The narrow land bridge between Lake Maurepas and Lake Pontchartrain dominates this mid-century survey, centered on the small settlement of Ruddock. This area of St. John the Baptist Parish is defined by its complex network of waterways, including Black Bayou and Shell Bank Bayou, which weave through the low-lying wetlands. The infrastructure here is heavily tied to the transit corridor provided by the Illinois Central railroad, which runs parallel to the western shore of Lake Pontchartrain.
