Southwest Pass defines the hydrological character of this coastal landscape within Plaquemines Parish, where the Mississippi River delta meets the open Gulf of Mexico. The area is dominated by an intricate network of wetlands and shallow water bodies, including West Bay and Mud Bay, which reflect the dynamic nature of southern Louisiana's shoreline. The presence of Burrwood Bayou and Stake Island Bayou highlights the complex distributary system of the delta in the early 21st century. This survey documents the specific configuration of land and water in a region where environmental shifts constantly reshape the coastal margin.
