Reflections on the Great Flood of 1993

Twenty years ago today we saw record flooding in the St. Louis region:

The Mississippi River at St. Louis crested at 49.6 feet on August 1, nearly 20 feet above flood stage and had a peak flow rate of 1.08 Million cubic feet per second. At this rate, a bowl the size of Busch Stadium would be filled to the brim in 69 seconds. (source

Flooding like this in May 2010 is typical for St. Louis, the 1993 flood was substantially worse, over this track.

Here’s a more detailed look at flooding that year leading up to August 1st:

At St. Louis, the first spring flooding on the Mississippi River was recorded April 8, cresting at .2 feet above flood stage and lasting only that day. The Mississippi rose above flood stage again on April 11 and stayed above flood stage until May 24. The city got a respite as the Mississippi stayed below flood stage May 24 to June 26. On June 27, the Mississippi again went above flood stage and didn’t drop below flood stage for the year until October 7—a total of 146 days above flood stage. The Mississippi River was above the old record flood stage for more than three weeks at St. Louis from mid July to mid August. Prior to 1993, the historic flood of record on the Mississippi River at St. Louis had been 43.2 feet, recorded April 28, 1973. That record was broken July 21, 1993, with a level of 46.9 feet and broken again 11 days later with a record stage of 49.58 feet on Aug. 1. St. Louis is located near the confluence of the Missouri, Illinois and Mississippi rivers, all of which were in flood at the same time. (source

In the  two decades since, Chesterfield’s Monarch Levee was rebuilt and substantial commercial development has happened within the Chesterfield  valley. For example. THF’s Chesterfield Commons:

THF's Chesterfield Commons has over 2 million square feet, this site was flooded 20 years ago.

And now we have two competing outlet malls opening very close to each other on land flooded 20 years ago. In the market for a new Bentley, Maserati, or Aston Martin? Head to STL Motorcars showroom in the floodplain, at 1 Arnage Blvd.  Not even close to St. Louis, but it sounds better than Gumbo Flats Motors on Floodplain Ave.

    And yet they build and re-build on flood plains. And we as taxpayers continue to pay and pay.
