About this map

Bayou Saint Malo and the surrounding marshlands of Saint Bernard Parish define this coastal landscape on the edge of Lake Borgne. The area is characterized by an intricate network of tidal waterways, including Bayou la Loutre and Bayou Muscelini, which trace through the low-lying wetlands. Notable landforms rise slightly above the water, such as Pointe aux Marchettes and Magnolia Mound, serving as essential reference points in a region dominated by fluctuating shorelines and lagoons.

The presence of named water bodies like Petes Lagoon, Brick Lagoon, and Magill Lagoon suggests a landscape shaped by local maritime use and subsistence. This detailed survey preserves the precise alignment of the region's bayous and lagoons before further coastal change, offering a clear record of the territory between Bayou Magnolia and the expansive Lake Borgne as it appeared in the early twenty-first century.
