A classic mayfly nymph imitation with proven effectiveness, the BH Hendrickson is designed to match lighter-toned mayflies commonly found in Eastern Sierra rivers. Its natural profile and coloration closely resemble emerging mayfly nymphs, while the bead head ensures it gets down quickly and stays in the strike zone where trout are actively feeding.
This pattern is especially effective on rivers like the Upper Owens River, Lower Owens River, and Hot Creek during mayfly activity, when trout key in on drifting nymphs below the surface. Fish it as part of a Euro setup for tight control or under an indicator paired with a lighter dropper to cover multiple depths.
Best Uses:
Euro / tight-line nymphing
Indicator rigs in riffles, seams, and runs
Spring through early summer mayfly activity
Target: Trout feeding on mayfly nymphs in Eastern Sierra rivers
