(NAFB.com) – The U.S. Army Corps of Engineers is actively working to monitor flood conditions throughout the Upper Midwest, including in Minnesota, after heavy rains. The Engineers’ water managers currently have all the dam gates above the water from Lock and Dam 2 in Hastings, Minnesota, to Lock and Dam 10 in Guttenberg, Iowa. The gates are not needed to maintain the minimum nine feet of depth with the current conditions. “Because the recent rain events fell with the Minnesota River basin, the rain adds more water to the Mississippi River and will take several weeks to drain,” says Dan Fasching, St. Paul Corps of Engineers water manager. “Any additional rains during the next few weeks have the possibility to increase the flood risk.” Further south near La Crosse, Wisconsin, Corp officials closed Blackhawk Park on June 21 due to recent heavy rains and high river levels.
