Winnebago County Inmate Population Overview
Winnebago County's custody system is split between the sheriff-run jail and several state facilities. The Winnebago County Sheriff's Corrections Division publishes the official jail population tools: a current inmate list PDF and a 24-hour jail media blotter. Those county records cover local jail custody, including people booked after arrest, pretrial detainees, sentenced county-jail inmates, probation or revocation holds, hold/detain entries, and work-release or electronic-sanction statuses shown in the roster.
The state prison side is separate. The Wisconsin DOC Offender Locator is the right tool after a person has moved into DOC custody. That distinction matters in Winnebago County because Oshkosh Correctional Institution, Drug Abuse Correctional Center, Winnebago Correctional Center, and Wisconsin Resource Center are all local or nearby state custody facilities. A person can be tied to a Winnebago County criminal case but no longer appear on the county jail list after transfer to DOC.
Winnebago County Inmate Population Statistics
The official research captured a point-in-time county jail roster and stronger numeric data for the local DOC institutions. The Winnebago County Jail current list was a 10-page PDF with a run date, but the research did not manually compute the exact row count and did not locate an official county jail rated capacity. Those missing numbers should not be filled from estimates. State prison figures are more concrete because DOC pages and the Oshkosh Correctional Institution annual report publish operating capacity and population data.
| Measure | Figure | Source / Date |
|---|---|---|
| Winnebago County Jail current list | 10-page public PDF | Current Inmate List run date July 3, 2026 |
| County jail capacity | Not published in captured county source | Corrections page and jail FAQ reviewed |
| Oshkosh Correctional Institution capacity | 1,494 | OSCI 2025 Annual Report |
| Oshkosh Correctional Institution current population | 2,099 | OSCI 2025 Annual Report |
| Drug Abuse Correctional Center capacity | 294 adult male inmates | Wisconsin DOC facility page |
| Winnebago Correctional Center capacity | 266 adult male inmates | Wisconsin DOC facility page |
The strongest population pressure item in the research is at Oshkosh Correctional Institution. Its 2025 annual report listed a current population above operating capacity and an average daily population range of 2,070 to 2,100. By contrast, the county jail's public materials focus on who is currently held and who was booked or released in the last 24 hours, not a dashboard of long-term average daily population. That difference is useful for readers: state prison population data can support capacity comparisons, while the county jail list is best treated as a current custody snapshot.
Winnebago County Inmate Population Trends
The public research located the sheriff's annual report archive, but it did not capture official year-by-year jail average daily population numbers. The safest local trend statement is narrower: Winnebago County maintains current public jail PDFs, and the state facilities in the county publish capacity or program data through DOC or DHS pages. OSCI is the clearest trend signal because its 2025 annual report gives both capacity and current population.
| Year | Population / ADP | Use on This Site |
|---|---|---|
| 2023 | Not captured from official source | Do not estimate from non-official snippets |
| 2024 | Not captured from official source | Use sheriff annual reports only after manual review |
| 2025 | OSCI population 2,099 | Official state prison capacity context |
| 2026 | County current inmate list available by run date | Point-in-time jail roster lookup |
For a current Winnebago County inmate population check, the roster date matters more than an old trend line. The current inmate list answers whether a person is in the county jail at the roster run time. The media blotter answers whether a booking or release appeared in a recent 24-hour window. The DOC locator answers whether state custody has replaced local jail custody.
Winnebago County Jail Population Makeup
The county jail PDF uses a lean public format. Visible fields include InmateID, name, sex, judicial status, and initial booking. Judicial status labels observed in the research include PRETRIAL, SENTENCED, REVOCATION, PROBATION, HOLD/DETAIN, ES SANCTIONS, and PRESENTENCED. Those terms are custody labels, not final case outcomes. A pretrial entry means the person is held before final disposition. A revocation or probation entry may point to supervision authority rather than a new criminal charge.
- Booking
- The jail intake event after arrest, warrant arrest, court commitment, or transfer.
- Judicial status
- The county roster label for the person's current jail or case posture.
- Detainer
- A hold or request from another authority, such as another county, probation, or immigration.
- DOC
- The Wisconsin Department of Corrections, which covers sentenced state prison custody.
Laws for Winnebago County Jail Records
Wisconsin public-records law and jail standards explain why custody records exist, while also explaining why not every field is public. Wis. Stat. 19.31 states Wisconsin's policy of broad public access to information about government affairs. Wis. Stat. 19.35 gives a right to inspect or receive copies unless a legal limit, common-law limit, or balancing test applies. Wis. Admin. Code DOC 350 sets minimum standards for jails and houses of correction.
Records rule: Winnebago County jail data is public-records material, but release can still depend on custodian review, redaction, sealed records, juvenile limits, medical privacy, active investigations, and safety concerns.
Search Winnebago County Inmates
Start with the Winnebago County Jail Current Inmate List PDF. It is not a searchable county web database in the captured source. Open the PDF from the sheriff's Corrections page, check the run date, and use the PDF viewer's find function to search by last name. If the name is hyphenated, spaced, or commonly misspelled, search the shortest distinctive part of the last name.
- Open the sheriff Corrections page and choose the current inmate list.
- Check the run date before relying on the result.
- Use browser or PDF search to find the last name.
- Confirm identity with InmateID, full name, sex, and initial booking date.
- Use the media blotter for recent charges, releases, arresting agency, and complaint number.
- Call the jail information line if the roster and blotter do not answer the custody question.
The Jail Media Blotter PDF is a second official channel. It is better for recent event detail because it can show DOB, charges, hold type, type of arrest, release reason, arresting agency, complaint number, and arrest date. It is not the same as the current custody list.
Winnebago County Roster Fields
The county roster has no official search form fields because the public list is a PDF. The practical search fields are the PDF columns and the viewer's find box. For deeper charge detail, the jail media blotter provides a different record view. The two sources should be read together when a booking is recent.
| Field | Where It Appears | What It Means |
|---|---|---|
| InmateID | Current inmate list | County jail identifier for the row |
| Name | Current list and blotter | Roster name, sorted by name in the current list |
| Jud. Status | Current inmate list | Custody posture such as PRETRIAL, SENTENCED, or HOLD/DETAIN |
| Initial Booking | Current inmate list | First booking date and time for the custody stay |
| Charges | Media blotter | Recent booking charge and statute detail, not final court disposition |
| Release Reason | Media blotter | Release note when the blotter entry shows release |
The manifest image below is from the official county Corrections page, which links the current inmate list and jail media blotter. The Winnebago County Corrections page is the official starting point for those jail population PDFs.
That county page also points users toward bond rules, work release, visitation, mail, and court-date contacts, so it is more useful than a copied roster link alone.
Winnebago County Past Inmate Records
Released people drop from the current inmate list because the PDF is a custody roster. For older bookings, incident reports, booking details, or records not shown in the public PDFs, use the Sheriff's Records Division and the NextRequest public records portal. The portal is for sheriff-held records and warns that the sheriff can provide only records from the Sheriff's Office. If the arresting agency was Oshkosh Police, Neenah Police, DOC, or another office, that agency may be the records custodian for some materials.
For court-filed charges, do not rely on the jail list. Use Wisconsin Circuit Court Access and the Winnebago County Clerk of Courts copy process. The jail media blotter can give a starting point, but prosecutors may amend, dismiss, or add counts after review. The court record is the better source for filed charges, hearings, bond conditions, dispositions, judgments, and expungement entries.
County Jail vs State Prison
A Winnebago County inmate search often fails because the wrong custody system is being searched. The county jail roster covers local jail custody. The DOC locator covers sentenced prison custody and supervision. Federal and immigration systems use still different tools. Winnebago County also has a 2025 ICE 287(g) Warrant Service Officer agreement, so immigration holds may intersect with local jail custody without turning the county PDF into an ICE locator.
| System | Use It For | Official Tool |
|---|---|---|
| Winnebago County Jail | Current local custody, recent booking, release events | County current inmate list and jail media blotter |
| Wisconsin DOC | Sentenced state prison custody or supervision | DOC Offender Locator |
| Wisconsin Courts | Filed charges, court dates, dispositions, judgments | WCCA / CCAP and Clerk of Courts |
| Federal BOP | Post-sentence federal prison custody | BOP Inmate Locator |
| ICE | Current immigration detention or CBP custody over 48 hours | ICE Online Detainee Locator |
| VINE | Custody or case notification | Wisconsin VINE / VINELink |
Winnebago County Detention Facilities
The local custody map is dense for one Wisconsin county. The sheriff-run jail handles local jail custody. Three DOC adult facilities sit in or near Oshkosh and Winnebago. Wisconsin Resource Center is a DHS-managed treatment center that works with DOC referrals. Each facility has a different lookup path and should not be treated as one shared jail roster.
- Winnebago County Jail holds local pretrial, sentenced county-jail, probation, revocation, hold, and work-release related jail custody.
- Oshkosh Correctional Institution is a DOC adult male medium-security prison with its own state locator path.
- Drug Abuse Correctional Center is a DOC treatment center tied to the Earned Release Program.
- Winnebago Correctional Center is a DOC minimum-security center with work-release and community crew programs.
- Wisconsin Resource Center is a DHS/DOC specialized mental-health treatment center for referred prison residents.
Winnebago County Inmate Search FAQ
Does Winnebago County have a searchable jail roster? The official county roster is a current inmate list PDF, not a searchable web database. Use the PDF find function and check the run date.
Why is someone missing from the jail list? The person may have been released, transferred, listed under a different name, held in state prison, or held in a federal or immigration system.
Do the public jail PDFs show mugshots? The researched current inmate list and media blotter did not display booking photos. Booking-photo requests go through the proper records custodian.
Where are court dates listed? The county directs users to the Clerk of Courts or WCCA for court dates. The jail roster is not the court calendar.
Is there a sheriff app for inmate search? No official Winnebago County, Wisconsin sheriff app with a separate roster or warrant lookup was found in the research.
