What swims here
- Mountain whitefish
- Westslope cutthroat trout
- Bull trout
Westslope cutthroat trout. Threatened in Alberta. Genetically pure populations survive in only a handful of headwater streams, so check the current closures before you go.
Bull trout. Alberta provincial fish and a threatened species. Zero retention province-wide. No black spots on the dorsal fin: if it has none, put it back.
Before you go
Whirling disease. The Canadian Food Inspection Agency declared the Oldman River watershed infected on 1 May 2017.
- Clean, drain and dry your watercraft and any equipment that has been in contact with water, completely, between trips.
- Never move live or dead fish or fish parts from one waterbody to another. This is illegal in Alberta, and so is using live fish as bait.
