It is too low for most people's taste. I've run it a few times this year and I liked it but I will run anything low. My guess is that the flow is going to step up every day from here to peak flow so if you have never run it before and class IV makes you nervous then now is a good time to get on it to get a feel for it before it starts flowing.
I pulled a large strainer out of the screaming quarter mile and there was another dangerous one downstream of it that someone else must have pulled out because it is gone now.
I ran Black Rock this weekend and we pulled 3 pieces of wood out of Black Rock proper and saw what I would say is an above normal number of logs in the river over all. They are mostly old logs so I don't know how to explain why there are so many this year. Be heads up this year because it looks like a lot of them will start moving with more water.
The undercut at Black Rock contains a giant log that isn't going anywhere. I don't know if it is worth pulling out, but if someone needs some exercise then go for it. It might be a good idea to saw it up so a tourist doesn't throw it back in.
I cleaned out the strainer below Rigor Mortis.... It had a piece of lumber spanning the width that I noticed at the end of last season. So, feel free to swim the left side below Rigo
