About the Copper John Trout Fly

The Copper John is a simple pattern that has become a classic that brings fish to the net regularly on a diversity of waters such as English Chalk Streams, waters throughout the Sierras and Alaskan Creeks.

It imitates or suggests a wide range of larvae/ aquatic insects, especially when tied with the appropriate coloured wire.

It can be fished either singly or as a dropper of a terrestrial or a bushy dry fly.

It is ideal for those bottom hugging winter Grayling.

Expert Tip:

Copper John is dressed to sink like a stone, rapidly descending to where the shy and big fish feed. It is dressed with sufficient flash to attract and stimulate the trout's interest.

Creator of this trout fly: John Barr

This trout fly is designed to be fished on Dams & Reservoirs, Rivers & Streams, Still Water
