Bitterroot River Fishing Report: June 5, 2026

Overview: Last week's rain-on-heat event blew out every river in the Missoula area; all four are now dropping and trending the right way. Rock Creek is the clear play (Grizzly Hackle has it at a 5/5 with the salmonfly hatch in full swing), the Bitterroot has the best clarity of the big rivers, the Blackfoot is waiting on its salmonflies, and the Clark Fork is, as usual, the last to clear. Best window: 10:30 a.m. – 3:30 p.m. (Lightweight, 5/31). Weather: sunny and warm today, rain moving in Sunday (NWS, 6/5).

At a glance: High but fishing well, clarity improving (Grizzly Hackle calls it great) · Darby ~3,620 / Bell Crossing ~7,950 / Missoula ~11,000 CFS, dropping fast · 47–59°F · Grizzly Hackle: 3/5 · MAngler: 3/5 · Best window: 10:30 a.m. – 3:30 p.m.

Floaters beware: log jams and debris are a major hazard. Lots of trees are down again this year and a few places are dangerous. With the water dropping fast, wood on the banks is moving around and potentially creating new jams (Blackfoot River Outfitters, Kingfisher, and Missoulian Angler all flag this). Know your stretch before you launch and float cautiously.

The Bitterroot had a huge bump over the last five days and is now dropping fast, and it has fished well for those braving the flows. The river is high but clarity is good and the fish are hungry. The upper river around Darby is the most manageable; the middle and lower river still carry heavy water. Salmonflies are starting to show on the upper river and West Fork, and PMDs are showing consistently in spots. Lightweight rates the Bitterroot system the best overall regional odds this week. Fish the soft inside bends, side channels, and pools; leave the fast water to the floaters.

Best techniques:

• Worms first. The good ol' worm has proven most effective: Worminator, Squirm, Jig SJ, Wire Worms. Big stonefly nymphs are a strong second: TB Pat's (#6-8), TJ Hooker Stone (#6-8), DB Stones, Jigglers, and Front St. Stones. Nymph heavy and deep.
• Mayfly and caddis droppers if you find a hatch: Jig PT, TNT PMD, Blowtorch, Duracell, Shuck It, Hares Ear, Frenchies (#14-16), and perdigon-style nymphs (#14-18).
• Streamers can be great right now, and you can get away with a big one: Articulated Sparkle Yummies, Bangtails, Shake and Bakes, an Olive Dungeon, a Yellow Peanut Envy, plus Mini Dungeons, Sparkle Minnows, Thin Mints, Sculpzillas, and black Woolly Buggers tight to banks and structure.
• Dries in the soft afternoon windows: BWO Comparaduns (#16-18), March Browns (#12-14), Elk Hair Caddis (#14-16), and foam stoneflies (#6-10). Blackfoot River Outfitters' dry box adds Jake's Hi-Vis CDC Caddis, MFC Royal Wulff, Plan B (Black/UV Black and Black/Purple), Carlson's Purple Haze, and MFC Hot Spot Para-Wulff (Brindle).

Hatches: PMDs consistent in spots, caddis here and there, BWOs and March Browns in soft water, salmonflies building on the upper river. Goldenstones, the salmonfly's little brother, are right around the corner and often make for excellent dry fly fishing while everyone else chases the salmonfly madness. Green Drake and Yellow Sally activity comes next as flows stabilize.

Outlook: Expect the Root to fish much better on top over the next couple of weeks. The main stem should see decent numbers of golden stones, and the upper river already has salmonflies with more on the way. Warm today, rain Sunday, improving as flows drop.
