Also, in a strange turn of events, the University of Iowa has told the city that the coffer dam that UI has constructed near the Iowa Memorial Union is actually pushing flood waters higher than they would normally be.
Because of the coffer dam, flood levels on the river from the IMU all the way to where Clear Creek meets the Iowa River just south of the Iowa River Power Co. restaurant will be at 100-year levels when the outflows reach 25,000 cfs instead of the expected 29,000 cfs it would normally take.
"This means that if flows in Iowa City exceed 25,000 cfs, the flood levels up stream from Iowa Avenue will be higher than experienced in 1993," the statement reads, "and may extend beyond the 100-year flood boundary that is mapped in the Iowa City Flood Insurance Study.
I'll take some pictures of the flooding over lunch hour. Water is projected to come over the spillway at the Coralville resevoir for only the second time in history. The first was the devastating floods of 1993.
Meanwhile, the Cedar River is expected to crest at 21.5 feet on Thursday which would be an all-time record, exceeding the previous mark set in 1929.
