Thompson’s Mills is a unique reminder of times past, chronicling the past 150 years of Oregon rural life. The oldest water-powered grain mill in the state, its system of waterways, dams, control gates, ditches and dikes has moved water from the Calapooia River to the mill head gates since 1858. Interpretive panels tell the story of the lives of the mill keepers and area farmers, historic water rights, and the millrace. The park is open daily.
