2020 Map of False Mouth Bayou

About this map

The coastal wetlands of Saint Bernard Parish are defined by the expansive waters of Lake Borgne and a intricate network of tidal channels. In the southeastern corner of the quadrangle, False Mouth Bayou and Mosquito Inlet illustrate the fluid boundary between the marsh and the open gulf. This landscape is characterized by its isolation and the dominance of hydrographic features such as the Lakes of Bayou Marron and the winding course of Bayou Magill. The lack of terrestrial infrastructure or settlements on this 2020 survey highlights the preserved, aquatic nature of this coastal region. The map provides a precise record of the shoreline and water bodies as they existed before further coastal erosion or environmental shifts, documenting the specific configuration of the Louisiana marshland.
