The following detail in regard to the preceding feeders and 

 reservoirs is condensed from the Barge Canal Report. 



Oriskany feeder. This 'feeder has a catchment area above the 

 diversion dam at Oriskany of 234 square miles, which includes 87 

 square miles of the catchment of Chenango river, therefore leav- 

 ing 147 square miles tributary to Oriskany creek. On the Che- 

 nango river catchment there are a number of reservoirs, a list 

 of which lias been given on page 417. 



Mohawk- feeder. A short distance east of the Black River 

 canal a portion of the Mohawk river is diverted by the Mohawk 

 feeder into the Erie canal. The catchment area of the river above 

 the point of diversion is 156 square miles. It is thus without 

 water storage. The minimum flow of the Mohawk river at Ridge 

 Mills, as shown on a preceding page, is rather large, although it 

 should not be overlooked that it receives the waste and leakage 

 of twenty-five miles of the Black River canal. For the present it 

 may be taken at 0.2 cubic foot per second per square mile.

Black river canal feeder. The Erie canal is supplied with 183 

 cubic feet per second of water from the Black river canal, which 

 unites therewith at Rome. The summit level of the Black river 

 canal is supplied from Black river at Forestport by means of a 

 navigable feeder about 10.5 miles in length. The distance from 

 Boonville to Rome is about twenty-five miles. 



The pond at the head of the Forestport feeder is formed by a 

 diversion dam across Black river, a short distance below Wood- 

 hull creek. The catchment area at the diversion dam is 2C>7 

 square miles. The Forestport reservoir is on Black river about 

 1.5 miles above the diversion dam. This reservoir has an area of
