Westslope Cutthroat Trout

Westslope Cutthroat Trout (Oncorhynchus clarkii lewisi)

Key points

  • Range: East Kootenays are primarily cutthroat fisheries (West Kootenays skew rainbow) .
  • Behaviour: free-rising; a bit of sparkle/shine brings them to the surface .
  • Selectivity: during blanket hatches they focus on specific patterns — match the hatch .
  • Where: Goat River, feeder creeks (Sanca, Kidd, Summit, Meadow), alpine lakes like Wooden Shoe Lake (Trailhead) and Boundary. Within a day's drive, Fernie's Elk River is world-renowned for big topwater "cutties" .
  • Neighbours: shares East Kootenay water with rainbow, bull trout, brook char, kokanee, Rocky Mountain whitefish and bass .
  • Flies: Royal Wulff, Chubby Chernobyl, and other attractor dries; nymphs like the Copper John and Pat's Rubber Legs when feeding subsurface.

Regulations (Region 4, 2025–2027)
