How to fish it · for Grayling
When
Midday window — grayling feed best from late morning into early afternoon.
Where
Work runs and glides — grayling shoal in the bottom third of the water column.
Method
Tight-line nymph the bottom third with weighted patterns.
Kit
10 ft #3 rod, floating line, long leader to 4 lb fluoro for nymphs.
Why this works
Fair — water temperature is working for you, but time of day is the limiting factor today. Grayling feeds actively in cold water — peak winter sport.

What this classification means
WFD re-coded 2026-06-18: prior id PLRW200002141699 was a fabricated stub (no such code in EEA WISE). Re-mapped to PLRW200008214299 'Poprad' — Poprad is a single WFD river water body in Poland, so the match is unambiguous. Status: EEA WISE 2022 (3rd RBMP). Confidence: high.
