Delaware River

Delaware River
River in Pennsylvania and Delaware, U.S. Formed by the junction of its eastern and western branches in southern New York, it flows some 280 mi (451 km) to empty into the Atlantic Ocean at Delaware Bay.

Navigable to Trenton, N.J., it is spanned by the Commodore John Barry Bridge (1,644 ft [500 m] long), completed in 1974.

 river of the Atlantic slope of the United States, meeting tidewater at Trenton, N.J., about 130 miles (210 km) above its mouth. Its total length (including the longest branch) is about 405 miles (650 km), and the river drains an area of 11,440 square miles (29,630 square km). The river constitutes in part the boundary between Pennsylvania and New York, the boundary between New Jersey and Pennsylvania, and, for a few miles, the boundary between Delaware and New Jersey. The river's course is basically to the south.

      The main, or west, branch rises in Schoharie county, N.Y., at a point 1,886 feet (575 m) above sea level. The river cuts deeply through a plateau until it emerges from the Catskill Mountains. Leaving the mountains and plateau, the river flows down Appalachian valleys, skirts the Kittatinny Mountains, which it crosses at Delaware Water Gap (a national recreation area) between nearly vertical walls of sandstone, and passes through an area of farms and forests until it enters hills again at Easton, Pa. From this point, it is flanked at intervals by hills and in places by cliffs, including the Nockamixon Rocks, 3 miles (5 km) long and more than 200 feet (60 m) high. At Trenton there is a fall of 8 feet (2 m).

      Below Trenton the river becomes a broad, sluggish inlet of the sea, with many marshes along its side, widening into its estuary, Delaware Bay. Its main tributaries in New York are the Mongaup and Neversink rivers; in Pennsylvania, the Lehigh and Schuylkill rivers; and in New Jersey, the Musconetcong and Maurice rivers. Major cities along the Delaware include Port Jervis (N.Y.); Easton, Philadelphia, and Chester (Pa.); Trenton and Camden (N.J.); and Wilmington (Del.).

      Commerce was important on the upper course of the river before the beginning of railway competition (1857). Of the various early canals only two continued to be of any importance—the canal from Trenton to New Brunswick, uniting the Delaware and Raritan rivers, and the canal joining the Delaware River with Chesapeake Bay. The Interstate Commission on the Delaware River Basin was formed in 1936 by the four states in the watershed of the river (New York, New Jersey, Pennsylvania, and Delaware) to control and prevent water pollution, plan the conservation of water supply for the use of the cities, and plan development along the course of the entire river. To facilitate traffic on the river, channels have been dredged from the deep water in Delaware Bay to Philadelphia and from Philadelphia to Trenton.

      On Christmas night of 1776, George Washington and about 2,400 of his soldiers crossed the Delaware from Pennsylvania to New Jersey 9 miles (14 km) above Trenton and successfully surprised British Hessian troops in their winter quarters at Trenton.
