As moving water, a tributary of Kootenay River, Simpson 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 Simpson 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.
