Oregon Revised Statutes Water Resources: Irrigation, Drainage, Flood Control, Reclamation § 543A.305

(1) As used in this section:

(2) An in-stream water right shall be subject to the limitations of ORS 537.350 and shall be maintained in perpetuity, in trust for the people of the State of Oregon. The priority date of the in-stream water right shall be the same as that of the converted hydroelectric water right. The location of the in-stream water right shall be the same as the point of diversion identified in the hydroelectric water right.

(3) Five years after the use of water under a hydroelectric water right ceases, or upon expiration of a hydroelectric water right not otherwise extended or reauthorized, or at any time earlier with the written consent of the holder of the hydroelectric water right, up to the full amount of the water right associated with the hydroelectric project shall be converted to an in-stream water right, upon a finding by the Water Resources Director that the conversion will not result in injury to other existing water rights. In making the evaluation, the director shall consider the actual use of the hydroelectric project and the resulting impacts on actual use by other existing water rights as of October 23, 1999. The director may include mitigation measures as conditions of the in-stream water right to avoid injury and to ensure the continuation of authorized water uses by other existing water rights.

(4) If the hydroelectric project is authorized by a pre-1909 unadjudicated claim of registration, the determination of injury shall be based upon an evaluation of the actual use as measured during the five years preceding the conversion action, and shall not constitute a determination under ORS 537.670 to 537.695 as to the underlying claim of registration of the pre-1909 use. Judicial review of a final order relating to such a conversion shall be limited to review of the conversion action.

(5) This section shall not apply to projects on boundary waters that operate with water rights issued by the State of Oregon and by any other state except upon the written request of the water right holder.

(6) If hydroelectric production is not the sole beneficial use authorized by a water right, this section shall apply only to conversion of that portion of the water right used exclusively for hydroelectric purposes.

(7) This section shall not apply if the holder, at any time prior to conversion under subsection (3) of this section, transfers the hydroelectric water right under ORS 540.520 and 540.530, except that if a time-limited hydroelectric water right is transferred under ORS 540.520 and 540.530, the provisions of this section shall apply at the time of expiration of the time-limited water right.
