Finding Someone in Custody in Iowa County
The county jail, run by the Iowa County Sheriff's Office, holds everyone kept in custody after an arrest in Iowa County, from every agency.
SearchSystems opened and checked the jail page of the Iowa County Sheriff's Office at iowacountywi.gov/departments/lecjail (page title: Welcome to the Official Website of Iowa County, WI | Law Enforcement Center | Jail), phone 608-930-9500, 911 Location 109 East Leffler Street Dodgeville, WI 53533, which answered when SearchSystems opened it on September 30, 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 608-930-9500.
