Head to
Wind driftSW wind
North-eastern end

A southwesterly has held for 8 hours at much the same temperature as the 16°C water. No thermal steer either way, but the drift still stacks food against the north-eastern end — the bank it is blowing into — so start there. 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 Rainbow
When
Conditions are not ideal but fishable at Sources de l'Éclimont. The ripple should help fish move and feed more confidently. Dawn is the prime window when warm water pushes fish deep during the day. The surface has cooled overnight and trout may be feeding in the upper layers — make the most of this before the sun gets up.
Where
Start with Viva (10-12) on a figure-of-eight with occasional strip. Early in the day, try buzzers on a slow figure-of-eight or a booby on a fast-sink line near the bottom. Rainbows respond to more active retrieves — try short strips between pauses. When no hatch is visible, a buzzer team — black stripped quill on the point, attractor or pearl-rib on the top dropper — is the default starting point on any UK stillwater.
The plan
Plan A

Start with Viva (10-12) on a figure-of-eight with occasional strip. Early in the day, try buzzers on a slow figure-of-eight or a booby on a fast-sink line near the bottom. Rainbows respond to more active retrieves — try short strips between pauses. When no hatch is visible, a buzzer team — black stripped quill on the point, attractor or pearl-rib on the top dropper — is the default starting point on any UK stillwater.

Plan B

A fry-imitating pattern stripped through the margins can save a blank in autumn.

Watch for

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

Bank
