How to fish it · for trout
When
Conditions are not ideal but fishable at Lake Robertville. 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. 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. 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.
