Rapids in this guide are classified using the International River Scale of Difficulty. This float guide covers the North Fork of the Flathead River, the Middle Fork of the Flathead River and the South Fork of the Flathead River. The headwaters of the North Fork of the Flathead River originate in Canada. As the rivers flows south into Montana, Flathead National Forest, Montana State and private lands lie to the west and Glacier National Park lies to the east. The Middle Fork of the Flathead River originates in the heart of the Bob Marshall Wilderness. The upper section of the rivers offers primitive recreation in a wilderness setting from the headwaters to Schafer Meadows, a narrow channel and log jams make the river generally unsuitable for floating. Acclaimed as one of Montana’s most pristine and remote rivers, the Wild and Scenic South Fork of the Flathead River originates in the south end of the Bob Marshall Wilderness and flows northward to Hungry Horse Reservoir. Boats and supplies are generally packed in on mules or horses over mountain passes to reach the headwaters and then packed again from the take-out just above Meadow Creek Gorge, to Meadow Creek Trailhead.
