The San Juan Wire Worm Chartreuse is a durable, ultra-visible worm imitation built to excel in fast water, deep seams, and stained river conditions. Unlike traditional chenille-based San Juan Worms, this variation uses colored wire to create a slim, segmented body that holds its shape and sinks faster, making it ideal for euro nymphing or indicator rigs in high-pressure or high-flow scenarios.

The chartreuse color acts as a bold attractor, standing out in turbid water and triggering reaction strikes from trout, especially during runoff or post-rain periods when aquatic worms are washed into the current. The wire body adds weight and sheen while maintaining a natural worm-like movement as it bounces along the bottom.

To fish the San Juan Wire Worm Chartreuse effectively, use it as the anchor fly in a two-nymph rig or drift it solo under an indicator in heavy seams, riffles, or pools. It pairs well with more subtle droppers and shines when trout are holding deep and feeding opportunistically.
