Founded in 1980

The Entiat Museum building was built in 1895 by the Entiat Improvement Company as headquarters and a home for their ranch manager. The ranch was a large hay and cattle ranch.  The Entiat Improvement Company was the major commercial center at that time.  The Museum is situated on a knoll at the north end of the Entiat City Park.  It has been renovated many times through the years, but has always been at the present site; even when steamboats ran the rapids and Chief Chilkosahaskt of the Entiat Tribe lived at the mouth of the Entiat River.
