delivered the Opinion of the Court
This appeal is from a judgment of the District Court for Water Division No. 2 (Water Court) dismissing an application for change of use of two water rights. Appellant Santa Fe Trail Ranches Property Owners Association (Santa Fe Ranches) raises a single issue for review:
Whether diversions made pursuant to a decreed water right, although not used for decreed uses, may be considered as establishing historical use for the purpose of a change of water right proceeding, if the Water Commissioner was aware of the diversions and did not order their discontinuance or curtailment.
The Water Court answered this question as follows:
Diversions made pursuant to a decreed water right, when not used for decreed uses, may not be considered as establishing historical use for the purpose of a change of water right proceeding, regardless of whether the water commissioner was aware of such diversions and did not order their discontinuance or curtailment.
We affirm the Water Court’s judgment dismissing the application.
I.
Santa Fe Ranches sought to change the use of two water rights appropriated by the Colorado Fuel and Iron Company (CF & I): (1) the Antonio Lopez at El Moro right for 0.25 c.f.s. decreed for manufacturing use,
CF & I’s appropriations occurred in connection with its production of coking coal amidst the coalfields in southern Colorado that helped to supply CF & I’s steel plant in Pueblo.
From 1966 to 1985, CF & I leased its interest in the two water rights at issue in this case to the El Moro Ditch Company (El Moro Ditch), which used the water for irrigation of lands under the El Moro Ditch.
Santa Fe Ranches seeks by its application to change both of the CF & I rights from manufacturing to “municipal, domestic, commercial, industrial, irrigation, stock water, recreation, fish, wildlife, and fire protection, exchange, augmentation, and reuse and successive uses until such water has been entirely consumed.” The principal use of the water would be for augmentation of depletions from three wells to serve as a central water supply for a 459-lot subdivision, located south of the City of Trinidad and immediate
No prior change proceeding has determined the historic use of the two CF & I rights. In the Water Court, Santa Fe Ranches stated that it could not demonstrate CF & I’s historic use of these rights and sought, instead, to rely on the use of them for irrigation under the El Moro Ditch from 1966 to 1997. It claimed 41.4 acre-feet of consumptive use annually for the Antonio Lopez at El Moro right and 12.6 acre-feet consumptive use annually for the El Moro Pipeline right.
The points of diversion for the CF & I rights and the El Moro Ditch rights are across the Purgatoire River from each other; CF & I’s manufacturing use was made south of the river, while the irrigation use was made north of the river. The El Moro Ditch is one and a half miles long and irrigates 184 acres, of which the water commissioner for the area owns ninety-five acres. Half of the water diverted under the CF & I rights went to his own land. He testified by deposition in the Water Court that he was unaware of the decreed use of the CF & I rights, and that neither he, nor the division engineer, curtailed the irrigation diversions: “It never crossed my mind that it wasn’t used for, or couldn’t be used for irrigation.” He also testified that CF & I’s use of its rights may have ceased “maybe 30, 40 years prior” to 1966.
In his affidavit, Ralph Adkins, the CF & I employee who arranged the CF & I lease with the El Moro Ditch, stated that CF & I had maintained records of its use but these had disappeared:
I personally know that CF & I kept records of use of their water rights, including these, to assure that it could document their continued use. I have attempted to research the CF & I records, but find that CF & I has, after my departure from the company, either destroyed or misplaced all its records on these water rights.
He also stated that CF & I did not intend to abandon the water rights, that the water commissioner was aware of their diversion for irrigation and had not ordered curtailment, and that CF & I’s successor in interest to the rights held them “for the purpose of sale and also did not intend to abandon these water rights.”
The state and division engineers continued to oppose the application after the City of Trinidad and the Purgatoire River Water Conservancy District withdrew their statements of opposition. In his affidavit, Dick Wolfe of the State Engineer’s Office stated that, “The Purgatoire River is severely over-appropriated. Water rights junior to 1898 generally do not receive a reliable water supply.” In light of the lack of information concerning the historic use of CF & I’s manufacturing rights, the engineers contended that the proposed change of use might enlarge the water rights, to the injury of others.
Asserting that use of the water for irrigation under the El Moro Ditch pursuant to the lease can properly serve as the basis for calculating the historic use of the CF & I water rights, Santa Fe Ranches submitted the following determinative question of law to the Water Court pursuant to C.R.C.P. 56(h):
Whether diversions made pursuant to a decreed water right, although not used for decreed uses, -may be considered as establishing historical use for the purpose of a change of water right proceeding, if the Water Commissioner was aware of the diversions and did not order their discontinuance or curtailment.
The Water Court answered this question in the negative, ruling that (1) historic use for the decreed use of the appropriation is determinative in a change proceeding, and (2) an undecreed change of use cannot be the basis for the historic use determination. It reasoned, in part, that:
*52 Since junior appropriators are entitled to maintenance of stream conditions at the time of their respective appropriations, the omitted proceeding for change of use to irrigation would find Applicant’s predecessor limited to any then existing and provable prior historic use. Applicant, these many years later, is unable to provide any information regarding quantity of historic use undertaken pursuant to the decreed uses of these rights.
In response, Santa Fe Ranches asked for dismissal of its application so that it could appeal the court’s ruling: “Regrettably, the Applicant simply has no additional evidence to present. Given the Court’s ruling, the applicant cannot meet its burden of proof at trial.” The Water Court then dismissed the application. We uphold the order and judgment of the Water Court.
II.
We hold that an undecreed change of use of a water right cannot be the basis for calculating the amount of consumable water that can be decreed for change to another use.
A.
Beneficial Use — The Basis, Measure, and Limit of an Appropriation
Santa Fe Ranches argues that (1) the water officials knew that the CF & I rights were being used for irrigation under the El Moro Ditch and did not curtail diversions for this purpose, (2) no other water users complained of injury because of the irrigation use, and (3) the undeereed use of the CF & I rights for irrigation under the El Moro Ditch is a proper basis for determining historic use in the change proceeding, and no injury to other water rights has or will occur thereby. This argument is contrary to longstanding beneficial use and adjudication law in this state; thus, we begin our analysis with a review of precedent.
Soon after statehood, which occurred in 1876, the Colorado Irrigation Convention of December 5-7, 1878, deliberated and passed resolutions addressing three problems: determination of priorities, distribution of water according to those priorities, and stream measurement. See Robert G. Dunbar, Forging New Rights in Western Waters 90 (1983). Dry years had brought the operators of the direct flow irrigation ditches on the Cache la Poudre River into conflict with each other. The upstream ditches were filling to the exclusion of downstream ditches that earlier had put the water to beneficial use. Some means was needed to fix and administer water right priorities. Resolutions of the irrigation convention led to the General Assembly’s adoption of the 1879 and 1881 Adjudication Acts that consigned the determination of water rights and their priorities to the courts and the administration of the courts’ judgments to water officials. See id. at 91-98; Act of Feb. 19, 1879, 1879 Colo. Sess. Laws 94-108 (providing for priority of rights to use of water for irrigation); Act of Feb. 23, 1881, 1881 Colo. Sess. Laws 142-61 (same).
The 1879 and 1881 Acts provided for the adjudication of irrigation rights only. The 1899 Act required adjudication for change of irrigation rights. See Act in Relation to Irrigation, ch. 105,1899 Colo. Sess. Laws 235-36. The 1903 Adjudication Act made the adjudication provisions applicable to all water rights, whatever their beneficial use. See Act Concerning Water Rights, ch. 130, 1903 Colo. Sess. Laws 297-98. The 1919 Act required the owners of all water rights to adjudicate their priorities, upon penalty of forfeiture. See Irrigation, Settling Priorities to Water, ch. 147, § 8,1919 Colo. Sess. Laws 494-95. The 1943 Act provided for original and supplemental adjudications, including adjudications for changes of water rights. See Act Relating to the Waters of the State of Colorado, ch. 190, §§ 22-24, 1943 Colo. Sess. Laws 628-31. The 1969 Water Right Determination and Administration Act established an application, resume notice, and determination procedure for water rights, including changes of water rights.
Contrary to Santa Fe Ranches’ contention that a change of use proceeding focuses only on injury to other water rights, the continuous stream of Colorado water law demonstrates that change of use involves two primary questions: (1) What historic beneficial use has occurred pursuant to the appropriation that is proposed for change? and (2) What conditions must be imposed on the change to prevent injury to other water rights? Only when these questions are satisfactorily addressed may the water court turn to consideration of the terms for a decree approving the change of use.
These basic predicates for a change of use have their roots in nineteenth-century water rights law, which provided that: (1) the extent of beneficial use of the original appropriation limits the amount of water that can be changed to another use, and (2) the change must not injure other water rights.
By his legal appropriation of the amount of water sufficient for his original purpose he is entitled to that amount and may apply it to any of the beneficial uses he may see fit, as against other parties whose rights have accrued subsequently to his own, “provided, the amount of water taken by him is not thereby increased beyond that of his original appropriation, nor the rights of those coming later injured or impaired in any manner.
See Clesson S. Kinney, A Treatise on the Law of Irrigation 375 (1894) (emphasis added).
The property right we recognize as a Colorado water right is a right to use beneficially a specified amount of water, from the available supply of surface water or tributary groundwater, that can be captured, possessed, and controlled in priority under a decree, to the exclusion of all others not then in priority under a decreed water right. See Shirola v. Turkey Cañon Ranch Ltd. Liab. Co.,
“Appropriation” is “the application of a specified portion of the waters of the state to a beneficial use pursuant to the procedures prescribed by law.” § 37-92-103(3)(a), 10 C.R.S. (1999). The 1969 Act defines “beneficial use” as “the use of that amount of water that is reasonable and appropriate under reasonably efficient practices to accomplish without waste the purpose for which the appropriation is lawfully made.”
“ ‘Water right’ means a right to use in accordance with its priority a certain portion of the waters of the state by reason of the appropriation of the same.” § 37-92-103(12), 10 C.R.S. (1999). The purpose of adjudication is to fix the priority of a water right for its decreed uses so that it can be administered vis-a-vis all other decreed water rights. “The value of a water right is its priority and the expectations which that right provides.” Navajo Dev. Co. v. Sanderson,
The appropriator may transfer the water right to another use, see Strickler v. City of Colorado Springs,
Property rights in water are usu-fructuary; ownership of the resource itself remains in the public. See Farmers High Line Canal & Reservoir Co. v. City of Golden,
These limitations advance the fundamental principles of Colorado and western water law that favor optimum use,
Quantification of the amount of water beneficially consumed in the placement of
With this precedent in mind, we turn to its application in this case.
B.
Change of Use Proceeding
Santa Fe Ranches seeks to dispense with the basic requirement of a change of water right proceeding that requires the proponent of the change to identify the extent of actual beneficial use of the decreed appropriation at its place of use. This it may not do. Our decision in Orr v. Arapahoe Water & Sanitation District,
[A] senior appropriator is not entitled to enlarge the historical use of a water right by changing the point of diversion and then diverting from the new location the full amount of water decreed to the original point of diversion, even though the historical use at the original point of diversion might have been less than the decreed rate of diversion.
Orr,
Orr illustrates the primary function of the historical use limitation set forth by our precedents and section 37-92-305(4)(a). With its application, notice, and judicial determination requirements, change of water right adjudication serves to restrict an appropriation to the amount of its perfected use, while also allowing the priority of the right to be utilized for different uses and at different locations. See James N. Corbridge, Jr. & Teresa A. Rice, Vranesh’s Colorado Water Law, Revised Edition 245-51 (1999). In this manner, Colorado law promotes both security for water rights and flexibility for new uses and transfers of existing rights.
Santa Fe Ranches argues that our decision in Southeastern Colorado Water Conservancy District v. Rich,
Thus, there was no question in Rich regarding a possible enlargement of the water right, or total or partial abandonment of it; the trial court found the change to the alternate point of diversion to be inconsequential. The objector there challenged the validity of the diversions made at the original.point of diversion because they were made at a time when a legal call by senior rights on the river was in effect. We emphasized that the' diversions through the original point of diversion, upon which the appropriator’s absolute decree was based, had been allowed under the futile call provisions of the engineer’s authority. See §§ 37-92-501, -502(2)(a), 10 C.R.S. (1999); Rich,
Of significance here, two ingredients of the facts of Rich were essential to our holding: first, no statement of opposition was filed in. the prior case and the absolute right for the surface diversion had become final and was res judicata that the necessary steps had been completed to effect an appropriation, see Rich,
In contrast to Rich, where the decreed use of the appropriation and its place of use did not change, the use that Santa Fe Ranches invokes as historic use was neither for the decreed purpose of the CF & I appropriation nor was it made at CF & I’s place of use. The State and Division Engineer objected on the basis of possible enlargement of the CF & I rights. As applicant for a change of use, Santa Fe Ranches had the duty to establish actual usage of the CF & I appropriations it proposed to change. See Weibert,
The degree of consumptive use historically made of a manufacturing right turns on the requirements of the particular enterprise and how it actually applied and consumed the water. Water that is not beneficially consumed in the course of using the native water is not part of the allowable consumptive use allocation of the right for change purposes. See Williams,
Ascertaining the timing and quantity of the actual usage of the CF & I appropriations is critical to determining under section 37-92-305(3) whether the proposed change of water right or plan of augmentation will “injuriously affect the owner of or pei’sons entitled to use water under a vested water right or a decreed conditional water right.” The change must be approved if it will not cause injury. See § 37-92-305(3). Having been put to its proof on the question of injury due to a possible enlargement of the CF & I rights, Santa Fe Ranches defaulted in its duty of going forward on the historic use and injury issues. A change of water right must limit the amount of water being changed to the “same amount historically diverted through ... the original decreed points of diversion.” Orr,
Thus, in the course of demonstrating actual use of the CF & I rights, Santa Fe Ranches may not substitute diversions that occurred for an undecreed use of water, irrigation, made at another point of diversion, the El Moro Ditch, and place of use, lands under the El Moro Ditch. Only if a change of the two CF & I water light decrees had been obtained for the irrigation use under the El Moro Ditch would Santa Fe Ranches have been able to claim that consumptive use.
Inquiry into total or partial abandonment is also germane to a change of water right proceeding. The apparent thirty or forty year history of disuse of the CF & I rights at El Moro, to which the water commissioner referred in his deposition testimony, raised the inference that CFI’s right no longer existed or existed in a diminished amount. The intent to abandon a water right may be presumed due to a long period of disuse.
The purpose of Santa Fe Ranches’ application was to generate a decreed consumptive use quantification that it could employ as augmentation credit to replace deple-tions from wells operating out of priority at its subdivision’s central water system. To the extent that our decision in Rich suggests that exercise of the engineers’ enforcement discretion can relieve the change of water right applicant of its burden to establish actual usage of an appropriation for its decreed use at its place of use, we overrule any such implication as being contrary to Colorado law. “One of the basic tenets of Colorado water law is that junior appropriators are entitled to maintenance of the conditions on the stream existing at the time of their respective appropriations.” Bijou,
Santa Fe Ranches relies heavily on the water commissioner’s acquiescence in diversion of CF & I’s rights for the non-decreed irrigation use by the El Moro Ditch.
Starting with Colorado’s first adjudication acts, the Acts of 1879 and 1881, the General Assembly has consistently chosen to assign the water right determination function to the courts and the water distribution function to the water officials.
Here, the state and division engineers decided to participate in Santa Fe Ranches’ change proceeding, in order to monitor and enforce the historic use limitation. This is an appropriate exercise of the legislature’s authorization for participation by the engineers in water cases.
Our precedent supports the Water Court’s order rejecting Santa Fe Ranches’ claim to historic use of the CF & I rights under the El Moro Ditch for irrigation. Despite the diversion rate set forth in a decree, diversions are limited in quantity and time to those amounts that can be put to use for the decreed purpose at the water right’s place of use. See Rominiecki v. McIntyre Livestock Corp.,
Without evidence of CF & I’s utilization of the two rights at its El Moro
Santa Fe Ranches contends that a holding adverse to its position necessarily means that exchanges of water, leases of water, and other water management practices identified by Colorado statutes must be disallowed. We do not agree. The owner of a water right may lease, loan, or exchange water under the applicable statutes.
The question before the Water Court was whether an undecreed change of the two CF & I water rights can be the basis for decreeing a change of those rights, without regard to the amount of water consumed beneficially for CF & I’s original appropriation. The Water Court correctly refused to allow Santa Fe Ranches to substitute evidence of an un-decreed change to irrigation use under the El Moro Ditch for evidence of the historic manufacturing usage of the two CF & I water rights for its facility.
III.
Accordingly, we affirm the Water Court’s judgment dismissing Santa Fe Ranches’ change of water right application.
Notes
. The Purgatoire River country has a colorful history. The Spanish called the river "El Rio de Las Animas Perdidas en Purgatorio” ("The River of Lost Souls in Purgatory”); the French, "Pur-gatoire”; the Anglos, "Picketwire.” See David Lavender, Bent’s Fort 13-14 (1954).
. General William J. Palmer, builder of the Denver & Rio Grande Railroad, first established El Moro in 1875 as a railroad depot outside of Trinidad. See David Lavender, The Rockies 252 (1968). In 1876, he formed the Southern Colorado Coal & Town Co., acquiring 12,800 acres in the areas of Walsenburg and Trinidad. See Ralph C. Taylor, Colorado, South of the Border 433 (1963). Palmer then built the Pueblo steel plant where the first blast furnace went into operation on September 5, 1881, to begin producing rail for the burgeoning railroads of the western United States. See id. The steel operation led to building and operating the El Moro coke oven batteries located in Las Animas County. See id. at 434. A series of corporate name changes and mergers resulted in the incorporation of the Colorado Fuel and Iron Co. in 1892. See id. at 435-36. For the first three decades of the twentieth century, CF & I was the largest industry of the Rocky Mountain states, developing coal properties in Gunnison, Fremont, Huer-fano, and Las Animas counties and manufacturing steel rails at Pueblo. See id. at 436. As of 1941, CF & I’s Pueblo operation was the largest steel mill west of the Mississippi, with an annual capacity of 600,000 tons and the largest single industrial establishment in the state, employing 6000 to 7000 persons. See Colorado, A Guide to the Highest State, compiled by Workers of the Writers’ Program of the Work Projects Administration in the State of Colorado 75 (1941).

. The lease rate was $50 per year, $25 payable at the beginning of the irrigation season and $25 payable at the end of the irrigation season.
. No mention appears in the record as to whether or not diversion records of the various water commissioners in District No. 19 over the years contained information regarding exercise of the CF & I rights. Nor is there any explanation as to why the successors in interest to the CF & I rights did not obtain a copy of the CF & I records of use when they purchased the two rights.
. The 1969 Act repealed legislation that had established 70 water districts and substituted seven water divisions formed along major watershed boundaries for adjudication and administration of rights, each with a water court and a division engineer. See Act Concerning Water, and Enact
. This is the essential premise of appropriation law throughout the west. "Beneficial use is the measure and the limit of an appropriative right.” Joseph L. Sax, Robert H. Abrams & Barton H. Thompson, Jr., Legal Control of Water Resources, Cases and Materials, Second Edition 164 (1991).
. We held that water may be appropriated from one stream basin for beneficial use at a location in another stream basin. See Coffin, 6 Colo, at 450-51.
. Beneficial use, though an essential feature of the Colorado Constitution’s water provisions, see Colo. Const, art. XVI, § 6, is not defined or limited thereby. Rather, what constitutes a beneficial use tracks legislative enactments, court decisions, and, principally, the acts of appropriators who control the water to their purpose. See, e.g., State v. Southwestern Colorado Water Conservation Dist.,
. Importers of water that is foreign to the natural stream system have greater rights of use and reuse for beneficial purposes than do appropriators of native water. See § 37-82-106, 10 C.R.S. (1999); City of Thornton v. Bijou Irrigation Co.,
. See § 37-92-501(2)(e), 10 C.R.S. (1999) (providing that "all rules and regulations shall have as their objective the optimum use of water consistent with preservation of the priority system of water rights”); Alamosa-La Jara Water Users Protection Ass'n v. Gould,
. The availability of water arising in Colorado for beneficial use in Colorado is limited by the delivery requirements of the interstate compacts and equitable apportionment decrees to which Colorado is a party. See Simpson,
. Uses that would suffer from enlargement of senior rights include not only traditional irrigation, municipal, and industrial uses, but also federal reserved water rights and such newly evolved appropriative uses as fish and wildlife, snowmaking, recreation, boat chutes, nature center diversions, and stream augmentation for rafting flows. See, e.g., Board of County Comm’rs v. Upper Gunnison River Water Conservancy Dist.,
. The abandonment of certain water rights by CF & I in the Purgatoire River Valley due to its consolidation of operations at the Pueblo plant occurred under the facts of CF & I Steel Corporation v. Purgatoire River Water Conservancy District,
. Water rights are decreed to structures and points of diversion in recognition that a water right is a right of use and constitutes real property in this state, and the owners and users of water rights may change from time to time. See Dallas Creek Water Co. v. Huey,
. This action corrected what critics have lamented to be a major flaw of the Colorado system, that the state engineer was not allowed under the earlier Adjudication Acts to represent the public and question the accuracy of claims. See John E. Thorson, State Watershed Adjudications: Approaches and Alternatives, 42 Rocky Mt. Min. L. Inst. 22-8, -9 (1996).
. Nor does our holding affect utilization of the upstream storage and substitute supply provisions of section 37-80-120, 10 C.R.S. (1999). These provisions allow out-of-priority diversions under conditions statutorily designed to protect seniors against injury to their appropriations. The question in the case before us concerns the extent of the original appropriation for the purpose of quantifying transferable consumptive use in a change case and does not implicate statutorily recognized water management practices.
