Texas's Water Level Notice Law for Land Buyers

Texas does not have one general “water rights notice” law. It has a specific, narrow disclosure under Property Code Section 5.019 that applies only when land adjoins a large reservoir, plus a separate patchwork of rules on groundwater and surface water that a buyer largely has to research on their own rather than expect on a form.

What does Texas Property Code Section 5.019 actually require sellers to disclose?

Section 5.019 requires a seller to give written notice, before the sale contract becomes binding, that water levels in an adjoining reservoir rise and fall for reasons outside anyone’s control. According to Texas Property Code Section 5.019, the notice must be delivered “on or before the effective date of an executory contract binding the purchaser to purchase the property,” and it must say, in substance, that the water level of the adjoining impoundment “fluctuates for various reasons, including as a result of: (1) an entity lawfully exercising its right to use the water stored in the impoundment; or (2) drought or flood conditions.”

The statute took effect September 1, 2015, and it hasn’t been substantively rewritten since. It doesn’t ask a seller to describe who holds water rights, how much water is available, or what a groundwater conservation district permits — it only requires a warning that the shoreline the buyer sees on closing day is not the shoreline they’ll always have.

Which Texas properties actually trigger the water level notice?

The notice only applies to land adjoining a reservoir built and maintained under Water Code Chapter 11 with storage capacity of at least 5,000 acre-feet at normal operating level — a size threshold that rules out most of the water features rural buyers actually encounter. Farm ponds, stock tanks, small private lakes, and the amenity lakes built into many rural subdivisions don’t come close to that capacity, so a seller isn’t obligated to give this particular notice for those parcels even if the water level does move around. The properties that do trigger it sit on the shoreline of major reservoirs — the ones behind lakes like Possum Kingdom, Sam Rayburn, and Texoma, where a state-permitted entity controls releases and levels can swing several feet across a normal year.

That distinction matters for a buyer evaluating raw acreage: a tract touching a small ranch pond and a tract touching a major reservoir look similar in a listing photo but sit under completely different disclosure rules. If a listing doesn’t mention the notice, the first question is whether the adjoining water body is actually a Chapter 11 reservoir of that size — not whether the seller forgot to mention something they were required to.

What happens if the seller doesn’t give the notice?

A buyer who signs a contract without receiving the required notice gets a real, time-limited remedy rather than just a complaint. Under Section 5.019, if the contract was signed before the seller delivered notice, the purchaser can terminate the contract “for any reason” within seven days of learning about the water level fluctuations — whether that information comes from the seller, a neighbor, or the buyer’s own research. That seven-day clock is short, so a buyer who suspects the property should have come with this notice and didn’t get one should act on it immediately rather than waiting to see how the rest of the deal shakes out.

If the sale has already closed, the remedy shifts from termination to a misrepresentation claim, and it comes with a higher bar: the buyer has to show the seller had actual knowledge that the water level fluctuates and failed to disclose it before conveyance. That’s a materially harder case to bring than a pre-closing termination, which is one more reason the seven-day window matters more than it might first appear.

Does Texas require any disclosure of groundwater or well rights?

Outside the narrow reservoir notice, Texas doesn’t require a standalone disclosure of groundwater rights, well capacity, or aquifer status for a typical land sale. Groundwater in Texas belongs to the landowner under the rule of capture, a doctrine Texas courts adopted in 1904 and the Texas Real Estate Research Center at Texas A&M University traces through today’s law: a landowner can pump water from beneath their own land for beneficial use, even if that pumping affects a neighbor’s well, subject to narrow court-made limits against malicious or wasteful pumping and to whatever a local groundwater conservation district (GCD) has adopted by rule.

That GCD layer is where most of the real restriction sits, and it isn’t uniform. According to the Texas Water Development Board, groundwater conservation districts are authorized to regulate production through permitting of non-exempt wells, spacing requirements, and other rules aimed at conservation and subsidence control — but coverage is district by district, not statewide, and a district’s permit rules for one aquifer can look nothing like the rules next door. A buyer won’t find any of that summarized on a standard disclosure form; it has to be looked up separately, by county and by district, before relying on the property’s water.

The general Seller’s Disclosure Notice that Texas home sales use, required under Property Code Section 5.008, is built for a residence — its questions cover roofs, HVAC systems, and termite history — and most raw acreage sales without a dwelling don’t go through that form at all. Where it does apply, the form asks whether any part of the property sits inside a groundwater conservation or subsidence district, according to the Texas Real Estate Research Center, but that single checkbox item is the extent of what a residential-style disclosure covers on groundwater.

What about surface water — a creek, river, or pond on the property?

Surface water in Texas belongs to the state, not to the adjoining landowner, and using it for anything beyond household or livestock needs generally requires a permit from the Texas Commission on Environmental Quality. The Texas Real Estate Research Center notes that landowners along a stream retain only limited riparian rights: household and livestock use. Most other riparian claims were folded into the state’s permit-based system after the 1967 Water Rights Adjudication Act. If a listing advertises irrigation rights, a stocked lake fed by diverted water, or any commercial water use tied to a creek or river, that use should be backed by a specific TCEQ water right, not assumed from the fact that the water crosses the property.

None of that gets disclosed automatically either. A seller isn’t required to hand over a copy of a TCEQ water right or confirm one doesn’t exist; a buyer who cares about surface water use has to ask for the permit number and verify it independently.

Is there a separate notice for water and sewer service, or is that the same thing?

It’s a different requirement entirely, and buyers often confuse the two because both show up under “water” in a Texas closing packet. Texas Water Code Section 13.257 requires a seller to give written notice, before the contract becomes binding, when real property sits inside a certificated service area of a water or sewer utility — a notice that the property may face special construction costs or delays before that utility actually connects service. It says nothing about who owns the water under the ground or in a stream; it’s a utility-availability warning, closer in spirit to a notice about road access than to anything involving water rights.

The two statutes also carry different penalties. Under Section 5.019, a late reservoir notice gives the buyer a short window to walk away. Under Section 13.257, a purchaser who didn’t get the utility notice can instead recover damages — according to the statute, either the buyer’s actual costs tied to the purchase plus interest and attorney’s fees, or a flat amount up to $5,000 plus attorney’s fees, whichever the buyer elects. A buyer who gets a “water notice” attached to a Texas contract should read which statute it cites before assuming it says anything about water rights at all.

What should a Texas land buyer actually do with all of this before closing?

The practical answer is to treat Section 5.019 as one specific box to check, not the whole picture. If the property adjoins a reservoir that looks large enough to meet the 5,000 acre-foot threshold, confirm the notice was delivered and read it before the contract goes binding — and if it wasn’t delivered, remember the seven-day clock starts running the moment any source tells the buyer about the fluctuation. For everything else — groundwater district coverage, well records, surface water permits — the buyer’s due diligence has to fill the gap the disclosure system leaves open, the same way it would when reviewing any other red flag in a vacant land purchase agreement or confirming a parcel is actually buildable before closing.

That research is straightforward even if it isn’t automatic: a groundwater conservation district lookup by county, a well log request from the seller, and a TCEQ water rights search for any surface water use cover most of what a buyer needs. None of it requires a specific number of deals closed or an average sale price to explain — just confirming, before the contract is binding, what water rights actually attach to the acreage and what a local district might restrict later.

If the roles are reversed and the water questions are the reason a Texas landowner wants out of a parcel rather than into one — old irrigation rights nobody’s used in years, a GCD permit that’s more trouble than it’s worth, a lake lot with fluctuating shoreline they never visit — AMM Land Sales makes cash offers on land across Texas directly to owners, pays closing costs, and settles any delinquent property taxes from the proceeds at closing.
