Cross River Reservoir

Located in northeastern Westchester County, about a mile east of the Village of Katonah, and more than 25 miles from New York City. Formed by the damming of the Cross River, which then continues west and drains into the Muscoot Reservoir. Consists of one basin, approximately 3.2 miles in length. Holds 10.3 billion gallons at full capacity. Placed into service in 1908.

The Cross River is one of 12 reservoirs in the City’s Croton system. Water withdrawn from the reservoir’s western tip flows into the continuation of Cross River, empties into the Muscoot Reservoir, and from there flows to the New Croton Reservoir for further settling. After travelling through the 24-mile New Croton Aqueduct, the water reaches the Jerome Park Reservoir in the Bronx, where it enters New York City’s distribution system.

The Cross River Reservoir watershed’s drainage basin is 30 square miles and includes portions of the Towns of Bedford, Lewisboro and Pound Ridge in Westchester County, and a small part of Fairfield County, Connecticut.
