Wyoming Statutes Title 41. Water § 41-3-314. Alterations or repairs of dams or diversion systems; emergency repairs or breaching

(a) In case of an emergency where the state engineer or his authorized representative declares that repairs or breaching of a dam or diversion system are immediately necessary to safeguard life and property, the necessary repairs or breaching shall be started immediately by the owner or by the state engineer or his representative at the owner's expense, if the owner fails to do so. The state engineer and emergency response agencies shall be notified at once of any changes in the physical conditions of the dam, diversion system, or reservoir which significantly increase the probability of failure of the dam or diversion works or the danger to life or property, proposed emergency repairs or breaching to be instituted by the owner. These reporting requirements shall apply only to cases in which an emergency has been declared pursuant to this subsection.

(b) If emergency repairs have been made and the emergency situation has passed, the owner shall commence all repairs necessary to return the dam or diversion system to a safe and usable condition, as provided in W.S. 41-3-308 through 41-3-310.

(c) All costs incurred by the state engineer during an emergency shall be payable by the owner or owners on receipt of the bill of costs from the state engineer. Costs not paid within thirty (30) days after presentation of the bill shall constitute a lien upon the dam or diversion system or other properties of the owner or owners and may be collected by appropriate action in any court of competent jurisdiction. The lien shall be filed as provided by W.S. 41-3-310(c).
