                                  Argued September 19, 2019


     JUSTICE BUSBY delivered the opinion of the Court, in which JUSTICE GUZMAN, JUSTICE
LEHRMANN, JUSTICE BOYD, JUSTICE DEVINE, and JUSTICE BLACKLOCK joined.

       JUSTICE GREEN filed a dissenting opinion, in which CHIEF JUSTICE HECHT joined.

       JUSTICE BLAND did not participate in the decision.


       This case is a title dispute between the State and a private landowner over portions of the

submerged bed of Lone Oak Bayou, a navigable body of water located near the Gulf of Mexico.

The owner’s predecessor bought 160 acres of land from the State that included the bayou’s bed,

and the Legislature later passed a statute—the Small Bill—validating conveyances that included

“the beds . . . of watercourses or navigable streams.” The Commissioner of the General Land

Office contends this statute did not validate the owner’s title to the bayou’s bed because the term
“navigable stream” refers only to portions of the stream not subject to the ebb and flow of the tide,

and the tide enters the bayou.

       We disagree with the Commissioner and conclude that the Legislature gave all buyers of

submerged streambeds what they paid for. From the early days of the Republic of Texas, the term

navigable stream has been defined without drawing a distinction based on the tide: it includes

portions of the stream both above and below the tide line. The government holds title to the beds

of navigable streams in trust for the public, and the Legislature can convey those beds to private

owners. It did so expressly in the Small Bill.

       We agree with our dissenting colleagues that there are key differences in the legal rules

governing ownership of submerged land above and below the tide line. All agree on how those

rules apply here: the State owns the beds of navigable streams on both sides of the line. The only

issue in dispute is what land was included when the Legislature chose to validate certain

conveyances of state-owned “beds . . . [of] navigable streams.” Because the plain and settled

meaning of the statutory term “navigable stream”—under both the civil and the common law—

includes portions of the stream below the tide line, the beds underlying those portions were

properly conveyed.

       The Commissioner also asserts that Lone Oak Bayou is not a navigable stream for reasons

apart from the tide, so the Small Bill does not apply in any event. We conclude there are factual

disputes to be resolved regarding whether the bayou is a navigable stream within the scope of the

statutory conveyance. We therefore reverse the summary judgment in favor of the owner and

remand for further proceedings.




                                                 2
                                                 BACKGROUND

         The Lone Oak Club owns an approximately 160-acre tract in Chambers County that

includes land submerged under the Lone Oak Bayou. 1 The bayou is an inlet; its mouth is located

in the survey’s northwest corner, near Trinity Bay. Due east of the tract are the bayou’s

headwaters, from which rainwater runoff drains along the bayou’s length, through a narrow and

winding passage, and into the bay. The parties agree that the bayou is navigable and its waters are

“tidally influenced”—an imprecise term not recognized in Texas property law that the parties use

to describe waters below the line of mean high tide.

         The tract was patented in 1872 to Sophronia Barrow, who purchased it from the Governor

of Texas. The patent to Barrow describes, crosses, and includes Lone Oak Bayou. Barrow paid

for 160 acres of land, and it is undisputed that the patent only contains that much land if it includes

a portion of the bayou’s bed. Specifically, the patent—also known as the “Barrow Survey”—

grants

         to Sophronia Barrow, her heirs and assigns Forever, One hundred and Sixty (160)
         acres of Land situated and described as follows In Chambers County on the East

                                                         3
Through a regular chain of title, the Club acquired the Barrow Survey in 2002 3 to establish a

recreational area for hunting and fishing, and it has consistently used the property for that purpose.

        The dispute in this case arose when members of the public began hunting and fishing in

portions of the bayou within the Barrow Survey. Although the Club takes no issue with the public

accessing water in the bayou, as it concedes the State holds title to the water, sand, and gravel in

public trust, the Club contests the public’s right to come into contact with the bayou’s submerged

bed. Because the Barrow Survey includes the land under the bayou’s water, the Club contends,

trespass occurs when individuals set foot on or cause shotgun pellets to contact the bayou’s bed.

        The General Land Office (GLO) 4 became involved in this dispute in late 2008, when an

evicted hunter asked for its opinion on the “extent of State ownership in Lone Oak Bayou and the

attendant waterways and their beds adjacent to and flowing through” the Club’s property. In

March 2009, two GLO staff members conducted an on-site visual inspection and “observed the

tide coming in and rising” on the bayou and its connected lakes. The director of the surveying

division subsequently rendered an opinion that the disputed areas are “State owned submerged

lands,” the “waters are tidally influenced, public, waterways,” and the “boundary between the State

and private ownership is the line of [mean high water].” After meeting with GLO staff, the Club

received a letter reflecting the agency’s official opinion on the matter.

        In this letter, the GLO asserted State ownership of “any part of Lone Oak Bayou and the

attendant waterways . . . which are located below the line of mean high water.” In support of this



        3
           The Club’s chain of title is undisputed. The patent to the Barrow Survey has never been challenged,
cancelled, or forfeited.
        4
          The GLO is a constitutionally created agency empowered to supervise and manage state-owned lands. TEX.
CONST. art. XIV, § 1.



                                                       4
conclusion, the GLO explained that due to the bayou’s “tidal influence,” its submerged lands were

never properly conveyed from State ownership:

         While conducting the inspection of your property, staff observed that Lone Oak
         Bayou and the attendant waterways adjacent to and flowing through the property
         are tidally influenced. It is fundamental Texas law that tidally influenced
         waterways and their beds are owned by the sovereign, and have been so even before
         Texas was a State. These waterways and the beds beneath them remain the property
         of the State . . ., unless a clear and specific conveyance by the legislature changes
         the ownership.

         The parties agree that the bayou’s waters are “tidally influenced” and that the 1872

conveyance of the bayou’s submerged lands was initially invalid, though they give different

reasons for this opinion. 5 The crux of the parties’ dispute is whether a subsequent “legislative

conveyance,” the 1929 Small Bill, validated the portion of the 1872 patent covering submerged

lands under “tidally influenced” waters.

         The Small Bill provides, in short, that “[a]ll patents to and awards of lands lying across or

partly across water courses or navigable streams and all patents and awards covering or including

the beds or abandoned beds of water courses or navigable streams or parts thereof . . . are hereby

confirmed and validated” if they meet certain other conditions. TEX. REV. CIV. STAT. art. 5414a(1)

(1929). The State of Texas “relinquishes, quit-claims[,] and grants to patentees and awardees and

their assignees” such patents and awards. Id. art. 5414a(2).

         In its letter to the Club, the GLO maintained that the Small Bill did not validate patents to

submerged lands underlying “tidally influenced waterways.” Specifically, the GLO stated:

         Staff could find no evidence of a legislative conveyance of the waterways adjacent
         to and flowing through your property. We understand that you believe the Small

         5
          The dissent concludes that this conveyance of submerged land was invalid because the Governor, not the
Legislature, issued the patent. Post at __ (Green, J., dissenting). Because we hold that the Legislature later validated
the conveyance in the Small Bill, we do not address this issue.



                                                           5
         Bill . . . applies to the navigable waterways flowing through your property and that
         the beds of the navigable waterways therefore belong to the upland owner. The
         GLO, however, has always held to the opinion that the Small Bill does not apply to
         tidally influenced waterways.

The GLO has maintained this position throughout the litigation.

         The Club disagreed. Believing the Small Bill covered submerged land under tidally

influenced navigable streams and water courses, the Club petitioned the GLO to change its stance.

When these efforts proved unsuccessful, the Club brought an ultra vires trespass-to-try-title suit

against the GLO Commissioner. 6 In its petition, the Club alleged: the GLO had no right to cloud

its title to the land; the Club was the rightful owner of all 160 acres within the Barrow Survey,

including land submerged under Lone Oak Bayou; and the State had no right to permit members

of the public to set foot on that land. Both parties moved for summary judgment.

         The Club argued, as it does here, that the plain and unambiguous language of the Small

Bill applies to lands submerged beneath tidally influenced navigable streams and watercourses.

The Club argued that as a patent crossing a “water course” or “navigable stream,” the Barrow

Survey fit the Small Bill’s requirements. The Small Bill thus validated the patent and—being

necessary to reach the intended acreage—all of the submerged beds within its boundaries. The

Commissioner’s motion echoed the GLO letter, arguing the Small Bill conveyed only submerged

beds underlying non-tidally influenced streams.

         The trial court denied the Commissioner’s motion and granted summary judgment for the

Club.    Concluding that the Small Bill validated patents to and awards of submerged beds




          6
            The parties argued about the propriety of this ultra vires action in the courts below. They have not raised
the issue in this Court.



                                                          6
underlying tidally influenced water courses and navigable streams, the trial court held that the Club

owned the bayou’s beds within the Barrow Survey in fee simple. The Commissioner appealed.

        In the court of appeals, the Commissioner again argued that the Small Bill did not convey

title to land submerged under tidally influenced water. 7 546 S.W.3d 766, 777–78 (Tex. App.—

Houston [1st Dist.] 2018). The court of appeals disagreed, holding the plain language of the Small

Bill and its “historical purpose” indicate “the term ‘watercourse or navigable stream’ as used in

the Small Bill does not exclude watercourses or navigable streams that are ‘tidally affected.’” Id.

at 779. Because the Barrow Survey met the Small Bill’s criteria for validation, the court of appeals

affirmed the trial court’s summary judgment in favor of the Club.                       Id.    We granted the

Commissioner’s petition for review.

                                                   ANALYSIS

        In this Court, the parties continue to dispute whether the Small Bill validated patents of

land submerged under tidally influenced water courses and navigable streams. The Commissioner

argues it did not; the Club contends it did. Before diving into the analysis, we address a few

preliminary matters.

        First, recognizing that courts’ decisions have not always been clear in this area, we begin

by explaining the terms we use in this opinion. The Small Bill addresses “navigable streams” and

“water courses,” while the 1837 Navigable Stream Statute, which we also discuss, uses the terms

“navigable water course,” “stream,” and “navigable stream.” For ease of reference, we use the

term “navigable stream” when referring generally to all three bodies of water just mentioned,


        7
           The Commissioner also argued the Club’s ultra vires trespass-to-try-title claim was improper. 546 S.W.3d
at 772–75. The court of appeals rejected this argument, id. at 775, and the Commissioner has not sought our review
of the issue.



                                                        7
though these bodies could encompass different areas depending on the geographic features present.

See State v. Bradford, 50 S.W.2d 1065, 1072 (Tex. 1932).

        Second, “tidal influence” is an imprecise term not recognized in Texas law. Generally, in

determining the boundary between State and private ownership of land along the seashore, Texas

looks to the relevant tide line in effect at the time of the grant in question. For grants under the

Mexican civil law, applied in Texas until January 1840, the higher high tide line determines State

and private boundaries. Luttes v. State, 324 S.W.2d 167, 191 (Tex. 1958). For grants under the

English common law, applied from January 1840 onward, we look to the line of mean high tide.

Id. State ownership generally begins below the relevant tide line. Heard v. Town of Refugio, 103

S.W.2d 728, 733 (Tex. 1937). The Barrow Survey was patented in 1872, so the applicable line

here is that of mean high tide. Luttes, 324 S.W.2d at 191.

        As we shall explain, however, the tide line does not establish the dividing line between

State and private ownership of land under navigable streams that adjoin the sea. Rather, the State

holds title to the land under such streams both above and below the tide line in trust for the public.

See Bradford, 50 S.W.2d at 1070 (“If it be determined that the river is navigable, then the title to

the land in the river bed belongs to the state . . . .”). Texas law permits the Legislature to convey

public land under both streams and the sea so long as the conveyance meets certain requirements.

Id. at 1076; Coastal Indus. Water Auth. v. York, 532 S.W.2d 949, 951 (Tex. 1976) (noting the

Legislature granted the City of Houston the bed of the Houston Ship Channel, a navigable stream

partially below the tide line).

        These considerations help us frame the issue presented more precisely. As we have

explained, the Small Bill “confirmed and validated” “patents to and awards of lands” that include



                                                  8
the “beds [of] . . . navigable streams.”     The parties agree that this language conveyed the

submerged beds of navigable streams above the tide line, but they dispute whether it had the same

effect below the line. Thus, the issue we must decide is: under the Small Bill, does a “navigable

stream” exist only above the tide line? In other words, does a navigable stream no longer bear that

name below the tide line, such that the Small Bill does not validate a conveyance of its bed?

       Because the Small Bill was enacted to cure title defects caused by the 1837 Navigable

Stream Statute, we conclude the meaning of navigable stream in each statute must be the same.

Under the Mexican civil law, in effect when the Navigable Stream Statute was passed, the term

navigable stream encompassed portions of the stream above as well as below the tide line. We

therefore agree with the trial court and court of appeals that the Small Bill validates patents

conveying the submerged beds of navigable streams, whether above or below the tide line.

I.     Standard of review

       “We review summary judgments de novo, taking as true all evidence favorable to the

nonmovant, and indulging every reasonable inference and resolving any doubts in the nonmovant’s

favor.” Barbara Techs. Corp. v. State Farm Lloyds, 589 S.W.3d 806, 811 (Tex. 2019). When

both parties move for summary judgment on the same issue, we consider the evidence presented

by both parties and determine all questions presented. Id.

       A question of statutory construction is a legal one, which we also review de novo. Atmos

Energy Corp. v. Cities of Allen, 353 S.W.3d 156, 160 (Tex. 2011). Our objective in construing a

statute is to give effect to the Legislature’s intent, looking first to the “plain and common meaning

of the statute’s words.” MCI Sales & Serv., Inc. v. Hinton, 329 S.W.3d 475, 500 (Tex. 2010). We




                                                 9
may also consider the “circumstances under which the statute was enacted[] and the consequences

of a particular construction.” Atmos Energy, 353 S.W.3d at 160.

       In discerning a statute’s plain and common meaning, “[w]e presume the Legislature

enacted the statute ‘with complete knowledge of the existing law and with reference to it.’” In re

Bridgestone Ams. Tire Operations, LLC, 459 S.W.3d 565, 572 (Tex. 2015) (quoting Acker v. Tex.

Water Comm’n, 790 S.W.2d 299, 301 (Tex. 1990)). When “a legislature has used a word in a

statute in one sense and with one meaning, and subsequently uses the same word in legislating on

the same subject-matter,” its meaning in the subsequent statute will ordinarily be the same.

Colorado County v. Staff, 510 S.W.3d 435, 452 (Tex. 2017). This rule applies when the words or

phrases at issue are “substantially the same” and holds particular force where their meaning in the

earlier act is clear or has been adjudicated. Id. at 452 & n.70 (citing L & M-Surco Mfg., Inc. v.

Winn Tile Co., 580 S.W.2d 920, 926 (Tex. App.—Tyler 1979, writ dism’d)).

II.    Applicable law

       The law governing ownership of submerged lands in Texas has a long history. We begin

in 1836: the year Texas achieved independence from Mexico. Hans W. Baade, The Historical

Background of Texas Water Law—A Tribute to Jack Pope, 18 ST. MARY’S L.J. 1, 29 (1986). In

1836, the Republic of Texas ratified its first constitution. Manry v. Robison, 56 S.W.2d 438, 443

(Tex. 1932). This constitution retained “all laws then in force in Texas, and not inconsistent with

the Constitution,” including the Mexican civil law and the laws of Coahuila and Texas, formerly

a Mexican state. Motl v. Boyd, 286 S.W. 458, 465 (Tex. 1926). Such laws were to remain in effect

“until declared void, repealed, altered, or expired by their own limitation.” Id.




                                                 10
        In December 1837, the Congress of the Republic of Texas passed the Navigable Stream

Statute. Id. at 466. That statute prescribes how lands “lying on navigable water courses” and

streams should be surveyed. Act approved Dec. 14, 1837, 2d Cong., R.S., §§ 21, 42, 1837 Repub.

Tex. Laws 62, 70, reprinted in 1 H.P.N. Gammel, The Laws of Texas 1822–1897, at 1412 (Austin,

Gammel Book Co. 1898) [hereinafter Act approved Dec. 14, 1837]. Specifically, the Navigable

Stream Statute provides that survey lines may not cross navigable water courses and streams:

        That all lands surveyed for individuals lying on navigable water courses, shall front
        one half of the square on the water course, and the line running at right angles with
        the general course of the stream, if circumstances of lines previously surveyed
        under the laws will permit, and all others not on navigable water courses shall be
        square if previous lines will permit; and under no circumstances shall any one grant
        be located in more than two surveys.

Id. The statute defines “navigable streams” as “all streams of the average width of thirty feet . . . so

far up as they retain that average width.” Id. § 42. In January 1840, Texas adopted the English

common law, but only “so far as it [was] not inconsistent with the Constitution or the Acts of

Congress [then] in force,” which included the Navigable Stream Statute. Act approved Jan. 20,

1840, 4th Cong., R.S., § 1, 1840 Repub. Tex. Laws 1, 3, reprinted in 2 H.P.N. Gammel, The Laws

of Texas 1822–1897, at 177 (Austin, Gammel Book Co. 1898) [hereinafter Act approved Jan. 20,

1840]; see also Motl, 286 S.W. at 465.

       In Motl v. Boyd, this Court shed further light on the meaning of “navigable stream” under

the Navigable Stream Statute. 286 S.W. at 467. We held that “[a] water course, river, or stream

consists of a bed, banks, and a stream of water” with an average width of 30 feet across the “entire

bed of the stream.” Id.

       Three years after Motl, the Legislature passed the Small Bill, validating certain “patents to

and awards of lands” that had violated the Navigable Stream Statute by crossing “navigable


                                                  11
streams.” TEX. REV. CIV. STAT. art. 5414a(1)–(2). In State v. Bradford, we recognized that

although “lands underlying navigable waters are held in trust by the state for the use and benefit

of all the people,” the Legislature has authority to “validate the titles to the land for which patents

and awards have issued.” 50 S.W.2d at 1069, 1077. We held that the Legislature did so in the

Small Bill, in compliance with our Constitution, when it “decided to retain the consideration

received for the land and confirm to the landowners that which they had already bought and paid

for or for which the state held their outstanding obligations.” Id. at 1077.

III.    The Small Bill validates patents conveying the beds of navigable streams, whether
        above or below the tide line.

        The Small Bill does not define “water course” or “navigable stream.” But as noted, when

the Legislature uses the same word or phrase again in legislating on the same subject matter, the

meaning of that word or phrase ordinarily remains the same. Colorado County, 510 S.W.3d at 435

& n.70. Here, though the Navigable Stream Statute and Small Bill use slightly different wording

in describing the bodies of water within their reach, the terms at issue are “substantially the same.”8

Compare TEX. REV. CIV. STAT. art. 5414a (addressing water courses and navigable streams), with

Act approved Dec. 14, 1837, §§ 21, 42 (addressing navigable water courses, streams, and

navigable streams). Our previous cases have concluded that the Small Bill and Navigable Stream

Statute affect the same subject matter, as the Small Bill validates surveys made invalid by the

Navigable Stream Statute. 9 We therefore look to the meaning of “navigable stream” in the

Navigable Stream Statute in order to determine its meaning in the Small Bill.

         A.       Interpreted in light of the civil law, the Navigable Stream Statute applies to
                  portions of “navigable streams” below the tide line.

         The Navigable Stream Statute defines “navigable streams” as “all streams of the average

width of thirty feet . . . so far up as they retain that average width.” Act approved Dec. 14, 1837,

§ 42. Neither this definition nor the law in force at the time of its enactment indicate that the tide

plays any role in setting the boundaries of a navigable stream.

         Because we presume the Legislature acted with knowledge of existing law, we construe

the Navigable Stream Statute “in connection and in harmony with [that] law, and as a part of a

general and uniform system of jurisprudence.” McBride v. Clayton, 166 S.W.2d 125, 128 (Tex.

1942). As discussed, the Republic of Texas followed the civil law of Mexico when the Navigable

Stream Statute was enacted. Bradford, 50 S.W.2d at 1074. To decide whether the statute includes

portions of navigable streams below the tide, we therefore examine the civil-law meaning of the

term navigable stream. See McBride, 166 S.W.2d at 128.

         The civil law recognized two classes of streams: rivers and creeks. See Wallace Hawkins,

Title to River Beds in Texas and Their Boundaries, 7 TEX. L. REV. 493, 508 (1929). Navigable

streams generally fall within the category of civil-law “rivers,” defined as “a mass of water united

between two banks, which runs perpetually from time immemorial.” FREDERIC HALL, THE LAWS

OF MEXICO: A COMPILATION AND TREATISE §                  1406 (1885) [hereinafter HALL’S MEXICAN LAWS].

The beds of these perennial rivers were owned by the state. Hawkins, supra, at 508–09. Texas

courts have since conflated the terms river, water course, and stream, recognizing their similar

geological features. Motl, 286 S.W. at 467 (“A water course, river, or stream consists of a bed,


(noting that if the river in question was deemed a “statutory navigable stream,” then “the title to the land in the river
bed belongs to the state, subject to the provisions of the Small Bill”).



                                                          13
banks, and a stream of water.”); see also Hawkins, supra, at 510–11 (explaining that the Navigable

Stream Statute’s drafters intended to equate water course and stream with civil-law rivers).

       “[I]n the language of the civil law,” rivers existed both above and below the tide line, and

the “navigable” character of some rivers connoted only that they were “capable of being

navigated”—i.e., of “admitting floats.” JOSEPH ANGELL, TREATISE ON THE RIGHT OF PROPERTY IN

TIDE WATERS AND IN THE SOIL AND THE SHORES 79 (2d ed. 1847) [hereinafter TREATISE ON TIDE

WATERS]. The civil law acknowledged that rivers “follow their course to the sea.” HALL’S

MEXICAN LAWS § 1388. Rather than defining rivers to exclude tidal influence, the civil law

recognized that they continue below the tide: “A bank is the margin and shore of the sea or river,

that is, the place or space which their waters cover at the time when they swell most with their

periodical flood-tide and ebb-tide, whether in winter or summer, without going out of their bed.”

Id. at § 1409 (emphasis added).

       Thus, under the civil law, navigable streams and other rivers extended both above and

below the tide. The Republic Congress included its own definition of navigable stream in the

Navigable Stream Statute, but nothing in that definition—which focuses on the stream’s width—

indicates that Congress modified the term’s civil-law meaning with respect to the tide.

Accordingly, we hold that in light of the civil law, the Navigable Stream Statute prevents survey

lines from crossing “navigable streams” both above and below the tide line. See Allen Sales &

Servicecenter, Inc. v. Ryan, 525 S.W.2d 863, 866 (Tex. 1975) (“[S]tatutes are presumed to be

enacted by the legislature with full knowledge of the existing condition of the law and subject

thereto unless the contrary is clearly indicated.”).




                                                  14
        B.      Because the Small Bill validates surveys invalidated by the Navigable Stream
                Statute, it also covers the beds of “navigable streams” below the tide line.

        Because the Small Bill refers to and validates the same surveys originally rendered invalid

by the Navigable Stream Statute, an identical interpretation of the term navigable stream as used

in the Small Bill is appropriate. “It is presumed in construing statutes that several acts or provisions

relating to the same subject [are] intended to be consistent and to operate in harmony,” and nothing

in the Small Bill rebuts this presumption. Connors v. Connors, 796 S.W.2d 233, 237 (Tex. App.—

Fort Worth 1990, writ denied).

        The Small Bill provides in pertinent part:

        Sec. 1. All patents to and awards of lands lying across or partly across water courses
        or navigable streams and all patents and awards covering or including the beds or
        abandoned beds of water courses or navigable streams or parts thereof, which
        patents or awards have been issued and outstanding for a period of ten years from
        the date thereof and have not been cancelled or forfeited, are hereby confirmed and
        validated.

        Sec. 2. The State of Texas hereby relinquishes, quit-claims and grants to patentees
        and awardees and their assignees all of the lands, and minerals therein contained,
        lying across, or partly across watercourses or navigable streams, which lands are
        included in surveys heretofore made, and to which lands patents or awards have
        been issued and outstanding for a period of ten years from the date thereof and have
        not been cancelled or forfeited, and the State of Texas hereby relinquishes, quit-
        claims and grants to patentees and awardees and their assignees all of the beds, and
        minerals therein contained, of water courses or navigable streams . . . ; provided
        that nothing in this Act contained shall impair the rights of the general public and
        the State in the waters of streams or the rights of riparian and appropriation owners
        in the waters of such streams . . . ; nor shall relinquish or quit-claim any number of
        acres of land in excess of the number of acres of land conveyed to said patentee or
        awardees in the original patents granted by the State . . . ; provided that this Act
        shall not in any way affect the State’s title, right or interests in and to the sand and
        gravel, lying within the bed of any navigable stream within this State, as defined by
        Article 5302, Revised Statutes of 1925 [the Navigable Stream Statute].

TEX. REV. CIV. STAT. art. 5414a(1)–(2). The Bill was enacted in 1929 “[t]o cure, as far as possible,

the defect in the claim of the owners whose patents and locations and awards cross navigable


                                                  15
streams” in violation of the Navigable Stream Statute. Bradford, 50 S.W.2d at 1071. To carry out

this purpose, the Small Bill expressly adopts the Navigable Stream Statute’s definition of

“navigable stream”—a definition that, as we have said, includes streams both above and below the

tide line. TEX. REV. CIV. STAT. art. 5414a(2) (“[N]avigable stream . . . as defined by Article 5302

[the Navigable Stream Statute] . . . .”).

        Beyond incorporating the Navigable Stream Statute’s definition, the Small Bill’s use of

comprehensive language further indicates the Legislature’s intent to validate surveys crossing both

tidal and nontidal portions of navigable streams. The Bill validates “[a]ll patents to and awards

of land lying across or partly across water courses or navigable streams and all patents and awards

covering or including the beds or abandoned beds of water courses or navigable streams or parts

thereof.” Id. art. 5414a(1) (emphases added). It also provides that the State “relinquishes, quit-

claims[,] and grants . . . all of the lands” and beds included in the relevant surveys. Id. art. 5414a(2)

(emphasis added).

        The Small Bill’s use of “all” matters. With the Small Bill, the Legislature implemented

“the public policy of this State to deal fairly with those who have purchased its public lands and

for some reason have not received the correct acreage so purchased and conveyed.” Bradford, 50

S.W.2d at 1071. Nothing in the Small Bill indicates the Legislature intended to deal less fairly

with those to whom the State had sold parts of the beds of navigable streams lying below the tide

line. The Small Bill never references the tide, never carves out tidally influenced areas, and never

shows a preference for beds of navigable streams located above the tide. We see no reason to

introduce a tidal distinction where the Legislature made none.




                                                   16
       For these reasons, the plain meaning of the term “navigable stream” that the Legislature

chose in the Small Bill is identical to its meaning under the Navigable Stream Statute, which

includes portions of streams below as well as above the tide line. By its express terms, therefore,

the Small Bill validates patents including the beds of those streams.

       C.      The common law’s adoption in 1840 does not change our conclusion.

       The Commissioner and our dissenting colleagues rely primarily on our State’s 1840

adoption of the common law to argue that the Navigable Stream Statute and Small Bill govern

only portions of navigable streams above the tide. They contend that tidal and non-tidal portions

of streams are governed by different systems of jurisprudence: the Navigable Stream Statute and

Small Bill apply to portions above the tide line, while the English common law governs portions

below the tide. Specifically, the Commissioner contends that tidally influenced portions of rivers

or streams are treated as tidewater and thus cannot be “navigable streams.” The dissent similarly

argues the common law renders below-tide portions of streams state-owned, so the Navigable

Stream Statute’s protections are unnecessary. Post at __ (Green, J., dissenting). Both cite the

common-law rule that tidally influenced waters are considered an “arm of the sea” owned by the

sovereign and governed by different rules than non-tidal waters. Post at __.

       Although these are correct statements of the common law, they do not impact our

interpretation of the statutory term “navigable stream” in this case. We agree with our dissenting

colleagues that there are key differences in the legal rules governing ownership of submerged land

above and below the tide line. All agree on how those rules apply here: the State owns the beds

of navigable streams on both sides of the line, and it can convey those beds to private owners if it

follows the proper steps to do so.



                                                17
       As we have explained, the civil law defined navigable streams and other rivers as extending

both above and below the tide line without distinction, and the state owned the beds of navigable

streams on both sides of the line. HALL’S MEXICAN LAWS §§ 1388, 1406. As the Commissioner

and dissent rightly explain, the common law subscribed to different rules, treating ownership of

streambeds above and below the tide line differently. When Texas adopted the common law in

1840, we did so insofar as “not inconsistent with the Constitution or the acts of Congress then in

force.” Motl, 286 S.W. at 465; see also Act approved Jan. 20, 1840, § 1. The Commissioner and

dissent fail to recognize that the common law’s adoption did not alter the meaning of navigable

stream or the state-owned status of the stream’s bed either above or below the tide.

       Above the tide line, the common law was not adopted because it was inconsistent with the

existing law in Texas at the time. See Motl, 286 S.W. at 465. Under the civil law as modified by

the Navigable Stream Statute, the beds of perennial streams and of streams with an average width

of thirty feet were state-owned and protected against certain types of sales. Manry, 56 S.W.2d at

446. But under the common law, the beds of streams above the tide were owned by riparian

landowners. Id. at 445. We have recognized that Texas “ignored [the common law’s] rule that

grants on streams above tidewater carry title to the thread of the stream” because the civil law, as

modified by the Navigable Stream Statute, is better suited to our conditions. Id. at 447.

       Below the tide line, adopting the common-law rule governing streambed ownership

changed nothing, as the common and civil laws on the subject were the same. See id. (perennial

streambeds below tide state-owned under civil law); JOSEPH ANGELL, TREATISE ON THE LAW OF

WATERCOURSES 729–32, §§ 542–45 (6th ed. 1854) [hereinafter LAW                OF   WATERCOURSES]

(streambeds below tide state-owned under common law).            The common law provided that



                                                18
“navigable streams” were state-owned and protected from sale, but such streams existed only

“within tidewater limits”—i.e., below the tide line.                Manry, 56 S.W.2d at 446; LAW               OF

WATERCOURSES 729–32, §§ 542–45; TREATISE ON TIDE WATERS 75–76. The dissent has argued

we must “harmonize” the civil- and common-law systems by holding that only common-law rules

apply below the tide. Post at __. But there is nothing to harmonize when the rules are the same. 10

        For these reasons, the disputed issue is not what rules apply to determine ownership of the

soil underlying navigable streams. Cf. post at __. Rather, the parties dispute what the term

“navigable stream” means, and thus what land was included when the Small Bill validated

conveyances of the state-owned beds of such streams. Parts III.A. and B. explain why that term

includes below-tide portions of streams under the civil law and the Navigable Stream Statute, and

therefore under the Small Bill as well.

        Contrary to the dissent’s position, the adoption of the common law did not change this

meaning. Cf. post at __. Indeed, by incorporating the Navigable Stream Statute’s definition of

navigable stream into the Small Bill, the Legislature carried forward a definition that must be

interpreted in light of the civil law. See Sabriego v. White, 30 Tex. 576, 587 (1868) (holding courts

cannot use common law to interpret statute passed before 1840). As we explained in Manry v.

Robison, “[t]he [Navigable Stream Statute] was not specifically amended by the act of 1840

[adopting the common law], nor by any subsequent law, and, in the absence of some specific




        10
           To the extent the dissent suggests the Navigable Stream Statute never applied to below-tide portions of
navigable streams because the common law covered them, we note that the common law was not in effect at the
Navigable Stream Statute’s enactment and thus has no bearing on the Statute’s original scope.



                                                       19
amendment we should give it the meaning which it had at the time of its enactment”—that is, a

civil-law meaning. 56 S.W.2d at 447. 11

         Nor did the common law’s adoption replace the Navigable Stream Statute below the tide.

Cf. post at __. The Navigable Stream Statute protects state-owned land in a manner unique and

inconsistent from the common law: it prohibits survey lines from crossing navigable streams. See

Act approved Jan. 20, 1840, § 1 (common law not adopted where inconsistent with current law).

         In any event, our conclusion that the meaning of the term navigable stream includes

portions of the stream below the tide line is entirely consistent with the common law’s conception

of navigable streams, which as noted existed only within tidewater limits. Thus, even if the

common law altered the Small Bill’s definition of “navigable stream,” we do not see how this

would support the dissent. Under that definition, the Small Bill would validate only surveys

crossing tidewater sections of streams: the opposite result from that reached by the dissent, post at

__, and one calling into question every above-tide streambed conveyance.

         The Commissioner and dissent emphasize that several opinions discussing navigable

streams limit their application to streambeds above the tide; thus, they posit, the Navigable Stream

Statute and Small Bill must not apply below the tide. Post at __. We cannot agree. Although the

common and civil laws differed markedly in their treatment of navigable stream beds above the




         11
            The dissent complains that our interpretation renders the common law meaningless. Post at __. This
complaint flies in the face of the 1840 act, which expressly provides that the common law applies only to the extent it
is not inconsistent with the acts in place at that time, which include the Navigable Stream Statute. The common law
can also be modified by subsequent statutes, such as the Small Bill’s re-enactment of the Navigable Stream Statute’s
definition. See Dugger v. Arredondo, 408 S.W.3d 825, 829 (Tex. 2013).



                                                         20
tide, the rules below the tide line were the same. Naturally, differences between the rules above

the tide have been litigated more frequently. 12

        In particular, the dissent contends Manry requires application of the common law to

navigable streams below the tide because the common law recognized that different rules apply

above and below the line. Post at __. The dissent makes too much of this portion of Manry,

however. In Manry, we refused to adopt a particular common-law rule applicable “only within

tidewater limits” in deciding whether abandoned riverbeds above the tide line passed to riparian

owners or the State. Manry, 56 S.W.2d at 448. The reason we gave is the one just discussed: the

civil law in force in 1840, as modified by the Navigable Stream Statute, is inconsistent with the

common law above the tide. Id. at 446. But that reason says nothing about whether the civil-law

and statutory definition of navigable stream is inconsistent with the common-law definition below

the tide. Because the authorities just discussed show the definitions are the same, there is no

conflict to resolve.

        D.       The Small Bill is a valid conveyance of public-trust submerged land both above
                 and below the tide line.

        The Commissioner and the dissent also argue that the Small Bill does not overcome the

public trust doctrine with respect to submerged streambeds below the tide line. It has long been

the law in Texas that navigable waters and their beds—both above and below the tide—are

“reserved to the State for the use of the public generally.” Lorino v. Crawford Packing Co., 175




        12
            See Luttes, 324 S.W.2d at 192 (civil-law tide line applies to civil-law grants and common-law tide line
applies to common-law grants);.Manry, 56 S.W.2d at 449 (abandoned riverbeds); Motl, 286 S.W. at 468 (public rights
of navigation over floodwaters).



                                                        21
S.W.2d 410, 414 (Tex. 1943) (below tide); Bradford, 50 S.W.2d at 1075 (above tide). 13 Private

parties may not have the exclusive right to the enjoyment of streambeds “unless and until the

Legislature has granted such right.” Lorino, 175 S.W.2d at 414. We presume “that there has not

been any act of the State divesting itself of title,” id., and we construe grants purporting to convey

these lands “strictly . . . against the grantee,” Bradford, 50 S.W.2d at 1075. To convey public-

trust lands, the Legislature must use “plain and positive language”:

         In view of the importance of this matter to the state and the whole people, the courts
         of this state have consistently held that all grants with respect to lands under
         navigable waters, such as river beds and channels, are strictly construed against the
         grantee; that, if there is any ambiguity in the act, it will be construed in favor of the
         state; and, unless the act contains plain and unmistakable language expressly
         conveying the land under river beds and channels, it will not be construed to include
         them. In other words, before a statute will be construed to include land under
         navigable waters, such as river beds and channels, it will have to be expressed in
         plain and positive language and not in general language.

Bradford, 50 S.W.2d at 1075. 14

         The Commissioner and the dissent recognize that the Small Bill expressly “grants . . . the

beds . . . of water courses or navigable streams,” and they concede this grant is valid as to

streambeds above the tide. TEX. REV. CIV. STAT. art. 5414a(2); see post at __. Yet they contend

the Small Bill does not contain the requisite “plain and positive language” to convey the beds of

streams below the tide, even though the language just quoted makes no tidal distinction. Post

at __. They advance several arguments in an effort to support this position, including the

Commissioner’s contention that the public trust doctrine applies with “heightened standards” to



         See also In re Adjudication of Water Rights of Upper Guadalupe Segment of Guadalupe River Basin, 642
         13

S.W.2d 438, 444 (Tex. 1982) (“Texas holds the title to the waters in a navigable stream in trust for the public.”).
         14
            As these authorities show, the dissent is incorrect that only portions of navigable stream beds below the
tide require express legislative relinquishment of state ownership. Post at __.



                                                         22
below-tide streambeds and the inconsistent language Texas law has used to describe navigable

waters. We are not persuaded.

       As just explained, the public trust doctrine applies equally to navigable stream beds above

and below the tide line, 15 as does the term navigable stream. Thus, if the Small Bill satisfies the

public trust doctrine as to conveyances including above-tide navigable stream beds, as the

Commissioner and dissent admit it does, the same must be true of its effect below the tide.

       In Bradford, we upheld the Small Bill against numerous constitutional challenges and held

it was a permissible statute enacted to “confirm and validate titles to land whose survey lines

cross[ed] the bed” of a navigable stream. Bradford, 50 S.W.2d at 1077. In doing so, we necessarily

concluded the Small Bill satisfied the public trust doctrine. See id. at 1075–76, 1079. But we

never relied upon the presence or absence of the tide in the navigable stream at issue, nor did we

exclude navigable streams below the tide from our holding.                Instead, we relied upon the

Legislature’s intent in enacting the Small Bill: to make existing patentees and awardees whole. Id.

at 1075–76.

       [T]he Small Bill did not undertake to give to the patentees and awardees and their
       assignees anything belonging to the state. The state issued the patents and awards;
       the state received the purchase price for the lands patented and awarded; the state
       still retains the consideration paid therefor; and, in the exercise of its power, the
       Legislature decided to retain the consideration received for the land and confirm to
       the landowners that which they had already bought and paid for or for which the
       state held their outstanding obligations.




       15
            See Lorino, 175 S.W.2d at 414; Bradford, 50 S.W.2d at 1075.



                                                       23
Id. 16 “That the state has authority to validate the titles of the land lying in the beds of navigable

streams issued in good faith . . . rests upon many precedents and sound authorities . . . .” Id. at

1077. Neither these statements nor anything else in Bradford indicates the Legislature chose to

retain the consideration paid by all patentees and awardees with surveys violating the Navigable

Stream Statute while validating only some of those surveys. If the Small Bill is a sufficiently plain

and positive conveyance of public-trust beds of navigable streams above the tide, it is a valid

conveyance of such beds below the tide as well.

         Accepting the dissent’s conclusion that the Small Bill is not a valid conveyance would

require overruling Bradford, which we decline to do. We recently noted that in cases involving

statutory construction, “stare decisis has its ‘greatest force.’” Worsdale v. City of Killeen, 578

S.W.3d 57, 68–69 (Tex. 2019). We see no reason to disturb Bradford—something even the

Commissioner has not asked us to do.

         The Commissioner and the dissent next argue that the Small Bill’s reference to beds of

“navigable streams” and “watercourses” is not a plain and positive conveyance of submerged land

below the tide line in light of the inconsistent language Texas authorities have used to distinguish

between tidal and non-tidal waters.              The Commissioner and dissent further contend that a

conveyance of the bed of a “navigable stream” is too imprecise and that a below-tide conveyance

must use more particular language. Post at __. The Commissioner notes that the Navigable Stream

Statute does not define “water course”—a term it uses interchangeably with “stream.” “Water

course,” the Commissioner argues, “referred to inland streams that were not tidally influenced” in


         16
            See also Bradford, 50 S.W.2d at 1077 (“The state having sold and conveyed the lands for a certain
consideration, and received and retained the consideration paid therefor, saw fit to retain the money paid or to be paid
and validate the titles to the land for which patents and awards have issued.”).



                                                          24
the 1830s. In support of this proposition, the Commissioner notes that two treatises by the same

author handle “water courses” and “tide waters” separately. But both treatises acknowledge that

the “navigable stream” concept blurs tidal and non-tidal lines. See LAW OF WATERCOURSES 738,

§ 550; TREATISE ON TIDE WATERS 79. They discuss the purely tidal nature of navigable streams

under the common law, and they discuss the civil law’s use of the term to include areas above and

below the tide. LAW OF WATERCOURSES 738, § 550; TREATISE ON TIDE WATERS 79. We find the

Commissioner’s argument regarding water courses unclear at best.

       For its part, the dissent contends that “navigable water”—not navigable stream—is the

term Texas uses to denote tidally influenced waters, and the Small Bill’s failure to use that term

means that it does not apply below the tide. Post at __. But the very cases the dissent cites refute

this position. In Bradford, we stated that navigable waters include navigable streams. Bradford,

50 S.W.2d at 1069 (“[T]he state is the owner of the soil underlying the navigable waters, such as

navigable streams, as defined by statute . . . .”); cf. post at __. Likewise, Manry and Seabrook

Land Co. v. Lipscomb refer to “tidewater sections of navigable streams.” Manry, 56 S.W.2d at

446; Seabrook Land Co. v. Lipscomb, 331 S.W.2d 429, 433 (Tex. App.—Houston 1960, writ

dism’d by agr.); cf. post at __.

       The Commissioner and the dissent next claim that our holding disturbs the rules of

streambed ownership in Texas, but we are simply holding that the Small Bill—a proper legislative

conveyance of submerged streambeds patented one hundred years ago—validates title to all of the

land the patentees paid for. See Bradford, 50 S.W.2d at 1071. Moreover, adopting the dissent’s

view would cause the true disruption. As we have explained, the dissent’s view would undermine




                                                25
the Small Bill’s validation of patents to streambeds above the tide. What is more, it would call

into question the City of Houston’s ownership of the Houston Ship Channel.

         The Houston Ship Channel, a substantial portion of which is below the tide, was conveyed

by the Legislature using language similar to that in the Small Bill. See TEX. REV. CIV. STAT. art.

7467a (1925) (conveying beds and abandoned beds of certain “rivers, streams[,] and other

channels”). If the Small Bill’s reference to navigable stream beds is insufficiently specific to

convey beds below the tide, as the dissent contends, the Ship Channel conveyance is even more

suspect. 17 The dissent counters that the Ship Channel conveyance was sufficiently specific

because it applied only to streambeds within the corporate limits of eight cities. Post at __. But

that statement is simply not responsive to the dissent’s own concern: narrowing the scope of the

conveyance to streambeds within certain cities has nothing to do with whether a conveyance of

those streambeds is sufficiently specific to include portions of the beds below the tide.

         Finally, the Commissioner points out that a motive for the Small Bill was to cure unrest in

arid and semi-arid areas of the State in response to our Motl decision. In those areas, the banks of

navigable streams are frequently wider than the water they contain, and claims were made after

Motl that patents including land between these banks violated the Navigable Stream Statute. But

the Commissioner’s view that the Small Bill applies only in those upland areas of Texas runs afoul

of the Bill’s plain language and ignores parts of our Motl decision. Although Motl did render




         17
           The dissent also argues that Justice Reavley’s personal footnote in Coastal Industrial Water Authority v.
York, a case considering the Houston Ship Channel, requires that we apply the common law below the line of mean
high tide. Post at __. But read carefully, that footnote addresses his desire that the case not affect the “boundary of
private ownership to lands within reach of the tide.” York, 532 S.W.2d at 952 n.1. In other words, it concerned
ownership disputes arising from the changing of the tide line over time. Id.



                                                         26
thousands of acres of land in drier areas of Texas susceptible to title disputes, 18 Motl did not limit

its holding to above-tide navigable streams. Motl construed the statutory definition of navigable

stream generally, repeatedly mentioning watercourses in other regions of Texas—including near

the Gulf—without excluding them from its reach. Indeed, this Court has applied Motl’s definition

to a grant affecting the Mission River, a river that “empties into a bay, which is an arm of the gulf”

just ten miles from the grant at issue there. Heard, 103 S.W.2d at 729–30. Thus, nothing in Motl

changes our conclusion that the Small Bill, by its plain language, applies to all parts of navigable

streams.

        E.       Our holding that the Small Bill conveys the beds of “navigable streams” below
                 as well as above the tide will have limited impact.

        The Commissioner warns that dire consequences will follow our holding that the Small

Bill conveys submerged beds of navigable streams. But as the Club explains, a holding that the

Small Bill encompasses portions of navigable streams below the tide line will affect very few

properties because the Small Bill carefully defines its parameters.

        The Small Bill validates and confirms grants meeting four requirements: (1) patents and

awards (2) granted at least ten years before the Small Bill’s 1929 enactment (3) lying across or

partially across (4) watercourses or navigable streams—terms encompassing water features that

meet certain criteria defined by Texas law. TEX. REV. CIV. STAT. art. 5414a; see Hoefs v. Short,

273 S.W. 785, 787 (Tex. 1925) (defining watercourse); Act approved Dec. 14, 1837, § 42 (defining

navigable stream). The Commissioner expresses particular concern about interpreting the Small

Bill to reach land underlying the Gulf of Mexico, but he has presented no evidence that any survey


       18
          See Hawkins, supra, at 501–02, 513–14 (noting that stream beds in the arid portions of Texas are often of
“enormous width” and are therefore navigable streams under Motl even if their flowing waters are quite narrow).



                                                        27
lines cross the Gulf. Even if some did, the Gulf is not a watercourse, nor is it a navigable stream.

Thus, those surveys would not be saved by the Small Bill. See TEX. REV. CIV. STAT. art. 5414a.

In addition, the Small Bill quitclaims only the number of acres of land necessary for the patentee

to be made whole. Finally, our holding does not affect the State’s ownership of land below mean

high tide and outside the gradient boundary of a watercourse or navigable stream because those

areas are not included within the Small Bill’s scope.

IV.    We remand for a determination of whether the bayou is a “navigable stream” or
       “watercourse.”

       In light of our conclusion that the Small Bill encompasses the beds of navigable streams

above and below the tide, we next consider whether the Club was entitled to summary judgment

that Lone Oak Bayou is a “navigable stream” or “watercourse” within the Bill’s scope.

       The Commissioner argues that the Club has failed to prove the Lone Oak Bayou is a

navigable stream or watercourse as a matter of law; thus, the court of appeals erred in affirming

summary judgment in the Club’s favor. In response, the Club argues the Commissioner waived

this argument, as he did not assert it in the courts below. Alternatively, the Club argues it has

established the bayou is a navigable stream or watercourse as a matter of law. We agree with the

Commissioner.

       As a preliminary matter, we disagree with the Club’s position that the Commissioner

waived this issue by failing to raise it in the court of appeals. In the trial court, the parties filed

cross-motions for summary judgment; thus, “each party [had] the burden of establishing that it

[was] entitled to judgment as a matter of law.” Tarr v. Timberwood Park Owners Ass’n, 556

S.W.3d 274, 278 (Tex. 2018). Because the Club asked the court to apply the Small Bill, the Club

had the burden to prove it applied as a matter of law. Bombardier Aerospace Corp. v. SPEP


                                                  28
Aircraft Holdings, LLC, 572 S.W.3d 213, 221 (Tex. 2019). As the non-movant, the Commissioner

was not required to produce evidence negating the Small Bill’s application. Amedisys, Inc. v.

Kingwood Home Health Care, LLC, 437 S.W.3d 507, 511 (Tex. 2014) (explaining that movant’s

summary judgment motion “must stand or fall on [its] own merits, and the non-movant’s failure”

to produce contrary evidence does not affect the movant’s right to summary judgment). Thus, the

Commissioner did not waive this issue.

         Turning to the merits, we conclude that summary judgment in favor of the Club was

improper because the Club failed to establish as a matter of law that all of Lone Oak Bayou within

the Barrow Survey is a navigable stream or watercourse. “A water course, river, or stream consists

of a bed, banks, and a stream of water.” Motl, 286 S.W. at 467; see also Hoefs, 273 S.W. at 786–

87 (“[A] stream in order to be a natural water course to which water rights attach must have bed,

banks, a current of water, and a permanent source of water supply . . . .”). To be a statutory

“navigable stream,” the average width between the banks must be 30 feet, and the stream continues

“so far up as [it] retain[s] that average width.” Motl, 286 S.W. at 466 (quoting 1 SAYLES’ EARLY

LAWS OF TEXAS 266, 271). We measure the distance between a stream’s banks considering the

“entire bed of the stream”: the land between the horizontal “gradient boundary” on each bank. Id.

at 467; Brainard v. State, 12 S.W.3d 6, 15–18 (Tex. 1999) (discussing gradient boundary surveys

in detail), disapproved of on other grounds by Martin v. Amerman, 133 S.W.3d 262, 267–68 (Tex.

2004).

         We have explained that a stream’s gradient boundary is “located midway between the

lower level of the flowing water that just reaches the cut bank, and the higher level of it that just

does not overtop the cut bank.” Diversion Lake Club v. Heath, 86 S.W.2d 441, 447 (Tex. 1935)



                                                 29
(quoting Oklahoma v. Texas, 265 U.S. 500, 501 (1924)). In other words, it is “that portion of [a

stream’s] soil which is alternately covered and left bare as there may be an increase or diminution

in the supply of water, and which is adequate to contain it at its average and mean stage during an

entire year.” Motl, 286 S.W. at 467.

       To constitute a “stream” or “water course” and calculate its gradient boundary, Lone Oak

Bayou must have banks. Id.; Brainard, 12 S.W.3d at 15–19; Diversion Lake Club, 86 S.W.2d at

447. The Club has not proven this to be the case. The Club’s evidence concerning the presence

of banks includes a surveyor affidavit stating that “[i]n certain areas Lone Oak Bayou has a

defined bank.” But the bayou has also “been described as a marsh, for which no banks exist,” and

for which “a gradient boundary cannot be determined.”

       Given this evidence, we cannot say conclusively that the bayou has defined banks, nor can

we determine their locations along the bayou’s waters. Thus, we hold the Club was not entitled to

summary judgment that the Small Bill validated the bayou bed’s conveyance. A “stream” or

“water course” bears that name only insofar as its bed, banks, and stream of water remain. Motl,

286 S.W. at 467. On this record, it is possible that some or all of the bayou’s waters within the

Barrow Survey do not constitute a stream or water course. We therefore remand to the trial court,

leaving open the question whether (and, if so, to what extent) the bayou within the Club’s tract is

a navigable stream or water course such that its conveyance was validated by the Small Bill.




                                                30
                                         *      *       *

       For these reasons, we hold a fact issue exists regarding whether this patent to a portion of

Lone Oak Bayou comes within the Small Bill’s scope of validation. We reverse the summary

judgment in favor of the Club and remand the cause to the trial court for further proceedings.
