How to fish it · for Grayling
When
June through autumn, once the January-May closed season lifts. The gravel runs between the granite pools suit them well.
Where
Riffle heads and the faster gravel water between the deeper pools — they sit higher and further out than the trout.
Method
Euro-nymph as the default approach; dries when a hatch shows through the afternoon.
Kit
10 ft #3 nymphing rod, 4-5 lb fluoro; 9 ft #4 for dries. 12 ft leader.
Why this works
Fair — time of day is working for you, but water temperature is the limiting factor today.
