Male Medium and Minimum Security - Opened 1909
- Overview
- Visitation/Mail
Oklahoma State Reformatory (OSR) was established in 1909, built by inmates using granite blocks cut from the hills nearby. It was originally built to house younger inmates who could be rehabilitated, providing them programs in which they can get an education and learn a trade. However, OSR evolved gradually over time into a full-fledged prison with minimum- and medium-security inmates.
The prison added four new housing units in 1984 and closed its “old cell house” in compliance with federal court mandates. In 2016, ODOC moved OSR’s inmates to North Fork Correctional Center, which the agency began leasing from CoreCivic. ODOC closed its inmate work centers and moved their occupants to OSR, which became community-level security.
Today, OSR, now a medium-security facility, is home to more than 800 medium-level security inmates, in addition to 200 minimum-level security inmates. The 10-acre facility has none of its original buildings, and its oldest structure dates back to 1921. A storied history includes being home to the nation’s first accredited high school in a prison and the first female warden in the United States, Clara Waters.
