Find It in the Box

Turn the selected section into a physical fly, rig, and starting presentation.

Orient the box

Start with the section labels, not every fly.

Open the box so the printed headings and decision cards read upright. Use the Surface, Film, or Subsurface section indicated by the river clue. The section label gives you the next decision without requiring a memorized fly address.

Below the surface

Subsurface

Nymph, larva, pupa, wet-fly, soft-hackle, and streamer choices that fish below the surface.

On or near the surface

Surface + Film

Dry flies, emergers, and other choices that fish on top or in and just below the surface.

Follow the card

Move from a broad clue to one labeled box position.

  1. Open Surface, Film, or Subsurface.Use the section chosen from the river clue.
  2. Use the decision card.Compare size, then shape, then color when color is useful.
  3. Follow the box reference.Locate the labeled box position first, then confirm size and pattern.
  4. Use the matching rig.The fly choice points forward to the rig and starting presentation.

Complete example

Repeated rises lead to a Surface fly.

River clue → box action

Repeated rises → Surface → decision card → labeled fly position.

Open the Surface decision card. Compare the visible food by size and shape. Choose the closest fly in the indicated position. Then open the matching dry-fly rig and starting presentation.

This is the same path used throughout the website: observe, choose the section, find the fly, rig it, fish the starting presentation, and make one deliberate adjustment.
