Lac Chauvet

Aerial view of the round volcanic Lac Chauvet surrounded by forest and farmland in the Monts Dore, Puy-de-Dôme, France

Chauvet is smaller and less famous than Pavin, which is the case for most lakes in the Monts Dore and is generally why they reward the visit.

Severe drought restrictions (crise) in force

VigiEau lists this venue's surface-water zone (13 - Dordogne amont, dépt 63) 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.

Arrêté préfectoral n°37758 ↗

Temporary notices from official orders and recent fishery reports — they clear automatically once out of date. Always confirm locally before travelling.

Head to
Wind driftS wind
Southern end

A southerly has held for two days, running colder than the water (16°C air against 17°C water). The end it blows into is taking that chilled surface water, so try the sheltered southern end instead — off the back of the wind, where the undertow returns food along the bottom. That chill sits in the top of the water, though, and the bed is slower to feel it — on a bottom bait it is the undertow, not the temperature, that puts you at this end. Treat it as a tiebreaker between good swims rather than an override — features and angling pressure usually count for more.

Where
Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
The plan
Plan A

Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.

Plan B

If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.

Watch for

Watch for Sedge towards evening — this could be the best window of the day.

Bank

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

About this water

Chauvet is smaller and less famous than Pavin, which is the case for most lakes in the Monts Dore and is generally why they reward the visit. It is another volcanic crater — same genesis, similar geometry, similar clear cold water — and it is one of the quieter fly venues in the Auvergne on any given day. The fish are small and wild and behave like fish that have not been hammered. Shore access is straightforward; boats are not generally needed. This is the sort of water you drive to when you want to spend a long afternoon casting small flies at a beautiful piece of crater without having to think about anything else, which is a kind of fishing that gets undervalued by people who measure success in centimetres.
