The New Croton Dam is a dam forming the New Croton Reservoir, both parts of the New York City water supply system. It stretches across the Croton River near Croton-on-Hudson, New York, about 22 miles (35 km) north of New York City.

New York City water supply system
A combination of aqueducts, reservoirs, and tunnels supplies fresh water to New York City. With three major water systems stretching up to 125 miles (201 km) away from the city, its water supply system is one of the most extensive municipal water systems in the world.

Prior to being levelled around 1811 it was located near the current intersection of Mott and Grand Streets. New York City, which then extended to a stockade which ran approximately north–southeast from today's Chambers Street and Broadway, is visible beyond the southern shore.
