About this water

The Crowsnest is the dry-fly jewel of southern Alberta — clear, limestone-touched freestone water full of willing wild rainbows and cutthroat, with browns in the lower reaches. It's famous for its hatches and for fish that look up, fished from the bank through riffles, pockets and green pools. Best from late June once the snowmelt clears, through a long summer and into a golden autumn. Release the cutthroat — they're a threatened native.

Under the surface

The Crowsnest is southern Alberta's marquee dry-fly river — a clear, limestone-tinged freestone tumbling out of the Pass through riffles, pocket water and deep green pools. It holds strong wild rainbows and cutthroat with browns lower down, and it is famous for prolific hatches and willing surface fish. Roadside accessible and wadeable, it's one of the best dry-fly rivers in the country when it's in shape.
