Amawalk Reservoir

Amawalk

Located in north central Westchester County, at the intersections of Routes 202 and 35, more than 25 miles north of New York City. Formed by the damming of the Muscoot River, a tributary of the Croton River, which continues east to the Muscoot Reservoir. Consists of one basin, approximately 3 miles long. Holds 6.7 billion gallons at full capacity. Placed into service in 1897.

The Amawalk is one of 12 reservoirs in the City’s Croton Water Supply System. Water from the Amawalk Reservoir flows into the continuation of the Muscoot River and then into the Muscoot Reservoir. The Amawalk also receives water from Kirk Lake, one of the three controlled lakes in the Croton system, which travels south via a stream to reach the reservoir. From the Muscoot, it travels to the New Croton Reservoir. It leaves the New Croton Reservoir through the New Croton Aqueduct, which carries it to the Jerome Park Reservoir in the Bronx, where Croton system water enters New York City’s distribution system.

The Amawalk watershed’s drainage basin is 20 square miles and includes portions of the Town of Somers in Westchester and the Town of Carmel in Putnam County.
