Lake Lanier's elevation has dropped to a level it hasn't been at since before a historic two-year drought that ravaged Georgia ended on Oct. 14, 2009.

The North Georgia reservoir stood at 1,066.87 feet above sea level on Sunday and has been lower than 1,067 feet since Tuesday, according to U.S. Army Corps of Engineers data.

Summer full pool is 1,071 feet above sea level.
The last time the lake stood at a lower elevation was Sept. 20, 2009, when the elevation was 1,065.55 feet.

The next day, the lake jumped to 1,067.31 feet and stayed on a steadily increasing course until topping 1,071 feet on Oct. 14, 2009, ending a drought that saw Lanier drained to a historic low 1,050.79 feet on Dec. 26, 2007.

Lack of rainfall is driving the lower elevations.
