What happened

The episode as NWS LSX wrote it up.

Fed primarily by water from a flooding Missouri River, the Mississippi River from its confluence with the Missouri south to Chester, Il also flooded. On average, the river crested about 6 feet over flood stage at most locations. Many roads along the river were flooded as was farmland on the inside of levees. All levees along the river held and none were overtopped. Parts of the floodgate along the river in St. Louis were closed, primarily as a precaution and to keep people out of the flooded riverfront streets.
