From what I understand it is. I hear you can even float a raft at this level. I've never run it any where near this low so I'm kinda excited to see what it will look like. Last time I ran it was last year at 3600.
You can boat it in a kayak as low as the native flows will go...you can still float most of it in a raft as well, but there are at least 2 problem spots where 80%+ rafts will have to be pushed/pulled across. Not much fun, but still do-able.
