Klemme's age and a shift in the local economy from farming to mining brought about the shutdown of the mill in 1956. He continued to operate the lodge until the 1960s. In 1975, the foundation leased the mill and surrounding property to the Missouri Department of Natural Resources to operate as a state historic site. Also on the property is a building that once housed a general store owned by Adam Wilhite. Today, the restored mill contains most of its original machinery.
Visitors can see the remaining machinery come to life during a tour of the mill.
With the turn of a wheel, the mill begins to operate as it did years ago, grinding grain into flour. The sound of the water gushing over the dam outside the mill is replaced with the sounds of the belts and rollers turning. Tours of the mill are given year-round, although days and times vary by season. Groups should make advance reservations by contacting the site office. Benches along the trail allow visitors to catch their breath or just sit and enjoy the sights and sounds of nature.
