River Description

A cool trip through a unconfined canyon that opens onto a broad valley with cottonwood galleries bordering the creek.  Expect almost continuous class III+ water, but you should be a class IV paddler if you get on this run because of some old mining infrastructure in the river (pipes, cables, etc) and the occassional tree that makes the run a bit more consequential.  Go when the water is up.  Be ready for flows to double at the Boulder Creek confluence.

Appeal Challenging Montana Navigability Is Denied

Jason Robertson

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.

River Recreationists Win Big in Montana!

Jason Robertson

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!
