MIAMI -

On this date in 1993, the Great Mississippi Flood crested at 46.9 feet in St. Louis, MO. This crest easily broke the old record of 43.2 feet set in 1973. While the damage was still an astonishing $20 billion, the 11 mile long, 52 foot high flood wall protected the city center from sustaining even more damage.
