2025 Map of Bastian Bay

About this map

The Gulf of America tides meet the intricate wetland systems of Plaquemines Parish in this modern-era study of Louisiana's fragile coast. The landscape is dominated by a complex network of bayous and bays, including the expansive Bastian Bay and Garden Bay. Barrier features like Bastian Island, Lanaux Island, and Shell Island serve as critical buffers between the open gulf and inner waters such as Lake Robinson and Bayou Huertes. Navigation through this marine environment is defined by essential channels like Chaland Pass, Bastian Pass, and Grand Bayou Pass, which connect the interior estuaries to the sea. The map documents the intricate hydrography of the region, from the northern reach of Bayou de Suite and Bayou Courant to the southern exposure of Shell Island Bay and Ferrand Bay, illustrating the contemporary state of these shifting coastal landforms.
