2020 Map of Plumb Bayou

About this map

Atchafalaya Bay and Fourleague Bay dominate the southwestern reaches of this coastal survey, where the terrestrial world gives way to the marshlands of southern Louisiana. The landscape is defined by a dense network of winding waterways such as Plumb Bayou, Creole Bayou, and Crooked Bayou, which carve through the wetlands to create isolated landmasses like Rainbow Island and Halters Island. The boundary between Terrebonne Parish and St. Mary Parish runs through these waters, marking a region where traditional land-based settlements are absent in favor of a purely aquatic environment. This map captures the intricate hydrography of the deltaic plain, illustrating how Creole Pass and various distributaries like Little Carencro Bayou and Bayou Sarian manage the flow of water toward the Gulf. It is a portrait of a dynamic environment where the distinction between land and water is constantly shifting.
