About this map

Bourg and the surrounding marshlands of Terrebonne Parish are defined by an intricate network of natural bayous and engineered channels. The modern Intracoastal Waterway cuts a straight line through the landscape, intersecting the winding course of Bayou Blue near the Bayou Blue Bridge. This intersection highlights the evolution of Louisiana’s coastal infrastructure, where traditional waterborne paths meet mid-century commercial arteries.

Genealogists and local historians will find several burial sites including Bisland Cem, Matherne Cem, and Saint Ann Cem, providing a record of established family names in settlements like Klondyke and Grandbois. The terrain is dominated by water features such as Lake Long and Bayou Terrebonne, while the local road network, including Little Caillou Rd and Montegut Rd, follows the higher ground created by the natural levees of the various bayous.
