About this map

Industrial activity and maritime geography dominate this coastal landscape, where the Lake Barre Oil and Gas Field and the Caillou Island Oil and Gas Field define the human footprint. Situated at the interface of Terrebonne Parish and Lafourche Parish, the map shows an intricate network of platforms, tanks, and oil wells scattered across the water. The coastal morphology includes expansive water bodies like Lake Barre, Lake Raccourci, and Timbalier Bay.

A notable geological detail is the Formation, a series of islands and marshes that separate Jacko Bay from surrounding waters. The transition from Terrebonne Bay to the open gulf is marked by shifting features like the shoal near Terrebonne Island. This 1994 revision reflects the mid-century industrial development of the Louisiana coast as it stood before significant late-20th-century coastal changes.
