Overview of the Delaware River
The Delaware River is a vital waterway in the northeastern United States, stretching about 579 kilometers (360 miles) from its source in New York State to its mouth in the Delaware Bay, where it meets the Atlantic Ocean. The river serves as a natural border between Pennsylvania and New Jersey and provides drinking water to millions of people.
Where is the Delaware River on the map?
The Delaware River begins in the Catskill Mountains of New York, then flows through Pennsylvania, New Jersey, and Delaware, before emptying into the Delaware Bay. It is one of the few major rivers in the U.S. that remains undammed along its mainstem, allowing for a free-flowing ecosystem.
Historical significance
The Delaware River is famous for its role in American history. On December 25, 1776, General George Washington led his troops across the icy river in a surprise attack against British forces in Trenton, New Jersey—a key moment in the American Revolution.
