Alberta’s environment minister says it’s not an emergency yet, but a deep snowpack and heavy spring rains may be needed to avoid serious water problems in the new year. Doug Vaessen explains.
How a U.S. river swelled catastrophic floods in B.C. — and why little can be done to stop it happening again
Two years ago, what would soon become a historic atmospheric river made landfall in B.C. as nearly a month's worth of rain pounded down on the province in less than 48 hours. Over a terrifying few days, mass evacuations were ordered, thousands of animals were lost, and homes were flooded to their upper levels. Every highway connecting the Lower Mainland to the rest of the province was badly damaged or destroyed.
Cities that soak up water like sponges are more climate-resilient
Engineers must design with the risk of flooding in mind. But my research shows that if we also design with the concept of rain as a precious resource and plan to soak it up, floods will do less damage. These design ideas bring many co-benefits including cooling spaces in hot summers, cleaner air and healthier bodies, resilient food and flower gardens and access to more green space, which is accepted as beneficial for our mental health.
Less snowpack, low rainfall, higher demand. Experts offer answers on low water levels in Lethbridge
Water levels in the Oldman River reservoir are the lowest they've ever been since its construction in the early 1990s. The reservoir and the river are responsible for supplying water to a number of local communities, including Lethbridge. The City of Lethbridge said in a release that while there's no immediate danger of being left without an adequate supply of drinkable water in the city, the lower-than-average water levels across southern Alberta is something they are watching closely.
'Sponge cities': An absorbing idea in the face of climate change
At the bottom of a slope in a dense Montreal neighbourhood, there's a new park with benches, an open field and a playground — along with two small pedestrian bridges. When there's heavy rain, water rushes down the streets and sidewalks into the green space, forming a small lake beneath the overpasses, in a carved-out area filled with grasses, shrubs and rocks. In the days that follow, the water slowly seeps into the soil and stormwater system. It's all been engineered to prevent flash flooding in nearby streets and homes, while nourishing the vegetation in the park.
Fall's cold arrival hasn't shaken off the impact of B.C.'s months-long drought
Climate geoscientist Joseph Shea didn't have to go far to find evidence of what he calls "exceptional'' hot and dry weather in British Columbia this year. He says he was still gathering raspberries in his garden in Prince George, B.C., last week as temperatures neared 20 C, at a time when the historical average maximum is about 9 C.
Montreal building more sponge parks, sidewalks to soak up heavy rainfall
The city of Montreal is planning to build more urban "sponge" infrastructure to protect against future flood waters brought on by climate change. The announcement Tuesday came as Montreal once again found itself drying out after heavy rainfall pummelled the city in the early morning. The city plans to build 30 sponge parks and 400 more sponge sidewalks by 2025 — green spaces that naturally absorb excess rainfall instead of draining the water directly into neighbourhood sewers.
New York City: State of emergency declared over flash flooding
More than 2.5in of rain was reported in one hour in Brooklyn Navy Yard. In a virtual briefing, New York's chief climate officer Rohit Aggarwala said that the city's sewage system was only designed to handle 1.75 inches an hour. "It's no surprise that parts of Brooklyn have borne the brunt of this," he said.
Homeowners on flood-prone Windsor street call for fixes to overburdened storm sewers
Feelings of overwhelming fear and anxiety hit Alicia Hennessey, Amanda Dunfield and Jennifer Moore every time a rainfall warning is issued for their area. The women are neighbours and live with their families on Stannus Street in downtown Windsor, N.S. — their homes three in a row. For years they've each dealt with repeated flooding caused by problems with the town's combined sewage and storm water system.
'We're hoping for some more rain': Extremely low N.W.T. water levels raise concerns about the future
Water levels in rivers and lakes of the central and southern Northwest Territories are at — or near — record lows this year after an extremely hot and dry stretch lasting months. "It's been steadily decreasing all summer and, as a result, the Mackenzie River downstream is also extremely low and record low at different locations," said Ryan Connon, a hydrologist with the Government of the Northwest Territories.
Extreme weather costs are pushing rural Ontario towns to the financial brink
The mayor of Glencoe, Ont., says the cost of cleaning up and repairing the damage from Wednesday's deadly rainstorm has pushed his rural community to ask the province for financial relief. Environment Canada said Wednesday the town received 135 millimetres of rain during a downpour that turned driveways into ponds, roads into streams and filled basements with sewage.
What happens when millions of litres of sewage-tinged water overflows into the Ottawa River?
Unquestionably, dumping more than 300 million litres of sewage-tinged water into the Ottawa River stinks. But it’s hard to imagine what that much sewage overflow actually does to a waterway. So, we asked the experts about the impact of the city’s decision to release that volume of water following the massive Aug. 10 storm—and what can be done to prevent this in the future.
After 6-alarm Etobicoke fire, crews assessing how much runoff in Lake Ontario: ministry
Cleanup crews are trying to determine how much runoff from an industrial fire in Etobicoke a week ago has made its way into Lake Ontario, the province's environment ministry says. The ministry has said the runoff is affecting two waterways, Mimico Creek and Humber Creek, and containment measures have been in place since August 11 in both creeks. On Friday, it said while measures along Mimico Creek were reinforced Wednesday, Thursday's rain night enabled the spill to move further down Mimico Creek.
No 'feasible' solution to sewage overflow from Ottawa storms
When Ottawa was hit by more than 75 millimetres of rain last week it filled a $232 million sewage tunnel, sending nearly 316 million litres of raw sewage into the Ottawa River. Unfortunately, it's not unexpected or unusual. "It was always known that if there were very large storms the city would be faced with a choice of either flooding sewage into people's basements or into the river," explained Dianne Saxe, a former environmental commissioner and the last person to hold that provincial post.
'The saving grace for agriculture': Farmers look to irrigation amid climate woes
Sean Stanford's wheat farm just south of Lethbridge, Alta. falls within the far left corner of Palliser's Triangle — an expanse of prairie grassland encompassing much of southeast Alberta, a swath of southern Saskatchewan, and the southwest corner of Manitoba. The area is named for explorer Capt. John Palliser, who in 1857, famously declared the entire region a wasteland — so hot and arid that no crops would ever grow.
Residents, councillors concerned about climate in wake of flash floods
About 77 millimetres of rain fell on Ottawa in a matter of hours, according to Environment Canada. That's more than any other Aug. 10 on record, but surrounding regions saw even more, receiving between 80 and 110 millimetres. At the storm's peak, Hydro Ottawa reported 24,000 customers without power. Mycah Katz was practicing a drag performance in the basement lounge of his condo building when the power cut out.
Norway prepares for more evacuations as river levels keep rising
Authorities were on standby to evacuate more people in southeastern Norway on Friday, where huge amounts of water, littered with broken trees, debris and trash, thundered down the usually serene rivers after days of torrential rain. The level of water in swollen rivers and lakes continued to grow despite two days of dry but overcast weather, with houses abandoned in flooded areas, cars coated in mud and camping sites swamped.
Deluge of damage claims pouring in after flash floods cause sewage 'mayhem'
Ottawa restoration companies are inundated with calls from households beset by sewage backup from Thursday's flash floods, which caused "catastrophic" damage to some homes. Deven Raval, owner of PuroClean, called it "mayhem." He said his company normally deals with five or so calls per day. But this has been different. "My phone's going crazy," he said, as rings repeatedly interrupted an interview. He'd already fielded about 70 calls as of Friday morning. He said four of every five relate to sewage.
Nova Scotia wrestles with aftermath of devastating floods
Canada's East Coast province of Nova Scotia began cleaning up on Sunday after torrential rainfall caused devastating floods, while the search continued for four people including two children who went missing during the deluge. The storm, which started on Friday, in some places dumped more than 25 cm (10 inches) in just 24 hours - as much as normally falls in three months. CBC meteorologist Ryan Snoddon said it was the most rain to hit the provincial capital Halifax since Hurricane Beth in 1971.
River levels and rain forecasts at 'unprecedented' lows in most of B.C.
Parts of the province are seeing unprecedented lack or rainfall and low streamflow levels, according to the latest wildfire and drought update from the provincial government. A majority of sites in the province are measuring an extremely low percentile of their usual levels. "On the streamflow side of things, somewhere in the order of [a little less than] one-third of the stations across the province are at record-low flow," River Forecast Centre head Dave Campbell told reporters at a news conference Thursday.
