USDA's Grain Transportation Report said American Commercial Barge Line had no boats above St. Louis on April 24 due to flooding, with locks above Lock 17 closed for about three weeks. Barge freight rates are below normal due to flooding and slow export sales, and closures could extend to Lock 22 around May 5.
Closures halt grain and fertilizer movement on the upper river, and below-normal barge rates signal weak river demand, weighing on Midwest cash grain values while raising delivered fertilizer costs.
