A southeasterly has held for most of a day, running colder than the water (12°C air against 17°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.
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.
Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.

Numbers are intensity 0 (none) to 3 (peak) — a guide, not a guarantee.
More straightforward stocked-water behaviour than the upland competition reservoirs, with stronger early-season lure and booby bias but still good natural-fly periods.
A reasonable day here, though wind isn't quite in the sweet spot.
Remote upland llyn at 1,400ft on Plynlimon. Wild brown trout in an exposed, windswept setting. Access by 2-mile walk from the road. Classic Welsh hill llyn — traditional wet flies and dabblers on a breezy day. Fish average 6–10oz but beautifully marked. The Shepherd's Lake.
