Fly Fishing on the North Tongue

Where to Fly Fish on the North Tongue River Wyoming (Maps, Flies and Technique)

Wyoming and fly fishing are a perfect pair. While most anglers think of the western part of the state when it comes to fly fishing, the Bighorn Mountains in north central Wyoming should not be ignored! They’re home to hundreds of miles of high-quality trout water. The North Tongue River, a branch of the Tongue River, is perhaps the most productive of all the water in the Bighorns. It’s a picturesque fishery with all the perfect challenges you need for quality days on the water.

A Little Bit About the North Tongue River

The Tongue River begins in the Bighorn Mountains and flows Northeast for nearly 250 miles. It eventually flows into the Yellowstone River near Miles City, Montana. The “North Tongue” portion is around 10 miles long until it eventually connects with the South Tongue and they both create the Tongue River!

Easy Access off of State Highway 14

As you’re passing through the Bighorn Mountains, you only have a couple roads to travel! One of those is State Highway 14. The North Tongue flows along the highway and the Wyoming Fish and Game Department has created multiple access along it. This specific access point is a few miles west of the Bear Lake Lodge. Here, you’re going to find taller willow bushes, but several eddies and deep pools. The fishing is going to be technical, so make sure your casts are well-practiced, so you can be as accurate as possible.

Burgess Picnic Site

The Burgess Picnic Site is a perfect spot to begin your day of fishing. Located near the North Tongue Campground, you have a nice starting point with several miles of fishable water in both directions. If you head west along the river, you’ll find a nice amount of seclusion! The water is fairly calm with tight eddies and surprisingly deep water. Dry dropper patterns are your best bet through this section.

If you head east, you’ll find more boulders and pocket water. This is a fun part of the North Tongue to fish! Most anglers stick to the calmer water that the North Tongue provides, so you have a unique opportunity to fish in lightly pressured water. Walking along the banks is your best bet because wet wading can be a challenge in the faster moving water.

Quiet Fishing Access off of Highway 14

As you drive along the river along Highway 14, you’ll be able to take a look at sections and determine whether or not you want to fish them. This section in the shadow of Hunt Mountain is a little lesser-known area that takes a small hike to reach from the road. Fishhook Creek enters the North Tongue here, so follow the creek down towards the river, and you’ll be okay.

There are multiple deep pools here that hold fish nearing 20 inches. They can be spooky due to the clear water, but with some effort, you’ll find that they’re willing to take your flies! Don’t be overly worried about running into anyone here. You may get another angler curious about whether or not you’re landing anything, but hiking up or downstream will give you more freedom.

Why the North Tongue is Perfect for Fly Fishing?

The North Tongue is perfect for fly fishing because it’s all public, nestled deep in National Forest land and holds extremely large fish. It’s not uncommon to see fish over 20 inches in the deep pools and skinny water. The water is extremely cold, so the fish populations stay healthy.

Guide Pro Tip: Sometimes knowing the stocking numbers can give you a clue to where the trout populations. Most stocked trout are little 3 to 6 inchers but learning where can help. To help here’s a shortcut link the the Wyoming Fish Stocking Report

Continued stocking of brown and rainbow trout from the Wyoming Game and Fish Department ensures that the fishing is going to stay high quality for years to come.

You can camp along the river or stay at one of the lodges! It’s truly one of the most accessible rivers in the country.

What Stream Flow is Best for Fishing the North Tongue River

The water in the North Tongue River doesn’t flow very fast! Due to the smaller size of it, the runoff season can fill the river and make it unfishable, but the rest of the year is generally great! If possible, you want to fish this river at around 125 to 150 CFS. During a normal year, this is where it’s going to be for the summer and fall!
