2024 Map of Manchac

About this map

Lake Maurepas dominates the lower half of this landscape, where the waters of the Tickfaw River and Natalbany River flow into the massive basin of the Maurepas swamp. This environment is defined by the narrow corridors of dry ground and the waterways that historically connected the interior parishes to the Gulf. The settlement of Akers sits prominently at the bottleneck of Pass Manchac, a vital channel linking the lake to its eastern neighbors. The map details the thin line of transit established along the swamp’s edge, including Old US Hwy 51 and the corridor through Sharkey, Strader, and Galva. This 2024 data reflects a landscape where infrastructure is constrained by the wetlands, centered on the strategic crossing at North Pass and the low-lying terrain of Jones Island.
