Columbia County Jail Roster
The Columbia County jail roster is the public log of people booked into the small county jail in Dayton. Columbia County is one of the least populated counties in Washington, so the jail is smaller than most. You can still search for an inmate by contacting the sheriff's office directly. The roster tracks each booking, each charge, and each release date. This page explains how to look up the Columbia County jail roster, what records you can get, and what state law says about public access to jail data in this part of southeastern Washington.
Columbia County Jail Roster Overview
Searching the Columbia County Jail Roster
Columbia County does not run a large online inmate search tool like some bigger counties do. The best way to search the Columbia County jail roster is to call the Columbia County Sheriff's Office directly. Ask for the records desk and give them the full name of the person you want to find. The staff can check the roster and tell you if the person is in custody, what the charges are, and what the bail has been set at.
You can also visit the sheriff's office in Dayton during business hours. Walk in and ask to see the jail register. Under state law, the jail register must be open to public inspection. That means the sheriff cannot turn you away. The register lists each person held, the booking date and time, the cause of the booking, and the release info. It is not fancy, but it is the official record.
If you want to track a Columbia County inmate over time, use the VINE service. VINE sends free alerts when an inmate is released or moved. It covers Columbia County and every other county in Washington.
Columbia County Jail Roster Records
Under RCW 70.48.100, the Columbia County jail must keep a register that is open to the public. The law says the jail must log the name of each person held, the hour and date of the booking, the cause of the booking, and the hour, date, and manner of release. That is the core of the Columbia County jail roster. The full inmate file goes deeper, but only the register part is public by default.
The jail is smaller here than in most Washington counties. Columbia County is one of the smallest by population, so the number of bookings in any given week is low. That said, the same state rules apply. The register is public. The rest of the inmate file is kept in confidence and may only be shared with criminal justice agencies, the courts, or with the written consent of the person.
Public Records Requests in Columbia County
The Public Records Act gives you the right to ask for jail records from the Columbia County Sheriff's Office. You do not need to give a reason. The county must respond within five business days. Direct your request to the Columbia County public records office or to the sheriff's office in Dayton.
Put the inmate name and the date range in your request. If you have a booking number, include that too. The basic roster data is free to view, but copies of documents may carry a per-page fee. Medical records, mental health records, and security plans are exempt from disclosure under state law.
Note: Columbia County must reply to your records request within five business days under the Public Records Act.
Columbia County Jail Roster Laws
Two laws control what you can see. The first is RCW 70.48.100. It says the jail must log each booking and each release and keep that log open to the public. The second is RCW 42.56, the Public Records Act. Together, they give you a strong right to see the Columbia County jail roster without giving a reason.
The Department of Corrections was created under RCW 72.09. If a person moves from the Columbia County jail to a state prison after sentencing, use the DOC Incarcerated Search to find them. The DOC search shows the name, age, DOC number, and current state facility.
Court Records in Columbia County
People booked into the Columbia County jail often have a case in Columbia County Superior Court. The court handles felony cases and larger civil matters. Court calendars and case info are available through the court office in Dayton. You can also search Washington court cases through the Odyssey portal, which covers district and municipal courts statewide.
Pair the court record with the jail roster data to get a full picture. The roster tells you the booking date and charges. The court record tells you the next hearing, the judge, and the attorney of record. For a statewide criminal history, use the WATCH service from the Washington State Patrol.

Columbia County Jail Roster Access Tips
Columbia County is small. The jail in Dayton does not see the volume of bookings that a place like King County or Spokane County does. That can work in your favor when you need info fast. A phone call to the sheriff's office can get you an answer in minutes. The staff know who is in the jail because the numbers are low. Walk-in requests at the office in Dayton are also handled quickly most of the time.
If you need records from the past, put your request in writing. Old jail roster entries are kept by the sheriff's office and can be pulled with a public records request. State law does not put a time limit on how far back you can ask. The five-day response rule still applies. For urgent matters, explain that in the request and the office may be able to speed things up.
