Gaillard Island

Gaillard Island is an artificially created island located in Mobile Bay near Mobile, Alabama. It was built by the United States Army Corps of Engineers, using sand and mud dredged from the Mobile Bay ship channel and elsewhere. The island is an important site for colonial nesting seabirds and shore birds in coastal Alabama and has been the only nesting site for brown pelicans in Alabama - first discovered in 1983.

The island is 1,300 acres and is configured in a triangular shape. It is located approximately 3 miles east of Theodore Industrial Park Complex and approximately 11 miles to 12 miles southeast of downtown Mobile, AL. Thirty-one million cubic yards of dredged material pulled from the bay and nearby land was used to form the island. The excavated material consisted primarily of hard red clay from the land and silty sand infused with small amounts of shell and gravel from the bottom of the bay.
