About this map

Bayou Terre Aux Boeufs snakes through this coastal landscape, defining the boundary between St. Bernard Parish and Plaquemines Parish in southeastern Louisiana. This aquatic environment is a complex network of named lagoons, passes, and bays that reflect the unique hydrography of the Mississippi River delta. Large open waters like Black Bay and Lake Machias are separated by intricate marshlands and named landforms such as Grand Coquille Point and Snake Island.

Smaller water bodies and islands carry distinct local names, including Lake Jean Louis Robin, Grise Bourbe Island, and Gallega Island. The naming conventions here, from Pumpkin Bay to Dead Duck Pass, speak to the region's hunting, fishing, and trapping history. This survey provides a precise view of the shoreline and marsh configuration before further coastal changes, documenting the exact placement of features like Bottle Lagoon and Bayou Numa in the late 2010s.
