About this map

The Mississippi River corridor in St. John the Baptist Parish dominates this 1967 survey, capturing the industrial and hydrological engineering required to manage the southern Louisiana landscape. The massive Bonnet Carre Floodway and Bonnet Carre Spillway stretch from the river to Lake Pontchartrain, providing a stark visual of the region's flood control infrastructure. Nearby, the site of the Hymelia Crevasse (1912) serves as a historical marker of the river's power.

Energy production is a central theme, evidenced by the Laplace Oil and Gas Field and a large refinery near Norco. Residential growth is visible in emerging neighborhoods like Carrollwood and Riverland Heights, while older riverside communities such as Montz, Gypsy, and Lucy maintain their traditional riverfront orientations. Along the lake shore, the settlement of Frenier and Frenier Beach sit adjacent to the Old Hammond Road, marking the transition into the wetlands and bayous like Bayou Trepagnier.
