Overview

Extensive flooding occurred late May and into June across eastern Iowa, northwest Illinois, and northeast Missouri.  The last half of May was very wet with 5-8 inches of rain falling over the region.  This combined with saturated soils, brought many rivers above Moderate to Major flood levels.  Many climate sites only saw 3 days of no precipitation from May 16th to May 31st. 

The Wapsipinicon, Iowa, Skunk, Des Moines, Rock, and Green Rivers all recorded a preliminary Top 10 crest on record.  The mainstem Mississippi also crested again in late May / early June, with sites from Le Claire LD 14 on downstream recording a Top 10 crest.

Several significant flood events also occurred in March - Early May 2019 due to snowmelt, heavy rain, and saturated soil.  Summary of these events can be found at:
