How to fish it · for Arctic 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 working for you, but insect activity is the limiting factor today. Grayling is active in the cooler margins of the season.
Likely species
Mayflies
