6/15/2026: Bitterroot River Fishing Report
Summary
Early summer has arrived and all four rivers keep dropping into shape. The story across the region is a hand-off: the salmonfly hatch is winding down and pushing into the upper drainages, while golden stones take over as the headline big bug river-wide. Green Drakes, PMDs, yellow sallies, and caddis are all filling in, so this is prime dry-dropper season. The Blackfoot and Rock Creek are the standouts (Grizzly Hackle rates both 5/5), the Bitterroot offers the best all-around odds, and the Clark Fork has turned the corner and is fishing well as clarity improves. Best regional window this week runs roughly 9:30 a.m. to 2:30 p.m. (Lightweight), and warm afternoons mean watching water temps and starting earlier when needed. Float anglers: fresh down trees and log jams are a real hazard on the Bitterroot and Rock Creek as flows drop fast, and Rock Creek is getting skinny for floating.
At a glance: Dropping and in good shape with improving clarity, mid-day water temp around 56°F | GH 3/5 | Missoulian Angler 4/5 | Best window 9:30 a.m. to 2:30 p.m.
Dropping and in good shape with improving clarity, mid-day water temp around 56°F. Roughly 3,950 CFS near Missoula, dropping to about 1,480 near Darby. The upper and middle river are much more manageable and the lower river is starting to fish better too. The West Fork is the cleanest smaller-water option and is fishing well with salmonflies.
Note. Lots of trees are down again this year and a few spots are dangerous. Log jams and debris are a major hazard, and the danger increases as the water drops fast. Floaters need to stay alert and float cautiously.
Best techniques
Most action is subsurface, with dry fly fishing improving each afternoon. Nymph a Pat's Rubber Legs, DB Stone, TJ Hooker, Jiggler, San Juan Worm, Duracells, or Blowtorches through softer water. Dry-dropper fishing is consistent, with some fish rising to the big dry on the lower river: reach for a Dancin' Ricky, Fool's Gold, Water Walker, or Chubby Chernobyl up top. For the mayfly windows, cover yourself with Brindlechutes, Purple Hazes, Hatchback Drakes, Carnage Drakes, and Ms. Tickles. Streamer fishing can be great right now, and you can get away with a big articulated streamer this time of year.
Hatches
Salmonflies are active in the upper system, while Golden Stones become more important each day. PMDs, Green Drakes, Yellow Sallies, and caddis are all in the mix, with BWOs on the West Fork.

Outlook. Temps in the 60s and 70s over the weekend, reaching the upper 70s and 80s through the week. Golden stones are right around the corner on the mainstem, and salmonflies on the horizon there too. Fishing should keep improving as runoff fades and insect activity builds throughout the valley.
