Hoot Owl Restrictions are in place on the Main Stem of the Bitterroot River. No fishing between 2pm - Midnight!
East and West Fork are NOT under any restrictions.
Summer is in full swing on the Bitterroot River, and fishing continues to be productive for anglers willing to get an early start. Water levels are ideal for both floating and wade fishing, and trout are feeding aggressively during the cool morning hours and again in the evening. Midday fishing can slow as water temperatures rise, so we recommend carrying a thermometer and giving the fish a break if temperatures reach 68°F or higher.
River Conditions
The Bitterroot is running clear with excellent visibility. Fish are holding in oxygen-rich riffles, deeper runs, undercut banks, and shaded structure. The upper river around Darby and the East and West Forks continue to offer the coolest water temperatures and the most consistent fishing throughout the day.
Dry Fly Fishing
Dry fly fishing has been the highlight of the week. Terrestrial season is beginning to take off, and trout are looking up for hoppers, ants, and beetles along grassy banks. Caddis continue to hatch during the evenings, providing excellent opportunities right before dark.
Top Dry Flies
- Morrish Hopper #8–10
- Thunder Thigh Hopper #8–10

Nymph Fishing
When trout aren't rising, nymphing remains productive in deeper runs and faster pocket water.

- Frenchie #14–18
- Perdigon #16–18
- Pat's Rubber Legs #8–10
- Lightning Bug #16–18

Best Time to Fish
- Early Morning: Outstanding dry fly and nymph fishing.
- Late Morning: Fish riffles and deeper seams before the heat sets in.
Guide's Tip
Fish tight to grassy banks and under overhanging willows with hopper patterns. Many of the Bitterroot's larger trout are beginning to key in on terrestrials, and accurate casts within a few inches of the bank can make all the difference. If fish refuse the hopper, trail a small Pheasant Tail or Perdigon 18–24 inches below it.
Looking Ahead
With stable summer conditions and hopper season just getting started, the next several weeks should provide some of the best dry fly fishing of the year. Early starts, careful fish handling, and attention to water temperatures will help ensure excellent fishing while protecting the Bitterroot's wild trout population.
