About the delaware river


The Delaware River is a major river on the east coast of the United States, spanning approximately 330 miles from its source in the Catskill Mountains of New York to its mouth at the Delaware Bay. The river has played a significant role in American history, serving as a boundary during colonial times and as a major shipping route during the industrial revolution. The Delaware River has a complex hydrology system with many tributaries and large reservoirs, including the Pepacton, Cannonsville, and Neversink reservoirs in New York, and the Blue Marsh Lake in Pennsylvania. These reservoirs provide drinking water for millions of people in the region. The river is also used for recreational activities such as fishing, boating, and hiking, and supports agricultural activities in the surrounding areas.
