A southwesterly has held for 17 hours, running colder than the water (10°C air against 12°C water). The end it blows into is taking that chilled surface water, so try the sheltered south-western 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.
Start with Perch Fry (8–10 long shank) — on the point. If that does not produce, switch depth or speed before changing the pattern entirely.
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.
Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.

Conditions are away from Dungonnell Reservoir's sweet spot — it usually fishes best in ripple wind with cloud skies.
