San Juan Worm

The San Juan Worm is a simple yet highly effective fly pattern that originated in New Mexico’s San Juan River, a tailwater known for its abundance of aquatic worms. This fly mimics aquatic annelids, particularly red or pink bloodworms, a staple in the diets of trout in nutrient-rich waters. Its straightforward design—typically a chenille body tied on a hook—has made it a go-to fly for high-pressure fisheries, muddy conditions, or when other patterns fail. Its versatility lies in its ability to be fished in various water depths and conditions, appealing to both novice and seasoned anglers.

Fish the San Juan Worm under an indicator or as part of a two-fly rig, allowing it to drift naturally near the bottom where fish are feeding. It’s particularly effective in high or off-colored water conditions. Adjust weight and leader length to match water depth and current speed. Experiment with colors like red, pink, tan, and chartreuse to match the conditions and fish preferences.
