Winter Harbor, in the town of Winter Harbor, is a small, protected harbor on the west side of Schoodic Peninsula in Blue Hill Bay, about six miles east of Bar Harbor. Winter Harbor consists of a large outer harbor, which is enclosed on the west by Grindstone Neck, and three smaller coves along its northern side - Henry Cove, Inner Harbor, and Sand Cove. Inner Harbor, which is situated between Guptill and Harbor points, is used principally by commercial fishing boats.

In 1975, the Corps completed construction of an eight-footdeep anchorage, 75 feet wide and 6.5 acres in area, extending about 1,200 feet from the entrance of Inner Harbor to the Fisherman’s Cooperative Wharf. The work was constructed under Section 107 of the Continuing Authorities Program.
