MyRWA was founded in 1972 and has largely functioned through the efforts of professional staff and community volunteers working together on a project-by-project basis.


The Mystic River Watershed Association's mission is to protect and restore the Mystic River, its tributaries and watershed lands for the benefit of present and future generations and to celebrate the value, importance and great beauty of these natural resources.
