List of Delaware River tributaries
The watershed of the Delaware River drains an area of and encompasses 42 counties and 838 municipalities in five U.S. states—New York, New Jersey, Pennsylvania, Maryland, and Delaware. This total area constitutes approximately 0.4% of the land mass in the United States. The Delaware River rises in New York's Catskill Mountains flowing southward for 419 miles into Delaware Bay where its waters enter the Atlantic Ocean near Cape May in New Jersey and Cape Henlopen in Delaware. There are 216 tributary streams and creeks—an estimated 14,057 miles of streams and creeks—in the watershed.
The waters of the Delaware River's basin are used to sustain "fishing, transportation, power, cooling, recreation, and other industrial and residential purposes." While the watershed is home to 4.17 million people according to the 2000 Federal Census, these bodies of water provide drinking water to 17 million people—roughly 10% of the population of the United States. It is the 33rd largest river in the United States in terms of flow, but the nation's most heavily used rivers in daily volume of tonnage. The average annual flow rate of the Delaware is 11,700 cubic feet per second at Trenton, New Jersey.

Tributaries in Delaware
Tributaries of Delaware Bay
The shores of the bay are largely composed of salt marshes and mud flats, with only small communities inhabiting the shore of the lower bay. Besides the Delaware, it is fed by numerous smaller streams. Several of the rivers hold protected status for the unique salt marsh wetlands along the shore of the bay. The bay serves as a breeding ground for many aquatic species, including horseshoe crabs. The bay is also a prime oystering ground. The Delaware Bay was designated a Ramsar Wetland of International Importance on May 20, 1992. Further, it was the first site classified in the Western Hemisphere Shorebird Reserve Network.
