Blackfoot River Outfitters's Tip of the Week

The Bitterroot is taking its summer fishing shape. Riffle edges, tailouts, grassy banks, and soft bank seams are absolutely loaded with feeding fish. The trout are seeing a variety of bugs, making them active and willing to eat dry flies. 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! Fishing in the morning and the evenings will be the best time to be on the water. Keep an eye on water temps in the afternoons as it is starting to get hotter.

5-Day Outlook as of 7/10/26

The Bitterroot valley will be hot this weekend with temps in the 80s and 90s. Next week temps look to be in the 80s with a mix of clouds and sunshine throughout the whole week.

Techniques & Tips as of 7/10/26

A dry-dropper rig is the best option to cover water. Throw a Chubby Chernobyl or Water Walker and then drop a PMD nymph or a general attractor nymph like a Blowtorch, Duracell, or Frenchie 18 to 24 inches below the dry. As the hatches of PMDs and Caddis happen throughout the entire day look for rising fish and switch over to a single dry. A Purple Haze, Hot Spot Para-Wulff, a PMD spinner or a small Elk Hair Caddis are great options to catch those rising fish.

Local Species Available Year round; some tributaries closed December 1-third week of May. Check regulations before fishing.

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.
