Overview of Location

The Henry’s Fork is a favorite for fly fishermen, as the fishing here becomes unparalleled as the tributaries feed the waters. Originating at Henry’s Lake south of the Montana border, it flows through Big Springs and Island Park, with a number of places to access great spots.

Type of waterway

With almost 100 miles of varied water, a fly fisherman can spend days on the Henry’s Fork and never fish the same spot. Wading is good in most places, although floating is the best in some areas, notably in the Box Canyon stretch.

Fishing seasons

Although fishing season is open from Memorial Day to the end of November, the best times to do your angling are from April to June. During April and May, a great place to go is below Ashton Dam. In June, Henry’s Fork offers up prolific Salmonfly hatches taking place in Box Canyon at Island Park.

Most common fish species

The most common fish caught in the Henry’s Fork are cutthroat, rainbow and brook trout.

Popular fishing areas

One of the most popular sections to fish is below the Island Park Reservoir. At the spot where the Buffalo River joins up with the Henry’s Fork (the beginning of the Box Canyon), you’ll find huge trout. This section stretches for about 3 miles through the canyon, and provides excellent and “easy” fishing.

Once leaving Box Canyon, the river slows and widens, taking on the characteristics of a large creek. There are a number of pockets and pools, and the challenges present themselves. But it’s all worth the effort. For seven miles, past Last Chance and into Harriman State Park, this gently meandering water provides an abundance of big rainbows.

For the best spots, and the best catches, it’s often in your interest to hire a fishing guide. Their experience can lead you to terrific results, and make your fishing trip the best ever.
