About this water

The upper Kootenay in the Rocky Mountain Trench is broad, clear cutthroat water — long riffles, gravel bars and good runs holding native westslope cutthroat and bull trout with some rainbows. Big enough to float and full of willing fish, it fishes as fine dry-fly and streamer water through summer and autumn once it drops into shape.

Under the surface

The upper Kootenay between Canal Flats and Wardner is a broad, clear mountain freestone of long riffles, gravel bars and good runs holding native westslope cutthroat and bull trout with some rainbows. Big, floatable water in the Rocky Mountain Trench, it offers fine dry-fly and streamer fishing in classic Kootenay scenery.

Wading: Strong current, big river volume, flashy in runoff

  • Limestone
  • Partly confined
  • Pool riffle
  • Large river
Conservation note

Native westslope cutthroat (Threatened, C&R) and bull trout (char, protected, C&R), with some rainbows. Whirling disease/didymo concerns — Clean-Drain-Dry.
