ImageThe Issue: Baseflows in the tributary streams in the western portion of Kittitas County are important in the late summer and fall when demands on these streams peak. An ongoing USGS Yakima River basin study indicates that groundwater and surface water are interconnected, however the hydrogeologic framework and the potential impacts of groundwater withdrawals on tributary streamflow in the bedrock system are not well understood.

How the USGS will help: The USGS is conducting a major study of the western Kittitas County groundwater-flow system to provide current, complete scientific information for making good decisions about managing this important resource.
