Umatilla County, Oregon, has about 80,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Umatilla County Sheriff's Office, six city agencies and two campus, state or other agencies. An arrest leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the District Attorney files charges, a case in the Umatilla County Circuit Court. This guide says who keeps each one, what it costs and who may see it, with the arrest counts each agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies, cities and common questions.

Booking: Where People Arrested in Umatilla County Are Held
A person kept in custody after an arrest in Umatilla County is held at the county jail, whichever agency made the arrest, apart from the short stay some city departments' own holding cells allow; a person cited and released at the scene is not booked at all. The jail's record of each person held, with the charges, is a public record of the arrest, and the court file takes over from there.
On an average day in 2023 the jail held about 120 people, down from about 180 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 174 beds, and it ran at 105 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.

How to Find Out About an Arrest in Umatilla County
Whether someone was arrested in Umatilla County, and what came of it, shows up in two places: the case index of the Umatilla County Circuit Court, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at courts.oregon.gov/courts/umatilla/records/pages/default.aspx); the District Attorney, which decides whether an arrest becomes a charge (its page is at co.umatilla.or.us/departments/district-attorney, phone 541-278-6270).
Statewide, Oregon eCourt Case Information is the Oregon Judicial Department's online case search, free for basic case information.
Oregon is one of the states that lets anyone look up another person's statewide criminal history: an Open Record Request returns anyone's Oregon conviction record by name, and the subject is told who asked, for $10 a search, through the Oregon State Police. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
Getting a Copy of an Arrest Record in Umatilla County
An arrest report belongs to the agency whose officer wrote it, and that agency releases it, not the court or the jail. Under the Oregon Public Records Law the agency must answer within 15 business days where practicable, after acknowledging the request within 5, and it may charge the actual cost of making the record available.
