Brown Trout fly box

The heartland of English dry fly fishing. Upstream dry fly and emerger presentation dominates. Nymphing restricted or discouraged on many beats. Gin-clear alkaline water, prolific weed growth, educated wild brown trout. Precise imitation and delicate presentation are paramount.
