Pepperell Cove in Kittery is located at the mouth of the Piscataqua River, which forms a portion of the Maine-New Hampshire boundary. The cove services lobster and fishing fleets and a large recreational fleet. Several lobster firms are located along Chauncey Creek at the head of the cove.

The project, on the northwest side of Pepperell Cove, is a 12-foot-deep anchorage, 12.5 feet over rock, approximately 1,450 feet long and 1,250 feet wide. Work was completed in 1916.
