Wyo. Stat. § 41-9-273
Upon receiving fifteen (15) days notice in writing, any railway company, across whose right-of-way or yard any such drain, ditch or levee is laid out shall open its right-of-way or yards, and permit said commissioners and their contractors, agents and employes to construct said drain, ditch or levee, across said right-of-way or yards. For every day that said railroad company fails, after the end of said fifteen (15) days, to open their said right-of-way or yard, as hereinbefore required, it shall forfeit twenty-five dollars ($25.00) to said drainage district, to be collected in an action, as other forfeitures are collected, or set off against any damages that have been awarded to such company. If said railway company fails to open its right-of-way or yard along the line of said drainage district, drain, ditch or levee, the commissioners may, at any time after the expiration of said fifteen (15) days, open such right-of-way and yard along the line of said drains, ditches and levees, and construct the same.
