2020 Map of Pass du Bois

About this map

The coastal waters and tidal passes of Plaquemines Parish define this 2020 survey of the Mississippi River Delta's extreme edge. Dominated by the Gulf of Mexico, the area shows the intricate hydrography of the lower delta, where waterways like Pass-Du-Bois and Pass-La-Graisse navigate the shifting marshlands. The map highlights the sparse landmass remaining in the vicinity of West Bay, a region characterized by its precarious position at the terminus of the river system. Included are the Public Land Survey System grids for Township 23 South, Range 30 East, which provide a cadastral framework for this aquatic landscape. This edition serves as a record of the shoreline before further deltaic changes, documenting the precise location of tidal channels and open water boundaries.
