Abstract:

This study focuses on the City of Ellensburg’s proposed concept for Aquifer Storage and Recharge (ASR) in the Kittitas Valley: the recharge of Yakima River water into the Upper Ellensburg Formation via existing City-owned wells. This study includes a compilation and synthesis of readily available information regarding the feasibility of development of an ASR project. Coho recommends proceeding with an ASR pilot test to further inform the viability of an ASR program and permitting. This report contains many informative tables and figures on relevant topics such as groundwater characteristics, hydrogeologic units, and geologic units.
