How to fish it · for rainbow
When
Current conditions suit Lake Bütgenbach well for summer tactics. 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 Damsel Nymph (10-12) — on the point — slow figure-of-eight retrieve. 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 Damsel Nymph (10-12) — on the point — slow figure-of-eight retrieve. 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.
Boat — drift
A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.
