How to Fish a Copper John: A Comprehensive Guide

The Copper John is a versatile and effective fly pattern that every angler should have in their tackle box. Developed by legendary fly tier John Barr, this nymph imitates various aquatic insects, making it suitable for a wide range of fishing conditions. Whether you’re a beginner or an experienced angler, learning how to fish a Copper John can greatly enhance your chances of success on the water. In this article, we will provide you with a step-by-step guide on how to fish this fly, along with answers to frequently asked questions.

Step 1: Understand the Copper John

The Copper John is primarily used as a nymph pattern, mimicking mayflies, caddisflies, and stoneflies. It features a tungsten bead head, copper wire body, and rubber legs. The bead head helps the fly sink quickly, while the copper wire body adds weight and imitates the segmented body of insects. The rubber legs provide lifelike movement, attracting fish.

Step 2: Choosing the Right Rod, Line, and Leader

For fishing a Copper John, a 9-foot, 5- or 6-weight fly rod is ideal. Pair it with a weight-forward floating line and a 9-foot tapered leader with a 4X to 6X tippet. This setup provides the necessary control and sensitivity to effectively fish the fly.

Step 3: Presenting the Fly

Cast the Copper John upstream or slightly across the current. Allow the fly to sink and drift naturally with the current. You can add small twitches or short strips to imitate the movement of a swimming insect. Be mindful of the depth and adjust your casting angle and weight accordingly.

Step 4: Detecting Strikes

Watch your fly line or indicator for any sudden movements, hesitations, or unusual behavior. Often, a subtle twitch or pause indicates a fish has taken the fly. Be ready to set the hook when you notice these signs.

Step 5: Hooking and Playing the Fish

When setting the hook, use a quick and firm strip of the line or a gentle lift of the rod tip. Maintain a steady pressure on the fish and let it run if needed. Avoid excessive force that may result in a broken line or lost fish.
