Officials forecasted the river to crest at 17 feet, five feet above flood stage, but it crested at 12.5 feet. Right now, the river is below flood stage at 11 feet. More showers and thunderstorms are in the forecast this week. Floyd County Emergency Management Coordinator Lezlie Weber says regardless of the forecast to have a plan.
