About this water
Water quality (WFD)
- Ecology: Poor
- 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 4 m from the venue pin). Status: WISE 2022 (3rd RBMP) ecological class 4 = Poor, chemical 'failing to achieve good' (Austria-wide in the 2022 cycle).

Seasons & zones
- Trout 1 June → 30 September
- Grayling 1 July → 31 August
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. This ultra-high-altitude tributary has a very compressed grayling window.
Season dates are set at state or regional level — confirm the local rules.
