Defendant’s railway was constructed in 1869. At the point in question it crosses a slough, or swale, through which the surface water from several hundred acres of land lying on the north side of the track found its way to the Nishnabotna river. In the original construction of the railway, this slough was spanned by a trestle, which permitted the passage through defendant’s right of way of all the water which came upon it from the north through'the slough. The track was maintained in this condition until 1879, when defendant filled the space covered by the trestle, making a continuous embankment which prevented the passage of the water. It also constructed a ditch on the north side of its track, through which it sought to conduct the water to the river. This ditch was not of sufficient capacity, however, to carry all of the water which came through the slough, and it caused a portion of the lands lying on the north side of the track to be overflowed. It was also found that the abutment of defendant’s bridge over the river was in danger of being undermined by the water which flowed through the ditch. The owner .of the land which was overflowed by the water fro hi the ditch brought suit against defendant to frecover the damages caused thereby, and, in compromise of that suit, defendant agreed that it would either enlarge the ‘ditch, or reopen the passage7way for the water through the embankment. It elected to take the latter course, and was proceeding to open a -water-way through the embankment when this suit was instituted.
Between the time of the construction of the railroad and the closing of the water-way, in 1879, there had been a *698material increase in the amount of water which flowed through the slough, caused by ditches, which had been constructed by the owners of some of the land which drained into the slough, for the reclamation or improvement of their lands. And during the time the water-way was closed there had also been an increase in the amount of water in the slough, resulting from like causes. Plaintiff’s land is south of the track. It does not abut on defendant’s right of way, but, if the water-way through the embankment should be opened, the water which will flow through it, after passing over the intervening land, will enter upon his premises, and overflow and render unfit for cultivation a portion of his land. It will also overflow, and at times render impassable, a highway which affords plaintiff the most convenient way of access to the town at which he trades.
The question which arises upon the facts is whether defendant is bound to maintain the embankment in such condition as to protect plaintiff’s premises and said highway from the water which comes upon its right of way through said slough. It has not been claimed that defendant originally owed plaintiff any duty in that respect. Before 'its railroad was constructed, the water naturally flowed through the slough, and found its way onto plaintiff’s premises, and at times portions of his land and the highway were overflowed by it. Very clearly plaintiff had no right originally to demand that the embankment should be so constructed and maintained as to form a protection to his premises against the water. The position urged by counsel, however, is that, when defendant assumed to take charge of the water, and undertook to conduct it to the river through another channel, it relinquished all right to have it conducted, away from its premises by the natural channel, and, as the reopening of the water-way through the embankment would work an injury to the lower estate, it is now estopped from opening it.
But it is very clear, we think, that plaintiff is not entitled *699to recover on the ground that defendant is estopped by its previous acts from opening the water-way. What was done by defendant had the appearance, it is true, of being a permanent work. Put it is an essential element of an estoppel in pais that the one pleading it, or those under whom he claims, should have relied on the act or representation alleged, and been induced by it to alter his position with reference to the subject to which it related. 2 Pars. Cont. 703; Lucas v. Hart, 5 Iowa, 415.
It is not claimed, however, that plaintiff did anything in reliance on the permanency of the work done by defendant. The closing of the water-way had the effect to render arable the portions of his land which before that were subject to overflow, and he cultivated them. He simply availed himself of such benefits as resulted from the act done by defendant, but he did nothing' himself • which contributed to the result. If the water-way should he opened, he v^ould be placed in precisely the same position he would have occupied if it had never been closed. This essential element of an estoppel is clearly wanting in the case. When defendant constructed its embankment, it had the undoubted right to leave a way for the passage of the water through it. Py so doing it neither increased the amount of.water, nor otherwise changed the flow upon the lower estate. It simply permitted it to flow through its premises by its natural course.
As the water was mere surface water, it had the.right to « make provision for the protection of its premises from injury from it. Its act in closing the passage-way through the embankment, and constructing the ditch, was not an invasion of any of plaintiff’s rights. Neither did it create any new duty or obligation from it to him. There is no legal principle upon which it can be said that defendant is bound to protect plaintiff’s premises for all time from the surface water which would flow upon them, because for a time it maintained a work which had that effect. The work was *700done originally for the amelioration of defendant’s estate, and.in that respect it was lawful; but the relative rights and obligations of the parties remained the same after as before it was done.
The fact that a greater quantity of water will flow through the water-way than did before it was closed, does not affect the rights or obligations of these parties.' That effect will follow, not from anything which defendant lias done or proposed to do, but will be the result of what has been done by other parties. We need not inquire whether those acts are unlawful or not, for, if it should be conceded that they are unlawful, defendant is under no obligation to protect plaintiff from the consequences which will result from them. If the act of the adjacent land-owners in draining their land into the slough was wrongful, defendant lias the right, doubtless, to take such action as would protect its own premises from injury by the increased amount of water thrown upon them. But it is not under obligation to protect plaintiff’s premises from injury by that cause.
