Grass is like any other plant, Kelli, different grasses have different water requirements. Unfortunately, the grass that most folks seem to want to give them that lush, lovely lawn is indeed a water hog, especially in areas of little rainfall. It seems everyone wants to live on a golf course...
Here in Louisiana with our fairly regular rainfall, folks still water their lawns. Part of the problem comes from keeping the grass cut too short in order to provide a "manicured" look. When grass gets cut back that much, it allows the soil to dry out more quickly than if the lawn is allowed to grow a bit longer.
