(3) The instream flows in subsection (1) of this section shall retain their original priority date and quantities, except where the flows in WAC 173-545-060 (7) are lower than the flows in subsection (1) of this section. In those instances, existing water rights subject to subsection (1) of this section will instead be subject to the lower flow in WAC 173-545-060 (7). However, the priority date of the original right remains unchanged. If, at a future date, it is determined that the higher flows in subsection (1) of this section are required to retain flows necessary to preserve fish, wildlife, scenic, aesthetic, or other environmental values, the department will issue an order notifying the holders of the conditioned permits and certificates of such a decision and the justification.
