The Sweetwater Co Jail is a detention center located at 50140 Hwy 191 S Rock Springs, WY which is operated locally by the Sweetwater County Sheriff's Office and holds inmates awaiting trial or sentencing or both. Most of the sentenced inmates are here for less than two years. Sweetwater County accepts inmates from surrounding towns, Rock Springs Police Department, and the US Marshal's Service.

New detainees arrive at the jail regularly, with some being released on bail, placed under pretrial services caseloads, supervised by probation agencies, or released on recognizance with a court appearance agreement. Those who are not released await their court appearances at the jail, receiving accommodations including bedding and meals.

The Sweetwater County Detention Center in Rock Springs, Wyoming, is a county-operated correctional facility that houses ICE detainees under contract with the U.S. Department of Homeland Security and Immigration and Customs Enforcement. Located in southwestern Wyoming along the Interstate 80 corridor, the detention center primarily serves local criminal detention needs while also functioning as a regional federal detention partner for ICE and other federal agencies. The facility houses pretrial detainees, sentenced inmates, federal prisoners in transit, and immigration detainees awaiting transfer, court proceedings, or removal actions. Because of its centralized location between Denver, Salt Lake City, and western energy-producing regions, the jail has become an important detention and transportation hub within Wyoming’s correctional system.

The detention center maintains a rated capacity of 211 inmates, with county officials describing it as one of the more advanced county correctional facilities in Wyoming. Built in 2005, the jail includes secure housing pods, medical services, transportation staging areas, booking and intake systems, attorney visitation areas, control room operations, and a separate juvenile detention section, a feature only a handful of county facilities in Wyoming possess. The jail routinely handles inmates transferred from other parts of the state and occasionally from out of state, giving the facility a broader operational footprint than many rural county jails.

ICE Detainee Information

This facility holds immigration detainees under an active contract with U.S. Immigration and Customs Enforcement in addition to its regular population. ICE detainees are civil immigration detainees, not criminal defendants, and are held while their immigration cases are processed. The rules, rights, and services that apply to ICE detainees differ from those that apply to the general jail population.

To locate an ICE detainee at this facility, use the ICE Online Detainee Locator at locator.ice.gov. You will need the detainee's A-Number, a nine-digit Alien Registration Number that appears on any immigration document they have received. If the A-Number has fewer than nine digits, add zeros at the beginning. If you do not have the A-Number, you can search using the detainee's full legal name, country of birth, and date of birth. Names must be an exact match; try variations if the first search returns no results.

Immigration bond works differently from criminal bail. Not all detainees are eligible for bond; those with certain criminal convictions or prior deportation orders may be subject to mandatory detention. For those who are eligible, bond is set by an immigration judge and typically ranges from $1,500 to over $10,000. Bond must be paid in full before release. An immigration attorney can request a bond hearing and argue for a lower amount based on the detainee's circumstances.

Unlike criminal defendants, ICE detainees do not have the right to a government-appointed attorney. They must hire a private immigration attorney or find free legal help through a nonprofit organization. RAICES provides legal services and bond assistance at raicestexas.org. The National Immigrant Justice Center offers free legal representation at immigrantjustice.org. Many immigration courts also maintain a list of free and low-cost legal service providers available to detainees upon request.

ICE transfers detainees between facilities frequently and with little advance notice, sometimes to locations far from family and legal counsel. If you cannot locate your family member through this page, search the ICE Online Detainee Locator again at locator.ice.gov with their A-Number. If they have an attorney, notify the attorney immediately as transfers affect court appearances and case timelines.

The facility operates under the authority of the Sweetwater County Sheriff’s Office, currently led by Sheriff John Grossnickle. Sheriff Grossnickle has publicly supported expanded cooperation with federal immigration authorities, including additional ICE coordination initiatives tied to immigration enforcement operations. In 2025, the sheriff’s office announced development of a localized ICE task force partnership intended to strengthen federal immigration enforcement coordination throughout the region. Federal detention agreements involving ICE provide supplemental operational revenue to the county while helping federal agencies maintain detention capacity in the Rocky Mountain region.

Unlike the massive privately operated immigration detention complexes found in Texas, Louisiana, and Georgia, the Sweetwater County Detention Center functions primarily as a traditional county jail with supplemental federal detention capabilities. This creates a considerably different detention environment than stand-alone ICE detention compounds specifically built for large-scale immigration detention. ICE detainees housed at Sweetwater are generally held temporarily before transfer to larger regional facilities or immigration court jurisdictions. The jail’s modern infrastructure, transportation access, and ability to separate detainees by classification make it operationally valuable for DHS detention logistics throughout Wyoming and neighboring states.

The Sweetwater County Detention Center continues serving as one of Wyoming’s most significant county correctional facilities while remaining part of ICE’s broader detention network across the western United States. The jail’s secure design, modern operational systems, and established federal detention agreements allow ICE and other federal agencies to utilize the facility for temporary detention and inmate transfer operations. As immigration enforcement activity continues evolving nationwide, county facilities like Sweetwater increasingly play a larger role in supporting federal detention infrastructure beyond the southern border states traditionally associated with ICE detention operations.

Inmate Locator

Finding an Inmate at Sweetwater County Detention Center (ICE)

If you're trying to locate someone in custody at Sweetwater County Detention Center (ICE) in Rock Springs, Wyoming, the fastest path depends on how recently the arrest happened, what type of facility holds the inmate, and how quickly that facility updates its public records. There is no single nationwide inmate database that covers every detention facility in real time, so locating a specific person often means checking multiple sources or calling Sweetwater County Detention Center (ICE) directly at 307-352-4900.

Using the InmateAid Inmate Search

The InmateAid inmate search is the fastest starting point for locating someone at Sweetwater County Detention Center (ICE). The search pulls from facility rosters, booking systems, and arrest record databases to return current custody status, charges, and housing facility. If the person was arrested or transferred recently and doesn't appear yet, the facility likely hasn't updated its public roster, which can lag by hours or a full business day. Try again later or call 307-352-4900 to confirm.

When the Inmate Doesn't Appear in the Search

Several explanations are possible if a person isn't showing up. The booking may not be complete. The person may have been released, transferred to another facility, or moved to federal or immigration custody. Some facilities deliberately delay public records by 24 to 72 hours for security reasons. Minors are never published in any public locator regardless of facility. To rule out a transfer or release, call 307-352-4900 and ask the booking desk to confirm current status.

What You'll Need to Search Effectively

Have ready: full legal name and any aliases, date of birth, and approximate date of arrest. If you know which agency made the arrest, that narrows results significantly. A booking number locates the record immediately. Without at least a full name and approximate date, searches return too many results to be useful.

Once You've Located the Inmate

When you confirm the person is at Sweetwater County Detention Center (ICE), set up a prepaid phone account so you don't miss the first call, and arrange any money transfer or commissary funding needed. For phone discount plans, money transfer, and mail services available at Sweetwater County Detention Center (ICE), see InmateAid's inmate services and call 307-352-4900.

To confirm current custody status, recent transfers, or release information at Sweetwater County Detention Center (ICE), call 307-352-4900.
