The field decision sequence

How the system works.

A clear progression from observing the river to making the next informed adjustment.

Upper Au Sable River
The river provides the first evidence. The system organizes the response.

One connected progression

Observe. Choose. Find. Rig. Fish. Evaluate.

Observe the river

Check conditions and visible activity.

SCOPE organizes these same field decisions from arrival to the first informed presentation.

SCOPE
Choose a start

Let the river choose surface, film, or subsurface.

This is the starting row, not a promise of success.

Starting row
Find the fly

Refine by size, shape, and then color when color matters.

Color appears only when it is a useful secondary cue.

Box logic
Rig and present

Match the rig to the selected presentation and water.

Choose a specific lane and make the first drifts repeatable.

Controlled test
Evaluate

Change one thing at a time so you know what helped.

Repeat the same lane, then change one variable at a time.

Adjust
Record and learn

Connect the result to the conditions.

Field notes and River Intelligence turn individual outings into accumulated river knowledge.

Choose one lane

Narrow the river to one clear test.

Use what the water shows you to choose one repeatable lane instead of trying to fish everything at once.

Fish, then evaluate

Make the presentation repeatable.

Fish the chosen lane consistently, evaluate what happened, then change one useful variable at a time.

What to change next

The adjustment depends on how you are fishing.

The box gives each method its own next-step path. Change one useful variable at a time so the result teaches you something.

Dry fly

Presentation and drag first.

Improve how the fly travels, then reassess size and shape.

Film / soft hackle

Position and presentation first.

Confirm the fly is in or just below the film, then reassess size and shape.

Nymph

Presentation → Depth → Weight → Change Fly.

Repeat the same lane after each change.

Streamer

Angle, retrieve, and depth first.

Change the fly only after testing how it moves through the water.
