The data for the preceding estimate are not very complete, but 

 it is believed that the sum of $3,000,000 is large enough to meet 

 somewhat adverse conditions. 



The construction of Schroon valley reservoir as here proposed 

 would submerge several villages, of which the cost is included in 

 land damages. 



With a total storage of 21,662,000,000 cubic feet and total cost 

 of |3,000,000, the cost per million cubic feet stored becomes 

 roundly $138.50. In the same way the cost per million gallons 

 stored becomes about $18.50. , 



Schroon valley reservoir no in jury to waterpower on Hudson 

 river. The foregoing discussion of Schroon valley reservoir pro- 

 ject shows that not only may all injury to existing waterpower 

 in Schroon valley be obviated, but that 10,639 gross horsepower 

 may be permanently created there. With Hadley dam ulti- 

 mately constructed, as proposed in the upper Hudson report of 

 1895, there would be Stillwater in Hudson river from mouth of 

 Schroon river to Hadley. Inasmuch as Hadley dam is intended 

 as a regulator of upper Hudson reservoir system, without any 

 special waterpower development connected therewith, no injury 

 to waterpower above Hadley on account of diversion of 775 

 cubic feet per second would occur. But from the regulating dam 

 down the Hudson river waterpowers would suffer, but not to 

 the extent of the value of 775 cubic feet per second for the whole 

 year. Broadly, the proposition takes this form: On account of 

 large temporary storage on Schroon, Brant and Paradox lakes, 

 the mean summer flow of Schroon river is higher than it would 

 otherwise be for the given catchment area. Taking into account 

 this natural advantage, what injury can be done to Hudson river 

 waterpowers from Hadley to Troy by the continuous diversion 

 of 775 cubic feet per second, the quantity so diverted to be 

 drawn, not from the natural flow of the river, but from a large 

 storage reservoir substantially regulating the entire flow for a 

 series of years? 



In answering this question we must take into account the 

 character of the waterpower development on Hudson river. 

 The most of it is 24-hour power used for pulp-grinding and paper- 

 making. Pulp may be ground in high-water flow and stored for 

 use in months of minimum ilow. This circumstance has led to
