To cultivate the resilience of our coastal pond ecosystems through science, collaboration, and education.
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.
Everyone is enjoying this warm spring day☀️! Our team started their morning on Edgartown Great Pond with some logger 📊maintenance. They were happy to be greeted by a lion’s mane 🪼 , mostly likely brought in by the recent cut!!

The cut ✂️of #EdgartownGreatPond remains open and tidal 🌊 as of 3:30 pm 🕝 Thursday, March 26th. The tidal range of the Pond is ~1 foot, which is very good and last happened in July 2024.. The volume of water exchanged during a cut is a combination of the number of tidal cycles the tidal range during those cycles 🔄. Ideal cuts maximize flushing and increase salinity 🧂pond-wide about 8-12 ppt (parts per thousand) and stay tidal for at least 9-11 days. 🙏Thanks to Rob Morrison and the Town of Edgartown for getting the Pond drained and flushing before the warm season. Spring 🌱cuts tend to set the tone for the health of the Pond throughout the summer and fall 🦪🌱🌱🦦. Photo credit @sully7777777777 👌
