The report found that the upper Mississippi River area, comprised of parts of Minnesota, Illinois, Iowa, Wisconsin and Missouri, generates $253 billion annually and supports 755,000 jobs. The total figure was devised by combining the upper river report with a report on the lower river released last year.
