Water Rights in Texas: What Every Landowner in Central Texas Needs to Know

If you're buying or selling land in Coleman, Brown, Callahan, Concho, McCulloch, Runnels, or Taylor County, water is one of the most important conversations you'll have. It might even be the most important one. Out here in Central Texas, we don't take water for granted. We've seen enough dry summers and cracked creek beds to know that understanding your water rights isn't just legal homework — it's survival for your operation.

Texas water law is genuinely complicated, and a lot of buyers come to the table not knowing what they don't know. That's not a criticism. It's just reality. Water law in this state has been shaped by decades of court decisions, legislative changes, and two entirely different legal doctrines that sometimes seem like they're playing by completely different rules. Let me walk you through the basics in plain language, because knowing this stuff matters when you're putting your money into Central Texas land.

Texas operates under two separate water rights systems depending on whether you're talking about surface water or groundwater, and the difference between those two is not just technical — it changes everything about what you can do with water on your property.

Surface water in Texas — meaning rivers, creeks, lakes, and streams — belongs to the state. That's not a mistake. The state of Texas owns surface water, and you have to have a permit from the Texas Commission on Environmental Quality, the TCEQ, to use it. This goes back to the doctrine of prior appropriation, which is sometimes called "first in time, first in right." The folks who got their surface water permits a long time ago have senior rights, and in drought years, junior permit holders can be cut off before senior holders are. Out here we have the Colorado River running through parts of this country, and the LCRA — the Lower Colorado River Authority — plays a significant role in how that water gets managed and allocated. If you're thinking about irrigating from a river or creek, you need to understand where you stand in that permit hierarchy before you make any assumptions about what water you'll actually be able to use.

Now here's where it gets interesting. Groundwater in Texas operates under a completely different doctrine called the rule of capture, sometimes called the law of the biggest pump. Under this rule, a landowner generally has the right to pump groundwater from beneath their property and use it however they see fit, even if that pumping affects their neighbor's well. There are some limits and nuances to this now, but the basic premise holds. Your groundwater is considered your private property right. This is fundamentally different from surface water law, and it's one reason folks in the oil and gas business have historically felt comfortable doing business in Texas — private property rights run deep here, literally.

But groundwater in Texas isn't entirely unregulated anymore. That's where Groundwater Conservation Districts come in. Most of our Central Texas counties fall under one or more of these districts, and they have real authority to regulate how much you can pump, require permits for new wells, and set spacing rules between wells. The Lone Star Groundwater Conservation District, the Central Texas Groundwater Conservation District, and others cover different parts of our area. Before you drill a new well or plan a significant agricultural irrigation operation, you need to know which district you're in and what their current rules are. These districts have become more active as pressure on aquifers has increased across the state.

Speaking of aquifers, out here in Central Texas we're largely dependent on the Colorado River system for surface water and on local aquifers for our groundwater. Parts of Concho, McCulloch, and Coleman counties sit over portions of aquifer systems that supply domestic and livestock water to thousands of rural properties. The depth to water varies considerably across this region. In some areas you can hit decent water at a couple hundred feet. In others you're drilling much deeper and spending considerably more money. If you're looking at a piece of land and the only water well is shallow, that's a conversation worth having with a local well driller before you close.

One thing I see buyers overlook is the distinction between a water well that exists on a property and the actual water rights that go with it. When you buy land in Texas, you generally acquire the groundwater rights beneath that property as part of the purchase, unless those rights have been severed and sold separately. Yes, groundwater rights can be severed from the surface estate, just like mineral rights can. And just like with minerals, a previous owner could have sold off the groundwater rights and they may not convey with the land. In this part of Texas where minerals have been actively leased and traded for generations, it's worth doing the same due diligence on water rights that you'd do on minerals. Ask specifically whether groundwater rights are included and get that confirmed in writing.

Stock tanks and ponds are a big part of ranching life out here, and they bring their own set of considerations. Water that falls from the sky onto your land and runs into a stock tank you built is generally considered exempt from the surface water permitting requirement for livestock and domestic use. But if you're talking about capturing significant runoff from a creek or diverting surface flows, you're moving into state-regulated territory. Most small ranch stock tanks used for cattle water fall comfortably within the domestic and livestock exemption, but if you're planning something larger scale, it's worth a call to TCEQ to understand where the line is.

Riparian rights is another term buyers sometimes hear, and it causes some confusion. Texas does recognize a version of riparian rights for landowners whose property borders a stream, but in practice surface water is primarily managed through the state permit system. Having land that borders the Colorado River or a creek doesn't automatically mean you can pull water from it freely for irrigation purposes without a permit. It does matter for access and certain other purposes, but don't assume that waterfront frontage equals unlimited water use.

For anyone buying land with an existing irrigation system or an active agricultural water right, I'd strongly encourage getting a copy of any permits associated with that property before closing. Water permits don't always show up cleanly in a title search the way property deeds do, and a good agricultural real estate attorney who understands Texas water law is worth their fee when significant water infrastructure is involved in a purchase.

Drought is a reality we live with out here. The years we've had where stock tanks dried up completely and folks were hauling water to their cattle are not distant memories. When you're evaluating a piece of land, ask about how the water sources performed during the worst drought years in recent memory. A seller who's been on that property a long time can tell you how the wells held up in 2011 and 2022, and that information is more valuable than almost anything else you can learn about the water situation.

One last practical point — if you're planning to develop land or put multiple water wells on a piece of property, get familiar with the setback and spacing requirements in your groundwater conservation district. These rules exist for legitimate reasons and violating them can create real problems down the road.

Water is the foundation of land value and land use in Central Texas. The rancher who has reliable water year-round has something fundamentally different from the one who's always worried about it, even if their fence lines look the same from the road.
