Finding Someone in Custody in Lake County
A person kept in custody after an arrest in Lake County is held at the county jail, run by the Lake County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Lake County Sheriff's Office at lakecountyor.org/government/sheriff.php (page title: Lake County Sheriff's Office), phone (541) 947-6027, which answered when SearchSystems opened it on October 4, 2026.
That page is the office's jail information page rather than a roster, so a search for a particular person goes through the office at (541) 947-6027.
