where it is feasible to develop a reservoir with capacity of 

 7,000,000,000 cubic feet. The object of this reservoir was ta 

 provide storage within reasonable distance of the main deep 

 waterway, so that in case of temporary stoppage of the main 

 feeder to the north, water could still be supplied to the canal. 

 The hight of the main dam on Salmon river was about 56 feet. 

 In addition to this there were three dykes, cutting off lateral 

 valleys at different points of the reservoir. 



On Black river also a reservoir was surveyed for the Board of 

 Engineers on Deep Waterways for a main water supply for the 

 proposed canal. When constructed this reservoir will be the 

 largest in the State. The water surface at Carthage will be 

 raised 48.5 feet and an area flooded at extreme high water of 

 nearly 78 square miles, or roundly 50,000 acres. The cubic con- 

 tent of the reservoir at high water will be nearly 70,000,000,000 

 cubic feet, and at spillway crest over 57,000,000,000 cubic feet. 

 The area flooded at spillway crest will be 73.2 square miles and 

 13.6 inches stored on the tributary catchment of 1812 square 

 miles. 



Extended studies were also made in 1895-96 of the possibility 

 of water storage on the Hudson river, where the waterpower has 

 increased from less than 13,000 horsepower in 1882 to something 

 like 50,000 horsepower at the beginning of 1898 and to about 

 80,000 horsepower in 1901. The Legislature failed to make an 

 appropriation in 1897 and these studies have never been com- 

 pleted, although considerable addition to the information has 

 been made since that time. The studies so far as carried show 

 that it is possible to create on the Hudson river a continuous per- 

 manent power of about 175,000 horsepower, and undoubtedly 

 when the studies are completed it will appear that considerably 

 more than this can be developed at a cost which will be com- 

 mercially feasible. Probably at least 210,000 horsepower can 

 be commercially developed. 



In 1900, in a report to the Merchants' Association of New 

 York, a large reservoir on Schroon river, with capacity of 21,662,- 

 000,000 cubic feel, was proposed. This reservoir had been form- 

 erly proposed as the Tumblehead reservoir of the Hudson sys- 

 tem, but the original proposition was to make it of a storage 

 capacity of 16,246.000,000 cubic feet.
