Watershed Association

Healthy waters and world-class parks depend on you!

donate today

You can mail in your tax-deductible donation to 20 Academy St., Suite 306, Arlington, MA 02476 or give directly online today. Don't forget to check if your employer has a matching gift program as a way to double or even triple your impact. Even give from your donor-advised fund (DAF)!


Involve your business in a fun, team-building day on the Mystic! We partner with corporations to remove invasive species both on land and on the water during the spring, summer and fall.


Other Ways to Give

Put the Mystic River watershed in your will to keep it healthy for future generations or make a stock gift. Please contact Shelly Liebetreu, Development Director, at (781)-316-3438 for further information.

Attend an Event

Be sure to check out our full calendar for a list of all events. The Herring Run & Paddle is our largest event of the year - held each May in Somerville - and includes a 5K road race and three paddling races! The summer is full of invasive plant removal events with volunteers working from both land and water. We host public meetings throughout the year to share news about our Greenways projects. Learn more about us at our monthly committee meetings or at the Annual Meeting- we encourage newcomers!


Join thousands of other community members working to improve the local environment! We offer a variety of volunteer opportunities – join our team of volunteers by participating in a one-time event or by making a more regular commitment.
