Clapboard Creek is located off of the Blount Island Channel, which cuts to the north from the Saint Johns River at Blount Island. Blount Island is a large industrial complex that houses shipping terminals, a U.S. Marine Base and other freight-related operations.
Use NOAA Chart 11491.
Clapboard Creek is best approached from the south via the Blount Island Channel off the Saint Johns River. The opening to Clapboard Creek is crossed by a fixed bridge that limits upstream passage to vessels with less than 19 feet of overhead clearance. A small marina juts out form the northwest shore of the creek.
