UNITED STATES GEOLOGICAL SURVEY,

HYDROGRAPHIC BRANCH, 

Washington, D. C., May 5, 1904.

SIR: I have the honor to transmit herewith a manuscript by John 

C. Hoyt and Robert H. Anderson, relating to the hydrography of the 

Susquehanna River drainage basin, and recommend its publication 

in the series of Water-Supply and Irrigation Papers.

In this paper has been brought together, in such form as to be of 

use to both the general and the engineering public, all the available 

hydrographic information in regard to this important area.

It is intended that this paper shall be published in sequence with 

another (No. 108) entitled "Quality of Water in the Susquehanna 

River Drainage Basin, by Marshall Ora Leighton, with an Introductory Chapter on Physiographic Features, by George Buell Hollister." 

The combination of the two papers will make available a large 

amount of valuable information with reference to the resources of 

this important river system. 

Very respectfully,

F. H. NEWELL, Chief Engineer. 

Hon. CHARLES D. WALCOTT,

Director United States Geological Survey.

HYDROGRAPHY OF THE SUSQUEHAMA RIVER BASIN,

By JOHN C. HOYT and ROBERT H. ANDERSON.

INTRODUCTION.

A detailed study of the hydrographic features of the Susquehanna 

River drainage basin has revealed the existence of a large amount of 

interesting data. These, however, are widely distributed in various 

publications and manuscripts which are in most cases inaccessible. 

This paper has been prepared to meet the constant demand for this 

information from both the general and the engineering public. The 

general deductions are intended to give the general reader a comprehensive review of the principal conditions which exist in this area, 

while the base data have been given for the use of the engineer, so 

that he may make his own deductions and have sufficient data for 

estimates in hydraulic investigations.

ACKNOWLEDGMENTS.

The records and reports of the United States Geological Survey 

have been the chief sources from which the data on flow have been 

obtained. These records have been carefully revised and in many 

cases recomputed. New rating tables based on all the discharge 

measurements to date have been prepared and the tables of estimated 

discharge have been revised to agree with these rating tables. These 

recomputations will account for the differences between the figures 

herein presented and many of those in the previous reports, as the 

latter were prepared from year to year with such information as was 

available. Spe'cial acknowledgment is due to E. G. Paul, resident 

hydrographer for Pennsylvania, who established the gaging stations 

and under whose direction the discharge measurements in this State 

have been made. The stations in New York were established and 

have been maintained under the direction of R. E. Horton, resident 

hydrographer for that State.

The base data from which the precipitation tables have been prepared were taken from the published reports of the United States 

Weather Bureau.
10 HYDEOGEAPHY OF SUSQIJEHANNA BASIN. [NO. iO&.

The tables showing the utilized horsepower in 1900 are from manuscript schedules furnished by the manufactures division of the 

Twelfth Census.

In the preparation of descriptive portions of the paper Vol. XVI 

of the reports of the Tenth Census (Water Powers, Part I), Rogers's 

Geology of Pennsylvania, and the Army Engineers' reports have been 

largely drawn upon.

The annual reports and original records of the Chief of Engineers, 

United States Army, have furnished valuable information in regard 

to declivity, and the profiles herewith given are largely based upon 

them.

The data for McCalls Ferry have been furnished through the kindness of Dr. Cary T. Hutchinson, of New York City, who is interested 

in the power development at that point and had charge of extensive 

surveys and studies there in 1902 and 1903. Special mention is due 

Boyd Ehle and R. H. Anderson, who established and carried on the 

measurements at the McCalls Ferry gaging station.

Acknowledgment is also due to Frank H. Brundage, H. J. Saunders, 

L. R. Stockman, and other members of the hydro-computing section 

of the United States Geological Survey for assistance given in the 

computations and in other work connected with the preparation of 

the many tables.

DESCRIPTION OF DRAINAGE AREA.

GENERAL FEATURES.

The Susquehanna River basin is the largest and most important 

drainage area commercially in the North Atlantic States, although it 

is not the most important as regards water power, The headwaters 

of this river system are on the elevated plateau which separates the 

waters which flow south and east into the Atlantic streams from those 

flowing north and west into the Mississippi, St. Lawrence, and Great 

Lakes.

Geologically, this watershed lies in four physiographic divisions: 

the Allegheny Plateau, the Allegheny Mountains, the Great Allegheny 

Valley, and the Piedmont Plateau. Its distribution among these 

provinces is approximately as follows: Allegheny Plateau, 56 per 

cent; Allegheny Mountains, 31 per cent; Great Allegheny Valley, 6 

per cent; Piedmont Plateau, 7 per cent.

As the physical features of the foregoing divisions and the early 

history of the formation of this basin, as well as the quality of the water, 

have been fully discussed by Messrs. G. B. Hollister and M. O. Leigh ton 

in Water-Supply Paper No. 108, further discussion here is omitted.

The Susquehanna drainage basin, as shown in fig. 1, has a total area 

of 27,400 square miles. It'comprises 21,060 square miles in Pennsylvania, or about 47 per cent of the area of the State; 6,080 square 

miles in New York, or 13 per cent of the area of the State; 260 square 

miles in Maryland, or about 2 per cent of the area of the State. It

SUSQUEHANNA RIVER BELOW WEST BRANCH.

Susquehanna River is joined by the West Branch at Sun bury, 

Northumberland County. Below this point the river drains an area 

of 9,230 square miles. It flows nearly south, between Northumberland, 

Dauphin, and Lancaster counties on the east and Snyder, Juniata, 

Perry, Cumberland, and York counties on the west, passing then into 

Maryland, where it flows between Cecil County on the east and Harford County on the west, and empties into Chesapeake Bay at its 

northern extremity.

Below the mouth of the West Branch the fall becomes more irregular than above, and there are rapids where the stream flows over a 

rocky bottom. In the lower part of its course from Marietta to Havre 

de Grace the river occupies a deep valley, varying in width from 

a few hundred yards to more than 2 miles, and on either shore it 

is for the most part bounded by rocky bluffs surmounted by a tableland 100 to 500 feet above the stream. The channel is in many places 

filled with small rocky islands, some of which are cultivated. Pis. I, 

J5, and VIII show typical views of this part of the river.

The fall of the main river is rapid. Its elevation at the mouth of 

the West Branch is about. 400 feet above mean sea level at Havre de 

Grace. The distance between this point and Havre de Grace is about 

125 miles, hence the mean slope of the main river is nearly 3-£ feet 

per mile. The slope is, however, extremely variable, being over 5 

feet per mile in the lower 40 miles and about 2| feet per mile in the 

upper 40 miles. The change in slope takes place as the river passes 

from the Allegheny Mountain and the Allegheny Valley regions to the 

Piedmont Plateau region.

The tables on pages 207-210 give the elevation of the river and its 

branches at various points, and Pis. XXVIII and XXIX show their 

profiles.

This part of the river is described by Prof. H. D. Rogers as follows : a

Between Northumberland and the Kittatinny Valley the river leads us through 

many striking scenes. It is studded with many little islands, most of which are 

covered with trees or bushes to the water's edge, and it is here a wide and majestic 

river, flowing alternately for long reaches across highly cultivated belts of country and past the ends of steep and rugged mountains. Passing oat from the 

mountains it traverses a beautiful country in the Kittatinny Valley, dividing 

Dauphin from Cumberland County. Quitting the limestone valley the river 

next traverses the red-shale belt, between the villages of Highspire and Bainbridge, crossing a rather monotonous country, except at the Conewago Falls, or 

rapids, where numerous hard trap dikes impede its course and cause it to rush in 

wild tumult, by deep and dangerous sluices, for a long distance between black 

and jutting reefs. At Chickies Ridge, 1 mile above Columbia, the river leaves 

the smoother country and passes between a range of high and picturesque crags. 

With two or three intermissions, caused by the softer limestone valleys which it 

next crosses, it runs the whole way thence to the vicinity of Port Deposit, or 

nearly to the Chesapeake Bay. between steep naked and half naked hillsides, rising

f'Oeol, Pennsylvania, p. 49-
20 HYDEOGEAPHY OF SUSQUEHANNA BASIN. [NO. 109.

from 200 to 400 feet above its channel. In some parts of this long reach, as at 

Washington Borough, the river is greatly dilated and is filled with rocky islands 

and projecting reefs. In other localities its rugged banks approach, and the river 

rushes with tremendous force, especially during freshets, through these deeper 

gorges. The traveler, who finds only a rough and very toilsome path along its 

eastern shore from Turkey Hill to Port Deposit, a distance of more than 30 miles, 

will choose to descend it by its right bank along the towpath of the canal. He 

will pass an almost unbroken succession of interesting rocky scenes, affording 

much geological instruction, and he will witness many beautiful bits of river perspective, but he will find himself pent in all the way between the bold river hills.

The principal tributary below the West Branch is the Juniata, which 

has its source in Bedford, Blair, and Somerset counties, Pa., at an elevation of about 2,000 feet above sea level. The divide between its 

waters and those of the Ohio attains in places a height of nearly 2,800 

feet. The valley of the stream is narrow and the banks are generally 

high. The stream has a number of both large and small tributaries. 

Doctor Rogers describes the Juniata as follows:*

This second great tributary of the Susquehanna has two chief upper divisions, 

the Frankstown and the Raystown branches, both of which, like the main stream 

below their junction, traverse much beautiful scenery. We will trace the Frankstown Branch as that which is most accessible. After gathering its headwaters 

from the eastern slope and the foothills of the Allegheny Mountains it begins to 

assume the volume of a small river near Frankstown. Below this point it first 

passes the cove of the Lock Mountain, a curious district of conical hills, in structure like the Muncy Hills of the West Branch. Its course is now by a wild and 

rocky gorge through the Lock or Canoe Mountain into Canoe Valley. Winding 

northeastward through this valley it next goes through Tusey Mountain into 

Hartslog Valley by an interesting curving pass of the form of the letter S. The 

mountain, which consists of two ridges, is trenched along its center for the passage of the river, and the western ridge is, moreover, breached at Water street by 

a lateral notch, which gives passage to a small tributary stream and heightens 

much the picturesqueness of the place, which is further enhanced by a great stone 

slide covering the ends of the mountain. Crossing Hartslog Valley it next traverses Warrior Ridge, passing by the Pulpit Rocks. Emerging from the Warrior 

Ridge and deflecting more toward the east it crosses the Huntingdon Valley and 

passes by the northern end or knob of Terrace Mountain or Slideling Hill, receiving first the Raystown Branch, which nearly doubles the volume of its waters, 

Here, bending southward, it follows a picturesque gap through Stone Ridge, and 

turning more eastward it presently enters the deep cleft in Jacks Mountain called 

" Jacks Narrows," upon the western side of which the mountain is covered with 

a great stone slide or field of naked angular blocks of sandstone, which imparts a 

most desolate aspect to the pass, especially when the forest is not in leaf.

On emerging from Jacks Narrows the river crosses a succession of open valleys 

divided by narrow ridges until it meets the base of Blue Ridge in Sugar Valley. 

There it makes a great loop, turning in an oxbow backward till it reaches Newton 

Hamilton, where it flows with many large sinuosities longitudinally through the 

Juniata or Lewistown Valley to the deep synclinal ravine called the " Long Narrows," formed by the near approach of the Blue and Shade mountains. The 

Long Narrows of the Juniata is a narrow trough between mountain ridges, deeply 

trenched on their flanks and thickly clothed with timber on their lower slopes and

ANDBBSOI?.] DESCRIPTION OF DRAINAGE AREA. 21

at their base, and overspread nearer their summits with extensive sloping sheets 

of dark-gray angular blocks. The pass is 7 miles long and is one of the wildest and 

most impressive within the mountains. At the eastern end of the Long Narrows 

the river turns southeastward and winds between hills and valleys across the 

country to the base of the Tuscarora Mountain, passing Mifflintown, Mexico, and 

other villages. Below New Mexico it sweeps the base of the Tuscarora Mountain 

for several miles, until it turns abruptly across its eastern end a mile northwest of 

Millerstown. Below Millerstown the river crosses the Wildcat and Buffalo valleys, washing the end of the Buffalo Mountain. Pursuing its course, the Juniata. 

after making two or three bends, flows through a belt of hills called the " HalfFall Mountain," where, as at nearly all its passes through the larger sandstone 

ridges, it is impeded by ledges of hard strata and thrown into ripples or rapids. 

From the Half-Fall Rapids it flows between steep but low cliffs and hills for about 

4 miles farther, to its entrance into the main Susquehanna at Duncans Island, 

having followed a winding course entirely across the central zone of the Appalachian chain through a distance of nearly 200 miles.

SUSQUEHANNA RIVER ABOVE WEST BRANCH.

This portion of the stream and its tributaries drain an area of about 

11,140 square miles, of which 6,080 are in New York and 5,060 in 

Pennsylvania. It rises in Otsego Lake, in Otsego County, N. Y., 

which is about 7% miles long and li miles wide, and has an 

elevation of about 1,193 feet above sea level. It flows in a southwesterly direction through Otsego, Chenango, and Broome counties, 

N. Y., into Susquehanna County, Pa. It then flows in a westerlynorthwesterly direction through this county and again enters New 

York and takes a westerly course through Broome and Tioga counties to near the western boundary of Tioga County, where it turns 

south and enters Pennsylvania. Before leaving New York its volume 

is rapidly swelled by many large tributaries. After entering Pennsylvania the second time it flows through Bradford, Wyoming, Luzerne, 

Columbia, Montour, and Northumberland counties to its junction with 

the West Branch, above Sunbury.

This portion of the drainage basin is varied in character. In New 

York it is a rolling and sometimes rather broken country, forming the 

plateau bounding the mountain region on the north. The stream has 

a very uniform declivity in this part of its course and offers comparatively little power. Its bed is gravel or sand, with an occasional 

rocky ledge. Its banks are moderately high, shelving, and are subject to overflow only in extreme freshets.

After it enters Pennsylvania it flows through the mountain regions, 

and its course is in many places tortuous as it winds along the parallel ranges of hills. In general, however, its fall is gradual, its bed 

being composed mostly of drift materials gravel, sand, and bowlders. The banks, as in New York, are generally high and are seldom 

overflowed, although the river has an extreme rise of as much as 30 

feet.

In this portion of the drainage area is located the great Lackawanna 

and Wyoming coal basin, and J. H. Dager reported upon this, in sub-
22 HYDROGRAPHY OF SUSQUEHANNA BASIN. [NO. 109.

stance, as follows: a This basin extends from Nanticoke on the southwest, where the river emerges from the Coal Measures, to Carbondale 

on the northeast. It is about 50 miles in length and averages 3^ miles 

in width. It is surrounded by the Allegheny Mountains, which are 

composed of the Catskill formation and rocks of the Carboniferous 

system.

In this vicinity there are several workable seams of coal, ranging 

from 3 to 14 feet in thickness and at depths varying from nothing to 

800 feet. These seams are from 10 to 200 feet apart vertically, and 

are underlain by sandstone and fire clay.

From the outcrop of the Coal Measures just above Pittston to the 

New York State line the country is traversed by long, narrow, parallel 

ranges of mountains whose axes are nearly at right angles to the general direction of the river. At bends on the convex side there rise 

from the shore abrupt cliffs from 200 to 400 feet in height, opposite 

which, with one or two exceptions, are gently sloping cultivated lands.

Professor Rogers refers to this portion of the river as follows: 6

That portion of the Susquehanna River which flows near the northern boundary 

of the State passes from its sharp elbow, called the " Great Bend," to the mouth 

of its affluent, the Cheinun? River, through a charming, broad valley, bounded 

by soft slopes terminating in wide, table-shaped hills. It is a fertile and very 

beautiful district, and with its westward extension, the plain of the Chemung 

River, is rapidly becoming one of the most attractive agricultural districts of 

New York. From the mouth of the Chemung River to Pittston, where the river 

suddenly turns at a right angle on entering the Wyoming coal field, it flows, with 

many bendings. along a deep and picturesque valley, almost identical in its features with that o" the corresponding stretch of the Delaware, the main difference 

being that the bed of the valley is wider and the hillsides confining it less mountainous. From the mouth of the Lackawanna. at Pittston, where it enters, to 

Nanticoke, where it leaves the beautiful Wyoming Valley, the scenery along the 

river is wholly different. It flows through a broad and almost perfectly level, 

smooth plain the Wyoming and Kingston flats composed of a deep bed of diluvium or drift. On either side of this plain rise the rolling hills of the coal basin, 

and behind these the long, gentle slopes of the high mountain barriers, which 

frame in the whole scene. At Nanticoke the river turns abruptly northward out 

of the coal basin, through its steep barrier, by a highly picturesque pass, and then 

sweeps again as suddenly westward to run for several miles in a closely confined 

trench between the outer and the inner ridges of the basin. It does not, however, 

ran round the western end of this, but at the ravine of the Shickshinny turns 

suddenly southward and cuts across its point, leaving a high, isolated hill of the 

coal strata on its western or right-hand side. Disengaging itself by a fine pass 

from the southern barrier of the coal basin, it passes out into an open valley and 

makes another rectangular bend, to run once more toward the west, parallel with 

the Nescopeck Mountain, which it follows to the neighborhood of Catawissa. 

Beyond this point it maintains its general course westward, somewhat south, 

parallel with the southern base of Montour Ridge, all the way to Northumberland, where it is joined by its great tributary, the West Branch. In some portions 

of this long reach of the river the scenery adjoining it is uncommonly rich and 

pleasing. A remarkably fine view up the river is presented from the hills on its 

west bank, a little below the mouth of Fishing Creek.

WEST BRANCH OF SUSQUEHANNA RIVER.

The drainage basin of the "West Branch has an area of approximately 7,030 square miles, all of which is in Pennsylvania. The 

West Branch has its sources in the mountains of Cambria County at 

an elevation of not less than 2,000 feet above sea level. It flows first 

in a northward direction, receiving some tributaries from Indiana 

County on the west, into Clearfleld County. Gradually bending to 

the right, it flows northeast between Center and Clinton counties, 

east through Clinton and Lycoming counties, and south between 

Union and Northumberland to join the main stream above Sunbury, Pa.

The watershed of this stream occupies the high table-lands of the 

north-central part of Pennsylvania. The crest of the watershed has 

an elevation of from 500 to 1,200 feet above sea level in the vicinity of the junction of the "West Branch and the main stream, increasing to about 2,200 feet at its southwestern part; thence along 

its western side it maintains this latter elevation to its northern line, 

where, in the northern part of the Pine Creek basin, it attains an 

elevation of over 2,600 feet. Along the remainder of the northern 

crest the height quickly falls to about 1,200 feet, but rises again tcT 

about 2,000 feet along the eastern crest of the divide. The highest 

points in the State are along the crest of this watershed.

As far up as Queens Run the fall of this branch is comparatively 

small, while above that point, in the mountain region, it is much 

greater. Furthermore, the banks of both the stream and its tributaries above Queens Run are generally high, and there are few low 

grounds subject to overflow. Below Queens Run the river traverses 

a wide, fertile valley, without, however, overflowing its banks to any 

considerable extent. The bed of the river is generally gravel and 

sand, with a rocky ledge at places. In former years this portion of 

the drainage was largely used by lumbermen for floating logs. On 

most of the streams splash dams were built, sometimes flooding considerable areas, and serving to hold the logs which were sent down 

until a sufficient number were collected. The gates in the dam were 

then raised, letting the water out suddenly, so that the logs were carried down on the swell or wave to the next dam or to the main river, 

where the natural current would be sufficient to carry them along. 

As the forest areas are now largely cut off, but very little logging is 

done either on this or other portions of the river.

Professor Rogers describes this branch of the river as follows: a

The npper part of the West Branch of the Susquehanna, and also its tributaries, the Sinnemahoning, Kettle Creek, Pine Creek, etc., draining the high plateau 

northwest of the Allegheny Mountains, flow through deep trenches in the horizontal strata, very analogous in their features to those which give passage to the 

Delaware and the Main or North Susquehanna, in the northeastern part of the 

State. From the mouth of the Sinnemahoning out into the Bald Eagle Valley,

"Geol. Pennsylvania, p. 49.
24 HYDBOGKAPHY -OF SUSQtIEHANNA BASIN. [NO. 109.

the river hills are very high and steep, and admit extremely narrow strips of 

ground between their feet and the river, except near the openings of the lateral 

streams. The trough through which the lower half of Pine Creek flows is equally 

profound. Entering the valley between the Allegheny Mountains and the Bald 

Eagle ridge, the river pursues a beautiful winding course the whole way from 

Lockhaven to the neighborhood of Muncy, alternately sweeping toward the 

middle of the cultivated valley and back again, close in to the base of the steep 

and wood-covered ridge. Near Muncy it turns with a broad majestic curve 

round the end of the Bald Eagle Mountains, and in a few miles deflects from a 

southwest to a west course, through a highly fertile, richly cultivated open 

country, till it strikes the base of the Blue Hill, or range of red sandstone cliffs 

above Northumberland. Southwest of Muncy the river crosses a singular belt 

of deeply eroded country, full of conical hills.

NAVIGATION.

Information in regard to navigation along Susquehanna River and 

its tributaries is now only of historical interest. The official records of 

Pennsylvania and other papers published during the early part of the 

century show that from the first settlement- Susquehanna River and 

its tributaries were regarded as a possible means of navigation.

In this relation the following quotation from Dager's report is of 

interest: a

General Sullivan, to punish the Six Nations, late in August, 1779. organized a 

force of 3,000 men and moved north from Wyoming, the artillery and stores 

being drawn up the North Branch in 150 boats. At Tioga he was joined by General Clinton with 1,000 New York troops. The latter had marched from Albany 

to Otsego Lake, where, finding the water too low to flo _t his bateaux, he built a 

dam across the stream, by which the lake was raised several feet, and when the 

dam was cut away the discharge wave floated his boats down to Tioga.

The Indians fled in dismay at the sight of a fiood in the midst of the summer 

drought, believing it a signal of the displeasure of the Great Spirit. From this 

might be inferred that Otsego Lake could be made a reservoir to pay tribute to 

the river when there was an insufficient flow.

On March 9, 1777, an act was passed declaring Susquehanna River 

a public highway as far down as Wrights Ferry, and later on, March 

31, 1785, the whole river through Pennsylvania was declared a public 

highway. An appropriation of £6,290 was made as early as April 11, 

1791, for the improvement of the navigation of Susquehanna River. 

Other appropriations were made from time to time and active canals 

were maintained from Havre de Grace to the New York State line, 

on the West Branch from Northumberland to Lock Haven, and on 

the Juniata from Juniata Junction to Holidaysburg.

Between 1800 and 1830 several plans were proposed for connecting 

Susquehanna River with the Great Lakes and with Mississippi River. 

Nothing, however, came of any of these projects, and with the coming of the railroads the canals were gradually abandoned, being in 

most cases bought by the railroad companies. The North Branch 

extension, from the New York State line to Pittston, was abandoned in 

1868 or 1869. The canal from Pittston down was used more or less

a Ann. Rept. Chief of Engineers, U. S Army. 1884, pt. 1, p. 876.

ANDEKSON. MEASUREMENTS OF FLOW. 25

until the fall of 1874, but the high floods of the spring of 1875 caused 

so much damage that 110 boats were run after that date above Wilkesbarre. The L.ickawanna Canal served as a feeder for the Wilkesbarre Branch until the spring of 1882, when it was abandoned to the 

Nanticoke dam. The canals below Sunbury were abandoned about 

1890.

MEASUREMENTS OF FLOW.

The records of the measurements of flow in the Susquehanna drainage have been divided into two classes: First, those at regular stations, where systematic observations have been carried on over a 

series of years; second, those at miscellaneous stations, which consist 

of short or broken series of observations. There have been nine regular stations maintained, as given in the following list:

SUSQUEHANNA RIVER AT BINGHAMTON, N. Y.

This gaging station was established by R. E. Horton July 31, 1901. 

The gage is located on the upstream side of the left span of the 

Washington street bridge. The bench mark is a chiseled draft on 

the corner of the left abutment on the upstream side. Its elevation
'20 HYDROGRAPHY OF SUSQUEHAISTNA BASIN. LNO. 169.

is 23.71 feet above gage datum. This bridge is located about 800 feet 

upstream from the junction of Chenango and Susquehanna rivers. 

A rift extends diagonally across the stream underneath the bridge. 

The gage is above a stretch of smooth water extending from the crest 

of the rift to the dam 2,800 feet upstream, and the gage readings are 

not affected by backwater from Chenango River at ordinary stages. 

On account of unfavorable conditions of Washington Street Bridge 

discharge measurements are made at Exchange Street Bridge, which 

is 1,900 feet upstream. At this place the channel is about 300 feet 

wide at low water and about 450 feet wide at high water, and is straight

for about 500 feet above and below the bridge. The bed is naturally 

gravel and small stones. Formerly a wooden footbridge was located 

at this point, and the channel was divided into three parts by two 

piers. Large stones were piled around the piers. At present a steel 

bridge occupies this site, and there is but one pier, above which are 

two rows of short piles and a quantity of small stones. The upper 

parts of the old piers have been removed, but the stone filling around 

them remains, leaving the river bed irregular and rough.

The velocity is good at low water and swift at high water. The 

lowest observed mean velocity is 0.72 foot per second.

34 HYDROGRAPHY OF SUSQUEHANNA BASIN. [NO. 109. 

CHENANGO RIVER AT BINGHAMTON, N. Y.

This station was established by R. E. Horton July 31, 1901. The 

gage is located on the upstream side of the first span from the right 

bank of Court Street Bridge, Binghamton. It is a boxed wire gage 

secured to the vertical supports of the hand railing. The bench mark 

is a circular chisel draft on the upstream corner of the bridge seat on 

the left abutment. Its elevation is 34.02 feet above gage datum. 

Court Street Bridge stands squarely across the stream, which has a 

nearly horizontal bed of gravel and small cobblestones, affording a 

smooth, uniform current for gaging. The channel is obstructed by 

three masonry piers supporting the four spans of the bridge, 79 feet 

clear width each, the bridge having a total length of 337 feet between 

abutments. The bridge is situated 2,500 feet above" the confluence of 

Chenango and Susquehanna rivers. A small rift below the bridge 

cuts off backwater from the Susquehanna at ordinary stages of the 

rivers. For periods during freshets or at times when there is an 

abnormal rise on one stream, accompanied by a similar rise in the 

other stream, either the Chenango or Susquehanna River record at 

Binghamton may be affected by backwater, indicating a too great 

discharge. For freshets of considerable duration the flow of the two 

streams will be more nearly equalized. Gage readings on Chenango 

River, as well as those on Susquehanna River at Binghamton, are 

taken by E. F. Weeks. In estimating run-off of Chenango River the 

area directly tributary to storage reservoirs from which diversion is 

made to supply Erie Canal has been deducted from the total area 

naturally tributary to Chenango River.

In estimating the run-off of Chenango River the area directly tributary to storage reservoirs, from which diversion is made to supply Erie 

Canal, has been deducted from the total area naturally tributary to 

Chenango River, as follows:

Square miles. 

Natural tributary area «___-_._.__.___.___.__--.---------------.-_---_---.. 1,580

Above estimate of diversion area is approximate. No allowance 

for direct inflow to feeder channels from additional areas nor fo: 

waste into original stream. Gross area, from which more or less runoff is diverted, is about 105 square miles.

a From Bien's Atlas of New York State. Areas tributary to reservoirs are from New York

The daily discharge during January, February, andl March is only approximate, owing to the ice conditions. From March 4 to 23,1904, the discharge was 

estimated from the measurement of March 8, which was approximately 50 per 

cent of normal conditions. This was due to an ice gorge.

SUSQUEHANNA RIVER AT WILKESBARRE, PA.

The Wilkesbarre station was established by E. G. Paul on March 

30, 1899.

The standard chain gage is located on the upstream side of the 

Market Street Bridge. The length of the chain from the end of the 

weight to the marker is 40.83 feet. The gage is read once each day 

by W. S. Bennett, the bridge keeper. When this gage was established, there was found to be a gage painted on the bridge pier, 

being a portion of one established by the Weather Bureau. The 

lower part of this gage, erected in January, 1898^ originally consisted 

of heavy cast-brass plates graduated to feet and tenths. The gage 

plates were made in 4-foot sections and bolted to the stone bridge 

pier. The two lower sections of the brass plates had been torn away 

by ice, so that there was no graduation below the 8-foot mark, but 

readings were made by the figures painted on the stone pier. The 

zero of this old gage is at the base of the dressed-stone portion of the 

pier and is reported to be 535 feet above sea level. During low 

stages of the river the water recedes from the pier, rendering it 

impracticable to read the gage. So far as could be ascertained, this
44 HYDROGRAPHY OF SUSQTTEHANNA BASIN. [so. 109.

has not been connected with the city datum. On account of the low 

water, which in 1897 had gone below the city datum, it was decided 

to put the zero of the new gage 4 feet below the zero of the old 

Weather Bureau gage, so as to obviate minus readings. In order, 

therefore, to compare with former records, it is necessary to add 4 

feet to the old figures. The danger mark of this Weather Bureau 

gage is at 14 feet, or 18 feet of new gage, as at this elevation the 

west bank of the river is under water in places. River reports from 

this locality were furnished as early as 1888. During low water 

measurements were made by wading at a better cross section, at 

Retreat, 10 miles below Wilkesbarre. The elevation of the Market 

Street toll bridge above the river bed requires 65 feet of cable to 

sound across the section.

Observations of fluctuations of Susquehanna River are made by the 

Weather Bureau above Wilkesbarre, at Towanda, Pa., where the 

drainage area is estimated to be 8,000 square miles. The river gage, 

made of iron 1 foot wide and one-half inch thick, is on the east side 

of the road bridge over Susquehanna River, and is securely bolted to 

the masonry of the pier. The graduation is from 0 to 25 feet. The 

highest water was 29 feet in March, 1869, and the lowest, 0.1 foot, 

in October, 1895. The danger line is at 16 feet. The elevation of 

the zero is 633.7 feet.

Discharge measurements are made from the downstream side of the 

bridge, which has a total span of 700 feet between abutments. The 

initial point for soundings is the end of the iron handrail on the left 

bank, downstream side. The channel is straight for about one-fourth 

mile above and below the station. There is a bar across the river 

about one-half mile above the station, and another at about the same 

distance below, with deep water between these two points. This 

makes a, sluggish current at low stages. The right bank is low and 

overflows at a gage height of about 20 feet. The left bank is above 

ordinary floods. The bed of the stream is composed of sand and 

gravel and is somewhat shifting. There is but one channel, broken 

by 3 bridge piers. There are a few willows growing under the right 

span. The bench mark is the extreme west end of the stone doorsill 

of the north entrance to the Coal Exchange Building. Its elevation 

is 32.99 feet above gage datum.

56 HYDEOUEAPHY OF SUSQUEHANNA BASIN. [NO. 109. 

SUSQUEHANNA RIVER AT DANVILLE, PA.

This station, 52 miles below Wilkesbarre and 11 miles above the 

mouth of the West Branch, was established on March 25, 1899, by 

E. Gr. Paul. It is located at the Mill Street Bridge, 600 feet south of 

the public square, Danville, Pa., near the Pennsylvania Railroad station at South Danville. The box of the standard chain gage is bolted 

to the hand rail on the lower side of the bridge 200 feet from the right 

bank. The length from the end of the weight to the marker is 42.85 

feet. The gage is read once each day by E. F. Bell. Discharge measurements were made from the lower side of the Mill street covered 

wooden highway bridge. This bridge was carried away by the ice on 

March 9, 1904. From that time until the water dropped below gage 

height, 5 feet, its stage was observed on the Weather Bureau gage. 

After the water fell below 5 feet its stage was measured approximately, until September 30, 1904, by means of temporary gages set 

by the gage reader. This bridge had a total span of about 1,300 feet. 

The initial point for soundings was at the end of the wooden hand rail 

on the left bank, downstream side. The channel is straight for about 

one-half mile above and below the station. The right bank is low and 

liable to overflow. The left bank is high and is not subject to overflow. The bed of the stream is rocky, with some gravel, and is permanent. There is but one channel, broken by the six bridge piers, 

which do not obstruct the flow to any considerable extent. The current is moderately rapid, except at very low stages, when it becomes 

sluggish. The bench mark is the extreme south end of the stone 

doorsill at the east entrance to the city filter plant. Its elevation is 

31.7 feet above gage datum.

ANDEKSON.J MEASUREMENTS OF FLOW.

WEST BRANCH OF SUSQUEHANNA RIVER AT WILLIAMSPORT, PA.

This station was established March 1, 1895, by George D. Snyder, 

who was at that time city engineer. On August 16, 1901, a standard 

chain gage was installed on the upper side of the Market Street Bridge. 

It is read once each day by Henry H. Guise, who is employed in the 

city engineer's office. The length of the chain from the end of the 

weight to the marker is 40.29 feet. Discharge measurements are made 

from the lower side of the Market street iron highway bridge. The 

initial point for soundings is the face of the abutment on the left bank. 

The channel is straight for several hundred feet above and below the 

station, is broken by four bridge piers, and is about 1,000 feet wide 

at the station. There is a dam about one-half mile above the station. 

Both banks are high and rocky. The bed of the stream is composed 

of gravel and silt, and will probably change to some extent in the 

shore spans. The current velocity is sufficient for accurate measurement, except at extreme low stages. The bench mark is a cut in the

84 HYDROGRAPHY OF SURQUEHANNA BASIN. TNO. 109. 

WEST BRANCH OF SUSQUEHANNA RIVER AT ALLENWOOD, PA.

Observations of height of water on the West Branch have been 

made by the Weather Bureau at Lock Haven, Pa., 47 miles above 

Allenwood. The drainage area is given as 3,740 square miles, and 

the width of river 1,125 feet. The gage is in two sections. The lower 

section is painted on the side wall of the canal lock and the upper is 

on the highway bridge over the river. The elevation of the zero is 

555.7 feet. The highest water was 18 feet, on June 1, 1889, and the 

danger line is at 10 feet.

A gaging station was established on the West Branch by E. G. Paul 

on March 25, 1899, at Allenwood, Pa., 20 miles above the junction 

with the main stream. Measurements are made from the public 

highway bridge, one-fourth of a mile east of the railroad station at 

Allenwood. The wire gage is 42.15 feet from zero to the end of the 

weight, and is referred to a pine-board scale fastened to ironwork of 

the bridge and divided into feet and tenths. The initial point of 

soundings is at the end of the iron guard rail on the right bank. The 

channel is straight for one-half a mile above and below the station. 

The current is sluggish, but unobstructed. The banks are low and 

subject to overflow at time of high water. The bed of the stream is 

rocky and permanent. The observer is Frank L. Alien, a farmer, living 

200 feet from the gage. A bench mark was established on September 

24, 1900. It consists of a copper bolt set in the capstone of the wing 

wall on the lower side of the west end of the bridge, and is 33.19 feet 

above datum of the gage.

This station was discontinued in April, 1902, the station at Williamsport taking its place.

TNDEKSON.] MEASUBEMENTS OF FLOW. 93 

JUNIATA RIVER AT NEWPORT, PA.

Juniata River rises in Center County, Pa., and flows in a general 

southeasterly direction into Susquehanna River 15 miles above Harrisburg. Its drainage area is mountainous and for the most part 

covered with forest growth.

This station was established at Newport, about 15 miles above the 

mouth of Juniata River, March 21,1899, by E. G. Paul. The standard 

boxed chain gage was located ou the covered wagon bridge which was 

800 feet east of the public square at Newport, Pa. It was attached to 

the bridge timbers inside of the bridge near the right bank. The 

length of the chain from the end of the weight to the marker was 39.54 

feet. The gage is read once each day by A. R. Bortel. Bench mark 

No. 1 is on the extreme east end of the stone doorsill, south front of 

Butz's store building, near end of bridge; its elevation is 28.83 feet 

above gage datum. Bench mark No. 2 is on shelf in southeast corner 

of underpinning of store of J. M. Ewing; its elevation is 27.37 feet 

above gage datum. This bench mark was set by the Pennsylvania 

Railroad, and according to their records its elevation is 390.69 feet 

above sea level. Discharge measurements were made from the lower 

side of the four-span wagon bridge to which the gage was attached. 

The initial point for soundings was the end of the woodwork of the 

bridge on the right bank downstream side. In the fall of 1904 this 

bridge was replaced by a steel structure. During its construction the 

stage of the river was obtained by means of a temporary gage staff 

attached to the exposed end of a sewer near the bridge. This gage 

was set at the same elevation as the old one. As soon as the bridge 

is completed a standard chain gage will be put in place. The channel is straight for one-half mile above and below the station. Both 

banks are high and are not subject to overflow. There is a single 

channel, broken by three bridge piers. The piers do not interfere with 

the flow of the stream and there is little eddying and boiling near 

them. The bed is of hard material and is probably permanent. 

There is a good measurable velocity at all stages.

SUSQUEHANNA RIVER AT HARRISBURG, PA.

In 1890 regular daily observations of fluctuations of the water 

surface of the Susqnehanna River at Harrisburg were started by 

E. Mather, president of the Harrisburg water board. These observa-
HOi'T AND") 

ANDEESON.J FLOW OF SUSQUEHANNA AT HARRISBUEG. 105

tions have been continued since that time and have been furnished 

through the courtesy of Mr. Mather.

The gage, the zero of which is the low-water mark of 1803, is located 

at the pump house of the waterworks in the punip well, which is 

connected with the river by two large mains. The original readings 

are taken in feet and inches, and for convenience in computations 

have been reduced to feet and tenths.

The first discharge measurement was made at this station in March, 

1897, by Mr. E. G. Paul, who has carried on systematic measurements there since that date. The measuring section is at the lower 

side of the Walnut street toll bridge. The initial point for soundings 

is the upright at the end of the hand rail on the downstream side on 

the left bank.

At this point the river is divided into two channels by Fosters 

Island, which at the measuring section is about 1,200 feet wide. Its 

banks are low and sloping and during extreme floods the island is 

submerged.

At ordinary stages the left channel is 1,350 feet wide and is broken 

by six bridge piers. The right channel is 1,300 feet wide and is 

broken by seven piers. The main banks of the river are high. The 

bed is composed of a hard material arid is permanent, except in the 

spans adjacent to the island. The velocity never becomes too sluggish to measure.

During the spring and summer of 1903 a new bridge was built 

across Susquehanna River at Market street, which is about 1,200 feet 

below the gaging section. The piers of this new bridge obstruct 

the channel of the river by between 10 and 15 per cent of the total 

cross section. The result of this obstruction, as shown by the discharge measurements taken since the erection of the piers, has been 

to back up the water, thus increasing the gage height at the Walnut 

street station. On account of this backwater the measurements 

taken during 1903 show that, in order to use the standard rating table 

after June 1, 1903, and until January 1, 1904, a deduction of 14 per 

cent is necessary in the daily discharges. The following table gives 

the data from, which this deduction was made:

106 HYDKOGKAPHY OF SUSQUEHANNA BASIN. [NO. 109.

About January 1, 1904, the old piers which were standing at the 

site of the new bridge at Market street were removed, so that the 

river channel was left in such a condition that the stage of the river 

at Walnut street bridge returned to the same condition that existed 

before the 1903 bridge was built.

In the summer of 1904 certain changes and improvements were 

made at the pumping station, and a partial dam was made in the river 

just below the pumping station. The effect of this dam was to raise 

the apparent stage of the water at the gage. A correction was applied 

to measurements of discharge made prior to'July 18, 1904, so as to 

eliminate the effect of the dam and alterations at the pump house 

upon the gage readings.

On July 18, 1904, a standard chain gage was attached to the guard 

rail on the upstream side of the Walnut Street Bridge in the lefthand span. The datum of this gage is the low-water mark of 1803, 

and it is believed that it records truly the stage of the river to that 

datum, and that the changes in bridges below and at the pumping 

station above do not affect the records obtained from it.

The length of chain is 39.38 feet; the bench mark is on the left abutment at the top upstream outer corner of the bridge seat; its elevation 

is 32.99 feet above low water of 1803.

Observations at the gage in the pumping station are made by 

the engineer, 0. M. Nagle, each morning before starting the pump. 

Observations at the standard chain gage are made by Thomas Numbers, toll collector, once daily.

The following pages give the data which have been collected at 

Harrisburg gaging station since its establishment; also the results of 

the computation of these data.

house. From

 ..__> -~ge. Beginning

with April 1 the readings at the pump house were too high by 0.6 toot, owing to the fact that a 

cofferdam was built just below the intake. This correction has been applied; therefore the gage 

readings for the complete year are referred to the low-water datum or 1803. 

& River frozen over at 5 a. m.

< Several ice gorges existed both above and below Harrisburg from January 24 to March 13. 

These caused the backing up of the water, thus increasing the gage height.

"Owing to an ice gorge below Harrjsburg the monthly mean for January, February, and 

March has been estimated by taking 89 per cent of means for McCalls Ferry. Practically open 

conditions existed at the latter station (see p. 183).
130 HYDROGEAPHY OF SUSQUEHANNA BASIN. [NO. 109. 

SUSQUEHANNA RIVER AT McCALLS FERRY, PA.

The McCalls Ferry gaging station is located, as shown in PL VIII, 

at a narrow and rocky part of Susquehanna River, about 20 miles 

above its mouth and 1 mile above the village of that name. It was* 

established on May 17,1902, by Boyd Ehle while investigating a power 

development there. For a considerable distance along this portion of 

the river the bank on the York County shore is the retaining* wall of 

an abandoned canal which can be overtopped only in the greatest 

floods. The Lancaster shore, on the opposite side, is made lip of 

almost vertical rock, and the railroad which skirts it has never yet 

been flooded at this point.

The gaging section first selected for the station is located at Duncans Run (A-A, PL VIII), where two islands, Hartman and Streepers, 

divide the river into three channels, ranging in width from 100 to 500 

feet. At ordinary low water, however, two of these run dry, thus 

confining the discharge to the main or westernmost channel. The 

river bed at the section is composed of schistose rock, with some projecting bowlders and large irregularities. The flow, however, is comparatively free from the boils so common in a river of this character.

The discharge measurements are made from a boat held in place 

by a rope stretched between the towpath and Streepers Island, the 

gaging points, 10 feet apart, being indicated by a tagged wire, which 

is also used for keeping the boat parallel to the current.

In order to provide for measuring the large floods which occur in 

the winter and spring months a cable station was established by Mr. 

Ehle in the fall of 1902, about 1,000 feet downstream from the Duncans Run section (B-B, PL VIII). The banks of the river and the 

condition of the river bed are very similar to those at the upper section, though the latter is somewhat more irregular, as shown by PL 

I, B. During the low-water period of the fall of 1902 a careful survey was made of the section at the cable station, and a contour map 

with 1-foot intervals was prepared from which the effective areas 

could be accurately determined, thus eliminating the error in discharge due to possible inaccuracies in soundings made at the time of 

the measurements. The width of the stream at this point is about 

1,300 feet, and the maximum depth during a gaging was 46 feet.

The car cable, a f-inch 37-wire strand, with a span of 1,450 feet, is 

anchored to 3-inch eyebolts set in cement in the solid rock on either 

side of the river. A 2-inch turn-buckle is provided at the York 

County end to regulate its height above the water. A high cliff on 

one shore and a large red oak on the other give the cable a 10-foot 

clearance over the highest floods on record. The car which runs 011 

the cable, as shown in PL IX, B, accommodates two people, and is 

propelled by a crank turning one of the sheaves.

ANDEESON*.] FLOW OF SUSQUEHANNA AT MYALLS FERRY. 131

Eighty feet upstream from the main cable is suspended a f-inch 

secondary cable, along which runs a trolley carrying a guy rope to 

hold the meter against the current (PI. IX, A). Measuring points 

for this section are 50 feet apart and are indicated by red and white 

bands painted on the main cable, the intermediate distances being 

readily estimated by counting the revolutions of the sheave.

The measurements at both of the above stations are referred to two 

permanent gages, designated Nos. 2 and 5. These are painted on the 

rock and give elevations directly above sea level, (rage No. 2 is 

located about three-fourths of a mile below the village of McCalls 

Ferry in the tailrace of the proposed power house and has been read 

daily since June, 1902. The records in the following tables have 

been referred to this gage. Gage No. 5 is placed about 2 miles 

below McCalls Ferry, at the foot of Cullys Falls, and was thus located 

in order to be entirely out of the influence of the proposed dam. One 

of the purposes of the extensive investigations carried on at McCalls 

Ferry was to obtain data for determining the coefficient of discharge 

over ogee-faced weirs under high heads, and it is for use in these 

investigations that gage No. 5 was established.

The methods used in carrying on the work at the McCalls Ferry 

station were practically the same as those employed by the United 

States Geological Survey. Every effort was made to eliminate any 

source of error, and vertical velocity determinations were taken whenever possible. At Duncans Run, in order to geu satisfactory vertical velocity curves, an 80-pound weight, with pulley and rope 

attached, was dropped to the bottom, so that the meter could be 

pulled down without being washed too far from the section. When 

the surface velocity or 0.6 method was used the results were reduced 

by coefficients determined from these vertical velocity curves. At 

the cable station the secondary cable with the aid of the guy rope 

made it possible to get vertical velocity measurements at exceptionally great velocities and depths. A No. 12 telegraph wire was found 

to be more satisfactory at such times for holding the meter than the 

insulated cable ordinarily used, as it offered less resistance to the 

current, would allow the meter to sink deeper, and being less bowed 

by the water would show more accurately its depth below the surface. In this way curves were obtained to depths of 20 feet and in 

currents of 10 feet per second.

During the highest stages, when the velocity sometimes reaches 17 

feet per second, readings could only be taken at the surface. These 

results were, however, reduced by coefficients determined from the 

vertical velocity curves for each measuring point.

140 HYDROGRAPHY OF SUSQUEHANNA BASIN. FNO. 109. 

CHEMUNG RIVER AT OHEMUNG, N. Y.«

A gaging station was established at the suspension bridge across 

Chemung River near Chenmng station, September 7, 1903. Gage 

heights are taken each morning and night, by Daniel L. Orcutt, by a 

chain gage .attached to the bridge. Current-meter measurements 

which have been made, and the mean daily stage of the stream, are 

shown in the accompanying tables. The gaging station is located 1 

mile upstream from the New York-Pennsylvania line, and is shown 

on the Waverly sheet of the United States Geological Survey's topographic map of the country.

Chemung River is formed at Painted Post, N. Y., by the union of 

Tioga and Cohocton rivers. The Cohocton branch lies entirely in 

the State of New York. Tioga River receives, just above its mouth, 

Canisteo River, a large tributary, which also has its drainage basin 

in New York to the south of the Cohocton. The drainage of Tioga 

River above the Canisteo is mainly in Pennsylvania. The concentration, just above Corning, of the storm waters of these three main 

branches favors the formation of excessive floods.

Chemung River flows southeasterly through Corning, Elmira, and 

Chemung, crosses the State line, flows for a short distance in Pennsylvania, then returns to New York and again crosses to Pennsylvania near Waverly, finally emptying into Susquehanna River near 

Athens, Bradford County, Pa. The total length of the stream is 

about 40 miles, about 30 miles of which is in New York State. Chemung River is a sluggish stream with low banks and a broad valley 

or flood plain, which is often overflowed. It was formerly paralleled 

by a canal taking its supply from dams across the stream. This has 

been abandoned and at present the largest water-power development 

on the main river is at Elmira.

The topographic features of the drainage basin are, as a rule, bold 

and broad. The hills rise within a short distance of the stream 

several hundred feet on either side, and the upland plateau is to a 

large extent wooded, with impervious soil, no lake storage, and few 

marsh areas. Tributaries are ramifying and uniformly distributed, 

though not numerous, and dry gulleys or flood channels are common. 

Dikes have been erected in the cities of Elmira and Corning for protection against floods. One of the highest recorded freshets in the 

stream occurred June 1, 1889. It was preceded by phenomenal rainfall, on the night of May 31 and June 1, aggregating several inches 

in the course of a few hours. The discharge has been estimated at 

67 second-feet per square mile from 2,055 square miles, or 138,000 

cubic feet per second. 6

The above table is applicable only for open-channel conditions. It is based 

upon 8 discharge measurements made during 1903 and 1904. It is fairly well 

denned between gage heights 1.90 and 3.30 feet. The table has been extended 

above gage height 6.70 feet. Above gage height 8.0 feet the rating curve is a 

tangent, the difference being 300 per tenth. The rating table has been applied to 

the nearest hundredth of a foot to gage height 6.00, to the nearest half-tenth of a 

foot to gage height 9.00, to the nearest tenth of a foot above gage height 9.00 

feet.

TIOUGHNIOGA RIVER AT CHENANGO FORKS, N. Y.

During the fall of 1903 the gaging station was established at this 

point in order to determine the low-water flow. Owing to the heavy 

rains which occurred that fall, as shown by the following table, the 

stage of the river did not fall as low as was expected.

gagings, except at extreme high waters. Gage readings were taken 

during October and part of November from a staff gage fastened to 

the right-hand face of the center pier of the bridge. The drainage 

area of Tioughnioga River above the mouth at Chenango Forks, 

including the areas naturally tributary to the Tioughnioga, but now 

diverted to supply Erie Canal through the Erieville and Deruyter 

reservoirs is 735 square miles.

CAYUTA CREEK AT WAVERLY, N. Y.

A record of the daily stage of Cayuta Creek at the Ithaca Street 

Bridge, a short distance below the niilldam in Waverly, was kept by 

T. P. Yates, covering the period March 1, 1898, to March 31, 1902. 

The accompanying tables show the observed distance from the reference point on bridge to water surface, the mean of the several readings being used where more than one daily observation was taken. a 

Discharge measurements by means of floats were also made by Mr. 

Yates.

Cayuta Creek drains a long, narrow valley extending from eastern 

Schuyler County in a direction somewhat east of southerly a distance 

of 30 miles, the stream crossing the New York State line at Waverly 

and emptying into Susquehanna River at Sayre, Pa. In cross section 

the valley consists of a plain about one-half mile wide, through which 

the stream flows, bordered on both sides by abrupt slopes rising 500 

feet within a distance of 1 or 2 miles from the foot on each side,

aReference point is top iron hand rail at left-hand side second iron post from left-hand end of 

bridge on upstream side.
HOYT AND"] 

ANDERSON. J

FLOW OF CAYUTA CREEK AT WAVERLY. 147

beyond which lies a plateau, cut by the numerous short lateral tributaries and their branches.

Cayuta Lake drains an area of 16.5 square miles at the head of the 

stream. The area of the lake is 0.78 square mile, and this constitutes 

the only storage in the drainage basin. The average width of the 

valley is about 6 miles. The conditions favor rapid concentration of 

the run-off in the main stream, there being no large branches. Maximum floods result, however, only from rapid inflow of sufficient duration to enable the waters from the whole length of the valley to reach 

the lower stretches of the stream at the same time. Cayuta Lake is 

at elevation 1,272 feet. The stream descends to elevation 800 feet at 

Waverly in a distance of 18 miles from Cayuta Lake, following the 

general trend of the valley, a limited amount of water power being 

developed at small dams.

CHBNANGO RIVER AT OXFORD, N. Y.

A temporary board gage was attached to the upstream side of the 

left-hand abutment of the highway bridge across Chenango River at 

South Oxford, N. Y., September 29, 1903, and observations of the 

stream stage were taken twice daily from that date until November 

7, 1903. The desired data relative to low-water flow could not be 

obtained on account of heavy rains. The precipitation during the 

period of observation, as recorded at Oxford, is given below:

EATON AND MADISON BROOKS, MADISON COUNTY, N. Y.

Records of the flow of Eaton and Madison brooks, two small streams 

near the headwaters of Chenango River, are among the earliest, if not 

the first, systematic stream gagings in the United States. The flow 

of these streams was determined by John B. Jervis in 1835 in an 

investigation of water supply for the summit level of Chenango 

Canal, extending from Utica to Binghamton, and now abandoned.

Th3 headwaters of Chenango River', including Eaton and Madison 

brooks and the storage reservoirs which have been constructed to 

supply the summit level of Erie Canal through Oriskany Creek, are 

shown on the Morrisville, Cazenovia, Norwich, and Pitcher sheets of 

the United States Geological Survey topographic map.

Eaton Brook drainage basin is from 1| to 3 miles in width and 7 

miles in length. It contains near its head Eaton reservoir, at an elevation of about 1,430 feet. The slopes are steep; the soil is close textured, with shale near the surface. Tributaries are few, and the fall 

is rapid.

The soil and topography of Madison Brook are similar, the area consisting of rounded hill slopes with a somewhat more porous soil, 

greater breadth, and mor,e tributaries than in the Eaton Brook area.

It is stated that the Eaton Brook and Madison Brook gagings show 

only the volume of water passed downstream from the reservoirs.

DIVERSIONS FROM CHENANG0 RIVER DRAINAGE BASIN.

An examination was made of the diversion from Chenango River 

drainage basin to supply Erie Canal during September, 1903.

Proceeding upstream from along the feeder which enters Oriskany 

Creek at Solsville, the draft from the storage reservoirs was observed 

as follows:

Leland Ponds, well drawn down, September 11, 1903, outflow about 

9 second-feet.

Chenango Feeder above inflow from Leland Ponds, September 11, 

1903, about 30 se ond-feet.

Approximate total diversion, 39 second-feet.

The outflow from the several reservoirs proceeding upstream was 

approximately as follows:

Madison reservoir, September 11, 1903, 10 second-feet.

Flow in Chenango feeder at first bridge above Hamilton, also above 

Madison reservoir outlet, about 23 second-feet.

The outflow from the remaining reservoirs in the Chenango River 

area, Kingsley, Bradley Brook, and Eaton reservoirs, respectively, 

was slight. Their combined outflow passes a diverting dam above 

Randalsville, the waste from which, together with waste and seepage 

from the feeder, enters the natural channel of Chenango River. The 

flow in this river channel at the bridge above Earlville September 12, 

1903, was approximately 44 second-feet.

PRECIPITATION.

During the last few years the United States Weather Bureau has 

maintained about 47 precipitation stations in the Susquehanna River 

drainage area (see list on p. 160). The locations of these stations and 

of the gaging stations are indicated in fig. 1 (p. 11).

In order to compare the relation of rainfall to run-off in the Susquehanna basin, the run-off at Harrisburg has been taken as representative of the whole basin, and that at Wilkesbarre and Williamsport as representative of the main stream above Sunbury and the 

West Branch, respectively.

The rainfall stations are so distributed as to represent fairly well 

the conditions over each of these areas. Therefore, it is assumed that 

for any one month the mean rainfall over the whole of any of these 

areas is the mean of the monthly rainfall at the various stations in 

that area. Based upon this assumption, the monthly and yearly 

rainfall for each of the years when the run-off records are available 

has been determined, as shown in tables on pages 161-171.

An examination of the tables on pages 156 and ]57, which give a 

comparison of the rainfall and run-off above Harrisburg, shows that 

the mean annual rainfall over the drainage area varies from 31.4 to

« Snow Of November and December, 1904, on ground.
PRECIPITATION. 155

44.3 inches, with a mean for the fourteen years of 39.4. This yields 

a run-off of from 16.6 to 29.1 inches, with a mean of 21.6. The amount 

of rainfall which runs off varies from 49 to 71 per cent of the total, 

with a mean of 54 per cent. The run-off is a minimum in August, 

September, and October, during which months it ranges from 5 to 30 

per cent of the rainfall, and averages about 15 per cent.

As complete snowfall data are not available, it has been impossible 

to allow for the snow storage, which accounts for the high percentages 

in the late winter and early spring. To fully account for this storage 

a cube of snow should be melted at the end of each month in order 

to determine the amount of water stored during that time. The 

quantity available for run-off during the following month would be 

the amount so determined plus the precipitation during the following month minus the amount left in snow storage at the end of that 

month. Unfortunately sufficient data of this kind are not available, 

and therefore no attempt has been made to account for this disturbing feature.

The tables on pages 158 and 159 show that the conditions on the 

main stream above Wilkesbarre and the West Branch taken separately 

are practically the same as when taken together in connection with 

the entire river as referred to above.

FLOODS.

During the last century there have been several great floods on 

Susquehanna River, the most notable of which are those of March, 

1865; June, 1889 (the Johnstown flood); May, 1894, and March, 1904.

The flood of 1865 was the result of the rapid melting and passing 

away of a large quantity of ice and snow which had accumulated 

during an exceptionally severe winter. The amplitude of this flood 

was probably increased by ice gorges. No information in regard to 

the height of this flood has been obtained except that at the junction 

with the West Branch the river was 2 feet higher than during the 

June flood of 1889; and the old residents along other portions of the 

main river state that this flood was approximately the same as the 

June flood of 1889.

The flood of June, 1889, caused by the heavy rainfall of May 30 to 

June 1, probably exceeded any flood which has ever occurred on this 

stream. Being in the summer months, it was not augmented by ice 

gorges, and therefore illustrates the normal effect of high-water conditions. The table below, taken from the report of the Chief of Engineers, U. S. Army, shows the extent and duration of rainfall within 

the limits of the West Branch; it was upon the high table-lands of 

this portion of the basin that the heaviest precipitation took place.

in the Susquehanna drainage area reaches the outlet of the river. 

It is probable, however, that under extraordinary conditions, such as 

mentioned above, there was a run-off of at least 75 per cent of the 

rainfall.

Various methods of estimating the maximum discharge of the 1889 

flood have been used, perhaps the most reliable indicating that about 

593,000 second-feet flowed past Harrisburg, and 671,000 second-feet 

past McCalls Ferry. The basis of these estimates is shown in Pis. XI 

and XII, the other methods and results being given on pages 177 to 180.

Pis. XI and XII were prepared as follows: The mean velocities for 

the various discharge measurements taken at the respective stations 

were plotted with gage heights as ordinates and mean velocity in feet 

per second as abscissae. Through these points a mean velocity curve 

was drawn and extended to reach the highest gage height of the 

flood. This curve shows the mean velocity for any stage of the 

river. The crest of the 1889 flood at Harrisburg was 27.1 feet 

above the low water of 1803 and at McCalls Ferry cable station 

about 162 feet above mean sea level. The curves show that the 

mean velocities for these heights are 7.24 feet per second and 11.90 

feet per second, respectively. At each of these stations an accurate 

cross section was determined, and the product of the area below the 

flood line and the mean velocity for that gage height, as taken 

from the extended mean velocity curve, gives the flow of the river. 

In this method of estimating flood discharges the uncertainty due to 

the area of the cross section, as when the discharge curve is produced, 

is eliminated. A study of other mean velocity curves made in this 

manner shows that the liability to error in the mean velocity is 

comparatively small, and it is probable that this method gives a 

better estimate than either Kutter's formula or the discharge curve.

The result is a maximum flow at McCall Ferry about 13 per cent 

greater than at Harrisburg, which accords with the assumption that 

the discharge between two points on the same river where the drainage area is similar should increase in proportion to the drainage area. 

At McCalls Ferry the drainage area is 11.4 per cent greater than at 

Harrisburg.

The loss of life caused by the flood within the drainage area of the 

West Branch was 78, and the flood relief commission disbursed 

nearly $300,000 to the sufferers within this district, but no attempt 

was made to secure even an approximate estimate of the damage. 

The flood of May, 1894, near McCalls Ferry was 2 or 3 feet lower than 

the 1889 flood.

The primary cause of the flood of March, 1904, was the breaking up 

of the ice in January without enough water behind it to force it down 

the 1 river. Gorges were formed at various points along the river and
174 HYDROGRAPHY OF SUSQtTEHANlSrA BASIN. [NO. 109.

its branches, which were greatly solidified by the exceptionally cold 

weather in the following month. When the final break came these 

gorges were still further augmented and acted as dams, impounding 

the large quantity of water which was so destructive to property along 

the shores.

On March 6 and 7 there were heavy rains all over the drainage 

area, and on the morning of March 8 the floods so caused began to 

break through the various barriers. It finally forced the big gorges at 

Highspire and Bainbridge, wiping out islands and doing much damage 

in its course.

After the flood had subsided at York Haven, the gorge moved to 

Turkey Hill, where it stood for several hours and backed the water 

to within a few feet of the Columbia Bridge. Between 1 and 2 p. m. 

this gorge in turn gave way and moved to Shanks Ferry, where it 

gorged for the last time. Although it held here for only a few 

moments, it raised the water and ice 6 feet above the railroad track 

at Safe Harbor, completely destroying the stone-arch bridge there 

and leaving ice throughout the village to the height of the second~-story 

windows.

The elevation of the crest of the flood, as shown for a portion of 

the river by the table on page 175, varied in height at various places 

along its course, as compared with the June flood of 1889. At York 

Furnace the height was about 3 feet greater; about a mile above 

McCalls Ferry it was practically the same; at McCalls Ferry station it 

was 3 feet lower, and at the head of Cullys Falls it was again about 

the same height.

There came down with the flood wave a large amount of ice, which 

varied from 3 to 10 feet in thickness, as shown by the blocks left on 

the shores. Owing to the cross currents in the river, the greater portion of the ice went down on the York County side, and it was on this 

side that most of it was left piled up on the shores. The channel on 

the Lancaster County shore soon cleared itself, and but little ice accumulated upon that bank.

The gorge at Turkey Hill broke about 2 o'clock in the afternoon, 

and at 3.30 p. m. the water reached a maximum height at McCalls 

Ferry. At the cable station it was 161.3 feet above sea level on the 

Lancaster County side and 159.8 feet on the York County side. 

Within half an hour from the time the maximum height was reached 

the water had fallen from 2 to 3 feet, and on the morning of March 9 

it had fallen 15 feet.

Between Shanks Ferry and Port Deposit no more ice jams were 

formed, and the ice passed through the channel of the river very 

rapidly and caused but little damage. The history of nearly all 

floods has been that between "The Neck" and Port Deposit but little 

gorging takes place and that the river rapidly clears itself from any

Above Shanks Ferry much damage was done, and the loss of property was great at many points. The facts are interesting to those 

who contemplate power development in the lower portion of Susquehanna River, as the possible damage from ice has been one of the 

great objections to such development.

The full effect of the flood on the main stream was not felt below 

Sunbury, being restrained by the big gorges at Kipps Run, Catawissa, 

and Nanticoke, which held several days longer. It was at its worst" 

in Wyoming Valley on the 9th, doing much damage to Plymouth, 

Wilkesbarre, and Pittston, and then quietly passed away without 

noticeable effect on the lower river.

The cable gaging station about three-fourths mile above McOalls 

Ferry offered a good opportunity for determining the amount of water 

flowing at the maximum stage. At this point two cables are stretched 

across the river 80 feet apart, and at the time of the flood the sun was 

shining in line with these and bright enough to cast their shadows on 

the white ice, thus enabling the determination of the velocity at this 

point with considerable degree of accuracy. The velocity was determined in four different portions of the river, and several individual 

determinations were made in each portion. The result of this measurement is shown in the table below.

FLOOD DISCHARGES Al^D VALUES OF "N" BY KUTTER'S

FORMULA.

Owing to the lack of high-water gagings on Susquehanna River, it 

became necessary to estimate the flood discharges by means of the 

slope formula, v=cVRs, using Kutter's formula to fix the value of c, 

The 1889 flood is the highest on record, and as there remain many of 

its high-water marks made by eyewitnesses along the railroad and 

canal above McCalls Ferry, Pa., the mean slope along this part of the 

river could be closely approximated. These marks consist of notches 

on posts, rocks, hotels, bridge piers, and locks, and their elevations 

were accurately determined, as shown on the profile.

Ten sections, located as shown on PI. XVIII, were then chosen from 

the contour map. These were selected so as to show as far as possible 

the average for the portions of the river represented, so that the mean 

slope between the nearest reliable high-water marks could be used in 

connection with them. The sections were carefully surveyed and 

sounded to determine their area and wetted perimeter.

In order to get a value for n in Kutter's formula the slopes were 

measured on the west channel of the Duncans Run section during

several gagings. With these slopes and the data from the gagings 

made on July 24 aiid 26, 1902, June 5, 1903, and March 8, 1904, the 

coefficients c and n have been computed by the formulas

a At Duncans Eun. '> At section No. 10.

The three measurements at Duncans Run give a coefficient of 

about 0.046. The conditions there are exceptionally favorable for 

this part of the river, so that as the flood sections in many cases 

included brushy and wooded islands, the value of n as used in the 

computations was increased to 0.05.

The data and results showing the discharge at the respective sections during the 1889 flood are shown in table on page 180.

The mean of the discharges of these 10 sections gives a maximum 

for the 1889 flood of about 730,000 second-feet, or 9 per cent greater 

than the mean velocity curve estimate of 671,100 second-feet. (See 

pages 177 and 180.)

In this connection it is of interest to note that if a coefficient equaling 0.055, as determined by the single measurement at section 10, 

based upon the flood gaging of March 8, 1904, had been used, the 

mean discharge for the 1889 flood would have been about 685,000 

second-feet, or only 2 per cent greater than the results obtained by 

using the mean velocity curve.

The general equation of the discharge curve shown on PI. X is 

approximately that of the parabola (y lll)2=. 00202 x, which for a 

gage height of 149.5 gives the 1889 flood discharge as 733,800 secondfeet.

From these estimates it may be assumed that the maximum discharge of the 1889 flood was between 670,000 and 735,000 second-feet.

In determining n at section 10 by means of the flood measurement 

of March 8, 1904, the slope used was between McCalls Ferry and gage 

No. 2, the same points as were taken for the 1889 flood slope, thus 

making the two comparable and indicating that the assumed value 

of w=.05 is on the safe side.

LOW-WATER CONDITIONS.

At the time of the establishment of the gage at Harrisburg, in 1891, 

the lowest-known water on Susquehanna River was in 1803, and 

the zero of the gage was placed at the elevation of this low water.

The months of August and September, 1900, were periods of extreme 

drought, and beginning with the 1st of September the observations 

at Harrisburg showed a gradual falling of the river until September

28-29, when the gage read 0.04 of a foot below the low-water mark of 

ISO-'). During this period of low water Mr. E. G. Paul, hydrographer, 

United States Geological Survey, spent considerable time in measuring 

the flow at the various stations in the Susquehanna drainage basin. 

On September 21 a measurement was made at Harrisburg at a gage 

height of 0.08 of a foot and a discharge of 2,655 second-feet. Mr. 

Paul returned to Harrisburg on September 28, at which date the river 

reached its extreme low point of 0.04 of a foot, and made a measurement giving a discharge of 2,357 second-feet.

The measurements made by Mr. Paul during the week of September 28, 1900, at Allenwood, Danville, and Newport, Pa., as shown by 

the table below, gave a very close check upon the Harrisburg work, 

and show that the measurements as made at the various points along 

the river are consistent among themselves and that no errors greater 

than would be expected in work of this kind exist.

From the best available authorities the elevation of lowest water, 

in September, 1900, at McCalls Ferry, gasre No. 2, was about 112.6 

feet. The measured minimum discharge at Harrisburg for that 

month was 2,357 second-feet, and by increasing this figure 11.4 per 

cent, to allow for the increase in drainage area, we find the corresponding maximum discharge at McCalls Ferry to be about 2,620 

second-feet. In order to check this result, the mean velocities of 

the various discharge measurements made at Duncans Run have 

been plotted as abscissae and their respective gage heights as ordinates, as shown in PI. XIX. These points, it will be seen, seem 

to follow a general law, and a curve has been drawn through them
182 HYDROGBAPHY OP SUSQUEHANNA BASIN. [NO. 109.

which has been extended through the gage height of the lowest 

water, which at Duncans Run was about 114.2 feet. The velocity 

from the curve for that gage height is 1.0 foot per second, and the area 

of the section is 2,940 square feet, the product of these two giving 

a discharge of 2,940 second-feet as a rough check on the above. 

The lowest water actually measured at McCalls Ferry was on September 25,1902, at a gage height on gage No. 2 of 114.34 feet, giving a 

discharge of 6,370 second-feet. The mean discharge from the rating 

table atHarrisburg on that date was 5,760 second-feet, corresponding 

to a difference in drainage area of 10.6 per cent. The table on page 

178 gives the minimum estimated discharge at Harrisburg for the 

years 1891 to 1904, inclusive.

ACCURACY OF STREAM MEASUREMENTS.

Considerable comment has been made upon the hydrographic 

work of the United States Geological Survey on Susquehanna River 

by engineers and others who are promoting power schemes in the 

lower portion of the river, and it was to obtain varying data that 

the late George S. Morison, engineer for the McCalls Ferry project, 

established a gaging station at that point.

As stated on page 130, the McCalls Ferry station was established 

in May, 1902, and during the following year 35 discharge measurements were made at stages which ranged between the highest and 

lowest gage heights during this period. These measurements were 

taken with great care, vertical velocity curves being used in most 

cases. From the measurements a rating curve and table was prepared, by which, in connection with the daily gage heights, both the 

daily and the monthly discharges of the river were computed, as 

shown on pages 137-139.

On comparing the monthly discharges at McCalls Ferry from June 

1,1902, to December 31,1904, as obtained by Mr. Morison's engineers, 

with those obtained by the United States Geological Survey at Harrisburg, as shown in the table on page 183, it is found that the mean 

monthly discharge is approximately between 7 and 25 per cent greater 

at McCalls than at Harrisburg. This difference is what would be 

expected, as the drainage area at McCalls Ferry is 11.4 per cent greater 

than that at Harrisburg.

It is thus seen that the methods of stream measurement used by 

the Geological Survey give results which agree with those obtained by 

private engineers, whose work is generally carried on in greater detail 

and at much greater cost.

An inspection of the discharge curves shows that almost all of the 

individual measurements plot nearly on the curve, very few of them 

varying from it by more than 3 per cent. This fact, while it does not 

prove their accuracy, indicates that the measurements were carefully 

made and that the results are consistent.

184 HYDROGRAPHY OF STTSQUEHANNA BASIN. [NO. 109. 

VERTICAL VELOCITY MEASUREMENTS.

The standard with which all velocity determinations in streammeasurement work are compared is the mean velocity obtained by 

the vertical velocity method. This method consists in taking, in a 

vertical line, a series of velocity determinations, which when plotted 

with depths as ordinates and velocities as abscissae give the basis for 

the construction of a velocity curve along the vertical in question. 

This curve shows the variation in velocity from the surface to the 

bottom of the stream, and from it the mean velocity for the vertical 

can be determined by dividing the area included within the curve by 

the depth. From these curves not only the depth at which the mean 

velocity occurs can be found, but also coefficients for reducing to 

the mean the velocities found at the top, bottom, or at other points.

In the work in the Susquehanna drainage area three series of 

vertical velocity measurements have been made, as follows: At 

McCalls Ferry, Pa.; at Binghamton, IsT. Y., and at Harrisburg, Pa.

The series at McCalls Ferry, Pa., was made during the years 1902 

and 1903 by Messrs. Boyd Ehl'e and R. H. Anderson and consisted of 

73 determinations at the Duncans Run section and 104 measurements 

at the cable section. The depths at the first section varied from 3 to 

30 feet and the mean velocities from 1.2 to 5.8 feet per second. At the 

second section the depths ranged from 3 to 36 feet and the mean 

velocities from 1.2 to 9.7 feet per second. These great depths and 

the high velocities at which these measurements were made make 

them by far the most interesting series of the kind that have been 

made.

The bed of the stream at both of these points is very irregular and 

is made up mostly of solid rock, strewn with large bowlders, as shown 

in PI. I, B, thus making the velocities near the bottom hard to 

determine.

The secondary guy cable with which the station is equipped, as 

noted on page 131 and shown on PI. IX, A, enabled the observer 

to hold the meter at a depth which it is very difficult to reach under 

ordinary conditions.

The results of the measurements have been tabulated and are given 

in the tables on pages 185-187, and the platted curves are shown in 

Pis. XX to XXVI, inclusive.

A study of these tables shows that in order to draw any conclusions 

from the results the individual determinations must be grouped, in 

order to bring together those which were taken under the same conditions. The grouping for the Duncans Run series was made according to depth as follows: Group 1, 4 to 10 feet; group 2, 10 to 20 feet; 

group 3, 20 to 30 feet, and those for the cable station according to 

the distance from the initial point.

Rejecting disturbed and discordant observations, the averages from 

these groups give the results shown in the table on page 188.

mean velocity ranges from about 68 to 72 per cent of the total depth, 

and that holding the meter at 0.6 depth gives a result about 5 per 

cent too large; second, that the coefficient for reducing top velocity 

to mean velocity is practically 92 per cent; third, that the coefficient 

for reducing the mean of the top and bottom velocities to mean velocity ranges from 106 to 118 per cent. The discordance here is due to 

the roughness of bed, which reduces the bottom velocity to a minimum.

depth, and that holding the meter at 0.6 depth gives a result between 

0 and 6 per cent too large, with an average of about 3 per cent. Second, that the coefficient for reducing top to mean velocity ranges 

from about 85 to 93 per cent, with a mean of 90 per cent.

3N.J VERTICAL VELOCITY MEASUREMENTS. 189

From July 1, 1901, to August 15, 1902, Mr. E. C. Murphy made a 

special study of the accuracy of current-meter work and the laws of 

flowing water, on Chenango and Susquehanha rivers, at Binghamton, 

N. Y. A detailed account of these studies can be found in WaterSupply and Irrigation Paper No. 95, from which paper the data used 

in the following are taken.

Figs. 4 and 5 show contours of the bed and position of the piers 

and abutments at the two measuring stations. The Chenango River

FIG. 4. Contour of bottom of Chenango River at Court Street Bridge, Binghamton, N. Y.

station is at Court Street Bridge, Binghamtou, where the observations were taken. The channel there is straight for about 1,000 feet 

on each side of the station, has a width of about 300 feet at low water 

and 340 feet at high water, and is broken by three piers. The bed is 

gravel and cobbles, with large rough stones around the piers. The 

bed is seen to be irregular in shape, as well as rough, but is permanent. The station is about 2,500 feet, from Susquehanna River, and 

is subject to backwater at certain stages. Although the channel is
190 HYDROGRAPHY OF SUSQUEHANNA BASIN. [NO. 109.

broken by three piers, the bridge projects over the piers on each side, 

so that the section of measurement is continuous.

above and below the station, has a width of about 300 feet at low 

water and about 450 feet at high water, broken by 3 piers. The bed 

is of gravel and cobbles, with large irregular-shaped-rock filling 

around the piers. The velocity is rather high, especially at the higher 

stages. About 900 feet above the station is a dam whose height is about 

6 feet.

The methods of work and computations at each station were as follows: The vertical velocity curve observations consisted in measuring velocity at from three to five points in each of the verticals, the 

lowest point being one-half foot above the bed, and the highest 1 foot 

below the surface. Each observation covered four periods of 25 seconds each. The velocities computed from these observations were 

plotted on section paper, and a smooth curve was drawn among these 

called the velocity curve. These points gave, as a rule, a well-defined 

curve, except near the bottom, where the bed was rough.

The curves for each vertical were grouped according to gage height, 

so that the range for each group was not greater than 1 foot. A mean 

vertical velocity curve was then drawn for each group. In making 

these mean curves the means of the velocity at the surface and at each 

two-tenths depth of the original curves were used. The resulting 

mean curves are shown in figs. 6, 7, 8, and 9, and the deductions from 

these are given in the tables headed'' Vertical Velocity Measurements 

on Susquehanna River at Binghamton, N. Y.," and "Vertical 

Velocity Curves on Chenaugo River at Binghamton, N, Y."

In the tables, top velocity means velocity one-half foot below the 

surface, and bottom velocity means velocity one-half foot above the 

bed. Columns 9, 10, and 11 give the mean velocities in each vertical, 

as obtained by three methods, and columns 12, 13, and 14 the coefficients for reducing velocities obtained by either of these methods to 

mean velocity as obtained from the vertical velocity curves,

196 HYDEOGEAPHY OF SUSQlTEHAlSTlSrA BASIN. [NO. 109.

From the curves and table for Chenango River it is seen that the 

value of the coefficient for reducing velocity obtained by the sixtenths-depth method varies from 0.93 to 1.03, the mean being 0.984. 

The coefficient for reducing velocity obtained by the top and bottom 

method to that obtained from the vertical velocity curve varies from 

0.96 to 1.13, the mean being 1.041, the error of this method increasing as the depth increases. The coefficient for reducing velocity 

obtained by the third method to mean velocity obtained from the vertical velocity curve varies from 0.96 to 1.03, the mean being 0.996.

From the curves and table for Susquehanna River it is seen that 

the coefficient for reducing velocity at six-tenths depth to mean velocity obtained from vertical velocity curves varies from 0.95 to 1.06, 

the mean being 0.992. The coefficient for reducing velocity by the 

top and bottom method varies from 1 to 1.17, the mean being 1.068. 

The coefficient for reducing velocity obtained by the third method to 

mean velocity varies from 0.99 to 1.03, the mean being 1.005.

It is seen from the result in these tables: (1) That the third method 

of obtaining mean velocity by observing velocity one-half foot above 

the bed and one-half foot beneath the surface and at mid depth gives 

results agreeing very closely with that obtained from vertical velocity 

curves if the bed is smooth; (2) that results obtained by the top and 

bottom method agree quite closely with those obtained from vertical 

velocity curves if the depth is small and bed smooth, and that the 

error by this method increases as the depth increases; (3) that 

velocities obtained by the six - tenths - depth method are somewhat 

larger than those obtained from vertical velocity curves if the average 

depth is greater than about 4 feet.

The series of vertical velocity measurements made at Harrisburg 

were taken on November 2, 1903. They consisted of 20 measurements at depths ranging from 3 to 8 feet and mean velocity varying 

from 1.5 to 2.6 feet per second. The results of these measurements 

are shown in the following table and by the curves on PL XXVI.

From these observations at Harrisburg we find, first, that the depth 

of the thread of mean velocity ranges from 51 to 72 per cent of the 

total depth and that the mean is 61 per cent. The error, therefore, 

introduced by holding the meter at 0.6 depth is only about 1 per cent. 

Second, the mean coefficient found for reducing top and bottom velocities to mean velocities is 1.08. Third, the coefficient for reducing 

velocities by the integration method to mean velocity is 0.98. Fourth, 

the coefficient for reducing top velocity to mean velocity is 0.85.
198 HYDROGRAPHY OF SUSQUEHAlSnsrA BASIN. FNO. 109.

An interstudy of these various series of vertical velocity measurements shows that at these stations for depths up to about 10 feet and 

velocities not over 5 feet per second the depth of the thread of mean 

velocity is practically 60 per cent of the total depth, while for depths 

over 10 feet and velocities over 5 feet per second the depth of the 

thread of mean velocity becomes greater, averaging about 70 per cent 

of the total depth.

The coefficient for reducing top velocities to mean velocity for 

depths under 10 feet and velocities under 5 feet is about 0.85, while 

for greater depths and velocities it increases to a maximum of about 

0.92.

The top and bottom velocities invariably give too small results, 

depending upon the roughness of the bed.

Furthermore, it is found that although the depth of the thread of 

mean velocity may vary between 50 and 80 per cent of the total depth, 

the error caused by holding the meter at 60 per cent of the depth 

does not exceed 5 or 6 per cent, which is within the limits of the accuracy one can expect in stream-measurement work.

The following table gives a summary of the results of the various 

series of vertical velocity measurements in the Susqehanna drainage:

WATER POWER.

GENERAL DISCUSSION.

In marked contrast to the New England streams, the power 

resources of the Susquehanna River basin, one of the largest draining into the Atlantic Ocean, are little developed.

As shown by the tables on pages 204, 205, taken from schedules furnished by the manufacturers' division of the Twelfth Census, 1900, a 

maximum of 10,375 horsepower is utilized in the portion of the 

drainage area in New York and 38,812 horsepower in Pennsylvania. 

This makes a total of less than 50,000 horsepower an amount which, 

according to the estimates of various engineers, can be developed at 

any of several points on the lower river. By far the greater part of 

this is developed intermittently upon the smaller tributary streams 

by mills of from 20 to 50 horsepower. Pis. XXVIII and XXIX show 

the profile of Susquehanna River and its principal tributaries. These 

profiles are made up from data obtained from the army engineers, the 

report of the Tenth Census, Vol. XVI, and from levels furnished by 

private engineers, as shown in the tables on pages 207-210.

Over the greater portion of the river above Harrisburg the fall per 

mile is from 1 to 2 feet, while below Harrisburg the fall increases to 

between 5 and 8 feet, and it is here that the greatest opportunities 

for large power developments exist. The only point on the entire 

river at which this fall is now being utilized to any great extent is at 

York Haven, where a paper mill uses 2,000 horsepower, and a large 

electric-power plant in course of construction will soon use 10,000 or 

20,000 more.

Mr. W. F. Bay Stewart, of York, Pa., describes the York Haven 

Power Plant, as follows:

The York Haven Water and Power Company's plant is located at the foot of 

the Conewago Falls on the Susquehanna River, ten miles from York and sixteen 

miles below Harrisburg. The natural fall at this point is about 23 feet in about 

three-quarters of a mile. The method of utilizing this fall is by building a wing 

dam out into the river above the falls and turning the greater portion of the flow 

by means of this wing darn within a retaining wall 3,500 feet long, constructed of 

masonry. This wall is built along the river shore just above low water. The 

wall is 16 feet high at the upper end and 32 feet high at the lower end, it is 6 feet 

wide on top all the way. and is built vertical on the inside and with a batter on 

the outside toward the river. The width of the foundation increases with the 

height of the wall, so that at the lower end it is about 22 to 24 feet in width. It 

is built of rubble masonry laid in cement.

The power house begins at the lower end of this wall, and is about 50 feet wide 

and 480 feet long. It contains twenty full-sized chambers and one smaller chamber. The design is to install in each of these chambers two 600-horsepower 

water wheels, and to connect the shafts of these water wheels by means of beveled gears at their top with the shaft of a 750-kilowatt generator, which runs 

horizontally and which is intended to develop at least 1,000 horsepower. To
200 HYBKOGRAPHY OF SUSQUEHANNA BASIN. [NO. 109.

equip the plant will require forty 600-horsepower water wheels and twenty 

generators. In addition to this, in the smaller chamber there will be installed 

two 300-horsepower water wheels which drive two exciters, duplicates, either 

one of which is capable of exciting the whole plant. This building up to a 

height of 34 feet is of the same class of masonry as the retaining wall, and these 

chambers for water wheels are practically openings in an otherwise solid mass 

of masonry 480 feet long by 50 feet wide and 34 feet high. On top of this 

foundation is a brick building, one portion of which is two story and the remaining, one story. In the two-story part the switch boards and controlling devices 

are located. At the lower end of this building and at right angles to it another 

wall is constructed the same height as the high part of the retaining wall and 

about 170 feet long. This wall then extends in an irregular form around the 

buildings of the York Haven Paper Company's plant to the main land. On the 

angle of this wall is constructed a tranformer house sufficient to receive the machinery for transforming all the current generated in the generating plant. The 

current is developed at 2,400 volts and stepped up to 24,000 volts in this transformer house and is transmitted at this voltage to points of consumption. The 

company has built a transmission line capable of transmitting 6,000 horsepower 

from York Haven to York, where another transformer house has been built capable of transforming 24,000 volt current down to 2,200 volts, at which voltage it 

will be delivered to customers. It is the purpose of the company to build a like 

transmission line to Harrisburg, with a like transformer house at that city, and, 

possibly, also to Lancaster, Pa., which is about 20 miles from the plant. The 

machinery installed and to be installed in this plant is capable of an overload 

of 25 per cent, thus increasing the capacity to 25,000 horsepower, and of course 

it could be more largely increased by raising the head.

Between York Haven and the mouth of the river there is a fall of 

about 270 feet. The mean annual discharge at York Haven from 

1891 to 1904, inclusive, is about 40,000 second-feet. By applying the 

rule that 11 second-feet of water falling 1 foot equals a horsepower 

with 80 per cent efficiency it is seen that between York Haven and 

the outlet of the river there about one million horsepower running 

to waste, though several neighboring cities would afford an eager 

market for all that could be developed. There are, of course, several 

obstacles in the way of development, perhaps the most serious of 

which would be the occasional ice freshets and gorges, making substantial protective works necessary and reducing or obliterating the 

available head. Between the narrows above McCalls Ferry and Port 

Deposit, however, the ice passes down through either a deep or a 

broad channel, with no tendency to gorge and seldom doing damage. 

At present there are several individuals and companies who are promoting power schemes on the lower river, and a large plant at York 

Haven has recently been completed.

Mr. II. F. Labelle, who spent several years in the study of the 

power possibilities of the lower Susquehanna, states the following in 

regard to the power developments on the lower Susquehanna River:

The bed of the stream from Columbia to Port Deposit is for the most part 

very wide, varying from 3,500 feet to about 2^ miles opposite Washingtonboro. 

There are, however, a few "narrows/ 1 as at Conowingo and McCalls Ferry. The 

stream being wide and rapid, it naturally follows that at low water it is verj 

shallow and can be forded in many places. The water in the narrows is, how-
WATEB POWER. 201

ever, very deep. At Conowingo Bridge, on the west side, there is a narrow chanrel over one-half mile long in which depths of 75 feet have been found. At 

r^.cCalls Ferry, where the river narrows to about 300 feet, the depth is also considerable. These deep channels are also met here and there on the wider parts of 

1 he river namely, between Turkey Hill and Star Rock station, on the east side, 

^here depths of over 90 feet have been found.

The Susquehanna and Tide-water canal skirts the west side of the river from 

"^rightsville to Havre de Grace. Before the building of the Philadelphia, Baltimore and Washington Railroad and the Frederick Branch of the Pennsylvania 

Pailroad this canal had a brisk carrying trade, chiefly in coal from the anthracite regions. The flood of June, 1889, wrecked the canal in many places. The 

cost of repairs was very high, and the canal continued in operation until May, 

:'894, when another flood caused considerable damage to the property. Since that 

time it has been practically out of operation. After changing hands several 

times, it was finally bought by the Susquehanna Electric Power Company, of 

Baltimore. This company is about to begin the construction of their first plant, 

1 olow Peach Bottom. The Frederick Branch of the Pennsylvania Railroad runs 

en the west side of the river from Columbia to Perryville, where it connects with 

the main line of the Philadelphia, Baltimore and Washington Railroad.

The minimum discharge of the river at Shures Landing can be taken safely at 

fi ,000 second-feet. This would give a minimum gross power to be developed from 

Columbia to tide water of 153,000 horsepower. The proposed plants, however, 

] ave been designed for a supply of 10,000 second-feet, which is available most of 

the time.

This would give a possible power of about 255.000 horsepower. This available 

power can almost be totally utilized, and the writer knows of projects on the 

river aggregating over 185,000 horsepower.

The power available on the Susquehanna has at its disposal a much better 

market than any other in the United States, not barring Niagara Falls. Baltimore is a little more than 40 miles from the half of the minimum power and Philadelphia is within 65 miles of the two lower plants, taking on the way Wilmington, with its heavy power consumption.

The upper plants are within easy reach of Lancaster, York, Harrisburg, Readmg, and other manufacturing centers. Eastern Pennsylvania, with its great 

manufacturing activity, will surely avail itself of whatever amount of power can 

1 x e developed on the river, and towns like Havre de Grace (10 miles below Shures 

Landing), located on two of the large trunk lines between the North and the 

fouth and also at the head of Chesapeake Bay, can be transformed by cheap 

power into manufacturing centers of no mean importance.

There is no doubt that with the help of steam plants and there are many 

already established in the larger cities of the district 400,000 horsepower could be 

f eveloped on the river below Columbia and find a ready and remunerative market.

Starting from tide water the principal plants projected are as follows: (1) Conr wingo plant, 25,000 to 35,000 horsepower; (2) the Peach Bottom plant, 40,000 horsepower; (3) the Fites-Eddy plant, 40,000 horsepower; (4) the York Furnace, McOalls Ferry plant, 45,000 horsepower; (5) the Turkey Hill plant, 30,000 horsepower.

There is about 9 feet fall available below the Conowingo works, but it is 

1 elieved that the conclitious would not make it advisable to develop any power at 

that point.

At Conowingo the powerhouse is located a short distance above Shures Landing. 

The building extends for a distance of about 500 feet, square across the stream 

from the west shore. The original development is to be of 25,000 horsepower, but 

provision is made in the power house for the development of 10,000 additional 

horsepower. From the river end of the power house the dam extends upstream
202 HYDROGRAPHY OF SUSQUEHANNA BASIN. [NO. 109.

a distance of 1,300 feet, the crest being at an elevation of 50.5 feet. The dam then 

turns toward the foot of McDowells Island, 800 feet away; thence it follows the 

center of McDowells Island for 3,600 feet to its head, and thence it goes diagonally 

to the east shore, a distance of 2,600 feet. The last 7,000 feet have their crest Fit 

an elevation of 43 feet, except 200 feet close to the high part of the dam, where a 

spillway for ice has been located, its crest being at an elevation of 41 feet. A 

needle dam will close this spillway at ordinary stages. The river above 

McDowells Island is over ?»,000 feet wide and the dam forms a pool over 4 miles 

long. It has a sufficient rollway to pass the highest known floods without 

endangering the riparian property above it. The high part of the dam and tl o 

McDowells Island section are 8 feet wide on the crest. The remainder of the dam 

has a crest 12 feet wide. The whole dam will be of rubble, with ashlar facing en 

the downstream side. Borings have shown that a continuous rock bottom will 

be obtained on McDowells Island at an average depth of 11 feet. The generatirg 

plant will probably be divided into 1,250 kilowatt units. The turbines will 1 3 

vertical, with draft tube. One pair of turbines will serve each dynamo, the connection between turbines and horizontal shaft of dynamo being made by two 

crown wheels engaging bevel gears on this shaft.

The working head will be 34 feet at low water and 30 feet at ordinary stages.

The Turkey Hill plant is located between Turkey Hill and Safe Harbor, on tl ? 

east side of the river. At Turkey Hill the river is about 1 mile wide, and a low 

diverting dam about 5 feet high will form a large pond above it. This pond 

extends to Columbia, a distance of 5 miles, and its width varies between 1 and 24 

miles. The head and tail race canals are formed by an embankment paralleling 

the railroad track and forming a canal varying from 190 to 250 feet in width at 

the bottom. This embankment is about 3 miles long. It is composed of a riv}r 

wall in cement battering li inch per foot on the river side and 2^ inches on the 

back. Next to this is the loose rock embankment proper, 40 wide on top and 

sloping 1 to 1 on the power-canal side. This mode of construction will meet the 

impact of the ice and prevent it from overtopping the embankment. At the main 

dam, and close to the head works, there will be a raft chute and a raft channel 

leading from it and close to the embankment 011 the river side. The average 

working head will be 30 feet, and the power house will be located at Star Rock.

DURATION OF THE STAGES OF THE LOWER SUSQUEHANNA.

In order to show the mean conditions and the duration of flow whi^n 

have existed on the lower Susquehanna River during the last twelve 

years 1891 to 1902, inclusive the curves in PL XXVII have been constructed. The dotted-line curve is plotted with gage heights as ordinates, and with the number of days during the mean year on which tl x<3 

stage of the river was less than the given gage height as abscissae. 

The full-line curve shows the number of days during the mer.n 

year when the discharge was below any given amor nt. In the preparation of these curves the Harrisburg gage heights for each year, as 

shown on pages 108 to 114, were tabulated according to magi>iV '»de. 

The number of days during the year when the water stood at eaefi 

height were then tabulated, and from these the number of days during 

the year when the river was lower than the various gage heights was 

determined. The curves were constructed from the mean of these yearly 

tables, and in the case of the full-line curve the discharges as :given 

in the rating table on page 115 were substituted for the gage heights.

S?DEESON.] WATEE POWER. 203

To use the two curves in conjunction with each other, enter the 

diagram with a certain gage height, find where it intersects the gageheight curve, then follow the ordinate of this intersection until it cuts 

the discharge curve, and the discharge for that particular gage height 

is found on the right side of the diagram.

Assuming that the discharges at the various points in this portion of 

the river vary in proportion to the drainage area above, one can readily 

determine by the use of the curves the conditions which may reasonably be expected at any point below Harrisburg. For example, suppose one wishes to know how many days during the mean year the 

discharge will be less than 5,500 second-feet at the PennsylvaniaMaryland line, where the drainage area is 27,150 square miles, or 13 

per cent more than at Harrisburg. As the drainage area at Harrisburg is 88.6 per cent of that at the State line, 5,500 second-feet would 

correspond to a discharge of 4,870 second-feet at Harrisburg. From 

the full-line curve on PL XXVII we find that for twenty days during the 

mean year the discharge is less than 4,870 second-feet at Harrisburg, 

or 5,500 second-feet at the Maryland-Pennsylvania line.

By applying the following simple rule for horsepower it is possible 

to determine the probable power which could be developed during a 

mean year at any point in the lower Susquehanna:

Rule: Horsepower on the turbine shaft equals the discharge in second-feet multiplied by the fall divided by 11. This is based upon an 

assumption of 80 per cent efficiency for the turbines.

Applying this to the above example, we find that for three hundred 

and forty-five days during the mean year 500 horsepower for 80 per 

cent efficiency can be developed for each foot fall at the MarylandPennsylvania line.

RULES FOR ESTIMATING DISCHARGE.

The approximate mean monthly discharge in second-feet for any 

stream in the Susquehanna drainage basin, may be determined in 

either of two ways 

First. Its drainage area in square miles can be taken from the 

table on page 15, or measured on a map, and multiplied by the 

monthly run-off in second-feet per square mile given in the tables of 

the nearest gaging station.

Second. The monthly rainfall in inches for the district, as determined from, the tables on pages 161 to 171, can be multiplied by the 

per cent of run-off for that month at the nearest of the three gaging 

stations Wilkesbarre, Williamsport, or Harrisburg giving the total 

monthly run-off in inches. This result multiplied by one of the following coefficients gives the mean monthly run-off in second-feet per 

square mile:

For month of SSdays.-.-. .............................................. 0.9603

For month of 30 days...--..-.-.---....--........-.....-.-.........-..--. .8963

For month of 81 days................................................... .8674
204 HYDROGRAPHY OF SUSQUEHANNA BASEST. [NO. 109.

The drainage area in square miles may be found as before, and 

if multiplied by the above product will give the mean discharge of 

the stream for that month in second-feet.

The horsepower may then be computed by the rule on page 203.
