Our Mission
To work as a community for clean and healthy lakes, ponds, and streams in our watershed.
The 30 Mile River Watershed Association is a non-profit, public-private collaboration of seven rural towns, nine lake associations and two land trusts. We help the region’s communities respond to threats from development and invasive species with a comprehensive and more organized approach.
