To the west of Little Falls lies 19.2 miles of the eastern division, 

 supplied from the reservoirs and streams of the middle division. 

 East of Little Falls the supply is from Mohawk river, through 

 Little Falls, Rocky rift, and Rexford Flats feeders, and from 

 Schoharie creek through Schoharie creek feeder. As to the quan- 

 tity of water used on that portion of Erie canal included in the 

 eastern division very little is known. With the exception of a few 

 thousand cubic feet per minute received from the_ middle division, 

 the supply is, as just indicated, all derived from the Mohawk river 

 and its tributary, Schoharie creek. Thus far no measurements of 

 the actual quantity used have been made. Probably the total 

 diversion amounts in dry weather to from 400 to 500 cubic feet 

 per second. Some of this is returned to the Mohawk river by leak- 

 age and wastage, but just what proportion is returned, and what 

 Anally delivered either into the Hudson river at Albany or by the 

 Troy and Fort Schuyler side cuts, is not known. In view of the 

 magnitude of the power development on the Mohawk river at 

 Cohoes it appears very desirable that such a determination be 

 made. • 



The water supply of the Champlain canal is derived from Wood 

 creek and several small streams to the north of Fort Edward. 

 Glens Falls feeder, Hudson river feeder, from the Hudson river 

 itself at Saratoga dam, and from the Mohawk river at the Cohoes 

 dam. 



As already stated, the Champlain canal is fed from the Hudson 

 river by the Glens Falls feeder, which connects with the river 

 about 2 miles above Glens Falls and from the Saratoga dam ;U 

 Northumberland.
