How to fish it · for Rainbow
When
Current conditions suit Thornwood Springs Trout Fishery well for summer tactics. The ripple should help fish move and feed more confidently.
Where
Start with Diawl Bach (12-14) — on the bob / top dropper — slow figure-of-eight retrieve. 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 Diawl Bach (12-14) — on the bob / top dropper — slow figure-of-eight retrieve. 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
Fish early and late, try deeper during the heat of the day with a fast-sinking line.
Watch for
Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.
Bank
Bank fishing near inflows, dam walls, and weed beds. Move to find feeding fish.
