THE MAYOR, RECORDER, ALDERMEN, AND COMMON COUNCIL OF GEORGETOWN, APPELLANTS
v.
THE ALEXANDRIA CANAL COMPANY, AND WILLIAM TURNBULL, APPELLEES.
Supreme Court of United States.

*94 The case was argued by Mr. Key, for the appellants; and by Coxe and Mr. Jones, for the appellees.
Mr. Justice BARBOUR delivered the opinion of the Court.
This is an appeal from a decree of the circuit court of the United States for the county of Washington, in the District of Columbia, dismissing the appellants' bill.
The appellants filed their bill in the court below, in behalf of themselves and the citizens of Georgetown, against the appellees; containing various allegations, the material parts of which, are substantially these: That the appellees, who were defendants in the court below, had been, and then were engaged in constructing an *95 aqueduct over the Potomac river, at Georgetown, within its corporate limits, immediately above, and west of the principal public and private wharves of the town; that the Potomac river, above and below the aqueduct, continuously outward to the sea, was a public navigable highway; that the free use of that river was secured to all the people, residing on its borders or interested in its navigation, by a compact between the states of Virginia and Maryland, in the year 1785; that Georgetown derived its chief support and prosperity from the trade of the Potomac; that large sums of money had been expended by the complainants, at the wharves of the town, in deepening the water on the bar across the main channel, immediately below the town, and north and west of the long bridge across the Potomac; that the defendants had constructed one massive stone pier, and were about to construct others; that by the use of clay and earth thrown in, to make close certain coffer dams, used by the defendants in the construction of the piers, the harbour has been injured, and the depth of water in the cut or channel through the bar below the town, has been diminished already, and that they apprehend serious injury in future from the same causes; that by the construction of their piers of stone, and in such a way, as greatly to increase the force of the current, other earth and mud have been, and will be washed down by the velocity of the current, so as to injure the wharves and harbour of the town, and impair the navigation of the river. The bill charges, that the aqueduct can be constructed without the use of clay and earth, from which so much injury is apprehended. It proceeds to state, in minute detail, the nature and character of the injury apprehended to the harbour, wharves, and navigation; and concludes with a prayer for an injunction prohibiting the defendants from further depositing earth and clay in the Potomac river, outside, or inside their coffer dams, or otherwise, to the injury of the navigation of the river and the harbour of Georgetown; and with a prayer also for general relief.
The defendants answered, denying that the complainants, the Corporation of Georgetown, had any right, title, or interest in the waters of the Potomac river, which they aver to be a public navigable river, and a common highway; they deny that the works, in the construction of which they are engaged, are within the corporate limits of Georgetown; they deny the right of the Corporation of Georgetown, to file the bill in behalf of the citizens of the town; they deny the jurisdiction of a court of equity, over nuisances in public rivers *96 and highways; and also its power to enjoin them from the prosecution of the works in which they are engaged, under their charter; they insist, that congress had full power to grant to them the charter of incorporation, and to authorize the construction of the works in which they are engaged. They aver that they have not transcended the power conferred by their charter, which was granted to them by an act of congress, passed on the 26th of May, 1830; which they exhibit as part of their answer. They then proceed to answer the bill at large upon its merits.
It is unnecessary to state the evidence in the case; because our opinion is founded upon considerations, independent of the facts which that evidence was intended to prove.
We shall forbear also from any expression of opinion upon some of the topics discussed at the bar; because, whilst they are important in their character, they have no bearing upon the principles on which our judgment proceeds.
We will now very briefly state them, and the conclusions which necessarily flow from them. The compact made in the year 1785, between Virginia and Maryland, was made by the two states, in their character as states. The citizens, individually, of both commonwealths, were subject to all the obligations imposed, and entitled to all the benefits conferred by that compact. But the citizens as such, individually, were in no just sense the parties to it: those parties were the two states, of which they were citizens. The same power which established it, was competent either to annul or to modify it. Virginia and Maryland, then, if they had retained the portions of territory respectively belonging to them on the right and left banks of the Potomac; could have so far modified this compact as to have agreed to change any or all of its stipulations. They could, by their joint will, have made any improvement which they chose, either by canals along the margin of the river, or by bridges or aqueducts across it, or in any other manner whatsoever
When they ceded to congress the portions of their territory, embracing the Potomac river, within their limits, whatsoever the legislatures of Virginia and Maryland could have done by their joint will, after that cession could be done by congress; subject only to the limitations imposed by the acts of cession.
We are satisfied, then, that the act of congress, which granted the charter to the Alexandria Canal Company, is in no degree a violation of the compact between the states of Virginia and Maryland, or of *97 any rights that the citizens of either, or both states, claimed as being derived from it.
Congress then, having the power, authorized the Alexandria Canal Company "to cut canals, erect dams, open feeders, construct locks, and perform such other works, as they shall judge necessary and expedient, for completing a canal, from the termination or other point on the Chesapeake and Ohio Canal, to such place in the town of Alexandria, as the board of directors shall appoint." Now, as one of its terminii was authorized to be, either the termination or some other point on the Chesapeake and Ohio Canal, and the other some place in the town of Alexandria; and as the Potomac lies between these terminii; the authority to construct an aqueduct was granted ex necessitate. But, if certainty required to be made more certain, this is done by the language of the ninth and fourteenth sections of the act of May 26th, 1830, granting the charter; in both of which the term aqueducts is used, in such a manner as incontestably to prove, that congress considered the power to construct them as given by the charter.
If, then, as we have said, congress had power to authorize the construction of an aqueduct across the Potomac; if so having the power, they have given to the Alexandria Canal Company the authority to construct it; and if, in the construction, that company has not exceeded the authority given them, either in the thing done, or in the manner of doing it, so as to produce the least injury or inconvenience practicable, consistently with the execution of the work; it would be difficult, as a legal proposition, to predicate of such a work, that it was unlawful, or that it was a nuisance; so as to justify a court in interfering to prevent its progress towards completion.
It is unnecessary, however, to prosecute this inquiry, because there is a view of this subject which we think decisive of the case.
Were it even admitted that the Canal Company had exceeded the authority under which they are acting, nevertheless, as the Potomac river is a navigable stream, a part of the jus publicum, any obstruction to its navigation would, upon the most established principles, be what is declared by law to be a public nuisance. A public nuisance being the subject of criminal jurisdiction, the ordinary and regular proceeding at law is by indictment or information, by which the nuisance may be abated; and the person who caused it may be punished. If any particular individual shall have sustained special *98 damage from the erection of it, he may maintain a private action for such special damage; because to that extent he has suffered beyond his portion of injury, in common with the community at large. 5th Bac. Abridg. Nuisance, B. p. 51. 2d Lord Raym. 1163.
Besides this remedy at law, it is now settled, that a court of equity may take jurisdiction in cases of public nuisance, by an information filed by the attorney general. This jurisdiction seems to have been acted on with great caution and hesitancy. Thus, it is said by the Chancellor, in 18th Vesey, 217, that the instances of the interposition of the court were confined and rare. He referred, as to the principal authority on the subject, to what had been done in the court of exchequer, upon the discussion of the right of the attorney general by some species of information, to seek on the equitable side of the court, relief as to nuisance, and preventive relief.
Chancellor Kent in 2d John. Chan. 382, remarks, that the equity jurisdiction, in cases of public nuisance, in the only cases in which it had been exercised, that is, in cases of encroachment on the king's soil, had lain dormant for a century and a half; that is, from Charles I. down to the year 1795.
Yet the jurisdiction has been finally sustained; upon the principle that equity can give more adequate and complete relief than can be obtained at law. Whilst, therefore, it is admitted by all that it is confessedly one of delicacy; and accordingly, the instances of its exercise are rare, yet it may be exercised in those cases in which there is imminent danger of irreparable mischief before the tardiness of the law could reach it.
The court of equity, also, pursuing the analogy of the law, that a party may maintain a private action for special damage, even in case of a public nuisance, will now take jurisdiction in case of a public nuisance, at the instance of a private person; where he is in imminent danger of suffering a special injury, for which, under the circumstances of the case, the law would not afford an adequate remedy. Amongst other cases, this doctrine is laid down in the case of Crowder v. Tinkler, 19 Vesey, 616. In that case, p. 622, the chancellor says, "Upon the question of jurisdiction, if the subject was represented as a mere public nuisance, I could not interfere in this case, as the attorney general is not a party; and if he was a party upon the dicta, unless it was clearly a public nuisance generally, the court would not interpose by injunction until it had been tried at law. The complaint is, therefore, to be considered as of not *99 a public nuisance simply; but what, being so in its nature, is attended with extreme probability of irreparable injury to the property of the plaintiffs, including, also, danger to their existence; and on such a case, clearly established, I do not hesitate to say an injunction would be granted."
The principle is also distinctly asserted and acted on by Chancellor Kent, in the case of Corning and others v. Lowerre, 6 John. Chan. 439. In that case, a bill was filed for an injunction to restrain the defendant from obstructing Vestry street, in the city of New York, and averring that he was building a house upon that street, to the great injury of the plaintiffs, as owners of lots on and adjoining that street; and that Vestry street had been laid out, regulated and paved, for about twenty years.
The injunction was granted: the Chancellor said, that here was a special grievance to the plaintiffs, affecting the enjoyment of their property and the value of it. The obstruction was not only a common or public nuisance, but worked a special injury to the plaintiffs.
The principle then is, that in case of a public nuisance, where a bill is filed by a private person, asking for relief by way of prevention, the plaintiff cannot maintain a stand in a court of equity; unless he avers and proves some special injury.
With this principle as our guide, let us now examine the pretensions of the appellants in this case. Who are they? Not, indeed, a private person, but a corporation. They profess to come into court for themselves, and for the citizens of Georgetown. Now, it is not even pretended that, in their character of a corporation only, they have any power or authority given to them by their charter; to take care of, protect, and vindicate, in a court of justice, the rights of the citizens of the town, in the enjoyment of their property, or in removing or preventing any annoyance to it. Nor does such a power attach to them in their corporate character, upon any principle of the law in relation to corporations. The complainants, then, must, as in the case of private persons, to maintain their position in a court of equity for relief against a public nuisance, have averred and proved, that they were the owners of property liable to be affected by the nuisance, and that, in point of fact, were so affected, so as that they thereby had suffered a special damage. Now, there is no such averment in this bill. The appellants seem to have proceeded on the idea, that it appertained to them, as the corporate authority in *100 Georgetown, to take care of and protect the interests of the citizens. In this idea we think they were in error; and that they cannot, upon any principle of law, be recognised as parties competent in court to represent the interests of the citizens of Georgetown. Nor is the difficulty obviated by associating with them the citizens of Georgetown, as persons in whose behalf they sue. There are indeed cases, in which it is competent for some persons to come into a court of equity, as plaintiffs for themselves and others, having similar interests: such is the familiar example of what is called a creditors' bill. But in that, and all other cases of a like kind, the persons, who by name, bring the suit, and constitute the parties on the record, have themselves an interest in the subject matter, which enables them to sue, and the others are treated as a kind of co-plaintiffs with those named, although they themselves are not named; but in this case, it has been already said, that the appellants have no such interest as enables them to sue in their own name, and consequently the whole analogy fails. Moreover, if the citizens of Georgetown were even parties on the record; the objection would equally lie against them, unless they could show a special damage as a ground to stand upon.
With these views, we are of opinion that the decree of the court below, dismissing the appellants' bill, is correct; it is therefore affirmed, with costs.
This cause came on to be heard on the transcript of the record from the circuit court of the United States for the District of Columbia, holden in and for the county of Washington, and was argued by counsel; on consideration whereof, it is decreed and ordered by this Court, that the decree of the said circuit court in this cause be, and the same is hereby affirmed, with costs.
