The Polk County Inmate Population
The adult Polk County inmate population is housed mainly at Northwest Regional Corrections Center, usually called NWRCC. The facility is operated by Tri-County Community Corrections, a joint powers agency that serves Norman, Polk, and Red Lake Counties. That structure matters. A roster count from NWRCC is not a pure Polk-only jail count. It can include people booked on Polk County charges, people from the two other member counties, State of Minnesota contract custody, warrants from other jurisdictions, and immigration holds that appear locally before a transfer.
The public adult jail roster is a weekday PDF snapshot, not a live search screen. The research file inspected a NWRCC roster printed June 18, 2026, and it showed 92 listed rows. That count is useful for reading the Polk County inmate population served by the regional jail on that morning, but it is not the same as average daily population, annual bookings, or a demographic report. Sentenced prisoners from Polk County who have moved to prison are searched through the Minnesota Department of Corrections public locator, not through the local jail roster.
The county law-enforcement fallback is the Polk County Sheriff's Office, led by Sheriff James Tadman. The sheriff's office does not operate the adult regional jail as a stand-alone Polk County Jail, but it handles arrest, incident, and records channels that help when a roster search does not answer the question.
Polk County Inmate Population Statistics
The best current local figures are capacity and a public roster snapshot. The NWRCC official page states that the jail is licensed by the Minnesota Department of Corrections as a Class III facility for up to 200 inmates. It also describes a direct supervision design with Alpha, Beta, and Delta/Omega housing units, plus Sigma for special management. The June 18, 2026 roster snapshot listed 92 people, which is about 46 percent of licensed capacity if the row count is compared with the 200-inmate license. That comparison should be read as a point-in-time roster-to-license figure, not as an official use rate.
| Measure | Figure | Source / Date |
|---|---|---|
| NWRCC licensed capacity | Up to 200 inmates | NWRCC official overview, inspected June 18, 2026 |
| NWRCC housing layout | Three 60-bed units plus Sigma | NWRCC official overview, inspected June 18, 2026 |
| Current public roster snapshot | 92 rows | NWRCC roster PDF printed June 18, 2026 at 7:38:38 AM |
| Polk County population | 30,545 estimate | U.S. Census QuickFacts, July 1, 2025 estimate table |
Polk County Jail Population Trends
Official multi-year average daily population, annual bookings, and average length of stay were not located in the inspected Polk County, Tri-County, or Minnesota DOC sources. That gap is important because a roster snapshot can show current custody, but it cannot prove a trend by itself. For Polk County inmate population research, the defensible local trend table is narrow: it records the current public PDF count and marks the older ADP fields as not located rather than inventing year-by-year numbers.
| Year or Date | Figure | Notes |
|---|---|---|
| June 18, 2026 | 92 roster rows | Public NWRCC PDF snapshot; not average daily population. |
| 2024 | Not located | No official NWRCC ADP or year-end count found in inspected sources. |
| 2023 | Not located | No official NWRCC ADP or year-end count found in inspected sources. |
| 2022 | Not located | No official NWRCC ADP or year-end count found in inspected sources. |
A reported regional staffing issue adds context without replacing current data. A December 2021 MPR News item noted that NWRCC could house 200 inmates but was closing a 60-bed unit because of staffing pressure. That older item supports a useful distinction: licensed capacity and operating capacity can differ. Current visitor, housing, or custody questions still need confirmation with NWRCC because the roster and jail operations can change faster than public reports.
How NWRCC Serves Polk County
NWRCC is regional by design. Tri-County Community Corrections was formed in 1976 and serves Norman, Polk, and Red Lake Counties from northwestern Minnesota. The adult jail sits in Crookston and is tied to the Polk County Justice Center area, but the jail population can include people whose cases are not Polk County cases. A person on the roster may be held on a Norman County charge, a Red Lake County charge, a state contract placement, an out-of-county warrant, a fugitive hold, or a local Polk County arrest.
The roster examples found in the research included parole violations, probation violations, domestic abuse order violations, drug charges, assault, DUI, fugitive-from-justice entries, failure to appear, and Hold - INS. Those categories can move the population without a new local trial. For example, a person with a parole hold may remain at NWRCC until the supervising authority acts, while a person sentenced to prison may leave the jail count and later appear in the Minnesota DOC locator.
The official NWRCC roster page is the source to start with for current adult custody. The screenshot below comes from that official roster landing page.
The page's attached PDF and weekday update notice explain why a Polk County inmate search should confirm the roster timestamp before relying on the result.
Laws Governing Polk County Jail Records
Minnesota's public-records framework controls what can be released about arrests, jail records, booking photos, and criminal history. The local record request page for the Polk County Sheriff's Office says accident, arrest, and incident report copies are available for release subject to data privacy laws. That means the public may be able to obtain some jail or arrest data, while active investigations, private data, juvenile data, protected identities, and other restricted records may be withheld or redacted.
Key Minnesota authorities:
Minn. Stat. ch. 13 sets the public, private, and confidential data framework used by state and local government offices.
Minn. Stat. section 13.82 governs law-enforcement data, including arrest data, incident data, investigative data, and booking photographs.
Minn. Stat. section 13.87 backs the public criminal-history search run through Minnesota DPS/BCA.
Minn. R. ch. 2911 sets Minnesota jail facility standards for items such as records, staffing, security, and inmate welfare.
Minn. Stat. section 241.021 covers correctional facility licensing, inspection, and certain death-in-custody or unusual occurrence reporting duties.
Juvenile data is handled differently. Minn. Stat. section 260B.171 limits juvenile law-enforcement and delinquency records, so Red River Valley Juvenile Center should not be treated like a public adult jail roster source.
Search the Polk County Inmate Population
The Polk County inmate population lookup begins with the NWRCC Local Inmate Roster page. It does not provide a last-name database. Instead, it links a current PDF roster that is updated Monday through Friday morning. The PDF inspected in the research was a 12-page roster generated from Police Central with visible columns for Inmate Photo, Incarceration Date, Date of Birth, and Controlling Charge. Since it is a snapshot, a person booked after the PDF was printed may not appear until a later update.
- Open the NWRCC Local Inmate Roster page and select the attached current roster PDF.
- Check the printed timestamp at the bottom of the PDF before relying on the custody count.
- Use the browser or PDF Find function for last name, first name, charge term, or a statute number.
- Read across the row for photo column, incarceration date, date of birth, and controlling charge.
- If no match appears, check release, transfer, DOC commitment, ICE, USMS, BOP, MCRO, or sheriff records-request channels.
| Roster Field | Type | Required | Notes |
|---|---|---|---|
| Search fields | None | Not applicable | NWRCC does not expose a public web search form. |
| PDF browser Find | Text search | Optional | Use it for names, charge words, or statute numbers. |
| Buttons | Link only | Not applicable | The roster page links the dated Inmate_Roster PDF. |
| Refresh notice | Text notice | Not applicable | The roster says it is updated each Monday through Friday morning. |
| Login or fee | None | Not applicable | The public PDF was free and did not require login. |
Polk County Inmate Record Fields
A NWRCC roster row is lean. It helps identify current custody, but it is not a full booking packet, bond sheet, court calendar, or criminal-history report. The public PDF showed a photo column, name, incarceration date, date of birth, and one controlling charge. It did not show booking number, bond amount, arresting agency, court date, housing unit, judge, warrant number, projected release date, or all possible charges beyond the controlling charge.
| Field | What It Shows |
|---|---|
| Inmate Photo | Photo column on the public PDF roster. |
| Name | Roster name in last-name order, with some names wrapping across lines. |
| Incarceration Date | Date the person entered the current NWRCC custody episode. |
| Date of Birth | Full DOB visible on the inspected public PDF. |
| Controlling Charge | Main listed charge or hold, often with a severity abbreviation and statute citation. |
| Total Number of Rows | Snapshot count for the PDF, useful for population context. |
- Controlling charge
- The main charge or hold displayed on the roster snapshot. It may differ from formal prosecutor-filed charges.
- Hold or detainer
- A request or legal reason from another agency or court to keep a person in custody.
- Classification
- A jail decision about housing and supervision based on risk, needs, behavior, and facility rules.
Past Polk County Inmate Records
Released people may disappear from the current NWRCC PDF because the roster is built for current custody, not archive research. For an older Polk County arrest, booking, or incident record, use the Polk County Sheriff's Office Record Requests page. The sheriff's records division handles crime and arrest records, traffic accident reports, citations, civil process, initial files, investigative files, and related documents. The request is subject to Minnesota data practices law, so a public record may still be redacted or denied in part.
The record request form is titled Request for Information under the Minnesota Government Data Practices Act. It asks for requester information, a description of the requested data, proof of identity when needed, and staff classification fields. No specific fee or processing time was located in the inspected official pages. For practical use, include the person's full name, approximate arrest date, agency or case number if known, and a plain description such as arrest report, booking photo, or incident report.
The sheriff's record request page is shown below from the official Polk County website.
That page is the local fallback when a current roster search does not provide past custody or report details.
Polk County Jail vs State Prison
County jail, state prison, federal custody, and immigration detention are separate systems. NWRCC covers the current regional adult jail population and local holds. Minnesota DOC covers adults committed to the Commissioner of Corrections who are in prison or still under DOC jurisdiction after release. Federal sentenced prisoners belong in the BOP locator. ICE detainees are searched in ODLS after transfer, while USMS information may require FOIA because NWRCC's roster page routes marshal inquiries that way.
| Custody Type | Where to Search | What It Covers |
|---|---|---|
| Current regional jail custody | NWRCC roster PDF | Local charges, state contracts, warrants, and holds at NWRCC. |
| Sentenced Minnesota prison custody | Minnesota DOC locator | Adults committed to DOC and still under DOC jurisdiction. |
| Federal sentenced custody | BOP Inmate Locator | Federal prisoners and many former federal inmates. |
| Immigration custody | ICE Online Detainee Locator | ICE detainees after transfer into the ICE locator workflow. |
The Minnesota DOC locator page documents search by name or MNDOC Offender ID. Newly sentenced people may take several business days to appear, so a recent NWRCC sentence can sit in a gap between county custody and the state locator.
Polk County Detention Facilities
Two facilities are part of the Polk County facility map. They serve different populations and should not be merged. NWRCC is the adult regional jail for public inmate roster purposes. Red River Valley Juvenile Center is a juvenile detention and placement facility, and no general public juvenile roster was located.
- Northwest Regional Corrections Center - adult regional jail in Crookston for Norman, Polk, and Red Lake County local charges, state contracts, warrants, holds, and some ICE/INS holds shown locally.
- Red River Valley Juvenile Center - juvenile secure detention and non-secure placement facility for adolescents, with access limited by juvenile privacy law.
The facility split is especially important for mugshots and rosters. Adult NWRCC records can appear in a public PDF. Juvenile records are restricted, and the adult roster should not be used as a substitute juvenile search tool.
Polk County Inmate Population FAQ
How big is the Polk County inmate population?
The best current local figure is the NWRCC public roster snapshot printed June 18, 2026, which showed 92 rows. That is a current roster count for the regional adult jail, not a Polk-only average daily population. Official Polk-only ADP, annual bookings, and demographic tables were not located in the inspected sources.
How do I search the Polk County inmate population?
Open the NWRCC Local Inmate Roster page, then open the attached current PDF roster. Use PDF Find for a name or charge term. If the person is not listed, check whether release, DOC transfer, ICE transfer, federal custody, a court case, or a sheriff's records request is the better channel.
Does Polk County have a sheriff app for jail lookup?
No official Polk County Minnesota sheriff or police mobile app with an inmate roster, warrant lookup, or custody feature was located in the research. Avoid wrong-state Polk County apps that appear in search results.
Are juvenile detainees part of the public roster?
No public Red River Valley Juvenile Center roster was located, and one should not be expected for general public use. Juvenile law-enforcement and delinquency records are restricted by Minnesota law.
