The U.S. Coast Guard says all traffic on the Missouri River from about 50 miles south of Omaha, Nebraska, downstream to St. Joseph, Missouri, has been shut down due to the river’s high water levels. The order came Friday. The Coast Guard and U.S. Army Corps of Engineers also requested all river vessel operators create as little wake as possible between St. Joseph downstream to Kansas City to minimize levee damage.

Officials say the restrictions will be lifted as soon as flooding conditions improve. The restrictions come as the river reached moderate flood stage at nearly 32 feet on Friday at Omaha, where it’s expected to crest at nearly 34 feet on Monday, according to the National Weather Service. The river is expected to crest at St. Joseph on Tuesday at just over 30 feet. Major flood stage at St. Joseph is 27 feet.
