Iowa City Prepares for Floods
IOWA CITY, IA (CBS2/FOX28) -- Officials in Johnson County are preparing for floods once again as water levels in the Iowa River are beginning to rise.
The U.S. Army Corps of Engineers is opening the Coralville Dam to allow 10,000 cubic feet per second (CFS) to flow through the dam, causing low lying areas downstream to flood.
The Corps is balancing the amount of water that the Coralville Reservoir can hold before cresting the spillway, and the amount of water that areas downstream can handle. When the dam opens to 11,500 CFS, Dubuque Street begins to flood.
With that in mind, the University of Iowa is building a 12 foot tall Hesco barrier around the entire perimeter of Mayflower Residence Hall.
The situation echoes the flooding of 2013, and county officials said, they've learned plenty of lessons they are applying to this situation. Still, officials say, people downstream from the dam need to start preparing for flooding.
