Adjudication proceedings have been completed for most of the major stream systems in eastern and southern Oregon and a few of the larger tributaries to the Willamette River. Nearly 100 decrees have been issued on individual streams in Oregon. Water right certificates have been issued for most of the decreed rights. An adjudication proceeding is underway in the Klamath Basin, which involves private water users, the Bureau of Reclamation, other federal agencies, and the Klamath Tribes.
Old decree records for adjudicated stream systems may be viewed through the Department’s electronic document vault.
