Hellroaring Creek

Hellroaring Creek is a tributary creek flowing into St. Mary River. Recorded fish: Burbot, Westslope (Yellowstone) Cutthroat Trout.

The water

It flows into St. Mary River within the St. Mary River watershed (St. Mary River → Kootenay River). It runs stream order 5 (well down the network, toward river scale; the scale runs from 1 for a headwater trickle to 6+ for a river) and roughly 28 km. Burbot, Westslope (Yellowstone) Cutthroat Trout, recorded here in provincial fish-inventory data (9 records). The fish-passage model expects Bull Trout here too, since the reach is reachable with no barrier between, though there is no direct record yet. Named tributaries: Angus Creek.

The fishing

As a small stream, a tributary of St. Mary River, Hellroaring Creek fishes the way creeks of its size do: short drifts with a buoyant attractor dry over a light dropper, working the pocket water and the heads of pools. Match the fly box to the season and confirm against a current local report.
