I've put a boat in below the dam with most, maybe all of the floodgates open, but I don't think I'll chance it for a week or two.
I practically grew up down there since we lived on the end of Georgia Mountain that the south end dam is built into and I can tell you that the rollers that I saw today were probably the biggest that I've ever seen down there. There's a stage or 2 with water level and flow that it gets crazy. Today was one of them.
