How to fish it · for Rainbow
When
Current conditions suit Lake Robertville well for autumn 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. Early in the day, try buzzers on a slow figure-of-eight or a booby on a fast-sink line near the bottom. Rainbows respond to more active retrieves — try short strips between pauses.
The plan
Plan A
Start with Diawl Bach (12-14) — on the bob / top dropper — slow figure-of-eight retrieve. Early in the day, try buzzers on a slow figure-of-eight or a booby on a fast-sink line near the bottom. Rainbows respond to more active retrieves — try short strips between pauses.
Plan B
A fry-imitating pattern stripped through the margins can save a blank in autumn.
Watch for
Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.
Bank
Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.

Rainbow fly box
A practical Walloon stillwater pack for Ardennes reservoirs and stocked lakes where stocking history, bank access and wind matter more than classic river drift-fishing. Small lures, buzzers, nymphs and simple streamers belong here.
