1983 Map of Black Bay

About this map

The Mississippi River defines the western edge of this 1983 topographic-bathymetric survey, where riverbank settlements like Chalmette, Violet, and Poydras transition into the expansive marshes of the Mississippi Delta. The landscape is a complex network of bayous and lagoons, including Black Bay, Eloi Bay, and Lake Coquille, reflecting the delicate balance between land and water. The arrival of the Mississippi River-Gulf Outlet Canal creates a sharp linear division through the wetlands, illustrating late 20th-century maritime engineering efforts to bypass the traditional river route.
