About this map

St. Bernard Parish, Louisiana, reveals a complex coastal landscape defined by the heavy intersection of natural waterways and industrial engineering in the early 1990s. The central feature is the massive Mississippi River-Gulf Outlet Canal, a deep-draft shipping channel that cuts diagonally across the marsh, fundamentally altering the surrounding hydrology. North of this channel, the marsh is fragmented by historically significant bayous such as Bayou La Loutre and Bayou Musclini, which snake through the wetlands toward Lake Borgne.

Man-made interventions like the Engineers Canal and Bakers Canal show the persistent efforts to manage water and transit through these tidal flats. To the south and west, the terrain transitions into a scatter of shallow water bodies, including Lena Lagoon, Lake Coquille, and the family-named Lake Jean Louis Robin, providing a detailed look at the brackish environment before coastal erosion and subsequent storms further reshaped these vulnerable Louisiana wetlands.
