As a fly fishing guide and outdoor writer for over a decade, I’ve witnessed some incredible hatches, but few compare to the explosive energy of the Green River’s cicada hatch. It’s a spectacle that draws anglers from across the country, and for good reason. The sheer size of the cicadas, the aggressive takes, and the overall chaos make it a truly unforgettable experience. This guide will cover everything you need to know about cicada fly fishing on the Green River, from understanding the hatch to selecting the right cicada fly patterns and maximizing your success. We’ll focus on the Utah section of the Green, renowned for its consistent and prolific hatches.
Understanding the Green River Cicada Hatch
The Green River cicada hatch isn’t a single event; it’s a prolonged period, typically spanning from late July through September, peaking in August. Unlike mayfly or caddis hatches, which are often tied to specific weather conditions, the cicada emergence is more predictable, driven by the cicada life cycle. These large insects spend years underground as nymphs, then emerge as adults to mate and lay eggs. The Green River provides ideal habitat for these cicadas, and when they emerge, it’s a feeding frenzy for trout.
The hatch intensity varies year to year, influenced by factors like rainfall and temperature. However, the Green River consistently delivers a robust hatch, making it a prime destination for anglers seeking large trout on terrestrial patterns. The trout, particularly the browns, become almost exclusively focused on cicadas, often ignoring other food sources. This is where knowing your cicada fly patterns becomes crucial.
What Makes the Green River Special?
The Green River’s unique geology and flow regime contribute to its exceptional cicada hatch. The river flows through a canyon environment, creating a microclimate that supports a healthy cicada population. The consistent water temperatures and abundant vegetation along the banks provide ideal breeding grounds. According to the National Park Service, the Green River’s ecosystem is remarkably resilient, allowing it to support these large-scale insect emergences.
Essential Cicada Fly Patterns for the Green River
Choosing the right cicada fly patterns is paramount. While trout aren’t particularly discriminating during a cicada hatch, having a variety of patterns in different sizes and colors will increase your chances of success. Here’s a breakdown of the most effective flies:
- Foam Cicadas: These are incredibly buoyant and durable, perfect for fishing fast water or creating a realistic “buzz” on the surface.
- Rubber Legged Cicadas: The rubber legs add significant movement and attraction, mimicking the struggling cicada effectively.
- Deer Hair Cicadas: Traditional patterns that offer a more natural profile, ideal for slower water and picky fish.
- Turk’s Tarantula: While not a direct cicada imitation, this terrestrial pattern often works incredibly well during the hatch, especially in shaded areas.
- Chock-Straw Cicadas: These are a newer style of cicada pattern that have gained popularity for their realistic profile and durability.
Sizes: Cicadas range in size, so carry patterns from size 6 to size 12. Larger patterns (6-8) are best early in the hatch or during peak emergence, while smaller patterns (10-12) can be effective later in the season or when trout are targeting smaller cicadas. Color-wise, tan, brown, and olive are all effective, depending on the specific cicada species emerging.
Beyond the Cicada: Supporting Patterns
While cicadas dominate the trout’s attention, don’t completely abandon other terrestrial patterns. Ants, beetles, and hoppers can still be effective, especially in areas where cicadas are less concentrated. As the hatch begins to taper off, trout may become more receptive to these alternative food sources. REI Expert Advice recommends always having a selection of terrestrials in your fly box, even during a cicada hatch.
Techniques for Cicada Fly Fishing
Successfully fishing the Green River cicada hatch requires a slightly different approach than traditional trout fishing. Here’s what I’ve learned over the years:
- Presentation: Accuracy is key. Get your fly close to the bank, under overhanging vegetation, or near any structure where cicadas might fall.
- Retrieve: A slow, deliberate retrieve is often most effective. Let the fly drift naturally, occasionally imparting a slight twitch or pause to imitate a struggling cicada. Don’t be afraid to “pop” the fly occasionally to create a buzzing sound.
- Floatant: Use a generous amount of floatant to keep your fly riding high. Cicadas naturally float, and a sunken fly won’t attract attention.
- Leader & Tippet: Use a shorter leader (7-9 feet) and a heavier tippet (3X-4X) to help turn over larger flies and handle aggressive strikes.
- Strikes: Be prepared for explosive strikes! Trout often hit cicadas with force, so set the hook firmly.
Fishing Different Sections of the Green River
The Green River offers diverse fishing opportunities. The section below Flaming Gorge Dam is known for its consistent flows and large trout. Further downstream, the river becomes more technical, with riffles, runs, and pools. The USDA Forest Service provides detailed information on access points and regulations for different sections of the river.

Leave No Trace and River Etiquette
The Green River is a pristine resource, and it’s our responsibility to protect it. Always practice Leave No Trace principles: leavenotrace.org. Pack out all trash, stay on established trails, and respect wildlife. Be mindful of other anglers and avoid wading through their runs. Respect the river and its inhabitants, and future generations will be able to enjoy the incredible cicada fly fishing opportunities the Green River has to offer.
Planning Your Trip to the Green River
The Green River is a popular destination, so planning ahead is essential. Book lodging and guide services well in advance, especially during peak season. Check the river flows and weather conditions before your trip. Be prepared for changing conditions and pack accordingly. Consider hiring a local guide to maximize your success and learn more about the river’s unique ecosystem. The Green River cicada hatch is a truly special event, and with a little preparation, you can experience the thrill of catching large trout on these exciting terrestrial patterns. I hope this guide helps you plan an unforgettable fly fishing adventure!
