Yakima Stoneflies

Going to the Yakima this weekend and looking to tie up some skwalla stones. Anyone have a favorite pattern? I did read that during this time of year it's better to use an adult pattern that's not "big and bushy", like a stimulator, because of the low water. This'll also be the first big test of my fly tying skills, so bring it on! I'll post pictures for the entertainment value:thumb:

I can't get the search function to work for me right now, but look up Pat's stone and Al's skwala on this site.

Here's a nymph pattern from the FFF page I've had bookmarked for awhile but never personally tied. If the link doesn't show the "Yak Skwala", search down the page for the same name from 2004.

Here's the real one from almost exactly one year ago. Notice how silly legs would imitate the tail and antenna nicely on a dry.

Does anyone know the exact material used for the legs on a Pats stone? I am using this rubber floss but it's way too flexible.

My experience is that a dark profile works better for Skwala dry fly patterns on the Yak. One pattern I use is basically a black stimulator (black palmer-hackle over an olive or lighter body and black dyed deer/elk hair wing) with a bright thorax and grizzly hackle. I put a bit of white yarn or z-lon over the hairwing to help my old eyes. I also tie a simpler and lower-floating fly with an olive body (without palmered hackle) and natural brown elk hair wing and grizzly hackle on the thorax. The latter works better in low water or quiet water.

I was told it was superfloss also, but it did not seem to match the color on one of the flies I brought back from Montana last year. I went on a hunt to find exactally what it is on the fly I had. I found a great material developed by Brian Chan and Phil Rowley called Midge Stretch Floss sold through Stillwater Soulutions. They carry it at Puget Sound Fly Company. The color I use on the Brown Pats is called Dark Summer Duck.

Here is a picture of a Stone Fly I use when I fish the Yakima, I call it my Yak Stone. It has worked well on the Yakima, Rock Creek, Naches, and other places too.

Thanks for all the pattern ideas. I tied a few for this past weekend and am happy to report that they caught nothing :( Not much happening with rising fish in general, although there were some adult skwalas in the bushes and a couple seen floating down the river. I totally used the wrong color for the body. Otherwise, I think my pattern's okay.

Thanks,
Chad
