About this map

The Eastern Isles Dernieres barrier islands stretch across the central portion of this coastal survey, serving as a critical boundary between the Gulf of Mexico and the inner estuarine waters of Trinity Bay. This fragile landscape in Terrebonne Parish is defined by a complex network of tidal inlets and navigable channels, including Wine Island Pass and Old Camp Pass.

To the north, the expanse of Terrebonne Bay dominates the horizon, shaped by landforms such as Point Mast and Bodwin Point. Human modification of the shifting hydrology is evident in features like the California Canal and the Bodwin Cutoff, which provide passage through the salt marshes and bayous. The map captures the delicate state of these coastal features, highlighting the narrow strips of land and shallow bays like Bay Blanc and Pass la Poule that characterize this dynamic maritime environment.
