(Radio Iowa) – The Mississippi River is slowly returning to its banks, leaving behind a muddy mess. Last week, the river swelled to major flood stage in the Quad Cities, following heavy rains in the Upper Midwest. Davenport city workers put up temporary barriers and used pumps. Assistant City Administrator and Public Works Director Nicole Gleason says the efforts were successful, but the HESCO barriers will remain in place until the river descends below 18 feet. “It’s all just going to be dependent on the rainfall,” Gleason says. “We can’t really guess that far out. Right now, it looks like we’re getting close back to that 18-foot level about a week from now. So I would probably think by midweek next week we should have a plan together for when we start dismantling mitigation measures.”

Gleason says the flooding came at an unusual time of the year for Davenport.  “More traditionally, we see the flooding more in April as it relates to snow melt, and spring rain on top of snow melt,” she says, “but in this case it was 100% rain-driven.”

Gleason says that “rain-driven” flooding is harder to predict than flooding from snow melt. This flood crested at just above 20 feet in the Quad Cities. The record there is 22-point-7 feet, set in 2019.
