Missoula / Bonner

Blackfoot River

The river of A River Runs Through It, flowing west from the Continental Divide near Lincoln to its confluence with the Clark Fork at Bonner. Mostly Class I-II float water with a few Class III rapids that firm up during spring runoff, then a relaxed float and tubing river as flows drop through summer. The lower ~27 miles, Russell Gates to Johnsrud, run through the cooperative Blackfoot River Recreation Corridor managed by FWP, BLM, and private landowners.
