The Blackfoot River in Idaho is a premium fishing destination known for its native Yellowstone cutthroat trout fishery. This 133-mile river begins at the junction of Lanes and Diamond creeks at the eastern edge of the Blackfoot Wildlife Management Area and continues through Bingham and Caribou counties before joining the Snake River. The first seven miles of the river flow through the WMA, offering exceptional fishing opportunities in a diverse landscape of sagebrush steppe, wet meadows, lodgepole pine forests, and riparian habitats. Once considered a trophy fishery where 5-pound cutthroat catches were common, the Blackfoot River continues to be actively managed to restore its native fishery through habitat improvements and conservation efforts.
