There was no ship channel in the early years. Had to go thru Big Lake and then a snake of a river up to Lake Charles.
Ship channel was cut straight and made a lot more saltwater go farther inland.
There probably was brackish or saltwater intrusion back in the day, but it would have to have a drought to do it.
Same with all that marsh East of the lake. Grand and Lambert Bayous were small and didn't allow a lot of saltwater to go in.
All that marsh off the highway below the Gibbstown was fresh.
