Livestock Water Rights in Texas: What Every Producer Needs to Know

Water is the foundation of every livestock operation in Texas. Whether you run cattle on the Rolling Plains, raise goats in the Hill Country, or manage a mixed operation in South Texas, your ability to water your animals legally and reliably depends on understanding a set of rules that most producers never fully read until a problem forces them to.

Texas divides water into two legally separate categories — surface water and groundwater — and the rules for each are dramatically different. Water law in Texas divides resources into two basic categories: what flows above the surface and what lies beneath it, and this legal distinction means that the rules for using each type are different. Getting this distinction wrong can expose your operation to permit violations, water disputes, or loss of access during drought. This guide walks you through each layer of the system so you can protect your herd and your property.

Important Note: This article provides general educational information about Texas water law and is not a substitute for legal advice. Water rights vary by location, river basin, and aquifer district. Consult a licensed Texas water rights attorney or contact the TCEQ before making permitting decisions.

How Texas’s Water Rights System Affects Livestock Producers

Surface water in Texas is owned by the state and held in trust for the citizens of the state, and the state grants the right to use this water to different people, such as farmers, ranchers, cities, and industries. That creek running through your pasture? The water flowing through it belongs to Texas, not to you — even if you own the land on both sides.

Texas has two distinct legal systems governing water: groundwater and surface water. Surface water is owned by the state, which grants water rights to use specific volumes of water for beneficial uses. For livestock producers, this split system creates both protections and obligations that directly affect daily ranch operations.

The surface water system runs on what is called the Prior Appropriation Doctrine. The Prior Appropriation Doctrine can be summed up by “first in time, first in right.” The first water rights — senior water rights — must be satisfied before the later water rights — junior water rights. If you hold a newer permit and a drought hits, your access may be cut before an older permit holder loses a drop.

Livestock producers get one major carve-out from this system. An exception to the prior appropriation system is the landowner’s qualified riparian rights for domestic and livestock use. This means that if your land borders a stream, you can water your animals without entering the permitting queue at all — within defined limits.

Key Insight: Your location within a specific river basin shapes your actual access to surface water. Your location within a specific river basin — such as the Brazos, Concho, or Rio Grande — can influence your access to surface water in Texas, and the state manages water rights within each basin based on regional supply, seniority of permits, and local conditions.

Groundwater operates under a completely different legal framework. Groundwater — water under the dirt, accessed via wells — is governed by the “Rule of Capture,” meaning the landowner owns the water beneath their property and can pump it, subject to local groundwater conservation district rules. This gives Texas ranchers broad pumping rights, but local districts can layer additional rules on top of that baseline.

Stock Water Exemptions and What They Cover in Texas

The most producer-friendly provision in Texas water law is the domestic and livestock exemption under Texas Water Code §11.142. Under Texas Water Code §11.142, you can use surface water without a state permit for domestic and livestock purposes — if your property borders a stream, you can divert water directly for household use and watering livestock. This riparian right predates the modern permit system.

The exemption is broad but not unlimited. Exempt livestock use does NOT include irrigation of crops, even for livestock grazing, because irrigation is an agricultural use of water and requires a water right. If you want to pump river water to flood a pasture for grazing, that use falls outside the exemption and requires a TCEQ permit. Watering animals directly from a stream or stock tank does not.

The definition of livestock under this exemption follows the Texas Agricultural Code. For purposes of this definition, the terms livestock and exotic livestock are to be used as defined in Section 142.001 of the Agricultural Code. That means cattle, horses, sheep, goats, swine, and exotic livestock species can all qualify — but you should verify your specific animal category if you run a non-traditional operation.

There is also a parallel exemption for stock tank construction. One of the more favorable policies for landowners is the stock tank exemption, which allows private construction of dams, ponds, and small reservoirs without going through the full TCEQ permitting process. You may construct a pond, dam, or reservoir that captures up to 200 acre-feet of water per year, and the water must be used for domestic or livestock use, fish, or wildlife management.

One common mistake is assuming the exemption extends to commercial water sales. If the owner of water in a dam or reservoir exempt under TWC §11.142(a) desires to use that water for a nonexempt purpose — such as commercial use — the owner must first obtain a permit to do so from the TCEQ. Selling water from your stock tank to an oil and gas operator, for example, takes you out of the exemption entirely. For context on the broader livestock transport framework in Texas, see the guide to transporting livestock laws in Texas.

How to Secure a Water Right for Livestock Use in Texas

If your planned water use exceeds what the domestic and livestock exemption covers — for example, large-scale irrigation to support a feedlot or a reservoir larger than 200 acre-feet — you need a formal water right from the TCEQ. If there is no existing right, you can apply for a new permit by contacting the TCEQ. This is an involved process that requires you to demonstrate a beneficial use for the water and prove that enough unappropriated water is available in the source.

The application process involves several concrete steps. You must demonstrate that the use is beneficial, such as for livestock or domestic purposes. You submit an application detailing the location, amount in acre-feet, and intended use, then participate in public hearings and respond to any objections from nearby water right holders or communities.

The Water Rights Permitting Team typically processes simple and uncontested applications within 300 days. In some cases, a public notice may be required, or a request for a contested case hearing may be received, which could increase the processing time. Plan for this timeline well before you need the water — starting the process after a drought has already begun is too late.

You can submit applications to the TCEQ Water Rights Permitting page. Water right applications should be submitted in two parts: an electronic copy submitted directly to WRPT@tceq.texas.gov, and one hard copy submitted to the TCEQ Central Office, Mail Code 160, with the required payment.

Pro Tip: Meet with permitting and technical review staff at the TCEQ before applying. This helps alert you to potential problems or areas of concern where additional information is needed. A pre-application meeting can save months of back-and-forth.

Once issued, a water right is tied to a specific location and purpose. Failure to secure proper authorization may jeopardize your existing water rights or lead to fines and legal action. Each permit is tied to a specific location and purpose, so if you’re making changes — like transitioning from irrigation to wildlife management or expanding for other purposes — an amendment may be necessary. If you also haul livestock and need to understand the equipment requirements for your operation, the guide to livestock trailer requirements in Texas covers those rules in detail.

Stock Ponds, Reservoirs, and Impoundment Rules in Texas

Stock ponds — called “tanks” in Texas ranching culture — are one of the most practical tools for securing reliable livestock water. A well-placed stock tank captures natural surface runoff before it leaves your property. By strategically placing ponds in natural draws, you provide surface water for cattle and local wildlife. When sited correctly, a tank also reduces dependence on wells and streams during dry spells.

The 200 acre-foot threshold is the number every Texas rancher needs to know. You can build a dam, pond, or reservoir on your property storing up to 200 acre-feet of water without a permit, as long as the water is used for domestic, livestock, fish, or wildlife purposes. One acre-foot equals roughly 325,850 gallons — enough water to cover one acre of land one foot deep. A 20-acre pond averaging 10 feet deep holds approximately 200 acre-feet, which is the maximum allowed under Texas surface water rights exemptions.

There is also a parallel wildlife management exemption. Texas Water Code §11.142(b) allows for the impoundment of up to 200 acre-feet of water on a person’s property for fish and wildlife purposes, so long as the property on which the dam or reservoir is to be constructed is qualified “open-space land” as defined by Section 23.51 of the Texas Tax Code. Ranchers who hold an agricultural or wildlife valuation may qualify for this additional pathway.

The exemption applies to diffused surface water — rainfall and runoff that has not yet entered a defined watercourse. Diffused surface water is one example where surface water can be appropriated for private use without a water right permit. Water present on the surface of land that has not yet entered a navigable stream is called diffused surface water — generally rainfall runoff or floodwater that has been trapped in upland areas after flood waters have receded.

If your dam sits on a stream rather than capturing upland runoff, different rules apply. Texas law provides that diffused surface water can be impounded in tanks by the landowner on their own property without a permit, so long as the reservoir does not exceed 200 acre-feet in storage capacity and the water is used only for domestic and livestock purposes. A permit is required if the reservoir exceeds the storage limits, if the dam is on a stream, or if the water is to be used for other purposes.

Scenario	Permit Required?	Key Condition
Stock tank under 200 acre-feet on upland runoff	No	Livestock/domestic use only
Dam placed on a stream	Yes	Requires TCEQ impoundment permit
Reservoir over 200 acre-feet	Yes	Exceeds exemption threshold
Tank used for commercial water sales	Yes	Nonexempt purpose triggers permit requirement
Wildlife/fish pond on open-space land under 200 acre-feet	No	Must meet Tax Code §23.51 open-space definition

Some river basins carry additional oversight. Some basins — including the Brazos, Concho, and Rio Grande — have active Watermaster programs with additional oversight. If your ranch sits within one of these basins, check with the relevant Watermaster office before breaking ground on any impoundment project.

Groundwater Access for Livestock Operations in Texas

For many Texas ranchers, a water well is the backbone of the entire operation. Wells are often the backbone of Texas ranch water systems, but not all wells are equal. Depth, aquifer type, production rate, water quality, and long-term sustainability vary significantly by region and geology. Before drilling, it pays to understand both the legal framework and the physical characteristics of the aquifer beneath your land.

Groundwater in Texas is governed by the rule of capture, derived from English common law’s principle of “absolute ownership.” This means that once water is captured by a well and brought to the surface, it legally belongs to the landowner. Texas law further codified this right: SB 332, passed in the 82nd Legislature, stated that “a landowner owns the groundwater below the surface of the landowner’s land as real property.”

That ownership right is real, but it is not absolute. Chapter 36 of the Texas Water Code designates Groundwater Conservation Districts (GCDs) as the state’s preferred method of managing groundwater resources. These districts function as local government bodies that regulate well drilling, set pumping limits, and develop long-term plans for the aquifers beneath their boundaries.

Livestock operations benefit from an important GCD exemption. Not every well needs a permit. Districts must provide an exemption for wells used solely for domestic purposes or livestock watering, provided the well meets two conditions: it sits on a tract larger than 10 acres, and it is drilled or equipped so that it cannot produce more than 25,000 gallons per day. Both conditions must be met. A small-capacity well on a 5-acre lot wouldn’t qualify, and a high-capacity well on a 100-acre ranch wouldn’t either.

A district cannot restrict production from a well that qualifies for this exemption. However, if you take water from an exempt well and sell it to someone else, the district can assess production and export fees on that water. The exemption protects personal and agricultural use, not commercial resale.

Water quality matters as much as quantity for livestock health. In many transactions, water quality matters as much as quantity. Salinity, mineral content, and treatment needs affect livestock health, infrastructure cost, and long-term viability. Have your well water tested before relying on it as a primary source for your herd. Local GCD districts can impose well-spacing requirements, set limits on how much water can be withdrawn, and require landowners to report their usage. If you’re located in an area governed by a GCD — and many agricultural zones are — review their guidelines before installing a new well or scaling up your water use.

Texas has nine major aquifers that underlie most of the state’s agricultural regions. In Texas, most groundwater is stored in aquifers. The state’s nine major aquifers hold 97% of groundwater: Ogallala, Gulf Coast, Edwards, Carrizo-Wilcox, Trinity, Edwards-Trinity, Seymour, Hueco-Mesilla, Bloson, and Cenozoic Pecos Alluvium. Your region’s aquifer determines how deep you need to drill, how much water is available, and which GCD rules apply.

Water Rights During Drought and Shortage in Texas

Drought is a recurring reality for Texas livestock producers, and the legal rules around water access shift significantly when surface water becomes scarce. The priority date of a water right establishes a place in line of junior and senior water rights. It is the determining factor when water rights are cut back or curtailed in times of shortage, regardless of the type of use of a permitted right.

Junior permit holders face real risk during severe droughts. During drought shortages, surface water rights can be completely curtailed based on the priority date. Many of the most senior rights in Texas rivers are near the coast, rendering most upstream rights vulnerable. This means a rancher in Central Texas with a relatively new permit could lose access to surface water before a downstream user with a century-old right loses anything.

Temporary permits carry the greatest exposure. Temporary permits are issued to use surplus water during wetter times for a period of 3 years or less. In drought or other shortage, these water rights are the first to be curtailed. If your livestock operation relies on a temporary permit as a primary water source, build in a backup plan before the dry season arrives.

Domestic and livestock users who qualify under the §11.142 exemption are protected differently. Regardless of the priority date, whenever there is less water than is needed to satisfy all water rights in a basin, each appropriated right is subordinate to domestic and livestock use. This is a meaningful protection — it means your right to water your animals from an adjacent stream is not subject to the same curtailment risk as a commercial irrigation permit.

Groundwater during drought falls under GCD authority. Limiting groundwater use during drought is the responsibility of groundwater conservation districts. Permit holders can be required to have plans to reduce demand during drought, but enforcement of the required reductions is challenging. Exempt livestock wells — those under 25,000 gallons per day on tracts over 10 acres — remain outside the GCD’s direct permit authority even during drought, though local drought restrictions may still apply.

In some parts of the state, a Watermaster program actively manages water allocation. In some parts of the state, watermasters allocate water between users and ensure compliance with water rights. Some basins — including the Brazos, Concho, and Rio Grande — have active Watermaster programs with additional oversight. Producers in those basins should know their Watermaster’s contact information and understand the reporting requirements before a drought emergency forces the issue.

Pro Tip: Build redundancy into your water system. Installing rainwater harvesting systems — capturing runoff from the metal roof of a barn or barndominium — can yield thousands of gallons of water annually. This water is excellent for reducing the strain on your primary well. Combining a well, a stock tank, and a rainwater system gives your operation multiple layers of protection when any single source fails.

You can check the status of existing water rights in your area using the TCEQ Water Rights and Drought page, which includes information on priority calls and how to file a water rights complaint. For questions about enforcement or to report a violation, the TCEQ’s Water Rights Permitting Team can be reached at 512-239-4600 or at wras@tceq.texas.gov.

Understanding the full picture of Texas livestock water rights — from surface water exemptions to GCD rules to drought priority — is not just a legal exercise. It is a practical necessity for keeping your operation running in a state where water availability can shift dramatically from one season to the next. Review your current water sources, confirm which exemptions apply to your land, and consult a Texas water rights attorney if your operation depends on a permitted right that could be at risk.
