Oregon Revised Statutes Water Resources: Irrigation, Drainage, Flood Control, Reclamation § 551.140

Any person through whose lands a dike has been constructed under this chapter may be allowed to construct a dike upon new lines between any two points on the original line. In such case the owner shall file application with the county court, giving a plat of the proposed change, and indorsed by the superintendent of the district. If the court is satisfied that the change is not detrimental to the district, the application shall be granted. The applicant shall construct the new dike at the expense of the applicant, and up to the standard of the original, of which fact the superintendent shall be the judge. The dike thus constructed shall become the property of the district in the same manner as the original, and subject to the same regulation, and the right of way of the original dike shall thereupon become vacated.
