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.

(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.

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.

(iii) 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.
