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
Good — water temperature is working for you, but time of day is the limiting factor today. Grayling feeds actively in cold water — peak winter sport.

About this water

Brown trout, grayling and rainbow — though the exact split by district carries only medium confidence; two of the six district pages returned empty species fields during research and weren't independently reconciled, so treat the per-district detail as provisional rather than settled.
