I would have to recommend the Tennessee River system..below any of the hydro electrical dams is a good place to start. I fish alot below Wilson Dam,'cause it near my home town of Florence,Al. Been fishing there for 44 of my 47 years...we fish from a boat..fish can be caught from the bank,but its extremely rocky and hang ups are for sure to happen. There are several different way to fish below these dams, I believe if you were to interview fisherman at their boats when they pull their boats from the river you would be surprised at the different techniques used..rigs are different and bait is different. We use a simple three way rig ..three way swivel attached to the main line with a 18"-24" leader on the top, with 12" drooper on the bottom with a sinker. Sinker weight depends on the amount of current. Usually use a 1/0-3/0 Octopus hook. we bait with chicken livers, whole small shad, shad guts or cut skipjack herring..the cut skipjack seems to be the go to bait for the bigger fish. Some use whole bluegills...We run up near the dam and float back down river while dragging our offerings along the bottom. We catch blues and channel cats up to 7 lbs using this method. Bigger fish are caught tied to the dam and fishing straight down in the boils using saltwater style tackle, heavy line and cut skipjack. We also jug fish..when there are not many other fishermen, don't want to get in their way.
