Klamath River Basin Adjudication

Senate Bill 206 (2015)

Senate Bill 206 allows “determined claims,” being water rights determined and established in the Klamath Basin Adjudication Corrected Partial Order of Determination, to be temporarily transferred for up to five years or leased instream for up to five years.  An application shall not be approved if the determined claim has been stayed by a court judgement, if the application proposes to move the point of diversion upstream, or if its approval would cause enlargement or injury to another claim or water right. Senate Bill 206 expires January 2, 2026.


KIamath River Basin Adjudication

This adjudication is the process of determining claims to the use of surface water in the Klamath River Basin. The first phase was the review and determination of these claims by the Oregon Water Resources Department, including the hearing of contests to claims and the issuance of proposed orders by administrative law judges from the State’s Office of Administrative Hearings. This phase of the process was completed with the Department’s issuance of the Adjudicator’s Findings of Fact and Final Order of Determination on March 7, 2013.

The process is now in the second phase. This is the review of the Final Order of Determination by the courts. Adjudication claimants or contestants who dispute the Department’s determination of their claims or contests will have an opportunity to file exceptions with the Klamath County Circuit Court (Court). The Court will then review these exceptions, and will ultimately issue a water rights decree affirming or modifying the Final Order of Determination. The Department can issue water right certificates in accordance with the decree once it is issued by the Court.
