Graham's Mill was one of the earliest businesses in the Chillicothe vicinity, grinding cracked grains for local needs in the 1860s. Operated by a water wheel on the Thompson River, the mill produced bakers' flour as well as feed for livestock. Water power fell out of use in the late 1800s, Graham's Mill ceased operation by 1910, and it was torn down in the 1940s. The covered bridge collapsed in 1944.
