Restoration of 40-Mile Creek
This is a joint project with Parks Canada to decommission 40-Mile Dam • The town’s former water supply reservoir on 40-Mile Creek acts as a barrier to aquatic habitat connectivity: fish can’t swim upstream or downstream • The 1946 dam is trapping sediment, adding a further barrier • Impacting two threatened trout species: Bull Throat and Cut Throat Trout • Using provincial government funding, the dam will be partially removed in Spring 2014 • No change to seasonal flows of creek downstream • In-stream work to occur during two-week fisheries window in May • You may hear crews at work
