1946 Map of Oak Mound Bayou

About this map

Oak Mound Bayou anchors this coastal survey of St. Bernard Parish, illustrating the complex wetland geography of the Louisiana shoreline in the mid-1930s. Compiled from Army Air Corps aerial photography, the map reveals a fragile network of marshlands and open water where land is defined by name as much as by solid ground. The central waterway system includes Shell Island Lake and Indian Mound Bay, separated from the Gulf waters by landforms like Mud Grass Island. Navigational routes for local fishermen and coastal mariners are detailed through a series of named openings such as Dutchman Pass, Newton Pass, and S W Pass. The inclusion of Anderson Pt and the winding course of Deadmans Bayou provide specific points of reference for those studying the shifting coastline and historical hydrology of this marshy region before significant modern coastal erosion altered these exact land-and-water boundaries.
