Trout Fishing: Gear and Setups

Cold-water fish with soft mouths and sharp eyesight, which makes line size and hook size matter more than for almost anything else in freshwater.

Also known as Rainbow trout, brown trout, brook trout, cutthroat.

Trout rigs: spinners, bait under a bobber, bait off the bottom and drifting

Four simple rigs that state agencies teach for trout in lakes, ponds and streams. Check the water's rules before you tie one on: some trout waters allow artificial lures only, or single barbless hooks.

Inline spinner

Cast and reeled back to cover water. In a stream, cast slightly upstream and take up the slack as it comes down; in a lake, let it sink a little before you start reeling.

Lure
1/16 oz spinner
Line
4–6 lb monofilament on a light spinning outfit

Bait under a bobber

A piece of worm or a scented dough bait hung under a float in a lake or pond, with a small split shot just above the hook to sink it.

Hook
#8 bait hook for a piece of worm; for dough bait, a #16–#18 treble, as in the next rig
Float
1½ to 3 feet above the hook to start, then adjust to where fish are

Floating bait off the bottom

A buoyant dough bait such as PowerBait on a short leader behind a sinker. The sinker rests on the bottom and the bait floats up above it.

Weight
About 1½ feet above the hook, which sets how high the bait floats
Hook
Small treble, about #16–#18, molded inside the bait

Drifting bait in a stream

Cast upstream of where trout hold and let the current carry the bait along the bottom, reeling in only the slack so you keep pace with it.

Weight
Split shot 12 to 24 inches above the hook, enough to get within a few inches of the bottom
Hook
#14–#10 single hook for salmon eggs; a #8 bait hook for worms
Leader
In clear water, about 2 feet of 2 lb test or lighter, because trout often see heavier line and shy away

Where to find trout

Cold streams, tailwaters below dams, mountain lakes and stocked ponds. Stream trout hold in seams, behind boulders and at the head of pools where current delivers food.

How they feed

Sight feeders that inspect a bait before taking it. In clear water they refuse heavy line and oversized hooks that a bass would ignore completely.

Typical size

Stocked stream trout usually run 9 to 14 inches. Wild fish in small water are often smaller; tailwater and lake fish can be several pounds.

Through the year

Most active in water between about 50 and 65 degrees. In summer they move to springs, riffles and deeper cold water; in winter they hold in slow, deep pools and eat small.

Rainbow trout underwater, with dark spots across its body and tail and a pink band along its side.

Common trout mistakes

Too much hook for the bait

A single salmon egg or a small piece of worm on a #4 hook looks wrong to a trout. Size the hook to the bait: about #14 to #10 for a single egg, #12 to #8 for a piece of worm, and #10 to #6 for a whole nightcrawler or a minnow.

Heavy line in clear water

Ten pound mono on a stocked stream cuts your bites sharply. Four to six pound test is enough for the great majority of trout.

Setting the hook too hard

Trout have soft mouths and treble-hook spinners pull free easily. Lift into the fish rather than swinging.

Sources for the rigs and bait notes

  • Oregon Department of Fish and Wildlife — How to fish for trout Beginner trout rigs: 1/16 oz spinners, #8 bait hooks, 4 to 6 lb monofilament, a piece of worm or a little PowerBait under a bobber 1½ to 3 feet above the hook, floating bait about 1½ feet above a weight, and drifting bait near the bottom with split shot. Checked October 6, 2026.
  • Missouri Department of Conservation — Trout fishing tips Split shot 12 to 24 inches above the hook for drifting, single #10 to #16 hooks for salmon eggs, #16 to #18 trebles for dough and cheese baits, and a 2-foot leader of 2 lb test or lighter, because trout often see heavier line in clear water and shy away. Checked October 6, 2026.
  • Pennsylvania Fish and Boat Commission — Trout Minnows, worms, salmon eggs, corn, cheese and prepared baits drifted on the bottom on a light-wire hook, sizes 6 to 14. Checked October 6, 2026.

Regulations

Many trout waters have specific seasons, tackle restrictions such as artificial-only or single barbless hooks, and separate stamps or endorsements. State agencies publish these per water body, and they change. Confirm before you go.
