About this water

The Sheep is intimate Highwood-system freestone west of Turner Valley, clear and cold through riffles, pools and little canyons, holding native cutthroat and bull trout with some rainbows. It opens in mid-June after the spawning closure and fishes as pretty dry-fly water into October. Strict native-trout rules apply — fish it lightly.

Under the surface

The Sheep is a Highwood-system foothills freestone west of Turner Valley — clear, cold, intimate water of riffles, pools and small canyons holding native westslope cutthroat and bull trout with some rainbows. Like its neighbours it carries a spawning closure into mid-June and strict native-trout rules; once open it's pretty dry-fly fishing in close foothills country.

Wading: Swift cold water, flashy after storms
