FlyCast River Forecast
Difficulty: Intermediate/Advanced
The Williams Fork is fishing great! Flows continue to inch their way higher and are now at a productive level for this time of year. As a result, trout are able to spread out across the water and are feeding more opportunistically. Now is a great time to try your luck at some streamers, particularly if you are fishing closer to the confluence. Go with small to average sized streamers and hit the banks hard as trout are actively waiting in the more shallow water for an easy meal. Short erratic strips that imitate a stunned or struggling baitfish will garner the best results. Otherwise, you cant go wrong rigging up a leech followed by a smaller midge or baetis pattern. In this case, youll dead drift downstream, like you would a nymph rig, and strip your flies back to you like you would a streamer. That said, you cant go wrong with the traditional nymph rig. While caddis larva and stonefly patterns have made for productive lead flies, youll want to focus most of your attention to the smaller imitative patterns. If you find yourself in a slump, dont neglect the eggs and worms.
Ideal Days to Fish: Friday through Sunday

FlyCast River Forecast
Difficulty: Intermediate/Advanced
Flows on the Williams Fork jumped slightly over the last several days, but it didnt have a meaningful impact on fishing. Fishing here can be tricky and is often hit or miss. Weve found that trout here are particularly sensitive to changes in air pressure. However, a strong hatch will easily swing the odds in your favor. This weekend, air pressure is set to be low, but hold steady. While trout will be fairly selective during this time, you will have success nymphing with bigger lead flies like a Pats, leech or worm pattern. Trail any of the aforementioned lead flies with one or more smaller midge or baetis patterns in the imitative and neutral color variety. Mercury Midges, Black Beauties, RS2s, Darth Baetis and Foam Back Emergers have produced consistent results. Otherwise, don't hesitate to throw a caddis larva or egg into the mix. Hatch activity has been consistent with previous weeks, but lower in variety. While you can still get away with a hopper, terrestrial activity has largely subsided with several days of freezing overnight temps. Midges, by a long shot, have been the most prolific hatch. Parachute Adams and Griffiths Gnats are always great options, but dont hesitate to mix it up with a CDC Transitional/Emerger Midge. Otherwise, BWOs have been hatching in the early morning so come prepared with some Parachute BWOs and CDC Biot Comparaduns.

The Blue Quill Angler
Clarity: Excellent
14 Day Forecast: Look for hatches of midges, BWOs, and Tricos
Tips and Other Information: Flows are perfect on the Willies Fork. Anglers are catching mostly browns, with the occasionally rainbow. Its hard to go wrong with a San Juan Worm, trailed by a Buckskin or Mercury Flashback Pheasant Tail right now. A Sparkle Wing RS 2 is another great fly. For dry flies, a Mathews Sparkle Dun (BWO) or AKs Red Quill is an excellent choice. Dry and droppers are never a bad idea in the skinny riffles where trout are feeding on Baetis nymphs and midge pupae.
Effective Patterns: #20-22 Sparkle Wing RS 2, #18-20 Mercury Flashback Pheasant Tail, #14 earthworm brown San Juan Worm, #18 Buckskin, #20-22 Chocolate Foam Wing Emerger, #18-20 Jujubaetis, #20 Sparkle Dun, #22-24 Stalcups CDC Biot Trico Comparadun, #16 AKs Red Quill, and #22 Matts Midge
