(Waupun) The state’s Department of Corrections is planning to close a cell hall at Waupun Correctional Institution. The move is expected to decrease the institution’s population by approximately 20-percent. Around 220 inmates being moved from the maximum security prison, are classified as medium-security and will be moved to various other medium-security DOC prisons across the state over the next few months. Transfers are already underway and are expected to continue through February. The move also helps alleviate long-standing staff vacancy issues at the facility. The proposed decrease in the prison population will lower the number of direct staffed posts by eight per-day, and eliminate daily relief positions needed for the cell hall.
