I was with Mike this weekend. I thought I'd put this up there if anyone is heading out in the next couple days....
Most of the wood issues are fairly obvious when you come up on them - I attached pics of the one that is not, and it happens to be in the pushiest section. There is a log underwater just below the bottom of the only slot that 'looks' like the path of least resistance. Be careful, we were scouting when these guys went through. The creeker get through, the yellow jackson dove too deep and got hung up on the log below the surface.
Hard to say just how dangerous it is, but we walked it after watching that.
Also, watch out for the river-wide log after the bridge. I almost floated into it.
