The Lower Atchafalaya River dominates this mid-1960s coastal landscape, defining the watery boundary between St. Mary and Terrebonne Parishes. The region is a dense network of natural bayous and engineered cuts, including the prominent Avoca Island Cutoff and Shaffer Bayou. Industrial development is evident through the numerous drill holes and gas wells that dot the marshlands, particularly within the Bateman Lake Gas and Oil Field and the Deer Island Gas and Oil Field. This survey captures the intricate hydrology of the delta before significant subsidence and coastal changes reshaped the region, showing landmarks like Sword Point and Lake Gascha. Navigational features such as the Gaging Station and various light towers mark the transition from the river to the sprawling marshes of Avoca Island and Deer Island.
