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.ย The coastal ponds of Marthaโ€™s Vineyard are globally rare, ecologically fragile, treasures whose preservation and restoration are fundamental to the Islandโ€™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.

#EdgartownGreatPond is open and draining. The cut looks great and people are coming to check it out. If you have photos and videos this week, please tag @greatpondfoundation or email us at info@greatpondfoundation.org. We will be out monitoring the water quality this week and hope to see the tidal flushes increasing salinity and water ๐Ÿ’งclarity, decreasing nitrogen and cyanobacteria. A cut can shift the ecosystem and return a pond to a healthier balance. Thanks ๐Ÿ™ Rob Morrison and the Town of #Edgartown for this summer cut. #grateful #summer #marthasvineyard #vineyard #summercut #july #beach #ocean #water #tide #AtlanticOcean #southbeach #southshore
