The Graue Mill building was eventually added to the properties of the DuPage County Forest Preserve District. In 1934, it was decided to restore the mill to the period of 1852-1868, the time the waterwheel was in operation. The restoration was completed in 1943 but was not maintained. In 1950, the mill property was leased to the DuPage Graue Mill Corporation, an organization formed by local residents, who repaired the waterwheel and gear system and opened the museum.
Graue Mill was listed in the National Register of Historic Places in May 1975. And in 1981 was recognized as an Illinois Historic Mechanical Engineering Landmark by the American Society of Mechanical Engineers -- the only gristmill so designated on a national or local level, representative of an important technology and era in the history of America.
