The lake is now at 1,058 feet above sea level, or 13 feet below full pool, officials said.
The last time Lake Lanier hit such a low mark was during the 2007-09 drought, when the lake was at 1,050.79 feet, The Times of Gainesville reported.
The U.S. Army Corps of Engineers predicts that Lanier could drop to 1,055.2 feet by Dec. 21.
“There has been very little rain anywhere in the basin over the last two weeks and it appears that this will continue over the next few weeks as well,” the agency stated in its recent drought update for the Apalachicola-Chattahoochee-Flint River basin.
The basin includes portions of Georgia, Florida and Alabama.
“We are approaching the time of year where we will typically begin seeing frontal systems move through the Southeast, bringing much-needed rain to the basin,” the agency’s drought report states.
“While the two-week outlook shows no significant rain, the extended climatic outlook still indicates equal chances of above or below average rainfall for the upcoming winter months.”
