delivered the opinion of the Court.
After the opinion heretofore rendered in this case (23 Mont. 65, 57 Pac. 557), the court of its own motion granted a rehearing. Additional briefs and oral arguments have been filed and made, and we are satisfied upon further consideration that the conclusion announced in the former opinion is erroneous.
The ultimate question presented for decision is whether a certain water right is appurtenant to a certain parcel of land. As preliminary to the determination of this question, it is necessary to investigate the nature of a ‘ ‘water right, ’ ’ how title to the same may be acquired, the character of its ownership, and its relation to other real property.
It may be remarked, obiter, that the common-law doctrine of riparian rights assured to each riparian owner the right to the reasonable use, without substantial dimunition in quantity or deterioration in quality to the detriment of other riparian proprietors, of the water of a stream flowing by or over his land. The doctrine of “prior appropriation” confers upon a riparian owner, or one having title to a water right by grant from him, the right to a use of the water of a stream which would be unreasonable at the common law, and to this extent the doctrine of prior appropriation may be said to have abrogated the common-law rule.
A legal appropriator of water may change the place of its use, and may use the water for other purposes than that for which it was originally appropriated. (Section 1882 of the Civil Code; Woolman v. Garringer,
For the purpose of illustrating the practical application of the foregoing principles, we shall consider a few cases of common occurrence:
(a) A. has absolute title in fee to riparian land. Under the statutes of Montana he is clothed with the right, by compliance with the provisions of the statute, to appropriate a water right, subject, of course, to the vested rights of prior appropriators. Now, being the owner of riparian land, he can, as has been shown, legally exercise this privilege on his own land; and, when he has perfected such inchoate right by fulfilling the requirements of the statute, the legal title to such water right becomes vested in him, — not, however, by reason of any common-law riparian rights as owner of the soil, but by reason of statutory grant. Title to the land and title to the water right are in A.’s case two distinct things, each derived from a separate source. The question now presents itself: Is the water right thus acquired by A. an appurtenance to the land of A. upon which it is used? We have already
(b) B. owns nonriparian land. He cannot, therefore, take up a water right on his own land. He has, however, by statutory grant, the privilege of appropriating water upon the public domain or upon land owned by the state; if, however, there is no such land of which he can avail himself for the
(c) C. has possessory right to government riparian land. In this case C., of course, has the privilege, by statutory grant, of appropriating a water right for the land which he
(d) D. has possessory right to government nonriparian land. If D. lawfully acquires a water right upon the public domain, and conducts water by a ditch over the public domain to the land which he occupies, and uses the same thereon, it is clear, from the results reached in the foregoing discussion, that such water right and ditch will not become an appurtenance to the land occupied by D. until he obtains title thereto from the government, or conveys his water right and ditch to the owner of the land.
With the foregoing established legal principles kept in mind, let us proceed to the consideration of the case at bar. At the very outset of the investigation of the record in this case the language of the Court in Wood v. Lowney,
The record does not clearly disclose, but upon the oral argument counsel conceded, that Cosins appropriated the water from the public domain, and that he was then in possession of a certain parcel of nonriparian land under a contract with its owner; what the contract was does not appear; he was, however, admittedly in rightful possession of the nonriparian land, the title to which was in another. His water right was legally acquired by an appropriation thereof on the public domain; he conducted the water, by means of a ditch over the public
In the case at bar the defendant does not assert or pretend that , there ever was any conveyance by Cosins of his water right to the Northern Pacific Railway Company, the owner of the land; and, since an easement can only become legally attached to land by unity of title in the same person to both the dominant, tenement and the easement claimed, it is apparent that the Northern Pacific Railway Company could not grant or convey the water right to the defendant as an appurtenance to its land, for the reason that it has never owned the same, and therefore the right and ditch have never been legally attached as appurtenant to the land now occupied by the defend
The common-law rule that an easement acquired by a tenant as an appurtenance to the land inures to the benefit of the landlord upon the expiry of the tenancy (Dempsey v. Kipp,
The contention that Cosins abandoned his water right by executing a mortgage thereof cannot be successfully urged in this case. (Middle Creek Ditch Co. v. Henry,
The judgment is reversed, and the cause remanded
Reversed and remanded.
