Start with Wet-fly teams (12-14) on a slow, natural presentation — check locally for the preferred method. 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.
A fry-imitating pattern stripped through the margins can save a blank in autumn.
Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.
Good ripple suits both bank and boat. Bank: work inflows, dam walls, and points. Boat: broadside drift covering wind lanes.

Numbers are intensity 0 (none) to 3 (peak) — a guide, not a guarantee.
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 temperature isn't quite in the sweet spot.
At 450 hectares in the heart of the Monts d'Arrée, Saint-Michel is a Grand Lac Intérieur — a big, open reservoir of stocked rainbow trout fished alongside resident pike and perch. This is loch-style water: you fish the wind, the contours and the inflows rather than a pocket of stream. It carries its own lake regulations, separate from the spate rivers all around it, so read the Finistère rules before you launch.
