Père Igor

Chambon is a lava-dammed lake — the Tartaret volcano erupted some three thousand years ago, sent a lava flow down the valley, and blocked the Couze Chambon river where it runs out of the Monts Dore.

How to fish it · for trout
When
April–June and September
Where
With limited drift, anchor or fish static from sheltered positions. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. In the calm, a single dry fly or a slowly-fished nymph tends to out-fish an active retrieve.
The plan
Plan A

With limited drift, anchor or fish static from sheltered positions. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. In the calm, a single dry fly or a slowly-fished nymph tends to out-fish an active retrieve.

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

Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.

Bank

Flat calm suits bank fishing near features — points, weed beds, and inflows where fish patrol.

About this water

Chambon is a lava-dammed lake — the Tartaret volcano erupted some three thousand years ago, sent a lava flow down the valley, and blocked the Couze Chambon river where it runs out of the Monts Dore. The result is a fifty-hectare lake in a wide, sunny basin with the volcano sitting at one end and the fishing going on at the other. It gets busier than Pavin or Chauvet in summer because it has beaches and pedaloes and all the apparatus of a proper French family holiday, which is fine — you just fish it in the hour before the pedaloes come out. Trout and perch, standard cast. The inflow at the east end and the outflow by the Tartaret are both worth time. Not the most remote water in the Massif Central, but a good lake all the same if you pick your hours.
