Streamer fishing for big trout

How to rig, cast and strip streamers, when they work best, and how color and retrieve change with water clarity and light.

Streamers imitate baitfish, sculpins, leeches and crayfish: big meals. They don't catch as many fish as nymphs on most days, but they catch more big fish, and the strikes are hard and exciting. Large brown trout in particular become predators that hunt other fish.

Color: a simple rule

Dark day, dark fly; bright day, bright fly is an old rule that's a good start, with one addition for clarity:

How to fish them

The bank shot

From a drifting boat or while wading downstream, cast tight to undercut banks, logs and boulders, then strip the fly back with short, erratic pulls. Strikes often come in the first few strips.

The swing

Cast across and slightly downstream, let the fly sink, then let the current swing it across the run. Add occasional twitches. Hold on at the end of the swing, when the fly turns upstream.

Jig and pause

In cold water, strip slowly and let the fly pause and drop. Weighted streamers like Clousers dive on the pause, which triggers strikes from fish that won't chase.

Tip: Set the hook with a strip set: pull the line sharply with your line hand instead of lifting the rod. If you miss, the fly stays in the water for a second chance.

Reading the strike

Streamer strikes range from a jolting grab to a soft tap or a fish that simply follows the fly. If a trout follows without eating, change the retrieve before you change the fly: speed up, add a longer pause, or make the fly dart sideways. A fish that flashes at the fly and turns away will often eat on the next cast if you slow down. Keep the rod tip low and pointed at the fly so you feel every touch, and keep stripping until the fly is almost at your feet, because big trout often hit right at the end of the retrieve.

Where to find the big ones

Deep outside bends, logjams, undercut banks, and the slow water next to fast currents. Big trout claim the best cover, so fish each spot carefully. A depth map helps on lakes and reservoirs, where trout often cruise drop-offs.

Many streamer waters allow only artificial flies and have special size rules for big trout. Check regulations, and handle large fish carefully. For the other two main approaches, read nymphing and dry flies.
