If Schroon river water is taken into conduit just above mouth 

 of stream, the sewage of Warrensburg village and the manufac- 

 turing establishments would be properly carried in a close conduit 

 or pipe to a point below the diversion weir. The estimates for 

 sanitary protection include the cost of the necessary special 

 constructions for this purpose. 



There is considerable summer population about Schroon, Brant, 

 Paradox and other lakes of Schroon area, and the estimates for 

 sanitary protection further include cost of properly caring for 

 waste products at hotels, cottages, etc. 



The following presents the main points of comparison for dams 

 at Tumblehead falls, storing 13.5 and 18.0 inches on the catchment 

 area, respectively :

By reference to the United States Geological Survey's topo- 

 graphic sheets, the significance of these figures may be easily 

 appreciated. 



In order to insure thorough control of the margins, it is sug- 

 gested that an area of 50 square miles should be taken. The 

 estimate includes such taking. 



The following is the estimated cost of constructing Schroon 

 valley pure water reservoir and diversion weir, with necessary 

 gate houses, sanitary protection and other special constructions : 



Land damages f 1,000,000 



Clearing and stripping 500,000 



Dam at Tumblehead falls 600,000 



Diversion weir 250,000 



Sanitary protection 300,000 



Miscellaenous 350,000 



Amount $3,000,000
