The Entiat River is a tributary of the Columbia River, joining the Columbia near Entiat. The United States Geological Survey (USGS) lists two variant names for the Entiat River: En-ti-at-kwa River and Entiatqua River. The river's name is derived from the Columbia-Moses (Salishan) term /nt'yátkw/ [nt'iátkw], meaning "place of grassy water"; another source states that it was called Enteatqua which means "Rapid Water" or "Rushing Water." The name, spelled "Entiat", was selected for the river in 1958 by the Chelan County Public Utility District.The Entiat River is located entirely within Chelan County, in Washington state in the United States. Over 90% of the drainage basin of the Entiat River and its tributaries is publicly owned property, mostly the Wenatchee National Forest. A large number of place names in the Entiat River basin were given by Albert H. Sylvester.
