How to fish it · for Trout
When
Conditions are not ideal but fishable at Lac de Serre-Ponçon. The ripple should help fish move and feed more confidently. Very warm conditions — trout have a narrower safe zone of cool, oxygen-rich water. Fish only at first light or last light, use barbless hooks, keep fish in the water during release, and stop if fish struggle to recover.
Where
Start with Perdigón (16-18) — on the point — slow figure-of-eight retrieve. Early in the day, nymphs and buzzers fished slowly tend to outperform attractors.
The plan
Plan A
Start with Perdigón (16-18) — on the point — slow figure-of-eight retrieve. Early in the day, nymphs and buzzers fished slowly tend to outperform attractors.
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.
Either bank or boat
Good ripple suits both bank and boat. Bank: work inflows, dam walls, and points. Boat: broadside drift covering wind lanes.
