It will be wicked cold through the holiday weekend. Some light snow accumulations in the canyon. Flows have dropped, & fishing is tough here with limited open water. Micro mayflies (tricos), & midges are the hatches currently. Light olive to gray for the Mays. Keep them well dressed to ride high in the foam. Pheasant tails, & bird’s nest patterns are best for nymphs. Small parachute midge; or mayfly patterns used with a 10 foot leader are best for surface presentations when the fish are on the midges/or clusters. There are a few sections that can be fished with a dry dropper nymph rig.
