About this map

Lake Maurepas dominates the western half of this 2020 landscape, where the Tickfaw River empties into the expansive basin. The terrain is characterized by a network of wetlands and waterways, including North Pass, T Bayou, and Owl Bayou, which define the low-lying geography of the Louisiana coast. This survey illustrates the modern transportation corridor where Old US Hwy 51 and the interstate system cut a narrow path through the swamps, connecting the small settlements of Akers, Strader, and Sharkey.

Boundaries for Tangipahoa, Livingston, and St. John the Baptist Parishes converge here, highlighting the complex jurisdictional lines in this aquatic environment. Notable landmarks such as Jones Island and the outpost of Galva provide orientation points within a region largely defined by its relationship to the water and the vital transit routes that bridge the gap between the surrounding parishes.
