About this water

Once the most famous steelhead river on earth — the Thompson's big interior fish rising to a skated dry in the cold November canyon defined a whole school of fly fishing. That history is now history: Interior Fraser steelhead have crashed to a remnant population, they're assessed Endangered, and the recreational fishery has been closed. This is a river to honour, not one to plan a trip to. It stands here as a record of what the Thompson was and what it may yet become — should the run recover and the fishery reopen.

Under the surface

The Thompson was, for a generation, the most revered steelhead river in the world — huge interior fish that ate a skated dry in November in a desert canyon. It is included here as a place to honour and, for now, to leave alone: Interior Fraser steelhead (Thompson and Chilcotin) have collapsed to a few hundred fish, are assessed Endangered, and the recreational steelhead fishery has been closed. We carry it as a conservation record, not a fishing recommendation.

Conservation note

Interior Fraser steelhead are Endangered (COSEWIC) and the recreational fishery is closed. This venue exists to inform and honour the river, not to direct anglers to it. We never score a closed, endangered population as a fishing opportunity.
