Heavy rainfall could cause additional flooding in areas along the Missouri River, where levees sustained heavy damage in March.
Additional rainfall could have significant downstream effects on levee systems along the Missouri River, the U.S. Army Corps of Engineers said.
“Protecting lives is our No. 1 priority,” said Col. Doug Guttormsen, Kansas City District commander for the Corps. “As localized rainfall continues and the flood storage capacity fills up, our team will individually assess each reservoir in our region, along with the projected weather forecast, to determine if and when water releases will be made.”
Releases from Gavins Point Dam were set to increase to 60,000 cubic feet per second beginning Thursday.
The decision comes after precipitation totaling between 2 to 5 inches fell over central Nebraska and much of South Dakota over the last several days.
In St. Joseph, the Missouri River was expected to crest above 21 feet and slowly begin to fall over the Memorial Day weekend. In Chillicothe, the Grand River was near major flood stage at 33 feet, while the Platte River near Agency was 26 feet.
Several roads remain closed in the region, including U.S. Highway 59 in southern Buchanan County.
