How to fish it · for Rainbow
When
April–June
Where
Start with Marabou Damsel (8-12) — on the point. Midday in warm weather — switch to a fast-sink or Di-7 and fish boobies or blobs along the bottom. Rainbows respond to more active retrieves — try short strips between pauses.
The plan
Plan A
Start with Marabou Damsel (8-12) — on the point. Midday in warm weather — switch to a fast-sink or Di-7 and fish boobies or blobs along the bottom. Rainbows respond to more active retrieves — try short strips between pauses.
Plan B
Fish early and late, try deeper during the heat of the day with a fast-sinking line.
Watch for
Welshman's Button should come on through the afternoon as the water warms.
Bank
Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.
