All the cars in this town are dirty. Gripped by drought, the lake that has provided the town's only source of water has just about dried up -- as of last month, it was less than 1 percent full. And as a result, residents are prohibited from using water to wash cars, water trees and lawns and irrigate plants.
Drought is not unusual in Texas, said climate scientist Katharine Hayhoe of Texas Tech University. For example, the last drought of record in Texas occurred in the 1950s. But the severity of last year's high temperatures compounded with the lack of rainfall and a growing population have put an unprecedented strain on water resources.
