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.
Background
Flooding in Saskatchewan the previous summer,Storms, flooding add $161M to Sask. budget https://www.cbc.ca/news/canada/saskatchewan/storms-flooding-add-161m-to-sask-budget-1.889992 23 June 2011 Canadian Broadcasting Corporation August 20, 2010 in addition to heavy snowfall and a thick snowpack from the previous La Niña winter added to overflow on rivers across North America. In May 2011, heavy rains and thunderstorms driven by a series of cut off lows migrating westward triggered more flooding on watersheds in the southern Prairie Provinces, as some communities received nearly the annual rainfall in less than two months.

Also lake levels at Lake Manitoba will continue to be high or may even rise more due to the high flows on the Souris River that flows into the Assiniboine east of Brandon near Treesbank. The province has stated that the flood protection and the Portage Diversion will be pushed to their limits again.
At least 85 families were evacuated from Souris, Manitoba by June 27. On July 2, the army from CFB Shilo was sent in to help with the sandbagging and building up of dykes. The river crested at Melita on July 4, at Souris on July 5 and Wawanesa on July 6. With dry weather the peak levels were a little lower than forecast and the dikes held. See the record from Manitoba Water Stewardship's daily flood report for July 7.
