The Jefferson County Inmate Population
The Jefferson County inmate population is counted first through the local jail, the Jefferson County Correctional Facility in Watertown. That jail is operated by the Jefferson County Sheriff's Office and holds people who are awaiting arraignment, trial, sentencing, transfer, or local jail service. It also holds state-ready prisoners waiting for DOCCS transfer, parole violator holds, civil commitments, and other lawful local commitments. The separate state-prison population in Jefferson County is housed at Cape Vincent Correctional Facility, a DOCCS medium-security prison for sentenced adult males.
The local count changes for practical reasons. New arrests can enter booking through the county jail. Court decisions may release a person, set bail, remand the person, or impose a local sentence. A person sentenced to state prison can remain in Jefferson County jail as state ready until moved to DOCCS. For that reason, the Jefferson County inmate population is not the same thing as a jail roster. The population reports explain size and custody mix, while VINE, Booking/Intake, DOCCS, BOP, and ICE tools answer where one person is held.
The Jefferson County Sheriff's Office page identifies Sheriff Peter R. Barnett and describes a county law enforcement area that includes 1,272 square miles of land and 585 square miles of water. That North Country context matters. Local arrests may come from Watertown, towns and villages, state police, recreation patrol activity near Lake Ontario and the St. Lawrence River, or court warrants. Each path can affect jail intake and daily census.
Jefferson County Inmate Population Statistics
The most useful Jefferson County inmate population numbers come from the New York State Commission of Correction and DCJS jail population reports. The SCOC population statistics page explains that county jails submit daily counts and that monthly and annual average daily census reports are published by facility and custody status. Jefferson County's local jail is also described by the county as a 196-bed direct-supervision facility.
| Measure | Figure | Source / date |
|---|---|---|
| Rated capacity | 196 beds | Jefferson County Correctional Division official page |
| Dormitory-style unit | 36 beds | County facility history, opened 2015 |
| Monthly average daily census | 163 | DCJS/SCOC monthly jail population report, May 2026 |
| Monthly in-house average | 154 | DCJS/SCOC monthly jail population report, May 2026 |
| Boarded out | 9 | DCJS/SCOC monthly jail population report, May 2026 |
| Annual average daily census | 167 | DCJS/SCOC annual jail population report, 2025 |
The distinction between census and in-house population is important. SCOC defines census as the average daily number of people for whom the facility is responsible, whether in house or boarded out. In-house is the physical population at the jail. A reader comparing the May 2026 census to the 196-bed capacity should know that census can include people boarded out, while the in-house figure is a closer measure of physical occupancy.
Jefferson County Jail Population Trends
The Jefferson County inmate population has moved within a fairly narrow range since mid-2025. The May 2026 census was 163, down from 172 in May 2025. That five percent decline was smaller than the statewide jail census decline reported for the same comparison period. The annual trend shows a longer story: 2025 was close to 2024 and 2018, higher than the pandemic-era low, and still below the 2017 high.
| Year | ADP / census | Notes |
|---|---|---|
| 2016 | 177 | DCJS/SCOC annual report baseline in research table. |
| 2017 | 185 | Highest annual figure in the 2016-2025 table. |
| 2019 | 129 | Decline before the COVID-era low period. |
| 2020 | 102 | Lowest annual figure in the table. |
| 2024 | 166 | Near the 2025 level. |
| 2025 | 167 | Up one percent from 2024 and down six percent from 2016. |
Monthly reports add custody detail. In May 2026, Jefferson County had 15 sentenced jail inmates, 3 technical parole violators, 2 state readies, 134 other unsentenced people, no civil average, and no federal average in the in-house categories. State readies fell sharply from 33 in May 2025 to 2 in May 2026, while other unsentenced people rose from 102 to 134. That shift shows why a single total count does not tell the whole jail story.
Who Makes Up Jefferson County Inmates
Most of the May 2026 in-house Jefferson County inmate population fell into the other unsentenced category. DCJS/SCOC uses that category for people awaiting arraignment, trial, or sentencing and for parole violators held on new arrest charges. Sentenced jail inmates were a much smaller part of the local population, and state-ready prisoners were a small count by May 2026. Sex, age, race, felony/misdemeanor split, and average length of stay were not located in the official sources reviewed, so those percentages should not be assumed.
- Other unsentenced
- People awaiting arraignment, trial, or sentencing, plus certain parole violators with new charges.
- State ready
- A person sentenced to state prison but still waiting in county jail for DOCCS transfer.
- Technical parole violator
- A person held on a parole violation warrant that may not be based on a new conviction.
- Boarded out
- A person for whom Jefferson County is responsible but who is housed outside the facility.
Jefferson County Jail Capacity
The county's official correctional division page describes the Jefferson County Correctional Facility as a 196-bed direct-supervision jail that opened in 1992. It has six pods, each able to hold up to 32 inmates, and one officer works inside each pod. In 2015, the county opened a 36-bed dormitory-style housing unit in the former indoor recreation area, with 18 double bunks and six six-person tables in the day area. The county frames that dormitory as incentive housing for good behavior.
For May 2026, the average in-house population of 154 was about 79 percent of rated capacity. The census responsibility of 163 was about 83 percent of rated capacity if compared to beds, but that comparison is less direct because census includes boarded-out people. April 2026 was higher, with a 177 census and 163 in house, still below the 196-bed capacity. Those figures support a careful capacity note, not a claim that crowding can never occur.
Laws Governing Jefferson County Jail Data
New York law makes many agency records available while also requiring redaction or withholding for protected records. The Jefferson County inmate population data is published through SCOC/DCJS jail reports, while individual booking, custody, and court records must be requested from the correct custodian. The county FOIL portal also warns that court files are not maintained by county agencies and must go to the proper court clerk or county clerk.
Key access rules:
New York Public Officers Law Section 87 requires agency records to be available unless an exemption permits withholding or redaction.
New York Civil Rights Law Section 50-b protects identifying information of sex-offense victims, including photographs and court files.
Criminal Procedure Law Section 160.50 requires sealing when a criminal action ends in favor of the accused, unless an exception applies.
SCOC minimum standards govern local correctional facilities and police lockups in New York.
Search Jefferson County Inmate Population
The official county-jail search path is not a Jefferson County Sheriff's Office mugshot roster. The research located county and state sources pointing to VINE/VINELink for custody status and notification, plus Booking/Intake for immediate confirmation. Start with VINELink, select New York, and search for the person in county jail custody. If a recent arrest is not visible yet, call Booking/Intake at (315) 786-2688 because a new booking may still be in processing or classification.
- Search VINELink for New York county jail custody status.
- Register separately for custody and court-event notifications if the person is found.
- Use the four-digit PIN process described by Jefferson County VINE for phone alerts.
- Call Booking/Intake if a new arrest is not visible or status must be confirmed quickly.
- Use DOCCS, BOP, or ICE locators if the person is no longer in local jail custody.
Jefferson County's own VINE page cautions users not to depend on VINE or any one service for protection. That warning is worth keeping. VINE is a custody and court-event notification service, not a full booking record, not a court docket, and not a public mugshot gallery.
The Jefferson County Sheriff's Office homepage is shown in the image below, which comes from the official county source at the Sheriff's Office page.
The sheriff source helps connect the jail population to the operator, while current custody status still routes through VINE and Booking/Intake.
Jefferson County Roster Search Fields
VINELink could not be fully field-inspected in static capture because the portal relies on live JavaScript. The Jefferson County and SCOC sources still support a careful field table. The county-jail search should be described as a New York VINE custody-status search, not as a county-hosted booking-profile system with fields that were not captured.
| Field label | Type | Required | Notes |
|---|---|---|---|
| State / location | Selection | Unspecified | Use New York for Jefferson County county-jail custody. |
| Name | Text | Unspecified | Used to locate the suspect or offender in VINE. |
| Offender ID / custody identifier | Text | Unspecified | Exact New York labels were not visible in static capture. |
| Registration phone number | Phone | Required for alerts | Used for custody and court-event notification. |
| Four-digit PIN | Numeric | Required for alerts | Initial PIN is the last four digits of the registered phone number. |
Jefferson County Jail vs State Prison
People often search the wrong system. A person arrested in Jefferson County usually enters the Jefferson County Correctional Facility if not released by appearance ticket, bail, or court order. A person who receives a state-prison sentence can later move to DOCCS custody, including Cape Vincent Correctional Facility or another New York prison. Federal and immigration custody are separate again.
| Custody type | Who it covers | Where to search |
|---|---|---|
| County jail | Pretrial detainees, local sentences, holds, state-ready prisoners | VINELink or Booking/Intake |
| State prison | Sentenced adult state prisoners | DOCCS Incarcerated Lookup |
| Federal prison | People in BOP custody from 1982 to present | BOP inmate locator |
| ICE custody | Immigration detainees | ICE Online Detainee Locator |
Past Jefferson County Inmate Records
Released or older Jefferson County inmate records may not appear in VINE. For local booking records, report copies, or records not online, use the Sheriff's Records Division or the Jefferson County FOIL process. The Records Division page says conviction-only background checks are walk-in, cost $10, and require valid photo ID or a notarized release. Report copies are $0.25 per page, and fingerprinting is offered on Wednesdays from 8:00 a.m. to 10:45 a.m. for $5.
The county FOIL page is shown below from Jefferson County's FOIL request portal.
The FOIL route is useful for county agency records, but not for official court files. Court records after a jail arrest must be requested from the relevant court clerk or searched through court systems when available.
Jefferson County Detention Facilities
Two active detention facilities appear in the Jefferson County facility map. They serve different populations and use different lookup systems, so the facility name matters before a search begins.
- Jefferson County Correctional Facility - the county jail for pretrial detainees, local sentences, state-ready holds, parole violator holds, and other county-jail commitments.
- Cape Vincent Correctional Facility - a New York DOCCS medium-security state prison for sentenced adult males.
