Should we be worried about the water?

It hasn't rained much around here this spring, and summer's looking like it's going to be really dry. Our neighbors in places in Allen, Frisco and Little Elm are sounding alarms like they're going to dry up. And by the looks of Lavon Lake, they may be right. Many of our neighbors are already down to one-day-a-week watering. Meantime, the taps are full here in Flower Mound, or so I suppose. We're still on our regular rationing, which is "don't water between 10a and 6p, but go at it any other time". Is that going to change soon, if the rains don't come? Any insider knowledge?
