Salmonflies/Stoneflies

How to Fish Salmonfly & Stonefly Hatches

Salmonfly and stonefly hatches create some of the most aggressive surface feeding of the year. Trout key on large insects and often hold tight to banks, structure, and fast water.

• Fish large dry flies tight to banks, rocks, and overhanging vegetation
• Cover water quickly—trout will move to strike big patterns
• Use nymphs before and after the hatch when fish are feeding subsurface

When Salmonfly & Stonefly Hatches Occur

These hatches are driven by water temperature and typically occur over a short but intense window.

• Most common from late spring to early summer
• Often move upstream as water warms
• Peak activity can vary by river and elevation

Fly Selection Tips for Salmonfly & Stoneflies

Size and visibility are critical during stonefly hatches, as trout are focused on large, high-calorie insects.

• Use larger flies (sizes 4–10) to match the hatch
• High-floating patterns improve drift and visibility
• Attractor patterns like Stimulators and Chubbies are highly effective

Stonefly Fly Quality & Construction

• Hooks: Heavy wire, chemically sharpened for strong hook sets
• Materials: Durable foam, rubber legs, and buoyant hackle for flotation
• Profiles: Designed to match large stonefly silhouettes
• Tested: Proven on Western rivers during peak hatch conditions
