1968 Map of False Mouth Bayou

About this map

Lake Borgne dominates this coastal survey, where the brackish waters of the estuary meet the intricate marshlands of St. Bernard Parish. The landscape is a complex network of tidal waterways and lagoons, primarily preserved within the Biloxi State Wildlife Management Area. This 1968 study, updated with 1976 revisions, reveals a wilderness shaped by water, where False Mouth Bayou and Magill Bayou serve as primary conduits for the tides. The map detail highlights the fragmented shoreline of the Lakes of Bayou Marron and the opening of Mosquito Inlet, illustrating a delicate environment where firm land is scarce. For researchers of the Louisiana coast, the data provides a clear record of these wetlands before decades of modern coastal erosion significantly altered the geometry of Magill Lagoon and the surrounding marsh.
