CJ,
In Tennessee there are several larger reservoirs within a three hour drive from Clarksville. There is Old Hickory, Cheatam, J. Percy Priest, Normandy, Center Hill, Cordell Hull, Dale Hollow, Woods, Kentucky, Barkley, and Tims Ford. All will offer some good fishing with largemouth and smallmouth being the predominant species. Each lake has it's own characteristics: Dale Hollow & Center Hill are deeper canyon-type lakes while Kentucky & Barkley are shallow low-land types. The best thing about Tennessee lakes is there is no closed season on fishing.
