1969 Map of Grand River
USGS Topo · Published 1971About this map
The Atchafalaya Basin Floodway dominates this mid-century landscape, illustrating the complex hydrological management of Iberville Parish and ST Martin Parish. At the heart of the swampy terrain, the East Protection Levee stands as a critical barrier, separating the main spillway from the industrial developments of the Bayou Sorrel Oil and Gas Field. This era of the basin was defined by a massive network of natural bayous and man-made interventions, where old waterways like Bayou Maringouin and Bayou Pigeon intersect with the Superior Canal and various Pipeline Canals. Numerous drill holes and gaging stations scattered across the Upper Grand River reflect a period of intensive resource extraction and water level monitoring. Features such as Graveyard Bayou and Berry Lake highlight the remote and primitive character of the basin before more modern infrastructure fully reshaped the region's topography.
