Somebody told me that watering the lawn may cause the grass roots to stay too close to the surface and the grass may not be able to withstand dry conditions as well. Is this so?

The question is not simply watering your lawn but how often and how much water you provide. The NDSU Extension Service Yard and Garden Report at http://www.ag.ndsu.edu/yardandgardenreport/documents/2014-08-04/summer-lawn-care explains:
"Lawns need 1 to 1 1/2 inches of water per week, either from you or Mother Nature. Water deeply. It’s better to give your lawn a big drink of water rather than a series of sips.
"Roots grow where the water is. If you water deeply, you will develop a deep root system. If you only sprinkle the surface of the soil, you will create a shallow root system."
