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 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 of the Calgary Emergency Management Agency, said city officials will continue to monitor the river.
"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."
Calgary Mayor Jyoti Gondek says the city caught a break as some of the forecast rain in the mountains fell as snow, which helped to reduce the amount of runoff caused by the rainstorm.
She said 25 mm of the precipitation officials thought would be rain was, in fact, snow.
According to the city, Calgary has received 75-100 mm of precipitation so far. The system is starting to taper off with up to 40 mm of rain expected today.
Officials say rainfall in the Bow and Elbow Rivers was significantly below the upper end of what had been forecasted.
City officials have closed a portion of Memorial Drive to construct a temporary berm. Construction is progressing well and will be completed later on Tuesday.
During that time, Memorial Drive will remain closed until the peak of the event has passed through the city.
There is pooling water on some Calgary roadways at present.
As of 4 p.m. Tuesday, Bowness Park, St. Patrick's Island and Prince's Island Park have closed.
Environment Canada issued a wind warning shortly after 11:30 a.m., cautioning that the wet ground from ongoing rain could lead to an increased risk of tree falls.
Enmax said it was working to restore power to various parts of the city. More than 6,500 Calgarians were experiencing outages for a period of time, though power has since been restored to some communities.
Altadore, Banff Trail, Bankview, Brentwood, Bridgeland/Riverside, Charleswood, Cliff Bungalow, Collingwood, Crescent Heights, Elbow Park, Greenview, Highland Park, Lake Bonavista, Mount Pleasant, Renfrew, Richmond, Scarboro, South Calgary, Spruce Cliff, Tuxedo Park, University Of Calgary, Upper Mount Royal and Winston Heights/Mountview were all experiencing outages as of 2:30 p.m.
The Tsuutʼina Nation was also experiencing an outage as of 2:30 p.m.
A flood warning previously issued for the Highwood River main stem from the town of High River to the Bow River confluence has been downgraded to a high streamflow advisory.
Plans to construct a permanent berm to protect the community of Bowness are paused. Officials are seeking an alternative solution.
Boating advisories are in place for the Bow and Elbow rivers. Recreation access to the Glenmore Reservoir is restricted.
Bowness Park, St. Patrick's Island and Prince's Island Park will be closed as of 4 p.m. on Tuesday
Sunnyside resident Colton O'Reilly said last night he received an emergency signal and is waiting to see what happens next.
"We're keeping our eyes on the river," he said.
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 measure should the water level come to what we think it might," Henry told the Calgary Eyeopener on Tuesday morning.
City officials previously lowered the Glenmore Reservoir to attenuate the water coming in. For that reason, officials weren't concerned 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 the combination 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, Mayor Gondek 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 devastated during the 2013 floods, was previously under a flood warning. That was downgraded to a high streamflow advisory.
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 government is 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 heaviest amounts of rain have been observed in areas west of Sundre, west of Calgary and south of Pincher Creek, with some local amounts of up to 110 millimetres.
Sundre is located about 110 kilometres northwest of Calgary. Pincher Creek is roughly 100 kilometres west of Lethbridge in the southwest corner of the province.
Jackson also reported that several areas have been downgraded from a flood watch to a high streamflow advisory: the Bow River at Banff, Canmore and Exshaw, tributaries to the Bow River upstream of Calgary, as well as the Elbow 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.
There is a new flood watch advisory in place for Waterton Lake, said Jackson.
