Flash Flooding Leads to Emergency Evacuations in Clayton County, Road Closures

Flash flooding prompted emergency evacuations in Clayton County last night.

Five to eight inches of rain fell late Tuesday night into the overnight hours as storms continuously moved across the area. The heavy rain caused the Little Turkey River and Mill Creek to overflow.

The Clayton County Sheriff’s Office estimates it evacuated 15 to 20 homes overnight as the waters rose. Some of the evacuations included a mudslide at a home along Osterdock Road and along Graham Street in Millville. Authorities say the southeast corner of the county was the hardest hit.

Several roads have also been damaged across Clayton County from the heavy rainfall, though a deputy with the Sheriff’s Office says Highway 52 in Clayton County remains open. The bridge on Millville Road off Osterdock Road is reportedly closed.

However, a portion of Highway 52 in Dubuque County is closed after up to five inches of rain fell in northern Dubuque County in a two to three hour period last night. The Dubuque County Sheriff’s Office says Highway 52 North is flooding in the area of Rupp Hollow Rd, as well as having issues with trees and a power pole down between Sageville and Durango. If you need to travel through these areas, please find an alternate route. Clay Hill Road is also blocked by downed trees.

Thunderstorms packing winds up to 75 mph also downed trees and power lines in Dubuque County overnight, leaving thousands of people without electricity.

Golf-ball sized hail was also reported in the Osterdock area after Wednesday morning’s storms moved through.

A Flood Warning continues for Clayton County until 1:15 pm today, and a Flash Flood Watch is in effect for Dubuque County until 7 pm tonight.
