The southeastern United States suffered from a severe drought in 2007. The cause of the drought was generally ascribed to climate change resulting from global warming. The city of Atlanta, Georgia, dependent for its water supply on Lake Lanier, was slow to recognize the seriousness of the crisis. It was only in the fall of 2007 that restrictions on the use of water were imposed.
The southeast is not normally subject to severe drought, and, despite rapid population growth in the 1990's and 2000's, state and local governments have generally not engaged in rigorous planning regarding water management.
