About the North Fork Shoshone River
The North Fork of the Shoshone River drains seven hundred square miles of the Absaroka Range and runs fifty miles east from the east gate of Yellowstone National Park to Buffalo Bill Reservoir above Cody. The Wapiti Valley it flows through is one of the more dramatic settings for a trout river anywhere in the country, with volcanic spires standing over both banks the whole way. The gauge at Wapiti sits roughly in the middle of the fishable river.
This is classic freestone water. It runs fast, cold and clear outside of runoff, with long riffles, boulder gardens and deep corner pools, and it is best fished by wading rather than floating through most of its length. The trout are a mix. Cutthroat and cuttbow hybrids dominate the upper river nearer the park boundary, rainbows and browns become more common as the river drops toward the reservoir, and brook trout hold in the colder side streams. Mountain whitefish are abundant throughout and often outnumber the trout in the deeper runs.
Timing is the main thing to get right. Snowmelt off the Absarokas puts the river out of shape from late May well into July in most years, and the fishing season effectively begins when it drops and clears. From then until October the North Fork is a dependable dry fly river, with golden stoneflies and caddis early, terrestrials through the summer, and blue-winged olives on the cold grey days of autumn.
The valley is public land for much of its length, with a string of Shoshone National Forest campgrounds and lodges along the highway providing straightforward access. Grizzly bears use this corridor heavily, and anglers walking the brushy bank are expected to carry spray and make noise. Cody, half an hour downstream, is the outfitting town for the whole drainage.
