I happened on this discussion of the Rogue. I did not catch this round of high water but have in the past. You wait until the water drops a bit and the risk of trees in the river is greatly reduced. The Illinois comes in below Agness, but when it is raging, the flow from the Illi partially backs up the Rogue (well, only a bit!) but there are waterfalls side-creeks everywhere, especially from Marial down so lots of added water on the "coast side of the mountains". I counted over twenty waterfalls from Tate Creek to Wild river Lodge. Most rapids are washed out, or the river is wide enough to miss the nasty spots except Blossom: it is fast with Gr. Canyon waves, and Plowshare has a bad double-wave that flipped a small raft on one of our trips...Horseshoe Bend has crazy hydrlics. Mule Creek canyon was almost peaceful, way up the wall and wide. But that was on trips 50 to 70, 000. Will's trip was definitely bigger. Maybe someday...
The trip at these flows takes about 4 to 5 hours. You can make it to the coast in 10.
