Kaufman's Stonefly nymph

The Kaufmann's Stone, developed by legendary tier Randall Kaufmann, is one of the most iconic stonefly nymph patterns ever created. Designed to imitate the nymphs of large stoneflies such as The Salmonfly & Golden Stone, Kaufmann's pattern became a benchmark for stonefly imitations in the 20th century. Known for its heavy profile, lifelike movement, and durability, this fly quickly earned a reputation among anglers targeting trout in fast-moving Western rivers. Kaufmann’s use of lead wire and natural materials made the fly highly effective at getting to the bottom

Fish It During High Noon: While stoneflies are often associated with early morning or evening, their nymphs are most active during midday in cold, clear waters. Trout actively key in on them at these times, especially in tailwaters or spring creeks. Focus on deep, sunlit seams where light penetration triggers stonefly movement.
