Sheriff William Barnwell said the cuts mark the first time in his 38 years with the department that deputies have not staffed 24-hour shifts.
The county faces a $733,000 deficit and is cutting $345,000 from the Sheriff's Department budget. The cuts took effect Monday.
Barnewell said he is "very concerned" about the impact the cuts will have on public safety. He said he will work with local and state police to cover gaps, but it is becoming much more difficult with fewer police officers on duty.
A 0.6-mill proposal that would generate about $971,000 a year for two years is on the Nov. 6 ballot.
