Jiggy Diamond Leech

A Tungsten Jig Leech with Flash and Movement

The Jiggy Diamond Leech is a tungsten bead jigged leech imitation that combines the fast-sinking, point-up advantage of a jig hook with a diamond braid body that creates a pulsing, iridescent flash profile in the water column. Leeches are one of the most overlooked but highly effective food sources for large trout in Colorado's rivers — they're present year-round, they move with a distinctive undulating action, and big trout actively hunt them along the bottom of deep runs, pools, and slow-moving water.

The diamond braid body creates a multi-tonal shimmer that imitates the natural iridescence of a leech in motion, while the tungsten jig bead gets the fly to depth fast and keeps it riding point-up through the drift for fewer snags and better hookup rates. At size #8, this is a substantial pattern that creates real presence in the water — ideal for targeting larger, predatory trout that are looking for a bigger meal. On the Roaring Fork, Frying Pan, and Colorado River, this pattern is especially effective in slower, deeper water where leeches are most active.

Pattern Details

• Style: Jigged tungsten bead leech imitation
• Body: Diamond braid — pulsing, iridescent flash profile
• Size: #8 — substantial leech profile for larger, predatory trout
• Bead: Tungsten jig bead — fast sink rate, rides hook point-up
• Hook: Jig hook — reduces snags, improves hookups
• Imitates leeches — a year-round food source for large trout
• Effective on the Roaring Fork, Frying Pan, Colorado River, and most Colorado rivers
• Best in slower, deeper water where leeches are most active

How to Fish It

Dead-drift on a tight line or under an indicator through deep runs, pools, and slow-moving water where leeches are most active. Also effective with a slow, hand-twist retrieve or a gentle strip-pause that imitates the undulating movement of a swimming leech. The tungsten jig bead keeps the fly in the strike zone along the bottom throughout the drift. Fish it as a single fly or as the point fly in a two-fly nymph rig with a smaller midge or emerger as a dropper.
