somewhat affected at times by operation of small power 

plant 2 miles above station. \

ACCURACY. Stage-discharge relation not permanent. Rating curves well 

defined below 1,500 second-feet. Operation of water-stage recorder satisfactory except for period indicated in footnote to daily-discharge table 

Daily discharge ascertained by applying mean daily gage height, as deter 

mined by inspection of gage-height graph, to rating table with corrections for 

effect of ice during winter. Records good for open-water periods and fair 

during winter.

HOUSATONIC RIVER BASIN

HOtJSATONIC RIVER NEAR GREAT BARRINGTOW, MASS.

LOCATION. At highway bridge one-fourth mile northeast of Van Deusenville 

station of New York, New Haven & Hartford Railroad and 2 miles north of 

Great Barrington, Berkshire County.

DRAINAGE AREA. 280 square miles.

RECORDS AVAILABLE. May 17, 1913, to September 30, 1926.

GAGE. Inclined staff attached to concrete anchorages on downstream side of 

left abutment of highway bridge; vertical high-water section attached to 

bridge abutment; read by Mrs. Herbert Armstrong.

DISCHARGE MEASUREMENTS. Made from upstream side of highway bridge or by 

wading.

CHANNEL AND CONTROL. Bed composed of sand and gravel; control for high 

stages not well denned; at low stages control is riffle a few hundred feet below 

gage.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.00 feet at 

6 p. m. April 25 (discharge, by extension of rating curve, 3,370 secondfeet); minimum stage, 0.78 foot at 5 p. m. October 25 (discharge, 19 secondfeet) .

1913-1926: Maximum stage recorded, 8.0 feet March 31, 1916 (discharge, 

by extension of rating curve, 5,300 second-feet). Zero flow recorded at various times caused by storage of water at dams above.

ICE. Stage-discharge relation seldom, if ever, affected by ice, although river 

freezes over a few hundred feet downstream from gage.

REGULATION. Storage above dam of paper mill 1 mile above station causes low 

flow on Sundays and holidays.

ACCURACY. Stage-discharge relation permanent; unaffected by ice. Rating 

curve well defined below 2,000 second-feet. Gage read to quarter-tenths 

twice a day. Daily, discharge ascertained by applying mean daily gage height 

to rating table. Records good.

The following discharge measurement was made:

July 22, 1926: Gage height, 1.49 feet; discharge, 152 second-feet.

(discharge, 13,900 second-feet); minimum stage, 1.38 feet from 8 p. m. 

August 22 to 10 p. m. August 23, 1923 (discharge, 44 second-feet).

ICE. Stage-discharge relation affected by ice.

REGULATION. Large diurnal fluctuation due to logging operations during spring. 

Seasonal distribution of flow slightly affected by storage.

ACCURACY. Stage-discharge relation affected by backwater from ice or from 

logs during most of year. Standard rating curve well defined between 200 

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

during winter. Daily discharge for periods of no backwater effect ascertained by applying to rating table mean daily gage height obtained from 

printed record by averaging hourly gage heights or, for days of considerable 

fluctuation in stage, by averaging discharges for hourly intervals of the day. 

' Daily discharge for periods of backwater effect from ice or logs ascertained 

as indicated in footnote to table of daily discharge. Records good except 

those for periods of ice or log effect and those estimated, which are fair.

HUDSON RIVER BASIN 117

HUDSON RIVER AT NORTH CREEK, N. Y.

LOCATION. At two-span! steel highway bridge in North Creek, Warren County, 

immediately above mouth of North Creek.

DBAINAGE ABEA. 792 square miles (revised; measured on topographic maps).

RECORDS AVAILABLE. September 21, 1907, to September 30, 1926.

GAGE. Chain gage on ^ipstream side of left span of bridge; read by William 

Alexander. I

DISCHARGE MEASUREMENTS. Made from upstream side of highway bridge or by 

wading.

CHANNEL AND CONTROL. Heavy gravel; fairly permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 9.2 feet at 

7.30 a. m. April 25 (discharge, 17,200 second-feet); minimum discharge, 

about 430 second-feet on July 5.

1907-1926: Maximum stage recorded, 12.0 feet during the evening of 

March 27, 1913 (dispharge, about 30,000 second-feet); minimum stage, 1.92 

feet at 7.30 a. m. and 5 p. m. September 2, 1923 (discharge, 128 second-feet).

ICE. Stage-discharge relation affected by ice.

REGULATION. Numerous lakes and ponds in the basin of the upper Hudson 

have a decided effect on low-water flow, especially the reservoir at Indian 

Lake. Many of the reservoirs are used to make flood waves in the spring in 

connection with log driving.

ACCURACY. Stage-discharge relation practically permanent except as affected 

by ice. Rating curve revised for use after April 24; curve used October 1 

to April 24 well defined between 400 and 7,000 second-feet; curve used 

April 25 to September 30 well defined between 400 and 12,000 second-feet. 

Gage read to hundredths twice daily. Daily discharge ascertained by 

applying mean daily gage height to rating table except for periods noted in 

footnote to table of idaily discharge. Records good except those for periods 

of ice effect and those estimated, which are fair.

NOTE. The monthly discharge in second-feet per square mile and run-off in inches shown by the table 

do not represent the natural flow from the basin because of artificial storage mainly in Indian Lake Reservoir. The yearly discharge and run-off doubtless represent more nearly the natural flow.

HUDSON RIVER AT HADIEY, N. Y.

LOCATION. At Hadley, Saratoga County, a quarter of a mile above mouth of

Sacandaga River and just below mouth of Lake Luzerne outlet. 

DRAINAGE AREA. 1,660 square miles (from Fourth Annual Report of New

York State Water Supply Commission).

RECORDS AVAILABLE. July 15, 1921, to September 30, 1926. 

GAGE. Friez 7-day graph water-stage recorder on right bank; inspected by

J. F. Kelly.

DISCHARGE MEASUREMENTS. Made from cable 100 yards above gage. 

CHANNEL AND CONTROL. Solid ledge with some large boulders; practically

permanent.
HUDSON EIVEE BASIN 119

EXTREMES OF DISCHARGE}. Maximum stage during year from water-stage recorder, 16.4 feet at 4 P- na. April 25 (discharge, 26,100 second-feet); minimum stage, 2.12 feei[ at noon September 14 (discharge, 832 second-feet).

1921-1926: Maxinjmm stage recorded, 19.71 feet at 3.30 p. m. April 12, 

1922 (discharge, 33,lkK) second-feet); minimum stage, 1.19 feet at 9.30 a. m. 

September 3, 1923 (discharge, 362 second-feet) .N

ICE. Stage-discharge relation affected by ice.

REGULATION. Discharge regulated to some extent by storage reservoirs at 

Indian, Schroon, and Brant Lakes and the mills on Schroon River.

ACCURACY. Stage-discharge relation practically permanent during year except 

as affected by ice or logs. Rating curve revised slightly for use beginning 

May 1; curve used prior and subsequent to May 1 well defined between 

700 and 25,000 second-feet. Operation of water-stage recorder satisfactory. 

Daily discharge for periods of no backwater ascertained by applying to rating 

table mean daily gage height obtained from recorder graph by inspection 

or, for days of considerable fluctuation in stage, by averaging discharge for 

intervals of day. For periods of backwater effect from ice or logs daily 

discharge was ascertained as indicated in footnote to table of daily discharge. Records excellent except those for periods of backwater from ice 

or logs, which are fair.

NOTE. The monthly discharge in second-feet per square mile and run-off in inches shown by the table 

do not necessarily represent the natural flow from the drainage basin because of artificial storage, mainly 

in Indian Lake Reservoir and Schroon and Brant Lakes. The yearly discharge and run-off doubtless represent very nearly the natural flow.

HUDSON KIVER AT MECHANICVILLE, N. Y.

LOCATION. At Duncan Dam of West Virginia Pulp & Paper Co. in Mechanicville, Saratoga County> 3,700 feet above mouth of Anthony Kill, 1}£ miles 

below mouth of Hoosic River, and 9 miles above mouth of Mohawk River.

DBAINAGE AREA. 4,500 square miles.

RECORDS AVAILABLE. October 1, 1887, to September 30, 1926.

GAGE. Water-stage recorder at dam, installed in 1910.

EXTREMES OF DISCHARGE. Maximum daily discharge during year, 51,800 secondfeet April 26; minimum daily discharge, 995 second-feet September 5.

1887-1926: Maximum discharge recorded, 120,000 second-feet at 6 a. m. 

March 28, 1913. The plant is occasionally shut down and the flow of the 

river stored in the pond so that the discharge below station at these times 

becomes practically zero.
121

DIVERSIONS. Water is diverted from Hudson River through the Glens Falls 

feeder and the old Champlain Canal into the summit level of the Barge 

Canal. A portion flows north into Lake Champlain. No correction has 

been made for this diversion.

ACCURACY. Discharge over spillway determined from a rating curve based on 

coefficients derived by the United States Geological Survey for dams of 

ogee section. Discharge through turbines computed from records of their 

operation. Discharge at lock and through Barge Canal turbines at lock 

computed from records of the number of lockages a day. Comparative 

studies with stations above Mechanicville indicate that the record published 

in this report is low by amounts ranging from 5 to 20 per cent, the yearly 

average being about 10 per cent low.

COOPERATION. Discharge over the spillway and through turbines of the West 

Virginia Pulp & Paper Co. furnished by Mr. W. J. Barnes, engineer of the 

company." Record of lockages obtained from the office of the State superintendent of public works.

INDIAN LAKE RESERVOIR NEAR INDIAN LAKE, N. Y.

LOCATION. At masonry storage dam at outlet of Indian Lake, 2 miles south of

Indian Lake village, Hamilton County, and 7% miles above mouth of Indian

River. 

DRAINAGE AREA. 131 square miles, including 9.3 square miles of water surface

of Indian Lake at the elevation of crest of spillway (measured on topographic

maps).

RECORDS AVAILABLE. July 22, 1900, to September 30, 1926. 

GAGE. Chain gage on dam near gate house; read by Frank Brown from October

1 to January 15, by J. L. Fish from January 16 to February 6, and by George

Campney from February 7 to September 30. Mean elevation of crest of

spillway is at gage height 33.38 feet. 

EXTREMES OF STAGE. Maximum elevation of water surface recorded during year,

35.55 feet November 15 and 16; minimum elevation recorded, 7.95 feet

April 7.

1900-1926: Maximum elevation recorded, 38.8 feet March 28, 1913;

minimum elevation, 2.0 feet March 9-18, 1907, and January 3-17, 1910. 

REGULATION. At ordinary stages discharge is completely regulated by the

operation of sluice gates. Water is held in storage until needed to augment

the flow of the upper Hudson during the low-water period. Storage capacity

is about 4.7 billion cubic feet, equivalent to a flow of about 600 second-feet for

90 days. 

COOPERATION. Record of gate openings furnished by Indian River Co.

INDIAN RIVER NEAR INDIAN LAKE, N. Y. 1

LOCATION. Three-fourths mile below dam at outlet of Indian Lake, 2 miles south 

of Indian Lake village, Hamilton County, 1 mile above mouth of Big Brook, 

and 6}£ miles above mouth of Indian River.

DRAINAGE AREA. 132 square miles (measured on topographic maps).

RECORDS AVAILABLE. July 1, 1912, to June 30, 1914; June 5, 1915, to September 

30, 1926. !

GAGE. Gurley 7-day graph water-stage recorder on right bank; inspected by 

Frank Brown, J. L. Fish, and George Campney.

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

CHANNEL AND CONTROL. Control is a reef of coarse gravel; practically permanent.

EXTREMES OF DISCHARGE. Maximum stage during year as recorded by hydrographer when inspecting recorder, 4.9 feet at 10 a. m. November 15 (discharge, 1,580 second-feet); minimum discharge occurs when all gates in dam 

are closed and there is no flow over spillway.

1912-1926: Maximum stage recorded, 7.8 feet at 4 p. m. March 28, 1913 

(discharge, 3,460 second-feet); minimum discharge occurs when all gates in 

dam are closed and there is no flow over spillway.

ICE. Stage-discharge relation occasionally slightly affected by ice.

REGULATION. Discharge is regulated by operation of sluice gates at Indian Lake 

Dam.

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

Operation of water-stage recorder satisfactory; some record lacking for period 

November to January owing to inability to obtain observer. Daily discharge 

ascertained by applying to rating table mean daily gage height obtained 

from recorder graph by inspection or, for days when there were changes in 

opening of sluice gates at Indian-Lake Dam, by averaging discharge for 

intervals of the day; for periods of no record daily discharge was ascertained 

as indicated in footnote to table of daily discharge. Records good except 

those for periods during which recorder was not operating, for which they 

are fair.

NOTE. Elevation of water surface in Indian Lake Reservoir at end of year was 14.3 feet lower than at 

begirining of year, corresponding to a loss in storage of 2,280 million cubic feet. This is equivalent to a 

run-off of 72.3 second-feet, 0.55 second-foot per square mile, or 7.44 inches on drainage area.

NORTH CREEK AT NORTH CREEK, N. Y.

LOCATION. 125 feet below dam in North Creek, Warren County, and 1,000 feet 

above mouth.

DRAINAGE AREA. 21.8 square miles (measured on topographic maps).

RECORDS AVAILABLE. July 9, 1924, to September 30, 1926.

GAGE. Vertical staff on left bank; read by William R. Alexander.

DISCHARGE MEASUREMENTS. Made from highway bridge a short distance above 

dam or by wading.

CHANNEL AND CONTROL. Gravel and small boulders; shifts occasionally.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 5.5 feet at 

7.30 a. m. April 25 (discharge, corrected for backwater from Hudson River, 

715 second-feet); minimum stage, 0.94 foot at 5 p. m. September 1 (discharge, 

0.3 second-foot; probably caused by regulation.

, 1924-1926: Maximum and minimum stages for period of record, occurred 

in 1926, as given above.

ICE. Stage-discharge relation slightly affected by ice.

REGULATION. The intentional or accidental closure of a small spillway notch in 

old dam just above gage produces a marked effect on low-water discharge 

over a period of a few days. Such a condition probably prevailed September 

1-4, 1926.

ACCURACY. Stage-discharge relation for medium and low stages changed during 

flood of April 25; affected by ice during periods from December to March 

and by backwater from Hudson River during a few days in April and May. 

Rating curve used prior to April 25 well defined between 6 and 300 secondfeet; curve used subsequent to that date, well defined between 3 and 300 

second-feet. Gage read to hundredths twice daily. Daily discharge ascertained by applying mean daily gage height to rating table, except for periods 

of backwater from ice or from Hudson River for which it was ascertained 

as indicated in footnote to table of daily discharge. Records good except for 

periods of backwater from ice or from Hudson River for which they are 

fair.

SCHROOfr RIVER AT RIVERBANK, N. Y.

LOCATION. At steel highway bridge at Riverbank, Warren County ^ 9 miles 

below Schroon Lake Reservoir and 12 miles above mouth of river.

DRAINAGE AREA. 534 square miles.

RECORDS AVAILABLE. September 2, 1907, to September 30, 1926.

GAGE. Au continuous water-stage recorder on right bank 30 feet above highway bridge; installed October 3, 1925; inspected by J. H. Roberts and W. C. 

Roberts. Prior to October 3, 1925, chain gage on upstream side of highway bridge.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Boulders and gravel; shifts occasionally. Logs 

occasionally become lodged on control causing backwater.

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

recorder, 9.6 feet at 5 p. m. April 26 (discharge, 7,720 second-feet); minimum 

stage, 1.50 feet several times in September (discharge, 191 second-feet),

1907-1926: Maximum stage recorded, 10.7 feet at 5 p. m. March 28, 1913 

(discharge, about 13,500 second-feet); minimum stage, 0.85 foot at 5 p. m. 

October 17, 1909 (discharge, 28 second-feet).

ICE. Stage-discharge relation affected by ice.

REGULATION. Flow affected by storage in Schroon and Brant Lakes.

ACCURACY. Stage-discharge relation permanent during year except as affected 

by ice. Separate rating curves developed for chain and automatic gages 

on account of slope divergence at stages above low water; curve for chain 

gage used October 1-3 well defined; curve for automatic gage used October 

4 to September 30, well defined between 200 and 6,000 second-feet. Chain 

gage read to hundredths twice daily. Operation of water-stage recorder 

unsatisfactory at times. Daily discharge for days when chain gage was used 

ascertained by applying mean daily gage height to rating table; for periods 

during which recorder operated daily discharge ascertained by applying to 

rating table mean daily gage height obtained from recorder graph by inspection or, for days of considerable fluctuation in stage, by averaging discharge for intervals of the day; for periods of ice effect and periods of no 

record discharge ascertained as indicated in footnote to table of daily discharge. Records good except those for period of ice effect, which are fair.

NOTE. Discharge Dec. 25 to Mar. 24 determined from fragmentary gage-height record corrected for ice 

effect by means of two discharge measurements, by study of weather records, and by comparison with 

flow of adjacent streams. Discharge Dec. 20, 24, July 12-14, Aug. 23-27, Sept. 13-20, and 27 ascertained by 

comparison with flow of adjacent streams on account of lack of gage-height record. Chain gage readings 

used Oct. 1-3, Jan. 3. 10-16, 30, Feb. 7, 14, 20, 28, Mar. 1-8, 10, 11, and Sept. 21-26.

SACANDAGA RIVER NEAR HOPE, N. 7.

LOCATION. \% miles below junction of East and West Branches, 4}£ miles 

above Hope, Hamilton County, and 12 miles above Northville.

DRAINAGE AREA. 494 square miles (measured on topographic maps).

RECORDS AVAILABLE. September 15, 1911, to September 30, 1926.

GAGE. Staff in three sections on left bank, the lower inclined, the middle and 

upper vertical; read by Melvin Willis.

DISCHARGE MEASUREMENTS. Made from cable 100 feet below gage or by wading.

CHANNEL AND CONTROL. Rocky; practically permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 9.0 feet at 

6.30 p. m. April 25 (discharge, about 18,600 second-feet); minimum stage, 

1.55 feet at 6.30 p. m. August 21 (discharge, 108 second-feet).

1911-1926: Maximum stage recorded, 11.7 feet during flood of March 

25-30, 1913, determined by leveling from floodmarks (discharge above 

limits of rating curve); minimum stage, 1.17 feet at 7.55 a. m. September 30, 

1913 (discharge, about 16 second-feet).

ICE. Stage-discharge relation affected by ice.

ACCURACY. Stage-discharge relation permanent except as affected by ice. 

Rating curve well defined below 10,000 second-feet. Gage read to hundredths twice daily. Daily discharge ascertained by applying mean daily 

gage height to rating table or, for days of considerable fluctuation in stage, 

by drawing a gage-height graph on basis of the two daily readings and 

averaging discharge for intervals of the day, except for period of ice effect 

for which it was ascertained as indicated in footnote to table of daily discharge. Records only fair on account of unreliable gage-height record.

second-feet).

1911-1926: Maximum stage recorded, 12.36 feet from 11 a. m. to noon 

March 28, 1913 (discharge, about 35,500 second-feet); minimum stage, 2.25 

feet all day September 16, 1913 (discharge, about 61 second-feet).

ICE. Stage-discharge relation affected by ice.

ACCURACY. Stage-discharge relation permanent except as affected by ice. 

Rating curve well defined below 14,000 second-feet. Operation of waterstage recorder satisfactory. Daily discharge ascertained by applying to 

Trating table mean daily gage height obtained from recorder graph by inspection or, for days of considerable fluctuation in stage, by averaging discharge 

for intervals of the day, except for periods of ice effect, for which it was 

ascertained as indicated in footnote to table of daily discharge. Records 

excellent except those for period of ice effect, which are fair.

BATTEN Kill AT BATTENVIIIE, N. Y.

LOCATION. 1 mile southwest of Battenville, Washington County, 3 miles below

mouth of Whitaker Brook, and 11 miles above mouth. 

DRAINAGE AREA. 397 square miles (measured on topographic maps). 

RECORDS AVAILABLE. October 1, 1922, to September 30, 1926. 

GAGE. Gurley 7-day graph water-stage recorder on left bank; inspected by

employee of Blandy Paper Co. 

DISCHARGE MEASUREMENTS. Made from cable 400 feet below gage or by

wading. 

CHANNEL AND CONTROL. Solid rock ledge extends practically across channel,

overlain with some gravel on right side; practically permanent. 

EXTREMES OF DISCHARGE. Maximum discharge recorded, 4,820 second-feet from

10 p. m. to midnight April 25 (gage height, 7.5 feet). Minimum stage, 1.94 

feet from 10 a. m. to 2 p. m. September 21 (discharge, 59 second-feet). 

1922-1926: Maximum discharge recorded, about 7,350 second-feet at

11 a. m. February 12, 1925 (gage height, 9.5 feet; stage-discharge relation 

affected by ice). Minimum stage, 1.65 feet at 6 a. m. November 19, 1924 

(discharge, 40 second-feet).
HUDSON RIVER BASIN 133

ICE. Stage-discharge relation seriously affected by ice.

REGULATION. Some diurnal fluctuation, due to operation of mills at Battenville 

and above, is noticeable during low water.

ACCURACY. Stage-discharge relation changed slightly during break-up of ice in 

March; affected by ice December 24 to March 24. Rating curves fairly 

well denned above 100 second-feet. Operation of water-stage recorder unsatisfactory at times. Daily discharge ascertained by applying to rating 

table mean daily gage height obtained from recorder graph by inspection or, 

for days of considerable fluctuation in stage, by averaging discharge for 

intervals of the day, except for periods of no record or of ice effect for which 

it was ascertained as indicated in footnote to table of daily discharge. Records 

good except those estimated or those for period of ice effect, which are fair.

BOOSIC RIVER NEAR EAGIE BRIDGE, N. Y.

LOCATION. Half a mile below mouth of Walloomsac River, lj£ miles southeast of 

Eagle Bridge, Rensselaer County, and 22 miles above mouth.

DRAINAGE AREA. 512 square miles (measured on topographic maps).

RECORDS AVAILABLE. August 13, 1910, to March 31, 1922; July 25, 1923, to 

September 30, 1926.

GAGE. Au 7-day graph water-stage recorder on left bank; installed August 17, 

1925; inspected by J. E. Sherman.

DISCHARGE MEASUREMENTS. Made from cable half a mile below gage or by 

wading.

CHANNEL AND CONTROL. Gravel, occasionally shifting.

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

recorder, 9.5 feet at 4 p. m. November 16 (discharge, 7,350 second-feet);

minimum stage, 2.05 feet at 5 p. m. September 23 (discharge, 56 second-feet).

1910-1926: Maximum stage recorded, 13.5 feet at 7.30 a. m. July 9, 1915

(discharge, about 16,700 second-feet); possibly higher stages previous to

August 17, 1914, as gage was inaccessible at extremely high water; minimum

stage, 6.1 feet (old datum) at 5 p. m. September 14, 1913 (discharge, prac1 tically zero).

ICE. Stage-discharge relation affected by ice.

REGULATION. During medium and low stages there is considerable diurnal 

fluctuation in flow caused by operation of power plants at and below Hoosick 

Falls, which is about 3/£ miles above gage, and by sawmills on Walloomsac 

River.

ACCURACY. Stage-discharge relation permanent except as affected by ice. 

Rating curve well defined. Operation of water-stage recorder very satisfactory. Daily discharge ascertained by applying to rating table mean 

daily gage height obtained from recorder graph by inspection or, for days of 

considerable fluctuation in stage, by averaging discharge for intervals of the 

day, except for periods of ice effect for which it was ascertained as indicated 

in footnote to table of daily discharge. Open-water records excellent; 

winter records fair.

136 SURFACE WATER SUPPLY, 1926, PART I 

MOHAWK RIVER AT VISCHER FERRY DAM, N. Y.

LOCATION. At Vischer Ferry Dam of Barge Canal (Lock No. 7), 1 mile above 

Stony Creek and Vischer Ferry, 7 miles below Schenectady, Schenectady 

County, and 11 miles above mouth. 

DRAINAGE AREA. 3,430 square miles (measured on topographic maps).

RECORDS AVAILABLE. Discharge June 24, 1913, to September 30, 1919; watersurface elevations only, October 1, 1919, to January 31, 1926.

GAGE. Stevens continuous water-stage recorder (showing head on crest of 

spillway) in the southerly corner of the basin near upper end of Barge 

Canal lock. Staff gage in masonry of outer lock wall just above upper 

gates. Datum of staff gage 12.1 feet lower than that of recorder. Recorder 

inspected and staff gage read by J. J. Hannan, lock tender.

CHANNEL AND CONTROL. Control is crest of spillway.

EXTREMES OF STAGE. Maximum stage during period from water-stage recorder^ 

3.0 feet at 9.30 a. m. November 14; minimum stage, 0.24 foot at 5 p. m. 

January 29.

1913-1926: Maximum stage recorded, 7.6 feet just before noon March 28, 

1914, determined by leveling from floodmarks. This stage lasted but a few 

moments and was caused by the breaking of an ice jam near Schenectady. 

Minimum stage occurred during periods when the flood gates were opened 

and water drawn below crest of spillway.

EXTREMES OF DISCHARGE. 1913-1919: Maximum discharge, about 140,000 

second-feet just before noon March 28, 1914 (estimated by engineers of the 

Department of State Engineer and Surveyor. Minimum discharge, about 

290 second-feet from 4 a. m. to 5 a. m. and 4 p. m. to 6 p. m. October 31, 

1914.

REGULATION. Considerable diurnal fluctuation is caused by operation of Lock 

No. 7, State power plant, flood gates in dam, and movable dams upstream. 

Seasonal regulation affected by operation of Hinckley and Delta Reservoirs.

DIVERSIONS. Barge Canal Lock No. 7 at the south end of dam was put in 

operation May 15, 1915. Discharge records included flow over the spillway 

and through lock and water wheels of lock power plant. State-owned 

power plant at north end of dam was put in operation January 29, 1926.

ACCURACY. From October 1, 1919, to January 31, 1926, water-surface elevations only have been published for this station, but should the occasion 

arise, conditions at the station were such that a discharge record could be 

computed. However, when operation of the State-owned power plant 

began on January 29, 1926, conditions at the station were so changed that 

the determination of discharge became practically impossible and the value 

of the gage-height record thereby greatly reduced. Hence, although the 

station was continued in operation after January 31, 1926, at the request 

of the State engineer, nothing is published after that date.

MOHAWK RIVER AT COHOES, N. Y.

LOCATION. 50 feet below School Street power plant of Cohoes Power & Light 

Corporation at Cohoes, Albany County, 500 feet below Cohoes Falls, and 

\% miles below Crescent Dam.

DRAINAGE AREA. 3,500 square miles (from annual report of New York State 

engineer and surveyor).

RECORDS AVAILABLE. October 20, 1925, to September 30, 1926, at present 

location. From December 1, 1917, to July 16, 1925, records were obtained 

at Crescent Dam, \% miles upstream. Flow at Cohoes is the flow at Crescent Dam less the amount diverted for lockages and other canal purposes 

at Lock No. 6 (Crescent Dam) on Barge Canal. A table giving daily 

.amount of diversion at Lock No. 6 is published below. City of Cohoes 

diverts a small amount of water from the fore bay of the School Street 

plant for domestic supply. This diversion is negligible and may be disregarded in comparative computations. For the period July 17 to October 

19, 1925, records of discharge were determined from gage heights above 

Cohoes Power & Light Corporation Dam and from operating records at 

School Street power plant. These records are directly comparable with 

records from present station. See under "Diversions."

GAGE. Au continuous water-stage recorder at end of concrete tailrace guard 

wall near right bank; inspected by superintendent of power plant.

DISCHARGE MEASUREMENTS. Made from upstream side of highway bridge 

half a mile below gage or, for low stages, from footbridge across powerplant canal a quarter of a mile above gage.

CHANNEL AND CONTROL. Solid rock; probably permanent.

EXTREMES OF DISCHARGE. Maximum stage during period of record, from 

water-stage recorder, 16.6 feet above 6 a. m. April 10, 1926 (discharge, 

about 52,600 second-feet); minimum stage, 3.97 feet at 7.15 a. m. September 

19, 1926 (discharge, 31 second-feet; caused by regulation).

ICE. Stage-discharge relation probably not affected by ice.

REGULATION. Seasonal regulation from storage reservoirs at Delta on upper 

Mohawk River and at Hinckley on West Canada Creek. Dams at locks 

on the canalized Mohawk River operate to flatten out flood flows. Large 

diurnal regulation from operation of School Street power plant.
138 SURFACE WATER SUPPLY, 1926, PART I

DIVERSIONS. Water is diverted at Crescent Dam through Lock No. 6 for use 

in Barge Canal which leaves the river at this point. New York City Board 

of Water Supply diverts water from Schoharie Creek, a tributary of Mohawk 

River, for municipal use. City of Cohoes diverts its water supply just 

above the School Street plant and there is also a small diversion at this 

point for industrial use, most of which returns to the river above the measuring section, and is thus included in the record.

To partly offset these diversions a considerable amount of water is received 

into Delta Reservoir from Black River Basin, through the Black River 

Canal (flowing south) and Lansing Kill. A small amount of water is also 

received through feeders from the upper Chenango Basin. Small amounts 

of water may also be received, during the navigation season, from the 

Oswego Basin through the summit level of Barge Canal, although it is 

possible that the amount of water thus gained from Oswego Basin is about 

the same amount lost from the Mohawk.

ACCURACY. Stage-discharge relation permanent during period of record. Rating curve well defined between 400 and 35,000 second-feet; extended beyond 

these limits. Operation of water-stage recorder unsatisfactory at times. 

Daily discharge ascertained by applying to rating table mean daily gage 

height obtained from recorder graph by inspection or, for days of considerable fluctuation in stage, by averaging discharge for intervals of the day, 

except as indicated in footnote to table of daily discharge. Records excellent for periods during which recorder operated satisfactorily, except for 

extremely low stages; good for other periods.

NOTE. Elevation of water surface in Hinekley Reservoir at end of year was 5.5 feet higher than at bef

inning of year, corresponding to a gain in storage of 548 million cubic feet. This is equivalent to a flow of 

7.4 second-feet, 0.05 second-foot per square mile, or 0.64 inch on drainage area.

WEST CANADA CBEEK AT EAST BRIDGE, N. Y.

LOCATION. 500 feet below highway bridge in Kast Bridge, Herkimer County, 

and 4 miles above mouth at Herkimer.

DRAINAGE AREA. 575 square miles (from report of State engineer and surveyor).

RECORDS AVAILABLE. May 15, 1905, to December 31, 1910; January 1, 1912, 

to December 31, 1913; and October 1, 1920, to September 30, 1926.

GAGE. Gurley 7-day graph water-stage recorder on left bank; inspected by 

engineers of the Department of State engineer and surveyor.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Small boulders and coarse gravel; shifting occasionally.

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

recorder, 5.8 feet from noon to 6 p. m. April 26 (discharge, 9,980 secondfeet); minimum stage, 1.65 feet at 6 p. m. September 1 (discharge, 420 

second-feet).

1920-1926: Maximum stage recorded, 7.30 feet at 11 a. m. June 21, 

1922 (discharge, about 16,500 second-feet); minimum stage, 0.95 foot at 8 

a. m. October 27, 1924 (discharge, about 50 second-feet).

ICE. Stage-discharge relation affected by ice.

REGULATION. Seasonal flow regulated by storage in Hinekley Reservoir, Consolidated Water Co.'s reservoir on Black Creek at Gray, and several small lakes. 

Diurnal flow affected by operation of mills and power plant? upstream.
HUDSON RIVER BASIN 143

DIVERSIONS. Consolidated Water Co. of Utica diverts water supply for Utica 

from Hinekley Reservoir. Water is diverted below Trenton Falls power 

plant during the navigation season through Ninemile feeder and Ninemile 

Creek into Barge Canal. A continuous record of the amount of diversion 

through Ninemile feeder from West Canada Creek at Trenton Falls d«rmg 

the navigation season is published as a separate station, "Ninemile feeder 

near Holland Patent, N. Y."

ACCURACY. Stage-discharge relation changed slightly by flood of April 8; 

slightly affected by ice December 15 to March 23. Rating curve used prior 

to April 9 well defined between 200 and 5,000 second-feet; curve used subsequently well defined between 200 and 8,000 second-feet. Operation of 

water-stage recorder satisfactory. Daily discharge ascertained by applying to rating table mean daily gage height obtained from recorder graph by 

inspection or, for days of considerable fluctuation in stage, by averaging discharge for intervals of the day. Records excellent except those for periods 

of ice effect and those estimated, which are fair.

NOTE. The monthly discharge in second-feet per square mile and run-off in inches shown by the tabledo not represent the natural flow from the basin because of artificial storage, mainly in Hinckley Reservoir. 

The yearly discharge and run-off doubtless represent very nearly the natural flow, except for the diversion out of the basin, during the navigation season, through the Ninemile feeder and Nine mile Creek into 

Barge Canal.

NINEMIIE FEEDER NEAR HOIIAND PATENT, N. Y.

LOCATION. At mouth of Ninemile feeder, half a mile below highway bridge 

near farm of P. A. Wade, 4 miles east of Holland Patent, Oneida County, 

4 miles south and 1 mile west of Barneveld.

RECORDS AVAILABLE. June 5, 1919, to September 30, 1926. Operation of station was assumed by department of State engineer and surveyor July 1, 1921.

GAGE. Gurley 7-day graph water-stage recorder on right bank; inspected by 

D. G. Humphrey.

DISCHARGE MEASUREMENTS. Made from highway bridge half a mile above gage 

or by wading.

CONTROL. Suppressed weir of concrete with a lip about 1.5 feet high and a 

spillway inclined about 1:2; permanent.

REGULATION. Flow in feeder regulated by gates at intake just below power 

plant at Trenton Falls.

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

defined between 10 and 200 second-feet. Operation of water-stage recorder 

satisfactory, except as indicated in footnote to daily-discharge table. Daily 

discharge ascertained by applying to rating table mean daily gage height 

determined by inspection of gage-height graph or, for days of considerate 

fluctuation in stage, by averaging discharge for intervals of day. Records 

excellent.

The following discharge measurements were made: 

November 6, 1925: Gage height, 0.49 foot; discharge. 12.9 second-feet. 

August 6, 1926: Gage height, 1.61 feet; discharge, 88.2 second-feet. 

September 5, 1926: Gage height, 1.72 feet; discharge, 96.3 second-feet.

FOX CREEK AT WEST BERNE, N. Y.

LOCATION. 500 feet above highway bridge in West Berne, Albany County, and 

1 mile below mouth of Switz Kill.

DRAINAGE AREA. 66 square miles (measured on topographic maps).

RECORDS AVAILABLE. August 26, 1924, to September 30, 1926.

GAGE. Staff in two sections on right bank, the lower inclined, the upper vertical; 

read by I. B. Schoonmaker.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Control is solid ledge; permanent. Bed covered with 

small boulders. During summer there is considerable weed growth in 

channel.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 5.3 feet at 

6 p. m. April 9 (discharge, 1,900 second-feet); minimum stage, 1.40 feet 

several times August 31 to September 4 (discharge, 0.9 second-foot).

1924-1926: Maximum stage recorded, 6.6 feet during night of February 11, 

1925 (discharge, about 3,160 second-feet); minimum stage recorded during 

period of August 31 to September 4, 1926.

ICE. Stage-discharge relation slightly affected by ice.

ACCURACY. Stage-discharge relation permanent except as affected by ice. Rating curve well defined between 1.5 and 1,500 second-feet. Gage read to 

hundredths twice daily. Daily discharge ascertained by applying mean daily 

gage height to rating table or, for days of considerable fluctuation in stage, 

by drawing gage-height graph on basis of the two daily gage readings and 

averaging discharge for intervals of the day, except for periods of ice effect, 

for which it was ascertained as indicated in footnote to table of daily discharge. Records good except those for periods of ice effect, which are of 

uncertain accuracy.

POESTEW Kill NEAR TROY, N. Y.

LOCATION. 500 feet below steel highway bridge on Troy-Eagle Mills road, 1}£ 

miles west of Eagle Mills, 3 miles east of Troy, Rensselaer County, and 4}£ 

miles below mouth of Quaken Kill.

DRAINAGE AREA. 88 square miles (measured on topographic maps).

RECORDS AVAILABLE. July 15, 1923, to September 30, 1926.

GAGE. Au 60-day fuzee water-stage recorder on left bank installed June 4, 

1924; inspected by engineers from Albany office of the United States Geological Survey.

DISCHARGE MEASUREMENTS. Made from cable 500 feet below gage or by wading.

CHANNEL AND CONTROL. Solid rock ledge; permanent.

EXTREMES OF DISCHARGE. Maximum discharge recorded, 1,810 second-feet at 

8 a. m. November 16 (gage height, 4.8 feet). Minimum stage, 0.90 foot 

at 9 p. m. July 8 (discharge, 4.6 second-feet).

1923-1926: Maximum discharge recorded, about 3,280 second-feet 

February 12, 1925 (gage height, determined from floodmark, 6.2 feet). 

Minimum stage, 0.89 foot at 5 p. m. July 23 and 7.30 a. m. July 24, 1923 

(discharge, 4.5 second-feet).

ICE. Stage-discharge relation usually slightly affected by ice.

REGULATION. Some regulation on Quaken Kill due to storage reservoirs for 

water supply for city of Troy.

DIVERSIONS. City of Troy diverts water for its supply from Quaken Kill 1 mile 

below Quakenkill. This diversion is said to approximate 5 second-feet and 

during low water amounts to the entire flow of Quaken Kill.

ACCURACY. Stage-discharge relation permanent except as affected by ice. 

Rating curve well defined. Operation of water-stage recorder unsatisfactory. 

Daily discharge ascertained by applying to rating table mean daily gage 

height obtained from recorder graph by inspection or, for days of considerable fluctuation in stage, by averaging discharge for intervals of the day, 

except for periods of ice effect or of no record for which it was ascertained 

as indicated in footnote to table of daily discharge. Records good except 

those for periods of ice effect or those estimated which are subject to error.

The following discharge measurements were made:

January 22, 1926: Gage height, 1.89 feet; discharge, 108 second-feet (stagedischarge relation affected by ice).

February 22, 1926: Gage height, 2.84 feet; discharge, 145 second-feet (stagedischarge relation affected by ice).

April 1, 1926: Gage height, 2.44 feet; discharge, 296 second-feet.

July 16, 1926: Gage height, 1.19 feet; discharge, 14.7 second-feet.

second-feet (corrected for backwater from ice) on March 1. Minimum 

stage, 2.30 feet several times August 11 and 12 (discharge, 17 second-feet).

1920-1926: Maximum stage recorded, 20.7 feet (old datum) at 7.30 a. m. 

March 16, 1920 (discharge, 8,350 second-feet); minimum stage occurred 

August 11 and 12, 1926.

ICE. Stage-discharge relation usually affected by ice.

ACCURACY. Stage-discharge relation changed during ice break-up in March; 

affected by debris on control October 4 to December 5 and by ice December 

12-22 and January 9 to March 10. Standard rating curve used October 1 to 

February 28 well defined; curve used March 1 to September 30 well defined 

above 30 second-feet. Gage read to quarter-tenths twice daily. Daily discharge for periods of no backwater ascertained by applying mean daily gage 

height to rating table; for periods of backwater from debris or ice daily discharge ascertained as indicated in footnote to table of daily discharge. 

Records good except those for periods of backwater effect from debris or 

ice which are fair.

SHAWAWGUNK Kill AT PINE BUSH, N. Y.

LOCATION. At Hardenburg Bridge, half a mile northeast of Pine Bush, Orange 

County, 5% miles below Platte Kill, and 10 miles above mouth.

DRAINAGE AREA. 103 square miles (measured on topographic maps).

RECORDS AVAILABLE. September 24, 1924, to September 30, 1926.

GAGE. Vertical staff in two sections on left bank. The lower section is fastened 

to bridge abutment, the upper to an oak tree near-by; read by William Low.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Solid rock ledge; probably permanent.

EXTREMES OF DISCHARGE. Maximum discharge recorded, about 1,760 secondfeet at 7 a. m. November 16 (gage height, 5.4 feet). Minimum stage, 0.70 

foot several times July 27 and 28 (discharge, 7.5 second-feet).

1924-1926: Maximum discharge recorded, about 1,860 second-feet at 8.15 

a. m. March 28, 1925 (gage height, 5.6 feet); minimum stage occurred July 

27 and 28, 1926.

ICE. Stage-discharge relation affected by ice.

ACCURACY. Stage-discharge relation practically permanent except as affected 

by ice. Rating curve revised at extremely low stages for use beginning 

March 9; both curves well denned. Gage read to hundredths twice daily. 

Daily discharge ascertained by applying mean daily gage height to rating 

table or, for days of considerable fluctuation in stage, by drawing a gageheight graph on basis of the two daily gage readings and averaging discharge 

for intervals of the day, except for period of ice effect for which it was ascertained as indicated in footnote to table of daily discharge. Records good 

except those for period of ice effect which are fair.

PASSAIC RIVER BASIN 157

PASSIAC EIVER AT PATEKSON, N. J.

LOCATION. At hydroelectric power plant of The Society for Establishing Useful 

Manufactures in Paterson, Passaic County.

DRAINAGE AREA. 785 square miles.

RECORDS AVAILABLE. January, 1898, to September 30, 1926.

DETERMINATION OP DISCHARGE. Daily discharge at Paterson determined by 

engineers of The Society for Establishing Useful Manufactures. This consists of discharge over spillway computed from a theoretic formula, discharge 

through turbines determined from manufacturers' ratings, discharge through 

the Dyers' pipe line, metered, discharge through the old race measured twice 

daily by current meter, and discharge to steam power plant.

DIVERSIONS. In the monthly-discharge table, correction has been made for 

water diverted above Paterson by Passaic Consolidated Water Co. at Little 

Falls, Newark waterworks at Macopin intake dam, Jersey City waterworks 

at Boonton, Commonwealth Water Co. at Canoe Brook well field, and East 

Orange waterworks at Canoe Brook well field. Diversions by Passaic 

Consolidated Water Co., Newark, and Jersey City are measured by Venturi 

meters; diversions by Commonwealth Water Co. and East Orange measured 

by piston displacement.

REGULATION. In monthly-discharge table correction has been made for storage 

in the Newark reservoirs at Oak Ridge, Clinton, Canistear, and Echo Lake; 

in the Jersey City Reservoir at Boonton; and in Greenwood Lake. No 

correction was made for evaporation from the surface of the various reservoirs, 

which comprise about 1 per cent of the total drainage area.

COOPERATION. Base data furnished by John H. Cook, Deputy Governor, The 

Society for Establishing Useful Manufactures, by Passaic Consolidated Water 

Co. Newark waterworks, Jersey City waterworks, Commonwealth Water 

Co., and East Orange waterworks.

Daily discharge, in second-feet, of Passaic River at Paterson, N. J., for the year 

ending September 80, 1926

power-house operators.

DISCHARGE MEASUREMENTS. For spillway, made from cable 300 feet below dam 

or by wading; for tailrace, made from temporary footbridge at gage.

DETERMINATION OF DISCHARGE. Flow at this station determined by computing 

discharge over spillway and through the two turbines (measured in the 

tailrace).

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage recorder, 1.28 feet at 2 a. m. February 27 (discharge, 2,020 second-feet; flow 

through turbines not included).

1921-1926: Maximum stage recorded, 2.58 feet at 7 p. m. April 7, 1924 

(discharge, about 6,800 second-feet; flow through turbines not included).

REGULATION. Record indicates flow as released by power plant. No correction 

made for storage in pond or for evaporation from its surface.

ACCURACY. Rating curve for spillway well defined between 40 and 2,500 secondfeet. Discharge rating for tafrace well defined. Discharge over spillway 

determined by applying mean daily gage height to rating table and by use 

of discharge integrator. Discharge through tailrace ascertained by use of 

discharge integrator; and for periods of backwater from wicket-gate openings. 

Records good.

COOPERATION. Borough of Pompton Lakes has provided the shelters for the 

water-stage recorders and furnishes the power-plant records for computation 

of discharge.

by W. C. Thorne.

DISCHABGE MEASUBEMENTS. Made from bridge or by wading.

CHANNEL AND CONTBOL. Channel of coarse gravel and rock. Control is at 

riffle 75 feet below gage.

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

recorder, 4.38 feet at 4 p. m. February 26 (discharge, 741 second-feet); 

minimum stage, 1.48 feet at 8.30 a. m. July 1 (discharge, 7 second-feet; stagedischarge relation affected by manipulation of dam).

1923-1926: Maximum stage recorded, 5.44 feet at 4 p. m. April 7, 1924 

(discharge, about 1,280 second-feet); minimum stage, 1.49 feet at 5.30 p. m. 

November 22, 1923 (discharge, 5.3 second-feet).

ICE. Stage-discharge relation affected by ice.

REGULATION. Daily distribution of flow affected by small water-power plants 

at points upstream.

ACCURACY. Stage-discharge relation subject to occasional changes, due to repairs 

made on small dam 400 feet below control; also affected by ice in winter. 

Rating curves fairly well defined above 10 second-feet. Operation of waterstage recorder satisfactory except for a few short periods. Daily discharge 

ascertained by applying to rating table mean daily gage height obtained by 

inspection from recorder charts or, for days of considerable fluctuation, by 

averaging discharge for intervals of the day. Records fair.

ELIZABETH RIVER BASIN /

ELIZABETH RIVER AT ELIZABETH, W. J.

LOCATION. Just above Westfield Avenue Bridge in Elizabeth, Union County, 

and 2}i miles above mouth.

DRAINAGE AREA. 20 square miles (measured on State topographic map).

RECORDS AVAILABLE. October 5, 1921, to September 30, 1926.

GAGE. Water-stage recorder on left bank 10 feet above dam; inspected by 

Lewis Gallagher.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CONTROL. Concrete dam, crest 48.5 feet long, at gage-height elevation 5.00 

feet, with sluice gate 24 inches in diameter, elevation of invert about gage 

height 0.3 foot. When the sluice gate is open and flowing part full, a rifHe 

of small stone below dam becomes the control.

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

recorder, 8.06 feet at 11 p. m. September 6 (discharge, about 1,170 secondfeet).

1921-1926: Maximum stage recorded, 8.18 feet at midnight July 31, 1925 

(discharge, about 1,260 second-feet).

DIVERSIONS. Elizabethtown Water Co. diverts water from Elizabeth River 

above this point, at the Ursina Lake pumping station, and through wells at 

its Hummock pumping station. Corrections for these diversions have been 

applied to the monthly table.

ACCURACY. Stage-discharge relation over spillway and through sluice gate probably permanent. Rating curve well defined below 150 second-feet. Operation of waterstage recorder satisfactory. Daily discharge ascertained by 

applying mean daily gage height to rating table; on days of considerable 

fluctuation, discharge for several periods of the day are averaged. Records 

good.

(wells), and Rahway waterworks. The total flow diverted is about 17 secondfeet and is included in the monthly table.

ACCURACY. Stage-discharge relation not permanent. Standard rating curve 

fairly well defined. Gage read to hundredths twice a day. Daily discharge 

ascertained by applying variable correction to mean daily gage height and 

then applying corrected gage height to rating table. Variable correction 

determined from periodic discharge measurements. Records fair.

recorder, 8.05 feet at 7.30 p. m. February 25 (discharge, about 4,220 secondfeet); minimum stage, 1.76 feet at 9 a. m. October 1 (discharge, about 21 

second-feet).

1903-1906; 1919-1926: Maximum stage recorded, 10.5 feet October 9,, 

1903 (discharge not determined); minimum stage, 1.76 feet at 9 a. m. 

October 1, 1925 (discharge, about 21 second-feet).

ICE. Stagerdischarge relation affected by ice.

REGULATION. Distribution of flow affected by small water-power plants at 

points upstream.

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

by ice. Rating curve well defined between 40 and 700 second-feet. Daily 

discharge ascertained by use of discharge integrator or by applying torating table mean daily gage height, as determined by inspection of 

recorder charts, corrected for ice effect during winter. Records good.

DRAINAGE AREA. 490 square miles (measured on State topographic map).

RECORDS AVAILABLE. June 27, 1903, to March 31, 1907; August 10, 1908, to 

April 30, 1915; August 19, 1921, to September 30, 1926.

GAGE. Water-stage recorder on left bank 5 feet downstream from bridge; inspected by Edward McBride.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Red sandstone on left side, sand and gravel on right 

side; permanent except as affected by vegetal growth during summer. 

Banks are overflowed at very high stages.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage recorder, 12.25 feet at 3 a. m. September 7 (discharge, about 13,200 second - 

feet; stage-discharge relation affected by grass in channel); minimum stage, 

3.20 feet at 6 p. m. July 2 (discharge, about 59 second-feet; stage-discharge 

relation affected by grass in channel).

1903-1907, 1921-1926: Maximum stage recorded, 15.9 feet October 10, 

1903 (discharge, about 25,000 second-feet); minimum stage, 3.24 feet at 9 

p. m. September 19, 1923 (discharge, about 36 second-feet).

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. Johns-Manville Co. diverts about 2 second-feet from the river at 

a point about one-fourth mile above gage. This is not included in the 

records.

REGULATION. Daily distribution of flow affected by water powers at Somerville 

and other points upstream.

ACCURACY. Stage-discharge relation permanent except as affected by the growth, 

of grass on the control during summer and by ice during winter. Standard 

rating curve well defined between 300 and 10,000 second-feet. Daily dis-' 

charge ascertained by applying to rating table mean daily gage height corrected for effect of grass or ice on control. Operation of water-stage recorder 

satisfactory. Records fair.

LOCATION. At dam of Somerset Lake & Game Club, 2 miles north of Far Hills, 

Somerset County, and 2 miles above mouth of Peapack Brook.

DRAINAGE AREA. 26 square miles (measured on State-topographic map).

EECORDS AVAILABLE. February 15, 1922, to September 30, 1926.

GAGE. Water-stage recorder on left bank 75 feet above dam; inspected by John 

Bobinson and Vincent A. Thorpe.

DISCHARGE MEASUREMENTS. Made by wading 200 feet below dam.

CONTROL. Masonry dam with flat crest having low-water notch 26 feet long 

with crest at elevation of gage height 1.696 feet. Bemainder of spillway 

137 feet long with crest at elevation of gage height 2.204 feet.

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

recorder, 4.01 feet at 9 p. m. January 18 (discharge, about 1,230 second-feet); 

minimum stage, 1.87 feet on several days in August (discharge, 7.6 secondfeet).

1922-1926: Maximum stage estimated from hydrograph, 5.1 feet at 

midnight March 7, 1922 (discharge not determined); minimum stage recorded, 1.79 feet at 9.30 a. m. August 27, 1923 (discharge, 4 second-feet).

ICE. Stage-discharge relation rarely affected by ice.

DIVERSIONS. Small turbine takes water from the pond above dam for operation 

of a pump. This turbine is operating continuously and uses about 2 secondfeet. This diversion is included in the following tables of daily and monthly 

discharge.

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

below 150 second-feet. Daily discharge ascertained by applying to rating 

table mean daily gage height as determined from recorder sheets or, for 

days of considerable fluctuation, by averaging discharge for intervals of the 

day. Becords good.

MILLSTONE RIVER AT BLACKWELLS MILLS, ff. J.

LOCATION. At highway bridge in Blackwells Mills, Somerset County, a quarter 

of a mile below mouth of Middlebrush Brook, 1% miles above Millstone, 

and 5 miles above mouth of Millstone River.

DEAINAGE AEEA. 258 square miles (measured on State topographic map).

RECORDS AVAILABLE. August 4, 1921, to September 30, 1926. A station was 

maintained at Millstone 1% miles downstream from June 28, 1903, to December 31, 1904; June 7, 1912, to April 30, 1915 (unpublished record of 

gage heights only).

GAGE. Vertical staff in two sections on downstream side of left bridge abutment; read by Alex. Barna.

DISCHAEGE MEASUREMENTS. Made by wading or from highway bridge at 

Millstone.

CHANNEL AND CONTEOL. Channel of clay. Banks are overflowed at high stages. 

Control is foundation of old stone and timber dam 100 feet downstream 

from gage; gradually disintegrating.

EXTREMES OF DISCHARGE. Maximum stage during year, estimated from hydrograph, 11.0 feet at 6 a. m. September 7 (discharge, about 6,200 secondfeet); minimum stage recorded, 0.14 foot at 6 a. m. July 10 (discharge, 32 

second-feet).

1921-1926: Maximum stage estimated from hydrograph, 11.0 feet April 

7, 1924, and September 7, 1926 (discharge, about 6,200 second-feet); minimum stage recorded, 0.0 foot all day September 16, 1923 (discharge 

about 5 second-feet).

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. Delaware & Raritan Canal takes water from Delaware River and 

flows northeastward to Raritan River. It passes along right bank of Millstone River for 15 miles above gaging station and for 5 miles below. Canal 

is above river at all points and loses water to river by leakage, seepage, and 

by discharge over spillways.

REGULATIONS. Carnegie Lake and several small mills above gage slightly affect 

distribution of flow.

ACCURACY. Stage-discharge relation not permanent. Standard rating curve 

fairly well defined; variable correction for shifting control determined from 

periodic discharge measurements. Staff gage read to hundredths twice 

daily. Daily discharge ascertained by applying corrected mean daily gage 

height to base rating. Records fair.

the stream just above station; a well field of Middlesex Water Co. and a 

second field of the Elizabethtown Water Co., Consolidated, are also located 

in the drainage area above station.

REGULATION. Daily distribution of flow slightly affected by water power above 

gage.

ACCURACY. Stage-discharge relation not permanent. Standard rating curve for 

indirect determination of discharge not well defined. Gage read to hundredths twice daily. Daily discharge ascertained by applying effective 

mean daily gage height to rating table; corrections for obtaining effective 

gage heights determined by comparing periodic discharge measurement 

with base rating. Daily discharge too uncertain to publish. Monthly 

records fair.

LAWRENCE BROOK AT PATRICKS CORNER, N. J.

LOCATION. Near highway bridge at Patricks Corner, Middlesex County, 3 miles 

southwest of Milltown, seven-eighths mile above Beaver Brook Dam and 

6J4 miles above mouth of Lawrence Brook.

DRAINAGE AREA. 29 square miles (measured on State topographic map).

RECORDS AVAILABLE. June 21, 1922, to December 31, 1926, when station was 

discontinued. Replaced by station at Farrington Dam.

GAGE. Water-stage recorder on right bank 150 feet above highway bridge; 

inspected by Henry Patrick.

DISCHARGE MEASUREMENTS. Made by wading or from highway bridge.

CHANNEL AND CONTROL. Banks high and channel fairly straight. Control is a 

concrete weir; 5.02 feet of the crest of the control are at elevation of gage 

height 1.99 feet and remaining 19.95 feet are at elevation of gage height 

2.47 feet. The top of the wing walls is at elevation of gage height 4.00 

feet. This control is submerged and a channel control becomes effective 

at very high stages. Prior to June, 1925, the control was the sill of an old 

wooden dam at the site of the present weir.

EXTREMES OF. DISCHARGE. Maximum stage during period October 1, 1925, to 

December 31, 1926, from water-stage recorder, 8.40 feet at 2 a. m. September 

7, 1926 (discharge, about 1,280 second-feet); minimum stage, 2.24 feet July 

18, 1926 (discharge, 1.7 second-feet).

1922-1926: Maximum stage, from high-water mark, 8.70 feet at 3 a. m. 

April 7, 1924 (discharge uncertain; stage-discharge relation was affected by 

brush jam below gage); minimum discharge recorded, 0.4 second-foot August 

27, 1923, and several times in October, 1924; stage-discharge relation

!. affected by grass on control).

ICE. Stage-discharge relation occasionally affected by ice.

REGULATION. Distribution of flow affected by water power above station.

ACCURACY. Stage-discharge relation permanent except when affected by grass 

and brush in channel. Rating curves fairly well defined. Operation of, 

water-stage recorder satisfactory. Daily discharge ascertained by use of 

discharge integrator or by averaging discharge for intervals of the day.

NAVESINK RIVER BASIN

SWIMMING EWER NEAR BED BANK, N. J.

LOCATION. At dam of Tintern Manor Water Co., 3 miles above Red Bank, 

Monmouth County, and mouth of river.

DRAINAGE AREA. 48 square miles (measured on State topographic map).

RECORDS AVAILABLE.: July 28, 1922, to September 30, 1926.

GAGE. Water-stage recorder on right bank 100 feet above end of dam; inspected 

by employees of Tintern Manor Water Co.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading below 

dam.

CONTROL. Dam of stone and concrete, with spillway 148 feet long. In cross 

section the spillway has a flat top 7 feet wide with downstream edge 1 foot 

higher than upstream. Sometimes sand bags are placed on the spillway 

during the summer. There are two 36-inch "blow-off" sluice gates at dam 

and one 18-inch "blow-off" sluice gate at pumping station.

DETERMINATION OP DISCHARGE. Discharge over spillway and through all sluicegates determined from rating curves based on current-meter measurements. 

Diversion measured by piston-displacement method.

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

recorder, 3.42 feet at 11.30 p. m. February 25 (discharge, about 2,590 secondfeet; over spillway only).

1922-1926: Maximum stage recorded, occurred February 25, 1926, as 

given above.

DIVERSIONS. Water diverted from dam to Newman Springs pumping station 

of the Tintern Manor Water Co. is included in tables of daily and monthly 

discharge.

STORAGE. The flow is slightly affected by storage in reservoir. Monthly table 

corrected for this by use of an approximate capacity curve.
192 SURFACE WATER SUPPLY, 1926, PART I

ACCURACY. Spillway rating permanent; fairly well defined between $ and 600 

second-feet. Daily discharge over spillway ascertained by applying to 

rating table mean daily gage height as determined by inspection from 

recorder sheets. On days of considerable fluctuation, discharge for intervals 

of the day were averaged. The storage correction is so small that possible 

errors in the capacity curve will not affect the total results. Records good.

COOPERATION. Station maintained in cooperation with and diversion figures 

furnished by Tintern Manor Water Co.

The following discharge measurements of the flow over spillway were made: 

March: 16, 1926: Gage height, 1.086 feet; discharge, 45.7 second-feet. 

July 21, 1926: Gage height, 0.981 foot; discharge, 17.9 second-feet.

Daily discharge, in second-feet, of Swimming' River near Red Bank, N. J., for the 

year ending September SO, 1926

ABSECON CHEEK BASIN

ABSECON CREEK AT ABSECOKT, IT, J, _

LOCATION. At dam of Atlantic City Water Department, 1 mile west of Absecon, 

Atlantic County, and 3 miles above mouth.

DRAINAGE ABBA. 16.6 square miles (measured on State topographic map).

EECOHDS AVAILABLE. December 1, 1923, to September 30, 1926.

DETERMINATION OF DISCHARGE. Daily discharge is computed by adding the 

flow over spillway and through a 42-inch wood-stave pipe line 9,930 feet 

long through which water flows by gravity from reservoir to pumping station, and an estimated flow that is diverted to a duck farm on left bank of 

the creek just below weir. Correction for gain or loss in storage in the 

reservoir is made to monthly discharge in order to derive the natural flow.

The discharge over the spillway and through the sluice gates and leakage 

is determined from the record made by a water-stage recorder at right end 

of a weir 48.5 feet long and 2.5 feet high with a 2-inch plank crest and 

located in channel of the creek 30 feet below spillway. The weir is submerged for a few hours each day by high tide, but the periods of submergence 

are easily recognized from the appearance of the gage-height graph.

Discharge through the 42-inch pipe line is determined from the loss of 

head at a 24-inch gate in the pipe line 100 feet below the intake in the 

reservoir. The head above the gate is indicated by the elevation of the 

water surface in the reservoir which is measured by an automatic waterstage recorder in a stilling box near the intake, prior to July 10 a hook gage 

was read twice a day. The head below the 24-inch gate is determined by a 

water-stage recorder in the caretakers' shelter 100 feet below gate. This 

water-stage recorder is over a 12-inch float tank which is connected with 

the pipe line by %-inch pipe. The two gages are set at the same datum.

Corrections for gain or loss in storage are based upon elevations in reservoir. Gages read and recorders inspected by J. E. Reilly, an employee of 

Atlantic City Water Department.
194 SURFACE WATER SUPPLY, 1926, PART I

DISCHARGE MEASUREMENTS. Measurements for rating the weir are made from 

highway bridge 10 feet below weir or by wading. Discharge measurements 

for rating pipe line are made with a Pitot tube 150 feet below 24-inch gate.

REGULATION. Flow is regulated by storage in the reservoir.

ACCURACT. Records fair.

COOPERATION. Stations installed and maintained in cooperation with Atlantic 

City Water Department, Mr. L. Van Gilder, chief engineer.

ACCURACY. Stage-discharge relation affected by backwater from eel trap or 

from ice during the greater part of first half of year; otherwise permanent 

during year. Standard rating curve well defined. Daily discharge for periods 

of .no backwater ascertained by applying mean daily gage height to rating 

table or, for days of considerable fluctuation in stage, by drawing a gageheight graph on basis of the two daily gage readings and averaging discharge 

for intervals of the day. For periods of backwater daily discharge ascertained as indicated in footnote to table of daily discharge. Records good 

except those for periods of backwater from eel trap or ice, which are fair.

DELAWARE BJVEE BASIN 199

DELAWARE RIVER AT PORT IERYIS, N. Y.

LOCATION. At steel highway bridge at Port Jervis, Orange County, \}i miles 

above mouth of Neversink River and 6 miles below mouth of Mongaup 

River.

DEAINAGE AEEA. 3,070 square miles (measured on topographic maps).

RECORDS AVAILABLE. October 12, 1904, to September 30, 1926.

GAGE. Chain gage on downstream side of left span of highway bridge and staff 

in two sections; the upper section vertical and attached to downstream end 

of left abutment; the lower section inclined, 30 feet downstream; read by 

John Bisland.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTKOL. Gravel; occasionally shifting.

EXTREMES OF DISCHARGE. Maximum discharge recorded during year, 38,700 

second-feet at 8 a. m. April 10 (gage height, 9.4 feet); minimum stage, 1.5 

feet several times July 14-16 and 22 (discharge, 745 second-feet).

1904-1926: 2 Maximum discharge recorded, 92,700 second-feet at 8 a. m. 

March 28, 1914 (gage height, 16.0 feet); minimum stage, 0.60 foot at 8 

a. m. September 22 and 23, 1908 (discharge, 175 second-feet).

ICE. Stage-discharge relation seriously affected by ice.

ACCURACY. Stage-discharge relation permanent except as affected by ice. 

Rating curve well defined below 30,000 second-feet. Gage read to quartertenths twice daily. Daily discharge ascertained by applying mean daily gage 

height to rating table or, for days of considerable fluctuation in stage, by 

drawing a gage-height graph on basis of the two daily readings and averaging 

discharge for intervals of the day, except for periods of ice effect, for which 

it was ascertained as indicated in footnote to table of daily discharge. 

Records good except for estimated and ice-affected periods, for which they 

are fair.

DELAWARE RIVER AT RIEGEISVIIIE, H. J.

LOCATION. At suspension bridge between Riegelsville, Warren County, N. J., 

and Riegelsville, Bucks County, Pa., 600 feet above mouth of Musconetcong 

River and 9 miles below Lehigh River.

DRAINAGE AREA. 6,190 square miles.

RECORDS AVAILABLE. July 3, 1906, to September 30, 1926.

GAGE. Water-stage recorder on left bank (New Jersey side) 20 feet above bridge; 

inspected by J. H. Brotzman.

DISCHARGE MEASUREMENTS. Made from bridge.

CHANNEL AND CONTROL. Rock outcrop and large boulders; practically permanent.

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

recorder, 13.05 feet at 7 a. m. April 10 (discharge, 47,100 second-feet); minimum stage, 2.12 feet at 9.30 a. m. July 28 (discharge, 1,430 second-feet; 

not including flow in Pennsylvania Canal).

1906-1926: Maximum stage recorded, 25 feet March 28, 1913 (discharge, 

144,000 second-feet); minimum stage, 1.55 feet at 8 a. m. September 20, 

1908 (discharge, 870 second-feet; not including flow in canal).

The flood of October 10-11, 1903, reached a stage of 35.9 feet determined 

by levels from three good floodmarks. Maximum discharge during this 

flood has been estimated at 275,000 second-feet at Riegelsville from observations made at Lambertville.

ICE. Stage-discharge relation affected by ice during severe winters only.

DIVERSIONS. The Delaware division of the Pennsylvania Canal diverts about 

230 second-feet from Lehigh River near its mouth from about March 31 to 

December 15 each year. Diversion not included in table of daily discharge.

ACCURACY. Stage-discharge relation permanent, unaffected by ice. Rating 

curve well defined. Operation of water-stage recorder satisfactory except for 

a few short periods. Daily discharge ascertained by applying to rating table 

mean daily gage height, determined from inspection of recorder graph, or 

for days of considerable fluctuation, by averaging discharge for intervals of 

the day. Records good.

2 p. m. April 10 (discharge, 48,100 second-feet); minimum stage, 0.03 foot 

July 15 (discharge, 1,810 second-feet). Flow in canals not included in the 

maximum and minimum discharge.

1913-1926: Maximum stage recorded, 13.3 feet during night of March 

28-29, 1913 (discharge, 160,000 second-feet); minimum stage recorded, 

 0.40 foot several times in October and November, 1914 (discharge, 1,240 

second-feet). Flow in canals not included in the maximum and minimum 

discharge.

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. Delaware division of the Pennsylvania Canal diverts about 50 

second-feet by the gaging station from about March 31 to December 15 each 

year. Delaware & Raritan Canal feeder diverts about 130 second-feet from 

March 1 to December 31 each year. The Trenton power canal diverts about 

250 second-feet around the gage daily. Diversion not included in table of 

daily discharge.
DELAWARE EIVER BASIN 205

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

by ice. Rating curve well defined. Gage read to hundredths once a day. 

Daily discharge ascertained by applying to rating table daily gage height 

corrected for ice effect when necessary. Records fair.

COOPERATION^ Gage readings furnished by United States Weather Bureau.

The following discharge measurements were made:

March 11, 1926: Gage height, 3.10 feet; discharge, 17,900 second-feet.

BEAVER XIL1 AT COOKS FAILS, N. Y.

LOCATION. At covered highway bridge in Cooks Falls, Delaware County, 5% 

miles below mouth of Willowemoc Creek and 10 miles above mouth.

DRAINAGE AREA. 241 square miles (measured on topographic maps).

RECORDS AVAILABLE. July 25, 1913, to September 30, 1926.

GAGE. Vertical staff in three sections, bolted to rock on left bank under bridge; 

read by H. B. Couch.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge or by wading.

CHANNEL AND CONTROL. Coarse gravel, boulders, and solid ledge; shifts occasionally.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 8.8 feet at 

7 a. m. November 16 (discharge, about 4,730 second-feet); minimum stage, 

1.09 feet at 3 p. m. July 28 (discharge, 3 second-feet).

1913-1926: Maximum stage recorded, about 15.0 feet during night of 

September 30, 1924, determined from floodmarks (discharge, about 13,400 

second-feet); minimum stage, 0.60 foot September 14-16, 1913 (discharge, 

about 23 second-feet; revised).

ICE. Stage-discharge relation affected by ice.

ACCURACY. Stage-discharge relation permanent during year except as affected 

by ice. Rating curve well defined below 3,000 second-feet. Gage read to 

hundredths twice daily. Daily discharge ascertained by applying mean 

daily gage height to rating table or, for days of considerable fluctuation in 

stage, by drawing a gage-height graph on basis of the two daily gage readings and averaging discharge for intervals of the day, except for periods of 

ice effect for which it was ascertained as indicated in footnote to table of 

daily discharge. Open-water records good; winter records fair.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.5 feet at 

5 p. m. April 9 (discharge, 515 second-feet); minimum stage, 0.78 foot at 

5.30 p. m. July 28 (discharge, 3.2 second-feet).

1924-1926: Maximum stage recorded, about 5.6 feet at 5 p. m. September 30, 1924 (discharge probably about 1,700 second-feet); minimum 

stage, 0.68 foot several times August 11 to September 5, 1924 (discharge, 

2.7 second-feet).

ICE. Stage-discharge relation slightly affected by ice.

ACCURACY. Stage-discharge relation changed during flood of April 9; affected 

by ice during period December to March. Rating curves well defined. 

Gage read to hundredths twice daily. Daily discharge ascertained by 

applying mean daily gage height to rating table or, for days of considerable 

fluctuation in stage, by drawing a gage-height graph on basis of the two 

gage readings and averaging discharge for intervals of the day, except for 

periods of ice effect for which it was ascertained as indicated in footnote 

to table of daily discharge. Open-water records good; winter records fair.

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

defined above 20 second-feet. Staff gage read to hundredths twice a day 

until June 22, 1926; water-stage recorder operated satisfactorily aft'er that 

date. Daily discharge ascertained by applying mean daily gage height to 

rating table for period when staff gage was used; when water-stage recorder 

was in operation discharge was ascertained by means of discharge integrator. 

Records good.

The following discharge measurements were made on April 20, 1926: 

Gage height, 1.19 feet; discharge, 129 second-feet. 

Gage height, 1.12 feet; discharge, 114 second-feet.

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

recorder, 3.63 feet at 4 a. m. February 26 (discharge, 623 second-feet); 

minimum stage, 1.21 feet August 9 and 10 (discharge, 3.3 second-feet).

1922-1926: Maximum stage recorded, 3.83 feet at noon March 17, 1923 

(discharge, 760 second-feet); minimum stage, 1.21 feet September 4, 5, and 

October 18, 1923 (discharge, 3.1 second-feet).

ICE. Stage-discharge relation affected by ice.

REGULATION. Daily distribution of flow often irregular because of operation of 

small gristmills some distance upstream.

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

Rating curve well defined between 5 and 500 second-feet. Operation of 

water-stage recorder satisfactory except for two short periods. Daily discharge ascertained by applying to rating table mean daily gage height corrected for ice effect during winter or, for days of considerable fluctuation, 

by averaging discharge for intervals of the day. Records good.

MUSCONETCONG RIVER NEAR BLOOMSBURY, N. J.

LOCATION. -At highway bridge \Yz miles above Bloomsbury, Hunterdon County, 

and 9 miles above mouth.

DKAINAGE AKEA. 143 squar^ miles (measured on State topographic map).

RECORDS AVAILABLE. July 4, 1903, to March 31, 1907; July 26, 1921, to September 30, 1926.

GAGE. Water-stage recorder on right bank just below bridge; inspected by 

Howard Person.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Channel of gravel. Control is gravel riffle 150 feet 

below gage. Banks will be overflowed at high stages.

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

recorder, 5.43 feet at 1Q p. m. February 25 (discharge, about 1,800 secondfeet); minimum stage, 0.71 foot at 11 p. m. August 10 (discharge, 22 secondfeet; stage-discharge relation affected by tree on control).

1903-1907; 1921-1926: Maximum stage recorded, 8.0 feet October 10 

or 11, 1903 (discharge, not determined); minimum discharge, 21 second-feet 

November 19, 1921.

ICE. Stage-discharge relation affected by ice.

DIVERSION AND STORAGE. Lake Hopatcong at the head of Musconetcong River 

was formerly the source of supply for Morris Canal. Through this canal 

water passed westward to Delaware River at Phillipsburg and eastward 

down the Passaic Valley to Newark. Water left in Musconetcong River, 

by the canal was measured by the gaging station near Hackettstown. Navigation in the canal was abandoned by act of the State legislature March 

13, 1924, when diversion was discontinued. Gates at the outlet of the 

lake have since been used to regulate the flow of the river to some extent. 

Monthly discharge after October 1, 1925, corrected for storage in Lake 

Hopatcong; not corrected prior to that date.

63435 30 15
220 SURFACE WATER SUPPLY, 1926, PART I

REGULATION. Distribution of flow affected by several small water powers above

the station. 

ACCURACY. Stage-discharge relation practically permanent except when affected

by ice. Rating curve fairly well defined between 50 and 1,000 seeond-fe£t.

Operation of water-stage recorder satisfactory. Daily discharge ascertained

by use of discharge integrator. Records good.-

The following discharge measurements were made: 

April 1, 1926: Gage height, 1.66 feet; discharge, 228 second-feet. 

July 10, 1926: Gage height, 0.90 foot; discharge, 33.7 second-feet (stagedischarge relation affected by tree fallen across control).

July 10, 1926: Gage height, 0.87 foot; discharge, 41.5 second-feet.

Daily discharge, in second-feet, of Musconetcong River near Bloomsbury, N. J., for 

the year ending September 30, 1926

NORTH BRANCH OF RANCOCAS CREEK AT PEMBERTON, N. J.

223

LOCATION. Near highway bridge at Pemberton, Burlington County, 11 miles 

above confluence with South Branch.

DRAINAGE AREA. 111 square miles (measured on State topographic map).

RECORDS AVAILABLE. September 15, 1921, to September 30, 1926.

GAGE. Water-stage recorde:" on left bank 800 feet below highway bridge; inspected by William Jones.

DISCHARGE MEASUREMENTS. Made from highway bridge, from boat near gage, 

or by wading.

CHANNEL AND CONTROL. Giannel of sand; shitting. Banks are overflowed at 

high stages. This station has a channel control.

IOE. Stage-discharge relation probably unaffected by ice.

REGULATION. Distribution af flow greatly affected by operation of gristmill at 

Pemperton and regulation of its pond.

ACCURACY. Stage-discharge 

poorly defined. Operat 

tember 23-30. Daily d

to mean daily gage height and then applying corrected gage height to base 

rating. Variable correction determined from periodic discharge measurements. Records fair.

Discharge measurements of 

during

relation not permanent. Standard rating curve 

on of water-stage recorder satisfactory except Sepscharge ascertained by applying variable correction

SUSQUEHANNA RIVER BASIN 

SUSQUEHANNA RIVER AT COIIIERSVIIIE, N. Y.

LOCATION. A quarter of a mile below dam and power plant of New York State 

Gas & Electric Corporation, half a mile north of Colliersville, Otsego County, 

and 1 mile above mouth of Schenevus Creek.

DRAINAGE AREA. 353 square miles (measured on topographic maps).

RECORDS AVAILABLE. July 22, 1924, to September 30, 1926.

GAGE. Gurley 7-day graph water-stage recorder on right bank; inspected by 

operators from power plant.

DISCHARGE MEASUREMENTS. Made from cable 75 feet below gage- or by wading.

CHANNEL AND CONTROL. Bed composed of coarse gravel. Control is of the 

multiple type approaching conditions of channel control. Control points 

may be expected to shift under extreme conditions of stage.
SUSQUEHANNA RIVER BASIN 225

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

recorder, 6.1 feet at 8 a. m. April 10 (discharge, 3,860 second-feet). Minimum discharge, about 8 second-feet August 19-21.

1924-1926: Maximum and minimum discharges for period were recorded 

in 1926, as given above.

ICE. Stage-discharge relation not affected by ice.

REGULATION. During greater part of year flow of the stream during the day 

is completely regulated by power-plant operation. On account of limited 

storage this regulation can extend only over very short periods.

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

between 25 and 4,000 second-feet. Operation of water-<stage recorder 

satisfactory except for a few short periods. Daily discharge, except for a 

few days during which diurnal fluctuations were small, ascertained by averaging discharge for intervals of the day or, for days of no record, by computation based on records of plant operation and flow over spillway, as 

noted in footnote to table of daily discharge. Records good except those 

based on records of plant operation which are subject to uncertainties.

SUSQUEHANNA RIVER AT CONKLIN, N. Y.

LOCATION. At steel highway bridge just below Conklin, Broome County, 5 

miles below Big Snake Creek, and 9 miles above mouth of Chenango River 

at Binghamton.

DRAINAGE AREA. 2,350 square miles.

RECORDS AVAILABLE. November 13, 1912, to September 30, 1926.

GAGE. Gurley printing water-stage recorder on left bank just below highway 

bridge; inspected by Mrs. Helena M. Smith.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Coarse gravel and boulders; shifts occasionally.

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

14.0 feet from 11 p. m. April 9 to 1 p. m. April 10 (discharge, 30,600 secondfeet); minimum stage recorded, 2.37 feet from 7 a. m. to 6 p. m. July 27 

(discharge, 434 second-feet).

1912-1926: Maximum stage recorded, 18.3 feet on morning of March 

28, 1913 (discharge, 52,000 second-feet); minimum stage, 1.32 feet September 16, 1913 (discharge, 106 second-feet).

ICE. Stage-discharge relation affected by ice.

ACCURACY. Stage-discharge relation changed slightly during flood of April 10; 

affected by ice December 17-21^ December 29 to January 5, and January 

11 to March 24. Rating curves well defined. Operation of water-stage 

recorder satisfactory except for a few short periods. Daily discharge 

ascertained by applying to rating table mean daily gage height obtained from 

printed record by averaging hourly gage heights or, for days of considerable 

fluctuation in stage, by averaging discharge for hourly intervals of the day, 

except for periods of ice effect for which it was ascertained as indicated in 

footnote to table of daily discharge. Open-water records excellent; winter 

records and estimated records, fair.

UNADILLA RIVER NEAR NEW BERLIN, N. Y.

LOCATION. At steel highway bridge a quarter of a mile below mouth of Shawler

Brook, \}i miles north of New Berlin, Chenango County, and 2 miles above

mouth of Wharton Creek.

DRAINAGE AREA. 192 square miles (measured on topographic maps). 

RECORDS AVAILABLE. July 1, 1924, to September 30, 1926. 

GAGE. Staff gage in two sections on right bank; the lower inclined, the upper

vertical; read by J. T. Gaffney.

DISCHARGE MEASUREMENTS. Made from cable or by wading. 

CHANNEL AND CONTROL. Control composed of gravel; probably subject to shift.

During the summer backwater may be expected from weed growth in the

channel. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 7.0 feet at

6 p. m. April 9 (discharge, 3,000 second-feet); minimum stage, 1.34 feet

at 7 a. m. July 25 (discharge, 22 second-feet; corrected for backwater from

aquatic growth).
230 SURFACE WATER SUPPLY, 1926, PART I

1924-1926: Maximum stage recorded, 7.6 feet February 12, 1925 (discharge, 3,750 second-feet); minimum discharge, about 18 second-feet 

' September 1, 1924; corrected for backwater from aquatic growth.

ICE. Stage-discharge relation affected by ice.

ACCURACY. Stage-discharge relation affected by backwater from ice or from 

aquatic growth throughout most of the year. Standard rating curve well 

defined between 50 and 3,000 second-feet. ' Gage read to hundredths 

twice daily. Daily discharge October 27 to December 15 and March 21 to 

May 31, when there was no backwater effect, ascertained by applying 

mean daily gage height <to rating table or, for days of considerable fluctuation in stage, by drawing a gage-height graph on basis of the two daily gage 

readings and averaging discharge for intervals of the day. For the remainder of the year, during which there was backwater from ice or from aquatic 

growth, daily discharge ascertained as indicated in footnote to table of 

daily discharge. Records fair.

Ingraham.

DISCHARGE MEASUREMENTS. Made from cable 300 feet above gage or by 

wading.

CHANNEL AND CONTROL. Sand, gravel, and small cobblestones; practically 

permanent.

EXTREMES OF DISCHARGE. Maximum discharge recorded, 20,100 second-feet 

from 11 p. m. April 9 to 4 a. m. April 10 (gage height, 10.2 feet); minimum 

stage, 2.60 feet from 7 p. m. July 28 to 10 a. m. July 29 (discharge, 295 

second-feet).

1912-1926: Maximum stage recorded, 13.7 feet on afternoon of March 

27, 1913 (discharge, 35,500 second-feet); minimum stage, 2.20 feet several 

times in August and September, 1913 (discharge, 92 second-feet).

ICE. Stage-discharge relation seriously affected by ice.

ACCURACY. Stage-discharge relation changed slightly during ice break-up in 

March; affected by ice December 16-21 and December 28 to March 24. 

Rating curves well defined below 15,000 second-feet. Operation of waterstage recorder satisfactory. Daily discharge ascertained by applying to 

rating table mean daily gage height obtained from printed record by averaging hourly gage heights or, for days of considerable fluctuation in stage, 

by averaging discharge for hourly intervals of the day, except for period 

of ice effect for which it was ascertained as indicated in footnote to table 

of daily discharge. Open-water records excellent; winter records fair.

TIOGA RIVER NEAR ERWINS, N Y

LOCATION. At steel highway bridge a quarter of a mile below mouth of Canisteo 

River near Erwins, Steuben County, and 3 miles above confluence of Tioga 

and Cohocton Rivers, which form Chemung River at Painted Post.

DRAINAGE AREA. 1,320 square miles (furnished by Robert 0. Hayt).

RECORDS AVAILABLE. July 12, 1918, to September 30, 1926.

GAGE. Chain on downstream side of bridge near left abutment; read by Miss 

Jane Sexton.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge or by 

wading.

CHANNEL AND CONTROL. Bed and control composed of well-compacted gravel; 

fairly permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 9.6 feet at 

7 a. m. April 9 (discharge, 15,800 second-feet); minimum stage, 0.82 foot at 

7.40 a. m. August 6 and noon August 8 (discharge, 64 second-feet).

1918-1926: Maximum stage recorded, 16.4 feet at 4 p. m. May 22, 1919 

(discharge, about 46,700 second-feet); minimum stage, 0.62 foot at 5.40 

p. m. August 22, 1923 (discharge, 31 second-feet).

ICE. Stage-discharge relation affected by ice.

REGULATION. Storage not sufficient to affect the seasonal flow.

ACCURACY. Stage-discharge relation permanent except as affected by ice. 

Rating curve well defined between 75 and 15,000 second-feet. Gage read 

to quarter-tenths twice daily. Daily discharge ascertained by applying 

mean daily gage height to rating table or, for days of considerable fluctuation in stage, by drawing gage-height graph on basis of the two gage readings 

and averaging discharge for intervals of the day, except for periods of ice 

effect for which it was ascertained as indicated in footnote to table of daily 

discharge. Open-water records good, except those for low-water season 

when daily discharge determined from mean of two gage readings daily 

may be considerably in error owing to fluctuations in stage caused by power 

operations upstream. Records for periods of ice effect and those estimated, 

fair.

CAWACADEA CREEK AT HORWEIL, W. Y.

LOCATION. At Senaca Street Bridge in Hornell, Steuben County, a quarter of a 

mile above confluence with Canisteo River.

DRAINAGE AREA. 58.5 square miles (measured on topographic maps).

RECORDS AVAILABLE. October 18, 1924, to September 30, 1926.

GAGE. Vertical staff on downstream side of left bridge abutment; read by an 

employee of the city engineer of Hornell prior to April 7, 1926; thereafter by 

engineers of New York State Department of Public Works.

DISCHARGE MEASUREMENTS. Made from upstream side of bridge or by wading.

CHANNEL AND CONTROL. Control for low stages is a gravel bar 150 feet below 

gage; for medium and high stages channel-control conditions exist. Bed 

composed of gravel and is subject to shift.

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

8.30 a. m. September 24 (discharge, from extension of rating curve, 1,100 

second-feet); minimum stage, 1.06 feet at 6.30 p. m. July 25 and 5.30 p. m. 

July 27 (discharge, 3.5 second-feet).

1924-1926: Maximum stage recorded, that of September 24, 1926; minimum stage recorded, 0.98 foot at 8 a. m. November 4, 1924 (discharge, about 

2.7 second-feet).

The flood of February 11, 1925, greatly exceeded that of September 24, 

1926, but no determination of discharge can be made on account of lack of 

gage-height record.

ICE. Stage-discharge relation affected by ice.

ACCURACY. Stage-discharge relation permanent during period of record except 

as affected by ice. Rating curve well defined between 5 and 300 second-feet; 

extended beyond these limits. Gage read to hundredths twice daily during 

most of January and subsequent to April 7; no readings made during remainder of year. Daily discharge ascertained by applying mean daily gage 

height to rating table or, for days of considerable fluctuation in stage, by 

drawing a gage-height graph on basis of the two gage readings and averaging 

discharge for intervals of the day, except for periods of ice effect or of no 

record for which it was ascertained as indicated in footnote to table of daily 

discharge. Records good except those for periods of ice effect or of no 

record which are fair.

COHOCTOH RIVER NEAR CAMPBEII, N. T.

LOCATION. At steel highway bridge 2 miles upstream from Campbell, Steuben 

County, and 11 miles above Painted Post, where Cohocton and Tioga Rivers 

unite to form Chemung River.

DRAINAGE AREA. 480 square miles (furnished by Robert O. Hayt).

RECORDS AVAILABLE. July 11, 1918, to September 30, 1926.

GAGE. Chain gage on downstream side of bridge near left abutment; read by 

Miss Dora Wood.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge or by 

wading.

CHANNEL AND CONTROL. Bed and control composed of well-compacted gravel; 

fairly permanent. Heavy aquatic growth in channel during summer.

EXTREMES OF DISCHARGE. Maximum discharge, 5,350 second-feet at 5.10 p. m. 

March 25 (gage height, 5^7 feet); minimum discharge recorded, about 32 

second-feet August 2, 3, 11, and 12 (discharge corrected for backwater from 

weeds).

1918-1926: Maximum discharge, 11,300 second-feet at noon March 12, 

1920; minimum stage recorded, 0.68 foot at 5 p. m. October 7, 1921 (discharge corrected for backwater from weeds, about 13 second-feet).

ICE. Stage-discharge relation affected by ice.

REGULATION. Seasonal distribution of flow is probably not affected by small 

reservoirs above.

ACCURACY. Stage-discharge relation affected by backwater from ice or from 

aquatic growth throughout most of year. Standard rating curve fairly well 

defined between 200 and 4,000 second-feet. Gage read to quarter-tenths 

twice daily. Daily discharge for periods during which there was no backwater ascertained by applying mean daily gage height to rating table or, 

for days of considerable fluctuation in stage, by drawing a gage-height 

graph on basis of the two gage readings and averaging discharge* for intervals 

of the day. For periods of backwater from ice or from aquatic growth daily 

- discharge ascertained as indicated in footnote to table of daily discharge. 

Records good for periods during which stage-discharge relation was not 

affected by backwater from ice or aquatic growth; fair for periods of backwater.

LOCATION. At Columbia Turnpike Bridge, \% miles northeast of Burtonsville,

Montgomery County, and 4 miles northwest of Laurel. 

DRAINAGE AREA. 127 square miles. 

RECORDS AVAILABLE. July 21, 1911, to June 15, 1912 (records furnished by

United States Engineer Office); July 21, 1913, to September 30, 1926. 

GAGE. Au water-stage recorder on left bank 80 feet below highway bridge;

installed August 8, 1922; inspected by Arthur Beall. 

DISCHARGE MEASUREMENTS. Made from bridge or by wading. 

CHANNEL AND CONTROL. Banks lined with trees and brush; overflowed at stage

of about 10 feet. Control poorly defined; shifted during year.
242 SURFACE WATER SUPPLY, 1926, PART I

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

recorder, 15.27 feet at lip. m. September 5 (discharge, about 4,500 secondfeet); minimum stage, 1.93 feet from 7 a. m. to 5 p. m. August 14 (discharge, 

25 second-feet).

1911-1926: Maximum stage recorded, that of September 5, 1926; minimum stage, 0.18 foot August 25, 1911 (discharge, 6 second-feet).

ICE. Stage-discharge relation affected by ice.

REGULATION. Fluctuation at low stages has been noticed and is probably 

caused by operation of a power plant above gage.

ACCURACY. Stage-discharge relation not permanent; affected by ice. Rating 

curves fairly well defined. Operation of water-stage recorder satisfactory 

except as indicated in footnote to table of daily discharge. Daily discharge 

ascertained by applyulg mean daily gage height determined from recorder 

graph to rating table, or for days of considerable fluctuation in stage by 

averaging discharge for fractional parts of a day, or as explained in footnote 

to daily discharge table. Records good except during winter, when stage is 

affected by ice, and for estimated periods for which they are fair.

water. Right bank rather low, covered with brush, and subject to overflow at stage of about 14 feet; left bank high, not subject to overflow. Bed 

of boulders and bedrock. Control is composed of large, flat, angular rocks 

broken from rock ledge a short distance above; probably permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 8.85 feet at 

7.30 a. m. August 19 (discharge, 5,250 second-feet); minimum stage, 2.29 

feet at 3 p. m. August 12 (discharge, 33 second-feet).

1924-1926: Maximum stage recorded, that of August 19, 1926; minimum stage, 2.26 feet November 9-10, 1924 (discharge, 30 second-feet).

Flood of March 29, 1924, reached a stage of 20.3 feet (discharge not determined), determined from debris and floodmarks by local residents.

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

REGULATION. Low-water flow affected by a storage reservoir on Stony River 

27 miles upstream, having a capacity of 204 billion cubic feet and drainage 

area of 114 square miles.

DIVERSIONS. None.

ACCURACY. Stage-discharge relation permanent; affected by ice December 

25-31 and January 1, 10-15. Rating curve well defined. Gage read to hundredths twice daily except as noted in footnote to daily-discharge table. 

Daily discharge ascertained by applying mean daily gage height to rating 

table. Records good.

POTOMAC RIVER BASIN 245

POTOMAC RIVER AT POINT OF ROCKS, MD.

LOCATION. At steel highway bridge at Point of Rocks> Frederick County, onethird of a mile below Catoctin Creek and 6 miles above Monocacy River.

DRAINAGE AREA. 9,650 square miles.

RECORDS AVAILABLE. February 17, 1895, to September 30, 1926.

GAGE. Chain gage attached to downstream side of left span of bridge; read by 

W. W. Compher. Datum constant since September 2, 1902; prior to this 

date datum was 0.45 foot higher than at present. Sea-level elevation of jzero 

of gage, 200.54 feet.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Practically permanent. Control is a rock ledge a few 

hundred feet below station, the ledge extending completely across the itiver 

except for one small channel.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 10.80 fee^t at 

4.30 p. m. February 26 (discharge, 55,200 second-feet); minimum stage, 0.64 

foot at 2 p. m. October 1 (discharge, 922 second-feet).

1895-1926: Maximum stage recorded, 32.2 feet May 13,1924 (discharge, 

258,000 second-feet); minimum stage, 0.38 foot September 10, 1914 ^discharge, 540 second-feet).

The crest of the flood of June 2, 1889, as determined by the United Spates 

Engineer Corps from high-water marks, reached a stage of 40.2 feet (discharge, about 320,000 second-feet).

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. The Chesapeake & Ohio Canal parallels the Potomac on the 

Maryland side. The average discharge of the canal is 75 to 100 second^feet. 

The discharge of the canal is not included in the records for this station.

REGULATION. Fluctuation at extremely low stages has been noted and is probably caused by the operation of power plants or storage reservoirs oii the 

upper Potomac and its tributaries.

ACCURACY. Stage-discharge relation practically permanent; affected bjf ice 

December 27 to January 5 and January 10-19. Gage read to hundredths 

once daily; during high water read oftener. Rating curve well defined. 

Daily discharge ascertained by applying gage height to rating table except

for period affected by ice. Records good. %

The following discharge measurement was made:

October 1, 1925: Gage height, 0.68 foot; discharge, 982 second-feet.

AND CONTROL. Bed composed of boulders, somewhat rough. One 

channel for all stages. Banks wooded; water overflows right bank at stage 

of about 15 feet and left bank at about 12 feet. Current sluggish at extremely low water. Control is a rocky section a few hundred feet below 

gage; practically permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 7.93 feet at 

7 a. m. September 24 (discharge, 20,100 second-feet); minimum stage, 0.43 

foot at 4 p. m. October 4 (discharge, 92 second-feet).

1907-1926: Maximum stage recorded, 16.5 feet at 1 a. m. May 13, 1924 

(discharge estimated, about 66,000 second-feet); minimum stage, 0.28 foot 

from 2 to 5 a. m. September 15, 1925 (discharge, 64 second-feet).

ICE. Ice forms near gage but seldom in sufficient quantity at control to affect 

stage-discharge relation.

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

defined between 90 and 27,000 second-feet; extended beyond these limits. 

Operation of water-stage recorder satisfactory, except as indicated in footnote to table of daily discharge. Daily discharge ascertained by applying 

to rating table mean daily gage height obtained by inspection of recorder 

graph or by averaging discharge for intervals of a day. Records good.

The following discharge measurements were made:

October 28, 1925: Gage height, 1.17 feet; discharge, 389 second-feet.

June 5, 1926: Gage height, 1.26 feet; discharge, 475 second-feet.

Banks high, wooded, and will be overflowed at extremely high stages. Control is ledge rock 100 feet below; probably permanent, except for being 

affected occasionally by driftwood.

EXTREMES OF DISCHARGE. Maximum stage recorded during the period ending September 30, 1926, 9.35 feet at 2 p, m. August 21 (discharge, 2,010 

second-feet); minimum stage, 3.62 feet at 2 p. m. August 14 (discharge, 

49 second-feet).

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

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

between 60 and 800 second-feet; fairly well defined above. Gage read to 

hundredths once daily except Sundays. Daily discharge ascertained by 

applying daily gage height to rating table. Records good.

The following discharge measurements were made: 

March 23, 1926: Gage height, 4.72 feet; discharge, 233 second-feet. 

May 14, 1926: Gage height, 4.18 feet; discharge, 135 second-feet.
