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.

How to fish it · for trout
When
April–September
Where
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.
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

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

Boat — drift

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

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.

Why this score
  • Wind conditions (ripple) closely match what this water fishes best in.
  • Cloud cover (cloud) suits the fishery well.
  • Sedge is in its seasonal window, boosting the chance of targeted feeding.
