text: how do i get in touch with the core of engineering park located below hartwell damn.?   it is listed as army corp of engineers savannah district.   706-856-0300 or 888-893-0678.  i found that sight last night because we are planning to go camping at tugaloo this weekend. it gives water temps and history of the lake. see below! it wont show entire link (?) but do a yahoo search for corp of engineers for lake hartwell and choose the site that says hartwell dam and lake homepage.
