The Columbia County Inmate Population
The modern Columbia County inmate population is not held in a Columbia County jail building. The Columbia County Sheriff's Office says the local jail closed in March 2023 and that inmates are transported to Walla Walla County Corrections. That change is the first fact to check before reading any count, roster result, or jail record. Columbia County still has the arresting sheriff, courts, clerk, and prosecutor in Dayton, but jail custody is handled at the regional facility in Walla Walla.
For public data, the serving facility is Walla Walla County Corrections Department. Its public roster can show Columbia County bookings because an inspected current inmate detail listed "Booking Origin: Columbia County Sheriff's Office." Columbia-only daily population, Columbia-only admissions, and Columbia-only demographic totals were not located in public WASPC data. The useful public count is therefore the Walla Walla facility count, paired with a clear note that Columbia detainees are only part of that larger jail population.
Columbia County Inmate Population Statistics
The most current sourced numbers come from the WASPC 2024 Washington State Jail Statistics row for Walla Walla County Corrections Department. That row reports the jail that now serves Columbia County arrests, not a separate Columbia County jail census. The older Columbia County row from WASPC 2021 is useful only as pre-closure context. It showed a small local jail before the March 2023 closure, while the 2024 public operating numbers belong to Walla Walla.
| Measure | Figure | Source / Year |
|---|---|---|
| Columbia County jail operating status | Closed, inmates housed at Walla Walla | Columbia County Sheriff page, inspected 2026 |
| Serving facility beds | 120 beds | WASPC 2024 jail statistics |
| Serving facility average daily population | 69.67 ADP | WASPC 2024 jail statistics |
| Average length of stay | 13 days | WASPC 2024 jail statistics |
| Total admissions | 2,182 | WASPC 2024 jail statistics |
| Former Columbia jail capacity | 10 design beds | WASPC 2021 Columbia County row |
Columbia County Inmate Population Trends
The trend is a facility transition more than a simple rise or fall. WASPC 2021 still showed Columbia County with its own small jail row. By 2023, the sheriff reported that the Columbia County jail had closed. By 2024, the best public operating figures for local custody came from the Walla Walla facility row. That makes the Columbia County inmate population harder to read from a single spreadsheet because the current public count is a shared regional facility count.
| Year | Facility / Scope | Published Count | How to Read It |
|---|---|---|---|
| 2021 | Columbia County jail | 4 ADP; 10 design beds | Pre-closure local jail row. |
| 2023 | Columbia County jail | Closed as of March 2023 | Sheriff notice changed the lookup path. |
| 2024 | Walla Walla County Corrections | 69.67 ADP; 120 beds | Serving facility total, not Columbia-only. |
| 2026 inspection | Walla Walla Inmate Inquiry | Current roster records visible | Detail can show Columbia County booking origin. |
Who Makes Up Columbia County Inmates
WASPC publishes demographic figures for Walla Walla County Corrections, the serving facility. It does not break out Columbia-origin detainees in the public row. In 2024, the Walla Walla row showed male ADP of 60.75, female ADP of 8.42, and unknown gender ADP of 0.67. Race entries included 49.67 White ADP, 3.58 Black ADP, 0.58 American Indian or Alaska Native ADP, and 15.75 unknown race ADP. Those are facility-level numbers.
The roster side shows operational categories instead of a census report. Public inmate details can list prisoner type, booking origin, bond or bail totals, charge rows, and whether the person remains in custody. Columbia County booking origin matters because the Walla Walla roster is broader than Columbia County. A person can be in the same facility for Walla Walla, College Place, Walla Walla County, or Columbia County reasons.
Columbia County Jail Capacity
Current pages should not call 120 beds the Columbia County jail capacity. The 120 beds belong to Walla Walla County Corrections Department. Columbia County's former pre-closure row listed 10 design beds in WASPC 2021, with 4 ADP and a 30-day average length of stay. The current custody path is a contract or regional housing arrangement, supported in state law by RCW 70.48.090, which allows local governments to contract for jail services.
WASPC 2024 also listed electronic monitoring and work release as Walla Walla programs and marked in-custody deaths as "Yes" for the facility row. The extracted public data did not give Columbia-only detail, a pod breakdown, or public overcrowding findings. The safer reading is narrow: Walla Walla is the serving jail, it had 120 beds and 69.67 ADP in 2024, and Columbia County detainees are included only when booked or held there.
Laws Governing Columbia County Inmates
Washington law sets the public-record and jail-operation framework behind the Columbia County inmate population. The Public Records Act is the main access law for identifiable nonexempt records. The City and County Jails Act governs local jail services, including contract housing, work release, and medical care. Criminal-history privacy rules also matter because a booking record, a court charge, and a criminal-history report are different records with different limits.
Key statutes:
RCW 42.56 sets Washington's public-records framework for state and local agencies.
RCW 42.56.080 requires requests for identifiable records, such as a booking number or named booking photo.
RCW 70.48 governs city and county jail operations, including local custody authority.
RCW 10.97 controls criminal-history information and limits on dissemination.
Search Columbia County Inmate Population
For a current local arrest, start with the Walla Walla Inmate Inquiry. The Columbia County sheriff links readers to Walla Walla Corrections after the local jail closure. The roster covers current and historical bookings in that system, so it is broader than Columbia County. Use the in-custody filter when the goal is current jail custody.
- Open the Walla Walla Inmate Inquiry linked from the Columbia County Sheriff page.
- Check In Custody for a current Columbia County inmate population search.
- Enter a name, subject number, booking number, or booking date range if known.
- Leave Housing Facility blank unless Walla Walla County Corrections Department is needed as a filter.
- Open the name result and review booking origin, charges, bond, and custody status.
- If the person was sentenced to prison, use the Washington DOC incarcerated search instead.
Current Columbia County Inmate Lookup
The roster has several search paths. A blank or broad search can return many historic records, so the current-custody box is important. Results show name, subject number, in-custody status, multiple-bookings status, and housing facility. A detail page can then show booking history and charge tables. The public page did not publish a refresh interval, so the phone line is still part of the access chain when a new arrest is not visible.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Name | Text | Unspecified | Use last name first, then broaden spelling if needed. |
| Subject Number | Text | No | Person-level numeric identifier. |
| Booking Number | Text | No | Observed format uses year plus sequence number. |
| In Custody | Checkbox | No | Limits results to people currently jailed. |
| Booking From / To | Date fields | No | Useful when the arrest date is known. |
| Housing Facility | Dropdown | No | Walla Walla County Corrections Department was the public option inspected. |
The current in-custody roster filter is the fastest way to separate active jail population records from old bookings. If no result appears, call Walla Walla Corrections at 509-524-5430 for inmate information or contact Columbia County Sheriff records staff for local arrest-record routing.
Columbia County Inmate Record Fields
Public detail pages in the Walla Walla system can carry both Columbia County and jail-custody facts. The sample current Columbia-origin profile showed the booking origin field, bond data, booking history, and charge rows. It did not show a mugshot, date of birth, race, internal housing pod, court date, judge, or projected release date on the inspected public page.
| Field | What It Shows |
|---|---|
| Name and subject number | Public name and person-level jail identifier. |
| Booking number | Event-level booking identifier for one jail intake. |
| Booking and release dates | Intake time and release time if no longer held. |
| Prisoner type | Operational category such as newly charged or local warrant. |
| Booking origin | Agency source, which can show Columbia County Sheriff's Office. |
| Bond and bail totals | Public totals and bond table entries when available. |
| Charges table | Charge description, offense date, docket, disposition, class, and arresting agency columns. |
Columbia County Jail Versus DOC
County jail custody and state prison custody should not be mixed. Walla Walla Corrections is the local jail path for Columbia County arrests, pretrial holds, local warrants, and short local sentences. The Washington State Department of Corrections locator is for people currently incarcerated in state custody after a DOC sentence. A historical county booking may remain online even when the current location has moved to DOC.
| Custody Type | Where to Look | Common Records |
|---|---|---|
| Columbia arrest before case resolution | Walla Walla Inmate Inquiry | Booking, charge rows, bond, booking origin. |
| Sentenced state prisoner | WA DOC incarcerated search | DOC number, name, age, location. |
| Federal sentence | BOP inmate locator | Federal inmate records from 1982 forward. |
| Immigration detention | ICE detainee locator | Adult ICE custody or CBP custody over 48 hours. |
Columbia County Detention Facilities
No separate state prison, federal prison, ICE detention center, or city jail was located inside Columbia County in the official sources reviewed. The detention facility page set therefore has one serving local jail. Nearby Washington State Penitentiary is in Walla Walla County and belongs in the DOC lookup discussion, not as a Columbia County facility page.
- Walla Walla County Corrections Department holds adults booked by Walla Walla agencies and Columbia County Sheriff's Office after the Columbia jail closure.
For victim notification, Walla Walla also points users to Washington VINE. VINE can send release, transfer, escape, or death notifications, but it should not be the only safety plan.
Columbia County Roster Sources
The official Columbia County Sheriff page is the source that explains why the local roster path now points to Walla Walla Corrections.
That notice is what separates this county from counties with a stand-alone jail roster.
The Walla Walla Inmate Inquiry supplies the public roster search form for Columbia County detainees now held there.
The form supports name, subject number, booking number, date, current-custody, and housing-facility filters.
