How to fish it · for rainbow trout
When
Conditions are not ideal but fishable at Siblyback Lake.
Where
Start with Blob (8-10) on a fast strip on floating line or static on sinking. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely.

The plan
Plan A
Start with Blob (8-10) on a fast strip on floating line or static on sinking. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely.
Plan B
If fish refuse on top, drop to a buzzer under an indicator at different depths.
Watch for
Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.
Bank, sheltered shores
In wind, bank fish the lee shore — boats can anchor in productive areas if conditions allow.

About this water
A Bodmin Moor reservoir at the edge of the moor, smaller and more sheltered than Colliford but with genuine upland character — clear granite-filtered water, a population of resident wild browns alongside the stocked rainbows, and a landscape that rewards the visit as much as the fishing. May and June bring a reliable beetle fall onto the surface; pre-book a Coulam boat by 3pm the day before to cover the drift lines the bank can't reach. Stocked and managed by South West Lakes Trust.
