Heavy rainfall across northern Iowa and southern Minnesota sent a wave of flood water south along the Des Moines River The upper reaches flooded earlier in the month with the water reaching farther south after mid month. In addition, another round of heavy rain fell over the central sections of the state. This caused river rises and pushed the Raccoon River and the North River out of its banks. This flood event was all relatively minor.
