I stopped by The Ledges twice on Memorial Day weekend. Weather was fantastic (despite the forecast), and the water was cold but quite swim-able. The lake level was high but not excessively so. Some of the flotsam and jetsam has been floated by the higher water and I'd certainly recommend caution if piloting a motorboat, but otherwise it was a fairly minor problem.
I think the weather forecast may have frightened away quite a lot of people, because there were fewer people there than I would have expected - but you can never frighten away The Ledges regulars. Looking forward to the next weekend that's decent weather-wise, and when I have enough time to stay a while.
