    Hendrickson Nymph

    #14#16#18

    Hendricksons are a key early spring hatch in this region; fishing a nymph imitation subsurface targets actively drifting nymphs, a primary food source for Brook Trout and Atlantic Salmon.

    dry80%

    March Brown

    #10#12#14

    While higher flows might limit consistent dry fly action, a March Brown adult imitation can be effective for opportunistic Brook Trout and Atlantic Salmon rising in softer eddies during this early spring hatch.

    Elk Hair Caddis (CDC)

    #14#16#18#20

    Caddis are a consistent food source throughout the summer months on freestone rivers like the Pleasant, making this a reliable dry fly.
