Umpqua Slow Water Sally

The Umpqua Slow Water Sally is a popular and highly effective dry fly pattern specifically designed to imitate the adult Yellow Sally (Isoperla) stonefly, which is a common summer hatch. This pattern is distinguished by its slim profile, low-floating design, and often a high-vis post, making it ideal for targeting selective trout on smooth, slower currents, tailouts, or spring creeks. Because the natural Yellow Sally adult sits close to the surface, this fly is best fished with a quiet presentation and a dead drift to mimic the vulnerable insect.
