Note: Rules on hooks, barbs, and catch-and-release vary by water, and many trout streams require barbless hooks. Check your state's rules.

When it works best

  • When trout are rising and feeding on insects at the surface.
  • During hatches in the morning and evening.
  • In calm, clear water.

How to fish it

  1. Match the size and shape of the insects you see.
  2. Cast upstream or across the current.
  3. Let the fly drift without drag, which means moving at the same speed as the water.
  4. Mend the line to keep it drifting naturally and set the hook gently when a fish rises.

Tips

  • Use floatant to keep the fly high on the water.
  • Watch what the fish are eating before choosing a fly.
  • Fish the seams and calm pools.

Common mistakes

  • Letting the line drag the fly, which looks unnatural.
  • Using a fly that is too big.
  • Casting too close to the fish.

Gear

A light fly rod, with a floating line and a long, fine leader, is the usual setup.

Often confused with

  • Nymph: sinks beneath the surface.

Field notes

Watching a trout rise to a dry fly is one of the highlights of fly fishing. It starts with watching the water and the insects.
