Severe drought restrictions (crise) in force

VigiEau lists this venue's surface-water zone (Plateau calcaire, dépt 39) at crise, under an official préfectoral drought arrêté. Fishing is not itself banned by it, but water levels are low — go gently on stressed fish.

How to fish it · for Trout
When
Conditions are not ideal but fishable at Lac de Vouglans. 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

A fry-imitating pattern stripped through the margins can save a blank in autumn.

Watch for

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

Bank

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