At Lake Altoona, one of the major water sources for the city of Atlanta, drought has already left water levels 12 feet below normal. And if it continues, lake levels could fall another foot per week.
"If the lake continues to fall, it will be a concern that we all conserve water, so we'll all have water, to take our showers, use the toilets and have drinking water," said Michael Lapina with the Army Corps of Engineers.
While some enjoy the unseasonable heat, forecasters say normal October temperatures will likely return to much of the U.S. later this week.
