AMES, Iowa (AP) – More than half the manufacturers surveyed in six western Iowa counties say they are being affected by Missouri River flooding. The flooding has played havoc with transportation logistics and employee commuting, given the blockages of Interstate 29 and the closing of some Nebraska-Iowa bridges over the river.

Iowa State University Extension and Outreach Center for Industrial Research and Service contacted about 200 manufacturers total in Fremont, Harrison, Mills, Monona, Pottawattamie and Woodbury counties. About 120 took part in the survey, and 53 percent of them reported problems. Outreach center program manager Ruth Wilcox says the manufacturers will be experiencing flood-caused problems for many months as they deal with regional issues such as levee conditions and degraded roads.
