Water quality in the Central Columbia Plateau of eastern Washington and western Idaho has been adversely affected by agriculture, especially in irrigated areas, according to the results of a five-year investigation by the U. S. Geological Survey (USGS). Some improvements, however, are noticeable, such as less sediment being washed into streams. The Columbia Plateau covers more t square miles within the Columbia River Basin in Washington, Oregon, and Idaho (fig. 1). More than 10 million acres support a $5 billion per year agricultural industry, among the most productive in the Nation.

District of Columbia Water Quality Thirty-six waterbody segments were monitored for water quality in order to meet the goals of the Clean Water Act (CWA) that apply to the District. Each of the waterbodies has been assigned designated uses in the District’s water .

The Columbia Plateau ecoregion is a Level III ecoregion designated by the United States Environmental Protection Agency (EPA) encompassing approximat square miles (83, km 2) of land within the U.S. states of Washington, Oregon, and ecoregion extends across a wide swath of the Columbia River Basin from The Dalles, Oregon to Lewiston, Idaho to Okanogan, Washington near the Borders: Eastern Cascades Slopes and Foothills . The Central Columbia Plateau/Yakima River Basin (CCYK) National Water-Quality Assessment (NAWQA) study unit is located in Central Washington, USA. The study unit is dominated by intensive agricultural practices, with irrigated agriculture a common practice for crop production (see study area description). Due to the intensive.
