Fly Patterns

Fly Patterns

Henry’s Fork is a fly fisherman’s paradise. The river is world-renowned for its diverse hatches and monster brown and rainbow trout. In order to effectively fish the Henry’s Fork, a properly selected fly pattern is essential.

At the start of the season, Mayfly, Caddis, and Stonefly hatches are abundant and can be found in large quantities throughout the river. During this time, it’s best to use small patterns such as the Parachute Adams, Elk Hair Caddis, and the Yellow Sally. These patterns are incredibly effective during the early season and can yield impressive catches.

As the season progresses, the river becomes saturated with larger insects such as Terrestrials and Hoppers. Though larger patterns are useful during the late season, fishing nymphs can prove to be even more productive. Popular nymphs fished during the summer months include: Prince Nymphs, Copper Johns, and Hare’s Ear Nymphs.

It’s important to remember that each section of Henry’s Fork varies in insect activity, water conditions, and other environmental factors. It’s best to pay close attention to the river and adjust your fly patterns accordingly to have the best chance for a successful outing.



Selecting the right tackle for your fishing needs is essential for a successful Henry’s Fork experience. Due to the diversity of fish species and size of the river, selecting the proper equipment can make or break your trip.

In general, selecting a medium-action rod and reel is best suited for fishing the Henry’s Fork. Wading is common in Henry’s Fork, so be sure to purchase waders or waterproof boots to protect against the river’s cold temperatures.

When selecting the proper leader and tippet, it’s best to use 9-foot leaders and 5X or 6X tippet, depending on the size of the fly you’re using. This will allow for the proper presentation of your fly and the ability to effectively land any fish you catch.

Lastly, the proper selection of flies is equally as important in selecting your tackle. Based on the flows and conditions, you might want to consider using a strike indicator or adding some weight to get your fly down in the water.



There are several techniques that can be employed when fishing Henry’s Fork, and it’s important to identify the right technique for the environment to maximize your success.

The first technique is the Dead-Drift. With this technique, the key is to mimic an insect’s natural flow with the river. Cast upstream and allow your fly to drift down the current, mimicking the natural flow of dead insects. This technique is best used during hatches and likely to land the most fish.

The second technique is the Swing Technique. With this technique, you will cast your fly downstream and allow it to swing with the current. Strikes typically come at this time. Using larger streamers, such as Woolly Buggers or Zonkers, is recommended when using this technique.

Lastly, the Nymphing technique is best utilized during periods of high pressure and low hatches. A well-placed nymph rig, targeted towards deep pockets or seams, can result in some of the largest fish caught in Henry’s Fork.

Above all, it’s important to keep in mind that Henry’s Fork is a complex aquatic ecosystem, and there is no single technique that reigns supreme. As an angler, it’s up to you to read the river and apply the technique best suited for your needs.
