How to fish it · for brown trout
When
The buzzer is on. Sedge may also come into play as the day warms. Strong wind will make open-water drifting difficult. Look for sheltered bays and lee shores.
Where
With limited drift, anchor or fish static from sheltered positions. Work Pheasant Tail Nymph on the bob and Diawl Bach on the point.

Plan A · Plan B · what to watch · bank or boat
The plan
Plan A
With limited drift, anchor or fish static from sheltered positions. Work Pheasant Tail Nymph on the bob and Diawl Bach 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
Watch for Sedge towards evening — this could be the best window of the day.
Bank, sheltered shores
Strong wind makes boat fishing difficult — sheltered bank spots near lee shores will fish best.

About this water
Padarn is one of the largest natural lakes in Wales — ninety-seven hectares of moraine-dammed glacial water below the Llanberis Pass, twenty-nine metres at its deepest. Wild brown trout in the margins; torgoch — Arctic char — in the deep water, where they've held since the last glaciation. A boat helps. The view down the lake with Snowdon behind is the kind that justifies a long drive even on a day the fishing doesn't quite happen.
