Wild brown trout and grayling respond to careful nymphing and precise sight fishing in the gin-clear current. In low water, the technical demands shift upward—this is where restraint and accuracy matter more than technique alone.

How to fish it · for Grayling
When
Midday window — grayling feed best from late morning into early afternoon.
Where
Work runs and glides — grayling shoal in the bottom third of the water column.
Method
Tight-line nymph the bottom third with weighted patterns.
Kit
10 ft #3 rod, floating line, long leader to 4 lb fluoro for nymphs.
Why this works
Excellent — water temperature is right today, though insect activity could be better. Grayling feeds actively in cold water — peak winter sport.

Status: WISE 2022 (3rd RBMP) ecological class 2 = Good, chemical 'failing to achieve good' (Austria-wide in the 2022 cycle). Prior id ATOK400980047N (Moderate) described a different reach.
