The Fairbanks District Office provides supervision for felony offenders who are on probation and/or parole. The office is responsible for a geographic area extending from the Alaska Range to the Brooks Range, including the Tanana and Yukon River watersheds - over 37% of Alaska and an area greater than the size of California, the Nation's third largest state. Additionally, the Fairbanks District Office supports the other regional offices in Bethel, Nome, Kotzebue, and Utqiagvik with training, manning, and coverage of multiple rural caseloads from outside the geographic area listed above in Western Alaska. The majority (well over 60%) of the probation district's approximately 500 supervised offenders live within the Fairbanks metropolitan area. The probation district contains a total of more than 40 communities, with populations ranging in size from approximately 32,500 (Fairbanks) to fewer than 10 (e.g., Kallands). Many of the communities are fly-in only, with no road connection. The office also supervises offenders who reside along the rural roads system, which is located South from Fairbanks on the Richardson Highway to the Canadian Border, South on the Parks Highway to Cantwell, North of Fairbanks to the Brooks Mountain Range and West to Kaltag.
