Flathead River Fishing Report | July 7, 2025

Report by Ryan Stultz, Bent Fly Fishing
Ryan Stultz runs Bent Fly Fishing and guides the main stem of the Flathead River and nearby Montana rivers.
What is working right now

Dry-fly fishing on the main stem of the Flathead River is exceptional in early July 2025. Ryan Stultz of Bent Fly Fishing had a guide net 40 fish in a day on a foam bug fished up top, with bright orange-bellied native westslope cutthroat rising to big dries. The nearby Clark Fork is chugging dry flies in the morning shade, then droppers like Pat's Rubber Legs when the sun rises. On the Blackfoot, salmonflies are dwindling but a big Water Walker still produces.

How is the Flathead River dry-fly fishing?

Exceptional right now, which Ryan Stultz says he does not get to claim often. A guide who fishes for him netted 40 fish in a day on dry flies, throwing a foam bug up top. The fish are looking up, and native westslope cutthroat are rising well to big dries.

What fly is working on the Flathead?

A foam bug fished on top. Ryan's guide uses a homebrew foam pattern, but you do not need the exact bug. Plenty of fish are looking up and will eat a big dry. Expect bright orange-bellied native westslope cutthroat to rise to it.

How is the Clark Fork River fishing?

Still exceptional. When shade is on the water in the morning, the dry fly gets chugged. As the sun climbs, switch to a dropper. San Juans, Pat's Rubber Legs, and Pheasant Tail jigs are all producing, with Pat's Rubber Legs the go-to as nocturnal stoneflies appear.

How is the Blackfoot River fishing?

Recently good on salmonflies, though the hatch is dwindling and turning hit or miss. Ryan floated the canyon and hit it right, throwing a big Water Walker up top and cutting the dropper off entirely for a few hours while the fish chugged dries during peak feeding.

What is the summer dry-fly plan?

Lead with dry flies early, especially in morning shade on the rivers. Add a dropper like Pat's Rubber Legs or a Pheasant Tail jig once the sun is high. On the Blackfoot, fish a big topwater Water Walker and skip the dropper when salmonflies are active.

What is the outlook for early July?

Strong. Ryan calls it a great week with everything still looking good at the beginning of July across the Flathead, Clark Fork, and Blackfoot. Get out and enjoy the dry-fly window. Exact water temperatures were not specified in this report.

Watch the full report

From the report (Ryan Stultz, Bent Fly Fishing): Our local, the main stem of the Flathead River, is fishing exceptional. He said they netted 40 fish on dry flies, throwing a foam bug up top. There's not much better than watching a bright orange belly native Westslope cutthroat rise to a big dry fly. The Clark Fork River is still fishing exceptional, and the Blackfoot had lots of salmonflies flying around.
