The most effective flies and presentations for sight-fishing rainbow trout in clear water are typically those that imitate local insects, small baitfish, or eggs, and that can be presented delicately to avoid spooking fish. Presentation often matters as much as fly selection—accuracy, minimal drag, stealth, and careful observation are key.
Top Fly Patterns for Sight-Fishing Rainbows
Dry Flies
Parachute Adams (#12–20): Excellent general mayfly imitation and visible on the water.
Elk Hair Caddis (#12–18): Reliable, buoyant dry for caddis and terrestrial imitations, very effective in summer and fall.
Chubby Chernobyl/Chernobyl Ant: High-floating terrestrial for hopper and stonefly seasons—can also hold a dropper nymph.
Foam Beetle: Unsinkable and works both as an attractor and for holding a dropper.
Nymphs
Pheasant Tail Nymph (#16–22): A classic, all-time producer for rainbows in all water types.
Hare’s Ear Nymph: Another staple that works everywhere, especially as part of a tandem nymph rig.
Rainbow Warrior: Flashy attractor nymph, good for pressured or clear water, fishes well as a dropper or in pocket water.
Zebra Midge: Tiny, effective for spooky fish in clear, slow water.
Egg and Attractor Patterns
Egg Flies (Glo Bug, Sucker Spawn): Extremely effective during spawning or when eggs are present in the river.
Lightning Bug: Flashy nymph that works in clear water and as a prospecting fly.
Streamers
Woolly Bugger: Cohesive baitfish and leech imitation, can tempt larger trout or fish that aren’t feeding on top.
Presentation Strategies
Approach slowly, keep a low profile, and use long leaders with fine tippet (5x–6x) for clear water.
Make upstream or quartering casts, presenting well ahead of the fish to minimize spooking and achieve a natural drift.
Utilize high-sticking and tight-line nymphing techniques to minimize drag and maintain flies in the strike zone, particularly around seams, eddies, and behind rocks.
For dries, match the hatch and focus on foam lines, feeding lanes, and where rising fish are spotted.
For nymphs, use indicator or dry-dropper setups, targeting shallow riffles, seams, and slow pocket water where fish are visible.
