Stone Creek™ BH 20 Incher Stonefly Nymph
The Stone Creek™ BH 20 Incher Stonefly Nymph is a proven large-profile stonefly pattern designed to imitate the oversized stonefly nymphs that trout actively target throughout the year. Featuring a realistic segmented body, active rubber legs, and a weighted bead head, this fly delivers the lifelike movement and sink rate needed to consistently reach fish holding near the bottom.
Originally popularized during major stonefly and salmonfly hatches, the 20 Incher has become a year-round producer in rivers, freestone streams, and tailwaters where trout key on large aquatic insects. Its buggy profile and substantial silhouette make it an excellent searching pattern, especially in fast currents, deep runs, pocket water, and rocky structure.

FAQ
What makes the BH 20 Incher Stonefly Nymph effective in fast currents?
The active rubber legs provide natural movement and the weighted bead head ensures a steady sink rate, allowing the fly to stay near the bottom and remain visible to trout in fast-moving water.
Can this fly be used in deep runs and pocket water?
Yes, its substantial silhouette and sink rate make it particularly effective in deep runs and pocket water where trout hold near rocky structure.
Is the 20 Incher pattern suitable for year-round use?
Yes, while originally developed for stonefly and salmonfly hatches, it has proven effective year-round in rivers, freestone streams, and tailwaters.

This fly performs well in fast currents. The rubber legs move naturally and the weighted head keeps it down. I’ve used it in deep runs and pocket water with good results. Trout are consistently taking it.
Victoria Reid –
A solid choice for bottom fishing. The size and profile match what trout are targeting. It sinks well and stays in place. A bit heavy for some situations, but effective when needed.
Angela Paterson –
Great for rocky streams. The lifelike movement from the legs draws attention. I’ve used it during both spring and fall hatches and it’s been productive.
Zoe Brown –
Works well in tailwaters. The sink rate is consistent and the fly holds its shape. A bit bulky, but it’s noticeable to fish in deep water.
Sebastian Underwood –
Used it in a fast river and it stayed on the bottom. Trout were actively feeding on it. The design is realistic and the movement is convincing.
