About this map

China Island and the sprawling waterways of Terrebonne Parish define this coastal landscape, where the land-to-water ratio illustrates a delta in constant flux. The northern reaches are dominated by Moncleuse Bay and the winding course of Bayou Grand Caillou, a primary artery for the region's complex hydraulic network. This 2020 survey reveals a labyrinth of named passes and bayous, such as Pass des Iles and Quitman Bayou, which serve as critical corridors through the marshlands.

Southward, the expanse of Dog Lake opens up, surrounded by smaller features like Petit Pass des Ilettes and Bayou des Ilettes. The intricate naming convention for every small body of water, from Muskrat Bayou to Trouble Bayou, reflects the deep localized knowledge required to navigate these wetlands. The lack of road infrastructure emphasizes a water-based geography where transportation is dictated by the tides and the seasonal flow of the bayous.
