The U.S. Army Corps of Engineers is closing its three twin cities locks to commercial navigation as flows surpass 40,000 cubic feet per second, or cfs. The three locks were
closed to recreational boaters Sunday, April 27, when flows exceeded 30,000 cfs.
Based on National Weather Service forecasts, flows are expected be more than 40,000 cfs at the upper three locks until sometime next week. The locks will be closed to recreational traffic until flows are below 30,000 cfs.
According to the Corps' lock and dam regulation manual, the district is required to close the lock and dams to recreational traffic at 30,000 cfs because the high flows are unsafe. Commercial traffic at these locks is shut down at 40,000 cfs.
Locks and dams in the Winona area remain open for both commercial and recreational traffic but boaters are advised to exercise caution and be vigilant...and wear life jackets.....
