Discover How Climate Change is Affecting Local Watersheds: Key Insights from Recent Data – My East Kootenay Now

Hot, dry summers are becoming the norm in the Columbia Basin. Living Lakes Canada (LLC) is calling for better water management that meets local needs.

The Columbia Basin Water Monitoring Framework (CBWMF) Network tracks 118 sites, covering small watersheds like streams, lakes, wetlands, and even snow depth. Recent findings show how climate change is affecting these watersheds, particularly in the West Kootenay region.

Dr. Martin Carver, a consulting geoscientist, notes that these smaller watersheds serve as early indicators of water reliability. “They help us see changes that can impact community resilience and ecosystem health,” he explains.

The latest focus is on north-facing watersheds, such as Bjerkness, Harrop, Kootenay Joe, and Carlyle. Arlo Bryn-Thorn, the CBWMF program manager, emphasizes their importance for future water supplies. “These areas melt later in spring, providing a longer flow during summer droughts,” he says.

However, not all areas are holding up well. Bryn-Thorn observes some signs of stress from climate change, while others remain stable. “These insights help identify drought risks and shape better water management strategies,” he adds.

Unlike in the past, when snowpack levels provided steady water supplies into summer, current trends show a decline due to rising temperatures and earlier springs. Bryn-Thorn points out that with less summer rain and extended heat waves, late summer water supplies are dwindling.

“Water flows are lower because spring warmth is arriving sooner and summer rainfall is decreasing,” he cautions. “This is leading to longer periods of low water supply in certain areas.”

To tackle these challenges, Bryn-Thorn advocates for more data and research. He believes this will guide decision-making at all levels of government about water conservation.

According to a recent study by the Canadian Water Resources Association, nearly 60% of Canadians worry about water shortages due to climate change. This reflects a growing awareness of the severity of water issues across the country.

Climate experts urge communities to adapt, emphasizing the need for tailored solutions. “Understanding how different watersheds are responding uniquely to drought is crucial,” Bryn-Thorn concludes.

As local conditions shift, it is clear that smart water management will be vital for sustainable living in the Columbia Basin.
