HYDROLOGY OF NEW YORK 



485 



A high-water mark at the Newport dam indicates a flood dis- 

 charge on August 25, 189S, of 22,000 cubic feet per second (catch- 

 ment, 472 square miles) , or at the rate of 47 cubic feet per second 

 per square mile. 



At Middleville the flood of August 25, 1898, is estimated to have 

 discharged 12,950 cubic feet per second (catchment, 519 square 

 miles), or the flow was at the rate of 25 cubic feet per second per 

 square mile. 



In August, 1874, a flood at Hinckley is estimated at 21,100 

 cubic feet per second (catchment, 360 square miles), or at the 

 rate of 59 cubic feet per second per square mile. It is probable 

 that flood flows as high as from 60 to 70 cubic feet per second per 

 square mile are rather common in West Canada creek. # 



Flaods in Sauquoit creel-. The figures for this stream are not 

 very definite, but so far as they go they indicate that floods of 50 

 cubic feet per second per square mile are not uncommon. 



Floods in Oriskany creel-. In the spring of 1888 a flood is re- 

 ported in this stream as measured at Coleman of 7830 cubic feet 

 per second (catchment, 141 square miles), or at the rate of 56 

 cubic feet per second per square mile. 



In the spring of 1896 a flood is also reported in this stream, as 

 measured at Oriskany, of 7510 cubic feet per second (catchment, 

 144 square miles), or at the rate of 52 cubic feet per second per 

 square mile. Ordinary floods in this stream range from 18 to 25 

 cubic feet per second per square mile. 



Floods in Nine Mile creel-. On August 25, 1898, there was a 

 flood-flow at Stittsville for a short time of 7820 cubic feet per 

 second (catchment, 63 square miles), or the stream flowed at the 

 rate of 125 cubic feet per second per square mile. 



On March 12, 1898. the flow at Stittsville was 1800 cubic feet 

 per second, or at the rate of 29 cubic feet per second per square 

 mile. 



Floods in Allegheny river. Nothing is known in regard to the 

 flood-flows of Allegheny river and its tributaries any further than 

 that the tributaries in their upper portions have heavy flows. As 

 an estimate, purely, many of them may be placed at from 60 to 70 

 cubic feet per second per square mile, but like streams in other 

 parts of the State, they need to be studied on their merits.
