Get to know your watershed! The Alliance for Watershed Education of the Delaware River is comprised of 23 environmental education centers in New Jersey, Pennsylvania, and Delaware. The Delaware River is the longest undammed river east of the Mississippi, and its watershed stretches all the way into upstate New York, providing clean drinking water for more than 15 million people – that’s nearly 5% of the entire United States’ population! The Delaware River watershed provides important ecological habitats to a multitude of species, and provides recreation for cyclists, hikers, paddlers and other outdoor enthusiasts. Help us asses the heath of the river by adding an observation to this project! פחות ↑
