The Army Corps of Engineers announces camping fee changes at campgrounds at both lakes Hartwell and J-Strom Thurmond. All camping fees for sites with electricity service have increased two dollars a night. All other campsite fees remain the same. At Lake Hartwell, fees to single sites with electricity and water hookups cost $24-$26 a night; double sites cost $48 a night. According to the announcement, the fee increase was the result of an annual assessment of camping fees charged by similar facilities in the area.
