Can anyone tell me what riverboats are closed on the Mississippi in Iowa and Missouri. I have heard the President in St. Louis and Catfish Bend are closed due to the flooding. Also heard that the Mississippi II is closing June 22nd. We are thinking of taking a long weekend trip to St. Louis and up the Mississippi to Davenport, Ia. but don't want to if a majority of the riverboats are closed. Thanks for any help.
