Came together in 1996 to address the troubling problems of pollution in our beloved Cotuit, North, and West Bays, as well as the rapid erosion of the barrier beaches of Dead Neck/ Sampson’s Island. In the nine years since, more than 1,000 of our friends and neighbors have joined us in our efforts, and Three Bays Preservation has grown into a major organization of dedicated people who donate their time and resources for the preservation of our aquatic environment.
