Marquette County Jail Overview
Marquette County Sheriff's Office materials identify Marquette County Jail as the county jail at the sheriff's office and courthouse area in Montello. It is the official local detention point found in the county, state, federal, and immigration facility review. No separate county annex, regional jail, city jail roster, Wisconsin DOC prison, BOP prison, or ICE detention center was located in Marquette County. Municipal arrests in the county should be treated as county-jail matters unless an arresting agency gives different instructions.
The jail holds adult pretrial detainees, sentenced county inmates, male and female inmates, and people approved for Huber work-release or electronic-monitoring status. This is not the same as a sentenced state prison placement. Once a defendant is sentenced to Wisconsin state prison, lookup moves to the Wisconsin DOC locator. Federal sentenced custody uses BOP, and immigration custody uses ICE. Those distinctions prevent a common search error: calling the county jail for someone who has already been transferred into another system.
The official sheriff page is the best public doorway for the jail because it lists jail contact information and links to the vendor services used by families. The official Sheriff's Office page shows that same jail contact and service-link layout.
Marquette County Jail Contact
Use the jail contact card for custody confirmation, visitor questions, public-record request routing, and current instructions before travel. The sheriff page lists the main phone, non-emergency phone, and fax for the office. Research did not locate a separate public jail-records counter schedule, so call before arriving if the request involves records, visitation, property, bond payment, or accessibility needs.

Marquette County Jail Capacity
Two official sources describe the size of Marquette County Jail, and they should be read together. The 2025 PREA audit lists designed facility capacity as 52 beds. The Wisconsin DOC Office of Detention Facilities annual report lists Marquette County with 50 adult beds. The careful wording is that the jail is about 50 to 52 beds, depending on which official source and reporting context is being cited. No reliable multi-year average daily population trend, annual booking count, or full demographic dashboard was located in official county sources.
The 2025 PREA audit also supports important operational detail. It identifies the jail as an adult county jail with male and female detainees and minimum, medium, and maximum custody categories. It covers intake screening, inmate education on reporting sexual abuse or harassment, staff training, medical and mental-health response, grievance routes, and investigation procedures. Those details show a small local jail with formal safety standards rather than a state prison or a remote booking list.
Locate Marquette County Jail Inmates
No official online Marquette County Jail roster was found. Current custody should be checked by phone or in person with the Sheriff's Office/Jail. A caller should have the person's full name, spelling, date of birth or age if known, and the date or time of arrest. If the person is not in the jail, ask whether the person was released, transferred, taken to court, booked under another name, moved to DOC, or held by another authority.
- Call 608-297-2115 or 608-297-2116 and ask for current custody information that can be released publicly.
- Give the full legal name, date of birth or age, and the arrest date or case number if known.
- Ask whether bond has been set, whether a court appearance is scheduled, and whether any hold blocks release.
- Search Wisconsin Circuit Court Access after charges are filed for case number, charge status, bond events, and future hearings.
- Use the Wisconsin DOC locator, BOP, or ICE only when the person is no longer in local county jail custody.
For the fuller county lookup path, including record fields and state or federal fallbacks, use the Marquette County jail inmate records page. Marquette County Jail questions should stay tied to the facility itself: who is held there, how to contact staff, and what family members should confirm before visiting or sending funds.
Marquette County Jail Visitation
The reviewed sheriff material did not publish a complete public visitation schedule, video visitation schedule, dress-code page, child-visitor rule, or mail-policy page. That lack of a posted schedule should be stated plainly. Visitors should call the jail before traveling, bring government-issued photo identification, and confirm whether the visit is allowed that day. Attorney access is a separate professional channel and should be arranged directly with the jail.
| Topic | Officially Located Detail | Visitor Planning Note |
|---|---|---|
| In-person visits | Public schedule not located | Call before travel and ask about approved days, times, ID, and sign-in. |
| Video visits | Separate schedule not located | Do not assume video visits are available unless the jail confirms. |
| Visitor ID | Specific rule not published | Bring a current government-issued photo ID. |
| Dress code | Dedicated rule page not located | Use conservative clothing and expect jail staff to deny improper attire. |
| Minor visitors | Specific rule not published | Call ahead for guardian, age, and documentation requirements. |
| Attorney visits | Public schedule not located | Attorneys should contact the jail directly for professional access. |
Because the county sources do not publish parking rates, visitor entrance instructions, ADA entry details, or a full lobby schedule, callers should confirm those points at the same time they confirm visitation. Do not assume that the courthouse entrance, sheriff records entrance, jail intake entrance, and visitation entrance are the same.
Marquette County Jail Money
The sheriff page links Inmate Canteen for bond and account deposits and Reliance Telephone for inmate phone and texting service. Those vendor links are useful, but they are not the same as an official custody roster. Confirm the inmate's custody status and any bond amount with the jail or court before paying. If a court case has opened, WCCA can show bond events, but the jail or clerk should still confirm current payment instructions.
| Service | Source | What to Confirm |
|---|---|---|
| Bond or account deposits | Inmate Canteen | Custody, bond type, account setup, and whether payment clears all holds. |
| Commissary | Inmate Canteen link on sheriff page | No separate county commissary rule page was located; ask the jail for current limits. |
| Phone or texting | Reliance Telephone | Facility setup, account rules, rates, blocked numbers, and message limits. |
| No dedicated policy page located | Address format, inmate ID use, books, photos, scanning, and prohibited items. | |
| Huber or EM fees | County Huber/EM packets and fee schedule | Eligibility, fee due dates, schedule approval, and violation consequences. |
The sheriff's linked deposit source points families to the Inmate Canteen portal. Open it only after confirming the payment need with jail or court staff.
The Reliance Telephone Marquette facility page is the located communications vendor source for inmate phone and texting service.
Huber and Electronic Monitoring
Huber and electronic monitoring are a major Marquette County Jail detail because the county links several official Huber and Huber/EM application materials. Huber is a Wisconsin work-release jail status for eligible sentenced inmates. Electronic monitoring is a jail-supervised custody status that may allow approved activity outside the jail under strict schedule and equipment rules. Neither one is automatic. Both require jail approval, compliance with court and jail rules, and payment of any applicable fees.
The Huber and EM materials ask for identity, employment, schedule, contact, and rule-acknowledgment information. They also describe consequences for violations, including schedule problems, unauthorized activity, drug or alcohol issues, and failure to follow jail instructions. A person on Huber or electronic monitoring may still be under jail authority, so family members should not assume that an absence from a cell block means the person has been fully released.
- Huber
- Wisconsin work-release status for eligible sentenced inmates who may work or attend approved activities under jail control.
- Electronic monitoring
- A supervised custody status using monitoring equipment and strict approved schedules.
- Classification
- The jail process that helps decide custody level, housing, safety needs, and program eligibility.
Marquette County Jail Safety
The 2025 PREA audit is the strongest located source for jail safety and conditions context. PREA stands for the Prison Rape Elimination Act. The audit covers staff training, inmate education on reporting sexual abuse or harassment, intake screening for vulnerability or abuse risk, medical and mental-health response, grievance procedures, and investigation routes. It also confirms that the facility is a county jail with adult custody categories rather than a state prison.
Families with urgent safety, medical, or mental-health concerns should contact jail staff directly. Public web materials do not replace jail procedures for emergencies, grievances, medication, suicide risk, or threats. If the concern involves a filed criminal case, court staff and attorneys may also have a role, but immediate jail safety questions should begin with the facility.
Confirm before travel: Marquette County Jail does not publish every visitor, mail, and records detail online. Call the facility before arriving or sending items.
Directions to Marquette County Jail
Marquette County Jail is in Montello, the county seat, near the county-government and courthouse area on West Park Street. Visitors coming from east or west generally approach Montello by Wisconsin Highway 23 and then use the local downtown street grid. Visitors coming from north or south generally use Wisconsin Highway 22 or nearby county routes before turning toward the courthouse and sheriff's office area.
The county source gives the street address but does not publish special turn-by-turn jail visitor parking, public-transit, lobby-hour, or ADA entrance instructions. Plan private transportation unless a local option has been confirmed. Bring identification, avoid unnecessary property, and do not bring weapons, drugs, alcohol, or contraband into a jail lobby. For mobility accommodations or a special visitor intake need, call the main jail number before leaving.
