Imitates a salmonfly nymph. This fly must be fished on the bottom. Period. So weight it heavily under the body, then flatten the weight with pliers. For extra weight, put on a beadhead. Or two. Yes, you're going to lose a lot of flies, but you're also going to catch a lot of trout.

Some anglers who tie their own flies will carry two salmonfly nymph imitations: this one and a Rubber Legs. The latter is not as accurate an imitation, but it is a lot faster to tie. These anglers use the Rubber Legs in fast water where the trout don't have time to take a close look; that way they don't feel so bad if they lose the fly in the rocks.

The Kaufmanns Stonefly is one of the great western trout flies. Over the decades, the rubber legs and sometimes a bead head (or two) have been added. It has been often imitated, but this is the salmonfly nymph that anglers keep coming back to.



Golden stonefly nymphs are a mottled tan color, not golden. However, some nymphs are golden color--apparently just after molting. The bright color stands out like neon to a trout, so sometimes a golden colored fly can be effective.


How to Fish

Dead drift on the bottom with an trout indicatoror tight line presentation. The best areas are bouldery sections, riffles, and just below riffles. If you find a moderatre drop-off just below a riffle, consider yourself blessed.
