Flooding in western Canada on Friday forced the evacuation of downtown Calgary and several towns in southern Alberta, where up to four people have died after days of rain and melting mountain snow inundated major rivers.

Although 230,000 people typically work in the city’s core on Fridays, officials said the majority did not show up, CTV reported.

The city’s iconic sports area, the Saddledome, which is to host the annual Calgary Stampede in two weeks, had water up to the 10th row, as the Bow River continued to rise.

The Elbow River has crested, said Calgary Mayor Naheed Nenshi.
