About this map

Southwest Pass dominates this coastal landscape at the edge of the Mississippi River Delta, serving as a critical navigable artery leading into the Gulf of Mexico. The area is characterized by a complex network of branching waterways and outlets, including Joseph Bayou and Double Bayou, which weave through the shifting wetlands of Plaquemines Parish. On the eastern edge of the pass, the southern tip of Grand Isle appears, marking a transition between the sheltered waters of Caminada Pass and the open gulf.

Water bodies such as Bay Saint Honore, Porpoise Bay, and Dixon Bay highlight the fragmented nature of this low-lying environment. The presence of numerous engineered outlets, labeled from Outlet W-1 to Outlet E-3, illustrates the constant movement of sediment and water management in this fragile deltaic zone. This survey provides a precise record of the shoreline and maritime features, from Cockler Point to the northern reaches of Pass Du Bois.
