How to fish it · for Rainbow
When
Current conditions suit Innis Fly Fishery well for autumn tactics. The ripple should help fish move and feed more confidently.
Where
Start with Floating Fry (8-10) on a Fish as a single fly. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely.
The plan
Plan A

Start with Floating Fry (8-10) on a Fish as a single fly. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely.

Plan B

A fry-imitating pattern stripped through the margins can save a blank in autumn.

Watch for

Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.

Bank

Bank fishing near inflows, dam walls, and weed beds. Move to find feeding fish.
