Dauphin Island Bay is a shallow bay at the E end of Dauphin Island between Dauphin Island Bridge and Little Dauphin Island. The bay is accessible from Mississippi Sound through a privately marked and dredged channel and from Mobile Bay through an inlet protected by a jetty about 0.2 mile N of Pelican Point. A channel marked by lights and daybeacons leads from Mobile Bay to the inlet entrance, thence a dredged channel leads through the inlet to an anchorage basin at Fort Gaines, thence a connecting channel leads from the anchorage basin to Dauphin Island Bay. In 2011, the controlling depth was 3.5 feet in the entrance channel to the basin, thence 6 feet in the basin, thence 3 feet at midchannel in the connecting channel.
Dauphin Island Coast Guard Station is on the S side of the inlet.
