preferable. The quality of Lake George water — the same as 

 Schroon river — is unexceptionable. 



Reservoir system for river regulation only. This project pro- 

 poses the development of storage on headwaters of the Hudson 

 river in order to hold low-water flow at as high a point as possible, 

 thereby driving salt water further downstream and consequently 

 permitting of taking a supply from the lower Hudson by pumping 

 lower down than would otherwise be possible. 



In the first report on the upper Hudson surveys it is shown that 

 a reservoir system may be developed capable of maintaining a flow 

 at Mechanicville of 4500 cubic feet per second. The following 

 tabulation gives the main elements of such a system of reservoirs 

 so far as worked out, together with the approximate cost of the 

 same, all based on 13.5 inches on the catchment except Schroon 

 valley, which is taken at 18 inches :

The capacity of Indian lake reservoir of about 5,000,000,000 

 cubic feet should be added to the foregoing total of 51,728,000,000 

 cubic feet, giving a final total of 56,728,000,000 cubic feet. Fur- 

 ther examination will probably show that a somewhat greater 

 storage can be obtained, but thus far the data for final con- 

 clusions have not been gathered. A moderate amount of storage 

 may also be constructed on headwaters of Mohawk river, but
