is 77.1 square miles. That of Erieville reservoir and Oazenovia 

 lake combined is 14.1 square miles. 



Fayetteville feeder. A portion of the water of Limestone creek 

 is diverted into the Fayetteville feeder at Fayetteville. This feeder 

 is 1.2 miles long- and is navigable for 0.83 of a mile. Xear Delphi, 

 Limestone creek divides into two branches. De Ruyter reser- 

 voir is located at the head of the branch from the south. This 

 reservoir is formed by an earth dam 70 feet high, and has a 

 storage capacity of 504,468,000 cubic feet, with an average area 

 of 620 acres and depth of 18.5 feet. It impounds water from

18.2 square miles of the catchment of Tioughnioga river. Its 

 location is 15 miles southeasterly from the head of the diver- 

 sion dam at Fayetteville, and the intermediate catchment is 



77.1 square miles. The total catchment above Fayetteville is 



95.2 square miles; below this village the feeder intercepts 

 Bishops brook, 'with a catchment of &3 square miles. The total 

 catchment area tributary to the Fayetteville feeder is therefore 

 103.5 square miles. 



The storage capacity of De Ruyter reservoir is at the rate 

 of 27,800,000 cubic feet per square mile of tributary catchment, 

 as figured on the basis of 18.2 square miles of catchment area. 



Orrville feeder. At a point 2.2 miles south of the canal at 

 De Witt the water of Butternut creek is diverted through the 

 Orrville feeder into the canal. Jamesville reservoir. 2.4 miles 

 above the head of the feeder, is formed by a dam across the 

 creek. The area of the reservoir formed is 252 acres; average
