Flathead River


  • River
Coursing the western boundary of Glacier National Park, Montana, this is a noted spawning stream for kokanee salmon. The Flathead River, in the northwestern part of Montana, originates in the Rocky Mountains near Glacier National Park and flows southwest into Flathead Lake, then after a journey of 158 miles (254 km), empties into the Clark Fork. The river is part of the Columbia River drainage basin, as the Clark Fork is a tributary of the Pend Oreille River, a Columbia River tributary. The river is a Class I river in Montana for purposes of recreational access. All of the headwaters forks are entirely or in part designated National Wild and Scenic Rivers.
