Flathead River Fishing Report | July 7, 2025

Report by Ryan Stultz
Ryan Stultz guides for Bent Fly Fishing on the rivers of northwest Montana.
What is working right now

Dry-fly fishing on the Flathead River is exceptional in early July 2025. Guides netted up to 40 fish in a day on foam bugs fished on top. Native westslope cutthroat are looking up. The Clark Fork is strong on morning dries then droppers, and the Blackfoot salmonfly hatch is dwindling but still worth a big topwater pattern.

What is biting on the Flathead River right now?

Native westslope cutthroat trout are the target and they are looking up. A guide netted 40 fish in a day on dry flies, throwing foam bugs on top. Early July surface action on the main stem of the Flathead is as good as it gets, with bright orange-bellied cutthroat rising to big dries.

What flies are working on the Flathead in July?

Foam bugs fished on top are producing on the Flathead. On the Clark Fork, fish morning dries then switch to droppers as the sun rises, using San Juans, Pat's Rubber Legs, and Pheasant Tail jigs. On the Blackfoot, a Water Walker draws salmonfly-era topwater eats. Exact patterns beyond these were not specified in this report.

How is the Clark Fork River fishing?

The Clark Fork is fishing exceptionally well. Warm spells balanced by cool-downs have held water temps in good shape. When shade is on the water in the morning the dry fly gets chugged, then the dropper takes over as the sun climbs. Pat's Rubber Legs is a go-to, with nocturnal stones making an appearance.

Is the Blackfoot salmonfly hatch still on?

The Blackfoot salmonfly hatch is dwindling and turning hit or miss. On a good day you can throw a big Water Walker on top and cut the dropper off entirely during peak feeding. Timing is everything now, so target windows when salmonflies are active rather than counting on all-day action.

What is the guide's outlook for early July?

Ryan Stultz reports everything still looking good at the beginning of July, with strong surface activity across the Flathead, Clark Fork, and Blackfoot. He expects the dry-fly window to hold. Specific flow numbers and water temperatures were not specified in this report.
