delivered the opinion of the court:
Plaintiffs below (appellees here), by their complaint, alleged that they were the owners of certain water rights in adjudicated priority No. 8 of the waters of Kannah creek, water district No. 42, Mesa, county, Colorado; that defendants below (appellants here) were the owners of adjudicated priority No. 5 of the waters of said Kannah creek; that both of said priorities took their water from Kannah creek through the Brown and Campion ditch; that the headgates of the laterals of plaintiffs are above the headgates of the laterals of defendants on the line of said Brown and Campion ditch; that pursuant to section 3, page 236, of the Laws of 1899 (3 Mills’ Rev. Stats., § 2273c), and by a strict compliance with all the requirements of said section, the owners of adjudicated priority No. 2 of the waters of Kannah creek loaned to plaintiffs, for a limited time, thirty inches of water of said stream of adjudicated-priority No. 2, to be used by the plaintiffs in saving their crops and orchards; that, for the purpose of utilizing the said thirty inches of water so loaned to them by *249the owners of adjudicated priority No. 2, the said water was taken out of the creek through the head-gate of the Brown and Campion ditch, down and through the said ditch and along, hy and adjacent to the headgate and lateral through which the defendants divert water for the irrigation of their lands; that defendants, well knowing the facts relating to the loan of the said thirty inches of water to plaintiffs, wrongfully, unlawfully and forcibly, without consent of plaintiffs, took and diverted the said thirty inches of water into the laterals of said defendants and- used said water for the irrigation of their lands and refused to close the headgate on their lateral or allow plaintiffs or any one else to do so, thereby wrongfully, unlawfully and forcibly depriving plaintiffs of the use of said water to the irreparable damage and injury of plaintiffs, and that defendants, unless restrained, threaten to and will continue so to do.
A perpetual injunction was prayed.
Defendants demurred to the complaint upon the grounds that it did not state facts sufficient to constitute a cause of action.
The demurrer was overruled, and defendants electing to stand upon the demurrer, judgment was rendered making the temporary injunction, theretofore granted, permanent.
Error is assigned upon overruling the demurrer and entry of judgment.
It is the contention of appellants that section 3 of the act of 1899, Session Laws 1899, page 236 (3 Mills’ [Rev.] Stats., § 2273c), is unconstitutional as being in conflict with § 6, article 16, Colorado constitution.
Fort Lyon Canal Co. v. Chew, 33 Colo. 392, disposes of this* contention adversely to appellants, by placing a construction upon the statute in ques*250tion, which, permits an exchange- or loan of water under circumstances and conditions which do not injuriously affect the vested rights of other appropriated. At page 402 Mr. Justice Campbell said:
“Sections 1 and 2 of the 'act prohibit the change in point of diversion until the party desiring to make the same has obtained an adjudication of the court that it can lawfully be accomplished without impairing the vested rights of others; that is to say, the-right cannot be exercised at all until after a decree therefor has been obtained that vested rights are not impaired. Section 3 seems to recognize a temporary exchange or loan of water without first obtaining a decree. The right, however, in the latter case, if it exist at all, as we have already held, is just as much subject to the qualification that the vested rights of others are not to be impaired as in the case of an attempted permanent change of the point of diversion. And when it has been made, though it may be effected without first obtaining a decree therefor, it is incumbent upon the party asserting rights under the loan or exchange, when challenged by an action in court, affirmatively to show that it can be exercised without interfering with, or impairing, the vested rights of others.”
And again, at page 404:
“If, as a matter of fact, these loans were made under conditions and in circumstances' which permit of exchanges and loans of water, it is only right and proper that the burden of establishing the same be put upon the parties thereto. That this is the rule that should prevail seems only fair and just. * * *
“Such being the law of this state, when such exchanges or loans are made, or attempted to be made, they ought not to be permitted, if at all, until the parties seeking their benefits have clearly established that the alleged qualified right has been exer*251cised in snch a way, and at such times and in such circumstances, that the vested rights of others are not injured.”
There is no allegation in the complaint, nor any averment to supply the want of such allegation, to the effect, that the alleged right-of the owners of priority No. 2 to loan plaintiffs thirty inches of water of such priority,'or that the alleged right of plaintiffs to borrow and use such water for the purposes set forth in the complaint, have been or can be exercised in such way as to not injuriously affect the vested rights of defendants in priority No. 5.
Under the above authority, the burden of establishing such facts resting upon plaintiffs, the complaint should make apt averments in that behalf.
The complaint being deficient in this regard, the court erred in overruling the demurrer of de-' fendants, for which error the judgment must be reversed. Reversed.
