A westerly has held for 9 hours, running colder than the water (10°C air against 13°C water). The end it blows into is taking that chilled surface water, so try the sheltered 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 Balanced Leech (8-12) on a As per local 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.
