Section 173-527-100. Future appropriations for interruptible use.

(1) Ecology finds there may be water available above existing water rights and instream flows, which may be captured for interruptible use. This water is only available from November 16 to May 14 and may only be withdrawn from the Kalama, North Fork Lewis (below Merwin Dam), and East Fork Lewis rivers.

(2) Prior to commencement, the person or entity seeking a new interruptible appropriation must demonstrate a seasonal need and provide assurances that any effects on surface water that may result from withdrawals will be limited to the above time period and locations.

(3) Ecology shall deny an appropriation for interruptible use if such use, or the cumulative effects of such uses, would compromise habitat-forming functions provided by high flows. In no case shall new individual or cumulative allocations exceed the values indicated in Table IV as specified for each river. However, these allocation limits may be lowered on a case-by-case basis whenever more protection of habitat-forming functions is needed.

(4) Interruptible uses are subject to existing water rights and instream flows set in WAC 173-527-060.
