Reviewed and updated October 9, 2026 by the SearchSystems.net editorial team. The arrest counts are the ones each agency reported to the FBI, as the FBI held them on October 8, 2026. The jail figures are from the Vera Institute of Justice's Incarceration Trends data. Every office link was opened and checked against the office's own site on September 24, 2026.
Benton County, Oregon, has about 99,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Benton County Sheriff's Office, two city agencies and three 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 Benton 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.

Who Makes Arrests in Benton County
The Benton County Sheriff's Office is the county agency that reports arrests to the FBI for Benton County. It reported 510 arrests for 2025.
The FBI lists two cities in Benton County with a reporting agency of their own, with the Census population and what each reported:
- Corvallis, 61,993 residents: 1,748 arrests reported for 2025.
- Philomath, 5,795 residents: 88 arrests reported for 2025.
A city on that list is reported separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
The Albany Police Department is listed by the FBI across two counties including Benton County, so its arrests are not broken out for Benton County here.
The FBI's agency list also places these agencies in Benton County: Oregon State University (campus police); the Benton County Liquor Commission (state agency); the Benton County State Police (state police).
How Many Arrests Each Agency Reports in Benton County
The FBI publishes every agency's monthly arrest counts on the Crime Data Explorer. These are the full-year totals, all offenses, as the FBI held them on October 8, 2026; a year with months missing or not reported is left out.
- Corvallis: 1,748 for 2025, 1,799 for 2024, 1,766 for 2023, 1,676 for 2022, 1,674 for 2021 and 1,370 for 2019; 2020 is missing months.
- Benton County Sheriff's Office: 510 for 2025, 536 for 2024, 485 for 2023, 410 for 2022, 434 for 2021 and 529 for 2019; 2020 is missing months.

Together, the three agencies with all twelve months of 2025 on file reported 2,346 arrests that year. The same agencies with both 2025 and 2024 complete reported 2,346 in 2025 against 2,420 in 2024, down 3.1 percent.
Through June 2026, the three agencies with every month so far on file reported 1,092 arrests, against 1,195 in the same months of 2025.
Booking: Where People Arrested in Benton County Are Held
A person kept in custody after an arrest in Benton 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 46 people, up from about 33 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 40 beds, and it ran at 82 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 Benton County
Whether someone was arrested in Benton County, and what came of it, shows up in two places: the case index of the Benton 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/benton/records/pages/access.aspx); the District Attorney, which decides whether an arrest becomes a charge (its page is at da.bentoncountyor.gov/district-attorney-ryanjoslin).
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 Benton County
The report of an arrest is released by the agency that made it; the jail and the court hold their own records of the same event, but not the report. 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.
- An arrest by the Benton County Sheriff's Office: ask its records unit.
- An arrest in Corvallis or Philomath: the records unit of the agency that reports for that city; the city guides linked above name each city's records office.
- An arrest by Oregon State University, the Benton County Liquor Commission or the Benton County State Police: the records office of the agency involved.
- A defendant who has been charged gets the report through the case: the District Attorney handles discovery for pending cases.
- The court file of a case that was filed: the Benton County Circuit Court, through the court records page at courts.oregon.gov.
- Any county record that is not posted: the county records request page SearchSystems verified is at counsel.bentoncountyor.gov (page title: Accessing Public Records from Benton County | Benton County Counsel, Oregon).
- Your own statewide record: the same request described above, for your own name.
