ETCUMMING, Ga. - With water supplies rapidly shrinking during a drought of historic proportions, Gov. Sonny Perdue declared a state of emergency Saturday for the northern third of Georgia and asked President Bush to declare it a major disaster area.Georgia officials warn that Lake Lanier, a 38,000-acre reservoir that sup­plies more than 3 million residents with water, is less than three months from depletion. Smaller reservoirs are dropping even lower."
