Multnomah County Records Inventory
Water Rights Records
Series documents the authorization by the state and local governments for the use of public waters. Series includes water rights, licenses, and certificates of water rights issued by the state and filed with the county. Records may include alphabetical indexes to the certificates, transcripts, statements, evidence, and other records specifically related to water rights cases heard by circuit and appellate courts. Information includes names of individuals proving water rights; locations of water rights including the township, range, and section number; descriptions of land under such rights; and limitations of appropriations of rights and use of rights (i.e., length of time, usage). Original water rights certificates are filed with the Oregon Water Resources Department.
Before 1914 water rights were recorded in the Deed Record (Deeds and Indexes). Beginning in 1964 water rights were recorded in the Book of Records (Clerk and Recorder Official Filings). A separate water rights index was maintained until 1974, when it was incorporated in the Book of Records index.
