Streamer Fishing for Trout: How to Catch Big Fish

If you want to catch the biggest trout in the river, learn how to fish streamers. Streamers imitate baitfish, sculpins, leeches and crayfish, the big meals that large trout hunt. Instead of waiting for a fish to sip a tiny bug, you’re covering water and triggering an aggressive strike. When it works, it’s the most exciting fishing there is.

This guide covers streamer fishing techniques for trout: the gear you need, the best streamer flies, where to fish them, how to retrieve streamers and how to set the hook.

Why Streamers Catch Big Trout

As trout grow, they need bigger meals. A 20-inch brown trout can’t live on midges alone, so it eats sculpins, small trout, crayfish and minnows. Big fish are also territorial, so a streamer swimming through their spot can trigger a strike from pure aggression. Streamers aren’t always the most productive way to catch numbers of fish, but they often catch the biggest.

Streamer Fishing Gear

Rod: a 9 ft, 6 or 7 wt with a fast action. A 5 wt works for small streamers on small water.
Line: a floating line works for shallow water and small flies. A sink-tip line gets heavy flies down fast in deep runs and from a drift boat.
Leader: short and strong. 4 to 7 feet of 0X to 2X. Trout chasing a streamer aren’t leader shy.
Flies: a handful of proven patterns in olive, black, white and tan.

Best Streamer Flies for Trout

Woolly Bugger: the most versatile streamer ever tied. Fish it in olive, black or brown.
Sculpin patterns: big, flat heads that ride along the bottom. Brown trout love them.
Zonker: a strip of rabbit fur that pulses and breathes in the water.
Clouser Minnow: a weighted baitfish that rides hook-up and jigs on the strip.
Articulated streamers: big, two-hook flies with lots of movement for trophy trout.

Match the color to the light: dark flies on dark days or dirty water, light flies in clear water and bright sun.

Where to Fish Streamers

Big trout hold near cover and close to deep water, where they can ambush food without fighting the current all day.

Undercut banks and shade: cast tight to the bank, within a foot if you can, and strip the fly back out.
Deep runs and buckets: swing the fly through the deepest water, letting it sink first.
Logjams and downed trees: some of the best big-fish cover in any river. Strip the fly right past it.
Tailouts and shallows at low light: at dawn, dusk or on cloudy days, big trout move up to hunt in shallower water.

How to Retrieve Streamers

How you move the fly matters as much as which fly you pick. Start with these four retrieves and change them up until the fish tell you what they want.

Steady strip: even strips of 6 to 12 inches. A great way to search new water.
Strip-strip-pause: two quick strips and a pause. The fly darts and then falls, and many fish eat right on the pause.
The swing: cast across the current, mend, and let the current swing the fly across the run. Strikes are often hard, so hold on.
Dead drift and twitch: let the fly drift like an injured baitfish, with a small twitch every few seconds. Deadly in cold water.

Water temperature matters. In cold water (below about 45°F), fish slow and deep. In warmer water, strip faster. Trout are more willing to chase when they’re active.

Setting the Hook: The Strip Set

The biggest mistake new streamer anglers make is lifting the rod like they would with a dry fly. That pulls the fly away from the fish. Instead, use a strip set: keep the rod tip low and pointed at the fly, and when you feel the fish, give a long, hard strip with your line hand. Once the fish is hooked, then lift the rod.

Best Conditions for Streamer Fishing

Cloudy, dark days when big trout feel safe in the open.
Rising or slightly stained water after a rain, when baitfish get pushed around.
Early morning and evening in summer.
Fall, when brown trout get aggressive before spawning.

Go Hunt Some Big Fish

Streamer fishing is active, exciting and a great way to find the biggest trout in your river. Bang the banks, mix up your retrieve and strip set when they eat. Before you go, check your leader and tippet setup and brush up on your casting; heavier flies need a slightly slower, more open stroke.
