    Appeals from the United States District Court
    for the Middle District of Florida
    _________________________
    (June 28, 2011)
    Before MARCUS and ANDERSON, Circuit Judges, and MILLS,* District Judge.
    PER CURIAM:
    The Georgia Parties,1 Gwinnett County, Georgia, and the United States Army
    Corps of Engineers (“the Corps”) appeal from the Middle District of Florida’s grant
    of summary judgment in this consolidated suit. The appeal arises from more than
    20 years of litigation involving the above parties as well as the States of Alabama
    and Florida, Alabama Power Company, the City of Apalachicola, Florida, and
    Southeastern Federal Power Customers, Inc. (“SeFPC”), a consortium of
    companies that purchase power from the federal government. All of the underlying
    cases2 relate to the Corps’ authority to operate the Buford Dam and Lake Lanier,
    *
    Honorable Richard Mills, United States District Judge for the Central District of Illinois,
    sitting by designation.
    1
    The designation “Georgia Parties” refers to the State of Georgia, the City of
    Atlanta, Fulton County, DeKalb County, the Cobb County-Marietta Water Authority, the City of
    Gainesville, the Atlanta Regional Commission, and the Lake Lanier Association. Gwinnett
    County, Georgia appeals separately and is not included in this denomination.
    2
    The four underlying cases are Alabama v. United States Army Corps of
    Engineers; Southeastern Federal Power Customers, Inc. v. Caldera; Georgia v. United States
    Army Corps of Engineers; and City of Apalachicola v. United States Army Corps of Engineers.
    3
    the reservoir it created, for local water supply. In its order, the district court found
    that the Corps’ current operation of the Buford Project—Buford Dam and Lake
    Lanier collectively—had allocated more than 21% of Lake Lanier’s storage space
    to water supply. The court determined that such an allocation exceeded the Corps’
    statutory authority and ordered the Corps to drastically reduce the quantity of water
    that it made available for water supply. The court’s summary judgment order also
    affirmed the Corps’ rejection of Georgia’s 2000 request for additional water supply
    allocations to meet the needs of the localities through 2030. The court stayed its
    order for three years to give the parties time to reach a settlement or to approach
    Congress for additional water supply authority.
    On appeal, the parties argue several jurisdictional matters. Alabama and
    Florida3 contend that this Court does not have appellate jurisdiction to hear the
    appeal of three of the four underlying cases because there is no final judgment in
    Subsequent short-form references to the district court and previous appellate decisions in the
    several cases will be as follows: Alabama v. United States Army Corps of Engineers as Alabama
    and Georgia v. United States Army Corps of Engineers as Georgia. Southeastern Federal Power
    Customers, Inc. v. Caldera became Southeastern Federal Power Customers v. Geren on appeal
    due to Luis Caldera’s succession by Pete Geren as Secretary of the Army. Short-form references
    to the district court case will be to SeFPC, while the appellate decision in the case will be
    referred to in the short-form as Geren.
    3
    The State of Alabama, the State of Florida, Alabama Power Company, and the
    City of Apalachicola have written a joint brief in this case. The designation “Alabama and
    Florida” refers to all four parties. The designation “Appellees” in this opinion refers to these four
    parties and SeFPC. The Corps is also an appellee in Georgia, but for the sake of clarity it will
    always be referred to by name.
    4
    the cases and pendent jurisdiction is inappropriate. The Georgia Parties and the
    Corps argue that the district court lacked jurisdiction over these three matters
    because there was no final agency action, and, therefore, the Administrative
    Procedures Act (“APA”) did not provide for judicial intervention at this juncture.
    The parties also assert a number of substantive claims. The Georgia Parties
    argue that the district court erred by concluding that the Corps lacked authority to
    allocate substantial quantities of storage in Lake Lanier to water supply on the
    basis of the legislation that authorized the creation of the Buford Project, the 1946
    Rivers and Harbors Act (“RHA”), Pub. L. No. 79-525, 60 Stat. 634 (1946).
    Although not in agreement with the Georgia Parties that water supply for the
    Atlanta area is an authorized project purpose under the RHA, the Corps does argue
    that the district court underestimated its authority to accommodate the water supply
    needs of the Atlanta area. The Georgia Parties and the Corps both assert that the
    district court erred by misinterpreting the scope of the Corps’ authority under the
    1958 Water Supply Act. The Georgia Parties and the Corps urge this Court to
    remand the case to the agency to make, in the first instance, a final determination of
    its water supply authority. Gwinnett County also individually asserts statutory,
    constitutional, and contractual claims relating to authority granted to it for its
    current withdrawals from Lake Lanier.
    5
    For the reasons explained below, we hold: First, the district court erred in
    finding that it had jurisdiction to hear Alabama, SeFPC, and Apalachicola because
    the Corps has not taken final agency action. The three cases therefore must be
    remanded to the Corps in order to take a final agency action. Second, the district
    court and the Corps erred in concluding that water supply was not an authorized
    purpose of the Buford Project under the RHA. The Corps’ denial of Georgia’s 2000
    water-supply request is therefore not entitled to Chevron deference, and the request
    must be remanded to the Corps for reconsideration. Third, the district court erred in
    finding that the 1956 Act, which authorized the Corps to contract with Gwinnett
    County to withdraw 10 million gallons of water per day, expired after 50 years.
    Gwinnett County’s contractual and just-compensation claims are without merit.
    Fourth, we also provide certain instructions to the Corps on remand. And finally,
    the Corps shall have one year to make a final determination of its authority to
    operate the Buford Project under the RHA and WSA. Our opinion is organized as
    follows:

    CONCLUSION
    FACTS AND PROCEDURAL HISTORY
    The facts of this appeal are intertwined with the history of Buford Dam and
    Lake Lanier. Buford Dam sits on the Chattahoochee River, approximately forty miles
    upstream of Atlanta. The Chattahoochee’s headwaters are in Northeastern Georgia in
    7
    the Blue Ridge Mountains. The river flows southwest to Columbus and then along
    much of the length of the Georgia-Alabama border and into the Florida Panhandle,
    where it combines with the Flint River to form the Apalachicola River. The
    Chattahoochee, Flint, and Apalachicola Rivers together are referred to as the ACF
    Basin.
    The Corps first began surveying the ACF Basin for suitable sites for
    hydroelectric facilities at the request of Congress in 1925. River and Harbor Act of
    1925, Pub. L. No. 68-585, ch. 467, 43 Stat. 1186, 1194 (Mar. 3, 1925). As a result of
    this survey, the Corps produced a report in 1939. See H.R. Doc. No. 76-342 (1939)
    [hereinafter “Park Report”]. The Park Report analyzed eleven projects at various
    stages of development in the ACF basin, including one at Roswell, Georgia, sixteen
    miles north of Atlanta. 
    Id. ¶ 196.
    District Engineer Colonel R. Park, the report’s
    author, referred to transportation, hydroelectric power, national defense, commercial
    value of riparian lands, recreation, and industrial and municipal water supply as
    “principal direct benefits” of the various projects under consideration. Park Report ¶
    243. Col. Park noted that at the time the Atlanta area had no immediate need for
    increased water supply, though such a future need was “not improbable.” Park Report
    ¶ 260. He stated that a large reservoir might have value as “an assured continuous
    water supply” due to the “continued rapid growth of the area.” 
    Id. Though he
    assigned
    8
    the other direct benefits a monetary value, he declined to do so for water supply,
    presumably because the benefit of this purpose, unlike all of the others, could only
    accrue in the future, rendering any valuation at that time speculative. Congress
    adopted the Corps’ proposals in the Park Report in full in its 1945 RHA. Pub. L. No.
    79-14, 59 Stat. 10, 17 (1945).
    In 1946, the Corps, in its “Newman Report,” recommended certain amendments
    and revisions to the original plan for the ACF system, including combining several of
    the hydroelectric sites near Atlanta into one large reservoir at Buford, Georgia to
    increase power generation and to better regulate flows downstream. H.R. Doc. No. 80-
    300, ¶ 69 (1947) [hereinafter “Newman Report”]. Division Engineer Brigadier General
    James B. Newman noted that the Chattahoochee River would be an excellent source
    of hydropower. Newman Report ¶ 7. According to Newman, a large reservoir—what
    would become Lake Lanier—was needed to make the locks and dams downstream
    more effective. The Newman Report noted that the proposed dam at Buford would be
    valuable for the purpose of flood control because of the frequent flooding in the basin
    and the severe damage that previous floods had caused. The report also explained that
    the various dams in the proposal would help keep flows continuous. These continuous
    flows would benefit navigation because they would allow barges to travel from
    Atlanta to Columbus and beyond, and they would assure a source of water supply for
    9
    the City of Atlanta. Just as the Park Report had done before it, the Newman Report
    attempted to quantify the value of the benefits of the project. Only three value-
    calculated benefits were listed: power, navigation, and flood control. 
    Id. ¶ 98,
    Table
    10. It is probable that Newman, like Park, deemed there to be no immediate benefit
    from water supply, rendering any benefit purely prospective and any valuation of this
    benefit entirely speculative.
    The Newman Report, at several junctures, spoke of the benefit that the dam
    would provide for water supply. The report concluded that the project would “greatly
    increase the minimum flow in the river at Atlanta,” which would safeguard the city’s
    water supply during dry periods. 
    Id. ¶ 68.
    In discussing the operation of the dam, the
    Newman Report noted that releases of 600 cubic feet per second (“cfs”) should be
    made during off-peak hours4 in order to ensure a continuous flow of the river at
    Atlanta of not less than 650 cfs, even though this flow would have a slight detrimental
    effect on power generation. The report noted that this “minimum release may have to
    be increased somewhat as the area develops.” 
    Id. ¶ 80.
    The Report expected that any
    decrease in power value would be marginal and outweighed by the benefits of an
    4
    Off-peak hours are those time periods when the demand for power is relatively
    low. Hydroelectric plants attempt to minimize the amount of water released during off-peak
    hours so that power generation can operate at maximum levels during peak hours when the
    demand for power is high.
    10
    “assured” water supply for the City of Atlanta. 
    Id. The 1946
    RHA stated that the
    project would be “prosecuted . . . in accordance with the report of the Chief of
    Engineers, dated May 13, 1946,” Pub. L. No. 79-525, 60 Stat. 634, 635 (1946).
    Because that report incorporated the Newman Report in full, the Newman Report
    became part of the authorizing legislation for the project.
    Congress continued to consider the purposes of the Buford Dam in debates
    about appropriations bills for the project’s funding. The purposes mentioned most
    frequently in Congressional hearings were power, navigation, and flood control, but
    water supply was also discussed with some frequency. Then-mayor of Atlanta,
    William Hartsfield testified before a Senate subcommittee that water from the
    Chattahoochee was “necessary” but that Atlanta did not immediately need the water
    in the same manner as cities in more arid locations. Civil Functions, Dep’t of the Army
    Appropriation Bill 1949: Hearing Before the Subcomm. of the S. Comm. on
    Appropriations, 80th Cong. 644 (statement of William B. Hartsfield, Mayor, Atlanta,
    Georgia). Congress debated whether Atlanta should be asked to contribute part of the
    cost of building the Buford Dam. Corps officer Colonel Potter testified that the Corps
    was not recommending that Atlanta be asked to pay because the services that would
    be provided in the field of water supply were all incidental to the purposes of
    hydropower and flood control and would “not cost the Federal Government 1 cent to
    11
    supply.” Civil Functions, Dep’t of the Army Appropriations for 1952: Hearings Before
    the Subcomm. of the H. Comm. on Appropriations, 82d Cong. 121–122 (1951)
    (exchange between Rep. Gerald Ford, Member, H. Comm. on Appropriations, and Col.
    Potter, Corps officer). Congressman Gerald Ford presciently asked Colonel Potter
    whether it was foreseeable that one day in the future Atlanta would begin to request
    greater amounts of water from the project. 
    Id. at 122.
    Col. Potter responded that the
    Corps would have to study the effect that such a request would have on power
    production. He said that the Corps would have to obtain additional water supply
    authorization if a request amounted to “a major diversion of water.” 
    Id. Ultimately, Atlanta
    was never asked to, and did not, contribute to the construction costs.
    The Corps released its “Definite Project Report” for the project in 1949. The
    report provided a detailed discussion of the plans for the Buford Project and its
    operations. The report referred to flood control, hydroelectric power, navigation, and
    an increased water supply for Atlanta as “the primary purposes of the Buford project.”
    U.S. Army Corps of Eng’rs: Mobile District, Definite Project Report on Buford Dam
    Chattahoochee River, Georgia, ¶ 48 (1949) [hereinafter “Definite Project Report”]. A
    later passage in the report referred to flood control, power generation, navigation, and
    water supply as “principle purposes of the Buford project.” 
    Id. ¶ 115.
    The report
    concluded by calculating and explaining the benefits of the various project purposes.
    12
    As to water supply, it explained that the project would result in “[a] real benefit,” but
    it did not estimate the monetary value because “definite evaluation of this benefit
    cannot be made at this time.” 
    Id. ¶ 124.
    Buford Dam was constructed from 1950 to 1957, creating the reservoir known
    today as Lake Sidney Lanier. The Southeastern Power Administration (“SEPA”), the
    federal government agency from which SeFPC purchases the power generated at the
    dam, paid approximately $30 million of the $47 million of construction costs. The
    creation of Lake Lanier inundated the water intake structures of the Cities of Buford,
    Georgia and Gainesville, Georgia. As a method of compensation, the Corps signed
    relocation agreements with the two municipalities authorizing water withdrawals
    directly from the reservoir—these agreements allowed Gainesville to withdraw 8
    million gallons per day (“mgd”)5 and Buford 2 mgd.6 Although no storage7 was
    specifically allocated for water supply, the fact that the dam operated during “off-
    peak” hours, to the detriment of power generation, demonstrated that downstream

    United States of America and City of Gainesville, Georgia for Withdrawal from Lake Sidney
    Lanier.

    A contract to this effect was entered into on December 19, 1955. Contract

    7
    Storage refers to the amount of space in Lake Lanier dedicated to a particular
    project purpose. Lake Lanier is the reservoir for the Buford Project and provides space sufficient
    to store approximately 2.5 million gallons of water.
    13
    water supply was a consideration. In accordance with the recommendations of the
    Newman Report, the Corps maintained the necessary minimum river flow at Atlanta
    by making off-peak releases of 600 cfs during these hours of the week.
    During construction of the dam, Gwinnett County requested permission from
    the Corps to withdraw 10 mgd directly from Lake Lanier. The Corps denied the
    request, explaining that the approval of Congress was required for it to meet such a
    request. In 1955, the Corps stated to Congress that the proposed withdrawals would
    be in the public interest and would not have a materially adverse effect on downstream
    interests or power output. F.G. Turner, Ass't Chief, Eng'g Div., U.S. Army Corps of
    Eng’rs: Mobile District, Report on Withdrawal of Domestic Water Supply from
    Buford Reservoir ¶ 1 (1955). The following year, Congress passed a law that granted
    the Corps authority to enter into a contract with Gwinnett County for the allocation of
    11,200 acre-feet of storage for regulated water supply and granted the county an
    easement across government property for the construction and maintenance of a
    pumping station and pipelines. Pub. L. No. 84-841, 70 Stat. 725 (1956).
    Construction was completed in 1957. Lake Lanier covers 38,000 acres and has
    692 miles of shoreline. The large size of the lake allows for a substantial benefit in the
    form of recreation.
    Lake Lanier is divided into three tiers, or pools, divided by elevation. The first
    14
    tier extends from the bottom of the lake, at an elevation of 919 feet above sea level,
    to an elevation of 1,035 feet. This tier holds 867,600 acre-feet of “inactive” storage.
    The inactive pool is generally left untouched and saved for instances of severe
    drought. The next tier extends from an elevation of 1,035 feet to an elevation of 1,070
    feet (1,071 feet in the summer) and contains 1,049,000 acre-feet (1,087,600 acre-feet
    in the summer) of conservation storage. The conservation pool generally provides the
    water that is used for all downstream purposes. The Newman Report contemplated that
    conservation storage would be used primarily for hydropower and repeatedly referred
    to it as storage for power. The final tier extends from an elevation of 1,070 feet (1,071
    feet in the summer) to an elevation of 1085 feet. This tier provides 598,800 acre-feet
    of flood storage. The flood pool is generally left empty so that it can accommodate
    excess water during flood conditions.
    Buford Dam was constructed to release water from Lake Lanier through a
    powerhouse that generates hydropower. The powerhouse contains three turbines. Two
    of the turbines are large and release about 5,000 cfs when running. These two turbines
    operate during peak hours, when energy consumption is at its greatest. They are the
    most efficient source of power generation—generating 40,000 kilowatt hours (“kwh”)
    originally and 60,000 kwh after improvements in 2004—and would be the only
    turbines used if a minimum off-peak flow at Atlanta were not a project concern. To
    15
    accommodate this concern, the powerhouse also contains a third, smaller turbine
    which releases 600 cfs, generating approximately 7,000 kwh. At peak performance,
    the dam releases approximately 11,000 cfs of water into the river. However, when
    energy demand is low—so-called off-peak hours—only the small turbine is operated,
    allowing the dam to produce some energy while providing for a minimal continuous
    flow. The Corps can also release water through a small sluice gate, but this is typically
    done only when the small turbine is shut down for repairs or in cases of an emergency.
    In this manner, Buford Dam was designed to generate maximum power while also
    ensuring a minimum continuous flow of water downstream to accommodate water
    supply.
    In 1958, Congress passed the Water Supply Act (“WSA”). The statute was
    designed to allocate some storage in multi-purpose projects like Buford to water
    supply. The policy underlying the statute was:
    to recognize the primary responsibilities of the States and local interests
    in developing water supplies for domestic, municipal, industrial, and
    other purposes and that the Federal Government should participate and
    cooperate with States and local interests in developing such water
    supplies in connection with the construction, maintenance, and operation
    of Federal navigation, flood control, irrigation, or multiple purpose
    projects.
    43 U.S.C. § 390b(a) (2011). To further that policy, Congress authorized the Corps to
    allocate storage in federal reservoirs for water supply, provided that the localities paid
    16
    for the allocated storage. 
    Id. § 390b(b).
    However, Congress placed the following
    limitation on its authorization:
    Modifications of a reservoir project heretofore authorized, surveyed,
    planned, or constructed to include storage as provided by subsection (b)
    of this section which would seriously affect the purposes for which the
    project was authorized, surveyed, planned, or constructed, or which would
    involve major structural or operational changes shall be made only upon
    the approval of Congress as now provided by law.
    
    Id. § 390b(d)
    (emphasis added). The policy of subsection (a) indicates that Congress
    aimed only to expand water supply allocations, not contract them by limiting previous
    authorizations. The articulation of the bounds of the statute’s authorization makes no
    mention of a limit on previously granted water supply authorization. In the case of
    Buford, the WSA’s grant of authority for water supply constitutes a supplement to any
    authority granted by the 1946 RHA.
    In 1959, the Corps issued its Reservoir Regulation Manual for Buford Dam
    (“Buford Manual”) as an appendix to the Corps’ 1958 manual for the entire river basin.
    U.S. Army Corps of Eng’rs: Mobile District, Apalachicola River Basin Reservoir
    Regulation Manual, Appendix B (1959). The Buford Manual has not been updated and
    remains in effect today. The manual describes the technical features of the dam,
    including a description of the three tiers and their storage capacities, the size of Lake
    Lanier, and the general operation of the plant. It states that the project will be run to
    17
    maximize releases of water during peak hours but will also utilize off-peak releases in
    order to maintain a minimum flow of 650 cfs at Atlanta.8 
    Id. at B-13.
    The manual
    makes multiple mentions of regulations that are designed to ensure this minimum flow.
    
    Id. at B-18–19,
    B-22.
    There was very little change in water supply operations at the Buford Project
    between 1960 and 1973. Only Gainesville and Buford withdrew water directly from
    Lake Lanier. Gwinnett, with which the Corps was authorized to contract, did not
    withdraw water directly from the reservoir. In the meantime, the City of Atlanta and
    DeKalb County withdrew water from the river downstream from the dam but made no
    recorded requests that the schedule of releases be altered to accommodate their needs.
    The Atlanta metropolitan area increased its water use from the Chattahoochee by 37%
    (from 117 mgd to 160 mgd) between 1960 and 1968. U.S. Army Corps of Eng’rs:
    Mobile District, Final Environmental Impact Statement: Buford Dam and Lake Sidney
    Lanier, Georgia (Flood Control, Navigation and Power), Statement of Findings 14
    (1974). This amount was still well below the amount released by the Corps to maintain
    a minimum off-peak flow. Moreover, between 1956 and 1969, the number of
    residences within two and a quarter miles of the reservoir doubled. 
    Id. at 15.
    The
    8

    growing water needs of Atlanta came to the attention of the Senate, which in 1973
    commissioned the Metropolitan Atlanta Area Water Resources Management Study
    (“MAAWRMS”) to develop a plan for the long-term needs of the Atlanta area. The
    study was conducted by the Corps, the Atlanta Regional Commission (“ARC”), the
    State of Georgia, and the U.S. Environmental Protection Agency in combination.
    By the 1970s, it became clear that area localities desired greater access to water
    in Lake Lanier. The Corps determined that it could not grant permanent water
    allocation rights to the localities before the completion of the MAAWRMS. While the
    study was being performed, the Corps entered into a number of interim contracts for
    water withdrawal. The first water supply contract was given to Gwinnett County and
    allowed for the withdrawal of up to 40 mgd directly from Lake Lanier during the
    course of the study. Contract of July 2, 1973, Gwinnett Record Excerpts vol. 1,
    ACF004024. The contract cited the WSA for authority and was based on findings of
    the Corps’ District Engineer that the proposed withdrawals would not have significant
    adverse affects on the other authorized purposes of the project. No mention was made
    of the 1956 Act, possibly because the Act authorized only 10 mgd and thus would not
    have been sufficient authority for the Corps’ actions. In 1975, the county informed its
    bond investors that the construction costs alone for its water supply facilities would be
    $28 million.
    19
    In 1975, the Corps concluded, and SEPA agreed, that the Buford Project could
    supply an annual average of 230 mgd of water for downstream withdrawal (with a
    maximum of 327 mgd in the summer) without significantly affecting hydropower
    generation. The Corps revised this number in 1979, concluding that by scheduling
    additional peak weekend releases it could raise the annual average to 266 mgd as an
    incident of power generation. In 1986, the Corps would again raise the figure for
    available water supply downstream incident to power generation, concluding that it
    could guarantee an annual average of 327 mgd by implementing a new water
    management system that had been proposed in the MAAWRMS.
    The final report of the MAAWRMS was issued in September 1981. The report
    evaluated three alternative plans for dealing with Atlanta’s increasing long-term water
    supply needs. The first alternative was to build a reregulation dam 6.3 miles below the
    Buford Dam. This new dam would store outflows released from Buford during peak
    operations and release them as needed for water supply. The study found that this
    alternative had the highest estimated ratio of benefits to costs. This alternative received
    the most support from federal and state agencies, and the study concluded it was best.
    The second alternative was to reallocate storage space in Lake Lanier for water supply.
    According to the study, in 1980, 10,512 acre-feet had been allocated to water supply,
    amounting to 14.6 mgd withdrawn directly from Lake Lanier. This alternative called
    20
    for an increase of allocated storage space to 141,685 acre-feet by the year 2010,
    allowing for a total withdrawal of 53 mgd from the lake. The final alternative was to
    dredge the Morgan Falls Reservoir, which lies downstream from Buford, and also
    reallocate 48,550 acre-feet of storage space in Lake Lanier for water supply by 2010.
    In 1986, Congress, in the Water Resources Development Act, authorized the
    construction of a reregulation dam, the MAAWRMS’ favored first alternative. Pub. L.
    No. 99-662, § 601(a)(1), 100 Stat. 4137, 4140–41. However, the project had previously
    not received approval from the Office of Management and Budget, which said that state
    and local money should be used to construct such a project, and Congress did not
    appropriate any funding towards the construction of the proposed reregulation dam.
    Shortly thereafter, the Corps determined that the second alternative of the
    MAAWRMS—reallocating storage in Lake Lanier instead of constructing a new
    dam—would be more economical. The change was based, at least in part, on an
    environmental study generated by new computer models that concluded that the costs
    of acquiring the land flooded by the reregulation dam could rise and make the first
    alternative less economical than originally thought. U.S. Army Corps of Eng’rs: Mobile
    District, Additional Information, Lake Lanier Reregulation Dam 2 (1988).
    In the late 1980s, the Corps began to prepare a Post-Authorization Change
    Notification Report (“PAC Report”) suggesting that the authorization for the new
    21
    reregulation dam be set aside in favor of the reallocation of storage alternative. A draft
    of the PAC Report was completed in 1989. The draft recommended that 207,000 acre-
    feet be allocated to water supply, allowing for 151 mgd to be withdrawn directly from
    Lake Lanier and 378 mgd (51 mgd more than the 327 mgd that the Corps determined
    was available as an incident of power supply) from the river downstream. This
    represented a significant increase from the 142,000 acre-feet of storage recommended
    by the second alternative of the MAAWRMS. The draft PAC Report also included a
    draft Water Control Manual that would have replaced the manual from 1958 and
    governed the Corps’ water operations in the ACF basin. In this appeal, the Corps
    claims that the PAC Report’s recommendations would have been made pursuant to
    authority from the WSA. The draft report itself noted the Corps’ authority under the
    statute but stated that approval from Congress might be required due to the fact that the
    allocation exceeded 50,000 acre-feet.9 The draft report estimated that the purchased
    9
    Internal policies require the Corps to obtain the approval of the Secretary of the
    Army for all storage allocations exceeding 15% of total storage capacity or 50,000 acre-feet,
    whichever is less. The parties have not made this Court aware of any internal regulations that set
    a threshold for allocations above which Congressional approval is required. However, the Corps
    had warned the preceding year that such a reallocation of storage might require Congressional
    approval:
    The Chief of Engineers has the discretionary authority to approve reallocation of
    storage if the amount does not exceed 50,000 acre-feet, or 15 percent of total
    usable storage, whichever is lower, and if the reallocation would not have a
    significant impact on authorized project purposes. [The reallocation contemplated
    in the MAAWRMS] would require the reallocation of 202,000 acre-feet of storage
    to meet the year 2010 peak demand of 103 mgd from the lake and 510 mgd from
    22
    storage in Lake Lanier would cost $49,360,600. The final PAC Report was never
    completed due to resistance and the initiation of a lawsuit by the State of Alabama.
    The Corps followed the recommendation of the MAAWRMS to make water
    available for water supply in the interim before a long-term solution was reached, as
    it had done while the study was being completed, and it entered into a temporary water
    supply contract with the ARC. The contract was based on the Corps’ revised
    determination that it could provide, incidentally to power generation, 327 mgd as a
    year-round average with no impact on hydropower. The Corps agreed to provide
    releases sufficient to accommodate up to 50 mgd in withdrawals above this 327 mgd
    threshold, for which the ARC would pay. The contract was renewed in 1989 but
    expired in 1990. Since then, the ARC has continued to withdraw water from the
    Chattahoochee on roughly the same basis as that specified in the contract, though it has
    generally not needed to withdraw more than 327 mgd.
    The Corps signed several other water supply contracts in the 1970s and 1980s,
    all of which expired in 1990, but which roughly dictate the terms under which the
    the river. . . . Therefore, the required reallocation is not within the discretionary
    authority of the Chief of Engineers to approve. It can only be approved by the
    [Assistant Secretary of the Army for Civil Works] if impacts are determined to be
    insignificant. We believe the power losses are significant and expect that
    Congressional approval would be required for the reallocation.

    localities have continued to withdraw water from the Buford Project. In 1978, the
    Corps agreed to terms with the City of Cumming, Georgia for the paid withdrawal of
    2.5 mgd. In 1985, the amount was raised to 5 mgd, and in 1987 it was raised to 10 mgd.
    In 1987, the Corps signed a contract with the City of Gainesville, allowing the city to
    withdraw up to 20 mgd, up from the 8 mgd authorized in 1953 as just compensation.
    The contract required Gainesville to pay for the water that it withdrew in excess of 8
    mgd. In 1988, the 1973 contract with Gwinnett County was supplemented, expanding
    the cap on withdrawals from 40 mgd to 53 mgd. All of the contracts signed in the
    1980s specifically stated that they were interim contracts to satisfy water supply needs
    while the Corps was studying the issue and determining a permanent plan. As a
    component of their interim nature, the contracts explicitly stated that they did not create
    any permanent rights to storage space in Lake Lanier. The Corps originally cited the
    Independent Offices Appropriations Act of 1952, 31 U.S.C. § 9701, as authority for
    these contracts, but it later deemed the statute to be ineffective in authorizing such
    transactions. Later contracts cited the Water Supply Act for authority.
    On January 1, 1990, all of the interim contracts expired. The only remaining
    water supply allocations were the combined 10 mgd granted to Buford and Gainesville
    in the 1950s by the Corps as just compensation. However, the Corps continued to
    permit the localities to withdraw water from the Buford Project for water supply.
    24
    Appellees refer to these water withdrawals as pursuant to “holdover” contracts.
    In June, 1990, Alabama filed suit against the Corps in the Northern District of
    Alabama to challenge a section of the draft PAC Report and the continued withdrawal
    of water from the Buford Project by the Georgia Parties, which Appellees characterize
    as a de facto reallocation of storage. This suit is the first of the four currently on appeal.
    In September of 1990, Alabama and the Corps moved jointly for a stay of proceedings,
    which was granted, to negotiate a settlement agreement. Florida and Georgia later
    intervened as plaintiff and defendant, respectively. The stay order at issue in Alabama
    v. United States Army Corps of Engineers, 
    357 F. Supp. 2d 1313
    (N.D. Ala. 2005),
    required the Corps not to “execute any contracts or agreements which are the subject
    of the complaint in this action unless expressly agreed to, in writing, by [Alabama] and
    Florida.” 
    Id. at 1316.
    The stay provided that either side could terminate it at will. It did
    not discuss the continued water withdrawals of the Georgia Parties.
    In 1992, Alabama, Florida, Georgia, and the Corps entered into a Memorandum
    of Agreement (“MOA”) authorizing a comprehensive study of the water supply
    question and requiring the Corps to withdraw the draft PAC Report along with its
    accompanying Water Supply Reallocation Reports and Environmental Assessments.
    The MOA contained a “live and let live” provision that allowed the Georgia Parties to
    continue to withdraw water from the Buford Project at the level of their withdrawals
    25
    in 1990, with reasonable increases over time. The provision made clear that it did not
    grant any permanent rights to the water being consumed. The MOA was originally set
    to last for three years but was extended several times.
    In 1997, after the completion of a comprehensive study, the parties entered into
    the Apalachicola-Chattahoochee-Flint River Basin Compact (“ACF Compact”), which
    was ratified by Congress and the three states and replaced the MOA. Pub. L. No. 105-
    104, 111 Stat. 2219 (1997). The ACF Compact included a provision allowing
    continued withdrawals similar to the live and let live provision in the MOA. The
    Compact created an “ACF Basin Commission” composed of the governors of the three
    states and a non-voting representative of the federal government, to be appointed by
    the President. The commission was charged with establishing “an allocation formula
    for apportioning the surface waters of the ACF Basin among the states of Alabama,
    Florida, and Georgia.” 
    Id. art. VI(q)(12),
    111 Stat. at 2222. Under the Compact,
    existing water supply contracts would be honored, and water-supply providers could
    increase their withdrawals “to satisfy reasonable increases in the demand” for water.
    
    Id. art. VII(c),
    111 Stat. 2223–24. The Compact initially was scheduled to expire
    December 31, 1998, but it was extended several times; it ultimately expired on August
    31, 2003, when the Commission failed to agree on a water allocation formula. The stay
    of the Alabama case remained in effect through the duration of the Compact. In the
    26
    meantime, the Corps continued to allow the Georgia Parties to withdraw water from the
    Buford Project. Because there were no contracts in place, the Corps froze the rates that
    it charged for water and continued to proceed on the basis of the prices that were set
    in the interim contracts of the 1980s. This rate scheme angered hydropower customers
    who purchased power produced by the project directly or indirectly from SEPA.
    In December 2000, SeFPC filed suit under the APA against the Corps in the
    United States District Court for the District of Columbia, the second of the four suits
    currently on appeal. SeFPC alleged that the agency had wrongfully diverted water from
    hydropower generation to water supply, thereby causing SeFPC’s members to pay
    unfairly high rates for their power. SeFPC sought a judicial declaration of the Buford
    Project’s authorized purposes as well as compensation. In March 2001, the district
    court referred the parties to mediation, and Georgia was joined. In January 2003,
    SeFPC, the Corps, and the Georgia Parties agreed to a settlement in the case, which
    called for an allocation of 240,858 acre-feet (estimated to be 22% of conservation
    storage) to water supply for once-renewable 10-year interim contracts that could be
    converted into permanent storage if approved by Congress (or if a court deemed
    Congressional approval unnecessary). In exchange, the Georgia Parties agreed to pay
    higher rates for water, with the income being applied as a credit against the rates
    charged to SeFPC’s members. The D.C. district court then allowed Alabama and
    27
    Florida to intervene.
    In October 2003, the Alabama court enjoined the filing of the settlement
    agreement in the D.C. case, finding that the agreement violated the stay in its case
    because the approval of Alabama and Florida was not obtained. The district court in the
    District of Columbia approved the Agreement in February 2004, contingent upon the
    dissolution of the Alabama court’s injunction, rejecting Alabama and Florida’s
    argument that the Agreement exceeded the Corps’ authority conferred by Congress.
    SeFPC, 
    301 F. Supp. 2d 26
    , 35 (D.D.C. 2004). In April 2004, a panel of this Court
    stayed an appeal of the Alabama court’s injunction to allow the Alabama district court
    to decide whether to dissolve or modify the injunction in light of the D.C. district
    court’s order approving the Agreement. In the meantime, an initial appeal of the D.C.
    district court’s order in SeFPC by Alabama and Florida was denied by the D.C. Circuit
    Court of Appeals for lack of a final judgment. The Alabama district court denied a
    motion to dissolve the preliminary injunction, 
    Alabama, 357 F. Supp. 2d at 1320-21
    ,
    but in September 2005, a panel of this Court held that the district court abused its
    discretion in granting the injunction and vacated the injunction. Alabama, 
    424 F.3d 1117
    , 1133 (11th Cir. 2005). Once this Court dissolved the injunction over the
    implementation of the Agreement, the D.C. district court in March 2006 entered a final
    judgment in SeFPC, and Alabama and Florida again appealed to the D.C. Circuit.
    28
    In Southeastern Federal Power Customers, Inc. v. Geren, 
    514 F.3d 1316
    , 1324
    (D.C. Cir. 2008), the D.C. Circuit held that the settlement agreement exceeded the
    Corps’ authority under the WSA. The parties to the settlement agreement argued that
    the Corps was authorized to enter into the settlement on the basis of its WSA authority
    alone, so the court specifically refrained from making any holdings on the basis of the
    RHA. 
    Id. at 1324
    n.4. The court found that “[o]n it’s face, . . . reallocating more than
    twenty-two percent . . . of Lake Lanier’s storage capacity to local consumption uses . . .
    constitutes the type of major operational change referenced by the WSA.” 
    Id. at 1324
    .
    After the circuit court’s remand, the Judicial Panel on Multidistrict Litigation
    transferred the case, along with Alabama and several others, to the Middle District of
    Florida.
    Meanwhile, in 2000, the State of Georgia submitted a formal request to the Corps
    to modify its operation of the Buford Project in order to meet the Georgia Parties’ water
    supply needs through 2030. The request was to withdraw 408 mgd from the river and
    297 mgd directly from the lake, which, combined, required approximately 370,930
    acre-feet of storage. In February 2001, nine months after the request was sent to the
    Corps and without a response from the Corps, the State of Georgia filed suit in the
    United States District Court for the Northern District of Georgia seeking to compel the
    Corps to grant its request, beginning the third of the four underlying cases. The Corps
    29
    responded in April 2002 with a letter denying the request and an accompanying legal
    memorandum. Memorandum from Earl Stockdale, Deputy General Counsel,
    Department of the Army, to Acting Assistant Secretary of the Army for Civil Works:
    Georgia Request for Water Supply from Lake Lanier 1 (Apr. 15, 2002) [hereinafter
    “2002 Stockdale Memo”]. The 2002 Stockdale Memo concluded that the Corps lacked
    the authority to grant Georgia’s request without legislative approval. The memo stated
    that water supply was not an authorized purpose of the Buford Project under the RHA.
    Further, it stated that even if water supply was authorized, the Corps would still lack
    the authority to make a storage allocation of the size requested because the reallocation
    “would involve substantial effects on project purposes and major operational changes.”
    
    Id. The district
    court denied Florida’s and SeFPC’s motions to intervene in the case,
    but this Court reversed the denial and remanded for further proceedings. Georgia v.
    U.S. Army Corps of Eng’rs, 
    302 F.3d 1242
    , 1260 (11th Cir. 2002). On remand, Florida
    moved to dismiss or abate the proceedings; Alabama, Gwinnett County, the City of
    Gainesville, and the ARC moved to intervene; and Alabama moved to abate or transfer
    the proceedings. The district court allowed Alabama to intervene as of right and the
    local governments to intervene permissively, and it held that the case would be abated
    pending the resolution of the Alabama case. Georgia, 
    223 F.R.D. 691
    , 699 (N.D. Ga.
    2004). On appeal, a panel of this Court in an unpublished decision affirmed the district
    30
    court’s decision to abate the case. Georgia, 144 F. App’x 850 (11th Cir. 2005). The
    case was then consolidated into the multidistrict litigation in the Middle District of
    Florida.
    In January 2008, the City of Apalachicola sued the Corps in the federal district
    court for the Northern District of Florida. This is the last of the four cases being
    considered as part of this appeal. This case was also consolidated into the multidistrict
    litigation.
    While the litigation was pending, the Corps began an update of its plans and
    operations in the ACF Basin with a focus on whether it could continue to meet the
    current water supply needs of the localities. In order to answer these question,
    specifically in light of the D.C. Circuit’s Geren opinion, the Corps released a new legal
    memorandum by Earl Stockdale. Memorandum from Earl Stockdale, Chief Counsel,
    Department of the Army, to the Chief of Engineers: Authority to Reallocate Storage for
    Municipal & Industrial Water Supply Under the Water Supply Act of 1958, 43 U.S.C.
    § 390b 1 (Jan. 9, 2009) [hereinafter “2009 Stockdale Memo”]. In this memorandum, the
    Corps determined that the current water supply withdrawal under the “interim
    contracts” could be accommodated by a permanent reallocation of approximately
    11.7% of the conservation storage in Lake Lanier. The Corps concluded that such a
    permanent reallocation would not constitute a major operational change, and it would
    31
    not seriously affect any project purposes.
    The Middle District of Florida, in its consideration of the multidistrict litigation,
    divided the trial into two phases. Phase One, which is at issue here, pertained to the
    Corps’ authority for its operations of the project. The plaintiffs in the four underlying
    cases moved for summary judgment, and the Corps filed an opposition and cross-
    motion for summary judgement in each case. On July 17, 2009, the court granted partial
    summary judgment to the plaintiffs in Alabama, Apalachicola, and SeFPC and to the
    Corps in Georgia, and it denied summary judgment to the Georgia Parties.
    The court’s order concluded that the Corps had exceeded its authority in its “de
    facto” reallocation of storage to accommodate current water supply withdrawals. In re
    Tri-State Water Rights Litig., 
    639 F. Supp. 2d 1308
    , 1350 (M.D. Fla. 2009). The court
    first held that only two conclusions of the D.C. Circuit had preclusive effect on its
    judgment under the principle of collateral estoppel: (1) that the WSA applied to interim
    reallocations of storage; and (2) that a reallocation of 22% of Lake Lanier’s total
    conservation storage was a major operational change under the WSA. 
    Id. at 1343.
    Next,
    the district court concluded that there was virtually no authorization for the reallocation
    of water supply storage in the RHA and that the Corps’ sole source of authority to
    allocate storage for water supply was the WSA.
    The court went on to hold that the 2009 Stockdale Memo was a litigation
    32
    document with post hoc analysis that was not part of the administrative record. 
    Id. at 1347.
    Without the memo, the district court concluded that the record contained
    insufficient support for the Corps’ calculations of the amount of storage required for
    the water supply withdrawals as of 2006. The court attempted its own calculation of
    this figure and determined that the allocation was for 226,600 acre-feet or 21.5% of
    Lake Lanier’s total conservation storage. 
    Id. at 1350.
    In reaching its conclusion on the
    amount of storage necessary for the project’s current operations, the court rejected
    several key figures that the Corps had used in making previous calculations, most
    notably rejecting the Corps’ figure for the amount of water available for downstream
    withdrawal as a byproduct of hydropower operations. The district court held that the
    21.5% allocation was a major operational change that exceeded the Corps’ WSA
    authority. The court also concluded that the Corps’ current operations exceeded the
    WSA because they seriously affected the authorized purpose of hydropower generation.
    Because the Georgia request represented an even larger water supply storage allocation
    than the current operations, the court also found that it exceeded the Corps’ authority.
    The district court directed the Corps to limit releases from the Buford Project to
    600 cfs during off-peak hours and to discontinue all water supply withdrawals being
    made directly from Lake Lanier, except for the 10 mgd that Gainesville and Buford had
    33
    been permitted to withdraw in their 1950s reallocation agreements.10 The court stayed
    its order for three years, until July 17, 2012, to give the parties an opportunity to settle
    or to seek Congressional approval. In the meantime, the court allowed current
    withdrawals to continue but forbade any increases without the consent of all of the
    parties.
    DISCUSSION
    This opinion will begin by examining threshold jurisdictional questions, then
    will analyze the primary substantive matters involved, and finally will provide some
    guidance and instruction for the Corps pertaining to its analysis of its water supply
    authority on remand.
    Part I.         Jurisdictional Matters
    A.     Appellate Jurisdiction over Alabama, SeFPC, and Apalachicola
    Alabama and Florida argue that this court lacks appellate jurisdiction over the
    10
    The district court failed to state its reasoning for choosing 600 cfs as the level for
    off-peak releases. Six hundred cfs was the rate of off-peak releases in the 1950s when the plant
    opened. The Newman Report explicitly contemplated raising off-peak releases so as to provide
    for a minimum flow of the river at Atlanta of 800 cfs by 1965. Newman Report ¶ 79. The district
    court fails to explain why it mandated that the level of off-peak releases not be raised from where
    it stood at the time of the Buford Project’s construction in spite of the fact that the RHA
    explicitly contemplated such a raise and in spite of the additional water supply authority granted
    to the Corps by the WSA. As our discussion below will make apparent, the district court
    committed obvious error in this regard. See infra, note 19.
    34
    appeals in Alabama, SeFPC, and Apalachicola. They note that the district court did not
    render a final judgment in the cases, as the summary judgment order on the Phase One
    claims did not resolve the Phase Two claims in those cases. Appellees concede that this
    court has jurisdiction over the appeal in the Georgia case because the district court’s
    order did amount to a final judgment in that case. However, Alabama and Florida argue
    that the claims in the cases are sufficiently distinct that extending pendent jurisdiction
    from Georgia over the Alabama, SeFPC, and Apalachicola claims would be
    inappropriate.11 We disagree. Issues in the three contested cases and the Georgia case
    are inextricably intertwined, rendering pendent jurisdiction proper. Even if this Court
    did not have pendent jurisdiction over these claims, this Court would still have
    jurisdiction because the district court’s order amounted to an injunction.
    “Pendent appellate jurisdiction is present when a nonappealable decision is
    inextricably intertwined with the appealable decision or when review of the former
    decision is necessary to ensure meaningful review of the latter.” King v. Cessna
    Aircraft Co., 
    562 F.3d 1374
    , 1379 (11th Cir. 2009) (internal quotation marks omitted).
    The exercise of such jurisdiction is only appropriate in “rare circumstances” so only

    A panel of this court rejected this argument in a January 20, 2010 order accepting
    pendent jurisdiction over the district court’s entire order because “all issues raised by the
    appellants are inextricably intertwined.” Order of Jan. 20, 2010 at 5. (Citing Sierra Club v. Van
    Antwerp, 
    526 F.3d 1353
    , 1359 (11th Cir. 2008); Summit Med. Assocs., P.C. v. Pryor, 
    180 F.3d 1326
    , 1335 (11th Cir. 1999)). We agree with the findings of the panel on this matter.

    “limited factual scenarios” will qualify. 
    Id. at 1379–80.
    Thus, the critical inquiry is
    whether the appealable issue can be resolved without reaching the merits of the
    nonappealable issues. Thomas v. Blue Cross & Blue Shield Ass’n, 
    594 F.3d 814
    , 821
    (11th Cir. 2010).
    Alabama and Florida argue that the appeal of Georgia can be resolved without
    addressing the issues in the other cases. They argue that the district court found that
    Georgia’s request for a reallocation of 34% of the available storage exceeded the
    Corps’ authority because the argument was simply foreclosed by collateral estoppel and
    the preclusive effects of the D.C. Circuit’s Geren decision. Thus, they argue that the
    merits of the Georgia appeal can be determined without considering the underlying
    issues in the other cases.
    Alabama and Florida misread both the district court’s opinion and the opinion
    in Geren. The district court did not, and could not, simply dismiss the Georgia case on
    the basis of collateral estoppel. The Corps’ authority to allocate storage for water
    supply depends on an analysis of both the RHA and the WSA. As noted above, the
    district court held that only two issues were precluded, and neither of them were the
    authority of the Corps under the RHA. In fact, the D.C. Circuit clearly stated that the
    issue of water supply authority in the RHA was not before it. See 
    Geren, 514 F.3d at 1324
    n.4 (“The court, in responding to the Corps’ defense of its approval of the
    36
    Agreement, has no occasion to opine whether the Corps’ previous storage reallocations
    were unlawful.”). Thus, it is clear that the holding in Geren—i.e. that a 22%
    reallocation of storage to water supply constitutes a “major operational change” under
    the WSA—cannot operate as collateral estoppel with respect to the issue of the Corps’
    combined authority under the RHA and the WSA.12
    Thus, the district court did not apply collateral estoppel in granting summary
    judgment against the Georgia Parties and holding that Georgia’s 2000 request exceeded
    the Corps’ authority. Rather, the district court came to an independent conclusion on
    this matter and found that water supply was not an authorized purpose under the RHA.
    
    Tri-State, 639 F. Supp. 2d at 1347
    . This finding was central to the court’s holding in
    all four cases. Ultimately, it is impossible for this Court to rule on the merits of the
    appeal in Georgia without determining whether water supply was an authorized
    purpose of the Buford Project under the RHA. Thus, the issues raised in the various
    appeals are inextricably intertwined and pendent jurisdiction is proper in Alabama,
    SeFPC, and Apalachicola.
    As an alternative basis for jurisdiction in the three cases (other than the Georgia
    case), this Court also has appellate jurisdiction over all of the underlying claims

    infra at Part VI.
    37
    because the district court’s order was an injunction. The order very clearly directs the
    parties to act, imposing a set of directives that, if disobeyed, could subject the parties
    to contempt proceedings. We are granted jurisdiction to review injunctions (or denials
    thereof) by 28 U.S.C. § 1292(a)(1). Alabama and Florida argue that this statute does
    not apply in this case because the district court’s order is not an injunction. Instead,
    they argue, the district court merely set aside the Corps’ actions because they were not
    in accordance with the law, and therefore in violation of the APA. See Citizens to
    Preserve Overton Park, Inc. v. Volpe, 
    401 U.S. 402
    , 413–14, 
    91 S. Ct. 814
    , 822 (1971)
    overruled on unrelated grounds by Califano v. Sanders, 
    430 U.S. 99
    , 105, 
    97 S. Ct. 980
    ,
    984 (1977). This argument is unpersuasive.
    The district court’s order is “a clearly defined and understandable directive by
    the court to act or to refrain from a particular action.” 
    Alabama, 424 F.3d at 1128
    . The
    district court mandated the return of operations to the levels of the mid-1970s by 2012,
    meaning that the Corps was required to set off-peak flows to 600 cfs and only Buford
    and Gainesville were allowed to withdraw any water directly from Lake Lanier (in the
    amounts established in their 1950s contracts). 
    Tri-State, 639 F. Supp. 2d at 1355
    . The
    court gave the Corps explicit instruction on how it was to act in the future. The Corps
    was also prohibited from entering into any new water supply contracts and therefore
    stripped of any discretion on how to allocate storage space for water supply. The
    38
    district court did not refer to its order as an injunction, but the district court’s intention
    in this regard is irrelevant. See Sierra Club v. Van Antwerp, 
    526 F.3d 1353
    , 1358–59
    (11th Cir. 2008) (utilizing a functional analysis to determine that the district court order
    was an injunction in spite of the district court’s specific denial in this regard); United
    States v. Gila Valley Irrigation Dist., 
    31 F.3d 1428
    , 1441 (9th Cir. 1994) (“In
    determining whether or not an order is appealable under § 1292(a)(1), the courts do not
    look to the terminology of the order but to its substantial effect.”) (citation omitted).
    The district court’s order was also sufficiently definite to be enforced via
    contempt proceedings. See 
    Alabama, 424 F.3d at 1128
    . Federal Rule of Civil Procedure
    65(d) requires that an injunctive order “state its terms specifically” and “describe in
    reasonable detail . . . the act or acts restrained or required.” Alabama and Florida do not
    question the definitive nature of the order in 2012. Rather, they focus on the court’s
    directives in the interim period: “the parties may continue to operate at current water-
    supply withdrawal levels but should not increase those withdrawals absent the
    agreement of all other parties to this matter.” 
    Tri-State, 639 F. Supp. 2d at 1355
    .
    Alabama and Florida argue that the order does not state with specificity the amount of
    water that each of the localities may withdraw. However, this is of no moment because
    no party would dare risk being held in contempt for violating the court’s order by
    exploiting any of these ambiguities. The practical effect of this order makes it such that
    39
    none of the localities would withdraw any more water than they did before the order
    was issued. Furthermore, it is irrelevant whether this injunction was defective under
    Rule 65(d) because this Court could still exercise jurisdiction under § 1291(a)(1) over
    a defective injunction. See Int’l Longshoremen’s Ass’n, Local 1291 v. Phila. Marine
    Trade Ass’n, 
    389 U.S. 64
    , 76, 
    88 S. Ct. 201
    , 208 (1967). The proper remedy in such a
    case would be to vacate the injunction and remand the case to the district court.13
    Because pendent jurisdiction is proper in this case and because the district court order
    is an injunction, this Court possesses appellate jurisdiction and will consider the merits
    of the issues raised by the parties.
    B.      Final Agency Action in Alabama, SeFPC, and Apalachicola
    The Corps and the Georgia Parties argue that the district court did not have
    jurisdiction to hear the Alabama case, the SeFPC case, and the Apalachicola case
    because the Corps had not taken a final agency action, as required by the APA for
    judicial review. See 5 U.S.C. § 704. In these three cases, Appellees challenge what they
    have characterized as the “de facto reallocations”—the temporary water withdrawals
    13
    Alabama and Florida also argue that the district court order is not appealable
    because it is conditional. As a factual matter, this position is incorrect. The court’s order, though
    stayed for three years, does not depend on the happening of a specific event to go into operation.
    Just the opposite; the injunction was final when issued and would take effect without the
    occurrence of any contingency whatsoever. Moreover, a portion of the order forbids the parties
    from increasing withdrawals and the Corps from entering into new contracts without the consent
    of all of the parties to the litigation. This is a negative injunction which was not stayed until 2012
    and took effect immediately.
    40
    the Corps has allowed and continues to allow. The Corps argues that it never made a
    formal reallocation of storage in the reservoir. Instead, it argues that it accommodated
    water supply under ad hoc arrangements with the localities and a series of agreements
    among all three States, while launching multiple, ultimately futile, attempts to reach a
    long-term solution to the issue. The parties all concede that the denial of Georgia’s
    water supply request was a final agency action and that the district court possessed
    jurisdiction over the Georgia case. With respect to the other three cases, we conclude
    that there was no final agency action, and the district court therefore lacked jurisdiction
    to review the claims.
    The APA states that “final agency action for which there is no other adequate
    remedy in a court [is] subject to judicial review.” 5 U.S.C. § 704. The APA defines
    “agency action” as including “the whole or a part of an agency rule, order, license,
    sanction, relief, or the equivalent or denial thereof, or failure to act.” 5 U.S.C. §
    551(13). Because the definition of action under the APA is so broad, the critical inquiry
    is whether the action is final. Whitman v. Am. Trucking Ass’ns, 
    531 U.S. 457
    , 478, 
    121 S. Ct. 903
    , 915 (2001) (“The bite in the phrase ‘final action’ . . . is not in the word
    ‘action,’ which is meant to cover comprehensively every manner in which an agency
    may exercise its power. . . . It is rather in the word ‘final’ . . . .”) (citations omitted).
    The test for finality involves two steps:
    41
    First, the action must mark the “consummation” of the agency’s
    decisionmaking process . . . —it must not be of a merely tentative or
    interlocutory nature. And second, the action must be one by which rights
    or obligations have been determined, or from which legal consequences
    will flow.
    Bennett v. Spear, 
    520 U.S. 154
    , 177–78, 
    117 S. Ct. 1154
    , 1168 (1997) (internal
    quotation marks and citations omitted).
    We analyze whether the Corps’ actions were final by using the two-step
    Bennett test. The Corps contends that it has not consummated its decisionmaking
    process because it has not made any final decisions on how to allocate water storage
    at Buford. The Corps notes that it never made any permanent water supply storage
    allocations and has not published any implementation guidelines. As evidence that
    no decisionmaking process has been consummated, the Corps notes that it has not
    performed the cost analyses or prepared the written reports required by the WSA,
    the Corps’ internal guidelines, and the National Environmental Policy Act to make
    permanent reallocations. The Corps asserts that it attempted to start the
    decisionmaking process in 1989 with its draft PAC Report, which included a draft
    manual for operations in the ACF basin, but that the report was abandoned prior to
    its completion as part of the negotiations in the Alabama litigation.
    The “de facto reallocations” do not meet the first prong of the Bennett test.
    42
    They are based on contracts that have all expired and water withdrawals that have
    been extended on the basis of multi-party agreements and court orders. The various
    contracts that the Corps entered into with Gwinnett, the ARC, and the Cities of
    Gainesville and Cumming all specified their interim nature, expired in 1990, and did
    not purport to provide any permanent right to storage in Lake Lanier. As the Corps
    notes, these contracts are long expired now and are not themselves being challenged
    in this litigation.
    What is being challenged is the continuous withdrawal of water from the
    Buford Project over the last forty years. Appellees assert that the Corps has utilized
    a practice of entering into temporary agreements in order to avoid the appearance of
    consummating its decisionmaking process. “[A]s a general matter, . . . an
    administrative agency cannot legitimately evade judicial review forever by
    continually postponing any consequence-laden action and then challenging federal
    jurisdiction on ‘final agency action’ grounds.” Nat’l Parks Conservation Ass’n v.
    Norton, 
    324 F.3d 1229
    , 1239 (11th Cir. 2003) (citing Cobell v. Norton, 
    240 F.3d 1081
    , 1095 (D.C. Cir. 2001)). The record in this case demonstrates that the Corps
    has not acted to avoid judicial review. Rather, the factual history of this case
    indicates that the Corps has made sincere efforts to effectuate permanent water
    supply allocations but has been thwarted by the litigation process.
    43
    The Corps has been attempting to reach a final decision on water storage
    allocations in the Buford Project since at least the mid-1980s, when it became aware
    that a permanent determination of water supply needs was vital. The agency
    concluded at the time that it was best to wait until the MAAWRMS was complete
    before making such a determination and to enter into interim contracts that would
    expire in 1990. Once the study was complete, the Corps embarked on the process of
    issuing the PAC Report and permanently reallocating certain amounts of storage to
    water supply—after first proposing and receiving Congressional authorization (but
    not funding) to build a reregulation dam. However, the Corps’ plan to issue the PAC
    was derailed by developments in the Alabama case.
    In 1992, the parties agreed to a stay and entered into a Memorandum of
    Agreement, which required that the Corps withdraw the PAC and prohibited it from
    entering into any new contracts. Memorandum of Agreement By, Between, and
    Among the State of Alabama, the State of Florida, the State of Georgia, and the
    United States Department of the Army 2 (Jan. 3, 1992). The Corps retained
    permission to continue to accommodate current withdrawal levels. In the
    memorandum, the parties agreed to conduct a Comprehensive Study, stating that
    “during the term of the Comprehensive Study, it is premature for the Army to
    commit, grant or approve any reallocation, allocation, or apportionment of water
    44
    resources to service long-term future water supply.” 
    Id. Thus, during
    the duration of
    the term of the Memorandum of Agreement, the Corps was restricted from moving
    toward taking final agency action due to the terms agreed upon by the parties.
    The same held true during the period of enforcement of the ACF Compact,
    the joint resolution that the three states agreed to and Congress ratified in 1997,
    which replaced the Memorandum of Agreement. The ACF Compact created an ACF
    Basin Commission charged with the power “to establish and modify an allocation
    formula for apportioning the surface waters of the ACF Basin among the states of
    Alabama, Florida and Georgia.” 111 Stat. at 2222. The Compact specified that
    parties could continue withdrawing water but that no vested rights would be granted
    until the Commission adopted an allocation formula. 
    Id. at 2223–24.
    The Compact
    provided that the Army Corps of Engineers “shall cooperate with the ACF Basin
    Commission in accomplishing the purposes of the Compact and fulfilling the
    obligations of each of the parties to the Compact regarding the allocation formula.”
    
    Id. at 2225.
    Much like the Memorandum of Agreement before it, the ACF Compact,
    which remained in effect until 2003, restricted the Corps’ ability to consummate a
    decisionmaking process on its water allocation policy. Thus, from 1992 to 2003, the
    Corps was operating under agreements signed by all three states that denied it the
    ability to make any permanent water supply allocations.
    45
    By the time the negotiations in the Alabama case fell apart in 2003, the
    Georgia Parties, the Corps, and SeFPC had entered into a settlement agreement in
    SeFPC. In pertinent part, the agreement set forth a process for entering into water
    supply contracts that could become permanent reallocations of storage. Evaluation
    of the legality of the settlement agreement in the D.C. district and circuit courts was
    delayed for several years by a preliminary injunction entered by the Northern
    District of Alabama. In March 2005, while the injunction was still in effect, the
    Corps filed a notice in the Alabama litigation that it intended to proceed with
    updating the water control plans and manuals for the ACF Basin. In response,
    Alabama’s Congressional delegation sent a letter to the Corps stating its opposition
    to such actions during the pendency of the litigation, and the Corps abandoned its
    plans.
    This Court vacated the Alabama court’s injunction in late 2005 and the Corps
    informed the states that it considered the “relevant litigation” concluded and would
    proceed to update the water control manuals for the ACF Basin. However, on
    remand, the Alabama district court sent the parties into settlement negotiations, and
    the Corps again agreed to delay the update.
    The SeFPC settlement was struck down in 2008 and never took effect. The
    Corps argues that it began the process of updating its operating manuals for the
    46
    ACF basin almost immediately after the settlement agreement was invalidated. The
    Corps also issued a legal memorandum on its authority to allocate water storage at
    Buford, the 2009 Stockdale Memorandum. However, the district court deemed the
    2009 Stockdale Memo to be a litigation document and not part of the administrative
    record. The district court issued its summary judgment order in this case on July 17,
    2009, and the Corps asserts that this order once again thwarted it in its attempts to
    consummate the decisionmaking process. The Corps states that “every single day
    since 1990 the Corps was either operating under an agreement that barred it from
    formally taking any steps to reallocate storage, or was actively engaged in a process
    that could have led to a final agency action reallocating storage.” The historical
    sequence of events supports the veracity of this claim.
    This Court has accepted legal and practical barriers to administrative action
    as legitimate explanations for agency inaction.14 See Nat’l 
    Parks, 324 F.3d at 1238
    ,
    14
    The Corps cites Home Builders Ass’n of Greater Chicago v. United States Army
    Corps of Engineers, 
    335 F.3d 607
    , 616 (7th Cir. 2003), for the proposition that the circuits have
    reached a consensus that agency delay must be “egregious” for it to be considered the
    consummation of the decisionmaking process. This proposition is not entirely accurate. Home
    Builders was evaluating the second prong of the Bennett test, not the first, when it made this
    statement. Thus, the Seventh Circuit was referring to the manner in which agency inaction
    determines the rights or obligations of the parties, not whether agency inaction constitutes the
    consummation of the decisionmaking process. The cases from other circuits cited by that court
    also deal with the manner in which agency action affects the rights of the parties. There may be
    some overlap between the two prongs of the analysis, but we need not decide whether the Home
    Builders “egregious” threshold applies also to evaluating delays with respect to the first prong. In
    this case, the Corps is able to demonstrate that its actions were not only not egregious but also
    understandable due to the circumstances in this case. Thus, its argument that the first prong of
    47
    1239 (holding that the National Parks Service’s delay in implementing a
    management plan was excusable in part because a judicial order and a legislative
    mandate had prevented it from taking action). The courts have expressed a
    legitimate concern for agency avoidance of judicial review through intentional
    inaction. 
    Id. at 1239.
    In this case, however, the lack of a definitive allocation of
    storage for water supply is explained by factors beyond the agency’s control, rather
    than the Corps’ inaction.
    Appellees argue that the Corps has attempted to avoid judicial review of its
    management of the Buford Project, but they offer almost no evidence to support this
    contention. Alabama and Florida point out that the Corps, though required by court
    order not to enter into any new contracts, was not required to continue to allow the
    parties to withdraw water from the project. This argument misses the point. That the
    Corps chose to continue to permit water supply withdrawals sanctioned by the
    multi-party agreements does not demonstrate that the Corps effectuated a policy in
    regard to water supply and was attempting to avoid a judicial review of this policy.
    The states also note that the Corps had seven years since the time of the expiration
    of the agreements in 2003 to undertake a formal action. As stated above, the Corps
    attempted on multiple occasions after 2003 to begin the process of making final
    Bennett was not met is persuasive even without support from Home Builders.
    48
    decisions on water allocations, but it was consistently thwarted by the litigation
    process. The Corps’ two statements to the parties in 2005 that it intended to move
    forward with updating the water control manuals, the settlement agreement in
    SeFPC, which was struck down in 2008, and the 2009 Stockdale Memorandum,
    demonstrate that the Corps intended to move forward in consummating a
    decisionmaking process after 2003 but could not. Appellees point to no specific
    final actions on the part of the Corps and there is insufficient evidence to conclude
    that the agency has attempted to avoid judicial review via incremental changes in
    operational policy. Thus, Appellees are unable to meet the first prong of the Bennett
    analysis.
    The Corps’ current operations of the Buford Project also do not meet the
    second prong of the Bennett test because the Corps’ alleged “de facto allocations”
    are not actions “by which rights or obligations have been determined, or from which
    legal consequences will 
    flow.” 520 U.S. at 178
    , 117 S. Ct. at 1168 (internal
    quotation marks omitted). Current water supply withdrawals have taken place under
    the “live and let live” and other similar provisions in the stays, the Memorandum of
    Agreement, and the ACF Compact. These provisions, like the interim contracts that
    preceded them, have clearly stated the temporary nature of the allocations being
    made. As outlined above, the Corps has not had the opportunity to engage in a
    49
    determination of rights or obligations due to the constraints imposed on it by the
    specific circumstances of the ongoing litigation. While it is true that access to water
    has been affected by the Corps’ water supply allocations, as Appellees argue, that
    fact does not demonstrate that any future rights have been determined.15 Appellees
    are simply unable to produce evidence of such a determination.
    Because there has been no final agency action in the Alabama, SeFPC, and
    Apalachicola actions, the district court lacked jurisdiction over these claims.
    Therefore, we vacate the district court’s rulings in this regard and remand to the
    Corps to make final determinations pertaining to its current policy for water supply
    storage allocation.16
    15
    Even if the past withdrawals of water could be deemed sufficient to satisfy the
    second prong (notwithstanding the absence of any determination of future rights or
    obligations)—a matter we need not decide—there would still be no final agency action because
    Appellees have failed to satisfy Bennett’s first prong.
    16
    Alabama and Florida argue that this issue was decided by this Court and that
    collateral estoppel bars the Corps and the Georgia Parties from making this claim. In our
    consideration of the appeal in Alabama, we indicated in a footnote that some of the Corps’
    storage allocations were final agency actions under the 
    APA. 424 F.3d at 1131
    & n.19. However,
    this issue lacks preclusive effect because it was not actually litigated in Alabama. See In re Held,
    
    734 F.2d 628
    , 629 (11th Cir. 1984).
    In Alabama, the Georgia Parties argued that the complaint was moot as a result of the fact
    that Alabama challenged the PAC Report, a report which had long since been withdrawn by the
    Corps. We dismissed the mootness argument by noting that Alabama was challenging other
    Corps actions, namely the ongoing reallocations of storage capacity. With respect to such other
    Corps actions, this court in footnote 19 commented that Alabama had identified such actions as
    final agency actions. It is possible that this footnote was not merely a comment on what Alabama
    had said, but an implied acknowledgment that on-going reallocations of storage capacity were
    indeed final agency actions. Even if the latter, this court’s statement was a passing, bald
    50
    Part II.        Georgia’s 2000 Request: The Corps’ Water Supply Authority
    Under the RHA
    With respect to the merits, we turn first to the appeal in the Georgia case. This
    statement with no discussion at all, and was not the product of an actually litigated issue.
    Accordingly, the statement does not have collateral estoppel effect. See 
    id. The parties
    did not
    brief the issue and there is no evidence that the question of final agency action was litigated at
    all. The matter was addressed as an afterthought to the rejection of a wholly separate, tangential
    argument. Having heard full and thorough argument on the matter by the parties, we conclude
    that the action alleged in these appeals was not final.
    Even if collateral estoppel did apply and the district court did have jurisdiction, we would
    still be required to vacate the order and remand the case to the Corps, because of the numerous
    errors of the district court. Although we need not enumerate each error, we note the overarching
    error in conducting de novo factfinding of issues that must be considered by the Corps in the first
    instance. In an administrative case, the Supreme Court has said, “[t]he reviewing court is not
    generally empowered to conduct a de novo inquiry into the matter being reviewed and to reach
    its own conclusions based on such an inquiry.” Fla. Power & Light Co. v. Lorion, 
    470 U.S. 729
    ,
    744, 
    105 S. Ct. 1598
    , 1607 (1985). The wisdom of that decree is apparent in this case. The Corps
    has yet to undertake any final, well-reasoned actions in regard to current water supply
    withdrawals at the Buford Project. As a result, the judicial record in this case is incomplete.
    Because this record is incomplete, the district court undertook on its own to perform calculations
    to determine the percentage of Lake Lanier’s storage space currently being allocated to water
    supply. As part of this determination, the court substituted its judgment for that of the Corps on a
    number of highly technical matters better left to the expertise of the agency. First and foremost,
    the court rejected several determinations by the Corps of the baseline amount of water available
    for downstream water withdrawal as a byproduct of power generation. Second, it used data from
    expired contracts even though there were no binding commitments, rather than using figures of
    actual water withdrawals, allegedly compounding this mistake by double-counting the City of
    Gainesville’s withdrawals. Finally, the court took no account of return flows even though the
    return of those flows directly to the lake would offset the effect on the power interest. The
    expertise of the Corps renders it better equipped to handle such questions than a court. The
    district court should not have usurped the agency’s fact-finding role. Without identifying each
    error of the district court, suffice it to say that the district court’s overearching error in engaging
    in de novo fact-finding would have required remand even if there had been final agency actions.
    Moreover, the district court also erred in failing to recognize that water supply for the
    Atlanta area was an authorized purpose of the RHA. See Part II, infra. The fact that water supply
    is an authorized purpose of the Project has the potential to cause significant changes in the
    relevant calculations, and thus constitutes an independent basis for requiring a remand to the
    Corps for de novo reconsideration.

    Court previously summarized Georgia’s 2000 request of the Corps as follows:
    1.     Allow municipal and industrial withdrawals from Lake Lanier to
    increase as necessary to the projected annual need of 297 mgd in
    2030;
    2.     Increase the water released from the Buford Dam sufficiently to
    permit municipal and industrial withdrawals in the Chattahoochee
    River south of the dam to be increased as necessary to the
    projected annual need of 408 mgd in 2030;
    3.     Enter into long-term contracts with Georgia or municipal and
    industrial water users in order to provide certainty for the
    requested releases;
    4.     Ensure that sufficient flow is maintained south of the Buford Dam
    to provide the requisite environmental quality—that is, assimilate
    discharged wastewater; and
    5.     Assess fees on the municipal and industrial water users in order to
    recoup any losses incurred by a reduction in the amount of
    hydropower generated by the dam as a result of the increased
    withdrawals or releases.
    
    Georgia, 302 F.3d at 1247
    –48.
    The parties agree that the Corps’ rejection of Georgia’s 2000 request
    constituted a final agency action, of which both the district court and this Court
    have jurisdiction to review. Central to the Corps’ rejection was the Corps’
    conclusion that water supply was not an authorized purpose of the Buford Project.
    We now hold that the Corps erred in drawing this conclusion. The text of the 1946
    Rivers and Harbors Act— specifically, the Newman Report, whose language is
    52
    incorporated into the statute—clearly indicates Congress’ intent to include water
    supply as an authorized purpose in the Buford Project.
    The 1945 and 1946 Rivers and Harbors Acts authorized the building of the
    Buford Project and serve as the baseline for the Corps’ authority to operate the
    dam.17 The Georgia Parties contend that the district court seriously erred in its
    interpretation of the scope of its authority under the Act and neglected to note the
    specific authorization for water supply in the statute. The district court rejected this
    argument and held that water supply was only intended to be an incidental benefit of
    other operations and that the RHA did not authorize any storage for water supply in
    Lake Lanier.
    The RHA authorized the development of the ACF Basin “in accordance with
    the report of the Chief of Engineers, dated May 13, 1946.” 60 Stat. at 635. The
    Chief of Engineers Report incorporated the Division Engineer’s Report—i.e. the
    Newman Report. Thus, the statute fully incorporated the terms of the Newman
    Report. The Newman Report specifically modified the recommendations of the Park
    Report—the foundational report for the 1945 RHA—by proposing the building of a
    17
    The 1945 RHA is less pertinent to the analysis than the 1946 Act because the final
    plans for the Buford Project, most notably its location and size, were not determined until the
    writing of the Newman Report, which post-dated the 1945 statute. Therefore, the majority of the
    discussion in this opinion centers on the 1946 RHA and any mention of the RHA without a
    specific year is a reference to the 1946 statute.

    single multi-purpose reservoir upstream of Atlanta instead of three separate
    reservoirs. One advantage of such a move was that the new dam could more easily
    accommodate water supply needs.
    As the Newman Report made clear, the dam was designed with water supply
    specifically in mind. At times, water supply was even to be accommodated at the
    expense of optimal hydropower generation. The Newman Report explained:
    If operated at 100-percent load factor, the Buford development
    would provide a minimum continuous flow of 1,634 second-feet,18 more
    than sufficient for the water needs of the Atlanta area. However, if the
    plant were operated on peak loads, as it should be for maximum power
    value, it would be shut down during week ends and week-day off-peak
    periods; as a result of those shut-downs, the minimum flow at Atlanta
    from the area below Buford Dam would be only about 50 second-feet.
    Under the same conditions of operation, the maximum flow at Atlanta at
    the daily peak of the load would be over 3,000 second-feet. In order to
    meet the estimated present needs of the city, and to prevent damage to
    fish, riparian owners, and other interests by complete shutdowns of the
    Buford plant during the daily and week-end off-peak periods, varying
    flows up to a maximum of 600 second-feet should be released from
    Buford so as to insure at all times a flow at Atlanta not less than 650
    second-feet. This flow could be used to operate a small generator to
    generate off-peak power as secondary energy, reserving the remaining
    storage for peak operation. This minimum release may have to be
    increased somewhat as the area develops. This release at Buford would
    not materially reduce the power returns from the plant, and would not
    affect the power benefits from plants downstream; the benefits to the
    Atlanta area from an assured water supply for the city and Georgia Power
    Co.’s steam plant would outweigh any slight decrease in system power
    value.
    18
    “Second-feet” is another way of saying cfs.
    54
    Newman Report ¶ 80.
    There are several critical provisions in this paragraph of the report. First,
    Congress contemplated that “the estimated present needs of the city” for water
    supply would be met by the initial Project by “insur[ing] at all times a flow at
    Atlanta not less than 650 second-feet.” 
    Id. Indeed, Congress
    provided in the
    construction of the project that, in addition to the two large turbines, there would be
    “a small generator to generate off-peak power as secondary energy, reserving the
    remaining storage for peak operation.” 
    Id. This small
    turbine was constructed for
    the sole purpose of providing off-peak releases of 600 cfs (without completely
    losing the value of these releases for power generation). If operated for maximum
    power value, the dam would be shut down during off-peak hours and would release
    no water, limiting water flow at Atlanta to a rate of 50 cfs. Such an operational
    scheme would not require a small turbine at all. Thus, the design of the project and
    the operational scheme were influenced by water supply concerns.
    Second, the minimum flow was provided for notwithstanding the clear
    Congressional intent that it would be at the expense of “maximum power value.” 
    Id. Congress recognized
    that shutting down all water releases during off-peak hours
    would create an insufficient flow in the river downstream at Atlanta to meet the
    city’s water supply needs. Therefore, even though Congress recognized that there
    55
    would be some detriment to power generation, it nevertheless provided for a
    minimum flow of 650 cfs at Atlanta. The Newman Report, and thus the authorizing
    legislation itself, explicitly stated as much. The legislation provided, in connection
    with the initial minimum release requirement and the contemplated increases
    thereof, that “the benefits to the Atlanta area from an assured water supply for the
    city . . . would outweigh any slight decrease in system power value.” 
    Id. Third, Congress
    recognized that “[t]his minimum release may have to be
    increased somewhat as the area develops.” 
    Id. Indeed, in
    the immediately preceding
    paragraph, the authorizing legislation considered the growing need for water supply
    to the metropolitan area over a future 19-year period and spoke of increasing off-
    peak releases to accommodate the water supply needs of the Atlanta area in 1965.
    That future water supply need was estimated to require a river flow at Atlanta of
    800 cfs. 
    Id. ¶ 79.
    Thus, the original authorizing legislation expressly contemplated a
    very substantial increase in the operation of the Buford Project to satisfy the water
    supply needs of the Atlanta area (i.e., from 650 cfs to 800 cfs in the river flow at
    Atlanta).19
    19
    The language of the paragraph reads:
    Local interests state that, in 1941, 70 second-feet of water were required
    for domestic and industrial purposes at Atlanta, and 415 second-feet for
    condensing water at the Atkinson steam-electric plant of the Georgia Power Co.
    on the river bank near mile 299.5; that an additional unit since installed has raised
    56
    In light of the foregoing statutory language, and particularly Congress’ intent
    that the Corps should have authority to accommodate the Atlanta area’s water
    supply needs at the expense of some detriment to “system power value,” we cannot
    conclude that Congress intended for water supply to be a mere incidental benefit.
    By definition, one purpose that is to be accomplished to the detriment of another
    cannot be incidental.20 Thus, the language of Sections 79 and 80 clearly indicates
    that Congress intended for water supply to be an authorized, rather than incidental,
    use of the water stored in Lake Lanier.21
    the total requirement of the steam plant to 565 second-feet; and that the total
    requirement for the Atlanta area for 1965, based on a population of 600,000 at that
    time, will be 600 second-feet for condensing water, 120 second-feet for municipal
    supply, and 80 second-feet of raw water for industries—a total of 800 second-feet.
    Newman Report ¶ 79. Thus, as of the time of the 1946 statute, it seems that domestic and
    industrial water supply needs at Atlanta required a minimum river flow at Atlanta of 635 cfs (70 +
    565). And the authorizing legislation contemplated that 19 years hence, in 1965, that requirement
    would increase to 800 cfs, a substantial increase. In evaluating the extent of the Corps’ authority
    to satisfy the water supply needs of the Atlanta area, it is clearly relevant that Congress explicitly
    contemplated this substantial increase in water supply. The district court’s injunction, limiting off-
    peak releases to 600 cfs, is obviously inconsistent with this contemplated increase in water supply.
    The 600 cfs level was the initial mandate in the authorizing legislation, 
    id. ¶ 80,
    and Congress
    explicitly contemplated substantial increases. 
    Id. ¶¶ 79,

    The adjectival forms of the term “incident” can mean “subordinate to something
    of greater importance; having a minor role” or “dependent upon, subordinate to, arising out of, or
    otherwise connected with.” Black’s Law Dictionary 830 (9th ed. 2009). The superiority of water
    supply to hydropower in certain instances demonstrates that it could not have been a purely
    subordinate purpose. Likewise, the superiority of water supply under certain circumstances
    demonstrates that it was not meant to be fully dependent upon hydropower.
    21
    In Alabama, we stated, “Lake Lanier was created for the explicitly authorized
    purposes of flood control, navigation, and electric power 
    generation.” 424 F.3d at 1122
    . We went
    on to say, “the Corps has historically maintained that water supply use is an ‘incidental benefit’
    57
    Appellees argue that the Newman Report’s references to water supply as
    “incidental” demonstrates that water supply was not an authorized purpose of the
    Buford Project. This is an attractive proposition due to its simplicity, but the context
    of these references undermines this claim. The language in question is as follows:
    The city of Atlanta and other local interests in that area have strongly
    urged that the Roswell development, 16 miles upstream of Atlanta, or
    one or more other reservoirs above Atlanta, be provided first, in order to
    meet a threatened shortage of water, during low-flow periods, for
    municipal and industrial purposes. If the regulation storage reservoir
    required for the economical operation of the proposed developments
    below Columbus could be located above Atlanta, it would greatly
    increase the minimum flow in the river at Atlanta, thereby producing
    considerable incidental benefits by reinforcing and safeguarding the
    water supply of the metropolitan area.
    Newman Report ¶ 68 (emphasis added). We conclude that this single reference to
    water supply as an “incidental benefit” was an explanation for why the dam would
    be built above Atlanta and was not meant to confer a subordinate status.
    The Corps in the Park Report proposed the construction of three dams at
    flowing from the creation of the reservoir.” 
    Id. These statements
    were mere dicta. The issue on
    appeal in Alabama was whether the district court’s enjoining of the proceedings in the D.C.
    District Court (halting the finalization of the settlement agreement in SeFPC) was proper. The
    parties did not brief the issue of the Corps’ water supply authority and this Court gave the topic
    no discussion, save for that quoted above. Thus, these statements were not the product of actual
    litigation, were not a “critical and necessary part of the judgment,” and have no preclusive effect
    on the decision in this case. See Christo v. Padgett, 
    223 F.3d 1324
    , 1339 (11th Cir. 2000)
    (quotation omitted). The current appeal has allowed the Court to scrutinize more closely the
    Corps’ water supply authority. After a full analysis of the language and legislative history of the
    RHA and consideration of the arguments of the parties, we conclude that Congress intended for
    water supply to be included as an authorized purpose of the Buford Project.
    58
    Cedar Creek, Lanier, and Roswell. 
    Id. The Corps
    subsequently determined in the
    Newman Report that the system of dams in the ACF Basin would operate
    substantially more efficiently if one large dam was built instead. The agency
    decided to locate the dam at Buford, approximately 47 miles upstream of Atlanta.
    Paragraph 68 was an explanation for why the Corps deemed it beneficial to build
    the dam at this location; the explanation: water supply. An upstream location would
    allow the Corps to secure Atlanta’s water supply as an incident of the other
    authorized purposes. That is to say that the aim of benefitting water supply could be
    accomplished without any significant detriment to hydropower, navigation, or flood
    control. The report stated that the revised location and size of the dam and reservoir
    would result in “greatly increase[d] . . . minimum flow in the river at Atlanta,
    thereby . . . reinforcing and safeguarding the water supply of the metropolitan area.”
    
    Id. This benefit
    would be incidental to power generation because the water
    constituting the river flow at Atlanta would have generated power as it passed
    through the generators. There is no indication that the use of the word “incidental”
    in Paragraph 68 was meant to describe the importance of water supply to the project
    or even the importance of water supply vis-a-vis the other project purposes.
    This reading is further supported by the phrase “safeguarding the water
    supply of the metropolitan area.” 
    Id. The fact
    that references to incidental benefits
    59
    and the safeguarding of water supply were made in the same breath demonstrates
    that the Newman Report did not use the term as an indication of a subordination of
    the importance of water supply. Instead, the “safeguarding” language of Paragraph
    68 indicates the critical nature of the water supply purpose to the project. In fact, the
    Newman Report went on to describe the importance of the Buford Project for the
    protection and assurance of Atlanta’s water supply on at least four other occasions.
    
    Id. ¶¶ 73
    (“would ensure an adequate water supply for the rapidly growing Atlanta
    metropolitan area”), 80 (“insure at all times a flow at Atlanta”) (“the benefits to the
    Atlanta area of an assured water supply for the city”), 100 (“would ensure an
    adequate municipal and industrial water supply for the Atlanta area”). Congress’
    focus on the need to ensure the Atlanta area’s water supply serves as strong
    evidence of the primary role given to water supply in the project.
    The only other reference in the authorizing legislation to water supply as
    incidental appears in the Newman Report at Paragraph 100.22 There, the final
    22
    The language of this paragraph reads:
    The foregoing results cannot be secured by the plants below Columbus
    proposed herein unless a considerable storage be provided upstream to increase
    the minimum regulated flow and the firm capacities at those plants; without such
    upstream storage, the developments would not be economically justified. The best
    development for that purpose is that at Buford proposed herein. Provision of that
    development as part of the system would increase the minimum monthly flow at
    the Upper Columbia site from about 1,300 second-feet to 6,040 second-feet, with
    a corresponding increase at the Junction site. It would greatly increase both the
    60
    sentence of the paragraph begins with the word “incidentally” and lists several
    project benefits that would not significantly harm other project purposes. One of the
    listed benefits is flood control, which Appellees concede is an authorized purpose.
    This use of the term “incidentally” cannot be construed to mean that water supply
    was intended to be a subordinate use because flood control is referred to in the same
    manner in the sentence. This fact is further illustrated by yet another reference to the
    protection of water supply in the same sentence—“would ensure an adequate
    municipal and industrial water supply for the Atlanta area.” 
    Id. ¶ 100.
    Again, as in
    Paragraph 68, the meaning conveyed in Paragraph 100 is a description of how the
    several authorized purposes could be accomplished harmoniously and the manner in
    which all were better served by locating the project at Buford. For these reasons,
    and especially because of the clear language in Paragraphs 79 and 80 of the
    quality and quantity of the energy output at existing plants above Columbus. It
    would simplify the reregulation of flows at Junction to provide a more adequate
    continuous flow at all times in the Apalachicola River for navigation. Without
    Buford, about 4,000,000 cubic yards of excavation would be required in the
    Apalachicola River below Junction to provide a channel 9 feet deep; with Buford,
    the excavation required would be reduced to about one-half that amount.
    Incidentally, it would ensure an adequate municipal and industrial water supply
    for the Atlanta area, would produce large benefits in the way of recreation, fish
    and wildlife conservation, and similar matters, and would, with the added flood-
    control storage proposed herein, contribute to the reduction of floods and flood
    damages in the basin below.
    
    Id. ¶ 100
    (emphasis added).
    61
    authorizing legislation, we do not read the sparse use of the term “incidental” as
    indicative of the status of water supply as an authorized use vel non.
    Appellees argue that the original project did not contemplate storage in Lake
    Lanier for water supply and that this is an indication that Congress did not intend
    for water supply to be an authorized purpose. We disagree. The lack of storage
    allocation for water supply sheds no light on the intentions of Congress. No storage
    allocation was specified for navigation in the Newman Report even though
    navigation is universally accepted as an authorized purpose of the Buford Project.
    See H.R. Doc. No. 80-300, Letter from Lieutenant General R.A. Wheeler, Chief of
    Engineers, ¶ 11(d). Furthermore, no storage was needed at the time for water supply.
    Almost all of the Atlanta area’s water supply requirements could be met at the time
    as an incident to, or byproduct of, the generation of power. Thus, the lack of initially
    allocated storage for water supply is not at all inconsistent with the Congressional
    intent that water supply was an authorized purpose.
    For the same reason, we believe that the fact that the localities were not asked
    initially to contribute to the costs of the project is of no moment in determining
    Congress’ intent with respect to water supply authorization. Georgia, in 1946, did
    not require a significant amount of water beyond that which was provided by
    normal project operations for power generation, so a request for state contribution to
    62
    the project would not have made sense. It would have meant asking the state to pay
    for a service that the Corps could provide essentially without cost. Moreover, at that
    time, Atlanta’s current water supply usage required a flow of the river at Atlanta of
    635 cfs.23 Even “[d]uring the extremely low-flow month of October 1941, the
    average flow for the month was 493 second-feet, and the minimum daily flow [was]
    422 second-feet.” 
    Id. ¶ 79.
    In other words, before the Buford Dam was built, the
    river was providing the water supply needs of the Atlanta area. The requirement in
    the legislation that the Corps make releases “so as to [e]nsure at all times a flow at
    Atlanta not less than 650 second-feet,” 
    id. ¶ 80,
    merely provided water supply
    roughly commensurate to that which the river was already providing. It is not likely
    that the Corps or Congress would have thought it appropriate to charge Atlanta for
    construction costs of a project that merely replaced its currently available water
    supply.
    The Corps could potentially have asked Georgia to pay on the basis of future
    water supply needs that would affect project operations, but it was not at all clear
    23
    See Newman Report ¶ 79 (“70 second-feet of water were required for domestic
    and industrial purposes at Atlanta.” In addition, the Atkinson steam-electric plant had recently
    installed an “additional unit . . . [that] raised the total requirement of the steam plant to 565
    second-feet.” The two requirements total 635 cfs.).
    63
    how much water would be needed in the future.24 After all, it would be almost 30
    years after the Newman Report before the Corps would sign its first water supply
    contract— excluding the small relocation contracts made as compensation for
    inundating the intakes of Gainesville and Buford. Divining the value of water
    supply to the localities in the future would have resulted in speculative and
    potentially misleading results.25 Similarly, the fact that in its cost-benefit analysis,
    the Newman Report did not assign a particular dollar amount to water supply is not
    an indication that it was not authorized because the benefits of water supply were
    indeterminate at the time.26
    24
    In 1949, the Corps stated that the Buford Project’s assurance of Atlanta’s water
    supply would be a “real benefit” but that it was premature to attempt a specific calculation of that
    benefit. Definite Project Report ¶ 124.
    25
    The 1937 Flood Control Act (“FCA”) allowed states and localities to request that
    the Corps, prior to construction of a flood control project based on a given set of plans, modify
    those plans for the inclusion of storage for water supply. The act required that localities pay the
    full cost of such increased storage capacity. Alabama and Florida argue that it is inconceivable, in
    light of the framework of the FCA, the only general statutory grant of water supply authority to
    the Corps in 1946, that Congress would authorize water supply storage in Lake Lanier without
    requiring contribution from the localities. The FCA itself is not applicable to this project because
    Buford was designed to be a multi-purpose project, and not merely a flood control project.
    Furthermore, it was not inconsistent for Congress to request contribution for projects that had to
    be altered to accommodate water supply, but not to request contribution for projects which
    merely replaced water supply already provided by the river, which water supply could be
    provided by the project as a by-product of power generation and with little detriment to other
    project purposes.
    26
    It bears noting that the Corps was not required to conduct cost-benefit analyses on
    all project purposes until 1952. See Bureau of Budget, Executive Office of the President, Budget
    Circular A-47 (Dec. 31, 1952).
    64
    One final point merits mentioning. Before the Dam was built, or even
    planned, the Chattahoochee provided almost all of the City of Atlanta’s water
    supply. The building of the dam could have been a potential threat to the city’s
    ability to withdraw water from the river because the Corps had an
    incentive—optimal power generation—to shut off all water flow in the river for
    long stretches of time. Congress responded to this concern by establishing a
    minimum flow requirement and noting that this requirement might have to be
    increased over time. Congress also clearly indicated that the Buford Project was
    intended to benefit the Atlanta area’s needs by assuring the water supply. If water
    supply had been deemed a subordinate purpose by Congress, the Buford Project
    would have been detrimental, rather than beneficial, to the Atlanta area’s water
    supply needs. That is to say, if the only water being supplied was to be a
    subordinate byproduct of power generation, then the City of Atlanta would have
    eventually found itself able to withdraw less water from the river than it would have
    been had no dam been built at all. In light of the repeated references in the
    authorizing legislation to safeguarding and ensuring an adequate water supply for
    Atlanta, Congress very clearly did not intend the dam to harm the city’s water
    supply.
    The language of the RHA clearly indicates that water supply was an
    65
    authorized purpose of the Buford Project. Appellees’ arguments to the contrary are
    unconvincing for all of the reasons mentioned above. Thus, we conclude that water
    supply was an authorized purpose of the RHA and that the RHA authorized the
    Corps to allocate storage in Lake Lanier for water supply.
    Part III.    Georgia’s 2000 Request Must Be Remanded to the Corps
    The Corps argues that its interpretation of the RHA in the 2002 Stockdale
    Memo, which supplied the legal reasoning for the denial of Georgia’s water supply
    request, is entitled to deference from this Court. The RHA authorized the Corps to
    build the Buford Project in accordance with the Corps’ plans and “with such
    changes therein as in the discretion of the Secretary of War and the Chief of
    Engineers may be advisable.” H.R. Doc. No. 80-300, Letter from Lieutenant
    General R.A. Wheeler, Chief of Engineers ¶ 16. The Corps asserts that this gives the
    agency wide latitude in its interpretive authority. Additionally, the Corps argues that
    because it prepared the reports which comprise the language of the RHA, its
    “interpretation of the statute merits greater than normal weight because it was the
    [Corps] that drafted the legislation and steered it through Congress with little
    debate.” Howe v. Smith, 
    452 U.S. 473
    , 485, 
    101 S. Ct. 2468
    , 2476 (1981). Despite
    the high level of respect owed to the Corps’ interpretations with regard to the RHA
    66
    due to its unique role in shaping the statute, we cannot defer to the Corp’s
    interpretation of its water supply authorization in this instance. Even heightened
    deference cannot lead this Court to ignore the plain and express will of Congress,
    especially where, as here, the Corps’ interpretation has not been consistent.
    Under the APA, reviewing courts must set aside agency action that is
    “arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with
    law.” 5 U.S.C. § 706(2)(A). The denial of Georgia’s request was based on a clear
    error of law—the Corps’ misinterpretation of the RHA. Therefore, the Corps’
    interpretation cannot be granted deference, in spite of the agency’s role in drafting
    the language of the legislation.
    The seminal case Chevron, U.S.A., Inc. v. Natural Resources Defense
    Council, Inc., 
    467 U.S. 837
    , 842–44, 
    104 S. Ct. 2778
    , 2781–82 (1984), set up a two-
    step framework for evaluating whether a court must defer to an agency’s
    construction of a statute it is charged with administering. Deference from the court
    is due if (1) Congress has not spoken directly on the precise question at issue and its
    intent is unclear, and (2) the agency’s interpretation is based on a permissible
    construction of the statute. 
    Id. The argument
    for Chevron deference in this case fails
    at both steps because Congress made clear its intention that water supply was an
    authorized purpose of the Buford Project. As discussed above, the Newman Report
    67
    repeatedly stated that the Buford project would protect and assure the water supply
    of the Atlanta metropolitan area. Furthermore, the Report authorized the use of
    water for water supply at the expense of maximum hydropower generation.
    Congress’ acknowledgment that water supply, in certain instances, was to be
    provided at the expense of maximum power generation necessitates the conclusion
    that water supply was not to be subordinate to other project purposes and was
    instead an authorized purpose in its own right. The Corps’ interpretation that the
    RHA relegated water supply to incidental status cannot be reconciled with the plain
    language of the statute. The clear Congressional intent in the 1946 RHA was that
    water supply was to be an authorized purpose, and the Corps’ contrary interpretation
    is erroneous and cannot be accepted by this Court.27
    A significant fact undermining any deference to the Corps on this issue is the
    fact that the Corps has also been inconsistent in its statements about whether water
    27
    The Corps concedes that the 2002 Stockdale Memo might not be entitled to
    Chevron deference because it may be deemed an internal guidance document that does not decide
    legal rights. See Christensen v. Harris Cnty., 
    529 U.S. 576
    , 587, 
    120 S. Ct. 1655
    , 1662–63
    (2000). If this is the case, then the Corps’ legal interpretations in the document deserve Skidmore
    deference, meaning that the interpretations are “entitled to respect . . . but only to the extent that
    those interpretations have the power to persuade.” 
    Id. (internal quotation
    marks and citations
    omitted). Because the clear intent of the RHA forecloses the higher Chevron level of deference, it
    follows that Skidmore deference is also not applicable to the facts of this case. In light of
    Congress’ intent to include water supply as an authorized purpose, the Corps’ contrary
    determination is not at all persuasive. Since neither type of deference can be given to the Corps’
    legal determinations, we need not decide whether the Skidmore or Chevron framework is
    applicable on the instant facts.
    68
    supply was an authorized purpose. The 2002 Stockdale Memo concluded
    (incorrectly) that water supply was not an authorized purpose, but this is not
    consistent with previous Corps statements on the matter. In the Corps’ 1949
    Definite Project Report, the Corps referred to water supply as one of the “primary
    purposes” and one of “the princip[al] purposes of the Buford Project.” ¶¶ 48, 115.
    This 1949 Report was a formal pronouncement on the issue, and the one most
    nearly contemporaneous to the actual enactment. In a 1987 regulation, 33 C.F.R. §
    222.5, App’x E, the Corps listed water supply as a project purpose for Buford. In the
    Corps’ comprehensive 1994 report to Congress, which listed the authorized
    purposes for Corps projects across the country, water supply was included as an
    authorized purpose of Buford under the RHA.28 U.S. Army Corps of Eng’rs:
    Hydrologic Engineering Center, Authorized and Operating Purposes of Corps of
    Engineers Reservoirs E-94 (1994). That report also defined the term “incidental
    benefits” and stated that incidental benefits, though they were important, were not
    the subject of the report and would not be listed. 
    Id. at 3–4.
    The Corps and the
    Appellees offer no explanation for why the Corps indicated that water supply was
    an authorized purpose in 1949, 1987, and 1994 but took a contrary position in
    28
    Recreation and fish and wildlife are also listed as authorized purposes in the
    report. However, the authorizing statute listed in the report for water supply is the RHA.
    Recreation and fish and wildlife are listed as being authorized by statutes not at issue in this case.
    69
    2002.29
    The Corps argues that even if it erred in its interpretation of the RHA, its
    rejection of Georgia’s water supply request should be allowed to stand. The Corps
    suggests that it accounted for the possibility that water supply was an authorized
    purpose of the Buford Project and still concluded that the request exceeded its
    authority. In support of this contention, the Corps points to the following language
    in the Stockdale Memo: “Even if water supply were a specifically authorized
    purpose of the reservoir (and the 1958 Act did not apply), the state’s request would
    require substantial changes in the relative sizes of project purposes. This would
    represent a material alteration of the project, which would require congressional
    action.” 2002 Stockdale Memo at 11 (internal quotation marks omitted).
    The Corps argues that this constitutes an alternative conclusion and that there
    is no reason to believe that it is incapable of considering a legal hypothetical. It
    29
    The Corps argues that any inconsistency in its interpretation is irrelevant to the
    deference analysis, citing National Cable & Telecommunications Ass’n v. Brand X Internet
    Services, 
    545 U.S. 967
    , 981, 
    125 S. Ct. 2688
    , 2699–2700 (2005). However, the holding of Brand
    X does not go quite this far. The case merely states that Chevron may be applicable to instances
    in which the agency has changed its position “if the agency adequately explains the reasons for a
    reversal of policy.” 
    Id. at 981,
    125 S. Ct. at 2699. This Court has also noted that an agency must
    be allowed to shift its position over time and that such shifts should even be accorded deference
    by reviewing courts. Friends of the Everglades v. S. Fla. Water Mgmt. Dist., 
    570 F.3d 1210
    ,
    1219 (11th Cir. 2009). But in this case, the Corps has given no explanation for the reasoning
    behind any changes in policy. Also, the Corps’ position has not merely changed; rather, it has
    been in such a constant state of flux that it appears to have not yet fully formed. In any event, the
    authorizing legislation itself is sufficiently clear; water supply is an authorized purpose.
    70
    argues that remanding the case for a consideration that it already gave would be
    duplicative. However, an administrative agency’s alternative explanation for
    denying a state’s request is “arbitrary, capricious . . . or otherwise not in accordance
    with law” if it is based on an impermissible reading of the authorizing statute or
    statutes. See Massachusetts v. Envtl. Prot. Agency, 
    549 U.S. 497
    , 532–34, 127 S.
    Ct. 1438, 1462–63 (2007) (holding that the EPA’s reading of a statutory phrase in
    its alternative explanation for why it did not regulate greenhouse gas emissions was
    not in conformity with the statute, and thus remanding to the EPA). The Corps’
    hypothetical, which is reiterated almost verbatim in the conclusion of the memo,
    2002 Stockdale Memo at 13, rests squarely on an erroneous legal proposition. In
    this alternative hypothetical, the Corps mistakenly assumes that the WSA would not
    apply to the agency’s determination of its authority to grant the Georgia request if
    water supply were authorized by the RHA. This assumption has no foundation in
    law. The WSA nowhere indicates that it is superceded by, or supercedes, original
    authorizations for water supply. The Act was merely intended to offer greater water
    supply authority in federal water projects than had previously existed. For that
    authority to be supplemental to authority already extant in a given project is
    perfectly consistent with the language and purpose of the statute. To assume, as the
    Corps has in its alternative conclusion, that the WSA does not apply to the Buford
    71
    Project merely because the authorizing statute included water supply as an
    authorized purpose is not supported by the language of the WSA or by its intended
    aim of increasing water supply authority in federal projects. The Corps’ holding in
    the alternative must be rejected because it misinterprets the scope of the WSA.
    The Corps’ alternative conclusion is also undermined because, despite the
    Corps’ contentions otherwise, its misinterpretation of the RHA was essential to its
    conclusion that it lacked authority to grant Georgia’s request. The majority of the
    memorandum is devoted to the potential effects of granting the request and whether
    these effects would be consistent with the Corps’ authority under the WSA. The
    discussion of the agency’s authority under the WSA is predicated on the assumption
    that the baseline level of authorization from the RHA is zero and that no storage
    may be allocated to water supply pursuant to the RHA. It is only at the very end of
    the discussion of the Corps’ authority that the agency considers arguendo the
    possibility that the RHA authorized water supply. Its brief discussion of this
    alternative is flawed in two respects. First, as noted above, the Corps erroneously
    assumes that if the RHA included water supply as an authorized purpose, the WSA
    would not be applicable at all. Second, although purporting to assume water supply
    was an authorized purpose of the RHA, the Corps nevertheless underestimated its
    RHA authority. It failed to recognize that the authorizing legislation in 1946 not
    72
    only included water supply as an authorized purpose but explicitly contemplated
    that the Corps was authorized to increase water supply usage over time as the
    Atlanta area grew and that this increase would not be a change from
    Congressionally contemplated operations at all. Thus, the Corps never considered
    its authority under the RHA to substantially increase its provision of water supply
    and reallocate storage therefor—authority which we hold today was granted by the
    RHA. And the Corps never considered its WSA authority to provide water supply as
    an addition to (or as supplementing) its RHA authority. The failure of the Corps in
    these respects renders its alternative reason for denying Georgia’s request arbitrary,
    capricious, or otherwise not in accordance with the law.30
    Several other factors also indicate that the Corps’ rejection of the water
    supply request should be remanded for further consideration. First, attached to the
    2002 Memo is a “preliminary analysis of the impacts of Georgia’s water supply
    request on authorized project purposes and operations.” The Corps’ analysis on the
    30
    For example, in the portion of the 2002 Stockdale Memo dealing with the
    alternative rationale, Stockdale 2002 at 11, the Corps spoke of the general limitation on its
    discretionary authority to make post-authorization changes in projects without seeking additional
    Congressional authority—i.e., the Corps’ lack of authority to make substantial changes in the
    relative sizes of project purposes—without any recognition of the fact that the authorizing
    legislation here already gave the Corps authority to increase the water supply purpose at the
    expense of the hydropower purpose and without recognition of the fact that the legislation
    explicitly contemplated a considerable such increase to meet the water supply needs estimated 19
    years in the future. See Newman Report ¶¶ 79, 80.
    73
    effects of the Georgia request was thus incomplete. Because the Corps’ authority to
    grant the request may be dependant on the precise size and effect of the request, it is
    crucial that the Corps complete its evaluation of the request. The need for further
    study recommends remand to the Corps.
    Second, it is also apparent that the Corps’ views regarding its authority to
    allocate storage in Lake Lanier to water supply are evolving and that it has not come
    to a final, determinative decision regarding the issues underlying this authority.
    There are several pieces of evidence for this. In 2002, the Corps rejected the
    Georgia request, asserting that it did not have sufficient authority to reallocate 34%
    of conservation storage. However, in 2004, it agreed to settle the Geren case, in part
    by reallocating what the settling parties determined at that time to be 22% of the
    conservation storage. The Corps determined that it could make such a reallocation
    on the basis of its WSA authority alone. Though these decisions are not directly
    conflicting, the Corps never explained why it believed that the 12% storage
    allocation difference between the two caused it to exceed its authority. If the RHA
    authorizes some storage reallocation to water supply, as we hold today that it does,
    then the Corps should explain why this difference in allocated storage between the
    Georgia request and the settlement agreement pushed it beyond the boundaries of its
    authority. Additionally, the Corps has revised its figures for how much storage must
    74
    be allocated to accommodate current levels of water supply withdrawal. In the 2002
    memo, the Corps asserted that current withdrawals required a 13% reallocation of
    conservation storage. On appeal, the Corps claims that the current withdrawal levels
    are only 11.7%. It appears that the Corps may no longer conclude that Georgia’s
    request would require an allocation as large as 34%. Any such decrease in the
    Corps’ projection of the amount of storage it deems required for water withdrawals
    could also affect its determination of its authority over the Georgia request.31
    31
    The Corps’ position in this appeal seems to favor evaluating water supply
    authority via an analysis of the detrimental effect of increased water supply on the production of
    hydropower as an alternative to an analysis predicated solely on the percentage of conservation
    storage being reallocated. See Brief of U.S. Army Corps of Eng’rs, et al. at 99–100, Tri-State
    Water Rights Litigation, No. 09-14657 (11th Cir. May 3, 2010) (explaining that the “de facto”
    reallocations of storage to account for current water supply uses causes a systemwide reduction
    of hydropower of only 1%). The present discussion of percentage allocations is not meant to be
    an endorsement of this method of evaluating the Corps’ authority. It is merely meant to describe
    the evolving nature of the Corps’ stated reasoning for its conclusions with respect to the bounds
    of its authority. In fact, the Corps’ former reliance on percentage-based allocations and its
    seeming current reliance on effects on project purposes may also represent a shift in policy. We
    conclude that the D.C. Circuit’s Geren opinion does not foreclose the Corps from fully exploring
    this issue. See infra, Part VI. On remand, the Corps should determine the optimal methodology
    for measuring its authority over water supply allocations.
    A companion consideration in the Corps’ WSA analysis is the concept of compensating
    the power users for the detrimental effects of water supply on the power purpose. The Corps
    accepted the notion of such compensation in the proposed settlement in Geren, though the record
    shows no preceding endorsement of this concept. Because the RHA authorized the
    accommodation of some water supply needs at the expense of the power purpose, the Corps must
    determine the proper balance between water supply and power. Consequently, the Corps must
    analyze whether compensation is a factor in determining the extent of the Corps’ authority under
    the RHA, whether under the WSA a reallocation of storage is an operational change, and whether
    such a change is major. See infra, Part VI, note 41, indicating that Geren’s comments on the
    compensation concept have no collateral estoppel effect.
    75
    Finally, because the other matters in this appeal must be remanded to the
    Corps, it is sensible and efficient for the agency to consider the overlapping issues
    that are common to Georgia and the other cases together as part of a comprehensive
    decision about the Corps’ future water supply operations. The conclusions that the
    Corps reaches with respect to the questions at issue in the other cases will provide it
    with a more complete analysis of the issues in Georgia, as well. For example, the
    Corps’ determinations of its authorization over current water supply withdrawals
    will necessitate a thorough study of the amount of storage required for water supply.
    Also, this appeal represents the first opportunity for a court to consider the Corps’
    authority under both the RHA and the WSA. Our holding—that water supply is an
    authorized purpose under the RHA, that the Corps does have some authority under
    the RHA to balance as among the authorized uses and increase the water supply
    purpose at the expense of the power purpose and to reallocate storage therefor, and
    that the Corps’ authority under the WSA is in addition to its authority under the
    RHA—constitutes a clarification of the legal environment which will aid the Corps
    in its analysis on remand. For these reasons, we conclude that the Corps must
    reexamine the request in light of its combined authority under the RHA and WSA.32
    32
    It should also be noted that the Corps was granted additional water supply
    authority in the 1956 Act. See infra, Part IV Section A. References in this opinion to the Corps’
    authority under the RHA and the WSA are not to be construed as negating its additional authority
    76
    Part IV.       Gwinnett County’s Claims Not Involving Authorization Under
    the RHA and WSA
    Gwinnett County asserts three claims that are distinct from the claims of the
    Georgia Parties and the Corps. First, the county asserts that a 1956 Act of Congress
    authorized the Corps to contract with it for 10 mgd for water supply. Second,
    Gwinnett asserts that the Corps contracted with it to provide permanent storage for
    roughly 40 mgd. Finally, the county asserts that the Buford Project rendered its
    intake facility at Duluth, Georgia inoperable and that it is therefore entitled to water
    withdrawal rights as just compensation. We find merit in the first of these claims but
    reject the final two.
    A. The Expiration of the 1956 Act
    In 1956, Congress passed an act, in part, stating the following:
    [T]he Secretary of the Army is hereby authorized to contract with
    Gwinnett County, Georgia, upon such terms and for such period not to
    exceed fifty years as he may deem reasonable for the use of storage space
    in the Buford Reservoir for the purpose of providing said county a
    regulated water supply in an amount not to exceed eleven thousand two
    hundred acre-feet of water annually . . . .
    Pub. L. No. 84-841, 70 Stat. 725. The district court noted in a footnote that
    Gwinnett had not contracted with the Corps pursuant to this authorization and held
    under the 1956 Act.
    77
    that the authorization “expired in 2006.” 
    Tri-State, 639 F. Supp. 2d at 1350
    n.24.
    The district court has misread the plain language of the statute. The fifty-year
    limitation in the Act refers to the duration of any contract with Gwinnett, not to the
    expiration of the Act itself. The phrase “not to exceed fifty years” immediately
    follows the words “contract . . . upon such terms and for such period” and there is
    no grammatical cue that it should not be read as modifying this phrase. The district
    court offers no explanation for its unnatural reading of the statute and none is
    evident to this Court. Moreover, the Act also authorized the Corps to enter into a
    perpetual easement with Gwinnett, authorizing Gwinnett to build the necessary
    facilities to withdraw water directly from Lake Lanier on the Corps’ land. 70 Stat. at
    725. It would be illogical for Congress to give Gwinnett a perpetual easement to
    implement an authorization that would expire in fifty years. The district court’s
    interpretation of the Act, which is espoused by Appellees in this appeal, is
    inconsistent with the Act’s language and its grant of an easement in perpetuity.
    To date there has not been a single contract between the Corps and Gwinnett
    predicated on the authority of the 1956 Act. Such a contract in the future would not
    be a reallocation of storage under the WSA or the RHA because it is directly
    authorized by Congress.
    B.    Forty mgd from the 1974 Supplemental Agreement to the Corps’
    78
    Contract
    Gwinnett argues that in 1974 the Corps granted the county the right to 38,100
    acre-feet of permanent storage so that it could withdraw roughly 40 mgd directly
    from Lake Lanier. In 1973, Gwinnett and the Corps entered into an interim water
    contract for 40 mgd. The following year, the parties revised Article 9 of the contract
    to provide:
    Upon expiration of the period of contract . . . the User shall have the right
    to acquire from the Government . . . the right to utilize storage space in
    the project containing at least 38,100 acre feet (which is estimated to be
    adequate to yield approximately 40 MGD of water).
    Supplemental Agreement No.1 to Contract No. DACW01-9-73-624 Between United
    States and Gwinnett County, Georgia for Withdrawal of Water from Lake Sidney
    Lanier (Apr. 29, 1974). The contract stated that this revision was being made “in
    order to facilitate the sale of bonds to finance [Gwinnett’s] proposed water works
    facilities.” 
    Id. Subsequent supplemental
    agreements extended the life of the contract
    until it was finally allowed to expire in 1990.
    The contract gave Gwinnett the “right to acquire” the storage space at the
    time of the expiration of the contract. Thus, Gwinnett possessed an option (an offer)
    to purchase storage space at the time of the contract’s expiration, which the parties
    agree occurred in 1990. “If no time is prescribed for accepting an offer, it must be
    79
    done within a reasonable time.” Wilkins v. Butler, 
    369 S.E.2d 267
    , 268 (Ga. Ct.
    App. 1988) (quotation omitted); see Home Ins. Co. v. Swann, 
    128 S.E. 70
    , 72 (Ga.
    Ct. App. 1925); Restatement (Second) of Contracts § 41 (1981). Gwinnett has not
    demonstrated that it exercised its acceptance of the option in 1990 or at any time
    since then. More than twenty years have elapsed since the time that the option
    became available, and the right to accept the Corps’ offer to acquire the 38,100
    acre-feet of storage clearly has lapsed.33
    C. Just Compensation for Relocation of the Duluth Intake
    On appeal, Gwinnett argues that it should have been compensated because the
    creation of the Buford Project led to contamination of its intake structure at Duluth,
    which had to be abandoned in the early 1970s. Gwinnett failed to make this
    argument before the district court. We generally do not consider arguments raised
    for the first time on appeal and need not do so here. Peek-a-Boo Lounge of
    Bradenton, Inc. v. Manatee Cnty., 
    630 F.3d 1346
    , 1358 (11th Cir. 2011).
    In any event, this argument is meritless. Gwinnett fails to discuss the rights of
    the federal government to make alterations to navigable waters. The federal
    33
    Gwinnett argues that any challenges to its right to storage under the 1974
    supplement are barred by the six-year statute of limitations for actions against the United States.
    28 U.S.C. § 2401(a). Though the statute has been extended to suits under the APA, it is clearly
    inapplicable here. Appellees, and/or the Corps, have nothing to challenge here, and consequently
    nothing that they are barred from challenging, because the Corps merely granted Gwinnett an
    unexercised option. No permanent storage rights were ever conferred on Gwinnett by the Corps.
    80
    government possesses what is known as a navigational servitude, “the privilege to
    appropriate without compensation which attaches to the exercise of the power of the
    government to control and regulate navigable waters in the interest of commerce.”
    United States v. Va. Elec. & Power Co., 
    365 U.S. 624
    , 627, 
    81 S. Ct. 784
    , 787–88
    (1961) (internal quotation marks omitted). The navigational servitude is a dominant
    servitude, trumping all competing and conflicting rights to the waterway. 
    Id. This servitude
    extends to the entire river and the riverbed lying below the high-water
    mark. United States v. Rands, 
    389 U.S. 121
    , 123, 
    88 S. Ct. 265
    , 267 (1967). It is
    anchored in Congress’ commerce clause power. “The power to regulate commerce
    comprehends the control for that purpose, and to the extent necessary, of all the
    navigable waters of the United States. For this purpose they are public property of
    the nation, and subject to all the requisite legislation by Congress.” 
    Id. at 122–23,
    88 S. Ct. at 266–67 (alteration omitted) (internal quotation marks omitted).
    The federal government does not execute a taking of riparian interests by
    altering rivers for navigational purposes. The government’s dominant right to make
    use of these waterways means that its actions do not amount to an appropriation.
    This premise has been explicitly stated several times in the context of hydropower
    interests: The federal government is not required to give compensation for water
    power when it takes riparian lands in accordance with the navigational servitude.
    81
    E.g., Va. 
    Elec., 365 U.S. at 629
    , 81 S. Ct. at 788; United States v. Twin City Power
    Co., 
    350 U.S. 222
    , 226–27, 
    76 S. Ct. 259
    , 262 (1956); United States v. Appalachian
    Elec. Power Co., 
    311 U.S. 377
    , 424, 
    61 S. Ct. 291
    , 307 (1940); United States v.
    Chandler-Dunbar Water Power Co., 
    229 U.S. 53
    , 73–74, 
    33 S. Ct. 667
    , 676 (1913).
    Gwinnett offers no explanation for why this principle should not be applied to the
    riparian interest in water supply.
    Because of the federal government’s dominant right to make alterations in the
    river, the effect on Gwinnett’s riparian interests is not a taking. Thus, even if
    Gwinnett had not abandoned its claim, the claim would not be compensable.
    Part V. Remand Instructions to the Corps
    On remand, the Corps is to reconsider Georgia’s request, as well as its
    authority with respect to the current provisions for water supply, in light of its
    authority under the RHA as well as the WSA and the 1956 Act. In particular, it
    should consider several important factors with respect to the Newman Report (i.e.,
    the RHA). First, the Corps should take into consideration that water supply for the
    Atlanta metropolitan area was an authorized purpose of the Buford Project as well
    as hydroelectric power, flood control, and navigation. Second, Congress
    contemplated that the Corps would be authorized to calibrate operations to balance
    82
    between the water supply use and the power use. Third, because Congress explicitly
    provided that the “estimated present needs” of the Atlanta area for water supply be
    satisfied at the expense of “maximum power value,” Newman Report ¶ 80, we know
    that the water supply use is not subordinate to the power use. Fourth, from
    Paragraphs 79 and 80 of the Newman Report, we know that Congress contemplated
    that water supply may have to be increased over time as the Atlanta area grows.
    However, the authorizing legislation is ambiguous with respect to the extent
    of the Corps’ balancing authority—i.e., the extent of the Corps’ authority under the
    RHA to provide water supply for the Atlanta area. On the one hand, the authorizing
    legislation recognized that the Chattahoochee River was the source of the water
    supply for the Atlanta area, and the legislation repeatedly referred to safeguarding or
    assuring the water supply of the metropolitan area. See Newman Report ¶¶ 79 and
    80. It also recognized that the minimum releases initially provided by the legislation
    to satisfy the present water needs “may have to be increased somewhat as the area
    develops.” 
    Id. ¶ 80.
    On the other hand, the legislation also contemplates that
    assuring such water supply for the Atlanta area can be done with a “slight decrease
    in system power value.” Id.34 We conclude that the Corps, the agency authorized by
    34
    Adding to the possible ambiguity, the quoted phrase from Paragraph 80 refers to a
    “slight decrease in system power value,” but Congress contemplated, in the preceding Paragraph
    79, a considerable increase in the river flow at Atlanta during off-peak hours in order to provide
    83
    Congress to implement and enforce this legislation, should, in the first instance,
    evaluate precisely what this balance should be.35
    Once the Corps has determined the extent of its authority under the RHA, it
    should then determine its authority pursuant to the WSA. The authority under the
    WSA will be in addition to the Corps’ authority under the RHA and the 1956 Act.
    for Atlanta’s water supply needs nineteen years in the future. Paragraph 79 contemplated
    increasing the river flow at Atlanta from 650 cfs to 800 cfs.
    35
    The Georgia Parties specifically assert that the Corps has authority under the RHA
    to increase releases from the dam in order to provide water supply to downstream users, and to
    reallocate storage for this purpose, an assertion with which we agree today. However, The
    Georgia Parties do not specifically assert that, in addition to the foregoing authority, the RHA
    also gives the Corps authority to make direct withdrawals from Lake Lanier for water supply.
    Although the authorizing legislation recognized that the Chattahoochee River was the source of
    water supply for the Atlanta area, and although Congress specifically contemplated ensuring and
    safeguarding the area’s water supply, the only way that the RHA mentions for ensuring the water
    supply of the Atlanta area is by means of increasing releases from the dam for the purpose of
    downstream withdrawals. It also appears that the Corps’ position has been more consistent with
    respect to its lack of authority under the RHA to provide direct withdrawals than it has in other
    regards. See F. G. Turner, U.S. Army Corps of Eng’rs: Mobile Division, Report on Withdrawal
    of Domestic Water Supply from Buford Reservoir (1955) (stating that the Corps advised
    Gwinnett County that it did not have the authority at that time—i.e., before the 1958 WSA—to
    grant a request for direct withdrawals for water supply and recommending that Congress provide
    the Corps with the additional authority necessary to grant this request). Finally, because it is
    unclear at this point precisely how much of the Atlanta area’s water supply the Corps will
    determine on remand it can provide pursuant to its clear RHA authority to increase releases for
    downstream water supply, because the 1956 Act clearly gives the Corps authority for a specific
    amount of direct withdrawals for Gwinnett County, and because the WSA clearly provides the
    Corps authority for direct withdrawals from the Lake (as long as the cumulative exercise of such
    Corps authority pursuant solely to the WSA does not constitute a “major operational change” or
    “seriously affect the purposes for which the project was authorized”), it is not clear that the issue
    of RHA authority for direct withdrawals is a live issue in this case. For all of the foregoing
    reasons, we express no opinion on whether the RHA could be construed to provide authorization
    for the Corps to satisfy the authorized water supply purpose, not only by increasing releases for
    downstream withdrawal but also by direct withdrawals from the reservoir.
    84
    It is apparent from the record and the evolving position of the Corps that the
    Corps has not arrived at a final, definitive determination of the scope of its authority
    to allocate storage to water supply. For example, it is not clear whether the Corps
    has arrived at a firm calculation of how many gallons per day can be provided for
    the Atlanta area’s water supply needs as a mere incident to, or byproduct of, power
    generation. The Corps’ latest figure, developed in 1986, in this regard has been 327
    mgd; however, at oral argument the Corps asserted that the calculation was not
    definitive and deserved more study. Also, it is apparent that the Corps has not
    arrived at a definitive, final determination of whether, and to what extent, storage
    reallocation would be necessary for RHA-authorized releases from the dam
    primarily for water supply purposes (and how to factor in the fact that these releases
    will still generate some power, though not of peak value). It is also unclear whether
    the Corps has arrived at a final determination of the appropriate measure for
    determining under the RHA what the impact of increased water supply use on power
    is, or the appropriate measure for determining under the WSA what constitutes a
    “major operational change.”36 Finally, the Corps has not yet articulated a policy on
    36
    In this regard, for example, the Corps should consider whether, and to what
    extent, considerations such as the following are relevant: percentage reallocation of conservation
    and/or other storage, measurements of decreases in systemwide power, and compensation to
    power customers. See also supra, note 31.
    85
    whether to account for return flows, and if so, how to differentiate between flows
    returned directly to the lake and flows returned downstream from the dam. These
    are some of the questions that the Corps should answer on remand, although we
    make no attempt to be exhaustive in that regard.
    As part of the final, definitive statement of the Corps’ water supply analysis,
    if the agency ultimately concludes that it does not have the authority to grant the
    Georgia request, it nevertheless should indicate the scope of the authority it thinks it
    does have, under the RHA, the WSA, and the 1956 Act. This way, the parties will
    have some further instruction, based on sophisticated analysis, of what the Corps
    believes to be the limitations on its power.
    Part VI.      Collateral Esoppel Effects on Remand Instructions
    To assist the Corps in making these determinations on remand, we address
    here whether certain statements from this Court’s decision in Alabama or the D.C.
    Circuit’s decision in Geren carry the force of collateral estoppel. Specifically, we
    discuss whether either of the two claims found to have preclusive force by the
    district court in the instant case is binding on the Corps and whether any of
    Alabama and Florida’s additional collateral estoppel arguments have merit. At the
    outset, we note that collateral estoppel applies only if (1) the issue at stake is
    86
    identical to the one involved in the prior proceeding; (2) the issue was actually
    litigated in the prior proceeding; (3) the determination of the issue was critical and
    necessary to the earlier judgment; and (4) the party against whom collateral estoppel
    is asserted had a full and fair opportunity to litigate the issue in the prior
    proceeding. Christo v. Padgett, 
    223 F.3d 1324
    , 1339 (11th Cir. 2000).
    The district court found collateral estoppel, preclusive effect in the D.C.
    Circuit’s conclusion that the WSA applied to interim reallocations of storage. Tri-
    
    State, 639 F. Supp. 2d at 1343
    . We take no issue with this application of collateral
    estoppel. On remand, the Corps will determine the extent of its authority to supply
    the current water supply needs of the Atlanta area, combining its authority under the
    1956 Act, the RHA, and the WSA. The Corps’ authority under the WSA (as well as
    the statutory limits thereto) are applicable to the Corps’ determination of its
    authority to supply current water supply needs, whether by force of collateral
    estoppel or clear statutory meaning or both.
    The district court also found preclusive effect in the D.C. Circuit’s holding
    that the reallocation of 22% of Lake Lanier’s conservation storage is a major
    operational change on its face. 
    Id. Several aspects
    of this holding merit discussion.
    First, and foremost, the Geren court considered only the Corps’ authority under the
    87
    WSA, not its authority under the RHA.37 Accordingly, a different issue is presented
    here. At the very least, this difference means that any water the Corps finds it is
    authorized to supply pursuant to the RHA is separate from the water it is authorized
    to supply pursuant to the WSA, and that this RHA-authorized water supply would
    not count against the Geren court’s 22% limit.38
    It is also possible that our reading of the authority provided by the RHA
    fundamentally changes the WSA analysis, given that the RHA congressionally
    authorizes the Corps to increase water supply in its balancing of hydropower and
    water supply needs, meaning that such reallocations to water supply arguably do not
    actually constitute a “change” of operations at all, and that the issue is therefore
    entirely different than the one presented to the Geren court. In other words, it is
    possible that the 22% holding has no preclusive force at all. However, because it is
    not clear that the Geren court’s 22% limit will be reached in this case,39 we
    37
    The settling parties—the Corps, SeFPC, and the Georgia Parties—did not make
    an issue of the Corps’ authority under the RHA because they were not in full agreement on
    whether water supply was an authorized purpose of the Buford Project. As settling parties
    defending a settlement, they had no incentive to assert issues about which they disagreed.
    38
    Of course, the authority granted under the 1956 Act for Gwinnett County also
    would not count against the Geren court’s 22% limit. Likewise, the parties and the courts have
    consistently assumed, and so do we, that the 10 mgd in compensatory withdrawals by Buford and
    Gainesville do not affect the amount of water that the Corps is authorized to supply under the
    various statutory grants.
    39
    There are two reasons the 22% limit may not be reached. First, the Corps has yet
    to determine the extent of its authority to allocate water to water supply under the RHA. The 22%
    88
    expressly decline to address the collateral estoppel effect of the Geren court’s 22%
    limit.40
    Second, it is clear that the question of whether percent reallocation of storage
    is the correct or sole measure of operational change was not actually litigated.
    Examination of the parties’ briefs in Geren makes clear that the parties assumed, but
    did not put at issue, the question of whether percent reallocation of storage is the
    correct or sole measure of operational change. Similarly, because the parties merely
    assumed that percent reallocation was the appropriate measure, the Geren court
    made the same assumption in its opinion, without any discussion of the issue. When
    an issue is merely assumed, it does not meet the actual litigation requirement for
    limit would not be reached unless the water allocated under the WSA represented at least a 22%
    reallocation above whatever allocation is authorized under the RHA. Second, as discussed in the
    two paragraphs immediately following this paragraph, percent reallocation of conservation
    storage may not be the correct or sole measure of operational change.
    40
    We do, however, expressly address the collateral estoppel effect of Geren’s
    alternative holding—that even a 9% increase in storage for water supply is a major operational
    change. The district court did not find preclusive effect to this holding. Alabama and Florida do
    not argue in their briefs that this holding is entitled to collateral estoppel, and Alabama and
    Florida expressly abandoned any such claim at oral argument. Nonetheless, we consider this
    issue in order to provide complete remand instructions to the Corps. Because the issue arose in
    Geren for the first time at oral argument, the Corps and the Georgia Parties had no opportunity to
    brief the issue. This alternative, and secondary, holding therefore wholly fails the “actually
    litigated” requirement for collateral estoppel. See Chi. Truck Drivers, Helpers & Warehouse
    Union (Independent) Pension Fund v. Century Motor Freight, Inc., 
    125 F.3d 526
    , 530 (7th Cir.
    1997) (expressing doubt that the issue of a regulation’s validity was actually litigated when it
    emerged only at the reply brief stage and received little discussion in the opinion,
    notwithstanding the fact that the party against whom collateral estoppel was asserted had raised
    the application of the regulation in its earlier response to summary judgment).
    89
    collateral estoppel. See Fields v. Apfel, 
    234 F.3d 379
    , 383 (8th Cir. 2000) (finding
    no issue preclusion with respect to whether a particular method for calculating
    disability benefits applied, because its applicability had merely been assumed by the
    court and both parties in a prior case and not placed at issue). The fact that the
    Geren court ruled “without thoroughly examining” the issue further undermines the
    preclusive effect of the ruling. A.J. Taft Coal Co. v. Connors, 
    829 F.2d 1577
    , 1581
    (11th Cir. 1987) (declining to apply collateral estoppel where the issue was not fully
    litigated, which resulted in the prior court tendering a conclusion “without
    thoroughly examining” the issue). Moreover, in this case, the district court did not
    hold that percent reallocation of storage is, as a matter of collateral estoppel, the
    correct or sole measure, and Appellees do not argue on appeal that we are bound by
    collateral estoppel to hold that percent reallocation of storage is the only appropriate
    measure of operational change. We conclude, for the foregoing reasons, that
    collateral estoppel does not bar the Corps from determining the appropriate measure
    of operational change on the basis of its own expertise. The Corps is free to consider
    on remand whether other measures, such as impact on hydropower,41 should be
    41
    It may be that the percent impact on hydropower is significantly less than the
    percent of storage reallocated to water supply under a given allocation scheme. For example, the
    Corps’ brief at 99–100 explained that the “de facto” reallocations of storage to account for
    current uses causes a systemwide reduction of hydropower of only 1%.
    Another aspect of the evaluation of detriment to hydropower is whether compensation to
    90
    considered instead of or in addition to percent reallocation of storage.
    Third, examination of the briefs in Geren also shows that the parties merely
    assumed that conservation storage was the appropriate frame of reference against
    which percent reallocation should be calculated, and the court likewise made this
    assumption. Accordingly, the actual litigation requirement is not met and the Corps
    is free to consider on remand whether some other portion of the dam’s capacity
    should also be considered. For instance, it may be that the flood control storage,
    which sometimes contains excess water that could be released to satisfy water
    supply needs, should be factored into the calculation.
    power users can be considered to mitigate any detriment. Although the Geren court rejected the
    idea that compensation to hydropower users might be relevant under the WSA, see 
    Geren, 514 F.3d at 1324
    , Alabama and Florida do not argue that this rejection gives rise to collateral
    estoppel. We consider the issue nonetheless in order to provide complete remand instructions to
    the Corps. For the following reasons, we conclude that collateral estoppel does not preclude the
    Corps from considering compensation to power users as a mitigating factor in its analysis of
    detriment to hydropower, if the Corps finds it appropriate to consider compensation for this
    purpose based on the exercise of its expertise. The concept of compensating power customers
    presents a different issue than the one considered in Geren because the D.C. Circuit failed to
    recognize the Corps’ authority under the RHA. As we hold today, the RHA authorizes the Corps
    to increase water supply at the expense of hydropower, and it contemplates that, in balancing the
    water supply and hydropower interests, the Corps should consider the magnitude of the detriment
    to hydropower. Because the Geren court failed to recognize this authority, it treated the proposed
    change in storage, and flow through, as a major operational change without considering the
    magnitude of the effect on hydropower and without considering whether financial compensation
    is relevant to that inquiry. Accordingly, the Geren court did not face the same issue with respect
    to the effect of compensation on the Corps’ authority as this Court. Because the issue is different,
    collateral estoppel does not apply. See 
    Christo, 223 F.3d at 1339
    . The Corps on remand may
    therefore make a fresh determination regarding whether financial compensation to power
    customers is material for the purpose of evaluating the magnitude of the detriment to
    hydropower.
    91
    Alabama and Florida advance two collateral estoppel arguments in addition to
    those already covered above. First, they argue that the Geren court decided that, for
    purposes of the WSA analysis, the baseline for storage against which major
    operational change should be measured is zero. They further argue that the decision
    has the effect of collateral estoppel. We disagree. As noted above, the Geren court
    expressly made no decision with respect to the Corps’ authority to allocate storage
    to water supply under the RHA.42 It addressed the issue of the appropriate baseline
    for the WSA analysis only in the context of rejecting the settling parties’ argument
    that the interim reallocation level prior to the settlement was the correct baseline. A
    wholly different issue is presented in this appeal, in which we are required to assess
    the Corps’ authority under the RHA to reallocate storage or otherwise provide water
    supply, and to factor this authority into the WSA analysis. Thus, the Geren court’s
    decision with respect to the baseline for storage reallocation has no collateral
    estoppel effect in this case.
    Second, Appellees argue that this Court’s earlier statement in Alabama, that
    water supply is not an authorized purpose of the Buford Project, is preclusive. As
    42
    Accordingly, Alabama and Florida are plainly wrong to the extent they argue that
    this aspect of Geren establishes collateral estoppel for purposes of finding that the RHA
    authorizes no storage for water supply. Likewise, Alabama and Florida are wrong to the extent
    that they argue that Geren establishes estoppel for the proposition that grants of authority under
    the RHA and WSA are not supplemental. Geren made no such holdings.
    92
    noted earlier in this opinion, this statement does not give rise to collateral estoppel
    because it was not actually litigated and it was mere dicta and therefore was not
    critical or necessary to the judgment. See supra, note 21. In conclusion, the Corps is
    not bound by collateral estoppel in making the aforementioned determinations and
    should make its decisions on remand on the basis of its own reasoned analysis.
    Part VII.     One-Year Time Limit on Remand
    This controversy has lasted a very long time. Since 1990, litigation related to
    this controversy has taken place in the Northern District of Alabama, the District
    Court for the District of Columbia, the Northern District of Georgia, the Northern
    District of Florida, the Middle District of Florida, the District of Columbia Circuit,
    and now five times in the Eleventh Circuit, and various attempts at compromise
    have been initiated and abandoned. Progress towards a determination of the Buford
    Dam’s future operations is of the utmost importance to the millions of power
    customers and water users that are affected by the operations of the project. The
    stakes are extremely high, and all parties are entitled to a prompt resolution.
    Accordingly, the process for arriving at a conclusion of the bounds of the Corps’
    authority should be as swift as possible without sacrificing thoroughness and
    thoughtfulness. Given the importance of this case, the length of time it has been
    93
    bouncing around the federal courts, and the amount of resources the parties and the
    courts have already expended, we believe that one year is sufficient for the Corps to
    complete its analysis of its water supply authority and release its conclusions. This
    panel will retain limited jurisdiction to monitor compliance with this time frame. At
    the end of this one-year period, we expect the Corps to have arrived at a well-
    reasoned, definitive, and final judgment as to its authority under the RHA and the
    WSA.
    CONCLUSION
    The Corps’ did not consummate its decision-making process in the Alabama,
    Apalachicola, and SeFPC cases. Therefore, the district court lacked jurisdiction to
    hear these claims. The Corps’ denial of Georgia’s 2000 water supply request did
    constitute final agency action, and the district court’s conclusion that it had
    jurisdiction to hear the Georgia case was proper. However, the court erred in its
    analysis of the Corps’ rejection of the request. The decisions of the District Court
    and the Corps were based on a clear error of law—the determination that water
    supply was not an authorized purpose of the RHA. Furthermore, the Corps failed to
    reach a final, determinative position about its water supply authority before
    rejecting the state’s request. Consequently, we reverse the district court’s order
    94
    granting the Corps summary judgment, and conclude that the Corps’ decision was
    arbitrary and capricious or not otherwise in accordance with the law. All four cases
    are remanded to the district court with instructions to remand to the Corps for
    reconsideration. This panel will retain limited jurisdiction to monitor the one-year
    time limit.
    Accordingly, the judgment of the district court is reversed, its findings of fact
    and conclusions of law in all four cases are vacated, and these cases are remanded to
    the district court with instructions to remand to the Corps for further proceedings
    not inconsistent with this opinion.
    REVERSED, VACATED, AND REMANDED; LIMITED
    JURISDICTION RETAINED.
