The Oneida County Inmate Population
The Oneida County inmate population is not one simple jail list. The local jail in Rhinelander holds people arrested by the sheriff, Rhinelander police, other local agencies, and state officers. It also holds county-sentenced inmates, Huber/work-release inmates, and Wisconsin DOC state-contract prisoners. McNaughton Correctional Center in Lake Tomahawk is different. It is a Wisconsin DOC correctional center for sentenced adult men, so its residents are searched through the state locator instead of a county jail roster.
The Oneida County Sheriff's Corrections Division describes the jail as a county facility that also houses state inmates. That contract role is the key local fact. A person may be in the same jail building as a local pretrial detainee, a county-sentenced inmate, or a sentenced state prisoner placed there by DOC. A custody search should start with the jail or VINE for a current local hold, then move to Wisconsin DOC for prison custody, WCCA/CCAP for court charges, and BOP or ICE for federal or immigration custody.
Oneida County Inmate Population Statistics
Population figures come from several sources, and each source measures a different thing. The sheriff reports the jail's bed capacity and local operating role. Wisconsin DOC's Office of Detention Facilities reports annual county jail admissions. DOC weekly population reports show state-contract prisoners housed in the Oneida County Jail and the count at McNaughton. Wisconsin Public Radio adds useful 2020 context from Sheriff Grady Hartman about local jail use and the state contract.
| Measure | Figure | Source / Date |
|---|---|---|
| Oneida County Jail capacity | 200 beds | Oneida County Sheriff's Corrections page, inspected July 3, 2026 |
| Adult county jail admissions | 1,713 | Wisconsin DOC ODF Annual Report, 2025 |
| Local jail population context | High 90s average local inmates | WPR report quoting Sheriff Hartman, 2020 |
| McNaughton operating capacity | 102 adult male inmates | Wisconsin DOC McNaughton facility page |
| McNaughton recent population | 118 to 120 in sampled 2026 weekly reports | DOC weekly population reports, Jan. to Mar. 2026 |
The official Corrections page is the best visual source for the county jail's own capacity statement and operating description.
The screenshot ties the capacity figure to the local sheriff source rather than to a third-party roster page.
Oneida County Inmate Population Trends
The clearest local trend is admissions, not daily headcount. The 2025 Wisconsin DOC ODF annual report lists Oneida County adult jail admissions from 2018 through 2025. Admissions dropped sharply in 2020, then rose again in 2022 and 2023 before declining in 2024 and 2025. That trend should not be read as the same as the number of people sleeping in the jail on a given night, since admissions count bookings over the year.
| Year | Adult Jail Admissions | Local Context |
|---|---|---|
| 2018 | 2,451 | Pre-COVID baseline in the ODF table |
| 2019 | 2,103 | Lower than 2018 |
| 2020 | 1,252 | COVID-era drop |
| 2021 | 1,372 | Partial rebound |
| 2022 | 1,777 | Continued rebound |
| 2023 | 2,087 | Near 2019 level |
| 2024 | 1,885 | Down from 2023 |
| 2025 | 1,713 | Down 9.1 percent from 2024 in the ODF report |
State-contract beds make the total jail building count different from local admissions. DOC weekly reports in early 2026 showed roughly 120 male state-contract prisoners in Oneida County Jail on sampled dates. WPR reported that the county contracted with the state for about 100 prisoners at a time around 2020. Those numbers explain why the Oneida County inmate population can look larger than the local pretrial population alone.
Who Makes Up Oneida County Inmates
The county's own demographic breakdown was not located in official county sources. The known categories still matter. Oneida County Jail holds local pretrial detainees, county-sentenced inmates, Huber/work-release inmates, and state-contract inmates. McNaughton holds sentenced adult male Wisconsin DOC persons in care. Statewide ODF data reported Wisconsin county jails at 76 percent male and 24 percent female in 2025, but that is a statewide jail figure, not a Oneida-only breakdown.
- Local pretrial custody: People arrested in Oneida County who are waiting for bond, charging, hearings, or release.
- County sentences: People serving a jail term locally rather than a prison sentence.
- Huber and work release: Eligible inmates may have court-approved work or program movement under jail rules.
- State-contract prisoners: Wisconsin DOC prisoners can be housed temporarily in Oneida County Jail under state contract.
- State prison residents: McNaughton residents are sentenced DOC inmates searched through the state locator.
Oneida County Jail Capacity
Official local sources do not describe Oneida County Jail as overcrowded. The more precise local issue is unused or extra local bed space being filled through a state-contract arrangement. The sheriff page says the jail houses approximately fifty inmates from the Wisconsin prison system, while WPR reported about 100 contract prisoners around 2020 and DOC weekly reports showed 120 to 121 male contract beds in early 2026. Those source differences should be kept with their labels, because they measure different dates and possibly different operating categories.
McNaughton has its own capacity-definition issue. DOC's public facility page gives an operating capacity of 102 adult male inmates. The 2024 PREA audit listed designed capacity at 112, current population at 110, and prior-year average daily population at 108. Early 2026 DOC weekly reports listed 118 to 120 people, while using a separate design-capacity column of 55. For public use, the safest reading is that capacity and population figures depend on which DOC report is being used.
Laws Governing Oneida County Inmates
Wisconsin public-record and jail-standards law controls what can be requested, what may be withheld, and how jail facilities are overseen. These laws do not create a guaranteed public online roster for Oneida County. They do support requests for jail records, booking information, photographs, reports, and related materials through the proper legal custodian, with redactions when required.
Key Wisconsin Rules:
Wis. Stat. 19.31 states Wisconsin's policy that the public is entitled to broad information about government acts.
Wis. Stat. 19.35 gives requesters the right to inspect or copy records, subject to exceptions and fees.
Wis. Stat. 301.37 supports DOC oversight of local detention facilities.
Wis. Admin. Code ch. DOC 350 sets minimum standards for Wisconsin jails and houses of correction.
Search Oneida County Inmates
No official Oneida County Sheriff's Office current-inmate roster was located on the sheriff or county site during the research pass. That changes the search order. A current custody check starts with the jail information line, then Wisconsin VINELink, sheriff records, WCCA/CCAP for filed charges, and Wisconsin DOC for sentenced state custody. Federal and immigration cases use separate BOP and ICE systems.
- Call Oneida County Jail at 715-361-5180 for current custody, bond, and facility status questions.
- Use Wisconsin VINELink for custody status and notification when a record is available.
- Call sheriff records/reports at 715-361-5100 during posted records hours for jail records, photos, incident reports, and related records.
- Search WCCA/CCAP for filed charges after the District Attorney opens a case.
- Use the Wisconsin DOC Offender Locator for sentenced DOC custody and supervision records.
The Wisconsin VINELink page is the statewide notification channel linked by local public-safety and court sources.
VINE is useful when the county does not publish a current roster, but the jail remains the final source for bond and in-facility questions.
Current Oneida County Inmate Lookup
Since no official online roster was found, the county jail search-field table is a negative table. That is still important. It prevents a reader from relying on an unofficial roster that may be stale, scraped, or from another jurisdiction. Use the jail phone, VINE, and records request path for county custody; use DOC for state custody.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| No official Oneida County Jail public roster located | N/A | N/A | No sheriff/county online search form was found in official sources. |
| Jail phone check | Phone | Best first step | Use 715-361-5180 for current custody and bond status. |
| VINELink | Web custody notification | Optional | Search Wisconsin custody status and register for notifications when available. |
| Sheriff records | Phone or records request | Use for records | Ask for releasable jail records, reports, photographs, or recordings. |
Oneida County Inmate Records
Oneida County inmate records may include more than a roster line. The sheriff's Support Services Division maintains accident reports, incident reports, officer reports, photographs, recordings, E911 records, and jail records. Public release depends on the record type, pending investigation status, court orders, juvenile or victim privacy, medical privacy, and Wisconsin's public-record balancing test.
| Record Item | Where to Check |
|---|---|
| Current custody | Jail phone or VINE |
| Filed charges | WCCA/CCAP and Oneida County Clerk of Courts |
| Booking photo | Sheriff records/support services request, if releasable |
| Bond status | Jail, court order, warrant, or Clerk of Courts |
| Sentenced DOC status | Wisconsin DOC locator |
| Federal custody | BOP locator or ICE ODLS, depending on custody type |
County Jail vs State Prison
A Oneida County inmate search fails when the wrong system is used. County jail custody is local and often tied to a recent arrest, short sentence, warrant, Huber privilege, or bond status. State prison custody is a Wisconsin DOC record after conviction and sentencing. Federal custody and immigration detention are separate from both.
| Question | Oneida County Jail | Wisconsin DOC / Other Systems |
|---|---|---|
| Who is covered? | Pretrial detainees, county-sentenced inmates, Huber inmates, and some state-contract inmates | Sentenced DOC persons in care, federal prisoners, or ICE detainees |
| Where to search? | Jail phone, VINE, sheriff records, WCCA for charges | DOC locator, BOP locator, or ICE ODLS |
| What record appears? | Custody, bond, booking, and jail records when releasable | Prison facility, DOC number, release/supervision data, or federal locator fields |
| Who runs it? | Oneida County Sheriff's Office | Wisconsin DOC, Federal BOP, or ICE |
Oneida County Detention Facilities
Two confirmed facilities serve different parts of the Oneida County inmate population. The county jail handles local custody and state-contract jail placement. McNaughton is a state correctional center physically inside the county, but it does not function as the county jail.
- Oneida County Jail holds local pretrial detainees, county-sentenced inmates, Huber/work-release inmates, and Wisconsin DOC state-contract inmates.
- McNaughton Correctional Center holds sentenced adult male Wisconsin DOC persons in minimum/minimum-community custody.
- Huber
- Wisconsin work-release jail status for eligible inmates who may leave for approved work or activities.
- Detainer
- A hold from another agency that can keep a person in custody after local bond is addressed.
- DOC person in care
- Wisconsin DOC term for a sentenced person held or supervised by the state correctional system.
Oneida County Inmate Population FAQ
How large is the Oneida County inmate population?
The answer depends on what is counted. The sheriff lists Oneida County Jail as a 200-bed facility. The 2025 ODF report lists 1,713 adult county jail admissions for the year. McNaughton adds a separate state prison population, with DOC sources showing operating capacity and weekly population figures.
Is there an online Oneida County jail roster?
No official current-inmate roster was located on the sheriff or county site during research. Call the jail, use VINE, and request jail records through sheriff records/support services instead of relying on unofficial roster pages.
Why does the county jail house state prisoners?
The sheriff's Corrections page and WPR reporting describe a state-contract relationship. Wisconsin DOC prisoners may be housed in the county jail, which means a person in the building may be local or state custody.
Where are court charges after an arrest?
Filed charges are searched in WCCA/CCAP and through the Oneida County Clerk of Courts. Jail booking labels can differ from the prosecutor's filed complaint and later court record.
