About this map

Lake Tambour and its surrounding network of coastal waterways dominate this part of Terrebonne Parish, revealing a complex landscape of marshland and maritime passages. The map illustrates the hydrological patterns of the Louisiana coast, where larger bodies like Madison Bay and Bay Baptiste transition into narrow, named channels. Cultural features are sparse but significant, notably Madison Canal Rd and the Bush Canal in the northern section, indicating the infrastructure required to navigate and manage this aquatic environment.

Waterways define the topography, from the wide Grand Bayou Bourbeux to smaller branches such as Bayou de la Cache and Bayou Lucien. The Public Land Survey System grid overlays the bayous, marking out townships and ranges that intersect with the natural curves of Bayou Terrebonne. This map is a record of the intricate relationship between land and sea in the delta, where even the smallest Bayou de l' Ouest or Flat Bayou serves as a vital geographic marker.
