ROBERT LEE, Texas | 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.

Of course, dirty cars are the least of their concern. It’s become a question of
survival. Texans in this semi-arid region are accustomed to making due with
little water, but the sense of urgency has never been so high, said Melinda
McCutchen, who edits the local newspaper. Since October, Robert Lee residents
have cut water consumption by 80 percent.
