¶1The appellants, plaintiffs below, filed an application with the state engineer for the appropriation of waters of the East fork of Lake fork of Green river, which has its source in Wasatch County, and flows southwesterly into the Du Cbesne river, a tributory of the Green. By reason of such application, they claim to have initiated a right to the use of three hundred second feet of water of such stream for irrigation purposes. Upon a protest filed by the respondents, the defendants below, who also filed applications for an appropriation of the same' waters, plaintiffs’ application was rejected and the respondents’ approved by the state engineer. The plaintiffs then brought this action in the District Court of the Fourth Judicial District against the defendants to adjudicate the questions involved.
¶2In their complaint it is alleged that on and prior to the 28th day iof August, 1905, there were three hundred second feet of unappropriated water of the stream, and that on that day, “at the hour of twenty minutes after nine o’clock in the forenoon,” they (the plaintiffs) “filed in the office of the state engineer of the State of Utah” their application in writing to appropriate three hundred second feet of water to' be used each year from January 1st to December 31st, to be diverted from the Green Biver system, Wasatch County, at a particularly described point on the East Bork of Lake fork of Green Biver. In such application the diverting works and channel were described, the purpose of such appropriation stated to be for irrigation, and the lands proposed toi be irrigated, consisting of a total area of 83,680 acres, described by reference to legal subdivisions. It is further alleged that the defendant Meagher on the 31st day of July, 1905, and the defendant'Jarvis on the 19th day of August, 1905, made applications to appropriate the same water by filing written applications with the state engineer, but that at the time of such filings “all of the said waters applied for” by them “the proposed point of diversion, and the lands proposed to be irrigated, were all a part of, and included in an Indian reservation within the state of Utah *215set apart exclusively for tbe use and occupation of tbe Indian wards of tbe federal government, wbicb was reserved from tbe public domain and under tbe' exclusive control of tbe United States of America., and that all matters and things pertaining to tbe appropriation of said water were done upon tbe Indian reservation so exclusively controlled as herein set forth, and that these plaintiffs filed tbe first application to appropriate tbe waters” of tbe stream in question “after tbe opening of said reservation.” . It is further alleged that tbe rights of the defendants Meagher and Jarvis, acquired by them by reason of their applications, were assigned to tbe defendant tbe Dry Gulch Irrigation Company; who in March, 1901, “protested tbe granting of these plaintiffs’ application,” wbicb was in June, 1907, rejected by tbe state engineer on tbe sole ground that their application “is in conflict with tbe prior applications” of tbe defendants Meagher and Jarvis. It is further alleged that tbe defendants have no right, title, or interest whatsoever in or to any portion of tbe water applied for by tbe plaintiffs; that they be required to set forth whatever rights- or interests are claimed by them; that such claims be adjudged to be unfounded and of no effect; and that plaintiffs’ rights and title in and to tbe use of tbe waters be determined, quieted, and confirmed. A general demurrer for want of facts was interposed to this complaint, wbicb was sustained by tbe trial court. Tbe plaintiffs stood on their complaint and declined to amend. Tbe action was thereupon dismissed. They appeal.
¶3Tbe only question presented for review is tbe ruling of tbe court sustaining tbe demurrer. The statute (Comp-. Laws 1907, see. 1288x et seq.), so far as neeesary here to notice, provides that, in order that one may acquire tbe right to tbe use of any unappropriated public water, be shall malee an application in writing to tbe state engineer, setting forth, among other things, tbe nature of tbe proposed use for wbicb tbe appropriation is intended, tbe quantity of water to be used, tbe time during wbicb it is to be used each year, tbe name of tbe stream or source where tbe water is to be diverted, tbe nature of tbe diverting works, tbe dimensions, *216grade, shape, and nature of the proposed diverting channel, and such other facts as will clearly define the full purpose of the proposed appropriation. It further provides that, “if the proposed use is for irrigation, the application shall show, in addition to the above required facts, the legal subdivisions of the land proposed to be irrigated, with the total area thereof, and the character of the soil.” It is further provided that, if the application is conformable to the requirements of the statute, the engineer shall receive and record it, and shall publish a notice of the application. At any time within thirty days after the completion of the publication, any person may file with the state engineer a written protest against the granting of the application. It then becomes the duty of the engineer to approve or reject the application. Either party aggrieved may then bring an action in the district court for the purpose of adjudicating the questions involved. It is further provided that, in his indorsement of approval of an application, the state engineer shall require that the actual construction work be commenced within six months from the date of such approval, and that it shall be completed within five years from such date. But the engineer may allow in some cases an extension of time to complete such work, or may limit the applicant to a less pexdod of time. It is further provided that, upon the completion of the work, proof shall be made and maps filed showing the nature and extent of the completed works, the stream or source, and place where the water, and the quantity thereof, is diverted, the character, grade, and dimensions of the diverting channel, and other things showing the diversion and appropriation of the wafer. Upon such proof a certificate of appropriation is then given the applicant, a copy of Avhieh is filed with the state engineer and one with the county recorder of the county where the water is diverted.
¶4It may be judicially noticed, and here stated, that Congress in 1902 ordered the unallotted lands of the Indian reservation referred to in the complaint to be
¶5But the serious question in the ease, and one not altogether free of doubt, is whether, to initiate a right in the use of unappropriated public water, it is esential, when the notice of intention to appropriate is given, or when, as required by the statute, a written application is made and filed with the state engineer, that the beneficial purpose or use for which the water is proposed to be appropriated shall be immediate and then existing, or whether the beneficial use may be contemplated or anticipated in the future. That is to say, when in an application filed to appropriate water in which the applicant is required, as by the statute provided, to set forth “the nature of the proposed use for which the appropriation is intended,” the quantity of water to be used, etc., and such other facts as will clearly define the full purpose of the proposed appropriation, and, if the proposed use is for irrigation, in addition thereto, “the lands pro*220posed to be irrigated, with the total area thereof,” the question is, in order to properly initiate a right to the use of "the water, whether “the lands proposed to be irrigated” must, when the application is made, be then subject to such a use and capable of being devoted to such a purpose, not necessarily by the applicant himself, but by some one. When the defendants made their applications to appropriate the Waters for the purpose of irrigation, no one could then lawfully enter upon, occupy, possess, cultivate, farm, or otherwise use “the lands proposed to be irrigated,” because they then were a part of, and included in, the reservation, and were then not open to entry, settlement, or disposition. Neither the applicants nor any one else could then lawfully use water on such lands. No present right permitting any one to make use of the beneficial purpose for which the proposed appropriation was made then existed. The inceptive right initiated by the defendants in and to the use of the water by the filing of their applications depended upon several contingencies: One, upon the actual opening of the reservation for settlement; another, upon the entering upon, or settlement of, or taking up of, some or all of the lands proposed to be irrigated by some one entitled to enter upon such lands, or to take them up, after the reservation was opened; and, still another, the agreement or consent of such persons to take and use the water on such lands, or otherwise to permit them to be irrigated therewith, or the water to be used thereon for the purposes of the proposed appropriation. Should any one of these contingencies fail, the proposed appropriation itself would prove abortive, because the application of the water'to the proposed beneficial purpose — ■ the absolute and indispensable essential to constitute a completed valid appropriation — could not be made in such ease. In this respect the appellants, however, do not stand on much better ground than do the respondents. The only difference between the parties is this: It is alleged that the respondents made applications to appropriate the water in question to irrigate lands then alleged to be a part of the reservation, the appellants to irrigate lands then a part of *221the public domain. In neither instance is it alleged that any portion of the lands proposed to be irrigated bad then been entered upon, or taken up*, or occupied, or possessed, or claimed, by any one; or that the lands were then, or since have become, subject to such a use. So far as anything is made to appear to the contrary, the lands proposed to be irrigated by the appellants were, when their application was filed, “at the hour of twenty minutes ' after nine o’clock in the forenoon” on the very day upon which the reservation was opened, and s.till are, a part of the public domain, unentered, unoccupied, unsettled, and unclaimed. - It is alleged, and we may judicially notice, when the reservation was opened and the unallotted
¶6So far, then, as made to appear by the complaint, it is shown that, when the applications to appropriate the water were filed, the beneficial use for which the water was proposed to be appropriated did not then exist, but was, by both parties, contemplated and anticipated in the future. That is, we may well assume that, when the applications were filed, both parties contemplated and anticipated1 that within the time fixed by the engineer for the construction of the works and the diversion of the water, and by the time such works were completed, the water diverted and conducted upon “the lands proposed to be irrigated,” such lands Would then be claimed, occupied, and possessed by some one entitled to claim and occupy them, and thus the water could, and would, be applied to the beneficial purpose of the proposed appropriation stated in the applications. May an application be made to appropriate water for a beneficial purpose so contemplated in the future? We confess that the question is open to debate, and is not free of doubt. We have, however, with some hesitancy, reached the conclusion that such an application may properly be made when it *222is made in good faith and with an actual bona fide
“The general purpose of an appropriation is to utilize the water in the arid regions, where the supply is limited, for the development and advancement of beneficial industries. In many localities where the water is difficult of diversion, and the expense considerable in conducting it to the place of use, if individual landholders, or even an aggregation of them, were required to make the appropriation for use upon their own possession, these general purposes would be entirely defeated simply for the reason that such holders could not bear the burden of making the appropriation. In such eases, other persons possessing capital are often willing to make the diversion for the benefit of those who have use for the water, but, unless they may contemplate a use which may be applied by the landowner to his possessions, they could not even initiate the appropriation until they had possessed themselves of lands in proportion to the amount of water it is desired to appropriate; so *223that if the user must be the appropriator, and the appropriator the landholder, the arid regions in many places would remain arid, whereas otherwise they could be made to teem with fertility. No sufficient reason has been suggested why the contemplated use may not be for and upon the possessions of a person other than the appropriator. The authorities we have seem to support the rule that it can be, and we believe it is, correct upon principle. We take it, therefore, that the bona fide intention which is required of the appropriator to apply the water to some useful purpose may comprehend a use to be made by or through another person, and upon lands and possessions other than those of the appropriator. Thus the appropriator is enabled to complete and finally establish his appropriation through the agency of the user.”
¶7Of course, we are not unmindful that wbat was said by these writers and courts was with respect to appropriations not regulated by statute. But we think the filing of a written application with the state engineer, as required by the statute, is but declaring, or the giving of a notice of, an intention to appropriate unappropriated public water. The final step, and the most essential element, to constitute a completed valid appropriation of water, is the application of it to a beneficial purpose. Whatever else is required to be or is done, until the actual application of the water is made for a beneficial purpose, no valid appropriation has been effected. This was so before the statute, and it is still so under the statute. The filing of the application with the state engineer, as required by the statute, does not establish an appropriation of water. It but takes
¶8We are of the opinion that, upon the face of the complaint, it is not made to appear that the engineer wrongfully or erroneously approved the defendant’s applications, which were prior in time. However, should we be in error in holding that an inceptive right in and to the use of unappropriated public water upon or within a reservation can be initiated or acquired after the issuing of the proclamation, but before the reservation was actually opened and the lands subject to entry, settlement, and disposition, a contrary holding would not materially aid the cause of the appellants for the reasons hereinbefore suggested. And since the appellants, if entitled to recover, must do so> upon
¶9We are therefore of the opinion that the judgment of the court below ought to be, and it therefore is, affirmed, with costs. Such is the order.
