How to fish it · for Trout
When
May–September
Where
Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
The plan
Plan A

Work a bushy searching pattern on the bob and drop a contrasting 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.

Bank

Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.

What this classification means

WFD code removed 2026-06-18: this alpine lake was incorrectly sharing the Doller river's code FRCR53 (and showing the river's status). EEA WISE has no dedicated lake (LW) water body for Lac des Perches, so status is left Unknown. Source: discodata.eea.europa.eu. | Prior note: WFD ecological status Moderate → Good corrected to EEA WISE 2022 (3rd RBMP) classification for waterbody FRCR53 (was a stale earlier-cycle value). Source: EEA WISE SWB_SurfaceWaterBody (discodata.eea.europa.eu), verified 2026-06-18.

Why this score
  • Wind conditions (windy) are not ideal for this water.
  • Daddy longlegs are in their seasonal window, boosting the chance of targeted feeding.
