I fish Tellico a TON (1.7 miles from a ramp helps) and it's been a weird year for me as well. When I troll I long line troll under a float and my TOP speed on the Terrova is 0.6 mph but, on a glass slick, calm day I'll slow it down to 0.4 and hardly move the floats. I am really just keeping the lines tight and hardly moving. I've caught a bunch of fish on Tellico this year but, the shorts to keepers ratio is reversed this year. Last year I would usually catch 5-6 keepers before I throw back but, now I'm catching 8-10 shorts to a keeper. However, the keepers that I've caught are HUGE thou. Try Ball Play and go under the bridge and start slow trolling like I stated above in about 10-12 ft of water and see if you can't knock off a few keepers. I like blue and red 1/16 flies tandom rigged the best up there.
