1964 Map of Lake Theriot

About this map

Bayou du Large serves as the primary corridor for human activity in this 1964 survey of the Terrebonne Parish wetlands. The settlement of Theriot and the Lower Bayou du Large Sch are situated along the narrow, habitable natural levee of the bayou, contrasted against the expansive surrounding marsh. The landscape is defined by its transition from natural hydrology to industrial management, featuring large water bodies like Lake Theriot and Lake de Cade alongside an increasingly complex network of artificial channels, including the Falgout Canal and the Thibodaux Canal. Local industry is prominent through the Lake Hatch Oil and Gas Field and the South Sunrise Oil and Gas Field. Higher ground is rare, found only at features such as Marmande Ridge, Congo Island, and a documented Indian Mound.
