1969 Map of Grand River

About this map

The Atchafalaya Floodway dominates this landscape, defined by a complex labyrinth of waterways and industrial infrastructure in southern Louisiana. The East Protection Levee provides a sharp boundary between the swamp and the developed margins of the basin, where Gaging Stations monitor the flow of the Upper Grand River. To the east, the Bayou Sorrel Oil and Gas Field indicates the era’s intensive resource extraction, networked by numerous pipelines and canals like the Superior Canal. A dense weave of bayous, including Maringouin Bayou, Pigeon Bayou, and Big Bayou Sorrel, segments the terrain into flats and bays. This 1960s-era survey captures the transition of the Atchafalaya into a managed hydraulic environment, where traditional water bodies like Berry Lake and Sawyers Cove sit adjacent to modern drilling operations and industrial canals.
