Why We Care

The main stem of the Delaware River is the longest undammed river east of the Mississippi, traveling 300 miles from its headwaters in Hancock, NY down to the Delaware Estuary and Bay.  The Watershed spans New York, Pennsylvania, New Jersey, and Delaware through one of the most densely populated areas of the mid-Atlantic region. 

Within the Watershed’s boundaries are roughly one million acres of wetlands and about 50 percent is forested. Significant ecological and recreational assets include the Delaware Water Gap National Recreation Area (one of the country’s most visited national parks, the more than 400 miles of waterways designated under the National Wild and Scenic Rivers program), six National Wildlife Refuges, and the highly complex Delaware Estuary, which is one of the most important shorebird migration sites in the world. 

This vast river system not only provides vital habitats for a rich variety of fish and wildlife species, but it's also home to more than 8 million residents, provides drinking water to an estimated 13.3 million people, and is critical to the economic well-being of the mid-Atlantic region.

This national treasure is remarkable for its wealth of natural resources, but it remains vulnerable to environmental threats. That's why the Coalition was formed. By uniting groups across the region, the Coalition is creating a cleaner, healthier watershed for generations to come.
