Wind driftS wind
Northern end
A southerly has held for 6 hours, running warmer than the water (22°C air against 17°C water). Expect fish at the northern 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 Trout
When
Current conditions suit Gileppe Reservoir well for autumn tactics. The ripple should help fish move and feed more confidently.
Where
Start with Diawl Bach (12-14) — on the bob / top dropper — slow figure-of-eight retrieve. If that does not produce, switch depth or speed before changing the pattern entirely.
The plan
Plan A
Start with Diawl Bach (12-14) — on the bob / top dropper — slow figure-of-eight retrieve. If that does not produce, switch depth or speed before changing the pattern entirely.
Plan B
A fry-imitating pattern stripped through the margins can save a blank in autumn.
Watch for
Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.
Bank
Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.

Trout fly box
A practical Walloon stillwater pack for Ardennes reservoirs and stocked lakes where stocking history, bank access and wind matter more than classic river drift-fishing. Small lures, buzzers, nymphs and simple streamers belong here.
