Wet Flies and Soft Hackles: The Oldest Technique in Fly Fishing Still Catches Trout Every Day
Before indicator nymphing, before euro nymphing, before any of the modern subsurface techniques that fill current fly fishing content, there were wet flies. Soft hackles tied on light wire hooks, fished across and downstream on a swinging line, have been catching trout for more than two centuries. They still work. In many situations they work better than anything else. If you have never spent an evening swinging soft hackles through a riffle during a caddis hatch, you are missing something genuinely special about this sport.
Q&A: Wet Fly and Soft Hackle Fishing
What is a wet fly and how is it different from a nymph?
A wet fly is a subsurface pattern designed to be fished with movement, typically swung across and downstream on a tight line, rather than drifted naturally like a nymph under an indicator. Traditional wet flies have soft, swept-back hackle fibers that pulse and breathe in the current, suggesting an emerging insect or a struggling aquatic creature trying to swim. Nymphs imitate specific life stages with precise detail and are fished to drift naturally. Wet flies are impressionistic and rely on movement and current tension to animate the fly and trigger a take.
What do soft hackle wet flies imitate?
Soft hackles occupy an impressionistic middle ground that suggests several things at once. The swinging motion and rising arc of the fly through the current closely resembles an emerging caddis pupa or mayfly nymph swimming toward the surface. The soft, moving hackle fibers suggest legs or gills in motion. Trout that are actively feeding during a hatch eat soft hackles confidently because they look enough like the real thing to trigger the feeding response without being a precise imitation. Some soft hackles also suggest small baitfish or general aquatic food in rivers where fish are opportunistic feeders.
How do I fish a soft hackle wet fly?
The basic technique is the wet fly swing. Cast across the current at roughly a 45-degree downstream angle, mend upstream once to slow the initial drift, then hold the rod steady and let the current swing the fly across and downstream in an arc. The fly begins deep and rises toward the surface as it swings, imitating the movement of an emerging insect. Takes can happen anywhere in the swing but most often occur as the fly rises and completes the arc directly downstream. After the swing, let the fly hang in the current for several seconds before stripping in for the next cast.
When is the best time to fish wet flies and soft hackles?
Soft hackles are most effective during hatches when trout are feeding on emerging insects. Evening caddis hatches and spring BWO emergences are the classic situations. The swinging wet fly imitates the pupal stage rising through the water column, which is exactly what trout are keying on during those hatches. Outside of hatch periods, soft hackles fished on the swing through productive runs and riffles still pick up fish that are feeding opportunistically. In lower light conditions, in broken water, and during any emergence activity, the wet fly swing is worth trying before reaching for a nymph rig.
Do I need special gear to fish wet flies?
No. A standard trout rod and floating line handle soft hackle fishing without any modifications. Use a slightly longer leader than you would for nymphing, typically 10 to 12 feet, to keep the fly line well back from the fly during the swing. A shorter section of tippet in the 4X to 5X range connects to the fly. Some anglers fish two wet flies in tandem, with the point fly on a short dropper a foot or so above the lead fly, which covers two depths in the swing simultaneously. No indicator, no split shot, no complexity required.
Wet Flies and Soft Hackles From Redd's
A partridge soft hackle that has been catching trout for over 200 years of fly fishing history. Redd's carries it because the trout are still eating it. Simple, effective, and correct during any emerging insect activity.
Imitates emerging mayfly and caddis simultaneously, and in some rivers reads as a small baitfish. A versatile starting point for any angler getting into wet fly fishing for the first time.
Built specifically for caddis hatch situations and the swinging retrieve. Works as the top fly in a tandem wet fly rig or swung solo through an evening rise. Triggers fish even when they are not actively feeding on caddis.
How to Fish Wet Flies More Effectively
Reading the Swing
Learning to read the swing is what separates competent wet fly fishing from exceptional wet fly fishing. Watch the line where it enters the water during the swing. Takes on the swing often feel like a sudden stop, a sideways pull, or a sharp jolt that travels up the line before you feel it in the rod hand. Keep a light grip and stay connected to the fly throughout the swing. Set the hook across and downstream with a firm strip of the line rather than a hard upward rod strike, which can pull the fly away from the fish before it closes its mouth.
Fishing the Tandem Rig
Two wet flies on a single leader cover the water column more effectively than a single fly. Tie the point fly to the end of the tippet and attach the second fly on a short dropper section six to twelve inches up from the point fly. The lower fly swings deeper, the upper fly rises higher in the arc. Trout often take the upper fly during the rising portion of the swing, which is the stage that most closely imitates an emerging insect. Experiment with different combinations: a heavier caddis wet on the point and a soft hackle above it, or a wingless wet fly on the point and a soft hackle emerger up top.
Adjusting the Angle
The angle of your cast relative to the current controls the speed and arc of the swing. A cast straight across the current swings quickly and stays in the productive zone briefly. A cast more downstream slows the swing and keeps the fly in the arc longer, which can be more effective in slower water or when fish are being deliberate. Start with a 45-degree downstream angle and adjust based on current speed and where takes are occurring. In faster water, a more downstream angle slows the swing enough to give fish time to commit.
During an Evening Hatch
The evening caddis hatch is the classic wet fly moment. As caddis begin emerging and adults flutter across the surface, trout shift into an aggressive feeding mode that the swinging wet fly is perfectly suited to exploit. Work through the most active rise zones with a soft hackle or caddis wet fly, covering each productive seam with multiple swings before moving downstream. Takes during an active evening hatch can be hard and immediate. Stay focused, keep your grip firm, and enjoy what is one of the most satisfying forms of fly fishing this sport offers.
Wet fly fishing is fly fishing stripped back to its original simplicity. No electronics, no complex rigs, no constant mending and adjustment. A fly, a current, and a swing. The takes are direct and often aggressive, the technique is meditative, and the history behind it connects every cast to centuries of anglers who stood in the same rivers doing the same thing. That is worth something.
