Water law is one of the most contentious and frequent legal issues Texas landowners face. As the adage goes, “Whiskey is for drinkin’ and water is for fightin’.” Texas property owners need to understand the basics of Texas water law as well as their rights and legal limitations related to the use of water on their property. Texas water law divides water into two broad categories: groundwater and surface water. Different legal frameworks and regulatory structures apply to each category, making Texas water law more complex than other states that follow a single legal approach for all waters.
