How to fish it · for rainbow
When
The buzzer is on at Fernworthy Reservoir. The ripple should help fish move and feed more confidently.
Where
Start with Marabou Damsel (8-12) — on the point. 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 Marabou Damsel (8-12) — on the point. 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
If the main plan stalls, drop to a size 14–16 midge — switch to a washing-line or suspender rig and try different depths before you change food group.
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.
