- Fly only
A southwesterly has held for two days, running warmer than the water (15°C air against 10°C water). Expect fish at the north-eastern end — the bank it is blowing into — where the drift piles food, colour and warmth together. This reads the upper water, though — a bottom bait at range feels it far less than a floater or a fish in the margins. 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.
Watch for Sedge towards evening — this could be the best window of the day.
Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.

A good match for Llyn Tecwyn Uchaf — most conditions are close to what it fishes best in.

- Wind conditions (ripple) closely match what this water fishes best in.
- Buzzer is in its seasonal window, boosting the chance of targeted feeding.
