I was in there a couple weeks ago with AdamG. We put in at the bridge over the Grey Wolf and paddled out to the fish hatchery. Flow was a little over 1000cfs. Good fun at that level.
There is lots of wood in both sections; I think at least 4 or 5 that required getting out of the boat and portaging. There were a few that were able to be skirted or ducked. Nothing that came up quick; all could be seen from a distance and there were eddies for portaging at those levels.
