The Water Security Agency is preparing to release significant water volumes from Lake Diefenbaker into the South Saskatchewan River, anticipating a rise in water levels by approximately 0.6 metres in Saskatoon. This surge poses challenges for local groups, including the Saskatoon Racing Canoe Club, which must adapt to the swift currents and altered conditions.
Rapid Changes in Water Levels
The influx of water originates from Alberta, where record snowpack levels have been reported, with some areas exceeding three metres—unprecedented figures for many in the region. Following a rapid melt last week, compounded by over 100 millimetres of rain in just a few days, the water is now flowing towards Saskatoon.
Rob Sleeth, coach of the Saskatoon Racing Canoe Club, expressed concerns about the immediate impact on their operations. “We have schools that come down and do dragon boating, so we’ve had to cancel those. For our athletes who train twice a day, it will present a challenge. We might have to relocate our training to a pond in Stonebridge or perhaps out to Pike Lake,” he explained.
Historical Context and Current Risks
John Pomeroy, a professor at the University of Saskatchewan and director of Global Water Futures Observatories, highlighted that current water levels are nearing those recorded during significant events in 2011 and 2013. He noted, “We haven’t seen water levels this high in over a decade. While flooding is unlikely, the situation can still be perilous.”
The swift flow of the river is a concern. “The river’s going to be flowing much more quickly than we have experienced recently,” Pomeroy cautioned. “The banks are dangerous, they can erode easily, and the river water is cold and fast-moving. It’s crucial for people to avoid swimming in the river and exercise extreme caution when canoeing or kayaking, especially near the weir.”
In response to the potential hazards, the Saskatoon Fire Department has advised residents and their pets to stay clear of the water.
Environmental Benefits Amidst Challenges
Despite the challenges posed by the increased water levels, there are environmental advantages that could arise. Pomeroy remarked, “This brings the river closer back to its natural system. It should help flush and redistribute some of the sand within the Saskatoon area.” The restoration of the river’s natural flow is seen as beneficial for local ecosystems and navigation.
Mike Steckhan, senior captain of Prairie River Cruises, welcomed the upcoming changes. “It keeps the river entirely navigable and safe for everyone. I’m looking forward to the river reverting to its former state,” he stated, underscoring the potential for improved conditions for local river tourism.
Why it Matters
The decision to release water from Lake Diefenbaker not only highlights the delicate balance between managing resources and addressing environmental concerns but also underscores the need for communities to adapt to changing conditions. While the immediate implications may disrupt local activities, the long-term benefits could enhance the ecological health of the South Saskatchewan River, promoting biodiversity and recreational opportunities. Understanding these dynamics is crucial for fostering resilience in our communities, particularly in the face of climate variability and the challenges it presents.
