Wyo. Stat. § 41-9-116
If it shall appear that the petition has so been signed, the court or judge shall so find, and order any necessary amendments thereto, and shall appoint three (3) suitable, competent persons as commissioners, and fix their preliminary bond. If the district is situated in two (2) or more counties, not more than two (2) of said commissioners shall reside in any one (1) of said counties. Ownership of land within the district shall not disqualify a person from acting as a commissioner. Provided, however, after the appointment of the first board of commissioners a majority of the owners of land within said district who own one-third in area of the lands within said district, shall petition the court asking that the commissioners of said district be elected by vote of the owners of land assessed in said district, the court shall make and enter an order fixing the time of the annual election for said district, prescribing the manner of giving notice of such election, and the manner in which such election shall be conducted, and may provide for cumulative voting; said order may provide for the election of one (1) commissioner for one (1) year and two (2) commissioners for two (2) years at the first election, succeeding commissioners to be elected for two (2) years; at such election every person, company or corporation owning land assessed for benefits within such district shall be entitled at such election to cast one (1) vote for each acre of land, or fraction thereof, owned by such person, company or corporation within said district and assessed for benefits therein; such order shall provide for voting by proxy, and such order may be modified from time to time upon petition as herein provided for the election of commissioners, and upon like petition such order may be revoked and thereafter such commissioners shall be appointed by the court.
