Catskill Aqueduct

The Catskill Aqueduct is an aqueduct in the New York City water supply system which brings water from the Catskill Mountains to Kensico Dam in Westchester County, New York. There it joins with waters from the Kensico watershed and the Delaware Aqueduct. After mixing and settling, the flow from Kensico continues in the aqueduct to the Hillview Reservoir in Yonkers for distribution in the City.

The 92-mile (148 km) aqueduct is fed by the waters of the Schoharie and Ashokan reservoirs located in Ulster County.
