Middle Tennessee has 18 "Permit Lakes" maintained by the TWRA. Boat ramps and picnic areas, some even have campgrounds. If you are under 65 the permit is 40+ $ per year or $5 a day, over 65 it's free. Bream, LMB, SMB and Catfish. The TVA Lakes are also well stocked. If you do any wade fishing the Duck River is a great warm water fishery, you can still catch Walleye up by Normandy Dam.
