Saving the Neponset Estuary

• Our Work •
Our goal is a clean, healthy, accessible River and Watershed, from the smallest headwater stream to the wide-open brackish water of the estuary.

The Neponset River Watershed is:
- 120 square miles of land
- a 29-mile-long Neponset River – beginning at Gillette Stadium in Foxborough and ending at the rainbow-painted gas tank by Route 93 in Dorchester
- 120,000 residents who get some or all of their drinking water from within the Watershed
- 330,000+ residents who live, work, and play in its 14 communities
The Neponset Watershed includes parts of 14 cities and towns: Boston (Hyde Park, Mattapan, and Dorchester), Canton, Dedham, Dover, Foxborough, Medfield, Milton, Norwood, Quincy, Randolph, Sharon, Stoughton, Walpole, and Westwood.
Explore the Neponset River, estuary, and ponds by canoe or kayak.

NepRWA relies on the generosity of our members to fund many of our programs, including water sampling, habitat restoration, education, environmental justice, and advocacy.
