About this map

Marsh Island dominates this coastal landscape where the waters of the Gulf of America meet the labyrinthine wetlands of southern Iberia Parish. The map reveals a complex network of estuarine waterways, most notably the winding course of Bayou Lucien and the long, straight trajectory of Bird Island Bayou as it cuts across the marsh. These natural channels are complemented by the Acadiana Navigation Channel in the northwest, highlighting the area's role in maritime transit and the regional economy.

Strategic coastal points such as Grosse Isle Point and underwater features like Diamond Reef provide critical navigation landmarks for those traversing the edges of Vermilion Bay. Smaller interior bodies of water, including Lucien Lake, Long Lake, and Lake Ferme, illustrate the fragmented nature of the terrain, where land and water are constantly in flux. This survey serves as a precise record of a fragile coastal ecosystem defined by slow-moving bayous and expansive marshlands.
