WAC 173-545-100

Agency filings affecting this section

Maximum future allocation.

  (1)(a) The department determines that there are certain times when there are surface waters above the instream flows, referred to as "high flows." These high flows provide critical ecological functions such as channel and riparian zone maintenance, flushing of sediments, and fish migration. In order to protect the frequency and duration of these higher flows, the department hereby establishes maximum amounts of water/flow that can be withdrawn from specific streams at specific times, subject to the flows in WAC 173-545-060.

     (b) A maximum allocation shall be used to review future applications for beneficial uses from the mainstem Wenatchee and tributary rivers and creeks.

     (2) The designation of a maximum allocation limit does not constitute a determination by the department that a permit to appropriate public waters will be issued. RCW 90.03.290 and 90.44.060 require that a permit can be issued only upon a determination that: Water is available; the use will not impair existing rights; water will be applied to a beneficial use; and the use is not detrimental to the public interest. Establishment of a water right within the limit of the allocation occurs after proper authorization from the department and after the water is first put to beneficial use. The water rights are subject to the instream flows established in WAC 173-545-060, and other provisions established in statutory, administrative and case law.

     (3) The department shall require the metering and reporting of all permitted surface and ground water withdrawals for which a maximum allocation applies.

     (4) The department will maintain a record of the amount of water appropriated from the Wenatchee River and tributaries specified above. Once the maximum amounts are fully appropriated, the department shall notify Chelan County and the planning unit in writing. The department shall also issue a public notice in a newspaper of general circulation for the region.
