The Sierra County Inmate Population
The Sierra County inmate population is best read as a custody-routing picture, not as a single jail count. The Sierra County Temporary Housing Facility page says the former county jail now operates as a temporary holding facility. The same county source says Sierra County inmates are housed mainly at Wayne Brown Correctional Facility in Nevada County and sometimes at Plumas County Jail. That means the person may be arrested by the Sierra County Sheriff-Coroner, booked or held briefly in Downieville, and then housed outside the county while the court case remains in Sierra Superior Court.
The current Sierra County inmate population is also shaped by the small size and mountain geography of the county. The U.S. Census QuickFacts profile estimated 3,098 residents in 2025 across 953.17 square miles. In a county that small, a few bookings or jail days can change local rates. Capacity, admissions, and average daily population must be read with care because Sierra no longer runs a full Type II jail for normal ongoing custody.
Sierra County Inmate Population Statistics
The clearest current figure is the absence of a full county jail. Vera's Sierra County fact sheet reported 0 county jails, 0 state prisons, and 0 juvenile facilities in 2021. It also reported 0 people in county jails on an average day, 0 jail admissions, 63 arrests, and 6 people from Sierra County in state prison. Those figures do not mean no one can be arrested in Sierra County. They reflect the county's post-2015 operating model, where local custody begins in temporary holding and many jail beds are purchased from another county.

Sierra County Jail Population Trends
Historic Sierra County inmate population figures show small average daily counts before the full jail stopped ordinary operations. A Sierra probation and community corrections packet listed annual bookings and average daily population from 2006 through the first year after the 2015 change. The numbers are modest in raw form, but they matter locally because the county now pays another county for many custody days.
| Year | Bookings | Total Jail ADP | Context |
|---|---|---|---|
| 2006 | 202 | 10 | Pre-closure local jail operations |
| 2010 | 154 | 6 | Small local jail population |
| 2014 | 120 | 6 | Last full year before the 2015 status change |
| 2015-16 | 80 | 4 | After Nevada County housing began |
The same research packet reported that Wayne Brown processed 69 Sierra County inmates in 2015 for 1,274 custody days at a cost of $98,314.58. For January through March 2016, it listed 20 inmates, 297 custody days, and $22,919.49 in cost. The later 2025 board item raised the daily housing rate to $140 per inmate day, which makes contract demand a central population issue for Sierra County.
Who Makes Up Sierra County Custody
BSCC demographic reference data for the last pre-closure years show how small and variable the Sierra County inmate population was while local jail operations still existed. In 2014, the total average daily population was 5.6, with 4.5 male ADP, 1.2 female ADP, 3.8 unsentenced ADP, and 1.8 sentenced ADP. In 2015, the reported total ADP dropped to 0.3 after the March change. Those figures should not be stretched into current capacity claims because the county's facility role changed.
- Pretrial custody often means a Sierra arrest followed by temporary holding and housing at Wayne Brown.
- Sentenced local jail time is generally served through the contracted jail arrangement when accepted by Nevada County.
- State prison custody means CDCR, not the Sierra temporary holding facility or a county roster.
- Federal or immigration custody uses federal systems when a case leaves local custody.
Sierra County Jail Capacity
Rated capacity is not the right current headline for Sierra County. The full Type II jail closed in 2015, and the public Sierra page now describes temporary holding plus contract housing. No current official source in the research published a temporary holding capacity. A capacity number should not be added from third-party jail directories. The local issue is not crowding in a large Sierra cell block. It is whether Sierra can book, hold, transfer, and pay for custody through other facilities.
The 2024 Sierra County Grand Jury final report stated that Sierra County does not have a jail and uses a daytime holding facility in the Sheriff's Office. The 2025 jail-services agreement item said Sierra has not operated a jail facility since 2015 and has housed inmates under agreement with Nevada County since then. That official language is the strongest way to describe current capacity.
Laws Governing Sierra County Inmate Records
California law provides the access framework, while Sierra's local process decides where a request starts. The California Public Records Act is the baseline public-records law. The 10-day agency determination rule explains why agencies may take time to decide whether records can be released. Law-enforcement and correctional records may be limited under California's investigatory-file exemption, especially when a case is active.
Key Statutes:
Penal Code sections 6030 and 6031 support statewide standards and inspections for local detention facilities.
Penal Code section 10008 requires agencies to post specified death-in-custody information online.
Penal Code section 851.5 supports the rule that booked arrestees receive completed phone calls.
Sierra County State Prison Population
People from Sierra County who receive a state-prison sentence move into the California Department of Corrections and Rehabilitation CIRIS locator. CIRIS is not a jail booking list. CA.gov says CIRIS results may include name, CDCR number, age, current location, commitment counties, admission date, and Board of Parole Hearing information. A missing Sierra or Nevada roster result can be normal after a person is transferred to CDCR.
No CDCR adult prison was identified inside Sierra County. The Sierra Conservation Center can cause confusion because of its name, but CDCR places that prison in Jamestown, Tuolumne County. For the Sierra County inmate population, the useful distinction is location versus county of commitment. A state prisoner may have Sierra as a commitment county without being housed in Sierra County.
Search the Sierra County Inmate Population
A Sierra County inmate search should start with custody stage. If the arrest is recent or the destination is unknown, call the Sierra County Sheriff-Coroner. If the person has been sent to the primary contracted jail, use Nevada County's in-custody report. If that search fails, ask whether Plumas County is involved. For release notice, register with VINE. For filed charges, use Sierra Superior Court. For prison, federal, or immigration custody, use the separate statewide or federal locators.
- Confirm whether the person is newly arrested, already housed, released, or sentenced.
- Call Sierra Sheriff at 530-289-3700 when the location is uncertain.
- Search the Nevada County in-custody report if Wayne Brown may be holding the person.
- Call Plumas County Correctional Facility if Sierra or Nevada says the person was routed there.
- Use CDCR, BOP, or ICE only when that custody type fits the case.
Sierra County Current Inmate Lookup
Sierra County does not publish a Sierra-hosted current jail roster in the official sheriff pages reviewed. The county's own custody page points users to Nevada County for people housed at Wayne Brown. The Nevada report is useful, but it is not a Sierra-owned database and it does not show every booking detail. It confirms name, booking date, sex, visiting-window categories, and a VINE release-notification link in the public capture.
The Sierra Temporary Housing Facility page is the source for the local custody structure, while the linked Nevada roster is the practical online list for many current Sierra detainees housed outside the county.
The screenshot helps show why Sierra County inmate lookup depends on the county's temporary-holding notice and regional housing directions, not a normal local jail roster.

Sierra County Past Inmate Records
Released or older Sierra County inmate records usually require a records request or a court request. The Nevada current-custody report is not an archive. Sierra Sheriff says to allow at least 10 business days after an incident before requesting records. The local records page lists a $40 report fee plus $0.25 for each page after 20 pages, and active criminal cases under investigation, DA review, or court action are referred to the District Attorney for release decisions.
The Sierra Sheriff records request page is the local path for incident reports and some booking-related records. Filed charges, complaints, pleas, and dispositions belong with Sierra Superior Court. A person can be in a Nevada County jail bed while the court record still belongs to Sierra Superior Court.
What Sierra County Inmate Records Show
The public Nevada County report linked for many Sierra inmates is a custody confirmation tool, not a full booking packet. It did not show mugshots, charges, bail, a booking number, housing unit, arresting agency, court date, or release date in the captured public view. Those details may exist in internal booking, court, or records systems, but they are not all placed on the public roster.
| Field | What It Shows |
|---|---|
| Full Name | The person listed in custody, shown last name first. |
| Book Date | The date entered into custody on the Nevada report. |
| Sex | M/F value in the public result table. |
| Visiting Hours | Tuesday and Thursday or Wednesday and Friday windows, or no-current-visiting messages. |
| VINE Release Notification | A link to register for release notice. |
| Charges and Bail | Not shown in the public Nevada capture; use facility or Sierra court channels. |
Sierra County Jail vs Prison Search
One search cannot cover every custody type. The Sierra County inmate population may involve local arrest, contract jail housing, state prison, federal prison, immigration detention, or release. The right tool depends on who has legal and physical custody at that moment.
| Custody Type | Where to Look | Best Use |
|---|---|---|
| Recent Sierra arrest | Sierra Sheriff-Coroner | Confirm temporary holding, release, Wayne Brown, or Plumas routing. |
| County jail housing | Nevada County in-custody report | Find many current Sierra inmates housed at Wayne Brown. |
| State prison | CDCR CIRIS | Locate sentenced people in California prison custody. |
| Federal prison | BOP inmate locator | Search federal prisoners from 1982 to present. |
| Immigration detention | ICE ODLS | Search current ICE custody with A-number or exact biographic details. |
Sierra County Detention Facilities
The local facility map has three practical stops. The Downieville facility starts the local custody process. Wayne Brown is the primary contracted jail. Plumas is an occasional contracted fallback. No state prison, BOP facility, ICE facility, or city jail was identified inside Sierra County.
- Sierra County Temporary Holding Facility is the local booking and temporary holding point, not a full public roster jail.
- Wayne Brown Correctional Facility is the primary Nevada County jail facility used for many Sierra County inmates.
- Plumas County Correctional Facility is an occasional housing destination when Sierra routes someone there.
Sierra County VINE Notifications
Sierra County participates in VINE for custody-status notification. The county's VINE page says VINELink lets crime victims and concerned citizens obtain custody-status information and register for notifications by phone, email, text, or TTY. It also says Sierra County is an active participant and that the Sheriff's Office updates the information every 15 minutes.
The Sierra County VINE page is useful after a current custody result appears or when release notice matters more than a full booking profile.
VINE is a notification channel, not a court docket and not a substitute for the correct jail or CDCR locator.
Sierra County Inmate Population FAQ
Does Sierra County have a normal jail roster?
No Sierra-hosted roster was located in the official sheriff pages reviewed. Sierra directs users to Nevada County's in-custody report for people housed at Wayne Brown, while recent arrests may still require a Sierra Sheriff phone confirmation.
Why does Vera report 0 county jails?
Vera's 2021 fact sheet reflects the fact that Sierra County does not operate a full county jail. People may still be arrested, booked, held for a short time, transferred, housed under contract, released, or later sentenced to CDCR.
Where are most Sierra County inmates housed?
Sierra's own custody page says inmates are housed primarily at Wayne Brown Correctional Facility in Nevada County and occasionally at Plumas County Jail. The first step is to confirm the actual custody location before trying to visit, send mail, or request details.
Can a Sierra case be in court while the person is in Nevada County?
Yes. The jail bed and court case can be in different counties. Sierra Superior Court handles filed Sierra charges even when Wayne Brown or Plumas is the physical housing facility.
