The Water Security Agency has announced plans to release water from Lake Diefenbaker into the South Saskatchewan River, resulting in a significant increase in water levels in Saskatoon by approximately 0.6 metres. This surge in flow has immediate implications for local activities, particularly affecting the Saskatoon Racing Canoe Club and its training programmes.
Impact on Local Water Activities
As the river swells, the Saskatoon Racing Canoe Club faces considerable adjustments to their operations. Coach Rob Sleeth lamented the disruption: “We have schools that come down and do dragon boating, so we’ve had to cancel those. And then for our athletes who train twice a day, it will be a challenge. We’ll have to go elsewhere, maybe to some pond in Stonebridge or perhaps out to Pike Lake to continue training.” The club’s commitment to nurturing local talent is now hindered by the unpredictability of the river’s conditions.
The influx of water is a result of an unprecedented snowpack in Alberta, which has exceeded three metres in some regions, leading to rapid melting. Following an intense rainfall of over 100 mm within a matter of days, this water is now making its way downstream.
Historical Context of Water Levels
John Pomeroy, a professor at the University of Saskatchewan and director of Global Water Futures Observatories, highlighted the significance of the current situation. “We’re getting to levels that were seen in 2013 and 2011. Those two stand out very much,” he noted. He added that these levels have not been observed for over a decade. While the risk of flooding remains minimal, Pomeroy cautioned that the fast-flowing river presents new dangers. “The river’s going to be flowing much more quickly than recent experience has lent us, and so it’s dangerous. The banks are at risk of erosion, the water is cold, and it’s very, very fast,” he advised.
Pomeroy also urged caution, especially for those engaging in recreational activities. “I think it’s important for people not to swim in the river. And if they’re canoeing or kayaking, they need to be very careful and stay away from the weir as always.”
Safety Measures and Environmental Benefits
In response to the changing conditions, the Saskatoon Fire Department has also issued warnings for residents and their pets to avoid the water. However, amidst the challenges posed by rising water levels, there are potential ecological advantages. Pomeroy remarked, “This brings the river closer back to its natural system. It should flush and move some of the sand to the system that we see in Saskatoon.”
This natural sedimentation process may enhance the river’s ecosystem, promoting a healthier environment. Mike Steckhan, senior captain of Prairie River Cruises, expressed optimism regarding the river’s restoration: “It keeps the river entirely navigable and safe for everybody. So, I’m looking forward to the river turning itself back into what it used to be.”
Why it Matters
The release of water from Lake Diefenbaker highlights the delicate balance between human activities and natural water systems in Western Canada. While the immediate disruptions to local sports and leisure activities are evident, the potential for ecological rejuvenation presents a silver lining. As communities adapt to these changes, the emphasis on responsible engagement with the river becomes paramount, ensuring both safety and sustainability for future generations.
