About this water

The Deutsche Traun — flagship Bavarian trout and grayling river. Among the few Bavarian rivers where brown trout, rainbow trout and grayling still reproduce naturally. The Hochberg stretch is crystal-clear holding trout and grayling in premium alpine-river water. Established beat-style management with strong fish stocks. Excellent nymphing and dry fly with good hatches. Clear limestone water flowing from the Chiemsee lake district.

  • Grayling1 May → 31 December

    Bavaria state rule: grayling (Äsche) closed 1 January – 30 April, minimum size 35 cm. Open season 1 May – 31 December. Individual fishery/Hegering may impose stricter rules or shorter access. Always check the specific permit (Fischereischein + Fischereiberechtigung). C&R recommended on classified trout/grayling waters.

  • Charvaries_by_region → varies_by_region

    Alpine char (Saibling) — not a primary species on the Traun but may occur in cold upstream sections. Seasons and regulations are set by Bavaria's fishing authority (Fischereibehörde) and local water rights (Hegering/club). Verify char presence and regulations locally before targeting.
