Each river is different, and hazards include log jams and sweepers, rapids, diversion dams, fences, low bridges, and tight bends.
Water levels can be either too high or too low.
Be sure to check out a float beforehand by reading about it in one of the books on floating Montana rivers widely available in Montana. Also talk to area fly shops, to get up to date information, such as where the latest beaver-cut cottonwood blocks a channel. Disease Whirling disease has infected many Montana streams. In some waters it has caused big decreases in rainbow trout, and in others, so far, the effect has been minimal. I have provided links to sources of information on this serious problem.
