The Blackfoot River, located in western Montana, is a 137-mile long river that has played a significant role in the history of the region. The river was named after the Blackfoot Nation, a group of indigenous people who once inhabited the area. The Blackfoot River is a tributary of the Clark Fork River, which eventually flows into the Columbia River.

The river is fed by snowmelt and has a peak flow in late May and early June. The river's hydrology is influenced by two major dams, the Thompson Falls Dam and the Noxon Rapids Dam, which create reservoirs that provide hydroelectric power to the region.

The Blackfoot River is a popular recreational destination, known for its trout fishing and scenic beauty. The river was made famous by the book and movie "A River Runs Through It". The surrounding land is also used for agriculture, primarily for ranching and hay production. The river and its surrounding area have been protected by federal and state agencies, including the creation of the Blackfoot-Clearwater Wildlife Management Area.
