Scud / ShrimpCharlie's Mysis Shrimp
A highly effective pattern for tailwaters where mysis shrimp are present, especially below bottom-release dams. Charlie's Mysis Shrimp imitates the translucent, drifting crustaceans that are a key food source for trophy trout. Its sparse, realistic design and subtle movement make it deadly in clear, cold water.

Overview
This pattern is tied with simplicity and effectiveness in mind. A base of white egg yarn or Estaz forms the milky, translucent body, mimicking the profile of a live or dead mysis shrimp. Small black rubber legs are tied in as eyes, and a short tail of marabou or ostrich herl adds subtle movement. The thorax can be bulked slightly with egg yarn or CDC for a fuller silhouette.
