How to fish it · for Trout
When
May–September for trout; mayfly mid-May to early June
Where
Set up a broadside drift and cover the water systematically. Work Bibio on the bob and Murrough on the point.
The plan
Plan A

Set up a broadside drift and cover the water systematically. Work Bibio on the bob and Murrough 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.

What this classification means

WFD code normalized 2026-06-18: IE_SH_25_191a → IESH_25_191A (EPA national format → EEA WISE euSurfaceWaterBodyCode; same water body, now joinable to WISE). Status confirmed against EEA WISE 2022 (3rd RBMP). Source: discodata.eea.europa.eu. | Prior note: EPA WFD 2019-2024 (lake layer) — Lough Derg: Moderate ecological status. Re-tagged 2026-06-18 from IESH_25Y020200 (a river/stream water body, not the lough) to the lough's own EPA lake water body. Source: EPA Ireland WFD 2019-2024 classification (catchments.ie / EDEN).

Why this score
  • Wind conditions (ripple) are not ideal for this water.
  • Cloud cover (mixed) suits the fishery well.
  • Buzzer is in its seasonal window, boosting the chance of targeted feeding.
