The minimum compensation for sheriffs is set by Tennessee Code Annotated § 8-24-102, and is based on county population. The minimum salary of the sheriff is 10 percent greater than the salary of county general officers such as the trustee.
For counties with 50,000-64,999 people (Putnam County's current category, using the 2000 census), the minimum salary is $76,407 for fiscal year 2010-2011.
If the census rises, the salary rises accordingly. For instance, if the 2010 census shows Putnam County with a population of 65,000-99,000, the salary would likely be closer to $79,436.
