Oregon Revised Statutes Water Resources: Irrigation, Drainage, Flood Control, Reclamation § 549.160

The commissioners, or a majority of them, shall make a report to the county court at the next regular session thereof, stating the location of the ditch or other work contemplated, the name of the person entitled to damage, and the amount, if any is assessed. If the county court is satisfied that the report is just, and after payment by the applicant for the right of way of all costs of locating such ditch or other work, and the damages, if any are assessed, the court shall cause the same to be recorded. The applicant then may proceed to make such ditch, or do such work of straightening the stream or building up or straightening the banks thereof, doing as little damage to the land it passes through as possible.
