delivered the opinion of the court:
This is a special proceeding under the statute to obtain a decree adjudicating to the petitioner a priority of right to the use of water for irrigation.
In 1903 appellee, as petitioner below, filed its statement with the clerk of the district court of Fremont county claiming to have made an appropriation of water for irrigation. In 1904 it filed in the district court of that county its petition in the pending proceeding alleging, inter alia, that after the rendition of a final decree of that court which, in appropriate proceedings under our irrigation acts, established the relative priority of rights to the use of water for irrigation in water district No. 12, petitioner made an appropriation of water for irrigation which in no way interfered or conflicted with those adjudicated by the former decree, and prayed for a decree establishing its rights in accordance with the statute in such cases provided.
The alleged right pertains to artificial waters which, by petitioner’s exertions and those of its grantors, have been.produced and added to the natural flow of the stream as the result of the drainage of various mines in the Cripple Creek mining district, and which, after they reached the bed of the stream, were by it appropriated.
This proceeding was conducted according to the statute. Some of the respondents appeared and denied petitioner’s claims. A large volume of evidence was taken, and the court found in favor of petitioner and rendered a decree accordingly. Therefrom certain of the respondents have brought the case here by appeal.
The court specifically found from the mass of evidence: That the petitioner was not a party to the former decree; and that the waters in controversy *131were, by its exertions, artificially produced as tbe result of draining mines, and by a tunnel discharged into tbe natural stream called Oil creek, or Four-Mile creek, wbicb is tbe appellants ’ source of supply, all of whose- natural waters bad previously been appropriated by them and others. Tbe court found that such waters were subject to appropriation, and bad been first appropriated by the petitioner, after having been produced and raised to tbe surface, all of wbicb bad thus been contributed to the- stream since tbe former statutory decree was rendered, and formed no part of its natural flow, and never would have come into tbe stream in any way bad it not been for tbe efforts of petitioner, except to tbe extent of four cubic feet of water per second of time, wbicb is tbe amount of water wbicb directly or indirectly, as tbe court found from the evidence, would naturally have reached tbe bed of tbe stream bad not tbe mines been drained. Since four cubic feet per second would have naturally found its way into tbe stream, bad not tbe mines been drained, and since the- court further found that of tbe volume of additional water to wbicb petitioner was entitled as it passed from tbe portal of tbe tunnel, ten per cent, thereof would be lost from evaporation, seepage, and other natural causes between tbe portal and tbe headgate of its ditch, petitioner was allowed to withdraw from tbe stream only ninety per cent, of all waters discharged from tbe tunnel, in excess of four cubic feet per second of time.
Upon such findings tbe court, in virtue of its contribution of artificial water to tbe stream, and tbe fact that in October, 1895, it made appropriation thereof before tbe rights of any other person attached, decreed that petitioner has tbe exclusive-right to. use and collect tbe same at tbe portal of tbe tunnel, and to cause such waters thus collected to *132flow down and into the channel of Four-Mile creek to the headgate of its ditch without interference hy other persons, and to withdraw at the headgate of its ditch the ninety per cent, mentioned.
The specific objections -which the appellants make to this decree are thus stated: (1) That the water flowing through the drainage tunnel and adjudicated to appellee was not artificial water, but a part of the natural flow of Four-Mile creek which had theretofore been appropriated by appellants and others using water from the creek, and which had been decreed to them in the former statutory proceeding; (2) that, if it was not properly a part of the natural flow of the creek, then it was water which had been produced in the earth by means of artificial work, and, as such, may not be decreed in a proceeding of this sort under the so-called irrigation acts; (3) but if this is not so, and if it is not part of the natural flow of the stream, then it is water covered by our drainage statute, and declared thereby to be subject to be taken and used the same as the water of a natural stream, and therefore subject to appropriation, and cannot be acquired, as attempted here, as private property; (4) that if this so-called tunnel water is subject to appropriation, the evidence shows affirmatively that the appellee had never made any beneficial application of the same before the filing of the petition, and therefore cannot have a decree therefor as a. perfected appropriation at this time.
The evidence in some particulars is conflicting, in others preponderates in favor of the petitioner. At all events, the trial judge, who saw the witnesses and heard them testify, found in its favor, and with such findings we cannot interfere. We may add, however, that the parties concede that in its natural state this water which has been drained from -the *133mines was originally inclosed in á basin whose- walls are granite which is practically impervious to water; and the evidence tends to show, and the court found, and the parties practically concede, as we understand, that, with the exception of such quantities as overflowed from the basin at low places in the rim and through fissures in the granite, none of it reached the bed of the natural streams in the adjacent valleys. The estimate of the court was that four cubic feet per second of time would thus have reached the streams had not these mining operations been prosecuted.
The court found, then, on evidence somewhat conflicting, that when the former statutory decree was rendered, by which certain awards were made to appellants, none of this water, with the exception of the four cubic feet per second of time, was allotted to the appellants, for none of it, save the amount specified, could or would have reached the stream from which they obtained their supply.
It is not necessary to rest the judgment solely, or at all, on petitioner’s contract right with the owners of the mines which purported to grant to it, as against all others, the right to collect and take this water at the portal of the tunnel; for the court found that the petitioner not only conducted this artificial water into the natural stream with the intention there tó appropriate it, but also there actually made the first appropriation thereof after it reached the same. Our statute has made such water the subject of appropriation. — 2 Mills’ Ann. Stats., §3177. We have held that such contributions to a natural stream belong to the one who made them. — P. V. Irr. Co. v. Buckers, etc., Co., 25 Colo. 77. Certainly the fact that petitioner has contributed this water to the stream does not tend to weaken its right thereto as a first appropriator.
*134The further contention of appellants, that the evidence affirmatively shows that at the time of the filing of its petition the petitioner had not made a successful appropriation of the water to a beneficial use, is not tenable. The court, upon conflicting' evidence', has found against their contention.
It appears that a number of tunnels were run for the purpose of draining the mines in the Cripple Creek district, and that the El Paso drainage tunnel, from which the water now issues, was the last of several from which the petitioner collected and conducted it into the natural stream. The evidence shows that in time a drainage tunnel exhausts the supply of water from the earth above, and later it becomes necessary to drive other tunnels at lower levels, and as they succeed in draining the ground above, still others are run farther down the mountain side. Several years before the filing of this petition, the appellee had built its ditches and reservoirs and attempted to utilize the water of the earlier drainage. tunnels, and had enjoyed the use thereof except at times when interference therewith was made by appellants and other appropriators. The inception of appellee’s right was not at the time of the construction of the El Paso drainage tunnel, but, by reason of the facts to which we have just alluded, relates back to the time at which it sought to utilize water from the earlier and higher tunnels before the petition was filed, or the El Paso tunnel was run.
The district court seems to have given much thought and attention to the evidence produced before it, and as its findings are supported thereby, and as we' are of’ opinion that the rights in controversy can be determined in this proceeding, the' judgment and decree are affirmed. Affirmed.
