Clark Fork River

The Clark Fork is a river in the U.S. states of Montana and Idaho, approximately 310 miles (500 km) long. The largest river by volume in Montana, it drains an extensive region of the Rocky Mountains in western Montana and northern Idaho in the watershed of the Columbia River, flowing northwest through a long mountain valley and emptying into Lake Pend Oreille in northern Idaho. The Pend Oreille River, which drains the lake to the Columbia, is sometimes included as part of the Clark Fork, giving it a total length of 479 mi (771 km), with a drainage area of 25,820 sq mi (66,870 km²). In its upper 20 mi (32 km) in Montana near Butte, it is known as Silver Bow Creek. Interstate 90 follows much of the upper course of the river from Butte to northwest of Missoula.

Alberton Gorge - Clark Fork River

This large volume river runs through a scenic canyon, not far from Missoula, MT. With 5 major rapids - class 2-3, the Alberton Gorge river trip is a popular boating destination and a fun day trip of 16 miles. In early season (May-June), depending on snowmelt and weather, the river is high and the wave rapids get very large. As the water level drops throughout the season, the rapids become less challenging and offer many options for whitewater fun. This trip is appropriate for kids and seniors, depending on the water levels.
