(a) When a drainage watercourse is impaired by a beaver dam, the commissioner shall take action to remove the impairment, if:
(1) the county board unanimously consents;
(2) the landowner approves;
(3) the commissioner agrees; and
(4) the action is financially feasible.
(b) In a county with unanimous consent of the county board of commissioners and approval of the landowner, the department shall take action agreed to by unanimous consent of the county board, the commissioner, and the landowner. The action may include destruction or alteration of beaver dams and removal of beaver. This subdivision does not apply to state parks, state game refuges, and federal game refuges.
If a beaver dam causes a threat to personal safety or a serious threat to damage property, and a person cannot obtain consent under subdivision 1, a person may petition the district court for relief. The court may order the commissioner to take action to reduce the threat.
