Lake DeForest

Lake DeForest, also called DeForest Lake, is a reservoir in Clarkstown, New York, created in 1956 by impounding the Hackensack River, which is a principal part of the water supply for Rockland County, New York and Northern New Jersey, mainly Bergen and Hudson counties. The reservoir is owned and operated by Suez North America, and is the most upstream of its reservoirs along the river's watershed, the others being Lake Tappan, the Woodcliff Lake Reservoir, and the Oradell Reservoir. It has a storage capacity of 5.6 billion gallons. Swimming and bathing are disallowed because the water is reserved for potable use. The lake is traversed by a causeway carrying Congers Road (CR 80).
