A historic drought has left farmers fighting for their crops and praying for rain.

This century, Texas could face the driest conditions it has seen in the last 1,000 years, according to a new study from a team of Texas A&M University and University of Texas at Austin researchers. The study highlighted a slew of looming problems for the state’s water supply. This problem will be particularly pronounced for Dallas, which relies entirely on surface water for its water supply, the study says. “And if there is a shortage, then the very next step is they have to determine how they are going to meet their water supply needs for that growing population,” she said. So the state is well-prepared and is looking at future populations and water supply needs for municipalities.”But the warnings are alarming to water conservation advocates and ranchers alike.
