The judgment restraining the defendant, from interfering with the gate and other structures of the plaintiff at the outlet of the pond, can be sustained only in case the plaintiff has the right to maintain the dam and other structures, and thereby control the flow of the water in the manner and for the purposes found by the Special Term. It was controlled by him; and for affecting which, the structures were erected. Prom these facts it appears, that the dam and structures were erected at the outlet of a natural pond of about forty ..acres, into which one or more small streams run, having
*515
but a small quantity of water in a dry time flowing therein. But in the wet seasons, spring and fall, a much larger quantity flowed into and out of the pond. That the dam was constructed about ten feet above the natural outlet of the pond, and used to detain the water in the pond during such portions of the year as the plaintiff’s factory was adequately supplied 'with water from a stream below the dam. (The latter a stream originating from another source.) And when this failed to furnish an adequate supply, the deficiency was supplied from the reservoir, in a steady and constant manner . through a gate in a trunk of about a foot square. That the waters have been retained and used by the plaintiff with the sole view of economizing and utilizing the same, to the greatest possible extent, not viciously or with any intent to injure, or in any way wrong the defendant. It further appears from such finding, that the water was so detained by the plaintiff during the wet seasons in the spring and fall, until .wanted for use by the plaintiff in the dry seasons of winter and summer. The judgment, in effect, determines, that the plaintiff has a right so to detain and use the water, it being necessary so to do, to give an adequate and profitable power to propel the machinery of a factory owned by him, situate about three miles below the outlet as against the defendant. The defendant is the owner of a parcel of land, situated upon both sides of the stream between the outlet and the plaintiff’s factory, upon which there is a saw-mill operated by the defendant during portions of the year. The question to be determined is of great importance to the plaintiff, the case showing that his factory is of great value, which will be much impaired, if not wholly destroyed, by not enjoying the right to control and use the water in the manner claimed by him in this action. While this consideration should induce care in the examination of the case, it can have no weight in the determination of the legal rights of the parties. It is the duty of the court to apply the law as it is to the facts of every case, and give to every party his legal rights, irrespective of any hardship that may be thereby caused in any special case. It
*516
is necessary to examine the question as to the rights of riparian owners, as the judgment for the plaintiff, to its full extent, depends wholly upon those rights. Kent (3 Com., 439) says, that every proprietor of lands on the banks of a river, has naturally an equal right to the use of water which flows in the stream adjacent to his lands, as it was wont to run
{eurrere
solebat), without diminution or alteration: No proprietor has a right to use the water, to the prejudice of other proprietors, above or below him, unless he has a prior right to divert it, or a title to some exclusive enjoyment. He has no p;operty in the water itself, but a simple usufruct while it passes along.
“Aqua, ewrritet debet eurrereut eurrere solebat”
is the language of the law. Though he may use the water while it runs over his land as an incident to the land, he cannot unreasonably detain it or give it another direction, and he must return it .to its ordinary channel when it leaves his estate. In
