Llyn Blaenmelindwr

View across Llyn Blaenmelindwr from the fishermen's car park, with forestry on Mynydd March beyond

Blaenmelindwr is the roadside one — fifteen hectares of upland water on the Plynlimon foothills above Ponterwyd, a good head of wild brown trout with the odd trickle-stocker pushing to a pound and a half.

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.

Boat — drift

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

About this water

Blaenmelindwr is the roadside one — fifteen hectares of upland water on the Plynlimon foothills above Ponterwyd, a good head of wild brown trout with the odd trickle-stocker pushing to a pound and a half. Heavy weed by late summer, which favours small dark patterns worked tight to the margin. Easy parking and easy access; the kind of water you can fish for a couple of hours on the drive back from somewhere else.
