As north Georgia continues to experience its worst drought in more than a century, many colleges in the region are struggling with water woes, with some seeking lessons from colleges that have survived droughts before. Climatologists say that the drought may intensify this spring and summer, and that emergency measures are overdue. Now that the situation has become a crisis, colleges and universities in the region, along with other water users, face state and local mandates to cut their water use by 10 percent to 15 percent. On many campuses today, fountains are turned off, campus vehicles go unwashed, and normally verdant lawns have turned brown.
