About Thompson River

Thompson River, in Montana, United States, is a river where current dictates almost everything. Rocks, undercut banks, and fallen timber are the obvious targets, but the productive water at Thompson River is often the seam between two current speeds — that's where fish wait for food to drift past. Match the size of your bait or lure to whatever insects, baitfish, or crayfish you can see in the water.

Fishing Techniques

  • For Brown trout

    When fishing streams, focus on seams and current breaks, where trout hold to ambush prey.

  • For Rainbow trout

    Vary your retrieve speed when using spinners to find what triggers a strike; sometimes a slow, steady retrieve works best, while other times a faster, erratic retrieve is more effective.

  • For Brook trout

    Fish upstream, casting into pools and runs, allowing your bait or lure to drift naturally with the current for best results.
