The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

As far as I can tell, this species has only previously been reported from one site in Oregon along the Columbia gorge. However, the key characteristics are fairly unmistakable in all except for one minor detail:
— 4 small yellow spots on frons visible in photos
— Narrow occipital spinule row curves forward (but doesn’t quite meet on stem of ecdysial suture, as it's supposed to in this species)
— Short spinules on anterior margin of front legs
— Short rposterior row of blunt spinules on abdominal tergae, rather than elongated spinules dorsally
I caught several of these mature nymphs in the fishless, tiny headwaters of a creek high in the Wenatchee Mountains.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

I don't have any specific patterns that are better than others but in more general terms I would say I have very good success with thorax dun and comparadun style dry flies. I believe sparseness is better than heavily hackled. Presentation and size is much more important than the fly.

There are dozens of Hendicksons, BWO's, Sulfurs, Cahills, etc but all of the really good flies are going to incorporate certain features that make them good fish catchers.

Put the fly within a few inches of the rise form, not too far above the fish, get a perfect drag free drift and the fish will most likely eat your fly.

Regarding subsurface flies it is hard to go wrong with Hare's Ear, Pheasant Tails, Prince, Some Baetis and Sulfur imitations and round it out with some caddis larvae and pupa and a few generic stonefly patterns.

For streamers a white marabou, a couple of Wooly Buggers in black and brown, a Black Nose Dace, and a couple of Clouser minnows.

I have many, and hyperbolic descriptions for each. They are -most of them- un-tested beyond my own traipsing around.

A thorough search of this forum's past threads will yield some interesting samples.

Here's one: http://www.troutnut.com/topic/8016/KBF-photos-for-Kyle-and-others#37132

What does it catch? http://www.troutnut.com/topic/9234/What-is-it-with-my-biggest-trout-coming-in-NOVEMBER#47053

There's a few for you, Will.

No matter how big the one you just caught is, there's always a bigger one out there somewhere...
