Dauphin Island is a fishing village and summer resort at the NE part of Dauphin Island. A dredged channel leads from Mississippi Sound through Bayou Aloe to an anchorage basin at Dauphin Island Village. In 2011, the midchannel controlling depth in the entrance channel was 7 feet with 1.5 to 5.5 feet in the basin. The channel is marked with lights and daybeacons.
From Mobile Bay, the waterway goes through Pass aux Herons to the open water of Mississippi Sound. Dauphin Island Bridge across the waterway at Mile 127.8E has a fixed span with a clearance of 83 feet. An overhead power cable on the W side of the bridge has a clearance of 93 feet over the waterway.
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.
