Wider weather episode

Rain that fell during the month of June across Minnesota and Wisconsin caused rises on the Mississippi River along the Iowa and Illinois border. Additionally, heavy rain that fell locally in July helped to prolong the crest and delay the river falling below flood stage, especially south of the Wapsipinicon, Rock, and Iowa Rivers.
