What's to know? There are a few different stretches. For the most active stretch, put in below the Applegate reservoir and float through a fun class II/III gorge. DANGER: there is a low-head dam not too far downstream. It is extremely dangerous, definitely the frowny face type. You can see it from the road (as you drive over a bridge) so be on the look out. Fortunately, there is an easy portage on the right. Take out at various locations.
