Description: About Lower Clark Fork River

The Lower Clark Fork River is approximately fifty miles west of Missoula and below the Alberton Gorge. This section of the Clark Fork looks and smells a bit different from the river that runs through Missoula. Above the town of St. Regis the river is broad and runs with very little gradient making for some of the best dry fly water in the state. Below St. Regis the gradient increases as the river runs north to meet the Flathead in Plains, Montana offering more diversity with big riffles and boulder strewn runs. The Lower Clark Fork is a terrific fishery and it's location to I-90 make it very accessible. Give a shout anytime if you need more info or you want to book a trip. 800-596-0034.
