2011 Assiniboine River Flood
The 2011 Assiniboine River flood was caused by above average precipitation in Western Manitoba and Saskatchewan. This was a 1 in 300 year flood that affected much of Western Manitoba. The flooding in Manitoba was expected to mostly involve the 2011 Red River Flood but instead the more severe flooding was found on the Assiniboine in the west. Early signs The 2011 flood really started in the fall of 2010 with several major rainfall events and generally wet conditions. Initially, it was predicted that the flood along the Assiniboine River would be similar to the flood of 1995. During the winter of 2010–2011 the Shellmouth Reservoir was emptied in preparation, to store water for the coming spring flood. With more and more precipitation, the estimates on the flood were revised upwards. The first major settlement to experience the floodwater was St. Lazare, Manitoba which was located near the confluence of the Assiniboine River and Qu'Appelle River.

2011 Souris River Flood
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. The US Army Corps of Engineers estimated the flood to have a recurrence interval of two to five centuries. 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, in addition to heavy snowfall and a thick snowpack from the previous La Niña winter added to overflow on ...
