This includes dock permits, development related issues and more. To top What is a/the "drawdown"? SCE&G conducts a planned “drawdown” each year in early fall. This results in a lowering of Lake Murray’s water level. The drawdown is conducted in preparation of late winter and early spring rainfall. It also serves certain ecological benefits resulting in a healthier lake environment. The drawdown is usually gradual at about a foot per month with the total drop usually being between 4 and 8 feet.
