About this map

Marsh Island dominates this coastal landscape, showcasing an intricate network of wetlands and tidal waters in Iberia Parish. The southern reaches of the island are defined by significant hydrologic features like Oyster Lake and the branching pathways of West Branch Oyster Bayou and East Branch Oyster Bayou. These waterways suggest a dynamic environment where freshwater and saltwater meet, characteristic of Louisiana's fragile gulf coast.

Toward the northern and eastern portions of the island, a cluster of interior lakes including Lake Michael, Lake Blanc, and Scat Lake provide crucial reference points for understanding the island's interior topography. The surrounding bays, notably West Cote Blanche Bay and East Cote Blanche Bay, frame the marshland, while smaller features like Worm Point and Worm Cove reveal the fine-grained detail of the shoreline as it existed in 2020.
