About this map

Bayou Chene marks a point of historical interest in this riverine landscape, where the shifting waters of the St. Martin Parish wetlands meet the managed environment of the Atchafalaya Basin Floodway. The terrain is defined by a dense network of water bodies, from the expansive Lake Mongoulois and Tensas Bay to smaller, curiously named channels like Four Hundred Dollar Bayou and Logan Chute. These waterways isolate various landmasses such as Slim Island and Cozine Island, creating a complex swamp ecosystem that has historically dictated patterns of movement and settlement.

The hydrological structure is further shaped by engineered cuts and natural bayous, including Blind Tensas Cut and the Upper Grand River. This environment suggests a landscape where water levels and drainage are central to local geography, influencing the location of features like Cow Bayou Cove and Jack Island. The presence of the parish boundary between Iberville Parish and St. Martin Parish underscores the administrative divisions running through these remote wetlands.
