1994 Map of Lake Athanasio

A prominent levee protects sensitive terrain as the landscape dissolves into a series of interconnected water bodies such as Lake Machias and St Helena Bay. The presence of landmarks like Gardner Island and Fiddler Point illustrates the fragile coastline before decades of coastal erosion further altered these reaches. Along the southern edge, the map records the boundary between St Bernard Parish and Plaquemines Parish near Black Bay, where the tidal Pass Fernandez connects the inner lakes to the open sound.
