N.D. Cent. Code § 61-07-28
When any irrigation district shall find it necessary to procure its supply of water for the irrigation of the lands within the district from outside the boundaries of this state, such district may enter into an agreement or contract with any state board, commission, or bureau, or with any person, association, company, corporation, limited liability company, or irrigation district, having the control and jurisdiction over the water of such other state, for water rights therein or for supplying the district with water sufficient for its irrigation needs. The making of such contract and the issuance of bonds or improvement warrants and the levying of assessments, or other method agreed upon for the payment of rights, franchises, or water charges to obtain the required supply of water shall be deemed valid, and of full force and effect, and shall have the same validity and legality as though the same rights and franchises existed wholly within this state.
