CORALVILLE, Iowa — Coralville Lake continues to rise and the water will soon overtake the beaches and some campsites, according to the Army Corps of Engineers.
The lake is currently nearly 10 feet above its normal summer pool of 683 feet (above sea level) and rising. Next week the lake is expected to crest around 700 feet, which would put the Sandy Beach and Sugar Bottom beaches completely underwater. The West Overlook day use beach goes completely underwater at around 703 feet. Corps officials say there will be little to no beach left at West Overlook given current models.
The crest is expected on July 3, just in time for the Fourth of July weekend.
“Probably not going to be a good time to come lay on the beach,” said Janet Lewis, supervisory park ranger.
Lewis said she expects boat ramps at West Overlook and Mehaffey Bridge to remain open, although others will close. A few dozen campsites at West Overlook and Sugar Bottom also will be effected, Lewis said.
The lake is currently filling up as water from the Iowa River enters at a rate of nearly 8,500 cubic feet per second. The outflow has been cut to just 1,000 cubic feet per second to help ease flooding concerns on the Mississippi and Cedar Rivers.
Coralville Lake Operations Manager Dee Goldman said Coralville Lake still has well over half of its available storage capacity. The emergency spillway sits at 712 feet.
