One streamer I am never without is the Alexandra in sizes 8-12 in small rivers/creeks. 2-6 in bigger rivers. It is a bright fly with a lively peacock wing. You tie the wing with long, irridescent swords instead of the herl used for bodies. The red tail and cheeks are killer. Normally it has a silver embossed tinsel body but I have used copper with great results as well.
Fish it slowly in a deep pool or rip it across a moderate riffle.
