Take this info with a grain of salt because it's been probably 3 or 4 years since I last ran it, but I would not recommend running it in a raft due to blind corners scrambling for micro-eddy situations above bad strainers.
If you get a reliable, recent report that it's clean, then you might have a good time. There's no big drops or bad holes, just fast and very few eddies. I've done it when Plateau @ Cameo gauge read 600 and 1,100. 600 I wouldn't go back, not enough water. At 1,100 it was pretty fun, but really fast so the blind corners and wood were a concern.
Damn it feels good
