During the day on Sunday, February 27, 2011 Emergency Managers and Law Enforcement from Platte, Polk, and Merrick Counties reported that an ice jam had developed on the Platte River. The location of the ice jam was near the Highway 92 bridge south of Clarks. The ice jam has caused river levels to rise, threatening nearby homes, cabins and roads. On Sunday evening, a dirt dike was built to help protect homes on the south side of the river. The flooding has continued on into Monday, February 28th, and a mile and a half of Prairie Island Road, which is west of Highway 92 and just south of the Platte River in Merrick County, was closed due to rising water levels. As of Monday afternoon the ice jam is approximately 3 miles long, and according to area residents, had grown further west since Sunday evening.

On March 1st, Polk County Emergency Management reported that the river was up, and the ice jam remained unchanged.
