Calgary, other communities prepare for potential flooding along rain-swollen rivers


5 minute read

By Colette Derworiz in Calgary

Preparations for potential flooding were underway in Calgary and surrounding communities Tuesday as rainfall warnings continued and rivers swelled across southern Alberta.

Environment Canada said to expect rainfall totals of between 75 millimetres and 125 millimetres by Wednesday morning in parts of the province. The heaviest rainfall was predicted for the western region — 150 millimetres or more along the foothills and eastern slopes of the Rocky Mountains.

Some areas of Kananaskis Country, west of Calgary, had already received about 130 millimetres by Tuesday morning, said University of Saskatchewan hydrologist John Pomeroy, who has monitoring stations throughout the Rockies.

“They’ve got a lot more to come,” he said.

Pomeroy said that included headwaters of the Elbow, Highwood and Sheep rivers with higher stream flows coming.

The executive director of the emergency management branch of Alberta Environment said there’s more rain in the forecast overnight and the province’s river forecast centre continues to monitor the situation.

“We do update the forecast and the warnings and the advisories as the system progresses,” said Lisa Jackson, who noted snowfall instead of rain in the high mountains Monday helped to reduce the risk of flooding.

As a result, Alberta Environment downgraded flood watches on the Highwood River upstream of High River, Alta., and the Bow and Elbow rivers upstream of Calgary to high stream flow advisories.

Both communities were hit hard during flooding in 2013, which left at least five people dead and caused billions of dollars in damage across southern Alberta.

High River Mayor Craig Snodgrass said the town was keeping a close eye on the Highwood River.

“We are a long way away from anything that 2013 looked like,” he said Monday.

Calgary issued an advisory for both the Elbow and Bow rivers earlier this week and water levels were lowered in upstream reservoirs to make room for potential floodwater.

The city also declared a state of local emergency late Monday afternoon “out of extreme caution,” said Mayor Jyoti Gondek.

On Tuesday, winds up to 90 km/h caused broken trees, power outages and flashing traffic lights throughout the city.

Sue Henry, chief of the Calgary Emergency Management Agency, said crews were responding to calls as needed and officials continued to monitor river levels as the rain started to taper off.

“We’re not out of the woods yet,” she said. “Our state of local emergency remains in effect and we continue to monitor the conditions as we expect the rivers to crest in the coming hours.”

The city closed St. Patrick’s Island and Prince’s Island Park in the Bow River near downtown as a precaution, she said.

Sal Howell, who owns the River Café on Prince’s Island Park, said she was prepared for any potential flooding.

“This isn’t the first time for us,” she said. “We’ve been operating on Prince’s Island for 31 years and the island, of course, sits in the middle of the Bow River. It’s a beautiful park, but we are definitely in a floodway.”

Howell said she and her staff, as well as family and friends, spent Monday moving fresh produce and thousands of bottles of wine from the restaurant’s cellar to a safe place.

“We are hoping for the best, but gearing up for the worst.”

Howell said the restaurant had extensive flood damage in 2013, so they learned many valuable lessons.

City crews installed a Tiger Dam — flexible tubes that work as a flood barrier — Tuesday around the restaurant.

The city also closed Memorial Drive, a major east-west roadway along the Bow River, to build a temporary berm to help protect communities north of the river.

Francois Bouchart, director of water resources with the city, said the berm would be finished late Tuesday.

“It will remain in place until the peak of the event has passed through the city,” he said.

Saskatchewan landowners fight against illegal drainage washing out land, roads

Published on

WAWOTA, Sask. — Lane Mountney spreads a map over his kitchen table at his farmhouse in southeast Saskatchewan, pointing to yellow and orange arrows slithering across the document. 

Many of the arrows represent existing channels and ditches, moving across fields and out of wetlands to drain water. The arrows eventually make their way to a creek, causing what he describes as a deluge of problems downstream. 

“All these years, guys have gotten away with draining water and the next guy figures he can get away withit,” Mountney said in an interview at his farm near Wawota, Sask., about 200 kilometres southeast of Regina. 

“If this keeps going like it has, I don’t know what Saskatchewan’s going to look like in 10 years.”

Mountney’s map depicts what’s called the Wawken Drainage Project, a plan developed by the local watershed group that has since been taken over by the Water Security Agency, which is responsible for overseeing drainage in Saskatchewan. 

The project is nearly 14 square kilometres and contains 880 wetlands of various sizes representing a total of 2.4 square kilometres of water. 

A project document indicates that 88 per cent of these wetlands have been drained, partially drained or farmed. About 12 per cent remain intact.

Most of this water is supposed to flow into a creek that runs through a parcel of Mountney’s land. 

The plan developers believe the creek can handle the flows, but Mountney is not convinced. 

Last year, he and his wife, Sandra Mountney, dealt with flooding ontheir horses’ pasture. They decided not to use their well water at the time because it was yellow. 

“They were very excited to tell us that nobody inside the project area is going to lose acres, but they haven’t even looked at who’s going to lose acres miles down the line.” Sandra Mountney said. 

Brent Fry, who farms grain and livestock, said it’s common for his land to flood for three days when people upstream get 50 millimetres of rain. 

He said it has caused roads and access points to erode.

“There are about four farms out there and all they’re doing is draining whether they’ve got permission or not,” Fry said. “I don’t even know what to do because the government’s not doing anything — they’re siding with the big guys.”

Farmers have drained water in Saskatchewan for generations and many have done so illegally by digging ditches without permits.  

Most producers drain because it allows them to grow more crops, helping them pay for land that has become increasingly expensive. However, it has caused yearly flooding for people downstream. Roads also wash out and habitat gets lost.

At the Saskatchewan Association of Rural Municipalities convention in February, reeves passed a resolution asking the Water Security Agency to require those who are illegally draining to remediate their unapproved works. 

Saskatchewan legislation requires upstream landowners to receive permission from those downstream when they want to drain, but many say that’s not happening. 

Sandra Mountney said the Water Security Agency hasn’t been taking concerns seriously.

“It’s hard to know who’s really protecting our waterways,” she said.

The Wawken project began about three years ago but hasn’t been completed. It’s among many drainage projects underway.

Daniel Phalen, a watershed planner, worked on the project as technician before he left for another job. 

He said landowners had been draining water with no permits before the plan. His job was to determine how many wetlands were drained and what works had already been done. 

Phalen said the plan was to put in structures that would slow down the drainage to reduce problems downstream. 

It’s unclear what work had been done on the Wawken project to mitigate flows since Phalen left. The Water Security Agency did not respond to a request for comment.

Phalen said projects can get held up if affected landowners don’t come to an agreement. Expropriation is allowed but it’s rare, he said.  

Another nearby drainage plan, known as the Martin project, has stalled because of landowner concerns.

Researchers have estimated Saskatchewan has lost half of its total wetlands over time for crop production. 

Phalen, who also worked on the Martin plan, said it was concerning to see the number of wetlands sucked out. 

“The Water Security Agency doesn’t have the manpower to do much about it,” Phalen said. “There’s such low enforcement already that if they had any policies in place, people would just drain anyways. It’s kind of a scary problem to be in.”

Sandra Mountney said she’s worried about losing wetlands because they help recharge groundwater supplies and filter contaminants — particularly important when it’s dry. 

The Water Security Agency has released a drainage management framework that aims to prevent flooding and ensure Saskatchewan retains a “sufficient” number of wetlands. 

Leah Clark, the Interim Executive Director of Agriculture Water Management, told attendees at a Saskatchewan Farm Stewardship Association meeting earlier this year that 43 per cent of wetlands are retained within approved projects. She added the province has “thriving” wildlife populations.

However, she said under the policy, landowners would be able to select which wetlands to retain.

“It will achieve a working landscape for landowners to continue to use their land for farming and ranching. This approach will allow for new development while retaining current drainage,” she said. 

Phalen said Saskatchewan could look to Manitoba for solutions to retain wetlands. 

Manitoba has historically drained most of its wetlands in the agricultural regions, he said, but the province has since developed a policy where landowners are paid for retaining them. 

“You know, $100 an acre is not a ton of money, but it’s another incentive to help producers,” he said. “It’s such a complex problem where you got this huge financial incentive to drain.”

Lane Mountney said regulations just need to be enforced. 

“It’s almost too late,” he said. “They should have been out there checking stuff before we got this point.”
