2012 Map of Lake Athanasio

About this map

Saint Helena Bay and the surrounding marshlands of Saint Bernard Parish define this coastal landscape, where land and water merge into an intricate network of inlets and islands. The 2012 survey illustrates the complex geography of the Mississippi River Delta's outer reaches, featuring tidal passages like Mulatto Bayou and the winding Bayou Frenepiquant. Human engineering appears in the form of Canal Pecal, cutting through the wetlands to facilitate movement between larger bodies of water like Lake Machias and Seven Dollar Bay. The map captures numerous landforms subject to the constant influence of the Gulf, from Coon Nest Island to the southern tip at Point Fortuna. This detailed record is essential for understanding the shoreline configuration and maritime landmarks such as the Lake Eloi Light 1 during the early 21st century.
