with the Souris River highlighted
The 2011 Souris/Mouse River flood in Canada and the United States occurred in June and was greater than a hundred-year flooding event for the river.[1][2] The US Army Corps of Engineers estimated the flood to have a recurrence interval of two to five centuries.[3]
The Souris River begins in southeastern Saskatchewan, flows southeast into North Dakota, then to southwestern Manitoba. It is a tributary of the Assiniboine River, which it meets near Treesbank, Manitoba, and flows east to meet the Red River of the North in Winnipeg.
The flooding affected Saskatchewan and North Dakota; notably in Minot, where it overtopped levees and caused the evacuation of about 11,000 residents. The flooding in Minot was worse than the 1969 and 1881 floods; many other towns along the river were affected and many acres of farmland were inundated.
