About this water
Water quality (WFD)
- Ecology: Moderate
- Chemical: Failing to achieve good
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 1 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 ATOK900790098 (High) described a different reach.

What would change the calculation
Warmer water — toward the 10–16 °C ideal band — would lift the temperature score.
The dawn and dusk windows score higher than the midday lull.

Seasons & zones
- Trout late July (after snowmelt clears) → 30 September
- Grayling 1 June → 31 December
Austrian grayling (Äsche) rules are state and fishery specific. Common pattern: closed 1 January – 31 May (spawning protection); open from June. Individual fishery seasons often end October/November. Always check the local Fischereikarte and specific water permit. Salzburg-area waters commonly show 1 June or 16 May opener.
Season dates are set at state or regional level — confirm the local rules.
