River Description

The Big Hole is a great beginners run, its actually one of the rivers that i started to learn on. The run is mostly small rapids, with the occational pourover/cartwheel spot. The run is very straight forward, and can be scouted from inside your boat. During the summer beware of fishermen and drift boats (theres alot of them, especially when the salmon fly hatch is kickin). Of course alway be weary of logs, and there is a MANDITORY portage at the diversion dam. I heard that a couple of years ago a couple of drift boats went over this and where kept there for a couple of days. Other than the dam there are no known hazards.

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!
