1941 Map of Bayou Du Large

About this map

Marmande Ridge and the settlement of Theriot anchor this coastal landscape in the early 1940s, where habitation is tightly clustered along narrow strips of higher ground. The map reveals the intricate water network of southern Terrebonne Parish, dominated by Lake De Cade and the expansive Caillou Lake to the south. Land use in this era is defined by the proximity to water, with Johnson Ch and St Andrews Ch serving local residents along the bayous. The presence of an Indian Mound near the northern canal systems suggests a deep history of human activity in these wetlands long before modern drainage projects like the Falgout Canal. From the remote Bourgs Camp to the winding course of Bayou Copasaw, this survey documents a period when local life was inextricably tied to the tides and the seasonal flow of the Louisiana bayou.
