About this map

Lake Borgne dominates the western extent of this coastal landscape, where the tides of the Gulf of Mexico meet the intricate marshlands of Saint Bernard Parish. The coastal geometry is defined by winding waterways such as Bayou Magill, which flows into the sheltered Magill Lagoon near the southern margin. This area represents a critical interface between open water and the fragile wetlands of the Mississippi River Delta, where the land is carved into a complex network of inlets and internal lakes.

Waterways like Mosquito Inlet and False Mouth Bayou provide the primary geographic structure for this largely uninhabited territory. Further east, the Lakes of Bayou Marron punctuate the marshy interior, illustrating the dynamic nature of Louisiana’s shifting coastline. These features highlight the specialized environment of the region, where navigation is dictated by the natural flow of bayous rather than man-made roads.
