face from 17 to 20 feet. The taking of an additional strip, for 

 sanitary protection, as in Schroon valley, would include nearly all 

 of these, as well as the village of Caldwell. 



Basing the Lake George project on 775 cubic feet per second 

 supply, the same as for Schroon valley, it is found tlmt from 300 

 to 350 cubic feet per second would come from the Lake George 

 catchment area. The balance can be obtained from Schroon 

 ralley by a tunnel through the intervening ridge ait a point above 

 Warrensburg, where the distance across is only 3.25 miles (17,160 

 linear feet). A diversion weir with proper regulating head- 

 works would be required on Schroon river. The elevation of 

 Schroon river at the point of diversion is about 670 feet. With 

 Lake George taken! at 323 feet, the difference becomes 347 fecit. 



For several months of each year the runoff of Schroon river 

 exceeds 550 cubic feet per second, the mean runoff for four years 

 being 1112 cubic feet per second. Hence, a mean' of 550 cubic 

 feet per second could be diverted into Lake George and still leave 

 Hudson river waterpowers substantially unimpaired. The con- 

 necting tunnel should therefore have a capacity of about 2600 

 to 2800 cubic feet per second in order to divert the full flood-flows. 



The following is an approximate estimate of cost of Lake George 

 storage with diversion tunnel from Schroon valley, etc. : 



Land damages, Lake George $1,500,000 



Dam at foot of Lake George 200,000 



Water rights on Lake George outlet 2,000,000 



Sanitary protection 400,000 



Clearing and stripping 300,000 



Diversion weir and headworks on Schroon river. . . . 100,000 



Diversion tunnel 1,500,000 



Compensation reservoirs 200,000 



IVIiscellaneous 500,000 



Total $6,700,000 



A comparison of this estimate with the foregoing for Schroon 

 vialley project fairly lends bo the conclusion that independent of 

 lack of elevation at Lake George, the Schroon valley project is
