About Us

Established in 1998, Great Pond Foundation leads in estuary science and restoration, using data generated by our programs for informed pond management. Our team builds strong partnerships with neighbors; fostering learning and expertise; and sharing tools and techniques. The coastal ponds of Martha’s Vineyard are globally rare, ecologically fragile, treasures whose preservation and restoration are fundamental to the Island’s long-term sustainability. The Island depends on clean and healthy coastal waters to feed families and support the local economy. These living waters define both the spirit and the character of our community.

Tonight at **6:30 PM**, the Martha’s Vineyard Commission will decide the fate of the Katama Meadows project.

This decision will have lasting impacts on Edgartown Great Pond, a place that is meaningful to so many of us. It’s a living ecosystem, a classroom, and a community treasure. Protecting the health of the pond today helps ensure future generations can experience and appreciate it, too.

If you’re able, please join the meeting in person or on Zoom. Even showing up to listen makes a difference.

To understand the nuance of the situation please read “Decision Time” a piece by Jeremy Houser link in bio👆
Zoom link to the meeting is also in our bio 👆

Hope to see you tonight 💙
