About this water

The Bull River is a clear, muscular Kootenay cutthroat freestone east of Cranbrook — pools, pockets and canyon water holding native westslope cutthroat and bull trout in dramatic country. Partly hydro-regulated upstream, it fishes well for summer and autumn cutthroat on the dry once it's in shape. A fine, sensitive native river.

Under the surface

The Bull River east of Cranbrook is a clear, powerful Kootenay freestone of pools, pocket water and canyon reaches holding native westslope cutthroat and bull trout. Partly regulated by an upstream hydro facility, it offers strong summer and autumn cutthroat fishing in dramatic mountain country and, like its neighbours, is a sensitive native fishery.

Wading: Swift cold water, canyon sections, flows affected by upstream regulation
