distribution); and, water reclamation and reuse. Mitigation must show that withdrawal will not impair
senior water rights, including instream flows. Mitigation strategie s may include: purchasing and
retiring an active water right; pumping water into the stream from a location that will not impact
senior water rights and instream flows; water conservation; returning stored water to the stream in the
summer; and, establishing a water trust or banking / leasing system.
If instream flow studies indicate that there is no water available for further appropriation, then the
Planning Unit agrees that more detailed water availability studies and/or a mitigation framework
would be needed in order to support future water appropriation.
These concepts are presented schematically in Figure 4-9. Ecology’s guidance on setting instream
flows and allocating water for future out-of-stream uses provides additional information (Appendix
F4).
