CDC Soft Hackle · Wet fly

A brown wisp drifting just under the film

A sparse brown CDC soft hackle on a size 14 wet-fly hook, tied to swing or drift as a mayfly emerger for trout and grayling.

A mayfly soft hackle with a slim, ribbed body, a wispy tail and a loose collar of brown CDC. Brown thread, fine copper wire and dun-brown CDC fibres make up the whole fly.

On the water

A soft-hackle wet fly swinging through mid-water

A thin brown body, banded with copper wire, runs back to a few long CDC tail fibres. Up front, a collar of brown CDC flares out like smoke, soft enough to stir in still air. A neat thread head finishes it off.

Fish it in riffles and runs when mayflies start coming off. Let it dead-drift a foot under, then let the line tighten and swing it up through the seam. The CDC breathes on every pause.

CDC hackle is the part to get right. Use only a few turns and keep the fibres long and sparse, so the collar moves in the current rather than clumping into a ball.

Rigging

Tippet

Leader
Nine feet, with fluorocarbon tippet to get it down
  • Fish on 5X or 6X tippet; a long leader helps it sink naturally.
  • Dead-drift it upstream, then let it swing across the current at the end.
  • Skip the floatant. Wet CDC sinks slowly and stays in the film zone.

Where and when

Hatch
Mayfly emergence, typically spring and autumn afternoons
Target
Brown trout, Rainbow trout, Grayling
Water type
Riffles, runs and the soft seams below them
Also fishes
Slow pool tails and stillwater margins, fished slowly on a long leader during midge and mayfly activity.

How to tie it

The steps, from first wrap to whip finish (10)
  1. Mount the size 14 wet-fly hook in the vise and start the brown thread just behind the eye.
  2. Lay a thin thread base back to the bend.
  3. Tie in a small bunch of brown CDC fibres as a tail, about a hook shank long.
  4. Tie in the fine copper wire at the bend.
  5. Wrap the thread forward in smooth, even turns to build a slim, slightly tapered body, stopping two eye-lengths behind the eye.
  6. Counter-wrap the copper wire forward in five or six open turns and tie it off.
  7. Prepare a brown CDC feather and tie it in by the tip just behind the eye.
  8. Wrap two or three turns of CDC, stroking the fibres back with each turn.
  9. Tie off the feather and trim the waste.
  10. Build a small, neat thread head and whip finish.
Proportions (4)
  • Tail: roughly one hook shank in length, sparse.
  • Body: slim, covering the rear three-quarters of the shank.
  • Hackle: CDC fibres reaching to the hook point or just past the bend.
  • Head: small, about one eye-length.
Tips (4)
  • Keep the thread flat while wrapping the body for a smooth, segmented look under the wire.
  • Wrap the copper rib opposite to the body thread so it locks down cleanly.
  • Stroke CDC fibres rearward between turns so they sweep back over the body.
  • Leave plenty of room behind the eye for the hackle and head.
Common mistakes (4)
  • Too much CDC: it clumps and stops moving. Use a single feather and only two or three turns.
  • A fat body: it kills the slim mayfly shape. Build it with thin, even thread layers.
  • Crowding the eye: leave two eye-lengths free before tying in the hackle.
  • Trapping CDC fibres in the head: pull them back before each thread wrap.
