Lake of the Greycheek — sometimes called Lake Australia for its outline on the map — in a high Glyderau cwm below Tryfan and Glyder Fach, five hundred and fifty-five metres up. Four hectares with weedy margins and no clear path round it, holding hard-fighting wild brown trout to half a pound. Forty minutes' walk from the Ogwen Cottage car park; popular with walkers, less so with anglers.

How to fish it · for brown trout
When
Late April–June; evening rises through summer
Where
Work Gold-ribbed Hare's Ear on the bob and Pheasant Tail Nymph on the point.
Today's tactical plan
The plan
Plan A · Plan B · what to watch · bank or boat
The plan
Plan A
Work Gold-ribbed Hare's Ear on the bob and Pheasant Tail 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 — at anchor
Windy conditions suit anchoring in productive areas rather than open-water drifting.
