the control of the Superintendent of Public Works. The object 

 of constructing it was to store flood water to be turned into the 

 Hudson river during the low-water period of each year, thereby 

 equalizing the flow. The fact that the Champlain canal takes 

 water from the Hudson river through the Glens Falls feeder was 

 the reason why the State considered it necessary to control this 

 dam. The catchment area above the dam is 116 square miles. 

 The storage cost is at the rate of $20 per million cubic feet stored. 1 

 Cedar river. This river rises in Cedar lake in the central part 

 of Hamilton county at an elevation of about 2530 feet above tide, 

 and flows northeasterly, generally parallel to Indian lake and 

 river, entering the Hudson river two miles north of Indian river. 

 There is no water-power development upon this stream, but there 

 is a reservoir of considerable capacity at Wakeley, at an elevation 

 of about 2000 feet above tide. 



Mohawk River 



Mohawk river, the largest tributary of the Hudson, rises in the 

 western central part of the State, near the Lewis and Oneida 

 county line. It flows in a southerly direction to the city of Rome, 

 from which it takes an easterly course across the State, emptying 

 into the Hudson a little above Troy. The principal tributaries 

 are Schoharie, East Canada. West Canada and Oriskany creeks, 

 while less important tributaries are Chuctenunda, Cayadutta, 

 Garoga and Sauqnoit creeks and Lansing kill. There are a num- 

 ber of small streams, several of which are utilized as water sup- 

 plies for the villages of the Mohawk valley. 



The following are the elevations above tidewater of a number of 

 points along the Mohawk river:
