2011 Souris River flood

[3] The Souris River begins in southeastern Saskatchewan, flows southeast into North Dakota, then to southwestern Manitoba.

The flooding affected Saskatchewan and North Dakota; notably in Minot, where it overtopped levees and caused the evacuation of about 11,000 residents.

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.

[6] However, even as the flooding continued in northern Saskatchewan, Alberta, and the Northwest Territories, significant fires burned while the weather remained dry and lightning was able to spark new blazes.

[7] On June 17, Weyburn, Saskatchewan became one of 19 provincial communities to declare a state of emergency from the severe flooding, after a power outage caused the failure of the city's waste treatment plant; Saskatoon, surrounding the South Saskatchewan River, also experienced street-level floods.

[9] By June 19, a dike breach flooded the village of Roche Percee, Saskatchewan, forcing about 150 residents to evacuate.
