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
Good — water temperature is working for you, but time of day is the limiting factor today. Grayling feeds actively in cold water — peak winter sport.

About this water
Water quality (WFD)
- Ecology: Moderate

What this classification means
WFD re-coded 2026-09-14 after the pin audit: matched by point query against EEA WISE WFD2022_SurfaceWaterBody (the river water body whose line lies 2 m from the venue pin). Status: WISE 2022 (3rd RBMP) ecological class 3 = Moderate potential (heavily modified water body), chemical 'failing to achieve good' (Austria-wide in the 2022 cycle). Prior id ATOK401750000 (Good) described a different reach.
