Lac Pavin

Lac Pavin — Besse Lac Pavin1

Pavin is the youngest volcano in mainland France and it is perfectly, almost unnervingly round — as if someone had placed a compass at the centre and drawn the shoreline in a single gesture.

Head to
Wind driftN wind
Northern end

A northerly has held for 9 hours, running colder than the water (0°C air against 6°C water). The end it blows into is taking that chilled surface water, so try the sheltered northern 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.

How to fish it · for Trout
When
Through the open lake season. Spring buzzers and damsels April through June; daphnia mid-summer; sedges into September.
Where
Drift lines along the volcanic-crater margins. Pavin is a small deep maar lake — fish hold on structural edges of the steep-sided basin.
Method
Drift on a floater with team-of-three traditional wets in spring; midge-tip in summer. The small lake size doesn't need a drogue.
Kit
10 ft #6 boat rod; floating, slow-intermediate, and sink-tip lines; 5 to 6 lb fluoro tippet. Drogue and a long-handled net.
The plan
Plan A

Set up a broadside drift and cover the water systematically. 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

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

Boat — drift

A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.

About this water

Seven thousand years ago there was a phreatomagmatic eruption here; now there is a crater lake ninety-two metres deep with water so cold and so still at the bottom that it has not mixed properly in anyone's memory (the word is 'meromictic', which is the sort of word that usually wins people drinks in bars). The ecology is exactly what you would expect: cold, oligotrophic, and perfect for salmonids. Arctic char live in the deeps, brown trout work the shoreline in the shoulders of the season, and perch do whatever perch do in a place like this. Boat fishing is permitted and is genuinely the best way to fish Pavin, because the crater is round and the wind is usually from somewhere you will want to row away from. Beautiful water; serious fishery.
