Welcome to the Oregon Jail Manager's Association website. OJMA is an affiliate of the Oregon State Sheriff's Association and represents the interests of jails throughout Oregon. Oregon Jails Oregon law requires the Sheriff of each county in Oregon to operate a jail to lodge adult pre-trial and sentenced offenders.
Jails do much more than simply house prisoners.
In most Oregon counties, jail staff are also responsible for inmate admissions court security, transports, rehabilitative programs, and other additional support unit work groups. Many Oregon sheriff s also run work camps, work crews, work release centers, home detention and in some counties, parole and probation services. Operating a jail is much different than operating a prison. Admission numbers tell a lot of the story. An average 200-300 bed jail in Oregon will process between 6,000 and 10,000 inmates throughout the course of a year.
