Statewide Inmate Family Council Message:

Local Inmate Family Councils (IFC's) are a gathering of family and friends of the incarcerated who meet regularly with Wardens to support visiting since keeping strong family connections with loved ones is a powerful rehabilitative tool. These IFC's promote visiting by clarifying rules and regulations as well as discussing health, education, vocational training, packages, books, and related issues. For more information on connecting with a local IFC, please visit the Statewide IFC website.

About High Desert State Prison

The primary mission of High Desert State Prison (HDSP) is to provide for the Housing and Programming of general population and sensitive needs high security (Level IV) and medium security (level III) inmates. Our inmate population consists of three (3) Level IV yards, two (2) of which are 180 design buildings (Facility C and Facility D), and one (1) 270 design building (Facility B). Our 270 design yard, Facility B, was converted to a Sensitive Needs Yard (SNY) in October 2007, which houses Level IV SNY inmates. On our 270 design medium Level III, Facility A houses Level III inmates. Facility A is also the home of our Reentry Hub Facility, which provides relevant training and services to eligible and interested inmates in order to facilitate the successful transition back to their communities and reduce their likelihood of reoffending. HDSP’s Reentry programs are comprised of Academics, the California Identification Card Program, Pre-Employment Transition, and Cognitive Behavioral Treatment, which includes Substance Abuse Treatment, Anger Management, Family Relationships and Criminal Thinking. The Minimum Support Facility (MSF) houses non camp eligible Level I inmates who perform job duties in various areas of the institution outside the secure perimeter, such as the warehouse, garage, out grounds, staff snack bar, etc. Our Administrative Segregation Unit (ASU) is located on our Facility D, 180 design housing and consists of two buildings, D7 and D8. Within the first three years of HDSP’s activation, it became apparent that the building originally designed and designated as the ASU was not adequate to meet the demands of the inmate population who require segregated housing. Construction on a new stand-alone ASU began in October 2001. The unit was named Facility Z and activated in September 2004. HDSP houses inmates with the lowest level custody, Minimum B, all the way up to Maximum custody (ASU inmates). Design capacity for the entire institution is approximately 3,660 inmates.

Historical Notes

In early 1990, the CDC initiated discussions for a new prison in Lassen County on the grounds of the California Correctional Center (CCC). This location took advantage of existing state property and the ability to share operations with an existing prison.

Construction of the new prison began on July 14, 1993, with a budget of $240 million. In just 24 months the new prison became a dominant part of the surrounding landscape. The construction of the prison consumed 71,985 yards of concrete, 20,000 tons of steel, 364 miles of electrical wire and 7 miles of chain link fencing, combined with the multitude of other required construction materials necessary in the completion of this modern prison complex.

Named High Desert State Prison by the Lassen County Board of Supervisors, the prison is located approximately eight miles east of the town of Susanville, or about a 1 hour 30 minute drive northwest of Reno, Nevada.
