Mystic River Watershed Association

At nearly 76 square miles, the Mystic River Watershed is home to more than one half million residents in 21 communities, making it the most urban and densely populated watershed in the Commonwealth of Massachusetts. From the headwaters of the Aberjona River in Reading to where the Mystic River flows into Boston Harbor between Charlestown and East Boston, the Mystic River Watershed unites a diverse population and offers a variety of opportunities for recreation, wildlife viewing and sight-seeing.

Mission: The Mystic River Watershed Association (MyRWA), which was incorporated in 1972, has a mission 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
