Slough Creek at Yellowstone
Like the North Platte, Slough Creek flows out of the Montana wilderness into Wyoming. This beautiful, fishable little river winds through Yellowstone National Park’s rugged Wyoming mountains for approximately 25 miles through jagged canyons and placid meadows before its confluence with the Lamar River. Indeed, many visitors come to Slough Creek only for its scenic beauty.

Slough Creek is an outstanding dry fly fishery. Cutthroat trout of over a foot in length are not uncommon (these are protected by catch and release regulations), and the lower reaches teem with rainbow trout.

There’s more to Slough Creek than excellent Wyoming fishing, however. The country around Slough Creek is picture perfect for hikers and backpackers. Another popular way to enjoy Slough Creek is on horseback. Indeed, the lack of roads in this primeval area means most anglers have to hoof it, one way or another, to get to the best spots.
