(b) A holder of a water right certificate that authorizes the storage of water may change the type of use identified in the water right certificate, as described in paragraph (a) of this subsection, without losing priority of the right.
(2) Subject to the limitations in ORS 537.490, any right to the use of conserved water allocated by the Water Resources Commission under ORS 537.470 may be severed from the land and transferred or sold after notice to the commission as required under ORS 537.490.

(A) The water is applied to lands which are acquired by annexation or through merger, consolidation or formation of a water authority, so long as the rate and use of water allowed in the original certificate is not exceeded;
(B) The use continues to be for municipal purposes and would not interfere with or impair prior vested water rights; or
(C) The use is authorized under a permit granted under ORS 468B.050 or 468B.053 and for which a reclaimed water registration form has been filed under ORS 537.132.

(5) The relocation of a point of diversion as necessary to follow the movements of a naturally changing stream channel does not constitute a change in point of diversion for purposes of ORS 540.520 if:
(a) The diversion point stays within 500 feet of the point of diversion on record with the Water Resources Department;
(b) The change does not move the diversion point upstream or downstream beyond the diversion point of another appropriator; and
(c) The diversion is provided with a proper fish screen, if requested by the State Department of Fish and Wildlife.
(6) In the event that government action results in or creates a reasonable expectation of a change in the surface level of a surface water source that impairs or threatens to impair access to a point of diversion authorized by a water right permit, certificate or decree, the owner of the water right may change the point of diversion or add an additional point of diversion in accordance with the provisions of this section in lieu of complying with the requirements of ORS 540.520 and 540.530. Before changing the point of diversion, the water right owner shall provide written notice of the proposed change to the Water Resources Department. Within 15 days after receipt of such notice, the department shall provide notice by publication in the department’s public notice of water right applications. Within 60 days after the department receives notice from the owner, the Water Resources Director, by order, shall approve the change unless the director finds the changes will result in injury to other existing water rights. All other terms and conditions of the water right shall remain in effect.
(7) The sale or lease of the right to the use of conserved water under ORS 537.490 does not constitute a change of use or a change in the place of use of water for purposes of ORS 540.520.
