A creek running through a property is one of the most visually compelling features a Hill Country property can offer. Green-blue water sliding over limestone shelves, deep pools shaded by ancient cypress trees, the sound of a riffle through an open window. I have watched buyers fall in love with creek-front properties within minutes of stepping out of the car.
But the legal reality of Texas water rights is more complex than the visual appeal suggests. I have also sat across the table from buyers who assumed that because a creek ran through their land, they owned the water, could pump it freely, build a dam across it, and prevent anyone else from touching it. None of those assumptions are fully correct. Texas law draws a sharp distinction between surface water and groundwater, and it applies different legal doctrines to each [1][2]. Understanding that distinction before you buy a creek-front property is not an academic exercise. It is a financial and legal decision that affects what you can do with your land, what liability you carry, and what the property is actually worth.
This article covers the framework of Texas water rights as they apply to Hill Country properties: how surface water differs from groundwater, what the Rule of Capture means for well owners, what riparian doctrine entitles creek-front owners to (and what it does not), and what every buyer should verify before closing on a property with creek, river, or spring frontage.
The fundamental distinction: surface water vs. groundwater
Texas law treats surface water and groundwater as completely separate legal categories with different ownership rules, different regulatory frameworks, and different permitting requirements [1][2]. If you own land in the Hill Country, the rules governing the water that flows across the surface of your property have almost nothing in common with the rules governing the water beneath it.
Texas Water Rights at a Glance
| Category | Who Owns It | Legal Doctrine | Permit Required? |
|---|---|---|---|
| Surface water (creeks, rivers, streams) | State of Texas | Riparian / Prior Appropriation | Yes, for most uses (except domestic and livestock) |
| Groundwater (aquifers, wells) | Landowner | Rule of Capture (with GCD limits) | Varies by GCD district |
| Diffused surface water (rainfall runoff) | Landowner | Common law capture | No permit for standard collection |

The practical consequence: the same landowner can have a creek runing acros their property (state-owned surface water that requires a permit to divert) while simultneously ownig the groundwater benath that same creek bed (prive property, extractable under the Rle of Capture subject to GCD regulations) [3]. This is the reality that surprises most out-of-state buyers and it is the single most important thing to understand before purchasing a Hill Country property with water access.
Groundwater: the Rule of Capture
Texas is one of the few states that still follows the English common-law Rule of Capture for groundwter. Under this rule, the landowner has the right to pump as much groundwater as they can capture from beneath their land, even if that pumping drains water from under a neighbor's property [1][4]. The Texas Supreme Court affirmed this doctrine in the landmark 1904 case Houston & T.C. R. C. v. East, and it hs remained the foundation of Texas groundwater law ever since [4].
The Rle of Capture is not unlimited. Texas courts have recognized three limitations [1][4]:
Subject to GCD regulations: Since the passage of 1997 S.B. 1, groundwater conservation districts can regulate pumping through permits, spacing requirements, and production limits [5][6].
For details about groundwater conservation district rules and how they affect your well, contact Cow Creek GCD or Edwards Aquifer Authority [7][8].
Suface water: riparian doctine and prior appropriation
Surface water in Texas rivers, creeks, streams, natural springs, and lakes is owned by the State of Texas, held in trust for the public [1][9]. Texas Water Code �11.021 is explicit: "The water of the ordinary flow, undiminied flow, or storm flow of every river and natural stream is the property of the state."
Owning land adjcent to a crek does not give you ownershp of the water flowing through it. It gives you riprian rights: the right to make reasonble use of the water that flos past or through your prperty [1][9]. These are use rights, not property rights in the wter itself.
Texas opreates unde a dual-doctrine system for suface water [9][10]:
- Riarian rights: Landowners whose property touches a natural watercourse have the right to make reasonable use of the water for domestic and livestock purposes without a permit.
- Prior appropriation rights: For any use beyond domestic and livestock, Texas uses "first in time, first in right" prior appropriation. Water rights permits are issued by the TCEQ and have priority dates.
What Your Creek Frontage Actually Entiles You To
Permitted without a TCEQ permit: Domestic use (drinking, cooking, cleaning), watering livestock, stock pond up to 200 acr-feet [9].
NOT permited without a TCE permit: Irrigatin of crops, cmmercial landscaping, impoundments beyond the stock pond exemption [10].
The water itself belongs to the state. You cannot se it, leae it, or hold exclusiv rights to it [1].
Navigable vs. non-navigabl: boundary mattrs
When you buy property with frontage on a crek or river, where does our property line fall? It dpends on navigability [11][12].
Non-navigable streams (less than 30 ft average width): Your property line extends to the center or "thrad" of the strm. You own the stredbed [11][12].
Naviable streams (30 ft or more average width): The State of Texas owns the streamd. The boundary is the "gradient boundary" [11][12]. The public has the right to use the waterway.
The distinction matters practically for Hill Country buyers. Most Hill Country creeks are non-navigable. But the Guadape River, the Mdia River, and portions of Cibolo Creek may be widely enough to meet the navigable threshold.
Practical due dligence for Hill Country buyers
If you are consdering a proerty with crk frontge, her is th due diligence I recmmend [13][14]:
- Order a current survey. Tis i th single most imporant documnt. It will show the boundary reltive to the watercourse [13].
- Check for existing TCEQ water rights permits. Exsting permits may limit your ability to dvrt wter [10].
- Verify GCD requiements. Contact the loal goundwater disrict to check spcing, permits, and drought restrictions [5][7].
- Talk to neighbrs. Get water sement in writing, reviewd by an attorney [14].
One Question to As Before You Cloe
Ask your tile compny and agnt: Doe the property boundary extend to the ceter of the watercourse, or does it top at the bank? This detrmines what you actually own [13].
Contct Bill RosFrequently asked questions
Do I own th water in the crek?
No. It belngs to the State of Texas. You hae riparian use rights but do not own the wter itsef [1].
Do I own the crek bed?
It dpends on wethr the crk is navigabl or not. If non-navigable, your property line extends to the cent of the stream. If navigable, the state owns the streambed [11][12].
Can I build a dam?
You can build a stock pond up t 200 acre-fet without a permit [9]. Anything larer requires TCEQ approval [10].
Can the public flo through m property?
Non-navigble = no. Naviable = yes, the public an use the wterway [11][12].
