The Clark Fork River experienced improved fishing conditions post-Labor Day, with flows around 1,200 cfs. Cooler waters have made trout more active, encouraging anglers to use smaller dries and various nymphs. The segment from Weigh Station to Sha-Ron is closed until October 31st, as fall fishing strategies begin to evolve.

September fishing is thriving across various locations, with walleye, rainbow trout, and kokanee actively biting. Key spots include Canyon Ferry, Hauser, and Holter. Techniques vary from trolling to jigging with specific baits. The kokanee salmon snagging season is also open, allowing anglers to catch larger fish.

The Upper Madison River offers excellent fishing conditions as summer fades, according to a September 4, 2026 report by Big Sky Angler. Midday fishing is optimal, with an emphasis on terrestrials like hoppers and ants. The report suggests effective techniques and highlights the importance of adjusting fly selections as temperatures cool.

Holter’s kokanee are proving elusive, with varying success among anglers. Currently, trolling at depths of 60' to 90' yields fish averaging 2-5 pounds, using dodgers and squid or wedding rings. Walleye are also active, favoring drop-offs and responding well to jerk baits. Perch catches remain inconsistent.

The Bighorn River in Montana is experiencing optimal tailwater conditions with steady flows of 1,000–1,500 cfs and clear water below Yellowtail Dam.

Montana Angler in Bozeman advises anglers on fishing smaller waters while complying with stream access laws. To maximize success in late June and July, use simple flashy attractor dry flies. As streams become low and clear in August, a stealthy approach will be necessary to avoid spooking fish. Happy fishing!

The Bitterroot River's conditions are challenging yet promising for anglers, offering good opportunities for both dry-fly and nymph fishing, especially in upper sections, amid fluctuating water clarity and summer hatches.

To escape Bozeman's chill, fish the Bighorn River from 11 AM to 4 PM using nymphing techniques. A BWO hatch is approaching, so focus on slow water and effective flies.
