Lake Pontchartrain dominates the southeastern portion of this coastal Louisiana landscape, where a complex network of waterways defines the geography of Tangipahoa Parish. The central navigational artery, Pass Manchac, serves as the primary connection between the open lake and interior basins, marked by the historic Pass Manchac Lighthouse standing watch near the shoreline. The drainage pattern is characterized by numerous slow-moving channels, including North Pass and the meandering Tangipahoa River, which carries upland waters toward the coast.
