A clean, healthy, and Accessible Mystic Watershed begins with you!

The Mystic River is the heart of our 21 communities, connecting 600,000 people to nature, wildlife, and clean water. Right now, that heart is in danger—and it needs you to survive. Please donate today to make a healthy, vibrant, and resilient watershed for all residents. Your donation from now until December 31, 2025—will be doubled up to $13,000 from two generous donors. Don’t wait—make a gift today!

We also accept donations of stock or your Donor Advised Fund. Checks can be mailed to: 23 Maple Street, Arlington, MA 02476
