Wyoming, with its wide-open spaces and low population density, offers some of the most unspoiled and lightly fished streams in the American West. The state's rivers are steeped in the history of the American frontier, and many are in regions that have changed little since the days of early trappers and explorers.

Here's a table with details about the top fly fishing rivers in Wyoming, their historical context, the approximate number of fishable miles, the types of trout you can expect to find, and high and low estimates of fish counts per mile. Keep in mind that fish populations are dynamic and can vary from year to year due to environmental conditions, conservation efforts, and fish management practices.

Wyoming stands out as a premier destination for fly anglers due to its world-renowned rivers, abundant fish populations, and breathtaking natural settings. Let's delve into why Wyoming is an ideal place for fly fishing.

Fishing quality

Iconic rivers and streams. Wyoming is home to some of the most legendary fly fishing waters in the world, including portions of the Yellowstone River, the Snake River, and the North Platte. These waters are celebrated for their high-quality fly fishing. Oddly, the iconic rivers overshadow the unspoken creeks... shhhhh.
Abundant trout populations. The state is a haven for trout enthusiasts, with healthy populations of rainbow, brown, cutthroat (including the native Yellowstone cutthroat), and brook trout. The diversity of species offers a thrilling challenge to anglers of all skill levels.
Wilderness fishing. For those seeking solitude and a more rugged experience, Wyoming's vast wilderness areas, including the Wind River Range and the Absaroka-Beartooth Wilderness, provide remote streams and lakes where anglers can fish in tranquillity, often without seeing another soul for days. Wyoming is the real deal. Don't sleep on the remoteness — it is extremely common to get out in the middle of nowhere, so be prepared for the worst-case scenario in one of the country's most beautiful places.

Nature observation quality

Spectacular wildlife. While fly fishing in Wyoming, anglers might catch sight of bison, elk, moose, pronghorn, wolves, and even grizzly bears in some areas, especially in places like Yellowstone and Grand Teton National Parks.
Diverse ecosystems. The state's landscapes range from high deserts to alpine meadows, offering a variety of ecosystems to enjoy. Each supports unique plant and animal life, enriching the experience. The wind in Wyoming can be absolutely breathtaking, in that it sucks every bit of warmth and energy out of you. Don't be put off, though — if you're an early riser you can experience the calm and have incredible early morning fishing.
Conservation areas. Wyoming's commitment to conservation ensures that many areas are preserved in their natural state, providing pristine environments for both fish and anglers. The state's efforts to protect and improve these habitats mean many of the fishing areas remain some of the best in the world.

Statewide support

Fisheries management. The Wyoming Game and Fish Department actively manages the state's aquatic resources, including setting regulations that protect fish populations and habitats to ensure sustainable fishing for future generations.
Accessibility. There is ample public access to rivers, lakes, and streams, with the state providing numerous public fishing areas, boat launches, and stream access points. The one drawback is how much land is privately owned — these massive ranches can span hundreds of thousands of acres, so be aware of land usage regulations. More than anything, though, this is a misconception. Although there are swaths of private land, there is more than a lifetime of fly fishing opportunity in Wyoming.
Fishing resources and education. Wyoming offers a wealth of resources for anglers, including fishing reports, educational programs, and classes on fly fishing techniques and ethics, fostering a well-informed community of conservation-minded anglers.

Statistics on anglers visiting Wyoming

Wyoming might not have the same large population centres as some states, but its fly fishing draws enthusiasts from across the globe. Historically, Wyoming has seen a steady number of visiting anglers, and the Wyoming Game and Fish Department consistently sells a significant number of non-resident fishing licenses each year. The draw is often the quality of the experience, which can mean fewer anglers per mile of stream compared to more populous states.

The revenue generated from license sales, fishing tourism, and outdoor recreation contributes significantly to local and state economies, highlighting the importance of angling in Wyoming.

In summary, with its combination of legendary waters, abundant and diverse fish populations, stunning natural beauty, and strong support for sustainable fishing, Wyoming stands out as a top destination. It's a place where both the challenge of the sport and the serenity of nature can be found in abundance.

The data presented in the table are estimates, and actual fish counts vary. The fishable miles mentioned are not continuous and can be fragmented by impassable sections, private lands, or varying river conditions. These estimates also don't account for seasonal migrations, spawning cycles, or specific environmental regulations that may be in place. Anglers should consult local fishing reports and regulations for the latest information.

Fishing Wyoming with a guide

Wyoming is the state where a guide earns their fee twice over — once for the fishing, and once for knowing exactly where the public water ends. With ranches spanning hundreds of thousands of acres, access boundaries aren't always obvious from the bank. Our Certified Guides & Lodges are operations we know personally and stand behind.

Generalized packing list

When you visit Wyoming for fly fishing, here are a handful of items I recommend bringing with you so you can have a great trip.

Waders. Wet wading can happen in certain months, but waders are a must-have because of the weather fluctuation. The Whetstone II Chest Wader is a solid all-rounder, the Women's Whetstone is cut properly for women, and the MERIDIAN Z adds a front zip. Don't forget a wading belt.
Socks. Get good thin wool socks that will keep you warm and comfortable. The Minus33 Lightweight Over The Calf Wool Socks are exactly right — thin, so your foot has room and circulation can keep it warm.
Bottom layer. A nice thin layer keeps you warm and your bulk down during the day. The Chugach Zip-Off 3/4 Bottoms avoid bunching inside a boot, or go full length with the Midweight Wool Bottom.
Top layer. Thin layers give you a good base to stay cool and add to. The Midweight Wool Long Sleeve Crew or, for women, the Heavyweight Wool 1/4 Zip.
A proper wind layer. This matters more in Wyoming than anywhere else on this list. Wind is the defining condition, and it will strip heat out of you even on a mild day. The Whetstone Waterproof Wading Jacket blocks it, and the packable Frogg Toggs Cascades Pack Jacket lives in a bag for when it picks up.
Puffy jacket. During morning and evening these are clutch, and when a cold spell hits you're prepared. The Deckhand Puffy Jacket, or the warmer FORLOH ThermoNeutral Down Hooded Jacket.
Flies. Have a good assortment of basics and you'll be fine. The Postfly First Cast Beginner Trout Assortment is 30 flies covering the patterns that work almost anywhere, and the Fly Rod Chronicles Classic Trout 12pk rounds out a box nicely. Wind means bigger, more visible dries are often the practical choice — the Hopper Dropper Assortment earns its place here. Browse all fly pattern assortments.
Rod and reel. Bring your own or pick up a matched set. A slightly heavier rod helps against the wind. Here is a guide to selecting one, or go straight to the rod and reel combos.
Net. Netting by hand is fun and all, but a net takes the stress off. Since you're travelling, a compact one is the ticket — the Rising Brookie Net is short and fits in a bag easily, and the Lunker Net gives you more reach.
Wading boots. Don't mess around. The Slate Felt Sole Wading Boots grip slick rock well — just check Wyoming's current regulations on felt before you travel, since rules vary by state and change.
Fishing pack. A small pack is nice for a few extra layers based on weather, and for a camera. The JHFLYCO 27L Waterproof Backpack keeps everything dry, and a Deluxe Fishing Vest is the alternative if you'd rather have it all in front of you.
Safety kit. Given how remote Wyoming gets, this isn't optional. A Fiber Light EDC Fire Kit, a knife such as the Scout Feather Adventure Survival Knife, a headlamp, and water in an STLHD 32oz Oasis. Tell someone where you're going.
