Nearly all of our small streams draining high country are flowing with run-off. This means all Teton River, Fall River, and South Fork tribs. Warm River, running a bit high and clear above the Robinson Creek confluence, is an exception, so is Buffalo River. Try caddis life cycle patterns and your favorite small bead head nymph patterns. On Buffalo and lower Warm River, look for PMDs to become active. Fishing on Birch Creek above Lone Pine is excellent, especially when approached with ultra-light tackle. The aggressive rainbows and brookies here will take just about any pattern, dry or wet, in small and medium sizes.
