About

The Neponset River Watershed Association is a grassroots, member-supported conservation group working since 1967 to clean up and protect the Neponset River, its tributaries and surrounding watershed lands.

The River has come a long way from its days as a severely polluted industrial river. Today, most streams in the Neponset River system meet swimmable standards during dry weather, and much of the river has been opened up for canoeing, bike paths and waterfront parks.


Our Mission Statement

To protect the water, wildlife and land of the Neponset River and Watershed.


Our goal is a clean, healthy, accessible river and watershed, from the smallest headwater stream to the wide-open brackish water of the estuary.
