Where
Start with Bloodworm (10-14) — 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 Bloodworm (10-14) — 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 fish refuse on top, drop to a buzzer under an indicator at different depths.
Watch for
Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.
Bank
Bank fishing near inflows, dam walls, and weed beds. Move to find feeding fish.
