ORS § 548.320
The contract may provide for a lien docket which shall be furnished by the district to the county clerk of each county in which lands of the district are situated, and in which shall be set forth a description of the lands within the district and liable under such bonds, described under the present individual ownership by metes and bounds or by calls or by reference to recorded deeds, together with the total amount of refunding bonds charged against each parcel of land, the amount of annual payments thereof, the date of such payment and the rate of interest. This charge shall remain a lien on such tract or parcel of land in favor of the district and shall have priority over all other liens and encumbrances except the lien of state, county and municipal taxes. If the contract does not provide for a lien docket nothing in this section shall be construed to prevent an irrigation or drainage district from providing a lien docket as prescribed by law. In case any lands located within an irrigation or drainage district are sold for taxes such sale shall not operate to extinguish any lien appearing on the lien docket and payable at a future time.
