How to fish it · for brown trout
When
Nymphing can work through most of the day.
Where
Cover mixed depths.
Method
Start with tight-line nymphs and adjust if fish rise or drift higher.
Kit
9 ft #4 rod, floating line, 12 ft tapered leader to 4–5 lb fluoro tippet.
Why this works
⚠️ Water at 18.3°C — above the brown trout caution line (18°C). Fish dawn or dusk only. Land it fast, wet hands, no air shots. Otherwise poor — water clarity is in the right range.

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. Multiple sources point to this as one of the safest German rivers to include with confidence. Excellent nymphing and dry fly with good hatches. Clear limestone water flowing from the Chiemsee lake district.
