Located in north central Westchester County, just north of the Village of Katonah, more than 25 miles from New York City. Formed by the damming of the upper half of the Croton River, which ultimately empties into the Hudson River at Croton Point. Consists of one narrow, river-like basin, which stretches almost 8 miles and adjoins the New Croton Reservoir, which is south/southwest of the Muscoot. Holds 4.9 billion gallons at full capacity. Placed into service in 1905.
The Muscoot is one of 12 reservoirs in the City’s Croton system. It receives water from all other Croton reservoirs with the exception of New Croton Reservoir, and passes those waters into the New Croton. There the water enters the New Croton Aqueduct for the last leg of the southbound journey into New York City’s water distribution system at the Jerome Park Reservoir in the Bronx. Originally, water from the Muscoot was released into the New Croton at the Muscoot Dam. That dam, near Katonah, is now submerged and the two reservoirs form one long lake.
The Muscoot also receives water from its own watershed, which has a drainage basin of 76 square miles and includes portions of the Towns of Bedford, Lewisboro, North Salem, Pound Ridge, Somers and Yorktown.
