The Osage Mills Dam is a historic dam in rural Benton County, Arkansas. It impounds Little Osage Creek, just upstream of Mill Dam Road, between Rogers and the Northwest Arkansas Regional Airport. The dam was built c. 1890 out of coursed stone with a rusticated face. It was built to provide power to a grist mill that served the area, of which only a small portion of the millrace remains visible. The dam is the only known structure of its type in the county.
