How to fish it · for Trout
When
Current conditions suit Lac de Serre-Ponçon well for winter tactics. The ripple should help fish move and feed more confidently. Warmer water may push fish deeper — try sinking lines or deeper nymphing.
Where
Start with Perdigón (16–18) — 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 (16–18) — on the point — slow figure-of-eight retrieve. If that does not produce, switch depth or speed before changing the pattern entirely.

Plan B

Slow down everything. A booby on a fast-sinking line, left static, can pick up deep fish.

Watch for

Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.

Either bank or boat

Good ripple suits both bank and boat. Bank: work inflows, dam walls, and points. Boat: broadside drift covering wind lanes.

About this water

It is a mixed fishery in the fullest sense: wild trout in the feeder streams at the head of the lake, perch and pike along the drowned willow edges, pike-perch out in the deeps, and the occasional large brown that has grown up on a diet of whatever else swims in here. Fly fishers come for the pike — large flies, floating line, patient probing of the drop-offs — and for the first and last light hour when the trout move onto the shallow margins at the Savines end. The water level drops sharply through summer for irrigation release, which exposes and reshapes the banks faster than any fishery has a right to expect, so take local advice on what is currently reachable. Absurdly scenic; genuine quarry.
