West Fork of the Bitterroot Fishing Report
The West Fork is offering some great fall fishing opportunities. With cooler flows and crystal-clear water, trout are holding in a mix of pocket water and deeper pools. This section has been fishing particularly well in the afternoons.
Dry Fly Action
-
Hoppers are still bringing fish up, especially around grassy edges and mid-river rocks.
-
Mahoganies are consistent and will only get better in the coming weeks.
-
Parachute adams and small BWOs are dependable on cloudy afternoons.
Nymphing & Streamers
-
Perdigons, copper johns, and small prince nymphs are working well when fish aren’t looking up.
-
Streamer fishing has picked up—try olive or black sculpins fished through logjams or undercut banks.
-
A hopper-dropper setup with a size 14 mayfly nymph underneath is producing steady action.
Fishing Strategy
-
Focus on shaded banks in the afternoon when fish slide into softer water.
-
Early mornings can be slow, but by mid-day the action picks up and carries through evening.
-
Cover pocket water thoroughly—fish are holding tight to structure.
Guide’s Note: The West Fork is fishing better each day as we move deeper into September. It’s a great choice for anglers looking for solitude, technical dry fly eats, and some streamer opportunities.
