2024 Map of Lake La Graisse

About this map

Terrebonne Bay dominates this coastal landscape, illustrating the intricate relationship between the Gulf of Mexico and the fading marshlands of south Louisiana. This modern survey reveals a highly fragmented shoreline where open water and narrow tidal passes like Seabreeze Pass and Pass Barre define the geography. The absence of traditional landmarks or roads highlights a region defined entirely by its hydrography and the shifting boundaries of the coastal zone. Bay Chaland and Bay Lost Reef sit within a complex of small islands and bayous, such as Bayou Jose, that characterize the fragile environment south of the mainland. A singular landform, Point Meshe, extends into the bay, providing a fixed reference point in an area otherwise subject to the constant movement of tides and sediment.
