one mile north of Prattsville; one mile north of Lexington, and 

 at Kaaterskill Junction. On the Batavia kill, they are located 

 at the following: Just north of Ashland and Windham and south 

 of Big Hollow; and on the East kill, below East Jewett. These 

 reservoirs would afford about 40,000,000,000 gallons (5,400,000,000 

 cubic feet) of available storage, and would yield in minimum 

 years, according to the writer's estimate, about 500,000 gallons 

 of water per square mile per day. The dam at Gilboa would be of 

 masonry — the others of earth, with spillways cut in the rock 

 sides of the valley. 



Waterpowers on Schoharie creek above Prattsville are unim- 

 portant, consisting of but two or three small sawmills. There 

 are several powers at and -below Gilboa, but none of them is very 

 important, although the abstraction of the water from Scho- 

 harie creek would affect all the powers on the Mohawk river below 

 the mouth of the Schoharie. 



Basing a calculation on the power developed at Cohoes in rela- 

 tion to the low-water flow of the stream, the effect of the abstrac- 

 tion of the proposed amount of Schoharie creek water would be 

 about 1800 horsepower. 



Table No. 1)1 gives the particulars of storage reservoirs on 

 Schoharie creek.
