Diving the jetties from 1970 to present. Diving with the tides for slack water very good for fish and crab, also if you know where gaper clams are. Jetties are accessible with caution for all levels of divers with caution as to tidal currents from shore of off boat. North side of the South jetty is the best for fish, crab, clams. The water runs from 10 ft to aprox 60 ft visibility, best at high slack. The ocean water is usually clearer than the river.
