The Washington Department of Transportation, Yakima County and the City of Yakima came together in 2004 with the desire to develop the Lower Naches River Coordination Partnership as a result of initiatives identified in the Upper Yakima River Comprehensive Flood Hazard Management Plan (CFHMP).
The groundwater resources of the Yakima Basin are the focus of this cooperative study between the United States Geological Survey (USGS), the Bureau of Reclamation, the Washington State Department of Ecology, and Yakama Nation.
The goal of the GWMA is to reduce nitrate contamination concentrations in groundwater below state drinking water standards. The target area extends from Union Gap to County Line Road in Yakima County, Washington, minus the Yakama Nation.
