A couple weeks ago, I took some friends down the Upper Tumwater section of the Wenatchee River. It had been a while since I’d paddled this stretch, but it is a very wide section of the river and the rapids are seemingly less difficult than the main section of Tumwater Canyon. It is still considered class III-IV, especially when paddled at higher volumes.
The first rapid of the run starts after about 3/4 of a mile of flat water. It consists of a large entry wave followed by several exploding laterals and tapers off into some boogie that braids through a shallow boulder garden. The day we paddled it, we dropped in just assuming everything was all good. Bad call on my part.
