2018 Map of Lena Lagoon

About this map

The intricate wetlands of Saint Bernard Parish are defined by the Mississippi River-Gulf Outlet Canal, which cuts a straight path through the sprawling marsh and bayou systems. This coastal landscape is dominated by a complex network of waterways, where larger bodies like Lena Lagoon and Bernard Lagoon are connected by narrow channels such as Bayou la Loutre and Bayou Saint-Malo. The pattern of development is entirely water-based, seen in the industrial precision of the Engineers Canal and Jahnckes Ditch contrasted against the natural meanders of Bayou Pisana. In the northeast corner, the map borders Lake Borgne, while the interior features numerous lagoons like Magnolia Lagoon and Lagoon Giraud. This survey provides a precise look at the hydrology of southeastern Louisiana before significant further coastal erosion or restoration efforts might alter the fragile interface between the land and the Gulf.
