A southwesterly has held for 11 hours, running colder than the water (2°C air against 7°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 Minkie (6-10) — on the point. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely.
Slow down everything. A booby on a fast-sinking line, left static, can pick up deep fish.
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.

A reasonable day here, though cloud isn't quite in the sweet spot.
Fly and bait both allowed; locally farmed stock with the occasional tagged fish carrying a cash prize.
A medium reservoir in Upper Teesdale, set in the moorland above Barnard Castle with four miles of bank and a series of bays and inlets that give it more edge than a single-basin water of the same size.
