Eastern end
A westerly has held for 6 hours, running warmer than the water (19°C air against 13°C water). Expect fish at the eastern end — the bank it is blowing into — where the drift piles food, colour and warmth together. This reads the upper water, though — a bottom bait at range feels it far less than a floater or a fish in the margins. Treat it as a tiebreaker between good swims rather than an override — features and angling pressure usually count for more.
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 (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
If the main plan stalls, drop to a size 14–16 midge — switch to a washing-line or suspender rig and change drift line before you change food group.
Watch for
Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.
Either bank or boat
Calm evenings can fish well from bank or boat — target rising fish wherever you find them.
