The flood crest of the Big Sioux River was lower than expected, and many areas of Union County dodged significant flooding.
Lieutenant Governor Matt Michels said during the Friday briefing that the crest came earlier than expected………

Michels says a levee break upstream helped take the pressure off the lower river…………

Michels said while the crest was lower, the high water will last longer than originally predicted………

The State D.O.T. along with Union County highway department then quickly removed the temporary flood barriers and reopened Interstate 29.
