It then flows into Montana receiving the East and the West Fork Yaak Rivers. You won’t ever have to worry about crowded fishing conditions on this remote river. Fishing the upper section above the Yaak Falls provides some great fly fishing opportunities with easy wading access. The lower section below the Yaak Falls has fast water with great rainbow trout, but access is a little tricky due to a rock canyon.
The fishing season is open the third Saturday in May through November 30th. Most common species are rainbow, cutthroat, and brook trout.
