ARTICLE V. Lake Tahoe Basin A. The right of the United States or its agent to store waters in Lake Tahoe between elevations 6,223.0 and 6,229.1 feet (Lake Tahoe datum) and to release said stored waters for beneficial uses downstream from Lake Tahoe Basin is hereby ratified and confirmed subject to the rights granted in Section D of this article. B. It is agreed by the states subject to the consent of the head of the federal agency having jurisdiction thereof, that an overflow weir of approximately 140 feet in length with a crest elevation of 6,223.0 feet, Lake Tahoe datum, upstream from the Lake Tahoe outlet gates shall be constructed and installed with necessary channel improvements within four years from the effective date of this compact provided that should the commission decide that it is in the best interests of each of the two states, it may extend such period for such additional period or periods as it may deem reasonable. The cost of this installation shall be borne by the States of California and Nevada in equal amounts. As used herein, Lake Tahoe datum shall be measured with respect to the top surface of the hexagonal brass bolt seven-eighths inch in diameter, projecting one inch from the vertical face of the southerly concrete abutment wall of the present existing Lake Tahoe Dam, at approximately 3.2 feet below the top of the wall and approximately in line with the upstream ends of the cutwaters of the concrete piers between the sluiceways of the dam. This surface of the brass bolt is presumed for the purposes of the compact to have an elevation 6,230.0 feet Lake Tahoe datum, notwithstanding that it was determined by the U.S. Geological Survey on November 15, 1960, to be at an elevation of 6,228.86 feet above sea level datum of 1929. C. The storage rights in Lake Tahoe shall be operated alone or in conjunction with other reservoirs so as to minimize the period and duration of high and low water elevations in Lake Tahoe, provided that exchanges of water or releases between Lake Tahoe and other reservoirs shall not measurably impair the intended purpose of such reservoirs. D. Upon construction of the overflow weir provided for in Section B of this article, the total annual gross diversions for use within the Lake Tahoe Basin from all natural sources including ground water and under all water rights in said basin shall not exceed 34,000 acre-feet annually, of which 23,000 acre-feet annually is allocated to the State of California for use within said basin, and 11,000 acre-feet annually is allocated to the State of Nevada for use within said basin. After use of the water allocated herein, neither export of the water from the Lake Tahoe Basin nor the reuse thereof prior to its return to the lake is prohibited. This allocation is conditioned upon the construction of the overflow weir; however, it is recognized that there may well be a period of time between the effective date of the compact and the construction of the overflow weir; during that period of time both states shall be permitted to use waters within the Lake Tahoe Basin subject to the same conditions, both as to place of use and amounts of use, as are provided in this Article V. E. In addition to the other allocations made by this compact, transbasin diversions from the Lake Tahoe Basin in both states existing as of December 31, 1959, may be continued, to the extent that such diversions are recognized as vested rights under the laws of the state where each such diversion is made. The diversion of a maximum of 3,000 acre-feet per annum from Marlette Lake for use in Nevada is hereby recognized as an existing transbasin diversion within the meaning of this Section E. F. Pumping from Lake Tahoe Basin for the benefit of downstream users within the Truckee River Basin shall be permitted only in the event of a drouth emergency as declared by the commission to the extent required for domestic, municipal, and sanitary purposes, and when it is determined by the commission that all other water available for such uses from all sources is being so utilized. In the event of such declaration of emergency, use of this water for such purposes shall have priority over use of water for any other purpose downstream from Lake Tahoe Basin. Pumping shall be done under the control and supervision of the commission and water pumped shall not be charged to the allocation of water to the Lake Tahoe Basin made herein. ARTICLE VI. Truckee River Basin The following allocations of water of the Truckee River and its tributaries, including Lake Tahoe releases, are hereby made in the following order of relative priority as between the states: A. There is allocated to Nevada water for use on the Pyramid Lake Indian Reservation in amounts as provided in the 1944 Truckee River Decree (Final Decree in United States vs. Orr Ditch Company, et al. United States District Court for the District of Nevada, Equity No. A3). By appropriate court order, the United States, for and in behalf of the Pyramid Lake Indians shall have the right to change points of diversion, place, means, manner, or purpose of use of the water so allocated so far as such change may be made without injury to the allocations to either state. B. There is allocated to California: 1. The right to divert within the Truckee River Basin in California 10,000 acre-feet of water per calendar year which may be stored in reservoirs at times when the flow in the channel of the Truckee River at the United States Geological Survey Gauging Station at or near the California-Nevada state line exceeds 500 cubic feet per second; provided that such diversions shall not in the aggregate exceed 2,500 acre-feet in any calendar month and the amount of such storage in any one reservoir, except Donner Lake, shall not exceed 500 acre-feet of active storage capacity. 2. The amount of water as decreed to the Sierra Valley Water Company by judgment in the case of United States vs. Sierra Valley Water Company, United States District Court for the Northern District of California, Civil No. 5597, as limited by said judgment. 3. Six thousand acre-feet of water annually from the conservation yield of Stampede Reservoir having a storage capacity of 225,000 acre-feet, subject to the execution of a contract or contracts therefor with the United States of America. California may divert all or any portion of said 6,000 acre-feet of conservation yield from Stampede Reservoir directly or by exchanges from any source on the Truckee River or its tributaries or from Lake Tahoe. California shall be allowed to deplete this allocation; provided, that in ascertaining the amount of depletion, credit for return flow shall be limited to the amounts of water which can be measured as a contribution to the Truckee River system. 4. If and when the water allocated to California in subparagraphs 1 and 3 of this section and in Article V is being used, or such use appears imminent, the commission shall permit California to develop additional yields of water for use in California, either directly or by exchange subject to the following limitations: (a) All existing beneficial uses of water for domestic, municipal, industrial, and agricultural purposes in Nevada as determined by Nevada law as of that time together with the yield of Stampede Reservoir in excess of 6,000 acre-feet shall be recognized and not impaired by the development of such additional yield. (b) Additional yields developed for use in California shall be limited to an amount not to exceed an aggregate of 10,000 acre-feet annually, and such development shall be for domestic, municipal, and industrial uses solely. California shall be allowed to deplete this allocation; provided, that in ascertaining the amount of depletion, credit for return flow shall be limited to the amounts of water which can be measured as a contribution to the Truckee River system. (c) The right of the commission to permit Nevada to share in such additional yield upon participation by Nevada in bearing a proportionate cost of developing such additional yield. C. The right to store in Prosser Creek Reservoir a maximum of 30,000 acre-feet of water annually with the priority as set forth in California State Water Rights permit 11666 and to release water therefrom as set forth in said permit and any license which may be issued thereunder is hereby recognized and confirmed. D. There is allocated to Nevada all water in excess of the allocations made in Sections B and C of this article. ARTICLE VII. Carson River Basin The following allocations of water of the Carson River and tributaries are hereby made in the following order of priority as between states: A. There is allocated to the State of California: 1. The right to divert from the natural flow of the West Fork Carson River and its tributaries for existing nonirrigation uses, and for direct irrigation use commencing on March 15 and ending on October 31 of each year on presently irrigable lands determined to be approximately 5,600 acres, an aggregate flow of water equal to a 30-day average of 3 c.f.s. per 100 acres or 168 c.f.s. for the area as a whole; provided that the 3 c.f.s. per 100-acre limitation shall not prevent greater rates of diversion for those areas which have an established greater rate of use; provided further, however, that the maximum aggregate diversion shall not exceed 185 c.f.s. measured at the points of diversion. Provided, however, diversions for use downstream from the western boundary of Section 34, Township 11 North, Range 19 East, Mount Diablo Base and Meridian, shall be subject to the following limitations: (a) Whenever, after the first Monday in May or any day in that week or alternate weeks thereafter of any year the flow of the West Fork of the Carson River at said western boundary shall have fallen below 175 cubic feet per second, then, until October 31 next, water users in California who divert from the West Fork of the Carson River downstream from said western boundary shall rotate all or any portion of the natural flow of the West Fork of the Carson River necessary to satisfy the demand of Nevada lands with water users in Nevada every other week beginning with the week following that in which water is used in Nevada, and during each rotation period said California users shall be entitled to divert the natural flow of the West Fork of the Carson River during their rotation weeks. (b) Rotation between water users in California and Nevada on the West Fork of the Carson River may be terminated in whole or in part upon approval of the commission for such termination, upon provision being made so that sufficient water is available by storage or exchange to assure that the water users in Nevada will receive at the same time the flow of water which would have been available to the Nevada water users under rotation. (c) Stock water, domestic water, and water for fire protection purposes may be diverted downstream from said western boundary from the natural flow of the West Fork of the Carson River at all times by owners of irrigation water rights in California whose lands are contiguous to the West Fork of the Carson River; provided, however, that such diversion shall be limited to the amounts actually required to deliver water for such purposes, and any excess over the amount so diverted shall be returned to the West Fork of the Carson River whenever practicable. Water diverted under this provision shall not be converted to any other use. The commission or its designee shall rule on any challenge relative to the necessity and amount of water required for such purposes. 2. The right to divert from the natural flow of the East Fork Carson River and its tributaries for existing nonirrigation uses, and for direct irrigation use commencing on March 15 and ending on October 31 of each year on presently irrigable lands determined to be approximately 3,820 acres, an aggregate flow of water equal to a 30-day average of 3 c.f.s. per 100 acres or 115 c.f.s. for the area as a whole; provided that the 3 c.f.s. per 100-acre limitation shall not prevent greater rates of diversion for those areas which have an established greater rate of use; provided further, however, that the maximum aggregate diversion shall not exceed 115 c.f.s. measured at the points of diversion. 3. There is allocated to the State of California the right to store 2,000 acre-feet of water per annum within Alpine County for supplemental use on presently irrigated lands within said county adverse to Lahontan Reservoir but subject to all other existing uses in Nevada. Water stored pursuant to this section remaining at the end of the year shall be deemed to have been stored in the succeeding year. B. There is allocated to the State of Nevada: 1. The right to divert water from the natural flow of the Carson River and its tributaries during the period commencing March 15 and ending October 31 of each year at the rate of 3 c.f.s. per 100 acres for use on presently irrigated lands in the area above Lahontan Reservoir determined to be approximately 41,320 acres. The rate of 3 c.f.s. per 100 acres is based on a 30-day average for the area as a whole and shall not prevent greater rates of diversion for those areas that have an established greater use; provided that the aggregate diversion measured at the points of diversion shall not exceed 700 c.f.s. on the East Fork of the Carson River, 300 c.f.s. on the West Fork of the Carson River, and 220 c.f.s. on the Main Carson River below the confluence of the East and West Forks. The combining and exchanging of the use of water between ditches and among users shall be permitted at all times and shall be required whenever necessary in order to obtain reasonable economy in the use of the water of the river or other streams, or in order to give to each ditch or user a more advantageous irrigation head. 2. Subject to allocations made in subsection B.1 and Section C of this article, the right to divert water from the Carson River for irrigation use either by direct diversion or by storage in Lahontan Reservoir or other existing reservoirs for use on the Newlands Project. C. There is allocated to each state the right to store water in existing reservoirs upstream from Lahontan Reservoir to the extent of existing capacity with the appropriate priority with respect to natural flow rights upstream from Lahontan Reservoir under applicable state law, and use such stored waters on the lands in each state to which the storage is appurtenant. D. Additional yields shall be available for development under the currently authorized Washoe Project from water available in excess of existing beneficial uses recognized by Nevada law, or under other new projects upon a determination by the commission that there is water available on the Carson River and its tributaries in excess of that required to satisfy existing beneficial uses in Nevada as determined by Nevada law as of the time of authorization or construction of such new projects. Such additional yields shall be allocated between the states with equal priority, 20 percent of which shall be allocated to California and 80 percent to Nevada. Each state shall have the right to participate in any development project by bearing a proportionate cost of such development. In the event that joint developments are found to be not feasible or desirable, each state may develop separately its proportionate share of the remaining water. E. Except as provided by Article X of this compact, the waters of the Carson River shall not be used in areas outside the Carson River Basin. ARTICLE VIII. Walker River Basin A. Allocation to Present Rights and Uses 1. Except as the rights of the Walker River Irrigation District may be limited by subsections 2 and 3 below, the provisions of the decree in the case of United States v. Walker River Irrigation District, et al., United States District Court for the District of Nevada Equity No. C-125, filed April 15, 1936, as amended by the Order of the Honorable A.F. St. Sure, dated April 24, 1940, hereafter called Decree C-125 are hereby recognized and confirmed. 2. The rights of the Walker River Irrigation District to store water of the West Walker River in Topaz Reservoir with a storage capacity of 59,000 acre-feet, under Part VIII of Decree C-125 and under any other basis of right, and to use such water, are hereby recognized and confirmed, subject to the following: (a) The maximum quantity of water which can be diverted annually to storage is 85,000 acre-feet. No more than 85,000 acre-feet of water less reservoir evaporation can be rediverted for use within the district annually. The 85,000 acre-feet amount so allowed to be diverted to storage and rediverted to use include water used under direct diversion rights in Decree C-125 acquired by said district prior to 1964. For the purpose of this provision annually means the period from November 1 through October 31 of the following year. (b) The maximum rate of diversion to such reservoir under such rights is 1,000 c.f.s. (c) For the purpose of determining the availability of water to satisfy rights junior to the Topaz Reservoir storage rights of the Walker River Irrigation District, or for division between the states as unused water, water which has been stored, or is available for storage in and can be physically diverted to such reservoir under such reservoir rights but is released or is allowed to pass through the reservoir and is not rediverted to use in Nevada, shall be deemed to have been held in storage; provided, that until a new major storage project is constructed on the West Walker River, the foregoing shall not apply to the extent that said district with the concurrence of the watermaster determines, prior to the release or passing through of such water from Topaz Reservoir in any year, that it is necessary to release or pass through such water in order to provide storage space in Topaz Reservoir as a means of protecting lands in Nevada against flood damage later in the year. 3. The rights of the Walker River Irrigation District to store water of the East Walker River in Bridgeport Reservoir with a storage capacity of 42,000 acre-feet, under Part VIII of Decree C-125 and under any other basis of right, and to use such water, are hereby recognized and confirmed, subject to the following: (a) The maximum quantity of water which can be diverted to storage in any year is 57,000 acre-feet. No more than 57,000 acre-feet of water less reservoir evaporation can be rediverted for use within the district in any year. The 57,000 acre-feet amounts so allowed to be diverted to storage and rediverted to use include water used under direct diversion rights in said decree acquired by said district prior to 1964 except for water used under such rights prior to 1964 on lands owned by said district in Bridgeport Valley. For the purpose of this provision year means the period from November 1 of one calendar year to October 31 of the following calendar year. (b) Water of the East Walker River and its tributaries may, adversely to the Bridgeport Reservoir storage rights hereinabove recognized and confirmed, be stored upstream from said reservoir in any year, for later use after the spring flood of the year in which the water was so stored, under rights junior to said reservoir rights; provided, that when the Walker River system is put on priority under Decree C-125 after the annual spring flood, or upon demand made prior to the spring flood for water necessary to satisfy early season demand, the watermaster shall make an accounting and water shall be released from said upstream storage in such amounts as determined by the watermaster to be necessary to satisfy said reservoir rights to the same extent as they would have been satisfied in the absence of said adverse upstream storage. 4. (a) There is allocated to each state respectively the amount of existing diversions and uses of water of the Walker River Basin diverted upstream from Weber Reservoir and not specifically covered in Decree C-125, provided, that this allocation shall not include water distributed under the historical administration of Decree C-125 in excess of the rights set forth in Decree C-125 to lands having rights thereunder. In making this allocation, it is recognized that the amounts of water allocated and the respective priorities are not presently known with certainty. The commission shall as soon as practicable after its effectuation provide for an investigation, either with its own staff or by other agencies or persons, to ascertain with certainty the amounts of water and priorities of such uses. As between the respective states, the priorities shall be determined as follows: In cases of use not under state-recognized rights, the priorities shall be the date of initiation of use; in cases of use under state-recognized rights, the priorities shall be as provided under the law of the state where the diversion is made. Upon approval by the commission, the results of the investigation shall be binding as to the allocation to each state hereunder. (b) In addition to rights recognized in subsection A.1 of this article there is allocated to Nevada for use on the Walker River Indian Reservation a maximum of 13,000 acre-feet per year for storage in Weber Reservoir and later rediversion to use and in addition 9,450 acre-feet per year to be diverted from natural flow. Both allocations shall have a priority of 1933. The season for diversion of water to storage shall be from November 1 to October 31 of the following year. The season for diversion of water directly for use shall be from March 1 to October 31 and at a maximum rate of 60 cubic feet per second. For the purpose of determining the availability of water to satisfy rights junior to this allocation or for division between the states as unused water, water which has been stored, or which can be physically stored or diverted to use under this allocation but is released or is allowed to pass through Weber Reservoir and is not rediverted to use on the Walker River Indian Reservation, shall be deemed to have been held in storage or used; provided, that the foregoing shall not apply to the extent that the appropriate representative of said reservation with the concurrence of the watermaster determines prior to the release or passing through of such water from Weber Reservoir in any year, that it is necessary to release or pass through such water in order to provide storage space in Weber Reservoir as a means of protecting lands in Nevada against flood damage later in the year; provided, further, that the foregoing shall not apply to passage of water of inferior quality to the extent that such passage may be necessary to maintain the water of suitable quality for irrigation on said reservation as determined by the commission. Water of the Walker River and its tributaries may, adversely to the Weber Reservoir storage rights hereinabove recognized and confirmed, be stored upstream from said reservoir in any year, for later use after the spring flood of the year in which the water was so stored, under rights junior to said reservoir rights; provided, that when the Walker River system is put on priority under Decree C-125 after the annual spring flood, or upon demand made prior to the spring flood for water necessary to satisfy early season demand, the watermaster shall make an accounting and water shall be released from said upstream storage in such amounts as determined by the watermaster to be necessary to satisfy said reservoir rights to the same extent as they would have been satisfied in the absence of said adverse upstream storage. 5. In addition to rights recognized in subsections A.1 and A.4(a) above, there is allocated to California water of the West Walker River as follows: (a) When all direct diversion rights under Decree C-125 are being satisfied and simultaneously water of the West Walker River is being diverted to storage pursuant to the Topaz Reservoir storage rights recognized and confirmed in subsection 2 of this Section A, but there is not flow in excess of that required to fully satisfy Topaz Reservoir storage rights, diversions in Antelope Valley in excess of the amounts to which Antelope Valley lands are entitled under Decree C-125 shall be permitted by the watermaster for such periods and in such amounts as, in the sound professional judgment of the watermaster, will not cause, on an overall irrigation season basis, any discernible net reduction in the amount of water available to satisfy said Topaz Reservoir storage rights. (b) Such excess diversions may be used only on Antelope Valley lands entitled to water under Decree C-125 which can be served from the ditch systems existing as of the effective date of this compact. (c) The allocation in this subsection 5 shall terminate after construction of a new major storage project on the West Walker River upstream from Antelope Valley. B. Allocation of Unused Water 1. The term unused water includes all waters of the Walker River and its tributaries in excess of the amounts allocated, or required for satisfaction of rights and uses recognized and confirmed, as provided under Section A of this Article VIII, except that there shall be excluded therefrom natural flow which is not physically available above the head of Mason Valley. There is allocated to the State of California 35 percent of such unused water, and there is allocated to the State of Nevada 65 percent of such unused water. The allocation to each state provided herein in this subsection B.1 shall be equal in priority. (a) The reregulation by storage of waters allocated for storage shall not be considered as the development of unused water. 2. Neither state shall be precluded from constructing works for the control, use and development of the water allocated pursuant to subsection B.1 of this article for optimum use of water. 3. While separate development may be undertaken by either state for surface storage of unused water of the West Walker River so allocated, the State Engineer of the State of Nevada and the Department of Water Resources of the State of California shall cooperate in a joint review of all potential developments of unused water of the West Walker River so allocated in subsection B.1 of this Article VIII and shall prepare and present a report of the benefits to be obtained, and other relevant data from each such development to the commission or if the commission has not yet become operative, to the joint commission which negotiated this compact, at a public hearing or hearings held at times and places within the Walker River Basin set by the commission or said joint commission. (a) Should a separate surface storage project or projects be constructed in Nevada to develop Nevadas share of the unused water of the West Walker River, California may thereafter store and use said unused water allocated to Nevada adverse to such Nevada storage projects, provided that, without charge to Nevada, California makes available for consumptive use in Nevada, water in the same amounts, at the same times, and in the same places as would have been available for use in Nevada from such Nevada storage projects had California not so stored and used said unused water allocated to Nevada; and provided further that Nevada shall not be deprived of water required for: (1) maintenance of a minimum reservoir level for the preservation of fish life and (2) nonconsumptive uses which are found by the commission to be in the public interest of the Walker River Basin as a whole. (b) From time to time after construction of each surface storage project upstream from Topaz Reservoir, for development of the unused water allocated herein, the commission shall determine the amounts of water which may be diverted and used in each state pursuant to its allocation as the result of the construction and operation of such project. In making such determination the commission shall compute any increase of yield of previously constructed reservoirs which may result from operation of such project constructed to develop unused water and shall include such increase in the amounts of water which may be diverted and used in each of the two states pursuant to its allocation of unused water. 4. Return flow to the Walker River or its tributaries from any source shall be deemed to be natural flow. 5. Unused water shall be used only: (a) Within the Walker River Basin; (b) Within the portion of Artesia Lake Basin south of the northern township line of Tier 12 North and west of a line one mile east of the eastern range line of Range 23 East, Mount Diablo Base Line and Meridian; (c) Within the portion of Mason Valley and Adrian Valley south of the northern township line of Tier 15 North, Mount Diablo Base Line; (d) Within the area tributary to Topaz Lake; or (e) Any combination of the above areas. C. Watermaster 1. A single watermaster shall have the responsibility and power to administer: (a) all rights and uses of water of the Walker River Basin recognized in Section A of this Article VIII, including rights under Decree C-125, (b) the allocation between the states provided for in this compact of water of the Walker River Basin in excess of that necessary to satisfy such rights and uses, and (c) all rights acquired to use water so allocated. 2. The watermaster shall be nominated by the commission as soon as practicable after this compact goes into effect, but his appointment shall not become effective until approved and confirmed by the Federal District Court for the District of Nevada, it being the intent of this compact that only a person satisfactory to both the commission and said court be the watermaster under this compact and under Decree C-125. At any time either the commission or said court may terminate the appointment of the person serving as watermaster by adopting an appropriate resolution or order, and notifying the other and the watermaster thereof. When a vacancy occurs by such action or by the death or resignation of the person serving as watermaster, a successor shall be selected by the same procedure as provided for the original appointment. 3. Until appointment of the watermaster becomes effective by approval and confirmation of said court, either as to the original selection of the watermaster or subsequent selections to fill a vacancy, a person designated by the commission shall have interim responsibility and power to administer the allocation between the states referred to in subsection 1(b) above and all rights and uses other than the rights under Decree C-125, and the rights and uses under Decree C-125 shall be administered on an interim basis as may be provided by said court. 4. Actions and decisions of the watermaster as to the administration of the rights under Decree C-125 shall be subject to review and modification by said court. Actions and decisions of the watermaster as to the administration of the allocation between the states referred to in subsection 1(b) above and of all rights and uses other than rights under Decree C-125 shall be subject to review and modification by the commission. 5. Said court is requested to appoint a six-member advisory board composed of one person each representing: (1) the East Walker River Basin in California, (2) the West Walker River Basin in California, (3) the East Walker River Basin in Nevada, (4) the West Walker River Basin in Nevada, (5) the Main Walker River Basin in Nevada, and (6) the Walker River Indian Reservation. The watermaster shall prepare an annual budget of proposed expenditures for personnel, equipment, supplies, and other purposes deemed by him to be necessary to carry out his functions. In the formulation of said budget the watermaster shall consult with said advisory board. In the event that said advisory board is not in agreement with the budget proposed by the watermaster, it shall so advise said court. Said budget shall require approval of both the commission and said court to become effective. 6. The expenditures attributable to administration of the rights under Decree C-125 shall be apportioned and collected in accordance with orders of said court. The expenditures attributable to administration of all other rights and uses of the water of the Walker River Basin under this compact shall be equitably apportioned among, and collected from, the users thereof by the watermaster under rules and regulations of the commission, and the commission shall have the power to enforce collection thereof by any reasonable means, including court action in any state or federal court of appropriate jurisdiction. The expenditures attributable to administering the allocation between the states referred to in subsection 1(b) above shall be borne by the commission as part of the expense under Article IV, subsection B.1 of this compact. ARTICLE IX. Ground Water and Springs A. Development and Use of Ground Water 1. Both states shall have the right to develop and use ground water within their respective boundaries; provided that development and use of ground water in one state shall not reduce the amount of water which the other state would have received under the allocation herein if ground water were not developed and used. 2. In the development and use of ground water pursuant to this article, wells or other methods of collecting underground water shall be constructed in a manner which will assure that water will not be drawn directly from allocated surface water. In the absence of proof to the contrary made to the commission, wells drilled within 500 feet from any perennial streams which are not sealed from the surface to a depth of at least 50 feet shall be deemed prima facie to draw directly from allocated surface water. B. Each state shall have the right to use water from springs; provided that the use of water from springs in one state shall not reduce the amount of water which the other state would have received under the allocations herein if water from springs were not used. C. Effect on Allocations 1. The commission shall have authority to take such action as it deems appropriate, so that the allocations of water made by this compact to either state shall not be adversely affected by ground water withdrawals or use of water from springs in the other state. 2. If either state claims that the development and use of ground water or water from springs in the other state reduces the amount of water which said state would have received under its allocation if such ground water or water from springs were not developed and used, it may file a protest with the commission in accordance with the rules of the commission. The commission is empowered to receive evidence on any protest and make its ruling thereon. ARTICLE X. Interbasin Transfers of Use Either state may use directly, by exchange, or otherwise its allocated waters of the Truckee River in the Lake Tahoe Basin or the Carson River Basin, or its allocated waters of the Carson River in the Lake Tahoe Basin or the Truckee River Basin. The commission shall have authority to take such action as it deems appropriate so that the allocations of water made by this compact to either state shall not be adversely affected by such use in the other state. Nothing herein shall preclude the use of Lake Tahoe as a physical facility to accomplish the use of Truckee River waters in the Carson River watershed or Carson River waters in the Truckee River watershed, but in no event shall the use of Lake Tahoe as such a physical facility be inconsistent with any provision of Article V of the compact. ARTICLE XI. Suppression of Evaporation A. Either state is entitled, but not obligated to participate in any project for the conservation of water through the suppression of evaporation. The yield of any such project shall be allocated to each state by the commission in such proportion as shall be determined by the commission, taking into consideration such factors as the commission deems pertinent. Such allocation of yield to each state shall be in addition to the waters allocated to each state by other provisions of this compact. B. Subject to the power of the commission to allocate the increased yield resulting from suppression of evaporation as set forth above, no existing property right shall be adversely affected except by agreement with the owner, or as may be otherwise permitted by state law. Nothing herein shall diminish or supersede any law of either state regarding water quality, including but not limited to conditions affecting fish and wildlife. ARTICLE XII. Coordination of Reservoirs A. The commission shall have the authority to prepare plans for the coordination of reservoirs and the method of implementation of any such plans prepared, and to approve the same and to review and revise such approved plans from time to time as the commission may deem appropriate. Prior to the preparation of any such plan and implementation or review or revision thereof, the owners of all reservoirs to be affected thereby shall be given the opportunity of participating in such preparation, review, or revision. B. Prior to the approval thereof, the commission shall provide for public hearings concerning such a plan, review, or revision upon such notice as the commission deems appropriate. C. Any owner of a reservoir shall have the right to refuse to participate in any such plan, or method of implementation, or review or revision thereof, and in such event such reservoir shall be excluded therefrom, and any plan or implementation or review or revision concerning other reservoirs as may be approved shall not adversely affect the use of the reservoir or the right to the use of water therefrom, which has been excluded. D. Owners of reservoirs may develop plans for coordination thereof, but shall give written notice to the commission at least 60 days prior to their implementation. ARTICLE XIII. Fish, Wildlife, and Recreation The use of waters for preservation, protection, and enhancement of fish, wildlife, and recreation is hereby recognized as an inseparable part of the public interest in the use of the waters of Lake Tahoe, Truckee, Carson and Walker River Basins in both states, and is, therefore, beneficial. ARTICLE XIV. Nonconsumptive Use Each state may use water for nonconsumptive purposes, including but not limited to flood control, recreation, fishery and wildlife maintenance and enhancement, and hydroelectric power generation, provided that such uses result in no discernible reduction in the water allocated to the other state. ARTICLE XV. Diversion and Exchange of Yield From Future Reservoirs Upon the construction of a surface storage project or projects to store unused water herein allocated, users who become entitled to the yield therefrom may, at any point where water is physically available, divert water to use subject to approval of the commission and conditioned upon providing water in exchange for such diverted water as directed by the commission, so that other users, including owners of reservoir storage or owners of interest in waters stored, receive their entitlement of water in time, place, and quality the same as if the diversion and exchange had not been made. ARTICLE XVI. Change of Point of Diversion, Manner, Purpose, or Place of Use Any change of point of diversion or of manner, purpose or place of use of the waters of the Carson, Truckee or Walker River Basins may be made in either state pursuant to state law or applicable court decree, provided that such change shall not adversely affect the allocation of water to the other state. Either state, if permitted by state law, may permit a change to other use of water formerly consumed by natural subirrigation on meadows. It shall be the duty of each state to initiate proceedings before the commission if it believes that such change in the other state would adversely affect its allocation. In the event of the initiation of such a proceeding a commission hearing shall be held and the person desiring the change shall have the burden of establishing that such change would not adversely affect the allocation to the complaining state. In the event the person desiring the change does not establish that such change would not adversely affect the allocation to the complaining state, the commission shall enter such order as it deems appropriate to assure that the allocation to the complaining state is not adversely affected. ARTICLE XVII. Imported Water The provisions of this compact respecting allocation of water are applicable solely to the waters of the Truckee, Carson, and Walker River Basins and the Lake Tahoe Basin. To the extent that either state imports into the Truckee, Carson or Walker River Basins or the Lake Tahoe Basin water from another river or source the state making the importation shall have the exclusive use of such imported water unless by written agreement between the states it is otherwise provided. Nothing herein shall preclude either state from using such imported water as replacement or exchange water to meet such conditions as may be imposed by the commission pursuant to the provisions of this compact. ARTICLE XVIII. Compact Effect A. Each state and all persons using, claiming, or in any manner asserting any right to the use of the waters of Lake Tahoe, Truckee River, Carson River, and Walker River Basins, shall be subject to the terms of this compact. B. The provisions of this compact shall be self-executing and shall by operation of law be conditions of the various state permits, licenses, or other authorizations relating to the waters of Lake Tahoe, Truckee River, Carson River and Walker River Basins. C. Nothing in this compact shall abridge, limit or derogate against any claim or right of anyone to the use of water in either state within the allocations to such state that could or may be made or established under state or federal law had this compact not been adopted; provided, that the place of use, under any such right, of water from any of the four basins covered by this compact shall be limited to such basin or such other areas outside such basin as are permissible places of use of water from such basin under this compact. D. Nothing in this compact shall be construed as granting to any person or entity the right to divert, store, or use water. ARTICLE XIX. Violations A. Violations or threatened violations of any of the provisions of this compact which come to the attention of the commission shall be promptly investigated by it. If after such investigation the commission determines further action is necessary it may take such action as it deems advisable including, but not limited to, the commencement of an action injunctive or otherwise in its own name in any court of general jurisdiction of the state where the violation has occurred or is threatened, or the United States District Court for the district where said violation has occurred or is threatened, or if it is determined by the commission appropriate to do so, refer the matter with its recommendations, if any, to an appropriate federal, state, or local official or agency or board for action. B. In any action concerned with any matter in which the commission has made a decision, the findings of the commission shall constitute prima facie evidence of the facts found. ARTICLE XX. Recourse to Courts Nothing in this compact shall be construed to limit or prevent either state or any person or entity from instituting or maintaining any action or proceeding, legal or equitable, in any court of competent jurisdiction for the protection of any right under this compact or the enforcement of its provisions, provided that in all matters in which the commission is given jurisdiction by this compact to make a decision no such court action shall be commenced until the matter has been submitted to the commission for decision and decided by it, unless a decision by the commission has been unreasonably delayed. ARTICLE XXI. Nonimpairment of Rights of United States Except as provided in Article XXII nothing in this compact shall be construed as: A. Affecting the obligations of the United States to the Indians and Indian tribes, or any right owned or held by or for Indians or Indian tribes which is subject to the jurisdiction of the United States. B. Affecting any rights or powers of the United States of America, its agencies or instrumentalities in or to the waters of the Truckee, Carson, or Walker River Basins or the Lake Tahoe Basin, or its capacity to acquire rights in and to the use of said waters. C. Subjecting any property of the United States, its agencies or instrumentalities to taxation by either state or subdivision thereof. D. Subjecting any property of the United States of America, its agencies or instrumentalities to the laws of any state to an extent other than the extent to which such laws would apply without regard to this compact.
