Grain shipments on the Mississippi River could come to a standstill in the thick of harvest after rainfall in the upper Midwest flows south.
According to the Army Corps of Engineers, four locks may close temporarily on the river, preventing grain shipments from moving south.
The locks are 16 in Muscatine, Ia.; 17 in New Boston, Ill.; 18 in Burlington, Ia.; and 20 in Canton, Mo.
The Corps anticipates shutting down traffic on Saturday or Sunday, depending on the flooding crest. The locks would be out of operation for “a coupe days.”
Excessive rain in northern Iowa, southern Minnesota, and western Wisconsin swamped farmland last week, bringing near-record flooding in Cedar Rapids, Ia., the state’s second-largest city.
The Cedar River dumps into the Mississippi River, and is 10 feet above flood stage.
