Head to
Wind driftS wind
Northern end

A southerly has held for 7 hours at much the same temperature as the 12°C water. No thermal steer either way, but the drift still stacks food against the northern 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.

How to fish it · for Trout
When
Late April–June; evening rises through summer
Where
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.
The plan
Plan A

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.

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.

Bank

Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.

About this water

Craig-y-Pistyll sits in the northern Plynlimon foothills above Talybont — twelve hectares reached by forestry track, lightly fished, with about a mile and a half of bank to walk. Wild brown trout, small but vividly marked in the way upland fish often are. The walk in keeps the pressure off; on a still summer evening you'll have it to yourself and the curlew.
