The Neponset Awaits

Since our founding in 1967, our mission has been to protect and restore the natural resources of the Neponset River, its tributaries, and surrounding watershed lands for the benefit of present and future generations.

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.
