1983 Map of Atchafalaya Bay

About this map

The expansive Atchafalaya Bay and the adjacent Gulf of Mexico dominate this 1983 topographic-bathymetric study, revealing a complex coastal landscape of shifting reefs and wildlife sanctuaries. Conservation efforts are well-established along the Louisiana coast, marked by the Russell Sage Foundation-Marsh Island State Wildlife Refuge and the Shell Keys National Wildlife Refuge. The map details the intricate waterways and islands of the delta, including Point Au Fer Island and the isolated Mosquito Island. Navigation and maritime activity are evidenced by the presence of a Lighthouse, a designated Dump Site, and the Pelican Battery landmark. The transition from the brackish waters of East Cote Blanche Bay to the open gulf highlights the delicate ecological balance of the Atchafalaya Delta State Wildlife Management Area, where the interplay of silt and sea continues to reshape the coastline.
