    4                   TREACY v. NEWDUNN ASSOCIATES
    OPINION
    GREGORY, Circuit Judge:
    During the summer of 2001, without obtaining a permit from the
    Army Corps of Engineers (the "Corps") or the Virginia State Water
    Control Board (the "Board"), Newdunn Associates, Orion Associates,
    and Northwest Contractors (collectively "Newdunn") began ditching
    and draining wetlands on a forty-three-acre property near Newport
    News, Virginia (the "Newdunn Property"). Pursuant to its authority
    under the Clean Water Act ("CWA" or the "Act"), the Corps brought
    a civil enforcement action in federal district court. The Board initiated
    its own enforcement action in state court, premised on the Virginia
    Nontidal Wetlands Resources Act of 2000 (the "Virginia Act").
    Newdunn removed the state action to federal court, and the two cases
    were consolidated. After a five-day bench trial, the district court ruled
    for Newdunn in both cases, finding that the Corps lacked jurisdiction
    over wetlands on the Newdunn Property under the Clean Water Act,
    and that the jurisdictional reach of Virginia law was merely coexten-
    sive with federal law. For the reasons stated below, we reverse.
    I.
    In 1978, Newdunn Associates purchased forty-three acres of land
    located in Newport News, Virginia. It is undisputed that approxi-
    mately thirty-eight acres of the Newdunn Property (the "Newdunn
    Wetlands") were "wetlands," as that term is defined by the Corps in
    its CWA regulations. 
    33 C.F.R. § 328.3
    (b) (2002) (defining "wet-
    lands" as "those areas that are inundated or saturated by surface or
    ground water at a frequency and duration sufficient to support, and
    that under normal circumstances do support, a prevalence of vegeta-
    tion typically adapted for life in saturated soil conditions"). Histori-
    cally, before the construction of Interstate 64 ("I-64"), the wetlands
    on the Newdunn Property had a natural hydrologic connection to
    Stony Run, which is a navigable waterway-in-fact. Presently, the
    Newdunn Wetlands remain connected to the navigable waters of
    Stony Run by the intermittent flow of surface water through approxi-
    mately 2.4 miles of natural streams and manmade ditches (paralleling
    and crossing under I-64). Silt-laden waters from the Newdunn Wet-
    TREACY v. NEWDUNN ASSOCIATES                       5
    lands merge with clear water flowing south of the manmade ditch on
    the west side of I-64.
    In May of 2001, following the Supreme Court’s ruling in Solid
    Waste Agency of N. Cook County ("SWANCC") v. United States, 
    531 U.S. 159
    , 167 (2001), which struck down the Corps’ attempted exer-
    cise of jurisdiction under its Migratory Bird Rule, Newdunn informed
    the Corps that it believed the Corps lacked jurisdiction over the
    Newdunn Property, and began filling the Newdunn Wetlands without
    a permit. Newdunn argued that there were no "jurisdictional" wet-
    lands on the property, even though the property contained "scientific"
    wetlands. The Corps disagreed with Newdunn’s interpretation of
    SWANCC, and on July 6, 2001, attempted to assert jurisdiction over
    wetlands on the Newdunn Property by commencing an enforcement
    action in federal district court, alleging violations of sections 301 and
    404 of the Clean Water Act.
    Based on the same activities, and pursuant to Virginia state law, the
    Board issued an Emergency Special Order ("ESO"), mandating that
    Newdunn cease stumping and grading on its property. Va. Code. Ann.
    § 62.1-44.15(8b). Newdunn ignored the ESO, and as a result, on
    August 7, 2001, the Board filed a civil enforcement action in state
    court, alleging violations of 
    Va. Code Ann. §§ 62.1-44.5
    , 62.1-44.14,
    62.1-44.15, 62.1-44.15:5, 62.1-44.23, and 62.1-44.32 (2001).
    Newdunn removed the Board’s action to federal court. The Board,
    claiming that the district court was without jurisdiction to consider its
    case, filed a motion to remand. The court denied the Board’s motion,
    and the Corps’ and the Commonwealth’s cases were consolidated for
    a five-day bench trial in March of 2002.
    As to the federal suit, the district court held that the Corps’ wet-
    lands regulations were invalid because they exceeded Congress’ grant
    of authority to the Corps under the Clean Water Act. On the state suit,
    the court ruled that the Commonwealth "has been unable to show that
    the Virginia Legislature has, at this time, granted regulatory authority
    independently of the Corps’ jurisdiction." Accordingly, the district
    court determined that the Commonwealth lacked jurisdiction over the
    Newdunn Wetlands, since its authority was presumably coextensive
    with the Corps’. This consolidated appeal followed.

    II.
    We review de novo both the district court’s statutory interpretation
    of the Clean Water Act, Hughes River Watershed Conservancy v.
    Glickman, 
    81 F.3d 437
    , 448 (4th Cir. 1996), and the district court’s
    conclusion that it had subject matter jurisdiction over the Common-
    wealth’s enforcement action, In re Celotex Corp., 
    124 F.3d 619
    , 625
    (4th Cir. 1997). We review any factual findings of the district court
    for clear error. Virginia Vermiculite, Ltd. v. Historic Green Springs,
    Inc., 
    307 F.3d 277
    , 284 (4th Cir. 2002).
    III.
    A.
    Before reaching the merits of either case, we must first determine
    whether we have jurisdiction over the Board’s enforcement action
    premised on Virginia law. In cases where state law creates the cause
    of action, federal question jurisdiction is "unavailable unless it
    appears that some substantial, disputed question of federal law is a
    necessary element of one of the well-pleaded state claims." Franchise
    Tax Bd. v. Constr. Laborers Vacation Trust, 
    461 U.S. 1
    , 13 (1983)
    (emphasis added). For a federal issue to be both a necessary and dis-
    puted element, "the vindication of a right under state law [must] nec-
    essarily turn[ ] on some construction of federal law." 
    Id. at 9
    (emphasis added).
    In the present case, the district court noted that both the Virginia
    state statute and the Corps’ federal regulations define "wetlands" as
    "those areas that are inundated or saturated by surface or groundwater
    at a frequency and duration sufficient to support, and that under nor-
    mal circumstances do support, a prevalence of vegetation typically
    adapted for life in saturated soil conditions." 
    33 C.F.R. § 328.3
    (b);
    
    Va. Code Ann. § 62.1-44.3
    . Based on this shared scientific definition,1
    1
    It is, of course, unexceptional that Virginia would elect to take advan-
    tage of the Corps’ vast technical resources in elucidating the scientific
    meaning of "wetlands," while at the same time making its own, unrelated
    decision on when and where to exercise jurisdiction over those wetlands.
    As Henry R. Butler and Jonathan R. Macey have observed:
    TREACY v. NEWDUNN ASSOCIATES                            7
    the district court concluded "that the state statute is coextensive with
    the CWA." In making this finding, however, the district court con-
    fused the definition of "scientific wetlands" and "jurisdictional wet-
    lands."
    Newdunn concedes, and the district court recognized, that at least
    thirty-eight acres of the Newdunn Property contained "wetlands" as
    that term is used in both 
    33 C.F.R. § 328.3
    (b) and 
    Va. Code Ann. § 62.1-44.3
    . Thus, from a scientific perspective, there is no disputed
    federal question as to whether the Newdunn Property contains wet-
    lands.2 Because the resolution of this case in no way turns upon any
    interpretation of 
    33 C.F.R. § 328.3
    (b), there can be no federal ques-
    tion jurisdiction based on Virginia’s decision to adopt the Corps’
    technical definition of wetlands. See Franchise Tax Bd., 461 U.S. at
    One real source of economies of scale associated with central-
    ization of environmental regulation could be in centralized
    research on technical, scientific issues that recur throughout a
    number of different states . . . . These economies can be realized
    by the federal government even when most policy-making and
    implementation functions are handled by the states.
    Henry R. Butler & Jonathan R. Macey, Using Federalism to Improve
    Environmental Policy 26 (1996).
    2
    In fact, even if this case did involve a dispute over the scientific defi-
    nition of wetlands, it is doubtful that the conflict would raise a question
    of federal law. Importantly, the General Assembly did not reference or
    cite to federal law in its definition of wetlands. Rather, it merely parroted
    the language from the federal regulation in 
    Va. Code Ann. § 62.1-44.3
    .
    The fact that a state law might mimic the wording of a federal law, of
    course, does not transform interpretation of the state statute into a federal
    question.
    Many states, for example, have "little NEPAs" on their books, which
    are based on language found in federal law. See Bradley C. Karkkainen,
    "Toward a Smarter NEPA: Monitoring and Managing Government’s
    Environmental Performance," 
    102 Colum. L. Rev. 903
    , 905 (2002) (not-
    ing that the National Environmental Policy Act, 
    42 U.S.C. § 4321
    , et
    seq., "has inspired dozens of ‘little NEPAs’ at the state and local levels").
    Notwithstanding the presence of mirrored language, courts applying
    those statutes are interpreting state, not federal, law.
    8                     TREACY v. NEWDUNN ASSOCIATES
    9. Stated differently, the issue is not whether the Newdunn Property
    contains wetlands, but whether those wetlands are within the jurisdic-
    tion of the State Water Control Board. The answer to this question is
    resolved solely by looking to the Virginia Wetlands Resources Act of
    2000, codified at 
    Va. Code Ann. §§ 62.1-44.3
    , 44.5, 44.15, 44.15:5,
    44.29 (2001).
    The Virginia Act was crafted after this circuit announced its deci-
    sion in United States v. Wilson, 
    133 F.3d 251
     (4th Cir. 1997), and
    after the D.C. Circuit invalidated the Corps’ Tulloch rule, which had
    allowed the Corps to regulate incidental fallback as a pollutant added
    to a wetland, see Nat’l Mining Assoc. v. U.S. Army Corps of Eng’rs,
    
    145 F.3d 1399
    , 1404 (D.C. Cir. 1998). Following Wilson and
    National Mining, and the subsequent loss of federal control over Vir-
    ginia’s wetlands, nearly 10,000 acres of nontidal wetlands were
    drained or were set to be drained in a period of less than six months.
    See Tyler Whitley, "Nontidal Wetlands Rules Bill Expected," Rich-
    mond Times-Dispatch, Dec. 1, 1999, at B4.3 Although Virginia was
    losing wetlands at a dramatic pace, the State Water Control Board
    was largely without authority to act. Interpreting then-existing state
    law, former Attorney General Mark Earley opined, "[T]he Board [did]
    not have authority to regulate wetlands beyond that contemplated by
    the § 401 certification process" found in the CWA. 1999 Op. Va.
    Att’y Gen. 179.
    Subsequent to this 1999 opinion, environmentalists petitioned the
    Virginia General Assembly to fill the regulatory vacuum. Delegate L.
    Preston Bryant, Jr., responded to this call, and co-patroned a bill to
    provide the state with a comprehensive, nontidal wetlands permitting
    program. In a letter to then-Governor James S. Gilmore, III, Delegate
    Bryant explained the need for his proposal as follows:
    For many years, the federal wetlands permitting program
    has fluctuated in its ability to protect Virginia’s nontidal
    wetlands. This fluctuation has resulted not only from chang-
    3
    As Wilson and National Mining make clear, the district court erred
    when it wrongly assumed that, prior to the Supreme Court’s ruling in
    SWANCC, 
    531 U.S. 159
     (2001), the Corps enjoyed "seemingly unlimited
    jurisdiction."
    TREACY v. NEWDUNN ASSOCIATES                           9
    ing administrations and policies within the federal U.S.
    Army Corps of Engineers, but more recently from changing
    federal case law . . . . A comprehensive state program would
    remove the uncertainty created by changing federal policies
    and case law decisions.
    Letter from L. Preston Bryant, Jr., Delegate, to James S. Gilmore, III,
    Governor (Dec. 3, 1999) (quoted in Br. of Amici Curiae Sen. Whip-
    ple, et al. at 19). Delegate Bryant’s bill was ultimately passed into
    law, becoming the Virginia Act at issue in this case. See S. 648, 2000
    Gen. Assem., Reg. Sess. (Va. 2000); H.D. 1170, 2000 Gen. Assem.,
    Reg. Sess. (Va. 2000) (amending 
    Va. Code Ann. §§ 62.1-44.3
    , 44.5,
    44.15, 44.15:5, 44.29). Newdunn posits that the Virginia Act was
    crafted narrowly to close only the Tulloch loophole, and not to
    broaden the Board’s jurisdiction within the Commonwealth. The plain
    text of the Virginia Act, however, belies this contention. Virginia law
    defines "state waters" broadly to include "all water, on the surface and
    under the ground, wholly or partially within or bordering the Com-
    monwealth or within its jurisdiction, including wetlands." 
    Va. Code Ann. § 62.1-44.3
     (emphasis added). The words "including wetlands"
    were added to the statute by the Virginia Act, without any jurisdic-
    tional limitation. S. 648, 2000 Gen. Assem., Reg. Sess. (Va. 2000);
    H.D. 1170, 2000 Gen. Assem., Reg. Sess. (Va. 2000). In "state
    waters," Virginia law prohibits excavating, draining, filling, dumping,
    or any other activity that may significantly alter or degrade a wetland
    without a permit issued by the Board. See 
    Va. Code Ann. § 62.1-44.5
    .
    Nothing in the Virginia Act refers to the CWA’s definition of "navi-
    gable waters" or the "waters of the United States." A plain reading of
    the Virginia Act, therefore, makes it inconceivable that the term "wet-
    lands" as it is used in the state legislation could necessarily turn on
    the resolution of a question of federal law.4
    4
    In fact, if there were any doubt as to the meaning of the text, the legis-
    lative history of the Virginia Act makes it abundantly clear that the legis-
    lation was crafted, not to incorporate the CWA’s jurisdictional limits, but
    rather to remedy perceived shortcomings with the jurisdictional reach of
    federal law.
    During the 2000 General Assembly session, legislators rejected a pro-
    posal that would have limited the Board’s jurisdiction to those wetlands
    10                  TREACY v. NEWDUNN ASSOCIATES
    Alternatively, Newdunn maintains that the Board’s jurisdiction
    depends on a resolution of federal law because 
    Va. Code Ann. § 62.1
    -
    44.15:5 provides: "Issuance of a Virginia Water Protection Permit
    shall constitute the certification required under § 401 of the Clean
    Water Act." Based on this statute, Newdunn posits that the Board’s
    jurisdiction must be coextensive with the Corps’. Newdunn’s theory,
    however, is premised on a fundamental misunderstanding of the rela-
    tionship between the federal and state permitting procedures.
    Section 401(a)(1) of the CWA requires an applicant for a federal
    permit to "provide the licensing or permitting agency a certification
    from the State in which the discharge originates or will originate
    . . . ." The Commonwealth, by enacting § 62.1-44.15:5, has taken
    advantage of this federal provision, so that when federal and state
    laws overlap, applicants may use their state permits to satisfy the cer-
    tification requirements under section 401 of the CWA. Of course,
    simply because a state permit carries the added benefit of satisfying
    a potentially applicable federal requirement does not mean that the
    "that are subject to federal jurisdiction under the federal Clean Water
    Act." See Legislative History of S. 695, Gen Assem. Reg. Sess. (Va.
    2000), available at http://leg1.state.va.us/001/bil.htm; Legislative His-
    tory of H.D. 1246, 2000 Gen. Assem., Reg. Sess. (Va. 2000), available
    at http://leg1.state.va.us/001/bil.htm.
    Instead, lawmakers adopted an initiative that defined "wetlands" with-
    out any federal jurisdictional limitation and that was crafted not only to
    close the Tulloch loophole, but also "to protect and enhance the Com-
    monwealth’s wetland resources" by charging the Board with designing
    regulatory programs "to achieve no net loss of existing wetland acreage
    and functions." See Legislative History of S. 648, Gen Assem. Reg. Sess.
    (Va. 2000), available at http://leg1.state.va.us/001/bil.htm; Legislative

    As one commenter has observed, "Under Virginia’s new wetlands reg-
    ulations, impacts that may have been permissible to isolated wetlands
    under federal regulations will be limited in Virginia. This is because Vir-
    ginia includes wetlands as part of its definition of ‘state waters.’" Lisa

    , 143 (2002).

    state’s jurisdictional reach turns on an interpretation of the CWA.
    Undoubtedly, situations will arise where a permittee needs a state per-
    mit, but no federal permit. In those situations, the state permitting pro-
    cess would apply without reference to the CWA.
    As the Supreme Court of Virginia recognized, "The CWA and fed-
    eral regulations allow a state program to operate a discharge elimina-
    tion system program in place of the federal program, provided that the
    state program is authorized under state law and has standards that are
    at least as stringent as the federal ones." State Water Control Bd. v.
    Smithfield Foods, 
    542 S.E.2d 766
    , 768 (Va. 2001) (emphasis added).
    That is, for a state’s permitting procedure to satisfy the federal
    requirements of 
    33 U.S.C. § 1342
    (a), the state law must be "at least"
    as exacting as the Clean Water Act, but of course, it may be more
    demanding.
    Even when state and federal requirements do overlap, as was the
    case in Smithfield Foods, the issue of whether the Board has authority
    to regulate the subject wetlands remains a question of Virginia law.
    Accordingly, the Board’s jurisdiction cannot "necessarily depend" on
    any interpretation of federal law, even if it happens that federal and
    state laws are coextensive on the particular facts of a certain case. See
    Franchise Tax Bd., 
    461 U.S. at 13
    .
    The Virginia Supreme Court’s finding in Smithfield Foods that "the
    interests and rights of both the [federal and state] entities [we]re
    vested in a single permit" does not alter this analysis. See Smithfield
    Foods, 542 S.E.2d at 770. In Smithfield Foods, because this court had
    already "affirmed the finding of the district court that Smithfield was
    liable," and because the United States Supreme Court denied certio-
    rari, the federal determination was a final judgment for the purposes
    of res judicata. Id. at 768. In the present case, while the Corps and
    the Board may ultimately require Newdunn to obtain the same dis-
    charge permit, no final judgment in either case has been rendered.
    Depending upon how the Corps and Newdunn resolve the federal
    case on remand, the Board’s interest may or may not be satisfied.
    Accordingly, the Board should be permitted to pursue its rights in a
    Virginia court. Of course, if either the state or federal actions were to
    result in a final judgment requiring the issuance of a permit satisfying
    12                  TREACY v. NEWDUNN ASSOCIATES
    both federal and state laws, then Newdunn might elect to file a motion
    to have the unresolved action dismissed on the grounds of res judi-
    cata. See Smithfield Foods, 542 S.E.2d at 771.
    In sum, in light of the Virginia Act’s clear statutory language, it is
    apparent that "Virginia now regulates activities in wetlands beyond its
    federal mandate." Goodwin, Annual Survey of Virginia Law, 37 U.
    Rich. L. Rev. at 141. It would be perverse, therefore, for this court to
    conclude that the jurisdictional limits of the Virginia Act depend upon
    the CWA. Any determination as to the extent of the Board’s jurisdic-
    tional reach is purely a question of state law that does not require the
    resolution of any federal question. Because we lack jurisdiction over
    the Board’s action, we reverse the district court’s ruling on the
    Board’s motion to remand, and we remand the state enforcement
    action to the Virginia court from which it was improperly removed.
    B.
    We now turn to the only case for which federal subject matter juris-
    diction exists — the Corps’ civil enforcement action premised on the
    CWA.
    The Federal Water Pollution Control Amendments of 1972, known
    collectively as the Clean Water Act, were crafted "to restore and
    maintain the chemical, physical, and biological integrity of the
    Nation’s waters." 
    33 U.S.C. § 1251
    (a) (2002). To achieve this ambi-
    tious goal, Congress mandated that "the discharge of any pollutant by
    any person shall be unlawful" except as in compliance with the Act’s
    permitting procedures. 
    Id.
     § 1311. The permitting scheme at issue in
    this case is articulated in section 404(a), which gives the Corps the
    authority "to issue permits . . . for the discharge of dredged or fill
    material into the navigable waters at specified disposal sites." Id.
    § 1344(a). The CWA defines "navigable waters" to include "the
    waters of the United States, including the territorial seas," id.
    § 1362(7), and the Corps’ regulatory jurisdiction is limited by this
    definition.
    In 1985, the Supreme Court ruled that the Corps possessed the
    authority to exercise jurisdiction over wetlands that were adjacent to
    other waters, even though the wetlands themselves were not navigable
    TREACY v. NEWDUNN ASSOCIATES                        13
    waters-in-fact. United States v. Riverside Bayview Homes, Inc., 
    474 U.S. 121
    , 139 (1985). The Court deferred to the Corps’ technical
    expertise on the matter, noting the considerable difficulty, both for the
    Corps and for federal courts, in defining the jurisdictional limits of the
    Act. 
    Id. at 132
    . The Court explained:
    In determining the limits of power to regulate discharges
    under the Act, the Corps must necessarily choose some
    point at which water ends and land begins. Our common
    experience tells us that this is often no easy task: the transi-
    tion from water to solid ground is not necessarily or even
    typically an abrupt one. Rather, between open waters and
    dry land may lie shallows, marshes, mudflats, swamps, bogs
    — in short, a huge array of areas that are not wholly aquatic
    but nevertheless fall far short of being dry land. Where on
    this continuum to find the limit of "waters" is far from obvi-
    ous.
    
    Id.
     The Corps had determined that wetlands adjacent to other waters
    should be included in the definition of "waters of the United States,"
    because "wetlands adjacent to lakes, rivers, streams, and other bodies
    of water may function as integral parts of the aquatic environment
    even when the moisture creating the wetlands does not find its source
    in the adjacent bodies of water." 
    Id. at 134-35
    . The Supreme Court
    upheld the Corps’ exercise of jurisdiction, concluding, "We cannot
    say that the Corps’ conclusion that adjacent wetlands are inseparably
    bound up with the ‘waters’ of the United States — based as it is on
    the Corps’ and the EPA’s technical expertise — is unreasonable." 
    Id. at 134
    .
    The Supreme Court has recently reaffirmed Riverside Bayview
    Homes, commenting: "It was the significant nexus between the wet-
    lands and ‘navigable waters’ that informed our reading of the CWA
    in Riverside Bayview Homes." SWANCC, 
    531 U.S. at 167
    ; see also
    United States v. Krilich, 
    303 F.3d 784
    , 791 (7th Cir. 2002) (observing
    that the SWANCC Court "reaffirm[ed] its prior holding [in Riverside
    Bayview Homes] that Section 404 encompassed non-navigable wet-
    lands adjacent to navigable waters," but "explicitly declined to further
    determine the exact meaning of ‘navigable waters’"). In SWANCC,
    the Court struck down the Corps’ so-called "Migratory Bird Rule,"
    14                  TREACY v. NEWDUNN ASSOCIATES
    which defined "waters of the United States" to include intrastate
    waters, "[w]hich are or would be used as habitat by birds protected
    by Migratory Bird Treaties; or . . . [w]hich are or would be used as
    habitat by other migratory birds which cross state lines . . . ."
    SWANCC, 
    531 U.S. at 164
     (quoting 
    51 Fed. Reg. 41217
    ). Quoting
    Riverside Bayview Homes, the Court held that "Congress’ concern for
    the protection of water quality and aquatic ecosystems indicated its
    intent to regulate wetlands ‘inseparably bound up with the "waters"
    of the United States.’" 
    Id. at 167
     (emphasis added). Thus, the Corps’
    attempted exercise of jurisdiction over isolated ponds that had no
    hydrologic connection whatsoever to navigable waters could not stand.5
    Along similar lines, this court has previously held that the phrase
    "waters of the United States" cannot be used by the Corps to assert
    jurisdiction over intrastate, nonnavigable waters, solely on the ground
    that those waters could possibly affect interstate commerce. United
    States v. Wilson, 
    133 F.3d 251
    ,253-54 (4th Cir. 1997). We explained,
    "[T]o include intrastate waters that have nothing to do with navigable
    or interstate waters, expands the statutory phrase ‘waters of the
    United States’ beyond its definitional limit." 
    Id. at 257-58
     (emphasis
    added). Accordingly, we struck down 
    33 C.F.R. § 328.3
    (a)(3),
    because it attempted to give the Corps jurisdiction over any waters,
    "the use, degradation or destruction of which could affect interstate
    or foreign commerce . . . ." 
    Id. at 257
     (quoting 
    33 C.F.R. § 328.3
    (a)(a)
    (1993)). As we held in Wilson, and as the Supreme Court affirmed in
    SWANCC, the Corps’ jurisdiction does not extend to the limits of the
    5
    As is evident from the above discussion, Newdunn’s insistence that
    SWANCC limited the Corps’ jurisdiction solely to those wetlands adja-
    cent to navigable waters-in-fact is plainly incorrect. Unlike the adminis-
    trative regulation at issue in Riverside Bayview Homes, the "Migratory
    Bird Rule" before the Court in SWANCC was not developed to clarify the
    scientifically nebulous point "at which water ends and land begins." Riv-
    erside Bayview Homes, 
    474 U.S. at 134
    . Instead, the Corps’ supposed
    justification for the rule was purely legal — that Congress drafted the
    CWA with the intention of defining "waters of the United States" as
    broadly as possible under the Commerce Clause. The Court rejected the
    Corps’ interpretation of the CWA, recognizing that the Corps’ Com-
    merce Clause argument would read the phrase "navigable waters" com-
    pletely out of the statute. SWANCC, 
    531 U.S. at 172
    .
    TREACY v. NEWDUNN ASSOCIATES                       15
    Commerce Clause. Rather, the critical, limiting term is ‘navigable
    waters,’ as that term is defined in 
    33 U.S.C. § 1362
    (7).
    In the present case, the Corps asserts jurisdiction over navigable
    waters (
    33 C.F.R. § 328.3
    (a)(1)), tributaries of navigable waters
    (§ 328.3(a)(5)), and "[w]etlands adjacent to waters (other than waters
    that are themselves wetlands) . . ." (§ 328.3(a)(7)). The Corps defines
    "adjacent" to mean, "bordering, contiguous, or neighboring. Wetlands
    separated from other waters of the United States by man-made dikes
    or barriers, natural river berms, beach dunes and the like are ‘adjacent
    wetlands.’" 
    33 C.F.R. § 328.3
    (c). This circuit has recently concluded
    that, pursuant to these regulations, the Corps intends to assert jurisdic-
    tion over "any branch of a tributary system that eventually flows into
    a navigable body of water." United States v. Deaton, 
    332 F.3d 698
    ,
    711 (4th Cir. 2003). In Deaton, the Corps claimed authority to regu-
    late wetlands bordering a "roadside ditch" that took "a winding,
    thirty-two mile path to the Chesapeake Bay." 
    Id. at 702
    . Along the
    way to the Bay, water flowed from the Deaton’s wetlands to the road-
    side ditch, and then into a "culvert" on the other side of the road. 
    Id.
    Water from the culvert drained into a second ditch, which flowed into
    Beaverdam Creek. Beaverdam Creek was "a direct tributary of the
    Wicomico River, which [was] navigable." 
    Id.
     The distance from the
    Deaton’s wetlands to a navigable-in-fact river was approximately
    eight miles. The Deaton court upheld the Corps’ exercise of jurisdic-
    tion over all of these waters, finding that "the Corps’s regulatory
    interpretation of the term ‘waters of the United States’ as encompass-
    ing nonnavigable tributaries of navigable waters does not invoke the
    outer limits of Congress’s power or alter the federal-state frame-
    work." 
    Id. at 708
    . In dismissing a Commerce Clause challenge to the
    Corps’ regulations, the Deaton court summarized Congress’ well-
    articulated purpose for crafting the CWA and concluded, "The Corps
    has pursued this goal by regulating nonnavigable tributaries and their
    adjacent wetlands. This use of delegated authority is well within Con-
    gress’s traditional power over navigable waters." 
    Id. at 707
    . In sum,
    the Corps’ unremarkable interpretation of the term "waters of the
    United States" as including wetlands adjacent to tributaries of naviga-
    ble waters is permissible under the CWA because pollutants added to
    any of these tributaries will inevitably find their way to the very
    waters that Congress has sought to protect.
    16                 TREACY v. NEWDUNN ASSOCIATES
    To the extent that Newdunn challenges the Corps’ decision to label
    the manmade, I-64 ditch a "tributary," that argument has also been
    foreclosed by Deaton. The Deaton court recognized that the Corps
    has defined the word "tributary" to include "the entire tributary sys-
    tem," including roadside ditches. 
    Id. at 710
    . As explained above, Dea-
    ton deferred to the Corps’ definition of "tributary" because
    "discharges into nonnavigable tributaries and adjacent wetlands have
    a substantial effect on water quality in navigable waters." 
    Id. at 712
    .
    That the I-64 ditch at issue in the present case is a manmade rather
    than a natural watercourse is an irrelevant distinction. As the Corps
    has explained:
    The discharge of a pollutant into a waterway generally has
    the same effect downstream whether the waterway is natural
    or manmade. Indeed, given the extensive human modifica-
    tion of watercourses and hydrologic systems throughout the
    country, it would be difficult to identify a principled basis
    in this case for distinguishing between natural watercourses
    and watercourses that are wholly or partly manmade or
    modified.
    (Br. for the United States at 48-49.) This observation is particularly
    meaningful in the present case, where the United States has exten-
    sively documented the connection between the Newdunn Property’s
    wetlands and the navigable waters, both before and after the construc-
    tion of I-64. Because of this longstanding connection, it would be
    illogical to conclude that, prior to the existence of I-64, the Newdunn
    Wetlands would have been within the ambit of the Corps’ regulations,
    but that now, with the construction of the highway, the wetlands are
    no longer jurisdictional.
    As stated before, the CWA’s primary objective is "to restore and
    maintain the chemical, physical, and biological integrity of the
    Nation’s waters." 
    33 U.S.C. § 1251
    (a) (2002). If this court were to
    conclude that the I-64 ditch is not a "tributary" solely because it is
    manmade, the CWA’s chief goal would be subverted. Whether man-
    made or natural, the tributary flows into traditional, navigable waters.
    Accordingly, the Corps may permissibly define that tributary as part
    of the "waters of the United States." See 
    33 U.S.C. § 1362
    (7).
    TREACY v. NEWDUNN ASSOCIATES                      17
    Turning our attention to the specific wetlands at issue in this case,
    it is undisputed that water flows intermittently from wetlands on the
    Newdunn Property through a series of natural and manmade water-
    ways, crossing under I-64, draining into the west arm of Stony Run,
    and eventually finding its way 2.4 miles later to traditional navigable
    waters. As the district court found, Stony Run is "navigable-in-fact"
    because the "lower reaches of Stony Run are subject to the ebb and
    flow of the tide." The court further found that "Stony Run flows into
    the Warwick River, which intersects with the James River, which
    intersects with the Hampton Roads Harbor, which intersects with the
    Chesapeake Bay." These factual findings are supported in part by
    photographic evidence of silt-laden water flowing from the subject
    property into Stony Run. Because there exists a sufficient nexus
    between the Newdunn Wetlands and navigable waters-in-fact, the
    Corps’ jurisdiction in this case is amply supported by the Act and the
    Corps’ regulations under the Act.
    IV.
    For the reasons stated above, the ruling of the district court is
    reversed. We remand the Board’s state enforcement action directly to
    the Virginia state court from which it was improperly removed. We
    remand the Corps’ enforcement action to the district court for further
    proceedings not inconsistent with this opinion.
