About this map

Bayou du Large meanders through the marshy landscape of Terrebonne Parish, anchoring the small settlement of Theriot and its local Po. This 2015 survey illustrates the complex water management systems of south Louisiana, where artificial waterways like Minors Canal, Marmande Canal, and the Falgout Canal cut through the wetlands to facilitate drainage and transport. These canals interface with natural features such as Lake Theriot and the large expanse of Lake De Cade to the southwest.

Elevated terrain is represented by Marmande Ridge and Congo Island, which stand out against the surrounding Bayou Mauvais Bois. The map provides a contemporary view of the local infrastructure, including named thoroughfares like Dr Beatrous Rd and Falgout Rd, which follow the natural levees of the bayous. This documentation of the shifting coastal environment is essential for understanding the modern footprint of these historic Louisiana waterways.
