2012 Map of Calumet Island

About this map

The coastal marsh and barrier island geography of Lafourche Parish is defined here by the thin, shifting strand of East Timbalier Island as it meets the Gulf of Mexico. This coastal environment is deeply connected to the region's energy and maritime infrastructure, anchored by the Timbalier Bay Oil Field. The reliance on air and water access is evident through the presence of specialized facilities such as the Timbalier Bay Seaplane Base and the Timbalier Bay Camp Seaplane Base. To the north, detached landforms including Calumet Island and Casse-tete Island show the fragmented nature of the Louisiana shoreline in the early 21st century, where the boundary between open water and solid ground is constantly in flux.
