I live real close to the lake and went across the dam yesterday. The dam area is iced over but the ice appears to stop before it gets to the marina. Your right, they aren't putting out as much hot water. I've heard that one of the units is down for repair. I've been there twice this year and did catch some fish but not as many as I usually do.
If I go that way today I'll go by the marina and see for sure and let everyone know.
