I’ve heard in the past that an inch of rain equates to about a foot increase in lake levels. According to recent articles in The Atlanta Journal-Constitution (AJC) and from the National Weather Service’s Southeast River Forecast Center, that is not the case. The AJC stated Sunday that Lake Lanier adds water only when rain is plentiful and steady. For example (currently), one inch of rain water would have no impact on the water level of Lake Lanier. The lake level would continue to fall, but at a lower rate for a couple of days. So much depends on how saturated the soil is and how consistent the rain has fallen. The real change happens when we get at least 4 inches of rain. According to the 11/25/07 AJC article, the lake would rise 1.4 feet over 5 days, then hold steady.

 

To get up to date precipitation information, and how it’s affecting our lakes, go to the National Weather Service’s Southeast River Forecast Center website. Not only does it have current and forecasted moisture statistics, but also you can listen to a Power Point presentation on the Southeast Water Resources Outlook.
