Report by Capt. Ryan Stultz
Ryan Stultz runs Bent Fly Fishing in Montana and reports for Catch America.
What is working right now

The Flathead River is fishing great, especially midday and late afternoon, with an exceptional dry-fly bite and lots of active fish. When wade fishing, work in from the inside edges and seams rather than casting straight into the middle. The Blackfoot is strong on caddis and big bugs, and the Clark Fork is producing on a big stonefly and San Juan Worm dropper.

What is biting on the Flathead River right now?

Trout, and the dry-fly bite has been exceptional. Guide Ryan Stultz of Bent Fly Fishing reports the Flathead is fishing great, especially midday and late afternoons, with lots of active fish willing to eat off the top.

What is the best wade-fishing tip for the Flathead?

Do not walk up and cast into the middle of a pretty hole, since you may cast over or stand on fish. Start at the inside edge closest to the bank, make a few casts, then step out and work each seam into the heart of the hole and the far edge.

How is the Blackfoot River fishing?

Well. The salmonfly hatch has dwindled a bit, but big bugs are still around and fish will eat them, and there are piles of caddis out. That keeps the dry-fly fishing strong. Focus on where bugs are hatching and fish those areas patiently.

How is the Clark Fork River fishing?

Solid, even on a busy day with multiple boats. The water is still high, and a dropper rig with a big stonefly on top and a San Juan Worm below was the ticket. Pheasant tail and tungsten bead jig nymphs and stoneflies were also getting eaten.

What is the outlook for the Montana rivers?

All three rivers are fishing great heading into summer. These are standard fly patterns rather than Catch America products, so we name them without shop links. Specific fish sizes and counts were not specified in this report.
