Cannonsville Reservoir
The Cannonsville Reservoir is a reservoir in the New York City water supply system in Delaware County, New York. It was formed by construction of the Cannonsville Dam on its west end, which empounded over half of the West Branch of the Delaware River. Lying on the western part of the Delaware Watershed, it is the westernmost of New York City's reservoirs. It was placed in service in 1964, and is the most recently constructed New York City-owned reservoir.
The town of Cannonsvile was destroyed to make room for the reservoir, which lies within the towns of Tompkins and Deposit.
Its drainage basin is the largest of all of the NYC reservoirs. Capacity is. Water from the reservoir flows into the West Delaware Tunnel in Tompkins, New York. Then it flows through the aqueduct into the Rondout Reservoir, before joining the Delaware Aqueduct, which provides New York City with about 50% of its drinking water.
The Delaware Aqueduct then crosses beneath the Hudson River and continues on to the West Branch Reservoir in Putnam County, New York, then the Kensico Reservoir in Westchester County, both north of the City. It then continues further south to the Hillview Reservoir in Yonkers, where it joins the flows of the Catskill and New Croton aqueducts for distribution through the New York City tunnel system.
The Cannonsville Dam is being considered as a site for a 14.08MW hydroelectric generating station.Tributaries
