Yellowstone River

This diverse fishery offers a wide range of experiences as it flows from its source at Yellowstone Lake northward through Hayden Valley and the Grand Canyon of the Yellowstone. Its character varies dramatically along its length, influencing the fishing opportunities. 

Yellowstone Lake itself offers fishing for native Yellowstone Lake Cutthroat Trout. Fishing from boats or along the shoreline is common here. The outlet of the lake forms the Yellowstone River, and this upper section, flowing towards the Upper Falls, is closed to fishing to protect spawning cutthroat trout. Below the outlet closure, the Yellowstone River meanders through Hayden Valley, characterized by slower currents, expansive meadows, and abundant wildlife. This section is renowned for its Yellowstone Cutthroat Trout fishing. Anglers often wade fish here, targeting rising trout with dry flies that imitate the prolific hatches of mayflies, caddisflies, and midges. Terrestrial patterns like grasshoppers can also be very effective, especially later in the season. The scenery in Hayden Valley is spectacular, with bison and other wildlife frequently visible. 

The river plunges over the Upper and Lower Falls of the Yellowstone, creating a dramatic and inaccessible stretch for fishing. Below the Lower Falls, the river flows through a steep-walled canyon. While some trails lead to the river in the canyon, access can be challenging, and fishing here is less common but can yield Cutthroat Trout in the deeper pools. 

Further downstream, below the canyon, the Yellowstone River receives significant tributaries like Slough Creek and the Lamar River, both famous for their exceptional trout fishing.
