- Fly only
A northwesterly has held for 6 hours, running colder than the water (9°C air against 12°C water). The end it blows into is taking that chilled surface water, so try the sheltered north-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. Early in the day, nymphs and buzzers fished slowly tend to outperform attractors.
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.

A reasonable day here, though wind isn't quite in the sweet spot.

- Wind conditions (windy) are not ideal for this water.
- Temperature (cool) is in the sweet spot for autumn fishing.
- Lake Olive is in its seasonal window, boosting the chance of targeted feeding.
- Reservoirs of this kind fish well at this time of year.
