Conditions on the Upper Mississippi River are improving but remain at elevated levels, the U.S. Department of Agriculture reported today. Several Mississippi River locks were closed because of high water in late June and reopened by July 1.

Barge traffic through St. Louis Harbor remains restricted to daylight only, and high river levels are also preventing loading operations on the lower Illinois River, the USDA said in today’s Grain Transportation Report. During the week ending July 4, there was no reported barge traffic on the Illinois River at LaGrange Lock and Dam (the last lock on the Illinois River).

Barge operators report that some loading will begin this week on the upper Illinois River, while loading operations on the lower Illinois could resume next week, the GTR said.
