San Juan Worm - Chartreuse

The San Juan Worm – Chartreuse is a high-visibility twist on a classic pattern, ideal for attracting trout in stained water, deep runs, or after spring runoff. Its bright, almost fluorescent body color draws immediate attention and serves as both a natural annelid imitation and a bold attractor fly when fish are aggressively feeding or visibility is poor. This is a go-to choice during high water, post-storm surges, or any time trout are keying in on drifting worms.

Tied with supple chartreuse chenille on a curved hook, this fly delivers natural movement while maintaining a simple, clean profile. The color stands out in low-light or off-color conditions, making it especially effective on tailwaters and freestone rivers alike.

To fish the San Juan Worm – Chartreuse effectively, drift it under an indicator along seams and through pockets, or use it as the anchor fly in a two-fly euro nymph setup. It's especially productive in early spring or during runoff when worms become dislodged and abundant in the drift.
