About this map

Bayou Sale and the surrounding marshlands of St. Mary Parish define this coastal landscape at the start of the 1970s. The map illustrates an intricate network of natural waterways and industrial alterations, where the Intracoastal Waterway cuts through established bayous such as Portage Bayou and Wild Buck Bayou. The presence of the Oil and Gas Field Bayou Carlin and numerous Drill Holes highlights the region's reliance on mineral extraction, while the Pumping Station near Ellerslie speaks to the ongoing efforts to manage water levels in this low-lying delta environment.

Small settlements like South Bend are concentrated along the slightly higher ground bordering the waterways, connected by routes such as Thorguson Road. Extensive dredging for the Williams Storage Canal and various Pipeline Canals reveals how the wetlands were systematically accessed for transport and energy. From the open waters of West Cote Blanche Bay to the inland Fresh Water Lake, the map provides a look at a working landscape shaped by the intersection of traditional navigation and modern industrial expansion.
