How to fish it · for Rainbow
When
Current conditions suit Thornwood Springs Trout Fishery well for autumn tactics. The ripple should help fish move and feed more confidently.
Where
Start with Viva (10-12) on a figure-of-eight with occasional strip. 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. When no hatch is visible, a buzzer team — black stripped quill on the point, attractor or pearl-rib on the top dropper — is the default starting point on any UK stillwater.
The plan
Plan A
Start with Viva (10-12) on a figure-of-eight with occasional strip. 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. When no hatch is visible, a buzzer team — black stripped quill on the point, attractor or pearl-rib on the top dropper — is the default starting point on any UK stillwater.
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-only venue. Fish from accessible margins, points, weed edges, and inflows.
