The U.S. Army Corps of Engineers, St. Paul District, continues to closely monitor water levels on the Upper Mississippi River as drought conditions continue across Iowa, Minnesota, and Wisconsin. The low water is not affecting shipping conditions on the river and navigation continues.
"Low flow is exactly the conditions for which the locks were built," said Dan Fasching, St. Paul District water manager for the Upper Mississippi River. "The locks, combined with dredging efforts, are used to maintain navigable depths in the main channel."
