About this map

The Mississippi River-Gulf Outlet Canal carves a massive diagonal through the marshes of St. Bernard Parish, illustrating the significant engineering projects that transformed the Louisiana coastline in the mid-20th century. This 2015 survey reveals a complex coastal landscape where natural bayous like Bayou la Loutre and Bayou Pisana intersect with artificial waterways such as Engineers Canal and Jahnckes Ditch.

The presence of the Hopedale Hwy on the western edge marks one of the few points of land-based access to this water-dominated environment. For researchers and local historians, the map documents the intricate balance between coastal lagoons, including Lena Lagoon and Magnolia Lagoon, and the larger bodies of Lake Borgne and the Gulf of Mexico. It provides a clear record of the area's hydrography following years of coastal erosion and navigation improvements.
