2024 Map of Oyster Bayou

About this map

Point Au Fer Island dominates this coastal landscape where the freshwaters of the Terrebonne marshland meet the Gulf of Mexico. The area is defined by a complex network of tidally influenced waterways, including the winding Little Mosquito Bayou and the more prominent Oyster Bayou to the east. This maritime environment shows the transition between the brackish waters of Bay Castagnier and the open expanse of Fourleague Bay. The map reveals a remote wetland territory characterized by its hydrographic features rather than human settlement, preserving the natural drainage patterns of Vouvia Bayou and the surrounding marsh. This 2024 survey captures the precise intersection of land and sea in a region sensitive to coastal change, providing a detailed record of the islands and inlets as they existed in the early 21st century.
