Three Bays, the non-profit established to improve the water quality in the Cotuit-Marstons Mills-Osterville area has an interesting history of the barrier island at the face of the three bays: Dead Neck/Sampson’s Island. I had seen some interesting development plans for the island dating back to the 1920s that showed an air strip, a polo field, and a bridge over to Oyster Harbors across the Seapuit River. But this article provides some fascinating details about how this important migratory bird nesting area was turned into an island by the people of Osterville (with somewhat negative coastal consequences 100 years later) and then saved from development by local philanthropists.
An interesting fact: my favorite spot on the Cape, a small cove that was once the primary point of entrance and egress for Cotuit Bay into Nantucket Sound is called “Cupid’s Cove” by people in Cotuit and “Pirate’s Cove” by people in Osterville. Here’s what the article says about the impact of the Wianno Cut on the beach, something I’ve suspected for a long time.
“Again in the late 1980’s, he began another round of sand replenishment. It appeared that the jetty that had been built to create a gateway to Nantucket Sound was causing the island to lose much of its sand every winter.”
