IOWA CITY, Iowa (AP) — Eastern Iowa communities fighting flooding along the Iowa River are getting good news after a new projection shows Coralville Lake is less likely to top its emergency spillway.
A projection released Monday shows the lake, six miles north of Iowa City, will crest Thursday at 710 feet, two feet below the spillway.
The U.S. Army Corps of Engineers manages the outflow of the lake, which was built as a flood-control barrier. When the water tops the spillway, it becomes harder to manage and Coralville, Iowa City and cities downstream such as Columbus Junction can face more damaging floods.
Johnson County emergency management spokesman Terrence Neuzil says “the news keeps getting better.” He noted that days ago, the water was projected to top the spillway.
