2024 Map of Bay L'Ours

About this map

The low-lying wetlands of southern Louisiana define the geography of the Bay L'Ours region, where the aquatic landscape is shaped by a intricate network of bayous and tidal bays. This 2024 survey documents the meandering course of Bayou Perot and the expanse of Bayou Rigolettes as they define the boundary between Lafourche Parish and Jefferson Parish. The area is characterized by vast reaches of marshland, with open water features like Turtle Bay and Bayou de la Gauche providing the primary structure to a landscape largely devoid of terrestrial roads or settlements. The presence of the Harvey Cutoff indicates the ongoing importance of managed water channels in this fragile deltaic environment, serving as a vital link for local navigation and coastal water management at the current date.
