Wyo. Stat. § 41-7-411
The damages allowed to the owners of lands shall be paid or tendered before the commissioners shall be authorized to enter upon the lands, for damage to which the award is made, for the construction of any reservoirs, canals, ditches, or other work proposed thereon. If the owner is unknown or there shall be a contest in regard to the ownership of the lands, or the owner will not receive payment, or there exists a mortgage or other lien against the same, or the commissioners cannot for any other reason pay him, they may deposit the said damages with the clerk of the court, for the benefit of the owner, or parties interested, to be paid or distributed as the court shall direct, and such payment shall have the same effect as the tender to and acceptance of the damages awarded by the true owners of the land. This section shall not, however, prevent said commissioners, their agents, servants, and employees from going upon said lands to do any and all work found necessary prior to making their assessment of benefits and award of damages, and the trial on their report thereof.
