After an extensive eight-year pursuit for funding, Kimberley City has successfully secured $400,000 to conduct a study on the potential impact of wildfires on its drinking water supply. This initiative stemmed from concerns raised during the 2018 Meachen Creek fire, highlighting the vulnerability of local water sources.
Mathieu Bourbonnais, an assistant professor at the University of British Columbia (UBC) Okanagan and co-director of the Centre for Wildfire Coexistence, emphasized the importance of acknowledging the reliance on the environment for drinking water. He noted that wildfires are altering the behavior of natural systems that provide this essential resource.
Kimberley draws its drinking water from the Mark Creek and Matthew Creek watersheds. The project’s objective is to identify risks associated with wildfires and develop strategies to mitigate these risks without compromising the water supply’s integrity.
The recent Matthew Creek wildfire, which prompted an evacuation alert for the entire city, brought attention to the potential threats faced by Kimberley’s watersheds. While wildland fire ecologist Bob Gray indicated that the recent fire’s impact on water movement in the watershed is expected to be minimal, the concern remains for larger, more severe fires affecting the drinking-water sources.
Severe wildfires have the potential to disrupt vegetation, soil, erosion, sedimentation, and snow accumulation patterns, ultimately altering water quality and flow dynamics. Collaborative efforts between UBC Okanagan, the city, and Gray aim to model potential fire behavior in the Mark Creek watershed up to 2060, considering forest conditions, climate projections, and water quality impacts.
By evaluating where forest thinning, harvesting, and prescribed burning can reduce wildfire risks, the research will provide valuable insights for future mitigation efforts. The project, funded by the Columbia Basin Trust and the city, is anticipated to span two years and aims to offer guidance for wildfire mitigation strategies to safeguard drinking water supplies in Kimberley and potentially other communities.
The importance of proactive measures in mitigating wildfire risks was underscored, emphasizing the significance of planning for the future to avoid potential environmental consequences.
