Kootenai River Professional Review and Guide
"The Kootenai is perhaps Montana’s best Blue Ribbon secret, and due to its distant location in the extreme northwest corner of the state, it is likely to stay that way. Even by western standards, the Kootenai is a large river. Low flows on the Kootenai regularly exceed the Madison River at peak runoff. The river takes it name from the Kootenai Indians who fished and hunted this region 3,000 years before the first white settlers arrived. The Kootenai flows through the shadows of the Cabinet Mountains to the south and the majestic Purcell Mountain Range to the north.
