Floods in Canada

Someone had better point out to Stephen Harper the connection between this and tar sands and global warming

Flood disaster in Alberta, Canada

Rivers fed by torrential mountain rains spilled across the prairies of southern Alberta Friday, turning Calgary streets into rivers and threatening to wash away a similarly monstrous flood in 2005 as the western Canadian province's most costly natural disaster.

Calgary Mayor Naheed Nenshi said the Bow and Elbow rivers were carrying as much three times as much water through Calgary as they did during that flood, which obliterated roads, chased residents from their homes and drowned livestock on the way to causing more than $400 million in damages.

"The Bow River looks like an ocean at the moment," he said.

Even as Calgary was dealing with the brunt of the flooding, residents downstream of the city -- backed by engineers rushed into place by the Canadian military -- braced for the coming floods.

Communities including Red Deer, Medicine Hat and Lethbridge have already declared emergencies ahead of the expected flooding, said Alberta Premier Alison Redford, hours after she had toured flooding in predawn darkness.

"I've got to tell you, standing on a bridge, in the dark, when the power is out, listening to the roar of the river is terrifying," she said.

Calgary residents seemed alternately shocked by the flooding and willing to take it in stride.

"I don't think anybody's ever seen water flow through the streets," Calgary resident Rylan Broadbent told CNN Friday after evacuating his apartment building in the Erlton neighborhood, next to the overflowing Elbow River.

Others were more melancholy about the scope of the flooding, which forced about 75,000 residents out of their homes and left the heart of the city largely deserted.

Clean water continued to flow to homes, but power was out in portions of the city-- famous for the annual Calgary Stampede rodeo. Some shelters were filled to capacity, Calgary officials said Friday. Schools were closed.

Officials said most of the city's many bridges were holding against the water, but at least one was under water and another had washed out. The city zoo closed and began moving animals to safer locations.

Meanwhile, Calgary police said they were patrolling evacuated areas to ensure that vacant homes and businesses would remain as safe as possible.

"Not going to lie, it's a bit emotional seeing this happen to my/our city," local radio host Roger Kingkade posted to Twitter.

Emergency officials praised the calm, orderly evacuations overnight of 25 Calgary neighborhoods, but pleaded with gawkers to stay away from flooded areas and asked residents to stay off the telephone so emergency workers could be sure to get a connection.

The emergency in Calgary comes a day after rain-swollen rivers burst from their banks in southern Alberta, ripping out roads, swallowing houses and cutting off communities.

Authorities declared a state of emergency in several cities, including the mountain town of Canmore, where on Thursday, raging water tore out a portion of the Trans-Canada Highway.

"Like everything, everything, is destroyed there -- our homes, like everything," Alberta resident Melanie Atkinson, who lost her home in the flooding, told Canadian broadcaster CBC.

Rescue crews used heavy construction equipment to rescue people from homes and businesses Thursday in High River, the network reported.

Canada's military was pitching in with helicopters and other assets to help local officials with rescue and evacuation efforts, Prime Minister Stephen Harper sai

"Our thoughts and prayers are with those families who have been affected by the serious flooding in Calgary and Southern Alberta," Harper said, adding that the federal government would provide "any and all possible assistance.

No deaths or injuries have been reported.

The flooding was caused by a slow-moving storm that dumped 154 millimeters (more than 6 inches) of rain on the region from Wednesday to Thursday, CNN meteorologist Sherri Pugh said. As much as another inch of rain, about 25 millimeters, is possible northwest of Calgary on Friday, and yet another front is expected Monday, bringing the threat of more rain.

Calgary, near the Canadian Rocky Mountains, is perhaps best known for its rodeo, held each July. More than 1.4 million people attended last year, organizers say.

This year's Stampede events are due to begin in 13 days. It was unclear if the flooding would affect the event, but organizers did say on their website that other events scheduled at the park where the Stampede is held have been canceled through Sunday.

Calgary authorities are using the park as a staging area for flood response efforts.
