The Kootenai River is holding steady in great fall form, and conditions are about as good as it gets right now, according to Linehan Outfitting’s October 6, 2026 report. Libby Dam has dropped releases to 4,000 cfs, and those flows are expected to hold through the end of the month and likely into November — which means excellent wading access up and down the river. Water temps below the dam are sitting around 55 degrees, and the fish are keyed in on midges, baetis, caddis, and terrestrials. Weather-wise, it’s classic autumn: chilly, foggy mornings giving way to sunny days in the 70s, with high pressure sticking around until a chance of rain moves in by the weekend. In short, the window to get out there is wide open.
On the tactic side, it’s still a single-dry-fly game, and the big bugs aren’t done yet — size 12 Chubbies, stimulators, and water walkers are consistently fooling fish and should stay in the rotation through month’s end. If they refuse the big stuff, dropping to a #16 purple or parachute Adams will keep you in business, and a perdigon dropper (especially Uke’s brown bug) is always a reliable trailer. There’s honestly little reason to nymph unless you’re dead set on reaching a deep bucket. If you’re chasing one quality fish instead of numbers, though, now’s the time to pull out the streamer rod and put in a couple hours of swinging — it’s that time of year when the meat sticks earn their keep. For the complete rundown, the full report from Linehan Outfitting dated October 6, 2026 is worth checking out, along with their shop for gear.
