Blue Earth County Jail Overview
Blue Earth County Jail is a county-jail facility operated by the Blue Earth County Sheriff's Office. It is located inside the Blue Earth County Justice Center in Mankato, the same Carver Road campus that also houses sheriff operations, the County Attorney's Office, Community Corrections, and Blue Earth County District Court functions. The jail holds adults received by the county jail, current inmates, very recent releases, pretrial detainees, sentenced local inmates, work-release and scheduled-sentence reports, and people held pending court action or transfer.
The sheriff listed in the county staff directory is Jeff Wersal. Jail administration is led by Jail Administrator Joslyn Lachmiller, with Assistant Jail Administrator Darrin Ewert. The facility is not a state prison, federal prison, or ICE detention center. People sentenced to the Commissioner of Corrections are searched through the Minnesota Department of Corrections Public Viewer after transfer, while federal and immigration custody use separate federal systems.
Capacity, Operational Capacity, and Inspection Status
The Minnesota Department of Corrections 2025 inspection report for Blue Earth County Jail lists the facility as a local adult detention facility inspected under Minnesota Rule 2911. The inspection date was 05/14/2025. The report gives authority to operate from 07/01/2025 through 06/30/2027, identifies the Blue Earth County Sheriff's Office as certificate holder, and records delinquent juvenile hold approval for 6 hours.
For jail capacity, the same MNDOC report lists 146 approved secure coed beds, effective 07/13/2009. The report also applies a 90 percent operating capacity figure, producing 131.40 operational capacity. The live roster count is only a snapshot. The research capture for 06/18/2026 at 9:30:28 AM counted 81 visible inmate-entry blocks on the official roster report, which is not an annual population average or a guarantee of current occupancy at a later time.
How to Look Up an Inmate at Blue Earth County Jail
The official county jail roster is published at jailroster.blueearthcountymn.gov. It is a report, not a search form. The county's roster explainer tells users to use browser Find, usually Ctrl+F, to locate a name within the page. The roster can show an inmate photo, name, age, booking date and time, charges, arresting agency, case number, status, and projected release date field. For broader context on roster fields, see Blue Earth County jail inmate records.
- Open the official Blue Earth County Jail Roster Report.
- Use browser Find or Ctrl+F and type the person's last name, first name, or a distinctive part of the name.
- Move through matches and confirm that the entry is tied to Blue Earth County Jail.
- Read the booking time, charges, arresting agency, case number, status, and projected release date field if shown.
- If no match appears, remember that a person may be in intake and not listed until 24 hours after being assigned a booking number.
If the person was sentenced to state prison, use the MNDOC Public Viewer instead. If federal or immigration custody is involved, use the BOP Inmate Locator or ICE Online Detainee Locator System. Minnesota VINE is the notification route for county jail release notifications.
Blue Earth County Jail Address and Contact
The jail's public services entrance is separate from general courthouse counters. The county jail page says Jail Administration has its own entrance for fingerprinting, inmate visitation, and depositing money for inmates. Administrative services run during weekday business hours, while the lobby is open around the clock. For urgent custody confirmation, call the jail before relying only on a roster search, especially during the intake-delay window.

Bail, Work Release, and Documented Fees
Blue Earth County's bail instructions separate business-hours and after-hours cash bail. During business hours, bring the exact amount of cash to the Justice Center Jail Lobby. After business hours, use the Release Lobby. Jail staff provide the paperwork and receipt. For bail bondsman release, the county directs the user to contact a bail bondsman, complete the bondsman paperwork, and have the bondsman deliver paperwork to jail staff.
Some release conditions can delay release even after cash bail or bond paperwork is received. The county lists examples such as electronic home monitoring for alcohol or GPS, jail drug testing, probation contact before release, and victim notification. Electronic Home Monitoring questions route to Blue Earth County Probation at (507) 304-4750.

| Work-release booking fee | $30 cash | March 2025 work-release packet for people reporting to serve jail time. |
| Cash bail | Exact cash amount required | Jail Lobby during business hours or Release Lobby after hours. |
| Remote visiting | Per-minute charge, amount subject to change | Inmate Canteen remote visits, text, and email services. |
Booking, Intake, and Work Release Reporting
After an arrest or court-ordered jail report, the person is transported or reports to Blue Earth County Jail, goes through intake and identity processing, receives a booking number, and may then appear on the public roster. The county specifically warns that people may be in intake and not listed online until 24 hours after the booking number is assigned. That delay is important when a new arrest cannot be found with browser Find.
People ordered to report for a scheduled sentence or work release report to the Release Lobby at 401 Carver Road. The work-release packet says to bring a copy of the sentencing order, pay the $30 cash booking fee, and expect a breath test and possibly a urine sample. Reporting under the influence of alcohol or drugs can result in loss of release privileges and possible loss of good time. The Justice Center is tobacco free.
Jail Standards, PREA, and Facility Conditions
The 2025 MNDOC inspection is the main recent official operations record for Blue Earth County Jail. It confirms the facility's authority to operate, capacity basis, Rule 2911 inspection framework, certificate holder, and limited delinquent juvenile hold approval. Rule 2911 is the Minnesota local adult detention facility standards chapter covering areas such as capacity, staffing, records, reports, inmate welfare, security, health, sanitation, and discipline.
Blue Earth County also publishes program and condition material outside the roster itself. The county's Yellow Line Project describes goals of expanding service options, improving access to health care and treatment, and reducing unnecessary incarceration, systemic costs, and jail population. The county PREA material states that the Prison Rape Elimination Act is a federal law addressing sexual assault and sexual misconduct in correctional settings and that Blue Earth County Jail is committed to a safe and healthy environment for staff and offenders.
