The Mississippi River’s rising water levels will force the U.S. Army Corps of Engineers to shut down multiple locks on the shipping waterway for the second time this month, from central Iowa to central Missouri, CNBC reports.
The river, a key channel for barge traffic, is already above flood stage at numerous locations following heavy rains, with more precipitation expected for the region.
Lock 12 near Bellevue, Iowa, was expected to close early on June 27, along with locks 16 and 17 further downriver, said Ron Fournier, spokesperson for the Army Corps’ Rock Island, Ill., district, in an interview with a CNBC reporter. Locks 13, 18 and 20 through 22 were expected to close between June 29 and July 2, he added.
At Lock 24 in Clarksville, Mo., the river was expected to hit the lock closure stage around July 4 or 5, said Michael Petersen, the corps’ St. Louis District spokesperson.
Neither had a reliable forecast for reopening the locks because of unpredictable weather.
