HYDROLOGY OF NEW YORK 



The length of the Glens Falls feeder, from the guard lock at its 

 head to where it enters the Champlain canal, about 2 miles above 

 Fort Edward, is 6.92 miles. From this point the water in the 

 canal flows both north and south, the total length of the canal fed 

 by the Glens Falls feeder being 31.81 miles. Fort Edward level, 

 into which the Glens Falls feeder delivers water, is a summit level, 

 and hence the water delivered into it, less the losses by percola- 

 tion, evaporation, etc., is partly discharged into Lake Champlain 

 and partly into the Hudson river at the Saratoga dam. The Cham- 

 plain canal crosses through the pond formed by the Saratoga dam 

 from the east side to the west of the Hudson and again passes out 

 of the river, taking a full supply therefrom at the village of North- 

 umberland, from which point to the Mohawk river at Cohoes the

distance is 27.06 miles. The water from this section by passing 

 into the Mohawk finally reaches the Hudson above the Troy dam. 

 The canal crosses the Mohawk river at Cohoes, taking water there- 

 from to supply the section from Cohoes to near West Troy, a 

 distance of 2.3(3 miles. A small amount of water also passes 

 from the Champlain canal to the Hudson through the Waterford 

 side cut. 



Since the construction of the Glens Falls feeder there have 

 existed serious leaks through the seamy limestone rock in which 

 the feeder is excavated at and below the village of Glens Falls. 

 It is claimed that the losses through these seams have generally 

 increased, until for several years past they have amounted to 

 about 50 per cent of the total flow into the feeder at the guard 

 lock. 



This leakage has been repeatedly complained of by the owners 

 of waterpower at Glens Falls and several attempts to check it 

 have been made, but without much avail. The river falls 38 feet 

 at Glens Falls, and the owners of the waterpower there claim
