2020 Map of Bastian Bay

About this map

Bastian Island and Lanaux Island stand as thin barriers between the interior marshy bays of Plaquemines Parish and the open Gulf of Mexico. This coastal landscape is defined by an intricate network of tidal waterways, including Bayou Huertes, Bayou de Suite, and Bayou Courant, which drain into larger bodies like Bastian Bay and Garden Bay. The map illustrates a highly fragmented shoreline where narrow strips of land are separated by navigable openings such as Bastian Pass, Grand Bayou Pass, and Chaland Pass. This environment reflects the dynamic nature of the Mississippi River Delta region, where landforms are perpetually shaped by water movement and siltation. The scarcity of terrestrial landmarks and the dominance of named water features like Lake Robinson and Pipe Bay highlight the area's isolation and its primary identity as a maritime and wetlands habitat.
