Tuolumne County Inmate Population Overview
The local jail part of the Tuolumne County inmate population is reported to the BSCC Jail Profile Survey public query by the Tuolumne Sheriff's Dept. That count covers the adult local detention population at the John H. "Jack" Dambacher Detention Center, not people already serving California Department of Corrections and Rehabilitation sentences at Sierra Conservation Center. It includes people awaiting court, people serving county jail terms, and people booked on felony, misdemeanor, or civil authority.
The Tuolumne County inmate population changed sharply after the current Dambacher facility opened. BSCC data show average daily population rising from 73.08 in 2021 to 142.67 in 2024, then easing to 134.75 in 2025 while annual bookings rose to 2,650. Those numbers should be read with the county's rural scale in mind. Census QuickFacts listed a 2020 population of 55,620, so a jail average near 135 people is a visible public-safety and court-system measure for a small, spread-out county.
Tuolumne County Inmate Population Statistics
The strongest jail-population source is the BSCC query, which the state describes as county-reported jail data screened by BSCC. The Dambacher Detention Center capacity is less clean. County procurement and Grand Jury materials use 230 inmates, while a sheriff jail deputy recruitment PDF says the facility holds up to 240. Because the RFP and Grand Jury reports agree on 230, that figure is the better main capacity number, with the 240 figure kept as an official conflict.
| Measure | Figure | Source / Year |
|---|---|---|
| County jail reporting agency | Tuolumne Sheriff's Dept. | BSCC JPS, 2025 |
| Average daily population | 134.75 | BSCC monthly data, 2025 |
| Annual bookings | 2,650 | BSCC monthly booked totals, 2025 |
| Highest one-day population | 158 max monthly high | BSCC JPS, 2025 |
| Federal contract housing ADP | 0.0 | BSCC JPS, 2025 |
| State contract housing ADP | 0.0 | BSCC JPS, 2025 |
| Approximate local jail rate | About 242 per 100,000 residents | BSCC 2025 ADP and 2020 Census |
The local rate is higher than the national jail incarceration rate of 198 per 100,000 U.S. residents reported by the Bureau of Justice Statistics for midyear 2023. That comparison is approximate because it pairs Tuolumne's 2025 average with a 2020 Census base, but it still gives scale to the county jail count.
Tuolumne County Inmate Population Trends
Recent Tuolumne County inmate population trends show a rebound from the 2021 low, followed by a small drop in 2025. Bookings did not fall with the average population. They climbed from 2,373 in 2024 to 2,650 in 2025, which suggests more jail admissions but shorter stays, different release timing, or a changing mix of cases. Mental-health indicators also rose over the five-year pull, with open mental-health cases averaging 84.00 in 2025 and psychotropic-medication counts averaging 59.58.
| Year | ADP | Bookings | Highest One-Day Pop | Mental-Health Cases Avg |
|---|---|---|---|---|
| 2021 | 73.08 | 2,177 | 134 | 30.25 |
| 2022 | 101.67 | 2,233 | 149 | 55.00 |
| 2023 | 124.67 | 2,268 | 170 | 64.33 |
| 2024 | 142.67 | 2,373 | 168 | 87.00 |
| 2025 | 134.75 | 2,650 | 158 | 84.00 |
Who Is in Tuolumne County Jail
The 2025 monthly breakdown shows the Dambacher jail population was mostly nonsentenced, which means people held before conviction, before sentencing, or while a case or warrant is pending. In December 2025, for example, the monthly ADP was 148, with 76 nonsentenced male, 33 nonsentenced female, 27 sentenced male, and 12 sentenced female people reported. Earlier Vera data for 2021 also estimated that 80 percent of the jail population was pretrial, with 70 percent of arrests classified as misdemeanors.
- Pretrial custody: people held after arrest, on warrants, or while court proceedings continue.
- Sentenced local custody: people serving jail terms or local commitments rather than CDCR prison sentences.
- Mental-health needs: BSCC averages show open mental-health cases increased from about 30 in 2021 to 84 in 2025.
- Contract housing: federal, state, and other contract bed averages were reported as 0.0 in 2025.
Those categories matter for lookup. A person booked yesterday may be tied to the sheriff, jail, and court. A person sentenced to state prison moves out of the local jail count and into the CDCR system.
Tuolumne County Inmate Population Laws
California law shapes how Tuolumne County inmate population data, booking information, and jail conditions become public. The law does not require every record to appear in a public web roster, but it does require access to nonexempt public records and specific arrest information. Safety, juvenile, medical, open-investigation, and prosecution limits can still apply.
Key Statutes:
Government Code section 7922.525 makes nonexempt public records open for inspection during agency office hours.
Government Code section 7922.535 sets the usual 10-day agency determination period for copy requests.
Government Code section 7923.610 requires release of specified arrest and booking information unless an exception applies.
15 CCR section 1040 requires monthly average daily population accounting for local detention data reported to BSCC.
Penal Code section 6030 also authorizes minimum standards for local detention facilities. Those standards explain why jail population data is not just a head count. It connects to health care, classification, housing, safety, training, programs, and death-in-custody review.
Search Tuolumne County Inmates
The most important local lookup point is also the easiest place to make a mistake. The sheriff-linked Citizen RIMS public safety portal is not configured as a full current-inmate roster. Research found arrests enabled, but inmates disabled. Arrest photos and inmate photos were also disabled, and the portal warns that arrest entries do not reflect every arrest in the county. Use it for recent arrest and public-safety data, then verify current custody through the sheriff's office.
The official custody-status phone number listed through the court is 209-533-5844. The official Custody Division page also lists 209-533-7270 for general jail information. If a record is not online, the Sheriff's Records Section can process allowed criminal and custody record requests under the California Public Records Act and local release rules.
- Open the sheriff-linked Citizen RIMS portal and check recent arrest data when the module is available.
- Search by first or last name, but treat a missing result as inconclusive.
- Call 209-533-5844 when the question is current custody at the Tuolumne County jail.
- Use Sheriff Records for older booking or custody records that are not shown online.
- Search CDCR CIRIS, BOP, ICE ODLS, or VINELink when local custody does not explain the person's status.
The manifest image below comes from the officially linked Citizen RIMS portal, the public-safety system that should be treated as an arrest channel rather than a full jail roster.
The portal image reinforces the key local point: a Tuolumne County custody search needs the portal, the jail phone line, and records requests because the current-inmate module is not enabled.
Tuolumne County Arrest Search Fields
The Citizen RIMS arrest interface exposed only a partial field inventory. No public current-inmate search-field table was captured because the inmate module was disabled. That is why the Tuolumne County inmate population lookup should not be described like a standard jail roster with housing, bond, and mugshot profile fields.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| First | Text | Unspecified | Observed for arrests or person search; minimum characters not published. |
| Last | Text | Unspecified | Likely supports last-name or partial-name searching, exact rules not published. |
| Options toggle | Icon/button | Optional | Show or hide options control observed in the interface. |
| Search button | Icon/button | Unspecified | Material-style button present in the app bundle. |
| Clear/reset button | Icon/button | Unspecified | Reset control present, exact label not exposed. |
Tuolumne County Inmate Records
Public arrest entries are much narrower than internal booking records. Citizen RIMS public arrest data may show name, occupation, incident number, case number, and charges, but research did not confirm public age, date of birth, housing, bond by charge, or a photo field. The Custody Manual describes a far broader internal booking and admission record that may include identifiers, arrest and admission times, legal authority for confinement, photographs, fingerprints, medical screening, property, and emergency contact data.
| Record Area | What It Can Show |
|---|---|
| Public arrest view | Name, occupation, incident number, case number, and charges when an arrest entry is available. |
| Booking/admission record | Booking number, arrest time, admission time, legal authority, warrants, and court of jurisdiction. |
| Identification | Aliases, physical description, photo, fingerprints, marks, scars, tattoos, and government ID fields. |
| Screening | Medical, dental, mental-health, suicide-risk, special-needs, and classification information. |
| Property and calls | Property inventory, money, receipt, and booking phone-call record or opportunity to call. |
County Jail or State Prison
A Tuolumne County inmate population search must separate pretrial jail custody from prison custody. The Dambacher Detention Center is run by the sheriff and holds local jail inmates. Sierra Conservation Center is a CDCR state prison in Jamestown and is searched through CDCR CIRIS, not through the sheriff. Federal sentenced prisoners are searched through BOP, while immigration detainee searches use ICE ODLS.
| Custody Type | Correct Search Channel | Local Meaning |
|---|---|---|
| Pretrial or local jail | Sheriff custody phone, Citizen RIMS arrests, Sheriff Records | Dambacher Detention Center population. |
| Sentenced state prison | CDCR CIRIS | Sierra Conservation Center and other CDCR institutions. |
| Federal sentence | BOP inmate locator | No BOP facility was located in Tuolumne County. |
| Immigration custody | ICE ODLS | No ICE detention facility was located in Tuolumne County. |
The CDCR CIRIS locator is the right search path for people moved from local custody into state prison after sentencing.
That locator matters locally because Sierra Conservation Center is inside Tuolumne County but outside the sheriff's jail roster and records workflow.
Tuolumne County Detention Facilities
The adult detention map has one main county jail and one state prison physically in the county. These facilities serve different populations, use different lookup tools, and follow different visitation and mail rules.
- John H. "Jack" Dambacher Detention Center is the Tuolumne County jail for pretrial, sentenced local, felony, misdemeanor, civil, and all-gender adult custody.
- Sierra Conservation Center is a CDCR state prison for sentenced incarcerated people, with conservation and fire-camp training duties.
Tuolumne County Jail Conditions
Official custody materials list Alcoholics Anonymous, Bible Study, GED training, Law Library, and Narcotics Anonymous. The Custody Manual adds social services, faith-based services, recreation, library access, education or vocational training, drug and alcohol recovery, and reentry support within 30 days of release. County Behavioral Health also notes 24/7 crisis services and on-site jail evaluations and services.
Grand Jury reports add useful context. The 2022-2023 report described kitchen, laundry, library, medical, and education areas as clean and organized, while also noting staffing shortages and programs not running at full capacity. A 2024-2025 detention-facilities report summary said DDC, Sierra Conservation Center, and juvenile detention facilities were clean, generally in good condition, operating within BSCC or state guidelines, and providing access to medical, dental, mental-health care, and rehabilitation programs.
Tuolumne County Mobile Custody Access
Tuolumne County's TC Connect app is another local channel, but it should be described carefully. The official county page and the Google Play listing for TC Connect advertise an In Custody Services applet. Research did not verify the in-app fields, so the app should be used as a possible path alongside Citizen RIMS, the jail phone line, Sheriff Records, and VINELink, not as proof of a full app-only jail roster.
Note: A missing web result is not proof that a person is out of custody in Tuolumne County.

Where are sentenced state prisoners searched?
Sentenced people in CDCR custody, including those at Sierra Conservation Center, are searched through CDCR CIRIS. The county jail channels cover local jail custody, not state prison custody.
Does Tuolumne County publish jail mugshots?
No official public county roster mugshot display was located. Booking photos are taken internally during admission, but public access depends on records-request rules and California law.
