Wyo. Stat. § 41-3-304
Whenever the owner, manager or lessee of a reservoir, constructed under the provisions of this act, shall desire the use of the bed of the stream, or other water course, for the purpose of carrying stored or impounded water from the reservoir to the consumer, or shall desire the use of any ditch to carry, convey or transmit any of the stored or impounded water for the benefit of any person having the right to have the reservoir water carried, conveyed or transmitted through the ditch under the laws of this state, he shall, in writing notify the water commissioner of the district in which the stored or impounded water is to be used, giving the date when it is proposed to discharge water from the reservoir, its volume in acre feet and the names of all persons and ditches entitled to its use, and other matters as may be necessary to properly distribute the water. It shall then be the duty of the water commissioner to so adjust the headgates of all ditches of ditch companies or appropriators from the stream or water course, and the division boxes of individual consumers of water, not entitled to the use of the stored water, as will enable those having the right to secure the volume of water to which they are entitled. The commissioner shall not in any other manner interfere with the headgates or division boxes, except as otherwise provided by law. The water commissioner shall keep a true and just account of the time spent by him in the discharge of his duties as defined in this section, and it shall be the duty of the water commissioner or division superintendent to present a bill of one-half (1/2) the expense so incurred to the reservoir owner, manager or lessee, and if the owner, manager, or lessee shall neglect for three (3) days, after the presentation of the bills of costs, to pay the costs, the costs shall be made a charge upon the reservoir and shall be collected as delinquent taxes until the complete payment of the bill of costs has been made. Costs recovered under this section shall be paid into the general fund.
