Goldendale Aquifer Storage Recovery (ASR) Feasibility Study

The City of Goldendale’s Simcoe Springs is a snowmelt-derived source of exceptional-quality water; the source is already insufficient to meet the community’s growing demands year-round, and may be reduced in quantity during summer months by future climate change. Aspect helped the City assess expanded use of the critical supply source—storing surplus winter spring flows in an aquifer and pumping the water back for use in the summer (ASR). Our ASR feasibility study developed the information required for an ASR permit application as specified in Chapter 173-157 WAC. Based on our recommendations, the City applied for a new seasonal water right to divert additional Simcoe Springs water for ASR.
