HYDROLOGY OF NEW YORK

Without going further into detail, the following may be given 

 as the approximate storage of the upper Hudson system, worked 

 out to 1904. 1 



Cubic feet 



Storage of Sacandaga and main Hudson river 

 catchment areas, not including Boreas river 

 reservoir, Boreas pond, Indian lake, and Piseco 



lake 14,364,000,000 



Boreas river reservoir and Boreas pond 1,111,000,000 



Indian lake 2 4,468,000,000 



Piseco lake 1,725,000,000 



Schroon valley 15,925,000,000 



Hadley 4,000,000,000 



Oonklinville 10,000,000,000 



Total 51,593,000,000 



This storage is considered sufficient, in conjunction with the 

 natural flow of the unregulated portion of the river, to maintain 

 at Mechanicville a flow of at least 4,500 cubic feet per second 

 during the entire year. 



The general investigations indicate that there is an oppor- 

 tunity to make a large reservoir on Sacandaga river by the erec- 

 tion of a dam at Oonklinville. The available storage of such a 

 reservoir is from 8,000,000,000 to 10,000,000,000 cubic feet. It is 

 taken in the preceding tabulation at 10,000,000,000 cubic feet. 



There is also an opportunity to construct on the main Hudson 

 at Hadley, just above the mouth of the Sacandaga, another 

 reservoir of about 4,000,000,000 cubic feet capacity at a point 

 where the natural conditions for constructing such a reservoir 

 are good. At the site of the proposed dam the river shows a 

 granitic rock bottom, with precipitous banks nearly forty feet 

 in hight and about one hundred feet apart. The material for a

 Upper Hudson Storage Surveys, in Annual Reports of State Engineer and 

 Surveyor for the Years 1895 and 1896. Also, refer to Report to Merchants' 

 Ass. of New York, 1900. 



2 The storage of this reservoir with the fiashboards in place is taken at 

 5.000,000.000 cubic feet.
