OPINION
COCHRAN, J.,
delivered the opinion of the Court,
joined by MEYERS, PRICE, JOHNSON, and HOLCOMB, JJ.
A jury convicted appellant of discharging raw sewage from a broken septic tank line on his property into or adjacent to water in the state, in violation of Water Code section 26.121(a)(1).1 We must determine whether the trial judge, when taking judicial notice of a Texas water pollution case entitled American Plant Food v. State,2 properly restricted her comments to notice of adjudicative facts, or whether she improperly commented on the weight of the evidence before the jury.3 The court of appeals held that there was no error, either in taking judicial notice of American Plant Food, or in the substance of the instruction.4
We disagree. Because we find that the trial judge did not judicially notice an adjudicative fact, but rather directly addressed the jury on the application of a point of law, immediately before the parties rested and before she read the charge to the jury, we hold that the trial judge committed [607]*607error by commenting on the weight of the evidence. Although we find that the trial judge’s interpretation of our holding in American Plant Food was essentially correct, it was for the jury to decide if the drainage ditch water in this case constituted “water in the State.” Accordingly, we reverse and remand the case to the court of appeals to conduct a harm analysis.
I.
In June 1998, the Harris County Health Department received a nuisance complaint concerning trash, junk, and debris strewn about appellant’s property. While investigating the complaint, Harris County Health Department workers discovered a serious sewage leak on appellant’s property. Specifically, they found a large puddle of raw sewage adjacent to a round concrete lid, the kind that typically covers septic tanks. The workers also discovered a broken septic pipe that was discharging human waste and toilet paper from appellant’s trailer directly onto the ground nearby. During rainfall, a shallow trench tunneled this waste from appellant’s property into a nearby county drainage ditch. This normally dry drainage ditch, in turn, diverted run-off into Coal Creek, which led to White Oak Bayou, then to Buffalo Bayou, the Houston Ship Channel, and ultimately into Galveston Bay.
Immediately before the State rested and closed its case-in-chief, the trial judge heard objections to the charge outside the jury’s presence. Defense counsel stated:
MR. Mewis: I object to the conclusion of the cases — of judicial knowledge section. I object to that being as a comment on the way to [sic ] the evidence and also not an item that can be judicially noticed. I object because it’s a issue of fact for the jury to determine. That’s my objection.
Me. Bily: And for the record I was requesting a judicial instruction.
The jury re-entered and the trial judge asked whether the State had any further witnesses or evidence to present. The prosecutor responded:
MR. Bily: Judge, we have no further witnesses but we would request the Court take judicial notice of the Court of Criminal Appeals [sic] holding in [American Plant Food v. State, 587 S.W.2d 679].
The CouRT: Any objection from the defense?
MR. Mewis: Same objection I think I already have it on the record.
MR. Bily: Judge, we request the holding in regard to a drainage ditch.
The CouRT: Ladies and gentlemen, the Court will take judicial notice that the Texas Court of Criminal Appeals in a 1979 case entitled American Plant Food versus the State of Texas. That Court of Criminal Appeals found that in that case where evidence showed that a pollutant escaped from the premises onto an adjacent field that formed a large pool and then flowed into a drainage ditch that in that case the drainage ditch was one of the types of surface water the legislature sought to protect under the Water Code Act.
Ladies and gentlemen of the jury, you are instructed that you may but are not required to exempt [sic] as conclusive any fact judicially noticed. Anything further from the State?
MR. Bily: No.
The Court: State rests and close?
Mr. Bily: Rest and close.
The CouRT: Defense have anything further?
MR. Mewis: Nothing further.
[608]*608The trial judge then read the written charge to the jury. The jury charge tracked the language of the indictment and the Water Code statute.5 The application paragraph stated, in part:
Therefore, if you believe from the evidence beyond a reasonable doubt, that the defendant, John Watts, [did] ... unlawfully, intentionally, or knowingly discharge or allow the discharge of a waste and pollutant, namely sewage[,] into or adjacent to water in the state, namely, a drainage ditch located near 9134 West Little York[,] that caused or threatened to cause water pollution, said discharge not being in strict compliance with all the required permits or with an order issued or rule adopted by the appropriate regulatory agency ... or if you believe from the evidence beyond a reasonable doubt that the defendant [did] ... unlawfully, intentionally, or knowingly discharge or allow the discharge of a waste or pollutant, namely sewage, from a point source, namely a septic tank line, in violation of Water Code Section 26.121(a)(1), prohibiting the unauthorized discharge of sewage into or adjacent to any water in the state, you will find the defendant guilty.
During the State’s closing argument, the prosecutor reviewed his burden of proof with the jury. Regarding the element, “water in the state,” he told the jurors:
MR. Bily: ... Really I’m not going to argue about the water in the State because I think when you get back there and look at the definition and you remember a hydrologist came in here and testified as to the water in the State and you read the definition and you see it includes all beds and banks of all water course, I think it’s pretty set. And judicial notice of the fact that another Court, a hirer [sic ] Court, the highest Court in Texas has held that drainage ditches are entitled to the protection of this statute. I think that’s pretty clear.
MR. Mewis: Objection, your Honor. I have to object. That’s a misstatement you said, “a drainage ditch in that case.”
The Court: Sustained.
Mr. Bily: Drainage ditch in that case. Well, you know that now a drainage ditch in cases can be accepted as a water in the State.
The jury returned a guilty verdict, and the trial judge sentenced appellant to one year in the Harris County Jail, probated for two years, and a $10,000 fine ($9,000 probated).

The Court: Sustained.
Mr. Bily: Drainage ditch in that case. Well, you know that now a drainage ditch in cases can be accepted as a water in the State.
The jury returned a guilty verdict, and the trial judge sentenced appellant to one year in the Harris County Jail, probated for two years, and a $10,000 fine ($9,000 probated).
Appellant appealed and argued that the trial judge erred, in the first place, by taking judicial notice of this Court’s holding in American Plant Food Corp. because: 1) statements contained in judicial opinions are not a proper subject for judicial notice; and 2) additionally, the instruction constituted an improper comment on the weight of the evidence. Second, appellant contended that the trial judge misread the case, and thus compounded her first error by misstating the law to the jury.
The court of appeals disagreed, holding that there was no error in the trial judge’s taking judicial notice of this Court’s hold-[609]*609mg in American Plant Food Corp.6 It stated that it is “a rudimentary concept of our system of jurisprudence ... that a lower court must yield to [a] superior court’s interpretation of a statute.”7 The court of appeals acknowledged that it would be error, “when a superior court’s opinion is related to a particular scenario or fact situation, ... for a trial court to impose the holding in a factually dissimilar case.”8 Here, however, it said, “the undisputed facts [were] similar to those in American Plant Food.”9
The court of appeals explained that, in American Plant Food, “the issue presented to [the Court of Criminal Appeals] was whether a stagnant drainage ditch that flowed only intermittently” constituted “ *water in the state’ ” for purposes of the statute.10 The court of appeals explained that this Court had held that the statute did not distinguish between “ ‘perennial and intermittent streams[,]’ ” and that therefore, “ ‘drainage ditch water [was] one of the types of surface water [that] the Legislature sought to protect.’ ”11
Turning to the facts of the instant case, the court of appeals noted that appellant himself testified that the drainage ditch in question drained a large area, including his property.12 Presumably, from this evidence, the court of appeals inferred that there was no dispute: 1) that a county drainage ditch existed near appellant’s property; and 2) that the drainage ditch intermittently contained water run-off from appellant’s property and the surrounding area. Therefore, it concluded, any water entering that ditch constituted “waters of the state,” as a matter of law, and thus the trial judge did not err when she took judicial notice of this Court’s interpretation of a statute.13 It also held that, because the judge’s statement tracked the applicable statutory language and this Court’s interpretation of it in American Plant Food, the trial judge did not comment on the weight of the evidence, but gave an accurate statement of the law, that a drainage ditch falls under the statutory definition of “water within the state.”14
II.
We must distinguish between a trial judge taking judicial notice of adjudicative facts, and taking judicial notice of the law. We must further distinguish between taking judicial notice of the law,15 outside the jury’s presence, and instructing the jury regarding a specific application of law to fact.
When a trial judge takes judicial notice of adjudicative facts, he authorizes the fact-finder to accept the truth or existence of those specific facts without requir[610]*610ing formal proof.16 Adjudicative facts which may be judicially noticed are relevant to the ultimate issue in dispute, but are not themselves the subject of any controversy. Such facts may be judicially noticed only if they are not subject to reasonable disagreement.17 For instance, in a criminal case, for purposes of establishing venue, a trial or appellate judge might take judicial notice that the City of Austin, where the offense allegedly occurred, is located in Travis County.18 The parties might dispute the fact that the offense occurred at all, or if it did, that it occurred in Austin, but not that the City of Austin is in Travis County. To insist that a party prove the commonly known (or at least, readily ascertainable) fact of the city’s location would waste limited judicial resources and defy common sense.19 Rule 201 of the Texas Rules of Evidence governs judicial notice of these adjudicative facts.
Judicial notice of state law, in contrast, is not governed by Article II,20 but by individual statutes and cases. Texas courts can, of course, take judicial notice of the laws of this State.21 In determining the content, scope, and meaning of the applicable law, the judge may look to statutes, rules, case law, and legislative history. The judge is not restricted in his investigation into the content or applicability of the laws of the forum; he may make an independent search for persuasive data or rest content with the materials the parties provide.22
A trial judge might, for example, be requested to rule on a defendant’s motion for directed verdict, alleging that the State had failed to prove an essential element of its case — that certain sewage running into a drainage ditch constituted “water in the state.” In that case, the trial judge might well take judicial notice of the existence, content, and applicability of one of this Court’s decisions, such as American Plant Food, in ruling upon that motion for directed verdict. That is a perfectly ap[611]*611propriate exercise of judicial notice of law. But this type of judicial notice is always taken outside the presence of the jury.23
The jury, however, determines questions of fact in light of the law as it is finally determined and given to it by the court in the written jury charge.24 All of the applicable law is contained within that written jury charge. The jury charge does not contain excerpts from judicial decisions or any statements that an appellate court has held that proof of “X” fact fulfills “Y” legal requirement.
III.
In this case, the trial judge directly addressed the jury at a crucial time in the proceedings and instructed it as to this Court’s interpretation of the pertinent Water Code statute in a prior case.25 The trial judge’s instruction gave a fairly accurate,26 if somewhat simplified, [612]*612account of this Court’s holding in American Plant Food. In that case, we held:
Viewing the evidence in the light most favorable to the verdict, we hold it sufficient to prove a violation of Section 21.552, supra, as alleged in the information. The evidence shows that the pollutant escaped from American Plant Food’s premises onto the adjacent field. It formed a large pool and then flowed into a drainage ditch. This drainage ditch contained not only waste from the factory, [sic] another stream of water also flowed into it from the northeast. The water in this stream had a neutral pH of 7 until it combined with the very acidic solution discharged by appellant. The water polluted was not merely that in the pool formed by the discharge but all the water in the ditch and that flowing into it. It is readily apparent from the above broad definitions that this drainage ditch water is one of the types of surface water the Legislature sought to protect, and we so hold.27
We did not hold that all drainage ditches or all materials that flow into a drainage ditch necessarily constitute water in the state, as a matter of law. Our holding stated only that under the specific facts of that case, that particular drainage ditch water met the statutory definition. Thus, the evidence in that particular case was sufficient to support the jury’s verdict. The conclusion, however, that some drainage ditch water may be the type of surface water that the Legislature sought to protect in the Water Code, is not a notorious or easily-verifiable adjudicative fact subject to judicial notice under Texas Rule of Evidence 201. By drawing attention to our holding of American Plant Food shortly before the jury began its deliberations, the trial judge may have inadvertently communicated an opinion concerning the weight of the evidence in this case.28
The State argues that the issue of whether a drainage ditch is water “should no longer be litigated in every case involving a discharge into or adjacent to a drainage ditch. The issue has been decided as a matter of law and is clearly a holding upon which the State is entitled to rely.” [613]*613The State would be correct if the Water Code explicitly stated: “a drainage ditch is water.” It does not.29
We find that the trial judge did not judicially notice an adjudicative fact, but rather directly addressed the jury on the specific application of law to facts in a different judicial decision, immediately before the parties rested and before she read the charge to the jury. We therefore hold that the trial judge committed error by commenting on the weight of the evidence. Accordingly, we reverse the judgment of the court of appeals and remand the case to that court for it to conduct a harm analysis.
