Information About the McNaughton Correctional Center

McNaughton Correctional Center (MCC) is located just west of the Town of Lake Tomahawk, on State Forest Road D, in Oneida County. The center is made up of seven buildings and is located on a 60-acre parcel on Little Tomahawk Lake. The center is part of the Wisconsin Correctional Center System, an "institution" comprised of 14 adult, male correctional centers and overseen by a single warden, whose office is centrally located in Madison.

The original facility was built in 1931 as a state correctional forestry camp, receiving inmates transferred from the Green Bay Reformatory.  When the Lake Tomahawk Tuberculosis Rehabilitation Camp closed in 1957, its buildings and grounds were deeded to the Department of Corrections and MCC was relocated to the camp.Today, some of the original camp structures that were built in 1910 are on the National Register of Historic Buildings.

Programs offered at MCC
Onsite Work Programs
MCC is a minimum security facility designed to help prepare the inmate for reintegration into the community through educational programing, vocational skills training, and off site work opportunities. The programs provided at MCC are developed to promote a positive work ethic and establish positive behavioral habits the inmate can utilize upon their release.  All MCC inmates are given full-time work assignments that support center operations.
