Floodwaters breach levees in Midwest

Authorities were using boats and large vehicles on Saturday to rescue and evacuate residents in parts of the Midwest where a recent deluge of rainwater and snowmelt was sent pouring over frozen ground, overwhelming creeks and rivers, and killing at least one person.

Rescue efforts in eastern Nebraska were hampered by reports of levee breaches and washouts of bridges and roads, including part of Nebraska Highway 92, leading in and out of southwest Omaha. Authorities confirmed that a bridge on that highway that crosses the Elkhorn River had been washed out Saturday. In Fremont, west of Omaha, the Dodge County Sheriff ’s Office issued a mandatory evacuation for some residents after floodwaters broke through a levee along the Platte River. And in Mills County, Iowa, authorities ordered people in some rural areas to evacuate after the Missouri River overtopped levees.

The flooding followed days of snow and rain — record-setting, in some places — that swept through the West and Midwest. The deluge pushed some waterways, including the Missouri River, to record levels in Nebraska, South Dakota, Iowa and Minnesota. The flooding was the worst in nearly a decade in places.

The family of farmer James Wilke, 50, of Columbus, Neb., said he was killed Thursday when a bridge collapsed as he was using his tractor to try to reach stranded motorists on Thursday.
