How to fish it · for Trout
When
Conditions are not ideal but fishable at Lac de Vouglans. The ripple should help fish move and feed more confidently.
Where
Start with Small Perdigón (16-20) — 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 Small Perdigón (16-20) — 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

Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.

About this water

Lac de Vouglans is a great turquoise reservoir held in a gorge of the southern Jura, a deep water of limestone character that takes on the colour of mineral country in still light. Its trout are scattered across a large lake, which means the angler's first task is to find them rather than fool them. Work from a boat, cover ground, and let the wind and the drop-offs narrow the search. The depth keeps the lake cool when summer presses, and the better fish often lie well down. It is patient, exploratory fishing — but a Vouglans trout, found and fairly taken, repays the looking.
