I was there this past weekend, and it's easily a class 3+, if not a class 4. There are a variety of runs, some of which are more scout able than others. The bigger water tends to be at the top, with a few smaller class II+ channels on the left. Anything on the left is scoutable, and there are bridges between some of the islands. The right side might be scoutable, but it would be a lot more work and I don't know for sure if there is anything. The small channels are a tight technical run, with a couple potentially dangerous strainers near the bottom. It eventually empties out into a main Chute with a long run-off.
