Do I own the water under my land in Texas?

Water can feel like the most confusing part of buying land, and Texas law does not make it simpler with one universal rule. The clean way to think about it is to separate the water under the ground from the water running across the surface. Texas treats those two very differently, and each matters in a different way.

Groundwater is a private property right

Texas courts have long treated the groundwater beneath land as a real property right that belongs to the landowner, and the Texas Supreme Court reaffirmed that view in 2012 in Edwards Aquifer Authority v. Day. In practical terms, the water under your land is yours to access, and Texas has managed that access under the rule of capture, a doctrine that traces back to an 1904 case. Under the rule of capture, a landowner can pump water from beneath their own land and generally is not liable for how that pumping affects a neighbor's well, so long as the pumping is not wasteful, malicious, or negligent. That is a powerful right, and it surprises many new buyers who assume water belongs to the public the way it does in some other states. The basics of Texas groundwater law from Texas Living Waters offer a good plain-language overview.

Groundwater districts can change the rules

Texas manages groundwater locally through groundwater conservation districts created under Chapter 36 of the Texas Water Code. A district can require permits for certain wells, set spacing rules, and track water levels, which means water rules genuinely vary by location. Fannin County, for example, falls inside the Red River Groundwater Conservation District, which also covers Grayson County, while most of the other Northeast Texas counties are not currently inside a district and operate under the rule of capture. District boundaries and rules change over time, so the reliable habit is to confirm the rules for the specific county before you buy. Wells serving ordinary domestic and livestock use are generally exempt from district permitting, and the Texas Commission on Environmental Quality oversees licensed well drillers and the well reports they file.

Surface water is a different story

The water in a river, creek, or other natural watercourse is different: in Texas it is owned by the state, and putting it to use usually requires a state permit. A seasonal creek crossing your property does not automatically give you the right to pump it for irrigation, and a pond fed by captured runoff follows yet another set of rules. That distinction is why a wet weather creek can be a lovely feature but not a dependable water plan, and why a property with a good, proven well often holds its value better than one that only has a creek running through it.

What this means for buyers

For a buyer, the practical takeaway is to ask about the actual water on the property rather than the generic version. Is there a well, how deep is it, and is a driller's report on file? Has the water been tested? Is the county inside a groundwater district, and does that affect the well you plan to drill? These are concrete, checkable questions, and they matter far more than whether a pond or creek shows up in the listing photos. We regularly help clients work through this list before closing.
