The Lyon County Inmate Population
The Lyon County inmate population is served by one local adult detention facility, the Lyon County Jail in Marshall. The jail is run by the Lyon County Sheriff's Office and is the first custody point for many arrests made by the sheriff, Marshall Police, Tracy Police, Minneota Police, Minnesota State Patrol, and other agencies that book people into the county facility. Local custody can include new arrests, pretrial detainees, people serving local jail sentences, probation or parole violators, state-prison transfer holds, and people held for another jurisdiction when accepted.
The county jail count is not the same as the Minnesota state prison count. A person arrested in Lyon County may appear on the county roster while held before court or while serving a local sentence. After a felony prison commitment and transfer, the search shifts to the Minnesota Department of Corrections offender locator. Federal inmates use the BOP inmate locator, and immigration detainee searches use ICE's detainee locator. That split is the most common reason a name can disappear from the Lyon County jail roster even though the person is still in custody somewhere else.
Lyon County Inmate Population Statistics
Lyon County's official sources publish capacity and snapshot data, but they do not publish a full annual jail population report with bookings, average length of stay, or demographic totals. The county-facing jail page gives an 87-bed design capacity. The Minnesota DOC 2024 jail inspection lists 88 approved secure coed beds and 74.80 operational beds. The current roster inspected for research showed at least 27 visible entries on June 18, 2026, but that is a dynamic custody snapshot rather than an annual average.
| Measure | Figure | Source / Date |
|---|---|---|
| County jail designed maximum capacity | 87 beds | Lyon County About the Jail page, inspected June 18, 2026 |
| DOC approved secure coed capacity | 88 beds | Minnesota DOC 2024 inspection, inspected October 9, 2024 |
| DOC operational capacity | 74.80 beds | Minnesota DOC 2024 inspection, 85 percent operating capacity |
| Visible roster snapshot | At least 27 entries | Current roster inspected June 18, 2026 |
| Annual bookings | Not located in official sources | County jail pages, DOC inspection, and roster checked |
Lyon County Inmate Population Trends
The strongest trend record is the change from the older jail era to the current facility. Historical project notes reviewed in the research described the former 37-bed jail as averaging about 50 inmates, with 20 to 25 people usually housed in other counties. Lyon County's current jail began full operations in 2010 and gave the county a larger local facility. The 2024 DOC inspection then gives the modern regulatory capacity snapshot.
| Year or Date | Population or Capacity Measure | Use in Context |
|---|---|---|
| Pre-2010 old jail era | 37 beds, average population around 50 | Historical overcrowding context from project notes |
| 2010 | Current jail began full operations | County jail building history |
| December 31, 2013 | 44 jail population snapshot | Prisoners of Census correctional population reference |
| October 9, 2024 | 88 approved, 74.80 operational | Minnesota DOC inspection capacity table |
| June 18, 2026 | At least 27 visible roster entries | Current roster snapshot, not average daily population |
Lyon County Jail Capacity
The visible roster snapshot from June 18, 2026 was below both the county's 87-bed design figure and the DOC's 74.80 operational capacity figure. That does not prove the jail is always below capacity, because the roster changes and the research did not locate average daily population by month or year. It does support a careful statement: the current public snapshot did not show crowding above the published capacity numbers.
The 2024 DOC inspection is useful for standards context. It was a biennial inspection under Minnesota Rules chapter 2911, with a walk-through, interviews, file review, document review, and video footage review. The report listed four mandatory rules not in compliance, including a dated finding about a written disaster plan and evacuation drill documentation. The build should treat that as 2024 inspection history unless a newer report confirms status.
Laws for Lyon County Jail Data
Minnesota law gives the Lyon County inmate population its public-record frame, but it does not make every jail detail public. Booking and arrest data can be public in one setting while medical, mental-health, security, juvenile, victim, witness, or active-investigation details remain private or confidential. The jail roster is therefore a public custody tool, not a complete jail file.
Key Minnesota authorities:
Minnesota Statutes section 13.82 governs law-enforcement data, including arrest data, protected identities, and warrant-index confidentiality.
Minnesota Statutes section 13.85 classifies corrections and detention data, including limits on private individual detention information.
Minnesota Statutes chapter 641 covers county jail commitments, inmate records, and jail administration duties.
Minnesota Statutes section 641.12 allows county boards to charge convicted inmates for room, board, clothing, medical, dental, and correctional costs.
Lyon County Inmate Population Makeup
The official research did not locate a county-published demographic split by age, race, sex, charge level, pretrial status, or sentence status. The roster did show practical custody signals. Entries included arresting agencies such as Marshall Police Department, Lyon County Sheriff, Murray County, Slayton Police Department, and Minnesota State Patrol. Status language included Bail Set, Hold Placed, Sentenced, Released Own PR, Time Served, and Chg Dismissed.
- Pretrial detainee
- A person held after arrest while a case, bond order, or first appearance is still moving through court.
- Hold placed
- A custody flag from another case, agency, warrant, probation matter, or jurisdiction that can block release.
- Released Own PR
- Release on a promise to appear, without paying cash bail up front.
- DOC transfer hold
- A local jail hold for a person sentenced to state prison but not yet moved to state corrections.
Search the Lyon County Jail Population
The official county search path starts at the Lyon County Jail roster page and opens the current roster report. The county says the roster updates automatically every 12 hours. Tracy Police links to the same roster and describes a 4 a.m. and 4 p.m. update cadence, which matches a twice-daily cycle.
Unlike many vendor portals, Lyon County's roster is a report-style page. It has no public search box, dropdown, date field, reset button, export, login, or payment gate. A practical Lyon County inmate search uses the browser's Find command, then checks the full row for booking date, arresting agency, charge text, and status before assuming a match.
- Open the county roster landing page, then choose the current Lyon County Jail roster report.
- Use browser Find for the last name, first name, or a partial spelling if the name is uncertain.
- Compare booking date, booking time, and arresting agency when common names appear.
- Read charge and status text as booking information, not as a final court outcome.
- If the person is missing after a recent arrest, wait for the next update or call the jail.
Lyon County Roster Lookup Fields
The roster's plain format is part of the local guidance. It is free and public, but the search happens in the browser, not in a county form. The roster image below comes from the official current report and shows why the best workflow is to scan entries rather than look for a hidden search form.
The official current Lyon County Jail roster report displays roster rows with booking and charge details.
The report supports custody lookup, but it does not replace court records or a jail phone confirmation when release, holds, or recent bookings are time-sensitive.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Search field | None | Not applicable | No public search input appears. Use browser Find. |
| Name | Roster text | Not applicable | Shown as last name, first name, and middle name when available. |
| Booking number | Roster text | Not applicable | A numeric value appears near the name. |

Lyon County Inmate Record Details
A Lyon County jail roster entry is a custody record. It can help locate a person and understand the booking status, but it is not a final criminal-history report. Court filings in Minnesota Court Records Online may later show amended charges, dismissed counts, pleas, sentencing, or warrants that are not fully reflected in the jail list.
| Roster Field | What It Shows |
|---|---|
| Mugshot | No booking photo was visible in the inspected public roster report. |
| Name | Person listed in last, first, middle format when available. |
| Booking date/time | When the jail intake was recorded. |
| Arresting agency | The agency tied to the booking or charge line. |
| Charge text | Plain-language offense information, sometimes with statute references. |
| Status | Custody or case-position terms such as Bail Set, Hold Placed, Sentenced, or Time Served. |
Lyon County Jail vs State Prison
The Lyon County inmate population changes systems at sentencing and transfer. The county roster is best for current local jail custody. MNDOC is best for adults committed to the Commissioner of Corrections and still under DOC jurisdiction, including state prison and post-release supervision. Newly sentenced people may take several business days to display in the DOC locator.
| Custody Type | Where to Look | What It Covers |
|---|---|---|
| County jail | Lyon County current roster | New arrests, pretrial custody, local sentences, and holds |
| State prison | Minnesota DOC locator | Sentenced prison and DOC supervision cases |
| Federal custody | BOP inmate locator | Federal inmates from 1982 to present |
| Immigration custody | ICE detainee locator | Current ICE custody and some recent CBP custody |
| Notification | Minnesota VINE | County custody status and release notifications |
State and Federal Inmate Search
The Minnesota DOC adult facilities list places state prisons outside Lyon County. That matters for families who know a Lyon County case ended in prison time. Once the person is committed to state corrections, the county jail roster is no longer the main lookup tool. Use the DOC locator by name or MNDOC offender ID, and remember that partial beginning letters can broaden a name search.
Federal and immigration custody are also outside the county roster. The BOP locator supports name and number searches for federal inmates. ICE searches can use an A-number or biographical details. The U.S. Marshals Service may house federal pretrial detainees in contract space outside a person's home county, so a missing Lyon County roster entry does not rule out federal custody.
Lyon County Detention Facilities
The facility map for this project has one Lyon County detention facility. No separate state prison, BOP institution, ICE detention center, regional jail, or county work-release building was located inside the county from the official sources reviewed. Local police departments route custody users to the county roster after booking.

Lyon County Inmate Population FAQ
How large is the Lyon County inmate population?
The best sourced current numbers are capacity and snapshot figures. Lyon County lists an 87-bed jail. The 2024 DOC inspection lists 88 approved beds and 74.80 operational beds. The roster snapshot inspected June 18, 2026 showed at least 27 visible entries, but that count changes and should not be used as an annual average.
How do I search Lyon County inmates?
Open the current roster report and use browser Find for a name or charge term. If the arrest is recent, wait for the next update or call the jail direct line. For sentenced prison cases, use MNDOC. For federal or immigration cases, use BOP or ICE.
Does the roster show every past inmate?
No. The roster is a current custody list. Past booking records, reports, or booking photos may require a sheriff data request, and release depends on Minnesota data practices rules and the case status.
