IOWA CITY, Iowa (AP) — The University of Iowa and cities along the Iowa River are finalizing flood preparations as rising waters threaten to inundate the area next week.
A projection released Thursday showed that Coralville Lake, a reservoir built to control flooding on the river, would crest next week less than one foot below its emergency spillway. That's significant because Iowa City, Coralville and other areas downstream can largely manage flooding as long as water doesn't top the spillway.
The U.S. Army Corps of Engineers, which manages Coralville Lake, said it is opening the gates to increase the outflow. The lake's taking in far more water than it is letting out, and is at 704 feet and rising. It's expected to crest July 10 or 11 at 711.3 feet, below the 712 foot spillway.
