Finding Someone in Custody in Middleton
A person kept in custody after an arrest in Middleton is held at the county jail, run by the Dane County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Dane County Sheriff's Office at danesheriff.com/Jail (page title: Jail | Dane County Sheriff's Office), phone (608) 266-4311, 210 Martin Luther King Jr. Blvd. Madison, WI 53703, which answered when SearchSystems opened it on September 23, 2026.
That page is the office's jail information page rather than a roster, so a search for a particular person goes through the office at (608) 266-4311.
The Dane County Jail by the Numbers
On an average day in 2025 the jail held about 620 people, down from about 710 in 2019. Its rated capacity in 2025 was 763 beds, and it ran at 82 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.

Who Books People Into the Dane County Jail
The Dane County Sheriff's Office and the agency that reports for Middleton (filed by the FBI as Middleton Police Department) make the arrests that end in a booking in and around Middleton.
The FBI's agency list also places these agencies in Dane County: the University of Wisconsin at Madison (campus police); the Capitol Police (state agency).
The Edgerton Police Department is listed by the FBI across two counties including Dane County, so its arrests are not broken out for Dane County here.
The largest arrest counts reported to the FBI were Madison's 8,274 for 2025, the Dane County Sheriff's Office's 1,739 for 2025 and Blue Mounds's 1,159 for 2025.
Together, the 17 agencies in Dane County with all twelve months of 2025 on file reported 15,821 arrests to the FBI that year. Those kept in custody were booked into the county jail; a person cited and released at the scene was not.
The counts, agency by agency and year by year, are in Middleton arrest records.
From the Jail to State Prison
A sentence of more than a year is served in state prison, not the jail; the Wisconsin Department of Corrections lists its inmates at appsdoc.wi.gov/lop/welcome.
