2011 Red River Flood, North Dakota, Minnesota, United States

Amphibex excavator icebreakers were at work breaking up ice flows on the Red River. Ice breakers and backhoes were to be strategically placed along the Red River Floodway, which might have needed to be opened before the ice was fully melted. Officials examined past ice jams and provided contingency plans if the Floodway jammed upstream of bridges or on tight corners.
On Easter Sunday, April 12, Winnipeg was clear of ice blocks and ice jams. Sightseers traveling by car, boat, kayak and anyone ignoring road closures were being ticketed by the Royal Canadian Mounted Police as they were hampering ice clearing operations. Residents of the rural municiplaites of St. Andrews and St. Clements were given evacuation alerts on Good Friday. Some chose to remain behind, and rescue efforts commenced for them over the Easter week-end. Homes were smashed in and knocked off their basements and footings by 7-foot-high (2.1 m) sheets of ice.
