The defendants appeal from a judgment in
favor of plaintiff.
The object of plaintiff’s suit was to enjoin the defendants from enlarging Old Live Oak Slough and from constructing or maintaining a certain proposed ditch, and from doing any other act or thing whereby any of the waters falling upon the lands northeasterly of a certain alleged ridge, some six miles northerly of plaintiff’s lands, might be precipitated, or the flow thereof accelerated, to or upon the plaintiff’s lands. He also asks for a mandatory injunction requiring defendants to fill up so much of said ditch as had been dug before the suit was begun.
The plaintiff’s lands consist of one hundred and eighty acres. He alleges that about six miles north thereof there is a high ridge of ground which, unless interfered with by the defendants, does and will effectually prevent the water falling upon the land northerly and easterly thereof from flowing down to and upon his own land. He further alleges *443that south of said ridge there extends from said ridge, in a southerly direction, for a part of the distance to his land a slough known as Old Live Oak Slough, with, which is connected an artificial ditch extending therefrom to and through his land, by means whereof the waters of the slough are drained and carried away to lower lands. With respect to the acts of the defendants complained of, he alleges that they are engaged in digging a ditch through said ridge of land, which will cut through the same and drain the waters falling upon the lands northerly and easterly thereof into the slough and through the ditch leading therefrom to and upon the lands of the plaintiff, and that they also threaten to, and, unless restrained, will deepen, widen, and extend the slough from the point where the defendants’ proposed ditch enters the same in a northeasterly direction, thereby bringing into said slough and down to and upon the lands of the plaintiff a vast body of water which falls and accumulates upon lands northeasterly of section 8, in which section said ridge is situated, which water would not at all reach plaintiff’s lands without the doing of said threatened work by the defendants, and that by reason of said additional water coming into said ditch crossing plaintiff’s lands it will be caused to overflow plaintiff’s lands and render them unfit for cultivation, to his great damage.
The answer to the complaint consisted of denials and affirmative defenses. The court on motion of the plaintiff struck out the affirmative defenses and a part of the denials and thereupon it sustained a general demurrer to the answer without leave to amend, and rendered the judgment appealed from. This judgment enjoins the defendants from digging the proposed new ditch or from deepening, widening, or extending the slough or doing any other act or thing which will cause the waters from the lands northerly and northeasterly of said ridge to flow down to and upon the plaintiff’s lands. It also commands the defendants to refill with earth the lower thirty feet of the ditch which they have dug northerly from Old Live Oak Slough. The defendants, in support of their appeal urge that the court erred in striking out the portions of the answers and in sustaining the demurrer to the remainder thereof.
The gist of the threatened injury alleged in the complaint is the making of the new ditch and the alteration of the slough *444in such a manner that the water falling on the land north of the alleged ridge, and which did not before reach plaintiff’s lands, will be -carried to and upon said lands through said proposed ditch across the ridge. Every landowner must bear the burden of receiving upon his land the surface water naturally falling upon land above it and naturally flowing to it therefrom, and he has the corresponding right to have the surface water naturally falling upon his land or naturally coming upon it, flow freely therefrom upon the lower land adjoining, as it would flow under natural conditions. From these rights and burdens, the principle follows that he has a lawful right to complain of others, who, by interfering with natural conditions, cause such surface water to be discharged in greater quantity or in a different manner upon his land, than would occur under natural conditions. This is the settled law of this state. (Conniff v. San Francisco, 67 Cal. 49, [7 Pac. 41]; Ogburn v. Connor, 46 Cal. 351, [13 Am. Rep. 213]; McDaniel v. Cummings, 83 Cal. 519, [8 L. R. A. 575, 23 Pac. 795]; Gray v. McWilliams, 98 Cal. 162, [35 Am. St. Rep. 163, 21 L. R. A. 593, 32 Pac. 976]; Stanford v. Sam Francisco, 111 Cal. 198, [43 Pac. 605]; Hicks v. Drew, 117 Cal. 305, [49 Pac. 189] ; Rudel v. Los Angeles Co., 118 Cal. 288, [50 Pac. 400]; Cushing v. Pires, 124 Cal. 665, [57 Pac. 572]; Cloverdale v. Smith, 128 Cal. 233, [60 Pac. 851] ; Larrabee v. Cloverdale, 131 Cal. 99, [93 Pac. 143]; Wood v. Moulton, 146 Cal. 317, [80 Pac. 92].)
The fifth paragraph of the answer was stricken out. In it the defendants deny that they are now or ever have been engaged in digging a ditch through said ridge of land or that any ditch as planned or now in course of construction by them will cut through said ridge. These allegations merely refer to the construction of a ditch cutting through the ridge. This act is not the essential part of plaintiff’s action. It is the making of excavations which will so alter natural conditions that additional surface water will be discharged upon plaintiff’s lands that constitutes the ground of his complaint. This paragraph, however, also contains the following: “Defendants deny that any ditch or canal now being dug or constructed by them or which they have, previous to the commencement of this action, been engaged in digging and constructing, will connect the territory lying north of said alleged ridge with *445said Old Live Oak Slough, or that it will effectually drain all or any water falling upon said lands to the north and northeast of said alleged ridge into said slough, and through said artificial ditch or canal mentioned in plaintiff’s complaint to and upon the lands of plaintiff or any part thereof in any greater volume or in any different manner than that in which they have heretofore since the year 1896, been accustomed to flow and drain.” It appears from other allegations in the answer which were also stricken out, that in the year 1896 the ditch running through the plaintiff’s lands was constructed by the defendants for the purpose of draining the waters from Old Live Oak Slough, and that it has ever since that time been maintained for that purpose. This explains the allusion to the accustomed flow of water since 1896, in the part of the answer above quoted. The effect of this denial is to raise an issue upon the allegations of the complaint that the waters falling upon lands northerly and easterly of the alleged ridge will be carried upon the plaintiff’s lands, by reason of the alleged excavations of the defendants, in greater quantities than would occur under natural conditions. This is the gist of the plaintiff’s cause of action and without it he would not be entitled to the judgment he obtained. The denial raised a material issue upon which the defendants were entitled to a trial. For this reason the court erred in striking out this portion of the answer.
In paragraph VI of the answer there is an allegation that none of the work as planned or in process of construction by the defendants, when completed, will cause any additional surface water to flow through said slough and ditch to the injury of the plaintiff in any manner or at all. This is but a repetition of the matter above quoted from paragraph V and it is perhaps more in the nature of a conclusion than a statement of fact. It might well have been stricken out as .unnecessary because it is, at most, but a repetition of a previous denial.
Other allegations, in connection with the part of the answer which was stricken out, were to the effect that a drainage district was formed in the year 1895 for the purpose of draining lands in the vicinity of plaintiff’s lands; that this drainage district, under proper proceedings for that purpose, constructed the ditch over the plaintiff’s land for the purpose of *446draining the waters of said slough, and that the district purchased and now owns a right of way over the plaintiffs lands for that purpose. These matters were wholly immaterial to the case. Granting that the drainage district had procured a right of way to construct the ditch now existing across the plaintiffs lands, it would not at all follow that it, or any other person, would have the right to cause additional surface water to flow therein sufficient to make it overflow its banks and injure the plaintiffs lands. It is not alleged that said district has ever obtained, or now has, the right to cause such overflow. These matters were properly stricken from the answer.
The order striking out paragraph five of the answer and the giving of judgment for the plaintiff, under these circumstances, deprived the defendants of the substantial right of having a trial upon the material issue of fact which they had tendered, and for that reason the judgment is erroneous.
The judgment is reversed.
