4. the quantity of water, in acre-feet, that passed the point of measurement in the stream during the period from October 1 to that given date.

D. All existing rights to the beneficial use of waters of the Yellowstone River in the states of Montana and North Dakota below Intake, Montana, valid under the laws of these states as of January 1, 1950, are hereby recognized and shall be and remain unimpaired by this compact. During the period May 1 to September 30, inclusive, of each year, lands within Montana and North Dakota shall be entitled to the beneficial use of the flow of waters of the Yellowstone River below Intake, Montana, on a proportionate basis of acreage irrigated.

  acreage irrigable under existing works; and

  potentially irrigable lands.

Article VI

Nothing contained in this compact shall be so construed or interpreted as to affect adversely any rights to the use of the waters of Yellowstone River and its tributaries owned by or for Indians, Indian tribes, and their reservations.

Article VII

A. A lower signatory state shall have the right, by compliance with the laws of an upper signatory state, except as to legislative consent, to file application for and receive permits to appropriate and use any waters in the Yellowstone River system not specifically apportioned to or appropriated by such upper state as provided in Article V; and to construct or participate in the construction and use of any dam, storage reservoir, or diversion works in such upper state for the purpose of conserving and regulating water that may be apportioned to or appropriated by the lower state. Provided, that such right is subject to the rights of the upper state to control, regulate, and use the water apportioned to and appropriated by it. And provided further, that should an upper state elect, it may share in the use of any such facilities constructed by a lower state to the extent of its reasonable needs upon assuming or guaranteeing payment of its proportionate share of the cost of the construction, operation, and maintenance. This provision shall apply with equal force and effect to an upper state in the circumstance of the necessity of the acquisition of rights by an upper state in a lower state.

B. Each claim hereafter initiated for an appropriation of water in one signatory state for use in another signatory state shall be filed in the office of the state engineer of the signatory state in which the water is to be diverted, and a duplicate copy of the application or notice shall be filed in the office of the state engineer of the signatory state in which the water is to be used.

C. Appropriations may hereafter be adjudicated in the state in which the water is diverted, and where a portion or all of the lands irrigated are in another signatory state, such adjudications shall be confirmed in that state by the proper authority. Each adjudication is to conform with the laws of the state where the water is diverted and shall be recorded in the county and state where the water is used.

Article VIII

A lower signatory state shall have the right to acquire in an upper state by purchase or through exercise of the power of eminent domain such lands, easements, and rights-of-way for the construction, operation, and maintenance of pumping plants, storage reservoirs, canals, conduits, and appurtenant works as may be required for the enjoyment of the privileges granted herein to such lower state. This provision shall apply with equal force and effect to an upper state in the circumstance of the necessity of the acquisition of rights by an upper state in a lower state.

Article IX

Should any facilities be constructed by a lower signatory state in an upper signatory state under the provisions of Article VII, the construction, operation, repairs, and replacements of such facilities shall be subject to the laws of the upper state. This provision shall apply with equal force and effect to an upper state in the circumstance of the necessity of the acquisition of rights by an upper state in a lower state.

Article X

No water shall be diverted from the Yellowstone River basin without the unanimous consent of all the signatory states. In the event water from another river basin shall be imported into the Yellowstone River basin or transferred from one tributary basin to another by the United States of America, Montana, North Dakota, or Wyoming or any of them jointly, the state having the right to the use of such water shall be given proper credit therefor in determining its share of the water apportioned in accordance with Article V herein.

Article XIV

The physical and other conditions characteristic of the Yellowstone River and peculiar to the territory drained and served thereby and to the development thereof have actuated the signatory states in the consummation of this compact, and none of them, or the United States of America by its consent and approval, concedes thereby the establishment of any general principle or precedent with respect to other interstate streams.

Article XV

This compact shall become operative when approved by the legislature of each of the signatory states and consented to and approved by the congress of the United States.

(a) to impair or affect the sovereignty or jurisdiction of the United States of America in or over the area of waters affected by such compact, any rights or powers of the United States of America, its agencies, or instrumentalities in and to the use of the waters of the Yellowstone River basin or its capacity to acquire rights in and to the use of said waters;

(b) to subject any property of the United States of America, its agencies, or instrumentalities to taxation by any state or subdivision thereof or to create an obligation on the part of the United States of America, its agencies, or instrumentalities, by reason of the acquisition, construction, or operation of any property or works of whatsoever kind, to make any payments to any state or political subdivision thereof, state agency, municipality, or entity whatsoever in reimbursement for the loss of taxes;

(c) to subject 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 these laws would apply without regard to the compact.
