The Mississippi River bends sharply at Twentysix Mile Point, defining the industrial and residential corridors of St. Charles Parish. This 2015 layout shows the organized settlement patterns of Hahnville and Destrehan along the riverbanks, contrasted with the extensive engineered drainage network of the Vial Canal, Hymel Canal, and Eighty Arpent Canal to the south. The western edge is dominated by the Bonnet Carre Floodway, a massive civil engineering feature designed to manage river overflow.
