Are the Great lake states considered lanklocked?

No, they are not land-locked. Neither is Lake Pontchartrain in southern Lousiana. Lake Pontchartrain is NOT fresh water. It's definitely saline. Just taste it, but check on the latest E.coli count before you do. The last time it was safe to swim in the lake on the south shore was in 1956. I was three years old, and that was the only time I was allowed to go into lake water at Pontchartrain Park by my mother. Part of Pontchartrain Park is now a housing development.
