About the flathead river

The Flathead River is a 158-mile-long river located in western Montana, USA. The river has a rich history, having been inhabited by Native American tribes for centuries. It was also a major transportation route for fur traders in the 1800s. The river's hydrology is largely influenced by the surrounding mountains and glaciers, resulting in a steady flow of cold, clean water. The river is home to several reservoirs and dams, including the Kerr Dam and Hungry Horse Dam, which provide hydroelectric power and irrigation water for nearby agricultural communities. Recreational activities such as fishing, hiking, and rafting are popular along the river, which is known for its scenic beauty and abundant wildlife.
