The Muscoot Reservoir is a reservoir in the New York City water supply system in northern Westchester County, New York, located directly north of the village of Katonah.

Part of the system's Croton Watershed, it is 25 miles (40 kilometres) north of the City.

From there it enters the New Croton Aqueduct and flows south into the Jerome Park Reservoir in The Bronx.

[2] Water from the Croton Aqueduct is distributed within the city to parts of The Bronx, Manhattan, and western Queens.
