2015 Map of Three Mile Bay

About this map

The Gulf of Mexico dominates this coastal survey of Saint Bernard Parish, revealing a fragmented landscape of marshland, passes, and tidal bays. This 2015 data reflects the complex hydrology of the Louisiana shoreline, where Three Mile Pass and Three Mile Bay serve as critical conduits between larger bodies like Bay Boudreau and the open gulf. The mapping highlights the transient nature of the region's landforms, featuring low-lying landmarks such as Raccoon Island, Little Raccoon Island, and Mink Island. Intricate waterway networks including Johnson Bayou, Drum Bayou, and Picnic Bayou illustrate the labyrinthine drainage patterns characteristic of the deltaic environment. Notable points like Shell Point and Negro Point provide fixed geographic references for navigators and coastal researchers studying this fluid landscape.
