About this map

Biloxi State Wildlife Management Area dominates this coastal landscape in St. Bernard Parish, illustrating the complex intersection of Louisiana marshland and industrial activity during the late 1960s. The map reveals a dense network of waterways, from the broad reach of Lake Borgne and Pte aux Marchettes to intricate interior channels like Bayou Biloxi and Bayou St Malo. Substantial evidence of the region's energy economy is present via the Bayou Biloxi Gas Field and a scattered Drill Hole, showing how infrastructure was integrated directly into the tidal environment.

Local topographic landmarks such as Magnolia Mound provide rare vertical relief in a terrain otherwise defined by lagoons and bayous, including the descriptively named Brick Lagoon, Stump Lagoon, and Muscle Bay. Water management efforts are visible through Jahnckes Ditch, which cuts through the marsh near Bayou La Loutre. This record documents the state of the marsh before decades of coastal subsidence and erosion further altered the St. Bernard shoreline.
