About this map

The eastern expanse of Lake Maurepas dominates this coastal landscape, where the waters of the Tickfaw River and Natalbany River converge in the northwest corner. This area serves as a critical hydrologic junction where the lake drains eastward toward the larger Pontchartrain basin via Pass Manchac and North Pass. The narrow land bridge between the lakes is defined by Jones Island and a thin corridor of infrastructure, including I-55 N and Old US 51, which connect the small communities of Manchac and Akers.

Linear settlements like Strader, Sharkey, and Galva are situated along these primary transit lines, illustrating the historical reliance on narrow natural ridges for transport through the surrounding wetlands. Waterways such as Owl Bayou and the Cecile Canal further segment the marshy terrain, marking a region defined by the meeting of three parishes—Livingston, Tangipahoa, and St. John the Baptist.
