1949 Map of Grand Bayou Du Large
USGS Topo · Published 1949About this map
Grand Bayou Du Large and Bayou Grand Caillou snake through the marshy expanse of coastal Terrebonne Parish in this mid-century survey. Compiled from aerial photographs taken by the Air Corps and U.S. Army, the map documents a complex aquatic landscape of brackish bays and tidal channels before modern erosion significantly reshaped the Gulf coastline. The interior is dominated by Caillou Lake and Bay Voisin, while smaller arteries like Fish Bayou and Redfish Bayou provide a detailed view of the hydraulic patterns defining the southern Louisiana wetlands. This document captures the intricate shoreline of Caillou Bay and specific navigational points like Mile Pass and Bay Moncleuse, serving as a foundational record of the region's coastal geomorphology during the post-war era.
