- Fly only
A northeasterly has held for 7 hours, running colder than the water (7°C air against 10°C water). The end it blows into is taking that chilled surface water, so try the sheltered north-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.
Set up a broadside drift and cover the water systematically. 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.
A good match for Llyn Bochlwyd — most conditions are close to what it fishes best in.

- Temperature (cool) is in the sweet spot for autumn fishing.
- Lake Olive is in its seasonal window, boosting the chance of targeted feeding.
