Pteronarcys californica

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

This Skwala nymph still has a couple months left to go before hatching, but it's still a good representative of its species, which was extremely abundant in my sample for a stonefly of this size. It's obvious why the Yakima is known for its Skwala hatch.
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.

This is a young of the year brook trout that I caught and released after a quick picture. I included it here since it's about of the size one might imitate with a streamer.

I apologize for the horrible quality of the picture; this was taken a year or two (and a camera or two) before I started Troutnut.com and learned how to do photography.
