Mule Creek State Prison (MCSP) is a California State Prison. It was opened in June 1987 and covers 866 acres (350 ha) located in Ione, California. The current population is 3,065 or 180.3 percent of its designed capacity of 1,700. The prison has a staff of 1,242 and an annual operating budget of $157 million.
In 2005, MCSP became the only California state prison exclusively for Sensitive Needs Yards (SNY) inmates. SNY inmates are segregated from mainline (a.k.a. general population) inmates for their own safety. Many are gang dropouts, informants, sex offenders, and former law enforcement officers.
