SC, do you have a lake association? I have a friend up here who lived on a much smaller lake than yours and they had so much problems with weed-n-feed run-off that the lake got shut down entirely for quite some time. No one could swim in it and it was really nasty to look at. I thought that was sad, and so very disrespectful of the folks who would not abide by the common-sense lake rules. I guess a manicured lawn was more important than the health of the lake to some...
