¶1delivered the opinion of the court..
¶2This suit was instituted by Perry J. Moore to have determined the relative rights of several claimants to the use of the waters of the East Fork of Little Elk Creek, in Meagher county. Defendant Helen Pump was denied any right by virtue of a certain appropriation made by her predecessor in 1892, and it is *544from the decree in so far as it denies this right, and from an order refusing a new trial that these appeals are prosecuted.
¶3The trial court found that in 1892, F. Miller made an appropriation of fifty miner’s inches for the irrigation of a desert claim then owned by him; that he used the water upon the land continuously until his death in 1903; that his widow, executrix of his last will, did not thereafter exercise such right at all; that in 1911 defendant Pump succeeded to the land and its appurtenances, and that she did not use the water nor assert any claim to the right up to the time she appeared in this action; that the ditch constructed in 1892 was suffered to become out of repair and to become overgrown and filled until it was practically indistinguishable upon the ground, was incapable of carrying water and gave no notice of its existence. Finding No. 15 is as follows: “That the said defendant Helen Pump did not show, or attempt to show, either by herself or her predecessors in interest, any use of the waters of Little Elk Creek through said 1892 ditch, or the exercise of act of dominion or ownership over the said ditch or water right by said Eoy O. Sherman, but it does appear that neither the said Mrs. Miller, while managing said F. Miller estate, nor the said defendant Helen Pump, as successor in interest of said estate, had any conscious intent to abandon said ditch and water right, but, on the contrary, if they had any conscious thought on the subject, in their own minds did not intend to abandon the same, although said intention was not communicated, in any manner, to the public, and the said' Mrs. F. Miller explained her failure to use the said water or ditch as being due to the amount of work involved in the management of said Miller estate property. ’ ’
¶4In what is denominated conclusion of law “E,” the court declared that by failing “to so use any of said waters or to do any work upon said ditch and water right, and permitting, without objection or actual notice, third parties to initiate rights and place lands under cultivation and to cultivate the same for years, under the assumption that no such right existed and that the said right of 1888 was the only right claimed by said de*545fendant as appurtenant to her lands acquired from said F. Miller, and by a course of conduct, which would, in the absence of her statement to the contrary, show a clear intent and purpose to abandon said right and ditch, if any she had, the said defendant is declared to have failed to establish any right in and to the waters of said Little Elk Creek by reason of said ditch constructed in the year 1892, and to have forfeited any right which may have existed at the time of the death of said F. Miller, and to be estopped from asserting any such right as against the answering defendant Roy O. Sherman.” This conclusion presents the court’s explanation of the decree, in so far as it denied to this appellant any right based upon the Miller appropriation of 1892.

¶7The court found that neither Mrs. Pump nor her predecessor, Mrs. Miller, intended to abandon the 1892 right, but, on the contrary, so far as they had any conscious intent, it was not to abandon either the ditch or water right. In the absence of any intention to abandon there could not have been an abandonment.

¶9In Featherman v. Hennessy, 42 Mont. 535, 113 Pac. 751, the court said: “Mere lapse of time during which there is nonuser is not sufficient. The circumstances must be such as to justify an inference of intention to abandon; in other words, to leave the property to be taken by any other person who chooses to do so.”
¶10There was not any abandonment of the 1892 right, and the decree cannot be justified upon that theory.
¶112. Estoppel: There is not any plea of estoppel, but the pleadings were treated as amended to conform to the proof, and we are therefore to search the testimony for the facts which estop this appellant, if any such are disclosed by the record.
¶12*547Either Mrs. Pump or her predecessor, Mrs. Miller, by her conduct might be estopped to say that she did not intend to
¶13Defendant Sherman is the only one who is benefited by the decree in its present form; the only one to be injured by a recognition of the 1892 Miller right, and the only one contesting appellant’s claim to that right; so that, if appellant is estopped to claim the right or if she or her predecessor is estopped to say she did not intend to abandon it, the elements constituting the estoppel must be found in some representations made or some position assumed, upon which defendant Sherman, having the right so to do, in good faith relied and from which inequitable consequences must follow if the representations be repudiated or the position be changed. (10 Rul. Case Law, 689.)
¶14Constructive fraud underlies every equitable estoppel; “that is, the person estopped is considered as having by his admissions, declarations or conduct misled another to his prejudice, so that it would work a fraud to allow the true state of facts to be proved.” (10 Rul. Case Law, 691.) The Sherman appropriations were made in 1907, when the Miller property was in charge of Mrs. Miller. The record contains all the evidence produced relative to the 1892 right, but there is not a suggestion that Mrs. Miller, this appellant or anyone else said or did *548anything with reference to that right. Although Sherman testified at length with reference to the physical condition of the 1892 ditch, he did not intimate that in making his appropriations he relied upon an abandonment of the 1892 Miller appropriation or that he even considered the probability of that right being asserted or abandoned. So far as disclosed by this record, he was not misled at all. There is not even a bare scintilla of evidence that either Mrs. Miller or Mrs. Pump knew anything of Sherman’s intentions, or of his appropriations, until long after they were made. The only inference to be drawn

¶17*549Upon the findings made, the trial court should have awarded appellant fifty miner’s inches or one and one-fourth cubic feet per second of time. A new trial is unnecessary and the order refusing it will be affirmed. The cause is remanded to the district court with directions to modify the decree so as to award to appellant fifty miner’s inches or one and one-fourth'cubic feet per second of time of the waters of the East Fork of Little Elk Creek, and when thus modified, the decree will stand affirmed. The appellant will recover her costs of appeal.
