About this map

Plaquemines Parish and the terminating reaches of the Mississippi River are charted in this 1983 topographic-bathymetric survey, capturing the fragile transition where Louisiana's wetlands meet the Gulf of Mexico. The map details the ribbon of settlements that follow the river's course, including Port Sulphur, Buras, and Triumph, terminating at the river-pilot community of Pilottown. The landscape is dominated by complex hydrology, from the broad expanse of Lake Grande Ecaille to the network of channels including Southwest Pass and Main Pass. Large-scale conservation efforts are evident through the Delta National Wildlife Refuge and the Pass a Loutre State Waterfowl Management Area. This mapping period illustrates the intense industrial and navigational importance of the delta, noting numerous Spoil Areas and offshore mineral lease blocks like the West Delta Area.
