delivered the opinion of the court.
This cause is before this court upon appeals by the plaintiff from a decree in favor of defendants and an order denying his motion for a new trial. The controversy involves the right to the use of the water in Blind or Ryan lake, situated in Powell county. Dempsey creek has its source on the eastern slope of a range of mountains extending north and south, and flows through a canyon toward the southeast into the valley, and thence into Deer Lodge river. Blind lake is situated on the public domain, in a depression high up on the eastern slope of the same range, some distance to the southwest. To the north of the lake is a high ridge or backbone, extending several hundred feet to the east beyond the eastern rim of the lake, terminating in a point from which there is a sharp descent to the east, northeast, and south. To the south is another ridge which extends further to the east. Between these, and toward the east and north, extends a canyon, the natural surface of which slopes from the eastern rim of the lake for a distance of 2,725 feet at an average angle or grade of twelve feet to the hundred, and thence, at an angle of about sixteen feet to the hundred, 2,400 feet to the level of Dempsey creek. To the west the country is mountainous. The lake is fed by streams flowing into it from this direction and by flood water from melting snow. Over its eastern rim there is a small flow of water, estimated at from fifteen to forty inches, which follows a well-defined natural channel in the general direction of Dempsey creek. As it descends the slope, the flow gradually decreases in volume until it disappears entirely at or near a point 1,500 feet from the lake, or 3,625 feet from the channel of the creek.
Defendants’ answer puts in issue the material allegations of the complaint, and alleges that plaintiff’s right was adjudicated by the decree of 1902, and that he is estopped by it to set up the claim now made. The court found in favor of defendants: (1) That the decree of 1902 finally adjudicated the rights of all the parties to the use of the water flowing in Dempsey creek; (2) that the right of plaintiff therein was thereby adjudicated to be inferior to that of all the defendants; (3) that plaintiff’s appropriation made in 1902 was of water which is tributary to Dempsey creek; (4) that the normal flow from the lake, when not obstructed by the works and dam erected by plaintiff, reaches the creek and becomes a part of it “by means of open, underground seepage and percolation”; and (5) that after the water leaves the lake it flows “over and down a steep and precipitous route in the direction of and on the watershed of said Dempsey creek” until it enters it and becomes a part of the water therein.
The contention is that the evidence is insufficient to justify the findings. It will be noted that the term “open,” used in connection with the phrase “underground seepage and percolation,” renders finding 4 unintelligible. To this term as used here must be assigned the meaning “plain, in sight, exposed to view.” Water seeping or percolating underground cannot, in the very nature of things, be in plain sight or exposed to view. Doubtless
As heretofore stated, the question as to whether the lake is tributary to the creek was not directly involved in the action. The parties were not aware of its existence except by hearsay. Whether, therefore, the plaintiff is estopped by the decree to assert his present claim, depends upon the facts as they actually exist, and not upon a mere construction of it implied by the judgments in the contempt proceedings. Furthermore, so far as the record shows, the violation complained of by the defendants in each instance was an interference with the natural flow of the water in the creek, by which they suffered deprivation. It does not appear that the right of plaintiff to appropriate the overflow of the lake or to use the lake as a reservoir for storage purposes was considered or determined. The judgments are not pleaded. For these reasons they are not to be looked to as aiding the decree or as determinative to any extent of plaintiff’s rights. If in fact the lake is not tributary to the creek, the existence of the decree does not make it so, and, though it be conceded that in the contempt proceedings the court undertook to determine the rights now asserted by plaintiff, such [1] determination cannot be given any conclusive effect. Substantive property rights cannot be adjudicated in this summary way. For this purpose the right asserted must be put in issue
The contention of plaintiff, therefore, presents the question: Does the evidence sustain the ultimate finding that the lake is [2] tributary to the creek? The burden was necessarily upon the plaintiff to establish his right to intercept and appropriate the natural overflow from the lake, for if this overflow, however small in volume, reaches the creek by reasonably ascertainable channels, it is one of its sources of supply.
The evidence introduced by plaintiff tended to show that there is a complete disappearance of it at a point 1,500 feet distant [3] from the lake, and that beyond that point there is no surface channel, nor any indication upon the surface of an underground way or channel in the direction of the creek. Prima facie, therefore, it was thus made to appear that the overflow does not find its way into the creek. The lake being upon the public domain, the plaintiff was prima facie entitled to make use of it and to intercept the overflow as he did, provided that in doing so he did not interfere with the use by defendants of the natural flow in the creek. The burden was then cast upon the defendants to show that, if uninterrupted, the flow finds its way into the creek by a defined channel either upon the surface or underground, and that plaintiff’s appropriation of it diminishes the volume of water flowing in the creek. This they undertook to establish by showing the character of the debris filling the canyon, and the configuration of the adjacent country. It does not appear, however, from the statement of any witness, that there is any natural surface channel beyond the point of disappearance. While it does appear that the debris in the canyon is perhaps pervious to water, there wqs not any attempt to show that this is the fact, nor that the vegetation on the surface prior to plaintiff’s diversion indicated a defined watercourse beneath, nor that there
It has been settled by a long line of decisions that percolating [4] water is not governed by the same rules that are applied to running streams. “The secret, changeable, and uncontrollable character of underground water in its operations is so diverse and uncertain that we cannot well subject it to the regulations of law, nor build upon it a system of rules, as is done in the case of surface streams. Their nature is defined, and their progress over the surface may be seen and known and is uniform. They are not in the earth and a part of it, and no secret influences move them; but they assume a distinct character from that of the earth, and become subject to a certain law — the great law of gravitation. There is, then, no difficulty in recognizing a right to the use of water flowing in a stream as private property, and regulating that use by settled principles of law. We think the
Subsurface water flowing in defined channels reasonably [5] ascertainable is subject to the same rules as water flowing in surface streams; but there is no presumption that any sub
The condition in which this case has reached this court, however, does not require the announcement of any definite rule. It does not appear that the lake water reaches the creek by any [7] means. As we have said, the conclusion reached by the trial court that it does was based upon speculation rather than upon substantive evidence; hence the findings may not be allowed to stand. It is apparent from the disclosures in the record that there are many additional facts readily obtainable, the production of which would enable the trial court to reach a conclusion upon a full disclosure of the facts as they may be made to appear. For this reason, and because of the importance of the legal questions which may require determination, we think it proper to direct a new trial, at which the parties may produce such additional evidence if they desire to do so. We observe, too, that, though the plaintiff may be defeated in his claim of right to appropriate the natural overflow from the lake, it may be possible for him so to present the facts touching the use of the stored water that the court may decree him a substantial right in that behalf. This feature of the case seems to have been lost sight of by the court when it made its findings..
The decree and order are reversed, and the cause is remanded for a new trial.
Reversed and remanded.
