About this map

The coastal marshlands of St. Bernard Parish are defined here by a dense network of waterways and the significant engineering of the Mississippi River - Gulf Outlet Canal. This mid-century landscape, largely protected within the Biloxi State Wildlife Management Area, shows the transition from natural coastal features like Lena Lagoon and Lake Jean Louis Robin to man-made industrial adjustments. Extensive spoil areas line the primary canal, reflecting the massive dredging efforts required to maintain this maritime corridor.

Smaller natural channels such as St Malo Bayou and La Loutre Bayou weave through the tidal flats, connecting with bodies like Magnolia Lagoon and Lagoon Giraud. For researchers of Louisiana's changing coastline, the placement of numerous drill holes and navigation aids like lights indicates the historical footprint of oil exploration and commercial shipping in the late 1960s, prior to significant later coastal erosion and land loss in the region.
