Every year Lake County law enforcement agencies arrest and detain 840 offenders, and maintain an average of 42 inmates (county-wide) in their custody on any given day.
The weekly turnover rate of inmates is approximately 55%, meaning that every week more than half of these inmates are released and then replaced with new offenders being booked into jail.
The charts below break down the men, women, races, ethnicities and the types of crimes that people are arrested and incarcerated for in both Lake County and state prisons throughout the country. This information is compiled from local police and the Lake County Sheriff's Department, as well as the state of Montana and the United States Department of Justice and Census Bureau.
