Blackfoot River Outfitters's Tip of the Week

The Bitterroot had a huge bump the last 5 days. Fishing will be tough but definitely doable. Salmonflies are starting to show up on the upper river so have your big bugs ready. Log jams and debris are still a major hazard especially with the watering dropping as fast as it is, so floaters need to stay alert. Float cautiously! With the rivers bumping up, remember the creeks and stillwaters are open, and could be a good spot while the rivers are running high.

5-Day Outlook as of 5/29/26

The Bitterroot will be cool and rainy over the weekend with highs in the 50s. Tuesday is the day we turn the corner and get highs back into the 70s.

Techniques & Tips as of 5/29/26

Nymphing or dry-dopper rigs are the best way to move fish on the Root right now. Stick to larger profile nymphs like stoneflies or San Juan worms until clarity improves. Streamer will also be effective with the bump in the water. A Olive Dungeon, Sculpin Articulated Sparkle Yummy and a Yellow Peanut Envy.

Description: About Bitterroot River

The panoramic mountains of the Selway-Bitterroot Wilderness towering above this river make for an unforgettable setting. The Bitterroot affords anglers over 80 miles of varied freestone trout water ranging from riffles and runs to undercuts and deadfalls. This river's largest fish often rise to dry flies even in non-hatch conditions. One of our guides claims that "If you catch a fish on the Bitterroot, you could have caught it with a dry fly!" This probably isn't far from the truth in light of our fishing dries here 90% of the time (often with an additional bead head dropper). Renowned hatches of stone and may flies are in full force by March, providing the state's best early season surface action and Bitterroot river fish tend to look up for the rest of the season. Expect to catch native westslope cutthroat, rainbows and browns on any outing.
