Eureka, California, in Humboldt County, has about 25,000 residents (2024 Census Bureau estimate), and its arrests are reported to the FBI by an agency of its own. An arrest in the city 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 Superior Court of California, County of Humboldt. This guide says who keeps each one, what it costs and who may see it, with the arrest counts the agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies and common questions.

Who Makes Arrests in Eureka
The FBI lists Eureka with an arrest reporting agency of its own, filed as Eureka Police Department. It reported 1,770 arrests for 2025. A city is listed separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
Outside the city, the Humboldt County Sheriff's Office is the county agency. It reported 1,843 arrests for 2025.
The FBI's agency list also places these agencies in Humboldt County: California State Polytechnic University at Humboldt (campus police); Union Pacific Railroad in Humboldt County (other); California State Parks at North Coast Redwoods and California Department of Forestry and Fire Protection at Humboldt (state agency); the Highway Patrol's Humboldt and Garberville Area Offices (state police).
How Many Arrests Eureka Reports

Booking: Where People Arrested in Eureka Are Held
The county jail is where a person arrested in Eureka and kept in custody ends up, whichever agency made the arrest, though a city department may hold someone in its own cells first and a person cited and released at the scene is never booked. The jail's record of each person held, with the charges, is a public record of the arrest, and once the person is released or sentenced the record continues in the court file.
On an average day in 2025 the jail held about 320 people, down from about 400 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 418 beds, and it ran at 95 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 Eureka
For Eureka the place to look is the case index of the Superior Court of California, County of Humboldt, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at humboldt.courts.ca.gov/case-record-request-form).
California does not let the public search another person's statewide criminal history. The record kept by the California Department of Justice goes to the person it belongs to and to employers and agencies the law authorizes; for everyone else the court's own case index is the public record of an arrest that led to a charge.
Getting a Copy of an Arrest Record in Eureka
An arrest report belongs to the agency whose officer wrote it, and that agency releases it, not the court or the jail. Under the California Public Records Act the agency must answer within 10 days, with up to 14 more days in unusual circumstances, and it may charge the direct cost of copying only, not staff time.
