The Army Corps of Engineers expects lock and dam closures on the upper Mississippi River, including Locks 12, 16 and 17, due to flooding in Minnesota, Iowa and Wisconsin. Closures are likely to halt cargo flow within the next week, and floodwater is expected to reach the St. Louis harbor over the weekend.
