Low water levels on the Mississippi River from northern Minnesota to northern Illinois have caused transport problems. Only one barge at a time can pass certain stretches, and some barges have grounded on sandbars.
Officials said the lower flows are linked to a lack of rain that scientists say is likely driven by climate change.
Single-file barge traffic and groundings reduce barge capacity and push up freight costs for grain moving from the Upper Mississippi to Gulf export positions. Those costs feed into basis and feed ingredient prices in the Midwest.
