The Quad Cities have been preparing since the National Weather Service reported earlier this year a 95 percent chance of pronounced flooding in the area through May. As of Tuesday, their temporary barriers had been in place for 48 days. This week, their preparations proved insufficient.

Tuesday afternoon, Mississippi River floodwaters suddenly rushed into Davenport when HESCO Barriers — military grade defense boxes used to make temporary walls — succumbed to the force of the water. Officials saw early signs, the Quad City Times and Dispatch-Argus reported, and began urging people in some areas to evacuate when the temporary levees began breaking around 3:30 pm. The HESCO barriers had never been tested in waters above 21.5 feet, but as of 4:30 pm the Mississippi was at 21.87 feet, heading quickly to the expected 22.4 foot crest.

Not everyone received or took seriously the evacuation warnings, and many had to be rescued by boat after the fact. Once the water came rushing in, there was little time to take action. No serious injuries were reported.

The Weather Channel reported that floodwater began to recede Wednesday morning, and that at their peak levels surpassed 6 feet in some areas. A new expected crest of 22.7 feet is expected later today, which could surpass the 22.6 foot record set in 1993.

Scott County officials and Gov. Kim Reynolds are hoping President Trump’s earlier disaster declaration for western Iowa will extend into the Quad Cities area, local media reported.
