Thompson's Mills State Heritage Site

Thompson's Mills is a unique survivor of times past, chronicling 160 years of Oregon rural life and honoring the owners who continually adapted the mill to the changing world around it.

It is the oldest standing water-powered grain mill in Oregon, and its turbines can be seen in action on guided tours.

A water right that predates statehood produces the water flow that still runs the milling machines for demonstrations today.

and 3 p. m. and Friday-Sunday on demand 9 a. m. -4 p. m. The mill address is 32655 Boston Mill Drive, Shedd, OR 97377.

In May 2004, OPRD purchased the property from the last private owner for $856,547 and paid an additional $15,000 for artifacts and historic equipment associated with the mill. After 3 years of safety and structural upgrades Thompson's Mills State Heritage Site opened to the public. Work continues every day at the Mill- from minor repairs to major rehab or waterworks projects. An adjustable dam was installed in 2013 allowing the Mill to have a full mill race and demonstrate milling year round while also allowing for fish passage and drainage after winter rains. The removal of Sodom Dam, the removal of Shearer Dam and finally the construction of the adjustable dam allow the Calapooia River to be free-flowing yet the function and appearance at Thompson's Mills is preserved for you to experience.
