1964 Map of Lake Theriot

About this map

Marmande Ridge cuts a narrow green path through the low-lying wetlands of Terrebonne Parish, providing the primary dry ground for settlement in this water-dominated landscape. The community of Theriot sits at a critical junction where the Marmande Canal meets Bayou du Large, a focal point for the region's transport and local life. To the west, the expansive waters of Lake Theriot and Lake de Cade define the terrain, interspersed with evidence of the area's mid-century energy boom, such as the Lake Hatch Oil and Gas Field and various pipelines. A complex network of artificial waterways, including the Falgout Canal and Minors Canal, illustrates the extensive engineering required to navigate and drain these marshes. Cultural landmarks like the Lower Bayou du Large Sch and an ancient Indian Mound point to long-term human adaptation to this deltaic environment.
