When
April–June
Where
Start with Minkie (6-10) — on the point. If that does not produce, switch depth or speed before changing the pattern entirely.
The plan
Plan A

Start with Minkie (6-10) — on the point. If that does not produce, switch depth or speed before changing the pattern entirely.

Plan B

Slow down everything. A booby on a fast-sinking line, left static, can pick up deep fish.

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

Bank fishing only (no boats), fly only. The granite-bowl water is clear and acidic and is stocked with brown trout. The exposed position means wind is a constant factor. Buzzer fishing from April; the reservoir's isolation gives genuine solitude. Managed by South West Lakes Trust.
