Find Lyon County Jail Inmates

Lyon County Jail Overview

Lyon County Jail is part of the Lyon County Sheriff's Office jail and detention function. The sheriff page describes the office as made up of law enforcement, dispatch and communications, and jail or detention. The official jail page says the jail is responsible for all inmates brought into the facility by deputies, State Troopers, federal agents, DNR, and DCI agents. It also holds local-area inmates, people held for other agencies on warrants, and federal inmates.

The current sheriff is Sheriff B. Hilt. The county staff page says he was elected in November 2024 and sworn in January 2025. The jail page says the facility is staffed 24 hours a day, and the direct jail phone is 712-472-8356. The county courthouse address is 206 S. 2nd Ave., Rock Rapids, IA 51246, while arrest-log and jail context identify the jail location as 410 S. Boone St., Rock Rapids.

The official Lyon County Jail page shows the jail roster, arrest log, warrant list, FAQ, work-release information, and visitation material.

The screenshot source matches the facility because it is the official county page for jail operations and public custody links.

Lyon County Jail Population

The official jail page gives Lyon County Jail a design capacity of 26 inmates. The inspected Current Inmates PDF was updated on 06/12/2026 at 20:03 and listed 18 people. That was about 69 percent of the published design capacity at the time of inspection. It is a snapshot, not an annual average, but it is useful because the roster is county-published and time stamped.

The jail separates inmates into male and female, federal, work release, general population, holding cell, detox cell, and special status categories. The public visitation schedule uses F Block, G-Block, M Block, S Block, and W Block labels. Those block names matter for visitors because the inmate must tell family or friends which visit window applies to the assigned housing unit.

Who Lyon County Jail Holds

Lyon County Jail is not limited to one arrest type. The roster and jail page show a broader custody mix. People may be booked on new criminal charges, active warrants, holds for other agencies, sentences to serve locally, or contract-prisoner status. The jail also houses federal inmates according to the sheriff's jail page, although that does not make the jail a Bureau of Prisons facility.

• Local arrests from Lyon County deputies and other law-enforcement agencies.
• Warrant custody when a person is arrested on an outstanding warrant.
• Other-agency holds where another agency has an interest in custody.
• Short local sentences or serve-sentence entries on the county roster.
• Work release for court-approved inmates who meet local rules.
• Federal inmates held locally under the sheriff jail page's described authority.

Look Up Lyon County Jail Inmates

The correct lookup for this county jail is the Current Inmates PDF. It is a public PDF, not a vendor search portal. The roster shows booked-in date, inmate name, reason booked description, charge text, bond amount, and update timestamp. It does not show mugshots, DOB, booking number, housing unit, arresting agency, court date, or release date.

1. Open the Current Inmates PDF from the sheriff's jail page.
2. Use PDF find to search the person's name.
3. Compare the booked-in date, reason booked, charge description, and bond amount.
4. If the person is not listed, check the arrest log and warrant list before moving to court or state records.
5. Call the jail at 712-472-8356 for current custody confirmation.

The arrest log is useful for people recently booked or released, and the warrant list is useful for active warrant status. Sentenced Iowa prison custody belongs in Iowa DOC Offender Search, not the county roster. Federal sentenced custody belongs in BOP's locator, and immigration detention belongs in ICE ODLS.

Lyon County Jail Contact

The jail information line is the best route for current custody, bond, visit, fingerprint, or emergency-message questions. The research did not locate a separate online bond-payment portal or video-visit vendor for Lyon County Jail, so phone confirmation is important before a family member sends money or travels for a visit.

Lyon County Jail Visits

Visitation is based on the inmate's housing unit. The FAQ says the inmate can contact family or friends and tell them which visit time applies. Visitors must not have been incarcerated in Lyon County Jail in the past 90 days, must be on the inmate's visitor list, must bring valid ID, and minors must be with a parent or guardian. The published schedule is block-specific.

Lyon County Jail Money

The FAQ says money may be sent to an inmate by U.S. mail as a check payable to the inmate or as a money order. The jail cashes the money and deposits it into the inmate's commissary account. Inmates can use commissary for necessary items and calling cards, and canteen occurs two times per week. Emergency messages may be left through the jail.

Lyon County Jail Fees

Lyon County publishes local jail charges under Iowa Code 356.7. The jail page states that room and board is charged to each inmate booked and housed in the jail, and unpaid room and board can result in a lien. Work-release fees are collected one week in advance, and money owed to the sheriff must be paid before work release is granted.

Lyon County Jail Release

The FAQ defines bond as the amount of money needed for release. It says bond is set by Iowa statute or by a magistrate, and the jail releases the inmate after it receives the proper bond amount. It also says cash only unless the bond is posted through a bondsman. A domestic arrest requires the inmate to see the magistrate before release, and an alcohol-related offense requires a minimum 8 hours.

Work release is court-approved only. The FAQ says the inmate must be serving more than a 14-day consecutive sentence and must have prior court approval. The sheriff page links an inmate work-release form packet, and the local rules require work-release fees to be paid in advance. These details make work release a court and jail process, not a roster status that family can arrange on its own.

Magistrate review

The first judicial review after booking; the FAQ says the magistrate must see the inmate within 24 hours.

Cash-only bond

A bond type that requires cash unless posted through a bondsman under local FAQ language.

Detainer or hold

An agency interest that may keep a person in custody even after a local charge changes.

Lyon County Jail Records Limits

Lyon County Jail publishes useful records, but not every record is online. The current roster, arrest log, and warrant list did not include mugshots in the inspected source set. Juvenile names and addresses were redacted in the arrest log. Iowa Code Chapter 22 supports public access to government records, while Iowa Code 22.7 and other laws can protect confidential or investigative information.

For booking photos or older booking records, a request should identify the person, booking or arrest date, incident number if known, and the exact record sought. For filed charges and court case documents, use Iowa Courts Online or the Lyon County Clerk of Court rather than the jail roster. For sentenced prison custody, use Iowa DOC. For federal and immigration custody, use BOP or ICE systems.
