About this map

Tangipahoa River and its intricate network of bayous dominate this coastal landscape where the river meets Lake Pontchartrain. The region is defined by a dense labyrinth of natural and man-made waterways, including the Mire Canal, Schleiders Ditch, and First Canal, illustrating a history of drainage and water management in the low-lying wetlands. The boundary between Tangipahoa Parish and St. John the Baptist Parish follows the course of Pass Manchac, a critical navigable channel separating Jones Island from the mainland. This map details the transition from the river's winding tributaries, such as Bedico Creek and Stinking Bayou, into the open waters of the lake, capturing the hydrologic character of the Louisiana coast in the early twenty-first century.
