No evacuation orders expected as Calgary river water levels reach peak, officials say

Though this week's storm has already led to widespread power outages, fallen trees and water pooling on city streets, city officials say they believe they're equipped to handle whatever the next few days bring.

Though this week's storm has already led to widespread power outages, fallen trees and water pooling on city streets, city officials say they believe they're well-equipped to handle whatever the next few days bring.

The city remains under a state of local emergency called on Monday.

While the Environment Canada rainfall warning for Calgary ended on Wednesday, the weather alerts remain in place for a swath of southern and central Alberta north, east and south of Calgary.

During a media availability held Tuesday afternoon, Susan Henry, chief ofthe Calgary Emergency Management Agency, said city officials will continue to monitor the river.

Calgary is not out of the woods yet, and the city will continue to monitor water conditions.

With precipitation in Calgary significantly less than the upper end of what had been forecasted, officials say incoming flows should be able to be managed without any localized flooding or evacuations.

"We do not have any evacuation orders, and we do not believe we will need to issue any evacuation orders in the next few days," Henry said.

But given the dynamic weather conditions and how quickly conditions on the river can change, Henry offered a caveat "We're not out of the woods yet."

That closure was done for the construction of a temporary berm that runs across Memorial Drive. City officials decided to take that mitigation measure Monday given the forecast in the coming days.

"There isn't flooding occurring yet, but it's a protective measureshould the water level come to what we think it might," Henrytold the Calgary Eyeopeneron Tuesday morning.

City officials previously lowered the Glenmore Reservoir to attenuate the water coming in. For that reason, officials weren'tconcerned about the Elbow River as of Tuesday morning keeping in mind that things could change as forecasts change.

"Things are definitely under control. We learned a lot in 2013," said Henry, referring to thecombination of rapidly melting snow in the mountains and seemingly endless rainfall that caused $5 billion in damages and claimed five lives in southern Alberta in 2013.

"The fact that we're talking about this days before the peak of the river is expected is actually really good news."

On Monday, MayorGondek said the state of local emergency allows police and fire departments to go door-to-door in the event of an evacuation.

It also gives the city's water services team access to property to protect critical infrastructure, and secure supplies quickly if need be.

The town of High River, which was devastatedduring the 2013 floods, was previously under a flood warning. That was downgraded to a high streamflowadvisory.

The town has been building up flood mitigation infrastructure since 2013.

"The emotions are still raw in this town, and I don't think that'll go away for a lot of people for the rest of our lives," said High River Mayor Craig Snodgrass during a media availability held Tuesday.

"It's just making sure we're always on top of things we can never be complacent."

In a warning issued Tuesday shortly after 3:30 p.m., Environment Canada said periods of heavy rain would continue throughout the evening before ending on Wednesday.

The heaviest rain is expected to fall to the west, the agency said, with rainfall totals of 150 mm or more possible along the Foothills and in the front range of the Rocky Mountains.

On Tuesday, the Municipal District of Bighorn issued a local state of emergency.

In a media availability, Alberta Minister of Environment and Parks Jason Nixon reiterated that the provincial governmentis on stand-by to provide assistance to affected communities as needed.

He added that municipalities can request flood mitigation equipment from provincial stockpiles through the Alberta Emergency Management Agency.

Lisa Jackson, executive director of environmental emergency management for Alberta Environment and Parks, said that since Sunday, the heaviestamounts of rain have beenobserved in areas west of Sundre, west of Calgary and south ofPincher Creek, with some local amounts ofup to 110 millimetres.

Sundre is locatedabout 110 kilometres northwest of Calgary. Pincher Creek is roughly 100 kilometres west of Lethbridgein the southwest corner of the province.

Jackson also reported that several areas have been downgraded from a flood watchto a high streamflow advisory: the Bow River at Banff, Canmore and Exshaw, tributaries to the Bow River upstream of Calgary, as well as theElbow River, Highwood River and Fish Creek.

The Red Deer River was downgraded from a flood warning to a flood watch, although a flood warning remains in place for the Little Red Deer River.
