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 driftS wind
Northern end

A southerly has held for 16 hours, running warmer than the water (17°C air against 15°C water). Expect fish at the northern end — the bank it is blowing into — where the drift piles food, colour and warmth together. This reads the upper water, though — a bottom bait at range feels it far less than a floater or a fish in the margins. 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

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 — at anchor

Windy conditions suit anchoring in productive areas rather than open-water drifting.

About this water

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. 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.

Why this score
  • Wind conditions (windy) are not ideal for this water.
  • Cloud cover (cloud) suits the fishery well.
  • Temperature (cool) is in the sweet spot for autumn fishing.
  • Buzzer is in its seasonal window, boosting the chance of targeted feeding.
