    Before BAUER, RIPPLE and KANNE, Circuit Judges.
    RIPPLE, Circuit Judge. After employees of the Indiana
    Department of Natural Resources (“DNR”) drained a
    supply pond into the Fawn River, the plaintiffs, riparian
    landowners, brought this action against DNR employees,
    David Clary, Tom Meyer, Neil Ledet and Gary Armstrong,
    in their individual capacities, and against the Director of the
    2                                                     No. 02-1863
    DNR in his official capacity. The plaintiffs alleged that these
    defendants had violated the Clean Water Act (“CWA”), 33
    U.S.C. § 1251 et seq., and also had violated their rights
    under the Takings and Due Process Clauses of the Constitu-
    tion of the United States. The parties filed cross-motions for
    summary judgment. The district court granted the defen-
    dants’ motion for summary judgment on all claims. For the
    reasons set forth in the following opinion, we reverse the
    judgment of the district court with respect to the CWA
    claim and remand for further proceedings. With respect to
    the takings and due process claims, we affirm the judgment
    1
    of the district court.

    BACKGROUND

    A. Factual Background
    The plaintiffs are riparian landowners along a five-mile
    portion of the Fawn River that begins at Orland Dam and
    ends at Greenfield Millpond. The defendants are an official
    of the DNR and employees of the DNR who work at the
    Fawn River State Fish Hatchery (“Hatchery”) located in
    1
    After oral argument, the court invited the Environmental
    Protection Agency and the United States Army Corps of Engi-
    neers to file a brief as amicus curiae. The Agency and the Corps
    accepted the court’s invitation and filed a brief. The court
    expresses its thanks to both for the assistance that they have
    rendered.
    2
    Because the district court granted summary judgment to the
    defendants, we take the facts as alleged by the plaintiffs to be
    true. See Adusumilli v. City of Chicago, 
    164 F.3d 353
    , 357 (7th Cir.
    1998).

    Orland, Indiana. The Fawn River runs through the Hatchery
    property. As it flows near the Hatchery’s main building, the
    river has been dammed to form a 1.75 acre supply pond.
    This supply pond feeds by gravity the Hatchery’s fish
    rearing ponds. When the main flow control gates on the
    dam are opened, the pond water flows from the supply
    pond down the Fawn River and eventually to Greenfield
    Millpond.
    A bypass channel upstream of the supply pond is used to
    divert the Fawn River before it reaches the supply pond.
    The Fawn River, as it existed below the supply pond prior
    to May 18, 1998, was a clean, clear body of water. The river
    had a gravel bed and was used for swimming, fishing,
    canoeing and other recreational activities. It also was home
    to various plant and aquatic animal habitats. See R.4, Ex.5.
    In 1993, there was discussion in the Town of Orland re-
    garding a “proposed dike . . . and mill pond dredging
    adjacent to the town park.” R.4, Ex.12. “The project [was]
    being proposed to alleviate flooding of the Fawn River into
    the town park.” 
    Id. In a
    letter from a state senator to the
    Orland Town Board, the senator noted the problem with the
    supply pond and stated that “the Fawn River is a highly
    protected environmental river and it may be difficult to
    make any kind of repairs or dredging in that area.” R.4,
    Ex.14. The DNR supported the project, stating in a June 18,
    1993 letter that the supply pond had built up silt for more
    than 12 years, and, as a result, it was not navigable “even in
    a canoe.” R.4, Ex.12. The DNR stated also that “[a]quatic
    vegetation ha[d] taken over the supply pond” and that the
    DNR would “submit[] a work plan this summer to control
    the vegetation using approved chemicals.” 
    Id. In that
    same
    letter, the DNR noted that “[s]uch a work plan will tie in
    4                                                No. 02-1863
    3
    nicely with the town’s project.” 
    Id. In 1994
    and 1995, the
    DNR applied chemicals, destroying much of the plant life in
    the supply pond. After having destroyed the vegetation, the
    DNR noted that the pond was “now navigable, by canoe, for
    the first time in over a decade.” R.4, Ex.10.
    In 1996, defendants David Clary, the Property Manager
    for the Hatchery, and Tom Meyer, the Assistant Property
    Manager for the Hatchery, noticed a problem with the main
    flow control structure of the dam. The flow control structure
    consisted of six separate gates. The gates were made of
    horizontal wooden slats that were stacked in two rows and
    slotted into four vertical metal I-beams. Some of the I-beams
    appeared to be rusting. On March 31, 1997, Mr. Clary
    consulted a local welder, who observed that repairs to the
    I-beams were needed. Mr. Clary sent a project proposal and
    budget for the repairs to Gary Armstrong, Hatcheries
    Supervisor, on April 16, 1997. This proposal specifically
    made reference to draining the supply pond in order to
    complete the repair, but stated that the repair “would have
    to be completed during a time of low water flow.” R.93,
    Ex.21 at 2. Also, in the memo attached to this proposal, Mr.
    Clary asked: “Will we need to get a permit for the dam
    repair work?” 
    Id. at 1.
    When Mr. Clary was asked during his
    deposition whether he ever had received an answer to this
    question, he replied: “I don’t think we ever received an
    answer on that. . . . I have no documentation of an answer
    from [Gary Armstrong].” R.93, Ex.16 at 64. Funding ap-
    proval for the repairs was obtained on October 23, 1997.
    Later, on March 12, 1998, Mr. Clary discovered a problem
    with the river intake plumbing, specifically, the pump was
    3
    The “town’s project” was the proposed dredging of the supply
    pond and construction of the dike. See R.4, Ex.12.
    No. 02-1863                                                      5
    not holding its prime. The pump is used to run water into
    the Hatchery and rearing ponds and is critical to Hatchery
    operations. After trying various small repairs, Mr. Clary and
    Mr. Meyer concluded that the plumbing in the river inlet
    structure needed to be exposed in order to make the plumb-
    ing repairs. The Hatchery needed the pump system to be
    working properly by June 1, 1998, for the Walleye harvest-
    ing.
    On May 18, 1998, Mr. Meyer and Mr. Clary decided to
    draw-down the water in the supply pond to make the
    plumbing repairs, to allow visual inspection of the gates and
    to have a test draw-down for the future repairs that were to
    be done to the gates. Mr. Armstrong, their supervisor, was
    aware of the plans to open the dam and lower the supply
    pond. However, Mr. Clary stated in his deposition that
    initially they had not intended to drain fully the supply
    pond. Mr. Clary also said that they had not intended to
    “fully inspect the dam gates down to the bottom.” R.93,
    Ex.16 at 23. In fact, Mr. Clary stated that, in determining
    how low to draw down the supply pond, their “intentions
    4
    were only to expose the piping.” 
    Id. at 67.
      At approximately 8:30 a.m., Mr. Clary and Mr. Meyer
    began the draw-down process by raising the upper three
    gates of the main flow control structure. After waiting for
    4
    The plaintiffs take issue with Mr. Meyer’s and Mr. Clary’s
    explanations that the purpose of opening the dam was to make
    repairs to the pump. The plaintiffs point to evidence in the record
    that, prior to the incident, the defendants were aware that it was
    possible to drain the supply pond more slowly to avoid the
    release of mud and sediment into the Fawn River. See, e.g., R.93,
    Ex.1 at 197-99, 205 (deposition of Mr. Meyer) (conceding that “we
    probably could have done it [drained the supply pond] slower
    than we did”).

    several minutes, the water level in the supply pond stabi-
    lized, although there was still a considerable amount of
    5
    water flowing over the top of the three lower gates.
    Mr. Clary and Mr. Meyer then proceeded to open one of the
    three bottom gates. After several attempts and much
    difficulty because of the water rushing over the top of the
    gate, they succeeded in raising the gate a few inches. They
    then continued to raise the gate incrementally until the
    bottom of the gate was above the level of the water exiting
    the supply pond. By 11:00 a.m., the supply pond was
    drained to the point that the pipes and plumbing work were
    exposed and all that remained of the pond was a meander-
    ing channel of water cut into the floor of the supply pond
    flowing toward the open gates. Leaving the gates open, Mr.
    Clary and Mr. Meyer took a lunch break, made a visit to a
    rock dam upstream of the supply pond, traveled to the east
    unit of the hatchery to observe water levels, worked on a list
    of materials needed for the plumbing repairs and then
    traveled separately to purchase repair parts and plumbing
    supplies.
    Mr. Meyer was first to return to the dam from his errand
    and was met at approximately 2:00 p.m. by defendant Mr.
    Ledet, a DNR Fisheries Biologist. Standing next to the open
    gate, Mr. Ledet noticed that “the water level in the supply
    pond had been lowered to a distinct channel exposing the
    silt-covered bottom. . . . Water flowing through this channel
    was picking up silt and transporting it through the flow
    control gate.” R.80 ¶ 5. Mr. Meyer testified that Mr. Ledet
    remarked to him that the water flowing through the gate
    “looked awful damn muddy.” R.93, Ex.1 at 200.
    5
    Mr. Meyer admitted that the water flow on the supply pond
    was not low on May 18, 1998; instead he recollected “a normal
    flow type of condition, neither high nor low.” R.93, Ex.1 at 69.
    No. 02-1863                                                     7
    The two men were standing next to the open gate dis-
    cussing the project when plaintiff Gene Lewis arrived;
    he was visibly upset. Mr. Lewis pointed out that muck and
    sediment were being flushed out of the supply pond,
    through the open dam and into the river, and he requested
    that the gates to the dam immediately be closed. The men
    refused to comply with Mr. Lewis’ request, and, shortly
    thereafter, Mr. Ledet returned to his office located on
    Hatchery property.
    Larry Koza, a DNR assistant Fisheries Biologist, who also
    maintained an office on Hatchery property, stated in his
    deposition that “when I looked out and I saw the water,
    it was . . . black. It . . . apparently had a high silt load in
    it from eroding a channel into the bottom” of the supply
    pond. R.93, Ex.23 at 45. Concerned about the sediment being
    flushed into the river and the adverse effect it could have on
    the fish populations downstream, Koza and Mr. Ledet
    decided to drive together upstream to the water control
    structure of the bypass channel. Upon arrival, the men
    opened completely the partially open water control struc-
    ture “to divert as much clean water into the river below the
    dam as possible, bypassing the hatchery [supply pond].”

    R.80 ¶ 7.
    6
    In his deposition, when asked why, upon seeing the black
    water flowing through the dam, he quickly attempted to increase
    the amount of clean water in the river, Larry Koza responded:
    Well, you hate to see a lot [of] heavy, you know, dark colored
    sediment laden, whatever you call it, water going down the
    stream. And if that has to happen, then you want to make
    sure that you have as much fresh water, you know, coming
    into there. My—you know, my first thought was for [the] fish
    population to make sure that you were getting as much clean
    water through as you could.

    Meanwhile, around 2:15 p.m., Mr. Clary returned from his
    errand to the site of the dam. Simultaneously, Attorney Neal
    Lewis, son of Gene Lewis and counsel for the plaintiffs,
    arrived on the scene. Attorney Lewis demanded that the
    gate be shut immediately, but Mr. Meyer and Mr. Clary
    informed him that they were working on some repairs to the
    pump and would shut the gate as soon as the repairs were
    finished. However, after a short discussion concerning the
    day’s events, Mr. Meyer and Mr. Clary decided to shut the
    gate without making the repairs. Around 3:00 p.m., Mr.
    Meyer informed Mr. Lewis that the bottom gate had just
    been lowered. Shortly thereafter the three top gates were
    also lowered. By 4:00 p.m., most of the supply pond had
    7
    been refilled. See R.76 ¶ 12; see also R.77 ¶¶ 18-19.
    The record contains extensive evidence regarding the
    appearance and substance of the water that flowed through
    the bottom gate on May 18, 1998. Mr. Clary stated in his
    deposition that the water coming out of the bottom gate was
    “somewhat muddy,” R.84, Ex.2 at 43; Mr. Meyer stated in
    his deposition that the water “was a muddy color im-
    mediately upon raising the bottom gate” and that “it was
    muddy throughout that draining operation, muddy col-

    R.93, Ex.23 at 45.
    7
    Whether the supply pond was refilled completely on the
    afternoon of May 18, 1998, seems to be in dispute. Dr. Daniel
    Willard personally inspected the supply pond on May 22, 1998,
    and he noted that the supply pond “showed that it had recently
    been drawn down considerably.” R.9, Ex.2 at 20. Additionally,
    photographs taken on May 24, 1998, by plaintiffs Gene and
    Sharon Lewis show that water still was collecting in the channel
    cut on March 18, 1998, and that the upper supply pond had not
    refilled to its former banks. See R.84, Ex.10D.
    No. 02-1863                                                       9
    ored,” R.84, Ex.3 at 139; and Mr. Ledet stated in his deposi-
    tion that the water coming through the dam “was very dark.
    It had picked up a lot of—or whatever a lot is—it had
    picked up, you know, bottom muck, sediment material,”
    8
    R.84, Ex.4 at 61.
    Similarly, the plaintiffs submitted extensive evidence
    detailing the effects of the released sediment on the Fawn
    8
    The defendants themselves offered conflicting testimony con-
    cerning the water that came out of the gates and the effects on the
    river below. In contrast to the statements recounted in the text,
    the defendants made statements indicating that the water clarity
    was “unremarkable.” See, e.g., R.77 ¶¶ 19-20. Mr. Clary, for
    example, stated in his affidavit that, at about 5:00 p.m. on May 18,
    1998, he traveled to the County Road 1100 East bridge that
    overlooked part of the river and from there the river appeared
    “normal and I could see the stream bottom.” R.76 ¶ 13. Mr. Ledet
    made a similar statement that he went to the County Road 1100
    East bridge and “[t]he water clarity and level at this bridge
    crossing were normal. The water was not unusually turbid or
    discolored with silt.” R.80 ¶ 9. Additionally, Mr. Meyer noted
    that the water coming out of the bottom gate was “discolored”;
    and that after closing the gates he “observed a thin layer of silt
    and discolored water” downstream, but, from the County Road
    1100 East bridge, “water clarity was unremarkable and [he]
    observed no dead or distressed fish.” R.77 ¶¶ 19-20. The power
    of these statements is diminished by Mr. Clary’s explanation in
    his deposition that, when he went to the bridge and saw “no
    indication [of] silt or sediment,” that he knew that the silt or
    sediment cut from the dam “would have to have been” mostly
    discharged (at that time) somewhere between the County Road
    1100 East bridge and the dam. See R.84, Ex.2 at 167. Mr. Clary’s
    deposition statement makes it clear that he knew that the silt and
    deposit had to be somewhere above the County Road 1100 East
    bridge and below the dam. Thus, the fact that the river color and
    flow was unremarkable at County Road 1100 did not indicate to
    him that the river was free from silt or other deposits.

    River. Gene Lewis testified that he personally witnessed
    mud flowing through the open dam. He stated:
    While the DNR was cutting out the bottom of their im-
    poundment by having opened fully their dam structure,
    I entered the river immediately below the spillway
    structure of the DNR dam where I was standing in a
    semi-solid flow of mud which had the consistency of
    loose cooked oatmeal and looked like chocolate-brown
    pudding. I could feel this semi-solid flow of mud to
    approximately my knees—about 2 feet deep. On top of
    this flowing river of mud was a layer of very murky
    water in a liquid state.
    R.84, Ex.10 at ¶ 8. Mr. Lewis also presented photographs of
    himself standing in the mud below the dam. Specifically the
    photographs show him holding up black mud that was
    flowing from his feet to his knees. See R.84, Ex.10A. Mr.
    Lewis also took photographs of sections of the supply pond
    after the channel had been cut through it; these photographs
    show the water flowing through the channel with the
    exposed black-mud floor on both sides. See 
    id. He later
    had
    photographs taken of himself standing in and measuring the
    mud deposits in the Fawn River after the opening of the
    dam; these deposits ranged in depth from a few inches to
    two feet. See R.84, Ex.10C.
    Plaintiffs also submitted expert testimony by professors at
    Indiana University who performed in-depth analyses of the
    river and the mud deposits therein after the dam had been
    opened. Dr. Michael Zaleha’s study demonstrated that the
    sediment in the river above the dam is different from the
    mud that now exists in the river below it and that the
    physical and chemical characteristics of the mud deposits in
    the Fawn River are not typical of river muds; he also opined
    that these deposits were caused by a rapid flow of a water
    No. 02-1863                                               11
    and mud mixture (40%-80% concentrated) resulting from
    the opening of the dam. He further noted that he personally
    had observed “the large volume of mud deposits” which
    extend for several miles now on the Fawn River. R.84, Ex.7
    at 15. John Gasper, a professional engineer, performed
    studies to determine the amount of mud deposited by the
    flow into the Fawn River. He concluded that “approxi-
    mately one hundred thousand cubic yards of unconsoli-
    dated material were discharged and deposited into the
    lower reaches of the Fawn River”; this amount was gener-
    ated from between 10,000 and 33,000 cubic yards of consoli-
    dated material that was dredged from the supply pond.
    R.84, Ex.8 ¶ 6. Gasper stated that, had the vegetation not
    been killed in 1994 and 1995, the amount of sediment cut
    out of the supply pond would have been significantly less.
    He also stated that these deposits
    have elevated the bottom of Fawn River, are impairing
    the flow and circulation of those waters and are reduc-
    ing the pre-event reach of the waters. In addition, cer-
    tain areas of the channel that were once flowing are
    currently stagnant and other areas of quiet waters have
    been significantly filled with mud.
    R.84, Ex.8 ¶ 7.
    Dr. Daniel Willard, a professor of environmental sciences,
    reached a similar conclusion after conducting a study on the
    effects of the draw-down that occurred on May 18, 1998. Dr.
    Willard stated:
    The volume of reservoir sediments released from [the
    supply pond] is estimated to have occupied a channel of
    20 feet wide, 5,000 feet long and average 5 feet thick (8
    feet near the dam and 2 feet 5,000 feet upstream from
    the dam). This represents a volume of 500,000 cubic feet
    of reservoir sediment.

    R.84, Ex.9B at 14. Dr. Willard also stated:
    I have further observed the condition of the small lake
    at Greenfield Mills, Indiana prior to May 18, 1998, and it
    has under gone a substantial and extraordinary trans-
    formation since the events of May 18, 1998. What was
    once a mostly [] open water shallow lake environment
    is now an emergent wetland environment dominated by
    marshy conditions as a result of massive deposits of
    sedimentation from the events of May 18, 1998.
    9
    R.84, Ex.9 ¶ 12. Dr. Willard’s report also contains extensive
    research into the adverse effects of the mud on the Fawn
    River plant and animal life. Specifically, the report contains
    his own eyewitness account of the fish kill that occurred as
    a result of the release of mud into the river:
    At several points along the way large numbers of dead
    fishes were laid out on the bank. . . . These fishes
    included many species with notably large Northern and
    Walleye, plus Smallmouth, suckers, carp, and a variety
    of other fishes. Several of these fishes showed gills
    covered with muck on examination. I saw several,
    hundred, dead fishes total.

    Plaintiffs also placed into the record affidavits and photographs
    regarding the substantial deposits of mud into Greenfield
    Millpond. The affidavits demonstrate that the Greenfield
    Millpond, which is located approximately five miles downstream
    from the Orland Dam, was converted from a primarily open
    water environment before May 18, 1998, to a primarily vegetative
    environment after the dam was opened. See R.84, Ex.12 ¶4,
    Exs.12A-12B.

    The defendants do not dispute with affidavits or
    other evidence any of the expert or lay testimony brought
    by the plaintiffs showing that massive amounts of sediment
    were deposited into the river or onto the plaintiffs’
    11
    property.
    Mr. Meyer stated in his deposition that he and Mr. Clary
    made no repairs to the plumbing on May 18, 1998. He also
    stated that the repairs on the plumbing that had been
    planned for May 18, 1998, were actually accomplished a few
    weeks later. The actual repairs were accomplished without
    drawing-down, lowering or draining the supply pond. Mr.
    Clary noted that a DNR diver completed the plumbing

    This observation was corroborated by several other documents
    in the record. For example, Gene Lewis stated in an affidavit that
    he found ninety-four dead fish the day after the opening of the
    dam and has observed the death or disappearance of many fresh
    water mussels and snails. See R.84, Ex.10 ¶¶10, 23. Indeed, the
    DNR acknowledged the fish kill. See R.4, Ex.8.
    11
    In fact, the defendants’ own evidence supports the plaintiffs’
    theory that the water cut a channel through the floor and that the
    displaced sediment went into the Fawn River. Mr. Clary stated in
    his deposition that the water coming out of the dam became
    “somewhat muddy after the pond was drained and it was cutting
    the channel as it went through the pond bottom.” R.84, Ex.2 at 43.
    He went on to explain that, although he “didn’t make any
    measurements” he would guess that the “meandering” channel
    was “anywhere from one to three feet” deep. 
    Id. at 44.
    Mr. Ledet,
    upon arrival at the supply pond, noticed that “the water level in
    the supply pond had been lowered to a distinct channel exposing
    the silt covered bottom. Water flowing through this channel was
    picking up silt and transporting it through the flow control gate.”
    R.80 ¶5. Thus, according to the defendants’ evidence, the force of
    the water flowing out of the dam cut a channel into the floor of
    the supply pond.

    repair in less than three hours. See R.93, Ex.16 at 21. With
    respect to the repair to the dam gates, DNR Structural
    Engineer Larry Wayland suggested three different alterna-
    tive repair scenarios, none of which required a rapid
    draining of the supply pond. Two alternatives involved
    using a coffer dam to retain the water in the pond while the
    repairs were being performed; these options did not require
    the supply pond to be drained at all. Indeed, the repair
    eventually was accomplished using such a device.
    According to the defendants, the only repair work that
    Mr. Meyer and Mr. Clary accomplished on May 18, 1998,
    was attaching a chain to two of the lower gates. Mr. Meyer
    admitted, however, that this attachment was not really a
    “repair”; he explained that the action “was kind of an af-
    terthought” taken as a result of the difficulty they experi-
    enced raising the three lower gates. R.93, Ex.1 at 221.
    B. District Court Proceedings
    The plaintiffs brought this action against Mr. Clary, Mr.
    Meyer, Mr. Ledet and Mr. Armstrong, in their individual
    capacities, and against the Director of the DNR in his official
    capacity. They alleged that the defendants had violated §
    402 and § 404 of the CWA, 33 U.S.C. §§ 1342 and 1344,
    respectively, by failing to obtain a permit prior to draining
    the supply pond. The plaintiffs also pursued two constitu-
    tional claims: They claimed that the deposit of mud on their
    property constituted an illegal taking by the State and that
    draining the supply pond without prior notice and hearing
    violated their due process rights. The defendants moved for
    summary judgment on all of these claims, and the plaintiffs
    filed a cross-motion for summary judgment on the § 404
    claim.
    The district court granted summary judgment to the
    defendants on all grounds and denied the plaintiffs’ cross-
    No. 02-1863                                                      15
    motion for summary judgment. Turning first to the § 404
    claim, the district court determined that the hydraulic
    dredging or sluicing that occurred on May 18, 1998, came
    within the prohibition of dredging without a permit. How-
    ever, it further determined that the dredging fell within the
    maintenance exception to the permit requirement set forth
    in 33 U.S.C. § 1344(f)(1)(b). In doing so, the court rejected
    the plaintiffs’ argument that the defendants’ actions could
    not constitute maintenance under the applicable regulation
    because, according to the regulation, “maintenance does not
    include any modification that changes the character, scope,
    or size of the original fill design . . . .” 33 C.F.R. § 323.4(a)(2).
    According to the district court, “original fill design” referred
    to the supply pond, and there was no evidence that the size
    or depth of the supply pond was altered by the draw-down.
    The district court also determined that the defendants’
    actions did not fall within the “recapture” provision, 33
    U.S.C. § 1344(f)(2). That section provides:
    Any discharge of dredged or fill material into the navi-
    gable waters incidental to any activity having as its
    purpose bringing an area of the navigable waters into a
    use to which it was not previously subject, where the
    flow or circulation of navigable waters may be impaired
    or the reach of such waters be reduced, shall be required
    to have a permit under this section.
    33 U.S.C. § 1344(f)(2). The district court held that the
    purpose of the May 18, 1998 draw-down was to perform
    maintenance and not to “ ‘bring[] an area of the navigable
    waters into a use to which it was not previously subject.’ ”
    R.131 at 22-23 (quoting § 1344(f)(2)). Consequently, the
    defendants’ actions were not “recaptured” by § 1344(f)(2),
    and a permit was not required.
    With respect to the § 402 permit claim, the district court
    found that the sediments dredged from the supply pond
    16                                                No. 02-1863
    were pollutants under recent CWA case law. However, the
    court stated, the plaintiffs’ § 402 claim failed nonetheless
    because “[a]ny ‘churning’ or movement of the soil or sedi-
    ment in this case was entirely incidental to a maintenance
    activity that had no purpose of excavating and redepositing
    soil downstream.” R.131 at 29.
    The court then turned to the constitutional claims. With
    respect to the takings claim, the district court acknowledged
    that a physical invasion usually constitutes a taking.
    Nevertheless, the district court held that the plaintiffs’ claim
    should be dismissed because the plaintiffs had not brought
    an action in state court for inverse condemnation and,
    therefore, had failed to exhaust their state remedies
    as required by Williamson County Regional Planning
    Commission v. Hamilton Bank of Johnson City, 
    473 U.S. 172
    (1985). With respect to the procedural due process claim, the
    district court held that the plaintiffs had failed to come
    forward with any evidence that the defendants had the
    requisite intent to deprive the plaintiffs of their property—
    a requirement of a due process violation. Alternatively,
    the district court stated that, “even if the acts alleged were
    intentional as Plaintiffs allege, this does not violate due pro-
    cess so long as adequate state post-deprivation remedies are
    available,” and “Plaintiffs[’] brief altogether fail[ed] to
    address why state post-deprivation remedies were inade-
    quate nor d[id] they set forth any legal analysis on this
    point.” R.131 at 36.
    II
    DISCUSSION
    A. Standard of Review
    “We review the grant of summary judgment de novo.”
    Harley-Davidson Motor Co. v. PowerSports, Inc., 
    319 F.3d 973
    ,
    No. 02-1863                                                     17
    980 (7th Cir. 2003). Summary judgment is appropriate if,
    viewing the facts in the light most favorable to the non-
    moving party, there is no genuine issue of material fact, and
    the moving party is entitled to judgment as a matter of law.
    See 
    id. B. The
    Clean Water Act Statutory Scheme
    The CWA makes the “discharge of any pollutant” into
    12               13
    navigable waters, by any person unlawful, absent com-
    pliance with specific provisions of the Act. See 33 U.S.C.
    §§ 1311(a), 1362(7), 1362(12). Two of those provisions are
    § 1342 (§ 402) and § 1344 (§ 404), which create permitting
    systems for the discharge of pollutants. Generally, in order
    to avoid liability under the CWA, a defendant who wishes
    to discharge a pollutant must first obtain a permit either
    under § 1344 (a § 404 permit) for the discharge of dredged
    or fill material or under § 1342 (a § 402 permit) for other
    pollutants. Because the plaintiffs allege that the defendants
    discharged dredged materials into the Fawn River, the
    question of whether a permit is required is answered by
    14
    reference to § 404.
    12
    “Navigable waters,” is defined as the “waters of the United
    States,” 33 U.S.C. § 1362(7). The parties do not dispute that the
    Fawn River, an interstate river, falls within “waters of the United
    States.” See Appellants’ Br. at 21 n.14.
    13
    “Person” is defined to include a “State, municipality, commis-
    sion, or political subdivision of a state.” 33 U.S.C. § 1362(5).
    14
    The district court and the parties discussed CWA liability on
    the part of the defendants in terms of both § 402 and § 404.
    However, § 404 is the permitting scheme that regulates dis-
    charges of dredge and fill material, which is the category of dis-
    (continued...)
    18                                                   No. 02-1863
    (...continued)
    charge at issue here, and thus is the permitting scheme relevant
    to this case. If a defendant falls within an exception to the
    permitting requirements of § 404 under § 1344(f)(1), as argued
    here, then the defendant is not liable under § 1311 for having
    “discharged a pollutant” or subject to the § 1342 (§ 402) permit-
    ting requirements. See 33 U.S.C. § 1344(f)(1) (explaining that the
    exemptions for obtaining a § 404 permit for the discharge of
    dredge and fill material also exempt the discharge from regula-
    tion under §§ 1311 or 1342). As explained in the amicus brief of
    the Environmental Protection Agency and the Army Corps of
    Engineers (collectively “amici”),
    [t]he discharge of pollutants other than dredged or fill
    material are generally regulated under section 402, which
    creates the EPA-administered National Pollutant Discharge
    Elimination System [“NPDES”] permitting program. See 33
    U.S.C. § 1342. Discharges of dredged or fill material are
    generally regulated under section 404, which creates the
    Corps-administered dredge-and-fill permitting program. 33
    U.S.C. § 1344.
    The discharges in this case fall within the purview of the
    section 404 program. . . .
    Amicus Br. at 4-5. This distinction is also made clear in the reg-
    ulations implementing § 1342. See 40 C.F.R. § 122.1(a)(1). (“The
    regulatory provisions contained in this part and parts 123, and
    124 of this chapter implement the National Pollutant Discharge
    Elimination System (NPDES) Program under section 318, 402,
    and 405 of the Clean Water Act . . . .”). According to the regula-
    tions, “[t]he following discharges do not require NPDES permits:
    . . . (b) Discharges of dredged or fill material into waters of the
    United States which are regulated under section 404 of the
    CWA.” 40 C.F.R. § 122.3(b).
    We note in passing that the regulations implementing § 404
    set forth certain exceptions to the definition of “discharge of
    (continued...)
    No. 02-1863                                                       19
    (...continued)
    dredged material” including “[d]ischarges of pollutants into
    waters of the United States resulting from the onshore subse-
    quent processing of dredged material that is extracted for any
    commercial use (other than fill).” 33 C.F.R. § 323.2(d)(3)(i). “These
    discharges,” the regulations explain, “are subject to section 402 of
    the Clean Water Act even though the extraction and deposit of
    such material may require a permit from the Corps or applicable
    state Section 404 program.” 
    Id. However, such
    materials are not
    at issue in the present case, and § 404 is the only permitting
    process applicable here. Consequently, we affirm that portion of
    the district court’s judgment holding that the defendants were
    not required to obtain a § 402 permit for their actions on May 18,
    1998, but on the ground set forth above.
    Nevertheless, we note our disagreement with the district
    court’s conclusion that the defendants’ purpose and intent were
    relevant in determining whether § 402 had been violated. See
    R.131 at 29 (stating that the defendants were not liable under
    § 402 because they “had no purpose of excavating and redeposit-
    ing soil downstream”). Liability for discharging a pollutant
    without a § 402 permit and absent an exemption is strict; a de-
    fendant’s intent or purpose is irrelevant. See Kelly v. EPA, 
    203 F.3d 519
    , 522 (7th Cir. 2000) (citing cases).
    20                                                     No. 02-1863
    1. Section 404 Permit Requirement
    The CWA generally prohibits “the discharge of any pol-
    lutant by any person” absent compliance with one of the
    permitting schemes set forth in the Act. 33 U.S.C. § 1311(a).
    The Act defines “discharge of pollutant[s]” to mean “any
    addition of any pollutant to navigable waters from any
    point source.” 33 U.S.C. § 1362(12). Under the CWA,
    pollutant includes “dredged spoil, solid waste, . . . biological
    materials, . . . rock, sand . . . .” 33 U.S.C. § 1362(6). Here, the
    plaintiffs maintain that the DNR employees made an
    15
    addition of “dredged spoil,” namely the materials emptied
    from the supply pond, into the Fawn River from a point
    16
    source, the Orland Dam.
    15
    In the district court, the parties disputed whether “dredged”
    materials included materials that had been hydraulically dredged
    or “sluiced”; however, the defendants do not urge any such
    distinction in this court.
    16
    The CWA defines a point source as
    any discernable, confined and discrete conveyance, including
    but not limited to any pipe, ditch, channel, tunnel, conduit,
    well, discrete fissure, container, rolling stock, concentrated
    animal feeding operation, or vessel or other floating craft,
    from which pollutants are or may be discharged.
    33 U.S.C. § 1362(14). We noted in Froebel v. Meyer, 
    217 F.3d 928
    (7th Cir. 2000), that several other circuits had addressed the issue
    whether a dam could be considered a point source and that “all
    have concluded that, at least under some circumstances, a dam
    can meet the statutory definition of point source.” 
    Id. at 937.
    Although we were not required to resolve the issue in Froebel
    (continued...)
    No. 02-1863                                                       21
    The defendants argue on appeal that there was no “addi-
    tion” of dredged spoil to the Fawn River because the supply
    pond and the Fawn River constitute the same body of water.
    In support of their position, they point to National Wildlife
    Federation v. Gorsuch, 
    693 F.2d 156
    , 174-75 (D.C. Cir. 1982),
    and National Wildlife Federation v. Consumers Power Co., 
    862 F.2d 580
    , 584 (6th Cir. 1988), which hold that the discharge
    of pollutants from one body of water to a contiguous one is
    not an “addition” because it does not add a pollutant from
    the outside world.
    More recent cases, however, have undercut severely the
    holdings of Gorsuch and Consumers Power. For example,
    the Fourth Circuit in United States v. Deaton, 
    209 F.3d 331
    (4th Cir. 2000), held that “sidecasting” (digging dirt from a
    ditch and casting it onto the contiguous wetland) was still
    an “addition” of a pollutant even though nothing was
    “added” from the outside world. The court stated:
    Once it was removed, that material became “dredged
    (...continued)
    (because the dam largely had been removed), we stated that “the
    CWA’s definition of ‘point source’ . . . connotes the terminal end
    of an artificial system for moving water, waste, or other materi-
    als.” 
    Id. at 938.
    We also noted that “[t]he broad reach of ‘naviga-
    ble waters’ pushes the natural reading of ‘point source’ back to
    the point at which an artificial mechanism introduces a pollut-
    ant.” 
    Id. Here, the
    artificial mechanism of the dam was used to
    convey pollutants into the Fawn River, a navigable waterway.
    Consequently, we believe that the dam constitutes a “point
    source.” See Catskill Mountains Chapter of Trout Unltd., Inc. v. City
    of New York, 
    273 F.3d 481
    , 493 (2d Cir. 2001) (noting that “point
    source” refers to “the proximate source from which the pollutant
    is directly introduced to the destination water body,” giving the
    example of a pipe).

    spoil,” a statutory pollutant and a type of material that
    up until then was not present on the Deaton property.
    It is of no consequence that what is now dredged spoil
    was previously present on the same property in the less
    threatening form of dirt and vegetation in an undis-
    turbed state. What is important is that once that mate-
    rial was excavated from the wetland, its redeposit in
    that same wetland added a pollutant where none had
    been before.
    
    Id. at 335;
    see also Avoyelles Sportsmen’s League, Inc. v. Marsh,
    
    715 F.2d 897
    , 923-24 & n.43 (5th Cir. 1983) (noting that term
    “addition” may reasonably be understood to include “rede-
    posit,” that “ ‘dredged’ material is by definition material
    that comes from the water itself,” and that “[a] requirement
    that all pollutants must come from outside sources would
    effectively remove the dredge-and-fill provision from the
    statute”); Borden Ranch P’ship v. United States Army Corps of
    Eng’rs, 
    261 F.3d 810
    , 814 (9th Cir. 2001).
    The rationale for limiting the holdings of Gorsuch and
    Consumers Power to the very circumscribed facts upon which
    they were based and to employ a broader definition of
    addition was well stated by the Second Circuit in Catskill
    Mountains Chapter of Trout Unlimited, Inc. v. City of New York,
    
    273 F.3d 481
    , 489-94 (2d Cir. 2001). The Second Circuit noted
    that the decisions of the courts in Gorsuch and Consumers
    Power were based on deference to the EPA’s interpretation
    of “addition.” The Second Circuit continued:
    If the EPA’s position had been adopted in a rulemaking
    or other formal proceeding, deference of the sort ap-
    plied by the Gorsuch and Consumers Power courts might
    be appropriate. Instead, the EPA’s position is based on
    a series of informal policy statements made and consis-
    tent litigation positions taken by the EPA over the years,
    primarily in the 1970s and 1980s. Recent Supreme Court
    No. 02-1863                                                 23
    cases emphasize that such agency statements do not
    deserve broad deference of the sort accorded by the
    Gorsuch and Consumers Power courts. See United States v.
    Mead Corp., 
    533 U.S. 218
    (2001); Christensen v. Harris
    County, 
    529 U.S. 576
    (2000).
    
    Id. at 490
    (parallel citations omitted). The court then held
    that the narrow definition of addition simply could not be
    applied to the facts before it:
    The present case, however, strains past the breaking
    point the assumption of “sameness” made by the
    Gorsuch and Consumers Power courts. Here, water is
    artificially diverted from its natural course and travels
    several miles from the Reservoir through Sandaken
    Tunnel to Esopus Creek, a body of water utterly unre-
    lated in any relevant sense to the Schoharie Reservoir
    and its watershed. . . . When the water and the sus-
    pended sediment therein passes from the Tunnel into
    the Creek, an “addition” of a “pollutant” from a “point
    source” has been made to a “navigable water,” and
    terms of the statute are satisfied.
    
    Id. at 492.
      Unlike the position espoused by the EPA in Gorsuch
    and Consumers Power, here the EPA, participating at the
    court’s invitation as an amicus curiae, has urged upon this
    court the broader definition of “addition” employed by the
    courts in the more recent § 404 cases. See Amicus Br. at 5
    (stating that “the courts of appeals have consistently rec-
    ognized that materials that have been scooped up and then
    redeposited in the same waterbody can result in a discharge
    of a pollutant” and citing, inter alia, Avoyelles Sportsmen’s
    League and Borden Ranch). The EPA’s position, which
    follows the holdings of recent circuit cases, is persuasive for
    several reasons. First, such a reading is compatible with the
    24                                                    No. 02-1863
    purpose of the CWA to “restore and maintain the chemical,
    physical and biological integrity of the Nation’s waters.” 33
    U.S.C. § 1251(a). Second, it is logical to believe that soil and
    vegetation removed from one part of a wetland or waterway
    and deposited in another could disturb the ecological
    balance of the affected areas—both the area from which the
    material was removed and the area on which the material
    was deposited. Finally, we agree with our colleagues on the
    Fifth Circuit that excluding such dredged materials from the
    concept of “addition” “would effectively remove the
    dredge-and-fill provision from the statute.” 
    Avoyelles, 715 F.2d at 924
    n.43. We therefore follow the interpretation of
    the amici and of our sister circuits and hold that the dis-
    charge of dredged material, such as that removed from the
    supply pond, into a contiguous body of water or wetland,
    here the Fawn River, constitutes an “addition” of dredged
    17
    spoil under the statute.
    The defendants’ actions of May 18, 1998, therefore, con-
    stituted an addition of dredged spoil into the Fawn River
    and were subject to the permit requirement of § 404. In
    order to escape liability under the CWA, the defendants
    therefore must establish that their actions fall into one of the
    narrow exemptions to the permit requirements.
    2. Maintenance Exception
    17
    The amici note that the situation in National Wildlife Federation
    v. Gorsuch, 
    693 F.2d 156
    (D.C. Cir. 1982), and National Wildlife
    Federation v. Consumers Power Co., 
    862 F.2d 580
    (6th Cir. 1988),
    concerned normal dam operations that resulted in changes to
    water quality. Here, by contrast, the sediment had settled out of
    the navigable waters, and the DNR’s opening of the flow
    structure control gates dredged those materials from their resting

    Section 1344(f)(1) provides an exemption to the federal
    permit requirements “for narrowly defined activities spe-
    cifically identified in paragraphs A-F that cause little or
    no adverse effects either individually or cumulatively.”
    Envtl. Policy Div. of the Cong. Research Serv. for the Senate
    Comm. on Envtl. and Pub. Works, 95th Cong., 3 A Legislative
    History of the Clean Water Act of 1977, 420 (Comm. Print 1978)
    (hereinafter “Legislative History”). For these specified
    activities, a discharge of dredged or fill material “is not
    prohibited by or otherwise subject to regulation under this
    section or section 1311(a) or 1342 of this title [except 1317 of
    the CWA].” 33 U.S.C. § 1344(f)(1).
    In order to be exempt from the § 404 permit requirement,
    however, a party must show not only that it is exempt un-
    der one of the provisions in § 1344(f)(1), it also must show
    that its activities do not fall within the “recapture” provi-
    sion, § 1344(f)(2). “Read together the two parts of Section
    404(f) provide a narrow exemption for . . . activities that
    have little or no adverse effect on the waters of the U.S.”
    United States v. Brace, 
    41 F.3d 117
    , 124 (3d Cir. 1994). The
    defendants bear the burden of establishing both that they
    qualify for one of the exemptions of § 1344(f)(1) and that
    18
    their actions are not recaptured by § 1344(f)(2).
    Turning first to the exemptions, the defendants maintain
    that their actions fall within the maintenance exemption
    set forth at § 1344(f)(1)(B). Paragraph (B) of § 1344(f)(1)
    exempts the discharge of dredged or fill material “for the
    purpose of maintenance, including emergency reconstruc-
    18
    Amici construe the recapture provision as containing two dis-
    tinct elements: that the activity (1) has “ ‘as its purpose bringing
    an area of the navigable waters into a use to which it was not
    previously subject,’ and (2) has the consequence of impairing the
    flow or circulation of navigable waters or reducing the reach of
    such waters.” Amicus Br. at 8.

    tion of recently damaged parts, of currently serviceable
    structures such as dikes, dams, levees, groins, riprap,
    breakwaters, causeways, and bridge abutments or ap-
    proaches, and transportation structures.” 33 U.S.C.
    § 1344(f)(1)(B). The regulations provide that “[m]aintenance
    does not include any modification that changes the charac-
    ter, scope, or size of the original fill design.” 33 C.F.R. §
    323.4(a)(2). We have construed § 1344(f)(1) narrowly
    because “Congress intended that Section 1344(f)(1) exempt
    from the permit process only ‘narrowly defined activities .
    . . that cause little or no adverse effects either individually
    or cumulatively [and which do not] convert more extensive
    areas of water into dry land or impede circulation or reduce
    the reach and size of the water body.’ ” United States v.
    Huebner, 
    752 F.2d 1235
    , 1240-41 (7th Cir. 1985) (quoting 3
    Legislative History 420).
    The plaintiffs contend that the defendants do not fall
    within the exemption under § 1344(f)(1) for the follow-
    ing reasons: (1) There is a genuine issue of material fact
    regarding whether the defendant’s actual purpose in drain-
    ing the supply pond was “maintenance” or merely a pretext
    for dredging the pond without a permit; (2) The exemption
    does not include dredging that was not reasonably neces-
    sary or at least proportional to the maintenance performed;
    and (3) The dredging of the pond was not maintenance
    because it impermissibly modified “the character, scope, or
    size of the original fill design.” 33 C.F.R. § 323.4(a)(2). We
    consider each of these in turn.
    a. pretext
    The plaintiffs first argue that the district court erred in
    granting summary judgment to the defendants because
    there is a genuine issue of material fact with respect to
    whether the defendants actually raised the gate to perform
    No. 02-1863                                                 27
    maintenance on the dam or whether the “maintenance” was
    just a pretext to dredge the pond without a permit.
    In determining the “purpose” of the defendants’ actions,
    “reviewing courts have consistently looked beyond the
    stated or subjective intentions and determined the effect or
    ‘objective’ purpose of the activity conducted.” United States
    v. Sargent County Water Res., 
    876 F. Supp. 1090
    , 1101 (D.N.D.
    1994) (“Sargent County II”) (reviewing cases and noting that
    in those cases “[a]lthough each of the defendants stated a
    purpose facially worthy of an exemption, it was clear by
    their actions that the only ‘purpose’ each had was to
    circumvent the Act”). In Sargent County II, for example, the
    county’s stated purpose was to remove accumulated silt
    from an existing ditch. In evaluating whether that stated
    purpose was the county’s true purpose, the court observed:
    “Rather than approach the project haphazardly, it hired an
    engineer to determine the original depth, and it hired and
    directed a reputable contractor to perform clean-out mainte-
    nance work only. . . . The court has previously noted that the
    stated purpose [of maintenance] was confirmed by the actions of
    those who performed work on the drain.” 
    Id. (emphasis added).
    The court found that the defendants’ activities of
    removing silt from a ditch fell within the § 1344(f)(1)
    exemption for “maintenance of drainage ditches,” noting
    that the defendants’ actions “were consistent with the stated
    intention of maintaining the drain.” 
    Id. at 1099.
      Based on the record before us, we cannot reach the same
    conclusion with respect to the defendants’ actions. The
    defendants were slow to repair, performed quite “haphaz-
    ardly,” and let the supply pond drain substantially farther
    (and for much longer) than was needed to do the repairs. By
    11:00 a.m. on May 18, 1998, the supply pond was drained to
    a level where the pump was exposed and the lower gate
    was open such that the defendants could inspect the gate.
    28                                                No. 02-1863
    However, the defendants allowed the gate to remain open
    for four more hours; during this time, the defendants had
    lunch, purchased supplies and examined other areas of the
    hatchery. At the end of the day, the defendants had not
    repaired, or even attempted to repair, the pump. The
    defendants also have not brought forth evidence explaining
    the importance or necessity of a test draw-down to the
    subsequent repair of the gates. Finally, the plaintiffs submit-
    ted evidence that the DNR had expressed an interest in
    dredging the supply pond in the years prior to the draw-
    down and had been informed that obtaining a permit for
    this action would be difficult. Viewing the evidence in the
    light most favorable to the plaintiffs, and primarily noting
    the length of time during which the bottom gate was open
    and the pump was exposed without any attempt at making
    repairs, we hold that the plaintiffs have brought forth
    sufficient evidence to create a genuine issue of material fact
    with respect to the defendants’ purpose in drawing down
    the water in the supply pond. On the basis of the record
    before us, a reasonable finder of fact could conclude that the
    purpose of drawing down the water in the supply pond was
    not to perform maintenance on either the pump or the dam,
    but rather was to dredge the supply pond without a permit.
    b. necessity of dredging to maintenance
    The plaintiffs argue that, in order for a dredging activity
    to fall within the maintenance exception, the dredging also
    must be reasonably necessary to the proposed maintenance.
    The EPA and the Army Corps of Engineers, as well, con-
    strue the maintenance exemption to carry a requirement of
    reasonable necessity. They state that the DNR’s activities are
    exempt as maintenance if the “draw-down and discharge of
    sediment was necessary to perform those maintenance
    functions.” Amicus Br. at 7. For the following reasons, we
    No. 02-1863                                                       29
    believe that the amici’s position—that the maintenance
    exemption carries with it a requirement that discharge of
    dredged material be reasonably necessary to the mainte-
    nance—is persuasive.
    We note initially that a requirement of reasonable neces-
    sity or proportionality comports with the legislative history
    of the statute. Throughout the legislative history, Congress
    repeatedly stressed that the § 1344(f)(1) exemptions were
    intended to cover only a very narrow class of exemptions
    for activities “that cause little or no adverse effects either
    19
    individually or cumulatively.” 3 Legislative History 420.
    19
    See also 3 Legislative History 283 (“These specified activities
    should have no serious adverse impact on water quality if per-
    formed in a manner which will not impair the flow and circula-
    tion patterns and the chemical and biological characteristics of
    the affected waterbody and which will not reduce the reach of the
    affected waterbody.” (H.R. Rep. No. 95-830, at 99 (1977)); 
    id. at 421
    (“A case-by-case permit review would not be required for
    narrowly defined activities that cause little or no adverse effects
    either individually or cumulatively, including those activities
    narrowly defined in 404(f)(1)(A-F).”); 
    id. at 474
    (“Federal permits
    will not be required for those narrowly defined activities that
    cause little or no adverse effects either individually or cumula-
    tively” even though “it is understood that some of these activities
    may necessarily result in incidental filling and minor harm to
    aquatic resources . . . .” (emphasis added)); 
    id. at 529
    (noting that
    the § 1344(f)(1) exemptions “exclude[] from permit requirements,
    discharges of dredged or fill material in conjunction with the
    following activities that will cause little or no adverse effects
    either individually or cumulatively”); 4 Legislative History 870
    (recognizing that the § 1344(f)(1) exemptions were intended “to
    free from the threat of regulation those kinds of manmade activities
    which are sufficiently de minimus as to merit general attention at
    State and local level and little or no attention at the national

    Certainly there would be no guarantee against more than de
    minimus adverse effects on the environment if the discharge
    of dredged material was not required to be reasonably
    necessary or otherwise proportional to the maintenance
    performed.
    Additionally, several courts have spoken of § 1344(f)(1)
    exemptions as containing a reasonableness requirement. In
    Sargent County 
    II, 876 F. Supp. at 1098
    , the district court
    determined that the defendants’ activities of removing silt
    from a ditch fell within the § 1344(f)(1) exemption for
    “maintenance of drainage ditches,” particularly where “the
    individuals involved in the clean-out of Drain 11 were
    competent and acted responsibly in carrying out their as-
    signed tasks.” 
    Id. (emphasis added).
    Additionally, in United
    States v. Zanger, 
    767 F. Supp. 1030
    , 1035 (N.D. Cal. 1991), the
    court found that defendants who graded, filled and changed
    the bottom elevation of a stream could not be exempt under
    the maintenance exemption because the exemption “is
    limited to ‘maintenance’ of certain ‘structures,’ ” and there
    were no structures involved. The court further explained
    that “even if there had been [structures], defendants’ filling
    goes far beyond any reasonable definition of maintenance or
    20
    repair.” 
    Id. (emphasis added).
    (...continued)
    level” (emphasis added)); 
    id. at 912
    (stating that the § 1344(f)(1)
    exemptions “should have only a minor impact on water quality
    if performed in a manner that will not impair the flow and
    circulation patterns and the chemical and biological characteris-
    tics of the affected waterbody, and that will not reduce the reach
    of the affected waterbody”).
    20
    The regulations also imply a requirement of reasonableness for
    the maintenance provision at least in the circumstance of
    (continued...)
    No. 02-1863                                                31
    Accordingly, we agree with the plaintiffs and amici that,
    in light of the legislative history, existing case law and the
    rule that the § 1344(f)(1) exemptions must be narrowly con-
    strued, see 
    Huebner, 752 F.2d at 1240-41
    , the maintenance
    exemption should be construed so that only dredging that
    is reasonably necessary to the proposed maintenance is
    exempt from the permit requirement.
    Applying this standard to the case at hand, we believe
    that the plaintiffs have brought forth sufficient evidence to
    permit the trier of fact to conclude that the dredging of the
    pond was not reasonably necessary to either the mainte-
    nance of the pump or the alleged inspection of the gates.
    DNR engineers explained that the repairs could have been
    performed without a rapid draw-down, and in fact, both of
    the alleged repairs were later performed without any draw-
    down of the pond. Moreover, even if the repairs warranted
    a rapid draw-down and dredging of the pond, the pond was
    drained sufficiently to expose the plumbing by 11:00 a.m.,
    and the bottom gate was fully open for inspection by the
    same time. However, the defendants kept the gates open,
    allowed the pond to continue “dredging” until 3:00 p.m.
    and never commenced the necessary repairs. Looking at the
    evidence in the light most favorable to the plaintiffs, we
    cannot say that the dredging of the pond—particularly from
    11:00 a.m. to 3:00 p.m.—was, as a matter of law, reasonably
    necessary to the proposed maintenance.
    (...continued)
    emergency reconstruction of recently damaged parts. The reg-
    ulations only exempt emergency reconstruction that “occur[s]
    within a reasonable period of time after damage occurs.” 33
    C.F.R. § 323.4(a)(2).
    32                                                 No. 02-1863
    c. character, scope, size of the original fill design
    The regulations provide that “[m]aintenance does not in-
    clude any modification that changes the character, scope, or
    size of the original fill design.” 33 C.F.R. § 323.4(a)(2). The
    district court determined that the defendants’ activities did
    not change the original fill design of the supply pond, and,
    therefore, the regulation was not implicated.
    The district court, the parties and amici propose three
    alternative definitions of “original fill design.” The plaintiffs
    argue that “original fill design” refers to the area where the
    dredged material is deposited, here the Fawn River. The
    defendants argue, and the district court held, that original
    fill design is comprised of the dam and the supply pond
    behind the dam. Amici argue that original fill design “refers
    to the manmade structures that are the subject of the
    exemption (e.g. dikes, dams, levees) rather than a natural
    watercourse such as the Fawn River.” Amicus Br. at 8 n.7.
    We are persuaded that the definition of “original fill
    design” suggested by the amici best comports with the
    language of the statutory exemption itself, which speaks to
    the maintenance of “structures.” 33 U.S.C. § 1344(f)(1). The
    only “structure” involved in the proposed maintenance is
    the dam; neither the supply pond nor the Fawn River is a
    man-made “structure” similar to those listed in the statute.
    Our decision to adopt the amici’s position is consistent
    with United States v. Sargent County, 
    876 F. Supp. 1081
    , 1087
    (D.N.D. 1992) (“Sargent County I”), one of the only decisions
    to address the issue. Sargent County I concerned the applica-
    tion of an analogous maintenance exemption for drainage
    ditches, § 1344(f)(1)(C). In that case, the court defined
    original fill design as “1) the depth and width of the ditch as
    it was originally constructed, plus 2) any improvements
    made to any segments of the ditch prior to the CWA’s
    No. 02-1863                                                   33
    jurisdiction over wetlands in 1975.” 
    Id. (emphasis added).
    The drainage ditch in Sargent County was man-made,
    constructed in 1917, and cut through three sloughs before
    draining into a river. See Sargent County 
    II, 876 F. Supp. at 1092
    . In holding that maintenance could not include
    deepening or widening the ditch, the court in Sargent County
    I looked only for changes in the man-made ditch; the court
    did not examine whether the activities deepened or wid-
    ened the sloughs or river or other natural watercourses
    affected by the drainage ditch. Therefore, because it follows
    the statutory language and comports with existing case law,
    we find persuasive the position of the amici with respect to
    21
    the definition of “fill design.”
    Applying this definition to the facts before us, we must
    conclude that, in drawing down the supply pond, the DNR
    employees did not “change[] the character, scope, or size of
    the original fill design” in violation of 33 C.F.R. § 323.4(2).
    There is no evidence to suggest that the draw-down affected
    the character, scope or size of the dam—the only man-made
    “structure” at issue.
    We note that this holding does not compel the conclu-
    sion that the DNR activities constituted maintenance. As we
    have discussed previously, the plaintiffs have brought forth
    sufficient evidence to create a genuine issue of material fact
    as to pretext and as to the reasonable necessity of the
    dredging to the alleged maintenance.
    3. The Recapture Provision
    21
    We also note that “an agency’s considered interpretation of its
    own regulation is entitled to deference ‘when the language of the
    regulation is ambiguous.’ ” Old Ben Coal Co. v. Dir., Office of
    Workers’ Comp. Programs, 
    292 F.3d 533
    , 542 n.8 (7th Cir. 2002).
    34                                                 No. 02-1863
    As we noted earlier, in order to escape the permit re-
    quirements of § 1344, in addition to establishing that their
    actions fall within one of the exemptions of § 1344(f)(1), the
    defendants also must establish that their actions are not
    “recaptured” by § 1344(f)(2). The recapture provision pro-
    vides that, regardless of § 1344(f)(1),
    [a]ny discharge of dredged or fill material into the
    navigable waters incidental to any activity having as its
    purpose bringing an area of the navigable waters into a
    use to which it was not previously subject, where the
    flow or circulation of navigable waters may be impaired
    or the reach of such waters be reduced, shall be required
    to have a permit under this section.
    33 U.S.C. § 1344(f)(2).
    a. statutory construction
    Our interpretation of § 1344(f)(2) must be guided by well-
    established principles of statutory interpretation:
    When we interpret a statute, we look first to its lan-
    guage. If that language is plain, our only function is “ ‘to
    enforce it according to its terms.’ ” United States v. Ron
    Pair Enters., Inc., 
    489 U.S. 235
    , 241 (1989) (quoting
    Caminetti v. United States, 
    242 U.S. 470
    , 485 (1917)).
    The plain meaning of a statute is conclusive unless
    “ ‘literal application of a statute will produce a result
    demonstrably at odds with the intentions of its drafters.’ ”
    Ron 
    Pair, 489 U.S. at 242
    (quoting Griffin v. Oceanic
    Contractors, 
    458 U.S. 564
    , 571 (1982)). Therefore, our
    interpretation is guided not just by a single sentence or
    sentence fragment, but by the language of the whole
    law, and its object and policy. Further, we may adopt a
    restricted rather than a literal meaning of a word where
    No. 02-1863                                                       35
    acceptance of the literal meaning would lead to absurd
    results.
    United States v. Balint, 
    201 F.3d 928
    , 932 (7th Cir. 2000)
    (citations and parallel citations omitted).
    Here our analysis is straightforward. Looking to the lan-
    guage of § 1344(f)(2), the discharge of dredge or fill materi-
    als into navigable waterways is “recaptured” and subject to
    the permitting requirement when two conditions are met: 1)
    the discharge is “incidental to any activity having as its
    purpose bringing an area of the navigable waters into a use
    to which it was not previously subject”; and 2) “the flow or
    circulation of navigable waters may be impaired or the
    reach of such waters be reduced” by the discharge. These
    two requirements are not set forth in the alternative but in
    the conjunctive; consequently, the recapture provision is
    applicable only when both of these conditions are present.
    The courts that have considered the recapture provision
    similarly have concluded that it applies only when both
    22
    conditions have been fulfilled. The case law’s interpreta

    See Amicus Br. at 8 (stating that § 1334(f)(2) recaptures an
    “otherwise exempt” activity “only if that activity (a) has ‘as its
    purpose bringing an area of the navigable waters into a use to
    which it was not previously subject,’ and (b) has the consequence
    of impairing the flow or circulation of navigable waters or
    reducing the reach of such waters”).

    In a Regulatory Guidance Letter from the EPA and the Army
    Corps of Engineers concerning whether “Deep-Ripping” activi-
    ties were recaptured under § 1344(f)(2), the recapture provision
    was construed as requiring a permit “for those otherwise exempt
    discharges which: a. convert an area of the waters of the U.S. to
    a new use, and b. impair the flow or circulation of the waters of
    the U.S. or reduce the reach of waters of the U.S.” Regulatory

    Similarly, in a published memo from the EPA and Army Corps
    of Engineers, the recapture provision was construed as containing
    “a two part test” that requires recapture when both of the

    In sum, the plain language of the statute establishes that
    the recapture provision requires a two-part showing: 1) that
    the dredging activity had as its purpose “bringing an area
    of the navigable waters into a use to which it was not
    previously subject,” and 2) that the dredging activity caused
    the flow or circulation of navigable waters to be impaired or
    the reach of such waters to be reduced. This interpretation
    is bolstered both by case law and by the considered judg-
    ment of the interpreting agencies. Consequently, if the
    defendants can establish as a matter of law either that their
    purpose was not to “bring[] any areas of navigable waters
    into a use to which it was not previously subject” or that the
    activity did not impair the flow or reduce the reach of
    navigable waters, their actions are not “recaptured” by §
    25
    1344(f)(2).

    We do not believe that a two-pronged approach runs contrary
    to our holding in United States v. Huebner, 
    752 F.2d 1235
    (7th
    Cir. 1985). In that case, the plaintiffs had plowed and removed
    wetland vegetation from three reservoirs for “the immediate
    planting of barley [and] for the future planting of corn and other
    dryland crops,” had “used backhoes to clean and deepen existing
    ditches,” had “used a dragline to excavate an approximately 400
    foot long new ditch,” had drained wetlands, had “sidecast
    materials onto the wetlands,” had “used bulldozers to spread the

    discharge over several acres,” had built roads, and had expanded
    the existing cranberry beds. 
    Id. at 1241-43.
    It was clear that the
    plaintiffs’ overall intention was to convert wetlands into uplands
    for the cultivation of dryland crops and to expand their existing
    cranberry beds into wetlands that previously had not been used
    for cultivating wetland crops. The plaintiffs in Huebner attempted
    to use the § 1344(f)(1)(C) exemption for the “construction or
    maintenance of . . . irrigation ditches” to exempt their ditching
    and draining activities. Although we did not specifically restate
    the requirement of § 1344(f)(2) of a “purpose [to] bring[] an area
    of the navigable waters into a use to which it was not previously
    subject,” it was clear that the purpose of the activities described
    in Huebner was to bring wetlands into a new use. Thus the “new
    use” requirement was not at issue; all we needed to analyze was
    whether or not the second requirement of impairing the flow or
    circulation had been met. Thus the fact that in Huebner we only
    discussed the second requirement of the recapture provision does
    not indicate that the first requirement does not exist. As another
    court has noted, in Huebner, we “did not address the previous use
    issue with respect to the ditches because the project as a whole
    clearly went far beyond any prior use, as the . . . facts [in Huebner]
    amply demonstrate.” United States v. Stearns, CIV. No. 3-89-0616,
    
    1990 WL 606673
    at *3 (D. Minn. 1990). Even more importantly,
    however, “[t]o cite Huebner for the proposition that any discharge
    of dredged material onto a wetland requires a permit under the
    recapture clause is to read the previous use language out of the
    recapture clause.” 
    Id. We agree
    that to read Huebner as requiring
    only a showing of a resulting impairment in the flow or reduction
    of the circulation of waters would read the language requiring a
    showing of a “purpose [of] bringing an area of the navigable
    waters into a use to which it was not previously subject” out of
    the recapture provision. 33 U.S.C. § 1344(f)(2).
    No. 02-1863                                                 39
    We now must examine whether the defendants have es-
    tablished that the recapture provision does not apply to
    their actions of May 18, 1998.
    We look first to whether the facts, construed in the light
    most favorable to the plaintiffs, establish that the defen-
    dants’ purpose was other than “bringing an area of naviga-
    ble waters” into a new use. Nevertheless, as we have just
    determined, the recapture provision has two components
    and showing merely effects will not serve as a substitute for
    a finding of a purpose to bring about a new use.
    Although “[c]ommon sense dictates that, under normal
    conditions, ordinary maintenance would not subject an area
    to ‘a use to which it was not previously subject,’ ” Sargent
    County 
    I, 876 F. Supp. at 1088
    (quoting 33 U.S.C.
    § 1344(f)(2)), many of the defendants’ actions were inconsis-
    tent with their stated purpose of performing maintenance.
    After they drew down the water to expose the pipes and the
    dam, they did not engage in the proposed repairs immedi-
    ately, but took a lunch break, drove to purchase supplies,
    and, indeed, never accomplished the proposed repairs on
    that day. Furthermore, there was evidence in the record
    that, prior to May 18, 1998, the defendants had expressed
    interest in dredging the supply pond. Given these facts, we
    do not believe that the defendants have established that
    their purpose was maintenance. Based on this evidence, a
    reasonable finder of fact could conclude that the defendants’
    maintenance explanation was merely a pretext. Thus, we
    cannot say that, as a matter of law, the defendants have
    established that they escape the first prong of the recapture
    provision.
    With respect to the “effects” prong of the recapture anal-
    ysis, viewing the evidence in the light most favorable to the
    plaintiffs, the record before us would permit the trier of fact
    to conclude that the defendants’ actions of May 18, 1998,
    40                                                    No. 02-1863
    impaired the flow and circulation of the Fawn River. The
    plaintiffs’ evidence, set forth in some detail above, showed
    that the river bottom of the Fawn River had been elevated
    by 100,000 cubic yards of unconsolidated sediment that had
    been deposited in the river, thus altering the flow of the
    river. Specifically, one of the plaintiffs’ studies showed that
    release of mud and silt into the Fawn River on May 18, 1998,
    “elevated the bottom of Fawn River, . . . impair[ed] the flow
    and circulation of those waters and . . . reduc[ed] the pre-
    event reach of the waters. In addition, certain areas of the
    channel that were once flowing are currently stagnant and
    other areas of quiet waters have been significantly filled
    with mud.” R.84, Ex.8 ¶ 7. As well, the sediment traveled
    into Greenfield Millpond and transformed that area from a
    shallow lake to a marshland. Dr. Willard observed that
    “[w]hat was once a mostly . . . open water shallow lake
    environment is now an emergent wetland environment
    dominated by marshy conditions as a result of massive
    deposits of sedimentation from the events of May 18, 1998.”
    R.84, Ex.9 ¶ 12. Given the evidence in the record to show
    that the deposit of dredged materials into the Fawn River
    altered the flow of that navigable waterway, the defendants’
    actions also permit the conclusion that the requirements of
    the second prong of the recapture provision have been
    26
    met.
    26
    Several courts have recognized the importance of examining
    the effects of the activity in determining the defendants’ “pur-
    pose.” See United States v. County of Stearns, 
    1990 WL 606673
    , at *4
    (D. Minn. Oct. 2, 1990) (stating that “the effect of the project must
    be considered where a[n] [] entity’s ‘purpose’ is analyzed” and
    that “the ‘purpose’ question is closely related to the extent of
    wetlands likely to be lost”); United States v. Akers, 
    785 F.2d 814
    ,
    822 (9th Cir. 1986) (“It is thus the substantiality of the impact on
    (continued...)
    No. 02-1863                                                       41
    We therefore conclude that, viewing the facts in the light
    most favorable to the plaintiffs, a trier of fact could conclude
    reasonably that the defendants’ actions in draining the
    supply pond on March 18, 1998, fall within the recapture
    provision and are subject to the § 404 permit requirement.
    C. Takings Claim
    The district court noted that, under Loretto v. Teleprompter
    Manhattan CATV Corp., 
    458 U.S. 419
    (1982):
    When faced with a constitutional challenge to a perma-
    nent physical occupation of real property, this Court has
    invariably found a taking. As early as 1872, in Pumpelly
    v. Green Bay Co., 13 Wall. (80 U.S.) 166, 
    20 L. Ed. 557
    ,
    this Court held . . . . that “where real estate is actually
    invaded by superinduced additions of water, earth,
    sand, or other material, or by having any artificial
    structure placed on it, so as to effectually destroy or
    impair its usefulness, it is a taking, within the meaning
    of the Constitution.” 
    Id., 13 Wall.
    (80 U.S.) at 181.
    
    Id. at 427;
    see R.131 at 30. Nevertheless, the district court
    27
    (without discussing the issue of permanence) held that the

    (f)(2).”); United States v. Cumberland Farms, 
    647 F. Supp. 1166
    , 1176
    (D. Mass. 1986) (same). Although not essential to our holding
    today, we believe that a trier of fact would be entitled to consider
    and to give some weight to the effect of the defendants’ actions
    in determining the purpose of their activity.
    27
    The plaintiffs brought forth expert testimony that the deposits
    were at least semi-permanent, but no actual finding on this point

    plaintiffs’ taking claim was barred because the plaintiffs had
    failed to first bring an inverse condemnation suit in Indiana
    state court. See R.131 at 32.
    In Williamson County Regional Planning Commission
    v. Hamilton Bank of Johnson City, 
    473 U.S. 172
    , 186-87 (1985),
    the Supreme Court “articulated a special ripeness doc-
    trine for constitutional property rights claims.” Forseth v.
    Vill. of Sussex, 
    199 F.3d 363
    , 368, 372 (7th Cir. 2000). Under
    Williamson County, federal courts are barred from adjudicat-
    ing takings claims until the plaintiff has satisfied two re-
    quirements, namely, “(1) the ‘Final Decision Requirement’:
    the plaintiff must demonstrate that he or she received a
    ‘final decision’ from the relevant government entity”; and
    “(2) the ‘Exhaustion Requirement’: the plaintiff must have
    sought ‘compensation through the procedures the States has
    provided for doing so.’ ” 
    Forseth, 199 F.3d at 372
    (quoting
    Williamson 
    County, 473 U.S. at 186-87
    , 194). We have subject
    matter jurisdiction over only those takings claims for which
    the Williamson County requirements are satisfied or other-
    wise excused. See 
    Forseth, 199 F.3d at 368
    .
    Takings involving physical invasions—such as the taking
    alleged here—are subject to a more streamlined inquiry. We
    have held that a physical invasion constitutes a “final
    decision” and thus satisfies Williamson County’s first re-
    quirement. Therefore, this type of “takings claim is subject
    only to Williamson’s exhaustion requirement.” 
    Forseth, 199 F.3d at 372
    n.12; see also Wisconsin Cent. Ltd. v. Pub. Serv.
    (...continued)
    was made. See R.84, Ex.9 ¶ 14 (noting that clearing of the deposits
    by the river itself will take decades if it ever occurs). Because we
    agree with the district court that the plaintiffs’ takings claim is
    barred by the plaintiffs’ failure to exhaust state remedies, we do
    not reach the question of permanence.

    a physical takings case, as in a regulatory takings case, the
    property owner must have sought compensation for the alleged
    taking through available state procedures.”), cert. denied,

    The plaintiffs argue that they do not have a remedy in
    state court and should be excused from the exhaustion
    requirement. Specifically, the plaintiffs point to recent
    Indiana case law which states that “an action for inverse
    condemnation is premature until such time as the land-
    owner can establish that there are not available avenues by
    which the landowner can put his property to an economi-
    cally beneficial or productive use.” Galbraith v. Planning
    Dep’t of Anderson, 
    627 N.E.2d 850
    , 854 (Ind. Ct. App. 1994);
    see also Mendenhall v. City of Indianapolis, 
    717 N.E.2d 1218
    ,
    1227-28 (Ind. Ct. App. 1999). Because the plaintiffs still have
    some “economically beneficial or productive use” of their
    property, they maintain that they have no remedy under
    state law and that their position is akin to the plaintiffs in
    Daniels, for whom we excused the exhaustion requirement.
    We cannot accept this submission.
    In 
    Daniels, 306 F.3d at 456
    , the plaintiffs were seeking only
    injunctive relief. However, Indiana law was clear that
    “equitable relief is generally unavailable as a matter of law
    where an action for compensation can be brought subse-
    quent to the taking.” Indiana Dep’t of Transp. v. S. Bells, Inc.,
    
    723 N.E.2d 432
    , 434 (Ind. Ct. App. 2000). Furthermore, the
    Indiana courts explicitly had held that the State did not rec-
    ognize equitable relief for the alleged taking that occurred
    in Daniels, and the plaintiffs in Daniels had not suffered any
    29
    compensable injury. Thus, in Daniels, we held that “with
    29
    Here, it appears from the plaintiffs’ complaint that they seek
    primarily damages, but also a “permanent injunction” against the
    defendants that would “prohibit[] any future lowering of the
    reservoir/freshwater lake waters without prior notice and
    adequate process to protect the Plaintiffs and the river from
    harm.” R.1 at 25-26. Whether or not this injunction would be
    (continued...)
    No. 02-1863                                                         45
    no monetary loss and injunctive relief not an available
    option under [Indiana law], the inverse condemnation
    procedure is inadequate to address the [plaintiffs’] injury,”
    and, consequently, “this futility exempts them from the
    exhaustion requirement.” 
    Daniels, 306 F.3d at 457
    .
    However, Indiana courts have not constructed an absolute
    bar to state actions for physical-invasion takings such as
    that alleged in the present case. In spite of the all-encom-
    passing statements made in Mendenhall and Galbraith, other
    Indiana cases indicate that Indiana in fact does recognize an
    inverse condemnation claim for a physical invasion of
    property, no matter how small that invasion. A brief over-
    view of Indiana inverse condemnation law is instructive.
    Under Indiana state law, there are two stages in any ac-
    tion for inverse condemnation. First, “the landowner must
    show that he has an interest in land which has been taken
    (...continued)
    warranted as a matter of law, the plaintiffs’ complaint does not
    tie specifically the prayer for injunctive relief to the takings claim.
    See 
    id. The plaintiffs
    pray primarily for damages. See 
    id. Thus this
    case is not like Daniels v. Area Plan Commission of Allen County, 
    306 F.3d 445
    (7th Cir. 2002), where the plaintiffs sought exclusively
    equitable relief and had suffered no compensable damages.
    Moreover, in their submissions to this court, the plaintiffs have
    argued only that they were not required to exhaust state remedies
    because Indiana allegedly does not recognize physical invasion
    takings. They did not argue that they were seeking injunctive
    relief and thus had no remedy under Indiana law. Thus we
    analyze the plaintiffs’ takings claim as one for damages, and
    conclude that Indiana provides monetary relief for takings in the
    form of a suit for inverse condemnation. See 
    Daniels, 306 F.3d at 456
    (noting that Indiana provides an inverse condemnation action
    “to recover the value of the property which has been taken in
    fact” (internal quotation marks and citations omitted)).

    for a public use without having been appropriated under
    30
    eminent domain laws.” If the state “court finds that a
    taking has occurred, then the matter proceeds to the second
    stage where the court appoints appraisers and damages are
    assessed.” Jenkins v. Bd. of County Comm’rs of Madison
    County, 
    698 N.E.2d 1268
    , 1270 (Ind. Ct. App. 1998).
    In determining the first step, the Supreme Court of
    Indiana and Indiana appellate courts have recognized
    that there are “two discrete categories of regulations
    that violate the Takings Clause regardless of the legit-
    imate state interest advanced.” The first category en-
    compasses regulations that require the property owner
    to suffer a physical “invasion” of his or her property.
    The second category encompasses regulations that deny
    all economically beneficial or productive use of land.
    30
    The defendants appear to argue in their brief that the plaintiffs
    do not have any property rights in the Fawn River or its banks
    except a right to unimpeded river access and constructions of
    wharves, etc. See Appellees’ Br. at 19. As noted by the plaintiffs,
    the district court ruled when denying a prior motion to dismiss
    that the plaintiffs had a property interest in the riverbed and use
    of the river under state law. The district court held that for state-
    law purposes, the Fawn River was non-navigable, and thus under
    Indiana law, the plaintiffs had the right to “ ‘free and unmolested
    use and control of [their] portion of the [river] bed and water
    thereon for boating and fishing.’ ” R.51 at 19 (quoting Carnahan v.
    Moriah Property Owners Ass’n Inc., 
    716 N.E.2d 437
    , 441 (Ind.
    1999)).
    Because we determine that plaintiffs were required to exhaust
    their remedies in state court, we do not have jurisdiction to
    determine whether or not a taking took place and thus we will
    not delve into the issue of what property rights were or were not
    held by the plaintiffs under Indiana state law.

    (noting that a “taking is recognized not only for physical
    seizure or invasion of property by the government,” but also
    when a property owner is deprived of the “economically
    viable use of his property” (emphasis added)). This recogni-
    tion of two categories of takings for purposes of inverse
    condemnation proceedings, see 
    Georgetown, 786 N.E.2d at 1139
    , comports with the takings doctrine espoused by the
    31
    Supreme Court of the United States.
    Furthermore, Indiana law also mirrors federal constitu-
    tional law in that a physical invasion need not deprive an
    owner of all economically beneficial use of the land in order
    to be compensable; rather, the Supreme Court of Indiana
    has stated that a taking occurs whenever the state
    “compel[s] a property owner to suffer a physical invasion,
    31
    In Palazzolo v. Rhode Island, 
    533 U.S. 606
    (2001), the Supreme
    Court recognized that “even a minimal permanent physical
    occupation of real property requires compensation under the
    Clause” and that “with certain qualifications . . . a regulation
    which denies all economically beneficial or productive use of
    land will require compensation under the Takings Clause.” 
    Id. at 617
    (internal quotation marks and citations omitted). The
    Supreme Court of Indiana has noted generally that the property
    takings protections provided by the Indiana Constitution are
    coextensive with those provided by the Federal Constitution. See
    Cheatham v. Pohle, 
    789 N.E.2d 467
    , 472-73 (Ind. 2003).
    48                                                   No. 02-1863
    no matter how minute, of his property.” 
    Leisz, 702 N.E.2d at 1028-29
    (emphasis added); see 
    Loretto, 458 U.S. at 427
    . Thus,
    Indiana recognizes a physical invasion taking claim, even
    for a minute physical invasion of a plaintiff’s property.
    In light of the distinction that Indiana law recognizes
    between takings characterized by a physical invasion and
    those that are not, we do not believe that the plaintiffs’ ar-
    guments based on Mendenhall and Galbraith are compelling.
    As noted above, plaintiffs cite those cases for the proposi-
    tion that a plaintiff may not pursue a state inverse condem-
    nation action absent a showing that he has been deprived of
    all economically beneficial use of his property; however,
    neither case concerned a valid claim of a physical invasion
    32
    taking. As just reviewed, recent Indiana cases, including
    32
    In Mendenhall v. City of Indianapolis, 
    717 N.E.2d 1218
    (Ind. Ct.
    App. 1999), the state twice had seized the plaintiff’s property and
    later had allowed him use of it if he signed a covenant that the
    property would not be used for “any adult use in the future.” 
    Id. at 1228.
    However, the court did not consider whether the physical
    seizures constituted takings because the plaintiff had failed to
    challenge the seizures in a timely manner in state court. 
    Id. (“Mendenhall passed
    up his opportunity to argue the validity of
    the order and the subsequent seizure of his property.”). The
    plaintiff also had argued that the restrictive covenant was a
    taking; with respect to this argument, the court stated that
    “Mendenhall has not shown that the covenant deprived his
    property of ‘all economically beneficial or productive use.’
    Mendenhall has failed to show that a ‘taking’ of his property for
    public use without compensation to him has occurred.” 
    Id. (quoting Galbraith
    v. Planning Dep’t of Anderson, 
    627 N.E.2d 850
    ,
    854 (Ind. Ct. App. 1994)).
    At issue in Galbraith v. Planning Department of the City of
    Anderson, 
    627 N.E.2d 850
    (Ind. Ct. App. 1994), was a zoning

    No. 02-1863                                                        49
    inverse condemnation cases such as 
    Georgetown, 786 N.E.2d at 1139
    , state that there are two categories of takings: phy-
    sical invasion takings and takings that deprive the owners
    of all economically beneficial use of their property. There is
    no indication in Indiana law that owners who suffer a
    physical invasion also must lose all economically beneficial
    use of their property in order to bring an inverse condemna-
    tion action. Consequently, we believe that the statements in
    Mendenhall and Galbraith, when placed in the correct factual
    and legal context, do not apply to physical-invasion takings.
    Therefore, in contrast to the situation in Daniels, we have
    failed to find any cases indicating that Indiana would not
    recognize a state action for a physical-invasion taking.
    Indeed, all indications are that plaintiffs have a state rem-
    edy—a state inverse condemnation action—which they have
    not pursued. We must conclude, therefore, that the plaintiffs
    have not exhausted their state remedies as required by
    Williamson County, and their takings claim is not properly
    before this court.

    ordinance that restricted the plaintiff’s use of his property. In
    determining whether the zoning ordinance constituted a taking,
    the court stated that “a zoning regulation ‘goes too far,’ that is, is
    confiscatory, when it denies the property owner ‘all economically
    beneficial or productive use of the land.’ ” 
    Id. at 853
    (quoting
    Lucas v. South Carolina Coastal Council, 
    505 U.S. 1003
    , 1015 (1992)).
    Thus, the statements that an owner must show that all eco-
    nomically beneficial use of property has been lost before insti-
    tuting a state inverse condemnation action arose in the context of
    regulations on the use of property, not in the context of a physical
    invasion of property.

    D. Procedural Due Process
    The plaintiffs argue that the DNR deprived them of
    their property without due process of law when it caused
    the dredged material from the supply pond to invade and
    destroy their property. Although not discussed by the
    parties, our case law explains that the Williamson County
    exhaustion requirement applies with full force to due pro-
    cess claims (both procedural and substantive) when based
    on the same facts as a takings claim. See Hager v. City of
    West Peoria, 
    84 F.3d 865
    , 869 (7th Cir. 1996) (stating that
    “[t]he exhaustion requirement of Williamson County ap-
    plies whether plaintiffs claim an uncompensated taking,
    inverse condemnation, or due process violation” and thus
    the plaintiffs were required to “first pursue their claims,
    whether in the form of a takings challenge or a due process
    33
    claim, in . . . state court”). We have explained that, al--
    though we recognize that a governmental taking of property
    may encompass due process concerns, nevertheless, “due
    process challenges are premature if the plaintiff has not
    exhausted possible state remedies by which to attack the
    zoning regulation or other state action” creating the taking.
    Covington Ct. Ltd. v. Vill. of Oak Brook, 
    77 F.3d 177
    , 179 (7th
    Cir. 1996). Thus, the plaintiffs’ procedural due process claim
    33
    See also River Park, Inc. v. City of Highland Park, 
    23 F.3d 164
    , 167
    (7th Cir. 1994) (noting that “[l]abels do not matter” and holding
    that a plaintiff could not avoid Williamson County’s exhaustion
    requirement simply by adopting the label of “procedural due
    process”); 
    Forseth, 199 F.3d at 370
    (explaining that a “substantive
    due process claim [that] falls within the framework for takings
    claims” is “subject to Williamson’s requirement that [the plaintiffs]
    seek a final decision and pursue state court remedies before
    federal courts have jurisdiction to hear their case”).
    No. 02-1863                                                      51
    based on a deprivation of a property interest also is barred
    34
    from federal review.
    Conclusion
    For the foregoing reasons, the judgment of the district
    court with respect to the CWA claim is reversed, and that
    claim is remanded for further proceedings consistent with
    this opinion. The judgment of the district court with respect
    to the plaintiffs’ takings and procedural due process claims
    is affirmed. The plaintiffs may recover their costs in this
    court.

    Additionally, because we find that plaintiffs have failed to
    exhaust their administrative remedies, we need not and do not
    address the issue of whether the draw-down of the pond was a
    random, unauthorized act or whether the DNR employees
    possessed the requisite intent to establish a due process violation.
