The county started the month with 1,319 cases, which steadily dropped to 1,085 active cases as of Aug. 31, according to the TDH. While cases did not decline each day, the area saw an overall decrease.
In the last week alone, active cases have declined by 9%.
Totals from Aug. 31 show the county is at its lowest point in weeks after the area saw a peak of 1,545 cases in mid-July.

The data comes just two days after Williamson County opted to let its countywide mask mandate expire. It is not yet clear what effect this may have on active case numbers.
In an announcement Aug. 29, County Mayor Rogers Anderson said many citizens have stated they will wear face masks voluntarily.
Schools in the county, including in Williamson County Schools and Franklin Special School District, are continuing to require masks for students and staff.
While the county mandate has been lifted, local city officials are calling for residents to continue to wear masks when out in public and social distance when possible.
"As mayor of Franklin, my first priority is to protect the wellbeing of our community," Franklin Mayor Ken Moore said in an Aug. 30 statement. "I respect County Mayor Anderson’s position and the decision he made regarding the mask/face covering mandate. However, I urge the citizens of Franklin in the strongest possible terms to continue to wear masks/facial coverings in public and in any area where appropriate physical distancing cannot be maintained. As your mayor and as a medical doctor for more than 50 years, I am imploring Franklin citizens to continue to do their part to fight COVID-19."
Moore said while the area has seen a steady decline in recent weeks, the county's number of active cases is still higher than when the county mask order went into effect July 8. Active cases on that day totaled 887.
"While this progress in encouraging, our community is certainly not 'out of the woods' when it comes to beating COVID-19," Moore said.
