ARTICLE II
DEFINITIONS

For purposes of this Compact, and for no other purposes, the following definitions apply:

(1) "Acre-foot" means the amount of water necessary to cover one acre to a depth of one foot and is equivalent to 43,560 cubic feet.

(2) "Annual" or "per year" means the calendar year commencing January 1 and ending December 31.

(3) "Board" means the Fort Peck-Montana Compact Board established by Article VI.

(4) "Conservation (carry-over) storage" is storage provided in a reservoir to capture and hold water that would otherwise go downstream. Such storage holds the water for beneficial use later in the season or is carried over to a subsequent season or seasons. Evaporation from the surface of such reservoir is considered to be a consumptive use to the extent that it exceeds the evaporative and transpirational losses which occurred in the reservoir area prior to its construction.

(5) "Consumptive use" means the amount of irrigation water that is transpired by vegetation, converted in the processes of photosynthesis and plant tissue growth, and evaporated from adjacent soils, water surfaces and foliage. For uses other than irrigation, consumptive use means the quantity of water diverted less the quantity of reusable return flow within the State.

(6) "Court of competent jurisdiction" means a state or federal district court which otherwise has jurisdiction of the subject matter and the parties, or a tribal court which otherwise has such jurisdiction provided that all parties to the case consent to tribal court jurisdiction.

(7) "Diversion" means the removal of water from its natural course or location by means of a ditch, canal, flume, bypass, pipeline, conduit, well, pump, or other structure or device, or the impoundment of water in a reservoir. Where a reservoir is constructed or operated on a stream, the annual diversion shall be the greater of:

(a) the inflow into the reservoir minus the outflow for releases or spills downstream from the reservoir, or

(b) withdrawals of water from the reservoir for actual use.

(8) "Domestic use" means the diversion of water by one or more individuals, family units or households for drinking, cooking, laundering, sanitation and other personal comforts and necessities; and for the irrigation of a family garden or orchard not exceeding one-half acre in area.

(9) "Fort Peck Irrigation Project" means those irrigation systems and works constructed pursuant to the Act of May 30, 1908, 35 Stat. 558, and all lands receiving water from such systems and works.

(10) "Fort Peck Reservoir" means that body of surface water impounded by Fort Peck Dam, at the current spillway elevation.

(11) "Full service irrigation" means any form of irrigation that distributes water on a regularly scheduled basis in order to satisfy the full seasonal crop and soil water requirements.

(12) "Ground water" means any water located under the surface of the land or the bed of any stream, lake, reservoir, or other body of surface water. All other water shall be considered surface water.

(13) "Indian" means any person who:

(a) is an enrolled member of the Tribes; or

(b) is a member of a tribe that is recognized as eligible for the special programs and services provided by the United States to Indians because of their status as Indians; or

(c) holds or is recognized by the Secretary of the Interior as eligible to hold trust or restricted property on the Reservation.

(14) "Industrial" means the use of water for any uses that benefit an industrial enterprise including, but not limited to, industrial cooling, energy production, and evaporation associated with any industrial operation. Among the purposes excluded from the industrial use category are irrigation, stockwater, and domestic uses.

(15) "Instream flow" means that quantity of water scheduled to remain in a stream to maintain fish and wildlife resources.

(16) "Missouri River" means the river formed by the confluence of the Gallatin, Jefferson and Madison Rivers in southwestern Montana, and flowing easterly beyond the eastern boundary of Montana.

ARTICLE III
TRIBAL WATER RIGHT

A. General Statement of the Tribal Water Right. The Assiniboine and Sioux Tribes of the Fort Peck Indian Reservation have the right to divert annually from the Missouri River, certain of its tributaries, and ground water beneath the Reservation the lesser of (i) 1,050,472 acre-feet of water, or (ii) the quantity of water necessary to supply a consumptive use of 525,236 acre-feet per year for the uses and purposes set forth in this Compact with a priority date of May 1, 1888, provided that no more than 950,000 acre-feet of water, or the quantity of water necessary to supply a consumptive use of 475,000 acre-feet may be diverted annually from surface water sources. This right is held in trust by the United States for the benefit of the Tribes and is further defined and limited as set forth in this Compact.

B. Persons Who May Use the Tribal Water Right. All uses of water authorized under any applicable law by the following persons shall be considered and calculated as uses of the Tribal Water Right:

1. the Tribes within or outside the Reservation;

2. all individual Indians using water within the Reservation including, but not limited to, Indians exercising uses established pursuant to state law prior to the effective date of this Compact;

3. all non-Indian successors-in-interest to any allottee actually using water within the Reservation by virtue of a water right arising under the laws of the United States, which water right was acquired directly or indirectly from an Indian predecessor-in-interest;

4. all other persons receiving water from the Fort Peck Irrigation Project including, but not limited to, persons exercising uses established pursuant to state law prior to the effective date of this Compact;

5. all other persons authorized to use water by the Tribes pursuant to this Compact, within or outside the Reservation;

6. the United States as trustee for the Tribes or any Indian including, but not limited to, persons exercising uses established pursuant to state law prior to the effective date of this Compact.

C. Measure of Consumptive Use for Irrigation. Irrigation usage of the Tribal Water Right shall be conclusively deemed to cause a consumptive use of 1.8 acre-feet per acre per year for full service irrigation and 0.48 acre-feet per acre per year for partial service irrigation. Any loss of water due to evaporation from reservoirs constructed in the future for conservation (carry-over) storage rather than for regulatory storage by the United States for the benefit of the Tribes or any Indian, or constructed for such conservation storage by the Tribes or by any Indian, shall be counted as a consumptive use.

D. Purposes for Which the Tribal Water Right May be Used. Within the Reservation, use of water in the exercise of the Tribal Water Right for any purpose may be authorized by the Tribes without regard to whether such use is beneficial as defined by valid state law. No use of the Tribal Water Right may be wasteful or inconsistent with the terms of this Compact. Outside the Reservation, any use of water in the exercise of the Tribal Water Right shall be beneficial as defined by valid state law on the date the Tribes give notice to the State of a proposed use outside the Reservation.

E. Facilities Diverting or Using the Tribal Water Right Outside the Reservation. All persons diverting or using the Tribal Water Right outside the Reservation, including the Tribes as sovereign, shall apply for all permits, certificates, variances and other authorizations required by valid state laws regulating, conditioning or permitting the siting, construction, operation, alteration or use of any equipment, device, facility or associated facility proposed to use or transport water located outside the Reservation, and shall comply with all applicable provisions of this Compact. A diversion or use of water in the exercise of the Tribal Water Right may be made only after all permits, certificates, variances or other authorizations applied for pursuant to this paragraph have been obtained, and the diversion or use has not been found unlawful by a court of competent jurisdiction.

F. Amounts To Be Diverted from the Missouri River.

1. Diversions of water for use within or outside the Reservation may be made in the exercise of the Tribal Water Right from Fort Peck Reservoir and the mainstem of the Missouri River--but without utilization of the conservation (carry-over) storage of Fort Peck Reservoir--in the following amounts:

(a) during the months of November, December, January, February and March, not to exceed 40,000 acre-feet per month;

(b) during the months of April and October, not to exceed 50,000 acre-feet per month;

(c) during the months of May and September, not to exceed 105,000 acre-feet per month;

(d) during the month of June, not to exceed 145,000 acre-feet;

(e) during the month of July, not to exceed 215,000 acre-feet;

(f) during the month of August, not to exceed 180,000 acre-feet.

Provided that the aggregate of monthly diversions in the exercise of the Tribal Water Right from surface water shall not exceed 950,000 acre-feet per year, and the total annual consumptive use shall not exceed 475,000 acre-feet.

2. The Tribes shall report the amount of all actual diversions from Fort Peck Reservoir and the mainstem of the Missouri River to the United States Army Corps of Engineers by April 1st of the calendar year following the year in which such diversions are made in accordance with paragraph 5 of section J of this Article.

3. All diversions authorized by paragraph 1 of this section may be made without payment to the United States, but the Tribes and any user of the Tribal Water Right shall otherwise comply with all generally applicable laws and regulations of the United States.

G. Export of the Tribal Water Right Outside the State. Use of the Tribal Water Right outside the State shall be in compliance with all valid provisions of state law in effect at the time of the proposed transfer that prohibit, regulate, condition, or permit the transportation of water outside the State.

H. Non-use of the Tribal Water Right not a Forfeiture. Non-use of any part of the Tribal Water Right shall not constitute a relinquishment, forfeiture or abandonment of the right to such use.

I. Sources of Diversions of the Tribal Water Right. In the exercise of the Tribal Water Right water may be diverted:

1. Within the Reservation for use within the Reservation from:

(a) the mainstem of the Missouri River within or adjacent to the Reservation;

(c) by the State or by a person whose rights are adversely affected by the proposed diversion or use.

In any such case, the Tribes shall have the burden of going forward and the burden of proving by a preponderance of the evidence that they have satisfied the requirements of paragraph 1 of this section.

3. Diversions of water in the exercise of the Tribal Water Right outside the Reservation from the mainstem of the Missouri River above Fort Peck Reservoir, as authorized in subparagraph 3(d) of section I of this Article, may be made so long as the Tribes or any user of the Tribal Water Right:

(a) comply with all the laws of the State in effect at the time the diversion is proposed, including but not limited to state water use statutes;

(b) give not less than 180 days advance written notice of any proposed diversion in the manner required in paragraph 5 of this section:

(i) if the diversion is to be made from a reservoir, to the operator of the reservoir; or

(ii) if the diversion is not to be made from a reservoir, to the operator of the first dam, upstream and downstream, if any, from the point of diversion;

(c) obtain approval of the diversion from the State legislature.

4. For purposes of demonstrating compliance with subparagraph 1(c) and subparagraph 3(a) of this section and paragraph 6 of Section K of this Article, the portion of the Tribal Water Right to be diverted will be deemed an appropriative right which has:

(a) been acquired on May 1, 1888;

(b) a point of diversion and use where the water is actually being diverted and used or, if not actually being diverted, where the water would first flow on or adjacent to the Reservation;

(c) the existing use or, if not actually in use, an irrigation use provided, however, that the use can be transferred to a purpose other than irrigation without restriction as to period of use so long as the requirements of Section F of this Article are observed;

(d) the actual consumptive use or, if not actually in use or if being used for irrigation purposes, a consumptive use of 1.8 acre-feet per acre per year; and

(e) not been abandoned or forfeited.

(c) the amount proposed or authorized for annual consumptive use;

(d) the point of diversion;

(e) the period of use;

(f) the place of use; and

(g) the purposes for which the water may be used.

K. Transfers of the Tribal Water Right.

1. As an incident to and in the exercise of the Tribal Water Right, the Tribes may transfer within or outside the Reservation, as authorized by federal law and this Compact, the right to use water but may not permanently alienate such right or any part thereof. Any such transfer of water by the Tribes shall be subject to all provisions of this Compact.

2. Prior to making any transfer which authorizes use of water outside the Reservation to be diverted from the mainstem of the Missouri River, including Fort Peck Reservoir, the Tribes shall give not less than 180 days advance written notice to the State of the proposed terms and conditions of the transfer, and shall offer the State the opportunity to participate in the transfer as a substantially equal partner with the Tribes, assuming obligations and receiving benefits of the transfer under terms and conditions agreed to by the Parties. If the State does not accept the opportunity within the 180-day notice period, or if the State unreasonably delays the institution or completion of approval processes required by state law or unreasonably delays resolution of any litigation arising from its decision to accept the opportunity, the Tribes may proceed with the proposed transfer without State participation, provided that the proposed transfer shall be subject to all other provisions of this Compact. If the State does not accept the opportunity, or if State participation in the joint transfer is not approved, the State shall not later pursue the opportunity, except in accordance with all the terms of this Compact, including paragraph 3 of this section.

3. Prior to making any transfer allowing use or diversion of water from Fort Peck Reservoir or from the mainstem of the Missouri River below Fort Peck Dam, the State shall give not less than 180 days advance written notice to the Tribes of the proposed terms and conditions of the transfer and shall offer the Tribes the same opportunity to participate in the transfer as a substantially equal partner with the State, assuming obligations and receiving benefits of the transfer on terms and conditions agreed to by the Parties. If the Tribes do not accept the opportunity within the 180 day notice period, the State may proceed with the proposed transfer without the Tribes' participation, and the Tribes shall not later pursue the opportunity except in accordance with all the terms of this Compact, including paragraph 2 of this section.

4. If otherwise authorized by federal law, the Tribes may enter into an agreement with any person who is exercising or proposing to exercise a right under the laws of the State to use surface water outside the Reservation on any tributary of the Missouri River that flows through or adjacent to the Reservation, except the mainstem of the Milk River, which agreement allows such person's diversion and use and protects it from any other exercise of the Tribal Water Right provided, however, that:

(a) before use of such water, the person shall have complied with all applicable state laws concerning the acquisition of a water right;

(b) subsequent to acquisition of the state water right, regulation of its use shall be subject to state law;

(c) the amount of water subject to the agreement shall be considered a consumptive use of the Tribal Water Right;

(d) the agreement shall not permanently alienate the Tribal Water Right or any part thereof.

5. The Tribes may transfer annually only the following amounts of water for consumptive use outside the Reservation:

(a) 50,000 acre-feet;

(b) plus 35 percent of any amount over 200,000 acre-feet but less than 300,000 acre-feet authorized by state law to be transferred annually by the State from waters within the State;

(c) plus 50 percent of any amount over 300,000 acre-feet authorized by state law to be transferred annually by the State from waters within the State.

Transfers of the Tribal Water Right shall not be considered as part of any amounts authorized by state law to be transferred annually by the State.

6. In no event shall the Tribes be authorized to transfer less than 50,000 acre-feet of water per year outside the Reservation. The limits established in paragraph 5 of this section shall apply so long as the State is authorized to transfer annually at least 50,000 acre-feet of water pursuant to state law. If statutory authorization for the State to transfer water is not enacted, is repealed, or is held invalid, or if the amount of water authorized by state law to be transferred by the State is less than 50,000 acre-feet per year, then for any period in which the authorization or the limitation is not in force the Tribes may transfer water in accordance with all terms and conditions of this Compact other than paragraph 5 of this section. However, such transfers will be subject to any volume limitations provided by federal law or, in the absence of any federal volume limitations, the Tribes may transfer water in accordance with all terms and conditions in this Compact other than paragraph 5 of this section and with any volume limitations imposed by state law which would apply to a holder of a right to the use of water established pursuant to state law. For the purposes of complying with volume limitations imposed by state law, the Tribal Water Right will be deemed to have the characteristics set forth in paragraph 4 of section J of this Article.

7. Unless authorized by federal law, the State shall not in any manner whatsoever tax any proceeds received by the Tribes as consideration for any transfer of the Tribal Water Right.

L. Instream Flows.

1. At any time within five years after the effective date of this Compact, the Tribes may establish a schedule of instream flows to maintain any fish or wildlife resource in those portions of streams, excluding the mainstem of the Milk River, which are tributaries of the Missouri River that flow through or adjacent to the Reservation. These instream flows shall be a part of the Tribal Water Right with a priority date of May 1, 1888. Water remaining in a stream to maintain instream flows pursuant to such a schedule shall be counted by the Tribes as a consumptive use of surface water.

2. Instream flows may be established by the Tribes only in accordance with this section. The Tribes may change the use of water for maintenance of instream flows to another purpose only with the consent of the State.

M. No Other Diversion or Use of the Tribal Water Right. No other diversion or use of the Tribal Water Right shall be made other than those authorized or recognized by this Article.

ARTICLE VI
FORT PECK-MONTANA COMPACT BOARD

A. Board established. There is hereby established the Fort Peck-Montana Compact Board, which shall exercise powers and responsibilities as set forth in this Article.

B. Membership.

1. The Board shall consist of three members. One member shall be appointed by the Governor of the State of Montana or, in lieu of such appointment, shall be the Governor. The salary and expenses of that member shall be paid by the State. One member shall be appointed by the Chairman of the Tribes, or in lieu of such appointment, shall be the Tribal Chairman. The salary and expenses of that member shall be paid by the Tribes. The third member shall be selected by agreement of the other two members. The salary and expenses of that member and all other expenses of the Board shall be shared equally by the State and the Tribes subject to the availability of funds. Each member duly appointed or selected shall hold office for a term of six years, and for so long thereafter until a successor shall be appointed or selected. The initial term of each member shall be staggered, with one member serving a six-year term, one a four-year term, and one a two-year term. The initial term of each member shall be chosen by lot, or by any other procedure and agreed upon in writing by the first three members of the Board. If the Governor or the Tribal Chairman serves on the Board, such person shall not serve on the Board beyond his or her term as Governor or Tribal Chairman.

2. Should the two appointed members fail to agree within sixty days of the effective date of this Compact or within thirty days after any vacancy occurs, on the selection of the third member, the following procedure shall be utilized:

(a) within five days each member shall nominate no more than five and no less than three persons to serve as a member of the Board;

(b) within fifteen days thereafter each member shall reject all but one of the persons nominated by the other member;

(c) the chief judge of the United States District Court for the District of Montana shall select the third member of the Board from the remaining two nominees. If the chief judge declines for any reason to select the third member, the chief justice of the Montana Supreme Court shall make the selection from the remaining two nominees.

3. Vacancies on the board shall be filled by appointment of a person to serve the unexpired term of the member whose seat has become vacant. If the member appointed by the Governor becomes unable or unwilling to serve on the Board, the Governor shall make the appointment within fifteen days. If the member appointed by the Tribal Chairman becomes unable or unwilling to serve, the Tribal Chairman shall make the appointment within fifteen days. If the third member of the Board becomes unable or unwilling to serve on the Board, the remaining members shall fill the vacancy under the procedure set forth in paragraphs 1 and 2 of this section.

C. Quorum and Vote Required. Two members of the Board shall constitute a quorum if reasonable notice has been provided in advance to the absent member. Meetings may be in person or, in appropriate circumstances, by telephone. All Board decisions shall be by a majority of the Board, shall be in writing and, together with any dissenting opinions, shall be delivered to all parties in the proceeding before the Board, and to both Parties to this Compact.

D. Jurisdiction of the Board. The Board shall have exclusive jurisdiction, only as provided in this Compact, to resolve any controversy over the use of ground water to which this Compact pertains, any controversy over the use of surface water within the Reservation or from any tributary of the Missouri River that flows through or adjacent to the Reservation, except the mainstem of the Milk River, and any controversy as to the meaning of this Compact between: (i) on the one hand, the Tribes or any person or persons claiming a right to use the Tribal Water Right; and (ii) on the other hand, the State or any person or persons claiming a right to use water under the laws of the State.

E. Powers and Duties of the Board.

1. The Board shall have power to administer oaths to witnesses, to take evidence under oath, and to issue subpoenas to compel the attendance of witnesses or for the production of books, records, documents and other evidence. The courts of the Tribes and the State shall enforce any subpoena issued by the Board in the same manner as prescribed by the laws of the Tribes and the State for enforcing a subpoena issued in a civil action by courts of the Tribes and the State.

2. The Board shall hold hearings in proceedings before it and shall give advance notice to the Tribes, the State and all parties to any proceeding personally or by registered mail not less than five days before any hearing. Appearance at a hearing waives such notice. The Board may hear and determine the controversy upon the evidence produced notwithstanding the failure of a party duly notified to appear. The Tribes, the State and all parties to the proceeding are entitled to be heard, to present evidence material to the controversy, to cross-examine witnesses appearing at the hearing, and to be represented by counsel at their own expense.

3. The Board may enter an order after hearing granting any party to the dispute before it temporary or preliminary injunctive relief, or any other relief which the Board deems appropriate except money damages. The Board or any party to a proceeding before the Board may invoke the jurisdiction of a court of competent jurisdiction to enforce any temporary or preliminary injunction so issued by the Board by filing a petition for enforcement naming the enjoined person as respondent. Upon filing the petition, the court shall enter any order it deems appropriate for enforcement of the injunction ordered by the Board, including but not limited to injunctive relief on such terms as to bond or otherwise as it deems proper for the security of the rights of the enjoined party. The United States, the State, and the Tribes shall not be required to post any bond. The court may appoint a water commissioner or master to monitor compliance with such relief.

4. The Board shall adopt rules and regulations to govern its procedures and to carry out its responsibilities under this Compact. Such rules and regulations must be consistent with all provisions of this Compact. All records of the Board shall be open to public inspection except for privileged information.

5. The Board may employ or seek assistance of such clerical or other personnel and may establish such offices as it deems necessary for the performance of its functions according to this Compact. Pending the establishment of a principal office, the Board's office shall be located at Fort Peck Agency of the Bureau of Indian Affairs.

6. The annual budget of the Board shall be subject to approval of the Parties to this Compact and to the availability of funds appropriated by the Parties.

F. Review and Enforcement of Board Decisions.

1. Decisions by the Board shall be effective immediately, unless stayed for a period of time prescribed by the Board. On application of a party within a reasonable time, but in any event no more than ninety days after a decision is rendered, the Board may modify or correct any decision:

(a) where there was an evident material miscalculation of figures or an evident material mistake in the description of any person, thing or property referred to in the decision;

(b) where the decision is imperfect in a matter of form not affecting the merits of the controversy; or

(c) where the decision requires clarification.

2. Any party before the Board may, within ten days of any final decision, apply to the Board to modify or set aside any aspect of the decision. Notice of such application shall be served personally or by registered mail upon all parties to the proceeding. Any other party shall have ten days within which to respond to the application. The Board shall act on such application within ten days after a response is filed or, if no response is filed, within fifteen days after the application is filed. If the Board fails to act within the time limitations set forth in this paragraph, the application shall be deemed denied. The time for appeal provided in paragraph 3 of this section shall not begin to run until the application is determined as provided in this paragraph.

3. Any party before the Board may appeal any final decision by the Board to a court of competent jurisdiction within thirty days of such decision. The notice of appeal shall be filed with the Board and served personally or by registered mail upon the Tribes, the State and all parties to the proceeding before the Board, and all such persons shall thereafter have the right to participate in the appeal.

4. In any appeal, the Board's decision shall be presumed to be valid, and may be vacated by the court only on one of the following grounds:

(a) the decision is not supported by substantial evidence;

(b) the decision was procured by corruption, fraud or undue means;

(c) there was evident partiality or corruption by the Board or by any member;

(d) the Board was guilty of misconduct in refusing to hear the dispute, or in refusing to hear evidence pertinent and material to the controversy, or any other clear misbehavior by which the rights of any party have been substantially prejudiced;

(e) the Board exceeded its authority under the terms of this Compact; or

(f) the decision is contrary to law.

5. Unless an appeal is timely filed as provided in paragraph 3 of this section, any decision of the Board shall be confirmed or enforced by any court of competent jurisdiction on petition of the Board, the Tribes, the State or any party before the Board in the proceeding in which the decision was made.

6. A court of competent jurisdiction in which a timely appeal is filed pursuant to paragraph 3 of this section, or in which a petition to confirm or enforce is filed pursuant to paragraph 5 of this section, may order such temporary or permanent relief as it considers just and proper.

7. An appeal may be taken from any decision of the court in which a timely appeal is filed pursuant to paragraph 3 of this section, or in which a petition to confirm or enforce is filed pursuant to paragraph 5 of this section, in the manner and to the same extent as from orders or judgments of the court in a civil action.

8. In any appeal or petition to confirm or enforce the Board's decision, the Board shall file with the court the record of the proceedings before the Board.

G. Waiver of Immunity. The Tribes and the State hereby waive their respective immunities from suit, including any defense the State shall have under the Eleventh Amendment of the Constitution of the United States, to permit the appeal or judicial enforcement of Board decisions as provided in this Compact, except that such waivers shall not extend to any action for money damages including costs and attorneys' fees as a result of such judicial action.

ARTICLE VII
FINALITY AND EFFECTIVENESS OF COMPACT

A. Ratification. This Compact shall become effective as to both parties when ratified by the Legislature of the State of Montana and the Fort Peck Tribal Executive Board and approved by the United States Departments of Justice and the Interior. Ratification by the State and by the Tribes is irrevocable, and this Compact may not be modified in any manner whatsoever except with the joint consent of the legislative body of both Parties.

B. Incorporation into Decrees and Disposition of Federal Suits.

1. The Parties and the United States shall petition for incorporation of this Compact into the preliminary decrees and final decrees in any state water court proceedings to adjudicate any right to the use of water to which this Compact pertains, and this Compact may not be modified in any manner whatsoever without the consent of both Parties as provided in section A of this Article. The United States shall not be bound by provisions of this Compact until it is incorporated into the final decree, as provided in this section.

2. This Compact shall only be filed as a proposed consent decree in United States v. Aageson, Civ. No. 79-21-GF (D. Mont.), or United States v. Aasheim, Civ. No. 79-40-BLG (D. Mont.) if there is a final determination by the state courts that they lack jurisdiction over, or that the state proceedings are inadequate to adjudicate, some or all of the water rights asserted in either of the above cases. Upon a final determination that the state courts have jurisdiction over, and that the state proceedings are adequate to adjudicate all of the water rights in the above cases, the United States and the Parties will immediately execute a joint motion pursuant to Rule 41(a) of the Federal Rules of Civil Procedure to dismiss with prejudice and on their merits all claims by the Tribes and the United States on behalf of the Tribes in the pending cases.
