WRIA 30 Multipurpose Water Storage Assessment: Little Klickitat River and Swale Creek

Like other parts of Washington State, water is not uniformly available throughout the year in the Klickitat River watershed (WRIA 30), which can create conflicts between water demands for fish versus people. Aspect completed the initial assessment of storage options for developing new agricultural and municipal water supplies within two priority subbasins of WRIA 30: Little Klickitat River and Swale Creek. We identified prospective storage options based on each subbasin’s physical characteristics, irrespective of water needs. From our assessment, the implementing agencies have initiated a more detailed feasibility study for one of the identified options, in-channel storage within Dry and Idlewild Creeks to achieve both instream and out-of-stream benefits, which Aspect is conducting.
