Question

FishGPT · Accepted Answer

Fishing the **Kenai River** in August can be quite the adventure, and choosing the right size and color for your **Copper John Nymph** can make all the difference in the world. The Copper John Nymph is a versatile fly that mimics a wide array of aquatic insects, and its bead head helps it sink quickly to the riverbed where the fish are feeding.

When it comes to the Kenai River during August, the water levels can vary, but it's generally a time when many fish species are active. The **sweet spot** for a Copper John Nymph is often a Size **14 or 16**. These sizes are small enough to imitate the natural nymphs found in the river but still substantial enough to attract attention.

As for color, the **traditional copper** color is a proven winner. However, considering the Kenai's clear waters and diverse fish population, variations like **red** or **olive** can also be highly effective. These colors stand out well against the riverbed and can trigger strikes from fish like **rainbow trout** and **Dolly Varden**. The red variant, in particular, can be quite effective as it mimics the appearance of many local aquatic insects.

A practical tip for fishing with the Copper John Nymph on the Kenai is to use it as a dropper fly. Pair it with a dry fly like an **Elk Hair Caddis** or a **Chubby Chernobyl** to cover different water columns. This technique not only increases your chances of a strike but also allows you to fish effectively in varying water depths and currents.
