Oregon Revised Statutes Water Resources: Irrigation, Drainage, Flood Control, Reclamation § 548.010

Whenever any drainage or irrigation district has acquired any lands, by gift, purchase, eminent domain or otherwise, for the uses and purposes of the district, and thereafter by reason of a change of its plans or for any other reason determines that all or any part thereof is no longer necessary for the uses or purposes for which it was acquired, the district may sell or dispose of the lands or any part thereof, either at private or public sale. The officers of the district otherwise authorized to execute conveyances have authority to make such conveyance.
