I have found that a Northland thumper jig tipped w/ a 2"to 3" twister tail grub works well.Try various speeds and presentations to see what the fish "want".
Water on the flowage can vary to very clear to murky.When clear use more natural colors-black,blue,brown etc.... When murky go to more colorful bright colors that make noise.Good luck and remember smallies on tff are not always long but they sure can be some fat "footballs".
