What happened

The episode as NWS DMX wrote it up.

April 2001 began with continued minor to moderate snowmelt flooding in portions of the Iowa, Cedar and Des Moines River basins. The first significant rainfall of the month affected much of the Des Moines Hydrologic Service Area (HSA) on the 5th as scattered showers and the seasons's first thunderstorms moved across the area. Several rivers crossed over from March into April at to just a little over flood stage, but flooding was pretty much limited to agricultural lands.
