Wyo. Stat. § 41-3-726
Subdistricts may be organized upon the petition of the owner of real property, within or partly within and partly without the district, which petition shall fulfill the same requirements concerning the subdistricts as the petition outlined in W.S. 41-3-721 is required to fulfill, concerning the organization of the main district and shall be filed with the clerk of the court, and shall be accompanied by a bond as provided for in W.S. 41-3-722. All proceedings relating to the organization of such subdistricts shall conform in all things to the provision of this act relating to the organization of districts; provided, that not more than a majority of the owners of lands, having one-half or more of the aggregate assessed value of the lands in the proposed subdistrict, shall be required to sign the petition for the creation of a subdistrict, and not more than twenty-five percent (25%) of the owners of lands in the proposed subdistrict shall be required to sign the protesting petition against the creation of such subdistrict. Whenever the court shall by its order duly entered of record, declare the [or] decree such subdistricts to be organized, the clerk of said court shall thereupon give notice of such order to the directors of the district who shall thereupon act also as directors of the subdistrict. Thereafter, the proceedings in reference to the subdistrict shall in all matters conform to the provision of this act except that in the appraisal of benefits for the purpose of such subdistricts, in the issuance of bonds, in levying of assessments and in all other matters affecting only the subdistrict, the provisions of this act shall apply to the subdistrict as though it were an independent district, and it shall not in these things be amalgamated with the main district. The said petition for organization of a subdistrict shall also contain a statement of the amount or quantity of water for which said subdistrict desires to acquire the perpetual use and the amount of money that said subdistrict is willing to pay therefor, and the court shall, prior to the entry of its decree organizing any territory into a subdistrict obtain the verified consent of the board to furnish such perpetual use of water for the purposes therein specified to such subdistrict at a price and upon the terms mentioned in the petition, then the court shall be authorized to enter its decree of organization of such subdistrict.
