About this map

Marsh Island dominates this coastal landscape in southern Louisiana, defined by a complex network of brackish lakes and meandering waterways. The area is bordered by the expansive West Cote Blanche Bay to the north and East Cote Blanche Bay to the southeast, illustrating the porous boundary between the mainland and the Gulf. Named water bodies like Lake Blanc, Lake Michael, and Scat Lake are scattered across the marsh, connected by tidal arteries such as Bayou Blanc and Joe Aucoin Bayou.

The absence of roads or permanent settlements highlights the environmental character of this region, where the land is primarily shaped by water movement. Distinctive landforms such as Worm Point and Worm Cove break the shoreline, while the branching systems of East Branch Oyster Bayou and West Branch Oyster Bayou suggest the historical importance of these channels for local navigation and resource harvesting in Iberia Parish.
