¶ 1 Arizоna law allows landowners, outside of Active Management Areas, to make reasonable and beneficial use of groundwater underlying their land. This case involves deeds that purported to reserve to the grant- or, and to sever from the surface estate, rights to the potential future use of groundwater. Because a landowner has no real property interest in the future use of groundwater, we hold that the attempted reservation is invalid.
FACTS AND PROCEDURAL HISTORY
¶ 2 This case concerns land in the Chino Valley in Yavapai County that is commonly referred to as the CF Ranch. In 1981, Red Deer Cattle, Inc. (“Red Deer”) bought this land from Chino Ranch, Inc. (“Chino Ranch”). In its 1981 deed to Red Deer, Chino Ranch reserved all mineral rights and “сommercial water rights” but did not otherwise retain any ownership interest in the land. In 1984, Red Deer conveyed the CF Ranch to Merwyn C. Davis, acting as a trustee for a trust bearing his name. Similar to the 1981 deed, this deed purported to reserve to the grantor “all commercial water rights and waters incident and appurtenant to and within the real property,” but рrovided that Davis could use water for “ranch, livestock and domestic and agriculturally related purposes.”
¶ 3 Chino Ranch merged with Red Deer in 1989, thereby consolidating their respective claims to the commercial water rights associated with the CF Ranch. Following a series of conveyances involving third parties, in May 1998, Red Deer and CJ Partners each conveyed a one-half interest in the commercial water rights for the CF Ranch to Agua Sierra Resources L.L.C. (“Agua Sierra”).
¶ 4 In April 2003, Davis granted the City of Prescott an option to purchase the CF Ranch and the adjacent CV Ranch, as well as the water rights appurtenant to the two properties, for $30 million. The option agreement included an addendum stating that Davis was uncertain about the water rights on the properties and that his interest “in said water rights may be unclear, incomplete, inappropriately described, or subject to challenge.” At the time of the option contract, the properties appraised at $23 million, of which $18 to $21 million was attributable to the associated water rights. Accordingly, the City asked Davis to purchase the water rights so that the City could acquire them. Because Davis was unable to purchase the water rights from Agua Sierra, the City allowed the option to expire.
¶ 5 Four months later, Davis filed a complaint against Agua Sierra, Red Deer, CJ Partners, and the Seibert Family Limited Partnership (collectively, the “Agua Sierra
¶ 6 On cross-motions for summary judgment, the trial court held the reservation invalid and entered judgment for Davis. In doing so, the trial court relied on opinions of this Court stating that “there is no right of ownership of groundwater in Arizona prior to its сapture and withdrawal,”

I”),
¶ 7 The court of apрeals vacated the trial court’s judgment, holding that Arizona law allows a grantor to reserve rights to the prospective commercial use of percolating groundwater beneath the land conveyed.
Davis v. Agua Sierra Res., L.L.C.,
¶ 8 We accepted review because this ease presents an issue of first impression and statewide importance. Our jurisdiction is based on Article 6, Section 5(3) of the Arizona Constitution and Arizona Revised Statutes (“A.R.S.”) section 12-120.24 (2003).
DISCUSSION
A. Arizona Groundwater Law
¶ 9 The 1981 and 1984 deeds for the CF Ranch purport to reserve to the grantor, and thus to sever from the surface estate, all “commereial water rights.” The parties agree that there has not been any historical use of such water rights on the CF Ranch and that there is no issue before the Court regarding approрriable waters. This case instead involves the potential future use of groundwater that has never been captured and put to reasonable use.
¶ 10 Arizona law distinguishes groundwater from surface water, even though such waters may be hydrologically connected. John D. Leshy & James Belanger, Arizona Law Where Ground and Surface Water Meet, 20 Ariz. St. L.J. 657, 659 (1988). Surface water is subject to the doctrine of prior appropriation.
In re the Gen. Adjudication of All Rights to Use Water in the Gila River Sys. & Source (“Gila River IV”),
¶ 11 Because others have detailed the history of Arizona groundwater law,
see Cherry v. Steiner,
¶ 13 The GMA divided the state into three categories: Active Management Areas (“AMAs”),
id.
§ 45-411, Irrigation Non-Expansion Areas (“INAs”),
id.
§ 45-431, and areas outside a designated AMA,
id.
§ 45-453. AMAs are “geographical areas where groundwater supplies are imperiled.”
Chino Valley II,
¶ 14 The CF Ranch, located within the Big Chino sub-basin, is not within аn AMA and thus is not subject to the extraction and use limits applicable to AMAs. The GMA, however, does govern the withdrawal of groundwater on land outside an AMA if the water is to be transported to an established AMA. Id. § 45-551.
¶ 15 The Prescott Active Management Area includes the City of Prescott. Id. § 45-411(A)(3). The GMA thus regulates any withdrawal and transportation of groundwater from the CP Ranсh to the City of Prescott. In general, the GMA provides that “[i]n areas outside of active management areas, a person may: 1. Withdraw and use groundwater for reasonable and beneficial use, except as provided in article 8.1 of this chapter. 2. Transport groundwater pursuant to articles 8 and 8.1 of this chapter.” Id. § 45-453. Article 8.1 further providеs that in the case of the Big Chino sub-basin,
[a] city or town that owns land consisting of historically irrigated acres in the Big Chino sub-basin of the Verde River groundwater basin, as designated by order of the director dated June 21, 1984, or a city or town with the consent of the landowner, may withdraw from the land for transportation to an adjacent initial active management area an amount of groundwater determined pursuant to this section.
Id. § 45-555(A). The GMA limits the annual transportation allotment based on the historically irrigated acres retired from irrigation. Id. § 45-555(B).
¶ 16 Although the Agua Sierra parties claim they own the “commercial water rights” reserved by the prior owners of the CP Ranch, the GMA does not recognize the existence of anything called a “commercial water right” to groundwater.
B. Future Rights to Groundwater
¶ 17 The court of appeals held that a grantor may reserve rights to the commercial use of percolating groundwater beneath land that the grantor no longer owns.
Davis,
¶ 18 Por a deed reservation of commercial groundwater rights to be valid, however, the grantor must in fact have a real property interest in such rights. Thus, we first consider whether Arizona law recognizes a real property right to the potential future use of groundwater.
¶ 19 This Court has noted that “Arizonа law recognized no right to reserve water for some potential future use.”
Gila River I,
¶ 20
Gila River I
concerned both real property owners who claimed rights to ap-propriable subflows and other land owners who claimed that their interests would be impacted by any legal determination of “when underground water is appropriable.”
¶ 21 The Court in
Gila River I
also cited its earlier decision
Chino Valley II,
which addressed groundwater rights under the GMA, not appropriable water rights.
Gila River I,
¶ 22
Chino Valley II
used the term “usu-fruct” to describe the rights of landowners with respect to underlying groundwater. But
Chino Valley II’s
use of that term does not mean that landowners have some vested real property right in the potential use of groundwater.
See Gila River IV,
¶ 23 Recognizing that Arizona’s groundwater is a critical public resource, the legislature has granted landowners outside оf AMAs a limited right, essentially an opportunity, to pump groundwater for reasonable and beneficial uses as permitted by the GMA.
See
A.R.S. §§ 45-453, -541 to -554;
see also
Leshy & Belanger,
supra,
at 715-16 (discussing GMA’s impact on reasonable use doctrine). The legislature is free to choose between competing uses of groundwater and to modify such rights in the public interest as an exercise of its police pоwer.
Chino Valley II,
¶ 24 Agua Sierra and its predecessors have not identified any pre-existing or current use of the groundwater underlying the CF Ranch that is embraced by the reservation of commercial water rights. Arizona law does not recognize a real property interest in the potential future use of groundwater that has never been captured and applied to reasonable use. 1
C. Severability of Right to Potential Use of Groundwater
¶ 25 The Agua Sierra parties also argue that the deed reservations were at least effective to sever and reserve to the grantor whatever “rights” a surface owner would oth
erwise
¶ 26 The court of appeals observed that “Arizona law generally permits the severance and transfer of water rights from the associated real property.”
Davis,
¶ 27 The cases cited by the court of appeals, however, do not establish a severable right to the potential future use of groundwater.
West Maricopa Combine
involved the transfer of Central Arizona Project water via the Hassayampa riverbed.
¶ 28
Paloma,
however, did not involve the severance of a right to the potential future use of groundwater. Instead,
Paloma
concеrned a water rights agreement giving one party a share of the proceeds from future sales of water from the land by the fee owner.
See
¶ 29 Nor did this Court in
Neal
decide whether the potential use of groundwater is a property right severable from the overlying land. In that ease, the grantor reserved certain water rights to a ranch he had sold.
¶ 30
Neal
preceded this Court’s decision in
Chino Valley II,
which rejected as dicta language in prior decisions, including
Howard,
suggesting that a landowner may have a property interest in groundwater.
See Chino Valley II,
¶ 31 On the issue of severability, more pertinent is the. language of the GMA itself, which provides that the landowner must consent to the transportation of water off the property:
A city or town that owns land consisting of historically irrigated acres in the Big Chino sub-basin of the Verde River groundwater basin ... or a city or town with the consent of the landowner, may withdraw from the land for transportation to an adjacent initial active management area an amount of groundwater determined pursuant to this section.
A.R.S. § 45-555(A)(emphasis added).
¶ 32 Section 45-555(A) presumes that a landowner has authority to consent to a city or town’s withdrawing water from the land for transportation. But a landowner would not be able to grant such consent if a prior
¶ 33 We recognize that there are many policy arguments for or against allowing the transfer, outside of AMAs, of rights to prospectively usе groundwater, but those arguments should be weighed by the legislature if it thinks it desirable to amend this aspect of the GMA.
See Chino Valley II,
CONCLUSION
¶ 34 For the reasons stated, we hold that landowners outside of AMAs do not have a real property interest in the potential future use of groundwater that may be severed from the overlying land. Accordingly, we vacate the opinion of the court of appeals and remand so that court may consider other properly preserved arguments by the Agua Sierra parties challenging the trial court’s judgment for Daws.
Notes
. We do not here address the circumstances in which the owner of the surface estate may, consistent with the GMA, grant others contractual rights to withdraw, use, or transport groundwater from beneath the owner’s land.
