Olson said that a safety zone was created in order to protect salvage operations from impediment by the vessel traffic above the damaged Marseilles Dam. It extended between the Marseilles Lock and Dam and Seneca, Ill.
"An additional section between Alton, Illinois, and Brendon Road lock at Joliet remained closed for weeks due to high water and excessive river debris," Olson said. "Heavy rains in late May extended the shipping restrictions."
According to Olson, the system of locks and dams on the Illinois River managed by USACE is vulnerable to changing climate and weather extremes. These more frequent and unpredictable conditions can cause shipping accidents, damage to lock and dam systems, streambank erosion, shipping accidents, and local flooding.
"Runaway barges damage Marseilles Lock and Dam during 2013 flood on the Illinois river" was published in the July-August 2014 issue of the Journal of Soil and Water Conservation. Lois Wright Morton co-authored the paper. Olson is a researcher in the Department of Natural Resources and Environmental Sciences in the College of Agricultural, Consumer and Environmental Sciences at the University of Illinois.
