The summer heat, and drought, is back.

Water levels in much of the Carrizo-Wilcox Aquifer are way down again this year. The levels are known to fluctuate quite a bit throughout the year, but the summer lows keep getting lower every year.

"It's still going up and down," said Gary Hanson, director of the Red River Watershed Management Institute. "It's just in the past few years it's been going down at a rate that's not real good."

Hanson says the biggest problem is people using groundwater to water their lawns too often. Officials say grass can survive a drought more easily if it's only watered once a week and not trimmed too short.
