AMENDED OPINION
In this action the Yankton Sioux Tribe (Tribe) and its members sought declaratory and injunctive relief against officials of Charles Mix County

and the State of South Dakota

in respect to the boundaries of the Yankton Sioux Reservation. In an earlier stage of the case we held that the Tribe’s 1894 cession of certain land to the United States had diminished, rather than disestablished, the reservation and that some land retained reservation status.
Yankton Sioux Tribe v. Gaffey (Gaffey II),
An earlier action had been filed by the Tribe against the Southern Missouri Waste Management District (Waste District), seeking a declaration that the 1858 boundaries of the reservation remained intact and that therefore a particular site at issue was subject to federal environmental regulation. After the Tribe prevailed in the district court and on appeal,
Yankton Sioux Tribe v. S. Mo. Waste Mgmt. Dist.,
*998
On remand the original case w'as consolidated with this separate action against the county and state officials in which the Tribe seeks a declaratory judgment that all land not ceded to the United States in 1894 remains part of the Yankton Sioux Reservation under the jurisdiction of the Tribe and the federal government. The United States intervened on its own behalf and for the benefit of the Tribe. The district court ruled in favor of the Tribe, concluding that the reservation had not been disestablished but consisted of all land not ceded in 1894 as well as certain reserved “agency trust lands.”
Yankton Sioux Tribe v. Gaffey (Gaffey I),
Now' before our court are appeals filed by both sides from the judgment issued by the district court after additional proceedings on remand,
Yankton Sioux Tribe v. Podhradsky,
I.
The original boundaries of the Yankton Sioux Reservation were created by treaty between the Tribe and the United States on April 19, 1858, 11 Stat. 743 (1858 Treaty). In that treaty, the Tribe ceded more than 11,000,000 acres of land to the United States and reserved to itself approximately 430,400
4
acres in what is now Charles Mix County, South Dakota. The United States guaranteed to the Tribe “the quiet and peaceable possession of the said tract,”
In the first half of the nineteenth century, federal Indian policy focused on removing tribes from the eastern half of the *999 country and relocating them on western lands, but by the time of the 1858 Treaty, “federal policy had shifted fully from removal to concentration on fixed reservations.” Cohen’s Handbook of Federal Indian Law § 1.03[6][a], at 65 (2005 ed.) (Cohen ). These reservations were “envisioned as schools for civilization, in which Indians under the control of the agent would be groomed for assimilation.” Id.
As the westward migration of white settlers accelerated following the Civil War, pressure grew to open Indian reservations for agricultural and resource development by the newcomers. Supporters of Indian assimilation argued that as more Indians adopted white customs and agricultural practices, their need for large tracts of reservation land would diminish, freeing vast areas for white settlement and development. This approach was formalized in the General Allotment Act of 1887 (Dawes Act), ch. 119, 24 Stat. 388 (repealed in part by Pub.L. No. 106-462 § 106, 114 Stat. 1991, 2007 (2000)).
Under the Dawes Act, the executive branch was authorized to divide portions of Indian reservations into personally assigned allotments to be distributed to individual tribal members.
Id. §
1,
The allotment policy in general and the Dawes Act in particular were intended to hasten the demise of the reservation system and to encourage Indian assimilation into the white system of private property ownership. “Within a generation or two, it was thought, the tribes would dissolve, their reservations would disappear, and individual Indians would be absorbed into the larger community of white settlers.”
Yankton Sioux Tribe,
Acting under the authority of the Dawes Act, federal agents allocated to tribal members individual allotments comprising 167,325 acres of the then 430,405 acre Yankton Sioux Reservation. Another 95,-000 acres were subsequently allotted to tribal members under the Act of February 28, 1891, 26 Stat. 794 (1891 Act). These tribal allotments, totaling approximately 262,300 acres, were not contiguous parcels of land. Rather, the individual allotments were scattered across the reservation and interspersed with approximately 168,000 acres of unallotted surplus land. Commissioner’s Letter at 5.
In 1892 a three member Yankton Indian Commission, which represented the Secretary of the Interior, traveled to the reservation to discuss the federal government’s interest in acquiring the Tribe’s surplus land. After lengthy negotiations, the Tribe agreed to sell all of the unallotted acreage to the United States for $600,000. The ceded land was then to be opened to white settlement, with the exception of roughly 1,000 acres specifically reserved for use by the United States for “agency, schools, and other purposes.” Act of August 15, 1894, ch. 290, 28 Stat. 286, 316 (1894 Act). These set aside agency reserve lands were expected to be opened for white ownership at such time as they were no longer needed for the Tribe’s support.
Id.
The Supreme Court has com
*1000
mented that the set aside of these agency lands is evidence that Congress envisioned an ongoing reservation despite the sale of the surplus lands.
Yankton Sioux Tribe,
Congress ratified the cession agreement by statute in the 1894 Act, and in May 1895 President Grover Cleveland issued a proclamation opening the ceded land to white settlement, In
Yankton Sioux Tribe
the Supreme Court ruled that the land ceded to the United States under the 1894 Act was thus no longer part of the Yank-ton Sioux Reservation but fully subject to the jurisdiction of South Dakota.
Subsequently Congress passed the Act of May 8, 1906, ch. 2348, 34 Stat. 182 (Burke Act), amending § 6 of the Dawes Act. The Burke Act gave the Secretary of the Interior the discretion to remove allotted land from trust status and to issue fee simple patents, either upon the death of an Indian allottee or upon a finding that an allottee was “competent and capable of managing his or her affairs.”
In 1916, recognizing the rapid erosion of the Tribe’s allotted lands, President Woodrow Wilson issued an executive order extending by ten years the trust period on all but approximately 150 of the parcels still held in trust on the Yankton Sioux Reservation. Exec. Order No. 2363, Apr. 20, 1916. The trust periods were again extended in 1926 and 1929. Exec. Order No. 4406, Mar. 30, 1926; Exec. Order No. 5173, Aug. 9, 1929. In 1929 Congress also reconsidered the disposition of the roughly 1,000 acres of land which had been set aside for “agency, schools, or other purposes.” Although the 1894 Act originally envisioned that these lands would be opened to white settlement once they had served their intended purposes, Congress decided instead to return them to the Tribe and specifically precluded any allotments on these parcels. Act of February 13, 1929, ch. 183, 45 Stat. 1167 (1929 Act).
During this period, the consequences of the allotment and assimilation policies became acutely obvious. The process of allotment and the liberalized issuance of fee patents under the Burke Act left many Indians landless and reduced once coherent communities to jurisdictional checkerboards, as is currently reflected in respect to the Yankton Sioux Reservation. Cohen, § 1.04, at 78. Moreover, “[t]he process of *1001 transforming Indian culture into white culture proved more difficult than placing an Indian name on allotted land deeds.... [T]he cultural resilience of the American Indian amazed even the most dedicated reformer.” Id. at 80.
By the early twentieth century, the forces behind allotment and assimilation were nearly exhausted, and federal policy was reoriented towards “new protections for Indian rights, support for federally defined tribalism, and encouragement of historical and anthropological concerns such as arts, crafts, native rituals, tourism, and traditional economic systems.” Id. § 1.05, at 84. In time this new attitude led to the Indian Reorganization Act of 1934 (IRA), ch. 576, 48 Stat. 984 (codified as amended at 25 U.S.C. § 461 et seq.).
The IRA reflected a fundamental change in federal Indian policy. It prohibited further allotment of Indian lands and indefinitely extended the trust periods for outstanding allotments. The Act also authorized the Secretary of the Interior to acquire additional lands in trust—-both on and off reservation—and either to proclaim these lands part of a new reservation or to add them to an existing one. Since the passage of the IRA, the government has taken almost 6,500 acres into trust for the benefit of the Yankton Sioux Tribe.
This tangled history, along with the inconsistent and sometimes contradictory policies pursued by the national government, has produced a confusing patchwork of land holdings and jurisdictional claims within the original 1858 boundaries of the reservation. For ease of exposition, we have identified six general categories of land.
(1)Allotted Trust Lands: lands allotted to members of the Tribe which have been continuously held in trust for the benefit of the Tribe or its members. This category includes allotments which were later transferred from individual to tribal control, so long as the trust status was maintained. The district court found 30,051.66 acres of land fit this description. 6
(2) Agency Trust Lands: lands ceded to the United States in the 1894 Act but reserved for “agency, schools, and other purposes” which then were returned to the Tribe according to the 1929 Act. The district court identified 913.83 acres of land within this category. We held this category of land to be part of the diminished Yankton Sioux Reservation in Gaffey II.188 F.3d at 1030 .
(3) IRA Trust Lands: lands acquired by the United States in trust for the benefit of the Tribe pursuant to the IRA. The district court identified 6,444.47 acres of such land.
(4) Miscellaneous Trust Lands: lands acquired by the United States in trust for the benefit of the Tribe other than pursuant to the IRA. Approximately 174.57 acres fit within this category.
(5) Indian Fee Lands: allotted lands later transferred in fee to individual Indians and which have never passed out of Indian ownership. The record does not identify lands which may fit this description.
(6) Non Indian Fee Lands: lands ceded to the United States in the 1894 Act and subsequently opened to white settlement which have not been reacquired in trust; and noneeded lands originally allotted to tribal members but later transferred in fee to non Indians and never reacquired in trust.
*1002 Of these six categories, the first four may be generically referred to as “trust lands” and the last two as “fee lands.”
The trust lands are spread across the site of the original 1858 reservation in a complex checkerboard pattern, inter-mingled with lands long since occupied by white homesteaders. As a result the Yankton Sioux trust lands are not neatly contained within a single continuous boundary. The defendants urge that this characteristic shows the reservation has ceased to exist, but they cite no authority wiiieh requires that a reservation consist of compact, contiguous lands. While the fractured configuration of the Yankton Sioux Reservation may not seem ideal to various parties, it is a historic artifact resulting from shifting federal policy. There was evidence at trial that the parties have long experience in dealing with this historical reality. For example, defendant Scott Podhradsky, state’s attorney for Charles Mix County, testified that local and federal officials have developed a respectful and productive working relationship despite the complex jurisdictional boundaries.
In short, the 11,000,000 acre domain once assigned to the Tribe was successively fragmented and dramatically reduced in size: first to roughly 430,400 acres in 1858 and then to 262,300 acres in 1894. The issues now before us include the status of some 37,600 acres held in trust. Whatever the size of the remaining reservation lands, there is evidence in the record that they have continuing relevance and importance to the Yankton Sioux Tribe as a touchstone linking tribal members with each other and with their common culture, history, and heritage.
II.
In September 1994 the Yankton Sioux Tribe commenced its civil action against the Waste District seeking to prove that the site of a proposed landfill was in fact located on the Yankton Sioux Reservation and was therefore subject to federal environmental regulations. The Waste District filed a third party complaint and added the State of South Dakota as a party. In 1995 the district court decided that the original reservation boundaries as established by the 1858 Treaty remained in force.
Yankton Sioux Tribe v. S. Mo. Waste Mgmt.
Dist.,
The Supreme Court reversed, holding that all lands which had been ceded to the United States pursuant to the 1894 Act had thereby lost reservation status and were returned to the public domain. The Court specifically reserved the question of whether the 1894 Act had disestablished the entire reservation or whether a diminished reservation continued to exist within the nonceded lands.
South Dakota v. Yankton Sioux Tribe,
On remand the district court consolidated the original case against the Waste District with this separate civil action brought by the Tribe against various state and county officials seeking injunctive and declaratory relief. The Tribe asserted that the Yankton Sioux Reservation had been diminished only by those lands ceded in the 1894 Act and that all other lands within the 1858 boundaries—that is, the 262,300 acres comprising the original allotted trust lands—-remained part of the reservation regardless of their later disposi
*1003
tion. The Tribe argued that such lands were therefore -within the jurisdiction of the Tribe and the federal government. The United States successfully intervened on behalf of the Tribe. After considering the parties’ arguments, the district court held in favor of the Tribe and the government and declared that the Yankton Sioux Reservation continued to exist and consisted of the agency trust lands in addition to all other lands which had not been ceded in the 1894 Act.
Yankton Sioux Tribe v. Gaffey (Gaffey I),
The defendants appealed, and this court affirmed in part, reversed in part, and remanded.
Yankton Sioux Tribe v. Gaffey (Gaffey II),
In sum, in
Gaffey II
we held that the Yankton Sioux Reservation had not been disestablished but diminished, and that it consisted of at least the agency trust lands but did
not
include lands which had passed into white ownership. We remanded to the district court with instructions to develop the record and make findings relevant to the status of the remaining categories of land. All parties petitioned for en banc review, which was denied.
Yankton Sioux Tribe v. Gaffey,
No. 98-3894 (8th Cir. Dec. 8, 1999) (order denying petition for rehearing with petition for rehearing en banc). The Supreme Court denied certiorari.
Yankton Sioux Tribe v. Gaffey,
On remand the parties conducted additional discovery, after which the district court conducted a two day trial and considered a voluminous set of historical documents and government reports, along with numerous spreadsheets and area maps relevant to the various land holdings in dispute. The district court then made findings of fact and conclusions of law, settling all the contested issues about reservation status in favor of the Tribe. The district court began by recognizing our Gaffey II holding, including that the agency trust lands which had been returned to the Tribe were part of a diminished Yankton Sioux Reservation. The district court then determined that all outstanding allotments which had maintained their trust status— whether for the benefit of the Tribe in common or for individual members—continued to be part of the reservation. Next, the district court held that all lands taken into trust pursuant to the IRA were reservation land; the district court determined alternatively that this category of trust lands is at a minimum “de facto” reservation or a “dependent Indian community” subject to federal and tribal jurisdiction. Finally, the district court ruled that for *1004 mer allotments which were now owned in fee by tribal members were part of the reservation so long as such lands had never passed out of Indian ownership.
The district court also made several ancillary rulings. In particular, it held that, notwithstanding the Tribe’s contrary assertion, a 1927 congressional enactment had not frozen the boundaries of the reservation. It further held that the 1934 IRA had frozen the boundaries, but that a subsequent 1948 measure ended that freeze. The district court also rejected a claim by the defendants that 3,201 acres of land allegedly taken into trust by the United States for the benefit of the Tribe were never formally accepted into trust status and therefore cannot be considered trust lands or reservation. The district court held that such a challenge to the trust status of the lands was barred by the United States’ sovereign immunity and that such immunity had not been waived by the Quiet Title Act, 28 U.S.C. § 2409a.
The district court’s final judgment decreed that the agency trust lands, outstanding allotments, IRA trust lands, and Indian owned fee lands continuously held in Indian hands qualified as reservation. It denied all other claims asserted by the parties. The final judgment did not incorporate the district court’s alternative holdings, and it is from that judgment that appellants and cross appellants have taken their appeals.
On their appeal, the defendants challenge the district court’s conclusions that the various trust lands are part of the Yankton Sioux Reservation, either formally or informally, or that such lands support a dependent Indian community. They also persist in asking us to reconsider
Gaffey II
and continue to argue, contrary to that decision, that the reservation has been completely disestablished and that even the agency trust lands lack reservation status. Finally, they contend that the district court erred in not considering their claim that the United States had failed formally to accept certain lands into trust. On its cross appeal, the Tribe objects to the district court ruling that the reservation boundaries are not frozen. The United States asks us to affirm the district court decision in its entirety. We review the findings of fact made by the district court in a bench trial for clear error and review de novo its legal conclusions and mixed questions of law and fact.
Eckert v. Titan Tire Corp.,
III.
Before we turn to review of the district court’s findings and conclusions on remand, we must take up several preliminary issues raised there and argued again on appeal. First among these is the defendants’ continuing challenge to our holding in Gaffey II that the Yankton Sioux Reservation had not been disestablished.
Gaffey II
squarely held that the Yank-ton Sioux Reservation was never disestablished and that, although diminished, the reservation continues to exist and at a minimum consists of the agency trust lands reserved to the United States for “agency, schools, and other purposes” and later returned to the Tribe. These holdings were part of the law of the case remanded to the district court. The law of the case doctrine means “that when a court decides upon a rule of law, that decision should continue to govern the same issues in subsequent stages in the same case.”
Gander Mountain Co. v. Cabela’s, Inc.,
We observed in
Gaffey 11
that the 1894 Act reserved the agency trust lands to the federal government Cor the purpose of pro
*1005
viding “aid and education to tribal members so long as they were needed.”
Gaffey II,
Under the law of the case doctrine, “a decision in a prior appeal is followed in later proceedings unless a party introduces substantially different evidence, or the pri- or decision is clearly erroneous and works a manifest injustice.”
United States v. Bartsh,
The defendants’ new evidence introduced at the coux't trial on remand does not undermine our analysis in Gaffey II. They rely principally on testimony by a former official of the Bureau of Indian Affairs and an agent of the Federal Bureau of Investigation, both of whom said that they personally would exercise jurisdiction over agency trust land only so long as it was held in trust. Because these witnesses based their jurisdiction on the land’s trust status as opposed to any reservation status, the defendants argue their testimony undermines the concept of a continuing reservation. According to the trial transcript, these witnesses were never asked whether the agency trust land also qualifies as reservation land, and it is far from clear that their statements reflect a considered jurisdictional distinction between reservation land and various trust properties. More importantly, their testimony sheds little light on the intentions of either the nineteenth century parties who negotiated the agreement between the Tribe and the federal government or of the Secretary' of the Interior in making decisions to add trust land to an existing reservation. The defendants also point to evidence that the agency trust lands are located on two distinct parcels and are not contiguous, which is not surprising given the checkerboard nature of the allotments.
It is not clear that any of the defendants’ evidence was truly “new” in the sense that it could not have reasonably been developed and presented in earlier stages of this litigation. As another court pointed out in rejecting an attempt to challenge the law of the case with newly presented evidence, “[tjhere is nothing in the record to indicate that the evidence produced at the hearing after remand was unavailable to the [litigants] during the first trial. [They] simply chose not to produce that evidence. They chose their trial strategy, litigated accordingly, and lost.”
Baumer v. United States,
Most significantly, the rulings in
Gaffey II
have not been shown to be erroneous. They were based on an exhaustive analysis of the historical materials surrounding the Tribe’s agreement with the federal government and the 1894 ratification of that agreement, as well as the subsequent history.
Gaffey II,
The defendants also argue that two parcels of the agency trust land, totaling 106 acres, were not within the scope of the 1929 Act which returned the balance of the agency trust lands to the Tribe. These two parcels were conveyed by fee patents to the Chapter of Calvary Cathedral Episcopal Church in 1897 and in 1920. They were thus owned by that church when Congress directed in 1929 that the agency trust lands be returned to the Tribe, rather than be opened for white settlement once they were no longer needed for their intended purposes. The defendants argue that because these 106 acres were in private hands at the time of the 1929 Act, they were not within the Act’s purview and are thus outside of
Gaffey II’s
holding that agency trust land “reserved to the federal government ... and then returned to the Tribe continues to be a reservation.”
IV.
We now turn to the jurisdictional questions at the heart of this case. Reservation land is by definition “Indian country,” and as a general rule Indian country falls under the primary civil, criminal, and regulatory jurisdiction of the federal government and the resident Tribe rather than the states.
See Alaska v. Native Village of Venetie Tribal Gov’t,
[T]he term “Indian country” ... means (a) all land within the limits of any Indian reservation under the jurisdiction of the United States Government, notwithstanding the issuance of any patent, and, including rights-of-way running through the reservation, (b) all dependent Indian communities within the borders of the United States whether within the original or subsequently acquired territory thereof, and whether within or without the limits of a state, and (c) all *1007 Indian allotments, the Indian titles to which have not been extinguished, including rights-of-way running through the same.
Prior to the enactment of § 1151, the evolving concept of Indian country had mainly been developed and refined by the courts in their attempts to stay abreast of changing conditions in the American West and in federal Indian policy. See Cohen, § 3.04[2][b], at 184-88.
Congress reentered the debate in 1948 by adopting § 1151, Act of June 25, 1948, ch. 645, 62 Stat. 683, 757, but the statute mainly codified earlier Supreme Court decisions regarding Indian country. The language in § 1151(b) is taken almost verbatim from the Court’s conclusion in
United States v. Sandoval,
Section 1151(a) confirms that reservations are properly considered Indian country and are therefore under the primary jurisdiction of the federal government and the relevant tribes. In this sense it is in accord with such cases as
Bates v. Clark,
Section 1151(a) thus separates the concept of jurisdiction from the concept of ownership. In doing so Congress sought both to resolve inconsistencies in prior case law,
see
18 U.S.C. § 1151 Historical and Revision Notes, and to maintain jurisdictional continuity where reservation lands had been patented in fee,
see Seymour v. Superintendent of Wash. State Penitentiary,
A.
Having ruled in Gaffey II that the Yank-ton Sioux Reservation had not been disestablished, we remanded for the district court to consider, among other matters, the status of allotted trust lands wfeich had retained their trust status. All sides to this litigation acknowledge, as they must, that such lands qualify at the very least as Indian country under § 1151(c), which explicitly identifies allotments as such. The disputed issue is whether these allotments are also part of the Yankton Sioux Reservation and therefore also qualify as Indian country' under § 1151(a).
The distinction is important since lands which qualify only under § 1151(c) would *1008 lose then- Indian country status if their governing trusts were ever terminated or revoked. If these lands also quality as reservation, however, their Indian country status would be considerably more durable. Under § 1151(a) reservation lands retain their status “notwithstanding the issuance of any patent,” including a patent which terminated a trust and conveyed the land in fee simple. After considering the evidence at trial, the district court held that the allotments were indeed part of an ongoing reservation and qualified as Indian country under § 1151(a).
The Supreme Court held in
So-lent
that “[ojnce a block of land is set aside for an Indian reservation ... the entire block retains its reservation status until Congress explicitly indicates otherwise.”
Prior to the expiration of the trust period, the allotted lands “remained Indian lands set apart for Indians under governmental care; and we are unable to find ground for the conclusion that they became other than Indian country through the distribution into separate holdings, the Government retaining control.”
Pelican,
It is clear from the circumstances surrounding the Tribe’s agreement to sell its surplus lands that the Tribe did not intend to relinquish immediate jurisdiction over the allotments and that it would not be required to part with them. In the discussions leading up to the agreement, a government negotiator explained to tribal members that
[the Great White Father] wants to give you a chance to sell your surplus lands.... He has told us to tell you that you will not be farced to part with your lands unless you, ■want to.... He does not leant you to sell your homes that he has allotted to you. He wants you to keep your homes forever.
Council of the Yankton Indians (Oct. 8, 1892),
transcribed in
S. Exec. Doc. 27, 53d Cong., 2d Sess., 47, 49 (1894) (emphasis added). These reassurances acquire particular significance in light of the longstanding rule that an agreement between the United States and an Indian tribe
*1009
should be “construed, not according to the technical meaning of its words to learned lawyers, but in the sense in which they would naturally be understood by the Indians.”
Washington v. Wash. State Commercial Passenger Fishing Vessel Ass’n,
In their report on the outcome of their negotiations with the Tribe, the federal commissioners wrote that “the purchase of the surplus lands was but a small part of our mission and of minor importance to both the Indians and the Government, the provisions connected therewith for the future welfare of the Indians being of greater importance.... ” Report of the Yankton Indian Commission (Mar. 31,1893), reprinted, in S. Exec. Doc. No. 27, 53d Cong., 2d Sess., 7, 17 (1894). In particular, the Tribe was anxious to insure that annuity payments from the federal government would continue uninterrupted. The historical evidence thus reveals that the Tribe, while willing to sell its surplus, was concerned with maintaining a presence on the allotted lands and preserving the support of the federal government and its superintendence over those lands.
The final agreement, as ratified in the 1894 Act, reflects this understanding. As already noted, the Act set aside the agency trust land specifically to support the Tribe, a provision which the Supreme Court found “counsels against finding the reservation terminated.”
Yankton Sioux Tribe,
Simply stated, there is nothing in the historical and documentary record to indicate a congressional intent to terminate the reservation status of the allotted lands immediately upon ratification of the 1894 Act or the opening of the ceded territory to white settlement. In the absence of such an intention, we must conclude that at the time of the Act those lands retained the same reservation status they had enjoyed since the original 1858 Treaty. Even if Congress had foreseen an eventual end to the reservation, one which would perhaps be hastened by the allotment policy,
9
such an expectation would not have been at odds to the nineteenth century mind with the ongoing maintenance of a reservation on the allotted lands. The fact that tribal members maintained beneficial property interests in the allotments is further evidence that the reservation status of those lands was preserved since at the time Indian land ownership was linked with reservation status. See,
e.g., Solem,
In the course of setting out the twists and turns in the federal policy regarding tribal lands,
Gaffey II
recounted Congress’s original expectation that allotments would lose their reservation status as they passed out of Indian ownership and into white hands.
It is irrelevant for present purposes what the 1894 Congress expected to happen to allotments after they lost trust status, for the allotments at issue in this case have been continuously held in trust. The determinative question is simply whether they are now “reservation” within the meaning of § 1151(a). Having found no congressional intent in the 1894 Act to divest these lands of their reservation status, we can only conclude that they remain reservation to this day, for “when Congress has once established a reservation, all tracts included within it remain a part of the reservation until separated therefrom by Congress.”
Celestine,
Any alleged inconsistency between our holding in Gqffey II and the district court’s determination in this case that allotments are reservation land under § 1151(a) is nothing of the sort. It merely reflects the evolution of federal Indian policy and the defendants’ anachronistic attempt to force a nineteenth century agreement into the mold of current legal principles. 10 The district court did not err when it concluded that all outstanding allotted lands continue to be reservation and qualify as Indian country under § 1151(a).
B.
On remand the district court was also asked to consider the status of lands taken into trust by the federal government pursuant to the Indian Reorganization Act. The district court concluded that when lands which were once part of the original 1858 reservation wrere taken into trust under the IRA, they reacquired reservation status. It identified 6,444.47 acres of such land and classified them as Indian country under § 1151(a). The defendants appeal this holding while the Tribe and the United States support it. 11
Congress passed the IRA in 1934, authorizing the Secretary of the Interior “to acquire ... any interest in lands ...
*1011
within or without existing reservations ... for the purpose of providing land for Indians.” IRA § 5, 25 U.S.C. § 465. The purpose of the Act was to further the independence of tribes and strengthen their ability to govern themselves.
See Cohen,
§ 1.05, at 86 (The IRA was meant “to encourage economic development, self-determination, cultural pluralism, and the revival of tribalism.”). Its provisions are meant “to stabilize the tribal land base,”
Nichols v. Rysavy,
The defendants argue that taking land into trust for the benefit of an Indian tribe is insufficient to convert such land into Indian country, but their position runs contrary to well settled precedent. As the Supreme Court has recognized, “[s]ection 465 provides the proper avenue for [a tribe] to reestablish sovereign authority over territory.... ”
City of Sherrill v. Oneida Indian Nation of N.Y.,
The Tribe and the United States assert that wThen former reservation land is reacquired in trust under the IRA it is not just Indian country, but a particular type of Indian country, namely reservation within the meaning of § 1151(a). The difference is important because Indian country under § 1151(a) has the distinct property of retaining its status “notwithstanding the issuance of any patent.” In other words, such land remains part of the reservation even if sold. The defendants argue, however, that the Yankton IRA trust lands do not qualify as reservation under § 1151(a) because the Secretary of the Interior has not issued a formal proclamation to that effect. They rely on § 7 of the IRA, 25 U.S.C. § 467, wrhich provides that the Secretary “is ... authorized to proclaim new Indian reservations on lands acquired ... or to add such lands to existing reservations” (emphasis added).
While there is no doubt that § 467 requires a proclamation when the Secretary wishes to establish a new reservation, the statute does not state that a proclamation is required when the Secretary decides to add land to a preexisting reservation such as that of the Yankton
*1012
Sioux. Congress left the decision to the Secretary, authorizing the Secretary “to proclaim new Indian reservations ... or to add such lands to existing reservations.”
Id,
(emphasis added). The statutory language does not itself require a proclamation in the case of preexisting reservations, and the “cardinal canon” of statutory interpretation is “that a legislature says in a statute what it means and means in a statute what it says there.”
Conn. Nat’l Bank v. Germain,
When § 467 was drafted in 1934, the concept of Indian country lacked the benefit of § 1151’s precise definition. Fine distinctions between reservation land, trust land, allotted land, dependent Indian communities, and the like would have carried little practical weight since jurisdiction was at the time essentially synonymous with Indian ownership. It would therefore have made sense for the congressional drafters of § 467 to provide for the Secretary to distinguish by means of a proclamation between acquisitions of land intended to create a new reservation and acquisitions of land simply to be held in trust. Land held in trust by the federal government for addition to an existing Indian reservation would have been perceived as under federal jurisdiction even without a proclamation.
The IRA “was designed to improve the economic status of Indians by ending the alienation of tribal land and facilitating tribes’ acquisition of additional acreage and repurchase of former tribal domains.” Cohen, § 1.05, at 86 (emphasis added). Indeed, a principle motivation for the IRA was to “permit progress toward the consolidation of badly checkerboarded Indian reservations.” 78 Cong. Rec. 11,730 (1934) (statement of Rep. Howard). In keeping with that legislative intent, the Secretary made the decision to reacquire land in trust which had been formerly recognized as part of an existing reservation, the Yankton Sioux Reservation. This is entirely different from acquisition of land never previously recognized as under Indian jurisdiction. When the Secretary proclaims an intent to reincorporate trust land as a new reservation, it serves to give notice to all of a significant change in condition.
The parties most directly affected by a trust acquisition—the United States as trustee and the Tribe as beneficiary— both agree that the Secretary’s decision to take former Yankton Sioux Reservation land into trust was sufficient to restore that land to its previous reservation status. The Secretary has preeminence in interpreting laws under the Department’s jurisdiction,
Tang v. INS,
The regulations reflect that the acquisition of former' reservation land is likely to pose fewer problems than an acquisition of land which has no historical connection to a tribe’s land base. Current regulations treat trust acquisitions of former reserva *1013 tion lands as “on reservation” rather than “off reservation” transactions, see 25 C.F.R, § 151.2(f) (defining reservation to include “that area of land constituting the former reservation”), and subject them to less searching scrutiny. For example, if a tribe requests an off reservation acquisition—that is, one involving land which is not nor ever has been part of a reservation—the regulations require the Secretary to consider “[t]he location of the land relative to state boundaries, and its distance from the boundaries of the tribe’s reservation.” 25 C.F.R. § 151.11(b). If off reservation land is being acquired for business purposes, “the tribe shall provide a plan which specifies the anticipated economic benefits.” Id. § 151.11(c). Such regulations are consistent with our own analysis that restoration through the IRA of territory historically part of the Yank-ton Sioux Reservation is distinguishable from the acquisition of lands never within Indian domain and may be accomplished without a proclamation.
Moreover, the defendants can cite no statutory language or case law making an official proclamation necessary before former reservation lands can reacquire their reservation status. The only case they point to involved the establishment of a new reservation, not the return of former reservation land to an existing one, and is thus inapposite.
See Citizens Exposing Truth about Casinos v. Kempthorne,
The defendants also argue that treating trust acquisitions of former reservation land differently from other acquisitions would grant significance to the 1858 boundaries despite the Supreme Court’s determination in Yankton Sioux Tribe, and our own conclusion in Gaffey II, that the original boundaries have been altered by the reservation’s diminishment. While it is true that the original 1858 boundaries are no longer markers dividing jurisdiction between the Tribe and the state, that does not mean to say they have lost their historical relevance for the Secretary’s discretionary acts. Defendants argue that the IRA’s legislative history, the Department of the Interior’s internal guidelines, and the Cohen handbook stand for the proposition that some official action beyond the acquisition of land is necessary when adding trust land to an existing reservation.
Here, the lands under consideration were part of this tribe’s 1858 reservation and have been reacquired in trust “for the purpose of providing land for Indians.” 25 U.S.C. § 465. We believe this presents a distinct question, one which the sources cited by the defendants simply do not resolve. There is a fundamental difference between acquiring land which has no historical connection to an existing reservation and reacquiring land which once formed part of a Tribe’s land base. While Congress has provided that an official proclamation by the Secretary is necessary for adding such unrelated land to a reservation, it has not required it for the latter. The district court did not err in its conclusion that all lands taken into trust by the Secretary under § 465 fall within the jurisdiction of the Yankton Sioux Reservation and qualify as Indian country under § 1151(a).
C.
Although the district court identified 174.57 acres of miscellaneous land acquired in trust other than under the IRA, it did not directly address the status of these miscellaneous lands. Its separate discussion of dependent Indian communities was broad enough to cover all trust properties, however, including the miscellaneous plots.
In
Venetie
the Supreme Court noted that it had not yet “had an occasion to interpret the term ‘dependent Indian communities’ ” as the term is used in
*1014
§ 1151(b).
The miscellaneous trust lands easily meet this definition. The lands were acquired for the use and benefit of the Yankton Sioux Tribe, and the district court found that the federal Bureau of Indian Affairs “negotiates the leases, collects the rents and distributes the rents according to tribal status reports” with respect to these lands.
Gaffey I,
The defendants argue that the federal government’s administration of these lands in trust is insufficient to meet the Supreme Court’s definition of dependent Indian communities as it was announced and applied in
Venetie.
That case involved lands held under the Alaska Native Claims Settlement Act (ANCSA), Pub.L. No. 92-203, 85 Stat. 688 (codified as amended at 43 U.S.C. § 1601
et ¡seq.).
ANCSA was specifically “intended to avoid a ‘lengthy wardship or trusteeship.’ ”
Venetie,
Consequently, we conclude that the miscellaneous trust lands at issue in this case qualify as dependent Indian communities and are Indian country under § 1151(b).
D.
The Tribe and the United States also urge us to uphold the district court’s determination that former allotments which have been continuously held in fee by Indian owners constitute reservation land. The defendants seek reversal. 13
Although we might assume that such lands exist, the record does not identify any or their relevant histories. We therefore conclude that this issue is not ripe for resolution. “The ripeness doctrine flows both from the Article III ‘cases’ and ‘controversies’ limitations and also from prudential considerations for refusing to exercise jurisdiction.”
Neb. Pub. Power
*1015
Dist. v. MidAmerican Energy Co.,
Here, a number of potentially important facts are missing with respect to Indian owned fee lands continuously held by tribal members. To start, no one has identified which, if any parcels, fit within this category. Moreover, the status of such lands may depend on a number of unknown factors, including whether the allotments expired at the natural end of the trust period, whether the fee patents were issued at the request of allottees, or whether the fee patents were “forced” on allottees pursuant to the Burke Act. After deciding that this category of land remained reservation, the district court noted that many of these historical facts could be developed by consulting “the land title records maintained by the BIA’s Realty Office.”
Podhradsky,

The Tribe further asserts that two Congressional enactments—-the Act of March 3, 1927, § 4, ch. 299, 44 Stat. 1347 (codified as amended at 25 U.S.C. § 398d) (1927 Act), and the 1934 IRA—froze the boundaries of the reservation. Consequently, it argues, any lands alienated in fee to whites during the effective period of any such freeze should be considered part of the reservation. The district court determined, however, that the 1927 Act does not apply to the Yankton Sioux Reservation and that whatever freeze the IRA may have imposed was lifted by the Supervised Sales Act, ch. 293, 62 Stat. 236 (1948) (codified at 25 U.S.C. § 483) (Sales Act). The United States and the defendants ask us to uphold the district court rulings on these issues.
With respect to the 1927 Act, the Tribe maintains that the statute prohibited alterations to the boundaries of any Indian reservation except by act of Congress. The defendants respond that the plain terms of the 1927 Act limit its application to reservations created by executive action rather than by treaty. The district court agreed with the defendants and concluded that the statute was inapplicable in the current dispute.
By the mid nineteenth century, Presidents “had begun to withdraw public lands from sale by executive order for the specific purpose of establishing Indian reservations.”
Sioux Tribe of Indians v. United States,
The language of the 1927 Act does indeed limit its application to executive order reservations: Hjereafter changes in the boundaries of reservations created by
Executive
order, proclamation, or otherwise for the use and occupation of Indians shall not be made except by Act of Congress ....”
The Tribe also argues that the 1934 IRA froze the reservation’s boundaries. Section 2 of that act indefinitely extended the trust period for all outstanding allotments, 48 Stat, at 984 (codified at 25 U.S.C. § 462), while § 4 states that “[e]x-cept as herein provided, no sale, devise, gift, exchange or other transfer of restricted Indian lands ... shall be made or approved ....”
Id.
at 985 (codified as amended at 25 U.S.C. § 464). The district court concluded that these provisions effectively froze any further diminishment of the Yankton Sioux Reservation, but it also concluded that the Supervised Sales Act, ch. 293, 62 Stat. 236 (1948) (codified at 25 U.S.C. § 483) (Sales Act), lifted whatever freeze was imposed.
See Oglala Sioux Tribe of Pine Ridge Indian Reservation v. Hallett,
We have never squarely confronted the effect of the IRA on the Secretary’s authority under the Burke Act to issue fee patents to “competent” allottees, thereby removing trust restrictions on the alienation and conveyance of Indian lands. However, in Oglala Sioux Tribe, we assumed without deciding that the IRA had effectively frozen the Secretary’s ability to issue fee patents. Id. at 330. In the same case, we also determined that the Sales Act had lifted any such freeze. Id. at 330-31.
The Tribe argues that allotments on the Yankton Sioux Reservation were unaffected by the Sales Act since they had been granted under the Dawres Act and the 1891 Act, not under the IRA. While it is true that by its terms the Sales Act applies to allotments “held ... under” the IRA, 25 U.S.C. § 483, we concluded in
Oglala Sioux Tribe
that by extending indefinitely the trust periods of previously awarded allotments, the IRA brought within its protection even allotments awarded prior to its enactment.
The Tribe argues that even if the Sales Act did undo an IRA imposed freeze, land conveyances in fee to whites during the effective period of the freeze were improper and should be disregarded for the purpose of defining the reservation’s current boundaries. The Tribe’s arguments suffer from an insufficient factual record, however. As the district court noted with respect to the Tribe’s 1934 freeze claim, “no proper foundation was established for the admission of ... evidence” indicating that any land would have been affected by such a freeze.
Gaffey I,
V.
In the absence of any clear congressional intent to divest allotted lands on the Yankton Sioux Reservation of their reservation status, those lands retained such status, and all outstanding allotments continue to be reservation under § 1151(a). Furthermore, lands originally part of the Tribe’s 1858 reservation regained their status as reservation land under § 1151(a) when acquired in trust under the Indian Reorganization Act. The miscellaneous trust lands, by contrast, qualify as part of a dependent Indian community and are therefore Indian country under § 1151(b). Finally, the record regarding fee lands continuously held by tribal members is not ripe for review.
With respect to the judgment of the district court, we therefore:
(1) affirm insofar as it concluded that the agency trust lands, the outstanding allotments, and the IRA trust lands are part of the Yankton Sioux Reservation and are Indian country under § 1151(a),
(2) affirm its alternative holding that the miscellaneous trust lands constitute a dependent Indian community and are Indian country under § 1151(b),
(3) vacate the district court’s holding that fee lands continuously held in Indian ownership are reservation under § 1151(a), and
(4) affirm its denial of all other claims for relief.

. The Tribe has never dismissed its action against the Waste District which remains an inactive interested party, not having filed a notice of appeal. The district court observed that district representatives were present during the Podhradsky trial but had not played an active role after October 2004.
. Although the 1858 Treaty refers to 400,000 acres, a later survey concluded the reservation contained 430,405 acres at the time of the treaty. See Letter from the Commissioner of Indian Affairs to the Secretary of the Interior (Dec. 9, 1893), reprinted in S. Exec. Doc. No. 27, 53d Cong., 2d Sess., 1, 5 (1894) (Commissioner's Letter).
. The Tribe argues that the Burke Act did not apply to allotments made on the Yankton Sioux Reservation and that therefore some 300 "forced fee patents" issued under it should be considered null and void. The Tribe did not raise this argument until after the case was before the district court for the third time. As that court noted, "[tjhere is ... a limit as to what should be undertaken ... to determine reservation boundary issues that were not raised or addressed by this Court nor the superior courts. This issue ... [is| beyond the scope of this litigation....”

No. CIV 98-4042,

Yankton Sioux Tribe
the Supreme Court mentioned 30,000 acres held in trust for individual Indians and 6,000 acres of "tribal lands.”
. The defendants rely on
Bruguier

Class,
. Section 1151 was originally enacted to define criminal jurisdiction, but its definition of Indian country is widely recognized to apply to civil matters as well.
See Venetie,
. It is worth noting that the eventual expiration of the allotments was never a foregone conclusion. The Dawes Act allowed the president to extend the allotment period, which Presidents Wilson, Coolidge, and Hoover each did. The allotments were then indefinitely extended under the 1934 Indian Reorganization Act.
. As already discussed, the origins of the checkerboard pattern of the Yankton Sioux Reservation lie in the federal government's former allotment policies and its liberal issuance of fee patents under the Burke Act.
. The defendants also claim that the United States failed formally to approve some 29 deeds conveying land in trust. These deeds affect approximately half of the IRA trust lands. The defendants argue that since the deeds were recorded without a formal acceptance by the government, the lands conveyed by them are not validly held in trust and cannot qualify as Indian country under any portion of § 1151. As the district court observed, “this case involves jurisdiction issues and does not affect title to real estate.”
Podhradsky,
. The defendants point to dictum in
United States v. Stands,
. The defendants maintain that our mandate in
Gaffey ¡I
limited the district court to an analysis of trust lands. This is incorrect, for we noted that the record then before us was insufficient to address the issue of fee lands continuously held in Indian ownership,
