Coch Hwyad sits up in the hills above Llanbrynmair, on ground the small local association has fished quietly for generations without much need to advertise the fact.

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

Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.

Bank

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

About this water

Coch Hwyad sits up in the hills above Llanbrynmair, on ground the small local association has fished quietly for generations without much need to advertise the fact. Wild brown trout, upper Twymyn water, the kind of lake that barely registers outside the immediate valley and doesn't seem to mind. There's no boat, no stocking programme, no ticket booth with a laminated price list — just a club that knows its own water and members who'd probably rather you didn't make too much noise about it. If you can find someone to point you at it, and get permission sorted, it's an honest hill lake doing exactly what it's always done.
