Cannon's Worm

The Cannon's Worm, designed by Jim Cannon, is a highly effective and simple fly pattern known for its ability to entice strikes from trout, particularly when they are feeding on worms in the water. Jim Cannon, a signature tyer, developed this pattern to mimic the appearance of a worm drifting along the bottom of streams, making it an ideal choice for use in high-water conditions or when fish are focused on worms. The fly's simplicity belies its effectiveness—often fished in low, slow-moving sections of rivers, the Cannon's Worm is particularly potent in the post-runoff period when worms are flushed into the water

Use After Heavy Rainfall: Worms are often washed into streams following rainfall or runoff. The Cannon’s Worm is highly effective during these periods, when fish are more likely to feed on worms. Fish the fly in slower, deeper pools where worms tend to collect and drift naturally.
