delivered the Opinion of the Court.
¶1 This is an appeal by Barthelmess Ranch, Double 0 Ranch, William French, Conni French, Craig French and M Cross Cattle (the Objectors) from the Water Court’s August 11, 2015 Order Granting Partial Summary Judgment and Order Remanding to the Master. We affirm.
¶2 We restate the issues on appeal as follows:
Issue One: Whether the Water Court erred in concluding that the United States Bureau of Land Management (BLM) holds stockwatering rights under Montana law in reservoirs constructed on federal land for the use of permittees.
Issue Two: Whether the Water Court erred in concluding that the United States owns reserved water rights for stockwatering by permittees in a pothole lake on federal grazing land under the 1926 Executive Order providing for Public Water Reserve 107.
FACTUAL AND PROCEDURAL BACKGROUND
¶3 In Montana’s ongoing water rights claims adjudication proceedings, the BLM filed six water right claims related to five reservoirs and one natural pothole. The five reservoir claims are based in Montana law while the Pothole Lake claim is based upon a federal reservation of lands. The water sources are located wholly or partially on federal land, and the BLM claims the right to use each for stockwatering by its grazing permittees and for wildlife. In June 2014 the BLM moved for summary judgment on the objections raised to each claim. The Water Court consolidated those claims, objections and motions for summary judgment into the present single case.
¶4 In November 2014 the Water Master recommended summary judgment in favor of the BLM on each of these claims, finding that the claims were valid and properly owned by the BLM. The Objectors objected to the Water Master’s recommendation, but agreed in briefing that the BLM had the right to obtain water rights in its name under Montana law for use on federal lands.1 The Objectors stated the issue *123as whether the BLM “under applicable state and federal laws, actually made appropriations for beneficial use.” The Objectors contend that the BLM did not perfect any water rights and sought an order from the Water Court transferring all of the claimed BLM water rights to the current grazing permittee on the federal lands, and an order terminating all the wildlife claims. The Water Court upheld the Water Master’s recommendation in most respects, and the Objectors appeal.
¶5 The following is a summary of the BLM claims involved in the present case. Windy Day Reservoir (Claim 40M 74594-00) was built by the BLM in August 1955 with the participation and cost-sharing of Marie Karstens-Redding, the BLM grazing permittee at the time. The French objectors in the present appeal own property surrounding the Windy Day Reservoir. They claim that as early as 1911 individual “free grazers” who were ancestors or predecessors to their current land interests (hereafter “ancestral free grazers”) “owned livestock” on the land now containing this reservoir.
¶6 North Flat Creek Reservoir (Claim 40M 74590-00) was built by the BLM in 1937. It is partially located on lands patented by Elsie Kemp/Tole in 1923 and conveyed to the Frenches in 1995. Frenches filed a statement of claim to a use right for stockwater out of the reservoir. They claim that as early as 1911 ancestral free grazers placed livestock on the land now containing this reservoir.
¶7 Tallow Creek Reservoir (Claim 40M 74670-00) was built by the BLM in June 1936. The Objectors contend that ancestral free grazers in the area of this reservoir owned livestock there as early as 1915, and that their stock grazed in the area and drank water.
¶8 Sharon Reservoir (Claim 40M 74883-00) was built by the BLM in 1961 with the assistance of the Oxarart Brothers, grazing permittees at the time. M Cross is a grazing permit successor to Oxararts and has repair and maintenance responsibility for the reservoir. M Cross claims that its ancestral free grazers “owned livestock” on property around Sharon Reservoir “as early as 1917” and that they grazed and watered the stock.
¶9 The Water Court found as undisputed facts that the preceding four reservoirs were developed by the BLM and that the BLM’s claimed priority date for each stockwater right is the date the reservoir was completed. The BLM does not own livestock, but provides the water for use by grazing permittees and others. The Water Court found that the reservoirs have been “consistently used for stockwatering since they were completed.”
¶10 The Water Court found that it was undisputed that none of the Objectors or their predecessors filed claims for stockwatering from any *124of the sources of water that are impounded in the reservoirs. The exception is the claim filed by Lela and William French, claim 40M 169526-00, for stockwater from the North Flat Creek Reservoir.
¶11 The Water Court noted that the common law elements of a valid (use right) appropriation of water are intent to appropriate, notice of the appropriation, diversion and beneficial use. In the Matter of the Adjudication of Existing Rights (Bean Lake III), 2002 MT 216, ¶ 10, 311 Mont. 327, 55 P.3d 396. Prior to 1973 an appropriator in Montana could secure a water right simply by putting the water to a beneficial use. Mont. Trout Unlimited v. Mont. DNRC, 2006 MT 72, ¶ 5, 331 Mont. 483, 133 P.3d 224. The Water Court concluded that impoundment of water in a reservoir is a sufficient diversion of water to support a claim to a use right of water under Bean Lake III, and noted that the Objectors contested only whether the BLM had applied the water to a beneficial use. The Objectors contended that since the BLM did not own any livestock of its own, it did not use water from the reservoirs and therefore could not have perfected the stockwatering claims under Montana law.
¶12 The Water Court resolved this issue by applying this Court’s venerable opinion in Bailey v. Tintinger, 45 Mont. 154, 122 P. 575 (1912), relied upon by both the BLM and the Objectors. Bailey established that a person, association or corporation could appropriate water under Montana law “to sell, rent, or otherwise dispose to others.” Under the principles of the Bailey case, an appropriation of water for the use of others was complete upon completion of the diversion system (in this case the reservoirs) and making the water available for use by others. Bailey, 45 Mont. at 166-67, 122 P. at 579. The Water Court concluded that these principles applied to appropriations by the United States and that ownership of stock was not required to complete the appropriation. Finally, the Water Court determined that participation by non-governmental parties in the construction or maintenance of some of the reservoirs did not affect the validity of the BLM claims because Montana law recognizes that multiple claims may exist in the same source of water. St. Onge v. Blakley, 76 Mont. 1, 23, 245 P. 532, 536 (1926); Mont. Trout Unlimited, ¶ 7.
¶13 The BLM acquired the Funnells Reservoir (Claim 40M 74655-00) in 1951 when it acquired some of the surrounding property. At that time the dam was in place providing 1.2 acre feet of water storage. The BLM claims a priority date in this reservoir of August 1945. A portion of the reservoir is on Barthelmess land, and Barthelmess filed a stockwater claim in the reservoir. Barthelmess also contends that its *125ancestral free grazers had stock in the area around Funnells as early as 1915. The Water Court found as an undisputed fact that the reservoir has been used for stockwater consistently since the BLM acquired its interest in the property.
¶14 The Water Court concluded that under Montana law the BLM acquired any appurtenant water rights when it acquired the property. Section 85-2-403(1), MCA; Maclay v. Missoula Irrig. Dist., 90 Mont. 344, 353, 3 P.2d 286, 290 (1931). In addition, the Water Court rejected the Objectors’ argument that the BLM could not show when the reservoir was constructed or when it was actually used for stockwatering, and that the BLM water claim therefore could only date from when it acquired the property in 1951. The Water Court noted that this argument was inconsistent with the Objectors’ own contention that they derived rights from their ancestral free grazers who had grazed animals in the same area since 1915. In addition, the Water Court held that under Montana law a statement of water right claim is primafacie evidence of its content, § 85-2-227, MCA, and Teton Co-Op Canal Co. v. Teton Coop Reservoir Co., 2015 MT 344, ¶ 20, 382 Mont. 1, 365 P.3d 442, and that the Objectors had not carried their burden to prove that essential elements of the BLM water right claim were incorrect. As was the case with the prior BLM reservoirs, the Water Court noted that under Montana law two parties can claim ownership in water rights from the same source.
¶15 Pothole Lake (Claim 40M 74579-00) is a natural feature2 located on BLM land that has been available for use by others. The Objectors, for example, claim that Frenches or their ancestral free grazers grazed stock in the area of the Pothole as early as 1917. The BLM claims a reserved water right in the Pothole with a priority date of April 1926. The claim of a reserved right is based upon the Stock Raising Homestead Act (SRHA) enacted by Congress in 1916 and the Public Water Reserve (PWR) No. 107 signed by the President in April 1926. The SRHA allowed the Secretary of the Interior to reserve lands that “contain waterholes or other bodies of water needed or used by the public for watering purposes.” 43 U.S.C. § 300 (1912). The subsequent PWR 107 reserved all springs and water holes on vacant, unappropriated, and unreserved public land throughout the country. The Water Court found that the Pothole Lake was part of the reservation of land and water provided for by PWR 107.
*126¶16 The Objectors contended as to all of the BLM claims, that their ancestral free grazers grazed the land and watered their stock in the available water sources long prior to construction of any of the BLM reservoirs. The Objectors contend that they thereby obtained the sole and paramount right to all of the waters at issue in this case and that any BLM claims to water should therefore be transferred to them.
¶17 The Water Court concluded that any stockwatering by the Objectors’ ancestral free grazers were direct uses from the water sources, unaided by reservoir impoundments, and are therefore separate from the subsequent BLM reservoir claims. The governing principle of water law is that the existence of a prior right or claim in a particular water source does not preclude appropriation of subsequent rights from the same source. St. Onge, 76 Mont. at 23, 245 P. at 536; Mont. Trout Unlimited, ¶¶ 7-8. This principle is at the core of appropriation water rights under Montana law, allowing multiple appropriators to enjoy rights from the same source of water. The Objectors’ claim that prior use by their ancestral free grazers precludes later claims by the BLM or any other person or entity is contrary to the precepts of prior appropriation.
¶18 The Objectors also argued that prior Water Court decisions support their argument that they should be given title to the right to use the water stored in the BLM reservoirs.3 The Water Court disagreed with the Objectors’ construction of these decisions. Construing its own decisions, the Water Court found that “neither case addressed any restriction on BLM ownership of stock claims on federal land or found that stock rights on federal land must be owned by permittees.” In addition, one of the cases “recognizes that stock rights on federal land are routinely owned by the BLM.”
¶19 In addition to BLM stockwater claims, the BLM also claimed the right to provide water for wildlife at each of the reservoirs and the Pothole Lake. The Objectors argued that any wildlife use was only incidental to stockwatering, and that the BLM never intended to appropriate water for wildlife, never gave notice of any intent to do so, and never took steps to put water to use for wildlife, thereby precluding any claim under Montana law. The Water Court disagreed, finding that claims for fish, wildlife and recreational use are recognized by Montana law, and that no diversion is required when a diversion is *127not necessary for the wildlife use. Bean Lake III, ¶ 40.
¶20 The Water Court determined that the nature and extent of a water claim for wildlife use “depends on the specific facts surrounding the claimed appropriation” and that wildlife claims must be supported by evidence of intent to appropriate, notice of intent and application of the water to a beneficial use. The Water Court relied upon statements by Congress referencing management of BLM lands for stock and for wildlife as showing intent to do so. In addition, publication of these Congressional statements and enactments gave notice that the BLM intended to appropriate for wildlife. The Water Court found that developing the reservoirs was sufficient appropriation to consummate a right for wildlife uses. Because wildlife uses require less water than consumptive uses such as stockwatering, adding wildlife uses to each of the reservoirs did not expand the amount of water claimed. Therefore, as to the four reservoirs constructed by the BLM, there was sufficient proof of a water right for wildlife.
¶21 As to the Funnells Reservoir, the BLM acquired it as a constructed facility in 1951. The Water Court found that the same Congressional enactments that supported a wildlife claim for the first four reservoirs, constructed by BLM, also supplied the required intent for Funnells. While Funnells was originally constructed for stockwatering, the Water Court found that when the BLM acquired it in 1951, wildlife had already benefitted from its water, and after that time it was also managed for wildlife use. This represented a change in the stockwater right the BLM acquired with the reservoir. The law in effect at the time of this change, § 89-803, RCM (1947, repealed in 1973), required no prior approval for a change in use, and the wildlife claim did not represent a new appropriation because it did not expand the amount of water used. Therefore under that statute the Water Court determined that the priority date for the wildlife use related back to the priority of the original appropriation in 1945, before the BLM acquired the facility.
¶22 As to the Pothole Lake, the Water Court determined that there are factual issues that remain to be decided concerning the wildlife claim for that water source. The Water Court remanded the wildlife portion of the Pothole Lake claim to the Water Master for further proceedings.
¶23 The Water Court last determined that the volume of water for each of the BLM claims remained unresolved. While the BLM argued that the Objectors had not refuted its volume claims, the Water Court accepted the Objectors’ argument that they had not been given a full and fair opportunity to present evidence as to the volume of water that *128should be decreed to each of the BLM storage claims. Therefore the Water Court remanded all of the BLM claims to the Water Master for further proceedings on the volume of each of the BLM storage claims. ¶24 The Objectors appeal.
STANDARD OF REVIEW
¶25 This Court recently set out the standards of review in an appeal from the Water Court’s review of a Water Master’s report. Heavirland v. State, 2013 MT 313, ¶¶ 13-16, 372 Mont. 300, 311 P.3d 813; Skelton Ranch v. Pondera County Canal & Res. Co., 2014 MT 167, ¶¶ 25-27, 375 Mont. 327, 328 P.3d 644. In summary, the Water Court reviews the Water Master’s findings of fact under the “clearly erroneous” standard, and reviews the Water Master’s conclusions of law to determine whether they are correct. This Court reviews the Water Court’s decision under the same standards as applied to the review of District Court decisions.
DISCUSSION
¶26 Issue One: Whether the Water Court erred in concluding that the United States Bureau of Land Management (BLM) holds stockwatering rights under Montana law in reservoirs constructed on federal land, for the use of grazing permittees.
¶27 The Objectors argue that the BLM did not properly perfect state law water rights in the reservoirs and so may not maintain claims in the adjudication process.4 As noted above, perfecting a water appropriation claim in Montana prior to 1973 required an intent to appropriate, notice of the appropriation, diversion and beneficial use, Bean Lake III, ¶ 10. While the Objectors acknowledge that Montana law allows an appropriator to appropriate water for sale or distribution to others, they contend that the BLM does not qualify to do so. The Objectors also contend that the BLM never applied water to a beneficial use because it did not own any livestock and therefore could not have perfected the stockwatering claims.
¶28 The parties argue that Bailey either supports or defeats the BLM water claims. A primary issue in Bailey was whether a person could appropriate water under Montana law “to sell, rent, or otherwise dispose to others” without otherwise using the water himself. This Court in Bailey held that Montana law recognized that an *129appropriation of water to be used by others was complete upon construction of the diversion system (such as a reservoir) and making the water available to others. Bailey, 45 Mont. at 166-67, 122 P. at 579. This Court recently explained the holding in Bailey.
The appropriation of water for sale has long been accepted as a beneficial use. Our first Constitution in 1889 explicitly recognized the right to sell and rent water to others as a beneficial use. Mont. Const, art. III, § 15. The verbiage used in the 1889 Constitution referencing the sale of water was imported almost verbatim nearly one hundred years later into the 1972 Constitution. Compare Mont. Const. art. IX, § 3 with Mont. Const, art. III, § 15 (1889). This constitutional provision, along with its interpretations in our case law, clearly shows a steadfast commitment to recognizing the ability to appropriate water for its ultimate use by a third party.
Curry v. Pondera County Canal & Reservoir Co., 2016 MT 77, ¶ 25, 383 Mont. 93, 370 P.3d 440 (internal citations omitted). The Water Court in the present case concluded that these principles applied to appropriations by the United States, and that Montana law did not require that the BLM own and graze livestock to perfect a water right. ¶29 The Objectors next argue that Bailey established a rule that only a “public service corporation” can appropriate water for use by third parties. The Objectors argue that since the BLM is not a “public service corporation” it cannot perfect its claims to appropriate water for the use of others under Montana law. An examination of the Bailey Opinion shows that the Objectors misconstrue its holding.
¶30 The dispute in Bailey involved water right claims in Big Timber Creek. In 1892 three individuals commenced work on an appropriation of water, some for their own use and the rest to “sell, rent, and otherwise distribute” to others. One of those individuals, named Hatch, succeeded to the interests of his former partners in the appropriation; an individual named Wormser succeeded to Hatch’s interests; and a subsequently-organized canal company succeeded to the interests of Wormser. The canal company continued to construct miles of canals and ditches to distribute the water to customers, and its interests were acquired by yet another company. By 1910 the original appropriation by Hatch and his partners was being used to distribute water to others who were irrigating about 1000 acres. A controversy arose with other appropriators over whether successive enlargements to the capacity of the system were new appropriations or whether they related back to the original Hatch appropriation in 1892.
¶31 The Bailey Opinion traced the history of Montana law relating to *130the appropriation of water, Bailey, 45 Mont. at 166-75, 122 P. at 581-82, concluding that since 1877 Montana law “specifically recognized the right of an individual to appropriate water to rent or sell to another.” Bailey, 45 Mont. at 174, 122 P. at 582 (emphasis added). The Bailey Court noted that since 1907 it has “been held that the appropriator need not be either an owner or in possession of land in order to make a valid appropriation for irrigation purposes.” Bailey, 45 Mont. at 175, 122 P. at 582. Further:
In cases of appropriation for the purpose of supplying water to others, we do not understand how it can be said that the use of the water is an essential element of its appropriation. If the intended appropriator constructs the works and appliances necessary for the diversion of the water and the carrying of it to points where its use is desirable and profitable, and has actually carried it there, or is ready and willing to do so and offers it to all persons who are willing to pay for its use, we apprehend that his appropriation is complete.
Bailey, 45 Mont. at 177, 122 P. at 583. The Bailey Court warned that unless such appropriations were allowed it would “retard the reclamation of arid lands” in areas where the “magnitude of the undertaking is too great for individual enterprise.” The Court warned that failure to adopt such a policy could also defeat the land reclamation goals of the United States in making appropriations “as a corporation or individual” for use by others. Bailey, 45 Mont. at 177, 122 P. at 583.
¶32 The Bailey Court then declared it the public policy of the State of Montana to encourage “public service corporations” to appropriate water for sale, rental or distribution to others. Bailey, 45 Mont. at 177, 122 P. at 583. The Bailey Court did not define “public service corporations.” At the time the Bailey case was litigated the entity that owned the original Hatch appropriation from Big Timber Creek was called the “Glass-Lindsay Land Company.” The Bailey Opinion stated that Glass-Lindsay was “organized under the laws of this state” with the “authority to purchase or construct an irrigation system and to sell, rent or otherwise dispose of water.” Bailey, 45 Mont. at 161, 122 P. at 577. The Objectors assume from this that Glass-Lindsay was organized as a corporation under Montana law and that organization as a corporation under Montana law was therefore a vital prerequisite to appropriating water for the eventual use by others.
¶33 This assumption is not warranted by the Bailey Opinion, which clearly did not limit appropriations for sale or use by others to “public *131service corporations.” Critically, the Objectors’ construction of Bailey overlooks the fundamental fact of the case that the appropriation at issue there was commenced by three individuals; was then owned by one of those individuals; and was then owned by another individual before the canal companies got involved. The actual water right at issue in Bailey was therefore initiated by individuals, and not by a “public service corporation.” It is also significant that the priority date for the appropriation in Bailey related back to the date that the three individuals put the water to use, and was not the later date when the canal companies appeared. Regardless of the fact that the Bailey Opinion referred to the entity holding the appropriation at the time of the opinion as a “public service corporation,” that entity was holding an appropriation initially established by individuals. And, significantly, the Bailey Opinion, as noted, expressly recognized the right of the United States to proceed under Montana law to appropriate water to sell, rent or otherwise dispose of to others.
¶34 Under the law established in Bailey, there is no “public service corporation rule,” but only the recognition of a public policy of the state of Montana to allow and even encourage individuals and entities who are able to do so to appropriate water and make it available for use by others. Curry, ¶ 25. We also reject as being without support, the Objectors’ argument that the BLM cannot appropriate water under Montana law because it does not separately charge grazers for the use of the reservoir water. Charging money for the water is not a requirement of perfecting a water right for “sale, rental or disposal to others.” As long as the water is made available for sale, rental, or distribution or disposal to others, it is a valid appropriation under Bailey. As we recently held, Montana law “clearly shows a steadfast commitment to recognizing the ability to appropriate water for its ultimate use by a third party.” Curry, ¶ 25.
¶35 The Dissent argues that the BLM has never put water to a beneficial use. To the contrary, recognition that storage of water as BLM has done is a beneficial use is expressly provided by the Montana Constitution: “The use of all water that is now or may hereafter be appropriated for sale, rent, distribution, or other beneficial use ... and the sites for reservoirs necessary for collecting and storing water shall be held to be a public use.” Mont. Const. art. IX, § 3(2); Curry, ¶¶ 31-33. We agree with the Water Court that the BLM was entitled to proceed under Montana law to appropriate water in its reservoirs for use by grazing permittees and others.
¶36 The Objectors also argue that the BLM claims are invalid because *132the BLM did not appropriate any water, but “simply facilitated use of water already appropriated” by their ancestral free grazers in the early 20th century. This argument cannot be supported under Montana water law. First, as previously noted, it has long been the common law and then statutory law in Montana that multiple appropriators can claim water rights from the same source, and that the first in time has the best right. It is well known that there have been so many different appropriators on some water sources that the waters have become “over appropriated” in that the amount of water claimed by all the appropriators far exceeds the water actually available. Mont. Trout Unlimited, ¶¶ 7-8. While over-appropriation creates its own issues, it does not mean that the person or entity that made the first use on a water source acquired the right to exclude any other person or entity from claiming water from the same source. Far from it, as we have said, a fundamental precept of Montana water law is that multiple claims can exist on a single source of water. Adopting the Objectors’ position would cause chaos in Montana prior appropriation law. Senior appropriators could claim not just that they had the earliest right to use water in a stream, but also that no one else could claim rights from that stream because the senior appropriators were there first—an argument contrary to the fundamental precepts of prior appropriation law. Federal Land Bank v. Morris, 112 Mont. 445, 456, 116 P.2d 1007, 1012 (1941).
¶37 The BLM is not claiming water rights based upon any ancestral free-grazer stockwater use in the early years of the twentieth century such as that cited by the Objectors. The BLM claims are clearly based upon subsequent appropriations via reservoir construction. The earliest BLM claim in this case is 1926 (Pothole Lake) and the latest is 1961 (Sharon Reservoir). If the Objectors hold any viable stockwatering claims based upon water use in the first decades of the twentieth century, those rights are separate from and clearly would be senior to, any reservoir rights claimed by the BLM.5 As the Water *133Court concluded, those early water uses were direct from the source, unaided by any reservoir storage. Any right arising from the ancestral free grazing before World War I is separate from the later BLM reservoirs, and the existence of prior rights does not preclude subsequent appropriation of water from the same sources. Each right has its own priority in time.
¶38 Second, the Objectors contend that the BLM’s construction of the reservoirs “did not constitute a new appropriation” but “simply modified” the prior stockwatering practices by their ancestral free grazers. It is certainly true, as the Objectors concede, that a direct-flow water user can add a reservoir to stabilize the available water so that it can be used throughout the year, without creating a new appropriation. Teton Cooperative Res. Co. v. Farmers Cooperative Canal Co., 2015 MT 208, 380 Mont. 146, 354 P.3d 579. This is not what happened in the case of the BLM reservoirs. The BLM does not claim any earlier direct-flow water rights. It claims only new rights to stored water, with appropriation dates in the mid-twentieth century. Contrary to the Objectors’ argument, this situation is materially different from the one considered in Teton. Additionally, In Granite County v. McDonald, 2016 MT 281, 385 Mont. 262, 383 P.3d 740, decided November 3, 2016, we upheld the water right of a subsequent reservoir owner to impound water on a stream as long as it did not interfere with the senior rights of downstream direct-flow users. In fact, that relationship had been recognized by a water right decree entered in 1906. This, and not Teton, represents the present situation with regard to the BLM reservoirs and the rights, if any, deriving from ancestral free grazers. The BLM rights are separate rights with their own priority dates.
¶39 We emphasize that the foregoing analysis of the Objectors’ claims is based upon fundamental and long-established principles of Montana water law. The first in time is the first in right, and multiple persons may therefore perfect claims to water from the same source as is the case across the breadth of our State. Ignoring this fundamental principle to uphold the Objectors’ claims in this case would throw Montana water rights into chaos. Water use by the Objectors’ ancestral free grazers does not, under established Montana law, preclude the *134BLM or any other person or entity from making a claim of water right in the same source. Further, it could not be more clear that for over one hundred years Montana has recognized the right of individuals and entities to appropriate water for the sale, rental, or distribution to others. There is no “public service corporation” limitation upon this important principle of law. It has long been the public policy of Montana to recognize and encourage the benefits to agriculture and stock raising that flow from allowing appropriations that make water available for the use of others. We are unwilling to depart from these bedrock principles of Montana water law in this case. Finally, the principle of loss by “nonuser” (Dissent ¶ 66, quoting Bailey), is not an issue in this case and the Water Court has yet to adjudicate the quantity of the BLM rights.
¶40 Because we agree with the Water Court that the BLM has valid appropriations under Montana law, and that there is no basis in fact or in law to assign ownership of the BLM claims to the Objectors, we decline to consider the Objectors’ arguments concerning the authority of the Water Court to do so.
¶41 Issue Two: Whether the Water Court erred in granting partial summary judgment on the Pothole Lake claim when there were genuine issues of material fact.
¶42 The Water Court noted that the Objectors did not challenge the fact that PWR 107 can serve as the basis for a reserved stock water right on federal land. In fact, it is well established that the SRHA and PWR 107 provide a valid basis upon which the federal government can support claims to reserved water rights. Other state courts have recognized the validity of these claims in their water adjudication processes. United States v. Denver, 656 P.2d 1, 32 (Colo. 1982) (Court agreed that the federal government has “reserved rights to provide a watering supply for animal and human consumption ... so that no person could monopolize or control vast areas of western land by homesteading the only available water supply.”); United States v. Idaho, 959 P.2d 449, 452 (Idaho 1998) (“After considering the plain and ordinary words of the enabling statutes and executive order underlying PWR 107, we conclude that PWR 107 evidences an express intention by Congress that reserves a water right in the United States.”)6 These *135courts recognized that giving a single party control of these reserved water sources could lead to the monopolization of the water and surrounding land, contrary to the express intent of Congress.
¶43 The Objectors’ challenge to the Pothole Lake water claim is based upon arguments that it is too small to qualify for reservation under PWR 107; that the BLM has never listed the Pothole in its inventory of such reserved water sources; and that the BLM did not present this claim to the Montana Reserved Water Rights Compact Commission. The Objectors cite a federal regulation from 1980 which states that the reservation provisions of SRHA and PWR 107 should not be applied to “small springs or water holes affording only enough water for the use of one family and its domestic animals.”7 The Water Court noted that while the Objectors contend that the Pothole is too small to qualify for reservation, at the same time they contend that they and their ancestral free grazers have grazed stock there since the early twentieth century. They also contend that the Pothole right should be transferred to the Objectors for the same stockwater use. These inconsistent positions, the Water Court concluded, undermined the Objectors’ position on this claim.
¶44 The original PWR 107 in 1926 reserved “every spring or waterhole, located on unsurveyed public land.” (Emphasis added.) The broad language of the reservation clearly included this Pothole Lake and there is nothing to indicate that the original reservation has been reversed. The Objectors misconstrue the 1980 regulation language that they rely upon. That regulation did not retroactively unreserve water sources like the Pothole Lake that had been reserved since 1926. Rather, the regulation implemented statutory changes that Congress made in 1976, intended to limit future reservations of federal land. United States v. Idaho, 959 P.2d at 453. The regulation that the Objectors rely upon has no effect upon the original intent of SRHA and PWR 107 and does not provide any support for an argument that the property has been unreserved. The BLM’s failure to inventory this Pothole was likewise not significant in light of the original withdrawal, and while the BLM could have submitted its claim to the Reserve *136Water Right Compact Commission, it was not required to do so.
¶45 We agree with the Water Court’s conclusion that the Pothole Lake was properly reserved by an act of Congress in 1926 and that nothing raised by the Objectors supports any change in that status. We find no evidence that the Water Court made any determination based upon contested issues of material fact. The Water Court denied summary judgment as to the volume of each of the BLM claims and remanded to the Water Master for further proceedings to resolve those issues.
¶46 The decisions of the Water Court are affirmed.
JUSTICES COTTER, WHEAT, BAKER, SHEA and RICE concur.Federal law recognizes the jurisdiction of state courts to resolve federal water rights claims. 43 U.S.C. § 666; Confederated Salish & Kootenai Tribes v. Clinch, 2007 MT 63, ¶¶ 12-13, 336 Mont. 302, 158 P.3d 377.
A “pothole” in this context usually describes a natural depression in the landscape that contains water.
Edwards v. BLM, Water Court Case No. 40E-A (Water Court Opinion June 29, 2005); Hamilton Ranches v. BLM, Water Court Case No. 41G-190 (Water Court Opinion July 19, 2005).
This argument excludes the claim for the Pothole Lake, which is not a claim based in state law.
The Objectors assert, and the Water Court seems to have agreed, that their ancestral free grazers utilized water on public lands to water their stock a hundred or more years ago. However, at least in the briefing in this appeal, the Objectors do not cite any specific water right claim based upon this historic stockwatering. The Water Court noted that at least as to claims to water in the BLM reservoirs, Montana law required that the Objectors file their claims by July 1, 1996, at the latest, and that if they failed to do so, they lost their right to make such claims. Section 85-2-226, MCA; Matter of the Adjudication of Water Rights in the Yellowstone River, 253 Mont. 167, 175, 832 P.2d 1210, 1214 (1992). The Water Court specifically held, however, that under § 85-2-222(1), *133MCA, failing to file on in-stream stockwater uses is optional and that the Objectors could still voluntarily file claims on those rights if they choose to do so. The Objectors do not expressly claim that the BLM claims are objectionable because the reservoirs interfere with the Objectors’ prior rights to water.
Reserved water rights were recognized in Winters v. United States, 207 U.S. 564, 28 S. Ct. 207 (1908), a case arising from Montana, holding that when Congress established Indian reservations it impliedly reserved sufficient water to satisfy the purposes of that reservation, with a priority date as of the creation of the reservation. *135This concept has been extended to include all types of federal reservations of land. Cappert v. United States, 426 U.S. 128, 138, 96 S. Ct. 2062 (1976).
The Objectors contend that State guidelines provide that a single family requires 1.5 acre feet of water per year, which is slightly more than is supplied by the Pothole. This guideline provides no authority that this Pothole Lake is no longer part of the reserved lands of the United States.
