I went there on Sunday.
The track to the washout track (along the fenceline) had some BIG rocks placed strategically to prevent people going beyond a certain point.
Not sure if one had been moved, or they weren't set up properly, but you could still drive to the washout (we didn't)
The river was up real high and the usual mud holes weren't accessible from the South road at all, so I don't know about that area.
Not many places left.
