The Neversink River (also called Neversink Creek in its upper course) is a tributary of the Delaware River, approximately 65 mi (105 km) long, in southeastern New York in the United States. The name of the river comes from an Algonquin language phrase meaning "mad river."
It rises in the Catskill Mountains, in Catskill State Park in northern Sullivan County. It flows generally south through the mountains, past Woodbourne and into western Orange County. At Otisville it is joined from the northeast by Basher Kill, then flows southwest, joining the Delaware at Port Jervis, near the common boundary of New York, New Jersey, and Pennsylvania.
In its upper course near Neversink, it is impounded to form the Neversink Reservoir. It is connected by 5 mi (8 km) water tunnel to Roudout Reservoir, and subsequently to the Delaware Aqueduct.
The Delaware River is a river on the Atlantic coast of the United States.
Its main tributaries in New York are Mongaup[?] and Neversinkrivers[?] and Callicoon Creek[?]; from Pennsylvania, Lackawaxen[?], Lehigh[?], and Schuylkill rivers[?]; and from New Jersey, Rancocas Creek[?] and Musconetcong[?] and Maurice rivers[?].
A canal from Trenton to New Brunswick, called the Delaware & Raritan Canal, unites the waters of the Delaware and Raritan rivers; the Morris and the Delaware and Hudson canals connect the Delaware and Hudson rivers; and the Delaware and Chesapeake canal joins the waters of the Delaware with those of the Chesapeake Bay.
River in Pennsylvania, Delaware, New Jersey, and New York, U.S. Formed by the junction of its eastern and western branches in southern New York, it flows about 405 mi (650 km) to empty into the Atlantic Ocean at Delaware Bay.
The Delaware River constitutes in part the boundary between Pennsylvania and New York, the entire boundary between New Jersey and Pennsylvania, and the entire boundary between Delaware and New Jersey.
The Morris Canal and the Delaware and Hudson Canal connect the Delaware and Hudson rivers.
