Directions
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 pocket water has an extremely compressed grayling window.
Season dates are set at state or regional level — confirm the local rules.
