NymphJorgensen's Jiggy Mysis
The Jiggy Mysis is a great fly for tail water turbulence below dams. It gets down fast and has lots of flowing materials to attract the biggest dam fish! This jig-style pattern is designed by AJ Jorgensen specifically for fishing tailwater environments where mysis shrimp are a primary food source. The offset bead head and flowing materials create an enticing action in the water.

Overview
This jig-style mysis pattern features an offset bead head that helps it ride hook-point up, reducing snags on the bottom. The white coloration mimics the translucent appearance of mysis shrimp, while the berry-colored thorax adds a subtle flash and color accent. The CDC collar provides lifelike movement in the water. Maxima Chameleon leader material is used to create realistic eyes. This fly is specifically designed for tailwater fisheries where mysis shrimp are abundant and trout feed on them heavily.

Fish with a dead drift near the bottom in tailwater environments. The jig hook design helps it ride hook-point up and bounce along the bottom. Works well with indicator or Euro nymphing techniques.
When to Use
Ideal for tailwater fisheries below dams where mysis shrimp are present. Most effective in deeper runs and channels.
Water Type
Designed specifically for moving water in tailwater environments with strong flows and deeper pockets.
Rigging Suggestions
Can be fished as a single fly or as part of a tandem nymph rig. Works well on a Euro nymphing leader.
Visibility & Floatation
