A view of Upper Delaware Scenic and Recreational River
Canoe through rapids and quiet pools as the Delaware River winds its way through a valley of swiftly changing scenery or fish amid rolling hills and riverfront villages in one of the finest fishing rivers in the northeastern United States. The clean water of the Delaware, the last major undammed river in the eastern United States, supports a healthy ecosystem and offers tranquility and excitement.
The National Park Service invites the public to participate in the Dragonfly Mercury Project, a nationwide citizen science initiative focused on monitoring mercury in aquatic ecosystems. Upper Delaware Scenic and Recreational River is seeking 5–6 volunteers to assist with dragonfly larvae collection for mercury analysis on Aug. 4 and 5, 2026 from 10 a.m. to 2 p.m.
