Head to
Wind driftW wind
Eastern end

A westerly has held for 8 hours, running warmer than the water (12°C air against 9°C water). Expect fish at the 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.

How to fish it · for Rainbow
When
No strong hatch signals at the moment — general searching tactics should work best. The ripple is helpful — fish should move onto the feed and a slow-drifted team or single wet will cover water well.
Where
Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
The plan
Plan A

Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.

Plan B

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

Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.

Boat — drift

A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.
