Clinton County Jail Overview
Clinton County Jail is operated by the Clinton County Sheriff's Office from the Law Center in downtown Clinton. It is the only local detention facility mapped for Clinton County, Iowa in the research file. Official sources did not identify a separate Clinton, DeWitt, or Camanche city jail. They also did not confirm an Iowa DOC prison, BOP facility, or ICE detention facility inside Clinton County, Iowa. Municipal arrests and sheriff arrests route into the county jail for booking and custody processing.
The jail serves the normal county role. It can hold pretrial detainees, people arrested by local police or sheriff's deputies, sentenced misdemeanants, out-of-county holds, court holds, probation or DOC-related holds, and people with judge-set bond conditions. The roster's agency filter includes Clinton County Sheriff's Office, Clinton Police Department, DeWitt Police Department, Camanche Police Department, courts, Iowa DOC, U.S. Marshals, and many outside agencies, which supports the jail's role as a local custody hub.
The Clinton County Sheriff's Office page lists Sheriff Bill Greenwalt and the Law Center contact details used for jail and records questions.
The sheriff page matters because it connects jail custody to the office divisions, public hours, device ban, and Records Division fallback.
Clinton County Jail Capacity
The strongest official public source for Clinton County Jail capacity is the July 2014 Justice Needs Assessment. It described the jail as a 44-bed facility with a six-bed work release area and 10 temporary beds available for less-than-24-hour housing. The same report referenced 45 operating capacity in its operational assessment and projected a 96-bed future requirement if a new facility were designed to meet county needs.
The assessment reported 1,865 bookings during calendar year 2012 and an average daily population of 38.63. A live public roster API check returned 58 records for the June 13, 2026 in-custody date. That 58 figure is a public roster count for one searched date, not an average daily population and not a formal finding that the current jail is over capacity. Current capacity should be verified with the Sheriff's Office before making operational claims.
Search Clinton County Jail Inmates
The correct lookup system for this county jail is the official Clinton County inmate roster. The roster is linked from the Sheriff's jail page as "Who's in Jail." It covers people in Clinton County Jail for a current or recent in-custody date. It is not the Iowa DOC locator, and it is not a federal or immigration detention search.
- Open the official roster through the Sheriff's jail page or the CentralSquare portal.
- Set In Custody On within the prior seven-day limit used by the county portal.
- Search by name if a date-only search returns too many Clinton County Jail inmate rows.
- Use Held For Agency if the arrest involved a city police department, court, DOC, U.S. Marshals, or outside county.
- Read the public row for mugshot, name, age, race, sex, arrest date, release date, held-for agency, and hold reasons.
If the roster fails, call the jail at 563-242-9211. If the person was sentenced to state prison, use Iowa DOC offender search. If charges have been filed in court, use Iowa Courts Online rather than relying only on the jail hold text.

Booking at Clinton County Jail
Booking begins after an arrest by the Sheriff's Office, Clinton Police, DeWitt Police, Camanche Police, Iowa State Patrol, DNR, a court warrant, or another agency whose hold is accepted. The 2014 assessment describes temporary holding cells for intake, processing, and movement. A normal intake sequence can include identity checks, warrants and holds, property inventory, booking photo, fingerprints when required, medical or mental-health screening, classification, housing assignment, phone or tablet access, and first appearance or bond review.
The roster may show a mugshot and hold reasons after booking, but no official refresh interval was located. Bond details should be verified with the jail or court because public hold reasons can include several charges, cash-only bonds, cash/surety bonds, no-bond holds, multiple-case bonds, and "Set By Judge" language. A local bond does not always produce release if a second agency or court hold remains active.
Clinton County Jail Building History
The July 2014 Justice Needs Assessment described the Law Enforcement Center as built in 1969, with the jail on the second floor. It described a ring or linear cell layout, temporary holding cells in the core, and first-floor sheriff functions, sally port, and outdoor recreation. The report identified old bars, single-pane exterior windows, sanitary piping concerns, HVAC issues, isolation-cell mechanical limits, no secure master control station, and limited flexibility for classification or expansion.
The county's later jail inspection records provide current oversight context. The 2021 Iowa DOC virtual inspection examined training records, required documentation, and prisoner files, and found Clinton County Jail in compliance with Chapter 50, Iowa Jail Standards. The county hosts an inspection reports index for 2006 through 2021, making jail standards and inspection history part of the public record surrounding the facility.
The jail inspection reports index shows the official inspection archive for Clinton County Jail.
The inspection archive supports facility-level research without treating old planning findings as current operational claims.
