Neponset River

The Neponset River is a river in eastern Massachusetts in the United States. The headwaters of the Neponset are at the Neponset Reservoir in Foxborough, near the Gillette Stadium. From there, the Neponset meanders generally northeast for approximately 29 miles (47 km) to its mouth at Dorchester Bay between Quincy and the Dorchester section of Boston, near the painted gas tank.

Neponset River and its watershed are increasingly being protected and opened up as a recreational destination for the benefit of local residents. Several recommendations of the 1966 Lower Neponset River Reservation Master Plan have been implemented, including the reclamation of the former Hallet Street landfill and the old Neponset Drive-In to provide the 66-acre (270,000 m2) Pope John Paul II Park, which opened to the public in 2001.
