I thought I would pass on a terrific fly pattern that I’ve been using with great success on Oregon and Idaho waters. I designed The DD Nymph about 5 years ago, and since then it has out-fished just about every other fly pattern in my fly box. It’s a great little nymph to drift along the stream bottom or as a dropper to a larger dry fly, and has been especially effective when there don’t seem to be many bugs hatching. I suspect that fish take this fly as a small cased caddis, but who knows. Anyway, if you tie your own flies, you should whip out a few of these for your fly box.
The DD Nymph
