Blackfoot River

About Blackfoot River

The Blackfoot River, a significant tributary of the Snake River in Idaho, originates northeast of Soda Springs in Caribou County and meanders approximately 133 miles before joining the Snake River southwest of Blackfoot in Bingham County. Its headwaters are nestled within the Caribou-Targhee National Forest, with the river flowing northwest, passing through the Blackfoot Reservoir, before continuing its westward journey. The Blackfoot River's drainage basin covers about 1,097 square miles, and its flow can be dynamic, averaging 210 cubic feet per second but subject to significant fluctuations, including periods of zero flow downstream of the reservoir. The lower sections are marked by unique basalt flows from the Blackfoot-Gem Valley lava field. As it approaches the Blackfoot Narrows, the landscape transforms into a desert canyon environment, characterized by sagebrush and juniper habitats, which also offers excellent birdwatching opportunities. Anglers will find the Blackfoot River is a well-regarded trout fishery, consistently stocked with Rainbow Trout, and also home to Cutthroat Trout and Mountain Whitefish. Surveys have also observed Brook Trout. The river supports robust insect activity, with common hatches of Blue Wing Olives and Caddisflies providing consistent opportunities throughout the season. Effective fly fishing tactics often involve nymphing along the riverbed, particularly in the canyon sections, and swinging flies can also yield good results. Access is varied, with public access points available, though reaching certain areas, like the Blackfoot Narrows, may require a bit more effort. Wading is a primary method of fishing for many anglers, and it's crucial to be aware of the river's flow, which can change considerably, especially downstream of the Blackfoot Reservoir.
