How to fish it · for Trout
When
Conditions are not ideal but fishable at Lac de Serre-Ponçon. Flat calm means fish may be spookier — longer leaders and subtler flies will help.
Where
Start with Perdigón (14-18) — 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 Perdigón (14-18) — 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.
Bank
Flat calm suits bank fishing near features — points, weed beds, and inflows where fish patrol.
