Kensico Reservoir
 The Kensico Reservoir is a reservoir located in the towns of Armonk (North Castle) Harrison and Valhalla (Mount Pleasant) New York that was put into service in 1915. It is about 3 miles (5 km) north of downtown White Plains New York and about 15 miles (24 km) north of New York City. It was formed by the Kensico Dam impounding the Bronx River but receives most of its water from other sources.
