2024 Map of Thornwell

About this map

Niblett, Thornwell, and Lowry anchor this landscape along the border of Jefferson Davis and Cameron Parishes. The region is defined by an intricate network of water management, including the Niblett Canal, Thornwell Drainage Canal, and Holton and Winn Drainage Canal, which navigate the low-lying terrain north of the Lacassine National Wildlife Refuge. This area reflects the transition from agricultural fields to the coastal marshlands of south Louisiana, where features like Wildcat Ridge and Goose Island break the surrounding wetlands. Aviation history is noted by the presence of Lyon Airport and Goose Island Airport, serving the remote farms and conservation lands. The southern portion of the map is dominated by the Bayou Lacassine and the Mermentau River, providing a look at the natural drainage patterns into Lake Arthur and the expansive Willow Marsh.
