West Fork Bitterroot Fishing Report – March 7, 2025
Current Conditions:
The West Fork of the Bitterroot is running clear with moderate flows, thanks to recent cold nights. Water temperatures are in the mid-30s, and fish are holding in slower, deeper pools. Weather patterns have been variable, with daytime highs in the mid-40s and occasional snow flurries.
Hatches & Fly Recommendations:
- Midges are still the primary hatch, with fish keying in on small dries and emergers during the warmest part of the day. Try a Griffith’s Gnat (#18-22) or a Smoke Jumper (#20-22).
- Skwala stoneflies are starting to get active, and trout are beginning to notice them. A Pat’s Rubber Legs (#8-10, olive or brown) works well as a nymph, while a Chubby Chernobyl (#10-12, olive/tan) may get some early looks on the surface.
- Nymphing remains the most productive approach. Zebra Midges (#18-20, black/red), Pheasant Tails (#16-18), and Rainbow Warriors (#16-20) fished under an indicator or Euro-nymphed are great bets.
- Streamer fishing is improving, especially on cloudy days. Slowly stripping a Mini Dungeon (olive or black, #6-8) or a Sparkle Minnow (#6-8, pearl or sculpin) along structure can move big fish.
Best Techniques:
- Nymphing deep is the most consistent way to find fish. Use enough weight to get down to the bottom in deeper runs.
- Look for rising fish in slower tailouts during the warmest part of the day when midges are coming off.
- Streamer fishing can be effective early and late in the day, particularly in deeper pools and along cut banks.
Access & River Conditions:
Flows are stable, but be cautious of ice along the banks, especially in shaded areas. The West Fork Road is passable, but expect some snow and ice in the mornings. If you’re floating, keep an eye out for downed trees from winter storms.
Outlook:
With warming temperatures, Skwala activity will pick up over the next couple of weeks, bringing some of the best early-season dry fly fishing in Montana. Keep an eye on water temps—once they push into the 40s consistently, the dry fly bite will turn on.
