Notice of Final SEPA Determination

Twin Lakes Water Storage Project, SEPA

The Twin Lakes Aquifer Coalition has applied for a groundwater right under application G4-34915 to withdraw groundwater near the Methow River to augment water levels in Twin Lakes area of Okanogan County that have been declining since 2001. TLAC will pump from wells in hydraulic continuity with the river only when river flows are high. Approximately 800 acre feet will be diverted to storage during each of the first ten years and 550 acre feet each year thereafter. The project will store about 1,600 acre feet and will return 300-450 acre feet annually to the river through the aquifer system. Although water withdrawals from the Methow River system will be limited to high flows, water returning to the river will be continuous and will be trusted to Office of Columbia River to benefit and out-of-stream uses.

The Okanogan County and Department of Ecology Office of Columbia River SEPA Co-Lead Responsible officials issued a final environmental determination of non-significance (DNS) in accordance with WAC 197-11. This decision may be appealed in accordance with OCC 14.04.220. Appeals must be made in writing to the Board of Okanogan County Commissioners, 123 5th Ave N Ste. 150, Okanogan, WA 98840. Appeals must be submitted or postmarked by 5:00 p.m. on December 26, 2013. Appeals shall state with specificity the elements of the environmental checklist and resulting determination the appellant finds objectionable and shall state the reason therefore. Appeals must include the $300.00 appeal fee. Failure to file a timely and complete appeal shall constitute waiver of all administrative appeal under county code.
