There are two entrances to the harbor. The eastern one, from Merriconeag Sound, is marked by buoys and a daybeacon. It has a depth of about 14 feet, but is narrow and crooked with strong tidal currents. It is suitable only for small craft with local knowledge.
Pinkham Island, on the west side of Merriconeag Sound northward of the thorofare leading westward into Potts Harbor, has one house and is 31 feet high, bare, and grassy. Ledges, bare and covered, extend 500 yards southward of the island to a buoy. A channel northwestward of the island has a depth of at least 8 feet. It leads between shoals and should not be used by strangers.
The western entrance, between Upper Flag Island and Horse Island, is straight and about 225 yards wide at its narrowest part, between Horse Island and the edge of the shoal between Upper Flag Island and Thrumcap, a grass-covered rock. Upper Flag Island, 59 feet high, Little Birch Island, 14 feet high, and Horse Island, 23 feet high, are grass covered.
A ledge extending southwestward from Little Birch Island is marked by a bell buoy, and a shoal covered 3 feet, about 0.2 mile west of Upper Flag Island, is marked on its southwestern end by a buoy.
