CORALVILLE (KWWL) -

Officials are warning about the potential for flash flooding Monday night into Tuesday in Johnson County -- and it's not the only flooding potential they are watching.

Emergency management officials are keeping a close eye on the water levels at Coralville Lake, after heavy rains throughout the Iowa River basin this spring.

On Monday, the U.S. Army Corps of Engineers increased the discharge rate to 6,000 cubic feet per second. 

"As the lake gets to a different level, then we go into a different phase of operation," said Dee Goldman, operations manager at the Coralville Reservoir.

Officials are monitoring rainfall totals and forecasts overnight. The Army Corps of Engineers is considering increasing the discharge rate further.

The most recent projections have Coralville Lake cresting inches below the 712-foot spillway in June.

"We're getting close, so obviously we're going to try to do everything that we can," Goldman said. "Hopefully, with a little cooperation from Mother Nature, it will give us some time to get rid of the water."

Dwight Bode owns property on Stewart Road Northeast, traditionally one of the first areas to flood.

His property was one of many inundated with water during the historic floods of 1993 and 2008.

"You're checking almost every day when it's raining like this," Bode said.

Residents have already begun asking about sandbags.

Many living in the neighborhood are waiting to see if rising lake levels prompt the engineers to increase outflow at the reservoir further.

"You don't really know now if you're going to get completely flooded out or not," Bode said. "It's up to Mother Nature now."

Emergency management officials are meeting Tuesday about potential next steps at Coralville Reservoir.
