WAC 173-517-140

Maximum future allocations for interruptible use.

(1) Ecology finds there may be water available in excess of instream flows at certain times of year, which may be appropriated for interruptible uses. This water is only available from the Big Quilcene River from November 16 to June 15 and from Chimacum Creek from December 1 to February 29.
(2) A person or entity seeking a new interruptible appropriation must provide assurances that any negative effects on surface water that may result from withdrawals will be limited to the above locations and times.
(3) In no case shall total cumulative appropriations exceed the allocation limit specified in Table 7 for each river. However, ecology may lower these allocation limits on a case-by-case basis, upon consultation with the state department of fish and wildlife and tribes, whenever more protection of habitat-forming functions is needed.
(4) Interruptible uses must not impair existing water rights and instream flows set in WAC 173-517-090.
