How to fish it · for Rainbow
When
Year-round. Winter (Nov–Feb) excellent on sinking line and lure. Spring (Mar–May) and autumn (Sep–Oct) best for buzzer and nymph.
Where
Start with Cormorant (10-12) — on the bob / top dropper. 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 Cormorant (10-12) — on the bob / top dropper. 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-only venue. Fish from accessible margins, points, weed edges, and inflows.
