2020 Map of Lake Theriot

About this map

Theriot sits at the edge of a complex watery landscape where human engineering meets the tidal marshes of Terrebonne Parish. The settlement is anchored by Saint Eloi Cem and connected to the broader region via Bayou DuLarge Rd. The map illustrates the sophisticated network of waterways essential to coastal life, featuring prominent basins like Lake Theriot and Lake De Cade, alongside man-made passages such as Minors Canal and Marmande Canal. Higher ground is found along Marmande Ridge and at Bruly Mauvais Bois, providing critical firmament in a region dominated by wetlands and islands like Congo Island. The intricate drainage patterns, including the Falgout Canal Bayou and Fohs Canal, reveal the ongoing efforts to manage water flow and navigation in this low-lying deltaic environment, offering a detailed record of the parish's coastal geography.
