We ran this stretch on 6-8 and had a great time. There was a decent amount of wood and several of the islands had channel wide wood that could be very bad. We scouted river right at one island with a massive amount of wood pinned on the upstream side. This had bad wood on the left channel and one large log just under the surface on the left side of the right channel. There are clean lines but be aware. At these flows I felt the whitewater was III+ but many CL III paddlers would find the very long long rapids to be quite a handful. Additionally many CL III paddlers will not have the river awareness to deal with and anticipate wood problems. A skilled crew could route an ambitious CL III paddler with a cool head down, but a beginner crew stepping it up might have a rough time here.

Wild rivers and their enthusiasts got some good news with the release of the new 15-20 year Forest plan for the Flathead National Forest. The decision newly protects 22 streams as eligible for Wild and Scenic designation, based in large part on the advocacy of American Whitewater and our awesome partners and members in Montana. These protections will serve as a vital steppingstone to the designation of some of our Nation’s most outstanding headwater streams.

On May 28 the U.S. Supreme Court denied an appeal by Mountain States Legal Foundation who filed a lawsuit in June 2001 alleging the 1985 Montana Stream Access Law violated their rights under the U.S. Constitution to regulate who floated over their land.

The decision thereby protects Montana's Stream access law and public rights of navigation throughout the State.

The Missoulian newspaper reported on January 5th, 2001 that U.S. District Judge Charles C. Lovell dismissed a case brought by the Mountain States Legal Foundation challenging public recreational rights on Montana’s rivers and streams. This is a huge win for boaters and fishermen!
