About this map

The marshlands and interlocking waterways of the Jefferson Parish and Lafourche Parish line define this coastal landscape as it was surveyed in the mid-1930s. The territory is dominated by expansive water bodies like Little Lake and Bay Dosgris, connected by a complex system of natural channels including Grand Bayou and Old Grand Bayou. This survey serves as a vital record of the Louisiana coastline before significant 20th-century coastal erosion and canal dredging altered the hydrology of the region.

Local history is anchored by the presence of the Alombro Cem, situated near the banks of East Fork Bayou L'ours. The map details the intricate shoreline of numerous smaller bays, such as St Joseph Bay, Snail Bay, and Liveoak Bay, which provided essential navigation and fishing grounds for the surrounding communities. Other notable waterways include Bayou St Denis and Cassetete Bayou, reflecting the intricate drainage patterns of the Mississippi River Delta's wetlands.
