Wyo. Stat. § 41-3-609: Commissioners; disqualification for personal interest or prejudice.

Whenever an affidavit is filed with the state engineer by a water user stating that the water commissioner of a district has a personal interest or prejudice in the use of water from a stream and that the person making the affidavit believes that because of the commissioner's interest or prejudice he cannot obtain a fair and just division of water, the state engineer may designate a water commissioner from another district as substitute commissioner.
