Blackfoot River, Montana

Blackfoot River is situated in western Montana and has become one of the state’s most famous rivers for recreation.

Blackfoot’s headwaters are between Rogers Pass to the north and Stemple Pass to the south. The river then flows westwards across Milltown before draining into the Clark Fork River.


Over the years, Blackfoot River has undergone several changes due to mining and flooding. The river meanders through spectacular canyons and valleys formed by the Missoula Floods at the end of the ice age.

In 1975, a dam failure released toxic mine pollutants into the river, killing a large trout population downstream.

Human activities such as mining, logging, irrigation, and grazing caused further damage to the river before restoration efforts in the 2000s.

The first people to settle near the Blackfoot River area were Native Americans. The Salish, Nez Perce, and Pend d’Oreille tribes have occupied this place for about 10,000 years.

Natives used the area for bull trout fishing, summer hunting, and as a trail between the Great Plains and Continental Divide.

The novella, A River Runs Through It (1976) and its 1992 film elevated the river from a trout fishing stream to a popular attraction for fly fishing, rafting, hunting, and camping.
