A northerly has held for 8 hours at much the same temperature as the 8°C water. No thermal steer either way, but the drift still stacks food against the southern 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.
Set up a broadside drift and cover the water systematically. Work Black Pennell on the bob, Olive on the middle dropper, and Marabou Damsel 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.
A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.

Numbers are intensity 0 (none) to 3 (peak) — a guide, not a guarantee.
A good match for Castle Semple Loch — most conditions are close to what it fishes best in.
Terrain map
- Cloud cover (cloud) suits the fishery well.
- Buzzer is in its seasonal window, boosting the chance of targeted feeding.
- Trout 15 March → 6 October
