(1) If the owners fail to make the modifications within the time limits set by the Water Resources Commission, or to institute their appeal or to comply with the decree of the appellate court in case an appeal is taken, the commission shall issue an order in writing to the owners directing that the gates be kept open, or an opening made in the dam if necessary, or that the structure shall not be used for the storage, restraint or conveyance of water until the modifications have been made.

(2) No owner shall refuse to comply with the orders of the commission or the decree of an appellate court.

(3) In case of noncompliance, the commission shall direct the watermaster or other authorized assistant to carry out the orders, or the commission may file a copy of the commission's order with the Attorney General or with the district attorney of the county within which the works are located. The Attorney General or district attorney shall bring proceedings in the name of the state, in the circuit court of the county within which the works or any part thereof are situated, to abate the offending works. The court, after a full hearing on the matter, may declare the works a nuisance and order their removal, or order any repairs or alterations, and may enforce its orders in the manner provided by law.
