# Croton River watershed

This page is about the Croton River watershed, a hydrological feature. For the component of the New York City water supply system with a similar name, see Croton Watershed
The Croton River watershed is the drainage basin of the Croton River and its seven tributary rivers, a hydrological feature in southeastern New York State. Spanning large swaths of Putnam and Westchester counties, it is over 350 square miles (910 km$^2$) in area and holds some 115 billion US gallons (440,000,000 m$^3$) of fresh water.
Largely physically overlapping the New York City water supply system's Croton Watershed, the Croton River watershed represents the drainage and flow of some seven rivers, one dozen reservoirs, three controlled lakes, large Lake Mahopac, and countless smaller lakes and ponds.
The vast majority of this water ends up at the Jerome Park Reservoir in the Bronx via the New Croton Aqueduct, from which it is distributed to New York City. Water in excess of the City's needs spills over the New Croton Dam at the New Croton Reservoir and is carried by the Croton River into the Hudson River at Croton-on-Hudson, New York, about 30 miles north of the Metropolitan area.

## Definition

The Croton River watershed is a hydrological feature, the 361 sq mi (930 km$^2$) drainage basin of the Croton River and its tributaries. It is not synonymous with the Croton Watershed, a term describing the rivers, reservoirs, dams, pump systems, and other infrastructure of the southernmost watershed of the New York City water supply system. Numerous small natural lakes and ponds, as well as large Lake Mahopac, are within the river's watershed but not owned, leased, or controlled by the City water supply system (even though they too ultimately drain into it). A map of the actual Croton Watershed is found here.
The Croton River (/ˈkroʊtən/ KROH-tən) is a river in southern New York with three principal tributaries: the West Branch, Middle Branch, and East Branch. Their waters, all part of the City water supply system, join downstream from the Croton Falls Reservoir. Together, their waters and the reservoirs linked to them represent the northern half of the New York City water system's Croton Watershed.
Shortly after the confluence of the three Croton River branches the Croton River proper, along with its tributary, the Muscoot River, flow into the Muscoot Reservoir, after which it empties into the New Croton Reservoir, which feeds the New Croton Aqueduct supplying water to New York City via the Jerome Park Reservoir in the Bronx. Excess water leaves the spillway at the New Croton Dam and empties into the Hudson River at Croton-on-Hudson, New York at Croton Point, about 30 miles (50 km) north of New York City.
