1998 Map of Grand Isle
USGS Topo · Published 2002About this map
Grand Isle serves as the terminal landmass for this coastal Louisiana survey, where the barrier island meets the expansive waters of the Gulf of Mexico. The map documents a fragile landscape defined by the intersection of natural waterways and industrial development. To the north, Bayou Rigaud separates the town from the marshy expanse of Bay Des Ilettes, while the Barataria Bay Waterway cuts through the sounds to the northeast. Beyond the shoreline, the map shifts to a maritime focus, charting depths and offshore infrastructure. The seabed is marked by the Block 16 Oil and Gas Field and Block 18 Oil and Gas Field, featuring several scattered Platforms. This data provides a clear look at the proximity between the local island settlement, including its Cem, and the energy resources that anchor the regional economy.
