2024 Map of Bay Dosgris

About this map

The boundary between Jefferson Parish and Lafourche Parish snakes through a complex wetland landscape dominated by winding waterways and expansive coastal bays. This 2024 survey captures the intricate hydrology of the region, where the Grand Bayou and the Barataria Bay Waterway serve as critical arteries through the marsh. Cultural markers are few in this salt-marsh environment, but the Alombro Cem stands as a significant genealogical landmark for those tracing coastal family histories. The map details a network of named inlets and passages including Coffee Bay, Manila Bayou, and Snail Bay, which together illustrate the shifting shoreline and the tidal influence on the lower delta. From the East Fork Bayou L'Ours to the secluded Creole Pass, the topography reveals a terrain almost entirely defined by water and the delicate transition between land and the Gulf influence.
