Moses Lake, Washington, in Grant County, has about 27,000 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 Prosecuting Attorney files charges, a case in the Grant County Superior Court. 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 Moses Lake
The FBI lists Moses Lake with an arrest reporting agency of its own, filed as Moses Lake Police Department. It reported 1,012 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 Grant County Sheriff's Office is the county agency. It reported 576 arrests for 2025.
How Many Arrests Moses Lake Reports
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.
- Moses Lake: 1,012 for 2025, 1,220 for 2024, 1,184 for 2023, 945 for 2022, 945 for 2021 and 837 for 2020.
Moses Lake's 1,012 arrests in 2025 were down 17 percent from 1,220 in 2024.
Through July 2026, Moses Lake reported 606 arrests, against 594 in the same months of 2025.
Across Grant County, the eight agencies with all twelve months of 2024 on file reported 2,216 arrests between them.
Booking: Where People Arrested in Moses Lake Are Held
A person kept in custody after an arrest in Moses Lake 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 2021 the jail held about 96 people, down from about 190 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 185 beds, and it ran at 104 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
SearchSystems opened and checked the custody page of the Grant County Sheriff's Office at grantcountywa.gov/1538/Jail-Inmate-Roster (page title: Jail Inmate Roster | Grant County, WA), which answered when SearchSystems opened it on September 23, 2026.
That page is the place to look for someone who was booked recently; a person cited and released at the scene, or held only a few hours by a city department, will not be on it.
A person sentenced to prison serves the sentence in a facility of the Washington State Department of Corrections, whose inmate locator is at doc.wa.gov/records/incarcerated-data-search/incarcerated-search.

That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
