The Williams Fork is fishing well despite low and clear water. Trout are on high alert so you’ll need to make sure you move with caution and stick with short and clean casts. While nymphing has been the most effective way to fish as of late, surface action has been good as well. The BWO hatch has been particularly fun and productive which should be fairly strong this week with extended periods of cloud cover and moisture in the air. Otherwise when nymphing, bigger lead flies like a Pat’s, Egg Sucking Leech, Flashback PT, Hare’s Ear or Copper John followed by one or more smaller imitative midge, baetis or caddis patterns will produce the best results. As far as trailer flies go, keep it simple. Zebra Midges, Black Beauties, Mercury Midges, Tube Midges, RS2s, Darth Baetis and Juju Baetis are a few of our go to patterns right now. Depth will be imperative to success, however. Low air pressure this week will have trout holding in the deeper water columns most of the day so ensure plenty of weight and adjust your indicator accordingly. Yarn indicators will be the most effective as they will create less of a disturbance on the water and lighter tippet will also go a long way. Otherwise, a dry dropper fished along the banks and through the faster seams and riffles will likely produce as well.
