Ninety percent, right?
Trout feed below the surface ninety percent of the time. It sounds like somebody just made that number up, but it also seems about right. Well-tied nymphs are fish catching machines. And stoneflies are the perfect trout meal. With a two-year life cycle, both juveniles and adults are always available for trout snacking. And big trout are a little more willing to move for a bigger lunch (sometimes).
So take your flies down to the fish. Feed ’em stones. Get down. Go under.
