The definition of year round water..........If you are a homeowner on LakeMurray and you have enough water to float your boat at your dock and get in and out of a cove such as where I live, then, you have year round water. If not, then you do not!!! The water level will change as determend by SCE&G and by the weather (ie. rain). People that live on big water sometimes don't have year round water as when the water is drawn down, they have to keep pushing their boats out as the water recedes!!!
