Official Lyon County Contacts
The Lyon County Sheriff’s Department is at 410 S. Boone St., Rock Rapids, IA 51246. Call the main office and non-emergency dispatch at 712-472-8300, or call the Lyon County Jail at 712-472-8356. The department also lists sheriff@lyoncountyia.com and fax 712-472-2303. The research does not publish records-office business hours, so call before making an in-person records visit.
Choose the source that matches the record or custody stage:
- For a local booking photo or arrest record, use the county records hub and its request steps.
- For a possible warrant, consult the sheriff’s warrant list and confirm it through the Most Wanted page’s official check path.
- For a recent arrest or release, compare the current-inmate PDF with the roughly 30-day arrest press log.
- For current custody, call the Lyon County Jail when the time-stamped roster is unclear.
- For a sentenced state prisoner, use the Iowa Department of Corrections offender search.
- For federal custody, use the Bureau of Prisons locator; immigration custody has a separate ICE locator.
