The Missouri River's fluctuating water levels are keeping crews busy fixing broken sewer lines and filling sinkholes around Council Bluffs.
The Army Corps of Engineers believes the river will fluctuate between 23 feet and 28 feet deep over the next week, The Daily Nonpareil reported .
The water rises as upstream dams release water in order to reduce flood risk along the lower Missouri River, the agency said.
The river's ebb and flow has created several sinkholes in the city, said Dan Christensen, the sewer department supervisor for Council Bluffs Public Works. The issue has been complicated by heavy rain and drainage issues.
"It's a disaster," Christensen said. "We're swamped."
