A classic alpine trout and grayling box. Nymphs, dry flies and streamers all belong, with the season often starting later in alpine regions.
Lake-fed limestone water flowing through the Salzkammergut, holding trophy brown trout and grayling of genuine quality. The Gmundner Traun below Traunsee is the working section—a bucket-list river where careful nymphing and selective dry fly work pay dividends.
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 3 m from the venue pin). Status: WISE 2022 (3rd RBMP) ecological class 3 = Moderate, chemical 'failing to achieve good' (Austria-wide in the 2022 cycle). Prior id ATOK402210000 (Moderate) described a different reach.
