A recent evaluation of Wasa Lake is sparking concerns regarding the capacity for powerboating activities on the small East Kootenay lake. The initial assessment of water and sediment quality, conducted by Larratt Aquatic Consulting for the Wasa Lake Land Improvement District, indicates that while the water quality is suitable for recreational purposes based on limited 2025 sampling, there are significant petroleum-based hydrocarbon contaminants in the sediment.
Wasa Lake, situated within Wasa Lake Provincial Park around 30 kilometers north of Cranbrook, covers an area exceeding one square kilometer. The report reveals that powerboating in shallow areas can disturb sediment at the lake bottom, raising environmental issues.
This discovery has sparked a wider discussion on boating, water conditions, and the need for potential restrictions at Wasa Lake. The report categorizes Wasa Lake as a “high-risk” location for powerboating based on a lake suitability index, indicating that only a small portion of the lake meets the depth and distance criteria for powerboating. The report estimates that the lake can safely accommodate two powerboats or wake-surfing boats simultaneously, considering water quality and ecological factors.
The divisive nature of this topic has been evident among the local community surrounding Wasa Lake for some time. The Wasa Lake Stewardship Volunteers, a local group focusing on the lake’s well-being, emphasize that the lake’s shallow and enclosed nature, with limited water circulation, can lead to the accumulation of pollutants and disturbances compared to larger, flowing water bodies.
Shauna Mabey, a dedicated volunteer in the area, stresses that the concern is not to eliminate motorboats entirely but to address the resuspension of chemicals from the lake bottom caused by larger boats. Suggestions for potential measures include speed restrictions, limits on boat size, or other regulatory actions. The Regional District of East Kootenay board has recently requested Transport Canada to establish science-based guidelines to determine when powerboat activities may endanger the lake’s health, aiming for standardized criteria on the issue.
Kimberley Mayor and RDEK Director Don McCormick highlights the necessity of Transport Canada’s cooperation for any future initiatives, emphasizing the importance of their support for progress. Mabey expresses apprehension about the consequences of inaction, fearing irreversible damage to the lake if no changes are implemented, envisioning a future where regrets may arise due to a deteriorating environment.
