2012 Map of Cat Island Pass

About this map

Wine Island and the open waters of the Gulf of Mexico dominate this coastal survey of Terrebonne Parish. This map documents a fragile coastal environment where the land-water boundary is in constant flux. The tidal influence is evident in the placement of Bayou l'Ourse, a waterway that reflects the intricate drainage patterns of the Louisiana wetlands. For those studying the shifting shorelines of the Gulf Coast, the relative position of these features provides a baseline for understanding coastal erosion and the historical configuration of the barrier islands and marshes that protect the mainland.
