A southeasterly has held for 8 hours, running colder than the water (4°C air against 9°C water). The end it blows into is taking that chilled surface water, so try the sheltered south-eastern 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.
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.
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.
Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.
A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.

Closer to wild-lake trout fishing than to competition réservoirs. More room for naturals, caddis, buzzer, terrestrial and modest lure use.
A reasonable day here, though cloud isn't quite in the sweet spot.
Feral rainbow and wild brown trout. Best spring through early autumn fishing. Fly-fishing opportunity on this substantial lake. Check Finistère regulations for permits and daily catch limits. Car-accessible lake fishing with good potential.
