The area between Starbuckville and Tumblehead falls not 

 available with the system of small reservoirs is 23.3 square miles. 



The total controllable area of the upper Hudson, with the 

 system of small reservoirs in the Schroon valley, is as follows: 



Square 

 miles 



Sacandaga valley 190 



Hudson above Hadley 514 



Schroon valley 4 ~$ 



Total 1,183 



With one large reservoir in Schroon valley, the total catch- 

 ment area is increased to 1206 square miles. 



The system of small reservoirs outlined in the foregoing is 

 estimated to store 15,330,000,000 cubic feet, at a cost of $1,172,- 

 500; hence, the cost per million cubic feet stored becomes $76.48. 

 These figures, however, do not take into account the actual cost 

 of maintenance and operation, which may be placed at $30,000 

 per year and capitalized at 5 per cent, is equivalent to a perma- 

 nent investment of $600,000. Adding $600,000 to $1,172,500 

 gives a total permanent investment of $1,772,500.
