Site of Old Croton Dam is a historic dam site located at Cortlandt, Westchester County, New York. The dam was built between 1837 and 1842 and was the first substantial masonry dam in the United States. Construction of the dam was delayed by a January 1841 storm that washed away most of the dam.^[2][3][4]

A gravity dam constructed with a rubble core and granite ashlar foundation, it was 57 feet (17 m) high and 670 feet (200 m) long. The dam was linked to the Old Croton Aqueduct to form part of the original New York City water supply system. When the New Croton Dam was constructed in 1906, the old dam was submerged. When the reservoir is full, the old dam is submerged to 34 feet (10 m).^[5][6]

It was added to the National Register of Historic Places in 1973.^[1]
