Memorial Day Weekend kicked off camping season in the canyon, so be prepared for heavy crowds. This will include more anglers, tubers and people looking to enjoy the scenery. Flows are low (51 cfs) and the water clarity is high. Trout are on high alert and tend to favor protective water. Deep pools, runs and large pockets are a safe bet throughout the day. During a hatch, riffles, transitions and pocket water are highly productive. Targeting trout in faster moving water will also give you an advantage as trout have less time to inspect your flies before deciding to eat, so don’t ignore these sections of the river. From a bug perspective, we’ve seen sporadic midge hatches and consistent BWO hatches during the afternoon. Due to cool weather and precipitation caddis activity has been spotty. With more rain in the forecast, this trend will likely continue. If you see rising trout, take full advantage! Parachute BWOs, Hi-Vis BWOs and Parachute Adams are deadly during the early afternoon BWO hatch. Evening midge hatches usually produce solid dry fly opportunities as well. When nymphing, lead with a JuJu Baetis, Flashback Pheasant Tail, Guide’s Choice Hare’s Ear, Electric Caddis or scud. Mercury Black Beauties, Zebra Midges, Chocolate Foam Back Emerges, Sparkle Wing RS2s, Barr’s Emergers and Sparkle Pupas are hot trailer patterns.
