The U.S. Army Corps of Engineers closed three lock and dams to recreational boats on Monday Morning, saying increasing high water flows on the Mississippi River are unsafe.
The following locks and dams are likely to be closed for a week or longer:
The recent heavy rains rapidly increased the water flow past 30,000 cubic feet per second, and the National Weather Service forecasts indicate it will likely take a number of days for the flows to fall back to safe levels for smaller boats.
The U.S. Army Corps of Engineers says the recent rains are also expected to contribute to a dramatic rise in the lake water levels near Grand Rapids since 3-4 inches of rain fell in the area over the past four days.
Officials say Pokegama Lake could rise as much as one to two feet in the next few days. Property owners are being asked to move boat lifts and docks to higher ground.
The lake is a flood-controlled reservoir, and flooding concerns downstream have prompted the Army Corps to slow the release of water. Engineers will continue to monitor the reservoir and the river both up and downstream.
