HYDROLOGY OP NEW YORK

Grasse river. The next stream is Grasse river, which drains a 

 long, narrow catchment area lying between Oswegatchie and 

 Raquette rivers. The channel of Grasse river is parallel to the St 

 Lawrence throughout the whole eighteen miles of its course. For 

 several miles it is separated from the St Lawrence by a neck 

 of land about four miles in width. The Long Sault rapids of 

 the St Lawrence river, comprising a fall of about 50 feet, occur 

 within this reach. This fact has been taken advantage of for 

 the construction of an hydraulic power plant by the St Lawrence 

 Power Company. A canal, three and one-half miles in length, 

 has been cut across the divide, by which water is diverted from 

 near the head of the rapids to a power plant on the bank of 

 Grasse river. After using, the water is turned into Grasse river 

 for a tail-race; 35,000 horsepower is developed under a head 

 of 42 feet. The catchment area of Grasse river above Canton 

 is 113 square miles and 637 square miles above its mouth.

 cipal developed water powers on Grasse river, but not including 

 the large power plant at Massena :
