Fishing Tips

Season

This fly is particularly effective in late spring to early summer during stonefly hatches.

Presentation

The Kaufmann Stone is best fished in deep, fast-moving water. Use a dead drift technique and allow the fly to bounce along the bottom.

When to Use

Use this fly when you know stoneflies are present in the water you're fishing. It's also a good choice when nothing else seems to be working, due to its large profile and enticing movement.

Water Type

Kaufmann Stone is highly effective in moving water, particularly in rivers and streams with stonefly populations.

Rigging Suggestions

Use a high-density, fast-sinking line to get the fly down quickly. Heavier tippets can be used due to the typically larger size of this fly.

Visibility & Floatation

This fly sinks quickly and stays submerged, making it visible to fish in the water column. The rubber legs add movement and visual appeal.
