Floodwaters that devastated much of southern Alberta left at least three people dead and forced officials in the western Canadian city of Calgary on Friday to order the evacuation of its entire downtown, as the waters reached the 10th row of the city's hockey arena.
Canadian Prime Minister Stephen Harper called the level of flooding "stunning" and said officials don't know yet if it will get worse, but said the water has peaked and stabilized and noted that the weather has gotten better.
Overflowing rivers washed out roads and bridges, soaked homes and turned streets into dirt-brown waterways around southern Alberta. Royal Canadian Mounted Police Sgt. Patricia Neely told reporters three were dead and two bodies were recovered. The two bodies recovered are the two men who had been seen floating lifeless in the Highwood River near High River on Thursday, she said.
Harper, a Calgary resident, said he never imagined there would be a flood of this magnitude in this part of Canada.
"This is incredible. I've seen a little bit of flooding in Calgary before. I don't think any of us have seen anything like this before. The magnitude is just extraordinary," he said.
"We're all very concerned that if gets much more than this it could have real impact on infrastructure and other services longer term, so we're hoping things will subside a bit."
Calgary Mayor Naheed Nenshi said the water levels have reached a peak, but have not declined.
"We've sat at the same level for many, many hours now," Nenshi said. "There is one scenario that would it go even higher than this, so you'll either see the Bow river continue at this level for many hours or you will see it grow even higher and we're prepared for that eventuality."
Twenty-five neighborhoods in the city, with an estimated 75,000 people, have already been evacuated due to floodwaters in Calgary, a city of more than a million people that hosted the 1988 Winter Olympics and serves as the center of Canada's oil industry.
Alberta Premier Alison Redford said Medicine Hat, east of Calgary, was under a mandatory evacuation order affecting 10,000 residents. The premier warned that communities downstream of Calgary had not yet felt the full force of the floodwaters.
About 350,000 people work in downtown Calgary on a typical day. However, officials said very few people need to be moved out, since many heeded warnings and did not go to work Friday.
A spokesman for Canada's defense minister said 1,300 soldiers from a base in Edmonton were being deployed to the flood zone.
Police were asking residents who were forced to leave the nearby High River area to register at evacuation shelter. The Town of High River remained under a mandatory evacuation order.
In downtown Calgary, water was inundating homes and businesses in the shadow of skyscrapers. Water has swamped cars and train tracks.
The city said the home rink of the National Hockey League's Calgary Flames flooded and the water inside was 10 rows deep. That would mean the dressing rooms are likely submerged as well.
"I think that really paints a very clear picture of what kinds of volumes of water we are dealing with," said Trevor Daroux, the city's deputy police chief.
At the grounds for the world-famous Calgary Stampede fair, water reached up to the roofs of the chuck wagon barns. The popular rodeo and festival is the city's signature event. Mayor Nenshi said it will occur no matter what.
About 1,500 have gone to emergency shelters while the rest have found shelter with family or friends, Nenshi said.
The flood was forcing emergency plans at the Calgary Zoo, which is situated on an island near where the Elbow and Bow rivers meet. Lions and tigers were being prepared for transfer, if necessary, to prisoner holding cells at the courthouse.
Schools and court trials were canceled Friday and residents urged to avoid downtown. Transit service in the core was shut down.
Residents were left to wander and wade through streets waist-deep in water.
Newlyweds Scott and Marilyn Crowson were ordered out of their central Calgary condominium late Friday as rising waters filled their parking garage and ruptured a nearby gas line. "That's just one building but every building is like this," he said. "For the most part, people are taking it in stride."
Crowson, a kayaker, estimated the Bow River, usually about four feet deep, is running at a depth of 15 feet (4.57 meters).
"It's moving very, very fast," he said of the normally placid stream spanned by now-closed bridges. "I've never seen it so big and so high."
It had been a rainy week throughout much of Alberta, but on Thursday the Bow River Basin was battered with up to four inches (100 millimeters) of rain. Environment Canada's forecast called for more rain in the area, but in much smaller amounts.
Calgary was not alone in its weather-related woes. Flashpoints of chaos spread from towns in the Rockies south to Lethbridge.
More than a dozen towns declared states of emergency. Entire communities, including High River and Bragg Creek, near Calgary, were under mandatory evacuation orders.
Some of the worst flooding hit High River, where an estimated half of the town's residents experienced flooding in their homes.
Military helicopters plucked about 30 people off rooftops in the area. Others were rescued by boat or in buckets of heavy machinery. Some even swam for their lives from stranded cars.
Further west, in the shadow of the Rocky Mountains, photos from the mountain town of Canmore depicted a raging river ripping at house foundations.
