A southeasterly has held for most of a day at much the same temperature as the 11°C water. No thermal steer either way, but the drift still stacks food against the north-western end — the bank it is blowing into — so start there. 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.
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.
Sedge should come on through the afternoon as the water warms.
Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.
