The Flathead River is 219 miles of free-flowing water in northwest Montana that spans an area from the Canadian border to the heart of the Bob Marshall Wilderness. The designated reaches of the Flathead includes the North, Middle, and South Forks of the river. These forks travel through some of the most wild, rugged country in the United States, including Glacier National Park, Great Bear Wilderness, and Bob Marshall Wilderness before joining near Hungry Horse to create the mainstem Flathead River, a major tributary to the Columbia River.
