opinion: Justice White
  delivered the opinion of the Court.
  Under review here is a decision of the Court of Appeals for the Ninth Circuit holding that private parties may sue under the Rivers and Harbors Appropriation Act of 1899 to enforce § 10 of that Act. An environmental organization and two private citizens (hereafter respondents) seek to enjoin the construction and operation of water diversion facilities which are part of the California Water Project (CWP). They rely upon § 10 of the Act, which prohibits “[t]he creation of any obstruction not affirmatively authorized by Congress, to the navigable capacity of any of the waters of the United States . ...” Since the Act does not explicitly create a private enforcement mechanism, the initial question presented by these consolidated cases is whether such a private right of action can be implied on behalf of those allegedly injured by a claimed violation of § 10. Petitioner State of California also asks us to decide whether the Act requires permits for the state water allocation projects involved in these cases.
  I
  The California Water Project consists of a series of water storage and transportation facilities designed primarily to transport water from the relatively moist climate of northern California to the more arid central and southern portions of the State. The water which will be used by the CWP is initially stored behind dams on the Sacramento River and, as needed, released into the Sacramento-San Joaquin Delta. The CWP then diverts a quantity of this water from the Delta and directs it into canals and aqueducts which will carry it south. The project has both federal and state components. The federal component, the Central Valley Project, is designed in part to provide a constant source of water for irrigation to the Central Valley of California. Water for this project is diverted from the Delta by the Tracy Pumping Plant into the 115-mile Delta-Mendota Canal which transports the water to the Mendota Pool in California’s Central Valley. The State Water Project supplies water to both central and southern California by way of the California Aqueduct. Water for this project is drawn from the Delta by the Delta Pumping Plant and deposited in the northern terminus of the California Aqueduct, through which it flows to its destinations in central and southern California.
  Under the present system the quality of water captured in the north and released into the Delta may be degraded by intruding salt waters from the Pacific Ocean. As a consequence the water which is diverted from the Delta to the Delta-Mendota Canal or the California Aqueduct is potentially of a lesser quality than is the water which is transported to the Delta from storage facilities in the north and from there deposited in the Delta. The State of California has proposed the construction of a 42-mile Peripheral Canal along the eastern edge of the Delta area, which would avoid any mixing of the water from the north with the saline water of the Delta. Instead of depositing water in the Delta, the canal would carry high quality water directly to the Tracy and Delta Pumping Plants.
  Respondents commenced the present action in 1971 in the United States District Court for the Northern District of California. Sierra Club v. Morton, 400 P. Supp. 610 (1975). Named as defendants were the various federal and state officials who administer the agencies responsible for overseeing the operation, construction, and regulation of the CWP facilities in question. Petitioner water agencies, which had contracted with the State for water from the Delta and which had incurred extensive financial obligations in reliance thereon, were permitted to intervene. The respondents alleged that present and proposed diversions of water from the Delta degraded the quality of Delta water, and that such diversion violated § 10 of the Rivers and Harbors Appropriation Act of 1899. They sought to enjoin further operation or construction of water diversion facilities until the consent of the Army Corps of Engineers was obtained as required by the Act.
  The District Court concluded that respondents could avail themselves of a “private cause of action” to enforce § 10 of the Act, and ruled on the merits that approval of the Corps of Engineers was required by § 10 for the Tracy and Delta Pumping Plants and the Peripheral Canal. Sierra, Club v. Morton, supra. The Court of Appeals for the Ninth Circuit agreed that a private cause of action to enforce the Act existed. Sierra Club v. Andrus, 610 F. 2d 581 (1979). It reversed the District Court as to the Tracy Pumping Plant, however, ruling that Congress has consented to its construction and operation. We granted petitions for certiorari filed by the water agencies and the State of California. 449 U. S. 818 (1980).

  Cort v. Ash, 422 U. S. 66 (1975), outlined a “preferred approach for determining whether a private right of action should be implied from a federal statute . . . .” Transamerica Mortgage Advisors, Inc. v. Lewis, 444 U. S. 11, 26 (1979) (White, J., dissenting); see Cannon v. University of Chicago, 441 U. S. 677 (1979). This approach listed four factors thought to be relevant to the inquiry:
  “First, is the plaintiff 'one of the class for whose especial benefit the statute was enacted/ . . . —that is, does the statute create a federal right in favor of the plaintiff? Second, is there any indication of legislative intent, explicit or implicit, either to create such a remedy or to deny one? . . . Third, is it consistent with the underlying purposes of the legislative scheme to imply such a remedy for the plaintiff? . . . And finally, is the cause of action one traditionally relegated to state law, in an area basically the concern of the States, so that it would be inappropriate to infer a cause of action based solely on federal law?” 422 U. S., at 78.
  Combined, these four factors present the relevant inquiries to pursue in answering the recurring question of implied causes of action. Cases subsequent to Cort have explained that the ultimate issue is whether Congress intended to create a private right of action, see Universities Research Assn., Inc. v. Coutu, 450 U. S. 754, 771-772 (1981); Transamerica Mortgage Advisors, Inc. v. Lewis, supra, at 23-24; Touche Ross & Co. v. Redington, 442 U. S. 560, 568, 575-576 (1979); but the four factors specified in Cort remain the “criteria through which this intent could be discerned.” Davis v. Passman, 442 U. S. 228, 241 (1979); Transamerica Mortgage Advisors, Inc. v. Lewis, supra, at 27 (White, J., dissenting).
  Under Cort, the initial consideration is whether the plaintiff is a -member of a class for “ 'whose especial benefit the statute was enacted.’ ” Cort v. Ash, supra, at 78, 80-82; see Touche Ross & Co. v. Redington, supra, at 569-570; Cannon v. University of Chicago, supra, at 689-694. Without analyzing either the language or legislative history of the Act, the Court of Appeals here concluded that the Act was designed for the especial benefit of private parties who may suffer “special injury” caused by an unauthorized obstruction to a navigable waterway. It was apparently reasoned that since Congress enacted a statute that forbids such obstructions in navigable waters, any person who would be “especially harmed” by an unauthorized obstruction was an especial beneficiary of the Act. But such a definition of “especial” beneficiary makes this factor meaningless. Under this view, a victim of any crime would be deemed an especial beneficiary of the criminal statute’s proscription. Cort did not adopt such a broad-gauge approach. Cort v. Ash, supra, at 80-82. The question is not simply who would benefit from the Act, but whether Congress intended to confer federal rights upon those beneficiaries. See Cannon, supra, at 690-693, n. 13.
  In ascertaining this intent, the first consideration is the language of the Act. Here, the statute states no more than a general proscription of certain activities; it does not unmistakably focus on any particular class of beneficiaries whose welfare Congress intended to further. Such language does not indicate an intent to provide for private rights of action. “There would be far less reason to infer a private remedy in favor of individual persons if Congress, instead of drafting Title IX [of the Education Amendments of 1972] with an unmistakable focus on the benefited class, had written it simply as a ban on discriminatory conduct by recipients of federal funds or as a prohibition against the disbursement of public funds to educational institutions engaged in discriminatory practices.” Cannon v. University of Chicago, supra, at 690-693; see also Touche Ross & Co. v. Redington, supra, at 569; Cort v. Ash, supra, at 80-82. Section 10 of the Rivers and Harbors Appropriation Act is the kind of general ban which carries with it no implication of an intent to confer rights on a particular class of persons.
  Neither the Court of Appeals nor respondents have identified anything in the legislative history suggesting that § 10 was created for the especial benefit of a particular class. On the contrary, the legislative history supports the view that the Act was designed to benefit the public at large by empowering the Federal Government to exercise its authority over interstate commerce with respect to obstructions on navigable rivers caused by bridges and similar structures. In part, the Act was passed in response to this Court’s decision in Willamette Iron Bridge Co. v. Hatch, 125 U. S. 1 (1888). There the Court held that there was no federal common law “which prohibits obstructions and nuisances in navigable rivers.” Id., at 8. Although Willamette involved private parties, the clear implication of the Court’s opinion was that in the absence of specific legislation no party, including the Federal Government, would be empowered to take any action under federal law with respect to such obstructions. The Act was intended to enable the Secretary of War to take such action. See 21 Cong. Rec. 8603, 8605, and 8607 (1890); see also United States v. Pennsylvania Industrial Chemical Corp., 411 U. S. 655, 663-664 (1973); United States v. Standard Oil Co., 384 U. S. 224, 227-229 (1966); United States v. Republic Steel Corp., 362 U. S. 482, 485-488, 499-500 (1960). Congress was not concerned with the rights of individuals.
  It is not surprising, therefore, that there is no “indication of legislative intent, explicit or implicit, either to create such a remedy or to deny one.” Cort v. Ash, 422 U. S., at 78, 82-84; Touche Ross & Co. v. Redington, 442 U. S., at 571; Cannon v. University of Chicago, 441 U. S., at 694-703. The Court of Appeals recognized as much: “The legislative history of the Rivers and Harbors Act of 1899 does not reflect a congressional intent either to afford a private remedy or to deny one.” 610 F. 2d, at 588. This silence on the remedy question serves to confirm that in enacting the Act, Congress was concerned not with private rights but with the Federal Government’s ability to respond to obstructions on navigable waterways.
  As recently emphasized, the focus of the inquiry is on whether Congress intended to create a remedy. Universities Research Assn., Inc. v. Coutu, 450 U. S., at 771-772; Transamerica Mortgage Advisors, Inc. v. Lewis, 444 U. S., at 23-24; Touche Ross & Co. v. Redington, supra, at 575-576. The federal judiciary will not engraft a remedy on a statute, no matter how salutary, that Congress did not intend to provide. Here consideration of the first two Cort factors is dispositive. The language of the statute and its legislative history do not suggest that the Act was intended to create federal rights for the especial benefit of a class of persons but rather that it was intended to benefit the public at large through a general regulatory scheme to be administered by the then Secretary of War. Nor is there any evidence that Congress anticipated that there would be a private remedy. This being the case, it is unnecessary to inquire further to determine whether the purpose of the statute would be advanced by the judicial implication of a private action or whether such a remedy is within the federal domain of interest. These factors are only of relevance if the first two factors give indication of congressional intent to create the remedy. Touche Ross & Co. v. Redington, supra, at 574-576. There being no such indication, the judgment of the Court of Appeals must be reversed.
  Ill
  Petitioner the State of California urges that we reach the merits of these cases — whether permits are required for the state water allocation projects — regardless of our disposition of the private-cause-of-action issue. This we decline to do. Our ruling that there is no private cause of action permitting respondents to commence this action disposes of the cases: we cannot consider the merits of a claim which Congress has not authorized respondents to raise.
  The judgment of the Court of Appeals is accordingly reversed, and the cases are remanded for proceedings consistent with this opinion.
  It is so ordered.
  The Sierra Club is a nonprofit California corporation; Hank Schramm is a commercial fisherman active in the San Francisco Bay and Pacific Ocean; and William Dixon is a Saeramento-San Joaquin Delta landowner. See 400 F. Supp. 610, 619 (ND Cal. 1975).
  Section 10 of the Rivers and Harbors Appropriation Act of 1899 provides:
  “The creation of any obstruction not affirmatively authorized by Congress, to the navigable capacity of any of the waters of the United States is prohibited; and it shall not be lawful to build or commence the building of any wharf, pier, dolphin, boom, weir, breakwater, bulkhead, jetty, or other structures in any port, roadstead, haven, harbor, canal, navigable river, or other water of the United States, outside established harbor lines, or where no harbor lines have been established, except on plans recommended by the Chief of Engineers and authorized by the Secretary of the Army; and it shall not be lawful to excavate or fill, or in any manner to alter or modify the course, location, condition, or capacity of, any port, roadstead, haven, harbor, canal, lake, harbor or refuge, or inclosure within the limits of any breakwater, or of the channel of any navigable water of the United States, unless the work has been recommended by the Chief of Engineers and authorized by the Secretary of the Army prior to beginning the same.” 30 Stat. 1151, 33 U. S. C. § 403.
  The federal defendants were the Secretary of the Interior, the Commissioner of the Bureau of Reclamation, the Secretary of the Army, the Chief of Engineers of the Army Corps of Engineers, and the Division Engineer of the Corps’ South Pacific Division. The state defendants were the Secretary for Resources and the Director of the Department of Water Resources. 400 F. Supp., at 620.
  According to affidavits filed in 1974 in support of motions to intervene, Kern County Water Agency has contracted to purchase up to 1,153,000 acre-feet annually, which is resold primarily to agricultural users. The Metropolitan Water District of Southern California has contracted to purchase up to 2,011,500 acre-feet annually to serve the water needs of an area of some 4,900 square miles with 10 million inhabitants. The Tulare Lake Basin Water Storage District and the Santa Clara Valley Water District have contracted to purchase lesser amounts. See App. 99a-112a.
  Judge Tang wrote separately to explain why the conclusion that the Tracy Pumping Plant had been authorized by Congress did not conflict with the Ninth Circuit’s recent decision in Libby Rod & Gun Club v. Poteat, 594 F. 2d 742 (1979). 610 F. 2d, at 607.
  In addition, § 12 of the Act, 33 U. S. C. § 406, provides criminal penalties for violations of the provisions .of various sections of the Act, including the provisions of § 10; and, § 17 of the Act, 33 U. S. C. §413, provides that “[t]he Department of Justice shall conduct the legal proceedings necessary to enforce the provisions of [§ 10].” The creation of one explicit mode of enforcement is not dispositive of congressional intent with respect to other complementary remedies. See Cort v. Ash, 422 U. S. 66, 82-83, n. 14 (1975); Transamerica Mortgage Advisors, Inc. v. Lewis, 444 U. S. 11, 29, n. 6 (1979) (White, J., dissenting). However, here, considering the clear focus of the legislative history on the need to enable the Government to respond to obstructions in navigable waterways, the creation of this enforcement mechanism and the absence of the remedy sought by respondents, certainly reinforces the view that Congress was not concerned with private rights or remedies in designing this legislation.
  Respondents suggest that the legislative history of the Act must be read in light of the historical context during which the measure was being considered. See Cannon v. University of Chicago, 441 U. S. 677, 698-699 (1979). That context, they argue,'included a general awareness that the obstruction of any navigable stream could have been addressed through the common law of nuisance and that this private remedy had been recognized at one time as federal in nature. Furthermore, they argue that the contemporary legal climate recognized that the abrogation of this federal remedy in cases such as Willamette Iron Bridge Co. v. Hatch, 125 U. S. 1 (1888), did not undermine the accepted view that the enactment of any federal prohibition of obstructions on navigable streams would resurrect the federal private right of action. Congressional silence as to private remedies should be interpreted, therefore, as acquiescing in the accepted view.
  For both of these positions respondents rely heavily upon Pennsylvania v. Wheeling & Belmont Bridge Co., 13 How. 518 (1852). There, the State of Pennsylvania sought equitable relief from the construction of a bridge across the Ohio River. The Court took the case under its original jurisdiction, a State being the plaintiff, and, having done so, held that it was empowered to consider all issues presented by the parties, state as well as federal. Respondents suggest that the Wheeling Court held that federal courts were regularly available to entertain actions for nuisance brought by private parties with respect to obstructions on navigable rivers. But nothing in the opinion supports that view. The discussion in that case of the common law of nuisance is based on the Court’s position that it was entitled to consider state as well as federal issues in the cause before it. Indeed, that the opinion did not establish a general federal law of nuisance with respect to navigable waterways was a point reiterated in Willamette, supra, at 15-17. In short, although there may have been a common-law nuisance cause of action for obstructions of navigable waterways, Wheeling Bridge did not federalize that law. Respondents have cited no decision by this Court that did.
  Equally unavailing is respondents’ assertion that Wheeling Bridge stands for the broad proposition that if Congress legislated in this area, any prohibition of obstructions would automatically support a private right of action. This position is extrapolated from discussions of the law of nuisance in both Wheeling Bridge, supra, at 604-607 and the subsequent Gilman v. Philadelphia, 3 Wall. 713, 722-724 (1866). In both cases the Court merely expressed agreement with the proposition that a court of equity could enjoin a public nuisance in a case brought by a private person who had sustained specific injury. Whether a congressional enactment prohibiting obstructions would automatically give rise to a private right of action was not an issue raised or discussed in either case.
  The most that may be legitimately concluded as to legislative understanding of the law preceding the enactment of this statute is that Congress was aware that the Supreme Court had held that there was no federal law which empowered anyone to contest obstructions to navigable rivers. See 21 Cong. Rec. 8604r-8607 (1890). We cannot assume from legislative silence on private rights of action, that Congress anticipated that a general regulatory prohibition of obstructions to navigable streams would provide an automatic basis for a private remedy in the nature of common-law nuisance. The Rivers and Harbors Appropriation Act of 1899 was no doubt in part a legislative response to the Willamette decision. But there is nothing to suggest that that response was intended to do anything more than empower the Federal Government to respond to obstructions on navigable rivers. The broad view supported by respondents is without support.
