2018 Map of Dixon Bay

About this map

Southwest Pass dominates this coastal landscape, serving as a critical deep-water channel through the Mississippi River Delta toward the Gulf of Mexico. The survey illustrates the complex transition from marshland to open water, defined by a network of interconnected bays and bayous. Significant water bodies like Bay Macoin, Porpoise Bay, and Dixon Bay are separated by narrow land strips and ephemeral drainage channels. To the east, Grand Isle and the Caminada Pass mark the edge of the barrier island system. The map details the intricate hydrography of the delta's lower reaches, including named outlets like Outlet E-1 and Outlet W-1, which characterize the active sediment distribution and coastal erosion processes inherent to Plaquemines Parish. This maritime environment is further shaped by Joseph Bayou and Double Bayou, which meander through the wetlands toward West Bay.
