Blakiston Creek is a cold, clear headwater tributary flowing through Waterton Lakes National Park in southwestern Alberta, Canada. Situated at elevations ranging from approximately 1,333 to 1,478 metres above sea level, this mountain stream drains rugged terrain within one of Canada's most scenic national parks, where the Rocky Mountains meet the prairies. The creek is recognized as one of the most productive bull trout streams in the entire Waterton River watershed, making it a significant fishery from both a conservation and angling perspective. Its cold, high-quality thermal habitat is precisely what makes it such an important refuge for native char species. It is worth noting that current regulations designate Blakiston Creek and its tributaries as closed waters, meaning the creek is presently off-limits to angling as part of ongoing bull trout recovery efforts — anglers should always verify the most current Parks Canada regulations before planning any trip.
