OPINION
By the Court,
This appeal concerns whether state-owned land that was once submerged under a waterway can be freely transferred to respondent Clark County, or whether the public trust doctrine prohibits such a transfer. Generally, under the public trust doctrine, a state holds the banks and beds of navigable waterways in trust for the public and subject to restraints on alienability. Although the public trust doctrine has never expressly been adopted in Nevada, this court has previously applied some of its tenets and its existence is implicit in Nevada law.
Thus, in this opinion, we clarify Nevada’s public trust doctrine jurisprudence by expressly adopting the doctrine and determining its application in Nevada, given the public’s interest in Nevada’s waters and the law’s acknowledgment of that interest. In so doing, after setting forth the facts and procedural history, we will discuss the development of the public trust doctrine in general, and then its development in Nevada specifically. Next, we will set forth Nevada’s public trust doctrine framework, under which we con- *392 elude that whether the formerly submerged land is alienable, such that it can be transferred to Clark County, turns on the unanswered questions of whether the stretch of water that once covered the land was navigable at the time of Nevada’s statehood, whether the land became dry by reliction or by avulsion, and whether transferring the land contravenes the public trust. We thus reverse the district court judgment underlying this appeal, which determined that the disputed land is transferable to Clark County, and we remand this matter for determinations as to whether the disputed land was submerged beneath navigable waters at the time of Nevada’s statehood, how it became dry land, and, if necessary, whether its transfer accords with the public’s interest in it.
FACTS AND PROCEDURAL HISTORY
The Nevada Legislature originally enacted the Fort Mohave Valley Development Law (FMVDL) to allow the Colorado River Commission (CRC), an executive state agency, to acquire federal land in the Fort Mohave Valley near Laughlin, within Clark County limits. The FMVDL was recently amended to require the CRC to transfer its Fort Mohave Valley land to Clark County. To effectuate the transfer, the Nevada State Land Registrar, appellant James R. Lawrence, deeded to Clark County the CRC’s interest in the Fort Mohave Valley land, except for approximately 330 acres of land adjacent to the Colorado River that he believed was nontransferable under the public trust doctrine, pursuant to which the state must hold the beds and banks of navigable waterways in trust for the public.
In response, Clark County filed a complaint for declaratory relief in district court, seeking an order declaring that Lawrence was required by legislative mandate to transfer the land to Clark County. Lawrence answered the complaint and filed a counterclaim for declaratory relief, seeking a declaration that the disputed land was subject to the public trust doctrine and therefore was not transferable. Clark County filed its answer and a motion for judgment on the pleadings, arguing, among other things, that the Legislature had already determined that the transfer was in the public’s interest and that nothing in the federal or state constitutions prohibited the transfer.
Following a hearing on Clark County’s motion for judgment on the pleadings, during which the parties debated whether the public trust doctrine applies in Nevada and, if it does, whether the disputed land fell within its purview, the district court determined that the disputed land was not subject to the public trust doctrine because it was not within the current channel of the Colorado River. The district court, therefore, granted Clark County’s motion and ordered Lawrence to deed the disputed land to Clark County *393 within 30 days. Lawrence now appeals. The district court granted a stay of its judgment pending the resolution of this appeal.
DISCUSSION
I. Standard of review
Judgment on the pleadings is proper when, as determined from the pleadings, the material facts are not in dispute and the moving party is entitled to judgment as a matter of law.
Bonicamp v. Vazquez,
H. The public trust doctrine’s emergence and development
As noted, whether the disputed land is transferable turns on whether it is subject to the public trust doctrine and, if so, how that doctrine applies in Nevada. To answer those questions, we begin with a discussion of the public trust doctrine’s origins and development.
A. Origins
The public trust doctrine is an ancient principle thought to be traceable to Roman law and the works of Emperor Justinian.
See State
v.
Sorensen,
The doctrine was thereafter adopted by the common law courts of England, which espoused the similar principle that “title in the soil of the sea, or of arms of the sea, below ordinary high-water mark, is in the King” and that such title “is held subject to the public right.”
Shively
v.
Bowlby,
B. The development of the public trust doctrine in the United States
Courts in this country have readily embraced the public trust doctrine. In 1821, in the first notable American case to ex *394 press public trust principles, the Supreme Court of New Jersey observed that citizens have a common right to sovereign-controlled waterways:
The sovereign power itself . . . cannot, consistently with the principles of the law of nature and the constitution of a well ordered society, make a direct and absolute grant of the waters of the state, divesting all the citizens of their common right. It would be a grievance which never could be long borne by a free people.
Arnold v. Mundy,
Thereafter, the United States Supreme Court similarly recognized that “when the Revolution took place, the people of each state became themselves sovereign; and in that character hold the absolute right to all their navigable waters and the soils under them for their own common use.”
Martin et al. v. Waddell,
Fifty years later, in what has become the seminal public trust doctrine case, the Supreme Court decided
Illinois Central Railroad
v.
Illinois,
is not consistent with the exercise of that trust which requires the government of the State to preserve such waters for the use of the public. . . . The State can no more abdicate its trust over property in which the whole people are interested than it can abdicate its police powers in the administration of government and the preservation of the peace.
Id. at 453.
While the Court noted that such lands need not, under all circumstances, be perpetually held in trust, it recognized that in effecting transfers, the public interest is always paramount, provid *395 ing that “[t]he control of the State for the purposes of the trust can never be lost, except as to such parcels as are used in promoting the interests of the public therein, or can be disposed of without any substantial impairment of the public interest in the lands and waters remaining.” Id.
C. Nevada’s embrace of public trust doctrine principles
Although Nevada has never expressly adopted the public trust doctrine, our caselaw has adhered to several principles relevant to the existence of the public trust doctrine in this state. The following three cases illustrate that, while the doctrine was not formally adopted, this state has previously embraced the tenets on which it is based.
1. State Engineer v. Cowles Bros., Inc.
The first case in which we recognized concepts foundational to the public trust doctrine is a 1970 case,
State Engineer v. Cowles Bros., Inc.,
[w]hen a territory is endowed with statehood one of the many items its sovereignty includes is the grant from the federal government of all navigable bodies of water within the particular territory, whether they be rivers, lakes or streams. If the body of water is classified as non-navigable at the time of the creation of the state, the underlying land remains the property of the United States, but if it is navigable under the definition hereinafter stated, the water and the bed beneath it becomes the property of the state.
Id.
at 874,
2. State v. Bunkowski
We furthered the application of public trust doctrine principles with respect to state-owned navigable waterways two years later in
State v. Bunkowski,
It has been held, in what appears to be a majority of cases, that the states hold title to the beds of navigable watercourses in trust for the people of their respective states. Titles to navigable water beds are normally inalienable. In Alameda Conservation Association v. City of Alameda,70 Cal. Rptr. 264 (Cal. App. 1968), it was held that while the state owns land under bays, such lands can be transferred by the state free of trust upon proper legislative determination, citing People v. California Fish Co.,138 P. 79 (Cal. 1913).
Id.
at 634,
3. Mineral County v. State, Department of Conservation
The most recent case dealing with issues connected to the public trust doctrine,
Mineral County v. State, Department of Conservation, 111
Nev. 235,
This court has itself recognized that this public ownership of water is the “most fundamental tenet of Nevada water law.” Additionally, we have noted that those holding vested water rights do not own or acquire title to water, but merely enjoy a right to the beneficial use of the water. This right, however, is forever subject to the public trust, which at all times “forms the outer boundaries of permissible government action with respect to public trust resources.” In this manner, then, the public trust doctrine operates simultaneously with the system of prior appropriation.
Id.
(quoting
Desert Irrigation, Ltd. v. State of Nevada,
Justice Rose noted that every Nevada citizen has a vested interest in the water from Walker River and expects the state’s natural resources to be preserved.
Id.
at 248,
If the current law governing the water engineer does not clearly direct the engineer to continuously consider in the course of his work the public’s interest in Nevada’s natural water resources, then the law is deficient. It is then appropriate, if not our constitutional duty, to expressly reaffirm the engineer’s continuing responsibility as a public trustee to allocate and supervise water rights so that the appropriations do not “substantially impair the public interest in the lands and waters remaining.” “[T]he public trust is more than an affirmation of state power to use public property for public purposes. It is an affirmation of the duty of the state to protect the people’s common heritage of streams, lakes, marshlands and tidelands, surrendering that right of protection only in rare cases when the abandonment of that right is consistent with the purposes of the trust.” Our dwindling natural resources deserve no less.
Id.
at 248-49,
*398 III. The sources and functions of the public trust doctrine in Nevada
With the foregoing discussion in mind, we turn to the parties’ arguments regarding the public trust doctrine in this matter. Lawrence argues that this state has adopted the public trust doctrine and, consequently, that the disputed land is not transferable. But as Justice Rose recognized, although Nevada law embraces public trust doctrine principles, this court has never expressly adopted that doctrine. Further, as the caselaw noted above indicates and common sense dictates, the public trust doctrine does not always prohibit the transfer of trust land.
Clark County argues that we should not adopt the public trust doctrine to review the Legislature’s conveyances of trust property, because the public trust doctrine is rooted in common law and, thus, cannot supersede legislation.
See, e.g., Gwathmey
v.
State through Dept. of Envir.,
A. Sources of the Nevada public trust doctrine
As an initial matter, we note that the public trust doctrine is not simply a common law remnant. Indeed, in addition to the Nevada caselaw discussed above, public trust principles are contained in Nevada’s Constitution and statutes and are inherent from inseverable restraints on the state’s sovereign power.
*399 1. Public trust doctrine principles in the Nevada Constitution
Article 8, Section 9 of the Nevada Constitution prohibits the gift or loan of public funds and credit: ‘ ‘The State shall not donate or loan money, or its credit, subscribe to or be, interested in the Stock of any company, association, or corporation, except corporations formed for educational or charitable purposes.” Similar provisions in other state constitutions are referred to as gift clauses, as they generally prohibit gifts of taxpayer funds.
In considering Nevada’s gift clause, we have stated that transactions disbursing public funds must be struck down if not made for a public purpose.
State ex rel. Brennan
v. Bowman,
Thus, the Legislature’s ability to dispose of the public’s resources is expressly limited by the gift clause, at the core of which lays the principle that the state acts only as a fiduciary for the public when disposing of the public’s valuable property.
See Brennan,
2. Public trust doctrine principles in Nevada statutes
Another source of Nevada law that evinces the public trust doctrine is our statutory law, specifically, NRS 321.0005 and NRS 533.025.
NRS 321.0005 provides, in pertinent part:
The Legislature declares the policy of this State regarding the use of state lands to be that state lands must be used in the best interest of the residents of this State, and to that end the *400 lands may be used for recreational activities, the production of revenue and other public purposes.
(Emphasis added.) Thus, by its express language, NRS 321.0005 contemplates fiduciary-type duties with regard to the state’s administration of state lands.
NRS 533.025 provides that “[t]he water of all sources of water supply within the boundaries of the State whether above or beneath the surface of the ground, belongs to the public.” Notably, NRS 533.025 does not provide that Nevada’s water belongs to the state; rather, it belongs to the public. Thus, as Justice Rose proposed, NRS 533.025 provides grounding for the Nevada public trust doctrine.
See Mineral County v. State, Dep’t of Conserv., 117
Nev. 235, 247,
3. Public trust doctrine principles inherent from limitations on the state’s sovereign power
The final underpinning of our formal adoption of the public trust doctrine arises from the inherent limitations on the state’s sovereign power, as recognized in
Illinois Central Railroad v. Illinois,
In sum, although the public trust doctrine has roots in the common law, it is distinct from other common law principles because it is based on a policy reflected in the Nevada Constitution, Nevada statutes, and the inherent limitations on the state’s sovereign power, as recognized by
Illinois Central.
Accordingly, in the words of Justice Rose, it is “appropriate, if not our constitutional duty,” to expressly adopt the doctrine to ensure that the state does not breach its duties as a sovereign trustee, and we do so here.
Mineral County,
B. Determining whether land is public trust land
With regard to Clark County’s argument that adopting the public trust doctrine unwisely assigns to courts the difficult task of determining if, at any point, a given parcel of land was beneath a navigable body of water in order to determine its trust character, we disagree.
1. Establishing whether the land was submerged beneath navigable waters
As an initial matter, the public trust doctrine is rooted in our constitutional and statutory law and inherent limitations on the state’s power and, thus, cannot be relaxed simply because it may present courts with difficult factual questions. And in any event, Clark County overstates the complexity of determining the character of land for public trust doctrine purposes.
Determining whether land is held in trust for the public by the state begins by reference to whether the land was submerged beneath navigable water when Nevada joined the United States on October 31, 1864, as Nevada joined the United States on equal footing with other states in every respect,
State
v.
Bunkowski,
2. Establishing how the land became dry
If land was beneath navigable waters when Nevada joined the United States, but is now exposed, whether that land remains subject to the public trust doctrine generally depends on the manner in which it became dry — whether by reliction
2
or avulsion.
3
See Cowles,
When the exposure is due wholly or in part to artificial causes and those causes are not the act of the party owning the shoreland the rules that prevail as to the ownership of the accreted or relicted land are the same as in the case of accretion or reliction solely by natural causes.
Id.
In contrast, when changes to the water bed occur by avulsion, that is, by “sudden changes in the course of a stream,” title is not taken away or bestowed.
Peterson v. Morton,
In
Cowles,
we applied the doctrine of reliction in determining that the state had lost its title to once-submerged land that had gradually and imperceptibly become dry.
Here, whether the disputed land became dry through reliction or avulsion is critical. If it was through reliction, the public trust doctrine does not apply to that land. But if the portion of the Colorado River covering the land was navigable at the time of Nevada’s statehood, and the land thereafter became dry through avulsion, the public trust doctrine applies. And if the public trust doctrine applies, whether the disputed land is transferable turns on whether *404 the transfer serves the public’s interest in the land and comports with the state’s trustee obligations, as discussed next.
C. Determining whether public trust land is transferable
Resolution of disputes over title to public trust land is a matter of state law.
See Phillips Petroleum Co. v. Mississippi,
In
Arizona Center for Law v. Hassell,
The Arizona Center for Law in the Public Interest and several individuals (collectively, Arizona Center) commenced a lawsuit against Arizona Land Commissioner Milo J. Hassell, the state land department, and the State of Arizona (collectively, Land Commissioner). Id. at 163. Arizona Center sought to invalidate the legis *405 lation, alleging that it “violated the gift clause of the Arizona Constitution . . . and the state’s sovereign duty to protect the public [interest].” Id. (citations omitted). The trial court granted the Land Commissioner summary judgment, determining that “[e]ven if the rivers were navigable at statehood, ... the state could legally relinquish its claims to the riverbeds for the purpose of ‘un-clouding title.’ ” Id. Arizona Center appealed. Id.
Although the parties in Hassell briefed the gift clause and public trust issues separately, the Arizona Court of Appeals considered them in unison. Id. at 166. The court explained, “Because the gift clause of the Arizona Constitution explicitly limits governmental freedom to dispose of public resources, it provides an appropriate framework for judicial review of an attempt by the legislative and executive branches to divest the state of a portion of its public trust.” Id. Relying upon Arizona’s gift clause jurisprudence, the Hassell court then fashioned the following test for reviewing the validity of dispensations of trust property:
[W]hen a court reviews a dispensation of public trust property, . . . public purpose and fair consideration ] must be shown. . . .
[A]ny public trust dispensation must' also satisfy the state’s special obligation to maintain the trust for the use and enjoyment of present and future generations.
Id. at 170. Applying this test, the Hassell court concluded that the legislation being challenged was “invalid under the public trust doctrine and [the gift clause] of the Arizona Constitution.” Id. at 173.
Because we find the reasoning enunciated in
Hassell
persuasive and harmonious with our own gift clause and public trust jurisprudence, we adopt the
Hassell
approach to reviewing dispensations of public trust property. Accordingly, when assessing such dispensations, courts of this state must consider (1) whether the dispensation was made for a public purpose, (2) whether the state received fair consideration in exchange for the dispensation, and (3) whether the dispensation satisfies “the state’s special obligation to maintain the trust for the use and enjoyment of present and future generations.”
Id.
at 170. The first two considerations are common to any dispensation of public trust property,
see, e.g., State ex rel. Brennan v. Bowman,
“[T]he degree of effect of the project on public trust uses, navigation, fishing, recreation and commerce; the impact of the individual project on the public trust resource; the impact of the individual project when examined cumulatively with existing impediments to full use of the public trust resource . . . ; the impact of the project on the public trust resource when that resource is examined in light of the primary purpose for which the resource is suited, i.e. commerce, navigation, fishing or recreation; and the degree to which broad public uses are set aside in favor of more limited or private ones.”
Id.

Kootenai Environ. Alliance v. Panhandle Yacht,
CONCLUSION
We expressly adopt the public trust doctrine in Nevada. We decline, however, to consider in this appeal whether the amended portions of the FMVDL comport with the public trust doctrine, as that determination would be premature. 5 Specifically, whether the *407 land is transferable by the state to Clark County initially turns on whether it was submerged beneath a navigable stretch of the Colorado River at the time of Nevada’s statehood, and if it was, whether it became dry through reliction or avulsion. As the district court entered judgment on the pleadings, those material questions of fact remain unanswered. We therefore conclude that judgment on the pleadings was improper, and we reverse the district court’s judgment and remand this case to the district court with instructions to evaluate whether the disputed land was beneath a navigable waterway at the time of Nevada’s statehood and how it became dry. If, on remand, the district court finds that the disputed land was beneath navigable waters and became dry through avulsion, the district court must then determine whether the portions of the FMVDL conveying those lands to Clark County contravene the public trust.
Notes
Our remaining case in the public trust realm,
Pyramid Lake Paiute Tribe v. Washoe County,
Reliction is defined as “[a] process by which a river or stream shifts its location, causing the recession of water from its bank.” Black’s Law Dictionary 1404 (9th ed. 2009). A companion concept is accretion. However, reliction differs in that it “is applied to land made by the withdrawal of the waters by which it is covered,” 93 C.J.S. Waters § 177 (2001) (emphasis added), whereas accretion is “[t]he gradual accumulation of land by natural forces.” Black’s Law Dictionary 23 (9th ed. 2009) (emphasis added).
Avulsion, as it relates to waterways in the instant context, is “the sudden and rapid change of the channel of the stream which is the boundary, whereby it abandons its old and seeks a new bed.” 93 C.J.S. Waters § 183 (2001) (footnote omitted).
Article 9, Section 7 of the Arizona Constitution provides, in relevant part, that the state “shall [not] ever give or loan its credit in the aid of, or make any donation or grant, by subsidy or otherwise, to any individual, association, or corporation.” While we note that Arizona’s gift clause does not include a reference to money like Nevada’s gift clause, this textual difference does not have any practical significance as it pertains to the public trust doctrine because both clauses reflect a strong policy limiting the state’s ability to dispose of public resources.
The County argues that the amended FMVDL is not within the scope of the public trust doctrine because it does not directly convey the disputed land to a private entity. We cannot agree.
If we were to accept the County’s argument, the state could easily use a government subdivision as a conduit to circumvent its trustee duties. See 65 C.J.S. Navigable Waters § 131 (2010) (explaining that although the state may generally grant public trust land to municipalities, such transfers must be made for a purpose that is consistent with the public trust doctrine); Joseph L. Sax, The Public Trust Doctrine in Natural Resource Law: Effective Judicial Intervention, 68 Mich. L. Rev. 471, 490 (1970) (“When a state holds a resource which is available for the free use of the general public, a court will look with considerable skepticism upon any governmental conduct which is calculated either to reallocate that resource to more restricted uses or to subject public uses to the self-interest of private parties.”). We therefore conclude that legislation conveying public trust property from the state to a government subdivision is within the ambit of the public trust doctrine and must be analyzed to determine whether such a conveyance results in a violation of the public trust.
