2015 Map of Centerville NE

About this map

The Atchafalaya Basin Floodway dominates this landscape, where the shifting hydrology of southern Louisiana is managed through a complex network of bayous and engineered channels. This 2015 survey reveals how the Intracoastal Waterway and the Gulf Intracoastal Waterway intersect the natural drainage patterns of the basin, facilitating modern maritime transit through the wetlands. The convergence of Iberia, Assumption, and St. Martin parish lines within this watery expanse highlights the administrative complexity of the region. Local water bodies including Bayou Long, Old River, and Bayou Postillion form an intricate labyrinth of channels. These waterways, ranging from the Middle Fork Bayou Long to Little Bayou Mallet, represent the traditional corridors of travel and transport in a region where solid ground is at a premium.
