It flows into kootenay 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 33 km. bull trout, kokanee, Westslope (Yellowstone) Cutthroat Trout, recorded here in provincial fish-inventory data (8 records).

As moving water, a tributary of Kootenay River, Wild Horse River fishes the way rivers of its size do: read the runs and seams, fish a dry-dropper through the warm months, and swing streamers or nymph the deeper slots as flows drop. Match the fly box to the season and confirm against a current local report.

Access for Wild Horse River, meaning the roads in, put-ins and any walk-in or seasonal limits, is worth confirming locally before you commit a day. The drainage map shows how the water sits in its valley.
