How to fish it · for Rainbow
When
The murrough is on at Pollaphuca / Blessington Lakes. The ripple should help fish move and feed more confidently. Evening can bring a surface rise — have a dry fly or emerger ready.
Where
Start with Bibio (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 Bibio (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
If surface work dries up, try a diawl bach or hare's ear on the point and skate a sedge pattern on the bob at last light.
Watch for
Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.
Either bank or boat
Good ripple suits both bank and boat. Bank: work inflows, dam walls, and points. Boat: broadside drift covering wind lanes.
