Westslope Cutthroat Trout Conservation Reintroduction to Cascade Creek

Parks Canada proposes to reintroduce the Threatened westslope cutthroat trout into the 9km long, restored Cascade Creek channel in Banff National Park. Since 2018, Parks Canada has completed physical restoration works on Cascade Creek in preparation for the reintroduction. Ready for the next phase, this proposal considers fish translocation from source populations and long-term monitoring to ensure a self sustaining population. Genetics and pathogen testing have been undertaken to select two suitable donor populations of pure westslope cutthroat trout from within the park. The translocation will be undertaken by collecting gametes (eggs and milt) from the donor populations and hatching them out via remote stream incubators directly into Cascade Creek. This will occur over a period of three years (2024 to 2026) to ensure a range of age classes in the reintroduced population. Monitoring will occur for a minimum of 5 years post-introduction to ensure a self-sustaining population is achieved.
