The diversion of water for the use of Champlain canal is an 

 injury to the waterpower at Glens Falls and lower points on the 

 river. Since waterpower is much cheaper than steampower, 

 the taking of the water of the river away from the manufac- 

 turers is a serious matter. In the fourteen years from 1882 to 

 1895 the use of waterpower on Hudson river increased 237 per 

 cent. 



The upper Hudson storage system is estimated to cost in 1904 

 from $80 to flOO per million cubic feet stored, a sum consider- 

 ably less than the cost of many other systems. 



Storage Reservoirs on Schroon River 



In 1900 the writer reported to the Merchants' Association of 

 New York in regard to a reservoir for a water supply to that 

 city to be located on Schroon river. The scope of this report 

 was as follows: 



1) The discussion of a project for supplying five hundred 

 million (500,000.000) gallons daily (775 cubic feet per second) 

 of pure water from a single large reservoir to be located on 

 Schroon river. 



2) The supplying of the same quantity from Lake George and 

 Schroon river. 



3) In addition to the storage reservoirs, from which the city 

 supply of pure water would be drawn, these two projects further 

 included compensating reservoirs large enough to compensate 

 for amount of water abstracted for supply of Greater New York. 



4) The discussion of a project for supplying a large quantity 

 of stored water to Hudson river, in order to hold the point of 

 upward flow of salt water through tidal action as far down 

 stream as practicable. 



The following are the main points embodied in the report to 

 the Merchants' Association: 



Schroon river Hows into Hudson river just above Thurman 

 bridge and about fifteen miles north of Hadley. The catchment 

 area at its mouth is 570 square miles. It issues from a region 

 with a permanent population of from 12 to 14 per square mile. 

 The prevailing rocks are granitic, with large areas of fine sand; 

 there are only limited swamp areas.
