Discharge measurements of Chittenangq creek. Gagings of 

 this creek have been made at the mill-dam at Bridgeport, a short 

 distance above its mouth. Gage readings were taken three 

 times a day, showing the hight of water above crest of dam, 

 head on wheels and width of gate openings. The dam is of tim- 

 ber, backed with stone, and has a nearly level crest, 215 feet 

 long, with flood gates at the ends. Figure 21 shows a section 

 of this dam. 



The relatively low runoff of Chittenango creek during the 

 summer months may be attributed to the diversion of a portion 

 of the flow to supply the Rome level of Erie canal. For this 



purpose State dams are situated on the main stream at Chitte- 

 nango and on its two tributaries, Limestone and Butternut 

 creeks. Cazenovia lake, Erieville, De Ruyter and Jamesville 

 reservoirs are situated on these streams. 



The Erieville reservoir has a tributary catchment of 5.4 square 

 miles. The storage capacity is 318.425,000 cubic feet, and the 

 water surface 340 acres. 



Cazenovia lake has a tributary catchment of 8.7 square miles. 

 The storage capacity is 207.000,000 cubic feet and the area of 

 water surface 1.7 square mijes. 



De Ruyter reservoir has a tributary catchment area of 18.5 

 square miles, which is naturally tributary to Tioughnioga river, 

 a tributary of Chenango river. The storage capacity is 504.500.- 

 000 cubic feet and the area of water surface 626 acres. The out- 

 flow is diverted into Limestone creek, entering Erie canal 

 through Fayetteville feeder.
